Just to clarify the below alteration of the nested HashMap shows a compiler error, whereas the above does not not; with a Map (not hashmap)

Seems like I have solved the problem of strange checkbox behavior. First, the problem was happening because as soon as the listview gets resized, it redraws itself, therefore getView() gets called again for all the visible list items. Since I am using a ViewHolder, and the view is getting reused, it seems like it causes the same checkbox to get reused again for some other list item. So therefore, when I was clicking one checkbox, some other checkbox was getting clicked instead. Since, this call to refresh the listview was only happening when the list was being resized, and list was getting resized only on marking a checkbox in list when no other checkbox was marked, this problem does not appear again after the first checkbox has been marked.

I solved the problem by creating a custom collection class to store the checked items, and before putting the item in this collection, I clone the clicked checkbox's tag and clicklistener over into a new checkbox and store that new checkbox now into the collection. This solved the strange behavior of checkboxes. This may not be the best solution to the problem, so if you know anything better than this, please share.

Here is an alternative answer using the split() method only. (ie no delimiter needed). Note that with this solution, text with blank characters only are preserved.

SAMPLE CODE

OUTPUT

In my test, if you have exactly as many variables as items in your return, then it works.

I'm with the same problem time ago, you need to give privileges to the users to connect to the localhost, is different localhost from apache to mysql permissions

Possibly a security precaution. You could try adding a new administrator account:

It sounds like you are trying to write some error handling code. The compiler does do a great job of watching for inappropriate casts, but if you're looking for a runtime exception:

Nope! Git doesn't automatically stash local changes for you. Also, if you have uncommitted changes that conflict with the branch you're checking out, Git won't let you check out the branch in question. You'll need to either discard or stash them "manually" before checking out that other branch.

Yes, and there are good reasons for that. In particular, one use case for stashing is when you start doing changes while the "wrong" branch is checked out. You can then get out of trouble by

Yes, stashing your changes before switching to another branch, then popping a previous stash, would be the normal workflow. If you switch branches often, that can indeed be tedious, but if you use Git from the command line, you can define aliases in order to abstract some of that complexity away.

I've never used SourceTree myself, but I can imagine how that stashing/checking out/popping can involve quite a lot of tedious mouse clicks. Apparently, though, SourceTree introduced a mechanism called "Custom Actions" that allow you to define your own commands, including Git commands. You might want to look into it...

I've seen this happen because of an img tag with a blank src attribute. Giving an img, script, link or similar tag a src or href attribute ="" will resolve to the current page. So it will try to load the page a second time as it tried to load the asset. It could also be in a CSS url() property or an AJAX call.

One easy way to tell is to temporarily put something like <base href="http://example.com" /> in your <head> section. That will prefix any links on the page, which should prevent your local page from being called twice if it is that sort of problem.

I've also seen some browser extensions that query the page in a separate request. I've noticed this specifically with the Web Server Notifier and Web Technology Notifier extensions for Chrome. Try an "incognito" window or a separate browser and see if you get the same result.

I am not %100 sure why self.cleaned_data.get('repassword') returns None in that method, however clean_password is not the right place for performing validations of fields that depend on each other.

According to docs, you should perform that kind of validation in clean() function:

Please note that you don't have to implement clean_password and clean_repassword.

(If you think you still have to implement clean_password, you have to return password1 from it, not self.cleaned_data.)

As for the second error, the problem is, every time the validation fails you are returning a new fresh RegisterForm instance instead of the invalidated one.

You will need to use the ~/.ssh/config to specifiy the port. check the following link for a working example

I was having an issue with the same error when converting an Int to a custom enum:

The issue is that MyEnum(rawValue: 42) returns an optional. Force unwrap it with ! to allow switching on the enum:

It works fine if i use ResizeFill scale mode but i want to make the mode AspectFill so how i can make the edges with keeping the mode AspectFill?

Given a template metaprogram (TMP), do C++ compilers produce build statistics that count the number of instantiated classes? Or is there any other way to automatically get this number? So for e.g. the obiquitous factorial

I would like to get back the number 3 (since fact<3>, fact<2>, and fact<1> are instantiated). This example if of course trivial, but whenever you start using e.g. Boost.MPL, compile times really explode, and I'd like to know how much of that is due to hidden class instantiations. My question is primarily for Visual C++, but answers for gcc would also be appreciated.

EDIT: my current very brittle approach for Visual C++ is adding the compile switch from one of Stephan T. Lavavej's videos /d1reportAllClassLayout and doing a grep + word count on the output file, but it (a) increases compile times enormously and (b) the regex is hard to get 100% correct.

Also, i think the statements inside sub{...} runs only if pattern matches as per qr/($|#)/. Also, I would think that after you type in an input or command you would generally press the return key to execute the command hence the $cmd\n.

It is probably that you enter the value of letter without quotes. It then treats the content of letter as a function. Since it can't find the function, it throws a syntax error exception.

You need to have a separate cards array for each movie. One way to do this is to make cards a property of movie.

In the HTML, we modify it to pass movie to addCard(). In this context, movie is the current movie that the ng-repeat is iterating over. Without this, the addCard() function would not be aware of what movie it should be adding cards to. We also change the second ng-repeat to use movie.cards so that it knows to only look at the cards pertaining to that movie.

In the JavaScript, we modify the addCard() function so that it takes movie as an argument. We also need to change it so that it creates a place to store the cards for that movie

I just clear the @to field and return, so deliver aborts when it doesn't have anything there. (Or just return before setting @to).

Is onClick() supposed to be an event handler for a button click? If so, the signature is wrong.

I believe you are looking for something like this. I have changed it from an ArrayList to a generic List. And initialized it with a collection initializer, and made it accessible from within your function. Please run the code below and let us know if you get exceptions.

Hi all, this script (by Niklaus Gerber) works, but there's one problem. Once I set it up, it starts from CSS styles by covering whole page with div. Then script comes to uncover fully loaded site, however, it also locks browsers with disabled JavaScript (infinite loading).

Can someone help me to unlock those users, by changing this script or suggest me something more friendly for also those folks? (it's not online yet).

I am developing MVC4 application. I ended up with one complex scenario. I have following table in sql.

I am using mailgun (although this question has nothing to do with mailgun) to parse the incoming email and mailgun will http post the parsed email to my server. When I received the post, I got the html code for the multi-part email. I want to display the html email to my user, I am using rails, so it's something like

However, it looks different than it does when I view the same email in yahoo or hotmail (I know different email client will display the html email differently, but mine looks drastically different).

I use Zurb Foundation as my styling framework. However, I think the email html comes with its own in-line styling, I look at the code it does look like it does, then it should look similar enough with other clients.

So what is the best practice to display html email assuming you get a block of html code and want to display it as is without letting other frameworks overwriting its style?

Further more, is it possible to disable Foundation (or twitter bootstrap for that matter) styling for a block of code, for example, something like

As @Alex L. suggested, I tried but it doesn't quiet work as expected. The iframe renders everything in the view as before (see picture below), and that's understandable, since the iframe content is just the view of another controller, which in the case rails will include all the application layout templates as well. However, the toolbar is not my biggest concern, it's what's inside the iframe just looks exactly as before. enter image description here

I suspect iframe may not be the way to do it. I look at the code of both gmail and yahoo, and they don't use iframe. Instead they use very deep nested to render the html email. The part of the html email have the same code for both yahoo and gmail, except that yahoo insert an id of its own for every single DOM element.

Is it possible to create a static website redirect rule that redirects www.domain1.com/* --> www.domain2.com without maintaining the slug ?

I need to display profiling information pulled from a deeply embedded CPU, presenting it in a way which other developers on my team will be able to act upon. The profiling data is a snapshot of a cycle counter at the entry and exit of every function, so we have a call graph annotated with sub-microsecond timing accuracy. I'd prefer not to just dump out function names and timing like gprof, I'm looking for something easier to understand and act upon.

Has anyone worked with a particularly good profiling tool (on any platform), which made it easy to identify areas of the code to drill into? I'm looking for an inspirational example to follow for how to display the call graph, but if there is good tool with an input format I can massage my data to I'll use it. I could use Windows, Linux, or MacOS X to run the visualization tool.

A profiling article on IBM DeveloperWorks led me to GraphViz, with a profiling example on their site. Barring another suggestion here, I'll use GraphViz and mimic their profiling example.

Use the split method of the String class to split the input string on the space character delimiter so you end up with a String array of words.

Then loop through that array using a modified for loop to print each item of the array.

I find myself working for a group with a very large c++ code base that does not use Visual Studio accept as a compiler. We are using make files. I feel totally crippled without the visual studio advanced features such as intellisense, go to definition, and refactoring. Are there any good tricks out there to get Visual Studio 2010 to have these features without the projects and solutions? Or, baring that are there any good VI oriented alternatives?

ConcurrentModificationExceptions are fail-fast. So they are on a best effort basis. Essentially not guaranteed to throw up immediately.

I want this to happen if the build is in release. If the build is in debug, I want the un-minified individual files to load so debugging would be easy.

Currently In a delete controller action I do a schedule.shifts.clear() and then a schedule.delete(). This deletes the schedule record itself and the associations in th ejoin table, but the shift objects are still in existence. How do I delete these also at the same time?

It's quite hard to tell which assembly is "most useful" unless you choose platform you want to use.

If you go for PC (intel, amd) start with x86 assembly. There is a common instruction set for different CPUs + some technology specific instructions like SSE. If you want to develop for Windows have a look at MASM, for Unix FASM would be a good choice.

try editing the log4j.properties file which can find at the WEB-INF/classes folder. For client side you need to add a log4j.properties file to a class patch and set the properties accordingly.

Not sure about the core thing. But I was able to use it after uninstalling hyper-v. You can do so in turn on/off Windows features.

I am using Listview to display products list from database. OnPage Load products gets load properly but when I try to switch page using datapager pagination it gives this error

Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index at System.Collections.ArrayList.get_Item(Int32 index) at System.Web.UI.WebControls.DataKeyArray.get_Item(Int32 index) at shop.products_ItemDataBound(Object sender, ListViewItemEventArgs e)

Thing is if I use ItemDataBound then only I get this error. Else paginations works fine.

I just spent a half a morning trying to figure this out myself. The answer lies in the "Override default catalog from connection" about halfway down the Project|Properties|JPA page. You must set this to the actual catalog that holds your schema, typically the server name. It defaults to the username you provide for the connection.

I want to put each value in an array so I can use each do. So something like this:

I have tried using split() but the characters are not balanced on each side of the number. I also was trying to use a regex split(/\D/) but I think I am just getting worse ideas.

I have not tried the Express version, but I found this answer, which may be helpful to you (though it is for an older version):

I have very little understanding of javascripting so i would really appreciate it if someone helps me out

I'm creating a controller which will pull information of a painter from a database and display it: PainterController. I have defined it like so:

As you can see, a route is setup to accept anything like domain.com/painter/12 where in this example the id 12 is passed to the infoAction.

(FYI, I realize that the files are located in a public directory, this is due to a shared webhost constraint. The files are protected using .htaccess. This is unrelated to the question.)

Update: it appears that the above does work when defined in the bootstrap. However, I do not like to put a lot of logic in the bootstrap. Is it possible to define controller related routes inside the controller itself?

If you do something in sequence as you do in your code, then it is not a candidate for threading. Threads only help if something can be done in parallel, so in your case i.E. if you do not care in which order the numbers are printed.

density() does something similar, but it returns 512 values of the density evaluate at 512 regular intervals of x.

In both functions the number of points returned can be controlled. See argument gridsize in bkde() and n in density(). Of course, the precision of the approach does depend on the density of points at which the KDE is estimated so you won;t want to set this too low.

My gut tells me you may spend an awful lot more time thinking up and implementing a more efficient approach than you would spend just going with the above simple solution.

We need to design a server that will serve a webpage to several clients but also query a remote database for these clients. One of the requirement for this project is that the whole system must be compliant with the REST architecture style. We need use Java as programming language but many questions arised while we were designing it.

We want to have a main thread that will get connections, as shown in this example:

Then each connection will be created as a new thread (the Client object in the code) that will take care of reading ONE request. If the request is a GET, then the thread will serve the resource to the client. If it is a POST, then it will add the request to a buffer and let another thread handle the query to the database and also the answer back to the client. After handling this only request, the thread closes the socket and terminates.

Is the use of sockets violating the REST principle? In order to respect the REST architecture, do we need to destroy every Client object (thread & socket) after each HTTP message? Is there another way of client-server communication that does not use sockets?

These are my tabs, once I submit a form in the "contact us" tab, it goes back to the first tab. Can anyone tell me how to stay in the same tab?

(I used href not onclick in the listing. Stack Overflow doesn't allow to use more href so I changed it into onclick, before this post was edited).

jQuery.Deferred objects provide a very elegant way to do this (I know you're not using jQuery 1.5: I'm just giving you a reason to upgrade ;-):

... the alert will always fire after the first script has had a chance to define it's utilities no matter the order they load in. This has advantages over the setTimeout and event based approaches in that it's easier to have multiple dependencies (using $.when), doesn't use polling, and you don't have to worry about handling the order-of-loading explicitly.

As soon as I found django's cookie, I just add an attribute to the header of the adapter.

In your requirements, your explain that you want to allow a double click with a fast delay. But the e.getClickCount()==2 you use is not the solution for that because it's limited by your OS configuration. You can get it by looking the result of Toolkit.getDefaultToolkit().getDesktopProperty("awt.multiClickInterval")

A simple and good way to bypass the problem is that you handle yourself the delay between two clicks in the mouse listener. You could use a Timer where you can choose the interval max between your clicks and to handle by oneself the count.

The solution is rather simple. So since your code was testable, I modified it directly and i tested. It works for me. To summarize my modifications, I have added an boolean instance to count the current click count and have separated the double-click detection (technical) and the double click handling (logic) in two places. It's more readable. I have chosen 0.5 second as delay max authorized between two clicks. You can chose another value but if the value is too important (for example one second or more), it can give unexpected double clicks.

The problem is the where clause - you are giving it an expression that will evaluate to a string expression, but the where clause is used to specify conditions that must be satisfied to return records.

When you add new row in the table upon back button press, you can either add a new row in the table using

or update your array (adding this extra row) with the help of which you show the rows and then reload the table view. Because when you reload your table view, its datasource methods will be called again and then you need to return updated number of sections, rows and cell's

If you need to overlay the background image with a semitransparent color, the only workaround for one element is to create an image of that color and overlay that instead. But since you're trying to apply a page background, you should be able to simply apply the color overlay to body and the image to html:

Just keep in mind that body needs to cover the entire area of html as well, otherwise your color will only overlay part of the background image. The height and min-height styles above enforce this for height; for width, you will need to make sure body does not have any side margins or a width that's less than 100%.

See this answer for a more extensive write-up on both approaches to html and body backgrounds.

¹ _{It's understandably puzzling why colors are forbidden from any layer except the bottom one considering that color values with alpha channels exist and that you can still work around it with an image with the same alpha channels and the browser would still have to composite the background anyway. But that's just how it is, I guess. It doesn't look like this limitation is going to be addressed in Backgrounds level 4 either, so what do I know.}

I have a 46 MB csv file containing data. Essentially, I would like select only those rows that have particular word like "PRODUCT". There are 600 000 rows for this data. I have used grep() to search for the string matching. Following are few lines of my data.

But since you can't connect yet the easiest thing to do is go searching for sqlserver.exe, right click, properties, version. If you have multiple version you need take note of the folder that it's in and check the SQLExpress one. You can also check in services.

Once you've worked out the version, download and install just the management tools for that version.

How do I install flash player on ubuntu box so that firefox can load flash players correctly?

If you want to obtain single row totals - let your outer query aggregate data too. With appropriate GROUP BY clause.

You have already grouped data per ID, Location, Class and Date - now group by higher granularity level. It is impossible to obtain avg_phone_contacts_perid while you are requesting separate row per each id. Unless your desire is to see the same value of avg_phone_contacts_perid in every row (for example to make a comparison) - this is possible to do by windows function AVG(...) OVER (...)

The View component must contain sufficient logic to display the interface to the user. Depending upon the framework used, there can be quite a bit of code in the View. The important thing is to ensure business logic lies in the Presenter.

Regarding your secondary query, all Presenter methods will be invoked on the EDT when the View calls them (in the case of Swing). Unless the action required by the Presenter is trivial, I would immediately kick off a background thread to complete the work. That thread will update the View when completed using SwingUtilities.invokeLater().

In fact, to avoid being tied to Swing, I tend to pass my own EventDispatcher class to each Presenter. This is an interface with the same methods as SwingUtilities. I can then substitute in a different class if necessary.

Side note: this can make unit-testing the Presenter with JUnit difficult, because the Presenter method (and the unit test) will complete before the background thread does. I tend to construct each Presenter with an Executor that is responsible for running the background threads. Then, in a unit test environment, I pass in a special Executor implementation that immediately executes the run() method on the same thread. This ensures the unit tests are single-threaded. Example:

I am new in IOS developing. In Main.storyoard, I added a new viewcontroller, assigned it to a new class LoginViewController and provided a storyboard-ID loginview. In the LoginViewController class, after successful login I tried the following code to call the default viewcontroller having storyboard-ID webview.

But since you trigger it on resize, what's when the window width increases again? If you just want to hide the iframe on lower resolutions and show it again when user resizes back to higher resolution, then I would recommend to use hide() and show() (or use the answer proposed by @Sergey Kopyrin)

You can also specify a duration parameter inside those methods (e.g. $("#video-container").hide(500) ) so it will not be hidden abruptly.

I am initially seeking guidance to make sure I go in the right direction. From there I will come back with the code and ask for further assistance. I realize it isn't cool to say "hey I dont know what I am doing so I want you to do it for me."

So, here is my situation. I would say my php skills are amateur, and I am looking to increase them by working on projects for myself so I can learn through practice and application. I have created a webpage which contains a form that is used to update a XML file (I am playing around with flatfile DBs at the moment). All works well, the file is updated and the users is brought back to the page and the updated file is displayed. What I would like to do is allow the user to receive an update while they are browsing the website that the XML file has been updated, as well as alert them to the file update if they are returning to the website after having left.

My thoughts are that this would be done by using php session variables, one when they first access the website and another when the XML file is updated by a user. For the one when they access the site I thought a variable with a unique ID and timestamp as well as a timestamp of the files lastmodified value. I realize that this requires keeping storage of the session values since the value will have to be compared to something or else it will always appear as the most recent version, hence no changes.

Now that I think about it I guess you wouldn't need a session variable created on file update since the comparison will be based on the lastmodified value.

then you can really get any value knowing the line and the columns number lets say your data is

The format sounds like a good solution.
Perhaps a (few) nice regular expression(s) to cut your input variable into groups.

re.sub does not perform the substitution in-place. It returns a new string with the result of the substitution. You are free to reassign to the original variable name if you like, of course.

Check which svn commit caused the problem.

The commits are outputted by the git svn clone command, preceded by an r. The last commit that is outputted is the problematic one.

The next example shows what the git svn clone command outputs when begin procesing the Subversion revision 15 as the Git commit 373fb1...:

Split up the git svn clone command using the -r (revision) option

Supposing the revision 15 as the problematic one, and the repo in /tmp/svn/repo/, the solution would be:

the problem is the panel and the grid view are not accessible in c#? If I create the controls in designer, its accessible but throwing an error

Don't use eval for JSON parsing

It's very likely that your server will never become compromised, and that your application will be mostly secure, blah blah blah, that's not the point. It is possible for a server to become partially compromised (too many vectors of attack, what if the php json_encode function became compromised on your server?).

The simple solution is not to trust anything sent by anyone. Modern browsers have native JSON parsers, and www.json.org provides a long list of JSON parsers for various different languages. The JS versions will fall back on the native implementation for speed.

What all this means is that there's no good reason to use eval for JSON parsing.

I have a working sample on Github that supports inotify directory create/delete events. A small Watch class takes care of mapping wd (watch descriptors) to file/folder names. Here is a snippet showing how to handle inotify CREATE and DELETE events. The full sample is on Github.

returns a NodeList, i.e. an array of elements. You will need to loop over them and remove every of them on its own (but watch out, the collection is live and will shrink while you remove the elements).

Also, the getElementsByClassName may return elements that are no rows of that table at all, resulting in the NOT FOUND exception you receive.

However, the simplest way to remove rows from a table is its deleteRow method:

I had this problem and got around it by manually adding the Interop.ShDocVw.dll into the output directory.

I'm not sure Outlook 2007 makes use of this value (my guess is - it does not), but it's worth a try. My guess is even that Outlook does not care about the jpegPhoto if you put someone from the GAL to your personal address book. Anyway, this should be easy enough to test.

If all else fails, you are stuck with either making clear that it doesn't work or building a custom form that reads the value.

Build a generator of scale/object tuples, and take the max of that. By putting the scale first, max keys off that correctly.

At the end of the day, ORMs will always be slower than base SQL. Consider swtiching over to base SQL, maybe concatenating SQL statements so that you have fewer database trips, or using a stored proc, passing bactches of data to the proc and have it run the inserts.

Before you do a git push you have to do a git pull. Other person's work has to be merged with your code first and then you can push your changes to the repository. git pull will keep your updated code as it is and only add/update code (meaning that git will merge code) from the last commit (other person's code).

In case where both of the developers have worked on the same piece of code then git will show conflicts which have to be resolved first.

It looks to me like the code that works actually executes the block and the block's return result is the parameter passed to setRegion: where the second attempt passes the block itself as a parameter to setRegion:, which is of course expecting an MKCoordinateRegion as its parameter, not a block.

And (credit to MartinR), you can force evaluation of the block with an extra set of parentheses:

I want to display some drop-lists in the web page, so I created table, table body, row and cell with document.createElement() method; then I create the select elements and add them to the cells with appendChild() method. The web page can display the drop-lists.

Then I want to add a sentence to give user a hint, like "This drop-list is for xxxx, and you can use it to xxx". I decide to use label to do it. So I create a label. But I don't want to add the label to a separate cell behind the drop-list. I want to add the label just after the drop-list. So I use appendChild() again to add the label and select in the same cell - Firstly append select, secondly append label. But the label is displayed BEFORE the select in the web page.

Then I tried to append the label to the select as a child node of the select. Then the label disappears. Only select is displayed.

I'm a very newbie about HTML/Javascript/DOM. Maybe my thought is wrong from the beginning. Is there anyone can give me a way to implement my requirement? I just want to add a sentence after a drop-list.

Check for expired sessions on every Page_Init event. If there are too many pages to do this check, this is what I usually do:

You should be able to define a custom sort function that sorts by any item in your object. The key bit is to convert the object to an array in the filter function.

EDIT: In fact, it looks like your structure is actually already an array, so while this technique will still work, it may not be necessary - it might have just been the way you were adding the parameter to orderBy that was causing issues.

Suppose that data arrives from some provider like newVal = provider.getNext() and we can't go in reverse direction.

What is the most elegant and efficient (preffer object oriented) way to put incoming data in three structures:

Would it be better to use some switches/delegates or just buffer all data and extract parts wich we need in loops (assume that every value has the same type, let's say integer) ?

Assume that we don't need collect data in proper structure in real time (whole data can be buffered, but I look for efficient solution).

Real world data in this problem is a triple 'maps', each with size about 500x500 readed from .xls file in java poi extension if it matters.

This is very slow & incorrect way to create string from seq of characters. The main problem, that changes aren't propagated - ref creates new reference to existing string, but after it exits from function, reference is destroyed.

If you want to make it more effective, then you can use Java's StringBuilder to collect all data in string. (Strings in Java are also immutable)

X509EncodedKeySpec(key) or PKCS8EncodedKeySpec(key) constructors take private/public keys in encoded format. Unencoded key bytes can be converted this way:

Passing built-in types like int, char by pointer does not result in better performance results.

Using const keyword passing-by-value does not matter since original value won't be changed.

I have some documents whose ids are randomly generated. The issue here is I need to find the duplicates amongst these documents. I have three fields which should not be identical for two documents. So how to check for duplicates based on multiple fields?

Here as you can see, document 1 and document 3 are the same, but they are having different Ids in my database,so exist as separate documents. So on run I need to find the above as duplicates and if possible keep only one.

I'm trying to delete records from a database using SQLite/C# in Visual Studio 2012. Whenever I attempt to delete a record I get the following error:

I am wanting to delete records using two different methods. Either delete using only the EID, which is the primary key, or delete records where the user provides everything but the EID.

If you're trying to get rid of blank cells in sheet 'Belmont' column C, then this should work for you:

In the latest version of SymPy you will not obtain an integrated result unless you make the 'r' variable positive

Well SOAP uses XML as its data format. Not JSON. I would imagine that the issue is that you are getting XML back from the service and the "special characters" you're referring to are coming from that.

I know this is a late answer, but if you can always use sanitize-html It's written for node, but pretty sure you could run browserify against the library (or your code for that matter).

Note, it uses lodash, so if you are already using it, then you may want to adjust the package.

This example is more than you're looking for... I use this library in order to cleanup input code, converting to markdown for storage in the db from here, I re-hydrate via marked.

I often use this design in my code to maintain configurable values. Consider this code:

This way, I can save and retrieve values from files easily. The problem is that I don't want to repeat this code everywhere. Like as we know, enums can't be extended; so wherever I use this, I have to put all these methods there. I want only to declare the values and that if they should be persisted. No method definitions each time; any ideas?

I am developing a country specific website, for which I thought to have a geo redirection installed at my php server. The basic approach is to record the incoming IP address in $_SERVER['REMOTE_ADDR'] and then use a geolocation database to convert that into country information. I did go with Maxmind geolocation service. The final script that I came through with some google power and experiment power was as follows

index.php

BUT Something somewhere IS going wrong. The code doesn't execute, with a few errors each time. Have tried a lot many permutations of silly mistakes, but nothing worked. Calling the URL brings up the file geoip.inc's code on the URL.

Tried to find any similar questions on SO, but couldn't. A detailed help would be appreciated. Thanks in advance.

Search the Sqlalchemy documentation for enabling the logging of the generatef d SQL statements and Sql responses. This will usually give you all related information for further debugging.

Here, the problem with your code may be that there is a chance of any Player stored in an array getting over written. But, using vector, you can use const iterators and hence, make sure that they are not getting changed when you don't want them to.

Also, if your Player object contains any member pointers, make sure that you don't pass any Player object by value or do assignment using them. If that is the case, you might want to write your own copy constructor and assignment operator so that shallow copy does not occur.

As furas suggested in his comment, you could store the counter in the session or perhaps a database. You could also store it as a hidden input field on the form.

I have three pages in my portfolio website built on the Masonry plugin (http://www. 4pixels.co.uk/). On the first page fancybox works perfectly for a few of the images.

But when I use infiniteScroll to load page 2 at the bottom of the first page, the fancy box links stop working and just load the thick box image into a new page.

If I load page 2 (http://www.4pixels.co.uk/index2.html) directly into the browser it worked fine (with all the css/js). I've since stripped out the js and css from this page as it loads them from page 1, but it makes no difference and fancy box still doesn't work (The image to try it with is the Responsive screens for Winston Ellis website)

but still not working. I see your example is working so I'll have to pull it apart as I can't see were I'm going wrong..

I add a Converter in FormatterRegistry,but I don't know how to use it, can someone help me out?

I generated this class using SQLMetal.exe. It is very bindable at runtime, but if I use this class at design time, all of my design time blend bindings are busted.

If I extract an interface for this class, and create a simple POCO that implements this interface and I use my simple poco in my design time data source, all of the bindings come alive.

You should be able to use Dijstra's algorithm, where the nodes are "between" the cells of the matrix and the connections are implied by the weights of the cells.

The best way to deal with this is at compile time... if you get into the following habit you will catch that sort of mistake early:

by declaring variables as "final" the compiler forces you to give them a value. Since the buttons (and other GUI items) are not likely to change you should be able to make them all final. Once you have that you will have the com;iler help you out to avoid this sort of thing.

that has worked for me to get my submodule to the correct hash reference and continue on with my work without getting any further conflicts.

You could use the bitblt routines to merge an image to a common canvas, then save the image again.

I have the next list of carss whose header is clickable so it can be toggled on and off. Nevertheless, whenever I click on one of them, it turns gray. I would like to change this behavior and keep color unchanged.

But no luck. Perhaps this is not the CSS or I am not putting it where it belongs. I have tried adding it to ionic.app.scss (I am using SCSS instead of plain CSS).

I have made some SCSS changes on that file before and it seemed to work... what am I doing wrong now?.

Yes, you can using the flexible box model's order css property. Be aware that the parent element must have display:flex set

DS_RECURSE doesn't exist. It was a flag in a prerelease version of Windows 95 that was removed before RTM. All the docs that refer to it talk about "Don't use it", which is now very easy to do because you can't use something that doesn't exist.

The assembly bits are transfered into the database, the original DLL location is irelevant. The idea is that an SQL loaded assembly should continue to work after a backup and restore on a different machine, it has to be entirely contained inside the database.

Go to People - Permisions, find a module "User", find a line "View user profiles" and set permissions there for your user roles.

Obviously I must be doing something wrong, but I can't figure out what's wrong with this, it's driving me crazy.

You could also use a QStyle derived class, although this might be over the top if you really only want these round buttons and not tons of widgets with custom styling.

If a prod_no has both 'in warehouse' and 'not in warehouse', the MAX will return 'not in warehouse' as value. If you want 'in warehouse' instead, switch to min(t2.PROD_DESCRIPTION) in the sub-select.

Setting a bound property clears the data binding (for one way binding). I have never seen any Microsoft documentation on this but I have experienced it many times in my code and have come to accept it.

It makes sense if you think about it, since changing the property value means the property no longer reflects the value in the bound data.

I got this working in a Storyboard by checking Show Toolbar in the Navigation Controller. Then dragging Bar Button Items to the greyed out toolbar area now shown at the bottom of the Table View Controller. Then wiring the Bar Button Items up to methods Navigation Controller.

The unspecified behavior is not for the programmer to use (for the contrary if, for the programmer to known what it need to look with care and avoid), the unspecified behavior, as all the others: undefined, implementation defined, etc... are for the compiler writer to take advantage of (for example Order of evaluation of subexpressions have unspecified behavior, for that you should not pass any subexpression with side-effects in the evaluations, and assuming that you take care of this, the compiler reorder the evaluation of subexpression as more efficient it can, some subexpression can contain same calculation that can be reused and many other optimization can take advantage of the knowledge that can do evaluated in the best order it can find.

Here is what I ended up doing based on Wienke's recommendation. I added 3 prototype cells to my storyboard named Cell,Cell2,Cell3.

I also added this to check my dynamic cells and remove any lingering subviews that could be hanging around before adding the new subview.

You can create a simple authorization attribute filter (extend the AuthorizeAttribute class) and use it for your access control. Then try something like this:

The effect is that, POST and AJAX requests will always receive a 403 response which makes it easier for you to handle your ajax submits in javascript. As for the non-ajax posts, it doesn't really matter what the response is because your user shouldn't have got his hands on the submit form in the first place :)

As for the other requests, the method returns 401 that the formsAuthentiction module will pick up and then redirect your response to the login page.

I'm doing a cards game with 4 players where the backs of the cards of 3 of the players that the phone plays as are present on the screen with part of them outside. I've succeeded in doing this using the margins for the cards views for the top and left players but having a problem with the player on the right where setting the left margin for the card view just resizes it and prevents it from going off screen.

You could bootstrap asynchronously after your request(s) complete(s). Here is a sample:

I think EMD is good solution to resolve cross-bin problem compares with bin to bin method. However, as some mentions, EMD is very long time. Could you suggest to me some other approach for cross-bin?

I have an ObservableCollection of custom class that holds a string and an int:

I want to display the collection in a dataGrid. The collection has methods that notify whenever it has been updated, so so far it's only a matter of linking it to the DataGrid.ItemsSource (correct?). Here's the grid XAML (with dataGrid1.ItemsSource = files; in the C# codebehind):

Now things are more complicated. I first want to display the paths with the default values of occurrence of zero. Then, I want to go through every SearchFile and update it with a calculated value of occurrence. Here's the helper function:

Now when I run it, there are two problems. First, updating the progress bar's value throws the The calling thread cannot access this object because a different thread owns it. exception. Why? It's in a dispatcher, so it should work just fine. And second, the foreach loop breaks on the bool result =... line. I commenting it out and tried setting int occurences = 1, and then the loop goes around, but there's something weird going on: whenever I call the method, it's either all zeroes, all ones, or a between state, with onez beginning after a seemingly random number of zeroes).

I am reading HTML tables, and can do that fine, but I am collecting tables from multiple years. Unfortunately, the columns and rows are different in each year, so I wanted to add them all recursively to a list, so I can later apply lapply and do some analysis.

I can download the table and manipulate it into a dataframe when I do it once, but then when I add it to a list, the list only accepts the first column.

The issue is, I have many other tables that I would like to add, and was able to add them, but each one that was added only included the first column/element.

What is the most precise way to measure time intervals in iOS? So far I have been using NSDate to "mark" events and then timeIntervalSinceDate method to calculate the interval, but is there more precise approach? E.g. Windows has so called QPC for that kind of thing. Is there something similar in iOS (or MacOSX) world?

I have heard it is good practice to use some kind of document management system to keep track of different versions of your code/documents for school/work etc. I am still a student so my repository would just be local to my machine. I'm looking for some advice to get started/get in the habit of doing so. Im using OSX. What is the best/easiest client to use for my purposes? I've used SVN+tortise at work for years and it works great.

Are there any similar tools or APIs for browser extensions (i.e. toolbars, or filter systems like AdBlock)?

So I am making a spreadsheet with dates in them - for that I used a drop down calender, via the developer tab --> Insert more controls --> Microsoft Date and Time Picker Control.

In the spreadsheet, when it's not in design more, the date format is nice and normal but when I go to print the sheet, it looks like the picture.

Is there a way to turn off case-sensitivity in ReSharper when I search for a file by name -I mean by using the short-cut: "CTRL + SHIFT + T" ?

An invalidate queue is more like a store buffer, but it's part of the memory system, not the CPU. Basically it is a queue that keeps track of invalidations and ensures that they complete properly so that a cache can take ownership of a cache line so it can then write that line. A load queue is a speculative structure that keeps track of in-flight loads in the out of order processor. For example, the following can occur

A store buffer is a speculative structure that exists in the CPU, just like the load queue and is for allowing the CPU to speculate on stores. A write combining buffer is part of the memory system and essentially takes a bunch of small writes (think 8 byte writes) and packs them into a single larger transaction (a 64-byte cache line) before sending them to the memory system. These writes are not speculative and are part of the coherence protocol. The goal is to save bus bandwidth. Typically, a write combining buffer is used for uncached writes to I/O devices (often for graphics cards). It's typical in I/O devices to do a bunch of programming of device registers by doing 8 byte writes and the write combining buffer allows those writes to be combined into larger transactions when shipping them out past the cache.

I don't think that setMessageBody appends (nor its name indicates that), so I think you should construct the body first, using a string variable, and then set the body at the end of the loop:

I need just a few minutes for someone to tell me if these steps are correct for implementing cordova in a android webview:

1) I create project: cordova create hello com.example.hello HelloWorld and enter the folder

2) cordova platform add android, cordova run android (cordova.jar is created) => the app is launched => device is ready is shown

4)Import the project (as an "existing project" in eclipse) and add to the main java file after imports:

I am looking at getting python up and running with my WAMP setup. I need it to test some py apps I am learning to build. I see that Mod_wsgi project was terminated and that was pretty much the only way I found on how to run python on WAMP.

I'm dealing with a very big issue about bit rate , ffmpeg provide the -b option for the bit rate and for adjustment it provide -minrate and -maxrate, -bufsize but it don't work proper. If i'm giving 256kbps at -b option , when the trans-coding finishes , it provide the 380kbps. How can we achieve the constant bit rate using ffmpeg. If their is +-10Kb it's adjustable. but the video bit rate always exceed by 50-100 kbps.

When trans-coding is done, the Media Info show overall bit rate 440kb (it should be 320kb).

Is their something wrong in the command. Or i have to use some other parameter? Plz provide your suggestion its very important.

The problem was that when I applied the VS Update 3 on VS 2015 I did not check the Microsoft Web Developer Tools option. I had to do the following to get the folder and file in place.

Program and Features -> Visual Studio -> right clich and select change -> select modify -> check Microsoft Web Developer Tools -> click update.

After the update run the DotNetCore.1.0.0-VS2015Tools.Preview2.exe file again and select repair (this step is necessary).

This will create the C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\DotNet.Web and Microsoft.DotNet.Web.targets file

I'm using the following in the web page but can't get a response from the server while it's processing

The 'create' method in fmfiles_controller.rb then happily processes the file and gets the right results (as per the submit button on the form). If I uncomment the '//alert('Hello')' line I get a dialog saying Hello every 2 seconds ... as expected.

However, the server never logs any call to 'progress_monitor' method in 'files' not even a failed attempt.

it makes a call to the server, gets a response and displays the dialog, so I assume the routes and syntax and naming is all OK.

I really don't know why this isn't working. Is it because 2 methods in the same controller are being called via URLs?

I'm using Rails 2.1.0 in a development environment on OS X 10.5.5 and using Safari 3.1.2

(N.B. This follows on from another question, but I think it's sufficiently different to merit its own question.)

Basically it means you have a bus of wires, in which some bits are X (unknown), and others are 0.

If I saw this binary value: 0x0x0x, it would just mean that bits 5,3, and 1 are 0, and bits 4,2, and 0 are X.

I would like to know when the user from a command line presses control-c so I can save some stuff.

By using document.doctype.internalSubset, I have the following string, say str:

Note that I can use s.indexOf() to get the position of <!ENTITY and >, and then, use s.subString() to get the same result, but I'm learning regex now, so I want to use regex.

Thanks to Supr, I can finally figure out the error, it seems to me that, in this case, "*" doesn't mean "match one or many time", so instead of using /(?:<!ENTITY(.*?)>)*/g, we'll use this one: /(?:<!ENTITY(.*?)>)/g (supress the *) and then loop over the string until we get all result. Here is the source:

I am trying to post wall through my application with Facebook Graph API to user's fan page. Please give me ideas how can I past wall to the fan page using Graph API and without using the access token of fans page .

An alternative way: Put it in the resource file, if something change you don't need to escape it again.

You can use the HttpRequest.UrlReferer property. Create the single action in some controller:

I'm aware of the possibility to edit multiple lines on the same column by doing:

But I'd like to edit multiple specific locals addin new strings (maybe using cursor (h j k l) or mouse (with :set mouse=a)).

Like on this example, where I want to add the string 'XX' to specific locations. I.e.,

And %s is replaced with the content of a variable called $colname_article. Based on the name of that variable, I don't think it contains an integer, that can be inserted there without quotes.

If it is either empty or contains a string without quotes, it will result in the syntax error you saw.

Please note that this kind of dynamic SQL statements is prune to have SQL injection vulnerabilities.

Like many other out there I had the fun task of upgrading or TFS 2008 server to a brand-new TFS 2013 install.

The good news -> this has been done and documented. The bad news -> you have to migrate to TFS 2012 and then Migrate from 2012 to 2013.

All things said it mostly went fairly smooth. I cannot really complain. There is one hitch, however. Or plan was to use an intermediate server (SQLTFS01) for the TFS and SQL Server 2012 install and then most everything onto our destination server for 2013 (SQL008). Then we were to take SQLTFS01 offline and re purpose that machine.

In the end there was a missed step. It seems that our final install of TFS2013 is still pointed to SQLTFS01 for the reporting services components. See here:

Attempts to disable the reporting and analysis services portion of the server are all failing because even in order to disable the tool, it tries to connect to the existing tool.

Question: How can we disable this feature or redirect this stuff? Can we do it though setting files that I am not aware of?

i'm interested in this, but that's gonna be pretty hard because in the vertical view, you dont have any information about resource, the only thing is the generated/visual planning.

So there's probably a first work to do in the renderer to add this information on the column or on every slot...

Didn't have much time but i tried to start this, and i don't have anything working actually...

If any Fullcalendar master is crossing our way... Some help would be very appreciated ;)

No. Assuming that the logs are in base 2 then 2^log(n) mathematically equals to n, so 2^(log(log(n)) = log(n). And of course it does not have the same growth as 2^n.

No. 1.1^n is still an exponent by n that cannot be ignored - of course it is not a constant.

I suggest to take a look at the Formal definition of the Big-O notation. But, for simplicity, the top of the list goes slower to infinity than the lower functions.
If for example, you will put two of those function on a graph you will see that one function will eventually pass the other one and will go faster to infinity.

Take a look at this comparing n^2 with 2^n. You will notice that 2^n is passing n^2 and going faster to infinity.
You might also want to check the graph in this page.

The usual problem when trying to use an audio signal as digital signal input is that it is high-pass-filtered to avoid offsets (long term pressure changes which could destroy the dynamic range of the soundcards Analog-to-Digital converters). This means you will get only the changes of the digital signal (like "clicks"). Actually you will be better of the higher frequency your signal has, but it will be non-trivial to process it well then (this was what ordinary modems did very well).

If you can control the digital signals sent as sound (or to the microphone jack), make sure they are modulated the signal with one or more tones, like a morse transmitter or modem. Essentially you want to use your iPhone as an Aucoustic Coupler. This is possible, but of course a bit computationally expensive considering the quite low bandwidth.

There have been some cool viruses recently that was said to be able to jump air-gaps, they used similar techniques as this one.

Edited: or maybe not. position: absolute; is an option. To be honest, it is not clear which text is not meant to resize.

And the in your error page (should have one in the shared view folder) you can add the following line

Googling around reveals many people are having the same problems with Hibernate HQL not handling aliases very well. Apparently HQL only lets you alias a column that exists in a table. Also, HQL generates its own aliases for all columns in the query and these have the form col_x_y_ but how these are generated I don't know.

For my case I want to add two derived columns into a third derived column. Trivial in native SQL, surprisingly difficult in HQL.

By simply writing @synthesize usertoken;, an ivar is created that is also just called userToken (no underscore).

If you instead do @synthesize usertoken = _userToken;, it will work correctly.

I'm using Aquamacs (graphical emacs for OSX using emacs 24 and tramp version 2.2.3) to edit some files on a remote server. Tramp is set up to use ssh and works fine in terms of editing files.

It fails when it comes to compiling because the compiler is not in the path. It seems like tramp does not source any of the profile files like .profile or .bash_profile. /bin/sh is a link to /bin/bash so bash should be the shell used by tramp. A shell started within emacs on the remote server won't source anything, too. A ssh connection from a regular terminal emulator (tried Terminal and X11 on OS X) works as expected (everything sourced correctly).

I have got an issue on using the document.referrer property in IE. When I get to a page not through a link but changing the window.location through JavaScript, the document.referrer of the destination page is empty in IE7/8. Any idea on how to get around it?

The class at the bottom is an implementation of fast, thread safe, "lock free", lazy initializer.

I say "lock free", although it isn't completely; It uses a lock until it is initialized, and then replaces the call to get the data with one that doesn't use the lock. (Similar to a double checked lock with a volatile member; and from performance tests I get v. similar results.)

(After I had written this I noticed that the .net 4.0 has a LazyInit<T> which performs the same operations and more, but in a very highly contrived example that I created my implementation was slightly faster :-) )

NB Class has been modified to include Value member, and volatile on the _get

You need a log analyzer for IIS. Webtrends used to be quite popular. I used it a dog's life ago. Most use Google Analytics these days, but it's a different beast and tracks traffic, not data transfer volume. You really need to look at the server logs for that.

This, undocumented and unsupported, feature apparently never did work on Windows.

Instead you can use one of the pre-built runtime systems that loads a main.sav from the folder containing the executable. E.g. save your test.sav as main.sav instead and place it alongside sprti.exe in a folder that contains a proper folder structure for SICStus, as described in the manual, in the section Runtime Systems on Windows Target Machines.

The most common solution is to use the spld.exe tool an build a self contained executable but that requires the corresponding C compiler from Microsoft.

So I have a block of about 10 lines of code in JQuery. the lines are all independent, and when I execute them (I just type them in the console, its an automated test) i need them to be delayed form each other, like with 2 seconds difference. I started by using JavaScript setTimeout() on each line, but for 10 separate lines of code i assume there's a sexier way to do so... Also JQuery DELAY doesn't work since these aren't effects. Any ideas? here's the general idea of my code block..

As you can see all the tags and ID are unique... any idea would be greatly appreciated!

After Noogen's answer it got me thinking if Cordova needed to be updated so i grabbed the latest phonegap files and replaced the cordova.js file and the 2.8.1 jar file and then did a clean and build - it worked!

The JVM is a stack-based virtual machine. VMKit was an open-source project of LLVM which implemented a JVM with a LLVM backend. The idea of VMKit was to create a toolkit for building virtual machines (or managed runtime environments) such as JVM, CLI/CLR, R's runtime etc. To find out more, see Nicolas Geoffray's PhD thesis. While the project is retired, the source code is still available.

Also, Microsoft have released llilc which is a LLVM JIT compiler for IL/MSIL/CIL (which could be argued is a stack machine). The JIT code can be found here.

Even better, use DEFAULT instead of NULL. You want to store the default value, not a NULL that might trigger a default value.

But you'd better name all columns, with a piece of SQL you can create all the INSERT, UPDATE and DELETE's you need. Just check the information_schema and construct the queries you need. There is no need to do it all by hand, SQL can help you out.

Thanks for all the help, and the answer I selected most closely answers the problem of 2 emulators running slowly.

What it turned out to be was that I was using 767MB on an Intel HAXM emulator, and creating 2 of those went over the allocated amount for HAXM. After running 1 Intel and 1 ARM emulator, it worked. The error message was somewhat inconspicuous so I didn't notice it at first.

When you add a Script Task or Component to an SSIS package, there is a template in your installation folder that SSIS uses.

In there, you have a VSTA11_IS_ST_CS_Template.vstax file which is just an uncompressed zip.

The program wont let me use the input variable in mathematical operations, like g + 2

And I would like to offer my user the ability to see whether a website is secure or not.

How do I call a function from within the function, when I have multiple instances of that function?

Now I'm trying to get my head around how instantiation works in JS. I know I can create a new instance simply by calling new update(param1);, but then what's going to happen in the timeout when I try to call the update function? I can always just create a new instance every time, but isn't that inefficient?

If I could just call the same instance from within the instance that seems like it would be ideal.

You can also export template and then create a new project from the exported template changing the name as you prefer

I am trying to explore Serenity automation framework to test the application (built with SmartClientGWT) using SmartClientWebDriver

After adding a custom WebDriver (that returns SmartClientFirefoxWebDriver, because SmartClientWebDriver cannot be instantiated unfortunately) and setting it in serenity.properties file, I am able to execute a single test.

But now I want to mark my custom driver (SmartClientFirefoxWebDriver) using @Managed annotation to allow the Serenity Test runner to instantiate it before all tests are run. But it throws error:

You can do that without modifying the current implementation of NavigationDrawer, You just need to create a custom adapter for your listView. You can add a parent layout as Drawer then you can do any complex layouts within that as normal.

I have a 400 similar length columns with different lengths of NAs at the beginning of columns - How could I obtain an equal row length data frame that begins after the last row with NAs from any column.

This question is a bit older, but still the answer may help others. My Example also depends on Commons-Io.

You can create a ContainerRequestFilter and use TeeInputStream to proxy/copy the original InputStream:

And use @Inject with javax.inject.Provider in your ExceptionMapper to get the ContainerRequest injected.

When I have also used the @Component annotation my ExceptionMapper was not used. I think that @Provider is sufficient.

I'm not sure anybody is going to write the code you need. Casperjs has pretty good documentation. You need to request the page, find the id's of the login and sendKeys. I haven't run into any issues of not being able to log into a web based application using casper. IF you're completely at a loss I have a video you can watch which enters data into an Ajax application, which shouldn't be too much different than what you're trying to do. Filling out Ajax forms

Using the BufferReader/InputReader(System.in) classes is a good alternative to using the Scanner class in the sense that code operation is not blocked while waiting for input from the User. This is why the while loop is in play so as to actually wait for User Input. While waiting for User input, several things such as running other code can take place including the start of other Threads etc.

On the other hand, when using a Scanner object, to get input from the User you might have:

When the scan.nextLine(); method is encountered code is completely blocked until a User enters something into the Console unless special Thread & thread locks have been put into play within your code. As a simple example, try yourself to set up a console User Input request which only gives the User 10 or 20 seconds to provide that input and upon timeout the application closes (perhaps for a login or whatever).

This is difficult to do using the Scanner object (but not impossible) since when the input request is issued further code operation is blocked yet with BufferReader/InputReader this is relatively simple to carry out since code blocking is done with your own code (usually with a while Loop). Below is a simple method example which allows you to ask the User to provide input but with a time limit:

Just for the fun of it, try to accomplish the same task using the Scanner class.

As for the code block example you posted, it looks as though it simply asks the User to enter a continuous series of strings. The while loop within the code continues to accept input from the User (once the ENTER key is hit) until he/she enters null (which they can't, CTRL+D or CTRL+Z doesn't always work). At this point polling for input is halted (the while loop ends) and the input which had been placed into a String List Array is iterated through and displayed within the console window. What you want to do with the strings contained within the List array is entirely up to you....save it to a file, display it within a JTextArea component, whatever.

Now...there is a bit of a flaw with the code and the problem lies within the while loop condition. While the User is providing input he/she is permitted to continuously enter strings until the cows come home but there is no way to satisfy the the condition within the while loop. The is no bulletproof way to provide 'null' to the console so that the rest of our code can be run which iterates through the List<> array and displays each element which consists of strings the User previously entered. The solution to this is to supply an additional condition which permits the User to enter the word quit so as to indicate "I'm done making my entries...do your thing". So we change the while Loop to start like this:

Now, if the User enters the single word quit (regardless of letter case) we exit our while loop and the remaining code is run. We don't want to use a Null String ("") for this because we might want the blank lines provided by the User during the text entry which is usually done when starting a new paragraph for example.

Do you think it is alright from architectural stand-point to have ViewModel - View without model for temporary things?

E.g.: I want users to input some paths so I can open some files later on. It doesn't make sense for me to store the paths anywhere just ViewModel and when the user clicks "Show all files" I then construct models of the files and ViewModels for View that represent them somehow. So really my only model is the model of the file.

I would look into a Mobile Device Management provider such as Silverback (http://silverbackmdm.com/), or Zenprise (http://www.zenprise.com). Microsoft is also releasing an extension to Intune services in 2013 for MDM too.

The MDM providers allow the enforcement of device security policies, including thins such as remote wipe, password enforcement, etc. It's a great way to manage BYOD policies.

Showing what a novice I am with Objective C here. The second of these two methods is getting called by the method above. Though I have absolutely no idea where? I want to be able to wrap the part that calls the second method in an if statement to determine if the file did exist based on the returned Boolean. Example code would be appreciated, if anyone could also explain how this second method gets called that would also be fantastic.

If you use Microsoft Network Monitor or Wireshark to capture the packets, you may gain more insights on packet level.

In this case, CRL is necessary as it is enabled by default. But you can turn it off on machine or application level,

While it's possible to argue that double-clicking the map or wheel-zooming the map need not take account of the mouse location (because you are acting on the map object rather than a location on the map), pinch-to-zoom is always location-dependent because you physically stretch or squash the map around a location. To alter that behaviour would be distinctly unintuitive.

In this case you should listen for zoom_changed or idle and then pan the map to recentre it, so the user can see what's going on.

You could even use those events to handle the default double-click or mousewheel behaviour so that it's obvious you are changing the level of control the user normally has.

I'm using angularstrap typeahead for autocomplete suggestions via $http. Demo here.

Everything works fine but everytime I type a letter, a call is made. Even if I set a minLength of 3, a call is made for length one and two.

How do I prevent that behaviour? Other thing that happens is when template/controller is loaded, the function getAddress is called...

synchronized on an instance method does just serialize calls per instance, synchronized on a static method would do that per class, hence for all calls. So they have different lock objects. As one can guess now, a static synchronized method may be used to modify those static fields.

That's because the Javascript engine is built into your browser. CURL does not know what Javascript is.

What you need to write is called a "shell script" that can be initiated with a cron task.

how can i change the size of button in alertdailog in code without using xml ? I'm not using view ..

Thank you The code :

alertbox3.setNeutralButton("Cancel",new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { } });

I don't believe so. As you alluded, it's easy to use ZipFile with an actual file on the file system, but not so for a file embedded in your application.

For accessing a zip file in your APK, you'd have to use something like Resources.openRawResource(R.raw.zip_file) and then wrap the returned InputStream in a ZipInputStream and do it the usual Java way, rather than with the Android method.

Alternatively, if you really find you need to use the ZipFile class, you could extract the zip file from the APK to the SD card or, more reliably, to your application's local storage.

but in my html I want to show the script src="testing.js" I am able to somehow put the first two links into the testing.js file?

sims like this plugin help you. For landscape you have to use screen.lockOrientation('landscape'); in controller. And on other page if they are not in portrait view you have to put screen.lockOrientation('portrait');

1 million entries containing words shouldn't be slow if you have an index on the word column. This is because the words would be pretty short but with enough entropy (statistical dispersion) to leverage the key.

If this were 1 million phrases, comparing the phrases might have taken a bit longer and in order to optimise you could've broken the phrases down into the first 3 words (in different columns) and a column for the rest of the phrase with 4 column index over them.

The speed I clocked on my laptop was initially 80.765522003174 seconds, and I've done 10 tests and the average is around 93.478111839294 seconds for the 1million select statements, meaning 1 tenth of a millisecond for each select.

Take into consideration the fact that I clocked it from PHP that means that the actual SQL execution speed is much higher, the 93.5 seconds include PHP communicating with MySQL over TPC.

I have inserted an extra 9million values into the table and tested the same script running 1million select statements against 10million values. The overall duration is around 52 seconds.

CSSEdit + Adobe Dreamweaver + TextMate + Transmit FTP + Firefox with FireBug and FirePHP and you good to go on MAC ;)

Remember that the String.replace() javascript method is actually like a combination of PHP's str_replace() and preg_replace() - the first argument can be a regex as well as a string. So you can also do:

You'll have to query for the Queryable.Where method being called as you crawl the Expression tree.

Also note that while Queryable.Where is going to be the most common way to detect a where filter, query syntax allows for other implementations to be used (depending on what namespaces are used in the using directives); if you have something that is not using the Queryable.Where extension method then you'll have to look for that explicitly (or use a more generic method of filtering for a Where method that takes an IQueryable<T> and returns an IQueryable<T>).

The ExpressionVisitor class (as pointed out by xanatos) provides a very easy way of crawling the Expression tree, I highly recommend using that approach as a base for processing your Expression tree.

Of note is that ExpressionVisitor class implementations are required to store and expose state on the class level. Because of that, it would be best (IMO) to create internal classes that perform the action one-time and then have a public method which creates a new instance of the ExpressionVisitor every time; this will help with dealing with mutating state, and if done properly, will allow the method to be thread-safe as well (if that is a concern of yours).

I've got a table of stock market moving average values, and I'm trying to compare two values within a day, and then compare that value to the same calculation of the prior day. My sql as it stands is below... when I comment out the last select statement that defines the result set, and run the last cte shown as the result set, I get my data back in about 15 minutes. Long, but manageable since it'll run as an insert sproc overnight. When I run it as shown, I'm at 40 minutes before any results even start to come in. Any ideas? It goes from somewhat slow, to blowing up, probably with the addition of ROW_NUMBER() OVER (PARTITION BY) BTW I'm still working through the logic, which is currently impossible with this performance issue. Thanks in advance..

I tried to make Icon.png and Icon@2x.png localized, then I tried to make the proj-Info.plist localized and try to link to different Images.

I believe you need the scale_numeric argument with reverse = TRUE to flip the order of the range.

First of all, A lot depends on with which controller is your UIViewController embedded in.

Eg, If its inside UINavigationController, then you might need to subclass that UINavigationController to override orientation methods like this.

subclassed UINavigationController (the top viewcontroller of the hierarchy will take control of the orientation.) needs to be set it as self.window.rootViewController.

From iOS 6, it is given that UINavigationController won't ask its UIVIewControllers for orientation support. Hence we would need to subclass it.

Then, For UIViewControllers, in which you need only PORTRAIT mode, write these functions

Now, if you want to do some changes when Orientation changes, then use this function.

If you want to provide only Portrait mode for all your viewcontrollers, then apply the portait mask. i.e UIInterfaceOrientationMaskPortrait

Otherwise, if you want that some UIViewControllers stay in Portrait while others support all orientations, then apply an ALL Mask. i.e UIInterfaceOrientationMaskAll

As BoltClock mentioned that png files are compressed, but you can view it on MAC using a little application called iphoneapp , i use it regularly and found it useful

Summary: It works, git-p4 is a great tool, very intelligent, comes with lot of configurable options. Multiple branches scattered wherever across depot tree migrated successfully. We need to run the import at highest level (topmost) perforce directory that covers all sub-directories or branches of interest. For efficient operation, suggested to use --changesfile option, to explicitly specify changelists to be imported. Also use git-p4.branchUser and git-p4.branchList to explicitly specify branchspecs.

Details: Here I am showing the settings that worked for me. There may be a better way to achieve the goal.

Perforce client: This is set at highest (topmost) p4 directory. This is very important, otherwise git-p4 may exclude changelists (restricted due to client view) as empty commits.

Perforce branchspecs: I created a single branchspec that covers all my branches dependency (parent/child) information

git-p4 config items: Next, I setup an empty git repository and following config items.

( ** branch information, dependency relation, interestingly only last name (directory name in branch path) is required to mention, git-p4 automatically detects/pick what is required i.e. fully expanding the branch name )

Changelists file: Next, I collected all the changelists, for all branches those I am migrating.

On smaller depots “ ../git-p4.py sync //depot@all --detect-branches --verbose “ shall also work, in that case no need to create changelists file (earlier step)

Once import is finished, I am able to see git-p4 created all remote perforce branches inside single git repository.

Next I simply added a remote origin and pushed the code into git repo.
Thanks for various pointers/help available in stackoverflow and online.

POSTBACK: Part of ASP.NET's contrived technique for hiding the true stateless nature of the web/HTTP behind a stateful facade. This results in complex code (IsPostback, ...), a hard to understand page lifecycle, many different events, ... and numerous problems (ViewState size, web-farm stickyness, state servers, browser warnings (not using PRG pattern), ...)

My question is, in any of the examples, A, B or C - since the string would not be used ultimately would the optimizer remove it?

Or asked another way, would it be better to do the following, thus ensuring that the string objects would not be created?

The source workbooks must be replaced from time to time and some of them sometimes are just erased.

For those cells in the main workbook linked to deleted source workbooks I was expecting to get "#REF!", but instead I get old values, from the deleted workbooks.

Is there a way I can get rid of old values and get "#REF!" or blank cells instead?

I'm have a problem with file_get_contents() - on my old server everything works fine, on my new one it throw 404 error on some URLs I'm trying to get.
All the URLs are from the same website and in the same structure - but some gives me this message:

I have DirectAdmin with his basic configurations installed on the new server, while on the other I have cPanel

gen.flow_from_directory gives you a generator. The images are not really generated. In order to get the images, you can iterate through the generator. For example

They way I fixed is was by adding autocrlf = input , safecrlf = false on the git.config file

It sounds like there are currently some issues with scaffolding when the models are located outside the current project. As a workaround, you can add the model temporarily to your web project and then move it to the BLL/DAL projects after scaffolding.

Example of issue my team were having with this sort of setup (not exactly what you're coming across, but I think our setups are similar enough and the problem might be due to the same issue): https://github.com/aspnet/Scaffolding/issues/249

So I suppose up until 1.0.0-preview2-update1, this will remain an issue so long as you have a project that splits things out into more than one assembly. In my case, the project setup is too complicated to copy things into one project... So I can only bang my head against the wall :( and start typing the scaffolded code.

You seem to store empty string ('') rather than NULL in the empty fields. Those are different things in MySQL.

By using "greater than" you give MySQL posibility to use an index range scan on cssstyle

When I follow the link given in terminal it also gives directs me to a blank page. But if I copy and paste the link into my browser it works fine. Dont know what is happening there...

Ps. I would/should have commented on, not answered, this question. But my reputation is too low.

While loading a web site, I often have the need to load code AFTER some other DOM structural event has occurred. Therefore I often end up with a lot of functions that first check if some element exist in the DOM and then do their thing in the event that said element exist.

I think I like this pattern as it lets me write fx that keeps trying until the DOM is in a state where the function can succeed (return true); without having to go through a great deal of ceremony in terms of dealing with retrying (just return true on success).

I am looking for improvements to loop-until-true, a function that registers another function to keep executing until that function returns true. I don't want to actually block the execution of the code that might cause fx to pass, so I am using a core.async block to IOC the code. This code seems to work, but I am looking for improvements and critics.

It makes sense if you are likely to perform lots of small reads (one byte or a few bytes at a time), or if you want to use some of the higher level functionality offered by the buffered APIs; for example the BufferedReader.readLine() method.

However, if you are only going to perform large block reads using the read(byte[]) and / or read(byte[], int, int) methods, wrapping the InputStream in a BufferedInputStream does not help.

(In response to @Peter Tillman's comment on his own Answer, the block read use-cases definitely represent more than 0.1% of uses of InputStream classes!! However, he is correct in the sense that it is usually harmless to use a buffered API when you don't need to.)

If you already have a retrieved author and you want to get the article count then using the related manager's count method (author.article_set.count()) is probably okay.

On the other hand if you are iterating over an (possibly lagre) Author queryset just to get the counts, it will do a lot of queries (one to retrieve all authors and one per author to get the count). This can be easily replaced by an annotated queryset that will result in only one query:

Later on in your in your template you can just use {{ article.author_count }}.

Google not only prohibits direct personally identifiable data, but it also prohibits data that can be used to indirectly personally identify people within your own system. So in other words, if that GUID is attached to a personally identifiable info within your own system, you cannot send that data to GA, because you can easily export the GA data, tie it back into your system, and attribute GA data to personally identifiable data.

Of course, someone would have to bring it to google's attention, and someone would have to prove there is a link to said data...

If I understood your requirements correctly, you can first let your lambda functor accept an argument of the appropriate type (passing by reference here, so take care of lifetime issues):

Then, your doSomething() template function could use std::bind() to make sure your lambda will be invoked with the appropriate object as its argument:

Data<void *> obj; constructs a Data object to store void * type using the parameterized constructor passing new Data as the parameter value. obj itself needs to be a pointer:

You can show any kind of UIViewController in a UIPopoverController. A table view is not at all required for displaying a Popover controller. If you want to display a UITableviewController, you most certainly can. Just pass it in to the popover controller.

If this is a known bug in the datdgrid then i would consider hacking a if-it-looks-right-it-is-right solution (i think this beats modifying/fixing a dll).

Examples, does it must be a hyperlink? Can it be a textblock instead (which you'd handle the hyperlinking part in code)?

I need to remove the 1 to 4 digits record number (i.e.: 5145) and any notes such as "Nota a data: extraída do listado de compra" which always come at the end of the record, after the signature (-----FOT-xxxx--) and before the next record's record number.

I've been trying to write an awk program to do this but I don't seem to be able to grasp awk's syntax or regular expressions at all.

Here's my attempt to match record numbers, those lines consisting of 1 to 4 digits only. (I think I'm missing the "only" part).

but I don't know how to remove the lines in between those and the record numbers.

Excuse my English and my repeated use of the word record, which I know might be confusing given the topic.

I have a page with some tabbed content on it. A couple of the tabs contain iframes and I use a handy little script to resize the iframes to suit their content. It's

Today I have added a little jQuery script to stop the tabbed area showing until it is fully loaded. This stops the tabs doing an unsightly little jump when the loading is complete. This is the script:

The loading div contains a loading icon and the tabber div is the entire content of the tabbed area.

This script is also stopping the iframe resizing working. In order to understand it better I added another script:

Sure enough, "win" comes up as zero. If I delete the $("#tabber").hide() line, "win" shows a sensible number for the height of the iframe.

Vlad produced the solution: I had to use the jQuery version of visibility=hidden instead of the jQuery version of display:none. That doesn't actually exist in jQuery so I found out from another StackOverflow question how to write my own functions to do it.

My thanks to Vlad, and also RAS, for taking the trouble to look at my question and give their ideas.

You can use the Java library from here: http://www.johannes-raida.de/jnetcad. As far as I can see, it should support JT version 8 files. I used the DXF import library and was quite happy. The API is the same, so you have access to all triangles with their coordinates, normals, color and layer.

I would suggest you using stanford Name Entity Recognizer(NER). Stanford NER provides many classifiers.One of the classifiers provided by stanford NER can identify name,location and organization from a given text.

I have created a function to scrape statistics from individual soccer match reports. I am usually able to use this to scrape stats from hundreds of matches at a time without a problem. However for the past week I have been away visiting family for the holidays cannot run my code at all without receiving the message:

I thought this was just my parents poor internet connection but I am now having the same problem wherever I go around the country!

Could someone please help me by helping me understand what might be causing this? As far as I can see nothing has changed in the websites I am trying to scrape. Is it something caused by the internet connections I am now using? Is there a simple fix I can add in to my code to overcome this?

As mentioned, I am able to run this on hundreds of matches at once on my own connection at my flat so I am very confused!

About animating the border of a TextBox (presuming input:text or textarea) cross-borwser AND cross-platform is impossible. For a lesser scoped of browser, per say, modern browsers, there is css-level3 with border-image.

About displaying a progress bar upon a TextBox, it will be quite easier, especially if your content is loaded via AJAX. It's all about a container displayed position absolute left top. Then the css animes the container.

Of course you can do <img src="src" style="width:100px; height:auto;"> and changed width and height to 100px accordingly.

If you are trying to run app in device than check all cerficates are verified and uninstall app and try to run again.

You can create your own category to be able to get array of touches that is declared in the UIPinchGestureRecognizer interface

Then, when you create your gesture recognizer, you set callback to it, that will receive recognizer as parameter. Using category method, you can get all info (you need positions in this case) for every touch and process them to determine needed rotate angle.

I want to develop web app with spring boot and i want to address my javascript and css resources in jsp files. i config my access to this files from jsp in dispatcher-servlet.xml like this:

if ya have just one Activity override the OnBackPress event and do your thing just return or something.

Unfortunately attributes are just metadata, meaning they cannot run or do something on their own.
However nothing prevents you from writing an extension method with a name like SetDefaultValues that reads default values from attributes and assigns them to properties.

I've done a similar thing in a recent project, and it proved to be a good decision because it kept all default values defined in a declarative style in a single place.

There is an interesting article on CodeProject peering into different strategies for implementation of [DefaultValue]-based initialization and comparing their performance. I suggest you check it out.

1st thing Id check is- Open up your flat file connection manager, select the column that's being imported and see what the data type is set to -

I am using a combination of doc and xpath objects to extract the attributes and node contents.

But, when I say get elements of tag name CourtID, it will get all the CourtIDs, not just the ones under USBankruptcy.

I can not fully explain it, but the problem seems to be that session.downloadTaskWithURL(url) returns an instance of some internal subclass __NSCFLocalDownloadTask.

If you define the extension as an extension of NSURLSessionTask instead of NSURLSessionDownloadTask

I came across source code of AtomicInteger class on GrepCode and found following code snippet.

How the static block know the offset of instance variable value . Static initialise when class is loaded and linked . so how can we know about the offset of the instance value at class loading time . Object are created after class loaded . Is that "value" instance variable will have fixed offset when ever object is created. Please explain .

I am trying to connect to the Meetup streaming HTTP API and parse the received events in different records. I am using ruby over Sinatra. I chose the 'em-http-request' gem to handle the connection and 'thin' as server. Searching for info on how to handle an API streaming all that I found was about 3 to 6 years old and this is the best example that I found.

In this example the author uses a regex to find the end of each tweet and split them into different records. In my case I didn't find a way to split the stream of meetUp events.

I open the conection calling to //stream.meetup.com/2/open_events and I start to receive an stream of strings randomly cutted with this format:

I tryed to use .slice! over the content of buffer using as param "{"utc_offset"" which is the substring that appears at the beggining of each event but I couldn't figure out how to write the regex that gets everything enclosed between each apeareance of the substring to get as result the whole event.

Also I am not sure that adding the chunks to the variable buffer and then use of the method .slice! it's the best way of getting each event.

HERE I ADD THE IMPLEMENTATION OF THE SOLUTION SUGGESTED BY @jordan IN THE COMMENTS:

I want to compare that time with current time. If that difference is above 60 minutes. It will return some value.

I have old date&time is in $lastUpdatedDate variable, and current time is in $nowDate.

You can set the NSWorkspaceDesktopImageScalingKey in the option parameter. Here's the possible values:

If it is too large for the destination, scale the image down while preserving the aspect ratio.

Scale each dimension to exactly fit destination. This setting does not preserve the aspect ratio of the image.

Scale the image to its maximum possible dimensions while both staying within the destination area and preserving its aspect ratio.

Easy way to track any change in anywhere... Many framework with 2 ways data binding, use keyup in Javascript to $watch the changes...

Also jQuery UI date-picker has onSelect...So easy way to do ur job... look at https://jqueryui.com/datepicker for more information...

In this specific case i think there is a guarantee.
Some queries in Hive won't generate MR jobs and instead will IO the table directly in a serial way.
In your case, querying select * from table will not generate a MR job (unless table is a view).
Reading the table with a single process, reads from the first file to the last and from the head of each file to the end. hence, I believe that the order of the output in this way will be the same whenever you'll run the query.

The selector needs to be circle:nth-child(3) -- the child means that the element is the nth child, not to select the nth child of the element (see here).

The json u r passing is not proper. It has an extra comma ',' after price: 12.50. Even after second price element also an extra comma is added. Just remove it and it works fine.

I know this is a very broad question on how to prevent an Android app from crashing. I understand there could be many reason behind the app crashing.

1) Out of memory while taking pictures and storing byte array in memory. I also uses bitmap to redraw the image captured.

2) Camera issues. App has a feature of autofocusing on touch events and while actually taking the pictures. These autofocus often crashes into each other. I have handled it using cancelling any existing autofocus code and discarding any further on touch events using flags once the picture is being captured. But still some time app crashes due to unknow reason.

1) Is there a way I can identify that app has crashed and handle that event so that instead of just showing the messsage ""UnForunately App has stopped working. Force Close." I can give a better user friendly message to user and stop the app programatically.

2) If out of memory every happens, is there a way I can identify that my App is running low on allocated memory and I can handle the scenario. OnLowMemory will give the low memory status of entire device, not just my application. I use lot of cache to store the images & heap for bitmap.

3) If the camera ever crashes (because of any reason), is there a way I can handle the scenario.

If I use getenv() to disable some verifications of my program (for instance license checking) will a hacker be able to discover easily the concerned environment variable (using strace or other ?)

(If, on the other hand, I checked the presence of a specific file, the hacker would see it immediately with strace)

When you move the files to the production server you don't have to copy configuration.php that store the variable for robots in public $robots = '';.

I highly recommend you to keep your development installation htaccess password protected to be sure that would never be accessed by search engines.

There is an error in the placement of the 'projection' attribute. The answer below shows the correct one.

I'm trying to test a site like sample and get different outcomes when clicking a button. When running selenium webdriver's --firefox and chrome-- I get redirected after this click:

However, if i go to the site and run the following command in the console, I do not get redirected.

What is causing redirects to the homepage when running on through selenium? A thread.sleep command won't work and wait_until isn't working either. My guess is that something is happening too fast...

The above bash script which gives me user name of IP (1.1.1.1). I would like to pass the IP as a command line argument. I tried,

Hope i'm passing the command line argument correct. But not sure, why does this error pop up?

The use of $xml variable looks like it is loaded with SimpleXML extension. Suppose it is initialized like this:

Then you just fetch attributes with attributes() and check if the attribute is in the returned array:

To expand on that a little - here are a couple of the relevant POSIX definitions:

It seems somewhat circular, but there is nothing special about a "pathname" in the context of the argument chdir(); it is subject to pathname resolution as normal.

Although alert(some_array) prints a string representation of the array, the array itself is not a string. Thus, it does not have .replace. alert is forced to convert it into a string because the alert box can only show characters.

You can simply join using a custom separator, though. join is a function of arrays:

Ideally, you would be able to specify an external "binding" for the env-entry. I know that's possible to do with WebSphere Application Server (via EnvEntry.Value properties), but I don't know if it's possible with Glassfish.

As a workaround, you could declare the env-entry for injection, and then check in PostConstruct whether any value was injected by the container (i.e., don't specify env-entry-value until you're deploying into the server). If you're using JNDI only, you can do the same thing with try/catch(NameNotFoundException).

I allways get this

java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.Context android.content.Context.getApplicationContext()' on a null object reference

error while I run my app. I saw other answers but I didn't understand how to use those answer, I understood that there is some problem withe the context because there isn't call by Activity, so I also tried to pass the Activity context with no success... this is my code:

EDIT I already did your answers and it'snt worked, so I deleted this becuase I thought it'snt the solution. Due to yours answers I updated the code(with context as parmerter to the Distance class >to MySingleton class...)

You will need to set the flag called ecoReinstallInstalled (Installshield help does not mentioned this keyword) which is referred to in the document titled “Using Chained MSI Packages to Componentize Your Windows Installer Setup”.

Basically, you change the ‘option’ column of the ISChainPackage table of the specified chained MSI by adding the value 16 to the current value. If the value is less than 16; for example, the value is 0, replace it with 16; if the value is 1, replace it with 17 and so on. The option value determines the UI Level mode (the mode in which the chained MSI will run); 0 for Basic UI, 1 for No UI, value 16 or above will allow the chained MSI to re-run after it has been already installed.

If this does not work, which it should you need to check the chained MSI's log file by modifying the property IS_CHAINER_POST_COMMANDLINE, you could also try running the chained MSI in ui mode to see what the behaviour is.

Interestingly what alternative did you use instead of the Chained MSI functionality?

When you increment the value of MIN_STACK before inserting, you always leave stack[0] empty and waste the space. Also use MIN_STACK as your index and not MAX_STACK as the value of MAX_STACK is always 10.

In POP function, you have nothing to delete if MIN_STACK is 0 because each time you push a value MIN_STACK is incremented.MIN_STACK always points to the next free location. SO the data to be popped out is in (MIN_STACK-1)th position. So decrement the MIN_PATH and use it.

Take another approach, instead of joining first, then searching I chose to search first, then to join:

I finally got to find out the issue I was facing. It was indeed an Oracle issue after the upgrade to Oracle 12C. We talked to the Oracle Support and they responded back with the below: Queries involving hash joins were returning wrong results in cases where hash join would receive row sets as input and produced one row at a time as output.

Because of this, the query was becoming indeterministic and giving different counts at different instances. When the query was running in SQL Developer with where clause, SQL developer was providing a different output because of where clause, since it was changing the plan of execution but when I was pasting it in Excel and then filtering, it was showing different values since in this case, the query plan was different since there was no where clause.

Sorry if my question caused any kind of confusion. I just wanted to confirm if it was something else before asking DBA to reach out to the Oracle Support regarding this.

Linux already has a kernel process that is zeroing memory using idle cycles so it will have memory ready to hand to processes that request it.

Your loop may or may not zero different memory depending on the particular malloc implementation. If you really want to write a process like you describe, look into using sbrk directly to ensure you're cycling memory in and out of your process. I bet if you check you'll find every byte given to you by sbrk is already zero, though.

Ive made a web page with quite extensive JavaScript. Its runs fine in my browser and in my iPhone simulator. However on my iPhone 3G its very sluggish. My iPhone is pretty buggy though and often freezes for no reason so I dont know if its just my device or too much / bad code.

Other than using lots of devices (might be difficult to get my hands on), is there a good way to test this? Thanks

In fact, a class which inherits from an abstract class has to use ALL attributes and methods of it - it is nearly impossible to create a clean architecture with many levels of inheritance.

The main advantage of interfaces is the flexibility - you can implement much of them but do not have to change the internal structure of your class to implement them.

In most cases, it is best practice to use interfaces, except in some software patterns like compositum or strategy pattern.

But at the end it is your decision - you have to choose the type of inheritance you want in your project.

Interfaces help you to gain flexibility, abstract classes bring more cohesiveness to your architecture because they group classes that are similar together. --> you can reuse your code of the abstract classes in its subclasses

And I want to limit how much memory can be used by this program. I tried to set an initial and maximum size (from command-line), like follows :

It compiles in most cases (values of I, F), but if I declare test<8, 0>, I get the error:

My question is - is there some rules I'm violating here in terms of the specification of constexpr? Also, for the last error - mask type is unsigned - is this a compiler issue that it thinks I'm shifting a negative value or am I misreading the code?

This problem comes from easier problem which I managed to solve myself. So here is my original question.

In my data I have lots of categories, but i'm not interested in estimating coefficients for all of them, I just want to test the hypothesis, that there is no difference in categories. And calling summary on my object produces most information that I don't need for my report.

and got only the info that I needed, just in different formatting than summary(l1) produces.

What if I have some kind of a summary on an object and I want to extract just particular part of summary(object) how do I do that? For example, how do I get R to print only the line of call summary(l1)?

If you're looking to select only rows that are unique, in the sense that no other rows with the same name and parent exist, try:

I've tried bigmemory packages but still failed. Either crashed or reached the memory limits.

You are trying to access the variable which is cell array in MATLAB. Are you sure the data are stored consequently? What happens if you put double array into the structure?

You can see that each element of cell array occupy additional 60 bytes to the size of numbers.

Each of those ID's need to point to a specific list of information. Which is name, description and owner of course they link back to each ID in the master table.

My question is, should I make 4 separate tables or create one table since the information is the same in all the tables except one.

The procedureID will actually need to have an extra field for documentID to point to a specific document.

Is it possible and a good idea to make one table and add some inheritance, or is it better to make 4 separate tables?

I have a range of groups 1 to many (up to 12 rows - one row after an other per group) the initial part of the string as repeated I do not know how time they are repeated but ever time they are I need extract the relevant data which is everything after the repeated string. Now not all 12 row are in the group sometimes there are 11 or less but they are no blank rows in the group of data so what I do is once I find my header row I call a subroutine to go through the block of data and do my extraction, but when I get back and use the .findnext(v) it will not go to the next header

When I call this1 what I am doing is selecting another range because I do not know if my data is in the correct order I use another selection

when this Sub end my original selection is gone (it was column A:A), and my .findnext(v) gives me the last row of the previous group not the first row of the next group if one exists

I load some objects using the ctm binary loader in Threejs r69. This returns Mesh objects using a BufferGeometry internally. I need to remove from the scene then delete one of these Meshes, including their material/texture/geometry. According to examples and google, I should use:

This removes the object from the scene, but the screen goes black for a second, and I've got a GL error :

Looks like the above sequence (ran in my render() operation, just before drawing the scene) did not clean everything, or at least I still have references to non existing VBOs somewhere.

I've spent quite some time debugging the problem and came to the conclusion that this happens only when using an orthographic camera with a Sprite and a Perspective camera, in 2 differents scenes.

Basically, I draw a flat background using a Sprite and a dedicated scene, then my 3D scene with Meshes. If I delete a mesh from the 3D scene, then the drawing of the flat background fails. I can't figure out why. Looks like there's a side effect of deleting a Mesh on Sprites, even if attached to different scenes. If I comment the background drawing, then the deletion of my mesh works perfectly.

I insert below a reproduction of the problem using the standard threejs distribution. Wait about 5 seconds and you should see some GL errors on the jaavscript console.

Also what is the scope of your ClearAllIntervals() function? Is it possible that a new instance is getting created that doesn't remember the previous value of LastCleared?

Note that I haven't been able to find anything that documents that setInterval returns sequential numbers, as you seem to think it does. However, since setInterval doesn't "belong" to anybody, you can't override it to capture those interval id's.

Finally, I think AS3 in the later versions of the player has functionality to release loaded movies from memory, and it certainly has sand boxing that prevents loaded MC's from attaching themselves to anything in the loading MC.

I am having an issue with a playbook app I am working on. This is the first one i've done using Flex Burrito Hero, and on the simulator I noticed that the app fails to minimize gracefully (when multi-tasking etc).

Here is might suggestion, if not suitable please ignore it: use a self hosted service as @driis mentioned. That is your best option for your scenario. The about hosting an HTML page inside your WCF service...yes it is possible but this is not a simple solution. To summarize in one sentence, you have to create your custom message formater and bypass the default one provided by WCF. You would create an HtmlBehavior which must inherit from WebHttpBehavior, HtmlBehaviorExtension which must inherit from BehaviorExtensionElement and finally a HtmlFormater which would implement IDispatchMessageFormatter. On the following link you will find a great article about custom formatters: http://blogs.msdn.com/b/carlosfigueira/archive/2011/05/03/wcf-extensibility-message-formatters.aspx

First of all you should use table to store the values you have in your IN list and then join against that. If this is transient data, you could use temporary table.

Above statement creates the temporary table, inserts data into it and also removes all the duplicates.

I'd also suggest that you match types in your temporary table and columns you JOIN against, e.g. if kdt_goods_id is INT then yourid in your temporary table should be INT.

In actionDelete I have write query for get fk from all table and create activeDataProvider.and write a foreach loop for geting one by one element.

I'm making an app where a user would be able to add a button to the screen or remove it (I don't have those options implemented yet). So, for now I'm manually populating it with a for() loop and manually removing one of the buttons. My problem is that after the button has been removed (the removal action in the main()), there's just a blank spot. I want to be able to repaint the screen after I remove one of those buttons. In this example, index 2 (block #3) has been removed, leaving an empty space, where it was before... and I have no idea how to repaint it. I've tried validating or repainting from different places in the program with no success.

Here's the code (P.S. I'm sure my code is not the most efficient way to accomplish what I'm trying to and I'm using setLayout(null), which is not a preferred method, but for now I'm just trying to learn certain things and then expand on that to better myself and my code):

This works, but I don't need to check for 'Null' - I need to check for '.blank?' - because there are cases of non-nulls which are 'blank' in the DB, which I need to include. I can use '.blank?' in my class-defs (and do - and they work there), but I cannot use this in this current context.

I have not been able to find a syntax (of the non-depreciated variety) which will work for this. Thanks.

tag including html tags and store it in a variable

Consider the following stripped down part of some html code:

<section id ="test" contenteditable="true" ... > <h3> This is a header </h3> <p> Some stuff in here </p> <p> Some more stuff here </p> </section>

How do I get the <h3> and <p> elements from the section and store it in a variable?

E.g.

var result = "<h3> This is a header </h3> <p> Some stuff in here </p> <p> Some more stuff here </p>"

Also is it possible to get linebreaks etc as well?

I've tried using jquery .val() and JS document.getElementByID(..), but they both return the section element altogether.

The POSIX description of fdopendir() says:

Upon calling closedir() the file descriptor shall be closed.

So the descriptor is likely to be closed by the time you call openat().

And this is from a typical Linux man page for fdopendir():

After a successful call to fdopendir(), fd is used internally by the implementation, and should not otherwise be used by the application.

You friendship relationship here seems to be symmetrical.

In this case, you should insert the friends' ids in strict order: say, least id first, greatest id second.

This will make one record per friendship, not depending on who befriended whom.

Use this query:

SELECT 1 FROM users_friends WHERE (user_id, friend_id) = (LEAST($user_id, $SESSION['user_id']), GREATEST($SESSION['user_id'], $user_id))

to check the friendship status, and this one:

INSERT INTO users_friends (user_id, friend_id) VALUES (LEAST($user_id, $SESSION['user_id']), GREATEST($SESSION['user_id'], $user_id))

to insert a new record.

Instead of mapping the result to a POJO, I would suggest creating entities for both classes and mapping them with the one to one annotation JPA provides:

@Entity public class User{ @Id private long id; @OneToOne @JoinColumn(name="GROUP_ID") private Group group; ... } @Entity public class Group{ @Id private long id; ... }

Update to reflect updated question: You could then use e.g. the Criteria-API (or named queries), to query these entities:

CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder(); CriteriaQuery criteriaQuery = criteriaBuilder.createQuery(); Root user = criteriaQuery.from(User.class); criteriaQuery.where(criteriaBuilder.equal(user.get("id"), criteriaBuilder.parameter(Long.class, "id"))); Query query = entityManager.createQuery(criteriaQuery); query.setParameter("id", id); User result = (User)query.getSingleResult();

8092026 0 Eventbus event order

Morning,

I'm using the SimpleEvent bus to send data from my centralized data reviver to the Widgets. This works really fine, I get one set of new Data form the server, the success method of the RPC call puts it on the Eventbus, each widget looks if the data is for it, if yes it 'displays' it, if not, it does nothing.There is only one data set per request and the widgets don't depend on other data being already sent.

Now I have a Tree widget. The child nodes of the Tree are created throw this data sets too, and this child nodes register itself to the Eventbus to revive the data for their child nodes. The data shall be received in on rush (for performance reasons obv), so I will get multiple data sets which are put on the Eventbus at the 'same time' (in a for loop). I only control the order in which they are put there (first the root, then the data for the first child......). How does the Eventbus now proceeds the events?

Does he wait till the first event is completed, so the first child of the tree already finished creation and register itself to the Eventbus, to revive the data to create it's child's.
Does he handle them simultaneous, so a widget isn't even registered to the Eventbus.
Does he mix up the order?!?!

Current solution approaches:

The best solution I can think of, is to only put new events on the Eventbus when the previous got completed. However I found a method which does so, or if it is the standard behavior of the Eventbus .
Fire a request processing finished event, when a event was processed by a widget. Yucks... this leads to a lot of additional code and causes big problems, when data is put on the Eventbus which doesn't belong to any widget....
Register a static variable which is set to true when the request got handled and the Eventbus waits this long till he puts the next request on the Eventbus (Quiet similar to two, but way worse coding style and the same problems)
All events are handled by the root tree element, which sends them upwards to the respective child's.

Which solution would you prefer and why?

Regards, Stefan

PS: my favorite answer would be that 1. is the standard behavior of the Eventbus^^ PPS: The solution should also be working on when introducing Webworkers.

40356674 0 WEB2PY: Displaying data from DB with JOIN but with some condition

I am having trouble with some logic.

Many Service Request can be assigned to a Technician
The table db.assigned is where all assigned service_requestare saved together with the Technician's ID
Now I want to display all data in service_request EXCEPT for the service_request that was not assigned to the current logged In Technician

How someone please tell me how to make this work ?

What I have is this, I get all service request that has been assigned to the current logged in Technician, but does not get all the other service request that has not yet been assigned.

query=db.service_request.id==db.assigns.sr_id query2=db.assigns.technician==user_id query4=((query)&(query2)) get_assigned=db(query4).select(orderby=~db.service_request.date_time)

While Hackaholic's solution is excellent (and very functional-programming), here's an alternative using list comprehensions.

The key ingredient is zip(a,b,c), which returns a sequence of tuples containing the ith elements of a, b, c. As Joran Beasley mentions, your code will work just by adding zip:

d = [] for i,j,k in zip(a,b,c): d.append(i+j+k)

From here it's pretty easy to get to the list comprehension version:

d = [i+j+k for i,j,k in zip(a,b,c)]

And in fact you don't even need to unpack the tuple as i, j, k, instead you can sum the tuple directly:

d = [sum(tup) for tup in zip(a,b,c)]

You can do this with the CSS sibling selector ~, with the caveat that your hover element must come before the elements you want to style in the markup. You can display them in any order you like, though.

Demo:

CSS:

#one:hover ~ #three, #six:hover ~ #four { background-color: black; color: white; } #four { margin-left: -35px; } #six { left: 80px; position: relative; } .box { cursor: pointer; display: inline-block; height: 30px; line-height: 30px; margin: 5px; outline: 1px solid black; text-align: center; width: 30px; }

HTML:

<p>Hover over 1 and 3 gets styled.</p> <div id="one" class="box">1</div><!-- --><div id="two" class="box">2</div><!-- --><div id="three" class="box">3</div> <!-- this works because 4 is after 6 in the markup, despite its display position --> <p>Hover over 6 and 4 gets styled.</p> <div id="six" class="box">6</div><!-- --><div id="four" class="box">4</div><!-- --><div id="five" class="box">5</div>

14444503 1 Gmail IMAP is not returning uids

I am connecting to my gmail account via IMAP to sync some of my emails and parse them. Sometimes I need to download again some emails because I did some kind of fix and now gmail is not returning me the uids of those emails in any way, here is some code to explain myself better:

typ, data = self.connection.uid('search', None, '(SINCE 14-Dec-2012 BEFORE 20-Dec-2012)') 17:05.55 > HJBM3 UID SEARCH (SINCE 14-Dec-2012 BEFORE 20-Dec-2012) 17:05.69 < * SEARCH 17:05.69 < HJBM3 OK SEARCH completed (Success) ('OK', [''])

I have a good bunch of emails on those dates including the ones I want to parse and it doesn't return anything, depending on the date it does return some uids so is not completely broken.

I decided to try if thunderbird synced correctly those emails and it got them no problem.

I am using the python 2.6 imaplib (version 2.58)

I don't see any crashes , just no logs. The compiles fine. I am new to C, can someone let me know what am I missing here. The main idea is to access a global variable from my function. How do I do it?

Your syntax are correct but there is some problem with CSS overriding you can use !important to you class attribute

example :

<script> $(function(){ $(".breadcrumb a:first").addClass("itemhover"); }); </script> .itemhover{ color : red !important; }

"aPosition" is not used in the shader code so the GLSL-compiler has optimized away the variable. Try using it in the gl_Position assignment and you will notice that it works.

gl_Position = uMVPMatrix * uTMatrix * aPosition;

Mike from Fabric and Crashlytics here.

As you saw, Crashlytics by default includes Answers. If you don't want Answers enabled on your app, then you want to invoke CrashlyticsCore() when building your app instead of Crashlytics.

For example, have these as your imports:

import com.crashlytics.android.Crashlytics; import com.crashlytics.android.core.CrashlyticsCore; import io.fabric.sdk.android.Fabric;

Then when you initialize Fabric, use:

Fabric.with(this, new Crashlytics.Builder().core(new CrashlyticsCore.Builder().build()).build());

and that will initialize only the crash reporting side of things.

1931770 0 If I'm not going to be saving data into an SQL database, where should I be saving it?

I'm making an encyclopedia program of sorts similar to RAWR for World of Warcraft. I'm not going to be saving data de an SQL database, but I've been conditioned so hard to always do this when I'm sure there are alternatives for these lighter case uses.

For example, my program will have no creation of new data via user input, nor deletion of data via user input. Just a program that will display information that I code into it. Nothing more, nothing less.

Where should I save these things? By save I mean, store them for deployment when I release the program.

I'm mostly going to be saving just string variables and some videos/animation (see my other question)

Thanks for the help SO. As always, you guys rock!

Well the algorithm is as follows:

Let, P(N) denote the number of trees possible with N nodes. Let the indexes of the nodes be 1,2,3,...

Now, lets pick the root of the tree. Any of the given N nodes can be the root. Say node i has been picked as root. Then, all the elements to the left of i in the inorder sequence must be in the left sub-tree. Similarly, to the right.

So, total possibilities are: P(i-1)*P(N-i)

In the above expression i varies from 1 to N.

Hence we have,

P(N) = P(0)*P(N-1) + P(1)*P(N-2) + P(2)*P(N-3)....

The base cases will be:

P(0) = 1 P(1) = 1

Thus this can be solved by using Dynamic Programming.

Using Javascript and jQuery you could refresh the image at a given rate. When the image is loaded by browser you call reloadImage() which waits 100ms and then changes the source attribute for the image to a unique path, which prevents loading the image from browser cache memory.

HTML

<img id="myImage" src="filename.jpg" onload="reloadImage()"/>

Javascript

function reloadImage(){ setTimeout(function(){ $("#myImage").attr("src",'filename.jpg? + Math.random()) }, 100); }

This is seen when the orientation of the device is changed from portrait to landscape from the logcat logs. Also this issue has been seen on devices with Android 4.0.3 version. So wanted to check if it is a known issue with 4.0.3? Not sure from the code how to debug this issue as the stack trace is entirely of Android platform with no involvement of App code.

28871154 0 WSO2 Agent "Cannot proceed the authentication" but website works fine

I've gotten WSO2 working on the server. I can login through the management console and EMM, publisher, and store are all working. I can create a new user through the EMM dashboard, and the email is sent correctly. So everything is fine while using the website.

I'm using the sample APK that comes with WSO2 to do some development, but every time I try to register the app pops up "Authentication Failed - Cannot proceed the authentication. Please contact an administrator." And there is no output in the console when this happens.

If I put in the incorrect credentials I get a separate error, "Authentication Failed - Incorrect login information. Please try again." So I know my credentials are correct.

What does this mean? Is there another place to find more detailed logs?

you need to check if you are posting all the "posting fields".. some sites use security tokens or sessions ids to prevent bots from logging on their sites. anyway, you need to install Live HTTP headers firefox extension. open it and try to login manually, then see whats being posted actually when you press login button. after you get the values. add then to the first function and test again.

Its easiest to start with a black and white image (I used .png) 4 bytes are allocated to each pixel, the data of which you can get by using CgContextRef and CgContextDrawImage (I used the CGBitmapContextCreate method to populate an array of pixel data as well as create a black and white image from the edited data array. I averaged the rgb values for each pixel and then changed all pixel values to black or white (alpha == 255) depending on the average of rgb's.

Then you need to package every 8 pixels into 1 print byte (thus for a pixel of 4 bytes, look at a set of 32 bytes in the data array and set the binary values of the print byte on or off depending on whether a pixel is black (add pow(2, 7 - (position of pixel in 8 pixel sequence) ) or white (do nothing).

I converted a .png image to black and white .png and then to binary and printed the values on my screen. Try to keep the width of your .png in multiples of 8 or you'll have trouble (since you need to convert 8 bytes into 1 byte.

To join an array of strings into a single string by a separator (character which would be a string), you could use this method of NSArray class:

NSArray* array = @[@"iPhone", @"iPad", @"iPod"]; NSString* query = [array componentsJoinedByString:@","];

By using this method, you won't need to drop the last extra comma (or whatever) because it won't add it to the final string.

As an alternative, you can use flatten with len:

from compiler.ast import flatten my_list = [[1,2,3],[3,5,[2,3]], [[3,2],[5,[4]]]] len(flatten(my_list)) 11

This can be done with the collection method "find" as you did, but the selector must be a hash.

 col = db.collection(main) record = col.find({:property => value})

Since they are inline, use white-space:nowrap to prevent the list items from appearing on a new line.

Updated Example

.drop_menu { white-space:nowrap; } .drop_menu > li { white-space:normal; }

Since you don't want this to occur on the children li elements, set the white-space property value to normal.

You can use the dictionary returned by a call to globals():

input_name = raw_input("Enter variable name:") # User enters "orange" globals()[input_name] = 4 print(orange)

If you don't want it defined as a global variable, you can use locals():

input_name = raw_input("Enter variable name:") # User enters "orange" locals()[input_name] = 4 print(orange)

BTW, Microsoft no longer recommends that you derive from ApplicationException. Derive directly from Exception, instead.

Also, in your logging, be certain to log the entire exception. Use ex.ToString(), not ex.Message, etc. This will guarantee you see everything the exception class wants you to see, including all inner exceptions.

23915835 1 Transition Matrix in Dataframe Not Passing the Value

I am trying to implement transition matrix.

Both data and transition matrix are in DataFrames using Pandas

states_mat = pd.DataFrame(None, index=range(0,24), columns=range(0,24)) def states_update(data): states_vec = data['hr'] # Do nothing if there is no sequence if len(states_vec) < 2: return for i in xrange(1, len(states_vec)): prev = states_vec[i-1] curr = states_vec[i] states_mat[curr][prev] += 1

Data are in int64 type

It is not updating +1 count as I wanted. I believe it is some kind of type issue, but not sure how to force the type. I am using DataFrame for my data as I want to use group function to split the data and apply the above function. Any suggestions?

No, you cannot use a regex as a case statement in C. In fact, C has no built-in support for any kind of regular expressions at all^*. However, you can achieve the same result in terms of speed if you "expand" your regular expressions with fall-through:

switch (ch) { case '"'; case ';': case ',': case '(': case ')': case '{': case '}': case ' ': printf("\nSEPARATOR: %c found\n", ch); ch =fgetc(fin); break; case '_': case 'a': case 'b': ... // The other 24 letters go here case 'A': case 'B': ... // Same thing for uppercase letters case 'Z': printf("\nIDENTIFIER: "); ... }

Unfortunately, this would result in much longer code. You can convert it to a lookup table, though, which would be less readable, but run roughly as fast:

enum { OTHER , ID_START , DIGIT , SEPARATOR }; int map_char(unsigned char c) { static int *lookup_ptr = NULL; static int lookup[256]; if (lookup_ptr == NULL) { for (int i = 0 ; i != 256 ; i++) { if (i=='"; || i==';' || i==',' || ...) { lookup[i] = SEPARATOR; } else if (i=='_' || isalpha(i)) { lookup[i] = ID_START; } else if (isdigit(i)) { lookup[i] = DIGIT; } else { lookup[i] = OTHER; } } lookup_ptr = lookup; } return lookup_ptr[c]; }

Now you can use the function as follows:

switch (map_char(ch)) { case SEPARATOR: ... break; case ID_START: ... break; case DIGIT: ... break; case OTHER: ... break; }

^* Square bracket syntax of scanf functions only looks like regex, but it is not.

I just realized that, you are not floating the other element, this is causing it to shift down, you should use float: left; or right as it's a div so it will take up entire horizontal space, and hence it is pushed down.

Demo

.one, .two{ width: 300px; height: 450px; float:left; /* Float both elements */ background: #f00; }

Alternative

You should use display: inline-block; and white-space: nowrap; to prevent the wrapping of the elements

Demo

This will gave you the same effect, the only thing is 4px white space, you can simply use

.two { margin-left: -4px; }

the above will fix the white space issue for you

what I'd advice you would be to first remove all unnecessary data from the line, so you get exactly what you're looking for:

addr = [ x for x in line.split(" ") if x ][2]

and then printout that value along with the values in your list:

for target in mac_addr: print("'{}' vs '{}' -> {}".format(addr, target, addr == target))

so you can check how they differ.

In the end:

with open('arp_table_output.txt','r+') as myArps: for line in myArps: # select *ONLY* the lines that contain the IP and MAC information in the input file if "Dynamic" in line: # here we extract the IP and the MAC from the line (python3 syntax) ip, _, mac, *_ = [ x for x in line.split(" ") if x ] # if you prefer python2: use `x, _, y, _, _, _ = …` # Test to printout what works and what does not. If none pass, the "in" test below will fail. for target in mac_addr: print("'{}' vs '{}' -> {}".format(mac, target, mac == target)) if mac in mac_addr: ipaddr.append(ip)

This seems to be overcomplicating things somewhat: typically you would store an object's world position and orientation separately from its set of own local coordinates. Rotating the object is done in model space and therefore the position is unchanged. The world position of each coordinate is the same whether you do a rotation or not - add the world position to the local position to translate the local coordinates to world space.

Any rotation occurs around a specific origin, and the typical sin/cos formula presumes (0,0) is your origin. If the coordinate system in use doesn't currently have (0,0) as the origin, you must translate it to one that does, perform the rotation, then transform back. Usually model space is defined so that (0,0) is the origin for the model, making this step trivial.

There are certainly many options for this, but one that is very easy to implement and meets your criteria is an Asynchronous Web Service call.

This does not require you to start a worker thread (the Framework will do that behind the scenes). Rather than use one of the options outlined in that link to fetch the result, simply ignore the result since it is meaningless to the calling app.

The answer provided by @patricus above is absolutely correct, however, if like me you're looking to also benefit from casting out from JSON-encoded strings inside a pivot table then read on.

The Problem

I believe that there's a bug in Laravel at this stage. The problem is that when you instantiate a pivot model, it uses the native Illuminate-Model setAttributes method to "copy" the values of the pivot record table over to the pivot model.

This is fine for most attributes, but gets sticky when it sees the $casts array contains a JSON-style cast - it actually double-encodes the data.

A Solution

The way I overcame this is as follows:

1. Set up your own Pivot base class from which to extend your pivot subclasses (more on this in a bit)

2. In your new Pivot base class, redefine the setAttribute method, commenting out the lines that handle JSON-castable attributes

class MyPivot extends Pivot { public function setAttribute($key, $value) { if ($this->hasSetMutator($key)) { $method = 'set'.studly_case($key).'Attribute'; return $this->{$method}($value); } elseif (in_array($key, $this->getDates()) && $value) { $value = $this->fromDateTime($value); } /* if ($this->isJsonCastable($key)) { $value = json_encode($value); } */ $this->attributes[$key] = $value; } }

This highlights the removal of the isJsonCastable method call, which will return true for any attributes you have casted as json, array, object or collection in your whizzy pivot subclasses.

3. Create your pivot subclasses using some sort of useful naming convention (I do {PivotTable}Pivot e.g. FeatureProductPivot)

4. In your base model class, change/create your newPivot method override to something a little more useful

Mine looks like this:

public function newPivot(Model $parent, array $attributes, $table, $exists) { $class = 'App\Models\\' . studly_case($table) . 'Pivot'; if ( class_exists( $class ) ) { return new $class($parent, $attributes, $table, $exists); } else { return parent::newPivot($parent, $attributes, $table, $exists); } }

Then just make sure you Models extend from your base model and you create your pivot-table "models" to suit your naming convention and voilà you will have working JSON casts on pivot table columns on the way out of the DB!

NB: This hasn't been thoroughly tested and may have problems saving back to the DB.

11960453 0 What might I be doing wrong to get "Error: s > 0 is not TRUE" for a nlmer model?

I am attempting to learn lme4, and I'll admit up front that my statistical academic training was in traditional ANOVA designs at the home of SAS (NC State) over 20 years ago. I now have about 4-5 years of experience with R, but mostly with traditional general linear models with all factors treated as fixed effects.

I now would like to estimate the parameters for a von Bertalanffy growth model for an experiment with fresh-water mussels. Shell length was measured once per year for 4 years on known individuals (ID), so this is a repeated measures design. Ultimately I would like to add a main treatment factor and a split-plot factor. But, at the moment I can't get the simplified model to run. The R code that I'm using is:

VBGF <- function(Linf, k, age, age.0) { Linf * (1-exp(-k*((age-age.0)))) } VBGF <- deriv(L ~ VBGF, namevec=c("Lin", "k", "age.0"), function.arg=VBGF) mod1 <- nlmer(L ~ VBGF(Linf,k,AGE,age.0) ~ (Linf+k+age.0|ID), mussels, start=c(50,0.1,-11), verbose=TRUE)

I get the following error, and I have been completely unsuccessful in finding a reference to what it means.

Error: s > 0 is not TRUE

It's probably something simple that I'm overlooking, so I apologize for my ignorance in advance.

You are passing the values through intent correctly. I think you are getting problems while getting the passed values. Try this and this works for me.

You have to use a bundle for getting the values.

Intent intent = new Intent(); Bundle b = intent.getExtras(); int addTaskID = b.getInt("AddTask_Id, 0);

McDowell is right, but note that you can get rid of prefix and start mode checks in your loop if you make them part of the WMI query:

SELECT * FROM Win32_Service WHERE Name LIKE 'TTTT%' AND StartMode = 'Manual'

Using this query, your script could look like this:

var strComputer = "."; var oWMI = GetObject("winmgmts://" + strComputer + "/root/CIMV2"); var colServices = oWMI.ExecQuery("SELECT * FROM Win32_Service WHERE Name LIKE 'TTTT%' AND StartMode = 'Manual'"); var enumServices = new Enumerator(colServices); for(; !enumServices.atEnd(); enumServices.moveNext()) { var oService = enumServices.item(); WScript.Echo(oService.Name); }

The way your code looks like now, you shouldn't get a warning since myclass and myClassList have the same lifetime. However, if myClassList outlives myclass, you need to dynamically allocate MyClass:

vector<MyClass*> myClassList; { MyClass* myclass = new MyClass; myClassList.push_back(myclass); }

If the following is closer to what you actually have:

vector<MyClass*> myClassList; { MyClass myclass; myClassList.push_back(&myclass); }

then myclass is destroyed at the closing }, and myClassList will contain a pointer to released memory.

Also, is MyClass polymorphic? Do you really need to store pointers in the vector?

They are quite different in purpose.

OpenAL is a low level, cross-platform API for playing and controlling sounds.

AudioSession, as the documentation puts it, is a C interface for managing an application’s audio behavior in the context of other applications. You may want to take a look at AVAudioSession which is a convenient Objective-C alternative to AudioSession.

You would typically use Audio Sessions for getting sound hardware information, determining if other applications are playing sounds, specifying what happens to those sounds when your application also tries to play sounds, etc.

Audio Sessions are all about managing the environment in which your application plays sounds. Even sounds played using OpenAL are subject to the rules imposed by your application's audio session.

You should really check out the docs. There is a lot to cover.

30001768 0 Angular set ng-checked for specific child onclick

If someone clicks on the link the child input element should get the attribute ng-checked = "true" and if he clicks again it should be set false.

I already managed to implement this behaviour but the problem is that i have multiple checkbox probably around 20 and i do not want to set a unique variable for all of those

<a href="" ng-click="setSelect()"> <div class="checkbox"> <label> <input type="checkbox" ng-model="someModel" ng-checked= "selectStatus"> text </label> </div> </a>

and the according setSelect method

$scope.toggleSelect = true; $scope.setSelect = function () { if ($scope.toggleSelect){ $scope.selectStatus = true; $scope.toggleSelect = false; } else { $scope.selectStatus = false; $scope.toggleSelect = true; } };

is it possible to do this without jquery and in an easy way?

As others already wrote, I believe this behavior is caused by the fact that the dialog starts its own event loop.

The images of your charts helped a lot in understanding what you trying to do. Using ddply with summarize from the plyr package does the same calculation as tapply but returns the result in a data frame that ggplot can use directly. Given that different data is used in the two examples, the code below seems to reproduce your chart in R:

 library(plyr) df3 <- ddply(df2,.(sex, smoker), summarize, BMI_mean=mean(BMI)) ggplot(df3,aes(as.numeric(smoker), BMI_mean, color=sex)) + geom_line() + scale_x_discrete("Current Sig Smoker Y/N", labels=levels(df3$smoker)) + labs(y="Mean Body Mass Index (kg/(M*M)", color="SEX")

C++ friendship works the other way: if GameComponent declares Position as a friend it means that Position has access to all the private methods of the GameCompenent. What you need is exactly the opposite: call Position private methods from GameComponent

So if Position::displayPositions() is the private method of the Position class that you want to access from GameComponent then you can declare GameComponent as a friend of Position:

class Position { friend class GameComponent; ... };

I'm developing an application which uses WebSQL DB to store data and then retrieve it. The UI is powered by jQuery Mobile, and when I successfully get back the data from the DB, I put it in a listview.

When I do that, I get the data, but with no styling at all. Just plain web browser rendering.

To refresh the layout, I looked on jQuery Mobile Docs that I need to use $('#list').listview('refresh');

Now I tried several implementations of this and always failed. I'm asking, which event should the refresh statement go in. On my page load I load the Data and put it in the DOM.

The problem in your code is that, on the first button click, you are adding the value to the ArrayList, of which the state is not saved during the post back. Which means, on the Button2_Click event the array list will always be empty.

Change your value property something like this. Or Save the Arraylist value to the session in the DataList1_ItemCommand event itself

ArrayList value { get { ArrayList values = null; if(ViewState["selectedValues"] != null) values = (ArrayList)ViewState["selectedValues"]; else { values = new ArrayList(); ViewState["selectedValues"] = values; } return values; } }

15835405 0 Oracle representing hierarchy of data combinations

I'm having an Oracle volume of data issue, which I think is being caused by a data representation problem. I have a hierarchy made from seven different lists, and need to store all the unique potential combinations of these elements. I need to store all the potential combinations, because I need to store additional information along with them.

Historically, we've been managing four lists, which came to a few thousand combinations. This was fine, but requirements have changed as they are wont to do, and now we are running seven lists. In my real environment, the lists store between 20 and 200 items. The total number of combinations for this now, incredibly, is about 350 billion.

As an example of what we're trying to represent with this, you could have a selection of lists like:

Colours:Red, Green, Blue

Shapes: Circle, Square, Triangle

Flavours: Peach, Banana, Raspberry

These would be stored as separate tables in Oracle like COLOURS, SHAPES, FLAVOURS, etc, and what we'd be doing is multiplying them all together (via a Cartesian join) to get an exploded table: This is what we're storing in Oracle at the moment.

COLOUR SHAPE FLAVOUR DATA_1 DATA_2 Red Circle Peach -- these hold additional information Red Circle Banana Red Circle Raspberry Red Square Peach Red Square Banana ...

and so on.

We've found we can't store billions of records within an Oracle table and have any operation performed upon them in a timely fashion. I've tried to think of different ways to store this information but my brain keeps jamming up on the number of combinations. Is there anything I can do to store the records differently? Bearing in mind they're all unique combinations, and we need to store data along with them.

Thanks for any help!

16093122 0 PHP Recursive Array Intersect Key Tripping over string value

I'm currently receiving an error PHP Catchable fatal error: Argument 2 passed to NUI::recArrInterKey() must be an array, string given when trying to recursively intersect a multidimensional array (grey/white list).

It seems to be tripping on the $foo['contact']['im']['provider'] section for some reason that I can't figure out?

Here's an example whitelist array ($array2) that I am using

Array ( [location] => false [network_name] => false [interests] => false [last_name] => false [url] => false [significant_other] => false [network_domains] => false [contact] => Array ( [im] => Array ( [provider] => false ) [email_addresses] => false ) )

And the method

/** * Recursive array intersect key */ private static function recArrInterKey(array $array1, array $array2) { $array1 = array_intersect_key($array1, $array2); foreach ($array1 as $key => &$value) { if (is_array($value)) { $value = self::recArrInterKey($value, $array2[$key]); } } return $array1; }

lets say that this is $array1

Array ( [location] => Seattle [occupation] => Developer [network_name] => foo.network [network_region] => foo.region [interests] => coding [last_name] => daniel [url] => false [id] => 4665228 [significant_other] => some girl [network_domains] => false [contact] => Array ( [im] => Array ( [provider] => aol ) [phone] => Array ( [provider] => at&t ) [email_addresses] => dont@mail.me ) )

I am expecting this as a return

Array ( [location] => Seattle [occupation] => Developer [network_name] => foo.network [interests] => coding [last_name] => daniel [url] => false [significant_other] => some girl [network_domains] => false [contact] => Array ( [im] => Array ( [provider] => aol ) [email_addresses] => dont@mail.me ) )

You have 17GB of RAM available for about 20GB of data plus 4GB of indexes (and that's just on this DB - I don't know if there is more in your system, but mongostat says you have total datafile size of about 28GB).

If you are querying over your entire dataset, wouldn't you expect that eventually new data records being read can no longer fit into RAM without displaying some of the previously read (and loaded into RAM) records? That's what you're seeing with page faulting.

It's not data storage that you are concerned about, it's data being used or queries or accessed. If it all can't stay in RAM then it will get swapped out and then will need to be swapped back in when accessed again.

global objects which inherit from Object,

That's a wrong assumption, global objects are host objects and they can inherit from whatever they want or not inherit anything at all. The code for example doesn't work in IE10.

The particular toString method stored on Object.prototype is the only one that returns the internal class name for sure. Functions, arrays, numbers etc do not inherit the Object.prototype toString method but define their own toString method, as in Number.prototype.toString !== Object.prototype.toString.

What are some advantages/disadvantages to using either approach?

Using sequential numbers

Advantages: Easy to implement

Disadvantages: Possible vector for attack. See this video for a high-level overview.

Using random numbers

Advantages: Solves the problems outlined in the video re: sequential record attacks

Disadvantages: Since there's only 10 bits of entropy, ID's would have to be much longer if your app grows.

Base 64 (use this instead of hex)

Advantages: 64 bits of entropy means an ID 5 chars long would have 64^5 possible permutations. This allows for comparatively much shorter URLs. Use SecureRandom.urlsafe_base64 for this.

Disadvantages: None, really.

Is there a good industry standard or best practice for generating synthetic ids for concepts like users, groups, posts, etc..

To my knowledge, no. Anything sufficiently random and of sufficient length should be fine. Within your model, you'd want to check if an ID is taken first so you don't have duplicates, but outside of that there's little to worry about.

What's the best way in Ruby/Rails to generate each of these IDs? I know of SecureRandom.hex but that seems to generate a long hash.

Like I said above, I recommend using SecureRandom.urlsafe_base64

have you made sure that during MDM enrollment, the MDM payload (PayloadType = com.apple.mdm) you deliver has the correct Topic?

i.e. in your APN push cert that you've downloaded from apple.you'll see something like CN = com.apple.mgmt.external.[GUID]. This needs to be the same value delivered to your IOS device during MDM enrollment.

If APN does not give any error during the message upload, or the feedback service does not return the deviceID which indicates that the device is not available, it should mean that it will be delivered correctly to the device. The next phase is to determine if the IOS device is setup to listen to the APN message via this topic.

You can try connecting your device to XCode or IPCU, in the console logs, it will contain logs indicating if APN was able to successfully deliver this message using the agreed upon topic.

Here's also an article on troubleshootin APN http://developer.apple.com/library/ios/#technotes/tn2265/_index.html

there's a downloadable profile in the above article that you can load to your device for additional verbose logging.

3626662 0 Android, Google Analitics: how to implement page view tracking on "/quit" application exit?

I need to track my Android application exit as a page view. My application has several activities, but there is no hierarchy, so there is not an unique exit point.

My understanding is that "application exit" means another application is on top of mine, hiding it completely. So if my application is no more visible, there is an "application exit". Is my understanding correct?

So, how could I track this "application exit" with Google Analytics?

Looking forward for advice. Thank you.

Some browsers will add all attributes as named properties of the DOM element, others will only add standard attributes. In both cases you can get non–standard attributes using getAttribute, however such a scheme is not recommended.

It is common to use standard attributes and DOM properties and only use getAttribute where necessary as it is inconsistently implemented in different browsers.

Your definition of your status field is incorrect. CharFields require a "max_length" attribute that is a positive integer.

Change it to the following:

models.CharField(max_length=..., choices=STATUS_CHOICES)

PageHeap

To enable the heap verification ("PageHeap") you set the configuration you want using the GFlags utility, either using the GUI or passing it the approporiate command-line arguments (See GFlags and PageHeap). Either way, this setting it global for all binaries with the name you define.

Debugging

To run the program under the debugger each and every time it starts you'd probably want to use the Debugger setting under Image File Execution Options. You can set it too using GFlags. Tick the Debugger checkbox in the Image File tab (after specifying the EXE name and hitting tab) and enter the path to the debugger.

The way this mechanism works is that (somewhere) inside CreateProcess there's a test whether or not IFEO\Debugger is set for the program you're trying to run, and if it is set, whatever set in the Debugger value is executed **and it is passed the original command line*.

So if you set

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\foo.exe\Debugger

to be C:\Program Files (x86)\Windows Kits\10\Debuggers\x64\windbg.exe and then try to execute C:\Users\d_blk\Desktop\foo.exe -param 1 -param 2, Windows runs

C:\Program Files (x86)\Windows Kits\10\Debuggers\x64\windbg.exe C:\Users\d_blk\Desktop\foo.exe -param 1 -param 2

and WinDbg passes everything after foo.exe to the target program (as noted here).

So you see, there's no need to set the command-line arguments to the program you're debugging anywhere but wherever you're running it.

The only connection between PageHeap and IFEO\Debugger is that you can control both of them through the GFlags utility.

Caveats

Note all the usual caveats for using IFEO\Debugger. For example:

The caller gets from CreateProcess a handle to WinDbg, not the target process (and process ID, etc.).
Any information in a non-default STARTUPINFO argument applies to WinDbg, not the target process. Same for lpEnvironment I guess.

If that doesn't affect you great. If it does, an alternative might be adding an unhandled exception at the beginning of your program, and setting WinDbg as the post-mortem debugger (AeDebug)

You cannot do what you want (because you ruled out dynamic allocation), and your "solution" does not work in general, even if you avoid the problems with compiler-generated special member functions which others mentioned. One problem is that types not only have a size, but also an alignment. For example, your real class contains an int, however your replacement class contains only a char array. Now on most platforms, int has alignment 4 (i.e. an int must be located at a 4 byte boundary), while char has aligment 1 (it cannot have any other alignment without violating the standard). That is, as soon as you try to create an object with your replacement definition, you risk getting it misaligned, which in the best case will cause a massive slowdown, in the worst case a crash of your program (and in the absolutely worst case, it will work in your tests, but fail when actually used).

This appears to be a defect in the dotnet dnx tools but in my case I was able to work around the defect. I expect a fix will will be in place by RTM as this was an RC build of dot net core.

The Nuget.HttpSource constructor assigns the credentials as follows when the environment variable "http_proxy" is in the simple (non-username) format:

UriBuilder builder = new UriBuilder(environmentVariable); WebProxy proxy = new WebProxy(environmentVariable); if (string.IsNullOrEmpty(builder.UserName)) { proxy.Credentials = CredentialCache.DefaultCredentials; }

DefaultCredentials is set to an immutable set of empty Credentials:

SystemNetworkCredential.s_defaultCredential = new SystemNetworkCredential(); private SystemNetworkCredential() : base(string.Empty, string.Empty, string.Empty) {}

Since SetProxyOptions() checks the credential using:

if (credential != null) { if (string.IsNullOrEmpty(credential.UserName)) throw ...

And the UserName is Empty it will always throw an exception.

If instead it were to check using:

if (credential != null && !string.IsNullOrEmpty(credential.UserName)) // do cred work

Then all would be well. Null or default credentials (e.g. SystemDefaultCredentials which are immutably empty) would be treated as "no credentials".

Otherwise Microsoft could change the DNX tool to leave the credentials null instead of using the SystemDefaultCredentials. This is a simple case of the caller and callee disagreeing on the protocol for specifying a lack of credentials (null ref vs. ref with empty strings).

In my case the workaround I used was to fill in a bogus credential so that the dnx tool wouldn't throw. Luckily my proxy server didn't complain about the unwanted and invalid credential.

You should extends Canvas class.

Override OnDraw() Method and create point's zone for your image.

Point[][] points = new Point[5][5] Then lay it(use relation layout) to your screen.

Get zone where you touch it. if(points[i][j] == your Touch(get coordinates)){

I think what you may be seeing is:

http://servername.domain.com/virtualdirectoryname/applicationname

If you have named your virtual directory the same name as your application then I could see how that could confuse you. If you had no virtual directory and just your application at the root of the Default Web Site you'd be seeing:

http://servername.domain.com/applicationname

Is your virtual directory the same name as your application name? If so, that is why you see this.

206899 0 What's the best way to truncate a URL so that it fits within a layout

What is the best way to truncate a URL when displaying it within a web page? I don't mean a link but literally displaying the URL as a value to the user, assuming that the text might be in a container of fixed width and you don't want to wrap or run outside of the container?

Is it better to truncate from the end, favouring the early part of the url:

eg. http/really.long/urlthaticantf...ere.html

Or place the '...' in the middle to favour the start and end of the link as the most value in terms of giving context:

eg. http/really.long/ur...aticantfithere.html

Also what is a good rule of thumb when choosing how long to make the truncated url? Should you be pessimistic and pick a likely wide character such as capital 'M' and see how many of these fit in the layout? This tends to give really short URLs in general as most characters are much narrower than 'M'.

Or should you be optimistic and use a truncation that generally gives a good length but risk overrunning when the URL contains many large characters?

22690456 0 Can't check if more than 1 post data isset in the same if statement

I'm trying to validate data but I'm having trouble.

The problem is I am checking if certain post data is set. Problem is it's either always set or not, i think it's because I am trying to check for multiple things in an incorrect format in my if statement?

I think it's only this line that is incorrect but I am having some sort of mental block.

I understand it is probably something quite trivial but I can't think of a way to word it to find a solution via Google.

if ((!isset($_POST['first_name'])) || (!isset($_POST['contact_no'])) || (!isset($_POST['device'])) || (!isset($_POST['fault']))) { echo 'no Name, contact number, device or fault given.'; }

I know i could check in separate if's but I would really like to refresh how i check multiple items in the same statement..

After trying suggestions, without any luck, adding more information:

if (isset($_POST['posted']) == 'TRUE') { $error = array(); if( !isset($_POST['first_name']) ){ $error[] = 'no Name given.'; } elseif( !isset($_POST['contact_no']) ){ $error[] = 'no contact number given.'; } elseif( !isset($_POST['device']) ) { $error[] = 'no Device given.'; } elseif( !isset($_POST['fault']) ) { $error[] = 'no fault given.'; } if( count($error)!==0){ echo 'Error(s) occured:<br />'.implode('<br />', $errors); } else { $db->query("INSERT INTO repairs (r_oem, r_device, r_mod, r_reserve, r_price, r_s_date, r_e_date, r_notes, rc_fname, rc_lname, rc_email, rc_contactno, rc_return, rc_status, rc_status_2, rc_status_txt, rc_status_txt_2, booked_by, passcode) VALUES( '$make', '$device', '$model', '$fault', '$price', '$date', '$date2', '$notes', '$fname', '$lname', '$email', '$cno', '','$status', '', '', '', '$bookedby', '$pass')"); $get_id = $db->query("SELECT LAST_INSERT_ID()"); $print_id = $db->fetch_row($get_id); $last_r_id_insterted = $db->query("SELECT * FROM `repairs` ORDER BY `repairs`.`r_id` DESC LIMIT 1"); $plrid = $db->fetch_row($last_r_id_insterted); echo '<br />'; echo <<<EOF <script> alert("Successfully created record for {$fname} {$lname}\'s {$make} {$device} {$model}.

Your issue is not with Array, your question really involves escape sequences for special characters in strings. As the \ character is special, you need to first prepend it (escape it) with a leading backslash, like so.

"\\"

You should also re-read your link and the section on escape sequences.

You probably want to declare fields, and get the values of the parameters in the constructor, and save the parameters to the fields:

public static class TCP_Ping implements Runnable { // these are the fields: private final int a; private final String b; // this is the constructor, that takes parameters public TCP_Ping(final int a, final String b) { // here you save the parameters to the fields this.a = a; this.b = b; } // and here (or in any other method you create) you can use the fields: @Override public void run() { System.out.println("a: " + a); System.out.println("b: " + b); } }

Then you can create an instance of your class like this:

TCP_Ping ping = new TCP_Ping(5, "www.google.com");

is it as simple as sitting in branchB and doing:
git merge branchA 

Yes, git has power in its simplicity.

or do i need to do a:
git pull origin branchA 
What's the difference here?

The only difference here refers to using a remote repository. If you're pushing code to a remote, like Github, from another machine (or working with another person) then you would want to fetch any updates from there. If all changes are just on your local machine, then a pull will provide no new information.

Doesn't pull do an implicit merge?

Yes, it's shorthand for git fetch and then git merge

Does
git merge branchName 
do an implicit pull on the branchName?

Nope. Merge only uses your local branch. So, not to confuse you further, but your remotes have local "tracking branches" that you could merge like:

git merge remote/branchName

There is a simple method of serving a folder over HTTP with WEBrick.

def call(env) contents = File.open("index.html") { |f| f.read } return [200, {"Content-Type" => "text/html"}, [contents]] end

The Cortex M3 has excellent fault handling features that will make your life easier. On hitting a fault, it automatically stacks several registers like PC and LR, and fault status registers will tell you things like address of bus fault, etc.

You should implement a good fault handler (for example, the hard fault handler here: http://blog.frankvh.com/2011/12/07/cortex-m3-m4-hard-fault-handler/) to print out the stacked registers and debug fault status registers.

You should use the UART for printing, just write your own simple custom version of printf for use from your fault handler that doesn't depend on interrupts. Just write bytes directly to uart Tx data register and poll for byte completion.

Likewise, an @Consumes should do the same trick for input.

(Having said that, you should probably emphasize the payload more. Just having chars as input/output is an indicator that your resource design is flawed)

Hint: Since you are using C++, look up the hex I/O Manipulator:
http://en.cppreference.com/w/cpp/io/ios_base/fmtflags

If you want to use the C style I/O, look up the printf modifier, %x, as in "0x%02X ".

Edit 1:
To save in a variable, using C style functions:

char hex_buffer[256]; unsigned int i; for (i = 0; i < size; i++) { snprintf(hex_buffer, sizeof(hex_buffer), "%x ", buffer[i]); }

Using C++, lookup the std::ostringstream:

 std::ostring stream; for (unsigned int i = 0; i < size; ++i) { stream << hex << buffer[i] << " "; } std::string my_hex_text = stream.str();

Uninitialized memory allocated by new won't behave nice with strlen().

It'd be better if one wrote:

memset(szBuf, 0, MAX_MSG * sizeof *szBuf);

You could also skip sizeof *szBuf since it's guaranteed to be 1, but it doesn't hurt.

Short answer: You cannot: AFAIK, currently there is no way to do it from sqlalchemy directly.

Howerever, you can use sqlalchemy-migrate for this if you change your model frequently and have different versions rolled out to production. Else it might be an overkill and you may be better off generating the ALTER TABLE ... scripts manually.

6625258 0 how do I build a Facelets site at build-time?

I want to use Facelets to build a static HTML prototype. This prototype will be sent out to people who do not have a running web application server such as Tomcat. Is there some way to compile a Facelets site at build-time (using Ant etc) into a set of flat HTML files?

In the simplest case we have two facelets like this:

<!-- layoutFacelet.xhtml --> <ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets"> <ui:insert name="content" /> </ui:composition> <!-- implementationFacelet.xhtml --> <ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" template="layoutFacelet.xhtml"> <ui:define name="content"> HELLO WORLD </ui:define> </ui:composition>

The output would be a single html (e.g. "implementationFacelet.output.html") like:

In other words, Facelets is running at build-time rather than render-time, in order to produce static flat-file prototypes.

23202916 0 Characters not properly displayed in serial monitor in arduino

Can anyone tell me why the characters are not getting printed properly in the serial monitor of Arduino? I am pasting the arduino code.

#include <SoftwareSerial.h> #include <LiquidCrystal.h> // initialize the library with the numbers of the interface pins LiquidCrystal lcd(12,11,5,4,3,2); int bluetoothTx = 15; int bluetoothRx = 14; SoftwareSerial bluetooth(bluetoothTx, bluetoothRx); int incomingByte; void setup() { pinMode(53, OUTPUT); Serial.begin(9600); lcd.begin(16, 2); lcd.clear(); bluetooth.begin(115200); // The Bluetooth Mate defaults to 115200bps delay(320); // IMPORTANT DELAY! (Minimum ~276ms) bluetooth.print("$$$"); // Enter command mode delay(15); // IMPORTANT DELAY! (Minimum ~10ms) bluetooth.println("U,9600,N"); // Temporarily Change the baudrate to 9600, no parity bluetooth.begin(9600); // Start bluetooth serial at 9600 lcd.print("done setup"); } void loop() { lcd.clear(); Serial.print("in loop"); //Read from bluetooth and write to usb serial if(bluetooth.available()) { Serial.print("BT here"); char toSend = (char)bluetooth.read(); Serial.print(toSend); lcd.print(toSend); delay(3000); }delay(3000); }

Can anyone take a look into it. It does not print the character that I provide instead it prints something else like 'y' with 2 dots on top etc. Tried almost all the available solution.

13611882 0 HighchartsJS Click Event on iOS 6

After the release of iOS6, the Highchart bar graphs we've been using in our site stopped responding to click events on iOS devices. Although the graphs render correctly, the click function simply does not fire when clicking data points within.

Oddly, I discovered that the function does fire on click in iOS if it's attached to the mouseOut event, instead. I.E. If I define events: { mouseOut: function(){ //dosomething } } and then click the datapoint in the graph, iOS device will perform the function. (It is possible this is always the case with iOS device mouseOut, as there is no analogous touch event; the point, however, is that some events are firing in this context.)

I have created a very basic set of graphs in a flat HTML page to test the basic functionality of Highcharts in iOS 6, and that seems to work as expected for click events attached to data points.

I am happy to post the code (or a Fiddle link) with the specifics of the graph data, but I am more interested in knowing whether anyone else has seen a problem like this in iOS 6 with Highcharts JS.

Thanks so much for any insight you can offer. (As I said, the basic charts I created using the objects and data our site generates seem to work fine from a flat HTML page, so I don't think code would be terribly helpful in answering questions. But, I'm willing to post that code if someone thinks that would help them come to a conclusion.)

36835788 0 Webdesign: Wrapping table suppresses scrollbars in IE 11 and Firefox

We have to get a legacy web application to run in Internet Explorer 11 and Firefox. The application does not set any doctype and therefore sends both browsers into quirks mode.

We have a table that needs to be scrollable, which is embedded in a div with overflow: auto. This works on its own, but our web application embeds this div again in a table and wraps the table with another two divs. See the fiddle here:

https://jsfiddle.net/Tim_van_Beek/y7hsp1zp/3/

(Please use IE 11 or Firefox, the page does not work in Chrome at all.)

The wrapping table (the first -node in the HTML tree) seems to suppress the scrollbars. They reappear when one removes it. So while this structure does not have scrollbars (see fiddle above):

<div style="overflow: hidden;..."> <div ...> <table width="auto" height="auto" cellspacing="0" cellpadding="0"> <tbody> <tr> <td width="100%" height="100%" align="left" valign="top"> <div style="overflow: auto;"> ...table data to be scrolled

...this one does (remove the table, tbody, tr and td tags):

<div style="overflow: hidden;..."> <div ...> <div style="overflow: auto;"> ...table data to be scrolled

It would seem that one needs to format the table in a certain way to get it to display scrollbars again (or rather: not suppress the scrollbars of its child node), any suggestions?

We cannot simply remove the table from our application without compromising the rest of the layout, but we can add/modify css at will.

1906578 0 switch mod rewritten URL

We are using a mod rewritten URL within our PHP site, this is the rewrite rule we are using:

RewriteRule ^category/([^.]+)/([0-9]+)/([^.]+)/([0-9]+) categories.php?c_id=$2&filters=$3&_p=$4&area=category&areaname=$1

However, a user of a different system is switching to our setup and wants to 301 all their old pages to their new equivalents. So, for example, this URL:

http://domain.com/categories/clothing/5/1

becomes:

http://domain.com/category/clothing/5/0-0-0-0/1

Is it possible to do this in a single rewrite rule or rewrite match (or similar), my intial thought was something like this would work:

RewriteRule /categories/(.*)/(.*)/1 /category/$1/$2/0-0-0-0-0-0-0-0/1 [R=301,L]

it doesn't, any ideas?

Also tried this with RedirectMatch which also doesnt work:

RedirectMatch /categories/(.*)/(.*)/1 http://domain.com/category/$1/$2/0-0-0-0-0-0-0-0/1

Queue is an interface not a class. LinkedList is an implementation of Queue interface.

You can think it like this.

Animal a = new Cat() Animal b = new Dog() Animal c = new Cow()

a,b and c are all animals. But they are all different kind of animals.

There are other implementation of Queue interface like ArrayBlockingQueue and PriorityQueue. They all implement Queue interface but do things diffferently inside. http://docs.oracle.com/javase/7/docs/api/java/util/Queue.html http://docs.oracle.com/javase/7/docs/api/java/util/LinkedList.html

You can think it like this. Animal a = new Cat() Animal b = new Dog() Animal c = new Cow()

Easiest way I could see to do this was absolutely positioned 'before' pseudo-element with the gradient applied to it, and the opacity set to 0 when active. I've also added a toggle on the ul itself for the sake of ease.

Easiest to give you the jsfiddle:

https://jsfiddle.net/efreeman79/8oemm50L/1/

I've added this to the styles:

li:before { content: ''; display: block; position: absolute; left: 0; bottom: 0; height: 100%; width: 100%; opacity: 1; transition: all 0.35s ease; /* GRADIENT CSS CODE HERE */ } .active li:before { opacity: 0; } li.even:before { transform: rotate(180deg); }

and this for the sake of ease:

$('ul').toggleClass('active');

It needs some polish but it does the job. Basically when the ul is active, opacity on the gradient is set to 0, when the active class is removed, the gradient layer's opacity is animated back to 1.

Everything inside that if (isset($_FILES['picName'])and isset($_POST['submit'])) doesn't work because the superglobal $_FILES is probably not having a key named picName. To check this out, try var_dump-ing the $_FILES, like var_dump($_FILES);

By the output of the var_dump you'd get to know if there is any content inside $_FILES. And if it is populated, just see what the key name is and, access the file by using that key.

But if the array is empty, there may be some mis-configurations in PHP, or APACHE.

One possible fix would be setting file_uploads = On in the ini file for php.

Hope it helps!

One thing to consider is how many date calculations you are performing and where in the query your conversion is taking place. If you are searching a DB of 10 million records and you are converting a DateTime field into a Unix Timestamp inside of a WHERE clause for every single record and only ending up with 100 records in the query result it would be less efficient to use SQL to perform that conversion on 10 million records than it would be to use PHP to convert the DateTime object into a Timestamp on only the resulting 100 records.

Granted, only the result of 100 records would be converted anyway if you put the conversion in the select statement so it would be pretty much the same.

Catch-all email trappers aren't implemented in DNS to the best of my knowledge, they're configured at the email server level. So there's no shortcut for testing this other than checking for the validity of an email address.

Note that you don't have to actually send an email to test. Within, say, an SMTP session the RCPT TO command returns: 200 or 250 on success, 251 or 551 on forward, 252 cannot verify but will accept, 450 or 550 mailbox unavailable, 552 exceeded storage, 553 mailbox name not allowed. Upon determining whether/not the wildcard exists you'd send a QUIT.

Luca Bolognese has written a great series of Write Yourself a Scheme in 48 Hours in F# where he used FParsec for parsing. The full source code with detailed test cases are online here.

The most relevant post is 6th one where he talked about parsing a simple Lisp-like language. This language is closer to JavaScript than to C just so you know.

Current series on his blog is parsing lambda expressions in F# (using FParsec) which could be helpful for you too.

The SDF classes aren't designed to be "better" than the CF classes - they are largely an extension of the CF-supplied classes. In many cases they provides methods, properties, etc. that the full framework may have but that the CF omitted.

Obviously that's an over-simplification - for example the entire OpenNETCF.WindowsCE namespace is purely features that don't exist in the FFx or the CF, but as a general answer, that's how it works.

The SDF is not a replacement for the CF, it's an extension of it.

Why? You only care if something is listening if you want to connect to it. So, connect to it, and handle the error. "Don't test, use." This applies to any resource. The best way to test whether it is available is to try to use it.

6115324 0 Evasive cause inside InvocationTargetException

Executing a Java code I capture an InvocationTargetException. Using the printStackTrace method I get the following:

java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at Tester.main(Tester.java:180) Caused by: java.lang.NullPointerException at [...] (it doesn't really matters)

My code checks several programs written by other persons, so the cause shown by printStackTrace is varied. However, if I try to get just the internal cause using method getCause, the result is always a disgusting null!

Java 6 API says that, from release 1.4 in advance, getCause returns the cause exception provided during construction... should I assume that Method.invoke does not construct the exception properly, or am I losing something?

Thanks in advance

You're trying to access parts of a variable which don't exist. You may want to check before using them, if they exist.

That will work if Environment.NewLine is CR+LF, which it's likely to be on Windows. Of course it won't catch the situation where the string actually only contains line feeds, or only contains carriage returns. Perhaps you want:

StringBuilder sb = new StringBuilder(s).Replace("\r\n", "<br/>") .Replace("\n", "<br/>") .Replace("\r", "<br/>");

(Note that there's no point in using a verbatim string literal for "<br/>" as there's no backslash in the string, and it's a single line.)

You could instead output the images as a list of divs, or just divs, and then use CSS to show the images in two columns. Your layout should not be that hardwired.

<style> div.gallery { width: 650px; } div.gallery ul li { list-style: none; float: left; } div.image { height: 500px; width: 300px; } </style> <div class="gallery"> <ul> <li> <div class="image"> <span class="image_title">Some title</span><br/> <img src="foo.png"/> </div> </li> <li> <div class="image"> <span class="image_title">Another title</span><br/> <img src="bar.png"/> </div> </li> <li> <div class="image"> <span class="image_title">Another title</span><br/> <img src="foo.png"/> </div> </li> <li> <div class="image"> <span class="image_title">Another title</span><br/> <img src="bar.png"/> </div> </li> <li> <div class="image"> <span class="image_title">Another title</span><br/> <img src="foo.png"/> </div> </li> </ul> </div>

Result:

enter image description here

Your code should look something like:

<div class="gallery"> <ul> <?php include_once("config.php"); $result = mysql_query("SELECT * FROM images"); while($res = mysql_fetch_array($result)) { ?> <li> <div class="image"> <a class="image_title" href="indimage.php?imageid=<?php echo $res['imageid']?>"><?php echo $res['imagename']?></a><br/> <a href="indimage.php?imageid=<?php echo $res['imageid']?>"><img src="<?php echo $res['image']?>" /></a> </div> </li> <?php } ?> </ul> </div>

You could bind to an object wrapper on an elements properties, or bind the elements en masse to your own do-something object. I found it easiest to have a pair of maps, registrants as keys object or user etc, and property name, then the maps keep the current values and (when i get to it) a generator or iterator will update the properties on the appropriate registrants. Below is an example without extending the nodeList prototype with array functions, I did the extension because looping can be well, you will see the code.

Here is some code I have in a codepen, on a project I started September 15. I am trying to get an interface for building and recording reading test passages and questions to maintain state, be able to recreate state, and offer some helpful clues about learning....

Code is redundant throughout, as I had never done the work before without the Observers Addi mentions above. In Polymer components you dont have to do your own binding. You could try that new spec v1 polymer two approach too. It has essentially a clean Object observe, and a lot of other cool features I just had a spec issue with some changes for contractual requirements.

8065171 0 rendering UIImage with size > 1024 with OpenGL ES 2.0 on the iPhone

I'm capturing a full resolution UIImage on the iPhone 4 (1936X2592)
then i'm scaling it to a square of size 1936x1936.

now i need to load this image into a texture and let OpenGL render it with some GLSL.

problem is OpenGL only supports power of 2 texture sizes and only up to 1024.

so how do i solve this?

Thank You.

EDIT: my question is irrelevant, i target 3GS and up and it supports 2048x2048 image size. my problem is another question: Camera frame to UIImage to OpenGL rendering gives an odd image (attached)

This is something that's usually done through the web server, so the answer depends on whether you're using Apache, Nginx, or something else. Here's how I do it with Nginx.

I typically have a directory in my site root called controllers. All of the files in controllers correspond to URL paths. For example:

/controllers/home.php ---> http://example.com/home /controllers/about.php ---> http://example.com/about /controllers/contact.php ---> http://example.com/contact

Then I use the web server (Nginx) to direct the traffic (which is what it's built to do). So if Nginx gets a request for http://example.com/home, then it looks in the controllers directory for a file called home.php. If the file exists, then Nginx serves it up. If the file doesn't exist, then Nginx serves up some fallback page. Here's what the Nginx configuration looks like:

server { listen 80; server_name example.com; root /srv/example; index index.php; rewrite ^/(.*)/$ /$1 permanent; location / { try_files $uri $uri/ /controllers$uri.php?$args; location ~ \.php$ { try_files $uri /index.php; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi_params; } } }

17237151 0 Add Custom Widget to another widget xml

I am developing a weather app like S4 weather app. This app also has a digital clock with it. I want to make other widget for digital clock in the same project and then add that widget to main widget. Hope you get the point. Here'the image link of what i am doing

Since this is my first project i am getting confused on how to add the clock widget in the main widget.

My activity_main.xml <LinearLayout> //some stuff <com.itcse.weather.DigitalClock xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/digitalClock" /> // some stuff </LinearLayout>

The GraphicalLayout of the activity_main.xml is showing

The following classes could not be instantiated: - com.itcse.weather.DigitalClock

which i know it should show since i haven't initialized the class anywhere. But i am getting confused in how to do it.

At present i have not done any coding in DigitalClock.java, simply set default layout in AppwidgetProvider. When i run the project on emulator i am getting a new widget of digital clock as option thus that means it is working.

I know i have to initialize DigitalClock Class in my AppWidgetProvider Configure but I am getting confused in how to do so.

I am using a DigitalClock separately since that is my custon digital clock and would need to set update period as 0. It would be unnecessary to set the update time of main widget as 0 so i am using this widget. Is this way right?

Also i want to ask something that when i finish this project can i upload it here and ask for some suggestions on what should i have actually done. Since this is my first project so i have done a lot of hit and trial and i don't know if i can do this, so i am asking you. Is this allowed??

UPDATE:- I think i am not making myself clear. Consider that i am making two seperate widgets in my same project. One is DigitalClock which has time and date. Another is main widget which has weather plus time and date. Now i want that to use DigitalClock in place of time and date in main widget. I have declared both widgets seperatly in manifest and they both are working correctly seperatly. Is this possible?

No, your code is not threadsafe assuming that the window handle (FWnd) is created in main (GUI) thread. A standard VCL approach is to call all GDI functions in GUI thread, via Synchronize or Queue methods of TThread class.

Check this blog:

Understanding "login failed" (Error 18456) error messages in SQL Server 2005

From the blog:

If the server encounters an error that prevents a login from succeeding, the client will display the following error mesage.

Msg 18456, Level 14, State 1, Server , Line 1 Login failed for user ''

Note that the message is kept fairly nondescript to prevent information disclosure to unauthenticated clients. In particular, the 'State' will always be shown to be '1' regardless of the nature of the problem. To determine the true reason for the failure, the administrator can look in the server's error log where a corresponding entry will be written. An example of an entry is:

2006-02-27 00:02:00.34 Logon Error: 18456, Severity: 14, State: 8. 2006-02-27 00:02:00.34 Logon Login failed for user ''. [CLIENT: ] n

The key to the message is the 'State' which the server will accurately set to reflect the source of the problem. In the example above, State 8 indicates that the authentication failed because the user provided an incorrect password.

The common error states and their descriptions are provided in the following table:
2 and 5 = Invalid userid 6 = Attempt to use a Windows login name with SQL Authentication 7 = Login disabled and password mismatch 8 = Password mismatch 9 = Invalid password 11 and 12 = Valid login but server access failure 13 = SQL Server service paused 18 = Change password required 

Hope this helps

One way to do it can be saving largest index, not value. You also need to return some value in case of empty array:

public static int largest(int[] nums3) { if (nums3.length == 0) { return -1; } int largestIndex = 0; for(int i=0; i < nums3.length; i++) { if(nums3[i] > nums3[largestIndex]) { largestIndex = i; } } return largestIndex; }

try saving those fetched images to the cache, then for each image check if the image already exists in the cache so that it doesn't have to be downloaded again.

4794870 0 Can I send more than one 'stream' of jpeg ByteArray data in a single URLRequest and output 2 images? Flash AS3 -> PHP

I have an AS3 swf which users can upload jpg images to my EC2 instances which sit behind and Elastic Load Balancer. The jpg images are converted into bytearray data and sent using URLLoader.load(URLRequest)

I make 2 calls when uploading, one to upload a large version, then another to upload a thumbnail version. A PHP script to which the bytearray data is uploaded converts this to a file using file_put_contents($destination, $GLOBALS["HTTP_RAW_POST_DATA"])

Is it possible to combine these two requests into a single request which contains both the bytearray data for the large and thumbnail images and 'split' the HTTP_RAW_POST_DATA to create 2 files at the server. This would be better than uploading the bytearray for the large version then using something like ImageMagick to resize the resulting image into a thumbnail which I realise is another option.

any suggestions? cheers

I had this problem also but it is on win10.. After I have tried a lots of different solution from web .. Finally.. it worked to change connection string to fix this problem.. But I changed "Provider=MSDAORA.1" to "Provider=OraOLEDB.Oracle"

Update

This works but @rdelmar's answer is much more compact.

/////////////////////////////////////////////////////////////////////////////////////////////////

I discovered an answer elsewhere on SO. Basically I had to use NSRange and check via the following method:

[string rangeOfString:@"hello" options:NSCaseInsensitiveSearch].location != NSNotFound

I also had to split my string before doing the check. So in the example words are separated by a period. I called:

NSArray *myArray = [string componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"."]];

and the looped through that array of strings doing the rangeOfString search. I set a BOOL so that once my string 'hello' was found it stopped searching.

You could use $index to show the number like so:

<div ng-repeat='item in names'> {{item.name}} <br> {{numbers[$index].number}} </div>

However, I would recommend putting the names and numbers in one object as that would be better practice.

There aren't any guaranteed reliable ways to do this. There are a number of methods that work some of the time, but there's no way to be certain. Most of the methods that could have been reliable are routinely blocked by end users due to spam.

The most common way is to send an HTML email with graphics that are loaded from your site (or quite frequently from a third-party tracking agency's site). The graphic would be loaded and the URL would be spiked with a unique ID so you know which recipient has loaded it.

However this only works if the user (a) reads their email in HTML mode, (b) allows it to load graphics, and (c) reads it while they're online.

Some techniques use Javascript to perform a similar task. But that has all the same issues, and can also be stopped by users blocking Javascript in their email.

The best method (ie the most socially acceptable one, and least likely to be blocked) is to provide a link for the user to click on to get more info, which has a unique ID. This of course doesn't tell you what's been read, but it does tell you who's interested in what they've read, which is probably more valuable to know anyway.

The down side of all these methods is the need to give each user a unique ID. This means that each email you send has to be unique, which means quite a big processing overhead for your mail system as it has to re-generate the text for every single user. This is the reason that most people who do this sort of thing delegate the task to a third party tracking agency.

enter image description here

Is it right?.Let's say when user click "Home", the bottom border will appear (under "Home" link).If so, just adds the css (your css) as shown in attached image. (.current_page_item) is the class added for CURRENT (selected) li. If home selected, then border-bottom will appear.

 header#top nav .sf-menu li.current_page_item > a, header#top nav .sf-menu li.current-menu-item > a, header#top nav .sf-menu li.current_page_item > a { border-style: solid; border-bottom: thick solid #27CCC0; }

If you want to see the live demo whether it works just like what you want, you can go to "inspect element" and click on 1(in my attached image).Then, add the css to 2(in my attached image).

And, Good Luck..Sorry if this is not the answer.

EDIT: added some details about explain().

Some general introduction: The Lucene Highlighter is meant to find text snippets from a hit document, and to highlight tokens matching the query.

Therefore, The TokenStream parameter is used to break the hit text into tokens. The highlighter's scorer then scores each token, in order to score fragments and choose snippets and tokens to be highlighted.
I believe you are doing it wrong. If all you want to do is understand which query terms were matched in the document, you should use the explain() method. Basically, after you have instantiated a searcher, use:

Explanation expl = searcher.explain(query, docId);

String asText = expl.toString();

String asHtml = expl.toHtml();

docId is the raw document id from the search results.

Only if you do need the snippets and/or highlights, you should use the Highlighter. If you still want to use the highlighter, follow Nicholas Hrychan's advice. Beware, though, as he describes the Lucene 2.4.1 API - If you use a more advanced version, you should use "QueryScorer" where he says "SpanScorer" .

11894358 0 Implementing iAd Banner

I just published an application on the App Store with an iAd banner. When I downloaded it to check for the advertisement, I just saw a plain white horizontal rectangle even though it says "Live: This app is receiving live ads." in development.

enter image description here

adView = [[ADBannerView alloc] initWithFrame:CGRectZero]; [adView setCurrentContentSizeIdentifier:ADBannerContentSizeIdentifierLandscape]; [adView setDelegate:self]; [self.view addSubview:adView]; [self.view bringSubviewToFront:adView]; - (BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave { return YES; }

Everything in my performance chart is zero, except for the 715 requests. What does this mean?

Also, is it possible for iAd to determine the user's location so that apple can put ads from local companies? For example, the user is in Japan, will iAd only show ads from Japan?

JavaScript does garbage collection automatically for you.

It might free it right away or it might wait when the moment is best. This is up to the JavaScript implementation.

So no, it won't cause a memory leak.

I am trying to rename a duplicate file name upon upload of a new file with the same name. Everything is working great except for that I am getting an error:

I'm trying to use file_get_contents on loop, in order to fetch JSON string from an URL continuously (every second). And i need to store the result into a javascript variable. Here was my approach, but i didn't get any result from this. My page showed me nothing but endless loading.

<?php set_time_limit(0); while(true) { $jsonContent=file_get_contents('http://megarkarsa.com/gpsjson.php'); echo $jsonContent; sleep(10); } ?>

And here my javascript code.

setInterval(function(){ var jsonUpdPostData = <?php echo $jsonContent; ?>; }, 100);

What should i do to make it work? Any suggestion will be appreciated.

Your order appears to be alphabetical, but since you didn't say this, I'm assuming this isn't a reliable expectation.

How's this?

If indeed the order IS is reliably alphabetical, it would be better to first sort your nodes rather than use a complex predicate as I have.

32321352 0 How to set CasperJS page options from within a test in test environment?

I run most of my CasperJS tests with the test command as well as the --ssl-protocol=anyand --ignore-ssl-errors=true flags.

Is there a way that I can add those 2 flags to the tests themselves if they're in the test environment? I know you can set page options if you use the casper module like var casper = require('casper').create({, but that's not how my tests are set up.

I also know you can do stuff like

casper.options.verbose = true; casper.options.logLevel = "debug";

...but casper.options.ignoreSslProtocol=true doesn't seem to work.

here's part of my login test --

var config = require('../../config'), x = require('casper').selectXPath; casper.test.comment('basic login test!'); casper.start(config.base_url); casper.test.begin('test basic login functionality', function (test) { casper.then(function() { this.click('.js-flip_box'); test.info('logging in'); this.fill('#login_form', { 'email': config.email, 'password': config.password }, true); }); casper.then(function () { test.assertVisible ('.home_bar', 'nav bar visible'); }); casper.run(function() { test.done(); }); });

...which I run with casperjs --ssl-protocol=any --ignore-ssl-errors=true test login.js (a mouthful)

am I doomed?

Another version of my solution with ranges:

List<int> getUniqueColors(int amount) { final int lowerLimit = 0x10; final int upperLimit = 0xE0; final int colorStep = (upperLimit-lowerLimit)/Math.pow(amount,1f/3); final List<int> colors = new ArrayList<int>(amount); for (int R = lowerLimit;R < upperLimit; R+=colorStep) for (int G = lowerLimit;G < upperLimit; G+=colorStep) for (int B = lowerLimit;B < upperLimit; B+=colorStep) { if (colors.size() >= amount) { //The calculated step is not very precise, so this safeguard is appropriate return colors; } else { int color = (R<<16)+(G<<8)+(B); colors.add(color); } } return colors; }

This one is more advance as it generates the colors that differ from each other as much as possible (something like @aiiobe did).

Generally we split the range to 3 subranges of red green and blue, calculate how many steps do we need to iterate each of them (by applying a pow(range,1f/3)) and iterate them.

Given the number 3 for example, it will generate 0x0000B1, 0x00B100, 0x00B1B1. For number 10 it will be: 0x000076, 0x0000EC, 0x007600, 0x007676, 0x0076EC, 0x00EC00, 0x00EC76, 0x00ECEC, 0x760000, 0x760076

Take a look at these UIView methods. You subclass can override these methods and do what you require.

touchesBegan:withEvent:, touchesMoved:withEvent:, touchesEnded:withEvent:, touchesCancelled:withEvent:

Implement these methods if you need to handle touch events directly. (For gesture-based input, use gesture recognizers.)

For the disabled attribute I think it's the presence of the attribute that disables the element regardless of its value.

It guess one of the reasons could be to allow more values than just yes/no in the future. For instance, instead of visible=true/false, you can have visibility=visible/hidden/collapsed

19926211 0 math.net DenseVectors vs DenseMatrix 1xn | nx1

This is really simple stuff but, as I am a noob with math.net, I may need to be pointed in the right direction:

let a = new DenseVector([| 5.0; 2.0; 3.0; |]) let m = new DenseMatrix(3, 3, 1.0) let r = a * m let r2 = m * a

results in:

> r;; val it : DenseVector = seq [10.0; 10.0; 10.0] > r2;; val it : DenseVector = seq [10.0; 10.0; 10.0]

Matrix-Vector multiplication takes too much liberty here. I need to enforce proper dimensionality checks. Should I just work with DenseMatrix, creating 1xn, nx1 matrices? This basically makes Vectors and DenseVectors redundant in my case.

As KD suggested, I would add name attributes to all the form elements.

<input type="text" name="length" value="8" id="length_field"> <input type="checkbox" id="includeLetters" checked>

etc...

but I would let the model binder give us strongly typed values by specifying the argument type.

[HttpPost] public ActionResult PasswordGenerator(int length, bool includeLetters, etc...) { }

If the number of arguments exceeds what you feel comfortable with, simply create an object with [properties that match your form field. IE:

public class PasswordGeneratorArguments { public int Length {get;set} public bool IncludeLetters {get;set} etc... }

34952970 0 "Another object on this page already uses ID 'XXXXXXX'

I've got a jQuery Multiselect Listbox control on my page:

jQuery(document).ready(function () { jQuery(function () { jQuery("#UCStyle1 select").multiselect({ header: true, height: 175, minWidth: 240, size: 3, classes: '', checkAllText: 'Check all', uncheckAllText: 'Uncheck all', noneSelectedText: '0 Selected', selectedText: '# selected', selectedList: 0, show: null, hide: null, autoOpen: false, multiple: true, position: {}, appendTo: "body" }); });

It's referenced a bunch of times in div tags like this:

So, they need to reference that jQuery, but they're different controls.

I'm getting the warning:

Multiple times.

Any idea how I can clean this up so that I don't get that warning? I think it's causing the page to look completely wonky on IE, but Firefox doesn't seem to care about it.

Just to elaborate on Injecteers answer actually the data:{} is what is posting information to it so may clash with params:[..]} :

<g:javascript> function go(){ var javaScriptVariable='123' $.ajax({ url:'${g.createLink( controller:'my', action:'go')}', data:{ param1: "${params.params1}", param2: javascriptVariable } }); } </g:javascript>

data:{} can also be data: $('form').serialize(); where serialize function grabs all the form elements and serializes it for you as params to be passed back.

I think you can use very fast solution with numpy.where:

homework2['ADJ_HDI'] = np.where(homework2['HDI'] > .5, homework2['HDI'], 0)

Timings:

import pandas as pd import numpy as np homework2 = pd.DataFrame({"A": [10, 8, 1, 1, 2, 2, 2], "HDI": [25, np.nan, 2.3, 2.4, 1.2, 0.3, 5.7]}) #for test 7k uncomment row bellow #homework2 = pd.concat([homework2]*1000).reset_index(drop=True) print homework2 h = homework2.copy() h1 = homework2.copy()

def a(mydataframe): def adj_hdi(row): hdi = row['HDI'] if hdi>.5: return hdi else: return 0 mydataframe['ADJ_HDI'] = mydataframe.apply(lambda row: adj_hdi(row), axis = 1) return mydataframe def b(homework2): homework2['ADJ_HDI'] = 0 homework2.loc[(homework2['HDI'] > 0.5), ['ADJ_HDI']] = homework2['HDI'] return homework2 def c(homework2): homework2['ADJ_HDI'] = np.where(homework2['HDI'] > .5, homework2['HDI'], 0) return homework2 print a(homework2) print b(h) print c(h1)

len(homework2) = 7:

In [2]: %timeit a(homework2) 1000 loops, best of 3: 376 µs per loop In [3]: %timeit b(h) The slowest run took 4.62 times longer than the fastest. This could mean that an intermediate result is being cached 1000 loops, best of 3: 1.49 ms per loop In [4]: %timeit c(h1) The slowest run took 5.52 times longer than the fastest. This could mean that an intermediate result is being cached 1000 loops, best of 3: 283 µs per loop

len(homework2) = 7k:

In [7]: %timeit a(homework2) 10 loops, best of 3: 106 ms per loop In [8]: %timeit b(h) 100 loops, best of 3: 2.63 ms per loop In [9]: %timeit c(h1) The slowest run took 5.30 times longer than the fastest. This could mean that an intermediate result is being cached 1000 loops, best of 3: 324 µs per loop

The usual approach to this is to treat either the first or the last printf as a special case (outside of the loop):

for(ii=0; ii<2; ii++) { jj = 0; printf("%d", jj); // first number printed without space. for(jj=1; jj<4; jj++) { printf(" %d", jj); // include the space before the number printed } if(ii<2-1) printf("\n"); }

Obviously I simplified how the loops are constructed and what is printed - for simplicity. You could make the first printf statement

printf("\n%d", jj);

then you have a newline at the start of your output (often a good thing) and then you don't need the if statement later - you just don't have a newline printed at the end of the line (because it will be printed at the start...)

There are marginally more efficient ways of doing this that would involve no if statements at all - but these all come at the expense of less readable code. For example, here is a "no loop unrolling and no additional if statements" version of the code:

http://codepad.org/01qPPtee

#include <stdio.h> int main(void) { int ii, jj; ii = 0; while(1) { jj = 0; while(1) { printf("%d", jj); // include the space before the number printed jj++; if(jj<4) printf("."); else break; } ii++; if(ii<2) printf("*\n"); else break; } return 0; }

Output:

0.1.2.3* 0.1.2.3

Basically I have taken the functionality of the for loop and made it explicit; I also use a . rather than a and "*\n" rather than "\n" to show in the printout that things behave as expected.

It does what you asked without extra evaluation of the condition. Is it more readable? Not really...

id:

It will identify the unique element of your entire page. No other element should be declared with the same id. The id selector is used to specify a style for a single, unique element. The id selector uses the id attribute of the HTML element, and is defined with a "#".

class:

The class selector is used to specify a style for a group of elements. Unlike the id selector, the class selector is most often used on several elements.

This allows you to set a particular style for many HTML elements with the same class.

The class selector uses the HTML class attribute, and is defined with a "."

The reason .NET could not "just" sort your Customer objects is because it has no way of guessing in what way you want to sort them: by salary, by first name, by last name, by the time they placed their first order, etc.

However, you can make it work without implementing IComparable in three different ways:

Pass a separate IComparer<Customer> implementation - this lets you move comparison logic to a separate class, and apply different comparison logics based on a situation.
Pass a Comparison<Customer> delegate - same as above, but now you don't need a separate class; this lets you provide comparison logic in a lambda.
Use LINQ's OrderBy instead - Similar to above, but gives you additional capabilities (filtering, projecting, grouping, etc.)

8695891 0 Is there any way to work with a Node stream as an iterable?

I’m writing a tool which processes a bunch of text passed in to stdin, each line is an “entry”. I’d like to make my code more functional, so I’d like to treat the set of lines as a “sequence” or “iterable” and iterate over it using reduce.

I’m currently using the Node module LineStream to process stdin as a set of lines, but it works by dispatching a data event for each line — which is fine, it’s implementing the Readable Stream interface.

So I’m currently doing kind of a very “manual” reduce by passing the interim value in to my function every time the data event fires:

var windows = []; linestream.on('data', function(line) { return windows = rollup(windows, extractDate(line), argv.w); }); linestream.on('end', function() { return process.stdout.write(toCsv(windows)); }); process.stdin.resume();

But it’d be more functional to do something like:

linestream.lines.reduce(rollup, []); function rollup(windows, line) { // would return a new interim or final value }

Of course, I could “collect” all the lines into a regular array and then reduce it, but I tried that and it uses way too much memory when I’m running my tool on a large dataset — so something like iteration over the stream is really what’s necessary.

I guess what I’m asking is whether it’s possible to write a Node function/module which would do this, or whether one exists already.

Thanks!

v &= -signed(v) will clear all but the lowest set bit (1-bit) of v, i.e. extracts the least significant 1 bit from v (v will become a number with power of 2 afterwards). For example, for v=14 (1110), after this, we have v=2 (0010).

Here, using signed() is because v is unsigned and you're trying to negate an unsigned value (gives compilation error with VS2012) (comment from JoelRondeau). Or you will get a warning like this: warning C4146: unary minus operator applied to unsigned type, result still unsigned (my test).

40619482 1 Is it possible to execute QPDF through Python script

I'm working on a python script that processes PDF files, though some of them contain encryption that restricts usage to only printing, which I have to manually remove before I can process them.

For that I have been manually using QPDF to remove these restrictions on individual PDF files before running the script (the commands for qpdf are pretty simple...inside the command prompt -> qpdf --decrypt input.pdf output.pdf)

My question is - rather than doing this bit manually, is it possible to execute the QPDF executable file within my Python script and run the command? I haven't been able to find any python modules specifically to control QPDF so I am not holding much hope.

A properly normalized database will look nothing like a proper object-oriented design. The needs of a database are very different from the needs of a software application.

You should design your application according to the requirements for how it is to be used. What sorts of things is the application supposed to do? What objects will be required to support those needs? And what are the natural relationships between them?

A single business object may be stored across a dozen database tables, or a single table may store data for a dozen objects. It really depends on the specifics of the system you are working with.

14756318 0 How to disable a User Control to draw it's background (or Region)

My question : How to disable a User Control to draw it's background (or Region)

Note : I already tried to override and empty OnPaintBackground or set background color to transparent.

I'm trying to bypass winform paint for my custom user controls in a custom container. For that I thought to give a try to this : Beginners-Starting-a-2D-Game-with-GDIplus

My setup is :

A Form containing:
- A User control (DrawingBoard)
- A Container with elements I can drag and drop to this DrawingBoard (it's a listbox).

My render loop is inside the DrawingBoard with all elements specified in the previous link.

public DrawingBoard() { InitializeComponent(); //Resize event are ignored SetStyle(ControlStyles.FixedHeight, true); SetStyle(ControlStyles.FixedWidth, true); SetStyle(System.Windows.Forms.ControlStyles.AllPaintingInWmPaint, true);// True is better SetStyle(System.Windows.Forms.ControlStyles.OptimizedDoubleBuffer, true); // True is better // Disable the on built PAINT event. We dont need it with a renderloop. // The form will no longer refresh itself // we will raise the paint event ourselves from our renderloop. SetStyle(System.Windows.Forms.ControlStyles.UserPaint, false); // False is better } #region GDI+ RENDERING public Timer t = new Timer(); //This is your BackBuffer, a Bitmap: Bitmap B_BUFFER = null; //This is the surface that allows you to draw on your backbuffer bitmap. Graphics G_BUFFER = null; //This is the surface you will use to draw your backbuffer to your display. Graphics G_TARGET = null; Size DisplaySize = new Size(1120, 630); bool Antialiasing = false; const int MS_REDRAW = 32; public void GDIInit() { B_BUFFER = new Bitmap(DisplaySize.Width, DisplaySize.Height); G_BUFFER = Graphics.FromImage(B_BUFFER); //drawing surface G_TARGET = CreateGraphics(); // Configure the display (target) graphics for the fastest rendering. G_TARGET.CompositingMode = CompositingMode.SourceCopy; G_TARGET.CompositingQuality = CompositingQuality.AssumeLinear; G_TARGET.SmoothingMode = SmoothingMode.None; G_TARGET.InterpolationMode = InterpolationMode.NearestNeighbor; G_TARGET.TextRenderingHint = TextRenderingHint.SystemDefault; G_TARGET.PixelOffsetMode = PixelOffsetMode.HighSpeed; // Configure the backbuffer's drawing surface for optimal rendering with optional // antialiasing for Text and Polygon Shapes //Antialiasing is a boolean that tells us weather to enable antialiasing. //It is declared somewhere else if (Antialiasing) { G_BUFFER.SmoothingMode = SmoothingMode.AntiAlias; G_BUFFER.TextRenderingHint = TextRenderingHint.AntiAlias; } else { // No Text or Polygon smoothing is applied by default G_BUFFER.CompositingMode = CompositingMode.SourceOver; G_BUFFER.CompositingQuality = CompositingQuality.HighSpeed; G_BUFFER.InterpolationMode = InterpolationMode.Low; G_BUFFER.PixelOffsetMode = PixelOffsetMode.Half; } t.Tick += RenderingLoop; t.Interval = MS_REDRAW; t.Start(); } void RenderingLoop(object sender, EventArgs e) { try { G_BUFFER.Clear(Color.DarkSlateGray); UIPaint(G_BUFFER); G_TARGET.DrawImageUnscaled(B_BUFFER, 0, 0); } catch (Exception ex) { Console.WriteLine(ex); } } #endregion

Then my elements get the event fired and try to draw what I would like:

public override void UIPaint(Graphics g) { Pen p = new Pen(Color.Blue,4); p.Alignment = System.Drawing.Drawing2D.PenAlignment.Inset; g.DrawLines(p, new Point[] { new Point(Location.X, Location.Y), new Point(Location.X + Width, Location.Y), new Point(Location.X + Width, Location.Y + Height), new Point(Location.X, Location.Y + Height), new Point(Location.X, Location.Y - 2) }); g.DrawImageUnscaled(GDATA.GetWindowImage(), Location); }

here is what happening on my DrawingBoard :

As I can't post image ... here is the link : http://s8.postimage.org/iqpxtaoht/Winform.jpg

The background is DarkSlateGray because my G_BUFFER state to clear each tick with that, Ok
The blue rectangle is what I paint, but it get cropped, KO
The Texture is cropped, KO
The region that crop my drawing is the control size.

So from there I've tried everything I could to disable WinForm to make some magic drawing in background. Tried to override and empty everything that got paint/update/refresh/invalidate/validate on Form/DrawingBoard/Elements but nothing allowed me to get my texture or drawing to not get cropped by the control background : (

I also tried to set the background of the Element as transparent and also to set Form.TransparencyKey = blabla with each element BackColor = blabla. But failed each time.

I'm certainly missing something : / But I don't know what.

33638749 0 BIRT Report Generation - How do I keep all row data?

My question has to do with the output that is generated when I run a BIRT report.

Normally, a BIRT report would not show the duplicate portion of each row of data that is written to a report. For instance, if I were generating a report that were to contain multiple lines (rows) of data and the data was organized by a 'Group ID'. The data, for each specific Group ID would be shown indented and organized by each Group ID. The Group ID would be shown in the first row of output, but for subsequent rows of data (for that same Group ID), the Group ID would not be shown. In otherwords, no need to display the same Group ID over and over in the report. This method helps to keep the clutter down and makes the report easier to read.

I have a customer who doesn't want the report generated this way. The specifications are to show each row of report data as if it were directly from a SQL query.

Is there a way to have the BIRT report show all data during the report generation? I've looked all over and still haven't come up with any ideas.

Thanks!

Assuming my understanding is correct you just need to:

numpy.logical_and.reduce(features[index] == features)

Here we first produce the matches between all rows and feature[index] with:

features[index] == features

Then, we reduce the matrix, which effectively tests, for a column j, if features[index][j] == features[j] for all i

As an example:

>>> features = numpy.asarray(numpy.random.randint(2, size=(5, 10)), dtype=bool) >>> features array([[False, True, True, True, False, False, True, False, False, False], [ True, False, True, True, True, True, True, True, False, True], [ True, False, True, False, False, True, True, True, True, True], [False, False, True, False, True, False, False, True, False, True], [False, True, True, True, False, True, False, True, True, True]], dtype=bool) >>> numpy.logical_and.reduce(features[3] == features) array([False, False, True, False, False, False, False, False, False, False])

If "C:\test.txt" exists and is hidden, then following code fails (h = INVALID_HANDLE_VALUE) :

h = CreateFile("C:\\test.txt", GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, 0, 0);

this fails too (argument 6 == FILE_ATTRIBUTES_NORMAL or argument6 == 0 seems so be the same) :

h = CreateFile("C:\\test.txt", GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, 0);

but this works :

h = CreateFile("C:\\test.txt", GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_HIDDEN, 0);

So roughly in other words : if the file already exists and is hidden then CreateFile with "CREATE_ALWAYS" fails if argument 6 != FILE_ATTRIBUTE_HIDDEN.

There's a pretty nice tool called UML Pad.

Without the Location property, in addition to the server side caching, the output cache provider also tells the client (browser) to cache the response for the duration given on the attribute properties. To prevent this you need to use the Location property of the OutputCacheAttribute

Changing your attribute to this will solve your problem:

[OutputCache(Duration = 120, Location=OutputCacheLocation.Server)]

This is probably a stupid solution because I'm terrible and lazy, but here is my crazy work-around:

In the head:

<script type="text/javascript"> function fixmyheight(h) { document.getElementById('fixme').style.height = h + "px"; } </script>

And then in the body:

<ul id="fixme"> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> <li>Item 4</li> <li>Item 5</li> <li>Item 6</li> </ul>

Sorry, I screwed that up at first. Fixed now.

A few quick notes:

Please don’t use eval(). There are very, very few cases where it’s needed, and it has performance and security implications.
You’ve discovered that JavaScript doesn’t have “variable variables” (the ability to get or set a variable by name), which is why you had to resort to eval(). When you need to look something up out of a set, don’t use a bunch of numbered variables. Try an array or an object instead.
Objects in JavaScript don’t get copied when you assign them to variables. The line
```
var arrayExtended = arrayGiven; 
```
doesn't make a copy of arrayGiven — arrayExtended ends up being a variable which points at the same array. So, when you change something in arrayExtended, it also changes it in arrayGiven. If you need to copy an array in JavaScript, use .slice() with no arguments:
```
var arrayExtended = arrayGiven.slice(); 
```
Some other things in JavaScript, like objects, are trickier to copy.
What are you trying to do here? (mainArray is already an array) This is going to create a string which is a “[”, followed by the string representation of mainArray (each item in the array separated by commas), followed by “]”. Slimbox won’t know what to do with it.
```
jQuery.slimbox("[" + mainArray + "]",startAtImage); 
```
If you do want to wrap something in an array, just put brackets around it like you did up above:
```
[mainArray]; 
```

I think your main problem is "[" + mainArray + "]". With those tips, you should be able to make your code work (and, without eval()). But, I want to show you my approach to this problem too. It’s below.

I’m storing the names and descriptions of all the images in an array. Because arrays in JavaScript (and a lot of other programming languages) start at 0 instead of one, I subtracted one from all the image numbers in the arrays that specify the order.

var album = "summer", images = [ [ { name: "1", description: "Description #1" }, { name: "4", description: "Description #4" }, { name: "5", description: "Description #5" } ], [ { name: "2", description: "Description #2" }, { name: "6", description: "Description #6" } ], [ { name: "3", description: "Description #3" } ] ], order = [0, 2, 1], startAtImage = 0, slimboxImages = Array.prototype.concat.apply([], order.map(function(id){ return images[id]; })) .map(function(image){ return [ 'img/' + album + '/' + image.name + '.jpg', image.description]; }); jQuery.slimbox(slimboxImages, startAtImage);

Ok, so in that activity i have a FAB button that switches between views, when it switches to comment view it requests all comments for that picture, and in comment view i can upload a new comment. Everything works fine except this: for example if i spam the FAB button lets say 6 times and i end up on comment view and upload a new comment, on my tomcat server log i will get

EG. Got Connection Got Connection Got Connection Got Connection Got Connection Got Connection Do we have something here? uploadedComment

The dilemma here is : Is it a memory leak, and if it is how do i make a brand new call every time. Or does the System.out.print write everything in the end, and if it is why doesn't it write Got connection everytime i swipe the screen and it downloads the new comments. If someone could clarify this i would be really really greatfull! Thanks :D

32380247 0 aspx page not getting cached on the browser

No matter what I do I cannot seem to cache my aspx pages locally on the browser. The first request for a page after login goes to the server and retrieves it from there. The 2nd request onwards, the pages are fetched form local cache. However as soon as I signout and sign back in, the same page is yet again fetched from the server and not taken from the cache locally.

URL of my page is as follows:

http://mywebsite.net/page1.aspx?v=2015_3.0&ln=en-EN&sid=612e0d3f-f29d-4b98-b4f7-6788e5a35a03

Response Header of the Page looks like this:

Can anyone please suggest why would the browser not take the page from local cache?

There is no point in representing it as a mathematical function because it won't save you any computations.

Indeed all you need is the weights, biases, activation and your architecture. I'm assuming it is a simple feedforward network as you said, you need to implement some kind of matrix multiplication and addition in C. Also, you'll need to implement the activation function. After that, you're ready to go. Your feed forward NN is ready to be implemented. If the C code will not be used for training, it won't be necessary to implement the backpropagation algorithm in C.

A feedforward layer would be implemented as follows:

Output = Activation_function(Input * weights + bias)

Where,

Input: (1 x number_of_input_parameters_for_this_layer)

Weights: (number_of_input_parameters_for_this_layer x number_of_neurons_for_this_layer)

Bias: (1 x number_of_neurons_for_this_layer)

Output: (1 x number_of_neurons_for_this_layer)

The output of a layer is the input to the next layer.

You don't have just one line-break but more. . is just recognizing symbols, but no white-spaces, line-breaks or things like those. Additional to that, when you use the * then you don't need a ? anymore.

So a valid rule for your example would be: <w:p (.|\s)*<w:t>(.|\s)*</w:p>

No. Long answer: There are at least two completely different branches of the .NET Framework. The desktop/server ones which are the ones you want access to and the Silverlight ones which include the Windows Phone and XNA branches.

It is possible to write libraries that work with both branches of frameworks in binary form, but they cannot use any API save very fundamental stuff. Especially UI and IO is off limits. So in practice, you have two worlds that are incompatible on a binary level. This is very sad, but that's how it is and it can't changed without breaking backward compatibility.

So as others said, even with elevated privileges, you need to write a separate software in the main .NET framework and communicate with it over COM or Silverlight's host environment.

33089211 0 Catch-all Exception Handler for non-UI Threads in WPF

Specifically, I'm using WPF with MVVM. I have a MainWindow, which is a WPF Window where all of the action happens. It uses a corresponding View Model class for its properties, commands, etc.

I have set up main UI thread and non-UI thread exception handlers in Application.xaml.vb StartUp like this:

Private Sub Application_DispatcherUnhandledException(sender As Object, e As Windows.Threading.DispatcherUnhandledExceptionEventArgs) Handles Me.DispatcherUnhandledException ' catches main UI thread exceptions only ShowDebugOutput(e.Exception) e.Handled = True End Sub Private Sub Application_Startup(sender As Object, e As StartupEventArgs) Handles Me.Startup ' catches background exceptions Dim currentDomain As AppDomain = AppDomain.CurrentDomain AddHandler currentDomain.UnhandledException, AddressOf UnhandledExceptionHandler AddHandler System.Threading.Tasks.TaskScheduler.UnobservedTaskException, AddressOf BackgroundTaskExceptionHandler End Sub Sub UnhandledExceptionHandler(sender As Object, args As UnhandledExceptionEventArgs) Dim ex As Exception = DirectCast(args.ExceptionObject, Exception) ShowDebugOutput(ex) End Sub Sub BackgroundTaskExceptionHandler(sender As Object, args As System.Threading.Tasks.UnobservedTaskExceptionEventArgs) Dim ex As Exception = DirectCast(args.Exception, Exception) ShowDebugOutput(ex) End Sub

This part works

When I try to test this out, by deliberately throwing an exception, it works. It is actually in the View Model in the Sub that handles the Select All button click.

The button:

<Button Content="Select All" Height="23" Width="110" Command="{Binding SelectAllCommand}" />

The Command where I'm throwing the exception that is successfully caught:

Private Sub SelectAll() Throw (New Exception("UI Thread exception")) SetAllApplyFlags(True) End Sub

This part doesn't work

There's another button in the same MainWindow similarly bound to a command. However, it uses a Task to perform its work in the background, and an exception thrown in there does NOT get caught by my catch-all handlers.

Private Sub GeneratePreview() ' run in background System.Threading.Tasks.Task.Factory.StartNew( Sub() ' ... stuff snipped out, issue is the same with or without the rest of the code here ... Throw (New Exception("Throwing a background thread exception")) End Sub) End Sub

There are several similar questions, but I haven't been able to actually figure out my answer from them. The AppDomain UnhandledException seems to be the answer in most cases, but it isn't for mine. What exactly do I have to add to be able to catch an exception that might be thrown in a non-UI thread this way?

What I ended up doing

I could not get the TaskScheduler.UnobservedTaskException event to call my event handler when I was handling it in Application.xaml.vb. But I took hints from the other answer, and I'll mark it as the answer because it ultimately helped.

However, it is not at the application level, so if this was a larger application, I'd have to duplicate this in every instance where I used a Task. This wasn't really what I was looking for, but not willing to spend more time on it now.

I ended up putting a try-catch inside the Task. In the catch, I was able to use Dispatcher.Invoke to still display a user-friendly dialog with the exception info.

Private Sub GeneratePreview() ' run in background System.Threading.Tasks.Task.Factory.StartNew( Sub() Try ' ... stuff snipped out, issue is the same with or without the rest of the code here ... Throw (New Exception("Throwing a background thread exception")) Catch ex As Exception Application.Current.Dispatcher.Invoke(DispatcherPriority.Normal, DirectCast( Sub() HRNetToADImport.Application.ShowDebugOutput(ex) End Sub, Action)) End Try End Sub) End Sub

You can only use one character per range in a regex and most regex parsers don't understand multiple bytes using the \x notation. Use the \u notation instead.

(:|[A-Z]|_|[a-z]|[\xC0-\xD6]|[\xD8-\xF6]|[\xF8-\u02FF]|[\u0370-\u037D]|[\u037F-\u1FFF]|[\u200C-\u200D]|[\u2070-\u218F]|[\u2C00-\u2FEF]|[\u3001-\uD7FF]|[\uF900-\uFDCF]|[\uFDF0-\uFFFD]|[\u10000-\uEFFFF])

The .NET regex documentation states

\x20 Matches an ASCII character using 2-digit hexadecimal. In this case, \x2- represents a space.

And for unicode:

\u0020 Matches a Unicode character using exactly four hexadecimal digits. In this case \u0020 is a space.

So I've used both above, \x for the 2-char hex values and \u for the larger ones.

You can most certainly do anything with K2 from MVC. They have a full range of APIs (web services, dlls, etc.). You can view the developers reference here.

Your K2 installation contains all the *.dll's you need. The default location is C:\Program Files (x86)\K2 blackpearl\Bin.

Here is a simple example of starting a workflow using the SourceCode.Workflow.Client.dll: (NOTE: I write my own class libraries to handle all of my K2 interactions, to separate the work OUT of my controllers, but you could simply place the method below in your controller if you wanted).

using SourceCode.Workflow.Client; public class MySampleK2Service: IMySampleK2Service { private readonly string serverHost; private readonly string impersonatedUser; public MySampleK2Service(string serverHost, string impersonatedUser) { this.serverHost = serverHost; this.impersonatedUser = impersonatedUser; } public int StartNewWorkflow(string processName, string folio) { using (var connection = new Connection()) { connection.Open(this.serverHost); if (this.impersonatedUser != null) { connection.ImpersonateUser(this.impersonatedUser); } var processInstance = connection.CreateProcessInstance(processName); processInstance.Folio = folio; connection.StartProcessInstance(processInstance, true); return processInstance.ID; } } }

In XAML there are four possible Stretch options:

None
The image is shown in it's original size. If its larger than the parent element, it'll only show the top left portion of the image that fits inside. If the image is smaller than the parent element, then it's shown in it's entirety.

Fill
The image is resized to fill the parent element. If the aspect ratios are different, then the image will be stretched to fit the parent. This will distort the image.

Uniform
The image will be scaled up as large as it can be, while still being completely inside of the parent. Unlike Fill which will stretch the image to make it fit perfectly, Uniform will keep the aspect ratio of the image and stop scaling when it reaches the bounds of the parent.

UniformToFill This is the bastard child of the previous two. It will scale the image, while keeping the aspect ratio, until it fills the parent element. This means that some parts of the image will be clipped if the aspect ratios are different.

For more information on the Stretch enumeration, hit it up on MSDN

UPDATE
If you want to show the image outside of the bounds of the parent you could do something like this:

<Grid Width="100" Height="50"> <Grid.Clip> <RectangleGeometry Rect="0 0 100 50"/> </Grid.Clip> </Grid>

27474172 0 Using Socket.io, AngularJS and Express, client listening on different port than which the server is running at

I was trying to implement a chat application with authentication. I followed this tutorial to make the chat application which uses Socket.io.

When I used this tutorial the server is listening at port 8000 whereas the client is running at port 8100. The Socket URL is at 8000 and the chat application is working perfectly. However when I try to use methods of Express such as app.get(), I cant seem to make it work. I think the cause is that the port of the local host is 8100 and I am listening on 8000. I am using app.get() and AngualrJS to authenticate using PassportJS. Please can someone help me out as I have been stuck on this for a while. Thanks and I would really appreciate any help. Maybe I am thinking about this the wrong way.

This is using the Service-Locator anti-pattern. It will work, but you lose the flexibility of IoC and add a dependency everywhere that is difficult to test.

This simple answer is that you can add "KernelContainer.Inject(this)" to your HttpHandler. Or you can create a custom module (or modify the existing Ninject.Web one) to do injection before handler execution.

There is a String constructor for this problem:

var s = String(count: 10, repeatedValue: Character(" "))

You need to keep the selected item index inside pager adapter instead. And on click of any item inside a fragment change that value.

interface ItemSelectionInterface{ void onItemSelectionChanged(int fragmentPosition,int itemIndex); int getSelectedItemOnFragment(int fragmentPosition); }

implement above interface in PagerAdapter:

class YourPagerAdapter....... implements ItemSelectionInterface{ int selectedFragment,selectedItem; @Override public Fragment getItem(int position) { return GridFragment.getInstance(position-(Integer.MAX_VALUE / 2),this); } @Override public int getCount() { return Integer.MAX_VALUE; } void onItemSelectionChanged(int fragmentPosition,int itemIndex){ selectedFragment=fragmentPosition;selectedItem=itemIndex; } int getSelectedItemOnFragment(int fragmentPosition){ if(fragmentPosition!=selectedFragment) return -1; return selectedItem; } }

Change your GridFragment to:

class GridFragment ....{ ItemSelectionInterface selectionInterface; @Override public void setMenuVisibility(final boolean visible) { super.setMenuVisibility(visible); if (visible) { mAdapter.notifyDataSetChanged(); } } public static GridFragment getInstance(int position, ItemSelectionInterface selectionInterface){ ........... ........... this.selectionInterface=selectionInterface; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_calednar, container, false); mAdapter = new CalendarGridViewAdapter(getActivity(), getDateTime(position), MONDAY); mAdapter.setSelectionInterface(selectionInterface); mGridView = (GridView) rootView.findViewById(R.id.gridView); mGridView.setAdapter(mAdapter); // TODO handle on item click listener mGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { selectionInterface.onItemSelectionChanged(position,i); mAdapter.notifyDataSetChanged(); } }); } return rootView; }

And finally in adapter:

 ItemSelectionInterface selectionInterface; //Create a setter for int position;//create a setter @Override public View getView(int i, View convertView, ViewGroup viewGroup) { // if (convertView == null) { LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Activity.LAYOUT_INFLATER_SERVICE); convertView = inflater.inflate(R.layout.grid_item_day, null); //} TextView txt = (TextView) convertView.findViewById(R.id.dayText); txt.setText(""+datetimeList.get(i).getDay()); View actSelection = convertView.findViewById(R.id.actSelection); actSelection.setVisibility(View.INVISIBLE); if(selectionInterface.getSelectedItemOnFragment(position)== i){ actSelection.setVisibility(View.VISIBLE); } .... return convertView; }

You have syntax error. First set the class into a variable, and then concat it to your string:

$class = 'label label-sm label-info'; //sets the default value $status = 'Processing'; if ($row->status == 2) { $class = 'label label-sm label-success'; $status = 'Approved'; } else if ($row->status == 1) { $class = 'label label-sm label-warning'; $status = 'Waiting'; } $row->status = '<span class="' . $class . '">' . $status . '</span>';

I suggest you to use an IDE like Netbeans, PHPStorm, etc... Those tools are shows you your syntax errors when you are coding.

12360960 0 how to get each element in one record from mysql database

I am trying to get each element in one record 'Pests' in database 'crop'.Actually my purpose is to get all the distinct pests in 'Pests' field.

BUT There are not only one element in 'Pests' in database. For example:

Name Pests

Name1 Grasshopper Thrips Potato Leafhoppe Stink Bugs ... ... Name2 Green Cloverworm Mexican Bean Bettle ... ...

My code is like the following. But the result is not what I want. This will display all the pest in each column. But I want all the distinct pests in all column and display each pest in a table, like

Pest | Grasshopper|Thrips|Potato Leafhoppe|Stink Bugs|Green Cloverworm|Mexican Bean Bettle|... ...

Im so appreciate if anyone could give me some hint for how to achieve this. Thanks so much!

$search = "SELECT distinct Pests from crop ORDER BY Pests ASC"; $result = mysql_query($search); echo '<table>'; echo '<tr>'; while ($rs = mysql_fetch_row($result)){ echo '<td>'.$rs[0].'</td>'; } echo '</tr>'; echo '</table>';

You can use BindingUtils to get notified when the dataProvider property of the combo box changes:

BindingUtils.bindSetter(comboBoxDataProviderChanged, comboBox, "dataProvider");

BindingUtils lives in the mx.binding.utils package.

I have a longer description of how to work with BindingUtils here: Does painless programmatic data binding exist?

You don't need to create a new thread to deal with the EndRequest or EndResponse callback - these will be called for you on a background thread from the ThreadPool. So something like your first code example should work.

If you don't like the nested lambdas just declare named methods :). You can pass state information in the Begin... methods which you can retrieve in the result object.

What you're asking is kind of weird - you're wrapping an async framework with sync version, and rewrapping that with an async version. It sounds like you're creating extra work for yourself in order to stay faithful to your port. You will also use some extra memory to keep an extra thread alive doing nothing (1MB for the stack at least).

If you still want to do it check out this link though.

For low volumes only, yes

You're better to try to INSERT and UPDATE on error. You can assign values with the OUTPUT clause

DECLARE @stuff TBLE (...) BEGIN TRY ... BEGIN TRY INSERT table1 OUTPUT ... VALUES ...() END TRY BEGIN CATCH IF ERROR_NUMBER = 2627 UPDATE table1 SET ... OUTPUT ... ELSE RAISERROR ... END CATCH ... END TRY BEGIN CATCH ... END CATCH

Edit:

Several other answers from me:. Hopefully you get the idea.

You can do the following:

Right click on the file and choose "View History"
On the history tab choose the two revisions you'd like to compare
Finally click on one of the selected revisions and choose "Compare..."

Here's a version of the code that runs on seperate threads. The code you provided above wasn't running a message loop on the second thread. Also setting CheckForIllegalCrossThreadCalls = false is a really bad idea for what you're trying to achieve.

Usage:

 ProgressForm.Initialise() ProgressForm.ShowProgressForm("hello", "hello") Dim modalForm As New Form With {.Text = "MyModalForm"} modalForm.ShowDialog() ProgressForm.HideProgressForm() ProgressForm.TearDown()

And here's the ProgressForm definition.

Public Class ProgressForm Inherits Form Private Shared sForm As ProgressForm Private Shared sThread As Thread Public Sub New() Me.TopMost = True Me.BackColor = Color.Green Me.Text = "Progress" End Sub Public Shared Sub Initialise() 'Create the form sThread = New Thread(AddressOf ThreadFunc) sThread.Start() While sForm Is Nothing OrElse sForm.InvokeRequired = False Thread.Sleep(0) End While End Sub Public Shared Sub TearDown() sForm.BeginInvoke(Sub() Application.ExitThread()) End Sub Private Shared Sub ThreadFunc() sForm = New ProgressForm 'Dim handle = sForm.Handle Application.Run(sForm) End Sub Public Shared Sub ShowProgressForm(caption As String, title As String) If sForm.InvokeRequired Then sForm.BeginInvoke(Sub() ShowProgressForm(caption, title)) Else sForm.Text = title 'TODO: Caption sForm.Visible = True sForm.TopMost = True End If End Sub Public Shared Sub HideProgressForm() If sForm.InvokeRequired Then sForm.BeginInvoke(Sub() HideProgressForm()) Else sForm.Visible = False End If End Sub Private Sub ProgressForm_FormClosing(sender As Object, e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing If e.CloseReason = CloseReason.UserClosing Then Me.Visible = False e.Cancel = True End If End Sub End Class

Although I get an error at the below line stating

The method subscribe(String...) in the type KafkaConsumer is not applicable for the arguments (List)

consumer.subscribe(Arrays.asList("storm-test-topic"));

This seems correct as per the api docs. Here is the dependency version

Am I missing something? Thanks

You must know the source encoding.

As far as I can tell from my experiments each top-level test, ie each test named in the load test, gets its own copy of the data sources of called tests. Hence even though the data source is attached to the called (ie login) test each calling test will use all of its values.

My experiment: A very simple web test named Called has a CSV data source having 100 rows and a column containing the row number. This web test just visits http://localhost/ and expects a 404 response. A WebTestPlugin has a PostWebTest method that writes the data source's row number field plus the context parameters $WebTestIteration and WebTestUserId to a log file. A second test has as its only actions (1) a call of Called and (2) a call of the plugin. Made copies of this second test and gave them the names Caller1, Caller2 and Caller3. These three tests are used in a load test for 6 virtual users for 2 minutes duration. The log file clearly shows that each CSV row is used by each of the three top-level tests.

It seems that ie and table widths don't play nicely together.

What you can do to enforce a minimum width for your table is to add an extra row to your table which spans all columns which has a width of the minimum size that you desire. This will then enforce your td percentages when the broswer is resized or your iframe is small.

Like so:

<html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title></title> <style> .min500 { width: 500px; height: 1px; } </style> </head> <body> <form id="form1" runat="server"> <table align="center" border="1" cellpadding="0" cellspacing="0" class="loginBg"> <asp:Panel runat="server" ID="pnlLoginIn" style="width:100%;"> <tr> <td colspan="2"> <div class="min500"></div> </td> </tr> <tr> <td style="padding-left:0px;font-family:Verdana;font-size:70%;width:30%;"> Username </td> <td style="padding-right:0px;width:70%;" align="left">&nbsp; <asp:TextBox id="txtUsername" runat="server" Width="90px" /></td> <asp:RequiredFieldValidator ID="rfvUserName" runat="server" ErrorMessage="*" ControlToValidate="txtUsername" ValidationGroup="credentials" Display="Dynamic" /> </tr> </asp:Panel> </table> </form>

I've started to study Android few weeks ago and now I need your help. My task is create off-line map (using OSMDroid and Mobile Atlas Creator), with two markers on it, path between them and some activity after clicking on this markers. I've done map, markers and path. Here is the code (Android 2.3.3):

12430065 0 Fancybox 2 afterClose focus

I've just tried Fancybox 2 and have a problem! In Fancybox 1.3.4 I could trigger a function when fancybox closed, namely to add the focus to the current thumb element (e.g. in a gallery).

It looked this way:

onClosed : function(){ currentArray[currentIndex].focus(); }

However, in Fancybox 2 they deprecated onClosed and there is an other parameter, afterClose, but I couldn't find the variables that store the current thumb element.

Please, help!

37856330 0 How to redirect bindings to "outside" of a XAML control

Let's say I have a ListView with a ContextMenu. I'd like to use it as a separate control called ListViewWithContextMenu. How can I redirect the command bindings from ContextMenu so they're visible in ListViewWithContextMenu?

I have a form on my website, in which I want to submit some data and search a database. The form has a input field, a drop-down menu and a submit button. I want the input field and drop-down to flag/ not submit if the submit button is pressed and nothing is entered. I have looked here: Bootstrap Validator

I would recommend you look at Jade. It is a template engine for node js which can be used to create html pages. It is easy to use and very flexible.

A good tutorial is found here. It shows you how to create a simple Website with Node, Express and Jade and is a good starting Point in my opinion.

To solve your problem with Jade there are several answers in stackoverflow like here.

This basically means that in JS "Aardvark" is considered lesser than "Zoroaster" because JS uses something called Lexicographical Ordering, also known as Dictionary Order because dictionaries also use the same order when listing words.

2497127 0 Validating Application Settings Key Values in Isolated Storage for Windows Phone Applications

I am very new at all this c# Windows Phone programming, so this is most probably a dumb question, but I need to know anywho...

 IsolatedStorageSettings appSettings = IsolatedStorageSettings.ApplicationSettings; if (!appSettings.Contains("isFirstRun")) { firstrunCheckBox.Opacity = 0.5; MessageBox.Show("isFirstRun not found - creating as true"); appSettings.Add("isFirstRun", "true"); appSettings.Save(); firstrunCheckBox.Opacity = 1; firstrunCheckBox.IsChecked = true; } else { if (appSettings["isFirstRun"] == "true") { firstrunCheckBox.Opacity = 1; firstrunCheckBox.IsChecked = true; } else if (appSettings["isFirstRun"] == "false") { firstrunCheckBox.Opacity = 1; firstrunCheckBox.IsChecked = false; } else { firstrunCheckBox.Opacity = 0.5; } }

I am trying to firstly check if there is a specific key in my Application Settings Isolated Storage, and then wish to make a CheckBox appear checked or unchecked depending on if the value for that key is "true" or "false". Also I am defaulting the opacity of the checkbox to 0.5 opacity when no action is taken upon it.

With the code I have, I get the warnings

Possible unintended reference comparison; to get a value comparison, cast the left hand side to type 'string'

Can someone tell me what I am doing wrong. I have explored storing data in an Isolated Storage txt file, and that worked, I am now trying Application Settings, and will finally try to download and store an xml file, as well as create and store user settings into an xml file. I want to try understand all the options open to me, and use which ever runs better and quicker

I would assume you're trying to create member object properties

''represents a class instance of a blog entry''' title = models.CharField(max_length=100) created = models.DateTimeField() body = models.TextField()

which should ideally go into the constructor method under

 def __init__(self): ''represents a class instance of a blog entry''' title = models.CharField(max_length=100) created = models.DateTimeField() body = models.TextField()

19329366 0 How does git checkout know whether to remove a file or leave it alone?

I have some files with "settings" (say, Eclipse *.prefs files) that I don't want to track. They were already being tracked (because I didn't set something up right), but it looked like git rm --cached was how to stop the files from being tracked. I tried this, and now git status lists the files as deleted:, but they're still there in my directory. So far, so good.

Suppose that I use git commit in the current state; it will create a new commit C1 but won't track those files. Suppose that some time later, and after several more commits, and assuming I've made some changes to my settings files, I use git checkout to revert to the commit C1. Will this remove the no-longer-tracked settings files, or just leave them alone? I'm concerned about how Git knows the difference, when checking out an earlier commit, between "this file isn't in the commit so I'm going to remove it", and "this file should be left alone". The fact that Git is reporting the files as deleted: makes me a bit more concerned, I guess, although perhaps that's just inaccurate output.

37257842 0 How shall I populate my RecyclerView asynchronously?

Problem

My RecyclerView displays elements with photos. Every photo is being downloaded from the Internet which may take up to few seconds. Hence, I try to avoid blocking the UI thread and I pass the work to a Handler, however, due to RecyclerView's recycling behavior, it shows the images improperly.

This is how it looks like:

Loads image 1 to list item 1.

Loads image 2 to list item 2.

I scroll down.

Loads image 3 to list item 20.

Loads image 4 to list item 21.

Loads image 4 to list item 20.

Loads image 5 to list item 21.

At the end everything is ok, but during the loading process, RecyclerView recycles the ViewHolders with the wrong images!

My code

mHandler.post(new Runnable() { @Override public void run() { final Uri image = complexFetchingFunction(); activity.runOnUiThread(new Runnable() { @Override public void run() { try { holder.imageView.setImageURI(image); } catch (Exception e) { e.printStackTrace(); } } }); } });

End

Handler works on a separate thread. That's sure. I know all these things happen, because I load the images asynchronously and RecyclerView doesn't like it, but otherwise it's painfully slow.

Does anyone have a solution?

You could press ctrl-z (at least in Windows this works for me) but you probably don't want to do that. This would mean your program could only ever read once from the console. Better would be that you only read a line at a time rather than try to read "the whole file". Then you can just press enter to finish reading. Somthing like this:

Scanner s = new Scanner(System.in); String t = s.nextLine();

13084811 0 Char Array contains null characters before the end

I've got a class project to make a webserver in c++. Everything's been going OK until I got to the point where I needed to host images or pdfs, at which point the files were corrupted. Doing some more digging, I realized that all the corrupted images had null characters before the end.

That brings me to my question. I have a char* which I've read these files to, and I know the length of the file. I'm pretty positive that the entire file is being read in (code below), but I don't know how to print it out or send it. How can I tell C++ that I want to send the first X characters following the char*? (I'm sure the answer is somewhere here or on the web, I just can't seem to phrase my question in the right way to find the answer)

ifstream myfile (path.c_str() , ios::in|ios::binary|ios::ate); ifstream::pos_type size = myfile.tellg(); cout << size << endl; fileSize = (int) size; fileToReturn = new char [size]; myfile.seekg (0, ios::beg); myfile.read (fileToReturn, size); myfile.close(); cout << "file read\n"<< fileToReturn << endl;

For a plain text file, this would output fine. For the PDF, it only prints the first part of the file (the part before the first null character). How do I get it to print out the whole file?

EDIT: To clarify, my end goal is to send this over the web, not re-save the file.

// reply is string with all my headers and everything set. // fileToReturn is my char*, and fileSize is the int with how long it should be char* totalReply = new char [reply.length() + fileSize+1]; strcpy(totalReply, reply.c_str()); strcat(totalReply, fileToReturn); send(client, totalReply, reply.length() + fileSize, 0);

For a much more sophisticated discussion of storing JSON in SQL Server as relational data and extracting it back as JSON please see this wonderful article by Phil Factor (thats the name he goes by), Producing JSON Documents from SQL Server queries via TSQL,https://www.simple-talk.com/sql/t-sql-programming/producing-json-documents-from-sql-server-queries-via-tsql/ .

Be careful about storing JSON as varchar with full text indexes or as xml type (which is not the same as JSON) with xml indexes. There can be severe performance issues when doing inserts on even a million row table so test carefully with realistic, for you, numbers of rows to see if an XML or varchar solution works for you.

If all you are going to do is stuff JSON data into varchars and back again then you should have no problems. Until the latest version of Mongo (3.04 or so) Mongo was not transactional based and one client of mine was always losing data and that caused a world of finger pointing. If the version of Mongo that you are using is not ACID compliant be very, very careful.

I am amending this answer because SQL Server 2016 now supports JSON in a big way. According to Microsoft it was one of the most requested features. Please see the following two articles:

https://msdn.microsoft.com/en-us/library/dn921897.aspx https://blogs.msdn.microsoft.com/jocapc/2015/05/16/json-support-in-sql-server-2016/

Why don't you replace the @PreUpdate/@PrePersist mechanism with a @Version on the lastModified field ? This way all updated entity will have the field set (and only updated ones).

It should make the job as you expect if I understood well your case.

40779020 0 Bootstrap hide and show div based on sidebar menu item clicked

I'm new to bootstrap and still trying to familiarize myself with the available classes that I can use. So, I tried to build a sidebar but I can't get it to show only the target div of the menu item clicked on the sidebar.

In other words, one div at a time and not stack of divs.

To better illustrate, here's a screenshot.

It doesn't replace the current div, instead it just simply shows the div then hides it on button click. This ends up on displaying or hiding one or both of the divs everytime I click on a menu item on the sidebar

dashboard.xhtml

<div class="container-fluid"> <div class="row"> <div class="col-sm-3 col-md-2 sidebar"> <ul class="nav nav-sidebar"> <li class="active"><a href="#">Dashboard <span class="sr-only">(current)</span></a></li> <li><a href="#customer-div" class="btn btn-default" data-toggle="collapse">Customers</a></li> <li><a href="#orders-div" class="btn btn-default" data-toggle="collapse">Orders</a></li> </ul> <ul class="nav nav-sidebar"> <li><a href="">Frames</a></li> <li><a href="">Posters</a></li> <li><a href="">About Us</a></li> <li><a href="">Users</a></li> </ul> </div> <!-- CUSTOMER --> <div id="customer-div" class="well col-xs-8 collapse"> <h1>CUSTOMER</h1> </div> <!-- END OF CUSTOMER DIV --> <!-- ORDERS --> <div id="orders-div" class="well col-xs-8 collapse"> <h1>ORDERS</h1> </div> <!-- END OF ORDERS DIV --> </div> </div>

I want one div to replace the current div on it's container.

I'd appreciate any help.

Thank you.

My mistake was implementing the delegate method:

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath

instead of the one I meant to implement:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

Hence only being called on the second cell being tapped, because that was when the first cell would be de selected. Stupid mistake made with the help of autocomplete. Just a thought for those of you who may wander here not realizing you've made the same mistake too.

There's no generic method that can work with primitives, because primitives can't be a generic type. The closest you could come in pure Java is to overload getArrayList with an int[]...

public static ArrayList<Integer> getArrayList(int[] a){ ArrayList<Integer> retList = new ArrayList<Integer>(); for (int i : a){ retList.add(i); } return retList; }

which will box your int for you. It's not generic, and you'd need a new overload for each primitive array type, but that's the closest solution I can think of.

29560930 0 Misbehaviour of Backstack of activity when activity destroyed

I have two activities; let's say A and B. In activity A there is a broadcast receiver registered that listens for a particular event which will finish activity A. I am registering the broadcast receiver in onCreate(), and destroying it in onDestroy() of activity A.

For simplicity, there is one button in activity B named "Destroy Activity A". When a user clicks on button, activity A should be destroyed.

Normally all of this is running smoothly without any issues,but the problem occurs in following scenarios:

1) Suppose I am in activity B and i press the Home key to move the application to the background then if i use other resource-heavy applications, Android system will kill my application to free memory. Then If I open my application from recent tasks, activity B will be resumed, and it's onCreate(), onResume() etc method will be called. Now I press button to destroy activity A, but activity A has already been destroyed, so activity A's onCreate(), onResume() etc methods will not be called until and unless i go to activity A by pressing the back button. Thus broadcast receiver is not registered to listen for the event.

2) The same problem will arise when user has selected "Don't keep activities" from Developer options in the device's settings.

I have been looking to solve this issue for a long time, but i am unable to find a proper answer. What is the best way to handle this scenario? Is this an Android bug? There should be some solution for this issue.

Please help me.

17626330 0 What's the difference between global var post and get_post?

I use the_posts filter to add an object to each queried post. When access the added object, I get different result by using $post or get_post.
This is the code to attach the object to posts:

add_filter( 'the_posts', 'populate_posts_obj', 10,2 ); function populate_posts_obj( $posts, $query ){ if ( !count( $posts ) || !isset($query->query['post_type']) ) return $posts; if( in_array( $query->query['post_type'], get_valid_grade_types())){ foreach ( $posts as $post ) { if ( $obj = new Gradebook( $post->ID ) ) $post->gradebook = $obj; } } return $posts; }

Then, access the obj via $post, sometimes get the obj, sometimes not (even when it's the same post):

function get_the_gradebook(){ global $post; return isset($post->gradebook) ? $post->gradebook : null; }

Access the obj via get_post(), always get the obj:

function get_the_gradebook(){ global $post; $p = get_post($post->ID); return isset($p->gradebook) ? $p->gradebook : null; }

I can just use the get_post() version, but it would be useful if I know why the difference.

Additional info:

If you ask the reason I attach an obj to each post, I think WordPress may take care of the caching process at the first place. Then, other caching plugins can work on my obj as if working on standard WP posts.

28286290 0 Linux system call time() is returning ((time_t) -14) on error

The man page man 2 time says:

SYNOPSIS #include <time.h> time_t time(time_t *t); RETURN VALUE On success, the value of time in seconds since the Epoch is returned. On error, ((time_t) -1) is returned, and errno is set appropriately. ERRORS EFAULT t points outside your accessible address space.

I've got a simple test set up, trying to coerce an error from that function - should be the most straightforward thing ever:

time_t *ptr = (time_t *) 0xabad1dea; time_t secs = time(ptr); if (secs == ((time_t) -1)) /* Not caught */ exit(EXIT_FAILURE); printf("Number of seconds since the Epoch: %lld\n", secs); printf("It should return ((time_t) -1) on error: %lld\n", (time_t) -1); secs = *ptr; /* This *does* segfault */

For some reason, time() is returning -14 instead of -1 on my system. I'm completely stumped. Baffled, even.

I doubt anyone can reproduce this issue, but does anybody out there know why on earth I might be getting that behaviour? If so, I'm terribly curious!

EDIT: I know time isn't dereferencing the bad pointer I pass it, because that crashes the program. And the man page does say it should return -1 and set errno if the address isn't reachable. EFAULT is 14, but isn't returning -EFAULT not what time() is defined as doing here?

34808035 0 Starting async method as Thread or as Task

I'm new to C#s await/async and currently playing around a bit.

In my scenario I have a simple client-object which has a WebRequest property. The client should send periodically alive-messages over the WebRequests RequestStream. This is the constructor of the client-object:

public Client() { _webRequest = WebRequest.Create("some url"); _webRequest.Method = "POST"; IsRunning = true; // --> how to start the 'async' method (see below) }

and the async alive-sender method

private async void SendAliveMessageAsync() { const string keepAliveMessage = "{\"message\": {\"type\": \"keepalive\"}}"; var seconds = 0; while (IsRunning) { if (seconds % 10 == 0) { await new StreamWriter(_webRequest.GetRequestStream()).WriteLineAsync(keepAliveMessage); } await Task.Delay(1000); seconds++; } }

How should the method be started?

new Thread(SendAliveMessageAsync).Start();

Task.Run(SendAliveMessageAsync); // changing the returning type to Task

await SendAliveMessageAsync(); // fails as of the constructor is not async

My question is more about my personal understanding of await/async which I guess may be wrong in some points.

The third option is throwing

The 'await' operator can only be used in a method or lambda marked with the 'async' modifier

you can do by adding timespan to datetime like,

 TimeSpan timespan = new TimeSpan(03,00,00); DateTime time = DateTime.Today.Add(timespan); string displayTime = time.ToString("hh:mm tt");

instead of 03,00,00 you can directly pass your timespan variable

I would like to interlock an undefined number of divs (as in Pinterest) from this:

to this:

Is it possible with CSS or other stuff?

There is no general and explicit way to constrain vectors. The constraint will have to be enforced as an invariant of your algorithms; whenever you push_back data to one vector, also push it to the other one. (Be sure to keep the vectors private.

29769393 0 Bash rename files with underscore

I have files that are named CULT_2009_BARRIERS_EXP_Linear.dbf
and would like to rename them to CULT_BARRIERS_EXP_Linear.dbf . The files have a date prefixed with them which is always different showing when it was captured. I have tried to replace them with regular expressions. i want to test the string if it contains numbers and then rename. I have used

 if [[ $file =~ [0-9] ]]; then rename -v "s/[0-9]//g" * && rename -v s/[_]_/_/ *;

which partially works. But I would ideally like to have one rename command as it is good practice

I prefer to have NO extra LIBRARY PATHS in Tools Options, in every Delphi version, and to have each project have its own search path.

I prefer to have my settings exist and be the same for all build configurations. To do this, I make sure that I use the root nodes. This is unfortunately not as straightforward in Delphi 2007 since you have a Build = Debug setting and Build = Release setting, and if I remember correctly, there is no ROOT node in Delphi 2007.
For you, in Delphi 2007, you may have to pay special attention to keeping the values in the debug and the release branch the SAME manually as I believe you can't do this automatically in Delphi 2007.
To answer your question there is no need for a full path and generally no need to use $(PROJECTDIR). There is also no need for a full path. You need to use relative paths, like this: ..\Lib\Dir1;..\Lib\Dir2;..\Lib\Dir3 and so on. My goal for using relative paths is to satisfy the desire to check out code and build it anywhere. Code which can only be built when checked out to a certain directory (C:\YOURAPP) is sloppy, dare I say downright lazy, as well as impractical, and also so sadly common that you might think it was a best practice. Such sloppy no-effort codebases prevent proper continuous integration practices, prevents having multiple working copies that are at different branches or major versions, and so on, and is often worked around by keeping all the code barely building in some kind of virtual machine. Nobody even knows how to set their code up, so they shove it in a VM and let the mess moulder.
When you absolutely CAN NOT use relative paths such as when you don't know where the other stuff is, you should set your OWN in house root folder variable, if your company was called ACME, I would call it ACMEROOT, and I would set it up myself. At my current company we have such a root variable we call it PS because our product's initial capitals are P and S. Then we use $(PS) similar to the way you see $(BDS) used in the library path.
Sometimes I find it useful to have an external tool that I have written that will set up the environment variables for me, directly writing to the IDE the environment variables that I want, and I have a practice of checking out code from version control and running this tool to set up my environment. It so happens I can now check the code onto a fresh computer and run it without any manual effort to set up packages, install components, configure library paths, or projects, and everything just builds. Unfortunately the IDE does not provide everything you need for such a practice, but there are a variety of third party tools that can provide you with a portable clean easy to build codebase.

No, you can't change the behavior of IntelliSense that way.

The issue you're facing is actually a code smell regarding your class design.

If you have certain methods that aren't of any use unless a given constructor was used, you should probably split the class so that the different functionality is clearly delineated.

It might make sense to have a base class of the common behavior and subclasses for each of the different types of constructors. This would effectively do what you're asking for, and follow proper object-oriented design.

my libraries are in SVN, and I usually check them out for (branch them into) a project at ../libraries relative to the project. This keeps the scope of the includes dirs small and to the point.
In the real source (.pas), paths are totally forbidden.
no project related paths in global delphi searchpath (only per project, or they are truly universally shared sources/components)
I hate poluting source with hardcoded paths, so I usually have only a few units in the project, always with relative paths. Not the VSS w:\ drive substitutes hack please! Typically these are the units that pull in framework parts or are needed due to visual inheritance or form initialization.
Unfortunately, relative paths can be dangerous with Delphi, because they are relative to the working directory, which can change according to Delphi dialogs (e.g. Open). The solution is simple, have an include file with an unique name in the main project.

5747980 0 Create Single Event ICS file with Expression Engine

I'm trying to create an ICAL file based on a single entry inside an Expression Engine channel but my methods of accomplishing this are failing. I've tried the following:

Passing the entry ID into a new template (which creates the file) but using the $_GET function seems to be frowned upon in EE
Creating a session variable with the entry ID but there seems to be no way of adding this variable to the {exp} query:

{exp:channel:entries channel="gallery" entry_id="MY_PHP_VARIABLE" limit="1" show_future_entries="yes"}

I haven't tried just making a flat file each time the single entry page is accessed with fwrite() and linking directly to it, but that seems like a costly move.

Is there a way with PHP to make the file when I click a button? Maybe firing off a function written in the page so I don't need to pass or detect the entry_id?

DefaultTableCellRenderer inherit from JLabel (that inherit from JComponent). So you can change the JLabel properties within getTableCellRendererComponent.

For example :

ImageIcon icon = new ImageIcon(getClass().getResource("images/moon.gif"));// prepared before public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { setText((String)value); setIcon(icon); return this; }

setText come from the super JLabel class and setIcon from the super JComponent class.

Almost all DefaultTableCellRenderer methods override method from these classes.

Why not try something like this:

foreach (var file in System.IO.Directory.GetFiles(k)) { zip.AddFile(file); }

To get the directories and files to an unlimited depth, combine that with a recursion method based on System.IO.Directory.GetDirectories("path") - should be pretty straightforward methinks.

In a nutshell:

LINQ is a quering technology (Language Integrated Query). LINQ makes extensive use of lambda's as arguments to standard query operator methods such as the Where clause.

A lambda expression is an anonymous function that contain expressions and statements. It is completely separate and distinct from LINQ.

12844095 0 How do I use Bash to create a copy of a file with an extra suffix before the extension?

This title is a little confusing, so let me break it down. Basically I have a full directory of files with various names and extensions:

MainDirectory/ image_1.png foobar.jpeg myFile.txt

For an iPad app, I need to create copies of these with the suffix @2X appended to the end of all of these file names, before the extension - so I would end up with this:

MainDirectory/ image_1.png image_1@2X.png foobar.jpeg foobar@2X.jpeg myFile.txt myFile@2X.txt

Instead of changing the file names one at a time by hand, I want to create a script to take care of it for me. I currently have the following, but it does not work as expected:

#!/bin/bash FILE_DIR=. #if there is an argument, use that as the files directory. Otherwise, use . if [ $# -eq 1 ] then $FILE_DIR=$1 fi for f in $FILE_DIR/* do echo "Processing $f" filename=$(basename "$fullfile") extension="${filename##*.}" filename="${filename%.*}" newFileName=$(echo -n $filename; echo -n -@2X; echo -n $extension) echo Creating $newFileName cp $f newFileName done exit 0

I also want to keep this to pure bash, and not rely on os-specific calls. What am I doing wrong? What can I change or what code will work, in order to do what I need?

a few notes / pointers about doing this in python.

Use the bisect module to keep your result array in order to easily spot potential non-uniques. This is helpful even if v1 is already sorted (e.g. name and enemy will collide after disenvoweling)
Disemvoweling can be achieved by simple calling .translate(None, "aeiouyAEIOUY") on the string.
In case of duplicates you could try to resolve the collisions first by lowercasing all results and using swapcase as "bitmask", i.e. multiple occurences of aaa become ["aaa", "aaA", "aAa", "aAA"] etc. and if this is not enough "incrementing" characters starting from the end, until a non-colliding identifier is found, eg. ["aa"]*7 would become ["aa", "aA", "Aa", "AA", "ab", "aB", "Ab"]

The issue here is: You are using your ID for the elements in a while-loop. So you end up having multiple IDs in your document, which is invalid. So jQuery will always get the first one.

I would suggest the following:

get rid of the inline onClick-handler and use a proper event-handler
use a class- selector instead of ID
save your usrid-value to the element your are clicking on

Your code would be as follows:

HTML

<input type='text' class='hidden' name='usridl' id='usrid' value='".$staff_data['id']."' /> <a href='javascript:void(0);' class='delete-row' id='dltbutton' name='btn-dlt' data-usrid='".$staff_data['id']."'><i class='fa fa-trash red'></i></a>

for is indeed mostly just sugar for each (Try using for on a non enumerable object - it should complain about it not responding to each). It differs in that it doesn't create block scope.

How each is implemented depends on the object you are calling it on (each is the method on which all of Enumerable is built). In any case the block will be called with a succession of values. Reassigning the block variable that is yielded does nothing - upon the next iteration i is set to whatever the next value should be.

You can skip with next or terminate with break but that's it as far as controlling the iteration goes - there's no way of saying "jump forwards 3"

I don't like static data members much, the problem of initialization being foremost.

Whenever I have to do significant processing, I cheat and use a local static instead:

class MyClass { public: static const SomeOtherClass& myVariable(); }; const SomeOtherClass& MyClass::myVariable() { static const SomeOtherClass MyVariable(someOtherFunction()); return MyVariable; }

This way, the exception will be throw only on first use, and yet the object will be const.

This is quite a powerful idiom to delay execution. It had a little overhead (basically the compiler checks a flag each time it enters the method), but better worry about correctness first ;)

If this is called from multiple threads:

if your compiler handles it, fine
if your compiler does not, you may be able to use local thread storage (it's const anyway)
you could use boost::once in the Boost.Threads library
since it's const, you may not care if it's initialized multiple times, unless someOtherFunction does not support parallel execution (beware of resources)

Guideline: only use static or global variables instantiation for simple objects (that cannot throw), otherwise use local static variables to delay execution until you can catch the resulting exceptions.

You can combine the Where and the FirstOrDefault, as FirstOrDefault allows you to specify a predicate. This will save you going through the entire list only to take the first, if it's there. Then you use the null coalescing operator ??, which will only evaluate the right side if the left side is null:

WordForm wordForm = db.WordForms .FirstOrDefault(w => w.Definition == result.definition) ?? addWordForm(result, word);

Unfortunately, it is illegal to reference a variable/param in a match pattern in XSLT 1.0. However, you can reference your $lang parameter any time you apply templates. So, for example, in the root template (i.e. a template that matches / or some other sufficiently top-level node), you could specify that you only want to apply templates to elements that have an xml:lang attribute equal to the value of your param (or no xml:lang at all):

<xsl:apply-templates select="*[not(@xml:lang) or @xml:lang=$lang]" />

This won't process any undesired elements and no other templates need to specify the language to match.

There are somethings that can help a lot here. First opening a second window can be a painful experience both for the user and the programmer. Unless you have an absolute need I would recommend manipulating the current window's DOM to display a popup instead.

Next if you can use DOM methods to change the page contents. document.write comes with a lot of problems which in your case are not apparent. Mainly it can erase you current DOM. You don't notice this in your example because the new window is blank so rewriting it is incidental.

Finally your use of allInfo is a quirky way to reference a global variable. It is not easily understood that this is happening from the style of code. In fact any linter will throw an error for your use of the global and will case an error if you declare "use strict" in your functions. Best to learn the good coding practises way.

Since we will want to interact with a variable (allInfo) in your case we should encapsulate the value in an object. This object can hold the state of that reference and offer some abstracted interactions with it. By doing so you avoid polluting the global name space and allow you to swap out your implementation without having to rewrite the parts of your program that depend on it.

// Our welcome window object function WelcomeWindow() { // save a reference to the content of your new window // to be printed when ready. (Lazy execution) this.innerHTML = ''; } WelcomeWindow.prototype.open = function() { this.win = window.open("", "displayWindow"); return this; }; WelcomeWindow.prototype.close = function() { this.win.close(); return this; }; WelcomeWindow.prototype.write = function(html) { this.innerHTML += '' + html; return this; }; WelcomeWindow.prototype.render = function() { if (!this.win) { throw new Error("window has not been opened yet."); } this.win.open(); this.win.write('<!doctype html><html><head><link rel="stylesheet" type="text/css" href="mystyle_invite.css"><title>Resume</title><meta charset="utf-8"> </head><body>'); this.win.write(this.innerHTML); this.win.write('</body></html>'); this.win.close(); return this; };

This allows us to declaratively manipulate the window before it is opened. For example if we want to add the name to the window:

function NameField(id) { this.element = document.getElementById(id); } NameField.prototype.toString = function() { var name = this.element.value; switch (name) { case 'Michael': return 'Mr. Michael'; case 'Sam': return 'Mrs. Sam'; default: return 'Sir ' + name; } }; NameField.prototype.toHtml = function() { return '<strong>' + this.toString() + '</strong>'; };

Linking it together using code instead because adding events into the DOM only confuses the separation of markup and code.

window.onload = function() { var form = document.getElementById('infoForm'); form.onsubmit = function(e) { e.preventDefault(); var name = new NameField('firstName'); new WelcomWindow() .write(name.toHtml()) .open() .render(); return false; }; };

I usually pronounce it as "lambda x to y". This is very short and matches how you would type it in TeX: \lambda x \to y. (As a cute note, I have a TeX input mode in my editor, so I could type the above to get λ x → y. :P)

That said, I'm sure that everyone would understand you if you said "lambda x dot y"--most people are at least familiar with that notation and the it's very easy to guess what you mean from context.

I've never heard anybody say "goes to", however.

You can't do it with a LINQ join, basically - LINQ only directly supports equijoins.

You can however do:

var query = from trip in db.Trips from driver in db.Drivers where trip.DriverId == driver.DriverId || trip.CoDriverId == driver.DriverId select new { driver.DriverId, trip.TripId };

That may well end up with the same join in the converted SQL.

It is hard to help unless you post a bit more detail and some code. Without that here are some suggestions that might help.

You will need a submit button or some JavaScript to post the form inside the partial. If you have another form on the page which you are submitting, it will not include data from other forms and inputs on the page.

Also to form has to post back to a controller action, a partial just a helper to render a view inside another view.

I wait for response from server for 1 second and check for it in console but [...]

Changing the model manually (click the button using your mouse) instead of programmatically (click()) is the crucial part here.

I assume you do not return the final model from your server, as Backbone update's your model with that data.

See section 53 and

if (options.wait) { if (attrs && !this._validate(attrs, options)) return false; current = _.clone(this.attributes); }

section 55

options.success = function(resp, status, xhr) { done = true; var serverAttrs = model.parse(resp); if (options.wait) serverAttrs = _.extend(attrs || {}, serverAttrs); if (!model.set(serverAttrs, options)) return false; if (success) success(model, resp, options); };

of the Backbone.js documentation. Especially these lines:

var serverAttrs = model.parse(resp); (Parse model data from response)

if (!model.set(serverAttrs, options)) return false; (Update your model's attributes)

When your first code (the one where you click() the buttons) runs, it increases your models attribute and loggs it before the server returns. Thats

Note: using the wait option or a setTimeout() in your 2nd press of button three in your first code would equal the behaviour.

But what you want, is to return a valid model from your server (after persisting it).

Off topic tip: you should not bind your model and your view in the models initializer or constructor as it would couple them too tight and they wouldn't be interchangable. (For this question, it is certainly acceptable. ;)

You can debug with the library installed on your host, provided the debugging machine is also the development machine. In that case, you use set sysroot instead of set sysroot-on-target. For example :

set sysroot /home/username/.../rootfs/

where /home/username/.../rootfs/ contains a copy of your target filesystem

I think you should also specify / instead of /lib

No. You see, switch statements are for comparing many different values of the same type for a match to a certain other value.

A switch statement is formed like this:

switch (var){ case 5: //var == 5 break; case 10: //var == 10 break; default: //var is not 5 nor 10 break; }

Which only allows comparisons to constant values, thus making it useless towards data types. An if statement is a much better choice for this purpose, as the only solution for using a switch statement (getting the instance name and comparing it in that format) would be writing too much extra (and unnecessary) code that is not needed and can more easily be done in another manner.

35579637 0 Gap in auto-increment IDs on Heroku Postgres

I've got a Ruby web app running on Heroku with a Postgres database. I've noticed the auto-incremented IDs have a gap in them around the time that the Postgres database was under "maintenance" by Heroku.

The gap is a one-time thing, and then the IDs increment by 1 again. Like so:

ID | Created at | 2959 | 2016-02-14 21:07:05.149797 | 2960 | 2016-02-14 21:15:05.03284 | 2961 | 2016-02-14 22:59:19.634962 | 2994 | 2016-02-15 09:25:30.969881 | 2995 | 2016-02-15 09:44:38.49678 | 2996 | 2016-02-15 09:51:00.282624 |

The maintenance by Heroku happened in between the two records (2961 and 2994) being created, at 2016-02-15 04:00:00.

I've seen an explanation that a failed transaction will result in an ID being skipped over on the next successful commit, but I can't see anything in the application logs to indicate that any records were being created around the time.

679976 0 Large dataset (SQL to C#), long load time fix

I have a site I'm building, it's an application that creates mail merges (more or less...) based on a couple of user preferences. It can generate Cartesian joins worth of data without a problem, but in comes the needs of enterprise to make life a bit more difficult...

I have to build the application so that, after verifying zip codes of remote employees, it creates emails to media targets based on how far from that employee the media target is. Let's say for instance employees are well known volunteers where they work. The enterprise wants to email media within a 5 mile radius of these employees a message about the work the employee is doing. This is where things get messy... I have several choices here, which I will outline the attempts and the failures:

The largest radius is 20 miles. I create a database table that holds records of every zip code in the US, joined to every zip code within 20 miles of that zip code. The dataset looks something like (The names are different this is for the sake of argument):
[SourceZip] | [City] | [State] | [CloseZip] | [City] | [State] | [Distance]
Fails: As an example, NY has 350k records from the above dataset (and other states are worse!). Average load time on that page? 6 minutes... Not happening. I verified this by setting breakpoints, it is during the dataadapter.fill() stage that the disconnect occurs.
(This one was never implemented due to a logistics problem) I make a database connection for each employee zip to media target zips with a distance of x or less. Except that the source files and the media targets combined can reach upwards of 34k individualized emails. 34k DB connections? even if I could devise a way to reuse zip code searches, I did some test checks in the DB and found that there are 500 distinct zip codes in NY where employees worked. 500 db connections? I doubt that would work but I could be surprised.
My latest scheme to get around the problem is in that hoping the web server runs a better game then the .net dataset object by getting a new dataset looks like:
[zip] | [longitude] | [latitude]
Then doing a distance formula to figure out if the data works. This relies heavily on the processors on the web server. Is this a worthwhile gamble, or will I find the same load time damage on this attempt as well?

Is there a better way?

I appreciate any input, even if it confirms my fears that this project just might not work.

Additional notes: I don't have control of the server, and I'm running SQL2k :(. I'm programming the site in visual studio 2005, framework 2.0. Might get upgraded to SQL2005 and VS2008 within the next few months though.

You need to use System.Messaging.Message.CorrelationId property.

Gets or sets the message identifier used by acknowledgment, report, and response messages to reference the original message.

Source: https://msdn.microsoft.com/en-us/library/system.messaging.message.correlationid(v=vs.110).aspx

var msgToSend = new Message(); // ... set message props including admin queue var targetQueue = new MessageQueue(...); targetQueue.Send(msgToSend); // Read acknowledgment var adminQueue = new MessageQueue(ackPath); var msgAck = adminQueue.ReceiveByCorrelationId(msgToSend.Id, new TimeSpan(0, 0, 2)); if (msgAck) { return msgAck.Acknowledgment; }

There is PeekByCorrelationId method too, or overload forms of ReceiveByCorrelationId which you should check for more information.

First, you are right, you get value of 0, because the screen didn't draw yet when you try to get the button width.

As I see it, the only possibility to do it like you want, is to give them pre defind value in the XML file.

For example:

 <Button android:id="@+id/b1" android:layout_width="25dip" android:layout_height="25dip" android:gravity="center" />

Set the width and height programmally:

DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics); btnWidth = metrics.heightPixels/3 - 50;//gap btnHeight = btnWidth; Button b1 = (Button) findViewById(R.id.b1); b1.setHeight(btnWidth); b1.setWidth(btnWidth);

If Right(Field2, 3) = "A-1" Or _ Right(Field2, 3) = "A-2" Or _ Right(Field2, 3) = "B-1" Or _ Right(Field2, 3) = "B-2" Or _ Right(Field2, 3) = "C-1" Or _ Right(Field2, 3) = "C-2" Or _ Right(Field2, 3) = "D-1" Or _ Right(Field2, 3) = "D-2" Or _ Right(Field2, 3) = "D-3" Then Cells(i, 50).Value = "OtherPrtnrs /Dcrs & Dept heads" End If

Or better still... this

Select Case Right(Field2, 3) Case "A-1","A-2","B-1","B-2","C-1","C-2","D-1","D-2","D-3" Cells(i, 50).Value = "OtherPrtnrs /Dcrs & Dept heads" End Select

Note: I am assuming that i is a valid row number

Explanation:

When comparing using an If statement, you cannot say If A = B or C. You are supposed to compare is separately. If A = B or A = C Then. Here each OR is its own Boolean statement i.e it will be evaluated separately.

When you have multiple such comparisons, it is better to use a Select Statement as shown in the example above.

var latLong = place.geometry.location; /** latLong will have { "lat" : -33.8669710, "lng" : 151.1958750 } */

Most likes your place may not have this geometry property in which case, you have to fire new query using place_id(deprecated) or reference (preferred).

reference contains a unique token that you can use to retrieve additional information.

A Place Details request is an HTTP URL of the following form:

https://maps.googleapis.com/maps/api/place/details/output?parameters

Short Answer

Despite the presence of a redirect parameter, the access token will generate a standard 200 response, not a 301 redirect. Depending on how you issue and handle the request/response, you can preserve your state.

Convert Integral context to type

To begin with we will make a class that will try to capture information from the context of a type (whether there's an Integral instance) and convert it into a type which we can match on. This requires the FunctionalDependencies extension to say that the flag can be uniquely determined from the type a. It also requires MultiParamTypeClasses.

class IsIntegral a flag | a -> flag

We'll make two types to use for the flag type to represent when a type does (HTrue) or doesn't (HFalse) have an Integral instance. This uses the EmptyDataDecls extension.

data HTrue data HFalse

We'll provide a default - when there isn't an IsIntegral instance for a that forces flag to be something other than HFalse we provide an instance that says it's HFalse. This requires the TypeFamilies, FlexibleInstances, and UndecidableInstances extensions.

instance (flag ~ HFalse) => IsIntegral a flag

What we'd really like to do is say that every a with an Integral a instance has an IsIntegral a HTrue instance. Unfortunately, if we add an instance (Integral a) => IsIntegral a HTrue instance we will be in the same situation Christian described. This second instance will be used by preference, and when the Integral constraint is encountered it will be added to the context with no backtracking. Instead we will need to list all the Integral types ourselves. This is where we fall short of our goal. (I'm skipping the base Integral types from System.Posix.Types since they aren't defined equally on all platforms).

import Data.Int import Data.Word import Foreign.C.Types import Foreign.Ptr instance IsIntegral Int HTrue instance IsIntegral Int8 HTrue instance IsIntegral Int16 HTrue instance IsIntegral Int32 HTrue instance IsIntegral Int64 HTrue instance IsIntegral Integer HTrue instance IsIntegral Word HTrue instance IsIntegral Word8 HTrue instance IsIntegral Word16 HTrue instance IsIntegral Word32 HTrue instance IsIntegral Word64 HTrue instance IsIntegral CUIntMax HTrue instance IsIntegral CIntMax HTrue instance IsIntegral CUIntPtr HTrue instance IsIntegral CIntPtr HTrue instance IsIntegral CSigAtomic HTrue instance IsIntegral CWchar HTrue instance IsIntegral CSize HTrue instance IsIntegral CPtrdiff HTrue instance IsIntegral CULLong HTrue instance IsIntegral CLLong HTrue instance IsIntegral CULong HTrue instance IsIntegral CLong HTrue instance IsIntegral CUInt HTrue instance IsIntegral CInt HTrue instance IsIntegral CUShort HTrue instance IsIntegral CShort HTrue instance IsIntegral CUChar HTrue instance IsIntegral CSChar HTrue instance IsIntegral CChar HTrue instance IsIntegral IntPtr HTrue instance IsIntegral WordPtr HTrue

Matching on IsIntegral

Our end goal is to be able to provide appropriate instances for the following class

class (Num a, Num b) => Power a b where pow :: a -> b -> a

We want to match on types to choose which code to use. We'll make a class with an extra type to hold the flag for whether b is an Integral type. The extra argument to pow' lets type inference choose the correct pow' to use.

class (Num a, Num b) => Power' flag a b where pow' :: flag -> a -> b -> a

Now we'll write two instances, one for when b is Integral and one for when it isn't. When b isn't Integral, we can only provide an instance when a and b are the same.

instance (Num a, Integral b) => Power' HTrue a b where pow' _ = (^) instance (Floating a, a ~ b) => Power' HFalse a b where pow' _ = (**)

Now, whenever we can determine if b is Integral with IsIntegral and can provide a Power' instance for that result, we can provide the Power instance which was our goal. This requires the ScopedTypeVariables extension to get the correct type for the extra argument to pow'

instance (IsIntegral b flag, Power' flag a b) => Power a b where pow = pow' (undefined::flag)

Actually using these definitions requires the OverlappingInstances extension.

main = do print (pow 7 (7 :: Int)) print (pow 8.3 (7 :: Int)) print (pow 1.2 (1.2 :: Double)) print (pow 7 (7 :: Double))

You can read another explanation of how to use FunctionalDependencies or TypeFamilies to avoid overlap in overlapping instances in the Advanced Overlap article on HaskellWiki.

13480990 0 linkout failing with conflicting JSESSIONID

I have an issue with the linkout of my application (say App2) on another application (say App1).

Both are web applications and so both are creating there own JSESSION IDs. The linkout opens in a pop up and single sign on works (siteminder passing the sm user cookie), but as soon as I perform any transaction on the linked application I am thrown out stating the session is either timed out or invalid.

I looked at the cookies present on the browser and found that both the JSESSION IDs are present. The only difference is in the domain scope of both the JSESSION IDs. App1 application has domain scope of say abc.com whereas App2 has app2.abc.com

I tried changing the name of the JSESSION ID cookie of App2 but the application did not work with the renamed JSESSION cookie.

Any suggestion on how can I fix this ?

Note : The environment for App2 is was5

Although, moving the code to change colour inside the event handler will work, I'd suggest to use classList API.

Updated Fiddle

Create a CSS class to set the background color to blue and toggle this class when the box is clicked.

classList.toggle('className') will add the class if it is not already added on the element otherwise it'll remove the class.

document.getElementById("box").addEventListener("click", function() { document.getElementById('circle').classList.toggle('blue'); });

#box { width: 50px; height: 50px; position: absolute; bottom: 0; right: 0; background-color: red; } #circle { width: 50px; height: 50px; background: orange; border-radius: 50px; position: absolute; top: 50%; left: 50%; } #circle.blue { background: blue; }

For my self-education purposes, I would like to investigate the code of a complex Ruby On Rails (preferably 3) business application(s) so that I can get the feel of how to do things in the real world with Rails.

Something like Real-estate systems must be complex enough. Or maybe in the government area (which is always complex by definition :) ).

So I cant find this is a duplicate video or not and if it is duplicate then what is the main video. Means the video details of main video from which it is compared as duplicate.

Please help me to find this is a duplicate video or not?

Do I understand it correctly? You want to invoke something like...

postUser(user); postFile(myFile);

and in the client, to process the two different requests in some stateful manner(the receiver is supposed to know that ).

@Post public void userPost(String name) { User.getInstance().addUser(name); } @Post public void filePost(File file) { //processing the file, ONLY IF the userPost method is already invoked }

Instead, can you encapsulate the two requests in one(one request with two parameters). Something like

 postUserFile(user,file);

And in the request reciever...

@Post public void nameFilePost(String name, File file) { userPost(name); filePost(file) }

I don't recognize the framework which you are using, but in JAX-RS the method will looks something like this

@PATH("/yourPath/") public class YourClassNameHere{ @POST public void nameFilePost(@QueryParam("name") String name, @QueryParam("file") File file) { userPost(name); filePost(file) } }

One last thing: Don't use Singletons, they are global variables, and therefore bad. Why global variables are bad.

Your problem is that you are creating a local variable in the first function and are referring to it in the second function which does not exist. if you make the icon variable global, everything will work fine.

so your code may look like this:

var icon; $('li.social-list').hover( function(){ icon = $(this).html(); $(this).stop().animate({ width: "100px"}, 1000).text('Facebook'); }, function(){ $(this).stop().animate({ width: "50px"}, 1000).html(icon); } );

Update:

So here is the new code, which you should have two texts or one text and one image for each item and display one of them at a time:

HTML:

<div id="social-slide"> <ul> <li class="social-list"><a><i class="fa fa-facebook fa-2x"><span class="text1">1</span><span class="text2" style="display:none;">facebook</span></i></a></li> <li class="social-list"><a><i class="fa fa-twitter fa-2x"><span class="text1">2</span><span class="text2" style="display:none;">twitter</span></i></a></li> <li class="social-list"><a><i class="fa fa-instagram fa-2x"><span class="text1">3</span><span class="text2" style="display:none;">linkedin</span></i></a></li> <li class="activate"><a><i class="fa fa-bars fa-2x">click</i></a></li> </ul> </div>

JS:

$('li.social-list').hover( function(){ $(this).stop().animate({ width: "100px"}, 1000); $(this).find(".text1").hide(); $(this).find(".text2").show(); }, function(){ $(this).stop().animate({ width: "50px"}, 1000); $(this).find(".text2").hide(); $(this).find(".text1").show(); } );

I think you can get the idea from this sample code.

Hope it helps you

Here is a nasty, hacky, quick-fix solution which will stop the nasty cropping by resizing Swing's own icons to 80%.

In main, add this:

String[] iconOpts = {"OptionPane.errorIcon", "OptionPane.informationIcon", "OptionPane.warningIcon", "OptionPane.questionIcon"}; for (String key : iconOpts) { ImageIcon icon = (ImageIcon) UIManager.get(key); Image img = icon.getImage(); BufferedImage bi = new BufferedImage( img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_ARGB); java.awt.Graphics g = bi.createGraphics(); g.drawImage(img, 0, 0, (int) (img.getWidth(null) * 0.8), (int) (img.getHeight(null) * 0.8), null); ImageIcon newIcon = new ImageIcon(bi); UIManager.put(key, newIcon); }

You might want to first check whether this is actually required - Windows 8/10 defaults to 125% but some people will switch it back to 100%. I haven't found an elegant way to do this, but something along these lines will give you an idea:

java.awt.Font font = (java.awt.Font) UIManager.get("Label.font"); if (font.getSize() != 11) { //resize icons in here }

36063051 0 nginx location match on ssl_client_verify

I'm trying to setup nginx in order to match certain URL on server where conditional access is granted (i.e. only those with valid client certificate are allowed to access this area).

Right now, simple location block works fine preventing access to unauthorized users:

location ~ ^/protected/ticketing { if ($ssl_client_verify != SUCCESS) { return 401; } #need treatment of php files here after SUCCESS = $ssl_client_verify ?! }

So no one can access /protected/ticketing/anyThingHere

BUT. When you actually present a valid certificate, and this return 401 does not trigger, /protected/ticketing/index.php is not parsed by an upstream FPM server but instead is presented for download (i.e. content disposition is set to default octet stream).

Is there an elegant way of doing this?

My upstream is defined as:

upstream backend { server unix:/var/run/php5-fpm.sock; }

PHP handler location block:

location ~ [^/]\.php(/|$) { fastcgi_split_path_info ^(.+?\.php)(/.*)$; if (!-f $document_root$fastcgi_script_name){return 404;} fastcgi_pass backend; #pass request to the upstream fastcgi_index index.php; include fastcgi_params; }

FYI, I was able to customize the watch face, using the extension code you provided. No problem there.

If you notice the bundle id in the crash log error, the system is reporting a problem with the watchkit app (which contains the watchkit extension).

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Application is required. bundleID: ql.ManaEU.watchkitapp ...

You'll need to track down what's wrong with the watchkit bundle. The first place to start would be the Xcode watchkit app build target log. If there are no errors or warnings there, check the iPhone and Apple Watch console logs.

If that doesn't point you to the problem, check the Info.plist to make sure those values are valid, and the required keys are present. Also check the watchkit app target build settings.

You should be able to use the Version Editor to compare the Xcode project against its initial commit, to see if something was inadvertently changed or deleted.

You can do it like this (the ASCII codes are in order with the alphabet):

function check_str_for_sequences($str, $min = 3) { $last_char_code = -1; $total_correct = 0; $str = strtolower($str); for($i = 0; $i < strlen($str); $i++) { //next letter in the alphabet from last char? if(ord($str[$i]) == ($last_char_code + 1)) { $total_correct++; //min sequence reached? if($total_correct >= ($min - 1)) { return TRUE; } } else { $total_correct = 0; } $last_char_code = ord($str[$i]); } return FALSE; }

Usage:

$test = 'Lorem ipsum dolor abcsit amet'; echo '----->' . check_str_for_alpha($test); // ----->1

Ti.require uses the CommonJS specification. Although files accessed via Ti.require have access to the Ti namespace, they do not have access to the Global namespace - any variables or functions you have declared in the main program. Ti.include files do have access to the global space and can modify or add to it. Ti.require is preferred, but not always practical. See https://wiki.appcelerator.org/display/guides/CommonJS+Modules+in+Titanium for information on the Ti.require function and https://wiki.appcelerator.org/display/guides/Mobile+Best+Practices for more best practices.

32721816 0 Variable-Less String reverse

In a recent interview, I was asked a very simple question to reverse a string (not just print) without any extra variable and any in-built function. The closest I could think of is:

#include<stdio.h> #include<string.h> int main() { char ch[100]; scanf("%s",&ch); int i=0; while(i<strlen(ch)/2) { ch[i]=ch[strlen(ch)-1-i]+ch[i]; ch[strlen(ch)-1-i]=ch[i]-ch[strlen(ch)-1-i]; ch[i]=ch[i]-ch[strlen(ch)-1-i]; i++; } printf("%s",ch); return 0; }

My solution was rejected as I used variable i. How this is even possible without using a counter variable? Is there any other method to solve this?

EDIT

These were the exact words of question(nothing more or less):

Reverse a string without using any variable or inbuilt functions in C.

38256774 0 Is a default-generated constructor not required to construct all base classes?

I've come across a case in which type-safe c++ produces non-matching ctor/dtors. The following code generates two constructors for A. The default constructor also constructs its base (B), but the default-generated copy/move ctor does not construct B. Later, it destroys B, so we get non-matching ctor/dtor.

I've tried this with gcc and clang and both fail. In the gcc bug report forum they suggested this isn't a gcc problem. I may be missing something, but isn't there something odd when type-safe code results in a dtor call for a class that hasn't been constructed?

Program output:

B() -> INSERT: 0x7fff55398b2f ~B() -> ERASE: 0x7fff55398b2f ~B() -> ERASE: 0x7fff55398b40 // <- unmatched dtor call Assertion failed: (!all.empty()), function ~B, file gcc_bug.c, line 20.

Code follows:

#include <set> #include <iostream> #include <cstdint> #include <cassert> #include <experimental/optional> std::set<std::uintptr_t> all; struct B { B() { std::cerr << "B() -> INSERT: " << this << "\n"; all.insert((std::uintptr_t)this); } ~B() { std::cerr << "~B() -> ERASE: " << this << "\n"; assert(!all.empty()); // FAILS assert(all.find((std::uintptr_t)this) != all.end()); // FAILS all.erase((std::uintptr_t)this); } }; struct A : B {}; static std::experimental::optional<A> f() { A a; return a; } int main() { auto a = f(); return 0; }

The issue is You are Reading from Clients Input and Writing to Clients Output. Basically you are sending whatever client sends back just a Ping Server.

ServerHandler.java

 while((msg = reader.readLine()) != null) { write.write(msg); }

This combined with you initializing the Socket at the Client constructor causes your UI to freeze.

Client.java

 s = new Socket("localhost", 6633); reader = new BufferedReader(new InputStreamReader(s.getInputStream())); write = new PrintWriter(new OutputStreamWriter(s.getOutputStream()));

And right below,

 while ((msg = reader.readLine()) != null) { display(msg); }

Deque is ADT and it could be implemented by linked list or Arrays as data structures. Your answer depends upon the type of data structure being used to store elements.and also I would suggest you to implement a peek operation and it would give you a reference of an element for edit propose .peek operation could be used by other high-level operations like delete/contains etc.

You don't need to add 'return' into the onClick content,just use the checkHost('test').That is OK

As for running the samples,

I downloaded the github repository facebook-sdk-master and then imported it into my project. Then I changed the application name of the samples and set their app_id to my app_id. Now I am able to run them.

9575854 0 MySQL insert NULL value after getting value with $_REQUEST

I have input fields, but if the users leave it blank, i want to insert a null value to my database.

I request values like this:

$val1 = htmlspecialchars($_REQUEST["val"], ENT_QUOTES);

And then insert them to the DB:

INSERT INTO `table` ( `val1` , `val2` , `val3`) VALUES ('$val1', '$val2', '$val3');

I have tried removing the ' around val1, val2, val3 - but then nothing gets inserted into the DB if there is no value. I have also tried something like this:

if (!empty($val1)) { $val1 = "'".$val1."'"; } else { $val1 = NULL;}

And then without the ' around the values - still no insert to the DB

I have experienced this error many times and the solution for me was to increase the apache binary (apache.exe or httpd.exe) stack size. You will need the Visual studio to do that, but you can use the trial version, as I did. You don't even need to turn it on. The command is:

C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64>editbin /STACK:8000000 "c:\Program Files (x86)\WAMP\apache\bin\apache.exe"

Change the paths above according to your environment of course.

In the Visual studio directory VC/binary/ there are several utilities by the name editbin.exe. Use the one suitable for you platform or try them one by one, until it works (as I did).

No, you are misunderstanding how that method works. componentsSeparatedByString: doesn't use the individual characters in the passed string, it uses the entire string. Your separator is the three-character sequence [,]. A string like @"pecan[,]pie" uses this separator, but @"1[0,5]" does not. The similar method componentsSeparatedByCharactersInSet: will do what you are expecting:

[string componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"[,]"]];

If you want to pull digits out of strings and get their numerical values, you may want to look at NSScanner.

Concatenate them like this:

Response.Redirect("Default2.aspx?adi=" + adi + "&soyadi=" + soyadi);

When passing query string parameters, use the ? symbol just after the name of the page and if you want to add more than one parameter, use the & symbol to separate them

In the consuming page:

 protected void Page_Load(object sender, EventArgs e) { var adi = this.Request.QueryString["adi"]; var soyadi = this.Request.QueryString["soyadi"]; }

in ALL browsers, the browser will make padding and margin between all the things. to remove that and control the page yourself add this add the first line of your css:

* {margin:0 auto; padding:0}

auto makes all the things (except text and images) at the center of your page.

and for your table if you want texts to be on top of your td, add this:

.tlt{vartical-align:top; text-align:left;}

Sounds like you're still using the distribution code signing identity.

Assuming you're using Xcode 4.2, you can refer to the bellow image for how to change this:

[edit: better image] enter image description here

You also need to change your application identifier to match your code signing identity:

enter image description here

So, look at the string next to the selection you choose in the step 4 of the first screenshot (probably something in the format of com.yourcompany.appname) and make sure to use that same identifier in step 4 of the second screenshot.

This is no doubt a million dollar question, and I think the right solution depends always on the case.

Here goes my thoughts. Hope could help:

One simple trick (which, in fact, I read that it is surprisingly more efficient than joining strings with "+") is to use arrays of strings for each row and join them.

It continues being a mess but, at least for me, a bit clearer (specially when using, as I do, "\n" as separator instead of spaces, to make resulting strings more readable when printed out for debugging).

Example:

var sql = [ "select foo.bar", "from baz", "join foo on (", " foo.bazId = baz.id", ")", // I always leave the last comma to avoid errors on possible query grow. ].join("\n"); // or .join(" ") if you prefer.

As a hint, I use that syntax in my own SQL "building" library. It may not work in too complex queries but, if you have cases in which provided parameters could vary, it is very helpful to avoid (also subotptimal) "coalesce" messes by fully removing unneeded query parts. It is also on GitHub, (and it isn't too complex code), so you can extend it if you feel it useful.

If you prefer separate files:

About having single or multiple files, having multiple files is less efficient from the point of view of reading efficiency (more file open/close overhead and harder OS level caching). But, if you load all of them single time at startup, it is not in fact a hardly noticeable difference.

So, the only drawback (for me) is that it is too hard to have a "global glance" of your query collection. Even, if you have very huge amount of queries, I think it is better to mix both approaches. That is: group related queries in the same file so you have single file per each module, submodel or whatever criteria you chosen.

Of course: Single file would result in relatively "huge" file, also difficult to handle "at first". But I (hardly) use vim's marker based folding (foldmethod=marker) which is very helpfull to handle that files.

Of course: if you don't (yet) use vim (truly??), you wouldn't have that option, but sure there is another alternative in your editor. If not, you always can use syntax folding and something like "function (my_tag) {" as markers.

For example:

---(Query 1)---------------------/*{{{*/ select foo from bar; ---------------------------------/*}}}*/ ---(Query 2)---------------------/*{{{*/ select foo.baz from foo join bar using (foobar) ---------------------------------/*}}}*/

...when folded, I see it as:

+-- 3 línies: ---(Query 1)------------------------------------------------ +-- 5 línies: ---(Query 2)------------------------------------------------

Which, using properly selected labels, is much more handy to manage and, from the parsing point of view, is not difficult to parse the whole file splitting queries by that separation rows and using labels as keys to index the queries.

Dirty example:

#!/usr/bin/env node "use strict"; var Fs = require("fs"); var src = Fs.readFileSync("./test.sql"); var queries = {}; var label = false; String(src).split("\n").map(function(row){ var m = row.match(/^-+\((.*?)\)-+[/*{]*$/); if (m) return queries[label = m[1].replace(" ", "_").toLowerCase()] = ""; if(row.match(/^-+[/*}]*$/)) return label = false; if (label) queries[label] += row+"\n"; }); console.log(queries); // { query_1: 'select foo from bar;\n', // query_2: 'select foo.baz \nfrom foo\njoin bar using (foobar)\n' } console.log(queries["query_1"]); // select foo from bar; console.log(queries["query_2"]); // select foo.baz // from foo // join bar using (foobar)

Finally (idea), if you do as much effort, wouldn't be a bad idea to add some boolean mark together with each query label telling if that query is intended to be used frequently or only occasionally. Then you can use that information to prepare those statements at application startup or only when they are going to be used more than single time.

Try this :

mklink /D .\ venv\lib\python2.7\site-packages\httplib2

Note : mklink [OPTION] LINK TARGET (link and target are flipped compared to linux's ln -s)

Mklink Command Syntax :

MKLINK has 3 options /D, /H and /J. You also need to specify the path to the new symbolic link and the path to the original file or directory.

/D – used to create symbolic links for directories (d for directory)

/H – used to create hard links (h for hard link)

/J – used to create directory junction (j for junction)

By the way, always prefer mklink /D over mklink /J. Windows explorer will delete the entire contents of a junction (the latter) whereas when deleting a directory link (the former) it will just remove the link.

The dot . is the current directory (from where you are running the command). In the example above, I changed it to .\ to make it explicit.

For files : Helpful link.

If you can't get privilege with /D, use a hard link (option /H) :

mklink /H .\six.py venv\lib\python2.7\site-packages\six.py

Not a complete answer but I guess I am pointing in the right direction. You can get all the information about the user's browser and platform in javascript using the code below

 alert(navigator.userAgent);

You will have to create a list of known browsers and platforms, and you will have to compare the userAgent string with them to identify the respective browser/platform.

map[i][j] needs to be set to a new object, like map[i][j] = new Node('a') (well, if you had a constructor in Node which worked like that: it would be written Node(char a) { this.content = a; }).

You cannot do map[i][j].setContent('a') because it is not a preexisting Node object.

30910666 0 How can I querying a key value without retriving all data in Firebase?

I'm learning angularjs, firebase, angularfire by building a sample app. It's a dictionary app that any one can add a word, add several explanation to the word, add several common usage to the word, add example centences to the word. People can freely add new word via this web app. OR people can freely realtime search a word and display the content of that word. When I build the app.

I found everytime when I search a word, I have to load all the data and then check if the query string exist in the data and then display the content if exist. So, it's quite heavy if the library become very big.

How can I query a string if it exist from the server side and if exist, just download that piece of data?

Then on the block sections, add it to the "main content section" and configute the block.
Under Show block on specific pages, write the pages you want it to appear.

To print a block programatically

$block = module_invoke('webform', 'block_view', 'client-block-1'); //add your block id print render($block['content']);

8232448 0 Glassfish/Hibernate save without calling save explicitely

I am using Glassfish 2 and container managed persistence with Hibernate 3.2 as persistence provider. I have some finder method in my business logic, which manipulates some persistent entities, which have been fetched via the EntityManager. The manipulation is just changing a String property (deleting an element from a collection leads to the same effect).
I do not call anything like save or persist on my EntityManager. I just want to return some changed entities to my client.

It seems when the container commits the transaction the changes to my entity are saved automatically. Is there some magic Hibernate or Glassfish behaviour I missed completely so far?

Julia has its own interface to matplotlib called PyPlot. (you didn't really expect you'd simply type @pyimport and then just write python code into julia and magically have it all work, did you? :D )

See here for examples on how to use PyPlot; The hist plot in particular needs some special syntax to differentiate it from the julia native hist function (check the code for its example).

Here is your code translated to PyPlot to the best of my ability (works in Julia v0.6.0)

import PyPlot a = vec( rand( 1:1000, 400, 300 )) b = vec( rand( 200:700, 400, 300 )) c = vec( rand( 300:1200, 400, 300 )) common_params = Dict( :bins => 20, :range => (-100, 1300), :normed => true ) PyPlot.subplots_adjust( hspace=.4 ) PyPlot.subplot( 311 ) PyPlot.title( "Default" ) PyPlot.plt[:hist]( a; common_params... ) PyPlot.plt[:hist]( b; common_params... ) PyPlot.plt[:hist]( c; common_params... ) PyPlot.subplot( 312 ) PyPlot.title( "Skinny shift - 3 at a time" ) PyPlot.plt[:hist]( (a, b, c); common_params... ) PyPlot.subplot( 313 ) common_params[:histtype] = "step" PyPlot.title( "With steps" ) PyPlot.plt[:hist]( a; common_params... ) PyPlot.plt[:hist]( b; common_params... ) PyPlot.plt[:hist]( c; common_params... ) PyPlot.savefig( "3hist.png" ) PyPlot.show() # PS, this is unnecessary in PyPlot. All commands show instantly

I'm not sure why you chose a range of (-5,5); this was causing a problem on the third subplot. I've changed it to something more reasonable here just to show you this works.

You have to write your dates in YYYYmmdd format so that alphabetical order matches chronological order.
But you want your dates to be displayed in a better-looking format (legit).

The solution is to have 2 columns: one with the good-looking date, one with the YYYYmmdd date. This one will be hidden, but will be used by dataTable sorting function.

<table id="sorting"> <thead> <tr> <th>CPA</th> <th>Shipping</th> <th>Shipping (sorting format)</th> </tr> </thead> <tbody> <tr> <td>123</td> <td>Aug 28</td> <td>20150828</td> </tr> <tr> <td>327</td> <td>July 30</td> <td>20150730</td> </tr> <tr> <td>789</td> <td>Process</td> <td>0</td> </tr> </tbody> </table>

Then, the Javascript :

$('#sorting').dataTable( { "aoColumns": [ {"bSortable": true}, // First column: normal {"iDataSort": 2}, // Second column's sorting depends on third column (dataTable starts counting from 0, that's why third column is number 2) {"bVisible": false}, // Third column: hide it ] });

You'll find more tips and examples in DataTables' documentation.

If you don't use any transaction annotations the default will be transactions being required. Thus your DAO will run in a transaction and the persistence context will no later be flushed than when the transaction is committed.

From the JavaDoc on TransactionAttribute:

If the TransactionAttribute annotation is not specified, and the bean uses container managed transaction demarcation, the semantics of the REQUIRED transaction attribute are assumed.

From the JavaDoc on FlushModeType:

When queries are executed within a transaction, if FlushModeType.AUTO is set on the Query or TypedQuery object, or if the flush mode setting for the persistence context is AUTO (the default) and a flush mode setting has not been specified for the Query or TypedQuery object, the persistence provider is responsible for ensuring that all updates to the state of all entities in the persistence context which could potentially affect the result of the query are visible to the processing of the query.

This means that the persistence context might be flushed earlier, if you use a query whose result might be influenced by that flush.

30322329 0 mobile vs dektop authentication with client certificate HTTPS

Is there a different between mobile-authentication and desktop-authentication via certificate and https? And when, how to solve mobile authentiction with certificate?

We try to accomplish a connection to a site eg. https: example.com and authenticate the user via certificate. Before setup a CA and generate necessary certificates.

C# code from login site:

 var x509 = new X509Certificate2(this.Request.ClientCertificate.Certificate); var chain = new X509Chain(true); chain.ChainPolicy.RevocationMode = X509RevocationMode.Offline; chain.Build(x509);

that works great with IE desktop browser, and we can log every certificate information.
edit: It´s not working with firefox and there is no question about to choose a local certificate - same behavior as mobile.

Try the same url via mobile eg: iPhone or Windowsphone - nothing can read from the certificate.

Solution: as @Sean Baker said, install your CA cert as well on mobile. Thats the reason for me to upvote his answer as the right answer for this question.

Have a look at the webservers certificate. in my case, i have created the certificates on microsoft server and used a copy from "webserver" template, so that it was possible for me to export the certificate with a private key, cause that made it easier to deploy.

here is a url that point me in the right direction: https://support.microsoft.com/en-us/kb/931351

The login with firefox is working as well - you have to install your personal certificate within the fF administration. After that, you will be prompted to choose that certificate when opening the url via https.

document.write("b is : " + b + "<br />");

you trying to get the value of b variable but ur not calling the function print..

look at this :

var a = 45; var b; var c; function print(){ b = 10; document.write(a); } if(a == 45) { var c = 10; } document.write("a is : " + a + "<br />"); document.write("b is : " + b + "<br />"); document.write("c is : " + c + "<br />"); //-->

it will print the following:

 a is : 45 b is : undefined c is : 10

because b didn`t change as the function has not yet been called .. but c has changed by the if statement which lies on the global scope.

var a = 45; var c; function print() { b = 10; document.write(a); } print() if (a == 45) { var c = 10; } document.write("a is : " + a + "<br />"); document.write("b is : " + b + "<br />"); document.write("c is : " + c + "<br />"); //-->

That would only work if operator||(string,string) returned.. a sort of collection of strings and you had an Equals overload that took a string and that collection of strings and verified that the string is in the collection. Seems like a lot of work done behind the scenes for a very rarely used construct.

Especially since you already can do something like:

if(new string[]{"firstName","lastName"}.Contains(stringName)) // code

I solved it! This is the query:

select case when (select min(time(myColumn)) from myTable where time(current_timestamp, 'localtime') < time(myColumn)) is null then (select min(time(myColumn)) from myTable where time(current_timestamp, 'localtime') > time(myColumn)) else (select min(time(myColumn)) from myTable where time(current_timestamp, 'localtime') < time(myColumn)) end

Thx Tim & Dave who showed me the way.

4737686 0 How to generate SQL CLR stored procedure installation script w/o Visual Studio

I am working on CLR stored procedure using VS2010. I need to generate standalone deployment script to install this procedure at customer servers. Now I am using Visual Studio which generate such script when I press F5 and try to debug SP on DB server. This script is placed at bin\Debug\MyStoredProcedure.sql file. It looks like this:

USE [$(DatabaseName)] GO IF EXISTS (SELECT * FROM tempdb..sysobjects WHERE id=OBJECT_ID('tempdb..#tmpErrors')) DROP TABLE #tmpErrors GO CREATE TABLE #tmpErrors (Error int) GO SET XACT_ABORT ON GO SET TRANSACTION ISOLATION LEVEL READ COMMITTED GO BEGIN TRANSACTION GO PRINT N'Dropping [dbo].[spMyStoredProcedure]...'; GO DROP PROCEDURE [dbo].[spMyStoredProcedure]; GO IF @@ERROR <> 0 AND @@TRANCOUNT > 0 BEGIN ROLLBACK; END IF @@TRANCOUNT = 0 BEGIN INSERT INTO #tmpErrors (Error) VALUES (1); BEGIN TRANSACTION; END GO PRINT N'Dropping [MyStoredProcedure]...'; GO DROP ASSEMBLY [MyStoredProcedure]; GO IF @@ERROR <> 0 AND @@TRANCOUNT > 0 BEGIN ROLLBACK; END IF @@TRANCOUNT = 0 BEGIN INSERT INTO #tmpErrors (Error) VALUES (1); BEGIN TRANSACTION; END GO PRINT N'Creating [MyStoredProcedure]...'; GO CREATE ASSEMBLY [MyStoredProcedure] AUTHORIZATION [dbo] -- here should be long hex string with assembly binary FROM 0x4D5A90000300000004000000FFFCD21546869732070726F6772616D...000000000000000000 WITH PERMISSION_SET = SAFE; GO IF @@ERROR <> 0 AND @@TRANCOUNT > 0 BEGIN ROLLBACK; END IF @@TRANCOUNT = 0 BEGIN INSERT INTO #tmpErrors (Error) VALUES (1); BEGIN TRANSACTION; END GO PRINT N'Creating [dbo].[spMyStoredProcedure]...'; GO CREATE PROCEDURE [dbo].[spMyStoredProcedure] @reference UNIQUEIDENTIFIER, @results INT OUTPUT, @errormessage NVARCHAR (4000) OUTPUT AS EXTERNAL NAME [MyStoredProcedure].[MyCompany.MyProduct.MyStoredProcedureClass].[MyStoredProcedureMethod] GO IF @@ERROR <> 0 AND @@TRANCOUNT > 0 BEGIN ROLLBACK; END IF @@TRANCOUNT = 0 BEGIN INSERT INTO #tmpErrors (Error) VALUES (1); BEGIN TRANSACTION; END GO IF EXISTS (SELECT * FROM #tmpErrors) ROLLBACK TRANSACTION GO IF @@TRANCOUNT>0 BEGIN PRINT N'The transacted portion of the database update succeeded.' COMMIT TRANSACTION END ELSE PRINT N'The transacted portion of the database update failed.' GO DROP TABLE #tmpErrors GO

I am wondering, is it possible to generate such script without Visual Studio? For example, what if I build solution with MSBuild and then generate this script with some tool? I believe, that if I read assembly as byte array and then serialize it to hex string and insert into script template - it could work, but maybe there is some easier standard solution?

Thanks.

35815395 0 Child category is set current-cat on parent page

I have parent categories which have childs. I'm listing child categories on parent category page.

I'm using archive.php template.

Now I'm facing issue with current-cat class on parent category page. Seems that my first child category is getting current-cat class when on parent category page. This current-cat class should be on only when on current category page.

For example my parent category is Fruits. And when I'm on Fruits (category/fruits) page I can see child categories Apple, Orange, Banana. Problem is that Apple is getting current-cat class on Fruits page.

It should get that class only when on Apple page (category/fruits/apple).

Here is my current code:

global $wp_query; $ID = $wp_query->posts[0]->ID; $postcat = get_the_category($ID); $cat = $postcat[0]->cat_ID; $thiscat = get_category ($cat); $parent = $thiscat->category_parent; if ($parent == 0) { } else { $subcategories = get_categories('child_of='.$parent); $items=''; foreach($subcategories as $subcat) { if($thiscat->term_id == $subcat->term_id) $current = ' current-cat'; else $current = ''; $items .= ' <li class="cat-item cat-item-'.$subcat->term_id.$current.'"> <a href="'.get_category_link( $subcat->term_id ).'" title="'.$subcat->description.'">'.$subcat->name.' </a> </li>'; } echo "<ul>$items</ul>"; } ?>

dynamic_cast is known to break across module boundaries with many compilers (including MSVC and gcc). I don't know exactly why that is, but googling for it yields many hits. I'd recommend trying to get rid of the dynamic_cast in the first place instead of trying to find out why it returns null in your second scenario.

I'm not sure to what limitations the author of the python tutorial was referring, but I would guess it has in part to do with the way that method / attribute lookup is implemented in python (the "method resolution order" or MRO). Python uses the C3 superclass linearization mechanism; this is to deal with what is termed to be "The Diamond Problem".

Once you've introduced multiple inheritance into your class hierarchy, any given class doesn't have a single potential class that it inherits from, it only has "the next class in the MRO", even for classes that expect that they inherit from some class in particular.

For example, if class A(object), class B(A), class C(A), and class D(B, C), then the MRO for class D is D->B->C->A. Class B might have been written, probably was, thinking that it descends from A, and when it calls super() on itself, it will get a method on A. But this is no longer true; when B calls super(), it will get a method on C instead, if it exists.

If you change method signatures in overridden methods this can be a problem. Class B, expecting the signature of a method from class A when it calls super, instead gets a method from C, which might not have that signature (and might or might not not implement the desired behavior, from class B's point of view).

class A(object): def __init__(self, foo): print "A!" class B(A): def __init__(self, foo, bar): print "B!" super(B, self).__init__(foo) class C(A): def __init__(self, foo, baaz): print "C!" super(C, self).__init__(foo) class D(B, C): def __init__(self, foo, bar): print "D!" super(D, self).__init__(foo, bar) print D.mro() D("foo", "bar")

In this code sample, classes B and C have reasonably extended A, and changed their __init__ signatures, but call their expected superclass signature correctly. But when you make D like that, the effective "superclass" of B becomes C instead of A. When it calls super, things blow up:

[<class '__main__.D'>, <class '__main__.B'>, <class '__main__.C'>, <class '__main__.A'>, <type 'object'>] D! B! Traceback (most recent call last): File "/tmp/multi_inherit.py", line 22, in <module> D("foo", "bar") File "/tmp/multi_inherit.py", line 19, in __init__ super(D, self).__init__(foo, bar) File "/tmp/multi_inherit.py", line 9, in __init__ super(B, self).__init__(foo) TypeError: __init__() takes exactly 3 arguments (2 given)

This same sort of thing could happen for other methods as well (if they call super()), and the "diamond" doesn't have to only appear at the root of the class hierarchy.

The > means that the option:selected must be a child, or direct descendant of #OrganiastionSettingsAll. The example without the > means that option:selected can be a descendant at any level of #OrganiastionSettingsAll.

The child combinator (E > F) can be thought of as a more specific form of the descendant combinator (E F) in that it selects only first-level descendants.

I have a .NET Application that runs on a server with 16 COM ports, about 11 of which are currently connected to various devices, some RS485, many RS-232. (Diagram here: http://blog.abodit.com/2010/03/home-automation-block-diagram/). Most of these devices are running just 9600 baud, and most don't have very tight timing requirements. I have a thread per device handling receiving and while it runs at normal thread priority, all other non-communication threads run at a lower priority (as you should do for most background tasks anyway). I have had no issues with this setup. And, BTW it also plays music on three sound cards at the same time using high-priority threads from managed code and 1second DSound buffers, all without glitching.

So how tight are your latency requirements, what baud rate and how many serial ports are you trying to serve? The buffer on your UART at most normal baud rates is more than sufficient for garbage collection and much more to delay taking the next byte off it.

GC is not as evil as it is made out to be. On a properly prioritized threaded system with good management of object sizes and lifetimes and sufficient buffering (UARTS/Sound buffers etc.) it can perform very well. Microsoft is also continuously improving it and the .NET Framework 4 now provides background garbage collection. This feature replaces concurrent garbage collection in previous versions and provides better performance. See MSDN.

Because you just want to generate a php file I would suggest using string/regex replace in your ide/editor

going from

<option value="a">A</option>

<option value="a" <?= isset($array["a"]) ? "selected" : "" ?>>A</option>

In vim (but other editors should support this too) you can do this with

:%s/value=\(".*"\)/value=\1 <?= isset($array[\1]) ? "selected" : "" ?>/g

where the part you search for is

value=\(".*"\)

and this is the part you replace

value=\1 <?= isset($array[\1]) ? "selected" : "" ?>

using

\([someregex]\)

you can 'store' some variable and with \1 you can output it in the replace part 1

12476828 0 Sony Smartwatch widget refresh

I have a Problem with my Sony SmartWatch App. I've developed a widget with control, but after the App is installed by users on the device the scheduled refresh task of the widget starts automatically. This means the refresh task is running all the time, even if the user did not turn on SmartWatch Display or start the widget. This drains the battery. If I go to the widget screen and then turn the display from off, the scheduled Task stops like expected. But if I don't do this the task is running and running and running.... How can I detect if the Display is on and the widget is running?

Thank you very much!

P.S.: It makes no difference if the "Activate Widget" preference is checked or not....

EDIT: I've found out that the widget sourcecode does not fire if I uncheck the "Display as Widget" Checkbox in preferences. This means if the refresh schedule is running and I uncheck this box, the onDestroy is never called and so the cancel schedule also not....

8155196 0 Trying to integrate unit tests into Xcode for iOS 5.0 project, but cannot get files to link correctly

I am trying to add unit tests into my Xcode project for an iOS app that I am working on. I have SenTest working with basic examples, but the second I try to test any of the project code, I get linker errors like so:

"_OBJC_CLASS_$_Account", referenced from: objc-class-ref in Tests.o ld: symbol(s) not found for architecture i386

Obviously, I could solve this by duplicating my app target configuration into my test configuration, making all of the compile sources the same and such, but this will make two different targets that I will have to maintain, which is very unappealing. Also, I could refactor the project to use a static library and share between the app and the test targets, but that also is undesirable.

Is there any way that I can use the built objects from the app target in the test target? This sure seems like a lot of work to get unit testing in my project...

Thanks for any and all help!

I think your lucky with the '[c-a]' thing, My tr says tr: [c-a]: invalid destination string, which is what I would expect.

Character ranges, i.e. [a-z], in all the languages I've dealt with, need to ascend in value. Be happy that you've already figured out your solution.

Or write a function that you can use like tr "[a-z]" "[$( revCharRange a-z )]" (which would be more expensive due to the sub-shells required to create the reverse character range.

I hope this helps.

Create new page (http page) for your require functionality to show under new window. and point the newly created page url in click window code.

Or you can use native javascript to write you content in window. For example:

HTML

<button onclick="myFunction()">Try it</button>

Javascript

<script> function myFunction() { var myWindow = window.open("", "MsgWindow", "width=200, height=100"); myWindow.document.write("<p>This is 'MsgWindow'. I am 200px wide and 100px tall!</p>"); } </script>

You can notice from myfunction function doing couple of task, first it will generate new window object secondly we writing something under newly created window object and then fire it successfully.

By this method we do not need to worry about url to hit.

My fast approach to solving the problem is to create a function in an autoloaded helper file in the project i'm working on. This helper just redirects to the custom 404 page. So i just call show_my_404() instead of show_404()

function show_my_404(){ //Using 'location' not work well on some windows systems redirect('controller/page404', 'location'); }

(defclass locatable () ((zone :accessor zone :initform nil) (locator :initarg :locator :initform (error "Must supply a locator parameter for this class.") :allocation :class :accessor locator)))

The slot locator is shared in the class. It will be allocated somehow in the class object. The DEFCLASS form creates this class object. Thus the slot locator usually will be initialized when the class object is created and initialized. Way before the first instance of that class is created.

I have just implemented a solution like the one asked about here and it seems to work. I have an MVC application and have this code in my _Layout.chtml page but it could work in an asp.net app by placing it in the master page I would think. I am using local session storage via the amplify.js plugin. I use local session storage because as Mr Grieves says there could be a situation where a user is accessing the application in a way that does not cause a page refresh or redirect but still resets the session timeout on the server.

$(document).ready(function () { var sessionTimeout = '@(Session.Timeout)'; //from server at startup amplify.store.sessionStorage("sessionTimeout", sessionTimeout); amplify.store.sessionStorage("timeLeft", sessionTimeout); setInterval(checkSession, 60000); // run checkSession this every 1 minute function checkSession() { var timeLeft = amplify.store.sessionStorage("timeLeft"); timeLeft--; // decrement by 1 minute amplify.store.sessionStorage("timeLeft", timeLeft); if (timeLeft <= 10) { alert("You have " + timeLeft + " minutes before session timeout. "); } } });

Then in a page where users never cause a page refresh but still hit the server thereby causing a reset of their session I put this on a button click event:

$('#MyButton').click(function (e) { //Some Code that causes session reset but not page refresh here amplify.store.sessionStorage("sessionTimeout", 60); //default session timeout amplify.store.sessionStorage("timeLeft", 60); });

Using local session storage allows my _Layout.chtml code to see that the session has been reset here even though a page never got refreshed or redirected.

Fromt the docs:

When an 'r' or 'R' prefix is present, a character following a backslash is included in the string without change, and all backslashes are left in the string. For example, the string literal r"\n" consists of two characters: a backslash and a lowercase 'n'. String quotes can be escaped with a backslash, but the backslash remains in the string; for example, r"\"" is a valid string literal consisting of two characters: a backslash and a double quote; r"\" is not a valid string literal (even a raw string cannot end in an odd number of backslashes). Specifically, a raw string cannot end in a single backslash (since the backslash would escape the following quote character). Note also that a single backslash followed by a newline is interpreted as those two characters as part of the string, not as a line continuation.

Specifically, a raw string cannot end in a single backslash (since the backslash would escape the following quote character)

When you say "same method", there is really only one way to do that which is accessing the system clock. There is more than one method to do this, but they ultimately rely on the same thing. Also, the paper you referred us to relies on using Windows and Visual C and so this would not be applicable to Mac OS or Linux. As such, I'm going to try and give you platform independent methods for both MATLAB and C++. In either platform, this will give you the execution time as best as it can.

MATLAB

You can use the tic and toc commands. You start with the tic command, then do your processing, then you finish with t = toc. t will thus contain how much time has elapsed in between tic and toc.

Here is a quick example:

tic; for i = 1 : 100000 M = rand(100,100); %// Generate a 100 x 100 uniformly random matrix t = toc; fprintf('The amount of time that has elapsed is %f seconds\n', t);

If you want to compute FPS, simply measure how long it takes to execute the algorithm for one image/frame, then take the reciprocal. This time would be seconds/frame and so to compute FPS, take the reciprocal.

C++

You can use the ctime library, and use the time(NULL) call. This will return the time in seconds since Epoch (January 1, 1970). Like the MATLAB example, here is a C++ example:

#include <ctime> void func() { using namespace std; // Begin int start = time(NULL); // Put in processing code here // End - time in seconds int finish = time(NULL); // Measure time elapsed int time_elapsed = finish - start; }

To compute FPS, just follow what I did for the MATLAB example.

Another way using C++ (but with fair warning)

If you want microsecond precision to measure time in C++, you can use the clock() function. You can do something like this:

#include <ctime> void func() { using namespace std; // Begin clock_t start = clock(); // Put in processing code here // End - time in microseconds clock_t finish = clock(); // Measure time elapsed double time_elapsed = double(finish - start) / CLOCKS_PER_SEC; }

However, the clock() function will measure CPU time and not the actual time elapsed, so you will need to be careful here if you decide to do this. Check this posting out for more details: Easily measure elapsed time

30507086 0 User svg images in GWT ClientBundle (ImageBundle)

I normally use the GWT ClientBundle for managing my images within my application like this

@Source("icons/info.png") ImageResource info();

No I want to switch to .svg graphics but I didn't find a way to use svg in a ClientBundle like SVGResource or something. I know that svg is supported in GWT and there are possibilities to insert those graphics inside GWT, but I would like to use the advantages of the ClientBundle + the advantages of svg. Has anybody already solved this problem?

I found problem, in my app i made a custom side view controller implementation and I didn't queue animation actions for reveal a right and a left side view. That why i think spring board got crash (too many the same animations). I switched to similar open source controller with animation queue and now everything works.

Well, question is not fresh, but this situation may still become a piece of pain. You may use toJSON or toObject method to get normal, iterable object. Just like this:

media = media.toJSON() Object.keys(media.audio).forEach(...)

See this post for details about toJSON an toObject

25964910 0 Increase page size, hidden javascript slider appears and then doesn't work

I'm putting together a site that I want to be responsive to browser re-sizing. The site pulls one set of CSS styles for a page under 768px, another for any window larger than 768px.

I have a javascript slider (jcarousel) beneath my feature video at. If I open a window larger than 768px (using Chrome), then the javascript slider works fine. If I reduce the size of the window, the slider is hidden (with a display:none style) and other content is shown. And if I resize the window larger, the slider appears and works fine.

However, and here's my problem ... If I open a browser smaller than 768px, the CSS hides my javascript slider at the start, and shows my other content. But when I resize the window and make it larger (over 768px), the slider doesn't work right. I'm assuming the javascript and its associated styles need to be "activated" initially. Is there a way to get this working when a smaller window is opened first?

The URL you're passing in the example above is:

'DCC?command=' + encodeURIComponent(command)

The DCC part is actually part of the path to the webpage. It's short because it's a relative path. The fully qualified path would look something like www.sitename.com/DCC
The part after that (after the ? character) is called the query string. That's the part of the URL that contains data that you're passing to the server (in a GET transaction), and it follows this pattern:

a=somevalue&b=anothervalue&c=yetanother

So add "&varnameA=valueA" to that string to pass both command and varnameA:

xhr.open('GET', 'DCC?command=' + encodeURIComponent(command)+"&varnameA=valueA",true);

You can keep tacking on &varname=value strings until your query is around 2000 characters, because that's where browsers commonly start crapping out because the URL is too long.
Remember to encode any special characters in the values (that's what encodeURIComponent() is being used for) or you'll get some weird behavior. That means that you're appending something like +"&varnameA="+encodeURIComponent("valueA") for each additional variable/value pair you want to pass to the server.

"Why is the compiler not allowed to see"

I don't have an answer for safe bool, but I can do this bit. It's because a conversion sequence can include at most 1 user-defined conversion (13.3.3.1.2).

As for why that is - I think someone decided that it would be too hard to figure out implicit conversions if they could have arbitrarily many user-defined conversions. The difficulty it introduces is that you can't write a class with a conversion, that "behaves like built-in types". If you write a class which, used idiomatically, "spends" the one user-defined conversion, then users of that class don't have it to "spend".

Not that you could exactly match the conversion behaviour of built-in types anyway, since in general there's no way to specify the rank of your conversion to match the rank of the conversion of the type you're imitating.

Edit: A slight modification of your first version:

#define someCondition true struct safe_bool_thing { int b; }; typedef int safe_bool_thing::* bool_type; bool_type safe_bool( const bool b ) { return b ? &safe_bool_thing::b : 0; } class MyTestableClass { public: operator bool_type () const { return safe_bool( someCondition ); } private: bool operator==(const MyTestableClass &rhs); bool operator!=(const MyTestableClass &rhs); }; int main() { MyTestableClass a; MyTestableClass b; a == b; }

a == b will not compile, because function overload resolution ignores accessibility. Accessibility is only tested once the correct function is chosen. In this case the correct function is MyTestableClass::operator==(const MyTestableClass &), which is private.

Inside the class, a == b should compile but not link.

I'm not sure if == and != are all the operators you need to overload, though, is there anything else you can do with a pointer to data member? This could get bloated. It's no better really than Bart's answer, I just mention it because your first attempt was close to working.

This is my solution:

foreach ($arr1[0] as $key => $entry) { $arr1[0][$key][$arr1[0][$key]["Str1"]] = $arr2[0][$entry["Str1"]]; }

This produces the following output:

[ [ { "Str1":"ABC", "Str2":"Some Value", "Str3":"Something", "ABC":"Hello" }, { "Str1":"DEF", "Str2":"Another Value", "Str3":"Test", "DEF":"Test" }, { "Str1":"GHI", "Str2":"NULL", "Str3":"Blah", "GHI":"Something" } ] ]

14882787 0 How can I write a regex in Java that will perform a .replaceFirst on a group that is not in a comment?

So I need to return modified String where it replaces the first instance of a token with another token while skipping comments. Here's an example of what I'm talking about:

This whole quote is one big String -- I don't want to replace this @@ But I want to replace this @@!

Being a former .NET developer, I thought this was easy. I'd just do a negative lookbehind like this:

(?<!--.*)@@

But then I learned Java can't do this. So upon learning that the curly braces are okay, I tried this:

(?<!--.{0,9001})@@

That didn't throw an exception, but it did match the @@ in the comment.

When I test this regex with a Java regex tester, it works as expected. About the only thing I can think of is that I'm using Java 1.5. Is it possible that Java 1.5 has a bug in its regex engine? Assuming it does, how do I get Java 1.5 to do what I want it to do without breaking up my string and reassembling it?

EDIT I changed the # to the -- operator since it looks like the regex will be more complex with two chars instead of one. I originally did not reveal that I was modifying a query in order to avoid off topic discussion on "Well you shouldn't modify queries that way!" I have a very good reason for doing this. Please don't discuss query modification good practices. Thanks

8286477 0 Infix for All (leaves)

Infix[] works only at first level:

Infix[(c a^b)^d] (* -> (a^b c) ~Power~ d *)

As I want to (don't ask why) get the full expression switched to infix notation, I tried something like:

SetAttributes[toInfx, HoldAll]; toInfx[expr_] := Module[{prfx, infx}, prfx = Level[expr, {0, Infinity}]; infx = Infix /@ prfx /. {Infix[a_Symbol] -> a, Infix[a_?NumericQ] -> a}; Fold[ReplaceAll[#1, #2] &, expr, Reverse@Thread[Rule[prfx, infx]]] ] k = toInfx[(c a^b)^d] (* -> (c ~Times~ (a ~Power~ b)) ~Power~ d *)

But this has two evident problems, because

(c a^b)^d == a~Power~b~Times~c~Power~d
So what I get is not an efficient use of infix.
It is not robust, and fails for easy expressions such as k = toInfx[a/b + ArcTan[a/b]]

Is there an easy way to get Infix[] working for All (leaves)?

I just wrote this function :

Before that, I searched a lot in PHP for a similar string function. I'm still wondering if PHP has a similar function?

Presuming your website uses a "local" mail server, such as Postfix/Sendmail/Exim, you'd check the mail log. Generally (on Unix-ish systems), that's /var/log/maillog. It'll contain the full transcript of the email's passage through the mail server, from the moment it was handed off from PHP to when it goes out the door to the recipient.

However, some accepting servers will LIE to you about the mail - they'll accept it with the usual "200 OK" success code, then just dump it in the trash because it triggered a spam filter or your IP/IP-block has been blacklisted somewhere.

You could embed a web bug in the mail so that (hopefully) the client's email program will ping your server whenever they read the mail, but most mail clients now block remote images by default, so this is very unreliable as well.

Basically, email is a best-effort-not-guaranteed-to-succeed business, and the entire system is set up to lie to you about everything.

25888817 0 Android Bluetooth status 133 in onCharacteristicwrite

I'm new to Android and now doing a simple app that requires writing some data into a peripheral device.

Actually nothing goes wrong in a Samsung GT-S7272C device. But when I switch to Sony LT29i, there will always be a status 133 when I'm trying to write into a certain characteristic. I will give out some brief code.

BluetoothGattService syncService = gatt.getService(SYNC_DATA_SERVICE); BluetoothGattCharacteristic tChar = syncService.getCharacteristic(SYNC_TIME_INPUT_CHAR); if (tChar == null) throw new AssertionError("characteristic null when sync time!"); int diff = /*a int*/; tChar.setValue(diff, BluetoothGattCharacteristic.FORMAT_SINT32, 0); gatt.writeCharacteristic(tChar);

and the onCharacteristicWrite function:

@Override public void onCharacteristicWrite(BluetoothGatt gatt, BluetoothGattCharacteristic characteristic, int status) { Log.d(TAG, String.format("Sync: onCharWrite, status = %d", status)); try { if (status != BluetoothGatt.GATT_SUCCESS) throw new AssertionError("Error on char write"); super.onCharacteristicWrite(gatt, characteristic, status); if (characteristic.getUuid().equals(SYNC_TIME_INPUT_CHAR)) { BluetoothGattService syncService = gatt.getService(SYNC_DATA_SERVICE); BluetoothGattCharacteristic tChar = syncService.getCharacteristic(SYNC_HEIGHT_INPUT_CHAR); if (tChar == null) throw new AssertionError("characteristic null when sync time!"); tChar.setValue(/*another int*/, BluetoothGattCharacteristic.FORMAT_SINT32, 0); gatt.writeCharacteristic(tChar); } else if { ... } } catch (AssertionError e) { ... }

Writing into first characteristic has nothing wrong and control will reach the onCharacteristicWrite and enter the first if statement with status 0, which means success. Problem is the second writing action in the if statement, which will also trigger onCharacteristicWrite function but yield a status 133, which cannot be found in the official site. Then the device disconnect automatically.

I've confirmed that the data type and the offset are all correct. And because in another device it works really nice, I think there might be some tiny differences of the bluetooth stack implementation between different device that I should do something more tricky to solve this problem.

I've search for result for a long time. Some results lead me to the C source code(Sorry, I will post the link below because I don't have enough reputation to post more than 2 links), but I can only find that 133 means GATT_ERROR there, which is not more helpful than just a 133. I've also found a issue in google group, discussing some familiar questions, but I failed to find a solution here.

I'm a little bit sad because, if it is something wrong with the C code, even if I can locate what's wrong, I still have no way to make it right in my own code, right?

I hope that someone has the familiar experience before and may give me some suggestions. Thanks a lot!

vizier answered quite nicely but I am under the impression that his analysis has a mistake. I think he is not aware that Opencv has a version for android called OpenCV4Android. It is Java wrappers for the c++ functionality, meaning you can avoid using Android NDK and program everything in Java. This would make JavaCV "non-official" library redundant except for the fact that this one, besides wrapping opencv, also wraps a lot of other nice CV libraries.

Edit:

This doesn't change vizier conclusions about recommending OpenCV, it actually adds more points towards choosing it.

Both lines are showing a single input that connects to the inputs of two separate gates. For example, this line:

self.A.connect([self.A1.A, self.I2.A])

Is showing that the overall input A is wired to two inputs: input A on the AND gate A1 and input A on the NOT gate I2. That's indicated in the wiring diagram by the red circle/square:

Annotated wiring diagram

The line self.B.connect([self.I1.A, self.A2.A]) does the same thing with the B input to the XOR gate, wiring it to I1 and A2 (the blue circle above).

The error you saw with print is because it is a function in Python 3. For Python 2.x, you just do print "Stuff I want printed".

40079029 0 how to prompt a pop up message right after user input in jtextfield

I am new in Java and now trying to develop a simple program to support my research findings. In this program, I'll be displaying randomized images and users were to enter single integer in jtextfield provided. The users are required to count and answer the number of animals displayed. Since I want to develop the program as simple as possible, I imagine my tool will be straight forward.

Question 1: There will be a JTextField provided for user to input their answer. Is there any coding that could restrict user input right after a single integer(between 1-6) has been keyed in the box? As I need my program to be straight forward and easy to understand, I do not want user to click on any button so as to lead them to next image. May I know is there any way to restrict user input and lead the program to next image right after user enter a number without clicking any button? Question 1

Question 2: Right after the user key in the single integer answer, I would like to prompt a simple popup that includes a praise to user such as "Well done". Since the JOptionPane I'll be using will contain two buttons: "OK" and "cancel", may I know how to make sure the program leads to next randomized image after user click on "OK" button. Question 2

Question 3: Is there any ways to keep the input cursor for typing just in the JTextField provided? This is because I want the program as simple as possible that user do not need to waste their time moving their mouse and click at the jtextfield to start entering their answer. I want my program to work like: everytime user enter a single integer, a pop up message appear, user click "OK" and lead to next randomized image. At the next image, user just have to enter the answer without moving the cursor to click at the jtextfield(Example:By referring to image question 2, after user click "OK", how to make the program leads to next randomized image as image question 1). May I know is there any way to develop the program in such way?

This is my code.

The approach of this article is really something that can be become a pain, because you already have a generic repository and a generic IUnitOfWork in EF and creating the specific repository for each type just removes the benefit of the generic!

I am posting here a sample of how i have a generic Repository and my IUnitOfWork, with this you can have a very nice repository!

Recently (only a few months ago) the folks behind Phusion Passenger add support to Heroku. Definitely this is an alternative you should try and see if fits your needs.

Is blazing fast even with 1 dyno and the drop in response time is palpable. A simple Passenger Ruby Heroku Demo is hosted on github.

The main benefits that Passengers on Heroku claims are:

Static asset acceleration through Nginx - Don't let your Ruby app serve static assets, let Nginx do it for you and offload your app for the really important tasks. Nginx will do a much better job.
Multiple worker processes - Instead of running only one worker on a dyno, Phusion Passenger runs multiple worker on a single dyno, thus utilizing its resources to its fullest and giving you more bang for the buck. This approach is similar to Unicorn's. But unlike Unicorn, Phusion Passenger dynamically scales the number of worker processes based on current traffic, thus freeing up resources when they're not necessary.
Memory optimizations - Phusion Passenger uses less memory than Thin and Unicorn. It also supports copy-on-write virtual memory in combination with code preloading, thus making your app use even less memory when run on Ruby 2.0.
Request/response buffering - The included Nginx buffers requests and responses, thus protecting your app against slow clients (e.g. mobile devices on mobile networks) and improving performance.
Out-of-band garbage collection - Ruby's garbage collector is slow, but why bother your visitors with long response times? Fix this by running garbage collection outside of the normal request-response cycle! This concept, first introduced by Unicorn, has been improved upon: Phusion Passenger ensures that only one request at the same time is running out-of-band garbage collection, thus eliminating all the problems Unicorn's out-of-band garbage collection has.
JRuby support - Unicorn's a better choice than Thin, but it doesn't support JRuby. Phusion Passenger does.

Hope this helps.

I would say that the best alternative is to use Controllers since they, as you said, work well with FXML injection.

I don't see how letting one parent controller class control the widget is a bad thing since a class can implement interfaces of your choosing and even extend another class, inheriting its methods/attributes.

Plus, you can even use Scene Builder to easily manipulate the widget if you do import your fxml into scene builder.

18203319 0 Possible to add partial view into a pre-rendered partial view in MVC3/4 within browser request?

I am currently facing an issue about adding dynamic partial view into a partial view which is pre-rendered.

Situation: I have a view which contains a partial view (contains nothing initially, lets call it "A"). I want to add a dynamic partial view called "B" into the partial view "A" and keep stacking over time, and each of the partial view "B" would have their own GUID.

Possible to achieve this scenario?

Your code will return same values for fooIndex1 and fooIndex2 only if DateTime.Now.Millisecond is the same for different runs. It's specified in Random class specification. I've have run your code twice. First run gives fooIndex1 = 0, fooIndex2 = 2 and the second fooIndex1 = 1, fooIndex2 = 3.

Strange that you use r.Next(4). May be it's better to use r.Next(foosList.Count) to be able to access all items in your foosList.

You can achieve this by updaing your controller function as :

 vs.selectTag = function(term,k) { if(vs.toggleTags.item.indexOf(k) == -1){ vs.toggleTags.item.push(k) } else { vs.toggleTags.item.splice(vs.toggleTags.item.indexOf(k),1); } alert(term +' in tag #'+ vs.toggleTags.item); };

And update html to:

<li ng-repeat="(k, m) in tags" ng-class="{'selected':toggleTags.item.indexOf(k) > -1}" ng-click="selectTag(m.name,k)"> <div class="tag">{{m.name}}</div> </li>

The thread handling the request to the Index action with id=101 of your controller should be blocked. Threads handling other requests of other sessions will not be blocked. Even other requests for the same session may not be blocked depending on ReadOnly session attribute of corresponding controllers [SessionState(System.Web.SessionState.SessionStateBehavior.ReadOnly)].

25772669 0 understanding compareto() method in java

i came across a MIT lecture on recursion where they checked palindrome using recursion,and there they checked it using logic where they compare first and last alphabet and so on.. what i thought is something as follows

just a pseudo code:

 String original="abba"; String reverse = ""; for(int i=original.length()-1;i>=0;i--) { reverse+=new String(original.substring(i,i+1)); } if(original.equals(reverse)) System.out.println("palindrome"); else System.out.println("not palindrome");

i have two doubts

Is this logic better than recursion or conventional logic in terms of time complexity?
How does compareTo() method checks if strings are equal? DOes it compare bytecode or something?

Yes, absolutely, that's possible and pretty easy to do: all you need is to create an extension with a content script that will be injected into that particular page and remove the element for you.

To do what you want you'll need to:

Create a simple empty Chrome Extension (see here for the official guide) with a manifest.json file.
Specify the "content_scripts" field in the manifest.json, and declare the script you want to inject. Something like this:
```
"content_scripts": [ { "matches": "http://somesite.com/somepage.html", "js": "/content_script.js" } ] 
```
Take a look here to find out how content scripts work.
Create a content_script.js, which will delete the element for you. This script will basically contain the following two lines:
```
var element = document.querySelector('div.feedmain'); element.parentElement.removeChild(element); 
```

18541944 0 When making a POST call using a WebClient, how do I send duplicate values in the NameValueCollection?

I am unfortunately at the mercy of an API that forces the reuse of parameter names in a POST call.

The end result POST params look like this:

ArgNameA: xyz ArgNameB: abc ArgNameC: 123 ArgNameD: LMN ArgNameC: 789 ArgNameD: JKL ArgNameC: ... ArgNameD: ...

You get the idea.

I'm currently using a NamedValueCollection and sending that to a WebClient to do the POST call. That works fine but when I try to reuse ArgNameC and ArgNameD over and over, it appears to recognize the names as already existing in the collection and therefor won't add them (or maybe it updates them, I'm not sure).

How do I make a POST using a WebClient which allows me to reuse POST argument names?

No, not at the present time. C++0x will change the meaning of auto, and add a new keyword decltype that lets you do things like this. If you're using gcc/g++, you might also look into using its typeof operator, which is quite similar (has a subtle difference when dealing with references).

But, I also had unchecked Tools->Options->Debugging->"Enable Just My Code (Managed Only)". In fact, I didn't expect such exceptions to show up during degugging when I did so.

In addition to the exception above, I also saw

Suppose your dataObj contains a unique ID field, then any set data structure would be fine for your job. The immutable data structures are primarily used for functional style code or persistency. If you don't need these two, you can use HashSet<T> or SortedSet<T> in the .Net collection library.

Some stream specific optimization may be useful, e.g., keeping a fixed-size Queue<T>for the most recent data objects in the stream and store older objects in the more heavy weight set. I would suggest a benchmarking before switching to such hybrid data structure solutions.

Edit:

After reading your requirements more carefully, I found that what you want is a queue with user-accessible indexing or backward enumerator. Under this data structure, your feature extraction operations (e.g. average/sum, etc) cost O(n). If you want to do some of the operations in O(log n), you can use more advanced data structures, e.g. interval trees or skip lists. However, you will have to implement these data structures yourself as you need to store meta information in the tree nodes which are behind collection API.

"== false" is not very readable. Use ! instead.

If the "object value" is already of desired type (e.g. DateTime), it would be slower to convert it to string and then back again.

I would write instead

if (value is DateTime) return (DateTime)value;

I would not use var result = -999; as a return value.

If the conversion fails, you can either return Int32.MinValue (better than -999) or rather null.

Maybe also you would like to check for DBNull.Value? So first I would check for null and DBNull.Value, then "value is DateTime" check and the last thing would be DateTime.TryParse.

11810972 0 Always get "Error validating verification code." when requesting access_token

Well, I have done all my best to try to solve this problem, but, still, it's too annoying.

I decided to use OAuth with server-side authentication. So, I have followed Facebook documentation, and I have done the following step.

Create a link which redirect people to log in Facebook by https://www.facebook.com/dialog/oauth?client_id={APP_ID}&redirect_uri=http://abc.com/nextStep.php
In nextStep.php, redirect people to https://graph.facebook.com/oauth/access_token?code={CODE GENERATED BY FACEBOOK}&client_id={APP_ID}&redirect_uri=http://abc.com/thirdStep.php&client_secret={APP_SECRET}

The problem exists when proceeding to step 2. The page shows that:

{ "error": { "message": "Error validating verification code.", "type": "OAuthException", "code": 100 } }

I have googled for lots of time. Some people suggests to add a trailing slash in the redirect_uri, but it doesn't work. What should I do? And how can I get the user information after getting the access_token? Thanks for your help.

31382393 0 Meteor: How to treat elements that disappear and reappear

I have a page, that lists a collection, that can be filtered. As there are some fancy effects (hover dimming) on these items, they have to be applied once the page has loaded.

This works fine, but when I select a criteria that hides an item, and then make it reappear by deleting that filter, these effects are no longer applied to these items.

I have tried to create a template.rendered function, but that only works on the first page load.

I also thought that adding a 'hover #mydiv: function () {...}' inside the template.events section could help, but that still doesn't work.

I have even tried to listen to the changes made in the drop-down ('change #myselect': function () {...}) where the filters can be applied, but that's not working either.

I also tried to tie it to a dependency, that is submitted when the criteria is selected, that has also failed.

Any suggestions what else should I try?

Thanks, Alex

Edit 1:

This is how I treat the filters:

in Template.search.events:

'change #search-skills-select': function () { Session.set('searchFilter', $('#search-skills-select').val()); }

This then goes to:

/* This is of course properly handled for nulls, undefineds, etc. */ var searchFilterString = Session.get('searchFilter'); Profiles.find({profileAttributes: { $all: searchFilterString } });

The issue was resolved when the project was migrated onto another machine. Apparently the error had nothing to with incorrectness related to RMI. Although, the cause of the error and why it didn't resolve even after re-building the project is still unknown.

For this very reason it is recommend that you change your shebang line to be more path agnostic:

#!/usr/bin/env python

See this mailing list message for more information:

Consider the possiblities that in a different machine, python may be installed at /usr/bin/python or /bin/python in those cases, #!/usr/local/bin/python will fail. For those cases, we get to call the env executable with argument which will determine the arguments path by searching in the $PATH and use it correctly.

(env is almost always located in /usr/bin/ so one need not worry that env is not present at /usr/bin.)

I want to make the text size in the pickerView to become smaller if the text does not fit in the label. For example, whenever the text shows like this "This is a test for somebo..." I want it to automatically size itself to a smaller size so it should fit. Here is the code I'm using:

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view { UILabel *lView = (UILabel *)view; if (!tView) { tView = [[UILabel alloc] init]; [tView setFont:[UIFont systemFontOfSize:15]]; tView.numberOfLines = [categorie count]; } tView.text = [categorie objectAtIndex:row]; return tView; }

I tried to set the number of lines to 0 but that didn't solve my issue. I then tried to make the label sizeToFit, and that didn't work either.

I also tried making the label's frame height, taller, so it would be multiple lines, with didn't help either.

What did I get wrong?

I think teamnorge is on the right track His code won't work as posted, though, since the array isn't mutable.

Make your property a mutable array. Have the base class create it it init's init method:

In your base class header:

@property (nonatomic, retain) NSMutableArray *ignoreProperties;

Then in the init for your base class:

-(instanceType) init; { self = [super init]; if (!self) return nil; self.ignoreProperties = [@[@"property1"] mutableCopy]; }

And in the init for your subclass:

-(instanceType) init; { self = [super init]; if (!self) return nil; [self.ignoreProperties addObject: @"property2"]; //or to add multiple objects... NSArray *newProperties = @[@"property2", @"property3"]; [self.ignoreProperties addObjectsFromArray: newProperties]; }

For efficiency's sake, it might be better to make the array immutable and have the subclass's init method replace it with a an array created using arrayByAddingObject or arrayByAddingObjectsFromArray. (Immutable objects are less costly for the system than their mutable forms. In this case the array of properties will only be created once at initialization of your class, and then persist for it's lifetime.)

My first met of RadioButtons was too not easy. But basically, it's simple to use it.

private RadioGroup mRadioGroup; private View radioButton; int radioButtonID; int idx; //index of radio item in the list public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mRadioGroup= (RadioGroup) findViewById(R.id.mRadioGroup); .... }

Put this part of code to any click event method, idx always will return an index of checked radio button:

radioButtonID = mRadioGroup.getCheckedRadioButtonId(); radioButton = mRadioGroup.findViewById(radioButtonID); idx = mRadioGroup.indexOfChild(radioButton);

Where you have:

<Directory /home/bitnami/public_html/http/flasktest1> WSGIProcessGroup flaskapp WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory>

it should be:

<Directory /home/bitnami/public_html/http> WSGIProcessGroup flaskapp WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory>

as you are neither running your app in daemon mode or in the main interpreter because of the directives being in the wrong context.

That Directory directive then conflicts with one for same directory above so merge them.

If using mod_wsgi 3.0 or later count instead perhaps drop that second Directory block and use:

WSGIDaemonProcess flaskapp threads=5 WSGIScriptAlias /flasktest1 /home/bitnami/public_html/wsgi/flasktest1.wsgi process-group=flaskapp application-group=%{GLOBAL}

Note that processes=1 has been dropped as that is the default and setting it implies other things you likely don't want. You also don't need to set user/group as it will automatically run as the Apache user anyway.

Question:

I would like to know what fd should mean? (it seems to be stdin, yet I do not understand why)?

Background

My comprehension is that terminal is input and output together, as my understanding was that a /dev/tty or /dev/pty yields stdin, stdout and stderr together.

First of all don't add the validator (or anything else for that matter) into vendor namespaces. Instead put it somewhere within your application code. Don't know how your app is structured, but lets say ./module/YourModule/src/YourModule/Validator/ZendValidatePesel.

Then reference your validator class with a full, qualified name, so following my guess it'd be something like:

'validators' => array( array( 'name' => 'YourModule\Validator\ZendValidatePesel', 'options' => array( // ... ), ),

As far as I know that will directly instantiate the validator for you. Not-so-fun-fact: even if you'd register your validator there under the same name as the fqcn, it won't go through the ValidatorPluginManager -- something that I hope will be, or already is fixed in the framework (if it is somebody let me know, because it'd love to have validators with dependencies at last).

Well, first of all, you can never return an array. You have two options, the more commonly used option is to create the array in main, and pass a pointer to it as one of your arguments (generally "output" arguments are the last one, but this obviously doesn't matter), or your other option, is to create the array in your function (it has to be static otherwise it will go out of scope once the function returns), and return a pointer to the array. Considering that this 'static' method isn't recommended, your second option could instead be malloc()ing space for the array in your function, and returning the pointer to that (don't forget to free() in main!).

The video that @OleksandrKravchuk links to returns a pointer to a local variable, this is a bad idea (you can use the static trickery, but this is not a perfect solution either. 99% of time having it in as an argument is the way to do this). To be clear, there is NO WAY to return an array (by value, anyways). Don't let his answer confuse you.

A lot of misconception here.

your variable blob is not a Blob, but a string, the url of .file-preview-image.
FileReader can't do anything from this string. (Or at least not what you want).
in the onload callback of the FileReader, you are just checking if the result is equal to an undefined variable dataURI. That won't do anything.
you are trying to console.log the call to readAsDataURL which will be undefined since this method is asynchronous (you have to call console.log in the callback).

But since I guess that what you have is an object url (blob://), then your solution is either to get the real Blob object and pass it to a FileReader, or to draw this image on a canvas, and then call its toDataURL method to get a base64 encoded version.

If you can get the blob :

var dataURI; var reader = new FileReader(); reader.onload = function(){ // here you'll call what to do with the base64 string result dataURI = this.result; console.log(dataURI); }; reader.readAsDataURL(blob);

otherwise :

var dataURI; var img = document.querySelector(".file-preview-image"); var canvas = document.createElement('canvas'); canvas.width = img.width; canvas.height = img.height; canvas.getContext('2d').drawImage(img, 0,0); dataURI = canvas.toDataURL();

But note that for the later, you'll have to wait that your image actually has loaded before being able to draw it on the canvas.
Also, by default, it will convert your image to a png version. You can also pass image/jpegas the first parameter of toDataURL('image/jpeg') if the original image is in JPEG format.
If the image is an svg, then there would be an other solution using the <object> element, but except if you really need it, I'll leave it for an other answer.

You need to increment your compteur variable (I'm assuming that you have it for this purpose) and check it's value on every submission. Something like this:

var resultat = Math.floor(Math.random() * 100) + 1; var compteur = 1; $('div').html("( answer is : " + resultat + " )"); $('form').on('submit', function(e) { e.preventDefault(); if (compteur < 8) { var inputVal = $('#number').val(); var nbInput = Number(inputVal); compteur++; if (nbInput !== resultat) { if (nbInput < resultat) { $('h2').html(inputVal + ' is too small'); } else { $('h2').html(inputVal + ' is too big'); }; } else { $('h2').html('Yes! ' + inputVal + ' is the right number'); }; } else $('h2').html('You reached the limit of 7 guesses.'); });

You probably want to redirect your System.out to another place.
If you want to work with Swing then you can look here

Then it's the duty of the other place where you redirect it.
But right now it's only a thing of your IDE (Eclipse). It is independent from your Java logic.

If your think serious about it. You don't want to play your text adventure in your Eclipse IDE. So if you are using Windows the next question is if you want to use the Window command line. This may already be enough for you. But I still would recommend to make first thoughts about in which kind of window you want to have your text output

No, you can not calculate the furthest point for each point in O(n). The best you can obtain is O(n log n) with a 2-d tree. You can do this with a technique, similar to finding a closest point.

7995584 0 Can I 'match' values in 2 arrays and then use the subsequent 'matched' value?

I'm trying to achieve the following though with my intermediate JavaScript skills I'm not sure if this is possible.

This is related in part to this question.

Now I have 2 arrays

a) Has the various language in (e.g. "en-GB", "fr", "de" etc)
b) Has a suffix of a URL based on the browser language above (e.g. "fr/","de/","uk/")

What I am trying to achieve is:

1) User hits a page, browser detects which browser it is using from the array (a)
2) Depending on what the browser is based on (a), it then searches through (b) and if they match, e.g. if the language is "fr" it will use the suffix "fr/" from the array in (b).
3) It will then add this suffix to a top level domain (which is always constant)

Is this even possible to achieve (I'm sure it is)? Can it be done purely via JavaScript (or JQuery)? How would I go about doing this?

Here's some of the code I have so far:

var IAB_Array = new Array("de-at","nl-be","fr-be","da","de","hu","en-ie","ga","es","fr","it","nl","no","pl","en","en-GB","en-US","en-gb","en-us"); //language array var IAB_suffix = new Array("at/","be-nl/","be-fr","den/","de/","hu/","ie/","es/","fr/","it/","nl/","nor/","pl/","uk/"); //URL suffix Array var IAB_lang = "en-GB"; //default language var IAB_link = "http://www.mysitegoeshere/"; if(navigator.browserLanguage) IAB_lang = navigator.browserLanguage; //change lang if detection supported if(window.navigator.language) IAB_lang = window.navigator.language; //change lang if detection supported function IAB_Lang_detect () { //execute search for (var i=0;i<IAB_Array.length;i++) { if(IAB_Array[i]==IAB_lang) { document.write(IAB_Array[i]); //output matched array value } } return false; } var IAB_URL = "<a href="+IAB_link+IAB_suffix[1]+">"+IAB_link+IAB_suffix[1]+"</a>"; //this is the resulting URL document.write(IAB_URL); IAB_Lang_detect ();

I hope someone can help as I'm a little confused! It's more so the matching the values from the 2 arrays and then subsequently selecting the correct suffix that I'm having trouble with.

Thanks

text-stroke is actually avalaible in webkit , using vendor prefix. So is text-fill.

In near futur it could be avalaible in other browser too , check it out here : http://caniuse.com/text-stroke

To stroke text in CSS, you need to use multiple text-shadow to increase as much as needed the shadow to turn it into a full strike color .

public class scriptFlashingPressStart : MonoBehaviour { public GameObject off_Logo; public float dead_logo = 1.5f; void OffLogo() { off_Logo.SetActive(false); } //function onclick button //remove item after a certain time after pressing ??? void press_start() { InvokeRepeating("OffLogo", dead_logo , ...); } }

4741881 0 OpenGL: how to use buffer_objects to draw

In page 103 of OpenGL redbook, they give an example (example 2-17) about how to use buffer_object to draw something.

#define BUFFER_OFFSET(bytes) ((GLubyte*) NULL + (bytes)) GLuint buffers[NUM_BUFFERS]; GLfloat vertices[][3] = { { -1.0, -1.0, -1.0 }, { 1.0, -1.0, -1.0 }, { 1.0, 1.0, -1.0 }, { -1.0, 1.0, -1.0 }, { -1.0, -1.0, 1.0 }, { 1.0, -1.0, 1.0 }, { 1.0, 1.0, 1.0 }, { -1.0, 1.0, 1.0 } }; GLubyte indices[][4] = { { 0, 1, 2, 3 }, { 4, 7, 6, 5 }, { 0, 4, 5, 1 }, { 3, 2, 6, 7 }, { 0, 3, 7, 4 }, { 1, 5, 6, 2 } }; glGenBuffers(NUM_BUFFERS, buffers); //Generate NUM_BUFFERS of buffers and put them in buffers array. glBindBuffer(GL_ARRAY_BUFFER, buffers[VERTICES]); //bind buffers glBufferData(GL_ARRAY_BUFFER, sizeof(vertices), vertices, GL_STATIC_DRAW); //allocate space for buffers glVertexPointer(3, GL_FLOAT, 0, BUFFER_OFFSET(0));

Here, we suppose to have a point to a array to specify in which array we will find the data. Then is that should be a pointer to some memory address in server?

I just do not understand that BUFFER_OFFSET(0).

Does that mean that there is always only one Vertex_Array in server and the program will choose that address automatically? The BUFFER_OFFSET(0) just tell you where to start in this array?????????

glEnableClientState(GL_VERTEX_ARRAY); glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, buffers[INDICES]); glBufferData(GL_ELEMENT_ARRAY_BUFFER, sizeof(indices), indices, GL_STATIC_DRAW); glDrawElements(GL_QUADS, 24, GL_UNSIGNED_BYTE, BUFFER_OFFSET(0));

Same thing here. We suppose to give a address at the last parameter. But I do not see that BUFFER_OFFSET(0) is a useful address.

Yes - you can do that using Geneos commands. For you reference I have added a sample screenshot of how your command will look like in Geneos Gateway Editor. Notice that it is set to run on Netprobe and the checkbox Enable password is checked. This means when you run this command from inside the Geneos Active Console it will ask for a password. Since this command is set to run on Netprobe, you need to define the password on probe. This is under the Advanced Section of Probe. See the below screenshot:

on the first how did you run your App? I noticed that when i run an App in Debugmode, the Debugger eats 50% of the performance of my mobile Device. So if you just run your App the onFinish works much faster.

A second point is to detect the timeout manually in the onTick Method an block the taps after some time with a boolean

private boolean tapBlock = false; private void beginTimer() { new CountDownTimer(10100, 1000) { public void onTick(long millisUntilFinished) { if (!tapBlock) { time.setText("Time: "+millisUntilFinished/1000); if (millisUntilFinished<100) { tapBlock = true; } } } public void onFinish() { time.setText("Timeout!!!"); finalTap++; tapBlock = false; } }.start(); }

This is a bit around but its maybe faster and you have to add the "tapBlock" to the update method

35905803 0 Gradle: interchangeably use AAR or project dependency

I have an AAR library that I want to distribute to partners along with a sample project that uses it. I want to also use the same sample project for manual testing while developing the AAR library. Thus, I would like to be able to use the library project as a dependency when developing, and the AAR file as a dependency when distributing.

I tried to define two flavors in the sample application:

 productFlavors { aar {} project {} }

...and then define dependencies like this:

 dependencies { //other dependencies projectCompile project(':myLibrary') aarCompile 'com.example.mylibrary:myLibrary-release@aar' }

The aar flavor builds if I comment out the dependency for the project flavor, but if I leave both uncommented, Gradle sync fails if the myLibrary directory is not present - despite the fact that the project build flavor is not part of the current build variant.

What is the correct way to do this? Or do I have to choose between creating a whole separate project for distribution or always referencing the AAR even when debugging/testing?

20216486 0 Using import java.util.Random; nextInt and user input

I am fairly new to java so this will probably seem like a basic question. I am trying to use the random java.util and nextInt to create a random number in a range specified by user input and then cast it as a character, to then be stored in an array;

gridCells[x][y] = (char)(r.nextInt(numberOfRegions) + 'a');

However, because I want nextInt to use user Input, and although im controlling the range of values, im guessing the error is caused because nextInt thinks numberOfRegions could be 0?

// Map Class import java.util.Random; public class map { // number of grid regions private int numberOfRegions; private boolean correctRegions = false // grid constants private int xCord = 13; // 13 so the -1 makes 12 for a 12x12 grid private int yCord = 13; // initiate grid private int[][] gridCells = new int[xCord][yCord]; Random r = new Random(); map() { } // ask for number of regions public void regions() { keyboard qwerty = new keyboard(); // keyboard class while(correctRegions = false) { System.out.print("Please enter the number of regions: "); numberOfRegions = qwerty.readInt(); if(numberOfRegions < 2) // nothing less then 2 accepted { correctRegions = false; } else if(numberOfRegions > 4) // nothing greater then 4 accepted { correctRegions = false; } else { correctRegions = true; } } } // fills the grid with regions public void populateGrid() { for(int x =0; x<gridCells[x].length-1; x++) // -1 to avoid outofboundsexception error { for(int y =0; y<gridCells[y].length-1; y++) { gridCells[x][y] = (char)(r.nextInt(numberOfRegions) + 'a'); } } } public void showGrid() { for(int x=0;x<gridCells[x].length-1; x++) { for(int y=0; y<gridCells[x].length-1; y++) { System.out.print(gridCells[x][y] + " "); } System.out.println(); } } }

The bandwidth requirements are almost the same as the bandwidth requirement for opus and vp8. Real time audio typically has a bitrate of 40-200kbit/s. Video requires at least 200 kbit/s (500kbit/s if you want to see people's faces).

According to webrtc-experiment the minimum bandwidth for opus is 6kbit/s and for vp8 100kbits/s. So in total that makes 106kbit/s but when you account for the overhead of the webrtc protocol stack and constantly varying network conditions I would guess that 200kbit/s is the minimum if one wants stable video and audio.

Chrome and Firefox both use opus and vp8 so the bandwidth requirements should be the same. Although I don't have any hard data to prove it.

You can see the current traffic generated by webrtc by going to chrome://webrtc-internals and inspecting all the charts.

The answer is in apple SCNNode documentation. Try using flattenedClone() method instead of clone(). And one more thing, it's not needed any for statement. Here is a little example in Swift:

nodeB = nodeA.flattenedClone()

Now, nodeB contains all children nodes of nodeA

The behaviour of this operator is different across various versions of Ruby. You're probably using an older one, in which case this is to be expected.

Here's an excerpt from the docs for Ruby 1.8.7's String class

If passed a single Fixnum, returns the code of the character at that position.

This has been changed and the newer versions of Ruby (1.9.x and above, according to this site ) simply print the character as a String. See the docs for Ruby 2.1.0.

If passed a single index, returns a substring of one character at that index.

Ruby 1.9.3, which I happen to have installed on the machine I'm using displays exactly the same behavior:

"Mwada"[0] => "M" "Mwada"[0].class => String

The problem is that the EditField will still try to use all of the width, which causes the VerticalFieldManager to also use the entire width available to it, effectively shoving off the password field.

The only way I know of to do something like this would be to create classes that explicitly set their width to 50% of the screen. There are two ways of doing this: either create subclasses of EditField and PasswordEditField, or create a subclass of HorizontalFieldManager. The former option will be easier and more reliable across the different platforms, but will require two classes instead of one.

To do this, you'll want to create a subclass of EditField and override its layout method to look something like:

protected void layout(int maxWidth, int maxHeight) { super.layout(maxWidth, maxHeight); this.setExtent(Display.getWidth()/2, this.getHeight()); }

Similarly for the PasswordEditField.

Depending on how you want it to behave, you might have to override other methods as well. For instance, this code will (I'm pretty certain, haven't tested it specifically) cause any extra characters to be truncated if they dont fit in the desired area. If that's not what you want, you might have to override paint or change the layout based on the current text. Also, you should test it when tilting the storm screen to ensure the size updates correctly - it should work in most cases, but there is a bug that causes it to not update layouts/sizes if you have certain configurations of managers on the screen.

If you decide to go the manager route (which, again, I don't especially recommend, as you'll probably run into many more issues), you'll want to extend either Manager or HorizontalFieldManager (might be easier to do the former, so you don't have to deal with some of the quirks of the HFM), and override its sublayout method. In this method, you'll want to call layoutChild and setPositionChild (in that order) for every field in the manager (in your case, the user field and the password field). Then, at the end, you'll want to call setExtent. I would refer you to the blackberry docs on this matter, but in all honesty you're better off searching for how to implement blackberry custom managers, or asking questions on SO.

All that said, you might also want to reconsider why you want to do this. I can guarantee you from experience that there will be some phones where the UI does not look right - we tried a similar approach once, and eventually scrapped it because we couldn't get it to work from a UI standpoint on all devices. There are lots of different resolutions - some very narrow, some very wide - and if you go with this UI then some devices will have very cramped logins. IMHO, it would be preferable to be consistent with the other BlackBerry applications, and have username and password on different lines.

2648936 0 Issue with Facebook JS API, revokeAuthorization

I am trying to integrate FB connect into our user profile screen. Although, I'm having an issue with FB.ApiClient.revokeAuthorization.

http://pastie.org/921942

The basic problem is that I revoke the auth at line 44 after the user clicks the disconnect button.

After that, all subsequent API calls don't have a valid session to even check user status. I've tried wrapping blocks in a FB.Connect.forceSessionRefresh block, but then the code will never be called at all.

I'm not sure what the proper workflow should be for this purpose. Right now it's basically...

User arrives at profile NOT connected to the application.
User clicks on the connect button.
Once connected, DOM manipulation occurs to hide the connect button and add in a disconnect button.
User clicks on the disconnect button.
User's authorization to the application is revoked and (it seems) the API session to the FB server is invalidated.
DOM manipulation occurs to hide the disconnect button and readd the connect button.
User clicks on the connect button.
Once connected, the FB.Connect.get_loggedInUser() doesn't return the actual user.

I think this is a problem and I think if I set it to 1GB it will increase the performance and capability, is that right ?

It will mean the DB will need to stop less often to grow, certainly, and data inserts will occur more frequently. It will reduce the impact of data file growth. However, Microsoft says that autogrow is not intended to manage planned file growth. It's intended to handle unexpected growth. Autogrow is just not designed to work the way you're using it. The design intent is that you know how much data you will be storing and you have planned accordingly and already correctly sized your DB.

This might be somewhat unrealistic given your application, however. If your system is designed to hold all data ever collected indefinitely, your capacity planning is a bit difficult.

This is why it's common practice to differentiate operational data from warehoused data. Your operational data is stored in one database, which you can predict the growth for within a given time frame (usually 1 or more years). After a period of time, older data is archived to data warehouses, which may be very large or single year containers, but since data is inserted here rarely, you know what your capacity is going to be.

If I were you, I would pick a time frame to plan for. Say one month, quarter, or year. Every period of time, manually grow your database large enough so that the free space is what you expect to need to accommodate the coming period. Don't forget to include index space! Use the SSMS reports to help your estimates!

This means you can do your growth during off-hours or maintenance windows and your application is never waiting on the DB to finish growing. I would then set autogrowth to be about 5% of the free space you're planning for. If you underestimate, you'll get an idea by how much when you look at your shrink/grow logs. You can then increase for next month. Eventually, you'll learn what you need on a monthly basis. Just make sure to grow based on free space in the database and not absolute file size.

36445189 0 libcurl use same user defined port to send periodic request

I am working on a project need to send periodic alive message to https server.

Because of security issue, we need to use minimal number of ports (blocking unused ports as many as we can).

I am using c++ libcurl easy interface to send https request in linux.

I have tried to use the same curl handler object (CURL object) and set CURLOPT_LOCALPORT to a port number. The first request is ok. But in the second, libcurl verbose mode said address already in use. However, when I comment out the port set through CURLOPT_LOCALPORT, it works on second connection also, and by setting VERBOSE to 1, I can see "Re-using existing connection" print out, which is missing in version setting up local port. And I check with linux netstat, find out that it is using the same port. I cannot figure out why setting up local port will make it failed.

And also, I have tried to close the connection using curl_easy_cleanup, but due to tcp time_wait state, we cannot reuse the port in a while, that's not what I want.

Could anyone provide a solution or suggestion to us? Thanks a lot.

Edit My reason using one port is not to keep opening and closing connection too much.

7688070 0 Why is comparing the ".constructor" property of two windows unreliable?

I'm trying to understand why the following is not working as I would think it does. I'd like to check whether an object is a window. I was thinking that checking the constructors of the current window and another window would work.

So, first creating another window:

var popup = window.open('', '', '');

And then checking with:

popup.constructor === window.constructor;

But for some reason the results vary among browsers:

IE7: Returns true
- But that's simply because .constructor === undefined
IE8: Returns false
IE9: Throws an error with no text ("")
Chrome: Returns false
- Though in both cases .constructor === DOMWindow - but DOMWindow is not accessible directly like this
Opera: Returns false
- Though in both cases .constructor === Object
Firefox: Returns false
- Though in both cases .constructor === Window

Why isn't this reliable and working correctly? jQuery simply checks for "setInterval" in window, but I'd like to create a more robust function for checking whether an object is a window.

When a servlet runs, the user from an operating system perspective is the user that the Servlet Container (Jetty, Tomcat, Glassfish, etc) is running as. It is the rights of that user that are being checked by the operating system. The owner of the JSP file is irrelevant. Well, to be precise the JSP file has to be readable by the user that the Servlet Container is running as otherwise it can't be executed but in terms of OS permissions for the actions defined by that JSP, the only thing that matters is the user the Servlet Container is running as.

As it seems this is a common issue I'll try to provide more information here:

First, make sure you check whatever code you are using on your Analytics. The first answer provided here pasted a code using Google GA.JS code, but many websites today uses the new Analytics.JS code (my case). So my suggestion is to copy your GA code from your website or from your GA panel.

Second, check if your GA code is being passed on your Instant Article RSS feed correctly (i'm assuming you are using Wordpress with some plugin to build a RSS). If you are using the new analytics.js method the code inside your RSS feed (per article) should be like this:

<!-- Adding tracking if defined --> <figure class="op-tracker"> <iframe> <script> (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o), m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) })(window,document,'script','https://www.google-analytics.com/analytics.js','ga'); ga('create', 'YOUR_GA_ID', 'auto'); ga('send', 'pageview'); </script> </iframe> </figure>

Third, if your articles were already on Facebook Instant Article Production list BEFORE you added the Analytics code, they will NOT update / load the code. The best way to test is to edit any of your articles (a simples change of punctuation is enough) and republish it on your wordpress. Then go to your IA panel on Facebook, Configuration and click to reload / rebuild your RSS. Wait a little then check on the list of I.A that the post will update (you will see the date change), then open it on the edit option and check at the end of the code. Your GA code should be there.

So, if everything is good now, your last step (at least was for me) is to delete all the old Instant Articles on Facebook (I'm assuming you don't have them published yet) and reload the RSS feed on the Configuration area, so it will rebuild your articles with the GA code on them.

Hope this helps.

PS: I'm NOT using the plugin from Automattic to publish IA from WP as it's just garbage. There is one way simpler that work's w/o any trouble: https://wordpress.org/plugins/allfacebook-instant-articles/

A rewrite rule like this will prevent files existing on disk not to be rewritten:

RewriteCond %{REQUEST_FILENAME} !-f # Do not rewrite static files RewriteCond %{REQUEST_FILENAME} !-d # Do not rewrite static directories

As for your second question, please clarify, im not sure i understand what you mean.

You could switch your MVC action to ActionResult instead of FileStreamResult. Then just point to it with a regular link, no jquery post is needed:

<a href="/controller/GetFile"target="_blank">

7502566 1 FieldError on ManyToMany after upgrading to Django 1.3

Just been updating to Django 1.3 and come across an odd error. I'm getting the following error from some code which works with version 1.2.7.

FieldError: Cannot resolve keyword 'email_config_set' into field. Choices are: id, name, site, type

The odd thing being email_config_set is a related name for a ManyToMany field. I'm not sure why django is trying to resolve it into a field.

The error occurs deep inside django:

To dynamically create an attribute based on certain conditions, re-jig your code to this...

<xsl:element name="{if (@role='rowhead' ) then 'th' else 'td'}"> <xsl:if test="fn:exists(@def)"> <xsl:attribute name="class" select="concat('def-', @def)"/> </xsl:if> <xsl:apply-templates /> </xsl:element>

If you use xsl:attribute immediately after xsl:element the attribute gets appended on to the element. Note that attributes must be created before any child elements.

The response contains no content in the geodata-lat element. It appears that client side code is getting that data so your response only is looking at the html that the server generated. I tried this out myself and this is the section of the response you are looking for. You can see it is empty: xmlhttp response

If you try an element that has content (geodata-kml-button), it does pull in a value ("Download KML file"). Ignore the ByteArrayToString() call, that was just me testing: enter image description here

If they don't have a real API then I don't think you can get your data this way.

27304748 0 Significant performance differences in JTextPane when text contains linefeed

I wrote a method that writes hello world!\n 10000 times in a JTextPane. I recognized a significant performance drop when using hello world! without linefeed.

Example:

import java.awt.BorderLayout; import javax.swing.*; import javax.swing.text.*; public class JTextPaneTest { JTextPane textPane = new JTextPane(); Document doc = new DefaultStyledDocument(); //constructor JTextPaneTest() { for(int i=0;i<10000;i++) { try { doc.insertString(doc.getLength(), i+" hello world!", null); } catch (BadLocationException e) { // TODO Auto-generated catch block e.printStackTrace(); } } textPane.setDocument(doc); createWindow(); } public void createWindow() { JFrame frame = new JFrame(); frame = new JFrame("frame"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(400, 300); frame.setLocationRelativeTo(null); frame.getContentPane().add(new JScrollPane(textPane), BorderLayout.CENTER); frame.setVisible(true); } public static void main(String[] args) { System.out.println("start..."); float startTime = System.nanoTime(); new JTextPaneTest(); float stopTime = System.nanoTime() - startTime; System.out.println("elapsed time main: "+stopTime/1000000000+ "s"); } }

what could be the reason for that phenomena? Any ideas?

34944194 0 Show user his products

This is my first year with HTML, PHP, JAVASCRIPT and mysql!

And i am having a problem, im making a website that users can only see them products. For example: Admin created a product for MARTA, when MARTA log in she can see her product.

I have created the table USER_EQUIPMENT but i don't know how can i use it like i want.

I made something like this:

function getEquipment($name) { $query = "select * from equipments where name = '$name'"; $this->connect(); $res = $this->execute($query); $this->disconnect(); return $res; }

and then i called it like:

$name = $_SESSION['name']; include_once('DataAccess.php'); $da = new DataAccess(); $res = $da->getEquipment($name);

But i doesn't get the equipment by the name. Little help please?

Thanks.

@Allen's answer:

bool equals = a.Intersect(b).Count() == a.Union(b).Count()

is about arrays but as far as IEnumerable<T> methods are used, it can be used for Dictionary<K,V> too.

I'm having trouble getting to use the query mongodb.

I do not know if I could detail the method used is being sent an object, but is being rejected or sometimes the filter back empty.

it always returns me an error:

MongoError: query selector must be an object

The entry of the query is being thereby:

{ filter: 'f', limit: '5', page: '1', sort: '-posted' }

My server Route:

exports.findAll = function(req, res, next) { var locals = {}, section = req.params.section, query = req.query, filter = {}; if(query.filter) { filter = query.filter.replace(/"(\w+)"\s*:/g, '$1:'); filter = filter.replace(/["]/g, "'"); } console.log(filter); delete query.filter; async.series([ function(callback) { MongoClient.connect(url, function(err, db) { if (err) return callback(err); locals.collection = db.collection(section); callback(); }); }, function(callback) { locals.collection.count(filter, function (err, result){ if (err) return callback(err); locals.count = result; callback(); }); }, function(callback) { //var cursor = locals.collection.find(filter); var cursor = locals.collection.find(filter, req.query); // if(req.query.order) { // cursor = cursor.sort(); // } // // if(req.query.limit) { // cursor = cursor.limit(Math.abs(req.query.limit)); // if(req.query.page) { cursor = cursor.skip(Math.abs(req.query.limit) * --req.query.page); } // } cursor.toArray(function(err, docs) { if (err) return callback(err); locals.docs = docs; callback(); }); } ], function(err) { //This function gets called after the three tasks have called their "task callbacks" if (err) return next(err); // Here locals will be populated with 'count' and 'docs' res.json({ count: locals.count, data: locals.docs }); });

};

i change the function server, adn now my response is:

{ filter: {situation: 't'}, limit: '5', page: '1', sort: '-posted' }

And same error :( :(

Did you changed the password you use in the machine where the SQL server is installed? I experienced this before, and what I did was to reflect my new password to the SQL Server configuration, then restart the service.

Please also make sure the the TCP/IP setting is enabled in the SQL configuration settings.

If one class is specifically designed for validation purposes and another class is designed to contain instance-specific information, then there are three different approaches you can take.

1) Statically reference the validator (recommended):

<?php class Validation { public static function validateEmail($email) { return filter_var($email, FILTER_VALIDATE_EMAIL); } } class AccountManagement { public $email; public function __construct($email) { $this->email = $email; // Validate the e-mail. If not valid, an exception is thrown. if(!Validation::validateEmail($this->email)) { throw new InvalidArgumentException('$email argument supplied must contain a valid e-mail address'); } } }

2) Extend your instance class to inherit from your validation class

<?php class Validation { public function validateEmail($email) { return filter_var($email, FILTER_VALIDATE_EMAIL); } } class AccountManagement extends Validation { public $email; public function __construct($email) { $this->email = $email; // Validate the e-mail. If not valid, an exception is thrown. if(!$this->validateEmail($this->email)) { throw new InvalidArgumentException('$email argument supplied must contain a valid e-mail address'); } } }

3) Instantiate your validation class from within your instance class (NOT RECOMMENDED):

<?php class Validation { public function validateEmail($email) { return filter_var($email, FILTER_VALIDATE_EMAIL); } } class AccountManagement extends Validation { public $email; public function __construct($email) { $this->email = $email; $validator = new Validation; // Validate the e-mail. If not valid, an exception is thrown. if(!$validator->validateEmail($this->email)) { throw new InvalidArgumentException('$email argument supplied must contain a valid e-mail address'); } } }

Testing your implementation

Once you've chosen the method which best fits your needs (regardless of which one you choose), you can test it with the following code:

// Valid, should not throw an exception and should print success. try { $account = New AccountManagement('me@myself.com'); print "AccountManagement object successfully instantiated.<br />\r\n"; } catch(Exception $e) { print 'Error: Encountered ' . $e; } // Invalid, should throw an InvalidArgumentException exception try { $account = New AccountManagement('myself.com'); print "AccountManagement object successfully instantiated.<br />\r\n"; } catch(Exception $e) { print 'Error: Encountered ' . $e; }

Bonus Example:

Sometimes, you may want to specifically catch Validation errors, and let something take care of any other exceptions which may be encountered. In this case, we can create a special exception just for our validator, and allow the validator to be the one to throw the exception:

<?php class ValidationException extends Exception { // Will use default Exception behavior. } class Validation { public static function validateEmail($email) { if(!filter_var($email, FILTER_VALIDATE_EMAIL)) { throw new ValidationException('E-mail address supplied is not valid'); } } } class AccountManagement { public $email; public function __construct($email) { $this->email = $email; // Validate the e-mail. Validation::validateEmail($this->email); } } // Valid, should not throw an exception and should print success. try { $account = New AccountManagement('me@myself.com'); print "AccountManagement object successfully instantiated.<br />\r\n"; } catch(Exception $e) { print 'Error: Encountered ' . $e; } // Invalid, should throw an ValidationException exception try { $account = New AccountManagement('myself.com'); print "AccountManagement object successfully instantiated.<br />\r\n"; } catch(ValidationException $e) { print 'Error: Encountered ' . $e; }

11450737 0 Is Content Negotiation broken?

I recently got interested in web crawlers but one thing isn't a very clear one to me. Imagine a simple crawler that would get the page, extract links from it and queue them for later processing the same way.

How crawlers handle the case when certain link wouldn't lead to another page but to some asset or maybe other kind of static file instead? How would it know? It probably doesn't want to download this kind of maybe large binary data, nor even xml or json files. How content negotiation fall into this?

How I see content negotiation should work is on the webserver side when I issue a request to example.com/foo.png with Accept: text/html it should send me back an html response or Bad Request status if it cannot satisfy my requirements, nothing else is acceptable, but that's not how it works in the real life. It send me back that binary data anyway with Content-Type: image/png even when I'm telling it I only accept text/html. Why webservers work like this and not coercing the right response I'm asking for?

Is implementation of content negotiation broken or it's application's responsibility to implement it correctly?

And how does real crawlers work? Sending HEAD request ahead to check whats on the other side of a link sees as an unpractical waste of resources.

You should login your user again and only after that attach the file.I had similar situation when i took a picture using camera. I did this. Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivity(intent); CameraActivity was started and connection was lost, so you need to reconnect if you want to upload the file.

There is a config.inc.php under setup/frames, this is the one you are showing us but it's not the one that contains the configuration. Look at the main directory containing all the db_* and tbl_* scripts. However, phpMyAdmin is able to run without a config.inc.php.

Do you see a login panel with phpMyAdmin logo?

10784772 0 Drawing a line with a brush in iOS

there are so many posts here, were people ask how to draw lines with a brush in CGContext. The answer always is: Use a pattern. However, I tried this for some hours now and the main problem to me seems to be: It seems like CoreGraphics simply draws the pattern as a fill and then simply clips this pattern with the stroke of the path you specified. This leads to some bad looking tile-borders and it simply doesn't look as someone really draws something by hand. What I want is something were the brush is painted along the path, without any clipping. I basically want to move along the path and simply draw the brush image every x points, in distance, on the path, with the size of the brush. Is this somehow possible with CoreGraphics or is this just something you have to implement on your own?

//EDIT: Sorry, I thought it was clear what I tried by saying, I used a pattern. This is what I did so far:

struct CGPatternCallbacks patternCallback = {0, drawChalkPattern, NULL}; CGAffineTransform patternTransform = CGAffineTransformMakeScale(.25f, .25f); UIImage* brush = [UIImage imageNamed:@"ChalkBrush"]; CGPatternRef pattern = CGPatternCreate(NULL, (CGRect){CGPointZero, brush.size}, patternTransform, brush.size.width, brush.size.height, kCGPatternTilingConstantSpacingMinimalDistortion, true, &patternCallback); CGColorSpaceRef patternSpace = CGColorSpaceCreatePattern(NULL); CGContextSetStrokeColorSpace(context, patternSpace); CGFloat color[4] = {1.0f, 1.0f, 1.0f, 1.0f}; CGContextSetStrokePattern(context, pattern, color); CGContextDrawPath(context, kCGPathStroke);

and than this is the patternCallback function:

void drawChalkPattern(void * info, CGContextRef context) { UIImage* pattern = [UIImage imageNamed:@"ChalkBrush"]; CGContextDrawImage(context, (CGRect){CGPointZero, pattern.size}, [pattern CGImage]); }

Best regards, Michael

Rust has local type inference, so the type normally doesn’t need to be written; let x = 5; will suffice. x = 5; would be quite different, as it would not declare a variable x, and Rust very deliberately separates declaration and assignment.

It’s also actually let PATTERN = EXPR;, not just let IDENT = EXPR;, so removing the let keyword would cause grammatical ambiguity. A pattern could be mut x (making the variable binding mutable), it could be (a, b) signifying tuple unpacking, &c.

You only think i32 x = 5; makes sense because you’re used to languages like C++. Seriously, who came up with that idea? It makes more sense on purely philosophical grounds to have the type after the name than before, and having just the type to declare variables is silly too. All sorts of grammatical ambiguity there. Type inference, allowing you to omit the type altogether, is a much nicer approach all round.

39611555 0 How do I make this plugin return false and still chain

I have written a plugin which isn't finished yet I might add. All it does at the moment is to check if all inputs are empty. If any inputs are empty it puts a message under the input.

Now the plugin is suppose to return false if it fails.

The problem is chaining. The way it works at the moment it doesn't chain if I return false, because I am not returning base.

How do I make this plugin return false and still chain.

;(function($){ "use strict"; $.fn.valiDate = function(options){ var base=this; /*Adds the input on the page */ if(!$('#asi_validate').length) { $('.footer').before('<span style="border:1px solid black;background-color:#FFF;color:red;\ box-shadow: 5px 5px 5px #888888;padding:5px;position:absolute;width:auto;display:none;\ " id="asi_validate"></span>'); } var valid = true; var validatepos=$('#asi_validate'); base.check_key= function(){ $(this).keyup(function(){ validatepos.fadeOut(50); }); } base.check= function() { $('input').each(function() { if (this.value == '') { var cell=$(this); var position = cell.offset(),maxLength=cell.val().length; validatepos.css('left',position.left), validatepos.css('top',position.top+(cell.outerHeight()+2)), validatepos.fadeIn(100), validatepos.html('This field is required'); valid = false; return false; } }); } base.check_key(); base.check(); if (valid === false) { return false; } return base; }; })(jQuery);

In XAML a string is so easily converted to a color that you hardly realize they are very different types. In C# you will have to convert it explicitly. Luckily there is a built-in class that can do that:

string colorName = (string) listColor.SelectedItem; Color colorValue = ColorConverter.ConvertFromString(colorName);

38488612 0 Search all tables to display a row that contains a specific string/ id

I am fairly new to PostgreSQL. I want to search all tables that contain a string/id and display the row that holds the string/id. This is what I have so far:

`CREATE OR REPLACE FUNCTION search_columns( needle text, haystack_tables name[] default '{}', haystack_schema name[] default '{public}' ) RETURNS table(schemaname text, tablename text, columnname text, rowctid text) AS $$ begin FOR schemaname,tablename,columnname IN SELECT c.table_schema,c.table_name,c.column_name FROM information_schema.columns c JOIN information_schema.tables t ON (t.table_name=c.table_name AND t.table_schema=c.table_schema) WHERE (c.table_name=ANY(haystack_tables) OR haystack_tables='{}') AND c.table_schema=ANY(haystack_schema) AND t.table_type='BASE TABLE' --AND c.column_name = "id" LOOP EXECUTE format('SELECT ctid FROM %I.%I WHERE cast(%I as text) like %L', schemaname, tablename, columnname, needle ) INTO rowctid; IF rowctid is not null THEN RETURN NEXT; END IF; END LOOP; END; $$ language plpgsql; select * from search_columns('%3172226%','{}');` I run the code above and the tables that contain 3172226 get displayed. Let's assume I found that tablenamexxx contains the id. Then I run the following command: `select * from public.tablenamexxx where ctid='(x,x)';`

The command above displays the row from tablenamexxx

I have two problem: 1) I want to alter my code so I don't have to type in the found tablenames (that contain 3172226). I want my code to find what tables contain the id and directly display the row that has the id.

2)There are two tables that have the id (3172226). I want to display both the tables together. My guess is using union all.

Any help would be appreciated! Thank you

My understanding is that the user can extend localstorage but the website can't (by design). You simply need to catch the error in Javascript and show the user a dialog requesting they increase their storage limit - preferably providing some instructions for major browsers.

EDIT: Perhaps not so simple. It seems some browsers don't allow the user to increase the storage size. Google seems convinced the localStorage API doesn't scale well to large files and developers should consider IndexedDB instead.

I could not place a comment, but try to look for the image view in your activity. It could be because your code is overriding it from there.

also limit the size of your imageview from the layout xml to make sure its loaded correctly.

And from experience with large photos, they normally not loaded easily on an emulator. so try smaller image as a last step.

3492763 0 Active Directory User Group Membership

I am trying to get a users group membership and limiting the results to those that match a string, ie I am only interested in the users group membership where the group begins with "test-".

The following is what I have been playing around with, even though the user is apart of several groups that match the search string, the If statement is not returning True on any of them.

Private Function GetGroups(ByVal userName As String) As Collection Dim Groups As New Collection Dim intCount As Integer Dim entry As DirectoryEntry = ADEntry() Dim mySearcher As DirectorySearcher = New DirectorySearcher(entry) Dim arrList As New ArrayList() ' Limit the search results to only users mySearcher.Filter = "(&(ObjectClass=User)(CN=" & userName & "))" ' Set the sort order mySearcher.PropertiesToLoad.Add("MemberOf") Dim searchResults As SearchResultCollection = mySearcher.FindAll() MessageBox.Show(searchResults.Count) If searchResults.Count > 0 Then Dim group As New DirectoryEntry(searchResults(0).Path) For Each member As Object In group.Properties("MemberOf") MessageBox.Show("Pre: "+ member) 'This message box returns all the groups the user is apart of. If group.Properties("memberOf").Contains("test-") = True Then MessageBox.Show(member) ' This message box never shows End If Next End If Return Groups End Function

Is there any way of applying a search or If statement agains an Object where the constraint is a wildcard?

The groups I am looking for could be one of about 60 (this amount does increase and decrease as staff leave).

I am using VB.NET 2.0.

What I'm trying to achieve is make a chrome extension run in the background, and every minute it'll redirect to google.com and then a minute later redirect to stackoverflow.com and so on continuously until the icon is clicked by the wrench icon where most of the extensions are.

However I only know on how to redirect a page using window.location.replace("http://google.com");

I'm still learning on how to develop chrome extensions, and just making some simple stuff for a learning process. I started learning from this tutorial, and tried a couple things out, and now I wanna figure out how to get something like this to work with it running in the background.

What you want to do is sort an array, whose elements are hash, based on the hash's "code" value.

entries.sort { |a, b| a["code"] <=> b["code"] }

And also, I would suggest you do this in your controller instead of view.

EDIT:

Or you could do sort the tag first, then mapping them into an Array

Ci::Canonical::Language::Tag.sort_by do |a, b| a.code <=> b.code end.map do |tag| { "code" => tag.code, "description" => tag.description, "ordinal" => tag.value, } end

11526627 0 bounding box of n glyphs, given individual bboxes and advances

For specific reasons, I'm implementing my own font rendering, and an algorithm to compute the bounding box of a text by using bounding boxes of single glyphs, together with the respective advance, is needed. For clarification see this illustration:

enter image description here

For every of these N glyphs is given the relative bbox relative to the origin (xmin, xmax, ymin, ymax), and the advance (pseudocode):

int xmin[N], xmax[N], ymin[N], ymax[N], adv[N];

I will give the answer myself if noone bites.

Theres no formal difference between 'Text classification' and 'Sentence classification'. After all, a sentence is a type of text. But generally, when people talk about text classification, IMHO they mean larger units of text such as an essay, review or speech. Classifying a politician's speech into democrat or republican is a lot easier than classifying a tweet. When you have a lot of text per instance, you don't need to squeeze each training instance for all the information it can give you and get pretty good performance out a bag-of-words naive-bayes model.

Basically you might not get the required performance numbers if you throw off-the-shelf weka classifiers at a corpora of sentences. You might have to augment the data in the sentence with POS tags, parse trees, word ordering, ngrams, etc. Also get any related metadata such as creation time, creation location, attributes of sentence author, etc. Obviously all of this depends on what exactly are you trying to classify.. the features that will work out for you need to be intuitively meaningful to the problem at hand.

In lcmm(*range(1,5)) you're unpacking the iterable range(1, 5) with * so you're actually calling lcmm(1, 2, 3, 4). In other words, there are five arguments that don't have names but they're in order and they're passed in those positions. In the function def lcmm(*args): the * captures the positional arguments into args. This means args gets the value (1, 2, 3, 4). That explains why you're getting the same as reduce(lcm, range(1,5)) because that's the same as reduce(lcm, args) when args = (1, 2, 3, 4).

When you're calling lcmm(range(1,5)) it means you're passing [1, 2, 3, 4] as your argument. This is the only positional argument so at def lcmm(*args): the value of *args still captures all positional arguments. But because there's only one positional arguments the value of args becomes ([1, 2, 3, 4],). That's a tuple with one value in it, namely [1, 2, 3, 4]. This gives you a different result when lcm computes the return value.

Two issues I can see here:

The empty() and remove() methods of jQuery actually do quite a bit of work. See John Resig's JavaScript Function Call Profiling for why.
The other thing is that for large amounts of tabular data you might consider a datagrid library such as the excellent DataTables to load your data on the fly from the server, increasing the number of network calls, but decreasing the size of those calls. I had a very complicated table with 1500 rows that got quite slow, changing to the new AJAX based table made this same data seem rather fast.

boost::reference_wrapper (which is what boost::ref returns) does not overload operator(). You can use it with boost::bind, which has special treating for it (not using ref would make bind copy the provided function object).

But for_each returns the function object it invokes the stuff on. So just do this

between_1_and_10 val; val.d = 4; val = for_each(lst.begin(), lst.end(), val); printf("rg");

It will call the stuff on the copied val, and return the function object as it's after the last invocation.

Just to tell you where you might use boost::ref, because you seem to misuse it. Imagine a template that takes its parameter by value, and calls another function:

void g(int &i) { i++; } template<typename T> void run_g(T t) { g(t); }

If you now want to call it with a variable, it will copy it. Often, that's a reasonable decision, for example if you want to pass data to a thread as start parameters, you could copy it out of your local function into the thread object. But sometimes, you could want not to copy it, but to actually pass a reference. This is where boost::reference_wrapper helps. The following actually does what we expect, and outputs 1:

int main() { int n = 0; run_g(boost::ref(n)); std::cout << n << std::endl; }

For binding arguments, a copy is a good default. It also easily makes arrays and functions decay to pointers (accepting by reference would make T be possibly an array/function-type, and would cause some nasty problems).

Have a look at DBIx::Mint You will need to add a role to your Moo classes

with 'DBIx::Mint::Table';

And also write a schema file. This schema file should have all information on classes you're going to use (class-to-table mapping, relationship to other tables/classes). No need to write schema file for each Moo class.

As of right now, you cannot retrieve a permanent access token. You have 2 options that come close.

The first is to request a "refresh" token when using the standard OAuth flow. That's what you're doing by sending "duration" as "permanent" in your code. The refresh token can be used to automatically retrieve new 1 hour access tokens without user intervention; the only manual steps are on the initial retrieval of the refresh token.

The second alternative, which applies only when writing a script for personal use, is to use the password grant type. The steps are described in more detail on reddit's "OAuth Quick Start" wiki page, but I'll summarize here:

Create an OAuth client (under https://www.reddit.com/prefs/apps) with type = "script"
Make a request to https://www.reddit.com/api/v1/access_token with POST parameters grant_type=password&username=<USERNAME>&password=<PASSWORD>. Send your client ID and secret as HTTP basic authentication. <USERNAME> must be registered as a developer of the OAuth 2 client ID you send.

1330927 0 Opinion Polling and PHP

Okay, so I want to make a polling site but it doesn't work like a typical poll.

Here's how I would like mine to operate:

User registers and is sent confirmation email Once they confirm they can log in From there they get to one giant poll with several topics but apposed to choosing one topic, they would have 20 or so "tokens" where they may distribute them among each topic as desired. These users then save their votes, and it goes into a database where results can then be displayed. These 20 tokens would replenish once a week, or month, or bi-weekly or something.

This is the basic idea. I'm not asking if this is a good idea. I would just like to know if there is a poll plugin/add-on type thing that I can just install on my site that would support this or if this would have to be custom made?

Additional features on this site would be that there would be a different section, where users would vote on a typical poll. This poll would ask what topics should be added to the first main poll.

If a plugin exist that would support this could someone tell me or it.

Or if this were custom made. How intense would it be? I have a novice understanding of PHP and MySQL is this something I could do?

I appreciate the help,

Re-read the $set documentation https://docs.mongodb.org/v3.0/reference/operator/update/set/ It specifically says it will replace what is there. So it doesn't care if a document exists or not that's why it doesn't return the error. you need additional operators to reject the query if it exists and is the same.

edit/update to below comment

You have to trigger the error in order to know if the DB as the collection already and if it's up to date. So an additional operator is required to check if the collection found already has the updated information. MongoDB uses operators represented with $ so $gt or $lt or $nor (greater than , less than, Select everything but this) there's more but i'll let you explore the possibilities. https://docs.mongodb.org/v3.0/reference/operator/query/nor/

this line needs to trigger the error based on your expressions and operators. when you get that working don't just throw the error allow the program to continue to the next because this error isn't meant to break (throw) on that error it's only there to tell you hey the DB has this and it's updated, and on error will let you know nothing was done.

collection.updateOne(query, {"$set": data},{w: "majority"},function (err,result){ console.error(err);console.log(result); });

For sorting numbers you can use counting sort algorithm: you have numbers of limited range, from 0 to 999. So, you can count how many times each number occurred in input file:

int[] count = new int[1000]; //depending of scope, maybe you need to fill array with zeroes ... int number = ...;//read number from file; count[number]++;

Now, in order to output it as sorted, you just need two loops like this:

for (int i = 0; i < 1000; ++i) { for (int j = 0; j < count[i]; ++j) { System.out.println(i); } }

I wrote this just to make sure idea is clear, although your task doesn't require to output them all. Now, let's imagine you read these two numbers;

int start, finish = 0; //value read from input

We gonna modify the loops above like this:

int counter = 0; for (int i = 0; i < 1000; ++i) { for (int j = 0; j < count[i]; ++j) { if ((counter >= start) && (counter < finish)) {//or maybe <=, depending on what exactly do you need System.out.println(i); } counter++; if (counter > finish) { //we finished, further iterations are waste of CPU time break(2); } } }

This method is not optimal, but easy to understand and implement. For more fast solutions, you may want to get rid of inner loop, replacing it with logic to add count[i] to counter at once and detecting moment when we need to start output.

19506163 0 How to correctly chain conditional(?) promises with Q.js

I've still not quite got a complete understanding of promises so apologies if this is a simple misunderstanding.

I have a function for deleting an item on a page but I have a specific behaviour depending on the state of the page. Psuedo code-wise it's something like this:

Does the page have changes? If yes - prompt to save changes first If yes - save changes If no - exit function If no - continue Prompt to confirm delete If yes - delete item and reload data If no - exit function

Hopefully that makes sense. Essentially if there are changes, the data must be saved first. Then if the data has been saved, or if there were no changes to begin with, prompt the user to confirm deletion. The problem is I'm using durandal and breeze, and I can't seem to chain the promises they return together correctly.

My function currently looks like this, which I know is wrong, but I'm struggling to work out where to fix it.

if (this.hasChanges()) { app.showMessage('Changes must be saved before removing external accounts. Would you like to save your changes now?', 'Unsaved Changes...', ['Yes', 'No']) .then(function (selectedOption) { if (selectedOption === 'Yes') { return this.save(); } else { Q.resolve() } }); } app.showMessage('Are you sure you want to delete this item?', 'Delete?', ['Yes', 'No']) .then(function (selectedOption) { if (selectedOption === 'Yes') { item.entityAspect.setDeleted(); datacontext.saveChanges() .then(function () { logger.logNotificationInfo('Item deleted.', '', router.activeInstruction().config.moduleId); Q.resolve(this.refresh(true)); }.bind(this)); } }.bind(this));

The app.showMessage call from durandal returns a promise, then the this.save returns a promise, and finally the this.refresh also returns a promise.

So I guess I need to check the hasChanges, then if necessary call save, and resolve it. Then after that conditional section has finished resolving, call the second prompt, and then resolve all the promises within that.

I'm sorry I don't think this is super clear, but that's also I think coming from the fact I'm not completely following the chains here.

Any help much appreciated! Thanks.

Basically, you are temporarily assigning to the object reference to variable pi. The variable is overwritten, but the object is not. It safely gets added to your list for any future use.

34183531 0 Canvas.DrawBitmap unexpected result(BUG or strange behaviour) Xamarin Android

So i have an problem with method of Canvas.DrawBitmap(), that draws unexpected result.
Lets see my example:
Source image

I have two cases(just for test):

I want to draw Red rectangle from 0,0 and give for him size 1/4 of image,also i want to draw this bitmap in same size(1/4) and put to Bottom.Right place.
Draw again Red rectangle with same conditions(starts from Top.Left(0,0) and size 1/4 of image) and draw part of bitmap and shows as Rectangle with 1/4 size(Bottom.Right).

Case #1

i'm doing this:

//source imageview Source.SetImageResource(Resource.Drawable.lena30); //bitmap bt = ((BitmapDrawable)Source.Drawable).Bitmap.Copy(Bitmap.Config.Argb8888, true); //second imageview, where i fill result Draw.SetImageBitmap(bt); can = new Canvas(bt); Paint paint = new Paint(); paint.Color = Color.Red; paint.SetStyle(Paint.Style.Fill); //draw Red Rect with 1/4 size and locate Top.Left can.DrawRect(0,0,bt.Width/2,bt.Height/2,paint); //redraw new bitmap(all subset) and locate to Bottom.Right with 1/4 size can.DrawBitmap(bt, null, new Rect(bt.Width/2, bt.Height / 2, bt.Width, bt.Height), null);

and the result is :

Case #2

same,but getting now part of bitmap(not full subset of bitmap):

 //source imageview Source.SetImageResource(Resource.Drawable.lena30); //bitmap bt = ((BitmapDrawable)Source.Drawable).Bitmap.Copy(Bitmap.Config.Argb8888, true); //second imageview, where i fill result Draw.SetImageBitmap(bt); can = new Canvas(bt); Paint paint = new Paint(); paint.Color = Color.Red; paint.SetStyle(Paint.Style.Fill); //draw Red Rect with 1/4 size and locate Top.Left can.DrawRect(0,0,bt.Width/2,bt.Height/2,paint); //redraw new bitmap(not full,only part of Source Rectangle) and locate to Bottom.Right with 1/4 size can.DrawBitmap(bt, new Rect(bt.Width/2,0,bt.Width,bt.Height), new Rect(bt.Width/2, bt.Height / 2, bt.Width, bt.Height), null);

So i cant understand,why that happens?(Why image no scaling to fit size and duplicate Rectangles!?).
Any ideas? Thanks!

C allows you to not specify any arguments in a declaration (function prototype), and the compiler will parse it as the function takes an unknown number of unspecified arguments. In C++ a function declaration without arguments means that the function doesn't take any arguments, it's the same as using the argument void. You need to specify the arguments in the declaration.

Which leads to your error: It's impossible to answer why you get the errors when you add the arguments as the question doesn't show more context, but an educated guess is that you miss some header file. Do you include the header file where XDR is declared? Do you include <stdio.h> (for FILE)?

It's because you are using Dictionary.prototype on your methods. Replace them with this and it will work:

this.put = function() this.firstKey = function() this.lastKey = function() ...

Using the this keyword, you are assigning methods to your Dictionary [sort of] class. You are simply making the functions public. If you look at your functions such as removeItemArray() then these are private and only accessible from within the object.

Prototype works differently. This is a nice quote from an answer to this question about prototype:

The protoype is the base that will be used to construct all new instances and also, will modify dinamically all already constructed objects because in Javascript objects retain a pointer to the prototype

The purpose of prototype is to give the ability to add methods to an object at runtime. This may seem somewhat of an alien concept if you're coming from classical OOP languages, where you traditionally pre-define a class and its methods.

Have a look at the other answers in that question which explain prototype really well.

As the error says, you cannot view the keys of a boolean, aka, True.viewkeys() does not work. Change your default dictionary's to be empty, leaving:

def merge_many_dics(dic1,dic2,dic3={},dic4={},dic5={},dic6={},dic7={},dic8={},dic9={},dic10={}): """ Merging up to 10 dictionaries with same keys and different values :return: a dictionary containing the common dates as keys and both values as values """ manydics = {} for k in dic1.viewkeys() & dic2.viewkeys() & dic3.viewkeys() & dic4.viewkeys() & dic5.viewkeys() & dic6.viewkeys()\ & dic7.viewkeys() & dic8.viewkeys() & dic9.viewkeys() & dic10.viewkeys(): manydics[k] = (dic1[k], dic2[k],dic3[k],dic4[k],dic5[k],dic6[k],dic7[k],dic8[k],dic9[k],dic10[k]) return manydics

Here is an implementation in which you create a list for every key and add each item, I'm sure it can be optimized a lot more, but it's very readable:

def merge_many_dicts(*args): """ Merging all dictionaries suposing all dictionaries share keys :return: a dictionary containing the common dates as keys and both values as values """ manydicts = {} for k in args: for key in k.iterkeys(): manydicts[key] = [] for k in args: for key, value in k.iteritems(): manydicts[key].append(value) return manydicts

A pointer is not a variable. A pointer is a value.

A variable, in C, designates a storage location, and a value can be stored in that location. Thus, if you have a variable a declared with int a, then a is a variable in which an integer value can be stored. If you have a variable int *x, then x is a variable in which a pointer to an integer value can be stored.

The address of a storage location can be obtained using the & operator. E.g., &a is the address of the storage location designated by a, or the address of a, and can be stored in (among other things) a variable of the corresponding type. Thus you can have:

int a = 42; /* a is a variable of type int, and has value 42 */ int* x = &a; /* x is a variable of type int*, and has value &a */

Although analogies in programming are often dangerous, you might think of things like page numbers in a book. The page number of a page is not the same thing as the page, but page numbers can still be written down on pages. E.g., the table of contents page has lots of page numbers written down on it. Thus:

actual_page p = ...; /* a page structure */ page_number n = &p; /* a page number */

You seem to have two questions.

The second is the more specific question regarding AjaxControlToolkit.dll. For that, take a look at ERROR Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies.

As to your original question, as long as you only need to deploy the DLL (in other words, you don't need to run an install program, modify the web.config, etc), the way to go is to place your DLL into your WSP solution package. This is easier than ever with Visual Studio 2010.

38367304 0 Confusion over behavior of Publish().Refcount()

I've got a simple program here that displays the number of letters in various words. It works as expected.

static void Main(string[] args) { var word = new Subject<string>(); var wordPub = word.Publish().RefCount(); var length = word.Select(i => i.Length); var report = wordPub .GroupJoin(length, s => wordPub, s => Observable.Empty<int>(), (w, a) => new { Word = w, Lengths = a }) .SelectMany(i => i.Lengths.Select(j => new { Word = i.Word, Length = j })); report.Subscribe(i => Console.WriteLine($"{i.Word} {i.Length}")); word.OnNext("Apple"); word.OnNext("Banana"); word.OnNext("Cat"); word.OnNext("Donkey"); word.OnNext("Elephant"); word.OnNext("Zebra"); Console.ReadLine(); }

And the output is:

Apple 5 Banana 6 Cat 3 Donkey 6 Elephant 8 Zebra 5

I used the Publish().RefCount() because "wordpub" is included in "report" twice. Without it, when a word is emitted first one part of the report would get notified by a callback, and then the other part of report would be notified, double the notifications. That is kindof what happens; the output ends up having 11 items rather than 6. At least that is what I think is going on. I think of using Publish().RefCount() in this situation as simultaneously updating both parts of the report.

However if I change the length function to ALSO use the published source like this:

var length = wordPub.Select(i => i.Length);

Then the output is this:

Apple 5 Apple 6 Banana 6 Cat 3 Banana 3 Cat 6 Donkey 6 Elephant 8 Donkey 8 Elephant 5 Zebra 5

Why can't the length function also use the same published source?

update may 27:

we just released an update (version 9.0.1) to fix the incompatibility I mentioned in my first edit.
Please update your dependencies and let us know if this is still an issue.

Thanks!

original answer May 20:

The issue you are experiencing is due to an incompatibility between
play-services / firebase sdk v9.0.0 and com.android.support:appcompat-v7 >= 24
(the version released with android-N sdk)

You should be able to fix it by targeting an earlier version of the support library. Like:

compile 'com.android.support:appcompat-v7:23.4.0'

17113057 0 Generate Pinterest Share Button That Specifies URL

I am trying to create a "pinterest share" button, but am running into a snag.

Currently, I have the pinterest button (generated from their Widget Builder) appearing in a Lightbox. (For certain reasons, it must appear this way.)

The issue is the Lightbox code has direct linking on it, so the code for the lightbox window is something like: www.domain.com/#/social/4

Pinterest is picking up that URL (which has no images since it's just the lightbox) instead of the URL for the main page (www.domain.com).

Does anyone know how I can specify the exact URL to share via the pinterest button?

I have read some posts that said doing this would work:

<a href="http://pinterest.com/pin/create/button/?url=http://www.domain.com" class="pin-it-button" count-layout="none"><img src="//assets.pinterest.com/images/PinExt.png" alt="Pin it" / ></a> <script type="text/javascript" src="http://assets.pinterest.com/js/pinit.js"></script>

However, specifying the URL does not seem to work at all. It appears to be totally ignored and has no impact.

Any ideas?

Thanks in advance!

19221669 0 Is it possible to set a border to overlay (like in photoshop)

I am having a quite exotic question: I am currently working on a "borderless" WPF Application. I successfully removed the standard windows window controls and added my own. Now I wanted to add a border to the programm. But I don't want the border to have specifc color, I want it to be in some kind of overlay mode like when you set a layer in photoshop to overlay. You can see what I mean in an example:

Photoshop Mookup

I really want it to look like on the left. But unfortunately I really have no idea how. Basically what the overlay does is that it takes the background color and it makes it a bit darker. Do you have any suggestions what I could do?

Edit: Here is a better picture of the effect

Photoshop Mookup2

Edit2 : So, as a short explanation because it may not be as clear as I have hoped: I am not talking about a semi-transparency. I know how to do that. The right box in both images uses that. It has a black-semitransparent look. While on the left I set the border to "overlay" mode. As you can see it gets darker but also a bit stronger in color.

This should be doable in O(n) time... A hash map is usually implemented as a large bucket array, the bucket's size is (usually) directly proportional to the size of the hash map. In order to retrieve the key set, the bucket must be iterated through, and for each set item, the key must be retrieved (either through an intermediate collection or an iterator with direct access to the bucket)...

**EDIT: As others have pointed out, the actual keyset() method will run in O(1) time, however, iterating over the keyset or transferring it to a dedicated collection will be an O(n) operation. Not quite sure which one you are looking for **

Putting @j08291's comment into an answer.

You can only have one element with an ID. Change them to classes, and you'll need to do some tree traversing to get the reference to the correct form elements to show and hide http://jsfiddle.net/pcUBr/

Also, your CSS class names (show,hide) aren't very semantic. Try the following

CSS

.question_form { display: none; } .question_form.current { display: inline; }

$(".button").click(function(e){ var form = $(e.target).closest('form'); form.toggleClass("current"); form.next().toggleClass("current"); });

HTML

<form class="question_form current" > <img src="image1.png" class="current_image" alt=""> <h3 class="question"> Question 1: </h3> <hr> <input type="radio" name="q1" value="q1-a">Answer 1 <br> <input type="radio" name="q1" value="q1-b">Answer 2 <br> <input type="radio" name="q1" value="q1-c">Answer 3 <br> <br> <input name="button" type="button" class="button" value="Next"> </form>

Just Change the CSS of the ul.

Hide List- $( "#mylist" ).css("display","none");

Show List- $( "#mylist" ).css("display","block");

I fixed my problem using a new function in my controller.

My controller:

$data['counts'] = $this->bedrijven_model->bedrijf_categorie();

My model:

function bedrijf_categorie() { $sql = " SELECT count(b.idbedrijven) as ItemCount, c.Categorie as Categorie FROM `bedrijven` b INNER JOIN `bedrijfcategorieen` bc ON bc.idbedrijven = b.idbedrijven INNER JOIN `categorieen` c ON c.idcategorieen = bc.idcategorieen GROUP BY c.idcategorieen "; $query = $this->db->query($sql); return $query->result_array(); }

my views:

 <?php echo '<ul>'; foreach($counts as $count){ echo '<li>'; echo '<a href="'.base_url().'home/categorieen/'.$count['Categorie'].' ">' .$count['Categorie']. '</a>'; echo nbs(1); echo '('; echo $count['ItemCount']; echo ')'; echo '</li>'; } echo '</ul>'; ?>

Anyway. thanks people who helped.

12587271 0 re-initiate a jQuery plug-in after dynamically inserting content

I have a jQuery tabs plug-in which works well... However I have a lightbox (also dynamicaly generated) that allows users to choose content which then gets shown in tabs.

This works fine if the user chooses content, leaves the page and comes back.. however i want the tabs to work as soon as the user finishes selecting content.

I have tried the usual .delegate() tags, but which event do I attach them to? I have tried doing it on the 'save' button on the lightbox but as this is also dynamically generated it doesn't appear to work.

Any ideas?

Thanks!

There is a problem with different number of arguments.

The simplest way is to use data type for "parameters". And to use data type for "result".

And to use just pattern-matching instead of class.

Something like that:

type GreenMix a = (Scalar a, Complex (Scalar a)) data ResultType a = Clomb (Scalar a) | Lrenz (Complex (Scalar a)) | Mix (GreenMix a) data Gauge a = Gauge1 (Scalar a) (Scalar a) | Gauge2 (Scalar a) (Scalar a) (Scalar a) greenF :: (Scalar a -> a) -> (Scalar a -> a) -> Gauge a -> Result a greenF f1 f2 (Gauge1 g1 g2) = Clomb $ greenF_Gauge1 f1 f2 g1 g2 greenF f1 f2 (Gauge2 g1 g2 g3) = Lrenz $ greenF_Gauge2 f1 f2 g1 g2 g3

I think of file descriptors as (indirect, higher-level) pointers to opaque file objects maintained by the kernel.

Normally, when you deal with objects maintained by a library, you pass to the library pointers to objects that you're not supposed to dereference and manipulate yourself.

For kernel objects, this it's not just that you're not supposed to manipulate them yourself -- you literally can't because they live in a different address space that's not at all accessible to you. And because they live in a different address space, pointers wouldn't be a meaningful way of referring to them.

You need a token or handle which the kernel would internally resolve to a pointer that's meaningful in the kernel address space. File descriptors are such tokens in integer form.

For the kernel:

your_process_id + your_file_descriptor => kernels_file_object_pointer

(or an EBADF error if a given filedescriptor may not be resolved to a file object pointer for the given process)

No, there is no such functionality. Instead of managing cluster with advisory messages, kafka relies on zookeeper and whenever some action is required (e.g. delete topic, perform rebalance) it creates appropriate "command" node in zk.

Having said this, kafka exposes a lot of it's underpinnings as JMX accessible statistics.

In general you should avoid performing multiple calls with aov and rather use a mixed effects linear model.

You can find several examples in this post by Paul Gribble

I often use the nlme package, such as:

require(nlme) model <- lme(dv ~ myfactor, random = ~1|subject/myfactor, data=mydata)

Depending on the situation you may run in more complex situations, I would suggest to have a look at the very clear book by Julian Faraway "Extending the Linear Model with R: Generalized Linear, Mixed Effects and Nonparametric Regression Models".

Also, you may want to ask on CrossValidated if you have more specific statistical questions.

I am in the process of writing my first REST service, so I am no expert, but in my opinion, I think it would be best to use a GET request, since that is exactly what you are doing -- getting data from the server. This will make it easier for other developers to support the app, instead of trying to figure out why you used PUT for a basic data retrieval.

If possible, I suggest that you try casting the UserSearchDTO XML as a string on the client and passing it to the GetUsers method as a string, then load the string into an XmlDocument() on the server and parse it into the DTO. Then your method signature would look like:

MyResponse GetUsers(string userSearchXmlString, int pageno, int totalrecords);

If you use copy-on-write collections it will work; however when you use list.iterator(), the returned Iterator will always reference the collection of elements as it was when ( as below ) list.iterator() was called, even if another thread modifies the collection. Any mutating methods called on a copy-on-write–based Iterator or ListIterator (such as add, set, or remove) will throw an UnsupportedOperationException.

import java.util.List; import java.util.concurrent.CopyOnWriteArrayList; public class RemoveListElementDemo { private static final List<Integer> integerList; static { integerList = new CopyOnWriteArrayList<>(); integerList.add(1); integerList.add(2); integerList.add(3); } public static void remove(Integer remove) { for(Integer integer : integerList) { if(integer.equals(remove)) { integerList.remove(integer); } } } public static void main(String... args) { remove(Integer.valueOf(2)); Integer remove = Integer.valueOf(3); for(Integer integer : integerList) { if(integer.equals(remove)) { integerList.remove(integer); } } } }

Like you said, after navigating away from original page you're losing track of what windows you may have opened.

As far as I can tell, there's no way to "regain" reference to that particular window. You may (using cookies, server side session or whatever) know that window was opened already, but you won't ever have a direct access to it from different page (even on the same domain). This kind of communication between already opened windows may be simulated with help of ajax and server side code, that would serve as agent when sharing some information between two windows. It's not an easy nor clean solution however.

you need to start it using the IP of the VM or the 0.0.0.0 IP. something like this should work

Format(PreCalcCurrentMonth,"\#mm\/dd\/yyyy\#") ensures that your date is converted to a string in US date format #mm/dd/yyyy#, whatever your regional settings. # is the date separator.

39797660 0 C free memory from struct array

The assignment is to create a struct array with 10 elements as "students" and each have a score and an ID. There are some things I am not allowed to change in the code (like anything in main).

#include <stdio.h> #include <stdlib.h> struct student* allocate(){ struct student* array = malloc(10 * sizeof(struct student)); return array; } void deallocate(struct student* stud){ int i = 0; for(;i<10;i++) free(&stud[i]); }

So this compiles fine and the rest of the code runs fine but then the core dumps when it gets to the free(). Also, this is the main that my professor gave me and told me not to change. There was no call to the deallocate function so now I am wondering if it automatically gets called when main is done or if he left it out by mistake. I added it in because I think that seems reasonable.

int main(){ struct student* stud = allocate(); generate(stud); output(stud); sort(stud); for(int i=0;i<10;i++){ printf("%d %d\n", stud[i].id,stud[i].score); } printf("Avg: %f \n", avg(stud)); printf("Min: %d \n", min(stud)); deallocate(stud); return 0; }

33745378 0 R connection to Redshift using AWS driver doesn't work but does work with Postgre driver

I am trying establish a connection to my redshift database after following the example provided by AWS https://blogs.aws.amazon.com/bigdata/post/Tx1G8828SPGX3PK/Connecting-R-with-Amazon-Redshift. However, I get errors when trying to establish the connection using their recommended driver. However, when I use the Postgre driver I can establish a connection to the redshift DB.

AWS says their driver is "optimized for performance and memory management", so I would rather use it. Can someone please review my code below, and let me know if they see something wrong? I suspect that I am not setting the URL up correctly, but not sure what I should be using instead? Thanks in advance for any help.

Whenever you declare a variable in XSLT 1.0 without @select, but with some content template, the variable type will be of Result Tree Fragment. The variable holds the root node of this tree fragment.

So, with this:

<xsl:variable name="source"> <xsl:copy-of select="$currentPage" /> </xsl:variable>

You are declaring $source as the root of a RTF containing the copy of the nodes (self and descendants) in $currentPage node set.

You can't use / step operator with RTF. That's why you are ussing node-set extension function.

But, when you say:

node-set($source)/ancestor-or-self::*

This will be evaluate to an empty node set, because a root node hasn't ancestors an it's not an element.

EDIT: If you have two node sets, and you want to declare a variable with the content of one of the two node sets depending on some condition, you could use:

<xsl:variable name="current" select="umbraco.library:GetXmlNodeById($source)[$source > 0] |$currentPage[0 >= $source]" />

34738139 0 Dotnetopenauth oAuth 2.0 server example - how does it work?

Can someone give me some help? I can't undestarnd how OAuth sample works.. and you?

I'm trying to understand the example of dotnetopenauth. I want to create my own oAuth 2.0 server and I'd like to study these examples.

If I run the OAuthConsumerWpf, I see a screen like this:

where, as you can see, in the Generic 2.0 tab it asks me for some urls. I think, like for the tab WCF sample, that I have to run another project of the examples zip, but I don't know which.

I have tried almost all, and nothing worked.

This is the list of the project in the zip:

Which one of those have I to run like oAuth 2.0 server?

I thought it is "OAuthAuthorizationServer", but it ask for a openID server url and it doens't seem to be the right one, although it is under the OAuth folder.

Do you have done it before? How?

Further, none of the project I've started binds on the port 18916.

WHAT DO I NEED?

I need someone tells me which one of these projects is the OAuth 2.0 server to be used with the OAuthConsumerWpf application, as I said above. In the wpf project I've found the client I need to study, but which is the server?

UPDATE: I think there is something incomplete in the samples.. or not? I have tried all of them, but nothing... do you have any hints?

Is there a way to set a variable globally in node.js on a per domain-like basis? I say domain-like because at first I though of creating a domain and attaching a value to it so any piece of code that runs inside the domain will have access to it. The code would have looked similar to this:

var myDomain = domain.create() myDomain.someVariable = 1; myDomain.run(function () { console.log(domain.getCurrentDomain().someVariable); });

Unfortunately, that's not how domains work and can be used. Is there something similar to this that can be done however?

Having nested scopes is not a solution because there's multiple files involed.

There is also another alternative, this one consists of deleting the subpanel and creating a new one.

The issue is with this line

dynamic var environment = RLMObject(object: PSTChannelEnv.className())

It just needs to be

dynamic var environment: PSTChannelEnv

The reason we have objectClassName... is because you are creating an array with type objectClassName. When doing a to-one relationship, you already know the object class, so you can set the type directly.

Here are more docs on the setting up your models in Realm

We should throw an error though when you try to do something like this. Thanks for pointing that out!

@(testForm: Form[Test], areas: List[AreaDefinition]) @import helper._ @main("Test") { @form(routes.TestController.newTest()) { <table border="0" id="areasensor_table"> <tr id="areasensor_row0"> <td> <div id="wrapperForArea"> <select id="selectedArea"> @for(area <- areas) { <option value="@area.uniqueid">@area.name</option>} </select> </div> </td> </tr> </table> <div class="pull-right"> <button class="btn btn-large btn-primary" type="submit">Save simulation</button> </div> } }

TestController:

 Form<Test> filledForm = Form.form(Test.class).bindFromRequest();

recs = unique_recs_in simply creates a new reference to the list object, to get a completely new copy of a list of lists use copy.deepcopy.

>>> lis = [[1, 2], [3, 4]] >>> a = lis >>> a.append(4) #changes both `a` and `lis` >>> a, lis ([[1, 2], [3, 4], 4], [[1, 2], [3, 4], 4])

Even a shallow copy is not enough for list of lists:

>>> a = lis[:] >>> a[0].append(100) #Inner lists are still same object, just the outer list has changed. >>> a, lis ([[1, 2, 100], [3, 4]], [[1, 2, 100], [3, 4]])

copy.deepcopy returns a completely new copy:

>>> import copy >>> a = copy.deepcopy(lis) >>> lis [[1, 2, 100], [3, 4], 4] >>> a.append(999) >>> a, lis ([[1, 2, 100], [3, 4], 4, 999], [[1, 2, 100], [3, 4], 4]) >>> a[0].append(1000) >>> a, lis ([[1, 2, 100, 1000], [3, 4], 4, 999], [[1, 2, 100], [3, 4], 4])

If the list contains only immutable objects, then only a shallow copy is enough:

recs = unique_recs_in[:]

Int is the Best type for Id column in a table in SQL Server

If the table eventually has too many records we can change to BigInt

We can also create the Id as the Identity and/or PK of the table.

CREATE TABLE [dbo].[TableName]( [TableNameId] [int] IDENTITY(1,1) NOT NULL ) ON [PRIMARY]

Example of Identity & Primary Key

CREATE TABLE [dbo].[TableName3]( [TableName3Id] [int] IDENTITY(1,1) NOT NULL, CONSTRAINT [PK_TableName3] PRIMARY KEY CLUSTERED ( [TableName3Id] ASC ) )

Hope this helps your question helped me.

Logo image is doubled and reduced to smaller size with set pixel width and height. I want the image cleaner and not blurry. Logo still is original size in outlook.

Do I need to wrap this in it's own table to a set pixel width? Do I need to set a certain class to it? How can I clean up this code to work more efficiently?

<td bgcolor="#FFFFFF" width="150" align="center" target="_blank"><a href="http://www...."><img src="http://..t_lgo-300.jpg" width="150px" height="89px" alt="" style="display: block; border: 0; font-family: 'Open Sans', Arial, sans-serif; color: #86898B; font-style: normal; font-size: 18px; line-height:10px; width: 150px; height: 89px;"></a></td>

styles - the logo does not have a class....

The JoinColumn annotation is not mandatory. I am not sure why so many tutorials use this annotation since it only overrides the default behaviour. When they do not like the default generated name a custom naming strategy would be the better choice.

To keep it short:

There is not JoinColumn annotation, because its optional and someone has decided not to use it. Maybe he wants the default behaviour.
TargetEntity is only necessary if the related entity is different than the one in the model. (Maybe another implementation of a class)

9461499 0 Using ORMLite for Android, does allow creation of Table with Certain Column Names

I was just About to create a Sample for Proper Understanding on how the Hello Android for ORMLite works in Android.

 public class SchoolDataBean { // id is generated by the database and set on the object automagically @DatabaseField(generatedId = true) int rollNo; @DatabaseField(index = true) String name; @DatabaseField String gender; @DatabaseField boolean presence; public SchoolDataBean() { //required by ORM :) } public void setRollNo(int rollNo) { this.rollNo = rollNo; } public void setName(String name) { this.name = name; } public void setGender(String gender) { this.gender = gender; } public void setPresence(boolean presence) { this.presence = presence; } }

In the Database Helper when I try Inserting the initial Values and creating the table with

 SchoolDataBean schoolDataSecond = new SchoolDataBean(); schoolDataSecond.setName("Ram"); schoolDataSecond.setGender("F"); schoolDataSecond.setPresence(true); schoolDataSecond.setRollNo(2); dao.create(schoolDataSecond);

I get this exception from the ORMLite Library as

 sqlite returned: error code = 1, msg = duplicate column name: gender java.sql.SQLException: SQL statement failed: CREATE TABLE `schooldata` (`rollNo` INTEGER PRIMARY KEY AUTOINCREMENT , `name` VARCHAR , `gender` VARCHAR , `gender` VARCHAR , `presence` SMALLINT )

thanks everyone.

 The Exception seems to be caused at this line TableUtils.createTable(connectionSource, SchoolDataBean.class);

7982311 0 Why does the Facebook Public Search via API return different results when using an access token and when not?

You can try it out yourself.

Be logged in to Facebook and go here: https://developers.facebook.com/docs/reference/api/

Hit the first link in the "Searching" section, called https://graph.facebook.com/search?q=watermelon&type=post. Be sure that it contains your access token as a parameter. Look at the results.

Now remove the access token from the url, hit enter, and look at the results again. They differ. Why?

As far as I'm concerned, the search method does not make use of any permissions. So why is the result not the same?

17781280 0 php character match and allow special characters

I am trying to make a website which will use registration, login actions.

I am trying it in my localhost. At this stage I've created only database for users and login action.

The problem is I've set my username "viral4ever" in database. Login action is working properly but I can login using "viral4ever", "VIRAL4EVER" and all. I don't want that in my system. I want to check every character in my database to login, if it matches "viral4ever" then it should get me in, not with Viral4ever or vIRAL4ever or VIRAL4EVER and all.

I also want to allow users to use ".", "_","-" in their username. So kindly help me with this.

I am using MySQL database and to login and check users I am using this function...

function user_exists($username){ $username = sanitize($username); return (mysql_result(mysql_query("SELECT `user_id` FROM `users` WHERE `username` = '$username'"), 0) == 1) ? true : false; } function sanitize($data) { return mysql_real_escape_string($data); }

The app or user may change either the default time zone for an application (using +[NSTimeZone setDefaultTimeZone]) or the system time zone (using System Preferences) at any time. +[NSTimeZone localTimeZone] returns a proxy that will always act as if it is the current default time zone for the application, even if that default changes. You could change the default time zone for an application to make it behave as if it were in a different time zone.

+[NSTimeZone systemTimeZone] returns the current system time zone (as set using System Preferences). In most cases, these will be the same (the app's default time zone is set to the system time zone at app startup, I believe).

If you want to know the system's time zone setting, you probably want to use +[NSTimeZone systemTimeZone]. If you just want the correct time zone for your app to work in, you probably want +[NSTimeZone localTimeZone].

This looks to me like more of a SQL question so I will answer it accordingly. If you aren't looking for a SQL-based answer please be more clear in the question. And if you are please amend your tags.

As long as the number of types is fixed and known, the following SQL can form your underlying SQL query (assuming the source is a SQL database):

SELECT a.StaffID, Name, CASE WHEN b.ID IS NOT NULL THEN 1 ELSE 0 END AS Type1, CASE WHEN c.ID IS NOT NULL THEN 1 ELSE 0 END AS Type2, CASE WHEN d.ID IS NOT NULL THEN 1 ELSE 0 END AS Type3 FROM dbo.Staff a LEFT JOIN dbo.StaffType b ON a.StaffID = b.StaffID AND b.TypeID = 1 LEFT JOIN dbo.StaffType c ON a.StaffID = c.StaffID AND c.TypeID = 2 LEFT JOIN dbo.StaffType d ON a.StaffID = d.StaffID AND d.TypeID = 3

In your GridView each checkbox will know its StaffID (from the row) and TypeID (from the column) so simply handle its OnChanged event and call something like:

DECLARE @StaffID INT = 1, @TypeID INT = 1 IF EXISTS (SELECT * FROM dbo.StaffType WHERE StaffID = @StaffID AND TypeID = @TypeID) DELETE FROM dbo.StaffType WHERE StaffID = @StaffID AND TypeID = @TypeID ELSE INSERT INTO dbo.StaffType ( StaffID, TypeID ) VALUES ( @StaffID, @TypeID )

Updated with LINQ version:

var q2 = from staff in staffList from type1 in typesList .Where(t => t.StaffID == staff.StaffID && t.TypeID == 1) .DefaultIfEmpty() from type2 in typesList .Where(t => t.StaffID == staff.StaffID && t.TypeID == 2) .DefaultIfEmpty() from type3 in typesList .Where(t => t.StaffID == staff.StaffID && t.TypeID == 3) .DefaultIfEmpty() select new { StaffID = staff.StaffID, Name = staff.Name, Type1 = (type1 != null), Type2 = (type2 != null), Type3 = (type3 != null) };

double is not an exact type, as you can see by applying the std::numeric_limits typetrait:

#include <limits> static_assert(std::numeric_limits<double>::is_exact == false);

Thus computations involving doubles are only approximate, and there is nothing wrong about what you observe.

There is no problem with your code.

Roughly, Magento is creating an order collection for you and attempting to load all the records. This collection has a rule that only allows it to create one order object for each ID, so when your additional object is loaded an exception is thrown.

The left joins could be the issue, but it's hard to say off the bat. Could you post a little detail on how you are making the API call? An incorrect join can often have this problem.

EDIT:

If you're using the default code, my first guess would be that there are erroneous records in the database, or that this is an upgraded Magento system which had a bad upgrade in the past. Try this on a clean copy of your EE version pointing to the same database. If the same problem occurs, you may need to spelunk in the database looking for the reason for the problematic data load. Since you already have the query, you may want to separate out parts of the query to see if some subquery is returning too much data.

Without CTEs you can do:

Select Z.Department, Z.AvgWage From ( Select Department, Avg(Wage) AvgWage From Employees Group By Department ) As Z Where AvgWage = ( Select Max(Z1.AvgWage) From ( Select Department, Avg(Wage) AvgWage From Employees Group By Department ) Z1 )

With CTEs you could do:

With AvgWages As ( Select Department , Avg(Wage) AvgWage , Rank() Over( Order By Avg(Wage) Desc ) WageRank From Employees Group By Department ) Select Department, AvgWage, WageRank From AvgWages Where WageRank = 1

I know you said there's no dangling extern "C"... But why would that even be an issue given how you are compiling with gcc and not g++??? (Which will, in fact, happily treat smsdk_ext.cpp as a C and NOT C++ file... With all the errors and pain that come from doing so...)

Often you will see such error messages when the wrong include files are tagged extern "C". (Or not properly tagged as the case may be.)

Your error messages also indicate difficulty overloading functions...

platform.h: In function ‘double fsel(double, double, double)’: platform.h:470: error: declaration of C function 'double fsel(double, double, double)' conflicts with platform.h:466: error: previous declaration 'float fsel(float, float, float)'

And problems with system (compiler) files.

In file included from /usr/include/sys/signal.h:104, from /usr/include/signal.h:5, from /usr/include/pthread.h:15, from /cygdrive/... /usr/include/cygwin/signal.h:74: error: expected ‘;’ before ‘*’ token /usr/include/cygwin/signal.h:97: error: ‘uid_t’ does not name a type In file included from /usr/include/signal.h:5, from /usr/include/pthread.h:15, from /cygdrive/... /usr/include/sys/signal.h:163: error: ‘pthread_t’ was not declared in this scope /usr/include/sys/signal.h:163: error: expected primary-expression before ‘int’ /usr/include/sys/signal.h:163: error: initializer expression list treated as compound expression

So either your compiler installation is really munged OR...

Alternatively, another approach is to start with a minimal Hello World program and see if that compiles. Then build up, including what you need to, until you hit a problem. (Or take the existing software and simplify it down until you find the problem area. Start with one "g++" line, copy the file, and pare it down until the problem goes away. Perhaps you have a #define or typedef that conflicts with something in a system file.)

15398954 0 Something wrong either with lParam or with WCHAR[]

First, this function is called many times. It should be noted that wString[] does contain the character constant '\n'.

void D2DResources::PutToLog(WCHAR wString[]) { int strLen=wcslen(wString); int logLen=wcslen(log); if(strLen+logLen>=MaxLogSize) wcsncpy(log, log, logLen-strLen); wcscat (log, wString); int nLines=0; for(int x=0; x<wcslen(log); x++) { if(log[x]=='\n') { nLines++; if(nLines>5) { log[x]='\0'; } } } SendMessage (m_hWnd, WM_PAINT, NULL, (LPARAM)nLines); }

At the end, a WM_PAINT message is sent while nLines should be non-zero since log contains multiples '\n'. My WndProc receives the message and processes it.

case WM_PAINT: { pD2DResources->OnRender((int)lParam); ValidateRect(hWnd, NULL); } break;

After which OnRender is called with a (supposedly) non-zero int as an lParam.

void D2DResources::OnRender(int nLogLines) { D2D1_SIZE_F screenSize = pCurrentScreen->GetSize(); D2D1_SIZE_F rTSize = pRT->GetSize(); pRT->BeginDraw(); pRT->DrawBitmap( pCurrentScreen, D2D1::RectF(0.0f, 0.0f, screenSize.width, screenSize.height) ); pRT->DrawText( log, ARRAYSIZE(log) - 1, pTextFormat, D2D1::RectF(0, rTSize.height - ((nLogLines*textSize)+textSize) , rTSize.width, rTSize.height), pWhiteBrush ); pRT->EndDraw(); }

For some reason, in the OnRender function, nLogLines' value is 0. What is wrong?

41051059 1 SQLITE SUBQUERIES

I have a SQLITE Table that holds information in the following format. The first column is ID, second is ID_1, third is ID_2 and final column is Volume.

ID ID_1 ID_2 Volume 1000 111 0 1000 111 1 1000 111 2 1000 111 3 1000 112 0 1000 112 1 1000 112 2 1000 112 3 1000 113 0

There are 10 or more unique ID values, about 2000 unique ID_1 values and 4 unique values for ID_2.

At the end I want to select volume for selected IDs, selected ID_1 and selected ID_2. Things work well this far. The output format should be - ID, ID_1, Volume

What I am confused about is to get the following data.

I need the following data:

For a given ID and ID_1, if ID_2 = 1, then

Volume = (Volume for ID, ID_1 and ID_2 = 1) - (Volume for ID, ID_1 and ID_2 = 2)- (Volume for ID, ID_1 and ID_2 = 3)

Otherwise print volume like it is.

I am using python to extract this data in a csv file. I am trying to store ID and ID_1 into value1 and value2 and using that in subquery but it doesnt seem to be working.

My code looks like the following:

import os import sqlite3 import shutil import csv import time import datetime from pprint import pprint value1 ="va" value2 ="pa" working_dir = "C:\Path" aimsun_db_filename = os.path.join(working_dir,"File.sqlite") conn = sqlite3.connect(filename) c= conn.cursor() SQL = ''' SELECT TableName.ID '''= value1 +''', TableName.ID_1 '''= value2 +''', CASE WHEN ID_2 = 1 THEN (SELECT TableName.volume FROM TableName WHERE ID_2 = 2 and TableName.oid = '''+value1+''' AND TableName.did = '''+value2+''' ) WHEN ID_2 = 2 THEN TableName.volume WHEN ID_2 = 3 THEN TableName.volume ELSE "Other" END, FROM TableName WHERE AND NOT sid = 0 AND NOT ent = 0 ''' with conn: c = conn.cursor() c.execute(SQL) while True: row = c.fetchone() if row ==None: break

Your struct here:

struct weighted_pointer{ mutable int weight; unique_ptr<likeatree> ptr; };

contains a std::unique_ptr. A std::unique_ptr cannot be copied, so your entire weighted_pointer cannot be copied as well.

There are three places in your code where you attempt to copy it, which causes the errors you see:

bool operator()(const weighted_pointer lhs, const weighted_pointer rhs) {

Must be:

bool operator()(weighted_pointer const& lhs, weighted_pointer const& rhs) {

stdSet.insert(tmp);

This could theoretically be fixed by:

stdSet.insert(std::move(tmp));

However, you then cannot use tmp anymore, which you do, not only in the same loop but also in the loop below. So you must find a different solution altogether. Perhaps use emplace. Or restructure your code entirely.

auto it = find_if(stdSet.begin(),stdSet.end(),[&](weighted_pointer temp){ return temp.ptr.get() == treeVector[i]; });

Must be:

auto it = find_if(stdSet.begin(),stdSet.end(),[&](weighted_pointer const& temp){ return temp.ptr.get() == treeVector[i]; });

For VC++ 2013, the std::move fix will not suffice. You will have to add an explicit move constructor to your struct:

struct weighted_pointer{ mutable int weight; unique_ptr<likeatree> ptr; weighted_pointer() = default; weighted_pointer(weighted_pointer&& src) : weight(std::move(src.weight)), ptr(std::move(src.ptr)) { } };

VC++ 2015 fixes this problem. More information: Default Move Constructor in Visual Studio 2013 (Update 3)

Try out this framework : https://github.com/AdrianFlorian/AFImageViewer to present images in a scroll view using a page controll to indicate the current page.

I have't added documentation yet, but you can see examples if you clone the project.

You can easily: - download images from the internet in a separate thread by only giving an array of urls (image urls) - give it an array of UIImage objects - implement a delegate and manage the image for each page yourself

30541294 0 Computation with Floating Point Numbers: When to Round?

I'm performing some computations in C with floating point numbers. I'm specifically dealing with the case where I get the lowest possible single precision value for the exponent.

Say my exponent is -126 and I have to decrement it. In this case, I can't go any lower, so I need to right shift my mantissa once. I know I'm supposed to get the exact answer for a calculation and then round (to whatever place is specified).

I'm thinking of doing (let M be the mantissa):

M >>= 1; //round mantissa

since I'm shifting the mantissa to the right and there was an implied 1 to the left of the floating point, do I need to modify M after shifting with something like:
```
M |= (1 << 23) 
```
to ensure I have a 1 in the most significant bit?
It seems weird to round after losing a bit of information but is this standard / accepted practice? Or should I calculate the full result by using more bits and then rounding?

You might have have to set the temporary download path so that it writes it to disk while downloading the document. As is, it could be keeping the whole thing in memory and crashing when the memory footprint has become unacceptable to the system. The documentation isn't entirely clear on this.

When downloading data to a file using downloadDestinationPath, data will be saved in a temporary file while the request is in progress. This file’s path is stored in temporaryFileDownloadPath.

I can't seem to find out what happens if temporaryFileDownloadPath is nil.

when a link was clicked using php

I would like to ask some help on this thing. I created a site that has a lot of div and what I want is that when a link is clicked only one div will be displayed without reloading the whole page.

Sample code:

<ul> <li><a href="">Div 1</a></li> <li><a href="">Div 2</a></li> <li><a href="">Div 3</a></li> </ul> <div id="content1"> <p>This is content 1</p> </div> <div id="content2"> <p>This is content 2</p> </div> <div id="content3"> <p>This is content 13</p> </div>

Is it possible if I'll just use php? And please help me on how I will do it.

1450629 0 how to connect and sends data betweens many computers using Java networking

I am beginner of learning Java Networking.I want to connect 3 or more computers. One for server and others(eg A and B )for clients .But I want to connect

A to Server and vise versa
B to Server and vise versa
A to B and vise versa

First I want to send message from either A or B to server and server sends stored data to sender (eg A) and sender (A) will connect to B. Then A and B will confirm message and A and B will send data one to another. But this occasion can occurs from A and B concurrently.

But I just learned simple code for connection of one server and one client using Server socket and socket. Will all 3 computers require to act for both server and client? Is there other ways to connect between clients. I don't know how to consider to solve data conflict between computers. I also want to satisfy if new clients are added. If anyone know to solve above problem including data conflicts, pls help me with simple sample code for both server and clients.

Thanks !!

2678296 0 Padding to the left and right of a floated image, in IE only

Generally I seem to be able to fix IE problems nowadays.. but this one realy has me stuck!

Take a look at the screenshot below to see the problem or visit the url to see the problem.

http://homedynamics.com/sawgrass/floorplan.php

alt text

I have made sure the ul li and img's are all cleared (padding:0; margin:0; border:0;) and still there is padding added to the left and right of the images. I also did "display: block" on images with no luck.

Can anyone point me in the right direction? Thanks!!

I've been looking at your issue and haven't been able to get it working either. I tried using the XJC schema compiler and it is also having problems with schema conflicts, and EclipseLink depends on XJC for Dynamic JAXB context creation.

First off, when I ran your test case in Eclipse I got a slightly different error:

com.sun.istack.SAXParseException2: Property "Title" is already defined. Use &lt;jaxb:property> to resolve this conflict.

But I see that in your bindings file you're already using jaxb:property for title (lowercase), and I couldn't find any Title (uppercase) in any of the related XSDs.

Second, when I ran XJC I got:

C:\...\src\omar>xjc example-feature.xsd -b xlink-bindings.xjb parsing a schema... compiling a schema... [ERROR] Two declarations cause a collision in the ObjectFactory class. line 28 of http://schemas.opengis.net/gml/2.1.2/feature.xsd [ERROR] (Related to above error) This is the other declaration. line 29 of http://schemas.opengis.net/gml/2.1.2/feature.xsd Failed to produce code.

But this is also strange because line 29 of feature.xsd is:

<element name="geometryProperty" type="gml:GeometryAssociationType"/>

But I can't find any conflict with geometryProperty.

Hopefully this is enough information for you get a bindings file in order that will get XJC working. At that point you should be able to bootstrap a DynamicJAXBContext. The xjc executable is located in your JAVA_HOME\bin directory.

Note change event fires after the input loses focus. You may want to use input event instead.

To convert the string to numbers, you can use the unary operator + instead of Number.

To default to 0 when some expression is falsy, you can use expr || 0.

var field1 = document.getElementById('field1'), field2 = document.getElementById('field2'), total = document.getElementById('total'); field1.oninput = field2.oninput = function updateTotalCosts() { total.value = (+field1.value || 0) + (+field2.value || 0); };

<input id="field1" /> + <input id="field2" /> = <input id="total" />

Or, using jQuery,

var $field1 = $('#field1'), $field2 = $('#field2'), $total = $('#total'); $field1.add($field2).on('input change', function updateTotalCosts() { $total.val((+$field1.val() || 0) + (+$field2.val() || 0)); });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <input id="field1" /> + <input id="field2" /> = <input id="total" />

This would print a JSON with all of the properties (public, private and protected) of class foo:

$reflection = new ReflectionClass('foo'); $properties = $reflection->getdefaultProperties(); echo json_encode($properties);

I poked at your program for a while without having much to show for it. Perhaps I realized too late that it was not supposed to reproduce the problem :( I can only provide some possibly helpful hints to get you to look under the right kind of rock.

yet it was solved via a hack that doesn't work for me

These programmers made a simple mistake, they forgot to call CoInitialize/Ex(). A very common oversight. Using the /clr build option works around that mistake because it is now the CLR that calls it. You can easily repro this mishap, just comment out the CoInitialize() call. Unfortunately it works for a while without any loud errors being produced, but you do get 0 for certain accobjects. You'll notice your program no longer finds the tabs.

Not so sure I can cleanly explain this, certain COM-style object models don't actually use the COM infrastructure. DirectX is the best example, we can add UIAutomation to that list. I assume it will silently fail like this when the client app's component is COM-based. Unclear if it is, DirectUIHWnd is quite undocumented.

So stop looking for that as a workaround, you did not forget to call CoInitialize() and it will be taken care of by IE before it activates your extension.

If you run IE with administrator privileges, it works properly.

That's a better rock. Many programmers run VS elevated all the time, the roles might be reversed in the case of UIA. Do keep in mind that your extension runs in a sandbox inside IE. No real idea how elevating IE affects this. One thing you cannot do from code running in the low-integrity sandbox is poke at UI components owned by a code that runs in a higher integrity mode. Google "disable IE enhanced protected mode" and follow the guideline to see what effect that has on your addin.

This problem is not specific to Entity Framework (although EF certainly also has other limitations around UNIQUE constraints). This is common with any similar server-client model. Since the uniqueness will be enforced by the database server at the time of the request, there is no fool-proof way to know in advance if the constraint will be violated, until you attempt the insert.

That said, checking for uniqueness in advance should be a very cheap operation (on SQL Server, a UNIQUE constraint will also give you an index on that column), so depending on how often you expect the application to be attempting duplicate insertion, this should cover the large majority of your cases. But if the duplicate insert attempts would be quite rare to begin with, you can avoid making the extra round-trip per insert and just handle the exception when it happens.

Handling the exception doesn't need to be very complicated, especially if there is a way for the end user to modify the data and attempt a retry. In the case where, as you said, you're queuing-up several inserts in a single transaction, you may need to check the exception (or inner exception) for specific constraint names, so that you know which entity object is a duplicate. (Again, EF doesn't really support handling UNIQUE constraint exceptions directly, so this is probably the part that is causing you the most pain right now.)

Note: I would not recommend re-working the insert as a stored procedure just to circumvent the rare chance that duplicate entries get attempted concurrently. You're better off making sure your application handles this (and other SQL exceptions, of which there may be many) as gracefully as possible. However, if you are finding that in your case there is really no other way, a sproc may be the easiest approach for now. Just keep in mind that it's probably foregoing more maintainable code in order to solve a very rare edge case.

You can add functions to Studio by putting PHP files with stub function descriptions into special directory. Find this directory in filesystem in a following way: write something like gmdate(), select the name and press F3. You will be taken to one of the prototype files. Note the directory where this file resides (shown on the top and if you hover over the tab). Now you need to create stubs for functions you are missing just like the one you're looking at. You can put them into any file, generally, but I suggest putting them into separate file - like geoip.php - and put this file into that directory. You may also want to do right-click/Show In/PHP Explorer and browse other prototype files if you need examples of how to do it right.

It defines whether to fade out scrollbars when they are not in use. Must be a boolean value, either "true" or "false". Source.

Using code the View.setScrollbarFadingEnabled(boolean) is what you can use.

I think StringTokenizer based solution will be the fastest

public static int[] splitDateTime(String dateTime) { int[] intParts = new int[5]; StringTokenizer t = new StringTokenizer(dateTime, "/ :"); for (int i = 0; t.hasMoreTokens(); i++) { intParts[i] = Integer.parseInt(t.nextToken()); } return intParts; } public static void main(final String[] args) throws IOException { System.out.println(Arrays.toString(splitDateTime("01/03/2013 09:00"))); }

From the top of my mind:

void * const var; // The pointer is constant and var can change const void * var; // The pointer can change but not var

so I would think that your syntax

const void * const *ptr;

means that ptr is a pointer to a pointer. So ptr would point to an address and that address cannot change (the first const). Also the address that ptr is located cannot change (the second const). But I am not totally sure of this.

Your getting that error because your building against the simulator in Xcode.

Switch to your device and this goes away.

If you didn't intent to run against the bundle re-comment this in AppDelegate.m

jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

and turn your local dev server back on:

jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];

29518495 0 pyinstaller single exe of program which uses google api client lib

I have a python program which I've successfully packaged up as a single exe using pyinstaller in the past. Recently I added new features which make use of the google api python client ( https://developers.google.com/api-client-library/python/ ). I've attempted to make a new single exe package of the new version and it fails to run.

I enable debugging and the console and initially the issue was that it hadn't picked up the oauth lib. I fixed that by adding the following to my spec file:

hiddenimports=['googleapiclient', 'apiclient']

When I build I can see this:

53092 INFO: Hidden import 'googleapiclient' has been found otherwise 53093 INFO: Hidden import 'apiclient' has been found otherwise

However, now when I run the rebuilt exe I get the following error before it exits:

pkg_resources.DistributionNotFound: google-api-python-client

I can't see any reference to that and I'm not sure how to force it to be packaged up with the exe.

I figure I can't be the only person to have ever wanted to package up a python program that makes use of the google api, but I failed to find any help during a lot of time with my friend google...

Any tips?

You could look at the trace module in the standard library, which

allows you to trace program execution, generate annotated statement coverage listings, print caller/callee relationships and list functions executed during a program run. It can be used in another program or from the command line.

You can also log to disk:

import sys import trace # create a Trace object, telling it what to ignore, and whether to # do tracing or line-counting or both. tracer = trace.Trace( ignoredirs=[sys.prefix, sys.exec_prefix], trace=0, count=1) # run the new command using the given tracer tracer.run('main()') # make a report, placing output in /tmp r = tracer.results() r.write_results(show_missing=True, coverdir="/tmp")

Check that your "client" table allows ID value as NULL. I believe that's the problem because if you setup your table correctly that would be your primary key which should not be NULL.

It's a conflict of slugs.

You will get conflicts if you have the same slug for a page and a CPT that uses that too. So for you, your CPT is using 'product', and your page is too. That's conflicting and causing the 404.

Rename your page Product Info page' slug to product-info.

For safety purposes flush your permalink cache by setting them to Default, saving, then saving them as what you had previously.

14244807 0 Line feed is being removed from echo when called in double-quotes

I'm trying to populate a shell variable called $recipient which should contain a value followed by a new-line.

$ set -x # force bash to show commands as it executes them

I start by populating $user, which is the value that I want to be followed by the newline.

$ user=user@xxx.com + user=user@xxx.com

I then call echo $user inside a double-quoted command substitution. The echo statement should create a newline after $user, and the double-quotes should preserve the newline.

$ recipient="$(echo $user)" ++ echo user@xxx.com + recipient=user@xxx.com

However when I print $recipient, I can see that the newline has been discarded.

$ echo "'recipient'" + echo ''\''recipient'\''' 'recipient'

I've found the same behaviour under bash versions 4.1.5 and 3.1.17, and also replicated the issue under dash.

I tried using "printf" rather than echo; this didn't change anything.

Is this expected behaviour?

Try "cleaning" the solution, i.e. delete (rename) all temporary files like *.ncb, *.suo etc that have been created by Visual Studio. One of these files might have got corrupted (Your problem sounds like the IntelliSense database is broken).

If you still need to write code under -(void)methodA do

-(void)methodA { if(!isKeyBoarHidden){ [textField resignFirstResponder]; } else{ //code here } } - (void)keyboardHidden:(NSNotification *)notification { isKeyBoarHidden = YES; [self methodA]; }

sometime it may be helpful if we have some local variables inside methodA and we dont need to make variables global.

As a starting point I'd look at the WinSock API. You may find a way of pulling traffic information on a per process basis. If you want to see total network usage, I'd use the Performance Monitoring tools. I found this example from a web search:

private static void ShowNetworkTraffic() { PerformanceCounterCategory performanceCounterCategory = new PerformanceCounterCategory("Network Interface"); string instance = performanceCounterCategory.GetInstanceNames()[0]; // 1st NIC ! PerformanceCounter performanceCounterSent = new PerformanceCounter("Network Interface", "Bytes Sent/sec", instance); PerformanceCounter performanceCounterReceived = new PerformanceCounter("Network Interface", "Bytes Received/sec", instance); for (int i = 0; i < 10; i++) { Console.WriteLine("bytes sent: {0}k\tbytes received: {1}k", performanceCounterSent.NextValue() / 1024, performanceCounterReceived.NextValue() / 1024); Thread.Sleep(500); } }

16382578 0 Stopping UIScrollView at specific place while scrolling with pagingEnabled

I have the following code to create a scroll view with additional area at the beginning and the end of the images (50 points).

UIScrollView* scroll = [[UIScrollView alloc] initWithFrame: CGRectMake(0,0,200,100)]; scroll.contentSize = CGSizeMake(400,100); UIImageView* img1 = [[UIImageView alloc] initWithFrame: CGRectMake(50,0,100,100); UIImageView* img2 = [[UIImageView alloc] initWithFrame: CGRectMake(150,0,100,100); UIImageView* img3 = [[UIImageView alloc] initWithFrame: CGRectMake(250,0,100,100); //Adding images to ImageViews scroll.pagingEnabled = YES; [scroll addSubView:img1]; [scroll addSubView:img2]; [scroll addSubView:img3];

The first time I see the view, I will see the additional area on the left (0-50), then the first image (50-150) and then half of the second image (150-200). When I swipe left, I want to see half of the first image on the right, the second image at the center, and half of the third image on the right.

When I swipe left again, I want to see the third image at center, with half of the second image on the left, and the additional area on the right.

Can it be possible?

I guess you may be seeing a NPE, as you may be violating the paragraph you were citing:

String custData = custFacade.find(customerId).toString();

The find seems to implicitly querying for the object (as you describe), which may not be fully synced to the database and thus not yet accessible.

#!/bin/bash sudo nohup python dejavu/sniffer.py $1 $2 $3 > /var/log/apache2/sniffer.log 2>&1 & echo $!

for some reason the following does nothing however, it does return a PID.

The shell script works fine on it's own. exec($cmd) does nothing as well.

16819118 0 AnythingSlider in a "random access" mode

I would like to use AnythingSlider to implement a multiple-panel login dialog. One requirement is that I will want to navigate to different panels in a random order, and I want the transitions to only show the source and destination panels, none of the intervening ones.

For example:

Panel 1 is the primary login step (username / password)
Panel 2 is a secondary login step (security question)
Panel 3 is a password recovery panel
Panel 4 is something else again

Navigation between panels is controlled by buttons and logic outside of the slider element.

If the user starts at Panel 1, and wants to try Password Recovery, I would like to slide in Panel 3 from the right without seeing panel 2 on the way by.

Is there a way to accomplish this with AnythingSlider?

33460100 0 What's wrong with my CodeEval challenge solution?

I'm new to coding, and after doing some online tutorials I decided to do a few challenges on CodeEval, and just got the balls to try a hard one. I submitted my solution, and it says it's partially solved, and I just can't figure out what I'm doing wrong. I'm not sure if these challenges are something that I'm supposed to do 100% on my own, in which case I won't submit a solution that includes any input from people on here. I just want to know what I should do better.

Here is the link to the challenge: https://www.codeeval.com/open_challenges/126/

And here is my code (JavaScript):

function compareSegments(segment1, segment2) { var totalMisMatches = 0; for (var i = 0; i < segment1.length; i++) { if (segment1[i] != segment2[i]) { totalMisMatches++; } } return totalMisMatches; } function makeInnerSegment(array, index, length) { var newArray = []; for (var j = 0; j < length; j++) { newArray.push(array[index + j]); } return newArray; } function compare(a, b) { for (var i = 0; i < a.length; i++) { if (a[i] < b[i]) { return -1; } if (a[i] > b[i]) { return 1; } } return 0; } function makeArrayOfPossibleSegments(array, segment, maxMismatches) { var newArray = []; for (var i = 0; i <= array.length - segment.length; i++) { var innerSegment = makeInnerSegment(array, i, segment.length); var mismatches = compareSegments(segment, innerSegment); if (!(mismatches > maxMismatches)) { innerSegment.unshift(mismatches); newArray.push(innerSegment); } } return newArray.sort(compare); } var fs = require("fs"); fs.readFileSync(process.argv[2]).toString().split('\n').forEach(function (line) { if (line !== "") { var output = ""; var splitArray = line.split(" "); var DNASegment = splitArray[0].split(""); var maxMisMatches = parseInt(splitArray[1]); var DNAString = splitArray[2].split(""); var possibleSegments = makeArrayOfPossibleSegments(DNAString, DNASegment, maxMisMatches); if (possibleSegments.length === 0) { output = "No match"; } else { for (var i = 0; i < possibleSegments.length; i++) { for (var j = 1; j < possibleSegments[i].length; j++) { output += possibleSegments[i][j]; } output += " "; } output = output.substring(0, output.length - 1) } console.log(output); } });

You are close.

What you are doing:

you set the Tag of TreeView to its own DataContext. This is unnecessary.
you try to get Tag.MyText from your ContextMenu.PlacementTarget - which is TextBlock. The TextBlock has no Tag set.

What you should do:

set the Tag of the TextBlock to DataContext of the Window (Window is TextBlock ancestor and you should look it up via RelativeSource Mode=FindAncestor).
the second part is OK - you have TextBlock.Tag set in the first step.

2694406 0 How to find what element mouse is over in Prototype

I have a situation where an element is shown using ajax. I have attached mouseenter and mouseleave events to it to show a menu connected to the element using prototype. This works fine, but the problem I am having is that if a user has his/her mouse in the place where the element is shown before it is shown, the mouseenter does not get triggered and the attached menu does not get shown. I already have an afterFinish function that is called after a SlideDown effect, so I was thinking I could put another function in there to check if the users mouse is over the element or not. How would I go about checking what element the users mouse is over in prototype?

consider each part of the order by as a different column... Apply a case to each component. Get the first part first... then the second part. If it doesn't apply to the second part, just have it always the same value... something like...

This is happening because you're calling message+= on a null string, so you're adding currentLine to null.

Simplest fix would be to set massage to "" when you initialise it:

String message = ""; //Rest of code...

If what you're talking about is the space in between each box, the class "box" is inline-block, so the line-breaks in the markup are interpreted as implied spaces. Place all the inline-block markup on a single line <div></div><div></div>... and the "space" between will collapse.

I have adapted the solution from http://craftycodeblog.com/2010/05/15/asp-net-mvc-render-partial-view-to-string/ to your case.

Change your code from project B to this:

public ActionResult Index() { var form = pa.Index(); // <-- This is the controller from controller A using (var sw = new StringWriter()) { // Find the actual partial view. var viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, form.ViewName); // Build a view context. var viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw); // Render the view. viewResult.View.Render(viewContext, sw); // Get the string rendered. ViewBag.CMSForm = sw.GetStringBuilder().ToString(); } return View(); }

Without knowing the contents of 'BBnormalLinks.txt' or the final value of $rand_link, it is difficult to say precisely what is going wrong.

Your usage of file() and mt_rand() appear to be correct, though you aren't doing anything to ensure that you are getting a valid URL.

This is purely conjecture, but I suspect that you don't have PHP properly configured to display errors. If the file fails to load, $links will have a null value going into your penultimate line. You will then try to access element 0 of a null array and receive an empty value. This will result in header('refresh:2;url=') and your page will simply refresh itself every 2 seconds.

12592429 0 Custom font in Navigation Bar Truncating uses semicolon not ellipses

I am trying to customize the font on my Navigation Bar. Everything is fine except for some reason, when the title is too long for the Navigation Bar, it gives me a semicolon instead of ellipses (...)

How do I get the ... to show that the title is cut off?

 UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 20, 240, 24)]; label.backgroundColor = [UIColor clearColor]; label.font = [UIFont fontWithName:@"My Font" size:20.0]; label.numberOfLines = 1; label.lineBreakMode = NSLineBreakByTruncatingTail; label.textAlignment = UITextAlignmentCenter; label.textColor =[UIColor whiteColor]; label.text=@"Some Really Long Title Name That's Normally Dynamic"; self.navigationItem.titleView = label;

So I want the Navigation Bar to say "Some Really Long Titl..." However it keeps saying "Some Really Long Title ;"

Thanks!

You could use CountDownLatch

In your main method, you could define how many threads you would have, inject it within each of your threads and wait for their completion. Once a thread completes, its would call countdown api and once all your thread completes, your main method can continue further.

Because .validation-alert is not the next sibling of .validation-control-is-not-empty, they are the children of same tr, so you can find the tr parent of this and then find the .validation-alert element within it.

$('.validation-control-is-not-empty').focusout(function () { if ($(this).val() === '') { $(this).closest('tr').find('.validation-alert').show(); } else { $(this).closest('tr').find('.validation-alert').hide(); } });

You can shorten it using .toggle() like

$('.validation-control-is-not-empty').focusout(function () { $(this).closest('tr').find('.validation-alert').toggle($(this).val() === ''); });

Demo: Fiddle

My 2 cents:

We a have a Flex application and our login screen is part of the Flex application. We don't use SSL but you may define a secure channel if you need it (but you don't);
We created our own instance of the adapter class on the server (that extends the one that comes with BlazeDS). The idea is that this class would check if the session for which that request belongs to has an authenticated user or not. In the Flex methods/ classes (on the Java side), we used annotations to inform the adapter class about requirements that must be satisfied in order for that method to be called - we call these annotations "FlexService" (for the class) and "FlexMethod" (for a method);
- The main reason behind this is to avoid a method from being called if the user has not been authenticated before, and we want more granular control than just "block everybody". We have licensing requirements and this library is also responsible for checking if the user has a license and if that license still valid for each request.
Remember to hash your password before saving it to the database, and compare the hash only. You could hash it one time in the Flex client (so the open password is never sent to the server), and hash the hashed value again before saving it to the database (so that if someone obtain your database hashed passwords, he still cannot hack into your system because he won't have the original hashed value that was sent from the Flex client).

I am pretty sure I will get some downvotes if BlazeDS implements all of the above, but I didn't like what I found that was native to it, and I thought that using annotations was a good solution, especially because we were using annotations anyway to mark the methods that were BlazeDS methods (so IntelliJ would stop bothering us about methods that are not called anywhere).

You should build an url get parameter string:

 <script> $(function() { var data = {kid:[]}; // we put here all checkbox value $("input[type=checkbox][checked]").each(function() { //iterate over all checked checkboxes data.kid.push($(this).attr('id')); //push the id of checkbox to data.kid array }); $("#kontakte_bezButton1_{kontakte_bez:rowNumber}").colorbox({ href:"testpage1.php?" + $.param(data), //create $_GET parameter string iframe:true, innerWidth:850, innerHeight:400, opacity:0.1, overlayClose:false }); }); </script>

The $.param function (http://api.jquery.com/jQuery.param/) generates get parameter string from an object. in this example the result like this:

 kid[]=1&kid[]=4&.... (in urlencoded format: kid%5B%5D=1&kid%5B%5D=4 )

Let's see if simplifying the code a bit can give a clearer picture:

if answer == "yes" return true elsif answer == "no" return false end puts "something"

is the most relevant part here. With the explicit return, the code exits from the method and never reaches the puts. The return value is therefore true or false.

Without the explicit return:

if answer == "yes" true elsif answer == "no" false end puts "something"

The true and false statements merely exit the if-else code and executes the puts, the return value of which is nil.

It sounds like what you're after is to make the fit closer to linear in-between, I think you can force that by interpolating the midpoint as a real point:

dat2 = data.frame(x = union(dat$x,dat$x - c(0,diff(dat$x)/2)), y = interp1(dat$x,dat$y,xi = union(dat$x,dat$x - c(0,diff(dat$x)/2))))

(interp1 may be unnecessary here, union(dat$y,dat$y - c(0,diff(dat$y)/2)) should do the same, but the code above works.)

EDIT: Note, in order for diff to work, you need your data to be properly ordered first

this creates a new data.frame with points in between the previous ones, if you now spline it, you are weighting a more linear fit

EDIT2: You could also use smoothing splines with weights this way, and set the weights of the points in between lower than the weights of the primary points:

mod <- splinefun(dat$x, dat$y,method = 'monoH.FC') mod2 <- data.frame(x = seq(0.333, 5, by = 0.1), y = mod(seq(0.333, 5, by = 0.1))) # A set of weights, where each point in-between is weighted half as much dat2$w <- rep(c(0.5,1),ceiling(length(dat2$x)/2))[-1] # Smoothing Spline modelspline <- smooth.spline(dat2$x, dat2$y,dat2$w) # Plot points xplot <- seq(min(dat2$x),max(dat2$x),by = 0.1) # And Plot comparison ggplot() + geom_point(data = dat, aes(x = x, y = y)) + geom_line(data = mod2, aes(x = x, y = y)) + geom_line(data = data.frame(predict(modelspline,xplot)), aes(x = x, y = y),color = 'red')

Your problem can be solved by following these steps

Step 1:
Add these two packages to your project (jackcess-encrypt.jar, bcprov-jdk15on-152.jar)

You can download the two packages from the following links:

Jackcess Encrypt
Bouncy Castle

Step 2:
You have to add this class to your project folder

import java.io.File; import java.io.IOException; import net.ucanaccess.jdbc.JackcessOpenerInterface; import com.healthmarketscience.jackcess.CryptCodecProvider; import com.healthmarketscience.jackcess.Database; import com.healthmarketscience.jackcess.DatabaseBuilder; public class CryptCodecOpener implements JackcessOpenerInterface { @Override public Database open(File fl,String pwd) throws IOException { DatabaseBuilder dbd =new DatabaseBuilder(fl); dbd.setAutoSync(false); dbd.setCodecProvider(new CryptCodecProvider(pwd)); dbd.setReadOnly(false); return dbd.open(); } //Notice that the parameter setting autosync =true is recommended with UCanAccess for performance reasons. //UCanAccess flushes the updates to disk at transaction end. //For more details about autosync parameter (and related tradeoff), see the Jackcess documentation. }

like this

step 3:
use the following connection code

public void connectToDB(){ try { conn = DriverManager.getConnection("jdbc:ucanaccess://words.accdb;jackcessOpener=CryptCodecOpener", "user", "pass"); } catch (SQLException ex) { ex.printStackTrace(); } }

be careful
-change words.accdb to the name of your Access database
-the "user" can be empty or username of your computer or something else
-the "pass" must be the password of your Access file.

9471576 0 Extract first word in a SQLite3 database

I have a SQLITE3 database wherein I have stored various columns. One column (cmd) in particular contains the full command line and associated parameters. Is there a way to extract just the first word in this column (just before the first space)? I am not interested in seeing the various parameters used, but do want to see the command issued.

Here's an example:

select cmd from log2 limit 3;

 user-sync //depot/PATH/interface.h user-info user-changes -s submitted //depot/PATH/build/...@2011/12/06:18:31:10,@2012/01/18:00:05:55

From the result above, I'd like to use an inline SQL function (if available in SQLITE3) to parse on the first instance of space, and perhaps use a left function call (I know this is not available in SQLITE3) to return just the "user-sync" string. Same for "user-info" and "user-changes".

Any ideas?

Thanks.

You could also use the Files.move utility from Google Guava libraries to rename a file. Its easier than writing your own method.

Moves the file from one path to another. This method can rename a file or move it to a different directory, like the Unix mv command.

I would add a ng-model on your select and then add a watch in your directive. Pass your variable into the directive and output your desired result. Pseudo code:

<select ng-model="myList" class="ng-scope ng-pristine ng-invalid ng-invalid-required"> <option value="" selected="selected" class="">Seleccione un estado</option> </select> <span state selectedItem="myList"></span>

and your directive might look like:

 directive('state', ['$http', function($http){ return { restrict: 'A', scope: { myList: '=myList' }, link: function(scope, element, attrs) { scope.$watch('myList', function (newValue, oldValue) { console.log(changed); } } } }])

Yes everything you've read is correct. Interlocked.Increment is designed so that normal reads will not be false while making the changes to the field. Reading a field is not dangerous, writing a field is.

OK, so now I want to debug into the issue, and I can step down through the code I have written until I reach an object called SEIStub.class For this object, Eclipse is reporting "The source attachment does not include the source for file SEIStub.class"

If I select "Change Attached Source", then a box pops up which correctly identifies the location of src.zip within the correct JDK version. So nothing to change there ...

I have gone into the src.zip manually, and indeed there is no com.sun.internal folder.

One confusing aspect is that when I run my test in a development environment, everything works. When I run my test in a QA environment, I get the stack trace listed out above.

What is most confusing of all, is that although I can put a break point into com.sun.org.apache.xerces.internal.impl.XMLEntityManager, and I can reach that break point after passing through the SEIStub object, I am unable to view any of the variables within that program, and they do not even show up as valid variables when I look in the Eclipse Variables tab.

I am using JDK 1.6.0_25

Hmmm ... very confused and running out of hair to pull out !

Can anyone help me to get my debug operating on this class ?

Many Thanks, Mark

UPDATE: I have also tried downloading the http://openjdk.java.net/projects/jdk6/ and this set of source also seems to be missing all of the com.sun.internal objects.

UPDATE: I am using Eclipse Helios, and a colleague has repeated the same issue using Juno.

Not with the default Route class, but you can make your own route class by deriving from RouteBase. You basically end up having to do all the work yourself of parsing the URL, but you can use the source from Route to help you get started.

14975130 0 iOS crash logs printed to console

My problem appeared when iOS 6 was introduced, but now seems to affect 5.1.1 too.

When the app crashes, the log is printed to the 'Console' and no 'Device Logs' is saved. This is frustrating in so many ways:

console view is too short and all I can see is the log's tail,
copy/paste doesn't work, save to file... produces garbage, it is unusable,
there is no way to preserve logs, symbolicate it, or do anything.

It may be worth mentioning, that we work with accessories and have no way to connect debugger at the same time.

An idea how to fix this would save my day, but any decent workaround will be good too.

Thank you

EDIT: 'Console' and 'Device Logs' are the ones I get in the Organizer.

ElementAt() has to iterate from the beginning of the collection every time it's called. That's why it's so inefficient.

I would suggest another approach - save results generated after last save into a list, and save those results into file from there, not from HastSet itself:

latest list:

var latest = new List<string>();

Adding elements:

if(storage.Add(newElement)) { latest.Add(newElement); }

Saving latest to file:

foreach(var item in latest) { sb.AppendLine(item); } latest.Clear();

2253950 0 Unit Testing Private Method in Resource Managing Class (C++)

I previously asked this question under another name but deleted it because I didn't explain it very well.

Let's say I have a class which manages a file. Let's say that this class treats the file as having a specific file format, and contains methods to perform operations on this file:

class Foo { std::wstring fileName_; public: Foo(const std::wstring& fileName) : fileName_(fileName) { //Construct a Foo here. }; int getChecksum() { //Open the file and read some part of it //Long method to figure out what checksum it is. //Return the checksum. } };

Let's say I'd like to be able to unit test the part of this class that calculates the checksum. Unit testing the parts of the class that load in the file and such is impractical, because to test every part of the getChecksum() method I might need to construct 40 or 50 files!

Now lets say I'd like to reuse the checksum method elsewhere in the class. I extract the method so that it now looks like this:

class Foo { std::wstring fileName_; static int calculateChecksum(const std::vector<unsigned char> &fileBytes) { //Long method to figure out what checksum it is. } public: Foo(const std::wstring& fileName) : fileName_(fileName) { //Construct a Foo here. }; int getChecksum() { //Open the file and read some part of it return calculateChecksum( something ); } void modifyThisFileSomehow() { //Perform modification int newChecksum = calculateChecksum( something ); //Apply the newChecksum to the file } };

Now I'd like to unit test the calculateChecksum() method because it's easy to test and complicated, and I don't care about unit testing getChecksum() because it's simple and very difficult to test. But I can't test calculateChecksum() directly because it is private.

Does anyone know of a solution to this problem?

Are you trying to find the phrase _camera in the current selection? If so just use find and replace (ctrl + F) on the whole java file rather than Find in files and limiting the scope to the selection.

Use the alternative <xsl:for-each> notation to loop over a set of integers:

<xsl:for-each select="1 to 5"> ... '.' will be an integer from 1 to 5 here </xsl:for-each>

To create the filename from this, use

... fs:exists(fs:new(concat('/images/',$imageproductid,'_00', ., '.jpg')

and to create a properly named new element, use <xsl:element>:

<xsl:element name="{concat('IMAGE', .)}"> .. <IMAGEx> contents .. </xsl:element>

You need the notation {..} here because name must be a valid QName (W3C, "11.2 Creating Element Nodes Using xsl:element"), which I take as "the literal text must be a valid possible element name".

Putting that together, you end up with this concise code:

<xsl:template match="product"> <xsl:apply-templates /> <xsl:variable name="imageproductid" select="code" /> <xsl:for-each select="1 to 5"> <xsl:variable name="filename" select="concat('/images/',$imageproductid,'_00', ., '.jpg')" /> <xsl:if test="fs:exists(fs:new($filename))"> <xsl:element name="{concat('IMAGE', .)}"> <xsl:value-of select="$filename" /> </xsl:element> </xsl:if> </xsl:for-each> </xsl:template>

It depends how much complexity is already in your GUI. If you have a hundred dialogs/controls then rewriting it in native C++ might be the wrong answer. In this case, making your GUI into a library makes more sense.

However, its probably a better option to keep your GUI as a process and build a proxy library in native C++ that passes the ICE calls onto your server. (so C++/CLI exe calls a function in a new C++ library that makes a ICE call to the server and vice-versa).

If your GUI is small, then rewriting it in a modern (and better supported that C++/CLI) system is the best thing. Qt is probably the ultimate in native GUIs nowadays (but there are alternatives such as MFC, or wxWidgets). Even in these cases, its still probably better to code your networking subsystem as a native library anyway. Then you can change your GUI and try out a load of the GUI stacks as you like, porting your game to Android or iOS with just 1 presentation layer change.

The third alternative is to choose a different comms system. Whilst RPC like ICE are nice, the 'where its at' today is web-based comms via REST services (try an embedded c++ webserver like Mongoose or NxWeb), if you need to push data back to the client, these support WebSockets, so will provide all the functionality you need. And then, you can rewrite your GUI to be HTML based!

So: put your comms in a native C++ library.

3760600 0 Can android Emulate a HID device?

I was attempting to design an app that would allow me to have android emulate a hardware device.
I.E. a generic keyboard, a generic mouse.

I could essentially plug in my android (HTC) to a computer, and program it to use a software keyboard as the computers hardware keyboard.

I don't have any direction on how to accomplish this.

I only wish to connect USB(not bluetooth). So that the computer needs 0 installation before working. And most devices will work in Dos Mode.

38852460 0 Login page redirect new page if sucess

My application uses Mithril.js and Play Framework.

I would like to know if there is a (good) way to divide my application between mithril and play. I would like to have play renders a login.html, this login.html will only contain only the import of my mithril.js component (login.js). If the login is a success I would like play to redirect my application to another html page. This pages will contain all the imports of all my mithril's components.

So my application will have only two html pages on the play framework side, one which imports only one mithril component and the other which import all the others components (only if credentials are checked).

Play router :

GET / controllers.Index.index
Play controller :

def index = Action { Ok(views.html.login()) }

<!DOCTYPE html> <html lang="en"> <head> <title>IHM</title> StylesSheet import.. </head> <body id="app" class="body"> <script src="https://cdnjs.cloudflare.com/ajax/libs/mithril/0.2.2-rc.1/mithril.min.js"></script> <script src="@routes.Assets.versioned("javascripts/claravista/login.js")" type="text/javascript"></script> <script type="text/javascript"> m.route.mode = "pathname"; m.route(document.getElementById('app'), "/", { "/": login, }); </script> </body>

Mithril ask play check credentials (in component login)

m.request({method: "PUT", url: "/check-user", data : login.user }).then(returnCall);
Case Credentials false : ask again (I already did this part)

Case Credentials true : redirect to another html page (How to do this?)

<!DOCTYPE html> <html lang="en"> <head> <title>IHM</title> </head> <body id="appmain" class="body"> <script src="https://cdnjs.cloudflare.com/ajax/libs/mithril/0.2.2-rc.1/mithril.min.js"></script> ALL MY MITHRIL COMPONENTS IMPORT <script type="text/javascript"> m.route.mode = "pathname"; m.route(document.getElementById('appmain'), "/main", { "/main": main, }); </script>

How can I redirect to another html page after credentials are checked? Is there a better way to prevent the server to send all the JavaScript files before the user is logged?

40367483 1 Python determine whether an exception was thrown (regardless of whether it is caught or not)

I am writing tests for some legacy code that is littered with catch-all constructs like

try: do_something() do_something_else() for x in some_huge_list(): do_more_things() except Exception: pass

and I want to tell whether an exception was thrown inside the try block.

I want to avoid introducing changes into the codebase just to support a few tests and I don't want to make the except cases more specific for fear of unintentionally introducing regressions.

Is there a way of extracting information about exceptions that were raised and subsequently handled from the runtime? Or some function with a similar API to eval/exec/apply/call that either records information on every raised exception, lets the user supply an exception handler that gets run first, or lets the user register a callback that gets run on events like an exception being raised or caught.

If there isn't a way to detect whether an exception was thrown without getting under the (C)Python runtime in a really nasty way, what are some good strategies for testing code with catch-all exceptions inside the units you're testing?

19313839 0 C# Signal Processing Plotting Rapid Data

I have a circuit that sends me two different data from sensors. Data is coming as packets. First data is '$' to separate one packet to another. After '$' it sends 16 bytes microphone data and 1 byte pulse sensor data. I have an array to store incoming data and after plotting the data in each 20 ms, i start to write new bytes from zero index of array. I need to plot these data to different graphs using ZedGraph. However i could not separate those data correctly. Sometimes one or more data of audio are shown in other graph. Here is my code:

 for (int i = 0; i < 4; i++) { if (data[i * 18] == Convert.ToByte('$')) { for (int x = ((i * 18) + 1); x < ((i * 18) + 17); x++) { listAuido.Add(time, data[x]); } for (int a = ((i * 18) + 17); a < ((i * 18) + 18); a++) { listPulse.Add(time, data[a]); } } }

How can i solve this issue?

Circuit settings: BaudRate: 38400, Frequency: 200hz, CommunicationType: RS232.

Port Settings:ReadTimeOut=5 WrtieTimeOut=5;

While reading data i am using codes below. Read_Data1 refers data[] the code above. I have a counter and after plotting the data its value equals zero and i prevent my buffer index out of range exception

 byte[] Read_Data1 = new byte[1000]; private void myPort_DataReceived(object sender, SerialDataReceivedEventArgs e) { if (!myPort.IsOpen) return; if (myPort.BytesToRead > 0) { byte[] buffer = new byte[myPort.BytesToRead]; myPort.Read(buffer, 0, buffer.Length); DataConversion.bytetobyte(Read_Data1, buffer, buffer.Length, count); count += buffer.Length; DataRecord.SaveBytesToFile(buffer, save.FileName); } } public static void bytetobyte(byte[] Storage, byte[] databyte, int datacount, int count) { int abc; for (abc = 0; abc < datacount; abc++) { Storage[abc + count] = databyte[abc]; } }

There are many scenarios when you need culture based formatting.

For example: - Number Format

5.25 in English is written as 5,25 in French

So, if you want to display French formatted number in your program which is in English culture the culture based string format comes into action.

I would guess they outer join their friends table with their likes table to count both regular likes and friend likes at the same time.

With the proper indexes, it wouldn't be a slow query at all. Huge databases aren't necessarily slow, so there's really no reason to not store all of this information in a database. The trick is to make sure the indexes and partitions (if any) are set up well.

It's a good idea to see the coverage of your tests as it can point to problems. If your test code isn't being run then there wasn't much point in writing it!

The one I always get is when I give two unit test functions the same name - I add a new test several months after the original and just happen to pick the same name. The unittest framework won't complain about this - one of the functions hides the other and it just won't run one of the tests! The detailed coverage report shows the problem immediately though.

If you have other code in your tests that isn't being run then that may also point to other bugs, although typically there's often a couple of lines of boilerplate code that might not get covered depending on how the tests get invoked, so don't obsess about getting to 100%.

And if you have test code that really isn't needed any more then it's always good to delete!

Why, you can still static assert with const int:

#define static_assert(e) extern char (*ct_assert(void)) [sizeof(char[1 - 2*!(e)])] static_assert( THIS_LIMIT > OTHER_LIMIT )

Also, use boost!

BOOST_STATIC_ASSERT( THIS_LIMIT > OTHER_LIMIT )

... you'll get a lot nicer error messages...

Use a loop statement:

decode_process: process(clk) -- synchronous reset, no rst in sensitivity list begin if clk'event and clk = '1' then if rst = '1' then out_address <= (others => '0'); else for i in 0 to 10 loop if i = to_integer(unsigned(in_address)) then out_address(i) <= '1'; else out_address(i) <= '0' ; end if; end loop; -- name: for i in 0 to 10 generate -- if (i = to_integer(unsigned(in_address))) then -- out_address(i) <= '1'; -- else -- out_address(i) <= '0'; -- end if; -- end generate name; end if; end if; end process;

Also notice rst was removed from the sensitivity list, it's written as a synchronous reset.

A loop statement can be synthesized, see now rescinded IEEE Std 1076.6-2004 8.8.9, Syntax, Sequential statements, Loop statement or your particular synthesis vendor's tool documentation. The sequential statements found in a loop are replicated for each value of the loop parameter which is treated as a constant.

So what's the difference between generate iteration and loop iteration?

Simulation cycles emulate concurrency for signal assignments even in sequential statements (e.g. in a process). There are no dependencies between one if statement and another in the synthesized (unrolled) loop. They will be i number of in_address recognizers comparing i to in_address each providing one bit of out_address. The first one assigning a(0), the second a(1)... In this case the loop statement will produce the same logic a generate statement would (using conditional signal assignment, although the sequential logic (clock) semantics would make it look awkward).

Let's compare this to using a generate statement in a concurrent statement appropriate place:

architecture foo of address_decoder is function to_std_ulogic (inp: boolean) return std_ulogic is begin if inp = TRUE then return '1'; else return '0'; end if; end; begin decoder: for i in 0 to 10 generate out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))) when clk'event and clk = '1'; end generate; end architecture;

The function to_std_ulogic taking a boolean argument has been added for brevity in the conditional signal assignment statement to out_address(i).

This looks nice and compact and may likely synthesize depending on the ability to use the function converting a boolean to a std_ulogic.

However, it expands out for elaboration:

architecture fum of address_decoder is function to_std_ulogic (inp: boolean) return std_ulogic is begin if inp = TRUE then return '1'; else return '0'; end if; end; begin decoder0: block constant i: integer := 0; begin out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))) when clk'event and clk = '1'; end block; decoder1: block constant i: integer := 1; begin out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))) when clk'event and clk = '1'; end block; decoder2: block constant i: integer := 2; begin out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))) when clk'event and clk = '1'; end block; decoder3: block constant i: integer := 3; begin out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))) when clk'event and clk = '1'; end block; decoder4: block constant i: integer := 4; begin out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))) when clk'event and clk = '1'; end block; decoder5: block constant i: integer := 5; begin out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))) when clk'event and clk = '1'; end block; decoder6: block constant i: integer := 6; begin out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))) when clk'event and clk = '1'; end block; decoder7: block constant i: integer := 7; begin out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))) when clk'event and clk = '1'; end block; decoder8: block constant i: integer := 8; begin out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))) when clk'event and clk = '1'; end block; decoder9: block constant i: integer := 9; begin out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))) when clk'event and clk = '1'; end block; decoder10: block constant i: integer := 10; begin out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))) when clk'event and clk = '1'; end block; end architecture;

And worse still, each of those block statement concurrent conditional signal assignment statements become a process statement of the form:

decoder10: block constant i: integer := 10; begin process begin if clk'event and clk = '1' then out_address(i) <= to_std_ulogic(i = to_integer(unsigned(in_address))); end if; wait on clk, in_address; end process;

So now all the sudden instead of simulating one process you have eleven and each of those processes is sensitive to both clk and in_address, meaning the process with become active more than on just both clock edges.

So not only do the loop statement and the generate statement equivalent produce the same hardware after elaboration and synthesis, the loop statement is guaranteed to be faster in simulation, which is it's intended purpose.

Everything in a VHDL design specification devolves into block statements, process statements and subprograms (functions, procedures). Concurrent procedures are also devolved, while functions are expressions.

It's guaranteed that synthesis elaborates a design first. The synthesis difference in this case between the generate statement and a single process containing a loop is grouping. A process statement is translated separately unless a synthesis tool accepts an attribute allowing flattening (e.g. DISSOLVE_HIERARCHY as an attribute on the generate statement).

In the loop statement in a single process case you have the opportunity to share address recognizer logic between the 10 signal assignments by default, potentially generating less logic.

So there can be little difference in synthesis, but a significant difference in simulation, where the practical impact depends on the size of your design.

Note the Statement documentation says:

By default, only one ResultSet object per Statement object can be open at the same time.

Now, you have these statements in your program:

ResultSet resultset = statement.executeQuery("select * from customer where first_name = '" + first_name + "'") ; statement.executeQuery("select * from customer where last_name = '" + last_name + "'") ; statement.executeQuery("select * from customer_order where amount = '" + amount + "'") ; statement.executeQuery("select * from customer_order where date_created = '" + date_created + "'") ; statement.executeQuery("select * from customer_order where reference_number = '" + reference_number + "'") ; statement.executeQuery("select * from customer_order where invoice_number = '" + invoice_number + "'") ; statement.executeQuery("select * from customer_order where status = '" + status + "'") ; statement.executeQuery("select * from ordered_product where quantity = '" + quantity + "'") ; statement.executeQuery("select * from ordered_product where product_name = '" + product_name + "'") ; statement.executeQuery("select * from ordered_product where product_price = '" + product_price + "'") ;

This means you are calling the executeQuery several times with the same Statement object. But you are only saving the result of the first execution into resultset.

That is, the ResultSet object that resultset refers to is the one from this statement:

statement.executeQuery("select * from customer where first_name = '" + first_name + "'") ;

All the others that follow it are separate queries and are not stored in the same variable if that's what you thought you were doing. They just create the ResultSet object, and then it gets thrown away because you don't assign the result to any variable.

As soon as you call the second executeQuery, because only one ResultSet object is allowed, the ResultSet object stored in resultset is closed, and a new one is opened. Then another, and then another.

Anyway, after you go through all these statements, you get to the part where you check resultset.next(). But at this point, that object, as I said, has already been closed.

Basically, you should decide which of the queries you want to run, run only that particular query, and then you'll have a live, open ResultSet in resultset. And then you can fill it in.

In addition, the part that prints the values from the result set should be inside the else block. You placed them after the curly brace of that else, which means you'll have trouble when no rows are returned from the query, because you'll be trying to print them anyway.

Looking at your code it appears there are 2 errors with your JSON. In it's original for it produces the follwoing string:

{"guid" : "26fac319-604b-11e5-b1fe", "senderid" : "003001", "campaign" : Weekday_EGV_21Sept_4pm_Round2_Tier1_Part1}}

You are missing quotes around that final field value of campaign and you have an extra } at the end. If you make the following change:

json_body = "{\"guid\" : \""+ guid+"\", \"senderid\" : \""+ senderid+"\", \"campaign\" : \""+ str(campaign)+"\"}"

it should resolve the JsonParseException error.

I saw a way to do the transition via javascript so might have to just do that.

But then I have a ...... part b to this question. Can anyone guess why the 2nd and 3rd image boxes get a thin black line between them when you hover over them?

Here is plugins: PluginWithOutException

namespace PluginWithOutException { public class WithOutException : MarshalByRefObject, ICommonInterface { public void ShowDllName() { MessageBox.Show("PluginWithOutException"); } public WithOutException() { } } }

and another one: PluginWithException

namespace PluginWithException { public class WithException : MarshalByRefObject, ICommonInterface { public void ShowDllName() { MessageBox.Show("WithException"); throw new NotImplementedException(); } } }

And here is an application, which loads DLLs and runs them in another AppDomain's

namespace Plug_inApp { class Program { static void Main(string[] args) { ThreadPool.QueueUserWorkItem(CreateDomainAndLoadAssebly, @"E:\Plugins\PluginWithException.dll"); Console.ReadKey(); } public static void CreateDomainAndLoadAssebly(object name) { string assemblyName = (string)name; Assembly assemblyToLoad = null; AppDomain domain = AppDomain.CreateDomain(string.Format("{0} Domain", assemblyName)); domain.FirstChanceException += domain_FirstChanceException; try { assemblyToLoad = Assembly.LoadFrom(assemblyName); } catch (FileNotFoundException) { MessageBox.Show("Can't find assembly!"); throw; } var theClassTypes = from t in assemblyToLoad.GetTypes() where t.IsClass && (t.GetInterface("ICommonInterface") != null) select t; foreach (Type type in theClassTypes) { ICommonInterface instance = (ICommonInterface)domain.CreateInstanceFromAndUnwrap(assemblyName, type.FullName); instance.ShowDllName(); } } static void domain_FirstChanceException(object sender, System.Runtime.ExceptionServices.FirstChanceExceptionEventArgs e) { MessageBox.Show(e.Exception.Message); } } }

I expect, that if I run instance.ShowDllName(); in another domain (maybe I do it wrong?) the unhandled exception will drop the domain where it runs, but the default domain will work. But in my case - default domain crashes after exception occurs in another domain. Please, tell me what I'm doing wrong?

13040600 0 Why is joining two vectors simply not working?

I have two vectors of MyObj structs. MyObj is defined as follows:

struct MyObj { float x, y; unsigned int data[8]; unsigned int tmp[1]; MyObj(const MyObj &m) { x = m.x; y = m.y; tmp[0] = 0; for (int i = 0; i < 8; ++i) { data[i] = m.data[i]; } } };

I then have two vectors...

vector<MyObj> v1; vector<MyObj> v2; // both get data eventually. v1.insert(v1.end(), v2.begin(), v2.end());

v2 has 3535004 elements in my experiment. v1 is similarly sized. I've also tried building a new vector and just using .push_back to build it from both vectors.

Essentially, when I try to merge the two vectors I just get an error from visual studio saying "Debug error! R6010, abort() has been called". Very non-useful...

So my question is: what could be causing this error, and how can I solve it? Thank you

On Windows you can use the low level bitmap copying functions, which accurate match the old description without any OpenGL, etc.

BOOL BitBlt( _In_ HDC hdcDest, _In_ int nXDest, _In_ int nYDest, _In_ int nWidth, _In_ int nHeight, _In_ HDC hdcSrc, _In_ int nXSrc, _In_ int nYSrc, _In_ DWORD dwRop );

You have an incorrect understanding of the shared folder. It is not a place to put files you wish to have copied to the build output folder. The folder you are looking for is entitled assets those files will be copied to the output directory, dist for both dev and prod builds.

The shared directory is a place to put common (or shared) portions of your application, whether they be components, directives, pipes, classes or services.

11504746 0 MYSQL SELECT SUM() BY DATE IF NO MATCH RETURN 0

I have connected three tables to each other. I'm querying keywords + statistics.

I need to get data out by date range, and if there is no data for that specific date range i would like it to return 0 statistics

Lets say my query is:
SELECT keyword,SUM(stat) FROM keywords WHERE date >='2012-07-10' GROUP BY keyword;

It would return
|my keyword 1|3|
|my keyword 2|6|

Example table content:
| id | keyword | stat | date | keywordGroup |
| 1 | my keyword 1 | 2 | 2012-07-11 | 1 |
| 2 | my keyword 1 | 1 | 2012-07-12 | 1 |
| 3 | my keyword 2 | 6 | 2012-07-11 | 1 |
| 4 | my keyword 3 | 10 | 2012-07-09 | 1 |

But there are some keywords which have no stats for that date range
but I would still like to get those keywords showing 0 as stats.

Like this:

|my keyword 1|3|
|my keyword 2|6|
|my keyword 3|0|

The problem is that the where clause blocks values that are not found, is there a workaround.
As I said I have three tables with relations, I use LEFT JOIN to query data, for simplification I left that part out of my example query.

Table: Campaigns
id
name

Table: KeywordGroup
id
name
campaign

Table: KeywordData
id
keyword
stat
date
keywordGroup

Your row variable is not the a tag, so there is no attribute href on it.

Try with this:

Element table = doc.select("table.table"); Elements links = table.getElementsByTag("a"); for (Element link: links) { String url = link.attr("href"); String text = link.text(); System.out.println(text + ", " + url); }

This is pretty much extracted from the JSoup documentation

Basically you want to implement a set; check the list manual page for set operations. It appears that there is no add but there is union/3 so you can add elements by intersecting with a set of the new element (intersection([NewEl], OldSet, NewSet). Note that you dont have to convert a list to a set (a list is a set as long as it doesnt have duplicates; list_to_set/2 just eliminates them).

Now if you have a list with duplicates and you want sometimes to add an element the way you stated you will have to implement something yourself.

The error lines say

#if defined(_AMD64_) || defined(_X86_) #define PROBE_ALIGNMENT( _s ) TYPE_ALIGNMENT( DWORD ) #elif defined(_IA64_) || defined(_ARM_) #define PROBE_ALIGNMENT( _s ) (TYPE_ALIGNMENT( _s ) > TYPE_ALIGNMENT( DWORD ) ? \ TYPE_ALIGNMENT( _s ) : TYPE_ALIGNMENT( DWORD )) #elif !defined(RC_INVOKED) #error "No Target Architecture" #endif

You have #included that header, possibly indirectly by including another header. You can tell VS2012 to list all the includes it uses by setting "Show Includes" to yes in the Properties | C/C++ | Advanced project menu. Then try not including the header that is dragging in winnt.h if you don't need it.

winnt.h can cause trouble e.g. see here

edit
So, the precompile header includes windef.h which includes the offending header. Try removing the line from the precompiled header.

Sure, just follow a few easy steps:

1. Put your models in a shared directory

For example, if your current directory structure looks like this:

/www /application1 /protected /models /application2 /protected /models

Create another "shared" directory. It's a good idea to put some structure in there as well, in case you want to share more than just some models:

/www /application1 /protected /models /application2 /protected /models /shared /models

Put the active record models you want to share in /www/shared/models.

2. Alias the shared directory in both applications

Go to your main.php configuration file in both applications and create an alias for the shared directory:

Yii::setPathOfAlias('shared','../shared/'); // or use an absolute path

3. Import shared models

Still in your main.php configuration, import your shared models:

'import'=>array( // ...existing imports here... 'shared.models.*', ),

You can now directly refer to the shared classes anywhere in your application and Yii will load the appropriate classes automatically.

If you later add more directories to /shared then simply add corresponding lines to the import configuration.

40613048 0 MySql: create procedure error

I'm trying to create a stored procedure, either in command line or MySql Workbench editor.

In Mysql WOrkbench I have no message at all, no success no error, but the procedure is not created. In command line mysql --host=localhost ... < procedure-script.sql I get the following error:

ERROR 1064 (42000) at line 4: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER' at line 28

Line 28 is actually empty but I guess it refers to the final DELIMITER ; in line 31. Here is the complete code:

DELIMITER $$; -- drop procedure if exists updPages$$ CREATE PROCEDURE updPages() BEGIN DECLARE _post_id INTEGER; DECLARE cur_pages CURSOR FOR select ID from wp_posts where post_type='page' and ID not in (select post_id from wp_postmeta); OPEN cur_pages; Reading_Pages: LOOP FETCH cur_pages INTO _post_id; IF done THEN LEAVE Reading_Pages; END IF; insert into wp_postmeta(post_id, meta_key, meta_value) values (_post_id, '_wp_page_template', 'default'), (_post_id, 'upside-show-page-title', '1'), (_post_id, 'upside-show-breadcrumb', '1'), (_post_id, 'upside-page-show-document-search', '0'), (_post_id, 'upside-show-page-title-middle', 'false'), (_post_id, '_vc_post_settings', 'a:1:{s:10:"vc_grid_id";a:0:{}}'); END LOOP; CLOSE cur_pages; END$$ DELIMITER ;

(1) Is there any error? (2) Do you know how to show compilation errors in Mysql Workbench? also, (3) can I use tab inside scripts when running them from command line? (I had to strip them out as I had errors)

Try changing your ng-options to something like:

<select class="form-control" id="Event_Cat" data-ng-model="vm.selectedCategory" data-ng-options="opt.id as opt.label for opt in categoryValues | orderBy:'label'" required> <option style="display:none" value="">Select a Category</option> </select>

And make this line change in your controller:

$scope.vm.selectedCategory = $scope.categoryValues[currentDetailIndex].id;

Edit for multiple selection:

<select class="form-control" id="Event_Cat" data-ng-model="selectedCategoriesIds" data-ng-options="opt.id as opt.label for opt in categoryValues | orderBy:'label'" required multiple> <option style="display:none" value="">Select a Category</option> </select>

In your controller, add the items you want selected to $scope.selectedCategoriesIds e.g.:

$scope.selectedCategoriesIds = []; $scope.selectedCategoriesIds.push('18'); $scope.selectedCategoriesIds.push('80');

The exact sql query depends on what type of SQL server you have used.

For example in MySQL you can paginate by LIMIT and OFFSET at the end of a query.

SELECT something FROM table LIMIT 20, 40

It says that you get 20 records from 40. position.

Turn on tracing

You can turn on tracing on a single page using the Trace attribute in the Page directive.

<%@ Page Trace="true" %>

You can also turn on tracing for all pages in an asp.net application using the web.config setting.

<configuration> <system.web> <trace enabled="true" pageOutput="false" requestLimit="40" localOnly="false"/> </system.web> </configuration>

Add custom output to the trace output.

public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Trace.Write("custom start"); System.Threading.Thread.Sleep(2000); Trace.Write("custom end"); } }

897206 1 Python cgi FieldStorage slow, alternatives?

I have a python cgi script that receives files uploaded via a http post. The files can be large (300+ Mb). The thing is, cgi.FieldStorage() is incredibly slow for getting the file (a 300Mb file took 6 minutes to be "received"). Doing the same by just reading the stdin took around 15 seconds. The problem with the latter is, i would have to parse the data myself if there are multiple fields that are posted.

Are there any faster alternatives to FieldStorage()?

Your description does not really match with the Memento patttern. The whole point of Memento is that only instances of the class which is to be restored know anything about the representation of the memento. That is, Memento is about hiding state, rather than allowing clients to set arbitrary states.

As Mark Cidade suggests above, there are other more appropriate patterns to use for your problem.

9409634 0 Is indexing of Data.Vector.Unboxed.Mutable.MVector really this slow?

I have an application that spends about 80% of its time computing the centroid of a large list (10^7) of high dimensional vectors (dim=100) using the Kahan summation algorithm. I have done my best at optimizing the summation, but it is still 20x slower than an equivalent C implementation. Profiling indicates that the culprits are the unsafeRead and unsafeWrite functions from Data.Vector.Unboxed.Mutable. My question is: are these functions really this slow or am I misunderstanding the profiling statistics?

Here are the two implementations. The Haskell one is compiled with ghc-7.0.3 using the llvm backend. The C one is compiled with llvm-gcc.

Update 1: I un-inlined kahanStep in the C version. It barely made a dent in the performance. I hope that now we can all acknowledge Amdahl's law and move on. As inefficient as kahanStep might be, unsafeRead and unsafeWrite are 9-10x slower. I was hoping someone could shed some light on the possible causes of that fact.

Also, I should say that since I am interacting with a library that uses Data.Vector.Unboxed, so I am kinda married to it at this point, and parting with it would be very traumatic :-)

Update 2: I guess I was not clear enough in my original question. I am not looking for ways to speed up this microbenchmark. I am looking for an explanation of the counter intuitive profiling stats, so I can decide whether or not to file a bug report against vector.

Not really anything to do with jQuery, but if you want to trim a pattern from a string, then use a regular expression:

<textarea id="ta0"></textarea> <button onclick=" var ta = document.getElementById('ta0'); var text = 'some<br>text<br />to<br/>replace'; var re = /<br *\/?>/gi; ta.value = text.replace(re, '\n'); ">Add stuff to text area</button>

So what your code is doing is the following:

x = '2', which represents 50 as a decimal value in the ASCII table.

then your are basically saying:

x = x - '0', where zero in the ASCII table is represented as 48 in decimal, which equates to x = 50 - 48 = 2.

Note that 2 != '2' . If you look up 2(decimal) in the ASCII table that will give you a STX (start of text). This is what your code is doing. So keep in mind that the subtraction is taking place on the decimal value of the char.

31172837 0 "Regular Expression is too large" error in PHP

I am working on a relatively complex, and very large regular expression. It is currently 41,127 characters, and may grow somewhat as additional cases may be added. I am starting to get this error in PHP:

preg_match_all(): Compilation failed: regular expression is too large at offset 41123

Is there a way to increase the size limit? The following settings suggested elsewhere did NOT work because these apply to size of data and NOT the regex size:

ini_set("pcre.backtrack_limit", "100000000"); ini_set("pcre.recursion_limit", "100000000");

Alternatively, is there a way to define a "sub-pattern variable" within the regex that could be repeated at various places within the regex? (I am not talking about repetition using * or +, or even repeating matched "1")? I am actually using PHP variables containing sub-Patterns that are repeated in few places within the regex, but this leads to expansion of the regex BEFORE it is passed on to PRCE functions.

This is a complex regular expression, and cannot be replaced by simpler keyword-searching using strpos or similar as suggested at this link.

I would prefer to avoid splitting this into sub-expressions at | and trying to match the sub-expressions separately, because the reduction in size would be modest (there are only 2 or 3 of top-level |), and this would complicate further development.

I can tell you right off that bat you are approaching a simple problem with an incredibly complex solution...

I would guess you are looking for the instanceof keyword, or perhaps an abstract validation class.

If you could be more specific with your intended functionality we could help you come up with a reasonable design pattern.

Directly to your question: Yes, you can generate and load classes in Java on the fly. It involves invoking the defineClass(String, byte[], int, int) method in the reflection package. As input to this function you have to provide a byte array of the class you are instantiating. This doesn't sound like the appropriate approach to this problem.

You can just disable/uninstall bzr-svn plugin if you don't need to work with svn servers from bzr.

Or, in the command-line execute following command:

bzr --no-plugins init

It will create bzr branch in your directory, and after that bzr and TortoiseBzr won't try to open svn working copy.

But you probably still will have problems when running bzr commands from subfolders. So, you can add all required files in your svn copy under bzr version control, then commit them:

bzr add bzr commit -m initial

Now you can re-create this state of files in different (empty) directory with

bzr branch path/to/bzr/branch/in/svn/copy new/path

And do all work in new/path. When you'll be ready to update your svn working copy with latest committed revision from new/path then just push your changes back:

bzr push path/to/bzr/branch/in/svn/copy

32164663 0 Convert JQuery QR Code to Image using JS

I was wondering how it's possible to download the JQuery generated QR code or convert to a downloadable image (png/jpeg) using javascript.

I tried what was here: Capture HTML Canvas as gif/jpg/png/pdf? But no success. I think it's related to the output. There is a table and canvas output, but both do not give the image data...

Here is my code:

<script src="js/jquery-1.3.2.js"></script> <script type="text/javascript" src="js/jquery.qrcode.js"></script> <script type="text/javascript" src="js/qrcode.js"></script> <div id="output"></div> <script> jQuery(function(){ jQuery('#output').qrcode("http://"); }) var canvas = document.getElementById("output"); var img = canvas.toDataURL("image/png"); document.write('<img src="'+img+'"/>'); </script>

Also I was hoping to surround the QR Code with a white background (Adding rows and columns within the div) before converting to image to aid the detection (so that the background is also included in the image).

Any help is appreciated...

40541157 0 How to test channel with Phoenix.ChannelTest.close/2

I have a test that starts up a socket connection and subscribes and joins a topic. I then push a message to the channel which does some work and persist some data. I then use ChannelTest.close/2 on the socket which simulates the client closing the connection. I would then like to modify the manipulated data and create another socket connection to test some behaviour.

My issue is ChannelTest.close/2 causes my test to fail and returns ** (EXIT from #PID<0.558.0>) shutdown: :closed. How can I prevent this from happening?

Here's some relevant code

defmodule PlexServer.EmpireChannelTest do use PlexServer.ChannelCase alias PlexServer.EmpireChannel alias PlexServer.EmpireTemplate alias PlexServer.EmpireInstance setup do ... {:ok, _, socket} = socket("user_id", %{}) |> subscribe_and_join(EmpireChannel, "empire:#{empire.id}", %{"guardian_token" => jwt}) {:ok, socket: socket, empire: empire, jwt: jwt} end test "research infrastructure", %{socket: socket, empire: empire, jwt: jwt} do ... ref = push socket, "command", request assert_reply ref, :ok, _, 1000 close(socket) #fails here ... end end defmodule PlexServer.UserSocket do use Phoenix.Socket use Guardian.Phoenix.Socket ## Channels # channel "rooms:*", PlexServer.RoomChannel channel "empire:*", PlexServer.EmpireChannel channel "user:*", PlexServer.UserChannel ## Transports transport :websocket, Phoenix.Transports.WebSocket def connect(_params,_) do :error end def id(_socket), do: nil end defmodule PlexServer.EmpireChannel do use PlexServer.Web, :channel use Guardian.Channel alias PlexServer.EmpireInstance alias PlexServer.EmpireServer ... def join("empire:" <> empire_id, %{claims: _claims, resource: user}, socket) do ... #Starts a process through a supervisor here end def join("empire:" <> _, _, _socket) do {:error, data_error(:auth, "not authorized, did you pass your jwt?")} end # Channels can be used in a request/response fashion # by sending replies to requests from the client def handle_in("ping", payload, socket) do {:reply, {:ok, payload}, socket} end def handle_in("show", _, socket) do ... end def handle_in("command", request, socket) do ... end def handle_in("remove", _, socket) do ... end def handle_in("ship_templates", _, socket) do ... end end

Following the answer linked in the comments I added some code:

Process.flag(:trap_exit, true) monitor_ref = Process.monitor(socket.channel_pid) close(socket)

Now I get a different error message: ** (exit) exited in: GenServer.call(PlexServer.EmpireSupervisor, {:terminate_child, :empire4}, :infinity) ** (EXIT) no process

22069334 0 In Java, does locking ensure correct order of reads and write to nonvolatile locations

Suppose I have a shared object of class:

class Shared { private int x = 0 ; private int y = 0 ; private Semaphore s = new Semaphore() ; public int readX() { s.p() ; int x0 = x ; s.v() ; return x0 ; } public void writeX(int x0) { s.p() ; x = x0 ; s.v() ; } public int readY() { s.p() ; int y0 = y ; s.v() ; return y0 ; } public void writeY(int y0) { s.p() ; y = y0 ; s.v() ; } }

Here Semaphore is a class that uses synchronized methods to provide mutual exclusion.

Now the following actions happen:

Thread 0 calls o.readX() and finds it to be 0.
Thread 1 writes 1 to x and then 1 to y using o.writeX(1) ; o.writeY(1) ;
Thread 0 calls o.readY() getting 1 and then calls o.readX() .

Could thread 0 read from its cache and find that x is 0? Why?

EDIT

Here is the Semaphore class

class Semaphore { private boolean available = true ; public synchronized void v() { available = true ; notifyAll() ; } public synchronized void p() { while( !available ) try{ wait() ; } catch(InterruptedException e){} available = false ; } }

AsyncTask enables proper and easy use of the UI thread. This class allows to perform background operations and publish results on the UI thread without having to manipulate threads and/or handlers.

AsyncTask is designed to be a helper class around Thread and Handler and does not constitute a generic threading framework. AsyncTasks should ideally be used for short operations (a few seconds at the most).

WARNING : The AsyncTask has an implicit reference to the enclosing Activity. If a configuration change happens the Activity instance that started the AsyncTask would be destroyed, but not GCd until the AsyncTask finishes. Since Activities are heavy this could lead to memory issues if several AsyncTasks are started. Another issue is that the result of the AsyncTask could be lost, if it's intended to act on the state of the Activity. Replace the AsyncTask by the new AsyncTaskLoader

Update:

GCC chokes on your function stringlength. Try this:

constexpr size_t stringlength(char const* str, size_t i=0) { return str ? (str[i] ? 1 + stringlength(str, i+1) : 0) : 0; }

To GCC 4.6.3 this seems dubious:

static constexpr int const* c = &a[0]; static constexpr int const* d = &b[0];

Try this:

static constexpr int* c = &a[0]; static constexpr int* d = &b[0];

Old answer:

You code seems to be correct and with GCC 4.6.3 it also compiles.

int main() { const char* a = "hallo"; const char* b = "qallo"; std::cout << is_equal(a,b,5) << std::endl; constexpr const char* c = "hallo"; std::cout << is_equal(a,c,5) << std::endl; }

Be careful, that the strings you are giving to your functions are constants.

See here what is allowed with constexpr.

8082358 0 RegisterStartupScript, Ajax and external script

I have a page that is run using AJAX. I have a control that is wrapped in a RadAjaxPanel that has multiple child controls in it. The RadAjaxPanel is updated when new items are selected. I also have a 3rd party javascript that needs to refresh during the callback.

Here is my problem.

When the callback happens, I use

ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "RecommendationScript", "<script src='3rdparty.js'></script>, false);

This doesn't appear to work after the callback happens since I am not seeing the results. Even if I create a test external script that does a javascript alert, I won't see the alert after the callback. Everything works fine though if I don't use an external script and just put the alert in the RegisterStartupScript. However, that won't work for what I need to do.

Any ideas?

you might ask why both this.unbind and this.el unbind. i did this way because i'm closing my view after model update, and if i remove this.el unbind the POST is going more than once, (zombie issue)

If all you want to do is capture the h.264 stream and stick it into a container, I would utilize FFmpeg. I don't know the exact command line, so this is untested but try something like...

ffmpeg -i - -f mp4 output.mp4

Then, write to it over STDIN. It should detect your stream type after several packets, and begin writing to the MP4 file.

That library doesn't look like it will easily do bidirectional. But, since DMX512 is a simple serial protocol, there's nothing stopping you from writing your own routines that manipulate the UART directly. The library will be a great guide for this.

Now, having said that: what kind of situation do you have where you want a device to both control and receive? The DMX512 protocol is explicitly unidirectional, and at the physical layer it's a daisy-chain network, which prevents multiple masters on the bus (and inherently creates a unidirectional bus). If you are a slave and you are manipulating the bus, you risk clobbering incoming packets from the master. If you are clever about it, and queue the incoming packets, you could then perhaps safely retransmit both the incoming data and your own data, but be aware that this is a decidedly nonstandard (and almost certainly standards-violating) behavior.

but it shouldn't affect globalPersonList. I want amount value only in my newPerson object. But right now this is set in globalPersonList also. after setting amount if I try to

globalPersonList.get("key").getAmount()

it is giving the amount that I set. Is it using the reference to new object? I want a seperate copy of Person object so that it won't affect main hashmap.

5409418 0 Common Lisp: how to dynamically wrap existing functions, such as for a profiler?

I am new at Lisp, and am trying different things out to improve my skills. I want to write a macro that wraps existing functions so that I can set up before and after forms for these functions, kind of like CLOS's auxilliary methods or Elisp's advice package. The trace function's ability to wrap code dynamically has intrigued me, and it seems useful to be able to do this myself.

So, how can I do this? How many ways can I do this? : )

Please note that I am using SBCL, and that, for the purposes of this question, I am not interested so much in the "right" way of doing this as I am in adding to my Lisp trick bag.

10518782 0 iOS and ARC : How to retain self during asynchronous operations?

It's the first time I'm fiddling around with iOS5 and ARC. So far, so good, it works, but I've run into some kind of a problem.

I have a custom UIStoryboardSegue in which I use Facebook Connect (or other services) to log the user into my app. Simply put, it should do the following :

User clicks on the button
Button fires the Segue
The segue starts asynchronous login but does not immediately push the view controller
If, and only if the login is successful, the segue pushes the view controller

What happens instead, is that the login starts, but the segue is immediately released by ARC before it has any chance to complete.

I thought of a quick'n'dirty hack to prevent this:

@interface BSLoginSegue() { __strong BSLoginSegue *_retained_self; } @end // Stuff... // Other stuff... - (void) perform { login(); _retained_self = self; } - (void) loginServiceDidSucceed:(BSLoginService *)svc { ... _retained_self = nil; }

The thing is, it really is a hack, so I was wondering if there were any other, and more elegant way I could do the same?

The list class is a linked list, you cannot directly index into it. Also, iterators are not indices, + just doesn't makes any sense.

However, in theory, you should be able to copy an iterator, if you change q = mboxes.begin() + p into q = p it should set q to be an iterator pointing to the same location of p, and that may just solve your problem.

for (list<Box>::iterator p = mBoxes.begin(); p != mBoxes.end(); p++) { for (list<Box>::iterator q = p, q++; q != mBoxes.end(); q++) { if (p->isIntersecting(q)) { p->changeDirection(); q->changeDirection(); } } }

the q++ should simply skip the current element so you don't compare an item against itself.

My experience with LabWindows CVI is that its built-in libraries are more geared to instrumentation (GPIB, analog and digital I/O, motion control, and so forth) and data display (GUI widgets like meters, sliders, switches, LEDs, simple graphs), rather than extensive libraries of numeric, statistical, or analytic routines. The development environment that comes with Labwindows CVI is pretty decent -- they have a drag-and-drop GUI building interface that makes it easy to position controls within windows and wire them up to your C code, if that matters to you.

But for your analytic needs, you might be better served with a product like Matlab or IDL, especially if your work is heavy on the plotting/visualization end of things.

If you want to stick with C, the GNU Scientific Library has a pretty extensive set of statistical and analytic routines.

each architecture has its own assembly language. and even within architectures there might be extensions which add extra commands (like the SSE extensions). Usually a Compiler can only create code for one architecture, and there might be optional flags which enable optimizations for the extensions. When these flags get enabled the program will usually only run on processors that support these extensions.

For programs and OS it usually means you should only use compiler options that are supported by all processors of the architecture they have to run on. If thats not optimized enough you have to deliver executables/libraries with multiple code paths for he different optimizations, and pick the right one at runtime.

You need to use 4545454545l or 4545454545L to qualify it as long. Be default , 4545454545 is an int literal and 4545454545 is out of range of int.

It is recommended to use uppercase alphabet L to avoid confusion , as l and 1 looks pretty similar

You can do :

if(Long.valueOf(4545454545l).equals(Long.parseLong(morse)) ){ System.out.println("2"); }

if(Long.parseLong(morse) == 4545454545l){ System.out.println("2"); }

As per JLS 3.10.1:

An integer literal is of type long if it is suffixed with an ASCII letter L or l (ell); otherwise it is of type int (§4.2.1).

I have recently noticed the nice dashes that Google Places puts around cities, regions, states etc. I've been hunting around in the Google Maps API and the Google Places API trying to find out how to access the information thus displayed, without success.

I've discovered that Twitter has a nice API for this and I would be tempted to use that instead of Google's, but I worry that the lines that Google draw and the lines that Twitter draw may not correspond.

Is it safe to assume that both companies are using the same data? If not, where do I find the appropriate API information for the Google implementation?

Alternatively, where do I find the geodata they're both using?

PLEASE NOTE I'm asking about this in the context of Australian geodata. Do Google and Twitter use the same or different resources?

Each then callback is called in order, and the promise will wait when a new promise is returned in the previous callback. The problem with your code is that promises do not wait for css animations. And since it does not wait it goes to the next callback and removes your element right away.

You can create(and return) a new promise in the first then, and for that promise use a transitionend event listener to resolve/reject that new promise. This will make the promise wait till the transition is done and then execute the next callback

var prom = new Promise(function(res,rej){ var xhttp = new XMLHttpRequest(); xhttp.open("GET", "https://cors-test.appspot.com/test", true); xhttp.onload=function(){ console.log("loaded"); if(xhttp.status==200){ res(xhttp.response) } else{ rej(Error(xhttp.responseText)) } } xhttp.send(); }); prom.then(function(data){ var old = document.querySelector("#content"); return new Promise(function(res,rej){ old.addEventListener("transitionend",function(){ res(data); }); old.classList.add("remove"); }); }).then(function(data){ var parent = document.querySelector("#parent"); var old = document.querySelector("#content"); old.remove(); var div=document.createElement("div"); div.innerHTML="Data retrieved, length: "+data.length; parent.appendChild(div); });

.remove { opacity:0; } #parent div { -o-transition:all 2s; -moz-transition:all 2s; -webkit-transition:all 2s; transition:all 2s; }

36348763 0 How Do I Call an Async Method from a Non-Async Method?

I have the below method:

 public string RetrieveHolidayDatesFromSource() { var result = this.RetrieveHolidayDatesFromSourceAsync(); /** Do stuff **/ var returnedResult = this.TransformResults(result.Result); /** Where result gets used **/ return returnedResult; } private async Task<string> RetrieveHolidayDatesFromSourceAsync() { using (var httpClient = new HttpClient()) { var json = await httpClient.GetStringAsync(SourceURI); return json; } }

The above does not work and seems to not return any results properly. I am not sure where I am missing a statement to force the await of a result? I want the RetrieveHolidayDatesFromSource() method to return a string.

The below works fine but it is synchronous and I believe it can be improved upon? Note that the below is synchronous in which I would like to change to Asynchronous but am unable to wrap my head around for some reason.

 public string RetrieveHolidayDatesFromSource() { var result = this.RetrieveHolidayDatesFromSourceAsync(); /** Do Stuff **/ var returnedResult = this.TransformResults(result); /** This is where Result is actually used**/ return returnedResult; } private string RetrieveHolidayDatesFromSourceAsync() { using (var httpClient = new HttpClient()) { var json = httpClient.GetStringAsync(SourceURI); return json.Result; } }

Am I missing something?

Note: For some reason, when I breakpoint the above Async Method, when it gets to the line "var json = await httpClient.GetStringAsync(SourceURI)" it just goes out of breakpoint and I can't go back into the method.

That would allow some kind of proxy-copy like this:

NotCopyable a, b; b = a; // Made a copy of a

It is pretty unlikely that you do not want copy construction but copy assignment. Move assignment would be a different deal of course, see e.g. std::unique_ptr.

Singleton is basically the same. Why allow the self assignment? That just does not make sense.

You can use params to specify start_year and end_year of your select. Example:

<div class="field"> <%= f.label "Fecha de nacimiento:" %> <%= f.date_select :fecha_nacimiento, :start_year => 1950, :end_year => (Time.now.year - 10) %> </div>

Look at :end_year, I used Time.now.year - 10 because I assumed that the minimum age to register is 10 years old.

23560149 0 Android adding information to a table when the alarm started

Hi stackoverflow users I have the next problem: I have created a program that compare in a countdown timer 2 values( a feedback and a counter ) The counter is the value I set of the temperature for example and the feedback another value I get from outside.

When the countdown timer reach 0 if the counter is not equal with the feedback value the alarm start and I want to add the feedback and the counter to a log.

Example of a small piece of code is below, here I compare the counter with

if(Integer.parseInt(feedback.getText().toString()) != midvalue) { btnbool.setBackgroundColor(Color.RED); btnbool.setText("FALSE"); showup.setText(""+counter); letme = 2; if(alarmapornita == 0) { alarmapornita = 1; handler.post(thread); } alarma = 1; myhandler.post(mythread); healthy = false; Intent i = new Intent(getApplicationContext(), Log.class); i.putExtra("mymidvalue",midvalue); i.putExtra("myfeedback",Integer.parseInt(feedback.getText().toString())); startActivity(i); }

The problem is that with Intent I get only one entry to the table and when I get the alarm on it switch to the other activity. I don't know anything else how to use, is there any option to replace intent ?

You're experiencing one-off errors because of the fact that ExcelApp.Cells isn't zero based and you have a header row.

To combat this you can use foreach and separate out your header export to a separate block. It does take a little bit more code but I find it easier to deal with and less error prone

int i = 1; int j = 1; //header row foreach(DataColumn col in dtMainSQLData.Columns) { ExcelApp.Cells[i, j] = col.ColumnName; j++; } i++; //data rows foreach(DataRow row in dtMainSQLData.Rows) { for (int k = 1; k < dtMainSQLData.Columns.Count + 1; k++) { ExcelApp.Cells[i, k] = row[k-1].ToString(); } i++; }

Where he exports it using exports.start = start;

When I was reading another topics about module exports people there used it like:

module.export = moduleName

It's probably pretty simple, but Please can you please clarify it for me?

Is there some difference and what is behind the scenes? :)

I am using the ENUM sorting routine found at http://datatables.net/plug-ins/sorting. I would like to reuse that same function to sort another list outside of the DataTables plug-in (basically sorting a SELECT element on the same page as the DataTable). I want to avoid having to copy-and-paste (and maintain two sets of business rules) the features of the sort function.

For example, if this is the "plug-in" I'm using for DataTables:

jQuery.extend(jQuery.fn.dataTableExt.oSort, { "status-enum-pre": function (a) { switch (a) { case "Assigned": return 1; case "Contacted": return 2; case "Meeting Set": return 3; case "Closed": return 4; default: return 5; } }, "status-enum-asc": function (a, b) { return ((a < b) ? -1 : ((a > b) ? 1 : 0)); }, "status-enum-desc": function (a, b) { return ((a < b) ? 1 : ((a > b) ? -1 : 0)); } });

How can I re-use that function to sort the following select list?

You can put the configuration settings for any library in the main web.config. It's easy!

Connection strings are especially easy. Just add your connection string to the connectionstrings section with the same name it has in the library's app.config, and you're done!

<connectionStrings> <add name="Sitefinity" connectionString="your connection string"/> </connectionStrings>

To add configuration settings, at the top of your web config, find the applicationSettings section, and add your section's info. Note: be sure to set your library's settings access modifier to "Public". You can do this in the Properties ui.

<sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <section name="Your.Assembly" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> </sectionGroup>

Then, add the section under applicationSettings.

This is the simplest example:

TextView yourTextView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); yourTextView = (TextView) findViewById(R.id.your_textview); } @Override protected void onSaveInstanceState(Bundle outState) { outState.putString("YourTextViewTextIdentifier", yourTextView.getText().toString()); super.onSaveInstanceState(outState); } @Override protected void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); yourTextView.setText(savedInstanceState.getString("YourTextViewTextIdentifier")); }

But having an inner class that represents your state will be much nicer when you start saving a lot of objects on orientation change.

Using an inner class it would look like this below. You can imagine as you have more and more state to save the inner class makes it much easier (less messy) to handler.

 private static class State implements Serializable { private static final String STATE = "com.your.package.classname.STATE"; private String yourTextViewText; public State(String yourTextViewText) { this.yourTextViewText = yourTextViewText; } public String getYourTextViewText() { return yourTextViewText; } } @Override protected void onSaveInstanceState(Bundle outState) { State s = new State(yourTextView.getText().toString()); outState.putSerializable(State.STATE, s); super.onSaveInstanceState(outState); } @Override protected void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); State s = (State) savedInstanceState.getSerializable(State.STATE); yourTextView.setText(s.getYourTextViewText()); }

First of all, there's nothing wrong with readable URIs and with users being able to easily explore your API by building URIs by hand. As long as they are not using that to drive the actual API usage, that's not a problem at all, and even encouraged by Roy Fielding himself. Disagreement on that on the basis that URIs must be opaque is a myth. Quoting Fielding himself on that matter:

Maybe I am missing something, but since several people have said that REST implies opaqueness in the URI, my guess is that a legend has somehow begun and I need to put it to rest (no pun intended).

REST does not require that a URI be opaque. The only place where the word opaque occurs in my dissertation is where I complain about the opaqueness of cookies. In fact, RESTful applications are, at all times, encouraged to use human-meaningful, hierarchical identifiers in order to maximize the serendipitous use of the information beyond what is anticipated by the original application.

It is still necessary for the server to construct the URIs and for the client to initially discover those URIs via hypertext responses, either in the normal course of creating the resource or by some form of query that results in a hypertext list. However, once that list is provided, people can and do anticipate the names of other/future resources in that name space, just as I would often directly type URIs into the location bar rather than go through some poorly designed interactive multi-page interface for stock charts.

http://osdir.com/ml/web.services.rest/2003-01/msg00074.html

If you need your client developers to follow the hyperlinks and not build URIs by hand, from my experience I think the best way to do that is to promote it as a cultural change in your work environment. In my case I had a supportive manager, so it was much easier. You should warn them that the URI namespace is under control of the server and the URIs may change anytime. If their clients break because they failed to comply, it's not your responsibility. It also helps a lot to have some sort of workshop or presentation to explain how HATEOAS works and the benefits for everyone. I noticed how a lot of street-REST developers think it's superfluous, until they actually get it.

Now, to address your main question, you shouldn't document the API, you should focus your documentation efforts on your media-type. Quoting Fielding again:

A REST API should spend almost all of its descriptive effort in defining the media type(s) used for representing resources and driving application state, or in defining extended relation names and/or hypertext-enabled mark-up for existing standard media types. Any effort spent describing what methods to use on what URIs of interest should be entirely defined within the scope of the processing rules for a media type (and, in most cases, already defined by existing media types). [Failure here implies that out-of-band information is driving interaction instead of hypertext.]

http://roy.gbiv.com/untangled/2008/rest-apis-must-be-hypertext-driven

That means, you should have custom media-types for your representations, and instead of documenting API endpoints or URIs, you should document those media-types and the operations for the links available in them. For instance, let's say you have an API for a Q&A site like StackOverflow. Instead of having an API documentation telling them that they should POST to the rel:answers link in the representation of a question in order to answer it with their current user, your questions should have a media-type of application/vnd.yourcompany.question+xml and on the documentation for that media-type you say that a POST to a rel:answers http link will answer the question.

I don't know of any existing tools for this, but from my experience, any tool that can be used to generate documentation from abstract models can be used for this.

I don't know how your ecosystem of APIs is, but what works for me is to have a generic documentation with a gentle introduction to REST, addressing some of the misconceptions, and detailed general usage to your patterns, that should apply to any API. After that, each individual server should have its own documentation, focused on the media-type.

I don't like the idea of returning documentation in the text/html representation, because that's supposed to represent the resource itself, but I love the idea of having a rel:doc link pointing to your HTML documentation for that media-type.

8405425 0 Hiding Javascript When Building a Widget

I am building a web widget which will be very easy to integrate. Say http://www.bicycleseller.com/ wants to integrate my widget on his web page. All he has to do is copy and paste the following to the head section of his page:

<script src="http://www.widgetprovider.com/widget.js" type="text/javascript"></script> <script> Widget.create("123456accessKeyOfBicycleSeller").render("myWidget"); </script>

and <div id="myWidget"></div> to anywhere in the body section. The widget will be displayed in that div.

I, as the widget provider, host the widget.js:

var Widget = new function () { this.url = "www.widgetprovider.com/widget.jsp"; this.name = ""; this.parameters = "width=400,height=200,screenX=750,screenY=300,resizable=0"; this.create = function (accessKey) { this.accessKey = accessKey; return this; }; this.render = function (divId) { // make sure the document is fully loaded and place the widget on BicycleSellers page. // when the widget (a jpeg) is clicked, a jsp page I host will popup. window.onload = function () { document.getElementById(divId).innerHTML = '<img src="images/widget-image.jpg" onclick="Widget.display()"/>'; }; return this; }; this.display = function () { // open a popup window that displays a page I host. var popup = window.open(this.url + "?accessKey=" + this.accessKey, this.name, this.parameters); popup.focus(); return this; }; };

So, the BicycleSeller places the widget on his page and when his users click on it, a popup appears that show them content from a page I host. However, each webmaster that wants to embed my widget, has to provide an accessKey, unique to them, because the popup's content will be dependent on that.

My questions are:

1) In this scenario, anyone who goes to bicycleseller.com and views the HTML source can see his accessKey which is hard-coded in the head section. Then they can just navigate to www.widgetprovider.com/widget.jsp?accessKey=123456. I don't want that to happen. What can be done about this? For instance; I was looking at the source of Facebook and they seem to hide everything very well.

2) Is this a good way to go on building a widget? I was thinking of a lightbox rather than a popup window (which might be blocked by a popup blocker - although in this example it does not). Any comments/suggestions welcome.

3) If I try to place to widgets and write Widget.create("key1").render("div1"); Widget.create("key2").render("div2"); two images are generated. But when clicked, both popups display key1 s information. This is because the Widget class in widget.js is singleton. If I don't make it singleton, then I can't place the image's onclick attribute (Widget.display()). What do I do for that?

Looking for help on the three questions. Any help will be greatly appreciated. Thanks.

You can use NSNotificationCenter to make calls between the 2 different views. Add the following code in viewDidLoad method where you have UICollectionView:

NSNotificationCenter.defaultCenter().addObserver(self, selector: "loadList:", name:"load", object: nil)

and then add this method further down in your UIViewContoller:

func loadList(notification: NSNotification){ self.collview.reloadData() }

and from other class when you want to reload collection view:

NSNotificationCenter.defaultCenter().postNotificationName("load", object: nil)

Are you doing a web application? I believe that for non-web applications, you do not need admin rights.

If this is not a web application, maybe it's just a file system permissions issue?

From:

http://msdn.microsoft.com/en-us/library/ms165100.aspx

"User permission requirements for Visual Studio vary depending on the operating system and the Visual Studio version. On Windows Vista, Visual Studio 2008 does not require administrator permissions to perform most tasks, but Visual Studio 2005 must run under administrator permissions to perform tasks correctly. On Windows Server 2003 and earlier, members of the Users group can perform most activities in the integrated development environment (IDE)."

The class defining __slots__ (and not __getstate__) can be either an ancestor class of yours, or a class (or ancestor class) of an attribute or item of yours, directly or indirectly: essentially, the class of any object in the directed graph of references with your object as root, since pickling needs to save the entire graph.

A simple solution to your quandary is to use protocol -1, which means "the best protocol pickle can use"; the default is an ancient ASCII-based protocol which imposes this limitation about __slots__ vs __getstate__. Consider:

>>> class sic(object): ... __slots__ = 'a', 'b' ... >>> import pickle >>> pickle.dumps(sic(), -1) '\x80\x02c__main__\nsic\nq\x00)\x81q\x01.' >>> pickle.dumps(sic()) Traceback (most recent call last): [snip snip] raise TypeError("a class that defines __slots__ without " TypeError: a class that defines __slots__ without defining __getstate__ cannot be pickled >>>

As you see, protocol -1 takes the __slots__ in stride, while the default protocol gives the same exception you saw.

The issues with protocol -1: it produces a binary string/file, rather than an ASCII one like the default protocol; the resulting pickled file would not be loadable by sufficiently ancient versions of Python. Advantages, besides the key one wrt __slots__, include more compact results, and better performance.

If you're forced to use the default protocol, then you'll need to identify exactly which class is giving you trouble and exactly why. We can discuss strategies if this is the case (but if you can possibly use the -1 protocol, that's so much better that it's not worth discussing;-) and simple code inspection looking for the troublesome class/object is proving too complicated (I have in mind some deepcopy-based tricks to get a usable representation of the whole graph, in case you're wondering).

7520819 0 Backslashes disapearing after my vb.net query to Mysql

I'm having some problems, when I do my query from my vb.net program to my mysql DB the data is sent, but its missing some things, let me explain.

My query is pretty simple I'm sending a file path to my DB so that after I can have a php website get the data and make a link with the data from my DB, but when I send my data the results look like this...

 \server_pathappsInst_pcLicences_ProceduresDivers estCheck_list.doc

which should look like

 \\server_path\apps\Inst_pc\Licences_Procedures\Divers\test\Check_list.doc

I don't know if its my code that's not good or my configurations on my mysql server please help...

Here's my code

 'Construct the sql command string cmdString = "INSERT into procedures(Nom, Lien_Nom, Commentaires) VALUES('" & filenameOnly_no_space_no_accent & "', '" & str_Lien_Nom_Procedure & "', '" & str_commentaires_Procedure & "')" ' Create a mysql command Dim cmd As New MySql.Data.MySqlClient.MySqlCommand(cmdString, conn) Try conn.Open() cmd.ExecuteNonQuery() conn.Close() Catch ex As MySqlException MsgBox("Error uppdating invoice: " & ex.Message) Finally conn.Dispose() End Try

Sorry I got a call and could continue my comment so here's the rest :X

Well I guess that would work, but my program never uses the same path since in uploading a file on a server, so this time the document I wanted to upload was this path

 \\Fsque01.sguc.ad\apps\Inst_pc\Licences_Procedures\Divers\test\Check_list.doc

but next time its going to be something else so I can't hard code the paths, I was looking more of a SQL query which that I might not know, since I already thought about searching my string and if it finds a backslash it adds another one, but I feel its not a good way to script the whole thing...

Anyway thanks a lot for your help

Add isEqualTo(:) requirement to JABPanelChangeSubscriber protocol

public protocol JABPanelChangeSubscriber { func isEqualTo(other: JABPanelChangeSubscriber) -> Bool }

Extension to JABPanelChangeSubscriber protocol with Self requirement

extension JABPanelChangeSubscriber where Self: Equatable { func isEqualTo(other: JABPanelChangeSubscriber) -> Bool { guard let other = other as? Self else { return false } return self == other } }

Remember to make objects conform Equatable protocol too

class SomeClass: Equatable {} func == (lhs: SomeClass, rhs: SomeClass) -> Bool { //your code here //you could use `===` operand } struct SomeStruct: Equatable {} func == (lhs: SomeStruct, rhs: SomeStruct) -> Bool { //your code here }

Then find the index

func indexOf(object: JABPanelChangeSubscriber) -> Int? { return subcribers.indexOf({ $0.isEqualTo(object) }) }

If you want to check the existence of an object before adding them to the array

func addSubscriber(subscriber: JABPanelChangeSubscriber) { if !subscribers.contains({ $0.isEqualTo(subscriber) }) { subscribers.append(subscriber) } }

I've found seen screen shaking issues are commonly to do with the order in which you process events, update objects and the camera, before drawing the scene (or the physics engine is causing it :P). With a high framerate you might not notice small imperfections. You might want to add a Sleep/usleep to help expose these issues. For example, if your camera position is based on the camera rotation, but you update the position before processing the mouse events the camera position/rotation can be a frame out of sync.

This is a good reason to process inputs, movement and rendering in very separate stages.

Your lookAt function does look rather complex. lookAt is very useful when you want a camera that looks-at something, but in this case you're after a camera that looks-from a camera position. This is easier to implement by manually constructing the inverse transformations to position the camera object before drawing the sceene. For example, if you want to move left, translate everything else right (thus inverse)...

glLoadIdentity(); glRotatef(camera.rotX, 1.0f, 0.0f, 0.0f); glRotatef(camera.rotY, 0.0f, 1.0f, 0.0f); glRotatef(camera.rotZ, 0.0f, 0.0f, 1.0f); glTranslatef(-camera.posX, -camera.posY, -camera.posZ);

Here are two examples of ways in which you could align a div in the middle:

Using HTML:

<div class="center" style="margin: 0 auto;"></div>

Styling in a separate CSS file:

.center { margin: 0 auto; }

If you are making three columns and want them to resize according to the window width, you set the value of their width to be 33%. Here is an example:

.center { width: 33%; } .left { width: 33%; } .right { width: 33%; }

You have to use TransformFilter. Hope this help.

 TextView textview = (TextView) findViewById(R.id.mytext); textview .setText("WordToBeLinked"); TransformFilter mentionFilter = new TransformFilter() { public final String transformUrl(final Matcher match, String url) { return new String("http://mydomain.com/something"); } }; Pattern pattern = Pattern.compile("."); String scheme = ""; Linkify.addLinks(textview, pattern, scheme, null, mentionFilter);

Since there is no Pattern and scheme in your case, so they are just place holder.

It looks like the login is done successfully, however the user serialization doesn't seem to work as the console.log that I put in it never appears in the console and I cannot access the user id trhough req.user once the user is supposed to be logged in. Did anyone managed to get passport working with sails?

You have to register the Provider in a javax.ws.rs.core.Application. That Application should be registered as a service with a higher service ranking than the default one created by the Amdatu Wink bundle.

The following is a working example.

The Exception Mapper itself:

@Provider public class SecurityExceptionMapper implements ExceptionMapper<SecurityException>{ @Override public Response toResponse(SecurityException arg0) { return Response.status(403).build(); } }

The Application:

import java.util.HashSet; import java.util.Set; import javax.ws.rs.core.Application; import com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider; public class MyApplication extends Application { @Override public Set<Object> getSingletons() { Set<Object> s = new HashSet<Object>(); s.add(new JacksonJsonProvider()); s.add(new SecurityExceptionMapper()); return s; } }

Activator setting the service ranking property.

public class Activator extends DependencyActivatorBase{ @Override public void destroy(BundleContext arg0, DependencyManager arg1) throws Exception { } @Override public void init(BundleContext arg0, DependencyManager dm) throws Exception { Properties props = new Properties(); props.put(Constants.SERVICE_RANKING, 100); dm.add(createComponent().setInterface(Application.class.getName(), props).setImplementation(MyApplication.class)); } }

34711110 0 What is causing "The type or namespace name 'UI' does not exist in the namespace" error?

I am working on a UWP application and I am trying to do something with the values of a SelectedItem in a GridView. So as I usually do with WPF I went into the XAML and Typed my event name in the XAML and let VS create the event in code for me.

<GridView x:Name="DataGrid1" ItemClick="dg_ItemClick"> <!-- Just --> <!-- Some --> <!-- Normal --> <!-- XAML --> </GridView>

and the VS created event looks like this

 private void dg_ItemClick(object sender, Windows.UI.Xaml.Controls.ItemClickEventArgs e) { Biz.Customer cust = e.ClickedItem as Biz.Customer; var messageDialog2 = new MessageDialog(cust.Code, cust.Company); messageDialog2.ShowAsync(); }

Right away I get a red squiggly line under the UI in the Windows.UI.Xaml.Controls part. There is a using at the top of the page to include that and VS wouldn't let add any other UWP references.

I can get the error to go away as I have in other parts of the application by changing the ItemClickEventArgs to RoutedEvenArgs but in this case I really need the ClickedItem as an argument to be passed to the code behind.

I have just talked to someone else getting started with UWP and they said they are having the same issue on other cLick events. So are we both doing something wrong or is there something missing from our application that is needed for the UI to be recognized?

The full error I am getting is this: Error CS0234 The type or namespace name 'UI' does not exist in the namespace 'app name' (are you missing an assembly reference?)

In async Begin* is always followed by End*. See Using an Asynchronous Server Socket. Your accept method should be something like:

try { listener.Bind(localEP); listener.Listen(10); while (true) { allDone.Reset(); Console.WriteLine("Waiting for a connection..."); listener.BeginAccept( new AsyncCallback(SocketListener.acceptCallback), listener ); allDone.WaitOne(); } } catch (Exception e) {

Server, means that an app that listens on specified port/ip. Is usually, always in a listening mode - that's why it is called a server. It can connect and disconnect a client, but is always in listening mode.

This means, when a server disconnects a client - even then - it is in listening mode; meaning it can accept the incoming connections as well.

Though, disconnection request can come from client or can be forcefully applied by server.

The process for a server is:

Bind to socket
Listen
Accept connections

The process for client is:

Connect to the server
Send/receive messages

There are several ways for server to handle the incoming clients, couple, as follows:

Incoming connections are maintained in a list, for instance within a List<TcpClient>.
One way of handling the incoming clients is through threads. For instance, for each incoming client, spawn a thread that would handle the communication between server and client. For instance, checkout this example.

private void ListenForClients() { this.tcpListener.Start(); while (true) { //blocks until a client has connected to the server TcpClient client = this.tcpListener.AcceptTcpClient(); //create a thread to handle communication //with connected client Thread clientThread = new Thread(new ParameterizedThreadStart(HandleClientComm)); clientThread.Start(client); } }

Use single thread and use context switching to manage client communications (TX/RX).

The answer by Howlin is correct, but you shouldn't edit the file in the woocommerce plugin folder. You should copy the specific template file from woocommerce to your own theme directory and edit that file. Removing the link in the copied file will create the same effect as your desired filter.

You should send metadata with your data so the server understands what it needs to do. This means you are defining the protocol to which all clients and servers need to support. For these two different cases (either it is a plain chat message or some command the server needs to execute) you can roll your own protocol. But in software development things always start small and grow large (rapidly).

You might want to look into something like XMPP which is a XML based chat message protocol. http://xmpp.org/xmpp-protocols/

I'm calling tableModel.fireTableCellUpdated(tableRowIndex, tableColumnIndex);

That is wrong. You should never invoke the firXXX methods directly. That is the job of the TableModel to invoke the appropriate event when the data is changed.

I will update the corresponding icon in that cell.

All you need to do is invoke model.setValueAt(...) method to change the Icon and the model will notify the table that data has changed so the table can repaint itself.

examTable.repaint(...)

Again you should not need to manually invoke repaint on the table

But problem comes when I drag and drop the columns from one position to another in Table header.

Not sure why you need special code for this if you follow the advice from above. But if for some reason it is still necessary then you need to look at the convertColumnIndex...(...) methods to make sure you are using the proper index for your column.

List('a','b','a') -> List(('a',2), ('b',1))

So, just mucking around in the console, this works:

val l = List('a', 'b', 'c', 'b', 'c', 'a') val s = l.toSet s.map(i => (i, l.filter(x => x == i).size))

but, shortening by just combining the last 2 lines doesn't?

l.toSet.map(i => (i, l.filter(x => x == i).size))

gives the error "missing parameter type".

Can someone explain why Scala complains about this syntax?

27111520 0 Jstree JSON object

In order to populate Jstree with nodes I want to create a JSON object looks like bellow,

[ { "data": "Basics", "state": "closed", "children": [ { "data": "login", "state": "closed", "children": [ "login", { "data": "results", "state": "closed", "attr": { "id": "node-123" } } ] }, { "data": "Basics", "state": "closed", "children": [ "login", "something", { "data": "results", "state": "closed", "attr": { "id": "node-456" } } ] } ] }, { "data": "All", "state": "closed", "children": [ { "data": "AddCustomer", "state": "closed", "children": [ "login", "Add", { "data": "results", "state": "closed", "attr": { "id": "node-789" } } ] } ] } ]

But I am stuck with creating model object related to this JSON object. Is there any common model object that I can generate above JSON object?

1685921 0 MVP Vs MVVM - why

I was using MVP when I was working with winform. but I moved to MVVM when i started playing with WPF or Silverlight.

The only thing that I noticed is that we don't need to sync with the data between View and ViewModel in MVVM pattern because of powerful binding.

My question are ~

1) Binding (that helps us not to sync View and ViewModel manually) is the only advantage of using MVVM.

2) Is there any other advantage MVVM over MVP? what are the differences?

3) The code below is MVVP pattern or MVVM or both?

interface IView{ void ShowMessage(string message); } class View : IView { public void ShowMessage(string message){ MessageBox.Show(this, message); } } class ViewModel{ private IView view; public ViewModel(IVew view){ this.view = view; } ........ view.ShowMessage("This is a msg"); }

Thanks.

20082189 0 Error message: [__NSCFType _canScrollX]: unrecognized selector

I’m updating an that app usually, but not always, crashes when I swipe from a UIWebView to a UIScrollView. Sometimes it gives the error shown in the title. Most of the time there is no error message. The odd thing is that it does not crash if I use buttons to move to the next screen. The buttons and the swipe gesture recognizer call the same handler.

I’m getting the crash on a first generation iPad running iOS 5.1.1 As far as I know it worked fine on whatever version of iOS 5 that was current when I submitted it in June. I download a copy of the app from the app store and it also crashes on the iPad running iOS 5.1.1.

My workaround is to disable swiping on versions below 6.0.

if ( SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"6.0") ) { UISwipeGestureRecognizer *swipeNext; swipeNext = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeNext)]; [swipeNext setDirection:(UISwipeGestureRecognizerDirectionLeft)]; [self.view addGestureRecognizer:swipeNext]; }

It works fine when I test it in iOS6 and iOS7. I’m not setting _canScrollX. In fact, I can’t even find that method [edit: It’s probably a property, not a method] in the documentation. I’m only setting two properties on the scrollview.

CGFloat quizHeight = ceilf(.9f * _parentView.bounds.size.height - verticalOffset); CGRect quizBounds = CGRectMake(0, verticalOffset, _parentView.bounds.size.width, quizHeight ); _quizView = [[UIScrollView alloc] initWithFrame:quizBounds]; _quizView.delaysContentTouches = YES; _quizView.maximumZoomScale = 1.0f; // Helps with swiping

I don’t think it is a memory issue, since it usually crashes on the first screen. I checked my code for methods that aren’t supported in iOS5 and there aren’t any. But even if there were, I’d think the app would crash all the time, instead of some of the time, and it would give me an error message about the selector causing the problem.

So I’m stumped. Any thoughts?

[Edit{ I tried running with zombies enabled and don’t have any issues. When I use the on-screen button to move from screen to screen, live bytes fluctuates but returns to around 2.4MB. If I swipe, I get a crash and no indication of why in Instruments.

The only difference between successful movement from screen to screen and a crash is the swipe gesture. The button on the screen and the swipe gesture recognizer both call the same method.

This is the crash log.

It's just syntactic sugar -- the compiler inserts the backing field for you. The effect is the same, except that, of course, there's no way for you to access the backing field from your code.

From the page you linked to:

When you declare a property as shown in the following example, the compiler creates a private, anonymous backing field that can only be accessed through the property's get and set accessors.

29205058 0 creating dropdown from php array

I have array like this:

Array ( [0] => Array( [attribute_name] => Brand [attribute_value] => Lee ) [1] => Array( [attribute_name] => Brand [attribute_value] => Levis ) [2] => Array( [attribute_name] => Brand [attribute_value] => Raymond ) [3] => Array( [attribute_name] => Fabric [attribute_value] => Cotton ) [4] => Array( [attribute_name] => Fabric [attribute_value] => Linen ) )

I want to create two drop down from this array one is for Brand which should have three options and another one is for fabric which should have two option.

I can do simply by checking attribute_name is brand or fabric, but this is not static there can be anything instead of brand and fabric.

I've tried so many things but not worked. Please help me in doing this. Thanks in advance.

I don't care what month/year/day is asigned, i only want the time.

That suggests you should be parsing it as a LocalTime, given that that's what the string actually represents. You can then add any LocalDate to it to get a LocalDateTime, if you really want to pretend you've got more information then you have:

import java.time.*; import java.time.format.*; public class Test { public static void main(String args[]) { DateTimeFormatter formatter = DateTimeFormatter.ISO_LOCAL_TIME; LocalTime time = LocalTime.parse("00:00",formatter); LocalDate date = LocalDate.of(2000, 1, 1); LocalDateTime dateTime = date.atTime(time); System.out.println(dateTime); // 2000-01-01T00:00 } }

If you can avoid creating a LocalDateTime at all and just work with the LocalTime, that would be even better.

What was said above is right: You can't prevent an auto-implemented property from being serialized by setting an attribute like [NonSerialized]. It just does not work.

But what does work is the [IgnoreDataMember] attribute in case you are working with an WCF [DataContract]. So

[DataContract] public class MyClass { [DataMember] public string ID { get; set; } [IgnoreDataMember] public string MySecret { get; set; } }

will get serialized under WCF.

Although since WCF is an opt-in technology, you can also just omit the [IgnoreDataMember] and it will work as well. So maybe my comment is a little academical ;-)

How many is too many is really a matter of opinion. However, it's worth being aware how SharedPreferences work in order to get a feel for whether usingSharedPreferences` is the way to go.

As far as I know, there is no hard limit on the size of SharedPreferences, but SharedPreferences are stored in an XML file and when you first access the SharedPreferences the whole file is read and stored in memory so this in itself has an impact on the heap space used by your app and could lead to out of memory errors (partly depending on the size of the data, the available memory and what memory usage the rest of your app requires). Therefore, using SharedPreferences for a large amount of data will often mean you're using more memory than necessary. If you're reading the data from SharedPreferences into another data structure, you'll then have this data in memory twice. Also, XML isn't very efficient in terms of the space used on the filesystem.

I'm not saying it's wrong to use SharedPreferences but there's often a tradeoff between using something that might be more memory efficient (e.g SQLite DB) and give you extra functionality (searching, transaction support, etc.), compared to the simplicity of using SharedPreferences.

It also partly depends what you're storing - e.g. whether you're storing boolean values or long strings makes a huge difference in terms of memory usage. What you're doing with the data might make a difference as to which is the right way to go too. Do you need it to be scalable (e.g. you're storing 100 to 150 values now, but could that increase?).

If I were you, I'd consider how big my data is (i.e. amount of memory used not just number of key value pairs)? Might I need to store more in future? Would the extra functionality of SQLite be useful?

My gut feel based on the limited information you've provided is that I'd probably use SQLite, but I'm basing that on assumptions that scalability might be important and you're storing strings of more than a few characters, and even then I'm sure some people will disagree because "How much is too much" is subjective in this case.

8566124 1 Longest substring (for sequences of triplets)

I am trying to compare strings of the format: AAA-ABC-LAP-ASZ-ASK; basically, triplets of letters separated by dashes.

I'm trying to find between 2 such sequences of arbitrary length (from 1 to 30 triplets) the longest sequence of common triplets.

For example, AAA-BBB-CCC-AAA-DDD-EEE-BBB and BBB-AAA-DDD-EEE-BBB, you can find a sequence of 5 (BBB-AAA-DDD-EEE-BBB, even if CCC is not present in the 2nd sequence).

The dashes should not be considered for comparison; they only serve to separate the triplets.

I'm using Python but just a general algorithm to achieve this should do :)

You pass JSON like that. ArrayList does not accept key and value pair. Then add your keys

You need to set an action Intent Filter .

Something like this

<intent-filter> <action android:name="android.intent.action.SENDTO" /> <action android:name="android.intent.action.SEND" /> </intent-filter>

Check out this link you will get some Idea

It works like this

 Intent intent = new Intent(); intent.setAction(Intent.SEND); startActivity(intent);

You make the same mistake several times. I'll use the first instance an example:

$name = param($name);

You get the value of $name (which you haven't yet defined) and use it to get a param from the HTTP request. Since it isn't defined, you don't get the result you are looking for, so you don't get the submitted data in $name.

Presumably you intended:

$name = param('name');

Update now you have the form you are using:

print qq!<br><form method="get" action="serverside.pl">!; print qq!<input type="submit" value="Confirm Booking" />\n</form><br />!;

You don't have any <input> elements except for the submit button (which doesn't have a name attribute), so there is no data to submit.

6041621 0 UITableView grabbing touch events from subviews

I have a UITableView, which loads UIViews into its cells. These UIViews use the -touchesBegan:withEvent: etc methods, which all work fine & let me implement code to move these subviews around in the table. This all works, until I move my finger vertically & start scrolling the table, then the UIViews stop receiving any touch events. If anyone knows how to get around this I'd be very happy! Many thanks.

One of the alternative ways you can do that (if you actually care much about space) is to store the hash in the binary form. Some details of how to do that may be found here; you'd probably want BINARY(32) for a SHA-256 hash.

Use Rectangle class. There's a method called Intersect or Intersection or something like that.

Say you have one object moving. Make a Rectangle to match the object in position(basically an invisible cover for the object).

Do the same things with another object.

When both are to collide, use the intersection method to check on the collision by using the rectangles.

These might help

27031291 0 Making table rows generated via JQuery act as onClick page redirects

So I am pretty new to JQuery/HTML development of all kinds. Basically I am working on a project where I make an AJAX call that gets a bunch of usernames, dates, etc. regarding Craiglist-like sales that I put into a table format dynamically using JQuery and DOM.

I want to be able to make these elements in the table act as links so that if I click on a certain username, it will take me to their profile. I've tried different suggestions out there but none of them are for tables that are generated with JQuery and I think this is causing problems (but I don't think there is any way around that either). Some snippets of my code are as follows:

function displayCurrentSales(description, seller, date) { var sale = document.createElement("p"); var table = document.getElementById("currentSalesTable"); var row = table.insertRow(-1); var descriptionRow = row.insertCell(0); var userRow = row.insertCell(1); var dateRow = row.insertCell(2); descriptionRow.innerHTML = description; userRow.innerHTML = seller; userRow.onClick = "window.location.href = '../profilePage/index.html?username=' + seller;"; dateRow.innerHTML = date; }

This is my code that I started with except for the userRow.onClick part which I added to try and make it work.

Any help is appreciated, Thanks.

1353675 0 Standard Property Dialog/Browser for ActiveX - Control

I am looking for a property browser/editor for generic activeX controls.

It must work for controls that just expose an IDispatch interface, no proeprty pages of their own.

Best would be something that comes with the OS (like the "All properties" property page VC6 used). It is only for testing, so comfort is not important, modal property sheet or embedded activeX control. The test application is an MFC project.

I thought there was something like that, but the best I can find right now is OleCreatePropertyFrame (which is only the dialog, but not the page i'm after)

Thanks!

34031041 0 VB Downscaling coordinates

I have the need to know when a gdi+ drawn line is clicked on by the mouse.

I have fashioned this function which is used in a loop on all the existing lines and what the function does is:

It makes a buffer of the line's container's size
It makes the whole thing black
It draws the line in green
It gets the pixel at the mouse location
If the pixel is different from black a.k.a green, the line has successfully been clicked and the function should then return true.

This works great, there's no misinterpretations, but I'm afraid that there's a tiny delay (not really noticeable) when my form is in full screen (due to the large buffer).

I'm looking for a way to optimize this, and my first thought is to downscale everything. So what I mean by that is make the buffer like 20x20 and then draw the line in a scaled down version using math. Problem is, I suck at math, so I'm basically asking you how to do this and preferably with an explanation for dummies.

This is the function:

Public Function Contains(ByVal e As Point) As Boolean Dim Width As Integer = Container.Size.Width Dim Height As Integer = Container.Size.Height Dim Buffer As Bitmap = New Bitmap(Width, Height) Using G As Graphics = Graphics.FromImage(Buffer) G.Clear(Color.Black) Dim Start As Point = New Point(ParentNode.Location.X + ParentNode.Size.Width / 2, ParentNode.Location.Y + ParentNode.Size.Height / 2) Dim [End] As Point = New Point(ChildNode.Location.X + ChildNode.Size.Width / 2, ChildNode.Location.Y + ChildNode.Size.Height / 2) Dim Control1 As Point Dim Control2 As Point Control1.X = Start.X + GetAngle(ChildNode.Location, ParentNode.Location, ChildNode.Location.X - ParentNode.Location.X, ChildNode.Location.Y - ParentNode.Location.Y) Control1.Y = Start.Y Control2.X = [End].X Control2.Y = Start.Y G.DrawBezier(New Pen(Color.Green, 4), Start, Control1, Control2, [End]) End Using If Buffer.GetPixel(e.X, e.Y).ToArgb() <> Color.Black.ToArgb() Then Return True End If Return False End Function

This is one of my attempts to make the function use the idea above:

Public Function Contains(ByVal e As Point) As Boolean Dim Width As Integer = 20 Dim Height As Integer = 20 Dim Buffer As Bitmap = New Bitmap(Width, Height) Using G As Graphics = Graphics.FromImage(Buffer) G.Clear(Color.Black) Dim Start As Point = New Point(ParentNode.Location.X + ParentNode.Size.Width / 2, ParentNode.Location.Y + ParentNode.Size.Height / 2) Dim [End] As Point = New Point(ChildNode.Location.X + ChildNode.Size.Width / 2, ChildNode.Location.Y + ChildNode.Size.Height / 2) Dim Control1 As Point Dim Control2 As Point Control1.X = Start.X + GetAngle(ChildNode.Location, ParentNode.Location, ChildNode.Location.X - ParentNode.Location.X, ChildNode.Location.Y - ParentNode.Location.Y) Control1.Y = Start.Y Control2.X = [End].X Control2.Y = Start.Y G.DrawBezier(New Pen(Color.Green, 4), New Point(Start.X / Width, Start.Y / Height), New Point(Control1.X / Width, Control1.Height / Height), New Point(Control2.X / Width, Control2.Y / Height), New Point([End].X / Width, [End].Y / Height)) End Using If Buffer.GetPixel(Width, Height).ToArgb() <> Color.Black.ToArgb() Then Return True End If Return False End Function

i didn't completely understood what you are trying to do... but i think that you want to do is to list all the entities including the date of their last modification.. if that's it, you could use a GROUP BY, and a MAX() function like this

SELECT e.title,e.body,MAX(r.revised) FROM `entities` e JOIN `revisions` r ON r.entity_fk = e.id GROUP BY e.title,e.body

BTW.. i'd change the name of "entity_fk" to "entity_id", its kinda confusing.. at least for me =)

Because of CSS Specificity and because your iPad media query is actually always going to be true (since the screen width on mobiles is always less than 768px). So it will override the rules/selectors you have in your other stylesheets.

You can try reordering you stylesheets the other way around (ie iPad lists first), but i would recommend you specify more explicit media queries to achieve what you want. Have a look at adding a min-device-width clause to your querys.

You can see an advanced example here: http://css-tricks.com/snippets/css/media-queries-for-standard-devices/

4203830 0 jQuery accessing form array

I have a php form and I want to display or hide certain fields dependant on what I select in a drop down. I have code below which works:

I now want to have a multi row block which I am generating using php so I can generate the divs as pupid1, pupid2 etc. and the field $m_perpetrator as an array. I've tried a few ways of accessing the array but can't get anything to work. I thought he following might be along the correct lines for accessing the elements of the array but it does nothing.

if ($("#m_perpetrator[1]").val == "1") { $('div.pupname1').show(); $('div.pupid1').hide(); } else { $('div.pupid1').show(); $('div.pupname1').hide(); }

Added

Here is a snippet of the HTML

<td><select name="m_perpetrator[1]" id="m_perpetrator[1]"> <option value="1">Current</option> <option value="2" selected>Former</option> <option value="3">Parent/Carer</option> </select> </td> <td>Name</td> <td> <div class="pupname1"> <input type="text" size=60 name="m_pupil_name[1]" value="JOHN SMITH"> </div> <div class="pupid1"> <select name="m_pupil_id[1]" onchange="getXtras(this)"> <option value="">Select .....</option>

So basically this is a multi row form and on each row if Current is selected then I want to display pupil_id if anything else is selected then I want to display pupil name. For processing the input I run round the array m_perpetrator[] using php Jim

37977011 0 Can I create a view that needs to calculate its variables using multiple variables from multiple tables?

So I am trying to learn how to work with databases and php but I have run into some trouble concerning whether I can make a view for what i need or if i would just need to get all the variables into a php function and calculate it there.

Here is the database structure i have decided for the project. (The premise is setup a database and webpage for a truck rental company if it helps.)

Vehicles(vehicleId, size, gas) Price(size, price) Customer(customerId, firstname, lastname, streetaddress, city, state, zipcode, email, company) Rental(rentId, customerId, vehicleId, startdate, enddate, tank(0=full positive=number of gallons missing from tank), damage(0=none))

So the view in this example i am trying to create would calculate the total cost for each rental for easy display

total cost is price of specific vehicle size * number of days rented (if returned on same day is 1) + (tank * 5) + damage

The view would also contain the rentalId, and customerId to make it simple to search for total amount spent.

can i do this in mysql or would it need to be done in php?

Expanding parameter packs into varargs is valid.

And there is no harm in forwarding when you want to forward. But taking by const& also communicates something useful.

The values passed to ... will experience "default argument promotions". See http://en.cppreference.com/w/cpp/language/variadic_arguments

None of these care about references.

You can improve your code. You can check that the Ts... are valid types to pass to the printing routine, both by "kind of type" and by actually parsing the formatting string and confirming number (and sometimes type) of arguments. If this fails, you can log an error message instead of crashing.

I'm writing some JAVA assignment I got in school for a few days now, and I ran into something quite weird (well, at least for me it is...).
Since the question has nothing to do with my project in particular, I wrote some code that presents the behaviour I wanted to ask about, so please ignore any problems you might encounter in the following code, that don't relate to this specific issue.
Consider the following class:

package test; import java.util.ArrayList; import java.util.List; public class Car { List<Doors> doors; int numOfDoors; public Car(int numOfDoors) { this.numOfDoors=numOfDoors; } public void prepare() { run(doors); } public void run(List<Doors> listOfDoors) { listOfDoors=new ArrayList<Doors>(numOfDoors); } public List<Doors> getDoors() { return doors; } }

And this:

package test; import java.util.List; public class TestDrive { public static void main(String[] args) { Car car=new Car(5); car.prepare(); List<Doors> listOfDoors=car.getDoors(); if (listOfDoors==null) { System.out.println("This is not the desired behaviour."); } else { System.out.println("This is the desired behaviour."); } } }

I agree, it's kinda stupid and has no point, but again - I wrote it only to satisfy my curiosity.

Now, as you might have guessed, the output is "This is not the desired behaviour.", meaning, the field "doors" holds a null pointer, even though it was assigned with a new object in "run()" method. so my question is why? why is it null?
I mean, I know that creating a local variable - may it be a primitive, an object or a reference to an object - will result in loosing it right when we leave the method's scope, but that is not exactly the case here, since there IS a live reference to that newly created object (doors), then why would JAVA destroy it?
Thanks for anyone who made it through and read the whole post.

When monitoring for beacons transmitting Eddystone-UID, regions should be set up like this:

Identifier eddystoneNamespaceId1 = Identifier.parse("0x00000000000000000001"); Identifier eddystoneNamespaceId2 = Identifier.parse("0x00000000000000000002"); Region eddystoneUidRegion1 = new Region("eddystoneUidRegion1", eddystoneNamespaceId1, null, null); Region eddystoneUidRegion2 = new Region("eddystoneUidRegion1", eddystoneNamespaceId2, null, null); beaconManager.setRangeNotifier(this); beaconManager.startMonitoringBeaconsInRegion(eddystoneUidRegion1); beaconManager.startMonitoringBeaconsInRegion(eddystoneUidRegion2);

In this example, two different regions are defined, each with a 10-byte different Eddystone-UID namespace identifier, and a null Eddystone-UID instance identifier so it will match all beacons with those namespace. The last parameter passed to the Region constructor is also null, because Eddystone-UID beacons only have two identifiers. The code starts monitoring for each of these regions in the last two lines.

The first time any beacon matching the first region is detected (e.g. one with the first namespace identifier), the didEnterRegion callback will be fired, passing a reference to the eddystoneUidRegion1 object. The equivalent callback will also happen if any beacon matching the second region is detected. You can tell which one is detected by examining the contents of the Region object passed to the callback. A different callback exists for didExitRegion when all beacons matching a monitored region disappear.

This is how the Monitoring APIs work. There are also Ranging APIs that give you a callback at approximately 1Hz with a list of all visible beacons that match the Region. Whether you use the Monitoring APIs or Ranging APIs depends on your use case.

I just found out. It's because size of placeholder image didn't match original image.

My solution was simply remove placeholder or resize your placeholder

18735798 0 How to wait in Objective-C, maybe better in blocks?

I know of:

performSelector:afterDelay: and these, but I always have to make an extra method for every delay. In Cocos2d-iphone I use a CCAction for that CCTimeDelay, within a CCSequence. Would be cool if it would also work outside of Cocos2d.

1.

If I want to wait, lets say 1.3 seconds and don't want to split the method in half because of that, what should I do?

2.

I know when I want to wait and don't change the context, the thread will do nothing. So the performSelector methods are good for that.

How to make it happen, that not the whole app waits, userInput should be accepted while waiting. Let's say I want to create an animation of two steps, in between there should be an time interval of 0.8 seconds. To keep it in one method but use multithreading I use blocks then (any other idea appreciated). How to wait inside the block, so the main thread won't get disturbed?

13385693 0 MySQL Select WHERE and removing characters

I have a PHP string that I need to match to a database but in order to match, I first need to make the WHERE part of the statement ignore some characters. For example:

$string = "This is the message. On a few different sentences to make it a bit longer";

Needs to match to

> This is the message. > > On a few different sentences to make it a bit longer

So what I need the WHERE to do is ignore '>','\r\n' and empty lines. I understand I can ignore the first 2 with something like

SELECT * FROM table WHERE REPLACE(REPLACE(fieldtomatch, '>', ''), '\r\n', '') LIKE '%$string%'

But what about the empty lines?

Any help much appreciated!

You use JSON Views

class Views { static class PublicView { } static class StreamA extends PublicView { } static class OtherWay extends PublicView { } } public class Value { @JsonView(Views.PublicView.class) public int value; @JsonView(Views.OtherWay.class) public int value2; @JsonView(Views.StreamA.class) public int value3; } String json = new ObjectMapper() .writerWithView(Views.OtherWay.class) .writeValueAsString(valueInstance);

Note that these are inclusive rather than exclusive; you create a view that includes the fields you want.

33149105 0 How to Change the Style on AvalonEdit CodeCompletion Window?

I'm trying to figure out how to change the style of the AvalonEdit CodeCompletion window. However, I can't figure out the right combination of xaml style target/properties to change it. The main thing I'd like to do is get rid of the border, but maybe some additional changes as well.

Here is the xaml I've tried. None of it is affecting the UI.

 xmlns:ae="clr-namespace:ICSharpCode.AvalonEdit.CodeCompletion;assembly=ICSharpCode.AvalonEdit" <Style TargetType="{x:Type ae:CompletionWindow}"> <Setter Property="WindowStyle" Value="None" /> </Style> <Style TargetType="{x:Type ae:CompletionWindowBase}"> <Setter Property="WindowStyle" Value="None" /> </Style> <Style TargetType="{x:Type ae:CompletionListBox}"> <Setter Property="Background" Value="Red" /> </Style> <Style TargetType="{x:Type ae:CompletionList}"> <Setter Property="Background" Value="Orange" /> </Style>

Problem: Display a Progress Indicator when your application is busy doing some work

Approach:

public class Approach extends ListActivity { ProgressDialog myProgressDialog = null; ListView myList = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); myList = getListView(); myProgressDialog = ProgressDialog.show(getParent(), "Please wait...", "Doing extreme calculations...", true); //Do some calculations myProgressDialog.dismiss(); } }

There are a few challenges (like updating some UI elements). You might want to spawn a different thread to do your calculations if needed.

Also, if you are interested in this, you might be interested in Matt's approach too: android-showing-indeterminate-progress-bar-in-tabhost-activity

Currently you are passing an uninitialized pointer to snprintf, so you get undefined behavior when snprintf writes to it.

I'm trying to code "the 15 game" using jquery in html, See this page. The game is about to get a table of "boxes" in order from 1-15.

My code:

// Insert numbers from 1 to arraysize function insertElements(myArr, arraysize){ for (var i = 1; i < arraysize; i++ ) { myArr.push(i); } } // Check if the two cells is in range function canMove(col, row, empty_row, empty_col){ if((row == empty_row+1) && (col == empty_col) || (row == empty_row-1) && (col == empty_col) || (row == empty_row) && (col == empty_col+1) || (row == empty_row) && (col == empty_col-1)){ return true; } else return false; } // Swap elements in array function swapElements(myArr, indexA, indexB){ // Check bounds if((indexA > myArr.length) || (indexA < 0) || (indexB > myArr.length) || (indexB < 0)) { alert("Out of bounds"); } else{ var temp = myArr[indexA]; myArr[indexA] = myArr[indexB]; myArr[indexB] = temp; } } // Wait for the page to finish loading $(document).ready(function(){ // Create array var myArr = []; var arraysize = 17; var lastelement = arraysize-1; var empty_row; var empty_col; var empty_cell; var col; var row; var nonempty_cell; // Insert the elements insertElements(myArr, arraysize); // Number of shuffles var shuffleNum = 10000; // Shuffle the array for (var i = 0; i < shuffleNum; i++ ) { var f = Math.floor((Math.random()*16)+0); var s = Math.floor((Math.random()*16)+0); swapElements(myArr, f, s); } //printarray(myArr, myArr.length); i = 0; // For each td in the table $(".maincontainer td").each(function() { // Get the radnom value from the array val = myArr[i]; // If the value is the last element // assign this cell to emptycell and add the class empty if(val == lastelement) { empty_cell = $(this); empty_cell.addClass("empty"); empty_row = this.parentNode.rowIndex; empty_col = this.cellIndex; } // Else, assign the value val to its text and add the class nonempty to it else { $(this).text(val); $(this).addClass("nonempty"); } ++i; }); // If one of the nonempty boxes is clicked $(".nonempty").click(function(){ // assign the cell that has been clicked to nonempty cell nonempty_cell = $(this); row = this.parentNode.rowIndex; col = this.cellIndex; // If the cell is in range of the empty cell if(canMove(col, row, empty_row, empty_col)){ // Swap empty cell and the non emptycell clicked var temp = empty_cell; empty_cell = nonempty_cell; nonempty_cell = temp; // Swap coordinates var temprow = row; row = empty_row; empty_row = temprow; var tempcol = col; col = empty_col; empty_col = tempcol; // Get text from the old empty cell var new_value = $(empty_cell).text(); // Assign the value to the nonempty cell text and change class to nonempty $(nonempty_cell).text(new_value); $(nonempty_cell).removeClass("empty").addClass("nonempty"); // "Erase" the textstring and change class to empty $(empty_cell).removeClass("nonempty").addClass("empty"); $(empty_cell).text(""); } else { alert("Cant move!"); } }); $(".empty").click(function(){ alert("Clicked empty cell!"); }); });

<!DOCTYPE html> <html lang='sv'> <head> <meta charset="UTF-8" > <title>The 15 game</title> <style> .maincontainer { width: 35%; border: 10px solid black; } .maincontainer td { width: 100px; height: 100px; text-align: center; font-size: 100px; border: 3px solid black; } .nonempty { background-color: red; } .empty { background-color: #C0C0C0; } .nonempty:hover { border: 3px solid white; } </style> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script> <!-- External javascript with the game --> <script type="text/javascript" src="javascript/15game.js"></script> </head> <body> <!-- Table which is the maincontainer of the 16 boxes --> <table class="maincontainer" > <tr> <td></td> <td></td> <td></td> <td></td> </tr> <tr> <td></td> <td></td> <td></td> <td></td> </tr> <tr> <td></td> <td></td> <td></td> <td></td> </tr> <tr> <td></td> <td></td> <td></td> <td></td> </tr> </table> </body> </html>

The code is kind of working correctly. When I click on a cell that is in range of the empty cell, the two cells are being swapped. The only problem is that the cell that first is assigned the class "empty" seems to keep the class "empty" when I try to replace its class to the class "nonempty".

I'm sorry for any typos, english is not my first language. Thanks for any help!

You don't need to remove newlines from register or press more then one J: with the following mapping it will be "apgVJ:

nnoremap <expr> gV "`[".getregtype(v:register)[0]."`]"

This mapping makes you able to select pasted text just after it was pasted. J on selected region joins all lines in region (unless region has only one line: here J acts like J without a selection, joining current line with next). gV tip can also be used to do substitution: "apgV:s/{pattern}/{replacement}<CR> is more convenient then using "ap:let @a=substitute(@a, '{pattern}', '{replacement}', '{flags}') unless you define some smart mapping.

Another tip is that register a can be cleared using qaq normal mode sequence: qa starts recording a new macro and q immediately stops it leaving empty string in a register where macro is recorded to.

You need to loop through all the deleted records using a cursor. Here is an example of a trigger that does this :

CREATE trigger TR_AspNetUsers_AD on dbo.AspNetUsers for delete as begin -- always do this in triggers set nocount on --trigger specific variables declare @AspNetUsersID int declare crDeleted_AspNetUsers Cursor local fast_forward for select d.AspNetUsersID from deleted d --if there was one or more deletes... open crDeleted_AspNetUsers fetch next from crDeleted_AspNetUsers into @AspNetUsersID while @@FETCH_STATUS = 0 begin --do here whatever you need when deletes have occured... fetch next from crDeleted_AspNetUsers into @AspNetUsersID end close crDeleted_AspNetUsers deallocate crDeleted_AspNetUsers end;

All you need to do is adapt it to your needs.

25938330 0 R: fixed x axis scaling and converting plot() xy arguments to points()

I have a data.frame xy which I am plotting like in the code below.

Is there a way how I could convert my xx and yy in the xy plot() to a points() command so that I could set type='n' and add points() after the segments commands in order to control it better?

xy <- data.frame(NAME=c("NAME1","NAME1","NAME1","NAME2","NAME2","NAME2"),ID=c(87,87,87,199,199,199), X_START_YEAR=c(1984,1986,1984,1899,1909,1924),Y_START_VALUE=c(75,25,-90,-8,-55,-10),X_END_YEAR=c(1986,1994,1999,1909,1924,1927), Y_END_VALUE=c(20,50,-15,-70,-80,-100)) xy NAME ID X_START_YEAR Y_START_VALUE X_END_YEAR Y_END_VALUE 1 NAME1 87 1984 75 1986 20 2 NAME1 87 1986 25 1994 50 3 NAME1 87 1984 -90 1999 -15 4 NAME2 199 1899 -8 1909 -70 5 NAME2 199 1909 -55 1924 -80 6 NAME2 199 1924 -10 1927 -100 ind <- split(xy,xy$ID) for (x in ind){ xx = unlist(x[,grep('X_',colnames(x))]) yy = unlist(x[,grep('Y_',colnames(x))]) fname <- paste0(x[1, 'ID'], '.png') png(fname, width=1679, height=1165, res=150) par(mar=c(6,8,6,5)) plot(xx, yy, main=unique(x[,1]), xlab="Time [Years]", ylab="Value [m]") axis(1, at = seq(1000, 2050, 5), cex.axis=1, labels=FALSE, tcl=-0.3) axis(2, at = seq(-100000, 100000, 500), cex.axis=1, labels=FALSE, tcl=-0.3) x <- x[,-1] segments(x[,2],x[,3],x[,4],x[,5],lwd=2) dev.off() }

If it is possible it would be great if the x axis could be at a fixed range (e.g. from 1940 to 2014) and if values before 1940 are present the x axis should be automatic. The range of the y-axis always differs. How could I incorporate that in my code?

I was looking for quite a bit for a complete working example of a custom wx Python control which subclasses wx.Panel and does custom drawing on itself, and I couldn't find any. Thanks to this (and other) questions, I finally managed to come to a minimal working example - which I'm going to post here, because it does show "drawing to Panel inside of a Frame"; except, unlike the OP, where the Frame does the drawing on the Panel - here the Panel draws on itself (while sitting in the Frame).

The code produces something like this:

... and basically the red rectangle will be redrawn when you resize the window.

I believe if you define user inside UserProfile, then you can access it and will automatically be mapped? It works in my previous projects, I hope it will work with this.

сlass UserProfile { String fio String position String phone String email static belongsTo = [user: User] User userInstance; static constraints = { // some constraints }

Then you can use it

UserProfile.executeQuery("select up.userInstance from UserProfile up")

to this:

$sql = "SELECT id FROM admin WHERE username='$manager' AND password='$password' LIMIT 1"; $result = mysqli_query($conn, $sql);

or this:

$sql = "SELECT id FROM admin WHERE username='$manager' AND password='$password' LIMIT 1"; $result = $conn->query($sql);

($conn is the connection variable change it if it different.) hope this helps out.

Hey, I know this is a bit old, but I've found the EditorialReview part of the response contains the product description. I guess the cravet that Tom talks about still applies, but at least its a way to get to the description without reverting to screen scraping (which is never a good thing!) :)

See this page of the Amazon product API: http://docs.amazonwebservices.com/AWSECommerceService/latest/DG/

EditorialReview Response Group

For each item in the response, the EditorialReview response group returns Amazon's review of the item, which, on the Detail page, is labeled the Product Description.

No nasty screen scraping required! :)

23499514 0 looping over the lines of a file spliiting each line in columns and creating an array of each column

Sorry if my question is too obvious, I´m new in perl.

My code is the following:

open (FILE1, "$ARG[0]") or die @lines1; $i=1; while (<FILE>) { chomp; push (@lines1, $_); my @{columns$1}= split (/\s+/, $lines1[$i]); $i++; }

It gives an error saying

Can´t declare array dereference at the line my @{columns$1}= split (/\s+/, $lines1[$i]);

I wanted to create columns1, columns2, columns3... and each one of them would have the columns of the corresponding line (columns1 of the line 1, columns2 of line 2 and so on...)

Because before I tried to do it this way (below) and every time it was splitting the lines but it was overwriting the @columns1 array so only the last line was saved, at the end I had the values of the 10th line (because it starting counting at 0)

for my $i (0..9) { @columns1 = split (/\s+/, $lines1[$i]); }

PAM - Pluggable Authentication Modules - is a general mechanism which allows you to configure the authentication mechanism used by programs on your system, without requiring recompilation of the relevant programs. So, for example, you can change your system's basic login to use MD5 hashed passwords instead of DES encrypted passwords, without changing (recompiling) the login program.

RADIUS (Remote Authentication Dial-In User Service - but there's a suspicion it is a backronym) is a specific authentication mechanism. There are PAM modules that can authenticate via RADIUS, just as there are other PAM modules that can authenticate with LDAP or Unix password files or ...

Try this:

It was initial created.

let string : String = "danial" let characters = Array(string) println(characters) //["d","a","n","i","a","l"]

String conforms to the SequenceType protocol, and its sequence generator enumerates the characters.

Swift 2, String does no longer conform to SequenceType, but the characters property provides a sequence of the Unicode characters:

let string = "danial" let characters = Array(string.characters) print(characters) //["d","a","n","i","a","l"]

The questions has been answered but I wanted to add a comment about why your first try gives an unexpected result. This is a good example of R's vector recycling.

I'm guessing you got

 year value 6 2008 4 13 2011 8

Why has R done this? What happens is R recycles the vector c("2008", "2009", "2010", "2011") like the below.

year value compare 2006 3 2008 2007 4 2009 2007 3 2010 2008 5 2011 2008 4 2008 2008 4 2009 2009 5 2010 2009 9 2011 2010 2 2008 2010 8 2009 2011 3 2010 2011 8 2011 2011 7 2008 2012 3 2009 2013 4 2010 2012 6 2011

Do you see what's about to happen? When you run

df<-df[df$year == c("2008", "2009", "2010", "2011"),]

it will return the rows where the year column and the compare column are equal. You didn't get a warning because (by chance) your comparison vector was a divisor of the number of rows, so R thought it was doing the right thing.

You must treat all data coming from the client as suspect. This includes the URL. You should check that this client is indeed authenticated and that he is authorized to perform whatever action is indicated (by the URL, post data, etc). This is true even if you are only displaying data, not changing it.

It is not important if the record id is easily seen or modifiable in the URL. What matters is what can be done with it. Unless the id itself imparts some information (which would be surprising), there is no need hide it or obfuscate it. Just make sure you only respond to authenticated and authorized requests.

You should disable gravity for the islands' rigidbody, first of all. That way, they will float, but things like inertia will still apply.

If you want your character to pull the islands to himself when grabbing them with a rope, you could use Rigidbody.AddForce(Vector3 vec3) and pass the vector opposite to the direction the rope is aimed at as a parameter (you should use Vector3.Reflect() to do that.)

This will get you started, but there are more ways to improve the effect, such as making the islands gradually slow down after pulling them. I'd suggest multiplying the island's velocity by a fraction of 1, in that case, but there are other ways to do it.

Trying to do something simple Data Compare in SSDT but proving a bit hard.

In one database, I have two tables I want to compare.

These tables have the same schema, just different table names. And I just want to see if this tool will give me a nice way to compare the data in both.

I.e.

tblOutput tblOutput_210314

But this picking of two tables to compare against each other in a single database I can't see how to achieve.

Seems like you can only pick a table name which exists in both source and target databases. Since my source and target database is the same, I am basically comparing my table to itself ?

Anyone know of a way to achieve this with Data Compare ?

Server code:

ServerSocket server = new ServerSocket(6780); Socket clientSocket = server.accept(); ObjectInputStream fromClient= new ObjectInputStream(clientSocket.getInputStream()); ObjectOutputStream toClient = new ObjectOutputStream(clientSocket.getOutputStream());

Client code:

Socket nodeSocket = new Socket(ServerIP, 6780); ObjectInputStream fromServer = new ObjectInputStream(nodeSocket.getInputStream()); ObjectOutputStream toServer = new ObjectOutputStream(nodeSocket.getOutputStream()); toServer.writeObject(this);

When a client connects, server listens and accepts client connection. But when I try to write my class object to the server, "toServer.writeObject(this);" it throws

Peer is my class name.

I tried to find out the cause of this exception, it says that object that needs to be written must be serializable. I also tried to implement Serializable interface from Peer class. But that doesnt help.

Can anyone suggest?

You probably shouldn't be calling glLookAt at all. You sure don't want every object drawn in the middle of the screen. Do you have a problem with the objects changing the modelview matrix and not putting it back? Use glPushMatrix and glPopMatrix instead of repeating the look-at calculation.

The point of lazy init is to defer allocating resources since you don't know when or if you need them.

In your case, this doesn't really make sense: As soon as the image is uploaded, the server will need the thumbnail -- the user wants to see the new image immediately, right? Therefore deferring the creation of the thumbnail has no positive ROI.

Given that you're using the system Perl (and, from a comment, it seems you have root) then the easiest approach is probably to install the package that is pre-built for your Linux distribution.

For a Debian/Ubuntu-based system:

$ sudo apt-get install libtext-csv-perl

For a RedHat/Centos/Fedora-based system:

$ sudo yum install perl-Text-CSV

When Ruby loads the file containing your module B and reaches the acts_as_taggable line, it will try to execute the acts_as_taggable class method of ClassMethods (which doesn't exist because it is actually a class method of ActiveRecord::Base).

You can use the included method to call acts_as_taggable when your module is included though. included is passed the class the module is being included in, so the following will work:

module B def self.included(base) base.acts_as_taggable # ... end # ... end

I run a lot of rails production servers this way and all other debian ruby packages are not broken because they relay on /usr/bin/ruby1.8 binary.

The current working directory in ST can be opened in the Finder by right-clicking anywhere in an open file and selecting "Reveal in Finder".

At any rate, the concept of a 'current working directory' is meaningful in ST only in the context of a project which itself is a folder and all the files in it (except the ones filtered out by the project file). That would preclude the possibility of changing the working directory straight away, I should think

It's a bit complicated to make only the first item in the collection required. I suggest you creating a separate property for that and mark it as required:

ViewModel

public class MyViewModel { [Required] public string RequiredName { get; set; } public List<string> SubSiteNames { get; set; } }

View

<label>Name </label> @Html.TextBoxFor(m => m.RequiredName) @Html.ValidationMessageFor(m => m.RequiredName) @for (int i = 1; i <= 3; i++) { <label>Name </label> @Html.TextBoxFor(m => m.SubSiteNames[i - 1]) }

Then just remove the first item from the SubSiteNames list and set it to the RequiredName.

You could do this, and you can do it in several ways.

1) (simple) copy the file to your server, and rename it. Point your download links to this copy.
2) (harder) Create a stub php file, called , read the file from the remote server within php, and stream the content to the script output. This will need you to set appropriate headers, etc. as well as setting up your webserver to parse through PHP.

Seriously, I'd go with option 1. (assumes you have a legal right to serve the content, etc.)

10311456 0 Multiple CI application in a sub-domain

I am new to Apache environment. Preferably I do not want .htaccess file, but I think I have not choice. My application runs without problem in my notebook which is windows environment using WAMPSERVER. But when I deploy to hosting server which uses Apache, I face some problems. I am not sure the following structure is correct for CodeIgniter application. Following is the directory structure in hosting server...

httodocs/ /survey /admin /config <-- $route['default_controller'] = "admin"; /controllers /models /views /... /statistic /config <-- $route['default_controller'] = "statistic"; /controllers /models /views /... /mySurvey /config <-- $route['default_controller'] = "mySurvey"; /controllers /models /views /... /css /images /scripts /system /... /index.php <-- $application_folder = 'mySurvey'; /admin.php <-- $application_folder = 'admin'; /Statistic.php <-- $application_folder = 'statistic';

What I did was just duplicate the Application folder and rename to admin, statistic and mySurvey respectively, I set the default controller as stated above.

all application base_url() = 'http://survey.myhost.com' which is a sub domain under myhost.com

The root index.php is actually CI application environment which allow user to go to mySurvey application by default, when they enter "http://survey.myhost.com".

From the first page on, when I access http://survey.myhost.com/index.php/mySurvey/index/0 I got error:

`The specified CGI application misbehaved by not retruning a complete set of HTTP headers.`

The same message shows when I access http://survey.myhost.com/admin.php/admin/login or http://survey.myhost.com/statistic.php?statistic/chart/1 (note that I also do use query string for my application)

Obviously, these have to do with the route. I do not have any .htaccess file at the server because WAMP does not need it, Appreciate if anyone can advice where can I put the .htaccess file and what is the correct mod-rewrite for the structure above and is this structure appropriate.

Regards,

KK Gian

28477244 0 Why does Ansible fail to execute this simple shell script?

I came across a very strange problem with Ansible (1.8.2) that boils down to executing this simple command in a shell script:

#!/bin/sh # transform a String into lowercase chars: echo "TeSt" | tr [:upper:] [:lower:]

When I log into the remote Solaris machine, this script seems to work no matter in which shell I am (e.g., /bin/sh, /bin/bash):

# ./test.sh test

Also when I execute this script using a remote ssh command, it works:

# ssh root@<remote-host> '/tmp/test.sh' test

However, when I execute the same script with the Ansible command or shell modules, I get a "Bad String" error no matter what shell I specify:

- shell: executable=/bin/sh /tmp/test.sh [FATAL stderr: Bad string] - shell: executable=/bin/bash /tmp/test.sh [FATAL stderr: Bad string] - command: /tmp/test.sh [FATAL stderr: Bad string]

It took me ages to figure out that it works with the raw module:

- raw: executable=/bin/sh /tmp/test.sh [OK]

Does anyone have a clue why the shell and command modules produce this error?

Some more info about the remote host on which the script fails:

SunOS 5.10 Generic_150401-18 i86pc i386 i86pc
All shells (/bin/sh, /bin/bash, /bin/ksh) are GNU bash, version 4.1.2(1)-release (x86_64-redhat-linux-gnu)
Python 2.6.6

The locale differs! When I log in or execute a remote ssh command, the locale looks like this:

LANG= LC_CTYPE="C" LC_NUMERIC="C" LC_TIME="C" LC_COLLATE="C" LC_MONETARY="C" LC_MESSAGES="C" LC_ALL=

However, with Ansible, I get this:

LANG=en_US.UTF-8 LC_CTYPE=en_US.UTF-8 LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_ALL=

Using dp is the right way. It wont be a constant size cuz AOS will scale dps using multiplier according to screen density. (btw dip==dp they are absolutely the same) so dps are density independent. However scaling is not enough usually. So you need to create separate resources for different screens and I might say that supporting multiple screens is a really very big pain in da @$$. Seems like the only one good and proper way is to use OpenGL...

Your ItemsSource is a simple binding to a collection of [something] that will fill out the combolist, here's a quick sample:

public class MyDataSource { public IEnumerable<string> ComboItems { get { return new string[] { "Test 1", "Test 2" }; } } } <ComboBox Height="23" Name="status" IsReadOnly="False" ItemsSource="{Binding Path=ComboItems}" Width="120"> </ComboBox>

That's not a complete sample, but it gives you the idea.

It's also worth noting that you don't have to use the ItemsSource property, this is also acceptable:

<ComboBox Height="23" Name="status" IsReadOnly="False" Width="120"> <ComboBox.Items> <ComboBoxItem>Test 1</ComboBoxItem> <ComboBoxItem>Test 2</ComboBoxItem> </ComboBox.Items> </ComboBox>

My personal favorite would be to generate a CSV file (using a 4.5 lines script) and load it into your SQL DB using BULK INSERT. This will also allow better customization of the data as sometimes is needed (e.g. when writing tests).

24820584 0

You can simplify this a little bit.

function searchBox(inputVal) { var regExp = new RegExp(inputVal, 'i'); $('#boxdata').find('tr').removeClass('red').filter(function() { return $(this).find('td').filter(function() { return regExp.test( $(this).text() ); }).length && $.trim(inputVal).length; }).addClass('red'); }

So remove the red class from all <tr>'s first, then filter them, test the text of each <td>, if it matches, return the <tr> and then add the class red again.

Here's a fiddle

As for changing from a table to div, the jQuery would depend on how you structure your markup, but the principle would remain the same.

I am generating my first bot working with node.js and heroku but finding some difficulties to understand the persistent menu functionalities.

Question 1) How do can I attach event as callbacks?

function persistentMenu(sender){ request({ url: 'https://graph.facebook.com/v2.6/me/thread_settings', qs: {access_token:token}, method: 'POST', json:{ setting_type : "call_to_actions", thread_state : "existing_thread", call_to_actions:[ { type:"postback", title:"FAQ", payload:"DEVELOPER_DEFINED_PAYLOAD_FOR_HELP" }, { type:"postback", title:"I Prodotti in offerta", payload:"DEVELOPER_DEFINED_PAYLOAD_FOR_HELP" }, { type:"web_url", title:"View Website", url:"https://google.com/" } ] } }, function(error, response, body) { console.log(response) if (error) { console.log('Error sending messages: ', error) } else if (response.body.error) { console.log('Error: ', response.body.error) } })

}

Question 2) The only way I have found for empty the persistent menu and generating a new one is with a delete request via terminal ("as Facebook documented")m is there a possibily to clear inserting a refresh function on my app.js file?

Here is a solution i found with your markup.

Used CSS to beautify it.

Jquery:
What did you do?
when .menu_link is hovered i find what index it has.
The index finds if its the first child or second etc.
When we have this magic index number var nthNumber
we can use it to find its corresponding .submenu_panel (I'm guessing here since i cant see all your code) and hide or show this panel

Eg. when we hover the first .menu_link,
we will show the first .submenu_panel
And we do the same for the second and third etc.

$(".menu_link, .submenu_panel").hover(function() { //Hover inn function var nthNumber = $(this).index() + 1; $("[id$=Submenu]").show(); $("[id$=Submenu] .submenu_panel:nth-of-type(" + nthNumber + ")").show(); }, function() { //Hover out function $("[id$=Submenu]").hide(); var nthNumber = $(this).index() + 1; $("[id$=Submenu] .submenu_panel:nth-of-type(" + nthNumber + ")").hide(); });

#menu [id$=Menu] { border: 2px solid #2980b9; border-radius: 5px; background-color: #3498db; } #menu [id$=Menu] .menu_link { padding: 10px 10px; display: inline-block; font-size: 1.2em; } #menu [id$=Menu] .menu_link:hover { background-color: #45a9ec; //border: 2px solid #2980b9; border-radius: 2px; cursor: pointer; //Visual only (REMOVE)! } #menu [id$=Submenu] { display: none; } #menu [id$=Submenu] .submenu_panel { display: none; background-color: #45a9ec; border: 2px solid #2980b9; border-top: none; border-bottom-right-radius: 2px; border-bottom-left-radius: 2px; } #menu [id$=Submenu] .submenu_panel .submenu_link { position: relative; display: block; text-indent: 15px; font-size: 1.1em; padding: 4px 0px; border-bottom: 1px solid #2980b9; } #menu [id$=Submenu] .submenu_panel .submenu_link:hover { background-color: #56bafd; cursor: pointer; //ONLY FOR VISUAL(REMOVE)! } #menu [id$=Submenu] .submenu_panel .submenu_link:first-child { border-top: 1px solid #2980b9; margin-top: -5px; padding-top: 5px; }

One possible check you could make to determine if there was enough space, would be to check how much area the current set of rectangels are taking up. If the amount of area left over is less than the area of the new rectangle then you can immediately give up and bail out. I don't know what information you have available to you, or whether the rectangles are being laid down in a regular pattern but if so you may be able to vary the check to see if there is obviously not enough space available.

This may not be the most appropriate method for you, but it was the first thing that popped into my head!

This approach seems a little smelly in that you have deployment concerns leaking into your service contracts and implementation. Given that REST does not expose metadata anyway I don't see a lot of benefit in the different interfaces.

I would have thought a behavior or ServiceAuthorizationManager, which examined the message version and disallowed access for REST requests would be a cleaner solution. That way you could have a single service implementation for a single contract and push protocol issues back to where they belong: deployment and configuration.

The observer is notified when an observed key path changes it's value. The ´change` dictionary contains information related to how the observed key path has changed. This dictionary is only filled with the values according to the options that you provide when setting

NSKeyValueObservingOptionNew - Specifies that you want to have access to the new value that the key path changed into.
NSKeyValueObservingOptionOld - Specifies that you want to have access to the old value that the key path changed from.

If specified to be sent these old and/or new values are accessible from the change dictionary using these keys:

NSKeyValueChangeNewKey - To access the new value.
NSKeyValueChangeOldKey - To access the old/previous value.

Your program can't know that because it simply doesn't know when it's not running. And when it IS running, it simply uses 100% of the CPU. In this case, precentages make sense only as relative measurements, but you haven't specified relative to WHAT.

38415962 0 webgl - how do i declare a float variable

super simple question: how do i properly declare a float variable in webgl?

Background:

I'm playing with this codepen: http://codepen.io/jlfwong/pen/Wxjkxv

the point of this codepen is to allow you set the color of each pixel in a shader based on a render function.

I get the basics and I got things working pretty well, but then I tried to get "fancy".

I'm focussing on this section:

var fragmentShader = compileShader(' \n\ void main(){ \n\ gl_FragColor = vec4(step(25.0, mod(gl_FragCoord.x, 50.0)), \n\ step(25.0, mod(gl_FragCoord.x, 50.0)), \n\ step(25.0, mod(gl_FragCoord.x, 50.0)), \n\ 1.0); \n\ } \n\ ', context.FRAGMENT_SHADER);

All I want to do is save step(25.0, mod(gl_FragCoord.x, 50.0)) off to a variable so i tried this:

var fragmentShader = compileShader(' \n\ void main(){ \n\ float x_thing = step(25.0, mod(gl_FragCoord.x, 50.0)); \n\ \n\ gl_FragColor = vec4(x_thing, x_thing, x_thing, 1.0); \n\ } \n\ ', context.FRAGMENT_SHADER);

This doesn't work because it seems to be missing a precision declaration for float. here is the error:

uncaught exception: Shader compile failed with: ERROR: 0:3: '' : No precision specified for (float)

I have tried a few things to remedy this:

precision float x_thing = step(25.0, mod(gl_FragCoord.x, 50.0));
precision highp float x_thing = step(25.0, mod(gl_FragCoord.x, 50.0));
precision highp float; float x_thing = step(25.0, mod(gl_FragCoord.x, 50.0));

Also i've been googling and fiddling with this for a while and I'm just annoyed with having issues declaring a variable :P

TL;DR

how do i properly declare a float variable in webgl? / what am i doing wrong?

If you want do do it in ajax, you should put your form inside an iframe, so when you upload the image, only a small part of the page (the form) is sent to your server.

After that, you can use upload.php response to get the name and path of uploaded image, and then you can just change the src of the img tag.

The text rendering code is probably disabling the depth test and your cube drawing code doesn't (re-)enable it.

The line

gloo.set_state(clear_color=(0.30, 0.30, 0.35, 1.00), depth_test=True)

does enable depth testing, but its set only in the constructor. Here's an important rule (speak with me): There is no "initialization" in OpenGL. There's just state, which must be set when needed, right before it's needed to what it is needed to be. Add this

right before the cube triangle drawing code, i.e.

def on_draw(self, event): gloo.clear(color=True, depth=True) self.testText.draw(self.tr_sys) #draw text

 gloo.set_state(depth_test=True) self.program.draw('triangles', self.indices) #draw the cube

import sqlite3, operator reference = [[1, 0, 0], [2, 0, 10], [3, 0, 20], [4, 0, 30], [5, 0, 40]] temperature = [[0, 0, 100], [0, 10, 110], [0, 20, 120], [0, 30, 130], [0, 40, 140]]

A couple of helpers - I like using these because it makes subsequent code readable.

reference_coord = operator.itemgetter(1,2) ref = operator.itemgetter(0) temperature_coord = operator.itemgetter(0,1) temp = operator.itemgetter(2)

Create a database (in memory)

con = sqlite3.connect(":memory:")

Two ways to approach this, preserve all the information in separate tables or create a single table with only the data you want

One table for each list

con.execute("create table reference(coordinate TEXT PRIMARY KEY, reference INTEGER)") con.execute("create table temperature(coordinate TEXT PRIMARY KEY, temperature INTEGER)") # fill the tables parameters = [(str(reference_coord(item)), ref(item)) for item in reference] con.executemany("INSERT INTO reference(coordinate, reference) VALUES (?, ?)", parameters) parameters = [(str(temperature_coord(item)), temp(item)) for item in temperature] con.executemany("INSERT INTO temperature(coordinate, temperature) VALUES (?, ?)", parameters )

Query the two tables for the data you need

cursor = con.execute('SELECT reference.reference, temperature.temperature FROM reference, temperature WHERE reference.coordinate = temperature.coordinate') print(cursor.fetchall())

Table that combines the data in the two lists

con.execute("create table data(coordinate TEXT PRIMARY KEY, reference INTEGER, temperature INTEGER)")

Build the table with only the data you care about

parameters = [(str(reference_coord(item)), ref(item)) for item in reference] con.executemany("INSERT INTO data(coordinate, reference) VALUES (?, ?)", parameters) parameters = [(temp(item), str(temperature_coord(item))) for item in temperature] con.executemany("UPDATE data SET temperature=? WHERE coordinate=?", parameters)

Simple query because the table only has what you want

cursor2 = con.execute('SELECT reference, temperature FROM data') print(cursor2.fetchall()) con.close()

Result:

>>> [(1, 100), (2, 110), (3, 120), (4, 130), (5, 140)] [(1, 100), (2, 110), (3, 120), (4, 130), (5, 140)] >>>

Once you get your data into a database it is fairly easy to extract information from it, and the database can be persisted if a file db is used instead of a db in memory.

If an external library is acceptable, pandas has similar functionality and is an awesome package.

I have defined my app as home screen but I have to change the home screen during my app execution. I know it is not possible to change the home screen, it is only possible to launch the home screen selector. How could I launch the home screen selector when I need to do it?

I'm using:

PackageManager pm = getPackageManager(); pm.clearPackagePreferredActivities("com.dm.prado");

I have two problems:

The selector is only showed when I press home button, I want to show it when I want.

The selector is never showed again when I Selecthome screen first time

39414088 0 Is stack memory only for pointers and heap for objects?

Firstly, I'm currently working in C# and I've been reading up on memory management. So far, I've read through some great answers on stack overflow explaining the difference between stack memory and the managed heap memory. The majority of the answers state that by declaring:
int x = 5, you're allocating enough memory for the type of x within the stack memory.

I understand how this works as well as the scope of it, however when I read the explanation of heap memory, it confused me.

If you're saying int x = 5, since int is an alias of System.Int32, wouldn't x technically be a pointer to a new instance of the System.Int32 struct? And if so, wouldn't it then be stored in the heap memory since that's used for instance objects.

In this tutorial, it states (for the line class1 cls1 = new class1()):

... creates a pointer on the stack and the actual object is stored in a different type of memory location called ‘Heap’.

By this logic, isn't everything stored on the heap and only pointers stored on the stack? Examples being new instances of System.String, System.Int64, System.Boolean, System.Decimal etc.

I thought I understood it, however clearly I don't, so I would appreciate someone explaining whether the stack is only for pointers or which part I've misinterpreted. Thanks in advance.

Without seeing your stack trace, I'm only guessing, but:

From the line you say is the error, it means that div is null, which would indicate that the previous line is the culprit, which would mean that your doc has no Element with an Id of eventTTL.

Try ensuring that your doc is valid, and the it actually has a eventTTL.

6892968 0 Insert data from custom PHP function into MySQL database

I'm having problems inserting a particular line of code into my MySQL database. It inserts three rows just fine, but the "html_href" row isn't going in for whatever reason. Here is my code:

 function html_path() { $title = strtolower($_POST['title']); // convert title to lower case $filename = str_replace(" ", "-", $title); // replace spaces with dashes $html_href = $filename . ".html"; // add the extension }

And my MySQL query code:

 $query = "INSERT INTO work (title, logline, html_href, synopsis) VALUES"; $query .= "('".mysql_real_escape_string($_POST['title'])."',"; $query .= "'".mysql_real_escape_string($_POST['logline'])."',"; $query .= "'".html_path()."',"; $query .= "'".mysql_real_escape_string($_POST['synopsis'])."')"; $result = mysql_query($query);

The title, logline, and synopsis values go in just fine, but the html_href() function inserts a blank row.

6990135 0 What other hidden variables (pre-defined using macros) do I have access to in g++?

note: I am using g++ version 4.3.4

So I was learning about assert statements and came across a homebrew assert macro that uses that variables __LINE__ and __FILE__ which (cleverly) give the line number and the file name from where they were called -- in this case, from where the assertation failed. These are epic pieces of information to have!

I was able to infer that the variable __FUNCTION__ will give you the function name that you are inside of... amazing!! However, when assert.h is at work, you also get the arguments to the function (i.e. function: int main(int, char**) and all I can do currently is get the function name...

Generally speaking, where can I learn more about these wonderful hidden variables and get a complete list of all of them?

p.s. I guess I understand now why you aren't supposed to use variable names starting with __

The library itself compiles without any problem, but when I try and compile a binary and link it against it I get the following error

You're probably believe that you're passing in the library too early so the linker has already processed it before it gets around to needing that definition.

2547979 0 jQuery Validation plugin results in empty AJAX POST

I have tried to solve this issue for at couple of days with no luck. I have a form, where I use the validation plugin, and when I try to submit it, it submits empty vars. Now, if I remove the validation, everything works fine. Here is my implementation:

$(document).ready(function(){ $("#myForm").validate({ rules: { field1: { required: true, minlength: 5 }, field2: { required: true, minlength: 10 } }, messages: { field1: "this is required", field2: "this is required", }, errorLabelContainer: $("#validate_msg"), invalidHandler: function(e, validator) { var errors = validator.numberOfInvalids(); if (errors) { $("#validate_div").show(); } }, onkeyup: false, success: false, submitHandler: function(form) { doAjaxPost(form); } }); }); function doAjaxPost(form) { // do some stuff $(form).ajaxSubmit(); return false; }

As I wrote this does not work when I have my validation, BUT if I remove that, and just add an

onsubmit="doAjaxPost(this.form); return false";

to my HTML form, it works - any clue???

Rather than compressing images, you'd better compress video streams. This is how video codec achieve high compression : by exploiting similarities into consecutives images in the stream.

If you compress your images one by one, you loose this performance advantage, and it makes a huge difference in bandwidth.

I looked at the other questions of sending HTTP Post using Jersey and all I could find was a way to only send a key\value pairs as parameters and not complex string types like above.

40256658 0 Getting an object array from an AngularJS 2 service

I am new to AngularJS 2 (and Javascript for that matter). I've written an AngularJS 2 service which returns an array of users. The data is retrieved from an HTTP call which returns the data in JSON format. When logging the JSON data returned from the HTTP call, I can see that this call is successful and the correct data is returned. I have a component which calls the service to get the users and an HTML page which displays the users. I cannot get the data from the service to the component. I suspect I am using the Observable incorrectly. Maybe I'm using subscribe incorrectly as well. If I comment out the getUsers call in the ngInit function and uncomment the getUsersMock call, everything works fine and I see the data displayed in the listbox in the HTML page. I'd like to convert the JSON data to an array or list of Users in the service, rather then returning JSON from the service and having the component convert it.

Data returned from HTTP call to get users:

[ { "firstName": "Jane", "lastName": "Doe" }, { "firstName": "John", "lastName": "Doe" } ]

user.ts

export class User { firstName: string; lastName: string; }

user-service.ts

... @Injectable export class UserService { private USERS: User[] = [ { firstName: 'Jane', lastName: 'Doe' }, { firstName: 'John', lastName: 'Doe' } ]; constructor (private http: Http) {} getUsersMock(): User[] { return this.USERS; } getUsers(): Observable<User[]> { return Observable.create(observer => { this.http.get('http://users.org').map(response => response.json(); }) } ...

user.component.ts

... export class UserComponent implements OnInit { users: User[] = {}; constructor(private userService: UserService) {} ngOnInit(): void { this.getUsers(); //this.getUsersMock(); } getUsers(): void { var userObservable = this.userService.getUsers(); this.userObservable.subscribe(users => { this.users = users }); } getUsersMock(): void { this.users = this.userService.getUsersMock(); } } ...

user.component.html

... <select disabled="disabled" name="Users" size="20"> <option *ngFor="let user of users"> {{user.firstName}}, {{user.lastName}} </option> </select> ...

!!! UPDATE !!!

I had been reading the "heroes" tutorial, but wasn't working for me so I went off and tried other things. I've re-implemented my code the way the heroes tutorial describes. However, when I log the value of this.users, it reports undefined.

Here is my revised user-service.ts

... @Injectable export class UserService { private USERS: User[] = [ { firstName: 'Jane', lastName: 'Doe' }, { firstName: 'John', lastName: 'Doe' } ]; constructor (private http: Http) {} getUsersMock(): User[] { return this.USERS; } getUsers(): Promise<User[]> { return this.http.get('http://users.org') .toPromise() .then(response => response.json().data as User[]) .catch(this.handleError); } ...

Here is my revised user.component.ts

... export class UserComponent implements OnInit { users: User[] = {}; constructor(private userService: UserService) {} ngOnInit(): void { this.getUsers(); //this.getUsersMock(); } getUsers(): void { this.userService.getUsers() .then(users => this.users = users); console.log('this.users=' + this.users); // logs undefined } getUsersMock(): void { this.users = this.userService.getUsersMock(); } } ...

!!!!!!!!!! FINAL WORKING SOLUTION !!!!!!!!!! This is all the files for the final working solution:

user.ts

export class User { public firstName: string; }

user.service.ts

import { Injectable } from '@angular/core'; import { Http, Response } from '@angular/http'; import { Observable } from 'rxjs/Observable'; import 'rxjs/add/operator/catch'; import 'rxjs/add/operator/map'; import { User } from './user'; @Injectable() export class UserService { // Returns this JSON data: // [{"firstName":"Jane"},{"firstName":"John"}] private URL = 'http://users.org'; constructor (private http: Http) {} getUsers(): Observable<User[]> { return this.http.get(this.URL) .map((response:Response) => response.json()) .catch((error:any) => Observable.throw(error.json().error || 'Server error')); } }

The #{...} are markers for spel interpreter in xml context.

I don't undestand : ${#code}/${#value}. Good is #{code/value}, as I understand things, if code and value are id.

So, if you want a spel expression without interpret it, put string code/value in xml.

I hope this is a relatively easy problem although I have spent hours websearching and using T&E to no avail. Hopefully someone can help ;o)

I have an excel module that shows a UserForm to get some input data before doing a lot of processing. At the bottom of the userform are a couple of command buttons labeled "OK" and Cancel". I need to be able to have the user change option buttons then click on OK or Cancel to exit, where my module will continue the process based on whether or not "Cancel" was pressed.

Based on the True or False from the Cancel, I can drive the rest of the procedure.

There appear to be a number of ways to achieve this but many seem a bit out of date or overly complicated. As of Feb 1 2010 all I did to get PHP and Apache2 working on Gentoo was to install Apache and PHP like this:

bash$ emerge apache
Followed the instructions for the particular extensions I wanted at this list at the Gentoo site
- NOTE: this is the important one to get Apache and PHP working together:
  - bash$ echo "dev-lang/php apache2" >> /etc/portage/package.use
- Another common PHP extension:
  - bash$ echo "dev-lang/php mysql" >> /etc/portage/package.use
- And so on.
Then just run bash$ emerge dev-lang/php and restart Apache with the /etc/init.d/apache2 script. PHP should now be available.

No, you can't forcefully close a connection in a clear way from the peripheral side. There is no API for it.

You can break the connection abruptly by not responding to a request, which results in disconnection at most after 30 seconds. This is the standard behavior defined by the Bluetooth specification Vol.3 Part F 3.3.3

A transaction not completed within 30 seconds shall time out. Such a transaction shall be considered to have failed and the local higher layers shall be informed of this failure. No more attribute protocol requests, commands, indica- tions or notifications shall be sent to the target device on this ATT Bearer.

Why not extend the helper?

Create a class in app/View/Helper/myTimeHelper.php. In there add the reference to the old class you'll be extended like:

App::uses('TimeHelper', 'View/Helper'); class myTimeHelper extends TimeHelper { public function niceShort(<whatever input the original is getting>) { // your new logic for the things you want to change // and/or a return TimeHelper::niceShort(<whatever>) for the cases that are //fine as they are. If you don't need that then you can remove App::uses. }

Finally you can have your helper imported as myTime with

public $helpers = array('myTime');

or even change the default Time to call myTime so you don't need to change anything else in your already written code:

public $helpers = array('Time' => array('className' => 'myTime'));

Examples of how these functions are used from curl are available in the README.markdown file.

You can pass an argument to each individual map or reduce phase function through the 'arg' parameter. Whatever you specify here will be passed on as the final parameter to the map or reduce phase, see the example below:

Is there a step-by-step guide on how to install RoR on a Fresh Ubuntu 10.10 machine? Like the first thing I need to do after booting up the system and starting the terminal?

Cheers, Ben

when you select the view and click on the attributes inspector see that background color property change the color you want.And also the attributes inspector click on the view show at the left side may be this hide so you can't see anything in the inspector area.

You reference the host control with the outerDocument property... so you would call outerDocument.DP_PRAT_INIT if you want to access that array. BUT, that array is private, so you have to make it public. Or, you can make a public function that you can call on outerDocument but ... yuck.

If I am understanding your code properly, you should access the data property of the GridItemRenderer which is the same as outerDocument.DP_PRAT_INIT[ddlTuVous.selectedIndex] except that it is better because you don't have possible index mismatches...

So, what you really want is:

data.prTuVous = ddlTuVous.selectedItem;

I would place lightweight proxy in front of media server like nginx. This would allow you to do load balancing AND any restrictions you need (you may only allow certain IPs on certain URLs).

It's a bitwise Or, if you have binary values it or's each of them together

00010110 10110000 --------- 10110110

For each bit, the output will have a 0, if both of the corresponding input's bits have a 0. If either or both input's bits have a 1, it will output 1 in that slot.

It's kinda like an ||, except it checks on each individual bit, instead of the whole number.

In your case

The way your particular example what you're doing is encoding 2 conditions into a single value, has to do with masking.

Suppose InputType.TYPE_CLASS_TEXT was equal to 8 or 00001000

And suppose InputType.TYPE_TEXT_VARIATION_PASSWORD was equal to 32 or 00100000

InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD would be equal to 00101000 or 40.

When you want to read them, you use bitwise anding. It's the exact opposite of oring. IT returns true only if both values are 1.

00010110 10110000 --------- 00010000

To check if your value contains a result, you simply and it to the type

00101000 - 40 - Your result 00001000 - 8 - InputType.TYPE_CLASS_TEXT -------- 00001000 - 8 - this means that your result contains `InputType.TYPE_CLASS_TEXT`

in code, the check might look like this.

if(myInputType & InputType.TYPE_CLASS_TEXT != 0) //myinput type cointains TYPE_CLASS_TEXT

40100910 0 What is the impact of async action method on IIS?

I need help in understanding how async action method can improve performance of IIS (and eventually my application).

First I tried to create Server Unavailable (503) with following code and setup

Application Queue Length: 10
IIS - Threads per processor limit: 2
Processors: 4

Sent 20 requests with SOAP UI and when tried from the browser, the browser showed 503, which is what I expected.

Then I made following changes in code

Sent 20 requests again with SOAP UI and when tried from the browser, the browser again showed 503, which I wasnt expecting.

Wouldn't the async and await release the thread to accept new connections?

Is my understanding correct on following

Maximum number of concurrent requests the server can accept at any given time is : (IIS Threads per processor limit * Number of processors + Application Queue Length) 18 in my case?
19th request would get a 503 in case of synchronous action methods?

You could loop through the AOT using the TreeNode class and select elements where the label property is blank. Then you can send the information out to the infolog or whatever you wish.

There are numerous code examples out there of how to do that, such as this one looping over forms selecting on the HTMLHelpTopic property.

You missed last } braces for loop. You put key as string it need to concadinate with + symbol like the below code.

 var data = { Name : "name", Price : 50 }; var modalId ='hai'; for(var key in data){ if (data.hasOwnProperty(key)) { console.log($('#'+modalId).find('input[name='+key+']')); console.log($('#'+modalId).find('textarea[name='+key+']')); console.log($('#'+modalId).find('select[name='+key+']')); } }

8471060 0 want to pass value using ref in c# but its not working like I think it should

Maybe what I want to do is just the wrong way of going about it. But i am trying to write a game debug printer thing. It is to write values to the screen in a sprite font for various things i tell the debugger to care about. My debugger class is simple , but it seems that in c# things are getting passed by value not reference. So I turn to the ref keyword, which seems to work okay if I pass in the right data type. The issue is that I have this method signature:

Dictionary<String, object> debugStrings = new Dictionary<String, object>(); ... ... public void addVariable(String index, ref object obj) //i think it needs to be a reference, not so sure though. { debugStrings.Add(index, obj); }

This adds to the dictionary a variable to ultimately print to the screen along with a key for it to be known as.

The problem though arises when I try to use the above method:

debugPrinter.addVariable("myrotationvalue", ref this.Rotation);

as per the link in the comment I changed the code above to:

this.Rotation = 4; object c = (object)this.Rotation; this.Rotation = 20; level.dbgd.addVariable("playerrot", ref c); //always prints 4 out, i guess it still is not passing by reference?

So it doesn't give an error but always prints out 4. Not sure how I will ever get the reference to work.

Again on another edit took the references out:

this.Rotation = 20; level.dbgd.addVariable("playerrot", this.Rotation); this.Rotation = 4; //should draw to screen 4, doesn't draws 20

I apparently this is harder than I thought it would be a simple little fun class to work up before I hit the hay, ha ha ha... this is not boding well for the monday to come.

Full class:

namespace GameGridTest.GameGridClasses.helpers { public class DebugDrawer : DrawableGameComponent { Dictionary<String, object> debugStrings = new Dictionary<String, object>(); int currentX; int currentY; VictoryGame _game; private SpriteBatch spriteBatch; private SpriteFont spriteFont; public DebugDrawer(VictoryGame game) : base(game) { _game = game; currentX = _game.Window.ClientBounds.Width - 400; //draw the debug stuff on right side of screen currentY = 5; } protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); spriteFont = _game.Content.Load<SpriteFont>("fonts\\helpers\\fpsFont"); } public void addVariable<T>(String index, AbstractDebugHandler<T> obj) //i think it needs to be a reference, not so sure though. { debugStrings.Add(index, obj); } public void removeVariable(String index) { debugStrings.Remove(index); } protected override void UnloadContent() { _game.Content.Unload(); } public override void Update(GameTime gameTime) { } public override void Draw(GameTime gameTime) { spriteBatch.Begin(); foreach (object obj in debugStrings) //draw all the values { spriteBatch.DrawString(spriteFont, obj.ToString(), new Vector2(currentX, currentY), Color.White); currentY += 30; } currentY = 5; spriteBatch.End(); } } public abstract class AbstractDebugHandler<T> { public AbstractDebugHandler(T obj) { InnerObject = obj; } public T InnerObject { get; private set; } public abstract string GetDebugString(); } public class ThisDebugHandler: AbstractDebugHandler<object>{ public ThisDebugHandler(object innerObject) : base(innerObject){ } public override GetDebugString(){ return InnerObject.Rotation; //?? } } }

Edit

I just found this jQuery plugin - http://markdalgleish.com/projects/tmpload/ Does exactly what you want, and can be coupled with $.tmpl

I have built a lightweight template manager that loads templates via Ajax, which allows you to separate the templates into more manageable modules. It also performs simple, in-memory caching to prevent unnecessary HTTP requests. (I have used jQuery.ajax here for brevity)

var TEMPLATES = {}; var Template = { load: function(url, fn) { if(!TEMPLATES.hasOwnProperty(url)) { $.ajax({ url: url, success: function(data) { TEMPLATES[url] = data; fn(data); } }); } else { fn(TEMPLATES[url]); } }, render: function(tmpl, context) { // Apply context to template string here // using library such as underscore.js or mustache.js } };

You would then use this code as follows, handling the template data via callback:

Template.load('/path/to/template/file', function(tmpl) { var output = Template.render(tmpl, { 'myVar': 'some value' }); });

yes, I tried with hex capable ones...but I m still getting an empty window.Is there any best editor u may suggest though?

It sounds like the files may really be empty apart from that \000 character; i.e. you've completely trashed them. You can confirm this by looking at the file sizes as reported by the operating system.

If you have trashed the files, and it is unlikely that NetBeans can get the old contents back. You will need to restore latest versions the files from version control (SVN, GIT, whatever you are using) or from a file system backup. If that doesn't work you might be able to recover them with a file recovery tool, but I doubt it.

The lessons is to make sure your source files are safely in version control or backed up before you use some code generator to update them.

I don't think that is due to memory leak. It has happened to me too when I tried to copy only the compiled executable but not depend libraries. So just check whether all depend libraries are available in other systems too.

If the problem domain is hard (and AI problems can often be hard), then I'd choose a language which is expressive or suited to the domain first, and then worry about speeding it up second. For example, Ruby has meta-programming primitives (ability to easily examine and modify the running program) which can make it very easy/interesting to implement certain types of algorithms.

If you implement it in that way and then later need to speed it up, then you can use benchmarking/profiling to locate the bottleneck and either link to a compiled language for that, or optimise the algorithm. In my experience, the biggest performance gain is from tweaking the algorithm, not from using a different implementation language.

You are looking for consecutive values. Here is one way, using a difference of row numbers to identify a group:

with t as (<your query here>) select min(term_start), max(term_end), block, quantity from (select t.*, (row_number() over (partition by block order by position) - row_number() over (partition by quantity, block order by position) ) as grp from t ) t group by quantity, grp, block;

I am loading pages within a content div with .load() function and using window.onhashchange event to detect if the user is navigated.

window.onhashchange = function() { hash(window.location.hash.replace('#', '')) }

and

function hash(s) { $('.panel-body').fadeOut(100).load(s+'.php').fadeIn(100) }

Some of the pages takes long to load everytime. I don't want them to be reloaded (bypass .load() function) if the state is already cached. Any workaround?

There is no built-in NSString method available to do what you want. You need to write your own method. Objective-C does let you "extend" classes with new methods to cover cases like this.

This is how I would do it:

@interface NSString(Extend) -(NSInteger)proximity:(NSString*)otherString; @end @implementation NSString(Extend) -(NSInteger)proximity:(NSString*)otherString { NSUInteger length = [otherString length]; if(length != [self length]) return -1; NSUInteger k; NSUInteger differences = 0; for(k=0;k<length;++k) { unichar c1 = [self characterAtIndex:k]; unichar c2 = [otherString characterAtIndex:k]; if(c1!=c2) { ++differences; } } return differences; } @end

Then in my code at the place I wanted to check I would say something like

11551794 0 multiply two decimals

Im trying to add a tax field. I have this working for whole numbers but i need to be able to enter ".5" I have no clue haw to solve this problem maybe its because of the isNAN but i thought this would be ok here.

While for this example it might be overkill here is a way to extend the TListView class with a SelectedItem property that is enumerable with a for-in loop.

In cases where the condition inside the loop might be more complex than just checking a property or by actually providing a filter delegate this can be very powerful.

type TSelectedListItemsEnumerator = class(TListItemsEnumerator) public function MoveNext: Boolean; end; TSelectedListItemsEnumerable = record private FListItems: TListItems; public constructor Create(AListItems: TListItems); function GetEnumerator: TSelectedListItemsEnumerator; end; TListViewHelper = class helper for TListView private function GetSelectedItems: TSelectedListItemsEnumerable; public property SelectedItems: TSelectedListItemsEnumerable read GetSelectedItems; end; { TSelectedListItemsEnumerator } function TSelectedListItemsEnumerator.MoveNext: Boolean; begin repeat Result := inherited; until not Result or Current.Selected; end; { TSelectedListItemsEnumerable } constructor TSelectedListItemsEnumerable.Create(AListItems: TListItems); begin FListItems := AListItems; end; function TSelectedListItemsEnumerable.GetEnumerator: TSelectedListItemsEnumerator; begin Result := TSelectedListItemsEnumerator.Create(fListItems); end; { TListViewHelper } function TListViewHelper.GetSelectedItems: TSelectedListItemsEnumerable; begin Result := TSelectedListItemsEnumerable.Create(Items); end;

You can then use it like this:

procedure TForm1.Button1Click(Sender: TObject); var item: TListItem; begin for item in ListView1.SelectedItems do begin ShowMessage(item.Caption); end; end;

WPF supports two different flavors of focus:

Keyboard focus
Logical focus

The FocusedElement property gets or sets logical focus within a focus scope. I suspect your TextBox does have logical focus, but its containing focus scope is not the active focus scope. Ergo, it does not have keyboard focus.

So the question is, do you have multiple focus scopes in your visual tree?

However, did you know that read will join lines with \ newline continuations by default?

public class SavingsAccount { private static int accountNumber = 1000; private bool active; private decimal balance; public SavingsAccount(bool active, decimal balance, string accountType) { accountNumber++; this.active = active; this.balance = balance; this.accountType = accountType; } }

Why is it that when I plug this in main like so:

class Program { static void Main(string[] args) { SavingsAccount potato = new SavingsAccount(true, 100.0m, "Savings"); SavingsAccount magician = new SavingsAccount(true, 200.0m, "Savings"); Console.WriteLine(potato.ToString()); Console.WriteLine(magician.ToString()); } }

The output I get does not increment it individually i.e.

savings 1001 savings 1002

but instead I get:

savings 1002 savings 1002

How do I make it to be the former and not the latter?

this is a route I defined:
GET /user/:id controllers.Users.show(id: Long)

this is the handler (in Users class) for this GET requset:

public static Result show(long id) { return ok("hello " + id); }

I get this error:

this is weird because it's the only page with this problem and everything seems to be normal.

29571350 0 Replacing an Element in jQuery

I'm trying to modify an element in jQuery programmatically, i.e. a number in docID increments up to a maximum number. I'm replacing text on a series of images on a page from Download to View. If I use #ctl00_cphMainContent_dlProductList_ct100_ctl00_lnkProofDownload instead of docID in the $(docID).text(...) part of the code, the text gets replaced correctly. When I use the docID variable in its place, it doesn't work.

What am I doing wrong here?

Thanks.

var max = 10; var count = 100; var s1 = "#ctl00_cphMainContent_dlProductList_ct"; var s2 = "_ctl00_lnkProofDownload"; var docID = ""; for (i = 1; i <= max; i++) { docID = s1.concat (count++, s2); $(document).ready(function() { $(docID).text(function(i, oldText) { return oldText === 'Download' ? 'View' : oldText; }); }); }

This is the HTML code that is being modified. The word Download is replaced by View.

If the other suggestions don't work, it may be a problem with your terminal. My gnome-terminal on Ubuntu was scrolling much slower than PuTTY with the same file.

If you're using Ubuntu's default gnome-terminal, you might want try another terminal program. urxvt both worked for me (terminator had similar problems):

$ sudo apt-get install rxvt-unicode $ urxvt

The major downside is that it doesn't look very good. You can try the advice here to make it look a bit better

When user launch the application you could show a splash screen for 1 or 2 second after that you could show the progress (status) of your application using text msg.

for example "Initialization of Synchronization Service" ,"Storing to data base", "Loading map" .

The above text msg. is just a reference,you could have more descriptive text to show on screen along with progress bar.

'x' does not interpolate the x variable into the string. You need to do something like this:

xpathName = "/html/body/div[2]/table/tbody/tr[%d]/td[4]//text()" % (x,) xpathTime = "/html/body/div[2]/table/tbody/tr[%d]/td[9]//text()" % (x,)

Also, as @grael mentioned, you need to terminate your loop somewhere.

The Go Programming Language Specification

Empty statements

The empty statement does nothing.

EmptyStmt = .

Notation

The syntax is specified using Extended Backus-Naur Form (EBNF):
Production = production_name "=" [ Expression ] "." . Expression = Alternative { "|" Alternative } . Alternative = Term { Term } . Term = production_name | token [ "…" token ] | Group | Option | Repetition . Group = "(" Expression ")" . Option = "[" Expression "]" . Repetition = "{" Expression "}" . 
Productions are expressions constructed from terms and the following operators, in increasing precedence:
| alternation () grouping [] option (0 or 1 times) {} repetition (0 to n times) 
Lower-case production names are used to identify lexical tokens. Non-terminals are in CamelCase. Lexical tokens are enclosed in double quotes "" or back quotes ``.

The form a … b represents the set of characters from a through b as alternatives. The horizontal ellipsis … is also used elsewhere in the spec to informally denote various enumerations or code snippets that are not further specified. The character … (as opposed to the three characters ...) is not a token of the Go language.

The empty statement is empty. In EBNF (Extended Backus–Naur Form) form: EmptyStmt = . or an empty string.

For example,

for { } var no if true { } else { no = true }

The problem is that server side redirection is only redirecting your inner app frame instead of redirecting the whole page, and Facebook doesn't like displaying their system dialogs inside frames.

You would need some client side redirection, probably something along those lines:

I need to set a custom route value so that you are forced to go to

site/admin/elmah.axd

In my web.config I have:

<location path="elmah.axd"> <system.web> <authorization> <allow roles="Admin" /> <deny users="*" /> </authorization> </system.web> </location>

Plus all the other pertinent elmah settings. If I remove that section I can just type:

site/elmah.axd

But I only want Admin's to be able to access this page.

I have an admin page that you login and if you are in the Admin Role then you should be redirected to elmah.axd

 public AdminController(IRepository<User> userRepository) { _userRepository = userRepository; } // // GET: /Admin/ public ActionResult Index() { return View(Constants.Admin); } public ActionResult AdminLogin(string SSN) { var user = _userRepository.FindBy(x => x.UserName == SSN).SingleOrDefault(); if (UserIsAnAdmin(user)) { return RedirectToRoute("/elmah.axd"); } return View(Constants.DeniedAccess); }

I have a route value in my Global.asax file that I need help with.

 routes.MapRoute( "mocklogin", "{controller}/{action}", // URL with parameters new { controller = "MockLogin", action = "Index" } // Parameter defaults ); routes.MapRoute( "elmah.axd", "{controller}/{action}", // URL with parameters ); routes.MapRoute( "Default", // Route name "{controller}/{action}", // URL with parameters //need something here redirecting to the elmah.axd page );

Is there a way to redirect the page to the /elmah.axd page on my site.

In the end I want to go to the Admin page of my site and when I click submit if the User is an admin I want to redirect to the elmah.axd page. Otherwise I go to my custom error page. I need to somehow get the ssn on the controller call the conditional and if true redirect to elmah.axd. How do I redirect to elmah.axd in MVC?

I believe gmch's answer should solve the original question. However, not all pthread implementations include pthread_barrier_t and the related functions (as they are an optional part of the POSIX threads specs), so here is the custom barrier implementation I mentioned in a comment to the original question.

(Note that there are other ways to suspend/resume threads asynchronously, during normal operation, and without co-operation from the threads themselves. One way to implement that is to use one or two realtime signals, and a signal handler that blocks in sigsuspend(), waiting for the complementary "continue" signal. The controlling thread will have to use pthread_kill() or pthread_sigqueue() to send the pausing and continuing signals to each thread involved. The threads are minimally affected; aside from possible EINTR errors from blocking syscalls (as signal delivery interrupts blocking syscalls), the threads just don't do any progress -- just as if they weren't scheduled for a while. Because of that, there should not be any issues with respect to the threads getting paused and continued at slightly different times. If you are interested in this method, leave a comment, and I could try and show an example implementation of that, too.)

Perhaps this will be of use to someone else needing a pause-able custom barrier implementation, or perhaps as a basis of their own custom barrier.

Edited to add DRAINING mode, when threads are expected to quit. In your worker loop, use do { ... } while (!barrier_wait(&barrier));

The logic is quite simple. All threads waiting in the barrier wait on the cond condition variable. If the barrier operates normally (state==RUNNING), the final thread arriving at the barrier will broadcast on the condition variable instead of waiting on it, thus waking up all other threads.

If the barrier is paused (state==PAUSED), even the final thread arriving at the barrier will wait on the condition variable.

When barrier_pause() is called, the barrier state is changed to paused. There may be zero or more threads waiting on the condition variable, and that is okay: only the final thread arriving at the barrier has a special role, and that thread cannot have yet arrived. (If it had, it'd have emptied the barrier already.)

When barrier_continue() is called, the barrier state is changed to normal (state==RUNNING). If all threads are waiting on the condition variable, they are released by broadcasting on the condition variable. Otherwise, the final thread arriving at the barrier will broadcast on the condition variable and release the waiting threads normally.

Note that barrier_pause() and barrier_continue() do not wait for the barrier to become full or to drain. It only blocks on the mutex, and the functions only hold it for very short periods at a time. (In other words, they may block for a short time, but will not wait for the barrier to reach any specific situation.)

If the barrier is draining (state==DRAINING), threads arriving at the barrier return immediately with errno==ETIMEDOUT. For simplicity, all the barrier functions now unconditionally set errno (to 0 if success, errno code if error, ETIMEDOUT if draining).

The mutex protects the barrier fields so that only one thread may access the fields at once. In particular, only one thread can arrive at the barrier at the same time, due to the mutex.

One complicated situation exists: the loop body the barrier is used in might be so short, or there might be so many threads, that threads start arriving at the next iteration of the barrier even before all threads from the previous iteration have left it.

According to POSIX.1-2004, pthread_cond_broadcast() "shall unblock all threads currently blocking on the specified condition variable". Even though their wakeups will be sequential -- as each one will acquire the mutex in turn --, only those threads that were blocked on it when pthread_cond_broadcast() was called will be woken up.

So, if the implementation follows POSIX semantics with respect to condition variables, woken threads can (even immediately!) re-wait on the condition variable, waiting for the next broadcast or signal: the "old" and "new" waiters are separate sets. This use case is actually quite typical, and all POSIX implementations I've heard of do allow that -- they do not wake up threads that started waiting on the condition variable after the last pthread_cond_broadcast().

If we can rely on POSIX condition variable wakeup semantics, it means the above barrier implementation should work reliably, including in the case where threads arrive at the barrier (for the next iteration), even before all threads (from the previous iteration) have left the barrier.

(Note that the known "spurious wakeups" issue only affects pthread_cond_signal(); i.e. when calling pthread_cond_signal() more than one thread may be woken up. Here, we wake up all threads using pthread_cond_broadcast(). We rely on it only waking current waiters, and not any future waiters.)

Here is a POSIX.1-2001 implementation for suspending and resuming threads asynchronously, without any co-operation from the target thread(s).

This uses two signals, one for suspending a thread, and another for resuming it. For maximum compatibility, I did not use GNU C extensions or POSIX.1b realtime signals. Both signals save and restore errno, so that the impact to the suspended threads would be minimal.

Note, however, that the functions listed in man 7 signal, "Interruption of system calls and library functions by signal handlers" section, after the "The following interfaces are never restarted after being interrupted by a signal handler" paragraph, will return errno==EINTR when suspended/resumed. This means you will have to use the traditional do { result = FUNCTION(...); } while (result == -1 && errno == EINTR); loop, instead of just result = FUNCTION(...);.

The suspend_threads() and resume_threads() calls are not synchronous. The threads will be suspended/resumed either before, or sometime after, the function calls return. Also, suspend and resume signals sent from outside the process itself may affect the threads; it depends on if the kernel uses one of the target threads to deliver such signals. (This approach cannot ignore signals sent by other processes.)

Testing indicates that in practice, this suspend/resume functionality is quite reliable, assuming no outside interference (by sending signals caught by the target threads from another process). However, it is not very robust, and there are very few guarantees on its operation, but it might suffice for some implementations.

I would recommend posting to the Register method and based on the value of the selected option, redirect to the relevant view to complete the details. The users table could have a (say) IsRegistrationComplete field which is marked as true only when the 2nd form has been saved.

To do this in one view, you will need a view model with properties for the Register model, Owner model, ServiceCompany model and selected option.

View model

public class RegistrationVM { public RegisterVM Register { get; set; } public OwnerVM Owner { get; set; } public ServiceCompanyVM ServiceCompany { get; set; } [Required] public string CompanyType { get; set; } }

Controller

public ActionResult Register() { RegistrationVM model = new RegistrationVM(); model.Register = new RegisterVM(); return View(model); } public ActionResult Register(RegistrationVM model) { // Either Owner or ServiceCompany properties will be populated } public PartialViewResult CreateOwner() { var model = new RegistrationVM(); model.Owner = new OwnerVM(); return PartialView(model); } public PartialViewResult CreateServiceCompany() { var model = new RegistrationVM(); model.ServiceCompany = new ServiceCompany(); return PartialView(model); }

Notes: The partial views should not contain a <form> element (it will be inserted inside the <form> tag of the main view). The model in the partial views needs to be RegistrationVM so the controls are correctly prefixed and can be bound on post back (e.g. <input name="Owner.SomeProperty" ../> etc)

View

@model RegistrationVM @using(Html.BeginForm()) { <section> // render controls for the register model <section> <section> @Html.RadioButtonFor(m => m.CompanyType, "owner",new { id = "owner" }) <label for="owner">Owner</label> @Html.RadioButtonFor(m => m.CompanyType, "service",new { id = "service" }) <label for="service">Service Company</label> @Html.ValidationMessageFor(m => m.CompanyType) <button id="next" type="button">Next</button> <section> <section id="step2"></section> <input id="submit" type="submit" /> // style this as hidden }

Then add a script to handle the Next button which validates the existing controls, gets the value of the selected service, uses ajax to load the relevant form, re-parses the validator and displays the submit button

var form = $('form'); $('#next').click(function() { // Validate what been entered so far form.validate(); if (!form.valid()) { return; // correct errors before proceeding } // Get selected type and update DOM var type = $('input[name="CompanyType"]:checked').val(); if (type == "owner") { $('#step2').load('@Url.Action("CreateOwner")'); } else { $('#step2').load('@Url.Action("CreateServiceCompany")'); } // Re-parse validator so client side validation can be applied to the new controls form.data('validator', null); $.validator.unobtrusive.parse(form); // Show submit button $('#submit').show(); });

In your view code for the 'new' action use FormHelper tags that reference the same model as your create action eg.

<%= text_field :user, :login %>

Then in your create action, use a model instance with the same name:

@user = User.new # detect error, redirect to 'new'

The FormHelper will use the value of this instance if it is available.

Flexibility

Since Bootstrap is a library, they realize that some people will not want to use classes from Bootstrap, but will want to use the mixins. By keeping the separation, a user can import mixins.less and apply .clearfix() into their own code under their own class name(s), without it actually creating an output of a .clearfix class itself. At the same time, if one wants to use the whole Bootstrap library, they want to provide an actual class by the name .clearfix for users of the whole library.

Currently I'm thinking of using .htaccess to process .css/.svg as PHP and drop the values in from there, but is there a more efficient/elegant way without having to process these file formats as PHP?

All advice appreciated.

Many thanks.

18877882 0 draw rectangle in Jpanel

I am trying to get my hands on GUI programming in java and wanted to draw a rectangle in Jpanel. Code does not give any error but I cannot get rectangle in the GUI. Can somebody please tell me what I am missing in the following code. I am sure it is pretty simple so please be gentle.

import java.awt.*; import java.awt.event.*; import javax.swing.*; public class HelloWorldGUI2 { private static class ButtonHandler implements ActionListener { public void actionPerformed(ActionEvent e) { System.exit(0); } } private static class RectDraw extends JPanel { public void paintComponent(Graphics g) { super.paintComponent(g); g.drawRect(230,80,10,10); g.setColor(Color.RED); g.fillRect(230,80,10,10); } } public static void main(String[] args) { JPanel content = new JPanel(); RectDraw newrect= new RectDraw(); JButton okButton= new JButton("OK"); JButton clearButton= new JButton("Clear"); ButtonHandler listener= new ButtonHandler(); okButton.addActionListener(listener); clearButton.addActionListener(listener); content.add(okButton); content.add(clearButton); content.add(newrect); JFrame window = new JFrame("GUI Test"); window.setContentPane(content); window.setSize(250,100); window.setLocation(100,100); window.setVisible(true); } }

Right answer would be declaring a common base class or interface but you said "I tried polymorphism, but". I do not know what (or how) did you try but assuming,

You are sure that all classes have a ToModel() method
It is not practical to declare a common interface or base class for your classes
You are using .NET 4.0 or above

You can do

var type = _projectService.GetTaskTypeById(id); dynamic task; switch (type) { case "MS": task = _projectService.GetMSTaskById(id); break; case "TL": task = _projectService.GetTLTaskById(id); break; case "ET": task = _projectService.GetETTaskById(id); break; default: throw new NotSupportedException("Unsupported Task Type: " + type); } task.ToModel();

I would recommend to just do it in code for full control and additional possibilities later on.

Simply set the background color of the concerned tableview. In your case that would be something like this:

self.navigationController.view.backgroundColor = [UIColor whiteColor];

OrderBy returns a new IEnumerable, so you need to do something like:

IEnumerable<Data> results = query.OrderBy(item => item.GetType().GetProperty(sortExpressions[i].Name));

15963402 0 Bulktransfer returns -1

First let me state that I am brand new to Android Development so maybe USB is a bit complex for a first app but it is my only reason for wanting to write an app in the first place.

I would like to communicate to a Garmin GPS over USB. I have done so in the past with success from the PC but it was via a driver supplied by Garmin.

As far as I am aware there is no such driver for Android so I need to write directly to the USB.

Garmin publishes this documentation:

http://www8.garmin.com/support/pdf/USBAddendum.pdf

Basically it says you must transmit on bulk out: 00 00 00 00 05 00 00 00 00 00 00 00

to tell the device to prepare for a transfer. When I do so, my bulktransfer fails with -1. If I have a 0 for the timeout then bulktransfer never returns. I assume becuase there is no response from the gps.

I have included my code below. The code detects the GPS and opens it. But the first bulktransfer never completes. I am certain I am sending to the bulk out endpoint. Can anyone get me started?

 public class MainActivity extends Activity { private static final String TAG = "TestGarmin"; private UsbManager mUsbManager; private UsbDevice mDevice; private UsbDeviceConnection mConnection; private UsbEndpoint mEndpointIntr; private UsbEndpoint mEndpointBulkOut; private UsbEndpoint mEndpointBulkIn; private static int TIMEOUT = 0; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mUsbManager = (UsbManager)getSystemService(Context.USB_SERVICE); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } public void onResume() { super.onResume(); Intent intent = getIntent(); Log.d(TAG, "intent: " + intent); String action = intent.getAction(); String s = UsbManager.ACTION_USB_DEVICE_ATTACHED; UsbDevice device = (UsbDevice)intent.getParcelableExtra(UsbManager.EXTRA_DEVICE); if (UsbManager.ACTION_USB_DEVICE_ATTACHED.equals(action)) setDevice(device); } private void setDevice(UsbDevice device) { Log.d(TAG, "setDevice " + device); if (device.getInterfaceCount() != 1) { Log.e(TAG, "could not find interface"); return; } UsbInterface intf = device.getInterface(0); // device should have three endpoints if (intf.getEndpointCount() != 3) { Log.e(TAG, "could not find endpoint"); return; } // endpoint 0 should be of type interrupt UsbEndpoint ep0 = intf.getEndpoint(0); if (ep0.getType() != UsbConstants.USB_ENDPOINT_XFER_INT) { Log.e(TAG, "endpoint 0 is not interrupt type"); return; } if (ep0.getDirection() != UsbConstants.USB_DIR_IN) { Log.e(TAG, "endpoint 0 is not an input endpoint"); return; } mEndpointIntr = ep0; // endpoint 1 should be of type bulk UsbEndpoint ep1 = intf.getEndpoint(1); if (ep1.getType() != UsbConstants.USB_ENDPOINT_XFER_BULK) { Log.e(TAG, "endpoint 1 is not bulk type"); return; } if (ep1.getDirection() != UsbConstants.USB_DIR_OUT) { Log.e(TAG, "endpoint 1 is not an output endpoint"); return; } mEndpointBulkOut = ep1; // endpoint 2 should be of type bulk UsbEndpoint ep2 = intf.getEndpoint(2); if (ep2.getType() != UsbConstants.USB_ENDPOINT_XFER_BULK) { Log.e(TAG, "endpoint 2 is not bulk type"); return; } if (ep2.getDirection() != UsbConstants.USB_DIR_IN) { Log.e(TAG, "endpoint 2 is not an output endpoint"); return; } mEndpointBulkOut = ep2; mDevice = device; if (device != null) { UsbDeviceConnection connection = mUsbManager.openDevice(device); if (connection != null && connection.claimInterface(intf, true)) { Log.d(TAG, "open SUCCESS"); mConnection = connection; byte[] init = {0x00,0x00,0x00,0x00,0x05,0x00,0x00,0x00,0x00,0x00,0x00,0x00}; //14 00 00 00 FE 00 00 00 00 00 00 00 int x = connection.bulkTransfer(mEndpointBulkOut,init, init.length, 100); Log.e(TAG, "BulTransfer returned " + x); } else { Log.d(TAG, "open FAIL"); mConnection = null; } } } }

Just to note that this was resolved in Django 1.8 with the addition of the from_db_value method on custom fields.

See https://docs.djangoproject.com/en/1.8/howto/custom-model-fields/#converting-values-to-python-objects

8097820 0 Detect time taken to type into Autocomplete field and auto select if only one item found

Right, I've nearly found what I'm after but not quite.

Given a simple jQUery call to Autocomplete

 $(".autoItem").each(function () { var id = $(this).attr("id"); var itemNumber = id.replace('item', ''); $(this).autocomplete({ source: "jsonOut/products.aspx", minLength: 2, select: function (event, ui) { $('#price' + itemNumber).val(ui.item.price); $('#id' + itemNumber).val(ui.item.id); } }); });

Which works lovely, I am now over complicating it as usual due to my application.

This is for a web form for making sales in a shop. The text box can be populated by two methods:

A) Simply typing as normal.
B) Scanning a code with a bar code scanner.

In case A, everything's fine, autocomplete works exactly as autocomplete was intended.

In case B though, I have two issues:

I need to be able to detect that this entry is from a scanner, so that the code behind knows to search the barcode field of my database, not item titles. Clearly the browser's not gonna know that, so the only way I can think is to do it by time. The scanner will populate the field faster than anyone can type.
Once a result has been generated by AutoComplete with a barcode, it will clearly only return one result, so in cases where only one result is returned, I want it to auto-select that result and run it's select function populating the other fields as required.

(the bar code scanner has a TAB terminator, so after scanning it immediately blurs the text field an moves on to the next one)

Would something like this be possible?

If someone could help with issue in isolation, that'd be cool. I have looked at https://github.com/scottgonzalez/jquery-ui-extensions/blob/master/autocomplete/jquery.ui.autocomplete.selectFirst.js for point B, but couldn't get it to work.

NOTE: If the worst comes to the worst, I could detect scanned entries by using isNumeric in the code behind, BUT, some codes we scan are not numeric, clearly proper UPC codes are, but we have some items with barcodes generated from product SKUs, these might not be numeric.

It's definitely not the idea of MVC (or whatever you're doing) to render HTML in the Controller. HTML has to be handled in the view. What if you want to provide an alternative UI (e.g. Windows Application)? HTML does not really fit into an WinApp.

You can't do that unless the subroutine is a built-in Perl operator, like sqrt for instance, when you could write

perl -e "print sqrt(2)"

or if it is provided by an installed module, say List::Util, like this

perl -MList::Util=shuffle -e "print shuffle 'A' .. 'Z'"

26040440 0 Remove Duplicates Linq Query Dropdownlist in VB.net

16990726 0 NSMenuDelegate methods not called for contextual menu

I have a Document based application. I want to add a contextual menu that displays context-sensitive info when the user right-clicks selected text in an NSTextView.

I have followed the advice in the Apple documentation and

Added an NSMenu as a root object in my XIB file.
Connected the NSMenu instance to the menu outlet of the NSTextView.
Connected an IBAction to the NSMenuItem inside the NSMenu.

So far so good. Every thing works as expected: the menu item appears and the action is called when it is selected.

I need to get the selected text from the NSTextView before the menu appears so that I can configure my menu item appropriately. According to the docs

If you need to customize the contextual menu, you can do so by setting an appropriate object as the menu’s delegate and implementing the menuWillOpen: method to customize the menu as you see fit just before it appears.

I connect the delegate of the NSMenu to File's Owner. None of the delegate methods are called. ( menuWillOpen: is the only one I need, but I've tried others, too).

I set a breakpoint inside the IBAction that gets called when the menu item is selected. If I inspect the menu with the debugger I can see that the delegate is correctly set to the object that implements the delegate method.

Is there anything else to check? Anything I'm doing blatantly wrong?

You can create a Blob for this, but it won't be "saved" to the client's device. The Blob can then be submitted to the server using an XMLHttpRequest

// bytes , mime var b = new Blob(['text data'], 'text/plain'); // make it easy to submit or just submit it directly var fd = new FormData(); fd.append('fileParam', b, 'file_name.txt'); // assuming XMLHttpRequest xhr xhr.send(fd);

If FormData is not available for the device, then you can send the blob directly. Adding a FormData makes the server side easier as it is the same as if you submitted a <form> with some <input>.

Finally I tried to work with different USB<->CAN interface from different manufacturer and it worked like a charm. My old interface was either broken or incompatible for reasons unknown. While working on this problem I learned couple of things about CAN bus and so now I share what I think was the right answer to my original question: How to troubleshoot CAN bus communication?

read manual to your USB-CAN interface
install driver of your interface device and make sure it is working (check device manager, depending on the type of your device you will see new COM port added or new USB controller )
your device should be shipped with it's own test/analysis software (they might call it utility or similar), run it and check if it can connect to your device
CAN communication uses three wires that are referred to as High, Low and Ground and is usually connected with DB-9 connectors where High is linked to pin n. 7, Low to pin n. 2 and Ground to pin n. 3 or 5 - make sure this is connected correctly on both your USB interface and CAN device you want to communicate with
set properties of your connection, these are most of all: CAN type (2.0A or 2.0B) BAUD rate, Acceptance Code and Acceptance Mask
if you've done all of this and still you can see no CAN messages arriving in your utility program, check with a different USB-CAN interface or find some other way to test if your device is actually emitting CAN messages and your USB interface is in fact able to receive them. (this was actually my case)

Streaming to string is already implemented, you can use

Writing: TClientDataSet.SaveToFile or TClientDataSet.SaveToStream

Reading: TClientDataSet.LoadFromFile or TClientDataSet.LoadFromStream

procedure SaveToStream(Stream: TStream; Format: TDataPacketFormat = dfBinary); procedure SaveToFile(const FileName: string = ''; Format: TDataPacketFormat = fBinary); procedure LoadFromStream(Stream: TStream); procedure LoadFromFile(const FileName: string = '');

the TDataPacketFormat options are:

dfBinary: Information is encoded in binary format.
dfXML:Information is encoded in XML, with extended characters encoded using an escape sequence.
dfXMLUTF8:Information is encoded in XML, with extended characters represented using UTF8.

Using dfXMLUTF8 you should have no problems with non/ansi characters sets.

36878498 0 What the " {% " in a javascript code suppose to mean?

I'm applying to a front-end test, that have a page that i might develop a responsive version. So i git clone they repository, run npm install, run grunt and when i finally open the html at browser i receive this error at console:

So i go find why this is happening, and i found this javascript:

var marker = new google.maps.Marker({ map: map, icon: { url: '{% static "assets/images/marker_center.png" %}', size: new google.maps.Size(71, 156), origin: new google.maps.Point(0, 0), anchor: new google.maps.Point(38, 95) }, position: pyrmont });

So i thought that's this {% was a sintaxe used at google maps api, but it isn't. It's not required, i can just write the path to the image and the page run without errors. My question is, why they put {% ?

14710042 0 IE img load returns error

I am trying to insert an image from an ajax repsonse. Everything work, but not in IE.

I have tried: Image load not working with IE 8 or lower, but get "broken image".

Tried to solve it described here: http://www.paulund.co.uk/handle-image-loading-errors-with-jquery, but it does not solve anything. I did not attach it to the document.ready function though, since this is ajax, the IE < 9 hack will never be triggered by the ajax call. the Ajax call is triggered by a mouse click which repsonds with an image link. When using JQuery's dialog function, IE does not show the image. Forcing it by right-clicking and 'Show image' shows the image.

Anybody know how to solve this problem?

You can simply put the conditions with the range of data types and check whether the input number falls in which data type.

 class FindDataType { public static void main(String[] argh) { Scanner sc = new Scanner(System.in); //no. of input values int t = sc.nextInt(); for (int i = 0; i < t; i++) { try { //Take input as long data type long x = sc.nextLong(); System.out.println(x + " can be fitted in:"); //Putting conditions to check the data type if (x >= -128 && x <= 127) { System.out.println("* byte"); System.out.println("* short"); System.out.println("* int"); System.out.println("* long"); } else if (x >= -32768 && x <= 32767) { System.out.println("* short"); System.out.println("* int"); System.out.println("* long"); } else if (x >= -2147483648 && x <= 2147483647) { System.out.println("* int"); System.out.println("* long"); } else if (x >= -9223372036854775808l && x <= 9223372036854775807l) { System.out.println("* long"); } } catch (Exception e) { //Printing exception if no data type matches. System.out.println(sc.next() + " can't be fitted anywhere."); } } sc.close(); }}

I'm not sure if this is you intention, but it's weird to me...

First, you declare a class that extends from JFrame...

public class login extends JFrame {

Then you declare a instance variable of the same class...

JFrame login = new JFrame();

You than add all your components to this instance...

login.add(panel1); login.add(panel2); login.add(panel3);

Now, I can't see how you are using this, but I imagine you are doing something like...

login login = new login() login.setVisible(true);

Which basically, doesn't show anything...

Instead. Rather than extending from JFrame, I would extend from JPanel and drop the login instance variable.

Create a instance of login and then add it to a JFrame instance that you have created...

I also recommend that you take a look at Code Conventions for the Java Programming Language

5833218 1 CoreDumpDirectory isn't working on ubuntu; getting segmentation fault in apache2 error log

I am not able to log the apache2 crashes in CoreDumpDirectory on ubuntu 10.10. I am using Django 1.2.3 and apache2 with mod_wsgi. I followed the steps listed in response to this question but to no avail. I added - CoreDumpDirectory /var/cache/apache2/
at the end of apache2.conf file and then after executing 'ulimit -c unlimited', restarted the apache server. Then I replicated the condition that causes apache error log to show- "child pid 27288 exit signal Segmentation fault (11)" but there is no mention of apache2 logging that crash in CoreDumpDirectory and also there is nothing in /var/cache/apache2.

EDIT:

I was able to solve this problem. The issue was with PyLucene environment being initialized on the run time. I was executing initvm() call everytime a request comes and it was causing segmentation fault. This link directed that I should do it in .wsgi file and after I did that there were no segmentation faults.

linking a trackbar and a textfield is very easy in windows forms. it is like this: textBox.DataBindings.Add("Text", trackBar, "Value");

the problem is, that trackbars only allow for integer values but i want to have floating point values. so i usually just divide the value by 100, since on the trackbar the value is not directly visible to the user. but in the textbox it is.

so is it possible to link these two with a factor of 100?

thanks!

Usually Tag property will be of type Object, so I assume it is of type Object. == operator with System.Object work as reference comparison (meaning references of the instances are compared than value).

To fix it just introduce a cast to string.

if ((string)answer[0].Tag == "bla bla" && (string)answer[1].Tag== "blabla2") { MessageBox.Show("They Match"); } else { MessageBox.Show("They don't"); }

Application shortcuts:

You can list installed applications with:

final PackageManager pm = getPackageManager(); //get a list of installed apps. List<ApplicationInfo> packages = pm .getInstalledApplications(PackageManager.GET_META_DATA); for (ApplicationInfo packageInfo : packages) { Log.d(TAG, "Installed package :" + packageInfo.packageName); Log.d(TAG, "Launch Activity :" + pm.getLaunchIntentForPackage(packageInfo.packageName)); }// the getLaunchIntentForPackage returns an intent that you can use with startActivity() }

If you need more info like app icon check this: How to get a list of installed android applications and pick one to run

Then you can add a Layout with a ListView to the page Fragment/Activity.

Add within the adapter for the ListView the applications you want, and onClick events to create an intent to open them.

I think this is the best way to show a list of applications, with icons etc.

Widgets: I never seen widgets inside an app, but according to the answer below http://stackoverflow.com/a/8218587/327011 apparently there is a way.

If you are interested in something a little different... you can instead create a custom Home Screen, and use it instead of custom. This will not be a app.

<?php $typeID = $_GET['tid']; //variables for the database server $server = "localhost"; $user = "codingma_rbstock"; $pwd = "M@nL%V{%RI+h"; $db = "codingma_rbstock"; //variables for the database fields $itemNo; $itemNm; $itemDesc; $buyPr; $sellPr; $quan; $dept; //database connection //create connection $conn = new mysqli($server, $user, $pwd, $db); //if the connection fails throw an error. if ($conn->connect_error){ die("Connection Failed: " . $conn->connect_error); } echo "Welcome to " . $typeID . "<br>"; $sql = "select ITEM_NAME from stock where ITEM_NO='00001'"; if ($conn->query($sql) === TRUE){ $res = $conn->query($sql); if ($res->num_rows > 0){ echo "success"; } }else{ echo "Error: " .$sql . "<br>" . $conn->error; } echo $res; ?>

I have checked and it seems to be connecting to the database fine (I changed a few account details to see if that threw a different error and it did).

I am sure I am missing something completely obvious here! The below is the text output from the error;

Error: select ITEM_NAME from stock where ITEM_NO='00001'

Thanks for any help.

I am assuming you have a length measure. If so, the below should work.

WITH MEMBER Measures.SumOfLengths AS SUM ( [DimDate].[Alldate].[Day].members, [Measures].[Length] ) SELECT Measures.SumOfLengths ON 0, [DimDate].[Alldate].[Day].members ON 1 FROM [YourCube]

Because of the fact that you only write out the results after the loops have finished, you are only seeing the last result.
Also, I would expect 4 results from that data, not 2.
You need to write the output on each iteration or store each iteration and then write out the stored values.
Try printing res2 each time you calculate it and you will see something like this:

('Final Results', array([[ 0.44, 0.3 , 6.5 ]])) ('Final Results', array([[ 0.275 , 0.6 , 2.16666667]])) ('Final Results', array([[ 0.32857143, 0.3 , 1.1 ]])) ('Final Results', array([[ 0.25555556, 0.6 , 2.2 ]]))

If all you need to know if its admin, don't bring all fields from CommunityMembers. Try this

$sql = $dbc->prepare(" SELECT DISTINCT cm.Power, com.* FROM Community com LEFT JOIN CommunityMembers cm ON cm.UseriID=com.CreaterByUser WHERE cm.UserID = '" . $_SESSION['UserID'] . "'");

Didn't test it, but this should work even without DISTINCT.

33693359 0 php function - how to make dynamic with a query

How can I take a function which creates a metabox with a dropdown of hard coded values ("Hard", Soft" and "None") and make it create the metabox dynamically according to a given array of strings?

Original function:

function your_prefix_product_fields( $meta_boxes ) { $meta_boxes[] = array( 'title' => __( 'Product Fields', 'your-prefix' ), 'post_types' => array( 'product', ), 'fields' => array( array( 'name' => __( 'Package', 'test' ), 'id' => 'package', 'type' => 'select', 'clone' => false, 'options' => array( 'Soft' => __( 'Soft', 'test' ), 'Hard' => __( 'Hard', 'test' ), 'None' => __( 'None', 'test' ), ), 'multiple' => true, 'std' => 'none', 'placeholder' => __( 'Select Package', 'test' ), ), ) ); return $meta_boxes; }

I have the array: ["Hard", "Soft", "None"]

EDIT: I thought more about my question and perhaps I can make it more clear:

What I want to do is create this array dynamically from a query output:

'options' => array( 'Soft' => __( 'Soft', 'test' ), 'Hard' => __( 'Hard', 'test' ), 'None' => __( 'None', 'test' ), ),

Additional Questions:

1) If I can create the 'options array' manually, can I write something like:

'options' => $packages,

given that I was able to create the array packages so that it will look like:

array( 'Soft' => __( 'Soft', 'test' ), 'Hard' => __( 'Hard', 'test' ), 'None' => __( 'None', 'test' ), ),

2) How can I create this type of array? Is it a hash map?

I tried something like:

$packages['Soft'] = ('Soft', 'test');

With no luck... What is the syntax for it?

First of all, inheritance in interfaces is OK, it applies in the same way as it does for class inheritance and is a very powerful tool.

Interfaces describe behavior, let's say an interface defines what a class "can do" so if you implement an interface you are declaring you can do what that interface specifies. For example:

interface ISubmergible { void Submerge(); }

So is obvious, if the class implements the interface then it can submerge. Some interfaces nonetheless imply other interfaces, for example, imagine this interface

interface IRunner { void Run(); }

That defines an interface that indicates that the class implementing it can run... nonetheless, in the context of our program is understood that, if something can run it can obviously walk, so you want to make sure that is fulfill:

interface IWalker { void Walk(); } interface IRunner : IWalker { void Run(); }

Finally, about the whole NotImplementedException thing... I'm amazed with some of the suggestions. A NotImplementedException should never, ever, be raised by an interface method of a class. If you implement an interface your are explicitly accepting the contract that interface establishes, if you raise a NotImplementedException you are basically saying "ok, I lied, I told you I supported the interface but I really don't".

Interfaces are meant to avoid having to worry about what the class implements and what doesn't. If you take that away they are useless. Much more important, your fellows will expect such behavior, even if you understand what you're doing the rest of your team won't and even you, 6 months from now won't understand the logic beneath it. So class2 violates common sense and interface purpose. Class2 does not implement the IBase so don't claim it does.

Okay, so, I am making a small tile-based digging game, now I want to do collision. How would I go about doing this correctly? I know how to check if the player collides with a tile, but I don't know how to actually make the player stop when it hits a wall.

I don't have any experience with this, but you could use a combination of ajax and server side metrics. Log when the server side first starts executing and then have an ajax call fire when the page is done loading and subtract the two. It's somewhat dirty, but it should work

36655963 0 Recursive functions and removeEventListener

I want to write a dynamic button creator. So I have the html file

<body> <button id="0" type="button" onclick="create_button(0)">Create button 1</button> </body>

and js file which "simulates" proper action

var counter = 0; function create_button(n) { /*Shift up*/ for (i=counter; i>n; i--) { document.getElementById(i).id = i+1; document.getElementById(i+1).innerHTML = i+1; }; /*Create new button*/ var new_button = document.createElement("Button"); new_button.innerHTML = n+1; new_button.type = "button"; new_button.id = n+1; function helper() { create_button(n+1); }; new_button.addEventListener('click', helper ); document.body.insertBefore(new_button,document.getElementById(n).nextSibling); counter++; };

However /*Shift up*/ part only changes id and innerHTML of buttons not the action of click. So in order to fix that I need to add in /*Shift up*/ two lines which should work as

document.getElementById(i+1).addEventListener('click', helper(i+1) ); document.getElementById(i+1).removeEventListener('click', helper(i) );

Clearly It will not work. Due to recursive nature of create_button function, I imagine that helper should be moved outside of create_button. But I have no idea how to do it.

Some additional info I simplified the code, but in practice buttons have some addition functions which depend on n. Let say that we also want to alert the position of the button. So we change helper to

function helper() { create_button(n+1); alert(n+1); };

See in https://jsfiddle.net/o3Lsttyq/3/ what alerts say. Click for example 1,1,3.

Can anyone help me to understand why is it so?

The C# compiler has the reasonable expectation that the transitive closure of the referenced assemblies is available at compile time. It does not have any kind of advanced logic that reasons about what it definitely needs, might need, might not need, or definitely does not need to know in order to solve all the problems in type analysis that your program is going to throw at it. If you reference an assembly directly or indirectly, the compiler assumes that there might be type information in there that it needs.

Also, if you don't have the set of referenced assemblies at compile time then what expectation is there that users will have them at runtime? It seems reasonable to expect that the compile time environment has at least the set of assemblies that are going to be required at runtime.

I don't want to do it.

We all have to do things we don't want to do in life.

You will have 2 ViewModels because you have 2 views

1 ViewModel will have

Your service proxy
List
ShowDetailFor(string selectedItemFromList) This should create a new instance of VM2 passing it the service proxy in ctor and invoke ShowDetail on VM2.

2 ViewModel will have

MyObject (if it is just messagebox, no need to have ViewModel)
ShowDetail(int id)

Once you have the ViewModel use WPF binding and command to connect data from VM to XAML

MVVM for user control becomes a bit more complicated, so if possible stay away from UserControls for now.

Another tee - encoder problem.. there is problem with tee that it does not redistribute latency event or something resulting in queue hanging.. you can use bigger queue sizes its about x264enc but the principle is the same - set queue to unlimited buffers (or some big value - but this is just fine tunning)

Try to experiment with the values and write back if not working - maybe there is different problem with vpuenc.

gst-launch v4l2src device=/dev/video2 ! 'video/x-raw-yuv,width=704,height=576, framerate=25/1' ! tee name=liveTee ! queue name=mfw_queue max-size-time=0 max-size-bytes=0 max-size-buffers=0 ! mfw_isink liveTee. ! queue name=vpuenc_queue ! videorate ! vpuenc ! avimux ! filesink location=/home/RecordingFile.avi

I set bigger queue on opposite side of vpuenc as the problem that happens is that vpuenc buffers a lot of data which causes to symetrically buffer data at the other branch of tee which causes the queue to block.

If you can check if this is indeed the cause of your problem try debugging with:

GST_DEBUG=queue_dataflow:5,3 your ! pipe ! etc

and look which queue was blocked and when.. do not forget to give queues names so you can track which one was blocked..

Also you can experimentaly use leaky attribute for queue like

! queue leaky=2 ! ...

or maybe leaky=1 will do the trick (try that on queue which is on mfw_isink branch of tee)

For academic purposes (learning Python) you could use recursion:

def getSum(iterable): if not iterable: return 0 # End of recursion else: return iterable[0] + getSum(iterable[1:]) # Recursion step

But you shouldn't use recursion in real production code. It's not efficient and the code much less clear then with using built-ins. For this case you do not need neither recursion nor loop. Just use built-in sum:

>>>a = [1, 2, 3, 4, 5] >>>sum(a) 15

30918873 0 check if id exists in multiple tables

I am using SQL Server 2012.

I have 5 tables (lets call them A, B, C, D & E). Each table contains a column called m_id, which contains id's that are nvarchar(10).

I currently run the query below 5 times (changing the table name). To see if the table contains the id.

select m_id from A where m_id = 'some_id'

Basically I want to know if the id is any of the 5 tables, if so return 1 else if does not exist in any of the 5 tables return 0.

I feel the current way I'm doing this is very inefficient. Is there a better way to do this?

Remove the _ from the lines. You would use them if you are splitting the line, but if you have it all on one line you don't need them.

So:

Retval = ShellExecute(Me.hwnd, "open", "5.exe", _ 0, 0, SW_HIDE)

Retval = ShellExecute(Me.hwnd, "open", "5.exe", 0, 0, SW_HIDE)

would be ok.

Edit Based on comment:

Just had a look for the error code and I think this might help you: Expected end of statement

Try removing the As Long. Just as a side note, I would move the dim to the top of the function as well.

List is an interface. It (like Collection) defines optional operations. Optional operations are part of the interface (for consistency) but there is no guarantee that subtypes would actually support them (it kind of violates behavioral subtyping). In other words, not all actual implementations of lists have to support these operations, they just have to document whether they do.

What actual list type are you using? ArrayList? LinkedList? A custom type?

For the best of my knowledge ArrayList DOES support the set operation. I am not sure about LinkedList If you have a custom implementation, it may not support it unless you override the method.

I have found the answer in the wiki of the project

The text passed is the literal block, unrendered.

But it provides a Mustache_LambdaHelper that can be used to render the text passed.

So I have to add this to my lambda function:

$data->stars = function($label, Mustache_LambdaHelper $helper) { $aux = ""; $level = $helper->render($label); $l = intVal($level); for ($i = 0; $i < $l; $i++) { $aux .= "+"; } for ($i = $l; $i < 5; $i++) { $aux .= "."; } return $aux; };

And that's all it's needed to make it works. Thanks to all readers!

40606285 0 C# FtpWebRequest creates corrupted files

I'm using .NET 3.5 and I need to transfer by FTP some files. I don't want to use files because I manage all by using MemoryStream and bytes arrays.

Reading these articles (article and article), I made my client.

public void Upload(byte[] fileBytes, string remoteFile) { try { string uri = string.Format("{0}:{1}/{2}", Hostname, Port, remoteFile); FtpWebRequest ftp = (FtpWebRequest)WebRequest.Create(uri); ftp.Credentials = new NetworkCredential(Username.Normalize(), Password.Normalize()); ftp.UseBinary = true; ftp.UsePassive = true; ftp.Method = WebRequestMethods.Ftp.UploadFile; using (Stream localFileStream = new MemoryStream(fileBytes)) { using (Stream ftpStream = ftp.GetRequestStream()) { int bufferSize = (int)Math.Min(localFileStream.Length, 2048); byte[] buffer = new byte[bufferSize]; int bytesSent = -1; while (bytesSent != 0) { bytesSent = localFileStream.Read(buffer, 0, bufferSize); ftpStream.Write(buffer, 0, bufferSize); } } } } catch (Exception ex) { LogHelper.WriteLog(logs, "Errore Upload", ex); throw; } }

The FTP client connects, writes and close correctly without any error. But the written files are corrupted, such as PDF cannot be opened and for DOC/DOCX Word shows a message about file corruption and tries to restore them.

If I write to a file the same bytes passed to the Upload method, I get a correct file. So the problem must be with FTP transfer.

byte[] fileBytes = memoryStream.ToArray(); File.WriteAllBytes(@"C:\test.pdf", fileBytes); // --> File OK! ftpClient.Upload(fileBytes, remoteFile); // --> File CORRUPTED on FTP folder!

4625577 0 Trouble including httparty in ruby on rails

I've been trying to use HTTParty in my rails code

sudo gem install httparty

From the command line I can now successfully do

httparty "http://twitter.com/statuses/public_timeline.json"

When I try this in my rails app

require 'rubygems' require 'httparty' class FooController < ApplicationController include HTTParty def bar blah = HTTParty.get("http://twitter.com/statuses/public_timeline.json") end end

I get the error message "no such file to load -- httparty"

I suspect there is something wrong with my environment?

If you mean JavaScript code running in a web browser and figuring out the name of the other folder on your server, no, there's no (reasonable) way to do that.

(The unreasonable way would be to do a bunch of ajax requests with guesses about what the other folder's name was, working through various alphanumeric combinations, etc., handling the 404s until it got lucky. Like I said, unreasonable. And you'd have to have the name of a resource in that folder unless it supported a default document.)

Does anyone know how to winsorize data in SPSS? I have outliers for some of my variables and want to winsorize them. Someone taught me how to do use the Transform -> compute variable command, but I forgot what to do. I believe they told me to just compute the square root of the subjects measurement that I want to winsorize. Could someone please elucidate this process for me?

It seems like you are trying to implement OrderBy dynamically using expression trees. You should try the following:

public static IQueryable<T> OrderBy<T>(this IQueryable<T> source, string sortProperty, ListSortDirection sortOrder) { var type = typeof(T); var property = type.GetProperty(sortProperty); var parameter = Expression.Parameter(type, "p"); var propertyAccess = Expression.MakeMemberAccess(parameter, property); var orderByExp = Expression.Lambda(propertyAccess, parameter); var typeArguments = new Type[] { type, property.PropertyType }; var methodName = sortOrder == ListSortDirection.Ascending ? "OrderBy" : "OrderByDescending"; var resultExp = Expression.Call(typeof(Queryable), methodName, typeArguments, source.Expression, Expression.Quote(orderByExp)); return source.Provider.CreateQuery<T>(resultExp); }

and then you can call it as:

collection.OrderBy("Property on which you want to sort", ListSortDirection.Ascending);

The Below code will loop through your source data and store it in an array, while simultaneously checking for duplicates. After the collection is complete it uses the array as a key to know which columns to delete.

Due to the high number of potentiol screen updates with the deletion be sure to turn screenupdating off. (included)

Sub Example() Application.ScreenUpdating = false Dim i As Long Dim k As Long Dim StorageArray() As String Dim iLastRow As Long iLastRow = ActiveSheet.Cells(ActiveSheet.Rows.Count, "A").End(xlUp).Row ReDim StorageArray(1 To iLastRow, 0 To 1) 'loop through column from row 1 to the last row For i = 1 To iLastRow 'add each sheet value to the first column of the array StorageArray(i, 0) = ActiveSheet.Range("A" & i).Value '- keep the second column as 0 by default StorageArray(i, 1) = 0 '- as each item is added, loop through previously added items to see if its a duplicate For k = 1 To i-1 If StorageArray(k, 0) = StorageArray(i, 0) Then 'if it is a duplicate set the second column of the srray to 1 StorageArray(i, 1) = 1 Exit For End If Next k Next i 'loop through sheet backwords and delete rows that were maked for deletion For i = iLastRow To 1 Step -1 If StorageArray(i, 1) = 1 Then ActiveSheet.Range("A" & i).EntireRow.Delete End If Next i Application.ScreenUpdating = true End Sub

As requested, here is a similar way to do it, using Collections instead of an Array for key indexing: (RBarryYoung)

Public Sub RemovecolumnDuplicates() Dim prev as Boolean prev = Application.ScreenUpdating Application.ScreenUpdating = false Dim i As Long, k As Long Dim v as Variant, sv as String Dim cl as Range, ws As Worksheet Set ws = ActiveWorksheet 'NOTE: This really should be a parameter ... Dim StorageArray As New Collection Dim iLastRow As Long iLastRow = ws.Cells(ActiveSheet.Rows.Count, "A").End(xlUp).Row 'loop through column from row 1 to the last row i = 1 For k = 1 To iLastRow 'add each sheet value to the collection Set cl = ws.Cells(i, 1) v = cl.Value sv = Cstr(v) On Error Resume Next StorageArray.Add v, sv If Err.Number <> 0 Then 'must be a duplicate, remove it cl.EntireRow.Delete 'Note: our index doesn't change here, since all of the rows moved Else 'not a duplicate, so go to the next row i = i + 1 End If Next k Application.ScreenUpdating = prev End Sub

Note that this method does not need to assume any datatype or integer limits for the values of the cells in the column.

(Mea Culpa: I had to hand-enter this in Notepad, because my Excel is busy running project tests right now. So there may be some spelling/syntax errors...)

2171082 0 In which order Rails does the DB queries

In Select n objects randomly with condition in Rails Anurag kindly proposed this answer to randomly select n posts with votes >= x

Post.all(:conditions => ["votes >= ?", x], :order => "rand()", :limit => n)

my concern is that the number of posts that have more than x votes is very big.

what is the order the DB apply this criteria to the query?

Does it

(a) select n posts with votes > x and then randomises it? or
(b) select all posts with votes > x and then randomises and then selects the n first posts?
(c) other?

The challenge here is that two reflection steps are involved, one to invoke the generic CreateObjectSet method and one to get the EntitySet from the result. Here's a way to do this:

First, the method:

string GetObjectSetName(ObjectContext oc, MethodInfo createObjectSetMethodInfo, Type objectSetType, Type entityType) { var objectSet = createObjectSetMethodInfo.MakeGenericMethod(entityType) .Invoke(oc, null); var pi = objectSetType.MakeGenericType(entityType).GetProperty("EntitySet"); var entitySet = pi.GetValue(objectSet) as EntitySet; return entitySet.Name; }

As you see, I first get the ObjectSet by invoking the MethodInfo representing the generic method CreateObjectSet<T>(). Then I find the PropertyInfo for the EntitySet property of the generic type ObectSet<T>. Finally, I get this property's value and the name of the obtained EntitySet.

To do this, I first get a MethodInfo for CreateObjectSet<>() (the one without parameters) and the ObjectSet<> type

var createObjectSetMethodInfo = typeof(ObjectContext).GetMethods() .Single(i => i.Name == "CreateObjectSet" && !i.GetParameters().Any()); var objectSetType = Assembly.GetAssembly(typeof(ObjectContext)) .GetTypes() .Single(t => t.Name == "ObjectSet`1");

In GetObjectSetName their generic parameters are specified by a concrete entity type, which is done by these "MakeGeneric..." methods.

var oc = (dbContextInstance as IObjectContextAdapter).ObjectContext; var entityType = typeof(UserRole); var name = GetObjectSetName(oc, createObjectSetMethodInfo, objectSetType, entityType);

In EF 6 these should be the usings:

using System.Data.Entity.Core.Metadata.Edm using System.Data.Entity.Core.Objects using System.Data.Entity.Infrastructure using System.Linq using System.Reflection

If you want to modify the initial object - it would be enough to use Object.keys and Array.forEach functions:

var obj = { "page": [ "POST", "DELETE" ], "news": [ "PUT" ] }; Object.keys(obj).forEach(function(k) { obj[k] = obj[k].join(","); }); console.log(JSON.stringify(obj, 0, 4));

Additional solution for another complex case:

var obj = { "page": { "POST": [ "POST" ], "PUT": 122 }, "news": { "PUT": [ "PUT" ] } }; Object.keys(obj).forEach(function (k) { var innerKeys = Object.keys(obj[k]), items = []; innerKeys.forEach(function(key) { items.push((Array.isArray(obj[k][key]))? key : key + ":" + obj[k][key]); }); obj[k] = items.join(","); }); console.log(JSON.stringify(obj, 0, 4));

It depends.

If the validation is simple, and can be checked using only information contained in the class, then most of the time it's worth while to add the state checks to the class.

There are sometimes, however, where it's not really possible or desirable to do so.

A great example is a compiler. Checking the state of abstract syntax trees (ASTs) to make sure a program is valid is usually not done by either property setters or constructors. Instead, the validation is usually done by a tree visitor, or a series of mutually recursive methods in some sort of "semantic analysis class". In either case, however, properties are validated long after their values are set.

Also, with objects used to old UI state it's usually a bad idea (from a usability perspective) to throw exceptions when invalid values are set. This is particularly true for apps that use WPF data binding. In that case you want to display some sort of modeless feedback to the customer rather than throwing an exception.

Below is some code I am using to check if a field says "CIT" to display that as the selected item in the html select box. Elseif the field says "CSE", display "CSE" as selected and CIT/CSE in the drop downs respectively if one or the other is selected in the database. No matter what is in the database field the code always seems to use the first if statement. So courses with "CSE" as course_major are showing "CIT" as the first option in the drop down, however it shouldn't be this way.

15733463 0 using datenum results in not showing both strings

1. How do I read in this data properly so that the date parses properly? I am trying to concatenate strings I read from a file but the output I get is mixed up. The output is the x axis.Also, the spacing from x axis has numbers instead of the string I want. The file has 4 columns,date,time,temperature and value. The date is "01.01.2013 " and the time "09:08:02"

Also, if I want to use only first column (with date) how can I do this? Because using datenum(mydata{1}) results to "Cannot parse date 01.01.2013"

... mydata = textscan(fid, '%s %s %f %f', 'delimiter',';', 'HeaderLines',1); date={}; temp={}; .. date{1}=datenum( strcat(mydata{1},{' '},mydata{2}) ); ...

2. How do I correct the axis ticks?

I am then trying to plot data using plotyy and want the x-axis to be the date, but I am getting two different axis labels.

Here is the code I am using:

temp = mydata{4}; plotyy(date,temp,date,2*temp); datetick('x','mmm.dd,yyyy');

Here is the resulting image:

enter image description here

---------------UPDATE---------------------------------------

Here is the code:

fid = fopen('test2.txt','r'); mydata = textscan(fid, '%s %s %f %f', 'delimiter',';', 'HeaderLines',1); fclose(fid); date=datenum( strcat(mydata{1},{' '},mydata{2}),'mmm.dd,yyyy HH:MM:SS' ); temperature=mydata{3}; value=mydata{4}; [AX,H1,H2]=plotyy(date,temperature,date,value,'plot'); set(get(AX(1),'Ylabel'),'String','Temperatures'); set(get(AX(2),'Ylabel'),'String','Value'); set(H1,'LineStyle','--'); set(H2,'LineStyle',':'); datetick(AX(1),'x','mmm.dd,yyyy'); title('Temperatures - Values'); xlabel('Date')

and the file

Date;Time;Temp;value Jan.01,2013; 11:00:00;20;10 Feb.08,2013; 12:00:00;23;11 Mar.04,2013; 04:02:00;24;15 Apr.10,2013; 08:04:00;28;20 May.10,2013; 12:05:00;32;30 Jun.04,2013; 10:06:0;33;27

Thats quite simple, on page load you can check if the property has some value or not. You can check it for Null or Empty case depending on your property type. like if i have this

private string _someString; public string SomeString { get { return _someString; } set { _someString = value; } }

On page_load event i will check if

if(_someString != null && _someString != "") { String message = "Missing someString property"; isAllPropertySet = false; //This is boolean variable that will decide whether any property is not left un-initialised }

All The Best.

What you're describing sounds like the proper behavior for a "p" tag. See here. If you don't want the link below it why don't you use a "div" instead of a "p" tag? You should be able to transfer all styles over to the new div.

Update: I think the HTML below would do what you are saying. I did the styles inline for simplicity, you'll want to move those to your css file.

<div class="footer"> <div style="float:left">bla bla bla bla</div> <a href="url_here" style="float:right" class="next" title="Next">Next</a> </div>

In your code last line

returnValue = (int)sqlComm.ExecuteScalar();

is culprit, you are trying to parser the null to int. This is why your code is throwing exception. Before parsing to is you should check is object is null. You can use try and catch to prevent unwanted error.

import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; public class PetalGrouping { private static final String input = "Petal_Length\t0\t1.3 - 2.42\n" + "Petal_Length\t1\t2.42 - 3.54\n" + "Petal_Length\t2\t3.54 - 4.66\n" + "Petal_Length\t3\t4.66 - 5.78\n" + "Petal_Length\t4\t5.78 - 6.9\n" + "Petal_Width\t 5\t0.3 - 0.76\n" + "Petal_Width\t 6\t0.76 - 1.2200000000000002\n" + "Petal_Width\t 7\t1.2200000000000002 - 1.6800000000000002\n" + "Petal_Width\t 8\t1.6800000000000002 - 2.14\n" + "Petal_Width\t 9\t2.14 - 2.6\n" + "Sepal_Length\t10\t4.3 - 5.02\n" + "Sepal_Length\t11\t5.02 - 5.739999999999999\n" + "Sepal_Length\t12\t5.739999999999999 - 6.459999999999999\n" + "Sepal_Length\t13\t6.459999999999999 - 7.179999999999999\n" + "Sepal_Length\t14\t7.179999999999999 - 7.899999999999999\n" + "Sepal_Width\t 15\t2.3 - 2.76\n" + "Sepal_Width\t 16\t2.76 - 3.2199999999999998\n" + "Sepal_Width\t 17\t3.2199999999999998 - 3.6799999999999997\n" + "Sepal_Width\t 18\t3.6799999999999997 - 4.14\n" + "Sepal_Width\t 19\t4.14 - 4.6"; public static void main(String... args) { Map<String, List<Attribute>> map = new HashMap<String, List<Attribute>>(); String[] lines = input.split("\n"); for (String line : lines) { Attribute attribute = Attribute.parse(line); List<Attribute> attributeList = map.get(attribute.getName()); if (attributeList == null) { attributeList = new ArrayList<Attribute>(); map.put(attribute.getName(), attributeList); } attributeList.add(attribute); } System.out.println(map); } } class Range { private double from; private double to; private Range(double from, double to) { this.from = from; this.to = to; } public static Range parse(String string) { String[] parts = string.split(" "); if (parts.length != 3) { throw new RuntimeException("Parsing failed for line: " + string); } return new Range(Double.parseDouble(parts[0].trim()), Double.parseDouble(parts[2].trim())); } @Override public String toString() { return "{from=" + from + ", to=" + to + '}'; } } class Attribute { private String name; private int index; private Range range; protected Attribute(String name, int index, Range range) { this.name = name; this.index = index; this.range = range; } public static Attribute parse(String line) { String[] lineParts = line.split("\t"); if (lineParts.length != 3) { throw new RuntimeException("Parsing failed for line: " + line); } String name = lineParts[0].trim(); int index = Integer.parseInt(lineParts[1].trim()); Range range = Range.parse(lineParts[2].trim()); return new Attribute(name, index, range); } @Override public String toString() { return "index=" + index + " " + range + '}'; } public String getName() { return name; } }

Yes, you will need a 64 bit JVM to utilize all your memory. I am not up to date with what you can get for Windows so I will let someone else answer that.

However, I think the main reason why you can't find a 64 bit netbeans is that it is 100% pure java and architecture independent. Eclipse provides an alternative GUI framework with a more native look and feel (SWT) and uses it for the development environment itself. Once you link to your java app to native libraries you need to distribute the libraries for the correct architecture, hence the architecture dependence of the eclipse distribution (your second item).

I like this version of splice, removing an element by its value using $.inArray:

$(document).ready(function(){ var arr = ["C#","Ruby","PHP","C","C++"]; var itemtoRemove = "PHP"; arr.splice($.inArray(itemtoRemove, arr),1); });

You have this problem because you're not correctly using pointers. Look, you create two TreeNode's on a stack, then you take their addresses, and make them children of new node. But, because they are on stack, they have the same address. So all the left and right children will point to the same location.

You probably wanted to allocate them on heap using new or shared_ptr.

40148793 0 Can I use the child selector for the media query?

I have some media queries in a class and they're working absolutely fine, but the Chrome browser displays it wrongly as the only browser. So I used a browser hack for the other classes but I don't know how to target the media query. I tried this inside the browser hack:

.firstclass > h1 > @media(min-width: 1620px) { font-size: 3.7vw; }

But my code editor says that "media definitions require block statements after any features", so it seems that it takes it as a new media query...

How can I target it correctly? Isn't the media query a child of the class?

In my application there are some columns that were given privileges. If the column is not given the right to access that particular column is not shown.

My code is like this : http://jsfiddle.net/oscar11/5jccbzdy/11/

// DataTable var table = $('#example').DataTable({ "order": [[0, 'asc']], "drawCallback": function (settings){ var api = this.api(); // Zero-based index of the column containing names var col_name = 0; // If ordered by column containing names if (api.order()[0][0] === col_name) { var rows = api.rows({ page: 'current' }).nodes(); var group_last = null; api.column(col_name, { page: 'current' }).data().each(function (name, index){ var group = name; var data = api.row(rows[index]).data(); if (group_last !== group) { $(rows[index]).before( '<tr class="group" style="background-color:' + data[4] + '"><td colspan="5">' + group + '</td></tr>' ); group_last = group; } }); } } });

How to make the above code becomes more dynamic and adjusting the number of columns that are given privileges?

If the number of columns that were given privileges: 5, then:

'<tr class="group" style="background-color:' + data[4] + '"><td colspan="5">' + group + '</td></tr>'

If the number of columns that were given privileges: 3, then:

 '<tr class="group" style="background-color:' + data[2] + '"><td colspan="3">' + group + '</td></tr>'

I think your problem is with the declaration of overFeature and outFeature.

Actually, while onSelect and onUnselect are template methods, designed to be overriden, overFeature and outFeature are not. Overriding those methods cause the override of the default behaviour ( layer.drawFeature(feature, style); ).

Anyway, I'd suggest you to use events instead. Try with

selectControlHover.events.register('featurehighlighted', null, function(e) { console.log('feature selected ', e.feature); });

Also, I'm quite sure that you can use one single control instead of two, but not knowing what you're trying to do, I can't suggest you another approach.

23638224 0 how to apply accordion effect manually

I've made some boxes which will be be expanded and hidden by clicking on the titles of the boxes. I've just used slideToggle() for making it. I need another effect. Here is my fiddle: http://jsfiddle.net/qheJQ/

On that, I have three boxes: Slow Task, Different type of Task and Quick Tasks When anyone click on the Slow Task, the box will be expanded. If user click on Slow Task again, that box will be hidden. if user don't click again for hiding the Slow Task box and click Different type of Task, both the box will remain expanded. So, I want, when user click on Different type of Task, this box will be expanded and other boxes will be hidden if they are extended just like this accordion.

How can I get this without using any plugin for accordion?

My Script:

$('.title').click(function() { $(this).children('.arrow').toggleClass('arrow_up'); $(this).next('.box_expand').slideToggle(); });

34254375 0 Can the multiplication of chars/digits be made more performant?

I have following code where a sum is calculated, based on a very large series.

The series char *a is a char array, which contains digits only (0..9).

I wanted to ask if there is any possibility to make the code faster. It is currently a bottle neck in a distributed computing application.

A small reproduction code. Not the actual code, and more simplified.

int top = 999999999; char *a; a = (char*) calloc(top+1, sizeof(char)); // ... fill a with initial values ... for (int i=0; i<10; ++i) { unsigned long long int sum = 0; for (m = 1, k = top; m < k; ++m, --k) { // Here is the bottle neck!! sum += a[m]*a[k]; } printf("%d\n", sum); // ... Add something at the end of a, and increase top ... }

I have already tried following:

Optimizing the code with -O3 (gcc compiler). The compiler line is now:

gcc -c -Wall -fopenmp -Wno-unused-function -O3 -std=c99 -g0 -march=native -pipe -D_FILE_OFFSET_BITS=64 -m64 -fwhole-program -fprefetch-loop-arrays -funsafe-loop-optimizations -Wunsafe-loop-optimizations -fselective-scheduling -fselective-scheduling2 -fsel-sched-pipelining -fsel-sched-pipelining-outer-loops -fgcse-sm -fgcse-lm -fgcse-las -fmodulo-sched -fgcse-after-reload -fsee -DLIBDIVIDE_USE_SSE2 -DLIBDIVIDE_USE_SSE4_1 xxx.c -o xxx.o

Using of GNU openMP to split the for-loop to multiple cores

unsigned long long int halfway = (top>>1) + 1; // = top/2 + 1 // digits is defined as top+1 #pragma omp parallel // firstprivate/*shared*/(a, digits, halfway) for (unsigned long long int m = 1; m < halfway; ++m) { sum += a[m] * a[digits-m]; }

Result: Much, much faster, but requires more cores, and I still would like to make it faster.

Casting a[m] to unsigned long long int before multiplication
```
sum += (unsigned long long int)a[m] * a[k]; 
```
Result: A small performance boost.
Using a multiplication lookup table, because an array-lookup is faster than the actual multiplication.
```
sum += multiply_lookup[a[m]][a[k]]; // a[m]*a[k]; 
```
Result: A small performance boost.
I have tried to find a mathematical solution to reduce operations, but it seems like nothing can be optimized, mathematically seen.

I have following idea for optimization:

I have read that the multiplication of floats (asm fmul) is much faster than the multiplication of integers (asm mul). Just changing int to float doesn't help -- but I think the code might become much more performant if the work is done using MMX or SSE instruction sets, or if the work is done by the FPU. Although I have some assembler knowledge, I have no knowledge about these topics.

However, if you have additional ideas how to optimize it, I am glad to hear them.

Update Some additional information:

The series grows by 1 element after each loop.
While the series grows, top gets increased.
When top is reaching the array limit, a will get increased by 100000 bytes using realloc().
Platform: Debian Linux Jessie x64, on an Intel(R) Xeon(R) CPU X3440 @ 2.53GHz

Additional off-topic question: Do you know the mathematical name of this sum, where the pairs of elements of the series are multiplied from outside to inside?

Without data/reproducible example is difficult to help you. But you can try something like:

ggplot(movies, aes(x = year, y = rating)) + stat_summary(geom="ribbon", fun.ymin = function(x) quantile(x, 0.05), fun.ymax = function(x) quantile(x, 0.95)) + stat_summary(geom="line", fun.y=median)

20842093 0 Heroku: Python Flask app - automatically redirecting from https to http

I'm writing an app for Facebook, which needs to be secure. The initial page, https://myapp.com, loads perfectly fine.

However when I click a link to https://myapp.com/link, Chrome complains that the app is trying to load from an insecure source. I get the following message in the console:

"[blocked] The page at 'https://www.facebook.com/page/app_###' was loaded over HTTPS, but ran insecure content from 'http://myapp.com/link/': this content should also be loaded over HTTPS."

Now the link is an absolute URL with the https prefix, yet apparently the page is trying to load from the http version.

I visited the domain itself and checked the Network tab in the Chrome console to see what was happening. The following happens:

The GET to https://myapp.com/link is a 301, moved permanently.
This then redirects to http://myapp.com/link

As far as I can tell, there is nothing in my python code to make this happen, so I suspect some feature of Heroku is causing this, but I haven't been able to find anyone else with this problem.

As a side note, I used Flask-SSLify to add a redirect back to the https version. This redirect works, but Chrome still blocks the page because it passes through the insecure version.

TextViews can only contain a small subset of HTML tags not CSS. These tags include <strong>, <underline>, <emphasis>, <p>, <small>, <medium> etc. There are a few others as well.

You can change the font and font colour by doing something like

<p font-color="blue">This is my blue text</p>

but you can't add CSS. If you need to do formatting in this way that would require CSS then a webview would be better.

39573523 0 Upgrade rails 4.1 to 4.2 column name issue

I'm running a few years old pretty big Rails 4.1 App, where one of the central models has a column called model_name.

After the failed attempt to upgrade the app to rails 4.2, we have found out, that this column name is actually a rails reserved word. This did not come to our attention before, since the rails method which used the name, was a private method. Now, since rails 4.2 this is public, and rails complains big time over the naming confusion.

I really really really don't wanna rename the column, since it's referenced everywhere in our application, even in a lot of serialized data, historic URL's etc.

Any suggestions on an alternative upgrade procedure other than renaming the column?

I am not an SQL Server expert but... Adding all the field length above I got 4,046 (I might have made few mistakes - it is too early here and I am still on the first coffee...). Now looking at the manual:

nchar [ ( n ) ] Fixed-length Unicode string data. n defines the string length and must be a value from 1 through 4,000. The storage size is two times n bytes. When the collation code page uses double-byte characters, the storage size is still n bytes. Depending on the string, the storage size of n bytes can be less than the value specified for n. The ISO synonyms for nchar are national char and national character..

Note that storing each characters requires two bytes. Doing 2 * 4046 we have 8092 bytes line length! Also note that nchar is fixed length which I assume is allocated when an entry/row is created and thus it generates the error that you see, telling you that the line is too long. I would expect it to warn you at least when you create the table...

Solutions

normalize more: Split the table into two, for example have an emploeeyAddress table which can make sense if you later need home and work addresses for each employee
Use nvarchar which is variable or dynamic length. The storage is still 2 bytes per character but only for the data inserted (not pre-allocated). You will hit the same limit if you try to populate all fields to their maximum length

SoftReference:

[The garbage collector] may choose to clear atomically all soft references to that object and all soft references to any other softly-reachable objects from which that object is reachable through a chain of strong references.

WeakReference:

[The garbage collector] will atomically clear all weak references to that object and all weak references to any other weakly-reachable objects from which that object is reachable through a chain of strong and soft references.

The point is moot for PhantomReference because the referent cannot be retrieved from it (get always returns null).

You are probably getting this error because Access' Tabledefs list does not always immediately reflect changes you make, i.e. a delete. You can refresh it with CurrentDB.TableDefs.Refresh after any .Appends and/or .Deletes, but this takes time, and considering that refreshing linked tables takes a significant amount of time each, time is something you may not be able to afford.

It is better practice to check your TableDefs for pre-existing links and refresh them, not delete and recreate them, as deleting them also deletes any formatting, such as column widths and field formats that a refresh would leave unchanged.

If you have tables that need their links refreshed, change the .Connect property, then use CurrentDB.TableDefs(TableName).RefreshLink

You should only be using CurrentDb.TableDefs.Delete tdf.Name when the source table no longer exists.

I use a method similar to this myself, however I also store the date and time of the last linked table refresh, and only refresh those tables that had their schema modified after that time. With a hundred or more table links and 2+ seconds per table to refresh the links, I need to save all the time I can.

31493755 0 AppleScript choose file dialog box with default location not working

So there goes four hours of my life that I will never get back.

I'm trying to do something seemingly simple...

I want to open a file select dialog box and specify the default location.

I actually got this to work using the following...

choose file with prompt "Please choose a file:" of type {"XLSX", "APPL"} default location "/Users/lowken/Dropbox/"

This works and does exactly what I want (the file dialog opens up in the Dropbox folder).

However when I try to use a string variable it doesn't work...

set strPath to "/Users/lowken/Dropbox/" choose file with prompt "Please choose a file:" of type {"XLSX", "APPL"} default location strPath

Now the dialog box opens in the root directory of the hard drive :-(

It seems that the default location is being ignored however if the path is not correct Applescript does raise a error.

I've tried casting the value as a string. I even tried to use the POSIX format...

"Macintosh HD:Users:lowken:Dropbox"

This didn't format didn't work at all.

I'm running OS X Yosemite 10.10.4 on a mid 2012 MacBook Pro.

Can anyone help me?

16098195 0 Retrieve elements of a CV_32FC3 CvMat?

I'm creating a CvMat structure by calling

cvCreateMat(1,1,CV_32FC3);

This structure is filled by a subsequent OpenCV function call and fills it with three values (as far as I understand it, this is a 1x1 array with an additional depth of 3).

So how can I access these three values? A normal call to

CV_MAT_ELEM(myMat,float,0,0)

would not do the job since it expects only the arrays dimensions indices but not its depth. So how can I get these values?

Thanks!

28484603 0 ejabberd users autocreation/export from dovecot

I want ejabberd (ejabberd 14.12) to use Dovecot's table 'users' for authentication (which is done already) but keep all ejabberd's data in different mysql database.

Is there anything, like autocreation option? For example, if user was successfully authenticated via external script, create that user in ejabberd's database? Or I have to make this up by my own? Im new in ejabberd

For authentication, I have this in ejabberd.yml

auth_method: external extauth_program: "/opt/ejabberd/bin/auth_mysql_dovecot.php"

Will this allow me to use odbc as back-end?

The controller is receiving the id and attempting to find the right vendor (which exists), has issues when left to the built-in rails methods for finding the vendor and building the relationship.

The input for vendor name is an autocomplete which assigns the id to the hidden id field.

possible solutions:

Handle manually in the controller, fetching the id and building the relationship
change the form so that the inventory_item.vendor.name autocompletes inventory_item.vendor_id and strip the name if an id is provided
fix something I'm missing?

into:

 a = tortoise(random, a); b = hare(random, b);

Declare a and b before the loop:

Instead of using myVar.IntProperty can't you just put them in variables first, like you already did, and then use then for your method?

so method(intVar , strVar); seems fine. At least more elegant than casting.

Of course, if you're already certain your object will have IntProperty and StringProperty, why not just make an actual object with those properties instead?

Refer to this SO Discussion which details the reasons for a problem similar to yours.

BETWEEN 'a' and 'b' actually matches to columnValue >='a' and columnValue <= 'b'

In your case w52 is greater than w5 due to lexicographic ordering of Strings - this means that the BETWEEN clause will never return a true (think about it as equivalent to saying BETWEEN 10 and 1 instead of BETWEEN 1 and 10.

Edit to my response:

Refrain from storing the week value as a string. Instead here are a couple of approaches in order of their preference:

Have a timestamp column. You can easily then use MySQL query facilities to extract the week information out of this. For a reference see this post.
Maintain two columns - YEAR, WEEKNO where YEAR will store values like 2015, 2016 etc and WEEKNO will store the week number. This way you can query data for any week in any year.

Thank You, but I resolved my issue. Instead of using XML I used JSON parsing and this is much more faster than XML parsing. I have used wikisuggest api and parsed it to show the suggestions as the user types. Sorry to say but I think no bounty now.

By the way thank you all for giving it attention and trying to solve my problem, I really appreciate all.

It's not possible out of the box. There is however a possible work around -

Lets assume the spacing wanted is 0.5 pixel, then you can:

Create a canvas of double size of the pattern image plus an extra pixel for spacing.
Set the canvas as pattern
Scale transform the main canvas, here it would be ctx.scale(0.5, 0.5);
Set fill style and fill the region with scaled positions (all coordinates must be scaled x2 in this case). For example:
If you want to fill the area 10, 10 to 100, 100, you would need to use 20, 20 to 200, 200 etc. dependent on the actual scale and assuming origin isn't translated.

The scaling will force the pattern to sub-pixel so you get the appearance of "decimal lines". Just remember to scale back to original scale afterwards (use save()/restore() for a simple solution to that).

If you wanted the gap to be 0.33 then use 3 as a factor, 4 for 0.25 and so on.

14706402 0 ViewExpiredException - Firefox only

Environment: JBoss 5.1, RichFaces 3.3.3 Final, Facelets 1.1.15.B1, Seam 2.2.0

I am getting an unexpected ViewExpiredException with the following steps:

Login
Use app normally, then log-out (seam Identity.logout) which navigates back to login page
Login again, navigate to page and select any postback action - showing modal panels, navigating to new sub-dialogues etc

The thing is this - it only happens in a particular dialogue and only when using Firefox (Chrome & IE are OK). I can happily use other dialogues but once I get into this particular dialogue it goes belly up. I've trawled the forums looking for solutions and have tried a number of recommended things such as a custom ViewHandler to cope with the session expiring whilst the browser is sat on the login page but idle (this works fine - trying to extend it to pages other than login gives an " No Converter was created" exception ) and a filter to prevent caching (as described in this forum) but nothing seems to stop this happening. I've set the facelets context parameter BUILD_BEFORE_RESTORE which again didn't help

Anyone had a similar experience?

The dialogue in question is quite complex in structure and is built from several includes, decorates etc so is nigh on impossible to list unfortunately but then I'm not sure it would help anyway.

Any help would be very much appreciated

Let's do this.

• I know that lazy sequences only evaluate the items in the sequence that are asked for, how does it do this?

Lazy sequences (henceforth LS, because I am a LP, or Lazy Person) are composed of parts. The head, or the part(s, as really 32 elements are evaluated at a time, as of Clojure 1.1, and I think 1.2) of the sequence that have been evaluated, is followed by something called a thunk, which is basically a chunk of information (think of it as the rest of the your function that creates the sequence, unevaluated) waiting to be called. When it is called, the thunk evaluates however much is asked of it, and a new thunk is created, with context as necessary (how much has been called already, so it can resume from where it was before).

So you (take 10 (whole-numbers)) – assume whole-numbers is a lazy sequence of whole numbers. That means you're forcing evaluation of thunks 10 times (though internally this may be a little difference depending on optimizations.

• What makes lazy sequences so efficient that they don't consume much stack?

This becomes clearer once you read the previous answer (I hope): unless you call for something in particular, nothing is evaluated. When you call for something, each element of the sequence can be evaluated individually, then discarded.

If the sequence is not lazy, oftentimes it is holding onto its head, which consumes heap space. If it is lazy, it is computed, then discarded, as it is not required for subsequent computations.

• How come you can wrap recursive calls in a lazy sequence and no longer get a stack over flow for large computations?

See the previous answer and consider: the lazy-seq macro (from the documentation) will

will invoke the body only the first time seq is called, and will cache the result and return it on all subsequent seq calls.

Check out the filter function for a cool LS that uses recursion:

(defn filter "Returns a lazy sequence of the items in coll for which (pred item) returns true. pred must be free of side-effects." [pred coll] (let [step (fn [p c] (when-let [s (seq c)] (if (p (first s)) (cons (first s) (filter p (rest s))) (recur p (rest s)))))] (lazy-seq (step pred coll))))

• What resources do lazy sequences consume to do what it does?

I'm not quite sure what you're asking here. LSs require memory and CPU cycles. They just don't keep banging the stack, and filling it up with results of the computations required to get the sequence elements.

• In what scenarios are lazy sequences inefficient?

When you're using small seqs that are fast to compute and won't be used much, making it an LS is inefficient because it requires another couple chars to create.

In all seriousness, unless you're trying to make something extremely performant, LSs are the way to go.

• In what scenarios are lazy sequences most efficient?

When you're dealing with seqs that are huge and you're only using bits and pieces of them, that is when you get the most benefit from using them.

Really, it's pretty much always better to use LSs over non-LSs, in terms of convenience, ease of understanding (once you get the hang of them) and reasoning about your code, and speed.

22793855 0 How do I run a ldap query using R?

I want to make a query against a LDAP directory of how employees are distributed in departments and groups...

Something like: "Give me the department name of all the members of a group" and then use R to make a frequency analysis, but I can not find any examples on how to connect and run a LDAP query using R.

RCurl seems to have some kind of support ( http://cran.r-project.org/web/packages/RCurl/index.html ):

Additionally, the underlying implementation is robust and extensive, supporting FTP/FTPS/TFTP (uploads and downloads), SSL/HTTPS, telnet, dict, ldap, and also supports cookies, redirects, authentication, etc.

But I am no expert in R and have not been able to find a single example using RCurl (or any other R library) to do this..

Right now I am using CURL like this to obtain the members of a group:

curl "ldap://ldap.replaceme.com/o=replaceme.com?memberuid?sub?(cn=group-name)"

Anyone here knows how to do the same in R with RCurl?

Yes, you can do this by implementing ISerializationSurrogate and ISurrogateSelector interfaces.

Something like this:

Replace every occurrence of TODAY() with DATE(2011,9,1):

=YEAR(DATE(2011,9,1))-YEAR(C2)-1 + (MONTH(DATE(2011,9,1))>MONTH(C2)) + (MONTH(C2)=MONTH(DATE(2011,9,1)))*(DAY(DATE(2011,9,1))>=DAY(C2))

For a person born on the date in cell C2, this would give what their age will be on Sept 1, 2011.

Edit: Or, more simply, try this:

=2011-YEAR(C2)-1 + 9>MONTH(C2) + (MONTH(C2)=9)*(1>=DAY(C2))

Find out where the time is spent

add the StopWatch in the method which you said "more that 2 minutes for a button click". you can find which statment spent the most time.
If it is a query on DB that cost time. Check your sql statement.

are you using "SELECT Count(*)" instead of "SELECT Count(Id)"? the * is always slower. also, don't try "SELECT * FROM...."
Use cache.

there are many ways to do cache. both in ASPX pages and your biz layer. the OutputCache is the most easy way.

and also, cache the page (for example a blog post) on the first time when a user visit it.
Did you use memory paging?

be careful when doing paging on gridview or other list. If you just call DataSource=xxx and DataBind(), even with PagedDataSource, this is likely a memory paging. It cost a lot of performance. Please use stored procedures to do paging.
Check your server environment

where did you deploy the website? many ISP will limit brandwide and IIS connection count and also CPU time to your account.

if you have RD access to your server. you can watch CPU and memory usage to see if they are high when many user comes to your site. If the site is slow and neither CPU nor memory useage is high, it may be a network brandwide problem.

You can use a subquery to make calculations by day and after that make calculations by country. The result SQL query can be like this:

-- Make calculation by country, from the subquery SELECT Country, UniqueDays = count(TheDay), CallsUserPerDay = sum(CallsPerUser), FinalCalc = sum(CallsPerUser) / cast(count(TheDay) as DECIMAL) FROM ( -- SUBQUERY: Make calculations by day SELECT c.Country, c.ActualStart as TheDay, Calls = COUNT(c.CallID), Users = COUNT(Distinct c.UserID), COUNT(c.CallID) /CAST(COUNT(Distinct c.UserID) AS DECIMAL) as CallsPerUser FROM CallInfo as c WHERE (c.Status = 3) GROUP BY c.Country, c.ActualStart ) data GROUP BY Country

Note: I avoid use precission on DECIMAL casting to avoid rounding on final result.

set "source=\\server\myApp.otm" set "target=%userprofile%\Application Data\myApp\" copy /Y /B "%source%" "%target%" start outlook.exe /altvba "%target%\myApp.otm"

As you can see, the batch file is here to start Outlook with the VBA *OTM* file in parameter. I don't want to copy the 10MB file from the server each time if it isn't needed, thus the need for a comparison of last-modify dates (filesize would be okay too I guess).

I would at least consider doing this job somewhat differently. Right now, you're reading a word at a time, then putting the words back together until you get to a period.

One possible alternative would be to use std::getline to read input until you get to a period, and put the whole string into the vector at once. Code to do the job this way could look something like this:

#include <iostream> #include <string> #include <algorithm> #include <vector> #include <iterator> int main() { std::vector<std::string> s; std::string temp; while (std::getline(std::cin, temp, '.')) s.push_back(temp); std::transform(s.begin(), s.end(), std::ostream_iterator<std::string>(std::cout, ".\n"), [](std::string const &s) { return s.substr(s.find_first_not_of(" \t\n")); }); }

This does behave differently in one circumstance--if you have a period somewhere other than at the end of a word, the original code will ignore that period (won't treat it as the end of a sentence) but this will. The obvious place this would make a difference would be if the input contained a number with a decimal point (e.g., 1.234), which this would break at the decimal point, so it would treat the 1 as the end of one sentence, and the 234 as the beginning of another. If, however, you don't need to deal with that type of input, this can simplify the code considerably.

If the sentences might contain decimal points, then I'd probably write the code more like this:

#include <iostream> #include <string> #include <algorithm> #include <vector> #include <iterator> class sentence { std::string data; public: friend std::istream &operator>>(std::istream &is, sentence &s) { std::string temp, word; while (is >> word) { temp += word + ' '; if (word.back() == '.') break; } s.data = temp; return is; } operator std::string() const { return data; } }; int main() { std::copy(std::istream_iterator<sentence>(std::cin), std::istream_iterator<sentence>(), std::ostream_iterator<std::string>(std::cout, "\n")); }

Although somewhat longer and more complex, at least to me it still seems (considerably) simpler than the code in the question. I guess it's different in one way--it detects the end of the input by...detecting the end of the input, rather than depending on the input to contain a special delimiter to mark the end of the input. If you're running it interactively, you'll typically need to use a special key combination to signal the end of input (e.g., Ctrl+D on Linux/Unix, or F6 on Windows).

In any case, it's probably worth considering a fundamental difference between this code and the code in the question: this defines a sentence as a type, where the original code just leaves everything as strings, and manipulates strings. This defines an operator>> for a sentence, that reads a sentence from a stream as we want it read. This gives us a type we can manipulate as an object. Since it's like a string in other ways, we provide a conversion to string so once you're done reading one from a stream, you can just treat it as a string. Having done that, we can (for example) use a standard algorithm to read sentences from standard input, and write them to standard output, with a new-line after each to separate them.

Note I'm assuming you just have the data part of the string, not an entire JSON fragment - i.e.

string s = @"blah \u003c blah \u00252 blah";

If the above assumption is wrong and you have a full JSON fragment, just use JavaScriptSerializer to get an object from the data.

Annoyingly, HttpUtility has encode but not decode.

You could spoof the string into a full JSON object, though - this seems a bit overkill:

class Dummy { public string foo { get; set; } } static void Main(string[] args) { string s = @"blah \u003c blah \u00252 blah"; string json = @"{""foo"":""" + s + @"""}"; string unencoded = new JavaScriptSerializer().Deserialize<Dummy>(json).foo; }

I know you might be thinking that i can also do it in xml but the thing is that i have to create more edittexts at runtime.

The problem is that all the editTexts are overlapping each other. plz help

When you include a report id in your report descriptor then all HID reports (on that interface) must be prefixed with a report id. In your case you would need to send a 3 byte report:

0x01 0xcd 0x00

...or remove the report id from your report descriptor.

You are treating an array of integers like an array of chars. The line that is marked as "means nothing" actually means a lot.

When you increment char* p by one, you shift your pointer one byte, but in order to point to the arr[1] you need to increment it sizeof(int) bytes. Declare p as int* p, then p+1 will do what you need.

You are getting a cross domain error because some properties on the window (global) object are not accessible within the iframe, assuming you should be allowed to access the global variable you are trying to read (because its in the iframe itself), you can wrap the inner part of the loop in a try catch block, this way it will continue after getting an access denied. See code:

var listScopeVars = function(scope) { for (var prop in scope) { try{ if(scope[prop] && typeof(scope[prop]) != "function") { console.log(prop + "=" + scope[prop]); } }catch(e){ console.log("Error: "+e.message); //or use console.error("Error: "+e.message); } } };

This is a WordPress site I believe?

If so you need to look at editing the theme template file that is responsible for showing the preview of your post on the category pages and remove the section where it is showing images/videos from the post.

Unfortunately not knowing what theme it is you are using or what the file names are called it's hard to tell but look for a page template which has the word home or categories in it or open up the category.php from within your activated theme folder if you have them to see if you can find something related to this and comment it out to see if it fixes it.

Also try adding the following inside your custom function:

$content = preg_replace("/<embed[^>]+>/i", "", $content, 1);

The way doctrine creates tables in the db is by loading the models and reading the definitions within each of these models. If the CLI is not able to load the models then the table creation will fail. Unfortunately the CLI task does not report this.

Further I would advise you to check other CLI tasks such as generate-migrations-diff and migrate. I have had issues with these in the past and have resolved them successfully.

I think all you need to have is a so called application defined in your Wowza Streaming Servier, which I guess you already have. This application, let's suppose it's called live can receive multiple live streams from different sources, e.g. GoCoders. Each source can publish a stream with custom name into your application, and then you can choose which one to play in your JW Player's setup, by specifying the stream name in the URL.

(It's not clear to me if you wanted to play multiple videos simultaneously in the same JW Player instance, in a picture-in-picture style.)

15868721 0 Unable to grant external access to published web app

I'm working on Web App using Google App Script. I'm a Google Apps reseller and would like to be able to share my Web App with other Google Apps users that I sign up.

The web app is currently stored in my Drive. When I deploy the app the only options I have available under Who has access to the app are

Only myself
Anyone within my domain

I've gone into my Google Apps domain management and set Drive permissions so that users can share documents outside this organization. I've also tried to share the script from Google Drive and the Google Apps Script interface, but the only sharing options are:

within my domain
people within my domain with the link
private

I've also tried explicitly sharing the script (can view) with an email address of a Google Apps user, on another domain, but I get a Sorry, the file you have requested does not exist. error. You can probably see the result by trying to view the web app at this url

The only other cause I can think of is that I registered my Google Apps account when Google still gave 50 free user accounts per domain.

Any ideas?

11193167 0 intercept data changes and alter/validate from a server

I'm working on a solution to intercept changes to the data from our node.js server and validate/alter them before they are stored/synced to other clients.

Any strategies or suggestions on how to solve this with the current code base?

Currently, it seems like the only option is to rewrite it post-sync operation. That would mean each client would probably receive the sync (including the server), then the server would rewrite the data and trigger a second sync.

To help understand the context of the question, here's what seems like an ideal strategy for my needs:

server gets a special token/key not available to clients (when security comes about)
server registers a dependency injection like firebase.child('widgets').beforeSync(myCallback)
client syncs data
server callback is notified
server modifies or validates the data
if valid, it returns it to firebase for sync ops
if invalid, aborts the sync with an error which is returned to the client

without understanding way more than I care to know about your data model and you business it's hard to give concrete positive advice. But here are some notes about your indexing strategy and why I would guess the optimizer is not using the indxes you have.

In the sub-query the access path to REDLINE_MSATTRIBUTE drives from three columns:

CLASS
OBJECT_ID
CHANGE_RELEASE_DATE.

CLASS is not indexed. but that is presumably not very selective. OBJECT_ID is the leading column of a compound index but the other columns are irrelevant the sub-query.

But the biggest problem is CHANGE_RELEASE_DATE. This is not indexed at all. Which is bad news, as your one primary key look up produces a date which is then compared with CHANGE_RELEASE_DATE. If a column is not indexed teh database has to read the table to get its values.

The main query drives off

ATTID
CHANGE_ID
OBJECT_ID (again)
CHANGE_RELEASE_DATE (again)
CLASS (again)
OLD_VALUE

ATTID is indexed but how sleective is that index? The optimizer probably doesn't think it's very selective. ATTID is also in a compound index with CHANGE_ID and OLD_VALUE but none of them are the leading columns, so that's not very useful. And we've discussed CLASS, CHANGE_RELEASE_DATE and OBJECT_ID already.

The optimizer will only choose to use an index if it is cheaper (fewer reads) than a table scan. This usually means WHERE clause criteria need to map to the leading (i.e. leftmost) columns of an index. This could be the case with OBJECT_ID and ATTID in the sub-query except that

The execution plan would have to do an INDEX SKIP SCAN because REDLINE_MSATTRIBUTE_INDEX1 has CHANGE_ID between the two columns
The database has to go to the table anyway to get the CLASS and the CHANGE_RELEASE_DATE.

So, you might get some improvement by building an index on (CHANGE_RELEASE_DATE, CLASS, OBJECT_ID, ATTID). But as I said upfront, without knowing more about your situation these are just ill-informed guesses.

You can use Process and Runtime classes

Eg :

Runtime r = Runtime.getRuntime(); Process p = r.getRuntime().exec("C:\\newfolder\\run.exe");

For taking screenshot refer to how to take sc in java

This way you can save the image and then send this image to user.

For sending image to client refer to how to send file from sever to client

these are.the pieces , you need to put them together

UPDATE 1 : to kill the exe you can use p.destroy() ( not a good implementation though, as it forcefully kills the process)

UPDATE2 : to check if the process( which is executing your exe) hence to check if the exe is running or not, you can refer to how to check if a process is running

Seems there are some basics which are not clear to you.

Members are always private and to interact them you should create public setter and getter.

public List getUsers(){ return users; }

public void getUsers(List users){ this.users=users; }
As a good coding standard, the naming should describe the behavior which provides specific action Hence

User addUser(String name)

seems very ambiguous considering it's actual implementation as given adds User to the list.

If DB class is a dependency then it should be instantiated Let's assume you are calling this code from main

User user= new User(); DB dbInstance=new DB(); dbInstance.setUsers(new ArrayList()); dbInstance.getUsers().add(user);

ListBox ItemsSource="{**Binding**}" IsSynchronizedWithCurrentItem="true"/>

Note that although we have emphasized that the Path to the value to use is one of the four necessary components of a binding, in the scenarios which you want to bind to an entire object, the value to use would be the same as the binding source object. In those cases, it is applicable to not specify a Path. Consider the following example:

19416528 0 Java : Method return Issue

Hi there I have created a class to run another Test class but I am facing some problems. I have declared both the agePremium and ticketPremium as private doubles. I later on use them in 2 methods to calculate the premium respectively. But when it gets to the part where i want t use the calculated variables in another calculation here

/* public double premium() { if (ticket <4){ return ((BASE_PREMIUM*value) * agePremium) * ticketPremium; } else { System.out.println("Sorry, you have too many tickets !!"); return 0; } } */

it does not read the values from my methods and instead reads the 1 from the declaration and initialization.

private double agePremium =1; private double ticketPremium =1;

and it multiplies them.

How do i get them to link them to each other and replace the 1 with the new values and multiply. Thanks

import java.util.Scanner; public class Driver { private int age; private int ticket; private double value; final double BASE_PREMIUM=0.05; private double agePremium =1; private double ticketPremium =1; Scanner scanner = new Scanner(System.in); public void read() { System.out.println("Driver’s Age?"); age = scanner.nextInt(); System.out.println("Number of Tickets?"); ticket = scanner.nextInt(); System.out.println("Value of Car?"); value = scanner.nextDouble(); } public double premium() { if (ticket <4){ return ((BASE_PREMIUM*value)*agePremium)*ticketPremium; } else { System.out.println("Sorry, you have too many tickets !!"); return 0; } } public void premiumAge() { if (age > 29) { agePremium += 0; } else if (age <= 29 && age >= 25) { agePremium += 0.10; } else { agePremium += 0.15; } } public void premiumTicket() { switch (ticket) { case '1': ticketPremium += 0.1; break; case '2': ticketPremium += 0.25; break; case '3': ticketPremium += 0.50; break; case '0': ticketPremium += 0.00; default: ticketPremium = 0.00; break; } } }

You need to add <tr> in while loop like,

<?php $result = mysql_query("SELECT * FROM A"); while($row=mysql_fetch_array($result)){ ?> <tr> <!-- add this tr --> <td><?php echo $row["source_id"]; ?></td> <td><?php echo $row["escl_status"]; ?></td> <td><?php echo $row["escl_notice"]; ?></td> </tr> <?php } ?>

Also change .odd to :odd in your jquery selector,

$("#report tr:odd").click(function(){ // :odd not .odd $(this).next("tr").toggle(); $(this).find(".arrow").toggleClass("up"); });

Which actually becomes <textarea name=mp3link and then you escape the double quotes: id=\"mp33\" which becomes id="mp33". Its easier to just write ('<textarea att="value"').

Second, why dont you just create the audio and set the src via method?

snd1 = new Audio(); snd1.src = $(mp33).val(); snd1.play();

Does $(mp33) even exist?

Edit: I just saw you are using the textarea to get the value, but rather use the .text() method:

snd1 = new Audio(); snd1.src = $('#mp33').text(); snd1.play();

Putting aside the argument of whether dates should be stored in UTC or not, the place to check for these kinds of things in your code is in the build process, or failing that, using a pre-commit hook.

The latter will only allow the developer to commit code that adheres to your standards. Doing it at the database layer is too late, IMO.

1166114 0 Checkbox user selection validation question

I have a checkbox, the business rule is it has to be selected by user manually (so that he is aware what he is doing, not check automatically by the program).

If the user didn't check it, we need to show an error msg. How should apply the validation by ASP.NET? RequiredFieldValidator or something?

Thanks,

31120987 0 Go: "tail -f"-like generator

I had this convenient function in Python:

def follow(path): with open(self.path) as lines: lines.seek(0, 2) # seek to EOF while True: line = lines.readline() if not line: time.sleep(0.1) continue yield line

It does something similar to UNIX tail -f: you get last lines of a file as they come. It's convenient because you can get the generator without blocking and pass it to another function.

Then I had to do the same thing in Go. I'm new to this language, so I'm not sure whether what I did is idiomatic/correct enough for Go.

Here is the code:

func Follow(fileName string) chan string { out_chan := make(chan string) file, err := os.Open(fileName) if err != nil { log.Fatal(err) } file.Seek(0, os.SEEK_END) bf := bufio.NewReader(file) go func() { for { line, _, _ := bf.ReadLine() if len(line) == 0 { time.Sleep(10 * time.Millisecond) } else { out_chan <- string(line) } } defer file.Close() close(out_chan) }() return out_chan }

Is there any cleaner way to do this in Go? I have a feeling that using an asynchronous call for such a thing is an overkill, and it really bothers me.

You are very welcome if any questions

^{Updated after rereading the question.}
You are mixing GROUP BY and DISTINCT ON. What you want (how I understand it) can be done with a window function combined with a DISTINCT ON:

SELECT DISTINCT ON (a) a, b, c , count(d) OVER (PARTITION BY a, b, c) AS d_ct , e FROM tbl ORDER BY a, d_ct DESC;

Window functions require PostgreSQL 8.4 ore later.

What happens here?

Count in d_ct how many identical sets of (a,b,c) there are in the table with non-null values for d.
Pick exactly one row per a. If you don't ORDER BY more than just a, a random row will be picked.
In my example I ORDER BY d_ct DESC in addition, so a pseudo-random row out of the set with the highest d_ct will be picked.

Another, slightly different interpretation of what you might need, with GROUP BY:

SELECT DISTINCT ON (a) a, b, c , count(d) AS d_ct , min(e) AS min_e -- aggregate e in some way FROM t GROUP BY a, b, c ORDER BY a, d_ct DESC;

GROUP BY is applied before DISTINCT ON, so the result is very similar to the one above, only the value for e / min_e is different.

I've created a possibility by using the informations from Glix @Glix I use the EEPlus Lib to create multiple Worksheets.

For exmaple in a way like this:

private MemoryStream createMemoryStream(DataTable[] tables, int[] divs) { MemoryStream ms = new MemoryStream(); ExcelPackage pck = new ExcelPackage(); for (int i = 0; i < tables.Length; i++) { ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Division_" + divs[i].ToString()); ws.Cells["A1"].LoadFromDataTable(tables[i], true); } pck.SaveAs(ms); return ms; }

The MemoryStream could be used for a Response.BinaryWrite. In this way you could download the Excel File with different Tabs/Worksheets.

38713111 0 In mysql database which table store as MyISAM type and which table store as InnoDB type ? And Why?

I am using Both types in my database. And Found information regarding these two types as i given following : 1. InnoDB locks the particular row in the table, and MyISAM locks the entire MySQL table. 2. MyISAM is the original storage engine. It is a fast storage engine. It does not support transactions. 3. InnoDB is the most widely used storage engine with transaction support. It is an ACID compliant storage engine.

So, I am confused on which table store as MyISAM type and which table store as InnoDB type in My database. Please provide suggestion to me.

The NetworkInformation.GetInternetConnectionProfile() on Windows Phone 8 is a newer WinRT based API but unfortunately it doesn't look like most of the methods were implemented.

At runtime, using the debugger, you'll see that nearly all of the properties throw exceptions of type NotImplementedException. But because the methods and properties were stubbed, Visual Studio doesn't know any better and allows the code to be compiled.

I have tested the following methods in WP8 SL, WP8.1 SL, WP8.1 XAML projects with the WP8 and WP8.1 emulators, where possible, to confirm the following...

Windows Phone 7.5 and 8.0

As NetworkInformation.GetInternetConnectionProfile() either isn't implemented fully (or at all on 7.5), the MSDN documentation recommends...

DeviceNetworkInformation.IsNetworkAvailable();

Note: this can still be used in Windows Phone 8.1 Silverlight

Windows Phone 8.1 SL and XAML/WinRT

Due to increasing convergence between Windows 8 and Windows Phone 8, nearly all of WinRT APIs are now available in Windows Phone 8.1. If you're making a Windows Phone 8.1 (SL or XAML) or a Universal all (Windows 8.1 + Windows Phone 8.1), it makes sense to use the latest API...

6511542 0 Force JavaScript exception/error when reading an undefined object property?

I'm an experienced C++/Java programmer working in Javascript for the first time. I'm using Chrome as the browser.

I've created several Javascript classes with fields and methods. When I read an object's field that doesn't exist (due to a typo on my part), the Javascript runtime doesn't throw an error or exception. Apparently such read fields are 'undefined'. For example:

var foo = new Foo(); foo.bar = 1; var baz = foo.Bar; // baz is now undefined

I know that I can check for equality against 'undefined' as mentioned in "Detecting an undefined object property in JavaScript", but that seems tedious since I read from object fields often in my code.

Is there any way to force an error or exception to be thrown when I read an undefined property?

And why is an exception thrown when I read an undefined variable (as opposed to undefined object property)?

21760294 1 How do I report results back to the main process from multiple processes?

I currently have 18 functions that perform different sets of validations on large XML files. I've created a custom ValidationWarning class that extends UserWarning, and these functions raise warnings for each validation failure. In the end, I need to produce an XLSX report containing all of the failures (identifying information for each failure is available in the ValidationWarning object).

I'm planning to spawn a process for each function (I saw examples where tasks were placed in a JoinableQueue, but I don't understand why this is necessary, unless the task list will be modified later). The order of the validation failures is irrelevant, and I don't need to see the results until all of the validations have finished. Should I replace the showwarning() function for each validation function to write to a list returned by Manager()? I can export the results to XLSX after joining all of the processes. Is this better than writing to a Queue? Queue may be faster, but writing results isn't a bottleneck, and I don't understand how I'd solve the following problem (see http://docs.python.org/2/library/multiprocessing.html#programming-guidelines):

This means that whenever you use a queue you need to make sure that all items which have been put on the queue will eventually be removed before the process is joined. Otherwise you cannot be sure that processes which have put items on the queue will terminate.

Is there a better approach that I'm ignoring? To my understanding, I can't use a catch_warnings context manager in the main process and expect it to catch warnings from each validation process, although I haven't tested it yet (edit: I tested it, and, as expected, it fails). Writing to XLSX directly instead of getting all of the results first also sounds difficult, because I'd need to create a blank XLSX file and update it in each process while managing access to the shared XLSX file.

Thank you!

Instead of appending the data, generate the output with one execution of the template:

package main import ( "fmt" "os" "text/template" ) var t = template.Must(template.New("").Parse(` type Client struct { Opts *ClientOpts Schemas *Schemas Types map[string]Schema {{range .}} Container *{{.schema.Id}}Client{{end}} } `)) type schema struct { Id string } func main() { data := []map[string]interface{}{ {"schema": schema{Id: "abcClient"}}, {"schema": schema{Id: "xyzClient"}}, } if err := t.Execute(os.Stdout, data); err != nil { fmt.Println(err) } }

Try it on the playground.

As suggested in Matthieu M.'s comment, it is the linker job to find the right "function" at the right place. Compilation steps are, roughly:

The compiler is invoked for each cpp file and translate it to an object file (binary code) with a symbol table which associates function name (names are mangled in c++) to their location in the object file.
The linker is invoked only one time: whith every object file in parameter. It will resolve function call location from one object file to another thanks to symbol tables. One main() function MUST exist somewhere. Eventually a binary executable file is produced when the linker found everything it needs.

518082 0 php htmlspecialchars() from one form to another

Why can't htmlspecialchars() continually encode characters after each form submission? Take a look at the following example:

<?php $_POST['txt'] = htmlspecialchars($_POST['txt']); ?> <form method="post"> <input name="txt" value="<?=$_POST['txt'] ?>" /> <input type="submit" name="save" value="test" /> </form>

You can see it at running at http://verticalcms.com/htmlspecialchars.php.

Now do the following

1) Type & into the text field 2) Hit the test button once 3) When the page completes post back, hit the test button again 4) When the page completes post back, view the page source code

In the input box, the value is & amp;

I was expecting & amp; amp;

Why is it not & amp; amp; ???

40310595 1 How to not block making initial connection with python requests?

I have a server that uses requests to make queries to another server that may or may not be running. If that server is not running, I do not want to block for a long time; I can just handle the error right away. However, the timeout parameter does not seem to apply to the process of making the initial connection.

From the terminal, I run:

>>> import time >>> import requests >>> t1 = time.time() ; exec("try: requests.get('http://192.168.99.100/', timeout=1.0)\nexcept: pass") ; t2 = time.time() ; t2 - t1 21.00611114501953

This takes about 21 seconds and has no dependance on the timeout I give. I also tried using eventlet's timeout, but it turned out the same:

>>> import time >>> import eventlet >>> requests = eventlet.import_patched('requests') >>> t1 = time.time() ; exec("try: \n with eventlet.Timeout(1): requests.get('http://192.168.99.100/')\nexcept: pass") ; t2 = time.time() ; t2 - t1 21.00276017189026

The error I am getting for the connection is:

ConnectionError: ('Connection aborted.', error(11, 'Resource temporarily unavailable'))

Finally, I am running python under the Windows Subsystem for Linux, which might be working with sockets differently.

Seems to partially work. Writing files seems to be fine but it seems to be failing on any runcmd. I think if you can get away w/ it do this:

In the VM metadata create a key called user-data with your entire cloud config script in it as text. That will be picked up by the VM as it comes up.

Then in startup-script paste all your commands you'd put in runcmd.

All this may have ordering issues for you of course, but I don't any other way to do it.

It's actually not so hard to get this to work. It's a bit hacky since you are adding code to the engine's routes.rb file that changes depending on which env it's running in. If you are using the spec/dummy site approach for testing the engine then use the following code snippet in /config/routes.rb file:

# <your_engine>/config/routes.rb if Rails.env.test? && Rails.application.class.name.to_s == 'Dummy::Application' application = Rails.application else application = YourEngine::Engine end application.routes.draw do ... end

What this is basically doing is switching out your engine for the dummy app and writing the routes to it when in test mode.

36041131 0 Mysql query for list of followers

I am trying to figure out how I can obtain the list of user followers and his/her status of following to them. For example, I have 10 followers, and I need to know if I am following them or not. It's a feature like on Instagram, when you can observe people and be observed.

I have one table:

follower user_id reg_dt followed 1 2 date true

In above mentioned example user 1 is followed by user 2. If the user will unfollow, the flag will be false, but it will be in DB.

I want to achieve:

follower user_id reg_dt followed logged_user_follower 1 2 date true false

It means that user 1 is followed by user 2, but user 1 is not following user 2.

I tried 2 queries:

select follower.follower_id as follower, follower.user_id as user_id, follower.followed as followed, follower.reg_dt as reg_dt from tb_follower follower where follower.follower_id=1 and follower.followed=1;

to get list of followers (of user 1) and:

select 1 as logged_user_follower from tb_follower follower where follower.follower_id=follower.follower_id and follower.followed=1 and follower.user_id = follower.user_id limit 1

to get the status logged_user_follower.

I don't know how to merge this to queries, to do one efficient, to get list all the followers of particular user and his/her status of following to them.

Any help will be appreciated. Thanks.

I believe you want your MainHash with same key in MainArray.

So, you can try,

 for (String item : array_items) { entity.addPart("MainHash[MyArray][]", new StringBody(item)); }

It will create,

[one,two,three]

as an array.

Now, what i've done is create a new object of the Consumer class called cons, and then i use that to call on the class methods for testing. For example, Consumer has a simple method that checks if a file exists in a given directory. The test i've made looks like this

import Consumer from Consumer import Consumer cons = Consumer('mockconfig.config', 'logque1') class TestConsumerMethods(unittest.TestCase): def test_fileExists(self): self.assertEqual(cons.file_exists('./dir/', 'thisDoesntExist.config), False) self. assertEqual(cons.file_exists('./dir/', thisDoesExist.config), True)

Is this the correct way to test my class? I mean, ideally i'd like to just use the class methods without having to instantiate the class because to "isolate" the code, right?

This code should loop through all POST and insert them into a hidden input field. Put it inside the <form> tags, and it should be submitted with the subsequent post.

Remember to properly escape the output.

foreach($_POST as $name => $value){ echo '<input type="hidden" name="'.$name.'" value="'.$value.'" />'; }

Or you can save away the data in the manner you choose.

28280287 0 Image data not sending properly - Ajax, Cordova

The following code is to take picture and send to server using ajax, but the image data not properly send.

 <script> var pictureSource; // picture source var destinationType; // sets the format of returned value var image = ""; document.addEventListener("deviceready", onDeviceReady, false); function onDeviceReady() { function alertDismissed() { }; pictureSource = navigator.camera.PictureSourceType; destinationType = navigator.camera.DestinationType; } function capturePhoto() { navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50, destinationType: destinationType.DATA_URL }); } function onPhotoDataSuccess(imageData) { var smallImage = document.getElementById('smallImage'); smallImage.style.display = 'block'; smallImage.src = "data:image/jpeg;base64," + imageData; image = "data:image/jpeg;base64," + imageData; alert("Image = "+image); } function onFail(message) { alert('Failed because: ' + message); } function submitFunction() { function alertDismissed() { }; var dataString = 'image='+image; $.ajax({ type: "POST", url: "url.php", data: dataString, cache: false, success: function(result){ } }); } </script> <input type="button" id="camera" class="btn btn-primary btn-large btn-block" value="Take Photo" onclick="capturePhoto();"/> <input type="submit" class="btn btn-primary btn-large btn-block" value="Next" onclick="submitFunction();" /> <img style="display:none;width:60px;height:60px;" id="smallImage" src="" />

The image is displaying properly, and alert shows "Image = data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDABALDA4M......o7cUAPFJR9KWmgP/9k=".

But, in the following php, the $_POST['image'] is not receiving the proper data, it missing somecharacters like '+' and also replacing it with space or new line. So, when I returning back from db in other page, image not displayed properly.

url.php

$con=mysql_connect('server','user','password') or die("Failed to connect to MySQL: " . mysql_error()); $db=mysql_select_db('db',$con) or die("Failed to connect to MySQL: " . mysql_error()); $retval = mysql_query( "UPDATE tablename SET photo='".$_POST['image']."' WHERE ID='".$_POST['id']."'", $con ); echo $_POST['image'];

3309473 0 Spring-Hibernate used in a webapp,what are strategies for Thread safe session management

I'm developing a web app with Spring and Hibernate and I was so obsessed by making he application thread safe and being able to support heavy load that based on my boss recommendation I end up writing my own session and a session container to implement a session per request pattern. Plus I have a lot of DAOs and me not willing to write the same save method for all the DAOs I copy paste this Hibernate GenericDAO (I can't tell it's the same thing because at the time hibernate wasn't owned by jboss) and do the plumbing stuff, and under pressure, all become quickly complicated and on production, the is StaleObjectException and duplicated data right, and i have the feeling that it's time to review what I've done, simplify it and make it more robust for large data handling. One thing you should know is that one request involves many DAO's.

There is quartz running for some updates in the database.

As much as I want to tune everything for the better I lack time to do the necessary research plus Hibernate is kind of huge (learning).

So this is it, I'll like to borrow your experience and ask for few question to know what direction to take.

Question 1 : is Hibernate generated uuid safe enough for threading environment and avoiding StaleObjectException?

Question 2 what are best strategy to use hibernate getCurrentSession in threadSafe scenario (I've read about threadlocal stuff but didn't get too much understanding so didn't do it)

Question 3 : will HIbernateTemplate do for the simplest solution approach?

Question 4 : what will be your choice if you were to implement a connection pool and tuning requirement for production server?

Please do no hesitate to point me to blogs or resources online , all that I need is a approach that works for my scenario. your approach if you were to do this.

Thanks for reading this, everybody's idea is welcomed...

26950401 0 Swift search string for any number?

I'm trying to get my app to identify dates. I have an array of strings that it searches through. I'm using rangeOfString() to search for a "/", which is in the dates. However, some areas in the strings have backslashes that aren't part of dates, and that messes up the search. Can I get it to search for a backslash immediately followed by a number. In PHP, it would be preg_match("///[0-9]/"), but how is it done with Swift?

Another way to customize is as following:

columns: [ { command: [{ name: 'edit', click: editButtonClick, template: editButtonTemplate }], title: 'Edit', width: '40px'}..] var editButtonTemplate = '<a class="btn btn-link btn-xs k-grid-edit" href="\\#"><span class="glyphicon glyphicon-pencil"></span></a>'; editButtonClick = function (e) { /* Changes default rendering of 'update' & 'cancel' buttons * but keeps default behaviour */ var btnCancel = $('.k-grid-cancel'); btnCancel.removeClass('k-button k-button-icontext').addClass('btn btn-link btn-xs'); btnCancel.text(''); btnCancel.append('<span class="glyphicon glyphicon-ban-circle"></span>'); var btnOk = $('.k-grid-update'); btnOk.removeClass('k-button k-button-icontext k-primary').addClass('btn btn-link btn-xs'); btnOk.text(''); btnOk.append('<span class="glyphicon glyphicon-ok-circle k-update"></span>');

}

This approach handles click event of standard edit command and modifies rendered html, but preserves standard functionality.

Important detail - grid's update functionality is coupled to element with k-update attribute, while cancel functionality rides on k-grid-cancel.

37851143 0 24/August/2016 12:44 AM Not valid in Safari on Mac

I have done quite a bit to make sure the date my date picker creates is compatible for being converted into a javascript Date object. I followed the advice on this stack overflow entry: Invalid date in safari and removed dashes from the string using: new Date('24-August-2016 12:44 AM'.replace(/-/g, "/")); That made things compatible with every other operating system and browser, except browsers on a Mac. It still seems safari does not like the full month name in the string. What is the recommended approach to getting safari to recognize the string as a date if I am forced to use that format?

There's a lot of discussion on whether REST URIs should have verbs or not, but that's merely a fetish. When it comes to URIs, what determines if your API is more or less RESTful isn't their design, but how your client obtains them. If you can't change your URIs anytime you want, it's not RESTful. If your clients are reading URI patterns from documentation and replacing fields like :id with values to build the final URIs to be used, that's not RESTful, it doesn't matter what the content of the URI is. Do some research on HATEOAS for more information on that.

With that part out of the way, POST is the method used for any action that isn't standardized by HTTP, which means you can usually do almost anything you want and still say it's RESTful, as long as it's clearly documented and the URI isn't from out-of-band information. You can guess what a GET, PUT, PATCH or DELETE does based on the HTTP standard, but you can't guess what a POST does.

Just be careful that you don't make your POSTs like an RPC method. For instance, don't do something where the resource the POST is applied to is identified by the payload instead of the URI. In your case, something like:

POST /explore {"region_id": :id}

This is what's really meant by the mantra to avoid verbs or method names in the URI.

Here I think a user-defined conversion operator would be more appropriate.

class rational { public: rational( int iNum, int iDen ) : num( iNum ), den( iDen ) {} // ... operator double() { return (double)num / (double)den; } private: int num; int den; }; int main() { rational r( 1, 2 ); double n = r; std::cout << r << std::endl; // output 0.5 return 0; }

Here is a little live example to illustrate this : http://ideone.com/I0Oj66

About the copy assignment operator= :

A copy assignment operator of class T is a non-template non-static member function with the name operator= that takes exactly one parameter of type T.

The operator= is used to change an existing object.

You can use it for example to copy the state of another object :

rational &operator=( const rational &rhs ) { num = rhs.num; den = rhs.den; return *this; }

CATransaction works on Core Animation layer animations. CATransaction is cross-platform between iOS and Mac OS.

NSAnimationContext works with an NSAnimationContext. It's Mac OS specific.

(The NS animation stuff is Mac-only, and the UIView animation stuff is iOS only.)

I work in iOS more than Mac OS these days, and I always look for cross-platform ways to do things.

CAAnimation, CALayer, CAAnimationGroup, etc, are nearly identical between Mac and iOS. There are some differences (e.g. quicktime layers are not supported in iOS, Core Image support is more limited in iOS, etc.) but CA stuff is more alike than different.

On this line:

You mispelled your variable $anchor. Change it to:

Either way I recommend you to learn how to use the dev-tools of your browser and especially how to use break points so you can check yourself what variable doesn't behave as you would expect.

There are a few java applet ssh clients you could set up an a machine. I've used mindterm, but it's abandoned.

If the Internet cafe has Windows machines where you can install software, then you're all set. (not uncommon; I was usually able to install putty so I could check my email in Austria, Germany, and Italy on a 3-week trip in 2005.) WinSCP lets you run a text editor on remote files, which would otherwise be painful over a high-latency connection. Most version control systems have command line interfaces, so that should cover most of it.

I'm an old-school command line junkie, so I'm fine with ssh... Your needs may vary.

Just make sure your remote machine has a good UPS and will boot up ok after a power cycle. You'll be too far away to nudge it along if you haven't tested rebooting since last time you changed any config files.

I'm researching this subject intensively since Aug-2014. Firstly, I hope that you're familiar with some telecom knowledge and Android Open Source Project (AOSP). Well, based on my researches, I state that:

By looking at AOSP internal native classes, it seems that Android gives SignalStrength values by parceling returned values from AT+CSQ command (please, check AOSP native class reference-ril.c) over the modem. And only from it. The problem is that this command only gives the signal quality coupled with block error rate (BLER), and do not inform anything about other incoming signals; In LTE modem it seems to be OK in some devices, but when you change to UMTS network, things become unclear/inconsistent;
You may calculate incoming interference (SNR and others) by using some derivations from telecom formulas (relating RSSI, RSCP, EcNo, and so on...) by yourself with received signal strengths from other cells, or with the AT+CGREG and AT+CREG (again, please check reference-ril.c class).;
I digged all AOSP internal classes, tracing and diagraming method calls related with telephony. I've looked all from the SDK layer (where we use TelephonyManager and PhoneStateListener API classes), over to the native radio interface layers classes written in c/c++. In any moment I have found a SNQ calculation truly based in other cells, but only passed as a value obtained from the modem with AT+CSQ (this command gives only signal quality and BLER). It sounds strange for me, because interference is a value calculated with other received signals, inclusively those ones that are not from GSM. So, for me, the incoming SNR got from Android API is somewhat lame or incomplete.

Based on the above, I suppose that:

Google is not 3GPP. And 3GPP is not Google. Android is a huge and complex project with more than 12 million lines of code. It is very plausible that communication/theoretical informations may be missed among Android and telecom;
In particular I'm searching for CQI, and I suspect that CQI is in the context of LQR (Link Quality Report), calculated in the L2 PPP (Point-to-Point Protocol);
The subject of this thread is really problematic. There will be no holy grail, because different devices owns different (maybe closed) hardware drivers. We'll need to support different softwares for each different device. Maybe, you'll need to recompile an entire Android ROM for each device, if you need to have a correct value for all device.

I hope that it brings some light to you. If you have any additional information, please share it here.

33055940 0 Swift with objective-git: Overloads for 'createCommitWithTree' exist with these partially matching parameter lists

I am using objective-git with Swift and cannot compile the GTRepository.createCommitWithTree method.

The method can optionally be called without author : GTSignature and committer : GTSignature parameters.

I'm new to Swift and overloading functions. I'd like to know how to structure this so it will compile.

My code uses all the types specified in the objective-git method:

func commitTree ( tree : GTTree ) { let message : NSString let author : GTSignature let committer : GTSignature let parents : NSArray let updatingReferenceNamed : NSString var error : NSError? GTRepository.createCommitWithTree( tree, message, author, committer, parents, updatingReferenceNamed, &error ) }

In this code, compiler cannot invoke method with an argument list of these types. Compiler provides additional information: "Overloads for 'createCommitWithTree' exist with these partially matching parameter lists: (GTTree, message: String, author: GTSignature, committer: GTSignature, parents: [AnyObject]?, updatingReferenceNamed: String?), (GTTree, message: String, parents: [AnyObject]?, updatingReferenceNamed: String?)"

If I refactor to use the types suggested above, compiler won't compile with "Ambiguous reference to member 'createCommitWithTree'"

How do I write this to compile?

Thanks

There is an overhead associated with lazyness — the compiler has to create a thunk for the value to store the computation until the result is needed. If you know that you'll always need the result sooner or later, then it can make sense to force the evaluation of the result.

shmat() is a typical example of same physical address being mapped as two different virtual address in two different processes. If you do pmap -x pid_A . you will you see the virtual mem map for process A similarly for Process B. Actual Phy mem is not exposed to the user-space program.

Now SayProcess A and B share a shared memory segment and shared memory pointer be sh_mem_ptr_A and Sh_mem_ptr_B. If you print these pointers their address(virtual) will be different. Because Sh_mem_ptr_A is a part of memory map of Process A, Similarly sh_mem_ptr_B for Process B.

Kernel maintains the maaping of Virtual-to- phy addr. By page table and offset. Higher bits map to the page table and offset maps to offset in the page table. So If you notice the Lower order bits of sh_mem_ptr_A and sh_mem_ptr_B they will be same(but may not be true always).

Sometimes it helps to rephrase the problem: if I read you well, you don't want users, that have a deny time with at least one specified DayID/Hour/Minute:

where !i.UserDeniedTimes.Any( p => (p.AllowedDate.AllowedTimes.Any( a1 => a1.DayID == aTime.DayID && a1.Hour == aTime.Hour && a1.Minute == aTime.Minute )) )

This should select the users you want. If not, please tell in some more words what exactly you are trying to achieve.

I would create a helper class that takes an input operation, starting it, and cancelling the existing one, and overwriting its internal variable. As you cant perform a Cancel() explicitly and directly on a Task<T>, you will need to keep your own TaskCancellationSource handy. If you want to provide an external token, you can combine them with CancellationTokenSource.CreateLinkedTokenSource(...) If you need to keep an eye on the result, that would make a good opportunity for TaskCompletionSource.

public class OverwriteTaskHandler<T> { private Task<T> _task; private TaskCompletionSource<T> _tcs; private CancellationTokenSource _cts; public OverwriteTaskHandler(Func<T> operation) { _tcs = new TaskCompletionSource<T>(); _cts = new CancellationTokenSource(); TryPushTask(operation); } public bool TryPushTask(Func<T> operation) { if (_tcs.Task.IsCompleted) return false; //It would be unsafe to use this instance as it is already "finished" _cts.Cancel(); _cts = new CancellationTokenSource(); _task = Task.Run(operation, _cts.Token); _task.ContinueWith(task => _tcs.SetResult(task.Result)); return true; } public void Cancel() { _cts.Cancel(); } public Task<T> WrappedTask { get { return _tcs.Task; } } }

If you really want to split into separate subs then you should use parameters in place of globals:

E.g.

Function mkArray() Dim areaArr As Variant, i As Long areaArr = ActiveSheet.Range("I1:J16").Value For i = 1 To UBound(areaArr, 1) ColorShape Cstr(areaArr(i, 1)), areaArr(i, 2) Next i End Function Sub ColorShape(shpName as string, shpVal) Const COLR_GREEN As Long = 11 Const COLR_RED As Long = 2 Sheets("Sheet1").Shapes(shpName).Fill.ForeColor.SchemeColor = _ IIf(shpVal > 500, COLR_GREEN, COLR_RED) End Sub

Its is just because of Class.forName() is dynamically loaded at run time your class into memory(RAM). and it will execute all static block within this class without creating reference of that class,

From offical doc:

A call to Class.forName("X") causes the class named X to be dynamically loaded (at runtime). A call to forName("X") causes the class named X to be initialized (i.e., JVM executes all its static block after class loading). Class.forName("X") returns the Class object associated with the "X" class. The returned Class object is not an instance of the "x" class itself.

Class.forName("X") loads the class if it not already loaded. The JVM keeps track of all the classes that have been previously loaded. This method uses the classloader of the class that invokes it. The "X" is the fully qualified name of the desired class.

35573235 1 Why some part of code is not participate in execution process

I am trying to split network into two groups (g1 and g2) according to the degree of nodes (if degree of node d>=691 then node is add in g1 otherwise node is add in g2)

import networkx as nx import random import numpy as np import os import sys from networkx.algorithms.assortativity.mixing import degree_mixing_matrix # \attribute_mixing_matrix, numeric_mixing_matrix from networkx.algorithms.assortativity.pairs import node_degree_xy #, \node_attribute_xy from operator import itemgetter from networkx.exception import NetworkXError import networkx.convert as convert g = nx.read_edgelist('/home/suman/Desktop/dataset/Email-Enron.txt',create_using=None,nodetype=int,edgetype=int) s=sorted(g.degree_iter(),key= itemgetter(1),reverse=True) perc=1 def modify_nw_random(g,perc): while(perc<=100): ntm = round((float(perc)/100)*len(g)) #print ntm while(ntm != 0): v = random.randrange(1,len(g)) print"node:", v d=g.degree(v) print"degree:", d g1=nx.Graph() g2=nx.Graph() if g.has_node(v) and (d>=691): g1.add_node(v) else: g2.add_node(v) g.remove_node(v) ntm = ntm-1 if(ntm<=0):break perc=perc+1 print "perc:",perc if(perc>100):break N1=nx.number_of_nodes(g1) print N1 r2=nx.degree_assortativity_coefficient(g1) print ("%f"%r2) N2=nx.number_of_nodes(g2) print N2 r3=nx.degree_assortativity_coefficient(g2) print ("%f"%r3) modify_nw_random(g,perc)

here first loop are executed when perc = 1 and then perc is increase by 1 (perc=perc+1) this is not execute .it means following part of code is not participating in execution process

perc=perc+1 print "perc:",perc if(perc>100):break print "node in g1:", g1.nodes() print "node in g2:", g2.nodes() N1=nx.number_of_nodes(g1) print N1 r2=nx.degree_assortativity_coefficient(g1) print ("%f"%r2) N2=nx.number_of_nodes(g2) print N2 r3=nx.degree_assortativity_coefficient(g2) print ("%f"%r3)

can any one help me that, for solving my mistakes in this code

31242924 0 jQuery hide the divs based on the classes getting from server

<div class="mianBlock"> <div class="firstBlock"> div content goes here </div> <div class="secondBlock"> div content goes here </div> <div class="thirdBlock"> div content goes here </div> </div>

Using jQuery, how do I hide the 2 blocks?

13725983 0 use the css3 transform-origin to center and zoom

I have a series of divs on my page. Each div has a background image and is arranged in a grid formation. There are an abitrary number of divs on my page. The page is constrained to a size using <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">

I want to be able to click on a div, have it scale to a specific scale, and center.

My markup:

<body id="body"> <div id="container" style="position: relative"> <div id="pack1" class="screenItem cardPack"></div> <div id="pack2" class="screenItem cardPack"></div> <div id="pack3" class="screenItem cardPack"></div> <div id="pack4" class="screenItem cardPack"></div> </div> </body>

my css:

I have a fudge which almost works:

$(cardPack).click(function() { var left = $(cardPack).position().left; var top = $(cardPack).position().top; $(cardPack).css("-webkit-transform", "scale(2.5,2.5)"); $(cardPack).css("-webkit-transform-origin", (3*(left/4)) + " " + (3*(top/4))); });

But I think that's more of a coincidence and luck. My brain is not working to the point where I can workout where to set the transform-origin so that the image will end up in the center of the screen, regardless of its start point.

I am happy to consider alternatives to transform-origin to make this happen.

Try mapping the Option[java.util.Date] to an Option[java.sql.Date] like this:

(success._6).map(d => new java.sql.Date(d.getTime))

One more word of advice, you might want to actually map this to a java.sql.Timestamp so you don't lose any time precision when writing it to the DB as I believe will be the case with java.sql.Date. So the code would be:

(success._6).map(d => new java.sql.Timestamp(d.getTime))

What you're talking about is called a callback and is implemented with function pointers in C and C++.

Since you mentioned glut, let's take a real example directly from the freeglut source code. I'll use glutIdleFunc instead of glutTimerFunc because the code is simpler.

In glut, the idle function callback (what you supply to glutIdleFunc) is a pointer to a function that takes no parameters and returns nothing. A typedef is used to give such a function type a name:

typedef void (* FGCBIdle)( void );

Here, FGCBIdle (short for FreeGlut CallBack Idle) is defined as a pointer to a function that takes no parameters and whose return type is void. This is just a type definition that makes writing expression easier, it doesn't allocate any storage.

Freeglut has a structure called SFG_State that holds various settings. Part of the definition of that structure is:

struct tagSFG_State { /* stuff */ FGCBIdle IdleCallback; /* The global idle callback */ /* stuff */ };

The struct holds a variable of type FGCBIdle, which we established is another name for a specific function pointer. You can set the IdleCallback field to point to the address of a function that is supplied by the user using the glutIdleFunc function. The (simplified) definition of that function is:

void glutIdleFunc( void (* callback)( void ) ) { fgState.IdleCallback = callback; }

Here, fgState is a SFG_State variable. As you can see, the glutIdleFunc takes one parameter which is a function pointer to a function that takes no parameters and returns nothing, this parameter's name is callback. Inside the function, the IdleCallback inside the global fgState variable is set to the user supplied callback. When you call the glutIdleFunc function, you pass the name of your own function (e.g. glutIdleFunc(myIdle)), but what you're really passing is the address of the function.

Later, inside the big glut event processing loop initiated by glutMainLoop, you'll find this code:

if( fgState.IdleCallback ) { /* stuff */ fgState.IdleCallback( ); }

If a user supplied idle callback is available, it is called in the loop. If you check the function pointer tutorial at the beginning of my post you will understand the syntax better, but I hope the general concept makes more sense now.

I wouldn't go for a switch at all.

There is no reason to use chaining at all here. Just do

// if (!/^(original|large|medium|small)$/.test(style.name)) throw new Error(…); var x = gm(response.Body) .setFormat('jpg') .autoOrient() .resize(style.w, style.h, style.option); if (style.name == "medium" || style.name == "small") x = x.crop(style.w, style.h, style.crop.x_offset, style.crop.y_offset) .repage('+'); if (style.name == "large" || style.name == "small") x = x.quality(style.quality); if (style.name == "large" || style.name == "medium" || style.name == "small") // possibly better than if (style.name != "original") x = x.strip() .interlace('Plane'); x.toBuffer(next);

But if you're having a large set of options so that it gets unreadable, better factor out each transformation in a function:

function resizedJpg(x) { return x.setFormat('jpg').autoOrient().resize(style.w, style.h, style.option); } function cropped(x) { return x.crop(style.w, style.h, style.crop.x_offset, style.crop.y_offset).repage('+'); } function withQuality(x) { return x.quality(style.quality); } function stripped(x) { return x.strip().interlace('Plane'); }

And then apply them separately:

({ original: [resizedJpg], large: [resizedJpg, withQuality, stripped], medium: [resizedJpg, cropped, stripped], small: [resizedJpg, cropped, withQuality, stripped] }[style.name]).reduce(function(x, trans) { return trans(x); }, gm(response.Body)).toBuffer(next);

IIRC, you need to decorate the delegate signature with a calling convention. Unfortunately, this can only be done via IL or generating the stub with Reflection.Emit.

You can try this:

protected static Type MakeDelegateType(Type returntype, List<Type> paramtypes) { ModuleBuilder dynamicMod = ... ; // supply this TypeBuilder tb = dynamicMod.DefineType("delegate-maker" + Guid.NewGuid(), TypeAttributes.Public | TypeAttributes.Sealed, typeof(MulticastDelegate)); tb.DefineConstructor(MethodAttributes.RTSpecialName | MethodAttributes.SpecialName | MethodAttributes.Public | MethodAttributes.HideBySig, CallingConventions.Standard, new Type[] { typeof(object), typeof(IntPtr) }). SetImplementationFlags(MethodImplAttributes.Runtime); var inv = tb.DefineMethod("Invoke", MethodAttributes.Public | MethodAttributes.Virtual | MethodAttributes.NewSlot | MethodAttributes.HideBySig, CallingConventions.Standard ,returntype,null, new Type[] { // this is the important bit typeof(System.Runtime.CompilerServices.CallConvCdecl) }, paramtypes.ToArray(), null, null); inv.SetImplementationFlags(MethodImplAttributes.Runtime); var t = tb.CreateType(); return t; }

You would have to have the @interface and @implementation have the same class name. Aside from that, it does not matter what file the @interface or @implementation is in as long as the @interface is accessable from the file the @implementation is in (in the same file or #imported.

So in your case, if you did @interface ReceiverViewController... you would be fine.

8049657 0 Stack-buffer based STL allocator?

I was wondering if it practicable to have an C++ standard library compliant allocator that uses a (fixed sized) buffer that lives on the stack.

Somehow, it seems this question has not been ask this way yet on SO, although it may have been implicitly answered elsewhere.

So basically, it seems, as far as my searches go, that it should be possible to create an allocator that uses a fixed size buffer. Now, on first glance, this should mean that it should also be possible to have an allocator that uses a fixed size buffer that "lives" on the stack, but it does appear, that there is no widespread such implementation around.

Let me give an example of what I mean:

{ ... char buf[512]; typedef ...hmm?... local_allocator; // should use buf typedef std::basic_string<char, std::char_traits<char>, local_allocator> lstring; lstring str; // string object of max. 512 char }

How would this be implementable?

The answer to this other question (thanks to R. Martinho Fernandes) links to a stack based allocator from the chromium sources: http://src.chromium.org/viewvc/chrome/trunk/src/base/stack_container.h

However, this class seems extremely peculiar, especially since this StackAllocator does not have a default ctor -- and there I was thinking that every allocator class needs a default ctor.

31776485 0 bootstrap dropdown button is not working inside of the collapsed navbar

I'm building a website that has a dropdown button with two categories. The dropdown works perfectly on a desktop but when the navbar is collapsed on a small screen, it doesnt work. I've looked for an answer here on stack overflow but nothing has my exact same problem. I need the dropdown to show the two links when I touch the dropdown button. This is a bootstrap website that uses a scroll spy to navigate to different sections of a single index.html page. Jquery is embedded properly as well as bootstrap.min.css, bootstrap.js, and bootstrap.css. And also the navbar is fixed to the top of the page. The navbar collapses perfectly on a small screen but its the dropdown that is not working when the navbar is collapsed. To clarify I should say that it is not the navbar toggle button that I am referring to, only the dropdown button inside of the navbar. It will not open to reveal the links when the navbar is collapsed. When i click the caret, the navbar closes.

The problem is that LiveOperationResult.Result isn't necessarily guaranteed to be a Dictionary<string, object>. It is however defined as an IDictionary<string, object>.

Mind you, you don't appear to even need to cast the Result property to a dictionary of any sort; you should be able to use the dynamic variable to directly access the list you want to iterate.

List<object> folders = (List<object>)result.data;

If performance is a concern, it's unclear to me why you'd be bothering to construct an entire array in the first place. Why not just this?

foreach (var item in myItems.Where(FILTER-IT-HERE)) MY-ACTION;

Or:

foreach (var item in myItems) MY-ACTION-WITH-FILTER;

I ask because, while the others are right that you can't really know without testing, I wouldn't expect there to be much difference between the above two options. I would expect there to be a difference, on the other hand, between creating/populating an array (seemingly for no reason) and not creating an array.

29507406 0 I don't understand how this Integration test is failing in Grails

This is a basic mock of a web service where a Patient object is checked for eligibility. I have included the console output to show the test failing.

When I run this test in the groovyConsole it passes.

Basic Patient Class:

class Patient { String firstName, lastName Date dateOfBirth }

Create the patient object:

Patient p1 = new Patient( firstName: 'Mike', lastName: 'Smith', dateOfBirth: new GregorianCalendar(1968, Calendar.AUGUST, 23).time ).save(flush: true, failOnError: true)

Mock setup:

This test normally queries a web service. I need to mock the service due to firewall issues. I build a tree that replicates the service call.

def eligibilityMock(Patient pat) { def tree = { -> return [:].withDefault{ tree() } } def member = tree() if (pat.firstName == "Mike" && pat.lastName == "Smith") { member.memberInfo.memberDetails.value.memberFirstName.value = 'Mike' } member }

I call the mocked service

//def memberInfo = eligibilityMock(p1) def member = humanaEligibilityMock(p1).memberInfo

I expect the firstName to match

assert p1.firstName == memberInfo.memberDetails?.value?.memberFirstName?.value

It seem the values match up, however the assertion fails.

 p1.firstName == memberInfo.memberDetails?.value?.memberFirstName?.value | | | | | | | Mike | | | | [value:[:]] [:] | | | [memberFirstName:[value:[:]]] | | [value:[memberFirstName:[value:[:]]]] | [memberInfo:[memberDetails:[value:[memberFirstName:[value:Mike] false

If it's not a student assignment and you truly are using C++(as your tag says) you should use strings. Now you're using arrays and comparing arrays addresses instead of real strings. In a C++ way your code might look like:

#include <iostream> #include <string> int main() { std::string a ="wasd"; std::string b ="asd"; if(a.substr(1) == b) std::cout << "Yes!\n"; }

Well, there is a better way to find if one string contains another but the code is a direct mapping of your C code to the C++-ish one.

I guess you pass the wrong CGPoint coordinate to the hitTest:withEvent: method causing wrong behavior if the scroll view is scrolled.

The coordinate you pass to this method must be in the target views coordinate system. I guess your coordinate is in the UIScrollView's superview's coordinate system.

You can convert the coordinate prior to using it for the hit test using CGPoint hitPoint = [scrollView convertPoint:yourPoint fromView:scrollView.superview].

In your example you let the container view perform the hit testing, but the container can only see & hit the visible portion of the scroll view and thus your hit fails.

In order to hit subviews of the scroll view which are outside of the visible area you have to perform the hit test on the scroll view directly:

UIView *firstSubview = [_scrollView hitTest:number1RectanglePoint withEvent:nil]; UIView *fifthSubview = [_scrollView hitTest:number5RectanglePoint withEvent:nil];

You can write some custom validation

validate do valid_phone_codes = [ "007", "042", ...] valid_phone_codes.each do |valid_code| # Also handle optional parenthesis return true if self.phone_number.starts_with?(valid_code, "(#{valid_code})") end errors.add(:phone_numbers, "Must start with a valid country code (one of #{valid_phone_codes.join(', ')}") false end

Or if you prefer, you can declare this code in a function def valid_country_codes, and then add a line

validate :valid_country_codes

32486198 0 Sending a sequence of commands and wait for response

I have to update firmware and settings on a device connected to a serial port. Since this is done by a sequence of commands, I send a command and wait until I recive an answer. Inside the answere (many lines) I search for a string that indicates if the operation is finished successfully.

Serial->write(“boot”, 1000); Serial->waitForKeyword(“boot successful”); Serial->sendFile(“image.dat”); …

So I’ve created a new Thread for this blocking read/write method. Inside the thread I make use of the waitForX() functions. If I call watiForKeyword() it will call readLines() until it detects the keyword or timesout

bool waitForKeyword(const QString &keyword) { QString str; // read all lines while(serial->readLines(10000)) { // check each line while((str = serial->getLine()) != "") { // found! if(str.contains(keyword)) return true; } } // timeout return false; }

readLines() reads everything available and separates it into lines , each line is placed inside a QStringList and to get a string I call getLine() which returns the first string in the list and deletes it.

bool SerialPort::readLines(int waitTimeout) { if(!waitForReadyRead(waitTimeout)) { qDebug() << "Timeout reading" << endl; return false; } QByteArray data = readAll(); while (waitForReadyRead(100)) data += readAll(); char* begin = data.data(); char* ptr = strstr(data, "\r\n"); while(ptr != NULL) { ptr+=2; buffer.append(begin, ptr - begin); emit readyReadLine(buffer); lineBuffer.append(QString(buffer)); // store line in Qstringlist buffer.clear(); begin = ptr; ptr = strstr(begin, "\r\n"); } // rest buffer.append(begin, -1); return true; }

The problem is if I send a file via terminal to test the app readLines() will only read a smale part of the file ( 5 Lines or so). Since these lines do not contain the keyword. the function will run once again, but this time it dosnt wait for timeout, readLines just return false immediately. Whats wrong ? Also I'm not shure if this is the right approach... Does anyone know how to send a sequenze of commands and wait for a response each time?

One answer is to hackishly add some get query parameter like has been suggested.

A better answer is to emit a couple of extra options in your HTTP header.

Pragma: no-cache Expires: Fri, 30 Oct 1998 14:19:41 GMT Cache-Control: no-cache, must-revalidate

By providing a date in the past, it won't be cached by the browser. Cache-Control was added in HTTP/1.1 and the must-revalidate tag indicates that proxies should never serve up an old image even under extenuating circumstances, and the Pragma: no-cache isn't really necessary for current modern browsers/caches but may help with some crufty broken old implementations.

What is the value in the cell?

It looks like it is 19240, which means that formatting it to 2DP will return 19240.00, as you are seeing. If you want 192.40, then you'll need to divide by 100 first - you'll not be able to do this with string formats.

8730788 0

I did some of your work for you and found this date:duration function, which you seem to be trying to use. However, date:duration converts a number of seconds into a duration formatted string, whereas you want to find the difference (duration) between two datetime strings.

You probably want date:difference instead. If you read the documentation for this function/template, you'll find this about the arguments:

The two dates must both be right-truncated date/time strings in one of the formats defined in [XML Schema Part 2: Datatypes]. ... The permitted formats are as follows...
xs:dateTime (CCYY-MM-DDThh:mm:ss) ... 

There are italics there in the original: CCYY-MM-DDThh:mm:ss except the T is not italicized. In other words, the time strings need a literal T between the date and the time, whereas yours have a space.

So I would suggest fixing that:

<start>2011-12-13T16:15:26</start> <end>2011-12-13T16:17:27</end>

Pass the start and end strings as parameters to the template. You can do this by just passing the start and end element nodes, which will be automatically converted to strings based on their text content:

<xsl:variable name="time-diff-dur"> <xsl:call-template name="date:difference"> <xsl:with-param name="start" select="start" /> <xsl:with-param name="end" select="end" /> </xsl:call-template> </xsl:variable> <!-- The above returns a duration formatted string, so convert that to seconds: --> <xsl:variable name="time-diff-sec"> <xsl:call-template name="date:seconds"> <xsl:with-param name="seconds" select="$time-diff-dur" />? </xsl:call-template> </xsl:variable>

This code assumes that the context node is the parent of the <start> and <end> elements. After the above code, the variable $time-diff-sec will contain a result tree fragment, which can be converted to a number using number($time-diff-sec) if necessary.

Let us know whether that works. If not, state specifically what the result was and how it differs from what you expected.

Update:

I just noticed that you are using xsltproc (which uses libxslt). According to this documentation, libxslt supports date:difference (and date:seconds) natively. So you can call these functions as functions instead of defining a named template and calling it as a template. That would be a lot less code for you, albeit less portable:

<xsl:variable name="time-diff-sec" select="date:seconds(date:difference(start, end))" />

As before, you will need to declare the date namespace prefix somewhere, usually on your xsl:stylesheet element:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:date="http://exslt.org/dates-and-times" extension-element-prefixes="date">

You want to get an ISO 7185 compliant compiler to compile that. It is true that Pascal-P4 (the proper name) was written prior to the ISO 7185 standard. However, the adaption to the standard is generally less of a change set than adaption to a dielect.

You will find that work already done and documented at:

http://sourceforge.net/projects/pascalp4/

It specifies use of GPC. However, as Marco said, it is possible with more work to adapt to FPC, and I believe the FPC folks are improving the ISO 7185 capability of their compiler.

Having said that, I'm not sure why Pascal-P4 would be an interesting target. Pascal-P4 was a subset compiler, meaning an incomplete implementation of Pascal. You will find a complete implementation as Pascal-P5:

http://sourceforge.net/projects/pascalp5/

And I believe it has less portability issues as well.

Good luck.

You can use .siblings() this way:

$('.image, .icon').hover(function(e) { if(e.type === 'mouseenter' && $(e.target).is('.image')){ $('.icon').stop().animate({"opacity": 0}); $(this).siblings('.icon').stop().animate({"opacity": 1}); } if(e.type === 'mouseleave' && $(e.target).is('.icon')){ $('.icon').stop().animate({"opacity": 0}); } });

and change your context to current selector with $(this)

Is there an error of some sorts, or you just don't understand how that works?

navigator.webkitGetUserMedia expects 3 arguments. One for configuration data, one for a function to call on success (a success callback) and one to call on error.

Note that it expects a function. This code passes a reference to the function by name; it will be called with the appropriate parameter (from within webkitGetUserMedia).

Consider this code, it works in the same manner:

function hello(subject) { alert("Hello, " + subject + "!"); } function passWorldTo(callback) { callback("world"); } passWorldTo(hello);

4556997 0 How to add behavoirs to asp.net mvc 2 action result output

Lets say I have two controllers and two actions.

Controller - > AController Action -> MethodA()

Controller - > BController Action -> MethodB()

Both of these return xml data by a View(typedObject).

I want to add base 64 encoding before returning this output to the client. On MethodA and MethodB. And there might be some other methods that should be included in this encoding aswell.

Would there be any good way of accomplish an behavoir / treatment of the action result ?

Would it be best to add a custom Action Result for this ?

7016100 0 WPF Border Object Border CornerRadius different from Border Background CornerRadius

I have two Borders on top of each other. One with a BorderThickness but no background, the other one without a border thickness, but with a background. Both Borders have a CornerRadius of 3. The problem is that the corner of the Background of one of the Borders sticks out from behind the corner of the other Border.

Notice the grey protruding out from behind the blue at the corners.

Here is the XAML with the first border element having the background and the Border named FocusVisual having the BorderThickness.

<Grid x:Name="grid"> <Border Background="{TemplateBinding Background}" CornerRadius="3"> <Grid> <Border x:Name="MouseOverVisual" Opacity="0" Background="{StaticResource NuiFieldHoverBrush}" CornerRadius="3" /> <Border> <Grid> <ScrollViewer x:Name="PART_ContentHost" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" /> <ContentPresenter x:Name="PART_WatermarkHost" Content="{TemplateBinding Watermark}" ContentTemplate="{TemplateBinding WatermarkTemplate}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" IsHitTestVisible="False" Margin="{TemplateBinding Padding}" Visibility="Collapsed"/> </Grid> </Border> </Grid> </Border> <Border x:Name="FocusVisual" Opacity="0" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{StaticResource NuiFocusBrush}" CornerRadius="3" /> </Grid>

CornerRadius having a different effect on the Background and Border of a Border object seems like a bug in WPF.

I could add a BorderThickness to the Border with the Background and set the BorderBrush to the Background color, but this causes the child elements of that border to be pushed in by the BorderThickness. I can probably get around this by rearranging elements, but it is kind of a pain so I thought I would see if anybody has a better workaround.

I assume neither stream is a backing stream for the other; if it was you could just promote or update the files up/down the stream hierarchy.

Otherwise, you could try to Change Palette, though I'm not sure you can do that without a workspace.

23290347 0 How to get a list which contains at least all the values of another list?

I have the situation where a list must contains at least the values of another list. So imagine we have list A with values 1, 2, 3. This is the list with the required values.

List B has the values 1, 5, 6, 7
List C has the values 1, 2, 3, 4, 7
List D has the values 2, 5, 6

In this situation I only want List C, since this is the only list which contains the values 1, 2 end 3.

I've tried this, but this doesn't work since it is always true:

query = from doc in query let tagIds = from t in doc.Tags select t.Id where parameters.TagIds.Except(tagIds).Count() <= parameters.TagIds.Count() select doc;

And when using this:

 query = from doc in query let tagIds = from t in doc.Tags select t.Id where !parameters.TagIds.Except(tagIds).Any<int>() select doc;

I only get the lists where the list matches exactly the 'required' list.

My question is, how can I solve my situation in a Linq 2 SQL query?

16569293 0 MySQL: Limit by a group of rows, not by a row

I have a MySQL table like the following. The id and name fields are just here to help identify the row, l represents many other fields whit not relevant data, and lat and lng are used to find duplicated entries.

CREATE TABLE v (`id` int, `lat` int, `lng` int, `l` varchar(3), `name` varchar(8)) ; INSERT INTO v (`id`, `lat`, `lng`, `l`, `name`) VALUES ( 1, 12, 12, 'a', 'group1-1'), ( 2, 12, 12, 'b', 'group1-2'), ( 3, 13, 12, 'c', 'single1'), ( 4, 13, 13, 'd', 'group2-1'), ( 5, 13, 13, 'e', 'group2-2'), ( 6, 13, 13, 'f', 'group2-3'), ( 7, 10, 13, 'g', 'group3-1'), ( 8, 10, 13, 'h', 'group3-2'), ( 9, 11, 12, 'h', 'group4-1'), (10, 11, 12, 'h', 'group4-2'), (11, 10, 14, 'i', 'group5-1'), (12, 10, 14, 'j', 'group5-2'), (13, 10, 14, 'j', 'group5-3') ;

Now I want to get all rows where there is more than one row with the same lat and lng values (let's call that a group):

SELECT v.* FROM v INNER JOIN ( SELECT lat, lng FROM v GROUP BY lat, lng HAVING COUNT(*) > 1 ) AS vg USING (lat, lng) ORDER BY name ;

Outputs:

ID LAT LNG L NAME 1 12 12 a group1-1 2 12 12 b group1-2 4 13 13 d group2-1 5 13 13 e group2-2 6 13 13 f group2-3 7 10 13 g group3-1 8 10 13 h group3-2 9 11 12 h group4-1 10 11 12 h group4-2 11 10 14 i group5-1 12 10 14 j group5-2 13 10 14 j group5-3

Works well so far, all but the "single1" rows are selected and ordered by group.

Now I want to add a limit to form different pages of this data. But all rows of the same group need to be on the same page (but not one page per group and it doesn't matter how many rows actually are on one page - just not too many). I don't see this done with a LIMIT statement, so I started to write my own:

SET @grp := 0, @last_lat := '', @last_lng := ''; SELECT * FROM ( SELECT v.*, @grp := IF((@last_lat = lat) && (@last_lng = lng), @grp, @grp + 1) AS grp, @last_lat := lat AS llat, @last_lng := lng AS llng FROM v INNER JOIN ( SELECT lat, lng FROM v GROUP BY lat, lng HAVING COUNT(*) > 1 ) AS vg USING (lat, lng) ORDER BY lat, lng ) AS vv WHERE grp BETWEEN 0 AND 7 ORDER BY grp ;

This query whit out the WHERE part outputs this data:

ID LAT LNG L NAME GRP LLAT LLNG 1 12 12 a group1-1 6 12 12 2 12 12 b group1-2 6 12 12 5 13 13 e group2-2 7 13 13 6 13 13 f group2-3 7 13 13 4 13 13 d group2-1 7 13 13 7 10 13 g group3-1 8 10 13 8 10 13 h group3-2 8 10 13 10 11 12 h group4-2 9 11 12 9 11 12 h group4-1 9 11 12 13 10 14 j group5-3 10 10 14 11 10 14 i group5-1 10 10 14 12 10 14 j group5-2 10 10 14

The idea is to change the values in the line WHERE grp BETWEEN 0 AND 7 for each page. But the numbers from the group don't start at 1 and I can't see why (and that makes it unusable for the first page). The Start number is different depending on how many group are in the whole data. So what I need to have, is that the grp column start whit 1 and then continues whit always +1.

What is wrong with this query and are there any better ways to do this?

You can play whit this query here: http://sqlfiddle.com/#!8/86d3c/2

Minimax with Alpha-beta pruning that Lirik mentioned is a good place to start, but it takes some time to wrap your mind around if you're not familiar with it.

Alternatively you can think about how you would play the game if you had a perfect memory and could do fast calculations and try to implement that. The upside is that's usually easier to understand.

Minimax would probably result in shorter but more difficult to understand (for those unfamiliar with it) code that depending on the game, could result in playing a perfect game if the game is simple enough (however it also has the disadvantage of favoring not losing to winning because it assumes the opponent will be playing perfectly as well)

Since it sounds like it's a game of complete information (the whole board is visible to all players at all times) a properly implemented Minimax with infinite look-ahead could give an AI that would never lose (assuming infinite computation time). In games using Minimax the difficulty level is often determined by how many moves ahead the algorithm looks at. It gets exponentially slower the more steps there are, so you will run into a hardware limitation if the game isn't super simple (which is why there isn't a perfect Chess playing AI yet, I think last I checked it would take a couple thousand years on the fastest computer at the time of the article I read, sorry no citations)

While I have not managed to figure out why there were so many ReaderWriterLock instances in the finalizer queue, I did find a solution to my problem and got rid of them.

Calling DataSet.Dispose did not help. Therefore I have started reusing existing DataSet instances instead of keep creating new ones because 'someone said that DataSet.Clear is slow' - it is not (if at all) in a long run. This approach completely removed the issue with the finalizer queue instances.

Answering question 2, with pandas 0.18.0 you can do:

store = pd.HDFStore('compiled_measurements.h5') for filepath in file_iterator: raw = pd.read_csv(filepath) store.append('measurements', raw, index=False) store.create_table_index('measurements', columns=['a', 'b', 'c'], optlevel=9, kind='full') store.close()

Based on this part of the docs.

Depending on how much data you have, the index creation can consume enormous amounts of memory. The PyTables docs describes the values of optlevel.

I use that code to make the new button and tring move him. Now I want to move it around the form.

If i do that just to one button, I can move it, but if it's more then one, that is a problem.

If someone could give the code,fix him or just help me it will be very good for me! tnx :)

You can use subqueries to get what you want, for example:

SELECT * FROM (SELECT INs.catid AS CategoryID, INs.subcatid AS SubcategoryID, SUM(INs.quantity) AS QuantityIN FROM in_stock INs GROUP BY INs.catid, INs.subcatid) AS a LEFT JOIN (SELECT OUTs.catid AS CategoryID, OUTs.subcatid AS SubcategoryID, SUM(OUTs.quantity) AS QuantityOUT FROM out_stock OUTs GROUP BY OUTs.catid, OUTs.subcatid) AS b ON ( a.subcategoryid = b.subcategoryid ) AND ( a.categoryid = b.categoryid );

From this, it is very easy indeed to edit and modify the query using the Query Design Window in MS Access

SELECT a.categoryid, a.subcategoryid, a.quantityin, b.quantityout, [quantityin] - [quantityout] AS RemainingQuantity FROM (SELECT INs.catid AS CategoryID, INs.subcatid AS SubcategoryID, SUM(INs.quantity) AS QuantityIN FROM in_stock INs GROUP BY INs.catid, INs.subcatid) AS a LEFT JOIN (SELECT OUTs.catid AS CategoryID, OUTs.subcatid AS SubcategoryID, SUM(OUTs.quantity) AS QuantityOUT FROM out_stock OUTs GROUP BY OUTs.catid, OUTs.subcatid) AS b ON ( a.subcategoryid = b.subcategoryid ) AND ( a.categoryid = b.categoryid );

I'm not sure if I make sense, maybe there are easier ways.

I am building a web app, which will be based in Bootstrap models, what I want is to display a model to make CRUD operations to my database.

For example I will have a models like these:

public class Author { public int id { get; set; } public string Name { get; set; } } public class Book { public int id { get; set; } public string Name { get; set; } }

What I want is to make a partial view that will display a dialog (modal) to add a new author to my app, same with books, and my 'n' classes my app will have, I want to render these partials wherever I need them. So I can add an author from any view of my page.

That part is ok, now I am having some 'troubles' because when I make an ajax post call to save my author in my data base I am facing that I already had a #Name field which was the one rendered for my books modal now when I call my field with jQuery, like this: $('#Name').val() it will grab the first #name.

That is easy to solve I will make a #AuthorName and a #BookName.

Now I am scared that my application will not be stable if my name system is not.

So is there any way to make an name system?

I am not sure how to do this but I would like to write my id's like this:

 @Html.TextBoxFor(u => u.Id, new { @id = "@MyDialogs.Authors.Add.Name" })

that will return something like this: dialogs-authors-add-namefield

Is this possible or I am being too lazy?

Why don't you query the database once to catch all information? Take a look at this:

connect(); $sql = 'SELECT gameid, mizbanid, mihmanid, score1, score2, gamedavar, gamestadium, now FROM games WHERE gameweek = ' . $site_week . ' ORDER BY now ASC LIMIT 9'; $query = mysql_query($sql); if(mysql_num_rows($query)) { while($Result = mysql_fetch_object($query)) { //loop trough results print_r($Result); //prints the results. echo $Result->gameid; //this is how you echo the data } }

Be aware that the mysql_query function is deprecated and needs to be replaced by mysqli :) .

10008125 0 SSRS Report, How do I have Group By on the Columns

In MS SQL 2008 R2 DB, I have a table:

Name, Value, Type A, 1, T1 B, 2, T1 C, 3, T1 D, 4, T1 A, 10, T2 B, 20, T2 C, 13, T2 D, 45, T2 A, 11, T3 B, 22, T3 C, 33, T3 D, 44, T3

What I want to do is to get this:

Name, Type T1, T2, T3 A, 1, 10, 11 B, 2, 20, 22 C, 3, 13, 33 D, 4, 45, 44

From the query, I can return this: Name, Value, Type A, 1, T1 B, 2, T1 C, 3, T1 D, 4, T1

A, 10, T2 B, 20, T2 C, 13, T2 D, 45, T2 A, 11, T3 B, 22, T3 C, 33, T3 D, 44, T3

Now I want to take this data and in SSRS, transform it into this form:

Name, Type T1, T2, T3 A, 1, 10, 11 B, 2, 20, 22 C, 3, 13, 33 D, 4, 45, 44

Types can change from one execution to another.

14141043 0 Resolving an ambiguous reference

I'm trying to create a manager class to use with my charting tool, the problem is the tool I use, uses the same names for both a 3d and 2d charts which is resulting in ambiguous reference when I try to add the 2d library.. any ideas how best to resolve this?

For example,

using tool.2dChartLib; using tool.3dChartLib;

BorderStyle is a member of both of these

I've tried casting the areas where I use BorderStyle. I suppose it could work if i just reference tool but then that would mean I'd have hundreds of tool.class lines instead of class

22507099 0 Seeing if value at first index is a number

I am working on a Wordpress site where 100,000+ spam accounts have been made. Although there are other types as well but many of them seem to have a user name that starts with a number.

So I wanted to ask whether there can be a MYSQL query to select/delete all users whose username starts with a number.

An extension to this question is that whether those users need to be deleted from the users table only or also the user-meta or other tables.

Any help appreciated.

Try escaping the .. with something like:

Uri target = new Uri("ftp://ftpserver.com/%2E%2E/AB00000/incoming/files");

That works according to this blog which I found in this discussion.

You must use string formatting to substitute variable for its value

cursor.execute("UPDATE `ISEF_DB`.`attendance` SET `present`='1' WHERE `id` = '%s'" % data)

Although be warned that this leaves you susceptible to SQL Injection. To prevent that you can use exceute like so (from the docs)

cursor.execute("UPDATE `ISEF_DB`.`attendance` SET `present`='1' WHERE `id` = '%s'", (data,))

i.e. pass the values as tuples to execute. More information about avoiding SQL injection when using MySQLDB can be found in this question

Update:

Just realized that I've misread your question as you are looking for methods defined via the Flex ExternalInterface class rather than those of the Shockwave ActiveX control itself; I'm gonna keep my original answer below as it might still be helpful regarding SWF usage via C# in general.

Concerning ExternalInterface I don't have an answer right now, but you might look into Fun with C# and the Flash Player 8 External API to get an idea on how to use this API via C# in the first place. (Another helpful sample might be Use External Interface of Flash 8 in Python and C# Applications.)

From what I'm reading in the former article there is likely no straight forward solution and the calling conventions via passing crafted XML fragments to CallFunction() are somewhat quirky, still you should be able to translate Georges solution to this in principle (as I said, it's likely not gonna be pretty ;)

Good luck!

How to access a SWF from .NET via COM Interoperability:

SWF for Windows is implemented by means of the Adobe Flash Player ActiveX control, consequently you would use it from .NET via COM Interoperability.

You can find a (legacy) article/sample regarding this on Adobes site, see Embedding Macromedia Flash Player in a C# Application to Display Stock Information for an overview (please note the introductory note of the article regarding unavailability of the sample code), but see below.

More specifically you can find the initial steps you need to take to achieve your goal on another page of this article, see Embedding and Communicating with the Macromedia Flash Player in C# Windows Applications - in particular please follow the article/steps up to and including section Making the Macromedia Flash Player ActiveX Control Available Within Visual Studio .NET.

Once you have completed the outlined steps to add the Shockwave ActiveX control to your toolbox and to a particular projects references you can simply double click this reference (named ShockwaveFlashObjects in Visual Studio 2008), which will open the Visual Studio object browser highlighting the assembly Interop.ShockwaveFlashObjects; then navigate down into the namespace ShockwaveFlashObjects, where you'll find, amongst others, the interface IShockwaveFlash, exposing (depending on your view filter) all its members, including the desired external methods with their respective C# signatures.

You can try using AttachAware and it's attach method. You should implement AttachAware interface in your decorator and/or component.

Here's link to Angular.dart docs - https://docs.angulardart.org/#angular-core-annotation.AttachAware

To change the styling of a ShadowDom component you can use element.shadowRoot to get the root of your web component. Shadow root is almost like 'document' object. You can use shadow root to get reference to any element and then you can easily modify it by applying styles as needed.

You could use something like this.element.shadowRoot.querySelector('[some-attr]').innerHtml = "Modified by decorator" // disclaimer: not tested, but I hope you get the idea.

In Pentaho EE 5.1 due out sometime this half of the year analyzer will have native mongo support - but that is only EE.

Your other option is indeed to use a SQL layer, and optiq is a good choice for that. The Saiku guys have got mondrian running via optiq to Mongo - and have even built support for aggregations. Note: The native Pentaho support mentioned above does NOT use optiq.

Unfortunately there's few other options at this stage!

The m// and print commands are separate commands joined by an &&.

Within a regex \2 is a backreference to the second capture, which will be assigned to the $2 variable after the regex has finished matching. Outside the regex \2 is meaningless; only $2 is a variable that can be accessed. See here for more info: http://perldoc.perl.org/perlretut.html#Backreferences

When reading that link, note that after Perl 5.10 \2 is still recognized but \g2 is encouraged. This is because \11 is ambiguous.

I have a wellformatted excel file with a lot of macros and styling in it that I want to keep. Then i have this information I want to enter in the file. And I want to do it with ruby.

I've tried roo and spreadsheet but they don't seem able to actually edit the file, just create a new one and loosing all the formattin in the process.

It feels it should be simple to just edit the cells I want and save the file again but obviously it's more complex that I originally though(or I'm completely blind)

I'm learning ruby at the moment so that's why I would prefer a solution in ruby. If you know there are better suited laguages for this feel free to point me in the right direction and I'll check it out.

31665095 0 Xcode error compiling c++ Expected member name or ';' after declaration specifiers

I'm having issues with the checking methods in a c++ library (openNN) i'm trying to compile in Xcode. I'll use an example of one of the methods as i suspect they are all caused by the same issue.

Header declaration where i get the error:

If i change the definition in the header to
void InverseSumSquaredError::check(void) const;
I end up with the error:
Extra qualification on member 'check'

I'm currently using the dialect C++98 and Library libc++. Xcode is set to compile sources as Objective-C++ which takes care of most of the other errors.

I can't think of anything else relevant to this issue, it's had me stumped for hours, so any type of help is much appreciated.

alarm() is not a good way to implement periodic events in a server. It functions as an asynchronous signal, and as such is difficult to handle appropriately while something else is going on. For instance, if your server is in the middle of sending a message to a client, having the alarm go off and start generating output would be likely to disrupt the message. Bottom line is, it's not the right way of going about this.

Most client/server applications use the select() or poll() system calls at their core. These system calls allow your application to wait for an event to occur (e.g, data arriving) on any number of file descriptors, with an optional timeout. This is how most server applications handle connections with multiple clients at a time.

Using these system calls is likely to require you to restructure your application around a "state machine" model, rather than using program flow to represent state. Explaining how to do this effectively is a larger task than is reasonable for a short answer such as this; prepare to do some research!

Approach #1: Generic case

One approach with bsxfun and matrix-multiplication -

mask = bsxfun(@ge,indx_pos,event_start.') & bsxfun(@le,indx_pos,event_end.') Etotal = energy.'*mask

This could be a bit memory-hungry if indx_pos has lots of elements in it.

Approach #2: Non-overlapping start/end ranges case

One can use accumarray for this special case like so -

%// Setup ID array for use in accumarray later on loc(numel(pos))=0; %// Fast pre-allocation scheme valids = event_end+1<=numel(pos); loc(event_end(valids)+1) = -1*(1:sum(valids)); loc(event_start) = loc(event_start)+(1:numel(event_end)); id = cumsum(loc); %// Set elements as zeros in HitEnergy that do not satisfy the criteria: %// pos>0.7 & pos<2.0 HitEnergy_select = (pos>0.7 & pos<2.0).*HitEnergy(:); %// Discard elments in HitEnergy_select & id that have IDs as zeros HitEnergy_select = HitEnergy_select(id~=0); id = id(id~=0); %// Accumulate summations as done inside the loop in the original code Etotal = accumarray(id(:),HitEnergy_select);

36609375 0 How to pass parameters to child router in Angular 2 for deep linking?

Basically, if I have one component that signals a child routing component, like:

@RouteConfig([ { path: '/users/...', //CHILD ROUTING COMPONENT name: 'Users', component: UsersComponent, useAsDefault: true } ]) export class App { constructor(private _router: Router) {} ucFirst(str:string){ var parts = str.split(' '); for(var i = 0, ilen = parts.length; i < ilen; i++){ parts[i] = parts[i].charAt(0).toUpperCase() + parts[i].slice(1); } return parts.join(' '); } ngOnInit() { //Handle deep links if exist var baseHref = document.getElementsByTagName('base')[0].href; var path = location.href.replace(baseHref, ''); if(path.length){ let slugs = path.split('/'); for(let i = 0, ilen = slugs.length; i < ilen; i++){ slugs[i] = this.ucFirst(slugs[i]); } this._router.navigate(slugs); } } }

And then the child router uses some kind of parameter in one of the paths, like:

@RouteConfig([{ path: '/', name: 'UserList', component: UserListComponent, useAsDefault: true },{ path: '/:id', name: 'UserView', component: UserViewComponent }])

How do I make deep links work? I can use the code to get to the grandchild view, but deep links fail (Error No route 'users/1' where 1 is the :id). Basically I need to handle half of the path in the parent router and half in the child router but I have not found the way to do so. I can make deep links work as long as they exist completely in the parent but I am working on a larger project and want to make the set up more modular.

I have put my code in this plunker: https://plnkr.co/edit/7cKBEwQmFSJrDFWhL4EV?p=preview It works locally (minus the deep links) but not on plunker, which I've never used before so I imagine this is kind of simple configuration issue on my part. But it at least gives you an idea of the attempt at modularization.

The button allows us to go full screen for browser. How come I can revert it to normal on click again?

Javascript

<script type="text/javascript"> function goFullscreen(id) { // Get the element that we want to take into fullscreen mode var element = document.getElementById(id); // These function will not exist in the browsers that don't support fullscreen mode yet, // so we'll have to check to see if they're available before calling them. if (element.mozRequestFullScreen) { // This is how to go into fullscren mode in Firefox // Note the "moz" prefix, which is short for Mozilla. element.mozRequestFullScreen(); } else if (element.webkitRequestFullScreen) { // This is how to go into fullscreen mode in Chrome and Safari // Both of those browsers are based on the Webkit project, hence the same prefix. element.webkitRequestFullScreen(); } // Hooray, now we're in fullscreen mode! } </script>

I would recommend you to use

editoptions: { maxlength: 8}

instead of the custom validation which you use. In the case the input element will be created with the maxlength attribute directly. So the user will not able to type more as characters as specified by maxlength.

UPDATED: You can't change the interface of any callback function, but you can do share common code of different custom_func in the following way. You define your custom validation function having three parameters like

function validLen (value, colName, valueLength) { if (value.length === valueLength) { return [true, ""]; } else { return [false, "fail"]; } }

and use it in the following way

{ name: 'cntrct_id', editrules: { custom: true, custom_func: function (value, colName) { return validLen(value, colName, 8); } }

If you need to use this inside of custom_func then you can change return validLen(value, colName, 8); to return validLen.call(this, value, colName, 8);.

The error is on .val() The code finds 2 elements and then it can't take the value. If I remove .val() I get it saying it is an [Object HTMLInputElement]

The error is

Note:

I Know that I can get this code to work by doing the following:

var teamOne = ""; var teamTwo = ""; var children = $(this).find(".team-url"); if (children.length === 2) { teamOne = children.first().val(); teamTwo = children.last().val(); } alert(teamOne + " - " + teamTwo);

You can have multiple http inbound-endpoints with the same hostname and port, but different paths. Here's a simple example I tested:

<flow name="Flow" doc:name="EchoFlow"> <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8084" path="services/hello" /> <cxf:jaxws-service port="80" serviceClass="mypackage.ServiceInterface" /> <component class="mypackage.ServiceClass" /> </flow> <flow name="Flow2" doc:name="EchoFlow2"> <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8084" path="services/goodbye" /> <cxf:jaxws-service port="80" serviceClass="mypackage.ServiceInterfaceTwo" /> <component class="mypackage.ServiceClassTwo" /> </flow>

Here we're hosting two web services; both endpoint URLs start

http://localhost:8084/services/

but have different endings (hello and goodbye). The ServiceInterface class looks like this:

package mypackage; import javax.jws.WebMethod; import javax.jws.WebService; @WebService public interface ServiceInterface { @WebMethod String sayHello(String name); }

And the ServiceClass looks like this:

package mypackage; import javax.jws.WebService; @WebService(endpointInterface = "mypackage.ServiceInterface") public class ServiceClass implements ServiceInterface { public String sayHello(String name) { return "Hello "+name; } }

ServiceInterfaceTwo and ServiceClassTwo are the same, but instead of sayHello() it has sayGoodbye().

I just went through this myself.

My number one tip is to not try and change everything on day one. You need friends if you really want to be able to fix this thing. You need your colleagues respect before you suggest how to change everything they've been working on for months (years?).

First, get the code under version control as soon as possible. If that's not going to be easy for you, at least start making daily backups, even if it means just zipping up the files and naming the zip file with the date. If nobody there knows about version control, buy a Pragmatic Programmer's book on CVS or SVN, and set it up yourself. The books can be read in a day, and you can be up and running quickly. If nobody else wants to use version control, you can use it yourself... then when somebody loses a file you can save the day with a copy from your repo. Sooner or later the others will see the wisdom that is version control.

Second, dive into the code as hard as you possibly can. Live it and breathe it for a month. Show the people who are there that you are going to learn their code.

Third, as you go through the code, take copious notes. Write down every thing that bothers you about the code. Just get your thoughts on paper. You can organize it later, after Month One.

Fourth, install a code profiler (such as xdebug). That'll tell you what files & functions are being called on each page, and how long each piece of code takes to run. You can use this to figure out your includes issues, and find slow bits of code. Optimize those first.

After your month of hard work, sifting through the code, and taking notes, turn your notes into a proper document. The different sections could range from security, to caching, to architecture, to whatever else is bothering you. For every criticism you make, offer a better solution, and an estimate on how long it would take to fix. This is where you get rid of all the competing javascript frameworks etc.

Revise this document as much as possible. I cannot stress that enough.

Make sure your audience can tell you're doing it for the good of the company, not just your personal preferences.

Present it to your boss, in person. Set-up a time to discuss it.

They could fire you for having written it. If they do, you're better off without them, because they don't want to improve, and your career will stagnate.

They might want to implement all of your recommendations. It's not likely, but it is possible. Then you'd be happy (unless your recommendations fail).

Most likely they'll want to implement a few of your recommendations, and that's better than nothing. At the very least, it'll help ease your concerns.

As for testing, setup another "virtual host" in Apache (supported on both Windows & Linux). Virtual Hosts let you run multiple sites on a single server. Most larger sites have at least 3 virtual hosts (or actual servers): dev.domain.com (for daily development), staging.domain.com (for QA people to do testing on just before a release), and www.domain.com (your production server). You should also setup dev, staging, and production versions of the database, with different logins & passwords so you don't accidentally confuse them.

An alternate solution would be to give each developer their own virtual host on the Linux server, and they can work via FTP/SCP or network share using samba.

Good luck!

19524400 0 network sync a looping gstreamer videos

I am trying to frame sync two looping videos over a lan. Both videos have the same length but the resolution might differ. The following code works already for the first run:

server code

client code

As soon as the video reaches GST_MESSAGE_EOS it starts over which is fine. But the client however will keep on reaching EOS all the time. I think this is because the servers clock is already past the clients video length.

How can I fix this. Can I somehow reset the servers base time on EOS? And if so how?

28351953 0 Deploy Laravel on 1&1 Servers

I have recently completed my first laravel site, but now I am stuck with deployment. This is an entirely new concept for me. My webspace is supplied by 1&1.

I have attempted several tutorials, but none seem to work. Based on the tutorial here at: Uploading Laravel Project onto Web Server

I structured my server folders like so:

(note when first FTPing my server, there was no www or html_docs, only a logs folder).

enter image description here

In the www, my index.php was altered to:

require __DIR__.'/../laravel/bootstrap/autoload.php'; $app = require_once __DIR__.'/../laravel/bootstrap/start.php';

In the laravel/bootstrap/paths.php file I altered:

'public' => __DIR__.'/../../www',

When visiting my domain in a browser, for example: myDomain.co.uk - the site is redirected to a "placeholder" (named /defaultsite) page for 1&1 domains and states "This domain name has just been registered."

If I append /www/index.php for example, I get file does not exist, even though the file is residing in my structure above.

As you probably noticed I am very new to server side aspects such as FTPing ect. I have read a few tuts, and all seem to take a different approach, leaving me confused to the best method. I am not sure where to go from here, so any advice is appreciated. Thank you.

Edit: I think I actually got it working, but now when I go to domain.com/public I get what I think is a DB error:

SQLSTATE[HY000] [2002] No such file or directory.

Any Advice please?

Assuming that the menu screen has sky and ground (i.e. that stuff isn't part of the game), then so far so good. Looks like you have the actors in separate classes, which is good. "MenuScreen" is the sort of thing that would make sense as a single responsibility.

26057790 0 Redis key not removed even after Resque job completes successfully

Here is my scenario, i'm using resque to queue a job in redis, the usual way its done in ROR. The format of my key looks something like this (as per my namespace convention)

"resque:lock:Jobs::XYZ::SomeCreator-{:my_ids=>[101]}"

The job runs successfully to completition. But the key still exists in redis. For a certain flow, i need to queue and execute the job again for the same parameters (the key will essentially be same). But seems like the job does not get queued.

My guess is that since the key already exists in Redis, it does not queue the job again.

Questions:

Is this behavior of resque normal (not removing the key after successful completition)?

If Yes, how should i tackle this scenario (as per best practices)?

If No, can you help me understand what is going wrong?

Assuming you have some unique index on the table, this works great:

book = Book.first Book.delete_all(book.attributes)

If you don't have a unique index on the table, the above is dangerous - you could nuke more rows than anticipated. If that is the case, either add a unique index on an existing column (or columns) or else add a PK to the table.

33389805 0 How to avoid lots of if-else in javascript (nodejs)

Based on a parameter, function should select a json file out of more 100 json and fire a query to other system.

There will lots of query around in hundreds.

Obviously if else and switch won't be manageable. I took a look for strategy patten in the javascript.

var queryCode = req.param('queryCode'); if(queryCode == 'x'){ //do something } else if( queryCode == 'y'){ //do something } else if( queryCode == 'z') { //do something }

// do something might become large sometimes...
so I want to replace it something like strategy pattern. Which will be the best design. Thanks in advance for any suggestion for this problem.

10804598 1 Global variable messes up my recursive function

I've just run into a tricky issue. The following code is supposed to split words into chunks of length numOfChar. The function calls itself, which makes it impossible to have the resulting list (res) inside the function. But if I keep it outside as a global variable, then every subsequent call of the function with different input values leads to a wrong result because res doesn't get cleared.

Can anyone help me out?

Here's the code (in case you are interested, this is problem 7-23 from PySchools.com):

res = [] def splitWord(word, numOfChar): if len(word) > 0: res.append(word[:numOfChar]) splitWord(word[numOfChar:], numOfChar) return res print splitWord('google', 2) print splitWord('google', 3) print splitWord('apple', 1) print splitWord('apple', 4)

I believe there are three different concepts: initializing the variable, the location of the variable in memory, the time the variable is initialized.

First: Initialization

When a variable is allocated in memory, typical processors leave the memory untouched, so the variable will have the same value that somebody else stored earlier. For security, some compilers add the extra code to initialize all variables they allocate to zero. I think this is what you mean by "Zero Initialization". It happens when you say:

 int i; // not all compilers set this to zero

However if you say to the compiler:

 int i = 10;

then the compiler instructs the processor to put 10 in the memory rather than leaving it with old values or setting it to zero. I think this is what you mean by "Static Initialization".

Finally, you could say this:

 int i; ... ... i = 11;

then the processor "zero initializes" (or leaves the old value) when executing int i; then when it reaches the line i = 11 it "dynamically initializes" the variable to 11 (which can happen very long after the first initialization.

Second: Location of the variable

There are: stack-based variables (sometimes called static variables), and memory-heap variables (sometimes called dynamic variables).

Variables can be created in the stack segment using this:

int i;

or the memory heap like this:

int *i = new int;

The difference is that the stack segment variable is lost after exiting the function call, while memory-heap variables are left until you say delete i;. You can read an Assembly-language book to understand the difference better.

Third: The time the variable is initialized

A stack-segment variable is "zero-initialized" or statically-initialized" when you enter the function call they are defined within.

A memory-heap variable is "zero-initialized" or statically-initialized" when it is first created by the new operator.

Final Remark

You can think about static int i; as a global variable with a scope limited to the function it is defined in. I think the confusion about static int i; comes because static hear mean another thing (it is not destroyed when you exit the routine, so it retains its value). I am not sure, but I think the trick used for static int i; is to put it in the stack of main() which means it is not destroyed until you exit the whole program (so it retains the first initialization), or it could be that it is stored in the data segment of the application.

if it's only calculating pairs of 2 (and no higher), you can simply count the other two arrays.

for anyone in array1, simply count(array2) + count(array3) = number of pairs

Maybe a possibility for you is to cache your data as real PHP. The function var_export provides you with the PHP representation of data. It has some limitation, which serialize does not have when it comes to circular references, but on the other hand it is way easier to understand, because you already know the syntax.

The code you gave was almost there. I needed the same thing for my code. I added information to the cookie (last time modified) and compare that to the current time. If there is enough space in between (in this case 1 second) then modify the cookie info. This works even if you have 15 tabs open.
I took out the check for whether they have cookies turned on.

$(function(){ resetCookies(); setTimeout(checkTime, 1000); }); function resetCookies(){ setCookie("loginTime",'10',1); } function checkTime() { var arrloginTime=getCookie("loginTime").split("--"); var loginTime=arrloginTime[0]; var dtmLastMod=new Date(arrloginTime[1]); console.log(loginTime); if (loginTime!=null && loginTime!=""){ var dtmNow = new Date(); if ((dtmNow.getTime() - dtmLastMod.getTime()) >= 1000){ var newTime=loginTime-1; if(newTime==0){ autoLogout(); return false;} setCookie("loginTime",newTime,1); } }else{ autoLogout(); return false;} setTimeout(checkTime, 1000); } function setCookie(c_name,value,exdays){ var exdate=new Date(); var dtmLastMod = new Date(); exdate.setDate(exdate.getDate() + exdays); var c_value=escape(value) + "--" + dtmLastMod + ((exdays==null) ?

The input parameter is a string array which was stored in char*, when you get arg[1], it just return the string array (char*), if you ouput it, the whole string will be ouput. But if you convert it ot string, it just convert the memory address of the paramter to int, so you will just see the address result.

You are hiding your adMobBannerView in your displayiAdsOrNot function. This function is called every time the viewWillAppear. Remove this and you should get the results you desire.

As for the rest of your code, you have a lot going on here. First, to simplify things you should move all of your code that is creating and laying out your adBanner and adMobBannerView under viewWillAppear when [[NSUserDefaults standardUserDefaults] boolForKey:@"IAPSuccessful"] is false, and set both banners .hidden = YES automatically. This will eliminate the need for your displayiAdsOrNot and displayAdMobBannerOrNot where you are repeating a lot of the same if statements checking for IAP and which device the user is using. After doing this, in your delegate methods you can simply hide or show the correct banner depending on if iAd fails or not now. For example, iAd loads so set its hidden value to NO and AdMob’s to YES, and vice versa if iAd fails to load an ad. I’m sure you were checking the IAP every time in case the user purchased it while in the current session so you could remove the ads. An easier solution would be to move the ads outside of the screen bounds on completion of the IAP and then on the next launch of your application simply do not create either banner at all if [[NSUserDefaults standardUserDefaults] boolForKey:@"IAPSuccessful"] is true. A few other things to point out are, you should remove your request.testDevices AdMob request before submitting your application, and it seems you are defining your NSLayoutConstraint *myConstraint multiple times. I’m not exactly sure what you’re trying to do here. Also, in didFailToReceiveAdWithError you have self.adBanner.hidden = true, it should be self.adBanner.hidden = YES.

Are you using models? Code igniter doesn't enforce this, but using models in addition to controllers and views is a good way to have a shorter controller function. Alternatively, you could place some of the functions in your own helper, then import it.

And if you want to set some default values for the entire constructor, you can use the class constructor. This is outlined here:

You can now do this with JSONModel.

Assume we have the following model:

@class MyModel @property (strong, nonatomic) NSString *name; @property (strong, nonatomic) NSArray *products; @end

If the complete JSON doc looks like this:

{ "productType1": { "name": "foo", "products": [] }, "productType2": { "name": "foo", "products": [] }, "productType3": { "name": "foo", "products": [] } }

then you should use one of the [MyModel dictionaryOfModelsFrom...]; methods.

If it looks like this:

{ "productTypes": { "productType1": { "name": "foo", "products": [] }, "productType2": { "name": "foo", "products": [] }, "productType3": { "name": "foo", "products": [] } } }

Then you should use another model like this:

@class MyModelContainer @property (strong, nonatomic) NSDictionary <MyModel> *productTypes; @end

Use agrep function.

Initial data:

x <- c("Company A Pty.","BigData GMBH","Company A Pty. Ltd.","Red Pants Warsaw", "Company A Georgia", "Red Pants Ltd", "BlueSocks House")

first argument is pattern that you want to look in data (eg x[1]), second is where you want to look, max is the max distance two strings can differ. value means that we want to obtain strings instead of indexes of vector.

If there is no match, you can change max, but be careful! More is not always better.

agrep(x[1],x, max=0.1, value=TRUE) ## [1] "Company A Pty." "Company A Pty. Ltd." agrep(x[1],x, max=0.3, value=TRUE) ## [1] "Company A Pty." "Company A Pty. Ltd." "Company A Georgia" agrep(x[1],x, max=0.7, value=TRUE) ## [1] "Company A Pty." "Company A Pty. Ltd." "Company A Georgia" "Red Pants Ltd"

What's more, this is not symetrical. "Red Pants Warsaw" (x[4]) was not matched to "Red Pants Ltd" (x[6]) but it worked other way - x[6] was matched to x[4]. Be aware of this.

agrep(x[4],x, max=0.2, value=TRUE) ## [1] "Red Pants Warsaw" agrep(x[6],x, max=0.2, value=TRUE) ## [1] "Red Pants Warsaw" "Red Pants Ltd"

5579426 0 Mandatory and Non mandatory in non identifying relationships

With reference to the last part of answer given here: What's the difference between identifying and non-identifying relationships?

A non-identifying relationship can be optional or mandatory, which means the foreign key column allows NULL or disallows NULL, respectively.

I am creating a non-identifying relationship in MySQL Workbench and whether I keep foreign key column MANDATORY or NON-MANDATORY, has no effect. Even if it is NON-MANDATORY I can't enter NULL values in it. I have to explicitly choose that particular foreign key as allowing NULL and only then I am able to store NULL values.
So I want to ask if this is the correct behaviour or this is a problem with MySQL Workbench or MySQL?

Thanks

Random numbers have certain special properties. Computer memory in general doesn't satisfy those properties.

If I sampled computer memory, tons of it would be quite similar, and certain numbers would have such a low probability of existing, that they might not even be found within the entire memory of a computer.

That's not to mention that if I read a bit of memory that's outside of the memory allocated to a program, the OS will kill me dead with a SEGFAULT.

It's a bad idea, on many levels. Use a proper random number generator.

The odd part is the template works well on my computer, but not on the colleague's. The vendor has already optimized the template to be good for Outlook 2010.

On my colleague's computer, it seems like the template has added additional padding between the images or table cells. The email she'll eventually send out will have this additional padding as well.

Is there any settings I need to do on her Outlook 2010 settings?

You got the entire logic correct, except one minor flaw. You have idxR as a logical matrix. Hence colonies is a logical matrix too. Therefore, you get the expected output till the second-last line. Problem occurs on the last line, when you try to assign an array of numbers in which each number is greater than 1 (colonies(colonies==1).*ret;) to a logical matrix.

Elements greater than 1 are clipped to one and thus you see only zeros and ones. There is a simple workaround. Change the first line to

colonies = double(idxR);

P.S. The answer was right in front of you, you just didn't spot it. You had written:

I tried this code in a new file and assigned a matrix with random ones and zeros to idxR and then it seems to work.

The idxR matrix must have been of double datatype, if you used randi.

22213313 0 Perl - is "uc" enable to use when return to a variable?

Just a simple question I want to ask. I am beginner for Perl script, sorry if you feel this question is stupid.

The question is can I return a variable and apply "uc" when return.

Here is the code:

my $desc = ""; @names = ("thor-12345-4567"); $size = @names; Thor(); print $desc; sub Thor() { if ($size ne "0") { return uc ($desc=$names[0]); } $desc = "NA"; return $desc; }

I just want to know that is "uc" can be use when we return to a variable?

When I try to print $desc, it did not return to uppercase.

Thank you very much!

Your problem is not occuring at the GROUP BY level, but rather in the JOIN. The rows with a NULL qualifier cannot be JOINed and, because you're using INNER JOIN, they fall out of the result set.

Use LEFT OUTER JOIN to see all the rows.

I use rails_admin

One of my partial is like this :

%b= questionnaire.title - CSV.parse(questionnaire.content, :headers => true, :col_sep => ",") do |row| - row.to_hash.each do |key, value| = succeed value do %b= key + " : "

but key is sometimes like this "I_dont_want_underscore"

but then I've got this error showing : Can't convert frozen string (or something like this) Then I tried to duplicate

But then server does not respond anymore...how come ? finally I tried to put a def in my application_helper.rb

def sub_underscore self.dup.gsub!-'_',' ') end

and

Use CSS media queries as follows. In your handlebars template:

<div class="show-ipad"> {{outlet "ipad-outlet1"}} {{outlet "ipad-outlet2"}} </div> <div class="show-iphone"> {{outlet "iphone-outlet1"}} {{outlet "iphone-outlet2"}} </div>

In your stylesheet (media-queries taken from this article):

/* iPads (portrait and landscape) ----------- */ @media only screen and (min-device-width : 768px) and (max-device-width : 1024px) { .show-iphone { display: none; } } /* Smartphones (portrait and landscape) ----------- */ @media only screen and (min-device-width : 320px) and (max-device-width : 480px) { .show-ipad { display: none; } }

Adapt the media-queries to your needs (targeting iPads in landscape, in portrait, etc.).

In Javascript don't assume anything about the client device. Just render all outlets for all devices, and let the CSS media-query handle what is shown and what is hidden.

35185257 0 UITableView ContentSize when using dynamic height on UITableViewCells

I've been searching for this for many hours but didn't find a way to make it.

I have a UITableView whose UITableViewCells use AutomaticDimension for Height:

tableView.RowHeight = UITableView.AutomaticDimension; tableView.EstimatedRowHeight = 160f;

The problem is when I try to get tableView's ContentSize. It seems to be calculated based on EstimatedRowHeight instead of the current height of its rows. Suppose, if there are 10 Cells then ContentSize's returned value is 160x10.

Then my question is if there is a way to do this.

24678934 0 Audio Playing Badly when Online

I've created this game using Javascript, and I play all sounds (including effects and background music) using the Audio type. It works perfectly when I run the page from my computer, but after I uploaded on my host and tried to run from the web, it started to sounds really terrible: sometimes it is delayed, sometimes it does not play at all.

I've noticed that the main problem is related to playing the same audio more than once in a short amount of time: it plays a shooting sound whenever the user clicks on the page, so usually it isn't that bad when they're not spamming their mouse, but once you start clicking many times the sounds turns out terrible.

The audio file for that particular sound is very short, and when running from my computer is has no problem even when the user is clicking very fast. Here is what the function does:

function play(aux,volume){ if(volume == undefined) volume = 1; if(!sound){return;} aux.volume = globalVolume * aux.customVolume * volume; aux.load(); aux.play(); }

So, pretty much, what it does is loading and playing the sound again whenever that function is called. That was made so it would start again even if the the function is called while the sound was still going on.

Again, this whole things works smoothly when running from my computer, but from the web it just sucks.

Q: Does anyone knows how to fix this? Or does anyone know an alternative I could use to make it work?

Suggestions are welcome as well.

851314 0 Selecting an entity doesn't subselect associated entities

I'm learning ASP.NET MVC (and MVC in general) and all the help online I find only demonstrates using a single table, not relations between multiple tables. I'm running a query that I expect should also return associated entities, but it's not and can't figure out what I'm missing. I appreciate your help!

I have the following data:

Ticket TicketID CompanyID Subject ... -------- --------- ------- 1 1 "stuff" 2 1 "things" Company CompanyID Name ... --------- -------- 1 "FredCo"

So every ticket is linked to a specific company. I am trying to create a Details view for Tickets, and I want to display the company name. Here is what I have set up at the moment.

Model

A Ticket entity and a Company entity, and there is an association called CompanyTicket between them. The navigational properties are Ticket.Company and Company.Tickets.

In the mapping details for the association, I have:

Maps to Ticket Company.CompanyID <-> CompanyID Ticket.TicketID <-> TicketID

Controller

My TicketController.Details method looks like this:

public ActionResult Details( int id ) { var tickettoview = ( from m in _db.Ticket where m.TicketID == id select m ).First(); return View( tickettoview ); }

Edit: After going through Mark Hamilton's suggestion, I realize the problem is my query. Putting a breakpoint on the return shows that tickettoview never has Customer populated. So this narrows it down, but I'm still not sure how to populate the Company attribute.

Again, thank you!

I've got two approaches for you:

Firstly using Activator.CreateInstance

public static IEnumerable<TV> To<TU, TV>(this IEnumerable<TU> source) { return source.Select(m => (TV) Activator.CreateInstance(typeof(TV), m)); }

Secondly, you could use interfaces to define properties rather than use parameterized constructors:

public interface IRequiredMember {} public interface IHasNeccesaryMember { IRequiredMember Member { get; set; } } public static IEnumerable<TV> To<TU, TV>(this IEnumerable<TU> source) where TV : IHasNeccesaryMember, new() where TU : IRequiredMember { return source.Select(m => new TV{ Member = m }); }

The first method works but feels dirty and there is the risk of getting the constructor call wrong, particularly as the method is not constrained.

Therefore, I think the second method is a better solution.

The problem is that you are using a normal pointer to store your EqVector. When you map a shared memory segment, it maybe mapped into any location in the process's address space. This means that where eqVector is stored in memory is different in the first process' memory space than in the second process'. You need to use a boost::offset_ptr, which stores addresses as offsets from the beginning of shared memory segments, see here: http://www.boost.org/doc/libs/1_35_0/doc/html/interprocess/offset_ptr.html

I just used a simple regex. Of course, my answer is in python 2.7 so this may not work for you, depending on the version of python you are using.

input = '' with open('input.xml', 'r') as input_file: input_file = open('input.xml', 'r') input = input_file.read() import re output = re.sub('\n\s*([^<> ]+)\s*\n\s*', '\\1', input, flags=re.MULTILINE) with open('output.xml', 'w') as output_file: output_file.write(output)

Here's a working repl: http://repl.it/1SG/3

EDIT

This will not work if your values contain greater than or less than signs. I'm not sure how XML works entirely but it may not even allow those characters as values anyway.

In UrlManager, It will search from Top to Down.

So upto my knowledge, you can not define two CONTROLLER/ACTION for same Url alias.

But you can use controller forward in siteController. If your condition not satisfy then forward to mediaController.

$this->forward('media/index');

Hope helps !!

You can add 1 (= one day) to the time difference, then calculate it directly using TimeValue to remove the date part:

ShiftDuration = TimeValue(CDate(#06:00:00 am# - #10:00:00 pm# + 1)) ShiftDuration = TimeValue(CDate(#10:00:00 pm# - #02:00:00 pm# + 1)) ShiftDuration = TimeValue(CDate(#02:00:00 pm# - #06:00:00 am# + 1))

All of these will return a date/time value (a timespan) of 08:00:00 which can format for display using Format as you like or convert to hours and/or minutes.

If you need to display durations of more than 24 hours, use a function like this:

Public Function FormatHourMinute( _ ByVal datTime As Date, _ Optional ByVal strSeparator As String = ":") _ As String ' Returns count of days, hours and minutes of datTime ' converted to hours and minutes as a formatted string ' with an optional choice of time separator. ' ' Example: ' datTime: #10:03# + #20:01# ' returns: 30:04 ' ' 2005-02-05. Cactus Data ApS, CPH. Dim strHour As String Dim strMinute As String Dim strHourMinute As String strHour = CStr(Fix(datTime) * 24 + Hour(datTime)) ' Add leading zero to minute count when needed. strMinute = Right("0" & CStr(Minute(datTime)), 2) strHourMinute = strHour & strSeparator & strMinute FormatHourMinute = strHourMinute End Function

30056571 0 Why is Android Studio taking it's time to launch an app on the device

When I was using Eclipse with the ADT plugin and I clicked on launch, it almost instantly launched the app on my device.

I've switched to Android Studio because I wanted the gradle build system (I know that is available in Eclipse, but Android Studio itself is easier)

But when I click launch in Android Studio, it takes about 2 to 4 times longer than using Eclipse. I'm not working at a company so nobody is bothering, but my work is definitely slowed down by this.

Why is Android Studio slower than Eclipse? Because of the Gradle building system?

38534312 0 In Firebase 3.0 together with Angularjs, it seems onAuthStateChanged fires on every route change. Is that expected?

I have an app using Firebase and Angularjs. If I put a listener on onAuthStateChanged, it seems to fire every time I navigate to a new url in my site, and the Angularjs Route changes. This seems undesirable/incorrect? Anyone else experience this? E.g. if I do this in a controller:

 firebase.auth().onAuthStateChanged(function(user) { if (user) { alert("changed"); } });

every time the route changes the alert pops up.

Since the logged in state of the user doesn't seem to be changing, why would this listener fire? I think I am missing something. Anyone understand what's going on?

There are two ways. The quick way to is to change the __unicode__ return for your TestTable to return the field you like. However you might only want to show that field in current form but not other places, so it's not ideal.

Second option, you could define you own form field. It inherits ModelChoiceField, but override label_from_instance method:

class TestTableModelChoiceField(forms.ModelChoiceField): def label_from_instance(self, obj): # return the field you want to display return obj.display_field class TestForm(forms.ModelForm): type = TestTableModelChoiceField(queryset=Property.objects.all().order_by('desc1'))

20981637 0 Reflective capabilities of R7RS Scheme

The R7RS report on the programming language Scheme describes two ways of running Scheme code in a Scheme system:

1) A scheme system can run a program as described in section 5.1 in the report.

2) A scheme system can offer a read-eval-print-loop, in which Scheme code is interpreted interactively.

My question is on how these two ways of running Scheme code can be reflected inside a Scheme system with what's included in the R7RS report.

There is the eval library procedure eval, which executes Scheme code inside a running Scheme system so eval looks like what I am searching for.

However, the only guaranteed mutable environment I can plug in eval is the environment returned by the interaction-environment repl library procedure. With this, however, I cannot reliably simulate a REPL (point 2) from above) because a REPL allows the import form, which the eval procedure does not have to.

Also, I cannot use the interaction environment for evaling a full Scheme program by other reasons: It is generally not empty, in particular it contains all bindings of (scheme base).

For realising 1) inside a running Scheme system, the eval library procedure environment looks promising as it allows to import libraries beforehand (which is part of running programs). However, the environment is immutable, so I cannot evaluate defines inside the environment. A way out would be to wrap the body of the program to be run in a lambda form so that define would define local variables. However, this also doesn't work: Inside a lambda form all defines have to come at the beginning of the body (which is not true for the top-level of a Scheme program) and inside a lambda form library bindings can be lexically overwritten, which is not possible by top-level bindings.

As Scheme is Turing-complete, I can, of course, simulate a Scheme system inside a running Scheme system but I am wondering whether it is possible just by using the eval procedure. One reason for my interest is that eval might be optimized (e.g. by a JIT compiler backend), so using this procedure might give near native speed (compared to writing a simple interpreter by hand).

3655746 0 Where to begin learning about audio processing?

I've tried looking up how I might go about this for a while now, and maybe I am using the wrong terminology in my searches or it's way too advanced for me. I basically want to be able to analyze audio files in real-time. I know hardly anything about audio processing so I should probably start small and work my way up. Eventually I'd like to be able to display a power (or frequency?) spectrum correlating to audio playing in real time. Basically like the WinAmp spectogram (terminology?)

Any online tutorials with perhaps an API suggestion or two would be greatly appreciated. I've found some vague explanations (mostly dealing with calculating FFT's then converting them to something...) Like I said, I know little of audio processing, so knowing where to start would be great.

Language of choice: C++

netstat information can be retrieved by calling the GetTcpTable and GetUdpTable functions in the IP Helper API, or IPHLPAPI.DLL. For more information on calling the IPHLPAPI.DLL from Delphi, check out this Network traffic monitor. There are some wrappers for it too, and it is part of JEDI API Library.

I wrote a Delphi version of NetStat long ago, but have since lost the source code. Those resources should get you started though.

I think this is an implementation detail of the Linux file system. While on Windows .h and .H files are effectively the same, on Linux you can have a traditional.h and a traditional.H in the same directory.

If I am understanding you correctly, you just need to specify the capital H in the files that include your headers.

Disclaimer: Do not down vote without explaining why, because OP didn't include his entire code base or hardware/infrastructure design. But if i've made critical errors in my code or logic, explain them and down vote accordingly.

Lets start off with defining the bottle-necks you'll encounter (some obvious, some not).

Harddrives - They're slow and doesn't cache large quantities
Re-reading the same data multiple times
Memory, you can't store a 13GB file, or maybe you do and that's an option?

To solve these, you could go multiple routes.

One clear benefitial way would be to read the large data into a database (postgresql or mariadb for instance). But I'll assume this isn't at all possible for now.

In regards to a CSV reader, they're fine but maybe not so efficient.
Since you're going to read through both files anyway I would consider the following:

Read the 13GB file line by line and save the ID in a dictionary without checking if the key/value exists. (why? Because checking if the value exists is slower than just overwriting it and dictionaries also has a added bonus that keys are unique so duplicates will be weeded out) or add it to a set() as described by many others.

followed by reading the smaller file line by line and checking your dict or set if it contains the ID.

`dict()` vs `set()` vs `list()`

Here's a comparison between the three data types set(), list() and dict():
code used: test.py

(11.719028949737549, 999950, 'Using dict() for inserts') (1.8462610244750977, 'dict() time spent looking through the data') (11.793760061264038, 999961, 'Using set() for inserts') (7.019757986068726, 'set() time spent looking through the data') (15min+, 'Using list()') # Honestly, I never let it run to it's finish.. It's to slow.

As you can see dict is marginally quicker than set, while list() just falls behind completely (see description of why by Antti). I should point out my data is a bit skewed since it's a quick and dirty demo of the speed difference, but the general idea should still come across.

Using dict() as a solution

So if you do not have access to a database version of the source-data, and you need to use Python, id go with something along the lines of:

delimiter = b'\x01' big_source = {} with open('13_gig_source.log', 'rb') as fh: for line in fh: csv = line.split(delimiter) big_source[csv[4]] = None # 5:th column, change to match CUSTOMER_ID output = open('result.log', 'wb') with open('smaller_file.log', 'rb') as fh: for line in fh: csv = line.split(delimiter) if csv[4] in big_source: output.write(csv[4] + b'\n') output.close()

Since I didn't know which column the data exists on i didn't optimize the split().
For instance, if it's the last column you're trying to fetch, do line.rsplit(delimiter, 1)[-1] instead. Or if it's the 3:d column do line.split(delimiter, 3)[2] because it will abort the process of looking for the next position of the delimiter in the split() functions.

Using linux tools

Yes, some tools might be better off suited for this such as awk because of the fact that it's a specific tool written in C to perform a very specific task. Even tho Python is based on C it still has a lot of abstraction layers on-top of that C code and will for the most part be slower than the counterpart C tools written for specific tasks.

Now I have no data to test this with, nor am i a PRO With Nix-Commands or PWN-C for short. So I'll leave someone else to give you examples of this, but i found this:

merge two csv files according to matching rows and add new columns in linux

And it might be helpful.

6338456 0 sequentially including various View classes in a parent layout

I have a main layout in which I'd like to sequentially display / hide various custom layouts according to timers and user input.

In my example, I'd like the following timeline:

show an initial layout, created by the class MainStart. The user will click on the button when they're ready to start.
after the user clicks, we'll run a countdown timer, displaying the countdown to the screen. This is done by MainCountdown.
once the countdown is complete, MainLast is displayed. It has a button allowing the user to click "Again?" when they want to start over.
if the user clicks "Again?" then go to step 1.

According to this question, I may have to use removeView() and addView() to achieve what I want.

I pushed to GitHub a trimmed down version of what I want to do: Hide and Show Layouts so you can see everything, but the problem seems to boil down to myView still being visible after this:

myView = inflate(mContext, R.layout.main_start, _view_group); myView.setVisibility(View.GONE);

direct link to code on GitHub

direct link to related layout

Can I make a small change to my code/layouts to make the views hide/appear the way I want?

Am I completely Doing It Wrong?

No you can't see the parents local variables. You inherit the parents prototype chain, not their local state. In your case you're applying the parent function onto the child object which does not hold the state.

apply(this,...)

means that you're binding the function to the current value of this. when you call method b from the child object, its then bound to the child, and therefore is not operating within the closure that contains the parents value.

22802839 0 What type of relationship these two tables will have in laravel?

i have four tables in database:

users (for storing user details)
conversations (for storing conversations id).
conversationsmember (for storing conversations member)
conversationsreply (for storing conversations reply)

A user will have many conversations and each conversation will have its members and replies.

here are the details:

Users migration:

$table->increments('id'); $table->string('name', 32); $table->string('username', 32); $table->string('email', 320); $table->string('password', 64); $table->timestamps();

Conversations migration:

$table->increments('id'); $table->timestamps();

conversationsmembers migration:

$table->increments('id'); $table->integer('conversation_id'); $table->integer('user_id'); $table->timestamps();

conversationsreply migrations

$table->increments('id'); $table->integer('conversation_id'); $table->integer('user_id'); $table->timestamps();

Now in User model, i need to define relationship between users table and conversations table. As they are not directly connected, i used hasManyThrough relation.

..app/models/User.php

... public function conversations() { return $this->hasManyThrough('Conversation', 'ConversationsMember', 'conversation_id', 'id'); } ...

When i 'm trying to use it, it's showing a blank array.

If you are using c#, you can simplify your life and use two separate regex:

bool res = false; string str = // your string if (str < 8) { res = Regex.IsMatch(str, @"^[0-9]+$"); } else { res = Regex.IsMatch(str, @"^(?=[a-zA-Z0-9]*[a-zA-Z])[a-zA-Z0-9]*$"); }

char string[128]; defines a statically sized array of chars. There is no need to allocate memory for it, but, on the other hand, there is no way to resize the memory portion.

To use a dynamically sized array use char *string; with string = malloc(128), string = realloc(string, newsize) and free(string) when you are done.

Open a new Fragment when a gridView is clicked and then pass the position from the bundle parameters. Then in NewFragment show the listview and the data from database.

gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { NextFragment nextFrag= new NextFragment(); Bundle bundle = new Bundle(); bundle.putInt("POSITION",position); this.getFragmentManager().beginTransaction() .replace(R.id.Layout_container, nextFrag,TAG_FRAGMENT) .addToBackStack(null) .commit(); } });

In the NextFragment get the reference of listView and then update the data from database using proper adapter.

Unexpectedly, but I've found an answer.

The only reason was in source-map package, which is in brunch dependencies.

I've tried only two last versions of brunch: 1.7.13 and 1.7.14. Both of them requires source-map version ~0.1.26. Which is for now resolved to 0.1.34 wherever you install brunch.

And this is a root of evil.

What I've actually did is manual replace 0.1.34 with 0.1.33, directly in global brunch/node_modules folder.

And that's it. After this everything magically fixed, and my sourcemaps point to right lines again.

Don't know WHY it is so - maybe, source-map@0.1.34 is broken. But this really works.

Source code analysis

There are consistency problems:

static pid_t P1, P2, P3; // PIDs for each process int P; // parent PID

Why is P and int instead of a pid_t? Why is it global instead of static? Why is it P instead of P0? Should the whole lot be an array?

static pid_t P[4];

(There would be benefits to using an array!)

There is repetition that should be in a function invoked multiple times:

// Sending PIDs to process 1 close(providePIDY1[0]); write(providePIDY1[1], &P, sizeof(int)); write(providePIDY1[1], &P1, sizeof(int)); write(providePIDY1[1], &P2, sizeof(int)); write(providePIDY1[1], &P3, sizeof(int)); close(providePIDY1[1]); // Sending PIDs to process 2 close(providePIDY2[0]); write(providePIDY2[1], &P, sizeof(int)); write(providePIDY2[1], &P1, sizeof(int)); write(providePIDY2[1], &P2, sizeof(int)); write(providePIDY2[1], &P3, sizeof(int)); close(providePIDY2[1]);

Note that there's also repetition because the P values aren't an array. There's also a possible portability liability; pid_t does not have to be the same size as int.

There are problems with checking inputs:

choice = getchar(); if(choice == 's')

Since choice is a char, you can get erroneous handling of EOF — if you bothered to test for it. You also leave a newline (at least) in the input, and don't skip leading spaces in the input. You'd likely do better with reading a line of data (fgets() or POSIX readline()) and then using if (sscanf(buffer, " %c", &choice) != 1) { …handle error… } to get the character.

Your next input block is curious:

printf("Which process is receiving the signal - 1, 2, or 3?: "); choice2 = getchar(); choice2 = getchar(); printf("\n"); if((choice2 < 1) && (choice2 > 3))

The first input reads the newline (assuming there were no trailing spaces, etc), and the second gets a '1', '2', or '3'. However, you test whether the input value is both less than 1 and greater than 3, and there's no known value in the universe for which both conditions are true (NaN values are unknown values). You really wanted something like:

if (choice2 < '1' || choice2 > '3')

After you've determined which signal to send (more or less), you have another block of repeated code because you used P1 etc instead of an array P.

There are chunks of repeated code in your child processes, such as the code that reads the process numbers. These should be in a function, too. The signal handling setup should probably be in a function too, though I've not spent a lot of time checking for the differences and similarities between the different process functions.

Major problem

You say the code is supposed to be processing arithmetic expressions. You have the main program loop reading choices about signal handling, but you seem to have process1() also trying to read expressions. This is bad news; it is indeterminate which of the processes will get to read any given input.

Back to the small stuff

You have:

dataSize = strlen(buff) + 1; // plus NULL if(dataSize > 0) write(pfd12[1], &dataSize, sizeof(int)); write(pfd12[1], &buff, sizeof(char)*dataSize);

The test is a little pointless; the minimum value that strlen() can return is 0, so the minimum value in dataSize is 1, so the condition will always be true. (Theoretically, I suppose, you could enter so much data that the size_t returned by strlen() overflows the int dataSize, but you've not allocated enough space for that to be an actual problem — your code will have had other problems before that.)

In process2(), this code is curious:

 token = strtok(buff, delim); while( token != NULL ) { number = strtol(token, &end, 0); if(!isInteger(number)) break; }

There are no circumstances under which the int number; is going to be a non-integer when you scan the string with strtol(). You have a risk of overflow (sizeof(int) != sizeof(long) on 64-bit Unix systems, for example). You have a risk of not being able to interpret the remnants of floating point value (because the . is not a valid part of an integer). You'll need to rework that code.

There's a lot of repetition in the signal handling code; it should be refactored so that you need fewer functions. It'll be easier to understand in the long run. Copy'n'paste'n'edit is a very bad way of programming when the result is near clones of the code in a single program.

I'm not clear what the differences are between the two versions you show; I've not scrutinized them. You should look at how to create an MCVE (How to create a Minimal, Complete, and Verifiable Example?) or SSCCE (Short, Self-Contained, Correct Example) — two names and links for the same basic idea. I'm not sure that either lot of code qualifies as an MCVE; both versions is overkill. Just supply the compilable code.

After compilation

I've compiled the second chunk of code (saved in a file called procsync.c) on my Mac running Mac OS X 10.10.3 with GCC 5.1.0, and using the command line:

$ gcc -O3 -g -std=c11 -Wall -Wextra -Wmissing-prototypes -Wstrict-prototypes \ > -Wold-style-definition -Werror procsync.c -o procsync $

To my considerable surprise, the code compiled under those very stringent options with no complaints — that is something I very seldom see in code on SO.

Congratulations!

(But there are still the other issues to worry about.)

2940823 0 generateUrl problem

I am trying to generate a url but I keep getting a strange warning even though it works. I am making an api xml page and I use the following call in the controller:

public function executeList(sfWebRequest $request) { $this->users = array(); foreach($this->getRoute()->getObjects() as $user) { $this->users[$this->generateUrl('user_show', $user, true)] = $user->asArray($request->getHost()); } }

The user_show route is as follows:

# api urls user_show: url: /user/:nickname param: { module: user, action: show }

And the xml outputs as follows:

So it outputs the correct xml but I do not know why it throws thows warning when calling the generateurl method.

With mapsforge you cannot do this. You have to use a routing library like graphhopper is one. See here how to use it: http://graphhopper.com/#developers.

But there are other offline and online routers as well. Have a look here: http://wiki.openstreetmap.org/wiki/Routing/offline_routers and here http://wiki.openstreetmap.org/wiki/Routing

For basic types like int, NoneType, dict and other simple cases there's a natural "factory" in Python - it is ast.literal_eval.

>>> import ast >>> ast.literal_eval('None') is None True >>> ast.literal_eval('{1: 2}') {1: 2} >>> ast.literal_eval('1e6') 1000000.0

So if your data is a superposition of basic types (something json-like for instance), then you can parse it with single ast.literal_eval call. Unlike exec and eval, ast.literal_eval is much safer as you can't run any code with it.

Try setting the setOnPreferenceChangeListener for your editPreference in onCreate(), put your validation code inside this callback.

Reading the docs, they say OnSharedPreferenceChangeListener is called when the shared preference is changed(is already changed). In the other hand the setOnPreferenceChangeListener is triggered "when this Preference is changed by the user (but before the internal state has been updated)"

4032071 0 Dealing with implementation concerns in TDD

I've just got started on TDD and very quickly ran into a brick wall. Here's my scenario... I'm trying to model an Image object, and going through the TDD steps I've started with a simple object which eventual grew into...

public class ImageObject { public string Name {get; set;} public int Width {get; set;} public int Height {get; set;} public bool IsValid() { //Some rules } }

Of course the obligatory tests...

[Test] public void ImageWidthCannotBeLessThanZero {...} [Test] public void ImageHeightCannotBeLessThanZero {...} and so forth...

So far so good. Next, I want to represent the physical file in the class somehow. It could be with a file path

public class ImageObject { public string Path {get; set;} }

or a series of bytes

public class ImageObject { public byte[] Bytes {get; set;} }

(Please this is not an argument about DB vs File system for storage.)

At this point I'm not feeling comfortable because my mind is drifting and starting thinking about the infrastructure/implementation details. Where is my flaw?? Should i make the decision upfront on the implementation detail? Do i need a clever design pattern to deal with this? Would a mocking framework help? This is an Object Analysis/Design problem and I should use UML tools? (Wait a minute i thought TDD was about design?)

Anyway how do i overcome this of problem? I want to remain focused on designing my objects and not think about infrastructure concerns at this time?

Your call to setAttribute uses the key "userbean", then your call to getAttribute uses urbean.getUser_mobile().

Unless urbean.getUser_mobile() returns "userbean" then getAttribute will return null.

Given the code setting the attribute is:

session.setAttribute("userbean", urbean);

The code to get the attribute should be:

User_Registration urbean = (User_Registration)session.getAttribute("userbean")

You have to use the same key to get that you used to set...

Could do with seeing a bit more context, but the following should do what I think you want:

Private Sub btnIgnorar_Click(sender As Object, e As EventArgs) Handles btnIgnorar.Click DialogResult = DialogResult.Ignore Close End Sub

This will close the dialog and return the associated result code to the caller. As to the original code, it seems a bit strange setting the values in the buttons click handlers?

There's nothing wrong with adding script elements mixed in the middle of the body, however if you want to improve loading times, you might want to append the script elements to footer.php. Having scripts called after the rest of the dom has loaded will prevent the loading of the scripts from blocking the rest of the page from rendering.

If it's a very small script, I see no reason not to just add them inline where it'll be easy to see what elements they affect.

It is useful to mark "unknown" or missing values.

For instance, if you're storing people, and one of the fields is their birthday, you could allow it to be NULL to signify "We don't know when he was born".

This is in contrast to having non-nullable fields where, for the same type of meaning, you would need to designate a "magic value" which has the same meaning.

For instance, what date should you store in that birthday field to mean "we don't know when he was born"? Should 1970-01-01 be that magic value? What if we suddenly need to store a person that was born on that day?

Now, having said that, NULL is one of the harder issues to handle in database design and engines, since it is a propagating property of a value.

For instance, what is the result of the following:

SELECT * FROM people WHERE birthday > #2000-01-01# SELECT * FROM people WHERE NOT (birthday > #2000-01-01#)

(note, the above date syntax might not be legal in any database engine, don't get hung up on it)

If you have lots of people with an "unknown" birthday, ie. NULL, they won't appear in either of the results.

Since in the above two queries, the first one says "all people with criteria X", and the second is "all people without criteria X", you would think that together, the results of those two queries would produce all the people in the database.

However, the queries actually say "all people with a known and definite criteria X."

This is similar to asking someone "am I older than 40?" upon which the other person says "I don't know". If you then proceed to ask "am I younger than 41?", the answer will be the same, he still doesn't know.

Also, any mathematics or comparisons will produce NULL as well.

For instance, what is:

SELECT 10 + NULL AS X

the result is NULL because "10 + unknown" is still unknown.

This library will probably make things a lot easier for you: https://code.google.com/p/php-csv-parser/. I have used it in a recent project where I need to parse CSVs and insert into a MySQL database.

You can choose which table to insert into by using $csv->getCell($x, $y) where $x and $y point the cell with "Table1" or "Table2" inside.

So you could do:

$table_name = $csv->getCell($x, $y); if( $table_name === "Table1" ) { // code to insert into table 1 } else if( $table_name === "Table2" ) { // code to insert into table 2 }

13731744 0 cannot debug into my DbContext derived class code using Entity Framework (ver 4.3.1) code-first

Here is my solution setup using VS 2012 Ultimate:

I have a project (e.g. MyDomainModel) containing all the business domain types using POCO classes. I have another project (e.g. MyEntity) referring to the MyDomainModel project and has the derived DbContext class (e.g. MyDbContext) implementing custom business logic (e.g. for automatic time-stamping when inserting and modifying data) in the SaveChanges method.

I have another mstest based project (e.g. MyEntity_Tests) which will test the derived DbContext (e.g. MyDbContext) with known seeded data as part of the database initialization.

My problem is that when debugging the test, the breakpoint set on the MyDbContext's c# code is not hit. However if I put lines such as Debug.Print("xxx") in the file and debugging the same test, the test output will contain those expected output "xxx".

I know that Entity Framework runtime will generate proxy dll behind scene to wrap those dlls (e.g. MyDomainModel.dll). However not being able to debug my own code as in MyDbContext is really a big problem to me. Do other people have the similar problem when using EF code-first and how to solve this problem?

So this problem arose because of inexperience with the express module.

I thought bodyParsed would hold a value returned from: app.use(bodyParser.json());

when you use app.use(bodyParser.json()); It actually stores it in the body property of the Request.

So:

app.use(bodyParser.json(joptions));//causes request.body to populate with the JSON data app.use(bodyParser.urlencoded({ extended: true })); // for parsing application/x-www-form-urlencoded requires multer app.all('/*', function(request, response){ //Handle request var bucket = request; console.log('\n \n \n &&&&&& \n \n \n'); var joptions = { type: 'application/json' } console.log(request.body)); var headParsed = parseHttpHeader(bucket.headers['content-type'])[0]; console.log(headParsed); });

Not sure if this forces all requests to be parsed as application/json. Maybe moving the bodyparser inside the app.all() will cause it to only parse when using that route?

The image on a UIImageView is an UIImage optional, meaning that it can have a value (contain an image) or it can be nil.

So, when you're saying:

let ocrSample = myImageView.image

your ocrSample is now an UIImage optional, which you then have to unwrap before you use it.

When you then say:

tesseract.image = ocrSample!.fixOrientation().g8_blackAndWhite()

you are force unwrapping your ocrSample by using !, meaning that you are telling the compiler to just unwrap and use the optional, regardless of it being nil or not. This causes a crash when you then try to use that unwrapped optional if it contains nil.

What you can do is unwrap ocrSample using an if let like so:

func checkWithOCR() throws{ if let ocrSample = myImageView.image { tesseract.image = ocrSample.fixOrientation().g8_blackAndWhite() if(tesseract.recognize()){ let recognizedText = tesseract.recognizedText if recognizedText != nil{ print("recognizedText: \(recognizedText)") let trimmedText = String(recognizedText.characters.filter { !" \n\t\r,".characters.contains($0) }) myImageView.image = tesseract.image convertCurrency(Float(trimmedText)!) //convert the tesseract text } } SwiftSpinner.hide() } else { //No value could be found, do your error handling here } }

Here:

if let ocrSample = myImageView.image

you are trying to unwrap the value of myImageView.image into ocrSample, if that succeeds, then you know for sure that ocrSample is not nil and can use it onwards. If it fails, then you can do your error handling, show an alert view and whatever else you need to do.

Hope that helps you.

You need to call rect for each colour that you want to draw, and have those colours in a categorical column in your data frame so that you can filter the data per category for each call to rect.

I don't know what your original data is like, so here's something similar:

# set up simple plotting window plot.new() plot.window(xlim=c(0,6),ylim=c(0,8)) # example data. Using colour as the categorical value we will filter on sample.d <- data.frame(x=c(3,4,5,6), yb=c(1,3,5,7), yt=c(0,2,4,6), colour=c("black","black","red","red")) # draw black rectangles black.d <- sample.d[sample.d$colour == "black",] rect(0, black.d$yb, black.d$x, black.d$yt, col="black") # draw red rectangles red.d <- sample.d[sample.d$colour == "red",] rect(0, red.d$yb, red.d$x, red.d$yt, col="red")

You need to set an expectation on the UsarioService to say what will be returned when usarioService.save(...) is called.

Before getting to that point, you need to say in the test mockUsarioService.createMock() which will create the actual instance of the mock object, that's what you will pass to the controller usarioService attribute. Copied the code below from the Grails documenation. http://grails.org/doc/1.1/guide/9.%20Testing.html

 String testId = "NH-12347686" def otherControl = mockFor(OtherService) otherControl.demand.newIdentifier(1..1) {-> return testId } // Initialise the service and test the target method. def testService = new MyService() testService.otherService = otherControl.createMock()

I'm one of the AeroGear JS devs. The JS OTP lib is just getting started, but we have both Android and iOS libs that are more mature and since you are using cordova/phonegap it's possible to create a plugin to access the native libs until the JS version is a bit more solid.

It is not possible, to return a vector c(4, 'not possible', 3, 'not possible') as such a vector does not exist. All elements in a vector must be of the same type. Off course you can output numbers an texts together. This is a simple exercise that can be solved in a number of ways. For teaching purposes, I propose the following, where the two problems are divided into two functions in a very functional manner:

getSingleRoot <- function(x){ if(x<0){ cat("not possible ") return(NaN) } else{ cat(sqrt(x)) cat(" ") return(sqrt(x)) } } getRoot <- Vectorize(getSingleRoot) a <- getRoot(c(4, -4, 9, -16))

Other good solutions could make use of a for Loop, of Map, of ifelse or sapply, on sqrtalready being a vectorized function and so on. Ìf this is homework, it depends on what you have already learned.

Turning comment into answer since it turned out to be the solution:

In your shader code you have a varying variable called LightDirection_cameraspace, which you use in your fragment shader computations. But you never assign a value to it in the vertex shader (instead you compute a local variable LightPosition_cameraspace which isn't used further, though). So it probably has some undefined value inside the fragment shader, causing your lighting issues.

33553915 0 aria-describedby text not announced on

by JAWS

I have an HTML form with mainly 2 types of fields - text and checkboxes groups. Each form field has a hidden that includes error message and connected to formfield with "aria-describedby". When form with errors is hit submit button, common error message shows up on top and culprit fields gets error styling at field level. As user tabs to errornous form to edit, to each field, field level error message is also displayed via CSS changes. If JAWS is running, it is read out as user tabs into field.

But this is not happening for checkboxes group. I have checkboxes wrapper - tabbable, user can Kb focus to it and error div is displayed but not announced.

We do not have aria-live and alert on each form field but on common error message div on top. This is on purpose as we want those errors to be announced first by JAWS as user hits save.

Any suggestions to this problem? I tried to have tabindex and aria-describedby /aria-invalid on outer div or on another wrapper div but failed to fix jaws issue.

<div style="display: none; left: -9999px; z-index: 1000; top: 335.717px;" class="errorClass" id="showerror">Error: Please select a checkbox </div <div> <fieldset aria-describedby="showError" aria-invalid="true" id="myFieldSet" tabindex="0" > <legend>some legend text</legend> <div class="checkboxClass"> <input type="checkbox" id="1" value="1" name="chkgp"> <input type="checkbox" id="2" value="2" name="chkgp"> </div> </fieldset> </div></div>

To maintain state across activities you have to use SharedPreferences, or database. In your case SharedPreferences is the best option

You have used OnSavedInstance it will only save the instance until the activity is not destroyed i.e it stays on the stack.

Check activity lifecycle to understand more about when an activity is destroyed.

For each checkbox you can store its value in sharedPreference and on onCreate() of you activity you should check the checkboxes according to the sharedPreference values

Here is how you use shared prefs

SharedPreferences prefs= context.getSharedPreferences("myPrefs", 0); SharedPreferences.Editor editor = prefs.edit(); editor.putBoolean("checkbox1", true);//true if checked editor.commit(); // get stored value , if no value is stored then assume its false prefs.getBoolean("checkbox1", false);

Linear Diophantine equations take the form ax + by = c. If c is the greatest common divisor of a and b this means a=z'c and b=z''c then this is Bézout's identity of the form

enter image description here

with a=z' and b=z'' and the equation has an infinite number of solutions. So instead of trial searching method you can check if c is the greatest common divisor (GCD) of a and b (in your case this translates into bx - dy = c - a)

If indeed a and b are multiples of c then x and y can be computed using extended Euclidean algorithm which finds integers x and y (one of which is typically negative) that satisfy Bézout's identity

enter image description here

and your answer is:

a = k*x, b = k*y, c - a = k * gcd(a,b) for any integer k.

(as a side note: this holds also for any other Euclidean domain, i.e. polynomial ring & every Euclidean domain is unique factorization domain). You can use Iterative Method to find these solutions:

Iterative method

By routine algebra of expanding and grouping like terms (refer to last section of wikipedia article mentioned before), the following algorithm for iterative method is obtained:

1 . Apply Euclidean algorithm, and let qn (n starts from 1) be a finite list of quotients in the division.
2 . Initialize x0, x1 as 1, 0, and y0, y1 as 0,1 respectively.
- 2.1 Then for each i so long as qi is defined,
- 2.2 Compute xi+1 = xi−1 − qixi
- 2.3 Compute yi+1 = yi−1 − qiyi
- 2.4 Repeat the above after incrementing i by 1.
3 . The answers are the second-to-last of xn and yn.

pseudocode:

function extended_gcd(a, b) x := 0 lastx := 1 y := 1 lasty := 0 while b ≠ 0 quotient := a div b (a, b) := (b, a mod b) (x, lastx) := (lastx - quotient*x, x) (y, lasty) := (lasty - quotient*y, y) return (lastx, lasty)

So I have written example algorithm which calculates greatest common divisor using Euclidean Algorithm iterative method for non-negative a and b (for negative - these extra steps are needed), it returns GCD and stores solutions for x and y in variables passed to it by reference:

int gcd_iterative(int a, int b, int& x, int& y) { int c; std::vector<int> r, q, x_coeff, y_coeff; x_coeff.push_back(1); y_coeff.push_back(0); x_coeff.push_back(0); y_coeff.push_back(1); if ( b == 0 ) return a; while ( b != 0 ) { c = b; q.push_back(a/b); r.push_back(b = a % b); a = c; x_coeff.push_back( *(x_coeff.end()-2) -(q.back())*x_coeff.back()); y_coeff.push_back( *(y_coeff.end()-2) -(q.back())*y_coeff.back()); } if(r.size()==1) { x = x_coeff.back(); y = y_coeff.back(); } else { x = *(x_coeff.end()-2); y = *(y_coeff.end()-2); } std::vector<int>::iterator it; std::cout << "r: "; for(it = r.begin(); it != r.end(); it++) { std::cout << *it << "," ; } std::cout << "\nq: "; for(it = q.begin(); it != q.end(); it++) { std::cout << *it << "," ; } std::cout << "\nx: "; for(it = x_coeff.begin(); it != x_coeff.end(); it++){ std::cout << *it<<",";} std::cout << "\ny: "; for(it = y_coeff.begin(); it != y_coeff.end(); it++){ std::cout << *it<<",";} return a; }

by passing to it an example from wikipedia for a = 120 and b = 23 we obtain:

int main(int argc, char** argv) { // 120x + 23y = gcd(120,23) int x_solution, y_solution; int greatestCommonDivisor = gcd_iterative(120, 23, x_solution, y_solution); return 0; }

r: 5,3,2,1,0,

q: 5,4,1,1,2,

x: 1,0,1,-4,5,-9,23,

y: 0,1,-5,21,-26,47,-120,

According to Google’s documentation about their usage of canonical, it’s supported.

While support isn’t mentioned on Google’s documentation about their usage of prev/next, support was confirmed in a thread on their product forums.

Option 1:
I think that from the select efficiency point of view, option 1 might give you the best result, using a filtered index on the userId column in the UserScan table.

Option 2:
Your second option is probably the worst option since it means you will have two almost identical table structures in your database, and that's a bad design.

Option 3:
On the academic level, option 3 is the way to go. Nullable columns are frowned upon in the relational model. To prevent the UserScanEvent table from creating a many to many relationship between scans and persons, add a unique constraint on the scanId column. this way, each scan in this table can only be associated with a single person.

To sum up:
Having said all that, Select efficiency is a tricky thing to predict. My hunch tells me that option 1, while might not be the best fit to the relational model, will enable faster select executes then option 3, but as Jorge Campos wrote in his comment, it is merely my opinion, it's not something I can say for sure.

10684657 0 DataGrid not displaying data

I am trying to display a DataGrid on my mobile application after reading a CSV file and processing it. Here is what I have so far:

private void btOpenFile_Click(object sender, EventArgs e) { try { // Process all data into an array of Object // this.records array contains objects of type MyRecord // Create datatable and define columns DataTable dt = new DataTable("myDt"); dt.Columns.Add( new DataColumn("String A",typeof(string))); dt.Columns.Add( new DataColumn("Int 1", typeof(int))); // Loop through and create rows foreach(MyRecord record in records) { DataRow row = dt.NewRow(); row[0] = record.stringA; row[1] = record.int1; dt.Rows.Add(row); } // Create dataset and assign it to the datasource.. DataSet ds = new DataSet("myDs"); ds.Tables.Add(dt); dataGrid.DataSource = ds; dataGrid.Refresh(); } catch (Exception ex) { MessageBox.Show("Error: " + ex.Message,"Error"); } }

All I get is a blank data grid component when running my application. Can somebody point out my mistake? or how to do this correctly?

1851781 0 Transpose a row into columns with MySQL without using UNIONS?

I have a table that is similar to the following below:

 id | cat | one_above | top_level | 0 'printers' 'hardware' 'computers'

I want to be able to write a query, without using unions, that will return me a result set that transposes this table's columns into rows. What this means, is that I want the result to be:

 id | cat | 0 'printers' 0 'hardware' 0 'computers'

Is this possible in MySQL? I can not drop down to the application layer and perform this because I'm feeding these into a search engine that will index based on the id. Various other DBMS have something like PIVOT and UNPIVOT. I would appreciate any insight to something that I'm missing.

Mahmoud

P.S.

I'm considering re-normalization of the database as a last option, since this won't be a trivial task.

Thanks!

21691360 0 Camel and MQTT Route

I am working on a project and have decided to use Camel and ActiveMQ. I am attempting to create a route using Java and MQTT endpoints. Within this route I have also incorporated a Processor. This is what my route looks like:

from("mqtt:test?subscribeTopicName=zaq.avila.send") //.process(new RestProcessor()) .to("mqtt:test?publishTopicName=zaq.avila.receive");

From my understanding, the route is consuming from zaq/avila/send, a processor is applied and then the message is published to zaq/avila/receive. The to() part does not appear to be happening, when I check the console, I see that the processor executes though no message is published to zaq/avila/receive. Also, within the web console I see that the messages in zaq/avila/send for enqueued and dequeued increment even when I only pusblished one message. In addition, if I shutdown ActiveMQ I get the following:

 INFO | Waiting as there are still 1 inflight and pending exchanges to complete, timeout in 7 seconds.

Also:

 WARN | Error occurred while shutting down service: Endpoint[mqtt://test?publish TopicName=zaq.avila.receive]. This exception will be ignored. java.lang.NullPointerException

These exception make me wonder that the exchange is not completing and something is missing. I need help!

I tried:-

It sounds like there's a network issue preventing you from connecting to your Worklight server.

This can be due to many different reasons, to list some:

Poor WiFi/3G
Faulty device
Firewall issues on the network where the webserver is hosted
Worklight server issue

To ensure that you are indeed reaching the server I would suggest using a network sniffer. One tool that runs on Windows is Fiddler.

Fiddler can be set up as a reverse proxy where your device will be making calls to the proxy. The proxy will then route your request to the web server but it will also log the information so you can view it.

If you are on Windows, I would suggest installing Fiddler and following Option #2 of this answer.

You should then be able to see if your requests are reaching the server and continue investigation from there.

33342151 0 Laravel 5 - Auth Middleware dont protect route but throw error message

I have some problems with my auth middleware. I want to protect my routes with it, but in some controllers it dosent work really. If I check the routes as logout user, I got different error messasges instead of blocking the access and redirect to the login page. I use the middleware always over the __construct() in the controllers.

An example.

Controller

public function show(Dialog $dialog) { return $this->template($dialog, self::DISPLAY_MODE_DIALOG); } protected function template(Dialog $dialog, $displayMode, $messageLimit = 10) { $user = Auth::user(); // Check if the profile is currently controlled by the current user $isControlled = $dialog->moderator()->appProfile()->isControlledBy($user->id); $messageList = $dialog->latestMessages($messageLimit); return view('dialog.chat.template') ->with(compact('dialog', 'messageList', 'isControlled', 'displayMode')); }

Model

public function isAccessibleBy(User $user) { $profile = $this->moderator()->appProfile(); return $profile->isOwner($user->id) || $profile->isControlledBy($user->id); }

Error

Argument 1 passed to App\Model\Dialog\Dialog::isAccessibleBy() must be an instance of App\Model\Account\User, null given, called in C:\projekte\php\newchat\app\Model\Dialog\Dialog.php on line 332 and defined

Now I realize why this happens, but i think the middleware should dont show this messages an protecte the route.

http://laravel.com/docs/5.0/middleware

"However, if the user is authenticated, the middleware will allow the request to proceed further into the application."

14697454 0 Where can I get debug symbols (PDB) for Windows.Live.dll?

I am using the Microsoft Live SDK for Windows Phone to access SkyDrive and get an exception in Microsoft.Live.dll. I'd like to step through the source to debug the issue, but fetching symbols from symbol server http://msdl.microsoft.com/download/symbols fails.

I followed these instructions on how to set up the symbol server in my dev environment. The environment variable _NT_SYMBOL_PATH is set to srv*c:\symbols*http://msdl.microsoft.com/download/symbols. This seems to work for other assemblies. While debugging I see the symbol cache at c:\symbols grow with entries, but Microsoft.Live is missing.

Where can I get debug symbols for Microsoft.Live.dll?

3038834 0 Android - Persist file when app closes

I am creating a file in my Android application as follows:

HEADINGSTRING = new String("Android Debugging " + "\n" "XML test Debugging"); } public void setUpLogging(Context context){ Log.d("LOGGING", "Setting up logging....."); try { // catches IOException below FileOutputStream fOut = context.openFileOutput(FILE_NAME,Context.MODE_APPEND); OutputStreamWriter osw = new OutputStreamWriter(fOut); // Write the string to the file osw.write(HEADINGSTRING); /* ensure that everything is * really written out and close */ osw.flush(); osw.close(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally{ Log.d("LOGGING", "Finished logging setup....."); } }

And I write to the file during the running of the app as follows:

public void addToLog(File file, String text) throws IOException { BufferedWriter bw = new BufferedWriter (new FileWriter(file, true)); bw.write ("\n" + text); bw.newLine(); bw.flush(); bw.close(); }

This works fine but when my app closes the file gets deleted and when the app is run again all the information I wrote to it is gone.

How can I make sure the file persists even after closure of the app?

Update:

I have changed MODE_PRIVATE to MODE_APPEND and the problem is fixed, thanks Skirmish.

Both versions of your TransferText operation are using a SpecificationName named tblEmployees. What Code Page is specified in that Specification?

Try importing the text file manually. Choose "Advanced" from the Import Text Wizard. Then select Unicode in the Code Page list box. You may need to test with different Code Page selections until you find which one imports your text correctly.

Which ever Code Page selection works, save your choices as a specification and use it in your TransferText command, without supplying a separate CodePage parameter.

Any ideas? Exact same code, on the exact same server setup (Windows 2008 R2). With that said, could IIS be doing something?

I'm pretty sure you could just go over it to find out why this is happening. You could simply try to debug it, go through everything carefully and make sure everything works. With problems I encounter like that, I like to add excessive things to it, and then slowly whittle it down to where it works.

So, to sum it up, in your case, just to make sure, simply try str() to start with, and continue debugging from there.

MySQL is awfully lax when it comes to the GROUP BY-clause. In MySQL, you can add columns to your select clause that are not in the GROUP BY or an aggregate functions. Other RDBMS do not allow this, as it makes no sense semantically. MySQL just returns more or less random row values that fit the given query.

From the MySQL Doc

In standard SQL, a query that includes a GROUP BY clause cannot refer to nonaggregated columns in the select list that are not named in the GROUP BY clause. [...] MySQL extends the use of GROUP BY so that the select list can refer to nonaggregated columns not named in the GROUP BY clause.

What you have to do is, find out what the query is supposed to do and rewrite it.

Is using proxies a hard requirement? I wouldn't recommend proxies for general programming tasks as you can end up with unpredictable and hard-to-spot side effects.

If you keep to data and functions to transform it, avoiding mutable state where possible, I think you'll end up with simpler code that's easier to maintain.

var activities = ['reading', 'swimming']; var sfilter = function(activities){ return activities.filter(function(v){ return v[0] === 's'; }); }; console.log(sfilter(activities)); var memap = function(activities){ return activities.map(function(v){ return 'I am ' + v; }); }; console.log(memap(activities)); activities.push('smiling'); console.log(sfilter(activities)); console.log(memap(activities)); // Yes, I know this doesn't work in quite the same way, // but you're asking for trouble here since in your // code you're appending to one list, but overwriting // an element in the other. activities[1] = 'snoopying'; console.log(sfilter(activities)); console.log(memap(activities));

Stick to a Single Source of Truth and observe that. With each copy you are multiplying state complexity. That will make debugging, testing, and extending the code difficult.

The IQueryable Where takes an Expression<Func<TSource, bool>>, NOT a Func<TSource, bool>, so a different overload of Where is being called, causing the query to execute and the result to be returned as an IEnumerable instead of an IQueryable.

public static IQueryable<TSource> Where<TSource>( this IQueryable<TSource> source, Expression<Func<TSource, bool>> predicate )

Pass your Func as an Expression and you should get the desired behavior.

7d1bad12 is a Hex string and not your normal string. I assume you gave a delete request and shortly you logged into the system and saw your VPC still existing. VPC deletion is a time consuming process and it takes time before your VPC is deleted. When the API says it returned successfully it means that the SDK was able to send the delete request successfully and this delete request is asynchronous and therefore, it returns immediately. If your VPC was empty then after some time it should go away from the AWS console.

22259286 0 C++: Using a Stack to Verify if Parentheses are Balanced (Logic error)

I have a simple stack I created with basic initialize, show, push, pop, top, etc. functions. I need a function to verify whether or not a string has matching parentheses. I think I'm pretty close, but I have a problem with the following: if (s.size == 0 && c == ')') in the middle of my balanced function.

The image you've shown is probably a UISegmentedControl. That's how you tap something so that it stays selected (and other choices are deselected). It's easy to customize a segmented control so that the background image is different when a segment is selected vs. when it is not.

38023773 0 Assigning more than one video file to an id in rails

Am working on a video application where the app in rails receive video files from different user. The videos are sent individually not multiple upload. Am trying to make a user to me able to store more than one video in the same row. for example. if a user has uploaded a video before( say video1), if the same user( with same id) upload another video, i want to update the existing video field( video1, video2 or something similar). I don't want to create another row for the same user. In summary i want to link a user to more than one video submission without adding a new row. Am currently using carrierwave gem, how can i achieve this

class Submission < ActiveRecord::Base mount_uploader :videos, VideoUploader end

video field above

submit = Submission.find(8) #asumming 8 is the id of the same user submit.videos = params[:videos] #new parameter coming in

was also thinking of concantenating both the old valid and new valid seperated by a comma, but don't know how to handle that when calling the field.

You have several options, and it really depends on what you are trying to get the system to do.

fork child processes, and interface using connections their stdin/stdout pipes.
create a named pipe on the file system, like /tmp/mysql.sock. This is basically using sockets to communicate cross process.
Setup a message broker. I'd recommend giving ActiveMQ a try, and using the Stomp client for Perl. This is probably your most scalable solution.

Well, looks like it just enough to move you Cache logic to the ChannelInterceptor:

<int:channel id="tcpInbound"> <int:interceptors> <bean class="com.my.proj.si.CachePutChannelInterceptor" </int:interceptors> </int:channel>

And use this interceptor from any place when you need to use Cache.

40314237 0 Progress Bar with Ajax JQuery and PHP for import a .csv file to MySQL

I tried to write a code for a progress bar using PHP, JQuery and HTML. So, I made a Ajax Request for a PHP file and in the success Ajax parameter I search a data requested from PHP File like this..

success: function(data){ if(data == 'Error1'){ alert("The File is not a .csv"); }else if(data == "Error2"){ alert("Please select a file to import!"); }else{ $('#consumidor_table').html(data); alert("The importation has been made!"); } }

That else does print a Table with MySql DB lines. The PHP file read a .csv from a HTML input and insert those lines in DB.

Actually, my code to do a progress bar is it: Before at success parameter

xhr: function(){ var xhr = new window.XMLHttpRequest(); xhr.upload.addEventListener("progress", function(evt){ if (evt.lengthComputable) { var percentComplete = evt.loaded / evt.total; console.log(evt.loaded); console.log(evt.total); console.log(percentComplete*100); addProgress(percentComplete*100); } }); return xhr; },

The entire codes: JQuery; PHP URL

The Error: When a upload a file and submit the form, the console.log(evt.total); and console.log(evt.loaded); print the same value, and them the progress bar is fully, but the Ajax continues requesting the PHP file and my table is empty yet.

So what I can do to my progress bar work with the response from PHP file?

It sounds like you're not trying to do huffman coding yet, just turn "binary" Strings of 0 or 1 into Java integer types. Try this:

public static long decode(String textbytes) { long result=0; for(char ch : textbytes.toCharArray()) { result = result << 1; if(ch == '1') result = result + 1; } return result; }

This method decodes bit strings into Java longs. There's no need to worry about breaking into chunks of 8 (unless this is homework, and that's part of the assignment). In particular, it handles the example you gave properly ("11010001" => 209).

The approach is pretty simple:

Start with result = 0
For each character in the input string, shift result 1 bit to the left to "make room" for the bit represented by the current character. Afterwards, add 1 to result if the current character represents a 1 bit.

Also, the code assumes you get no bit strings longer than 64 bits, which you may want to check for robustness.

This isn't an answer but it is too long for a comment: sorry.

There are three possibilities for creating variable bindings that seem to be common:

variables are explicitly bound at the start of a scope;
there is a construct which creates a binding which can occur anywhere in a scope, but it's not just assignment;
variables get implicitly bound in a surrounding scope on their first assignment.

An example of (3) is Python. Languages which do this end up needing explicit scope-resolution operators (global and now nonlocal in Python) to deal with the stupid, lazy, pun they have done and are not worth discussing further: you need binding constructs which are distinct from assignment or you end up living in pain for ever.

Common Lisp is an example of (1), and C used to be: they are both (C was) examples of languages where all the bindings needed to be created at the start of a scope construct.

Within (1) there are languages which have some kind of block construct ({ ... } in C) which can be used for grouping and for scope, and ones which have a grouping construct and one or more separate scoping constructs: CL is in the latter family.

So in (old) C you would say

{ int i = 3; ... }

While in CL you say

(let ((i 3)) ...)

-- the scope construct here is let (and there are others of course).

Of course, CL, being a Lisp, can perfectly happily invent a construct which looks like C's blocks:

(defmacro scope (&body vars/body) (loop for (var? . body?) on vars/body while (and (listp var?) (<= 2 (length var?) 3) (eql (first var?) 'var) (symbolp (second var?))) collect (case (length var?) (2 (second var?)) (3 (rest var?))) into bindings finally (return `(let* ,bindings ,var? ,@body?))))

And now

(scope (var a) (var b 2) ...)

is a construct in the language.

So really these two variants on (1) are more similar than they are different: it's just a matter of how you cut up the underlying constructs you want in the language: C conflated scope blocks and grouping, CL doesn't.

(2) is different however. Here you are allowed to intermingle binding constructs and other things within a scope construct. C is now like this, and so is JavaScript. CL is not like this natively (obviously, being a Lisp, it could become like this with some macrology, although that macrology would be a lot hairier than what I wrote above).

In such a language you really need a separate binding-creation construct, because it can't be part of the scoping construct. Languages like C already treat the binding-creation construct as separate, so for them it's just a matter of relaxing the rule which says bindings must all be created at the start of a scope construct.

Languages like this have a significant question to answer though: what is the scope of a binding? Does something like

{ ... int x = 3; ... }

Really mean

{ ... { int x = 3; ... } }

or does it mean

{ int x; ... x = 3; ... }

The latter case is easier, but means that there's an awkward region where references to x are legal but its value may not be well-defined. C takes the former interpretation I think.

This is mostly fine for languages like C where the grouping construct is the same as the scoping construct. But it's not fine for languages like JavaScript where the grouping construct is not the scoping construct and, worse, where there is no scoping construct other than functions (or used not to be). And in fact languages like that can't really fix the problem, since there's no useful scoping construct. Well, of course, they fix it by growing a scoping construct.

Note that although CL is a (1) language there are Lisp-family languages which are (2) languages: in particular Racket is. In Racket (but not, I think, in Scheme) you can say

(define (foo) (define bar 1) ;; is baz bound here? (display bar) (define baz 3) (list bar baz))

And the answer is that yes, baz is bound there, but it's bound to an undefined object and you'll get an error (at run time, not compile time) if you try to use it. So this is a run-time error:

(define (foo) (define bar 1) (display baz) (define baz 3) (list bar baz))

while this

(define (foo) (define bar 1) (display baz) (let () (define baz 3) (list bar baz)))

is a compile time error. (I am actually slightly confused about which constructs in Racket create scopes.)

Generally speaking, yes.

You can get type of class with typeof(YourClassHere) or type of object with yourObject.GetType().

Then you can easily create object with an acitvator: Activator.CreateInstance(type, parameters for constructor)

EDIT AFTER QUESTION EDIT It's even easier when you have the generic.

public void DoWork<TClass>(int time) { IJobDetail job = (IJobDetail) Activator.CreateInstance(typeof(TClass), null /* no parameters */); job.WithIdentity("job1", "group1"); job.Build(); }

Modulus is not using the 3, it simply knows that:

 20 / 6 = 3, with a remainder of 2 => 20 % 6 = 2

If you want the 3, you just need the expression:

Math.floor(20 / 6)

(or possibly Math.trunc depending on how you want negative numbers handled - floor rounds towards negative infinity, trunc rounds toward zero).

It is actually possible to run multiple delayed_job workers.

From http://github.com/collectiveidea/delayed_job:

# Runs two workers in separate processes. $ RAILS_ENV=production script/delayed_job -n 2 start $ RAILS_ENV=production script/delayed_job stop

So, in theory, you could just execute:

$ RAILS_ENV=production script/delayed_job -n 50 start

This will spawn 50 processes, however I'm not sure whether that would be recommended depending on the resources of the system you're running this on.

An alternative option would be to use threads. Simply spawn a new thread for each of your jobs.

One thing to bear is mind with this method is that ActiveRecord is not thread-safe. You can make it thread-safe using the following setting:

ActiveRecord::Base.allow_concurrency = true

22440303 0 Webbrowser control in C# weird behavior

I'm finishing (QA testing) a web parser built in C# that is parsing specific data from a web site that is being load to a webbrowser control in a WFA (Windows Form Application) program.

The weird behavior is when I'm killing the internet connection... Actually the program is designed to navigate recursively in the site and each step its waiting for a WebBrowserDocumentCompletedEventHandler to be triggered. Beside that there is a Form timer set, and if the handler is not triggered in a specific interval then its reloading the entire procedure.

Everything is working good even if I manually avoid the handler from triggering - As I said the timer kicks in and restart the operation successfully and retrying another value successfully.

When shutting the internet connection manually while the procedure is running, I can see the page is getting the internet explorer message: "This page can't be displayed" (For some reason the DocumentComplete... is not triggered). Then immediately reconnecting the internet and waiting for the timer to kick in - As expected it fires the reload function but this time everything is going wild!! the functions are being fired not in the correct order and it seems like there is 100 threads that are running at the same time - a total chaos.

I know that its not easy to answer this question without experiencing that and seeing the code But if I copy the entire code it will be just too long using 5 different classes and I really can't see where is the problem... I'll try to simplify the question:

why when connection lost the documentcomplete handler don't fires?
Does anyone has experienced an application going wild only after webbrowser control losses connection?

Thanks

I understand why this error occurs. But the articles on SO does not have any valid solution for my case. Is it achievable with Cast, or any other way? Note: I do not want to convert to IEnumerable, I want to keep IQueryable.

It is possible to inherit from stream.Stream and make it work, however based on what's available in the documentation I would suggest inheriting from stream.Writable. Piping into a stream.Writable you'll need to have _write(chunk, encoding, done) defined to handle the piping. Here is an example:

var asset = new ProjectAsset('myFile', __dirname + '/image.jpg') var stream = fs.createReadStream(__dirname + '/image.jpg', { encoding: 'base64' }).pipe(asset) stream.on('finish', function() { console.log(asset.binaryData); })

Project Asset

'use strict' var stream = require('stream'), util = require('util') var ProjectAsset = function() { var self = this self.data self.binaryData = []; stream.Writable.call(self) self._write = function(chunk, encoding, done) { // Can handle this data however you want self.binaryData.push(chunk.toString()) // Call after processing data done() } self.on('finish', function() { self.data = Buffer.concat(self.binaryData) }) return self } util.inherits(ProjectAsset, stream.Writable) module.exports = ProjectAsset module.exports.DEFAULT_FILE_NAME = 'file'

If you're looking to also read from the stream, take a look at inheriting from stream.Duplex and also including the _read(size) method.

There's also the simplified constructors api if you're doing something simpler.

39667826 0 Setting a cookie in Django Rest Framework API

I am trying to set a cookie on my website when a GET request is made to an API end-point.

In my urls.py, I have this:

url(r'^api/cookies/$', views.cookies, name='cookies'),

which points to this view:

@api_view(['GET']) def cookies(request): if request.method == 'GET': response = HttpResponse('Setting a cookie') response.set_cookie('cookie', 'MY COOKIE VALUE') if 'cookie' in request.COOKIES: value = request.COOKIES['cookie'] return Response('WORKS') else: return Response('DOES NOT WORK')

In other words, when this view is loaded through a GET method, I am setting a cookie. If the cookie is set properly, I return 'WORKS', otherwise, I return 'DOES NOT WORK'.

Now, I am sending a GET request to this URL, and I get 'DOES NOT WORK', which means the cookie is not set properly. What am I doing wrong? How can I fix this? Note: I am using Django Rest Framework for my views.

You can use so-called keyword-messages. You end a method with a colon and put the variable name after that (probably multiple times).

So if you have something like methodFoo(a, b, c) in a curly-brace language, in Smalltalk you typically write

methodFoo: a withSomething: b containing: c

or likewise. This can make method names more readable, too!

Also, getters and setter in Smalltalk typically are named after the variable they are representing. (And classes are typically capitalized while variables are not)

So your example would turn into

The logic of your recursive function is just wrong. You never actually read the contents of the array. I'm surprised you got any meaningful output out of that.

You need to rethink of the recursive definition to perform this addition.

Base case(s):
Sum of an empty array is 0..
i.e., sum_of_array(x, 0) == 0.

Sum of a 1-element array is the value of the element.
i.e., sum_of_array(x, 1) == x[0]

Recursive case:
Sum of an n-element array is the sum of the nth element and the sum of the first n-1 elements.
i.e., sum_of_array(x, n) == x[n-1] + sum_of_array(x, n-1)

Figure out how to encode this logic in your function.

Update part of your code like this:

public int Min(int[] numbers) { int m = numbers[0]; for (int i = 0; i < numbers.Length; i++) { if (m > numbers[i]) { m = numbers[i]; } } return m; } public int Max(int[] numbers) { int m = numbers[0]; for (int i = 0; i < numbers.Length; i++) { if (m < numbers[i]) { m = numbers[i]; } } return m; }

EDIT: This will help you get rid of the error you are getting. But you still need to figure out the logic on returning the correct value.

The reason you were getting this error is because, if in case none of the numbers in the array int[] numbers that you are passing to the methods satisfy the if condition if (m > numbers[i]), the code would never reach the return statement.

8923174 0 OpenGL VAO best practices

Im facing an issue which I believe to be VAO-dependant, but Im not sure..

I am not sure about the correct usage of a VAO, what I used to do during GL initialization was a simple

glGenVertexArrays(1,&vao)

followed by a

glBindVertexArray(vao)

and later, in my drawing pipeline, I just called glBindBuffer(), glVertexAttribPointer(), glEnableVertexAttribArray() and so on.. without caring about the initally bound VAO

is this a correct practice?

I've never done this myself, so I kind of wanted to try it.

Everything we need:

2 Forms, 1 query, and 1 (technically 3) line(s) of VBA.

The "search"/parent form. I created a blank form and called it Form4. I added 2 textboxes, 2 labels, and a button to it.

txtSearch1 - Textbox 1
txtSearch2 - Textbox 2

I then created a query that filters records by what's in these 2 textboxes. I don't have the same table/schema you did, so bare with me on the names/data types.

My setup:

Table: tblEmployee
Fields: ID, EmployeeNumber, Names
Fields I am filtering: ID, EmployeeNumber

The Query: (mainly to show how we are filtering)

SELECT tbl_Employee.ID, tbl_Employee.EmployeeNumber, tbl_Employee.FirstName, tbl_Employee.LastName FROM tbl_Employee WHERE (((tbl_Employee.ID) Like "*" & [Forms]![Form4]![txtSearch2] & "*") AND ((tbl_Employee.EmployeeNumber) Like "*" & [Forms]![Form4]![txtSearch1] & "*"));

The searches are flexible, as they use wildcards. You can remove these, but I figured the more information the better.

So, we now have a Form with 2 textboxes that we use to narrow down our query results.

Next step, create another form to be inserted into Form4 to view our search results.

Create a blank Form (I named mine Form5, hooray). Right click in the top left corner of the Form, and select "Properties".

On the Format tab: Default View: Datasheet

On the Data tab: Record Source: Query5 (or your query name) Recordset Type: Dynaset

Go back to the form. In design view, in the Access Tool bar at the top, and to the right "Add Existing fields". Add whichever fields you want from your query.

Close Form5.

Open Form4 in Design View. Drag Form5 onto Form4. Save it.

On Form4, right click on the Button we added, or add it if you have not. Go to Properties, Event -> OnClick -> (click the three little ...). Double click on Code Builder. Type in Me.Form5.Requery. (or Me.YourFormNameHere.Requery).

Run Form4 and test your filtering capabilities.

First thing to remember is CI does not add $_FILES to the input object. You will need to access those like $_FILES['img1'] etc. So these:

'img1'=>$this->input->post('img1'),//image path is not inserting But all other fields are inserting into db 'img2'=>$this->input->post('img2'),//image path is not inserting

should be something like:

'img1'=>$_FILES['img1']['name'],//image path is not inserting But all other fields are inserting into db 'img2'=>$_FILES['img2']['name'],//image path is not inserting

depending on what you expect to be storing in the database. You can rename files, etc through the upload class. I would suggest reading over those docs.

Secondly, you don't appear to be calling the actual upload method:

$this->upload->do_upload()

Not sure if you needed this but... If you want multiple configs, you have to redefine the config for multiple files if you want them to have different paths...

$config['upload_path'] = 'uploads/'; $config['allowed_types'] = 'gif|jpg|jpeg|png'; $config['max_size'] = '1000'; $config['max_width'] = '1920'; $config['max_height'] = '1280'; $this->load->library('upload', $config); $this->upload->do_upload("img1"); $config['upload_path'] = 'some_other_dir/'; $config['allowed_types'] = 'gif|jpg|jpeg|png'; $config['max_size'] = '1000'; $config['max_width'] = '1920'; $config['max_height'] = '1280'; $this->upload->initialize($config); $this->upload->do_upload("img2");

and if you don't want them to have different paths, you can just load in the library as you do in your example and call do_upload() with no params passed.

If i missed the point or you need more info let me know and I may update.

normally you would use a CMS-alike workflow, where you can set up a Master Layout and then make an Administrative way to add content to each part of the page you would want.

In a simple way, you can just easily create pages using 2 textboxes and a submit button:

<input type="text" id="txtFileName" /> <textarea id="txtContent" rows="80" cols="12"></textarea> <input type="submit" id="btnSave" value="Save File" />

and have your code to create a new text file with the passed contents like:

// create a writer and open the file using (TextWriter tw = new StreamWriter( txtFileName.Text, false, System.Text.Encoding.UTF8)) { // write the content tw.Write(txtContent.Text); // close the stream tw.Close(); }

You can show a list of all files and read them the same way, so you can edit them...

Now, in ASP.NET, this might not work properly as the server will need to compile again and for that you will need to also change the project file, but you can run a local script issuing the compile line and that will re-compile everything for you.

Give it a try, and when you come up with some stopper, let us know, we might give you a hand on that...

9411544 0 parse date by prompting user for date format?

My application reads a csv file provided by the user. This csv file contains a field for date and / or time, formatted in any way the user chose it. Like: 1999/10/28 or 2000-01-01,3PM-02-59

I want to offer the user the possibility to indicate the formatting of the date and time in this field. So, I'd have an input window saying: "Specify the formatting of your date/time field" "Example: for 1999/10/28 format, input yyyy/mm/dd" "Other example: for 2000-01-01,3PM-02-59,input yyyy-dd-mm,hh-mm-ss"

I would retrieve their input as a string, then do some complicated and annoying operation to derive a regular expression from this string, which I would then apply in the csv parser to identify years, months, days, hours, etc. in the "date and time" field.

My question before embarking in this: is there a library which already does this kind of thing? Am I reinventing the wheel? Is there a much more obvious approach I'm missing?

Thanks a lot!

PS: yes, it is all about users providing their own strange date and time formats. No need to suggest that it would be easier with a a uniform format! :-)

Ok, again I reply to my own question, but this time with a positive remark. I think what I was doing wrong had something to do with the hidden - for me - implications of the Document-based architecture of the default Document Application template.

I have tried with a different approach, creating an application from scratch NOT flagging "Document-based Application" and providing it with:

1 NSDocument subclass
2 NSWindowControllers subclasses
1 MainMenu.xib
2 window.xib

and I have forced instantiation of the NSWindowController subclasses in the MyDocument code.

I have also put the IBActions for the MenuItems in the MyDocument and I have bound the MyDocument Object to the MenuItems in the MainMenu.xib.

This time I was able to do whatever, hiding/showing windows starting with one hidden one not, enabling menu items automatically at will.

Here follows the code, for any newbie like me who might have to fight with this in the future.

// MyDocument.h #import <Cocoa/Cocoa.h> #import "testWindowController.h" #import "test2WindowController.h" @interface MyDocument : NSDocument { testWindowController *test; test2WindowController *test2; } - (IBAction)showWindow1:(id)pId; - (IBAction)showWindow2:(id)pId; - (IBAction)hideWindow1:(id)pId; - (IBAction)hideWindow2:(id)pId; @end // MyDocument.m #import "MyDocument.h" #import "testWindowController.h" #import "test2WindowController.h" @implementation MyDocument - (id)init { self = [super init]; if (self) { // Initialization code here. NSLog(@"MyDocument init..."); [self makeWindowControllers]; } return self; } - (void)dealloc { [super dealloc]; } - (void)makeWindowControllers { test = [[testWindowController alloc] init]; test2 = [[test2WindowController alloc] init]; [self addWindowController:test]; [self addWindowController:test2]; // start hiding the first window [[test window] orderOut:self]; } - (IBAction)hideWindow1:(id)pId { NSLog(@"hideWindow1"); [[test window] orderOut:self]; } - (IBAction)showWindow1:(id)pId { NSLog(@"showWindow1"); [test showWindow:self]; [[test window] makeKeyAndOrderFront:nil]; // to show it } - (IBAction)hideWindow2:(id)pId { NSLog(@"hideWindow2"); [[test2 window] orderOut:self]; } - (IBAction)showWindow2:(id)pId { NSLog(@"showWindow2"); [test2 showWindow:self]; [[test2 window] makeKeyAndOrderFront:nil]; // to show it } -(BOOL)validateMenuItem:(NSMenuItem *)menuItem { NSLog(@"in validateMenuItem for item: %@", [menuItem title]); if ([[menuItem title] isEqualToString:@"Show Window"] && [[test window] isVisible]){ return NO; } if ([[menuItem title] isEqualToString:@"Hide Window"] && ![[test window] isVisible]){ return NO; } if ([[menuItem title] isEqualToString:@"Show Window2"] && [[test2 window] isVisible]){ return NO; } if ([[menuItem title] isEqualToString:@"Hide Window2"] && ![[test2 window] isVisible]){ return NO; } return [super validateMenuItem:menuItem]; }

13104157 0 How to display echo if user has not selected from a drop down menu

In my code below I have 2 drop down menus. One is a "Course" drop down menu and the other is a "Modules" drop down menu:

Below is the code:

 <?php // connect to the database include('connect.php'); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); die(); } $sql = "SELECT CourseId, CourseName FROM Course ORDER BY CourseId"; $sqlstmt=$mysqli->prepare($sql); $sqlstmt->execute(); $sqlstmt->bind_result($dbCourseId, $dbCourseName); $courses = array(); // easier if you don't use generic names for data $courseHTML = ""; $courseHTML .= '<select name="courses" id="coursesDrop" onchange="getModules();">'.PHP_EOL; $courseHTML .= '<option value="">Please Select</option>'.PHP_EOL; while($sqlstmt->fetch()) { $course = $dbCourseId; $coursename = $dbCourseName; $courseHTML .= "<option value='".$course."'>" . $course . " - " . $coursename . "</option>".PHP_EOL; } $courseHTML .= '</select>'; $moduleHTML = ""; $moduleHTML .= '<select name="modules" id="modulesDrop">'.PHP_EOL; $moduleHTML .= '<option value="">Please Select</option>'.PHP_EOL; $moduleHTML .= '</select>'; include('noscript.php'); ?> <script type="text/javascript"> function getModules() { var course = jQuery("#coursesDrop").val(); jQuery('#modulesDrop').empty(); jQuery('#modulesDrop').html('<option value="">Please Select</option>'); jQuery.ajax({ type: "post", url: "module.php", data: { course:course }, success: function(response){ jQuery('#modulesDrop').append(response); } }); } </script> <h1>EDIT AN ASSESSMENT'S DATE/START TIME</h1> <form action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>" method="post"> <table> <tr> <th>Course: <?php echo $courseHTML; ?></th> <th>Module: <?php echo $moduleHTML; ?></th> </tr> </table> <p><input id="moduleSubmit" type="submit" value="Submit" name="moduleSubmit" /></p> </form> <?php if (isset($_POST['moduleSubmit'])) { $sessionquery = " SELECT SessionId, SessionDate, SessionTime, ModuleId, TeacherId FROM Session WHERE (ModuleId = ? AND TeacherId = ?) ORDER BY SessionDate, SessionTime "; $sessionqrystmt=$mysqli->prepare($sessionquery); // You only need to call bind_param once $sessionqrystmt->bind_param("si",$moduleId,$userid); // get result and assign variables (prefix with db) $sessionqrystmt->execute(); $sessionqrystmt->bind_result($dbSessionId,$dbSessionDate,$dbSessionTime, $dbModuleId, $dbTeacherId); $sessionqrystmt->store_result(); $sessionnum = $sessionqrystmt->num_rows(); if($sessionnum ==0){ echo "<p>Sorry, You have No Sessions under this Module</p>";

module.php where it displays "Module" drop down menu:

 <?php // connect to the database include('connect.php'); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); die(); } $course = isset($_POST['course']) ? $_POST['course'] : ''; $sql = " SELECT cm.CourseId, cm.ModuleId, c.CourseName, m.ModuleName FROM Course c INNER JOIN Course_Module cm ON c.CourseId = cm.CourseId JOIN Module m ON cm.ModuleId = m.ModuleId WHERE (c.CourseId = ?) ORDER BY c.CourseId, m.ModuleId "; $sqlstmt=$mysqli->prepare($sql); $sqlstmt->bind_param("s",$course); $sqlstmt->execute(); $sqlstmt->bind_result($dbCourseId,$dbModuleId,$dbCourseName,$dbModuleName); $moduleHTML = ""; while($sqlstmt->fetch()) { $moduleHTML .= "<option value='$dbModuleId'>" . $dbModuleId . " - " . $dbModuleName . "</option>".PHP_EOL; } echo $moduleHTML; $sqlstmt->execute(); ?>

Now if you look at the bottom of the code, what happens is that it performs a query after the user has submitted the "Course" and "Module" drop down menus. if it doesn't find a session related with that module then it echos "Sorry, You have No Sessions under this Module".

But what my question is that I do not want this echo to be displayed if the user has not selected a "Course" and "Module" from their drop down menus or if the user has selected a course from the "Course" drop down menu but has not selected a module from the "Module" drop down menu.

Below is the echo's I wanted for each situation:

If user has not selected a course and a module: echo "Please Select a Course and Module";
If user has selected a course but not a module: echo "Please Select a Module";
If user has selected a course and module but no sessions appear: echo "Sorry, You have No Sessions under this Module";

List 3 from above at the moment works but how can I get list 1 and 2 to work by only displaying their echo's and no other echo?

UPDATE:

Javascript code where it validates drop down menus:

 function validation() { var isDataValid = true; var moduleTextO = document.getElementById("coursesDrop"); var courseTextO = document.getElementById("modulesDrop"); var errModuleMsgO = document.getElementById("moduleAlert"); if (courseTextO.value == "" && moduleTextO.value == ""){ errModuleMsgO.innerHTML = "Please Select a Course and Module"; isDataValid = false; } else if (courseTextO.value == ""){ errModuleMsgO.innerHTML = "Please Select a Course"; isDataValid = false; }else if (moduleTextO.value == ""){ errModuleMsgO.innerHTML = "Please Select a Module"; isDataValid = false; }else{ errModuleMsgO.innerHTML = ""; } return isDataValid; }

Below is HTML code:

<form action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>" method="post"> <table> <tr> <th>Course: <?php echo $courseHTML; ?></th> <th>Module: <?php echo $moduleHTML; ?></th> </tr> </table> <p><input id="moduleSubmit" type="submit" value="Submit" name="moduleSubmit" /></p> <div id="moduleAlert"></div> </form>

You can use Enumerable.Except to get distinct items from lines3 which is not in lines2:

lines2.AddRange(lines3.Except(lines2));

If lines2 contains all items from lines3 then nothing will be added. BTW internally Except uses Set<string> to get distinct items from second sequence and to verify those items present in first sequence. So, it's pretty fast.

openssl smime -sign -in file.xml -out file.b64 -passin pass:test -binary -nodetach -inkey cert.priv.pem -signer cert.pub.pem

By calling the functions "CryptMsgOpenToEncode" and "CryptMsgUpdate", I obtain a first signed file. Now I would add optional OID and others datas (more precisely the "SMIMECapabilities", and signing time).

First things first: Why are you trying to run a graphical application with superuser privileges? This is in general a a bad idea.

X11 implements various authentication mechanisms to prevent users which are not part of the login session to access the X server. This is implemented not though Unix file permissions, but through protocol authentication. So even if you're root, you can not talk to the X server, without jumping through a few hoops. In particular every client needs access to the Xauthority cookies. Those are stored by default in ${HOME}/.Xauthority but can be defined to be fetched from a different location using the XAUTHORITYenvironment variable.

So to pass that through sudo you'd set XAUTHORITY to point to your login session user's ~/.Xauthority and then call sudo with environment preserving option.

export XAUTHORITY="${HOME}/.Xauthority" sudo -E ./idea.sh

Or you could set the XAUTHORITY environment after sudo. Another, much more blunt options is to simply punch a hole into authentication that allows all clients running locally to access the X server. However this is a bad idea, because then every user on your system could run a keylogger or otherwise mess with your session (for example preventing the screen locker to work). You can punch that hole with xhost +si:localuser but you really should not do it.

This is my service start code and my class. it is long but problem is just with database and entityFrameWork section please omit other lines. consider I just want to read a data from database:

my service start code:

protected override void OnStart(string[] args) { System.Threading.Thread newThread = new System.Threading.Thread(new System.Threading.ThreadStart(ReadPolling.Read)); newThread.Start(); }

this is my ReadPolling.cs file:

public class ReadPolling { public static webtccUsersEntities db; public static void Read() { try { byte[] readBuffer = new byte[1024]; while (true) { writeToDb(readBuffer); System.IO.File.WriteAllText("D:\\1.txt", "read-write"); } } catch (Exception ex) { System.IO.File.WriteAllText("D:\\1.txt", ex.Message); } } public static void writeToDb(byte[] userId) { db = new webtccUsersEntities(); string _userId="";foreach(byte item in userId) { if(item!=0 || item!=40) _userId += (39 - item).ToString(); } _userId = "0009544023"; Time time; if(db.Times.Where(i=>i.userId==_userId).Count()>0)//User has at least one time { time = db.Times.Where(i => i.userId == _userId).OrderBy(i => i.dayDate).OrderBy(i=>i.inTime).Last();//last time if (time.dayDate == DateTime.Today)//today time { if(time.outTime==null)//wants an out for today { time.outTime = DateTime.Now.ToLocalTime();//an out for today db.SaveChanges(); } else//wants a new in/out for today { Time newTime = new Time();newTime = db.Times.Create(); newTime.userId = _userId; newTime.dayDate = DateTime.Now.Date; newTime.inTime = DateTime.Now.ToLocalTime(); db.Times.Add(newTime);db.SaveChanges(); } } else//not today time { //new in for today Time newTime = new Time();newTime = db.Times.Create();newTime.dayDate = DateTime.Today;newTime.inTime = DateTime.Now.ToLocalTime();newTime.userId = _userId; db.Times.Add(newTime);db.SaveChanges(); } } else//user first time { Time firstTime = new Time(); firstTime = db.Times.Create(); firstTime.userId = _userId;firstTime.dayDate = DateTime.Now.Date;firstTime.inTime = DateTime.Now.ToLocalTime(); db.Times.Add(firstTime);db.SaveChanges(); } } }

as you can see if an error occurs I write it to a file named "1.txt" in my drive "D:\". so when I start the service i open my text file and see the error "The underlying provider failed on Open.Login failed for user 'NT AUTHORITY\LOCAL SERVICE'.". what causes the problem?

12180268 0 How can I gently "bust" UIWebview?

Recently, a few developers have started creating apps which do nothing more than point at state-owned content (free, public property) through UIWebViews. This wouldn't ordinarily be a problem, except the apps are all ad-supported and some are even paid. Essentially, they're making money on state-owned content.

My question is this: how can I force the site to open a new Safari window rather than display in the UIWebview (which is wrapped in their app's branding)? I am able to detect UIWebview using the following, but am unable to do anything besides simply hide the content. I'd prefer it to provide a link to our content which then opens in Safari.

This is how I'm detecting UIWebview:

var is_uiwebview = /(iPhone|iPod|iPad).*AppleWebKit(?!.*Safari)/i.test(navigator.userAgent);

I tend to put them in a client context static class. This way they are easily accessible from anywhere in your application and you can initialize them (where needed) on application startup or user login.

There are several issues:

when you use with, you need to reference the object with .
the result of Offset(x,y) is a range, not a number - you are interested in the row, so you need to add .Row
the End(xlUp) thingy has to start from the last row to work

This is probably what you meant:

Sub ONJL() Dim lastrow As Long Dim wsRD As Worksheet 'Raw Data Set wsRD = Sheets("Raw Data") With wsRD Application.ScreenUpdating = False lastrow = .Range("J" & .Rows.Count).End(xlUp).Row .Range("J" & lastrow + 1).Formula = "=Today()" End With End Sub

And don't forget to turn the screenupdating on somewhere.

17449086 0 Edit external CSS/SCSS with javascript

I need to 'edit' a file that's already saved on my server, example:

<link rel="stylesheet" href="css/plugin.scss">

But not only that, I want to edit a certain specific line, in SASS you can define variables in css, basically, I'd like to search inside this file with JAVASCRIPT for the string:

'$increment:

And if it's found, find out what line it is on and replace that whole line with:

'$increment:10;

Basically I want to generate a downloadable file for the user that's custom depending on what settings they choose via a html input field.

If there's a simpler/better explanation I'm all ears :)

Sometimes you need to modify some fields before returning from the clone() method.

Check this : http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/Object.html#clone(). I pasted the relevant part here for convenience:

"By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified."

you need to declare inbuffer at least as many bytes as the size of MAX_PACKET char * inbuffer = new char[MAX_PACKET];

and place before each recv() memset(inbuffer,0,MAX_BUFFER); to zero out the buffer so you don't mistakenly see the tail end of a previous packet in the scenario you received two packets where the 2nd is shorter than the 1st.

if your incoming packet has no unique termination byte ie '\r' you need to add int recvbytes ; recvbytes =new recv(...) since recv returns the number of bytes received on the wire

Also you can not use getView() inside onCreateView because the view you are accessing has not been created yet. So you should do it like this:

View view = inflater.inflate(R.layout.dpsfrag, container, false);

TextView tv= (TextView) view.findViewById(R.id.textView1);

tv.setText("hello");

return view;

Both .each() and .map() are functions that are able to access the elements in your data.list. Read more about .each() and .map()

You can use one or the other, you don't need both:

$.map(data.list, function(val, i) { $('#category').append(new Option(val,val)); console.log("val1 " + val); });

$(data.list).each(function(i, val) { $('#category').append(new Option(val,val)); console.log("val1 " + val); });

Pay attention to the arguments order, .each() is in different order from .map().

A likely reason is that each “copyData” is actually referencing the data in the original. As such, the new data objects will keep a reference to the original object. This is generally an efficiency advantage, since no copy of the actual data needs to be made. (The exception would be if you planned to keep a small subrange around.)

All of the data objects will be released properly when the active NSAutoreleasePool is popped.

In general, you shouldn’t be looking at the retain count of objects anyway. Code that isn’t under your direct control can do just about whatever it wants with object references, as long as it balances its retains and releases properly. If you’re concerned about leaks, use appropriate tools such as Instruments’s Leaks instrument.

37502821 0 How do I pass parameters into a jQuery.click() function on a tag?

I have used the jQuery.click() function in the past with buttons and have had nothing but success, but I tried to use it to click on a <span> and it doesn't work.

Also I noticed that it automatically executed my function without listening to the click.

Judging how I used it on buttons, this would be the syntax:

<p><span id="example">Click Here</span></p> $("#example").click(exampleFunction(p1, p2));

But it does not seem to work. Again it just executes it without the click even taking place. I even tried:

$(document).on("click", "#example", exampleFunction(p1, p2));

Still no luck, same results.

Your select is not doing what you think it does.

The most compact version in PostgreSQL would be something like this:

with data(first_name, last_name, uid) as ( values ( 'John', 'Doe', '3sldkjfksjd'), ( 'Jane', 'Doe', 'adslkejkdsjfds') ) insert into users (first_name, last_name, uid) select d.first_name, d.last_name, d.uid from data d where not exists (select 1 from users u2 where u2.uid = d.uid;

Which is pretty much equivalent to:

insert into users (first_name, last_name, uid) select d.first_name, d.last_name, d.uid from ( select 'John' as first_name, 'Doe' as last_name, '3sldkjfksjd' as uid union all select 'Jane', 'Doe', 'adslkejkdsjfds' ) as d where not exists (select 1 from users u2 where u2.uid = d.uid;

It looks as if you want to use Express and the express.compress middleware. That will figure out if a browser supports gzip and/or deflate, so you don't have to.

var express = require('express'); var app = express(); app.use(express.compress()); app.get('/', function(req, res) { res.send({ app_id: 'A3000990' }); }); app.listen(3000);

In the simple case where the number of tasks is limited, I would do only a single query to retrieve them, and then separate them as follows:

tasks = Task.all @draft_tasks = tasks.select { |x| x.status == 'Draft' } @approved_tasks = tasks.select { |x| x.status == 'Approved' } @closed_tasks = tasks.select { |x| x.status == 'Closed' }

Furthermore, depending on the bendability of your requirements, I would even render them in a single table with a clear visual marker what the state is (e.g. background-colour or icons). Then there would not even be a reason to separate the tasks beforehand (but I can imagine this would break your UI completely).

None of the above is valid once the number of tasks becomes larger, and you will need to apply pagination, and you need to display three different tables (one for each state).

In that case you will need to use the three separate queries as answered by @Ben.

Now UI-wise, I am not sure how you can paginate over three different sets of data at once. So instead I would use a single table showing all the states, and offer the option to filter on the status. In that case at least it is clear for the user what pagination will mean.

Just my two cents, hope this helps.

Completely new answer as of given details. You are working with VBA so you can call WorksheetFunctions like

Dim someVariable someVariable = WorksheetFunction.Quotient(Worksheets("Sheet1").Cells(1, "A").Value, Worksheets("Sheet1").Cells(1, "B").Value) Debug.Print someVariable

There is a quite good list of supported functions available on MSDN WorksheetFunction. Please choose your current Excel version on the linked page.

Furthermore I found another very important site concerning your problem that states that not all WorksheetFunctions are supported as Application. (see support.microsoft.com)

So I searched for workarounds and found a quite simple one on StackOverflow. But on the other hand - you really could make use of the VBA builtIn operator MOD

' created some variables, as I made some attempts on creating a good example Dim value1 value1 = Worksheets("Sheet1").Cells(1, "A").Value Dim value2 value2 = Worksheets("Sheet1").Cells(1, "B").Value someVariable = value1 Mod value2 Debug.Print someVariable ' of course you may use a single line statement too someVariable = Worksheets("Tabelle1").Cells(1, "A").Value Mod Worksheets("Tabelle1").Cells(1, "B").Value

I think there are some pretty good links to have a deeper look into.

There are no negative ASCII values. ASCII includes definitions for 128 characters. Their indexes are all positive (or zero!).

You're seeing this negative value because the character is from an Extended ASCII set and is too large to fit into the char literal. The value therefore overflows into the bit of your char (signed on your system, apparently) that defines negativeness.

The workaround is to write the value directly:

unsigned char a = 0xAE; // «

I've written it in hexadecimal notation for convention and because I think it looks prettier than 174. :)

the * is making ptr an integer pointer and pointing it the null address, the "zero-th" location in memory

There should be no difference in performance no matter which form you use.

but I wouldn't complain if someone used one of the other forms.

Which is the "correct" way of invoking the operator?

All are correct - syntactically as well as semantically.

38223601 1 How to join three tables with Django ORM?

My models are:

class Profiles(models.Model): first_name = models.CharField() last_name = models.CharField() email = models.CharField() class Meta: db_table = 'users' class Products(models.Model): title = models.CharField() content = models.CharField() price = models.BigIntegerField() user = models.ForeignKey(Profiles, related_name="product_owner") # user_id class Meta: db_table = 'products' class UserFollows(models.Model): profile = models.ForeignKey(Profiles, related_name='profile_following') # profile_id following = models.ForeignKey(Profiles, related_name='profile_is_following') # following_id class Meta: db_table = 'user_follows'

To get what I want, I would query it a raw sql query below:

SELECT * FROM products, users, user_follows WHERE products.user_id=users.id AND user_follows.following_id=products.user_id AND user_follows.profile_id=12345;

but I need to do it with Django ORM. I can join 'users' and 'products' tables with select_related but I have no idea how to join 'user_follows'. And I need to apply filter on a field of 'user_follows' table. Please help!

You need to bind to a ViewModel.Value somehow, and then use a (nested) binding to a format string.

When you have only one value:

<TextBlock Text="{Binding Path=DemoValue, StringFormat={StaticResource SomeKey}}" />

When you also have {1} etc then you need MultiBinding.

Edit:

When you really want to change languages in a live Form then the sensible way is probably to do all formatting in the ViewModel. I rarely use StringFormat or MultiBinding in MVVM anyway.

24883358 0 How to Add custom markers to a google directions map at the start only of multiple journeys

Firstly let me say I am not a Java or even web developer. I have pieced together this code via the web and am almost at the finish point - but cannot get over the line.

I am mapping journeys for a trucking firm, and want to use a custom marker at the start of each journey, with no marker at the end of the journey. The attached code does all I need for mapping the journey but I can't get the markers to render on the page. What am I missing?

39042083 0 Do I need do clean up after launching TPL tasks

I have Windows service that needs to monitor different things in the system (connect to some WCF services, send some data, etc.) every minute.

For that I chose to use Quartz.NET jobs which look as follows:

internal class MonitorLaunchJob : IJob { public void Execute(IJobExecutionContext context) { MonitorBase[] monitors = GetAllMonitors(); foreach (var monitor in monitors) var task = monitor.Launch(); } }

monitor.Launch is the method with the following signature:

public abstract Task Launch()

The overrides of this method may use long-running operations like await TcpClient.ConnectAsync() and stuff like that. Those methods track their activity by themselves using a lot of logging, so I don't need to keep track of the Task returned by monitor.Start(). I need to just fire and forget.

Now, my question is: what do I do with this task that Launch method returns? I can't think of a reason to store it anywhere since it's a fire-and-forget operation. But on the other hand, if a method returns an object, it is weird to just ignore it. Do I need to do any sort of clean-up when the task is completed? Will I face any performance issues if I just leave the task be and never track its state?

You have to create an NSMutableParagraphStyle in combination with an NSAttributedString in order to display text as justified. The important part is to set NSBaselineOffsetAttributedName to 0.0.

Here's an example how to put everything together:

let sampleText = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum." let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.alignment = NSTextAlignment.Justified let attributedString = NSAttributedString(string: sampleText, attributes: [ NSParagraphStyleAttributeName: paragraphStyle, NSBaselineOffsetAttributeName: NSNumber(float: 0) ]) let label = UILabel() label.attributedText = attributedString label.numberOfLines = 0 label.frame = CGRectMake(0, 0, 400, 400) let view = UIView() view.frame = CGRectMake(0, 0, 400, 400) view.addSubview(label)

I am assuming the following format:

word definitionkey : definitionvalue [definitionkey : definitionvalue …]

None of those elements may contain a space and they are always delimited by a single space.

The following code should work:

awk '{ for (i=2; i<=NF; i+=3) print $1, $i, $(i+1), $(i+2) }' file

Explanation (this is the same code but with comments and more spaces):

awk ' # match any line { # iterate over each "key : value" for (i=2; i<=NF; i+=3) print $1, $i, $(i+1), $(i+2) # prints each "word key : value" } ' file

awk has some tricks that you may not be familiar with. It works on a line-by-line basis. Each stanza has an optional conditional before it (awk 'NF >=4 {…}' would make sense here since we'll have an error given fewer than four fields). NF is the number of fields and a dollar sign ($) indicates we want the value of the given field, so $1 is the value of the first field, $NF is the value of the last field, and $(i+1) is the value of the third field (assuming i=2). print will default to using spaces between its arguments and adds a line break at the end (otherwise, we'd need printf "%s %s %s %s\n", $1, $i, $(i+1), $(i+2), which is a bit harder to read).

Here is a practical answer, courtesy of user Kirill Slatin. Practical use example at the bottom of the answer.

If, like me, you need to use that response object as a scope variable, here's the trick:

This will return "undefined" in the console, and like me, you probably won't be able to use that response data on your page:

$http.get(ArbitraryInput).then(function (response) {$scope.data = response;}); console.log($scope.data);

However, this should work:

 $http.get(ArbitraryInput) .then(function (response) { $scope.data = response; $scope.$apply() });

$scope.$apply() is what will persist the response object so you can use that data.

Why would you need to do this?

I'd been trying to create an "edit" page for my recipes app. I needed to populate my form with the selected recipe's data. After making my GET request, and passing the response data to the $scope.form, I got nothing... $scope.$apply() and Kirill Slatin helped big time. Cheers mate!

Here's the example from my editRecipeController:

 $http.get('api/recipe/' + currentRecipeId).then( function (data) { $scope.recipe = data.data; $scope.form = $scope.recipe; $scope.$apply() } );

Hope that helps!

10198230 0 Simple way to solve a system of linear equations in Matlab?

I'm looking for an easy and fast solution to the following problem: I have three 3D vectors x_i, three 3D vectors y_i, a 3D vector b and a 3x3 matrix A with coefficients a11 - a33 (that are unknown).

The relation is as follows:

x_i = A * y_i + b

That resolves to

x_i_1 = ( a11 * y_1_1 + a12 * y_2_1 + a13 * y_3_1 ) + b_1

etc.

So there are 9 equations and 9 unknown variables a11 - a33, easy peasy math. But how do I solve this system using build in Matlab functions?

RSA *r = PEM_read_RSAPrivateKey("C:/xampp/htdocs/RSA/daten.txt", NULL, NULL, NULL); resultDecrypt = RSA_private_decrypt( 128 /* resultEncrypt*/ , encrypted, decrypted, r, RSA_PKCS1_OAEP_PADDING); printf("%d from decrypt: '%s'\n", resultDecrypt, decrypted); RSA_free ( r );

Thanks!!

How do I call a private method in this type of parent class? What I have done is an ugly peice of code but it works though I don't think it's a real solution.

Would really appreciate some advice on how this is done. I have looked to find solution but non that have given me some clarity on the matter.

 public abstract class Car { public void passItOn(int a) { takesVariable(a); } private void takesVariable(int a) { //Process the variables }

the child:

 public abstract class Wheel extends Car { boolean a = anotherMethod(); if(value() != a) { passItOn(a); } }

There is some issue with my accaptance rate but I am on it! All will give + marks for replies!!!

You can do something like below, for starters:

16991135 1 Problems with character-encoding when webscraping with scrapy

I have problem with the encoding of the text, I am scraping from a website. Specifically the Danish letters æ, ø, and å are coming out wrong. I feel confident that the encoding of the webpage is UTF-8, since the browser is showing it correctly with this encoding.

I have tried using BeautifulSoup as many of the other posts have suggested, but it wasn't for the better. However, I probably did it wrong.

I am using python 2.7 on a windows 7 32 bit OS.

The code I have is this:

# -*- coding: UTF-8 -*- from scrapy.spider import BaseSpider from scrapy.selector import HtmlXPathSelector from scrapy.item import Item, Field class Sale(Item): Adresse = Field() Pris = Field() Salgsdato = Field() SalgsType = Field() KvmPris = Field() Rum = Field() Postnummer = Field() Boligtype = Field() Kvm = Field() Bygget = Field() class HouseSpider(BaseSpider): name = 'House' allowed_domains = ["http://boliga.dk/"] start_urls = ['http://www.boliga.dk/salg/resultater?so=1&type=Villa&type=Ejerlejlighed&type=R%%C3%%A6kkehus&kom=&amt=&fraPostnr=&tilPostnr=&iPostnr=&gade=&min=&max=&byggetMin=&byggetMax=&minRooms=&maxRooms=&minSize=&maxSize=&minsaledate=1992&maxsaledate=today&kode=&p=%d' %n for n in xrange(1, 3, 1)] def parse(self, response): hxs = HtmlXPathSelector(response) sites = hxs.select("id('searchresult')/tr") items = [] for site in sites: item = Sale() item['Adresse'] = site.select("td[1]/a[1]/text()").extract() item['Pris'] = site.select("td[2]/text()").extract() item['Salgsdato'] = site.select("td[3]/text()").extract() item['SalgsType'] = site.select("td[4]/text()").extract() item['KvmPris'] = site.select("td[5]/text()").extract() item['Rum'] = site.select("td[6]/text()").extract() item['Postnummer'] = site.select("td[7]/text()").extract() item['Boligtype'] = site.select("td[8]/text()").extract() item['Kvm'] = site.select("td[9]/text()").extract() item['Bygget'] = site.select("td[10]/text()").extract() items.append(item) return items

It is the items 'Adresse' and 'Salgstype' that contain æ, ø, and å. Any help is greatly appreciated!

You can compare the php bytecode with bytekit-cli (blogpost) / (github project).

To see if your new and old code produces the same php-bytecode. Knowing that you can be pretty sure everything will work. (If you are using annotations i'm not to sure how that works out with that)

as far as I can see you have a custom comparator (why does that keep a reference to the sorter? looks fishy) not a custom RowSorter.

The intended way to change sorting is to invoke toggleSortOrder(column) on RowSorter. For more fine-grained control you can need access to the DefaultRowSorter, f.i. its setSortKeys method.

Technically you can write recursive lambda expressions, but you need to be insane or insanely bright to try (I haven't figured out which). But you can cheat:

 Func<Node, decimal> nodeSum = null; nodeSum = node => { decimal result = node.Amount; if (node.Children != null) { result = result + node.Children.Sum(nodeSum); } return result; }; var value = nodeSum(amounts);

In order to submit POST data, the data must be sent to the server. A hyperlink alone cannot do this - however with a bit of JS magic, you can easily accomplish this.

If you're using something like jQuery, you can capture the click event - gather data from the link based on the click event, and submit to the server via $.post/$.ajax.

HTML:

<a href="javascript:void(0);" class="age-less-then-five">age<5</a>

Javascript:

$('a.classname').click(function(){ var that = $(this), value = that.text().trim(); //you can optionally store a value in the classname, or ID which is what I would do.. in this scenario.. I think XD $.post('yoururl.com/phpscript.php',{postName: value}, function(data){ //load whatever data you want, or redirect to list.html now that you've gathered desired data } });

To clarify the above answer, var that = $(this); refers to the link that's been clicked on. So you could grab the class name from the anchor by: that.attr('class') // which would equal age-less-then-five or simply do as above, and grab the text inbetween the anchor tags by using .text(). We trim here, this really isn't the best way to do this.. but it is one way to do it. When I'm using a link to perform any sort of post to the server, I'll typically use an ID if it holds a unique value, or class name.

10009022 0 How to add subView to another view from third view?

its pretty simple to understand the problem i have.

i have a view called "Menu" - which have few buttons. i have another view called "Main" - who need to show the view selected by the menu. and last one i have the view that i want to see in the main view.

i tried to work this out with this code -

-(IBAction)opertunity:(id)sender{ OpertunityViewController *temp = [[OpertunityViewController alloc]initWithNibName:@"OpertunityViewController" bundle:nil]; MainViewController *main = [[MainViewController alloc]init]; [main.handlerView addSubview:temp.view]; }

but it's not working at all.. i remember i done it many many times in the past but just cant get the answer in my projects... pretty strange /:

UPDATE - im trying something else. i made a method in my main class and i call it from the menu. but still it dosent work - and i NSLOG the method and its called perfectly. (when im calling the method from inside the class its working..)

what now ?! i've never had this kind of problem...

36766308 0 Wrap recursive files/dirs iteration with Promise

I need to check some directories tree for files and then create same directories structure on the server, and also create files list to upload to server. So I realise I need to wrap my dirs iterators with promise so I can get final file list on ".then()":

export function uploadHandler(filesAndDirs, currentDirectory) { return (dispatch, getState) => { filesToUpload = []; iterate(filesAndDirs, currentDirectory).then((whatResolved) => { console.log(whatResolved + ' is resolved'); // console.log(filesToUpload); }); } }

But I faced some trouble while resolving my promise, cause working with recursion I dont know exactly which file/dir is the last one:

function iterate(filesAndDirs, currentDirectory) { return new Promise(function(resolve) { for (let i = 0; i < filesAndDirs.length; i++) { if (typeof filesAndDirs[i].getFilesAndDirectories === 'function') { let dir = filesAndDirs[i]; createDirectory(dir.name, currentDirectory._id).then((directory) => { dir.getFilesAndDirectories().then((subFilesAndDirs) => { iterate(subFilesAndDirs, directory).then(() => { if (i + 1 == filesAndDirs.length) resolve('+++ by dir'); }); }); }); } else { filesToUpload.push({ file: filesAndDirs[i], directory: currentDirectory }); // If last item is file then I need to resolve the main promise // but same time if I will resolve promise here then // whole chain will break couse subdirectories handling async } }; }); }

I made it works for [dir] input but I cant handle it if [dir, file] input. What can I do here? Maybe its just bad idea to use Promise here?

24471126 0 How to track if location services is enabled or not enabled? titanium

I am able to turn it off.

code:

//get current Location // Titanium.Geolocation.accuracy = Titanium.Geolocation.ACCURACY_BEST; Titanium.Geolocation.distanceFilter = .25; var overlays = require('overlays'); //check if gps is enabled exports.checkGPS = function(windowCur) { Ti.Geolocation.accuracy = Titanium.Geolocation.ACCURACY_BEST; // make the API call var wrapperW = overlays.wrapperOverlay(windowCur); Ti.Geolocation.getCurrentPosition(function(e) { // do this stuff when you have a position, OR an error if (e.error) { Ti.API.error('geo - current position' + e.error); //put overlay on overlays.GPSError(windowCur); return; }else{ //alert(JSON.stringify(windowCur)); wrapperW.hide(); } }); };

This works fine at getting whether the user has turned on or off their location services. An overlay is put on the screen informing the user they need to turn it on, if they have turned it off.

However the problem is after the user has set it, and then goes into settings -> location services and enabled it, I am unable to take the overlay off as I have know way off tracking in real time if it has been turned on or off.

Does anyone know how this can be achieved, cheers.

UPDATE:

This did the trick

var wrapperW = null; Titanium.Geolocation.addEventListener('location', function(e) { if (e.error) { //put overlay on wrapperW = overlays.GPSError($.win); } else { //keep updating Ti.API.info(e.coords); if (wrapperW != null) { wrapperW.hide(); } } });

An easy option you can try is this method from the Bitmap class.

You can select the compression format of a bitmap and to optimise either the quality, or the file size. A downside is that the you need to get a Bitmap instance to start the compression, which may be something you don't want to do.

SELECT Plate_Number, MAX(kilometer) as max,MIN(kilometer) as min, (max - min) as result, sum(litters) as litters, date FROM log_table WHERE date BETWEEN 5 AND 9 GROUP BY Plate_Number

In case you always need max and min date, you can change it like

WHERE date BETWEEN (SELECT DISTINCT min(date) FROM log_table) AND (SELECT DISTINCT max(date) FROM log_table)

if (false !== ($url = filter_var($url, FILTER_VALIDATE_URL))) { echo "$url is a valid url"; }

You can optionally add these options as the third parameter (use binary or to combine them):

FILTER_FLAG_PATH_REQUIRED
FILTER_FLAG_QUERY_REQUIRED

I wrote a blog post on this awhile back. The first part is about when a thread can be aborted, the second is about how it actually works.

I hadn't ever seen any correct (in this case, complete) documentation about how it actually works, so I wrote about about it.

The jist is that the CLR will use SetThreadContext (a win32 api) to hijack your current IP and move you into a special stub to set up the thread abort if you're thread isn't in an abortable wait.

I'm not very aware of MySQL specific data modeling tools, but there's no infrastructure to add columns to every table ever created in a database. Making this an automatic behavior would get messy too, when you think about situations where someone added the columns but there were typos. Or what if you have tables that are allowed to go against business practice (the columns you listed would typically be worthless on code tables)...

Development environments are difficult to control, but the best means of controlling this is by delegating the responsibility & permissions to as few people as possible. IE: There may be 5 developers, but only one of them can apply scripts to TEST/PROD/etc so it's their responsibility to review the table scripts for correctness.

28421709 0 Why does the signature of deriveHCons declare `HK <: Symbol` when Symbol is a final class

Here is the signature of deriveHCons in LabelledProductTypeClassCompanion of Shapeless:

implicit def deriveHCons[HK <: Symbol, HV, TKV <: HList] (implicit ch: Lazy[C[HV]], key: Witness.Aux[HK], ct: Lazy[Wrap[TKV] { type V <: HList }] ): Wrap.Aux[FieldType[HK, HV] :: TKV, HV :: ct.value.V] = ...

It seems strange to me that we declare a type parameter HK that must derive from Symbol when Symbol is a final class. How can anything but Symbol replace the type parameter HK? If HK is always Symbol, this signature would be less imposing if it got rid of HK and substituted Symbol in the type signature directly would it not?

You can not to use prepare result without check.
It able to return false if any error occured.

if ($resolve = $data_base->prepare("INSERT INTO links VALUES('',?,?)")) { $resolve->bind_param("ss",$link, $short); // Problematic frame $resolve->execute(); } else { // You can get error message here printf("Error: %s.<br/>\n", $resolve->error); // assumed this is mysqli $resolve->close(); }

May be you get sql syntax error, about your insert query should be like this:

INSERT INTO links (long_url, title) VALUES (?, ?);

Solution:

What you are looking for is called Structural Search/Replace.

It is not very well documented but it is Extremely Powerful once you grok it completely.

There are a few examples in the Existing Templates that you can probably modify and learn from, the following will do what you are asking for now.

Here is how:

Go to the Menu: Edit -> Find -> Replace Structurally and use the following Search Template.

System.out.println($EXPRESSION$);

Check Case Sensitive and make File Type = Java Source

Set the Scope of the search to Project Files for everything.

If you want to just remove it all you can just make sure the Replace Template field is blank.

You could comment them all out with a Replace Template of //System.out.println($EXPRESSION$); or /* System.out.println($EXPRESSION$); */

Better Solution:

Use the Structural Search/Replace to add private static final Logger L = LoggingFactory($Class$.class); to all the classes with the System.out.println() statements.

Then replace all the System.out.println($EXPRESSION$); with L.info($EXPRESSION$);

You can even do things sophisticated things like the following:

This is just an example idea, the body of the catch needs to only have the the System.out.println($EXPRESSION$) a more sophisticated block to grab other expressions and keep them would be an exercise for the reader.

try { $TryStatement$; } catch($ExceptionType$ $ExceptionRef$) { System.out.println($EXPRESSION$); }

with

try { $TryStatement$; } catch($ExceptionType$ $ExceptionRef$) { L.error($EXPRESSION$); }

Best Solution:

Always use a Logger instead of System.out.println() in everything. Even in scratch classes used for experimenting, they eventually end up in production code at some point!

What the commenters have suggested is that all the javascript should be placed on external files. According to my understanding what you are doing is:

<script language="javascript"> your code here </script>

Instead you should have.

<script src="myjavascript.js" type="text/javascript"></script>

Then your javascript files will be automatically cached by the browser.

MindFold also goes on to suggest using google's CDN . which is a good suggestion. Of course you can only use it for popular libraris like Jquery.

You need to get the current <script> tag, which in this case is the last one:

var thisScript = document.scripts[document.scripts.length - 1];

and insert the <iframe> after it:

var parent = thisScript.parentElement; parent.insertBefore(iframe, thisScript.nextSibling);

http://jsfiddle.net/mattball/Tz75x/

Or simply replace the current script with the <iframe>:

var parent = thisScript.parentElement; parent.replaceChild(iframe, thisScript);

http://jsfiddle.net/mattball/a23XE/

Alternately – if you can believe it – document.write() is actually a suitable solution here, so long as you do it while the document is loading and not in a window.onload callback:

function createIframe() { document.write('<iframe src="//example.com"></iframe>'); } createIframe();

cherlietfl is right.

The problem is that you break the reference to the messages array since you assign a new array to messages inside your get function. But concat is doing this as well.

Try this:

Restangular.all('/api/messages/').getList({'_id': userId}).then(function(docs){ messages.splice(0, messages.length); // clear the array messages.push.apply(messages, docs); //add the new content });

2079615 0 Seeking good practice advice: multisite in Drupal

I'm using multisite to host my client sites.

During development stage, I use subdomain to host the staging site, e.g. client1.mydomain.com.
And here's how it look under the SITES folder:

/sites/client1.mydomain.com

When the site is completed and ready to go live, I created another folder for the actual domain, e.g. client1.com. Hence:

/sites/client1.com

Next, I created symlinks under client1.com for FILES and SETTINGS.PHP that points to the subdomain
i.e.

/sites/client1.com/settings.php --> /sites/client1.mydomain.com/settings.php /sites/client1.com/files --> /sites/client1.mydomain.com/files

Finally, to prevent Google from indexing both the subdomain and actual domain, I created the rule in .htaccess to rewrite client1.mydomain.com to client1.com, therefore, should anyone try to access the subdomain, he will be redirected to the actual domain.

This above arrangement works perfectly fine. But I somehow feel there is a better way to achieve the above in much simplified manner. Please feel free to share your views and all advice is much appreciated.

13861780 0 SVG: dynamic size based on text, merging objects

<div style="float: left; padding: 10px; border: 1px solid; background: #ccc">random text</div>

Is there a way to achieve something like this in SVG? I mean to have a rectangle and a text and:

a) rectangle's width and height are dynamic, so when I change the text, the rectangle adjust its size
b) when I move the rectangle, the text goes with it

And would it be easier to achieve something like this in <canvas>?

EDIT:

<defs> <text id="text1" x="90" y="100" style="text-anchor:start;font-size:30px;"> THIS IS MY HEADER</text> </defs> <filter x="0" y="0" width="1" height="1" id="background"> <feFlood flood-color="gray"/> <feComposite in="SourceGraphic"/> </filter> <use xlink:href="#text1" fill="black" filter="url(#background)"/>

Erik Dahlström proposed something like this. How to put padding to the background, how to add eg. shadow or border to the rectangle? And, this doesn't work in IE9, so I cannot accept it. I could just use <foreignObject> if there was a support for it in IE.

And I just figured out the answer for b) point of my question. You have to put both elements in the group:

<g> <rect x="0" y="0" width="100" height="100" fill="red"></rect> <text x="50" y="50" font-size="14" fill="blue" text-anchor="middle">Hello</text> </g>

And then you can move the group using transform param:

<g transform="translate(x, y)">

Seems to work correct in every browser.

The standard ListView has a property called checkboxes that can be set to true.
If you use that then you don't have to mess with making your own checkboxes.
I've never had any problems with checkboxes not showing properly in this control.

This property works best in ViewStyle:= vsList or ViewStyle:= vsReport

Alternatively if you want checkboxes on some items but not on others then make a picture of a checkbox (1 unchecked, 1 checked) and add both of them to an ImageList.
If an item needs a checkbox, set its ImageIndex property to that of the unchecked item. If it needs to be checked, set its ImageIndex property to the checked Image.
This works in ViewStyle:= vsReport and ViewStyle:= vsList.

You are using a custom ListView (TsListView) control, try using a standard ListView instead and see if the strange behaviour shows up.

This does not explain why your method stops so soon, but you need to take care of it or you will have an even stranger problem with the result data being completely garbled.

From the APi doc of DataInputStream.read():

Reads some number of bytes from the contained input stream and stores them into the buffer array b. The number of bytes actually read is returned as an integer.

You need to use that return value and call the write() method that takes and offset and length.

525803 0 How can I trust the behavior of C++ functions that declare const?

The output was 7!

So, how can we make sure of the behavior of C++ functions, if it was able to change a supposed-to-be-constant parameter!?

You could always create a service that returns a Stream and use the JsonSerializer to serialize your objects into a MemoryStream, and then return the MemoryStream from the service:

public Stream GetSomeObject(int groupId) { byte[] bytes; var serializer = new JavaScriptSerializer(); switch(groupId) { case 2: var groups = GetGroups(); // fill the groups however bytes = Encoding.UTF8.GetBytes(serializer.Serialize(groups)); break; case 3: var customers = GetCustomers(); bytes = Encoding.UTF8.GetBytes(serializer.Serialize(customers)); break; } return new MemoryStream(bytes); }

In that case, you would simply load the appropriate object into memory based on the parameters and return the appropriate strongly typed object via the Stream.

This is the same approach I've used in the past to return Json results from a WCF Service without the type information (the approach was suggested by a member Microsoft's WCF team, so I figured it was fairly reliable).

Grouping by Linn (town) and Nimi (name) tells the db engine to give you one row for each combination of town and name, and show you the maximum Vanus (age) for each of those combinations. And logically, that's not what you want. You want the name of each person whose age is the same as the maximum age in that town.

First verify you can retrieve the max age for each LinnID.

SELECT LinnID, Max(Vanus) As MaxOfVanus FROM Myyjad GROUP BY LinnID;

If that works, you can save it as "qryTownAge", then use it in another query where you join it (on LinnID) with Linnad. That will allow you to retrieve the matching Linn.

SELECT l.LinnID, l.Linn, q.MaxOfVanus FROM Linnad AS l INNER JOIN qryTownAge AS q ON l.LinnID = q.LinnID ORDER BY l.Linn;

If that works, save it as qryTownAge2. Then try this query.

SELECT q.Linn, q.MaxOfVanus, m.Nimi FROM qryTownAge2 AS q INNER JOIN Myyjad AS m ON ( m.LinnID = q.LinnID AND m.Vanus = q.MaxOfVanus ) ORDER BY q.Linn;

If that all works, you could create a single query which does it all. However, doing it step by step should help us pinpoint errors.

You can force this by avoiding the background image altogether as you replace it with a regular image in the <img> tag. Layer containers of content (one with the image and another with text) on top of each other with absolute position and z-index. It's a workaround to the background image problems I've experienced similar to yours and the layers provide nice flexibility for managing content.

#z1 { z-index: 1; } #z2 { z-index: 2; padding: 5%; color: white; } #z1, #z2 { position: absolute; left: 0px; top: 0px; }

<div id="outer"> <div id="z1"> <img width="100%" src="http://www.verolago.com/blog/wp-content/uploads/2013/11/sailboat.jpg" /> </div> <div id="z2"> <p>I'm on a boat!</p> </div> </div>

While it is not free (but $39), FireDaemon has worked so well for me I have to recommend it. It will run your batch file but has loads of additional and very useful functionality such as scheduling, service up monitoring, GUI or XML based install of services, dependencies, environmental variables and log management.

I started out using FireDaemon to launch JBoss application servers (run.bat) but shortly after realized that the richness of the FireDaemon configuration abilities allowed me to ditch the batch file and recreate the intent of its commands in the FireDaemon service definition.

There's also a SUPER FireDaemon called Trinity which you might want to look at if you have a large number of Windows servers on which to manage this service (or technically, any service).

FYI: I have to use data-label as a selector for other reasons..

I need to store values from a form to use later via js, so that when a user toggles a radio button the values will be re-inserted into the form inputs.

How do I store the values, then re-insert them when the user clicks a radio button? Here's where I am at:

// user clicks initially, then the values would be stored.. $('[data-label="FrenchCheckbox"] [data-label="State1"] [data-label="Checkbox"] [data-label="Unchecked"]').click(function() { // want to store the initial value now!! // ..then translating the form inputs to another lang $('[data-label="Create StepWizard"] [data-label="CreateAssetInput"]').each(function(i, ele) { var tString = $(ele).val(); if(tString.length <= 0) return; var tSrc = 'en'; var tDst = 'fr'; var key = 'my api key'; var tUrl = "https://www.googleapis.com/language/translate/v2?key=" + key + "&source=" + tSrc + "&target=" + tDst + "&q=" + tString; $.get(tUrl, function(response) { $(ele).val(response.data.translations[0].translatedText); }); }); });

Then when the user clicks the radio button (first line below) reinsert the initial values into the form fields?

$('[data-label="LanguageRadioButtons"] [data-label="French"] [data-label="Radio Button"] [data-label="Initial"] ').click(function() { // how do I reinsert the values from the initial input? });

Thanks for your ideas!

In Python 3.5, the async for syntax is introduced. However, asynchronous iterator function syntax is still absent (i.e. yield is prohibited in async functions). Here's a workaround:

import asyncio import inspect class escape(object): def __init__(self, value): self.value = value class _asynciter(object): def __init__(self, iterator): self.itr = iterator async def __aiter__(self): return self async def __anext__(self): try: yielded = next(self.itr) while inspect.isawaitable(yielded): try: result = await yielded except Exception as e: yielded = self.itr.throw(e) else: yielded = self.itr.send(result) else: if isinstance(yielded, escape): return yielded.value else: return yielded except StopIteration: raise StopAsyncIteration def asynciter(f): return lambda *arg, **kwarg: _asynciter(f(*arg, **kwarg))

Then your code could be written as:

@asynciter def countdown(n): while n > 0: yield from asyncio.sleep(1) #or: #yield asyncio.sleep(1) n = n - 1 yield n async def do_work(): async for n in countdown(5): print(n) asyncio.get_event_loop().run_until_complete(do_work())

To learn about the new syntax, and how this code works, see PEP 492

The accept attribute expects MIME types, not file masks. For example, to accept PNG images, you'd need accept="image/png". You may need to find out what MIME type the browser considers your file type to be, and use that accordingly. However, since a 'drp' file does not appear standard, you might have to accept a generic MIME type.

Additionally, it appears that most browsers may not honor this attribute.

The better way to filter file uploads is going to be on the server-side. This is inconvenient since the occasional user might waste time uploading a file only to learn they chose the wrong one, but at least you'll have some form of data integrity.

Alternatively you may choose to do a quick check with JavaScript before the form is submitted. Just check the extension of the file field's value to see if it is ".drp". This is probably going to be much more supported than the accept attribute.

21290403 0 WebSockets and HTTPS load balancers

I cannot find authoritative information about how WSS interacts with HTTPS proxies and load balancers.

I have a load balancer that handles the SSL (SSL off-loading), and two web servers that contains my web applications and handle the requests in plain HTTP. Therefore, the customers issue HTTPS requests, but my web servers get HTTP requests, since the load balancer takes care of the SSL certificates handling.

I am developing now an application that will expose WebSockets and SSL is required. But I have no clear idea about what will happen when the load balancer gets a secure HTTPS handshake for WSS.

Will it just relay the request as normal handshake to the web server? WebSockets use a "Upgrade:WebSocket" HTTP header that is only valid for the first hop (as there is also "Connection:Upgrade", will this be a problem?

Really use XML and not something that just sort of looks like XML and really parse it with something like lxml.etree.
Just store the number in a file if this is the entirety of your configuration. This solution isn't really easier than just using JSON or something, but it's better than the current one.

Implementing a bad solution now for future needs that you have no way of defining or accurately predicting is always a bad approach. You will be kept busy enough trying to write and maintain software now that there is no good reason to try to satisfy unknown future needs. I have never seen a case where "I'll put this in for later" has led to less headache later on, especially when I put it in by doing something completely wrong. YAGNI!

As to what's wrong with your snippet other than using an entirely wrong approach, angled brackets have a meaning in regex.

Since the only reason not to use Streams is that it can be tricky to ensure the JVM isn't keeping references to early conses around, one approach I've used that's fairly nice is to build up a Stream and immediately convert it to an Iterator for actual use. It loses a little of Stream's nice properties on the use side especially with respect to backtracking, but if you're only going to make one pass over the result it's frequently easier to build a structure this way than to contort into the hasNext/next() model of Iterator directly.

You can access object properties in two ways:

objectName.propertyName or objectName[propertyName]

so in your case:

addeles[b].innerHTML = "<img src='"+ jsonLoader["slider1"][b].coverlink +"'/>"

or to make it dynamic:

var string = "slider1"; addeles[b].innerHTML = "<img src='"+ jsonLoader[string][b].coverlink +"'/>"

To my knowledge, there is no such rule. The rule is to hit the database as least as possible, and rails gives you the right tools for that, using the joins.

The example Sam gives above is exemplary. Simple code, but behind the scenes rails has to do two queries, instead of only one using a join.

If there is one rule that comes to mind, that i think is related, is to avoid SQL where possible and use the rails way as much as possible. This keeps your code database agnostic (as rails handles the differences for you). But sometimes even that is unavoidable.

It comes down to good database design, creating the correct indexes (which you need to define manually in migrations), and sometimes big nested structures/joins are needed.

I'm trying to write a Java RegEx that will extract the domain name from a list of domains, sub-domains, and multi sub-domains.

There are too many domains to maintain with the RegEx I have written, and there is a lot more out there. https://publicsuffix.org/list/effective_tld_names.dat

What is a better way to capture the domain name? The goal is to remove the subdomain, extract the domain name so I can resolve or ping it.

Aside from the non-C++-ness of your code, the exact problem is that name is a pointer to chars, and "" is an array of chars. The code name == "" returns false, since name does not point to the first char in the array. Instead, you'll want to check if already allocated array is empty, by checking if the NULL terminator is the first character. if (name[0] == '\0')

Now for the C++ ness: don't use char*, use std::string. Also, your code to keep prompting if you got invalid data is backwards.

24727701 0 adding a column to a table with different parameters

I am trying to enter 2 tables into one output my problem is that the parameter is pulling from 2 different columns. I need to be able to show what was completed and the work ordered for a months period. I do not get any errors as the script is written but after 3 hours I stopped it from running.

If I change the join on the @Ordered to iAuditID from EffectiveDate it takes a few seconds to run, but it does not pull the correct information then. I only need the count of ordered audits to be correct and in the @data table and correct. Work may have been ordered a few months before it was completed, therefore I need to be able see how much work is coming in each month and what is being completed.

I am using SQL 2008.

DECLARE @StartDate datetime, @EndDate datetime, @iClientID int, @iServiceLevelID int SET @StartDate = '1-1-13' SET @EndDate = '12-30-13' SET DATEFIRST 7 DECLARE @TB1 TABLE (EffectiveDate datetime, iAuditID int, iClientID int, iServiceLevelID int) INSERT INTO @TB1 SELECT dateadd(month, datediff(month, 0, a.dtClosedDate),0) AS EffectiveDate, a.iAuditID, a.iClientID, a.iServiceLevelID FROM vwtblAudit a WHERE (a.dtClosedDate >= @StartDate) AND (a.dtClosedDate <= @EndDate) AND (a.iClientID = @iClientID OR @iClientID is null) AND (a.iServiceLevelID = @iServiceLevelID or @iServiceLevelID is null) GROUP BY dateadd(month, datediff(month, 0, a.dtClosedDate),0), a.iClientID, a.iAuditID, a.iServiceLevelID DECLARE @Ordered TABLE (EffectiveDate datetime, iAuditID int, iClientID int, iServiceLevelID int, dtOpenDate int) INSERT INTO @Ordered SELECT dateadd(month, datediff(month, 0, a.dtOpenDate),0) AS EffectiveDate, a.iAuditID, a.iClientID, a.iServiceLevelID, Count(a.dtOpenDate) as Ordered FROM tblAudit a WHERE (a.dtOpenDate >= @StartDate) AND (a.dtOpenDate <= @EndDate) AND (a.iClientID = @iClientID OR @iClientID is null) AND (a.iServiceLevelID = @iServiceLevelID or @iServiceLevelID is null) GROUP BY dateadd(month, datediff(month, 0, a.dtOpenDate),0), a.iClientID, a.iServiceLevelID, a.iAuditID order by iClientID, EffectiveDate DECLARE @DATA table(iclientID int, sClientCode varchar(8), sClientName varchar(50), iServiceLevelID int, sServiceLevelName varchar(50), EffectiveDate datetime, iAuditCount int, Completed int) SELECT tblClient.iclientID, tblClient.sClientCode, tblClient.sClientName, tblServiceLevel.iServiceLevelID, TB1.EffectiveDate, COUNT(*) AS iAuditCount, COUNT(Ordered.dtOpenDate) as Ordered FROM @TB1 TB1 INNER JOIN tblClient ON TB1.iClientID = tblClient.iClientID INNER JOIN tblServiceLevel ON TB1.iServiceLevelID = tblServiceLevel.iServiceLevelID join @Ordered Ordered on TB1.EffectiveDate=Ordered.EffectiveDate GROUP BY tblClient.iClientID, TB1.iServiceLevelID, tblclient.sClientCode, tblClient.sClientName, tblServiceLevel.iServiceLevelID, tblServiceLevel.sServiceLevelName, TB1.EffectiveDate return SET DATEFIRST 7

Every a from the @data worked like it should, but I was ask to add the work coming in, so I added @ordered table to bring in the correct information. The data is still correct except for the ordered column. See sample below:

clientID ClientCode ClientName iServiceLevelID EffectiveDate iAuditCount Ordered 0001 1001 Sample 1 Jan 2014 104 19(this number should be 134)

You have one serious problem here:

struct sockaddr_in *local = malloc(sizeof (struct sockaddr_in *));

because you're just allocating the size of a pointer instead of the size of the struct itself.

This should of course be:

struct sockaddr_in *local = malloc(sizeof (struct sockaddr_in));

Two more problems with the same variable in this line:

 if (bind(s, (struct sockaddr *)&local, sizeof(local)) < 0)

This should be:

 if (bind(s, (struct sockaddr *)local, sizeof(*local)) < 0)

It seems when you try to add more elements to it, and it needs to allocate more space, it does so by copying the last element it currently holds. This seems to assume that any element in the vector is fully valid, and as such a copy will always succeed.

Both sentences are not really correct. When vector runs out of space it, yes, performs reallocation, but of all the elements and these are copied to the new location or possibly moved. When you push_back or emplace_back, and reallocation is needed, the element will generally by copied: if an exception is thrown during that, it will be treated as if you had never added the element. If vector detects a noexcept user-defined move constructor ( MoveInsertable concept), elements are moved; if this constructor though is not noexcept, and an exception is thrown, the result is unspecified.

The objects have guards, but I never considered adding guards to a copy constructor as I assumed we would never be copying an invalid object (which vector forces) :

vector copies its value_type: it does not care whether what it contains is valid or invalid. You should take care of that in your copy control methods, whose scope is exactly to define how the object is passed around.

CopiedClass::CopiedClass(const CopiedClass& other) : member(other.member) { member->DoSomething(); }

The obvious solution would be to check if member is valid and act thereby.

if (member.internalData.isValid()) member->DoSomething() // acknowledge this.member's data is invalid

We don't know how member is represented, but Boost.Optional is what you may be looking for.

Is it possible to prevent std::vector from copying that element?

Reallocation is something vector is expected to commit so, no, you can't. reserv-ing space could avoid that, but maintaining code to handle that would not really be painless. Rather, prefer a container like std::forward_list/std::list.

Clarification:

The function introducir_datos() expects to be given an array of 30 struct agenda items as its argument.

This means that the argument type is struct agenda*, because you are sending a pointer to the first item in the array. (This is just how arrays work in C.)

You can't call this function with a char[] array as the argument, because a char[] array consists of char variables. A char doesn't have any nombre, apellido, direccion, edad or telefono members.

So your code won't compile because the compiler can't figure out what you're trying to do.

Incidentally, although you declare the variable int x; in introducir_datos(), you don't initialize it anywhere, so you need to fix that too.

Assume you defined a object named Foo,

message Foo { ... }

If you want to send a list of Foo, you can make it a repeated field in another message,

message FooList { repeated Foo foos = 1; }

You can check the language guide ,

You specify that message fields are one of the following: required: a well-formed message must have exactly one of this field. optional: a well-formed message can have zero or one of this field (but not more than one). repeated: this field can be repeated any number of times (including zero) in a well-formed message. The order of the repeated values will be preserved.

Do you have another thread that is iterating/modifying the key set of Selector? From the Selector's java doc, keys are NOT threadsafe.

Concurrency

Selectors are themselves safe for use by multiple concurrent threads; their key sets, however, are not. ...

You may get CME exception If you have a thread working on the key set while Selector.close() is being called. Looking at the stack trace, the exceptions are happening in Sun's common implementation codes, so it shouldn't be AIX specific implementation. My suggestion would be identifying the thread that is add/removing selector keys, and see if synchronized keyword needs to be applied, or you need to make a sync-copy before working on the keys. If the modifying thread is not your thread/codes, then it is AIX issue. However, I can't tell without seeing the codes that modifying the key set.

Good luck debugging. I hope it helps

I'm currently working on a mobile application with Intel XDK (In background it's Cordova finally, that's why I put Cordova in title.)

With an Ajax request, I get some adresses and with these adresses I want to calculate the distance between them and the current position of user.

So, I get adresses, I convert them and I make the difference.

But actually, nothing is working !

In the console.log(id), console.log(addresse), I HAVE results !

Actually i'm getting 4 IDs and 4 adresses.

I checked on all the topics I could find on StackOverFlow, and I had normally to add the line in // with the addEventListener but it changes nothing.

Is there someone who knows how to change that ?

ps : Of course, cordova geoloc is in the build and permissions are granted !

 #include <iostream> using namespace std; class TestScores { public: TestScores(); TestScores(int scores); ~TestScores(); void AddScore(int newScore); void DisplayArray(); void SortScores(); bool ArraySorted(); int AvgScore(); private: int *scoresArray; //Dynamically allocated array int numScores; //number of scores input by user int scoreCounter; const static int default_NumArrays=10; //Default number of arrays }; #include <iostream> #include "TestScores.h" TestScores::TestScores() { scoresArray=new int[default_NumArrays]; scoreCounter=0; numScores=default_NumArrays; } TestScores::TestScores(int scores) { scoresArray=new int[scores]; numScores=scores; scoreCounter=0; for(int i=0; i<scores;i++) scoresArray[i]=0; } TestScores::~TestScores() { delete[] scoresArray; } void TestScores::AddScore(int newScore) { if(scoreCounter<numScores){ scoresArray[scoreCounter]=newScore; scoreCounter++; } else cout<<"More scores input than number of scores designated"<<endl; } void TestScores::DisplayArray() { for(int i=0; i<numScores; i++) cout<<scoresArray[i]<<endl; cout<<endl<<"This is scoresArray"<<endl; } bool TestScores::ArraySorted() { for(int i=0; i<(scoreCounter-1);i++){ if(scoresArray[i]<=scoresArray[i+1]) continue; else return false; } return true; } void TestScores::SortScores() { int tempValue; while(ArraySorted()!=true){ for(int i=0; i<(scoreCounter-1); i++){ if(scoresArray[i]<=scoresArray[i+1]) continue; else{ tempValue=scoresArray[i+1]; scoresArray[i+1]=scoresArray[i]; scoresArray[i]=tempValue; } } } } int TestScores::AvgScore() { int sumScores=0; if(scoreCounter>0){ for(int i=0; i<scoreCounter; i++) sumScores+=scoresArray[i]; return (sumScores/scoreCounter); } else{ cout<<"There are no scores stored."<<endl; return 0; } } #include "TestScores.h" #include <iostream> #include <fstream> #include <string> using namespace std; //Function prototypes bool FileTest(ifstream& inData); void StoreScores(ifstream& inData, int& newNumScores, TestScores satScores); int main() { int newNumScores=0; string inputFile; //Contains name of the user file being used //Opening file stream ifstream inData; //User prompt for input file cout<<"Please enter the file name containing the student scores you wish to " <<"have stored, sorted, and displayed."<<endl; cin>>inputFile; //Opening file streams inData.open(inputFile.c_str()); while(FileTest(inData)==false){ cout<<"I'm sorry, the file you entered was not a valid file. " <<"Please enter another file name, or enter q to exit"<<endl; cin>>inputFile; if(inputFile=="q") return 0; //Opening file streams inData.open(inputFile.c_str()); } inData>>newNumScores; TestScores satScores(newNumScores); //Instantiating TestScores variable StoreScores(inData, newNumScores, satScores); //Storing scores into array satScores.DisplayArray(); satScores.SortScores(); satScores.DisplayArray(); cout<<endl<<"This is the array after sorting"<<endl<<endl; cout<<"This is the average score "<<satScores.AvgScore()<<endl; //Program pauses for user input to continue char exit_char; cout<<"\nPress any key and <enter> to exit\n"; cin>>exit_char; inData.close(); return 0; } bool FileTest(ifstream& inData) { if(!inData) { cout<<"Your file did not open.\n"; return false; } return true; } void StoreScores(ifstream& inData, int& newNumScores, TestScores satScores) { int userScore; while(inData>>userScore){ satScores.AddScore(userScore); } }

My test file is random.dat and contains the following:

15 67 76 78 56 45 234

Based on looking through the debugger, I can tell that scoreCounter is incrementing correctly and that newScore contains the next value, so why isn't it being stored in the array? Thanks for the help

var level=0; var levelarray=[]; function looptrough(obj){ for(key in obj){ if(typeof obj[key]=="object"){ level++; looptrough(obj[key]); level--; } levelarray[level]=levelarray[level] || {}; levelarray[level][key]=obj[key]; } } looptrough({a:true;b:{c:true}});

Levelarray should now contain:

0:{a:true;b:{c:true}} 1:{c:true}

I thought using jquery is quite unecessary in that case, thats why i used for in...

26983931 0 Dynamic input form php

I am making a dynamic PHP form that interacts with a mySQL database for entering the scores of students on different assignments. So far I have successfully connected to the database and accessed the necessary data. The following code displays for each student first, their name, and then an empty text input box where the user enters the score said student earned on the assignment.

<?php if(isset($_POST["beginScoring"]) || isset($_POST['submitScores'])){ $result = $connection->query("SELECT id, firstname, lastname FROM student ORDER BY lastname"); if(!$result) { echo "Query Failure"; } else { $foo = array(); $c = 0; echo "<tr><td>Last Name</td><td>First Name</td><td>Points Earned</td></tr>"; while ($row = $result->fetch_assoc()) { echo "<tr><td>$row[lastname]</td><td>$row[firstname]</td>"; ?> <td><input type="text" size=8 name="" id="" value=""/></td></tr> <!-- I can maybe use an array to store scores . . . --> <?php } } ?>

The thing I am having issues with is how do I name the text input. Since there are going to be an undetermined amount of text boxes, I can't use a single static name for the input item, right? What would be a good way to name the text boxes so that I can easily access them using the POST array?

6545244 0 RichTextToolbar in GWT 2.3

I'm trying to create a RichTextArea (following the GWT Showcase : link )

When I do a code completion of RichTextToolbar, I'm not able to find it. Is this an external library?

And then I googled and found this : google code link. Is this the same library in the Google Showcase? Or is the RichTextToolbar is an old implementation that not being brought to version 2.3?

Update:I tested this and what I feel is although the implementation the same, the UI looks different though.

If you are compiling your code for Any CPU, a x64 tries to load native, external DLLs as x64 version. That might be problematic if that DLL is 32-bit. It throws an exception.
Yes, you can build it as Any CPU
s. 1
It (can) internally use x64 advantages of the operating system like 4GB+ memory etc.
No, this is done by .NET installer by default.

26551784 0 Browserify Bootstrap jQuery modal undefined is not a function

File: test.jsx compiles to bundle.js using Gulp and Browserify.

File: test.jsx:

var $ = require('jquery'); $("div#addTagModal").modal("hide");

In browser when I load the page I get this error:

Uncaught TypeError: undefined is not a function

On this line:

 $("div#addTagModal").modal("hide");

I have no clue what is wrong. :/

$.ajax works fine so I assume that jQuery is loaded properly.

Bootstrap is included in html using a script tag and I have checked the ID of modal.

I have a button that once clicked opens that modal:

<button className="btn btn-success" data-toggle="modal" href="#addTagModal" type="button"> <i class="icon-plus"></i> </button>

Any ideas?

This is my gulp task:

gulp.task('browserify', function() { gulp.src('app/assets/js/main.js') .pipe(browserify({ debug : true, transform: ['reactify'] })) .on('error', gutil.log) .pipe(rename('public/js/bundle.js')) .pipe(gulp.dest('./')) });

And in main.js I have this code:

var app = require('./test.jsx');

Your first foreach() is causing the issue, as it is looping through both subarrays before printing the second foreach loop. Try removing it, and just reference the first $v['kaupunki_id'] using $values[0]['kaupunki_id'] -

$numerointi =1; echo "<table class=\"zebra\">"; foreach($arrayTotals as $team=>$values){ echo "<tr class=\"" . $values[0]['kaupunki_id'] . "\"><td>".$numerointi ."."; echo "<td>" . $team; $sum1=0; $sum2=0; $numerointi ++; foreach($values as $v){ echo "<td class=\"pisteet\">" . $v['pisteet_1'] . "/" . $v['pisteet_2'] . "</td>"; $sum1 +=$v['pisteet_1']; $sum2 +=$v['pisteet_2']; } echo '<td class="summa">'.$sum1.'/'.$sum2."</td>"; echo "</tr>"; } echo '</table>';

18158051 0 Search Replace in MySQL: remove directory structure but keep filename

I am changing directory structures in a Drupal installation and need to remove all path data except the file name itself.

So the basic structure is:

+-------------+--------------+---------+-----------+-------------+----------+-------+----------------------------------------------------------------------------------+-----------------------+ | entity_type | bundle | deleted | entity_id | revision_id | language | delta | field_filename_value | field_filename_format | +-------------+--------------+---------+-----------+-------------+----------+-------+----------------------------------------------------------------------------------+-----------------------+

The filename is stored in field_filename_value. Here's a sample record:

+-------------+--------------+---------+-----------+-------------+----------+-------+----------------------------------------------------------------------------------+-----------------------+ | entity_type | bundle | deleted | entity_id | revision_id | language | delta | field_filename_value | field_filename_format | +-------------+--------------+---------+-----------+-------------+----------+-------+----------------------------------------------------------------------------------+-----------------------+ | node | presentation | 0 | 11 | 11 | und | 0 | /really long path name/with lots of words/167 Clarence Ashley - Coo Coo Bird.mp3 | NULL | +-------------+--------------+---------+-----------+-------------+----------+-------+----------------------------------------------------------------------------------+-----------------------+

That ridiculous filename value needs to be changed from:

 /really long path name/with lots of words/167 Clarence Ashley - Coo Coo Bird.mp3

To this:

 167 Clarence Ashley - Coo Coo Bird.mp3

Setting aside the bad practice of using spaces in file/directory names, how would you correct this? Is it possible using MySQL features alone?

As an added challenge, some files may be more than 2 directories deep.

I use process.on(uncaughtException), because all you're really trying to do is catch the output from the error and shut the server down gracefully (and then restart). I don't see any reason to do anything more complicated than that, because by nature of the exception, you don't want your application doing anything else in that state other than shutting down.

Domains are an alternative way of dealing with this, but it's not necessarily better than using the process handler, because you're effectively writing custom logic to handle things that you aren't anticipating. It does give you finer granularity in terms of what your error handler does for different error types, but ultimately you're still potentially running your application in an unknown state after handling it. I'd rather have my application log the exception, shut down, and then i'll fix the error so it never happens again, rather than risking my user's data on a domain solution which may or may not have handled the error correctly, depending on the nuance of the error it encountered.

Three observations.

The best speedups are not coming from optimizations but from good algorithms. So make sure you get that part right first. Often this means just using the right libraries for your specific domain.
Once you get your algorithms right it is time to Measure. Often there is an 80/20 rule at work. 20% of your code will take 80% of the execution time. But in order to locate that part you need a good profiler. Intel VTune can give you sampling profile from every function and nice reports that pinpoint the performance killers. Another free alternative is AMD CodeAnalyst if you have an AMD CPU.
The compiler autovectorization capability is not a silver bullet. Although it will try really hard (especially Intel C++) you will often need to help it by rewriting the algorithms in vector form. You can often get much better results by handcrafting small portions of the bottleneck code to use SIMD instructions. You can do that in C code (see VJo's link above) using intrinsics or use inline assembly.

Of course parts 2 and 3 form an iterative process. If you are really serious about this then there are some good books on the subject by Intel folks such as The Software Optimization Cookbook and the processor reference manuals.

You could also write an iterator for your matrix. This is not complete but gives you an idea:

It's taken the best bits from JavaScriptMVC and distilled it into one small, yet kickass framework with observers, widgets, binding, the works. It is compatible with major frameworks (jQuery, Dojo Toolkit, MooTools, etc.). Documentation is excellent and authors are responsive. It is definitely worth a look.

I use the following for sorting a 2d array on a number of columns

def k(a,b): def _k(item): return (item[a],item[b]) return _k

This could be extended to work on an arbitrary number of items. I tend to think finding a better access pattern to your sortable keys is better than writing a fancy comparator.

>>> data = [[0,1,2,3,4],[0,2,3,4,5],[1,0,2,3,4]] >>> sorted(data, key=k(0,1)) [[0, 1, 2, 3, 4], [0, 2, 3, 4, 5], [1, 0, 2, 3, 4]] >>> sorted(data, key=k(1,0)) [[1, 0, 2, 3, 4], [0, 1, 2, 3, 4], [0, 2, 3, 4, 5]] >>> sorted(a, key=k(2,0)) [[0, 1, 2, 3, 4], [1, 0, 2, 3, 4], [0, 2, 3, 4, 5]]

You could either use setInterval:

window.setInterval(jTTrackPage, 10000); // call it every 10 000 ms = 10 s

or setTimeout:

function trackPage() { jTTrackPage(); window.setTimeout(trackPage), 10000); // call the function again in 10 000 ms } trackPage();

The difference between both is that the first one calls it every 10s, and if one call takes more than 10s (unlikely here) the next one will be triggered just after, without waiting 10s. The second solution solves this problem.

You can clear an interval or a timeout using respectively clearInterval and clearTimeout:

var interval = window.setInterval(jTTrackPage, 10000); window.clearInterval(interval); // <-- stop it var timeout = window.setTimeout(trackPage, 10000); window.clearTimeout(timeout); // <-- stop it

Swift is designed to take advantage of optional value's and optional unwrapping.

You could also declare the array as nil, as it will save you a very small (almost not noticable) amount of memory.

I would go with an optional array instead of an array that represents a nil value to keep Swift's Design Patterns happy :)

I also think

if let children = children { }

looks nicer than :

if(children != nil){ }

Answering the (original) question ("Does Perl have an equivalent to PHP's readline() function ... ?"), the answer is "the angle bracket syntax":

open my $fh, '<', '/path/to/file.txt'; while (my $line = <file>) { print $line; }

Getting the content-length with this method isn't necessarily easy, though, so I'd recommend staying with Tie::File.

NOTE

Using:

for my $line (<$filehandle>) { ... }

(as I originally wrote) copies the contents of the file to a list and iterates over that. Using

while (my $line = <$filehandle>) { ... }

does not. When dealing with small files the difference isn't significant, but when dealing with large files it definitely can be.

Answering the (updated) question ("Does Perl have an equivalent to PHP's readfile() function ... ?"), the answer is slurping. There are a couple of syntaxes, but Perl6::Slurp seems to be the current module of choice.

The implied question ("why doesn't the browser prompt for download before grabbing the entire file?") has absolutely nothing to do with how you're reading in the file, and everything to do with what the browser thinks is good form. I would guess that the browser sees the mime-type and decides it knows how to display plain text.

Looking more closely at the Content-Disposition problem, I remember having similar trouble with IE ignoring Content-Disposition. Unfortunately I can't remember the workaround. IE has a long history of problems here (old page, refers to IE 5.0, 5.5 and 6.0). For clarification, however, I would like to know:

What kind of link are you using to point to this big file (i.e., are you using a normal a href="perl_script.cgi?filename.txt link or are you using Javascript of some kind)?
What system are you using to actually serve the file? For instance, does the webserver make its own connection to the other computer without a webserver, and then copy the file to the webserver and then send the file to the end user, or does the user make the connection directly to the computer without a webserver?
In the original question you wrote "this does not cause the browser to prompt for download before grabbing the entire file" and in a comment you wrote "I still don't get a download prompt for the file until the whole thing is downloaded." Does this mean that the file gets displayed in the browser (since it's just text), that after the browser has downloaded the entire file you get a "where do you want to save this file" prompt, or something else?

I have a feeling that there is a chance the HTTP headers are getting stripped out at some point or that a Cache-control header is getting added (which apparently can cause trouble).

Inside the web.config file in the Views folder there is the host element under system.web.webPages.razor

This should be as follows for an MVC3 project:

<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

While for MVC4 it is:

<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

You also need to check the pages element is as follows for MVC3

<pages validateRequest="false" pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <controls> <add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" namespace="System.Web.Mvc" tagPrefix="mvc" /> </controls> </pages>

and the sectionGroup element:

<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" /> <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" /> </sectionGroup>

In the main web.config in the root directory of the project you need to make sure that the assemblies element is as follows:

<assemblies> <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </assemblies>

There are more changes to make - best bet is to look at the web.config files for an MVC3 project and an MVC4 project and remove the stuff that shouldn't be there in yours.

The characters that represent decimal digits are laid out in ASCII space in numerical order.

'0' is ASCII 0x30
'1' is ASCII 0x31
'2' is ASCII 0x32
and so on.

This means that you can simply subtract '0' from your character to get the value you desire.

char a = ...; if (a >= '0' && a <= '9') { int digit = a - '0'; // do something with digit }

So first i create my model/db with EF.

Then I create Views (either user controls or windows) with their respective viewmodel. I usually place the viewmodel in the same location as my view. But while starting the name of my view with "UC-name", I call my viewmodel just "name-model".

In my viewmodel I implement InotifyPropertyChanged

in my xaml view I have a resource of my viewmodel, and bind my grids/controls via the itemsource to the staticresource.

I try to do a lot of front end logic with triggers and styles and also place some code in the xaml.cs file if it regards logic for behaviour of my controls.

I can reach my viewmodel from my view (xaml + xaml.cs).

for communiation between viewmodels I use MVVM lights.

that's pretty much it.

Things I'm thinking about

I'm thinking of using T4 templates for generating viewmodel/view. What do you guys think of this. is this worth it?
when using MVVM light Messenger, we get a subscription based communication, and sometimes I find it hard to track what has changed in my DataContext. Any suggestions on this?
any other improvements or suggestions are more than welcome !

You could use a make file to generate the .i files first, run your processing on them, then compile them.

8302923 0 new created UIImageViews do not show up when added as subview

upon a tap, I want to let a few UIImageView objects appear on an underlaying UIView. So I created the following action:

- (IBAction)startStars: (id) sender { UIView* that = (UIView*) sender; // an UIButton, invisible, but reacting to Touch Down events int tag = that.tag; UIView* page = [self getViewByTag:mPages index:tag]; // getting a page currently being viewed if ( page != nil ) { int i; UIImage* image = [UIImage imageNamed:@"some.png"]; for ( i = 0 ; i < 10 ; ++i ) { // create a new UIImageView at the position of the tapped UIView UIImageView* zap = [[UIImageView alloc] initWithFrame:that.frame]; // assigning the UIImage zap.image = image; // make a modification to the position so we can see all instances CGPoint start = that.layer.frame.origin; start.x += i*20; zap.layer.position = start; [page addSubview:zap]; // add to the UIView [zap setNeedsDisplay]; // please please redraw [zap release]; // release, since page will retain zap } [image release]; } }

Unfortunately, nothing shows up. The code gets called, the objects created, the image is loaded, even the properties are as expected. Page itself is a real basic UIView, created with interface builder to contain other views and controls.

Still, nothing of this can be seen....

Has anyone an idea what I am doing wrong? Do I need to set the alpha property (or others)?

Thanks

ed is the standard text editor.

#!/bin/bash { ed -s file.json <<EOF /\"fruit\": \[ a { "fruit":"apple" , "amount":"10" } #object to add . wq EOF } &> /dev/null

Don't know why you want to use bash for that, though, there are much better tools around!

Done.

You can use:

private float x; public float X { get { return x; } }

Now you only set x from within your class.

I was missing one line

The rest was the same as the answer.

6415740 0 Rails 3 update routing error

I am having trouble with my routing in a Rails application.

My routing file has:

resources :translations

Which should create several routes, including update.

Doing a rake routes shows the update route is there:

PUT /translations/:id(.:format) {:action=>"update", :controller=>"translations"}

However, when I use the following code to link to the update:

<% form_tag( {:controller => "translations", :action => "update"}, {:multipart => true}) do %> <p><%= label_tag "upload", translate("UI_TEXT_FORM_SELECT_AUDIO_FILE") %>: <%= file_field_tag "upload" %></p> <%= submit_tag translate("UI_TEXT_FORM_SAVE") %> <% end %>

I get this result:

Routing Error No route matches "/translations/10"

Any help would be appreciated.

Try changing viewController = [[PhotoViewController alloc] init]; to

viewController = [[PhotoViewController alloc] initWithNibName:@"PhotoViewController" bundle:nil];

(of course change the text string to whatever you called your xib file).

All associated data with an extension is removed when the extension is uninstalled. You can verify this by visiting your Chrome profile directory, and descend in Local Storage. You'll see a SQLLite database (eg. chrome-extension_lndfmdleiloedhcbmjofibnflfbjhpha_0.localstorage).

After removing the extension, this database disappears.

If you need to receive sms during application opened (not as service), you can put Receiver in Main activity as mentioned in hewwcn answer.

For example:

public class MainActivity extends Activity { /* * Variables for BroadcastReceiver */ boolean isRegistered = false; // check if BroadcastReceiver registered private IntentFilter filterSmsReceived = new IntentFilter( "android.provider.Telephony.SMS_RECEIVED"); /** * Create BroadcastReceiver */ private BroadcastReceiver smsReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals( "android.provider.Telephony.SMS_RECEIVED")) { /* get the SMS message passed in */ Bundle bundle = intent.getExtras(); SmsMessage[] msgs = null; String msgFrom = null; String msgBody = null; if (bundle != null) { /* retrieve the SMS message received */ try { Object[] pdus = (Object[]) bundle.get("pdus"); msgs = new SmsMessage[pdus.length]; for (int i = 0; i < msgs.length; i++) { msgs[i] = SmsMessage .createFromPdu((byte[]) pdus[i]); msgFrom = msgs[i].getOriginatingAddress(); msgBody = msgs[i].getMessageBody(); } /* * TODO Show dialog */ } catch (Exception e) { // Log.d("Exception caught",e.getMessage()); } } } } }; /** * Button - register BroadcastReceiver when clicked (or put it to onCreate) */ public void onButtonClicked(View v) { this.registerReceiver(smsReceiver, filterSmsReceived); isRegistered = true; } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } @Override protected void onPause() { /* * Unregister BroadcastReceiver */ if (isRegistered) { this.unregisterReceiver(smsReceiver); isRegistered = false; } super.onPause(); } @Override protected void onDestroy() { /* * Unregister BroadcastReceiver */ if (isRegistered) { this.unregisterReceiver(smsReceiver); isRegistered = false; } super.onDestroy(); } }

6928335 0 Apache Mina , create my own IoSession: How to?

I'm playing for a few days with apache mina and I want to ask you how can I create by extending (or implementing) IoSession to create something like MyIoSession.

The reason why I want to do this is because in the Handler class I want something like this:

public class MyHandler extends IoHandlerAdapter{ public void messageReceived( MyIoSession session, Object message ) throws Exception { // here I have MyIoSession instead of IoSession which will have more info something // like an unique ID } }

This way MyIoSession will have some unique ID and this way I'll identify which client is sending messages to server.

Also if there are other better ways to achieve this feel free to tell me.

Thanks

If I was you, I would keep the last fetched id from the dataset.

Therefore you need to change your Controllers.OdbcController.GetRecords() to accept an id and return the latest one.

In the GetRecords check for that id using a where clause.

EDIT:

According to your update: are you sure the ID gets passed to the config correctly?

You use two different calls to save and retrieve:

ConfigurationManager.AppSettings["LastId"]

vs.

Common.UpdateConfigFile.UpdateAppSetting("LastId", _lastId)

Why not use this?

ConfigurationManager.AppSettings["LastId"] = _lastId;

In general, thrust operations dispatched on the "host" are not run in parallel. They use a single host thread.

If you want to run thrust operations in parallel on the CPU (using multiple CPU threads) then the recommended practice would be to use the thrust OpenMP backend.

33198428 1 jwt: 'module' object has no attribute 'encode'

I am getting Module not found error when using jwt. Here is how I declared it:

def create_jwt_token(): payload = { "iat": int(time.time()) } shared_key = REST_API_TOKEN payload['email'] = EMAIL payload['password'] = PASSWORD jwt_string = jwt.encode(payload, shared_key) encoded_jwt = urllib.quote_plus(jwt_string) # url-encode the jwt string return encoded_jwt

The error message says encode is not found in jwt. I did a tab on jwt and found that the encode is a method inside jwt.JWT. I tried changing it to

jwt_string = jwt.JWT.encode(payload, shared_key)

and it gives an error "unbound method encode() must be called with JWT instance as first argument (got dict instance instead)"

For the XSLT part I recommend using the "Fill-in the blasnks" technique -- see a simple example here: http://stackoverflow.com/a/8674694/36305.

The form skeleton will look like this:

<form name="formRoot" xmlns:gen="my:gen"> <gen:name/> </form>

The XSLT code will contain a template matching gen:name that produces:

<p>Name</p><input name="name" value="Name"/>

The URL to the form-skeleton is passed as an external parameter to the XSLT transformation.

The source XML document (URL or itself) is passed as another external parameter.

Thus the XSLT transformation can process any source XML document and insert the results of processing into any form-skeleton document.

I had the same problem in a different way.After I updated the row in the 3. page, the table used to go back to 1. page automatically.. The forth parameter of the fnUpdate takes true/false to update the table and default value is true. I changed it as false then it has started working. Not exactly the same situation you experienced but might help to solve your problem. Have a look at the parameters of the functions that you used in your code.Regards. Ozlem.

Here's one way using regular expressions. First, make sure the price column is a character vector and not a factor

DB1$price<-as.character(DB1$price)

Then define your desired replacements

replacewith<-c("Jan"="1.", "Feb"="2.", "Mrz"="3.", "Apr"="4.", "Mai"="5.", "Jun"="6.", "Jul"="7.", "Aug"="8.", "Sep"="9.", "Okt"="10.", "Nov"="11.", "Dez"="12.")

Now turn those into a regular erxpression and match against your price column

re <- paste0("^(",paste(names(replacewith),collapse="|"), ") ") m <- regexpr(re,DB1$price, perl=T) mm <- regmatches(DB1$price, m)

Now we do a look up for the replacement

regmatches(DB1$price, m) <- replacewith[substr(mm, 1, nchar(mm)-1)] DB1$price # [1] "12.90" "8.90" "3.40" "79.95" "12.45" "7.99" "6.90" "129.90" "7.90" "49.95"

9754228 0 how to initialize private members of class in c++

Hi i have a c++ class with some private members as follows

 template <typename V, typename E> class Vertex { public: Vertex(); ~Vertex(); typedef std::pair<int, E> edgVertPair; typedef std::vector<edgeVertPair> vectEdges; void setVertexID(int data); int getVertexID(); void setEdgeVertPair(int vertID, E edge); edgVertPair getEdgeVertPair(); void setEdgeList(edgeVertPair edgeVert); vectEdges getEdgeList(); private: int vertexID; edgVertPair evp; vectEdges edgeList; };

Now i want to create a pair i.e. something like

evp.first="someint"; evp.second="somestring";

and then push this evp into the edgeList i.e. edgeList.push_back(evp); Now the problem is in the setter function i did something like this:

 template<typename V, typename E> void Vertex<V, E>::setEdgeVertPair(int vertID, E edge){ ...populate evp;... }

now i don't know how to populate the evp pair with vertID, edge.

what you can do is every step, save out the form state to some serialised object in db ForeignKeyed to the user.

then when hooking up the formwizard, wrap the formwizard view in a custom view which checks if the user has a saved form and if so deserialises and redirects to the appropriate step.

Edit: seems formwizard saves state in POST. only need to save postdata.

models.py:

class SavedForm(Model): user = ForeignKey(User) postdata = TextField()

views.py:

import pickle class MyWizard(FormWizard): def done(self, request, form_list): SavedForm.objects.get(user=request.user).delete() # clear state!! return render_to_response('done.html',) formwizard = MyWizard([Form1, Form2]) <- class name, not instance name def formwizard_proxy(request, step): if not request.POST: #if first visit, get stored data try: prev_data = SavedForm.objects.get(user=request.user) request.POST = pickle.loads(prev_data.postdata) except: pass else: # otherwise save statet: try: data = SavedForm.objects.get(user=request.user) except: data = SavedForm(user=request.user) data.postdata=pickle.dumps(request.POST) data.save() return formwizard(request)

edit: changed formwizard constructor

You can do as follows :

add javascript into local.xml

<layout version="0.1.0"> <default> <reference name="head"> <action method="addJs"><script>jquery/jquery-1.7.1.min.js</script></action> <action method="addJs"><script>jquery/carouFredSel.js</script></action> </reference> </default> </layout>

then make a custom home page template ( take reference from 1column.phtml ), select this template for homepage from CMS.

Put the following content in home page "XML Layout Update" section from Design tab. Here is mine setting which I remove whole prototype scripts from homepage is because didn't want.

<reference name="head"> <action method="removeItem"><type>js</type><script>prototype/prototype.js</script></action> <action method="removeItem"><type>js</type><script>prototype/validation.js</script></action> <action method="removeItem"><type>js</type><name>scriptaculous/builder.js</name><params/></action> <action method="removeItem"><type>js</type><name>scriptaculous/effects.js</name><params/></action> <action method="removeItem"><type>js</type><name>scriptaculous/dragdrop.js</name><params/></action> <action method="removeItem"><type>js</type><name>scriptaculous/controls.js</name><params/></action> <action method="removeItem"><type>js</type><name>scriptaculous/slider.js</name><params/></action> <action method="removeItem"><type>js</type><name>lib/ccard.js</name><params/></action> <action method="removeItem"><type>js</type><name>varien/menu.js</name><params/></action> <action method="removeItem"><type>js</type><name>varien/js.js</name><params/></action> <action method="removeItem"><type>js</type><name>mage/translate.js</name><params/></action> <action method="removeItem"><type>js</type><name>varien/form.js</name><params/></action> <action method="removeItem"><type>skin_js</type><script>js/prototype.formalize.min.js</script></action> <action method="removeItem"><type>skin_css</type><name>css/formalize.css</name><params/></action>

Also, don't create a specific noConflict page, just put end of the jQuery script which is working well.

For instance, here is mine :

jQuery&&define("jquery",[],function(){return f})})(window);var $jQuery = jQuery.noConflict();

Also, yu should create jquery folder in root js directory, not in skin folder js directory.

That's a floating point number. Unlike any other language I've ever encountered, all numbers in Javascript are actually 64-bit floating numbers. Technically, there are no native integers in Javascript. See The Complete Javascript Number Reference for the full ugly story.

of course you can store it in a local variable and assign only if valid. But since you're calling exit(0) if invalid it doesn't change anything. I suppose you want to break from the loop instead.

BTW your loop is wrong. you have to divide sizeof(numArray) by the size of one element otherwise you'll loop too many times and you'll crash the machine if there are too many numbers in your input file (yes, I also added a test for end-of-file)

if (myFile != NULL) { for (int i = 0; i < sizeof(numArray)/sizeof(numArray[0]); i++) { int x; //insert int to array if (fscanf(myFile, "%d", &x)==0) { printf("Invalid number found / end of file, closing application...\n"); exit(0); // end of file / not a number: stop } //Validate number if (x > 25) { printf("Invalid number found, closing application...\n"); exit(0); } numArray[i] = x; } //close file fclose(myFile); }

Is there a way that I can replicate the data that I need and delete those documents from couchdb, as couchdb grows a lot and fills my webspace in a flash.

For those who may know what software and what I want to do, I'm trying to get ecoinpool to work with a php frontend like simplecoin. If that fails how hard is it to get a php, already developed and working with mysql, website working with couchdb?

22335272 0 Exception handling Try Catch block

I have been reading about exceptions for the past couple of hours and have a basic understanding. However the book I'am reading hasn't got the best examples when it comes to showcasing the coding aspects. I know that if I have code that could fail I wrap it in a try block and the catch the exceptions specifically i.e FormatException etc.

However the confusing part is when it comes to call stack were for e.g Method A calls Method B and Method B calls method C etc.

For example a exception occurs in Method c but it doesn't have a catch handler so it propagates back to the calling method so on and so fourth until one way or another the exception is handled.

What I was wondering is does execution continue in the method that caused the error or does execution continue in the method that handles the error.

Any basic examples would be great.

Even thought it's an old post, has anyone got an idea why not using the following concept:

Creating/opening a file with share mode of FILE_SHARE_WRITE.
Having a named global mutex, and opening it.
Whenever a file write is desired, lock the mutex first, then write to the file.

Any input?

NOTE: My previous answer was wrong. It has now been corrected.

C/C++ do not implement anything like Call-By-Value-Result (natively). As I understand it, that's an ADA term (Working on government code?). Call-By-Value would result in 15, Call-By-Reference is the trickiest one, because you would be modifying a in line 3 as well as line 4 of your example.

--EDIT--

I have implemented the following code, which I believe to be a valid representation of the syntax described (I'm not familiar enough with ADA to do the test directly, maybe someone else can). As you will see, the result for By-Value-Result is 15.

#include <iostream> int a_v, a_r, a_vr; void foo_by_val(int x) { x = x + 10; a_v = a_v + x; } void foo_by_ref(int &x) { x = x + 10; a_r = a_r + x; } void foo_by_value_result(int &x_ref) { int x = x_ref; x = x + 10; a_vr = a_vr + x; // x = x_ref; <-- My previous mistake x_ref = x; } void fie( ){ a_v = 5; a_r = 5; a_vr = 5; foo_by_val(a_v); foo_by_ref(a_r); foo_by_value_result(a_vr); std::cout << "By Value: " << a_v << std::endl; std::cout << "By Refference: " << a_r << std::endl; std::cout << "By Value Result: " << a_vr << std::endl; } int main() { fie(); return 0; }

Result:

By Value: 20 By Reference: 30 By Value Result: 15

I think you should shorten your code like this http://jsfiddle.net/DreamBig/tA7qw/4/. I put backgound-image in the div so you don't have to write it again in the keyframes definition like 6 or 10 times.

background-image: url('http://www.rotateweb.com/images/WebDesignB1.jpg');

I've tested and it runs perfectly in FF.

Array indices start from 0 and are upto [upperbound-1]. Since your loop starts at 0, it must end at < the limit value rather than <= limit value. So, change the "<=" to "<" in the loop. Eg:

col <= _maxColIndex

should be changed to

col < _maxColIndex

I suspect that inside the script, your working directory is elsewhere, thus you cannot cd. Try this: instead of

cd "$DIREC"

replace it with

echo current directory is $PWD cd "m25.1240_m22.1250_m5.1540"

and see if you still have the same problem.

Also, try getting rid of all of the http module, as express handles most of that for you. Look at the beginning Hello World for Express, http://expressjs.com/starter/hello-world.html and look for the part where it handles the port.

You have multiple problems here:

r simply means treat the string as a raw string, it looks like you might think it creates a regular expression object; (in any case, zip.extract() only accepts strings)
The * quantifier at the start of the regex has no character before it to match

You need to manually iterate through the zip file index and match the filenames against your regex:

from zipfile import ZipFile import re zip = ZipFile('myzipfile.zip') for info in zip.infolist(): if re.match(r'.*test.*\.xlsx$', info.filename): print info.filename zip.extract(info)

You might also consider using shell file globbing syntax: fnmatchcase(info.filename, '*.test.*.xls') (behind the scenes it converts it to a regex but it makes your code slightly simpler)

14665748 0 Differences between p-values in summary and from the anova in R lm()

I am seeing differences in the p-value for the anova depending on how I access this.

Is there a way to get the same value that is returned by the summary?

One easy to represent case returns < 2.2e-16 in the summary and in the anova but gives me 8.129959e-100 when I access the value directly:

x <- lm(formula = eruptions ~ waiting, data = faithful) summary(x) anova(x) anova(x)$"Pr(>F)"[1]

In another more difficult to represent case (there is a lot more data) I get p-value: < 2.2e-16 in the summary but 0 from anova.

Is there any way to get the actual value that is returned in the summary and anova?

I really appreciate your help -

Your fetch XML looks correct to me. When you set up the subgrid did you set "Records" = "All Record Types" in the Data Source section? If you did not then the subgrid will append a condition to your fetchxml so that it returns only records related to the specific relationship that you specified.

You can do this:

[Flags] enum Options { Option1 = 1, Option2 = 2, Option3 = 4, Option4 = 8, AllOptions = Option1 | Option2 | Option3 | Option4 }

This approach literally means Option1 and Option2 and Option3 and Option4. You can use this as:

Options.AllOptions;

Options.Option1 | Options.Option2 | Options.Option3 | Option.Option4

Both of the above will end up as the same result.

If you want to create instance of your class from name = Paul AND age = 16 AND country = china that kind of script, then you could create yourself method

public <T> T builder(Class<T> clazz, String line) throws InstantiationException, IllegalAccessException, SecurityException, NoSuchMethodException, IllegalArgumentException, InvocationTargetException { T instance = clazz.newInstance(); String[] exps = line.split("AND"); for (String exp : exps) { String[] tokens = exp.split("=", 2); // TODO check if token has length==2 tokens[0] = tokens[0].trim(); tokens[1] = tokens[1].trim(); String methodName = "set" + (("" + tokens[0].charAt(0)).toUpperCase()) + tokens[0].substring(1); Method m1 = instance.getClass().getMethod(methodName, String.class); m1.invoke(instance, tokens[1]); } return instance; }

and when you call it builder(Person.class,"name = Paul AND age = 16 AND country = china") you will get instance of Person class with populated fields name, age and country.

Is that what you are looking for?

Its becasue,Java CLASSPATH points to current directory denoted by "." and it will look for classes in the current directory.

In case we have multiple directories defined in CLASSPATH variable, Java will look for a class starting from the first directory and only look the second directory in case it did not find the specified class in the first directory. Multiple directories are added in classpath with the help of ":"

you have set classpath like

javac -classpath .:/path/to/graph/*:/path/to/graph/lib/* ErrorTest*.java

so using this command you are setting multiple directories in classpath.

JVM search directory in the order they have listed in CLASSPATH variable.

In your case seems some classes are present in the current directory so if you are not providing current directory in classpath JVM searches in second path and then third but required class is not present so seems that it is not working

28126915 0 select data from 3 tables in laravel by using Eloquent ORM

I am new to laravel and stuck on getting data using Eloquent ORM.

My Scenario is I have 3 tables

user - Contains user info
location - Contains Location info
location_user - Contains user id , location id , time when the user visited that location.

Now a user can visit a location multiple times and a location can be visited by multiple users.

I want to get all location name that a user visited on particular date.

But unable to get.

Below is the db structure

location_user table - id user_id location_id visitedtime

location table - id latitude longitude locality

user table - id name phone email

and In user model I have defined the relation

public function locations() { return $this->belongsToMany('Location')->withPivot('visitedtime'); }

when i use this function in controller then i get all the locations visited by that user

User::find(2)->locations()->select('locations.locality',locations.id')->get()

How can put condition on visitedtime on the above function

I'm getting confused of seeing other's Answer. Then I searched a lot and get some idea about that. While searching only, I have learnt about new concept of A-GPS. I would like to share those things with you.

There are three location providers.

1. GPS Provider 2. Network Provider (AGPS, CellID, WiFi MACID) 3. Passive Provider.

Note: I refer this from this site. As you asked question related to network provider, I will share regarding to that.

Network provider, name itself says that it needs network connection. Refer this article. It need network or WIFI connection to proceed.

A-GPS

GPS on cell phones is a bit more murky. In general, it won't cost you anything to turn on the GPS in your cell phone, but when you get a location it usually involves the cell phone company in order to get it quickly with little signal, as well as get a location when the satellites aren't visible (since the gov't requires a fix even if the satellites aren't visible for emergency 911 purposes). It uses up some cellular bandwidth. This also means that for phones without a regular GPS receiver, you cannot use the GPS at all if you don't have cell phone service.

For this reason most cell phone companies have the GPS in the phone turned off except for emergency calls and for services they sell you (such as directions).

This particular kind of GPS is called Assisted GPS (AGPS).

Note: Even if phone supports it, and network does not then this does not work

17243437 0 Media Foundation: How to Decode Compressed AVI?

folks!

I'm trying to transcode a compressed .avi file to .wmv using Media Foundation. While I've succeeded in using MSDN's sample for transcoding to handle an uncompressed .avi, I've had no luck with several different types of compressed .avi (Windows Video 1 is one example of compression).

Does anyone have experience with this? I have had little luck searching, other than MSDN (which does not clearly handle this particular case).

One route I'm leaning toward is writing a custom Media Foundation Transform to decode using Video For Windows internally, but it seems like I -must- be reinventing the wheel. A sample of something similar can be found here.

Please tell me I'm foolish and show me what I'm missing! Thanks. :)

how the code would be written greatly depends on where this array of 2 letter strings you have is coming from...but here is a self-contained example with some randomly generated 2 letter strings:

$strings = range('A','Z'); for ($a = 0;$a < 100; $a++) { $array[] = $strings[rand(0,25)] . $strings[rand(0,25)]; } for ($table = 1; $table <= 4; $table++) { $count = 0; $tarray = $array; echo "table " . $table . "<br/>"; echo "<table border='1'>"; for ($x = 0; $x < 10; $x++) { echo "<tr>"; for ($y = 0; $y < 10; $y++) { $alpha = array_splice($tarray,rand(0,count($tarray)-1),1); echo "<td>" . $count . $alpha[0] . "</td>"; $count++; } echo "</tr>"; } echo "</table>"; }

could shorten this with completely random generated 2 letter strings but i particularly wanted to show use of array_splice() if you have an actual array of 100 (or 400?) 2 letter strings and wanted to do a "pick once" deal, where you randomly select it and can only use it on one cell.

13031542 0 algorithms to emulate human movement in a stick figure

I need to make a program that lets you animate a stick figure, so I'm looking for some information on algorithms to emulate human movement. I found some software that lets you create animations with stick figures, but are hard to use because basically they don't help you emulate realistic movement, so the animator is responsible for everything. That's cool when you are or have an animator, but I'm not, I'm only a programmer.

I would really appreciate if someone knows about a library, or text with an explanation of these kinds of algorithms.

During the search for an answer i found many people with the same issue. I figured it out myself so here is my solution. I hope it is useful for other people.

Step 1. Create a SplitViewController project. If you have a project already skip this step ;) enter image description here

Step 2. Add two different viewControllers. In this case i call them AbcViewController and XyzViewController. enter image description here

Step 3. Go to the ipad storyboard, remove the DetailViewController from the storyboard. Then add two new viewControllers.

enter image description here

Step 4. Set the class and the Storyboard ID for your viewControllers. enter image description here

Step 5. Go to your MasterViewController.h and replace the code with the code below.

#import <UIKit/UIKit.h> @class AbcViewController; @class XyzViewController; @interface MasterViewController : UITableViewController @property (strong, nonatomic) AbcViewController *abcViewController; @property (strong, nonatomic) XyzViewController *xyzViewController; @end

Step 6. Now go to your MasterViewController.m file and replace with this code:

Note: If you have an existing project and don't want to replace use the code in step 7.

#import "MasterViewController.h" #import "DetailViewController.h" @interface MasterViewController () { NSMutableArray *_objects; } @end @implementation MasterViewController - (void)awakeFromNib { if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) { self.clearsSelectionOnViewWillAppear = NO; self.preferredContentSize = CGSizeMake(320.0, 600.0); } [super awakeFromNib]; } - (void)viewDidLoad { [super viewDidLoad]; self.detailViewController = (DetailViewController*)[[self.splitViewController.viewControllers lastObject] topViewController]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } #pragma mark - Table View - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 2; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath]; if (indexPath.row == 0) { cell.textLabel.text = @"ABC"; } if (indexPath.row == 1) { cell.textLabel.text = @"XYZ"; } return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { self.abcViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"ABC"]; self.xyzViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"XYZ"]; if (indexPath.row == 0) { NSArray *newVCs = [NSArray arrayWithObjects:[[[self splitViewController ] viewControllers ] firstObject ] , self.abcViewController, nil]; self.splitViewController.viewControllers = newVCs; } if (indexPath.row == 1) { NSArray *newVCs = [NSArray arrayWithObjects:[[[self splitViewController ] viewControllers ] firstObject ] , self.xyzViewController, nil]; self.splitViewController.viewControllers = newVCs; } } @end

Step 7.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { self.abcViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"ABC"]; self.xyzViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"XYZ"]; if (indexPath.row == 0) { NSArray *newVCs = [NSArray arrayWithObjects:[[[self splitViewController ] viewControllers ] firstObject ] , self.abcViewController, nil]; self.splitViewController.viewControllers = newVCs; } if (indexPath.row == 1) { NSArray *newVCs = [NSArray arrayWithObjects:[[[self splitViewController ] viewControllers ] firstObject ] , self.xyzViewController, nil]; self.splitViewController.viewControllers = newVCs; } }

Thats it, run your project and enjoy :)

If you can specify what kinds of search strings this method will accept, you can use regular expressions. Here's an example which also uses Linq for brevity:

public IList<String> GetMatchingRemoteFiles(String SearchPattern, bool ignoreCase) { var options = ignoreCase ? RegexOptions.IgnoreCase : RegexOptions.None; return thirdPartyTool.ftpClient.GetCurrentDirectoryContents() .Where(fn => Regex.Matches(fn, SearchPattern, options)) .ToList(); }

Even if you cannot control what kinds of search strings this method accepts, it's still probably easier to convert the search string to a regular expression than write your own algorithm for matching the patterns. See Bobson's answer for details on how to do this.

TCP has no concept of packets. A TCP stream is a continuous stream of bytes - if you want a structure within that stream of bytes, you have to impose it yourself, by implementing some kind of framing mechanism. A simple one is the "length prefix" - when sending an application-level frame, you first send the length of the frame, then the data.

20959054 0 Why is there a dramatic difference between aov and lmer?

I have a mixed model and the data looks like this:

> head(pce.ddply) subject Condition errorType errors 1 j202 G O 0.00000000 2 j202 G P 0.00000000 3 j203 G O 0.08333333 4 j203 G P 0.00000000 5 j205 G O 0.16666667 6 j205 G P 0.00000000

Each subject provides two datapoints for errorType (O or P) and each subject is in either Condition G (N=30) or N (N=33). errorType is a repeated variable and Condition is a between variable. I'm interested in both main effects and the interactions. So, first an anova:

> summary(aov(errors ~ Condition * errorType + Error(subject/(errorType)), data = pce.ddply)) Error: subject Df Sum Sq Mean Sq F value Pr(>F) Condition 1 0.00507 0.005065 2.465 0.122 Residuals 61 0.12534 0.002055 Error: subject:errorType Df Sum Sq Mean Sq F value Pr(>F) errorType 1 0.03199 0.03199 10.52 0.001919 ** Condition:errorType 1 0.04010 0.04010 13.19 0.000579 *** Residuals 61 0.18552 0.00304

Condition is not significant, but errorType is, as well as the interaction.

However, when I use lmer, I get a totally different set of results:

> lmer(errors ~ Condition * errorType + (1 | subject), data = pce.ddply) Linear mixed model fit by REML Formula: errors ~ Condition * errorType + (1 | subject) Data: pce.ddply AIC BIC logLik deviance REMLdev -356.6 -339.6 184.3 -399 -368.6 Random effects: Groups Name Variance Std.Dev. subject (Intercept) 0.000000 0.000000 Residual 0.002548 0.050477 Number of obs: 126, groups: subject, 63 Fixed effects: Estimate Std.

So for lmer, Condition and the interaction are significant, but errorType is not.

Also, the lmer result is exactly the same as a glm result, leading me to believe something is wrong.

Can someone please help me understand why they are so different? I suspect I am using lmer incorrectly (though I've tried many other versions like (errorType | subject) with similar results.

You don't want to change an include. That's not an option.

It seems that you want to use AJAX. You could load the content of the include in any element of the site using $.load.

For example. To load link1.php in the element #links, we could do:

$(document).ready(function() { $('.allbuttons #button1').click(function() { $('#links').load("http://"+ document.domain + "/includes/link1.php"); }); $('.allbuttons #button2').click(function() { $('#links').load("http://"+ document.domain + "/includes/link2.php"); }); });

35901004 0 Failing to deliver Azure NotificationHub push messages to (Android) devices from .NET console app

I have configured a .NET App Service using the "Quick Start" instructions in the newer Azure Portal to publish an app service to use as my mobile back end. I have also configured a notification hub for it and am able to send push notifications from a Xamarin.Forms Android app via the Azure mobile back end endpoint. I can also receive the push notification on a registered Android device.

I need to be able to send push notifications to registered devices from a C# console application but no matter what I try, the push messages are not delivered.

I am using the following code to attempt to send push messages. When I run it, the execution ends on...

 var result = await hub.SendTemplateNotificationAsync(templateParams);

...and console app terminates without waiting for the response and the push notification is never delivered to the registered device.

public async void PushSmartAlerts() { string notificationHubName = "DevXXXXNotificationHub"; string notificationHubConnection = "Endpoint=sb://devXXXXXnotificationhubnamespace.servicebus.windows.net/;SharedAccessKeyName=DefaultFullSharedAccessSignature;SharedAccessKey=SnXXXXXXXXXXXXXXXXXXXXXXXX9N8="; hub = NotificationHubClient .CreateClientFromConnectionString(notificationHubConnection, notificationHubName); Dictionary<string, string> templateParams = new Dictionary<string, string>(); templateParams["messageParam"] = "Hello"; var result = await hub.SendTemplateNotificationAsync(templateParams); }

Can anyone tell me what is wrong or if I am going about it the wrong way?

Nope, not possible, at least not for class constants.

You cannot use any of the following [reserved] words as constants, class names, function or method names.

I don't know about C#, but there isn't any special symbol in PHP to transform a keyword into an identifier. As long as you don't name it exactly the same as a keyword (barring letter case), it'll just be any normal constant name.

How about a (different since it's not just CSS) prefix? Gets repetitive to type, but is a nice workaround. I realize this may be redundant as well if your class is named something like HTMLAttribute, but it's the easiest way out.

const A_ID = 'id'; const A_CLASS = 'class'; // etc

DO NOT use htmlUnit.

You would've thought that you would only need a couple of core jars. Nah, you might need all of them otherwise you might run into some class not found errors.

Just take a look at how many jars you have to load into Eclipse before you can run it! A total of 21 jars, over 10mb! Bear in mind that you can also package up to 50mb for Android Market. It just slows Eclipse down and you probably have to increase the memory when you debug.

Use Jsoup instead!

40597026 0 regex character appears exactly x times

I'm working in bash and I have a large file in which I want to remove all the lines that do not match a certain regex, probably using $ grep -e "<regex>" <file> > output.txt

What I want to keep is any line that contain exactly x times a specified character, for example in the binary sequence

0000, 0001, 0010, 0011, 0100, 0101, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111

I would like to keep only those who have 2 1, leaving me with

0011, 0101, 0110, 1001, 1010, 1100

I would then use a bash variable to vary the amount I need (always exactly half of the length, working with strings of the same length) I'm litterally looking for lines that are half 0 and half 1

I have this right now. It's not using regex. It works, but is very slow:

($1 is the length of every string, $d is just a directory)

sed -e 's/\(.\)/\1 /g' < $d/input.txt > $d/spaces.txt awk '{c=0;for(i=1;i<=NF;++i){c+=$i};print c}' $d/spaces.txt > $d/sums.txt grep -n "$(($1/2))" $d/sums.txt | cut -f1 -d: > $d/linenums.txt for i in $(cat $d/linenums.txt) do sed "${i}q;d" $d/input.txt done > $d/valids.txt

In case you wonder this puts spaces in between every digit turning 1010 into 1 0 1 0, then it adds the values together, saves the results in sums.txt, grep for length/2 and save only the line numbers in linenums.txt, then it reads linenums.txt and outputs the corresponding line from input.txt to output.txt

I need something quicker, the for loop is what's taking way too long

Thanks for your time and for sharing your knowledge with me.

zerkms's answer cuts to the gist of what you actually need to know, and is correct. Transaction isolation will make sure you're not affected by concurrency issues in this simple case (but note, it's not a magic solution to all concurrency).

To answer your question literally as written: they're actually interleaved.

If you write:

SELECT SUM(field1)+SUM(field2)+SUM(field3)-SUM(field4) FROM mytable;

then Pg reads mytable once. It reads each row and feeds the mytable.field1 to the first sum, mytable.field2 into the second sum, etc. Then it repeats for each row.

So all the aggregation is done in parallel (though not using multiple CPUs).

39514294 0 C# Interop.Outlook: Folder.AddToPFFavorites() without adding all subfolders?

In Outlook, I'm trying to add a shared public folder (provided by Exchange) to the list of favorite folders programmatically. I've written an Outlook-AddIn for this, that uses the Microsoft.Office.Interop.Outlook library. In this library, there's only one way to add public folders to the favorite list:

Folder.AddToPFFavorites().

The problem: When calling this method, Outlook not only adds the folder itself to the favorites list, but also ALL subfolders. In our company, we have a huge tree of subfolders attached to some folders, so I get major performance problems (Outlook completely crashes when the folder to add has too many subfolders).

Do you know a way to programmatically add only the folder itself to the favorites, without any subfolders?

From the error log i.e. MediaPlayer Event 11 was not found in the queue, already cancelled is a warning and not an error. Please refer to this link. Hence, if your MediaPlayer is exiting, then there should be some other issue.

This warning is printed when an event which was expected to be triggered gets removed from the queue before it actually triggered. This can happen in multiple cases. For example, in case of pause, all player events are cancelled as shown here.

In your case, I feel that one of the potential scenario would be thus. AwesomePlayer would have triggered an event to read the next video frame from the video decoder i.e. mVideoSource. In between you pressed pause which caused all events to be removed. So when TimedEventQueue triggered in this threadRun loop, it would observe that this event has been removed and hence, the log.

As the OP mentioned that both player play the game optimally,I am going to present an algorithm under this assumption.

Definitely if both players play optimally,then definitely the sum they obtain at the end would be maximum,otherwise they are not playing optimally.

There are two different cases here:

I make the first move and pick element at position x

Now because we have to obey the condition that only adjacent elements could be picked,let me define two arrays here.

left[x]: It is the sum of elements that can be obtained by adding

array[0],array[1]....array[x-1],the elements left to x.

right[x]: It is the sum of elements that can be obtained by adding

array[x+1],array[x+2]....array[n-1],the elements right to x.

Now,because the other player also plays optimally,what he will do is he will check what I can possibly achieve and he finds that,I could achieve the following:

array[x] + left[x] = S1

array[x] + right[x] = S2

So what the other player does is finds the minimum of the S1 and S2.

If S1 < S2 this means that if the other player picks element at x+1,he just took away the better part of array from us because now we are left with a lesser sum S1

If S1 > S2 this means that if the other player picks element at x-1,he just took away the better part of array from us because now we are left with a lesser sum S2

Because I am also playing optimally I would in the very first move pick such x which has minimum absolute value of (right[x]-left[x]),so that even if our opponent takes the better part of array from us,he is only able to take away minimum

Therefore,If both players play optimally, the maximum sums obtained are:

Update.

x + left[x] and right[x]//when second player in his first move picks x+1

Therefore,in this case the moves made are:

Player 1:Picks element at position x,x-1,x-2....0. Player 2:Picks element at position x+1,x+2,....n-1

Because each player has to pick adjacent element to the previously picked element by him.

x + right[x] and left[x]//when second player in his first move picks x-1

Therefore,in this case the moves made are:

Player 1:Picks element at position x,x+1,x+2....n-1. Player 2:Picks element at position x-1,x-2,....0.

Because each player has to pick adjacent element to the previously picked element by him.

where x is such that we obtain minimum absolute value of (right[x]-left[x]).

Since OP insisted on posting pseudocode,here is one:

Computing the left and right array.

for(i = 0 to n-1) { if(i==0) left[i]=0; else left[i] = left[i] + array[i-1]; j = n-1-i; if(j==n-1) right[j]=0; else right[j]= right[j] + array[j+1]; }

The left and right arrays initially have 0 in all positions.

Computing max_sums.

Find_the_max_sums() { min = absoulte_value_of(right[0]-left[0]) x = 0; for(i = 1 to n-1) { if( absolute_value_of(right[i]-left[i]) < min) { min = absolute_value_of(right[i]-left[i]); x=i; } } }

Clearly Both space and time complexity of this algorithm is linear.

40063205 1 pdfkit - python : 'str' object has no attribute decode

I am attempting to use pdfkit to convert string html to a pdf file. This is what I am doing

 try: options = { 'page-size': 'A4', 'margin-top': '0.75in', 'margin-right': '0.75in', 'margin-bottom': '0.75in', 'margin-left': '0.75in', } config = pdfkit.configuration(wkhtmltopdf="/usr/local/bin/wkhtmltopdf") str= "Hello!!" pdfkit.from_string(str,"Somefile.pdf",options=options,configuration=config) return HttpResponse("Works") except Exception as e: return HttpResponse(str(e))

however at from_string I get the exception 'str' object has no attribute decode. Any suggestions on how I can fix this ? I am using Python 3.5.1

I'm new with WTForms but it seems to me that the solution could be improved instead of using :

{{ form.field(autofocus=true, required=true, placeholder="foo") }}

use :

{% if field.flags.required %} {{ field(autofocus=true, required=field.flags.required, placeholder="foo") }} {% else %} {{ field(autofocus=true, placeholder="foo") }} {% endif %}

WTForms seems not to handle correctly required=false for 100% HTML5 and sets in the HTML an attr required="False" instead of removing the attr. Could this be improved in next version of WTForms?

36443204 0 Using auto layout at the expense of having no frame

I have a box that is initiated without a frame so it has 0 center and size.

let blackBox = UIView() blackBox.backgroundColor = .blackColor() blackBox.translatesAutoresizingMaskIntoConstraints = false view.addSubview(blackBox) view.addConstraint(NSLayoutConstraint(item: blackBox, attribute: .Width, relatedBy: .Equal, toItem: view, attribute: .Width, multiplier: 0.1, constant: 0)) view.addConstraint(NSLayoutConstraint(item: blackBox, attribute: .Height, relatedBy: .Equal, toItem: view, attribute: .Height, multiplier: 0.5, constant: 0)) view.addConstraint(NSLayoutConstraint(item: blackBox, attribute: .CenterX, relatedBy: .Equal, toItem: view, attribute: .CenterX, multiplier: 1, constant: 0)) view.addConstraint(NSLayoutConstraint(item: blackBox, attribute: .CenterY, relatedBy: .Equal, toItem: view, attribute: .CenterY, multiplier: 1, constant: 0))

Is there anyway to insert a centered subview into the blackBox without using autolayout or is there a neater way I could/should use it. The only way I can see this happening is:

let blueBox = UIView() blackBox.addSubview(blueBox) blueBox.translatesAutoresizingMaskIntoConstraints = false blueBox.backgroundColor = UIColor.blueColor() view.addConstraint(NSLayoutConstraint(item: blueBox, attribute: .CenterX, relatedBy: .Equal, toItem: blackBox, attribute: .CenterX, multiplier: 1, constant: 0)) view.addConstraint(NSLayoutConstraint(item: blueBox, attribute: .CenterY, relatedBy: .Equal, toItem: blackBox, attribute: .CenterY, multiplier: 1, constant: 0)) view.addConstraint(NSLayoutConstraint(item: blueBox, attribute: .Width, relatedBy: .Equal, toItem: blackBox, attribute: .Width, multiplier: 0.4, constant: 0)) view.addConstraint(NSLayoutConstraint(item: blueBox, attribute: .Height, relatedBy: .Equal, toItem: blackBox, attribute: .Height, multiplier: 0.4, constant: 0))

I know I'm coming really late to the game, but we were struggling with this exact same problem and here is how we solved it.

First, we edited the csproj files of all non-merged or satellite projects to use a conditional reference to an external assembly based upon existence of a file. In this case, we're going to test for the existence of the merged assembly. Then we ran a build script which does the following:

Builds the solution.
Runs ILMerge on your primary assemblies with the output being the file in the conditional reference.
Rebuild the solution, but this time because the merged assembly exists, the non-merged or satellite assemblies will now have the correct reference.

20365954 0 Entity Framework: DefiningQuery error

I have a Junction table with clustered index

CREATE TABLE [dbo].[MeetingTags] ( [MeetingId] INT NOT NULL, [TagId] INT NOT NULL, CONSTRAINT [FK_MeetingTags_Tags] FOREIGN KEY ([MeetingId]) REFERENCES [dbo].[Meetings] ([Id]), CONSTRAINT [FK_Tags_MeetingTags] FOREIGN KEY ([TagId]) REFERENCES [dbo].[Tags] ([Id]) ); GO CREATE CLUSTERED INDEX [cdxMeetingTags] ON [dbo].[MeetingTags]([MeetingId] ASC, [TagId] ASC);

Obviously, it has common field of the table Meetings and Tags so that I can add record on it by this way

var tag= new Tag() { Title = "Meeting Title", }; meeting.Tags.Add(tag);

Looks good, however I'm getting this error in Context.SaveChanges() when Inserting new Tags record.

Unable to update the EntitySet 'MeetingTags' because it has a DefiningQuery and no <InsertFunction> element exists in the <ModificationFunctionMapping> element to support the current operation

Tags has Primary Key.

I think putting a Primary Key in the MeetingTags is not possible as it will break the Many-to-Many relationship of Meeting and Tags in the EF, and it will also add Meeting.MeetingTags.Tags in the syntax instead of just Meeting.Tags

Any workaround on this?

function getWordAt(str, pos) { // Perform type conversions. str = String(str); pos = Number(pos) >>> 0; // Search for the word's beginning and end. var left = str.slice(0, pos + 1).search(/\S+$/), right = str.slice(pos).search(/\s/); // The last word in the string is a special case. if (right < 0) { return str.slice(left); } // Return the word, using the located bounds to extract it from the string. return str.slice(left, right + pos); }

This function accepts any whitespace character as a word separator, including spaces, tabs, and newlines. Essentially, it looks:

For the beginning of the word, matched by /\S+$/
Just past the end of the word, using /\s/

As written, the function will return "" if the index of a whitespace character is given; spaces are not part of words themselves. If you want the function to instead return the preceding word, change /\S+$/ to /\S+\s*/.

Here is some example output for "This is a sentence."

0: This 1: This 2: This 3: This 4: 5: is 6: is 7: 8: a 9: 10: sentence. // ... 18: sentence.

Modified to return the preceding word, the output becomes:

0: This 1: This 2: This 3: This 4: This 5: is 6: is 7: is 8: a 9: a 10: sentence. // ... 18: sentence.

Chrome ignores prefer-online or at least it used to. Firefox honors it, or at least it used to. So test it with Firefox.

Generally, do not rely on prefer-online as the user agent can choose to ignore it. Think of it more as advisory than compulsory.

But Haskell doesn't seem to be too happy with:
thecolour:leftofcurrent:rightofcurrent 

That's because leftofcurrent is a List. If you want to combine those lists, it needs to be:

(thecolour:leftofcurrent) ++ rightofcurrent

Likewise, (leftofcurrent:current:[]) is impossible because leftofcurrent is a List, but this is probably what you're after:

leftofcurrent ++ [current]

The cons operator : expects a single element on the left and a list on the right. But because of its fixity, you can chain them together so that a bunch of single items are separated by : and ended with a list. That is,

item1:item2:item3:[] -- is the same as item1:(item2:(item3:[]))

Also, your pattern matching is non-exhaustive. You need to handle the case where the second list parameter is empty.

putfront leftofcurrent [] thecolour = ...

Not really doable without CSS. The easiest way to handle a scenario is to wrap the three divs in a container, then use display: inline-block on the three divs.

29070988 0 Server doesn't display a right content in browsers after wordpress installed as a toturial

At the beginning of the new year, I buy a domain: danielpan.me. After creating a droplet in digitalocean, I deployed wordpress on my remote server. The tutorial I followed is here. But something I didn't understand happened. After removing the file of /var/www/html/index.html, my server displayed like this:

Wrong isplaying after removing index.html

You know, this is not a right result. It should display something like this:

Right display after removing index.html

This confused me a lot. I don't know how to do next after that much googling. Even so I don't want a solution about redirections. Could anyone who ever run into such a scene help me? Thanks very much in advance.

Download Web Matrix from

http://www.microsoft.com/web/webmatrix/

Choose 'site from web gallery' I believe there are a whole bunch in there. Once you download those and configure you can simply open the same solution in visual studio. This one uses a template to do it - you want 'gallery' instead- but the screen shots here show you how basic it is to get web matrix up and the initial screens you want:

There is no significant difference between these, you will get pretty much the same results:

 str.Split(';').First() vs. str.Split(';')[0]

For your second comparison, here you are asking only the first element

list.Where(x => x > 1).First()

So as soon as WhereIterator returns an item it's done. But in second you are putting all results into list then getting the first item using indexer , therefore it will be slower.

First of all - in your sql you have:

`product_id` = '1'

do not use id value as a string:

`product_id` = 1

About your problem:

Add another condition:

if ('POST' == $_SERVER['REQUEST_METHOD']) { if ( !empty($_POST['submitType']) && ( $_POST['submitType'] == 'like' ) ) { $sql = "UPDATE table set `likes` = `likes`+1 where `product_id` = '1'"; $result=mysql_query($sql); } }

and in html:

<input type = "submit" name="submitType" value = "like"/>

You Should use Cookie not Set-Cokkie. Others are fine

req = urllib2.Request(url) req.add_header('Content-Type', 'application/json') req.add_header('Cookie', 'session=value=') response = urllib2.urlopen(req, data=json.dump(data))

When Server response, it uses Set-Cookie to persist a cookie in client, when client want to callback, it just use Cookie as header.

The reason this doesn't work is because the deprecated Date constructor that you're using expects year - 1900 as the first argument.

You should either use a SimpleDateFormat or a GregorianCalendar to do this conversion instead. Since there is already an excellent answer here, showing the use of SimpleDateFormat, here's how you use GregorianCalendar for 1:39am on 14 March 2014.

new GregorianCalendar(2014, 2, 14, 1, 39, 0).getTime().getTime();

Beware that the month uses 0 for January and 11 for December.

To position something absolutely (which is what you want to do), it has to have container that also has positioning set to position itself against. Sounds complex, but it's not really.

If you set your container to position:relative (meaning keep it in the flow of the document where it would normally be), then you can set descendant elements to position: absolute.

So, in your case, if you wrap your image and button in a div and set the div to position: relative, you can set the button to position: absolute like this:

<div style="position: relative;"> <img src="yourimagename.jpg" alt=""> <button style="position: absolute; top: 0; right: 0; z-index: 1;">&times</button> </div

I agree with JDillon's answer to set the data-src and then switch the src when ready to init the player. Like so:

html

<iframe id="sc-widget" width="0" height="0" scrolling="no" frameborder="no" src="" data-src="https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/3333333%3Fsecret_token%3Dx-xxxx&amp;auto_play=false&amp;hide_related=false&amp;show_comments=true&amp;show_user=true&amp;show_reposts=false&amp;visual=true"></iframe>

js (es6)

let widgetIframe = document.getElementById('sc-widget') widgetIframe.src = widgetIframe.dataset.src let $embedPlayer = SC.Widget(widgetIframe) /* example of using soundcloud embed player */ $embedPlayer.bind(SC.Widget.Events.PLAY, () => { $embedPlayer.getDuration((duration) => setDuration(duration)) }) $embedPlayer.bind(SC.Widget.Events.PLAY_PROGRESS, () => { $embedPlayer.getPosition((position) => setPosition(position)) }) function setPosition(pos) { console.log(pos) } function setDuration(dur) { console.log(dur) }

Then I also agree with adi's answer that you cannot use display: none; to hide the player if you are creating your own player to control the soundcloud embed player. In this case you need to hide it with the following styles:

css

iframe { max-width: 10rem; opacity: 0; position: absolute; visibility: hidden; }

i will try to generate the primary keys using table generator. but when i insert the 6 records in my table, the primaryKey table show only one on value. here is the following code

My Entity class

package com.generatorvaluetest.domain; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.SequenceGenerator; import javax.persistence.TableGenerator; @Entity public class Snufu { private int autoId; private int identityId; private int sequenceId; private int tableId; private String name; public int getAutoId() { return autoId; } public void setAutoId(int autoId) { this.autoId = autoId; } public int getIdentityId() { return identityId; } public void setIdentityId(int identityId) { this.identityId = identityId; } public int getSequenceId() { return sequenceId; } public void setSequenceId(int sequenceId) { this.sequenceId = sequenceId; } @Id @TableGenerator(name="tg" , table="pk_table", pkColumnName="name" , valueColumnName="vlaue" , allocationSize=10) @GeneratedValue(strategy=GenerationType.TABLE , generator="tg") public int getTableId() { return tableId; } public void setTableId(int tableId) { this.tableId = tableId; } public String getName() { return name; } public void setName(String name) { this.name = name; } }

This is my main class

 package com.generatorvaluetest.main; import org.hibernate.HibernateException; import org.hibernate.Session; import com.generatorvaluetest.domain.Snufu; import com.generatorvaluetest.util.HibernateUtil; public class GeneratorValueTest { public static void main(String[] args) throws HibernateException{ HibernateUtil.recreateDatabase(); Session session = HibernateUtil.beginTransaction(); for(int i = 0 ; i< 5 ; i++){ Snufu snufu = new Snufu(); snufu.setName("jimmy"+i); session.saveOrUpdate(snufu); } new Thread(new Runnable() { @Override public void run() { Session session = HibernateUtil.beginTransaction(); Snufu snufu = new Snufu(); snufu.setName("jimmykalra"); session.saveOrUpdate(snufu); HibernateUtil.commitTransaction(); } }).start(); HibernateUtil.commitTransaction(); } }

in database when i select the values from pk_table the values are

|name | value| |snuf | 1 |

but in snufu tables there are 6 records

Did you take a look at the Go tutorial at http://golang.org/doc/go_tutorial.html

 Here's how to compile and run our program. With 6g, say, $ 6g helloworld.go # compile; object goes into helloworld.6 $ 6l helloworld.6 # link; output goes into 6.out $ 6.out Hello, world; or Καλημέρα κόσμε; or こんにちは 世界 $ With gccgo it looks a little more traditional. $ gccgo helloworld.go $ a.out Hello, world; or Καλημέρα κόσμε; or こんにちは 世界
