It is a different scenario .", "Question : Is there any way to target a column in a jqGrid in my case Struts2-jQuery-Grid Plugin 3.7.0 on certain rows only For example I want to show the content of the 2nd column only if the 1th column value is Movie : .. . .. . I ve tried to use conditional OGNL expressions in hidden and cssClass fields of the GridColumnTag http : code.google.com p struts2-jquery wiki GridColumnTag but immediately noticed they evaluate once against the whole column not at every iteration . As a workaround I can manually hide the columns in that rows with javascript after the grid is populated but that is a hack and I m wondering if there is a clean solution to conditionally do something on a columns per-row . NOTE : I can t simply erase the content from the source List as it would be obvious because COL 2 in my real case is a Boolean represented as checkbox . .. . Answer : There are many ways how you can implement the requirement . One of the most easy is the setting of color : transparent CSS on the cells which you need to hide . For example you define the CSS rule .. . .. . and you assign the class hiddenCell to specified cells of the COL 2 . You can use cellattr property of COL 2 for it : .. . .. . The demo http : www.ok-soft-gmbh.com jqGrid transparentTextInColumn.htm demonstrates the approach . Disadvantage of the approach - the hidden text still exist on HTML page and so one can examine it if required . Another way is the usage of custom formatters . For example you can define the following formatter callback .. . .. . The demo http : www.ok-soft-gmbh.com jqGrid removeTextInColumn.htm demonstrates the second approach . Disadvantage of the approach - it s a little difficult to combine usage of custom formatter with another formatter like formatter : select in the example above . Nevertheless one can do it too : .. . .. . like the next demo http : www.ok-soft-gmbh.com jqGrid removeTextInColumn .htm . If you loads the data from the server then probably the best choice would be to modify the input data the input data for the column COL 2 inside of beforeProcessing callback . See the answer http : stackoverflow.com a 9855764 315935 or this one http : stackoverflow.com a 9722466 315935 for code examples . Comment : Great answer . Regarding Solution 1 I don t think is possible in Struts2-jQuery-Grid it does not have cellattr exposed since I m using checkbox formatter I will create a custom one with another formatter as in Solution 2b . Thanks a lot . Comment : It worked like a charm . Two side effects checkbox is not centered in the td anymore and rows with even only one field empty returned from the formatter have an higher line-height 33 instead of 24 . Comment : Returning prevents the second one . Comment : @AndreaLigios : You are welcome I think that the usage of nbsp instead of or would be better .", "Question : null .. .

I have two classes where one is a MainWindow which holds all buttons sliders etc and a second class is a custom widget called drawingArea on which a user is able to draw . Basicly I ve implemented most of functions but unfortunetly I stucked at filling function which should work just like one in MS Paint . I decided to use so called floodFill algorithm and after few hours of fighting I am a beginner in Qt I have managed to make it work . But not at all . The problem is I am only able to fill black-colored regions shapes lines points etc with the color I choose . But when it comes to filling different colors it just puts one pixel in chosen color .

The really don t understand how it is working only on black color when passing argument QColor of different colors . I would really appreciate any help or ideas . .. . Answer : There is a fundamental problem with your code . Don t do the drawing from just any method called in your class . The drawing needs to be done in paint event callback that you define . QWidget : : paintEvent http : qt-project.org doc qt-4.8 qwidget.html paintEvent worth exploring . Other than that it is hard to say what else is wrong . BTW you can trigger drawing event by repaint or update .

Yes I can set the colour but I cannot change it as I would have expected . Could you help Thanks : D .. . Answer : The only way to change the color of a brush is via QBrush : : setColor . The brush takes a copy of the color you specify and not a reference . Maybe you are used to other programming-languages like Java where basically everything is a reference . In C++ there are values semantics https : akrzemi1.wordpress.com 2012 02 03 value-semantics . Comment : So should creating these brushes work : QBrush darkBrown QColor 83 71 65 QBrush clickedBrown QColor 122 83 66 Then this if-statement as a way of changing the colour rather than chnaging the colour of one brush but using two brushes and drawing with different brushes : if Pressed true painter- setBrush clickedBrown else painter- setBrush darkBrown because it doesn t either . Comment : Your if check is wrong since you always set Pressed to true Pressed true is an assignment . What you want is if Pressed true or simpler if Pressed .

Comment : It is a bad idea to do animations by modifying QSS . Because it s very slow . Comment : Fading one color into another works perfectly fine though . But if you have another approach in mind please feel free to share Always looking for better solutions . .. . Answer : The simplest way to do so would be to define a property for each stop : .. . .. . It s pretty ugly though . In your comment you mentioned that the RGB component of each colour is the same and the components were basically 249 181 214 and 249 . If you know that each colour is based off 249 you could do something like this : .. . .. . This allows you to use any colour for the color property so long as all components are the same and the other colours will scale automatically . As mentioned by @SaZ modifying stylesheets in this manner can be slow .

Under certain circumstances I wish to set it disabled . The widget has some color buttons that are set from a list of colors : .. . .. . Calling myWidget.setEnabled enabledOption disables the widget grays out all text and every other items in the widget - except for these color buttons . So I am thinking of making my own action : .. . .. . How can I make my buttons - of a background-color and text color that I don t know but the button does - have that disabled look Note - the color update works on disabled items too - that is not really complicated though - whatever style sheet I apply on setting widget disabled can be applied in the colorUpdate function . I just don t know how to apply a stylesheet with that gray shade - or possibly have a disabled option in the stylesheet even.. . .. . What do colors look like in disabled Comment : Just add the custom color change bindings to your setWidgetEnabled Easy way out is to to modify color balances for example hue and saturation . It s your custom data so you know best how it should look like when disabled . Comment : Thanks that is the biggest question I don t want the button to look custom different - just have the same washed out look as everything else . I don t know how to make colors look disabled . Comment : But you ve set custom colors to that button Why you d expect Qt to know how your colors should look when it s disabled Comment : Right - but I imagine disabled applies some sort of colorize or like you said a certain change in hue and saturation . I would like to know what that is . Comment : Well I d expect the rules to change between themes but setting custom styles explicitly overrides the defaults from the theme so you should figure out the disabled style you want too for your case . Decreasing saturation makes it look washed making the color darker or grayer makes it look disabled . Making fonts gray instead of whatever color may help too . I m not a designer so I can t tell you what your thing should do and SO anyway isn t Designer as a Service.. . .. . Answer : To set your own style for the disable state . You can set a special style for disabled state http : doc.qt.io qt-5 stylesheet-reference.html list-of-pseudo-states in the stylesheet : .. . .. . edit : changed code for the widget instead of a global stylesheet . .. . .. . .. . .. . To keep the default disabled style . You can set your custom style only for the enabled state then when the widget is disabled the style does not apply : Comment : The style MUST apply in disabled state . I just want it to looked washed-out as-if it was disabled . The first part of the answer I imagine I would need to subclass my button to do.. . And this still does not answer the question : How can I get disabled style colors based on existing colors and disabled style text even for black and white text . But I think I will use the comment to the question and decrease the color saturation . Comment : I misunderstood the question then . As said above best is probably to create your own disabled colors adapted to your custom colors . And to answer your comment no you don t need to subclass the button I gave a global QSS example but you can do this directly : m colorButton- setStyleSheet : enabled color : + foreground + background-color : + color + : disabled color : + disabledForeground + background-color : + disabledColor +", "Question : I have a simple problem but I can t solve it yet .

May be we can find better solution of your initial problem Comment : I have a QPushButton subclass when the button is long pressed I want to draw a circle with the inverse color of the background then inside it is a check symbol with the background-color . Another option for me is to erase some portion of the circle making that portion transparent to create a check mark .

Answer : It s very difficult if not impossible to find a way to get the backgound color of a button when it s pressed because it depends on the style and it s not guaranteed that the style respects the palette . However I suggest two different approaches : .. . .. . 1 . You can set you own background-color using style sheets simpler or implement the painting of the button yourself using styles or reimplementing paintEvent . See Customizing QPushButton http : doc.qt.io qt-5 stylesheet-examples.html customizing-qpushbutton .. . .. . 2 . To paint over the button with the inverse color you can set a composition mode to the painter in order to get the inverse color .

Has anyone else struggled with this .. . Answer : Yes I have been struggling with this after I add View controller-based status bar appearance in target s plist file it is working again on iOS 8 remember to set it to NO . In MasterViewController add this to avoid wrong background-image when detailViewController is dismissed . It basically set the same appearance again . Comment : +1 . This almost solves the problem if you are willing to give up on the view controller-based status bar appearance . Now when the Detail view controller is rotated the right navigation bar background-image is displayed . However when the Detail view controller is dismissed after at least one rotation the Master view controller displays the wrong navigation bar background-image until the interface is rotated again . Does the same happen to you Comment : Yes It happened to me too please see the edit . Comment : Thanks for sharing your knowledge with me . This fixes the issue if the status bar is not initially hidden . I m accepting your answer although it s more a hacky workaround for a nasty bug than a clean solution .

Answer : I ve tried your code in a lot of combinations : Xcode 5.0.2 beta one iPhone 5 iPhone 5s and various Simulators . This issue isn t reproducible when using new beta iOS SDK so seems like this bug was fixed and you don t have to worry about it anymore . Comment : Excellent .

I had this previously working by adding a subview to the navigation bar but it seems stupid to do that when I only want an image .

Answer : Trygve makes a presentation of DCI in http : oredev.org videos dci--re-thinking-the-foundations-of-oo .. . .. . DCI has been created to solve a problem in object orientation : it s too difficult to review OO code . The code for one use-case in OO is typicall spread out between lots of classes . To understand how the code works you must also know the relationships between objects in runtime . These relationships aren t set in code they depend on the situation . What DCI proposes is that code for a given use-case is separated out from the classes and put into a different artifact called context . Objects of different classes can enter into a relationship in this context and take part in interaction where they have different roles . The whole point of DCI is to make OO code more readable That s how I would pitch it . Comment : +1 for presentation link Comment : Yep +1 for the link . I was actually searching for it Comment : Nice answer wanted to add by bit that one of the roles is to ease change in business logic as context represents the actual business logic and interactions among DUMB model objects . So it would be easy to change the business logic if it is present at one place which will also reduce the amount of bugs introduced .", "Question : DDD is Domain-Driven Design it is a methodology that include ubiquitous language root entity value object and aggregations. . .. . .. .

Is it really the successor to MVC or just another pattern And what are its pros and cons Comment : +1 Good question .. . Answer : A good question and an often occurring question . The short answer is that it s a paradigm on it s own based upon the founding ideas of OO by Kay Dahl and others . It was created by Trygve Reenskaug as you note with several goals in mind . One of them being tha aim of making IO operations first class citizens of the program . not IO as in disk operations but all communication between two different objects . Another important goal of DCI is to split what the system does functionality behavior from what the system is data", "Question : DDD is Domain-Driven Design it is a methodology that include ubiquitous language root entity value object and aggregations. . .. . .. . DCI : Data Context Interactions is a programming paradigm invented by Trygve Reenskaug . how can I combine with them in a new system .. . Answer : If you read through this https : msdn.microsoft.com en-us library jj554200.aspx I believe the DCI notion of a context would be synonymous with a process manager . Instead of the process manager calling methods on the aggregates it would apply roles to the aggregates and coordinate using those . A bounded context could have several process managers aka contexts . What do you think", "Question : Most examples of a DCI Context are implemented as a Command pattern . When using Dependency Injection though it s useful to have the dependencies injected in the constructor and send the parameters into the executing method . Compare the Command pattern class : .. . .. . With the Dependency injected class : .. . .. . The last one seems a bit nicer but I ve never seen it implemented like this so I m curious if there are any things to consider . Comment : There only very little in common between command and DCI . DCI is not a pattern but a paradigm on the level where you find OO and FP Comment : Of course I just saw some similarities in the implementation not suggesting anything else . : Comment : The code you describe looks a lot like the use-case driven design described here http : www.cuttingedge.it blogs steven pivot entry.php id 91 . Just replace the name Command with SomeRole and CommandHandler with SomeContext . Comment : It does but I m a bit regretful that I mentioned DCI and a pattern together it leads to confusion . Also the answer where I commented about the problem with parameters in the Execute method has been deleted . .. . Answer : There s a contrast between Command and DCI . In Command you distribute the interaction between objects in DCI you centralize the interaction through rolemethods . In the MoneyTRansfer example the accounts will not have the ability to withdraw or deposit becasue they are simple data with no behavior . however in a context such as Transfer that behavior will exist for the roles . So when the source account role is bound to an account object the account object gets the withdraw behavior and the same is true for the destination account . In the command-pattern they have the behavior but the execution of the behavior is scripted in the command object and can be passed around . The entire interaction is not part of the command object but typically distributed between the participating objects . In Marvin a language build to support DCI as a result-of the realization that most modern languages only partly supports DCI you can only bind roles to objects in the constructor . How you call the constructor is of no concern to the context . This ensures that the binding is done once for all roles . Rebinding is then only possible by instantiation of another context . This is not a constraint from DCI but a design choice for Marvin . To the question about whether or not an context method can take arguments it s a bit philosophical but as far as I remember the last time I debatted it with Trygve Reenskaug we agreed that they could take arguments and I know that I ve implemented a few examples the moneytransfer at the DCI site http : fullOO.info included where they do .", "Question : A recent debate with a co-worker about different approaches to design and code the models in a Rails application brought me across DCI in the context of Rails http : andrzejonsoftware.blogspot.com 2011 02 dci-and-rails.html .

There s quite a few places where it seems that you ve not quite gotten what DCI is making it even harder to answer some of the questions in a DCI context . I can help you with the DCI stuff if that s the goal but you d need to narrow down the scope then Comment : I d mostly like to understand what is DCI . As for a Rails implementation a simple example or even a two-line explanation would be great . Comment : Great question . I didn t know until reading this that there was a name for the paradigm that I ve been hankering for just lately . I ve been looking at code I maintain that I didn t write and thinking What this needs is classwise separation between data and behaviour . I guess that this is precisely what DCI is trying to do . Comment : Not DCI specifically but Googling for Rails service objects will give a taste of how DCI-like concepts can be applied .

Answer : At the heart of DCI http : www.artima.com articles dci vision.html is the cognitive tools it provides the developer . I m not sure if you ve seen all the great James Coplien Trygve Reenskaug http : www.tele-task.de archive lecture overview 6269 lectures but I will try to distill the gist of it for anyone new to the concepts . It is about moving system behavior out of the systems interacting domain objects data entities or what the system is and into behavior objects what the system does as first class citizens which mediate the collaboration between objects by injecting them with functionality in the context of a use-case just-in-time . Think BDD . We code the behavior not across many objects like particulates of functionality spread out all over our data objects which are highly coupled to the persistence layer but within cohesive objects that exist solely for a use-case story and which inject capabilities into and coordinate the interactions of these dumb data objects . Like sheer layers of a physical architecture slowly changing data objects are not loaded up with rapidly changing feature implementation that they carry around all the time . Rather Ruby provides us the ability to easily inject the behavior into the objects at runtime when if needed only in the context of a use-case . As an example in ROR if you have a controller action involved in a use-case in which there is an event probability matrix where most entries may be triggered in only a small percentage of requests then instantiating a network of bloated behavior-heavy objects with the knowledge to execute every event for every possible use-case of the data is unnecessary . Also not having to dig through 18 files in my text-editor to understand how that interaction works vs . having all the logic cleanly abstracted to patterns in an interface provided by the context object is a definite plus as well . Regarding your question about another layer of abstraction between controllers and models in rails I m not sure which other one your referring to . Regardless Yes . By all means . No problem . Design patterns http : en.wikipedia.org wiki Command pattern and Uncle Bobs SOLID http : en.wikipedia.org wiki SOLID 28object-oriented design 29 principles are pretty much generally accepted best practices in OO design . Both of these strongly encourage loosely coupled abstractions between policy and implementation . They both help avoid catostrophic brain dumps of roman empire demolishing magnitude because they provide a common framework everyone understands . DCI for me provides the same type of cognitive framework but for making a system easier to comprehend and deal with effectively and this is the holy grail for any object oriented designer .", "Question : null .. .

Answer : The impression I got is that it s not a successor to MVC so much as a complement for example figure 5 in the artima article on DCI http : www.artima.com articles dci 5Fvision.html has both . I think it s supposed to help make the distinction between model and controller more sane or maybe between different part of the controller or different parts of the model . The basic idea seems to be to split logic for particular actions our of your data classes and move it to traits mixins whatever one per user action . You ll have many small pieces of code instead of a few large pieces . Also it sounds like adding new mixins is supposed to be better than adding functionality to your base classes . The code for individual actions will probably I think be more spread out but code for different actions should be more clearly and obviously separated . Comment : The code for individual actions will be less spread out as they will be put into the contexts . Comment : The last part of the answer contradicts the goals of DCI . An explicit goal of DCI is to keep the parts of an algorithm in one place . Usually examplified by keeping the implementation of a use-case in one place", "Question : All the examples of DCI I ve seen seems to be based on the object as the ultimate holder of information and the transaction boundaries are defined inside the methods . I would like to see an example of a persistent application where there is some sort of persistence layer i.e . where there can be duplicate object copies of the underlying persistence storage and where a change to an object is a change to a copy that will later be persisted . Does DCI work for that model at all Comment : any application that can be implemented with OO can be implemented with DCI . DCI is OO but enforces constraints to how to do OO . That said there are no objects in a persistence layer nor are there copies of an object there are classes in a persistence layer and multiple objects representing the same information . DCI is not concerned with classes they are a language feature and syncronizing different representations of what s suppossed to be the same is an issue ortogonal to all paradigms that accept side effects and can be solved in various ways in them all too .. . Answer : DCI is a paradigm and just as you can build an application using any other paradigm with persistence execluding pure FP since persistence is a side effect so can you with DCI . It s not mentioned in DCI examples because it s not a concern to the paradigm and is unrelated to understanding the paradigm . That said you re not the first to ask the question and will not be the last I m sure . The concern of persisting data is in general ortogonal to DCI . DCI tries to partition the design into .. . .. . What the system is .. . What the system does .. . .. . The first is the domain-model and the second is the functionality of the system . Whether what the system is is kept in memory flat files or a DB is important of course but a separate concern and is usually implemented using restricted OO https : groups.google.com forum msg object-composition umY w1rXBEw hyAF-jPgFn4J Comment : What you say makes sense but I think the reason it s brought up so often is that e.g . in the Artima article there s explicit use of transaction boundaries . This implies something about persistence and as such leaves people with the question . Comment : @nilskp agreed and that s where restrict OO comes in . Most DCI examples omit the restricted OO parts for brevity . I m in different boat than some of those examples since I tend to use DCI one a lower level than the examples just as Guge mentions in a comment I m might very well use DCI in the persistence layer", "Question : In his book Aspect-Oriented Software Development with Use Cases http : rads.stackoverflow.com amzn click 0321268881 Ivar Jacobson introduces use-case slices . It seems that DCI and use-case slices are based on the same or at least similar idea . What are the differences between DCI and use-case slices Comment : I have similar impression - I think Jacobson was trying to do DCI since beginning of the use cases but I think use cases are useful in a quite different way.. . .. . Answer : It seems to me they both derive from Feature Oriented Programming . The idea behind is to arrange the design of a system architecture in a set of views each one defining the way the system address a function . In use-case slices this is done at the M1 level of the OMG MDA Stack . It defines a UML profile to model the way aspects extend system classes to add properties and operations aimed at realizing specific use cases . In DCI this is done at M0 code basically by means of OO techniques not aspects as far as I understand . Anyway it is a good question years ago I had the same concern about Context Oriented Programming and Aspect Oriented Programming . I am still a bit convinced the former is a specific application of the latter . Comment : So you say that DCI is architecture reflecting use cases and use-case slices are a modeling technique for use cases unrelated to architecture right That is the way I understand it . Comment : They are both an architectural reflection of use cases . I guess they just exploit different technologies in different level of abstractions . Use case slices define a modeling approach to design architecture of objects and aspects satisfying use cases . Hence they are related to architecture as well . Comment : They first taught us how important was encapsulation and now the want us to break it be means of aspects or other crosscutting constructs : Comment : So you say use-case slices are ment to be visible in code Can you give reference to that I read only in Jacobsons summary they should be a modeling concept.. .

Answer : DCI doesn t really concern itself with persistance . Comment : What does that mean That it s an orthogonal concern i.e . DCI is outside that scope because it doesn t matter Or it s a valid concern that is just not addressed by DCI Comment : Persistance is always a valid concern but DCI is more of a paradigm than an architecture . So I think it s orthogonal . DCI has a lot to say about data but not so much where it comes from or where it goes .

Mmmh seeing in code the interaction between different components of a software is an attractive idea . I tried to find examples of DCI in javascript unsuccessfully . Then I started wondering . Isn t the DCI pattern opposed to the evented programming pattern Evented programming is trendy in javascript i guess because it allows decoupling and because classical inheritance concepts are not native to js . I think I understand the benefits of evented programming but I also noticed that debugging can be damn hard when it requires to follow event message . Is it correct to say that both concepts are opposed Or did I got it wrong Is there some example implementations of DCI in js that I missed What should I look at in order to dig the concept .. . Answer : Firstly event programming or inheritance are ortogonal to DCI . You can do DCI without inheritance and with event programing or without . JavaScript is in somerespect one of the best languages to do DCI in . Most languages has some issues with following DCI stricyly . In JavaScript the issues are could be solved if there was a finalizer but the lack of a finalizer means you will have to dispose your self meaning some noilerplate code . I ve written an example in JavaScript that I will put online on http : fullOO.info where you will find the examples Trygve Jim and I have created together with some other people have created as well . fullOO.info is also the answer to where you could go to get more familiar with DCI or you can join object-composition a google group for discussion regarding DCI . The example I ve written in JS is the canonical DCI example money transfer and the interesting part that is everything but boilerplate library code can be seen below : .. . .. . The rest can be seen at http : jsfiddle.net K543c 17 Comment : Thanks a lot very interesting . I will study the code once I am back home . But could you expand on the difference between dci and evented isn t an event send by one component and listened by another one an interaction between components When I watched folk.uio.no trygver themes babyide babyide-index.html http : folk.uio.no trygver themes babyide babyide-index.html I had events in mind . These days events are used for everything in js webapps . They are used to access methods on other components instead of direct access in order to achieve decoupling and prevent the app to break completely if one components breaks . Comment : @olivvv Events are just another way of sending messages between objects . DCI is concern with capturing in code which object send which message to what object . You could also view events as something that starts a context . So being event-driven is orthogonal to DCI but I guess you are actually referring to asynchronous which is a very different thing Comment : No I am not reffering to asynchronous but pub sub communication . For instance one component watches keyboard and mouse activity and broadcast events for other components to let them know if the user is active or not . There can be a lot of components listening . How would a context take that into account Comment : @Olivvv By definition all communication between objects in DCI is captured in a context one context for each network of communicating objects so you ve would simply have roles that communicated . That said it is border territory for DCI at present .

Hope that helps", "Question : What are possibles designs for implementation of the DCI data contexts interactions architecture in different OOP languages I thought of Policy based design Andrei Alexandrescu for C++ DI and AOP for Java . However I also thought about using State design pattern for representing roles and some sort of Template method for the interactions.. . What are the other possibilities Comment : From the original paper there are also traits in Scala and open classes in Ruby . My Stete design pattern suggestion is wrong because if I understand DCI correctly the data should be isolated from knowing abou all the contexts in which it can be . Comment : Your understanding is correct it s one of the main concerns of DCI to make what the system is data independent of what the system is .. . Answer : In Java without byte-code generation I would use Decorator pattern for contexts however I will instead of classes decorate interfaces which will be more flexible . Data than will be represented through classes implementing the interfaces . The interactions will be done using manual dependency-injection into Template methods . Comment : DCI is tough in Java but using Qi4J get s you very close . The main problem that arises from different implementations in Java is identity problems . DCI is about objects and not classes . The decorator pattern is class based . In DCI the behaviour of an already instantiated object is extended with role methods . Those methods are internal to the context not some other class nor some other object . In other words you can t do DCI with the decorator pattern", "Question : What is the best description of Data Context and Interaction DCI http : www.gertrudandcope.com-a.googlepages.com thedciarchitecture to pitch it to an organization It s created by Trygve Reenskaug http : folk.uio.no trygver the creator of the MVC-pattern http : en.wikipedia.org wiki Model-view-controller . Is it really the successor to MVC or just another pattern And what are its pros and cons Comment : +1 Good question .. . Answer : I think improved system comprehension is a huge win for any organization but you could also make the case that DCI is an improvement on MVC due to the following additional factors : .. . .. . 1 . Cleanly separating system behavior and data provides numerous benefits to data aggregation activities including more performant real-time analytics due to smaller footprint of domain objects . 2 . Data object and behavior object reuse is much easier across functional divisions when they have their own place to live rather than being particulates as-if randomly placed across a subset of the mixed data behavior objects in a system . 3 . As BDD is becoming the defacto agile methodology the organization will be leap years ahead of the rest of the industry in this practice and possibly a role model for other like minded organizations .", "Question : I am working with AngularJS for my latest project . In the documentation and tutorials all model data is put into the controller scope . I understand that is has to be there to be available for the controller and thus within the corresponding views . However I dont think the model should actually be implemented there . It might be complex and have private attributes for example . Furthermore one might want to reuse it in another context app . Putting everything into the controller totally breaks MVC pattern . The same holds true for the behaviour of any model . If I would use DCI architecture http : www.artima.com articles dci vision.html and separate behaviour from the data model I would have to introduce additional objects to hold the behaviour . This would be done by introducing roles and contexts . Of course model data and behaviour could be implemented with plain javascript-objects or any class pattern . But what would be the AngularJS way to do it Using services So it comes down to this question : .. . .. . How do you implement models decoupled from the controller following AngularJS best practices Comment : I would up-vote this question if you could define DCI or at least provide the spelled out form . I have never seen this acronym in any software literature . Thanks . Comment : I just added a link for DCI as a reference . Comment : @JimRaden DCI is Dataq Context interaction and is a paradigm formulated firstly by the father of MVC Trygve Reenskauge . There quite some litterature on the subject by now . A good read is Coplien and Bj rnvig Lean architecture Comment : Thanks . For better or worse most people don t even know about the original literature by now . There are 55 million articles about MVC according to Google but only 250 000 that mention MCI and MVC . And on Microsoft.com 7 . AngularJS.org doesn t even mention the DCI acronym : Your search - site : angularjs.org dci - did not match any documents . Comment : Resource objects are basically the models in Angular.js. . am extending them . .. . Answer : DCI is a paradigm and as such there s no angularJS way of doing it either the language support DCI or it doesn t . JS support DCI rather well if you are willing to use source transformation and with some drawbacks if you are not . Again DCI has no more to do with dependency-injection than say a C class has and is definitely not a service either . So the best way to do DCI with angulusJS is to do DCI the JS way which is pretty close to how DCI is formulated in the first place . Unless you do source transformation you will not be able to do it fully since the role methods will be part of the object even outside the context but that s generally the problem with method injection based DCI . If you look at fullOO.info http : FullOO.info the authoritative site for DCI you could have a look at the ruby implementations they also use method injection or you could have a look at here http : runefs.com category dci for more information on DCI . It s mostly with RUby examples but the DCI stuff is agnostic to that . One of the keys to DCI is that what the system does is separated from what the system is . So the data object are pretty dumb but once bound to a role in a context role methods make certain behaviour available . A role is simply an identifier nothing more an when accessing an object through that identifier then role methods are available . There s no role object class . With method injection the scoping of role methods is not exactly as described but close . An example of a context in JS could be Comment : Thanks for elaborating the DCI stuff . It is a great read . But my questions really aims at where to put the model objects in angularjs . DCI is just in there for reference that I might not only have a model but split it in the DCI way . Will edit the question to make it more clear .", "Question : I ve been playing around with DCI after following along with The Right Way to Code DCI in Ruby http : mikepackdev.com blog posts 24-the-right-way-to-code-dci-in-ruby . I find that I keep wanting my roles to add properties to my data objects . For instance if I have a user object . The user may play the role of a customer . To make this work I need to add a cart method . Does the shopping cart really belong in the user object It feels like the role should add the cart to the data object as needed . .. . Answer : In general DCI data objects should consist of just the data plus very basic domain logic like basic validation logic . And DCI roles should be purely behaviour . Adding the cart to the user in a role feels like a violation of that second . Maybe your missing a data object-type or a role Remember roles can use other roles from the context so maybe your role should just expect an object playing the role of a cart to be part of the current context . Comment : I hadn t thought of a context taking a cart . I ll give that a go and see how it turns out . Comment : @JonMR Did you ever go any further with this I m in a similar place and am curious what you wound up doing . Comment : @JStroop I didn t get much farther with it unfortunately . For my eventual DCI use-case I just dropped the concept of roles . In that case add to cart just moved into it s own class . Hopefully that makes sense . : Comment : @JonMR It does I think . DCI seems to really shine when you have complex or highly customized interactions between two objects when it s just one class that needs to do something it starts to feel like modelling overhead and concerns or plain old instance methods seem a lot easier .

Comment : This goes close to the border or opinion-based or opene-ended discussions . However I don t think it actually crosses it I think it s on-topic . Comment : @LennartRegebro thanks for the info . This type of feedback is invaluable for posters . Without this type of feedback it is sometimes very difficult to know why your question is considered a bad fit . .. . Answer : A non-pure OO language in this context is a language were not everything is objects . Java for example have primitive-types which behave differently than objects . For example Java s primitive-types are passed by value while Java passes references when it passes it s objects . In contrast Python treats everything as objects and although it has built-in types it has no primitive-types everything is objects . I think you misunderstand the reference to classes . I don t think they say that a pure OO language does not have classes . Comment : Is there an OO language that does not have classes I have never encountered one . Comment : @SHC Javascript for example . Comment : Another OO language without classes : Self . Comment : Part of the point of that qoute AFAIK is that class-oriented languages like Java C C++ etc make us think in classes more than in objects . Thus more class oriented than object oriented . Comment : Classes are write- and compile-time artifacts . Objects are what exists at runtime . Thinking more in objects than in classed brings our thinking closer how the system will run and by consequence to what the user interacts with .", "Question : I m writing a simple webgame to experiment the DCI pattern and I was wondering how to test the context properly . https : gist.github.com 1718889 .. . .. . I have a context CharacterAttacksAnotherCharacter which take two characters and extend them with two roles Attacker and Target . Then the context is executed . But how can I test the behaviour of this execution instead of the implementation Thanks Comment : I think depend how do your attack method . You can t stub it if you want test behaviour . .. . Answer : In general testing an interaction in a DCI context should be fairly easy . One of the goals of the context is to be self-contained so binding roles to objects that suits the testing should be straight forward . If it s not that s probably a sign that it s not really DCI . I have a hard time finding any role methods in your code . That might be due to my lack of ruby skills . In general the interaction should be a complete algorithm and that is what you would want to test when creating unit test for a context . However a goal of DCI is to create a verifiable code unit so if that goal is reach there d be other parts of the code where the testing efforts yield a higher value compared to using reviews to verify the implementation of the context and it s interactions" ] }

If you observe and compare test cases somethingA and somethingB you will see what is needed to cause the UUT to once go in the path that calls somethingA and once to go in the path that calls somethingB . Let s take for example .. . .. . Here we are saying to CppUmock to expect a call to function read from i2c to ignore what the parameters are and this is of fundamental importance to return-value + 1 or anything else you fancy that is different from value .

Answer : Often its a good idea to create these static-variables in a separate file some like to call it scaffolding so that you can get away from including the .c . The basic theory behind this is that if you are always including .c files it quickly becomes impossible to unit test since the whole idea of unit-testing is drilling down and testing one bit of code without depending on the rest of it .

Thanks in advance . Comment : Apparently you want to debug rather than perform unit-testing .. . .. . Answer : There are two main possibilities : .. . .. . 1 . The difficulty of testing is showing that the interface provided by the module is incomplete . 2 . Your unit-testing is prying into the internals of the module in a way that consumers would never need to do . If the problem is an incomplete interface then you can add the extra interfaces that make the module more easily testable and more generally usable . For example if the static-variables are counters of some sort you might need to add a reset method to set the counters back to zero ready for the next part of the unit-testing or in the more general use-case to allow the statistics to be zeroed so that you can accumulate the statistics afresh . If the problem is unit-testing needing to probe more deeply than consumers need to probe then I don t see anything wrong with the test code using include sourcecode.c . It keeps the module code clean for general use it allows the unit test to probe more deeply than it would otherwise . It converts the test code from black-box-testing to a form of white-box-testing - the test can see more of the tested code than a regular black-box test can . But that s sometimes helpful . It is often an intermediate stage during development . Once you have all the black-box-testing in-place you may not need to be concerned with probing the internals in the same way - until you make changes . Comment : I think in my case the intarface isn t incomplete . I m inclined to include the whole c file to my test case . Technically it means they are in the same compilation unit so the test case can see the static-variables . But to be honest : I don t like the idea . It looks like a workaround . Is there any solution which I didn t notice Comment : No that s why I outlined the two possibilities . If the interface is incomplete I recommend completing it . For example I am working on some locale-related formatting code . The simpler functions use the current locale but testing that would be a complete bitch . I ve completed the interface by providing generic functions which take a locale as an argument and the most easily used functions without the locale simply find the current locale and then call the generic functions . I can test the generic functions with all sorts of oddball locales in ways which were not possible otherwise . Comment : Thanks Jonathan I realized that is a viable option . So I included the whole c file and gave init value to the static-variables . I can test the module now . Comment : See also How to test a static function http : stackoverflow.com questions 593414 .", "Question : I am trying to compile the following test application using CodeBlocks and CppUTest however no matter what I do I always get the undefined-reference error . I compiled CppUTest with cygwin in codeblocks I use MinGW . The project directory just has two files main.cpp and tests.cpp I am trying to get this to compile . This is the main.cpp file : .. . .. . This is the tests.cpp file : .. . .. . I already have the libraries libCppUTest.a and libCppUTestExt.a now I have to link them to the project . For this I ve attempted the following : .. . .. . In build options add CppUTest include to search directories for the compiler . In build options add CppUTest lib to search directories for the linker . In link settings add libCppUTest.a and libCppUTestExt.a to link libraries . Also tried with the full path to these libraries . I think the problem is not Codeblocks because I ve tried with every guide I ve found to link the libraries and I always get undefined-reference . I ve also tried to add these as global settings but I get the same error undefined-reference . Any ideas Comment : This is no C code . Do not add C tag for C++ . Comment : Ok that s fine . Apologies . Comment : Libraries in C++ have no standard format and are not inter-operable even with different compiler versions . I m suspecting it s because of the different compilers . Read about name-mangling in C++ shared-libraries . Comment : can t you use Cmake on windows to compile it and can t you use DLL libraries Comment : I tried to use Cmake GUI and MinGW make however CppUTest 3.7.1 latest version doesn t build with MinGW due to an issue of this compiler with pthreads . So I used cygwin to compile it . .. . Answer : As pointed out by @Sreekar the problem is that I was using MinGW in codeblocks and the libraries were compiled with cygwin . Changing the compiler to cygwin in Codeblocks fixed the issue for me . This describes the process to change the compiler to cygwin in codeblocks if needed : .. . .. . https : www.youtube.com watch v oVmd0P85D8o", "Question : I am getting started with Test Driven Development for embedded C and I started to read the book : Test-Driven development for embedded C in which they recommend two development system test-environments : Unity and CppUTest . Thus I decided to download the code of both and also downloaded and installed Cygwin in order to compile the stuff . However once I download everything I get really lost since there is not good documentation of this kind : .. . .. . 1- First go to XXX . 2- Run XXX . 3- Copy XXX file into XXX folder . 4- And voila all set .. . .. . The only thing I find when I download CppUTest and Unity is a ton of folders with makefiles and stuff and some READMEs that for me are like written in Chinese . The furthest I got was to compile the CppUTest and run its tests and that is it . So here is my question . Imagine that I already have my Module.c Module.h and ModuleTest.cpp . What do I have to do to compile it and run the test I wonder if you have experience with this tools and can give me some tips and advices . Thank you and best regards . Comment : http : cpputest.github.io manual.html seems clear to me . But I miss why you think embedded C and cygwin should be related . Comment : Well I need Cygwin to follow the examples in the book . I didn t go much further in the book but I guess that you can simulate hardware in some way for example if you have to write to an array of leds you just need the address where they are located but the program doesn t actually care if this address is actually connected to hardware or not so you could just have virtual leds . Also I followed that tutorial but didn t get anything . So lets assume I have my module.c module.h and test module.c what do I have to do to run the test .. .

That is also basically what is written in README.md Comment : Hello Matzeri you are right and I modified the title and the text body to make my question more clear . I hope it is more understandable now . Regarding your answer I already managed to do that compiling CppUTest but my problem is how to run the first test of one of my modules .

But in this way I produce not really usable code so I was wondering if there is possible to mock just the global variable . .. . Answer : We often forget about the linker . We can use a different object file to mock an interface . This mock-obj would contain a different definition of your global . But current unit test frameworks only work on code lebel.. .

Your sample code looks fine to me you don t need the semicolon after EditorFor but that wouldn t cause a crash . Are you still having this problem Any chance you could post send the project .. . Answer : I have found tow situations where this error will occur : .. . .. . 1- When you forget to copy HtmlAgilityPack.dll to production server That s me 2- When you use @form.EditorFor and you have a UIHint attribute on the corresponding model s property and defined an EditorTemplate . AND you have an error in the template file . But instead of seeing the actual error you see this error .", "Question : I m experimenting with Fluent Bootstrap but am finding the API documentation sparse .

Answer : Sorry it took so long for me to find this - still not used to coming on StackOverflow and searching for my libs : . Unfortunately you can t do what you want to at this time . As far as I know you wouldn t be able to do it in straight ASP.NET MVC either . The problem is that calling EditorFor really just farms out to an editor template Scott Hanselman has a nice little real-world example on his blog http : www.hanselman.com blog ASPNETMVCDisplayTemplateAndEditorTemplatesForEntityFrameworkDbGeographySpatialTypes.aspx . Depending on the model property type the editor template could have an input or it could have a textarea or it could have a whole bunch of form elements for a really complex editing experience . Since we don t know what the EditorFor might return we have no way of knowing to which element or even if the extra attributes should be applied .", "Question : null .. .

However I am not sure how to go about this . The JRI homepage http : www.rforge.net JRI says that the package is bundled in rJava http : www.rforge.net rJava . So I downloaded rJava-0.9.3.tar.gz from the rJava Files section http : www.rforge.net rJava files and unzipped it getting among other things a lot of Java source files and their corresponding classes in the src java folder plus 2 JARs JRIEngine.jar and REngine.jar in the inst jri folder . The JRI Files section http : www.rforge.net JRI files though in addition to the above 2 JARs also includes JRI.jar and all three of these libraries are more recent than the 2 in inst jri . In addition none of these 3 JARs includes the binaries for the classes found in src java which appear to be necessary for calling R from within Java . Running make all in the java src folder seems to just execute some tests and no JAR is produced . I would expect that all necessary classes come bundled in JAR files so that they could be easily added in the classpath and in IDE projects e.g . in Eclipse . How can I get to that point .. . Answer : Use install.packages rJava in R - that will install rJava which includes JRI . You ll get the same effect by using R CMD INSTALL rJava 0.9-3.tar.gz . Both are the documented ways to install R packages . Make sure you have JDK installed and configured R with Java support before . Once installed you can ask R about the location of JRI with system.file jri package rJava .. . .. . Note that in order to use JRI you will need to setup the environment properly typically using R CMD and set java.library.path to include the JRI location . You may want to scan the stats-rosuda-devel mailing list which is the canonical place to ask about rJava JRI . Comment : Thanks for the answer . I read about the install.packages command but was puzzled as to how I would make the result work with Eclipse . I have now run it and added a User Library in Eclipse that points to the 3 JAR files installed . Given that Eclipse takes care of Java-related path declarations should that work out of the box Comment : No JAR files alone are not enough - you have to make sure you have java.library.path setup to find the JRI dynamic library and also set environment-variables required by R such as R HOME . I don t use Eclipse so I don t know how it handles those settings . You can have a look at the run script and the JRI examples . Comment : Indeed . R HOME can be set in the Project Preferences Run Debug Settings whereas for the ld.library.paht one can edit the Native library setting in each of the 3 JARs of JRI as per this StackOverflow post : stackoverflow.com questions 957700 http : stackoverflow.com questions 957700 how-to-set-the-java-library-path-from-eclipse .

Answer : What you are seeing is the visibility flag maintained by R which tells the regular event-loop when to print and when not . See withVisible in R for details . However you really don t want to get into re-implementing the R event-loop . Instead JRI allows you to have R do all the work for you - you just implement the console callbacks RMainLoopCallbacks to handle all your console I O and then start the event-loop .

But I had to use : re.eval .libPaths c : users foo Documents R win-library 3.2 in windows .", "Question : null .. . Answer : Here s the situation . I am attempting to load the JRI for R integration in Java . Here s what I know to make it work : .. . -Make sure that the path to the JRI DLL is in the java.library.path so java can load the native library . -Make sure that the path to the R DLL is in the system path so the system can resolve a DLL dependency . If both of these are true before my application loads the library will load with no problem . However I am having problems with loading it if I try to do it automatically without use involvement . Here s how I am trying to make it work : .. . -If the JRI DLL is not in the java.library.path add it at runtime using reflection and try to load the library again immediately - this works great . -If the R DLL is not in the system Path add it using the setx command . The second step is where I am hitting huge problems - I still see an error with finding the R DLL which is a dependency of the JRI DLL . My code sets the system Path as it should immediately as I check this in the control panel however loading the JRI library fails on a dependency . I know setting the path correctly fixes the dependency issue if I set it before running my application so why it does not work in this case I do not understand . If I kill my application and start it from scratch it works fine as the Path was set from the last time it was run . When a dependency failure occurs on loading a DLL where is the error actually happening Does Java look for the dependency of the JRI DLL I had assumed Java played no part in the resolving a dependency of a DLL was I wrong If the operating-system is responsible for resolving the dependency of a DLL then why is my Path change not recognised Do environment-variables get passed to a DLL when Java tries to load it I should add that I am developing this in Netbeans however I see the same behaviour if I build a JAR and run that directly in the terminal . I often see that a Path update is not seen until a restart of Netbeans however I had thought that a DLL resolving its dependencies would use the Path directly . It s pretty frustrating so it d be great to hear your thoughts on this . Comment : setx doesn t change the environment-variables for the current process or for child processes only for brand new processes . To be more precise only for processes created by applications such as Explorer that explicitly look for changes in the environment variable settings . In your case you need to change the environment-variables for the Java process . I m not sure how you do that hopefully someone else can answer but setx won t do it . Comment : @HarryJohnston My confusion is whether the thing resolving DLL dependencies is receiving its environment through Java or whether it is a system component and entirely separate from the the process hierarchy I create when I start my application . Does loading a native library cause a sub-process to be created Comment : I should also add that I can and do change the environment-variables in the Java process but this appears to have no effect on the resolution of the DLL s dependencies though it does allow my DLL to be found in the first place by Java . Comment : In cases where the PATH is used in resolving dependencies which seems to be true here since setting it ahead of time works then it is read from the environment variable block of the process that is loading the DLL . The first thing you should double-check is whether you ve successfully changed the process environment-variables . You can do this with Process Explorer which is available free of charge from the MS web site . This will also show you whether there are any sub-processes or not .", "Question : I m new to R and was attempting to call a simple rJava test program from java .

Answer : I believe Regasm must be run by an administrator . Regasm http : msdn.microsoft.com en-us library tzat5yw6 28VS.71 29.aspx can read the metadata within an assembly and adds the necessary entries to the registry which allows COM clients to create .NET Framework classes transparently . Once a class is registered any COM client can use it as though the class were a COM class . Therefore whatever is done with Regasm will be done for all users . So no when using regasm there won t be a situation where assemblies are registered only for certain users on a machine or domain . Caspol can be run by users other than administrators . Caspol http : msdn.microsoft.com en-us library cb6t8dtz 28VS.80 29.aspx enables users and administrators to modify security policy for the machine policy level the user policy level and the enterprise policy level . If you do not currently have administrative permissions your default view is the Users view . A list of the Security Policy Levels http : msdn.microsoft.com en-us library 628s5x1x 28v VS.80 29.aspx shows the variations . Therefore Caspol allows user and machine specific security policies and the type of user running Caspol will have an impact on what can be achieved . So yes when using Caspol there can be a sitation where assemblies have a different security policy based on machine and user .", "Question : I m attempting to expose our library via COM but seem to be fighting the tools more than the actual problem . Regardless of how I write my COM exposed class I get the warning : XXX.dll does not contain any types that can be registered for COM interop marked project as Register for COM interop in the project properties . Even the simple class below as the only class in an assembly that is signed and marked with ComVisible false still warning persists : .. . .. . I ve tried to run regasm from the command-line on the output which gladly states Types registered successfully . However running with the verbose switch no extra information is displayed I seem to recall that it lists the name or perhaps just the number of registered types . Also tried running regasm with the regfile switch to generate a regfile which generates this : .. . .. . I m no COM wizard of any measure but the registration looks valid to me . However nothing seems to appear in the registry when running regasm on the assembly . So my question is whether I m missing something in my simple example to have the registration work am I seeing false indications and is the registration actually correct and how can I better determine if the COM registration actually works .. . .. . EDIT : Using the alterations suggested by Kev I could not avoid the warnings from VS2008 but I could actually get something registered in the registry using regasm directly nothing in the registry from just the VS2008 integration . I then tried to remove the simple class so I had an empty assembly . Running regasm on this did not report any sort of warnings only Types registered successfully . I see warnings like RegAsm : warning RA0000 : No types were registered when running RegAsm on some of my other assemblies which may be incorrectly exposed to COM .

I just can t reproduce the problem you re having . Comment : Thanks for being so persistent Kev . A re-guiding of the COM exposed types and a reboot helped with the simple example . Still struggling with exposing types for larger assemblies though . .. . Answer : I created a class-library project based on your code as follows : .. . .. . In the project properties page select the Signing tab . Check the Sign the assembly checkbox and select New.. . from the Choose a strong name key file : drop down box . I then added the following class Example.cs : .. . .. . I then built the project then dropped to a command-line where the DLL was output from the build . To register : .. . .. . regasm.exe COMInteropTesting.dll register codebase tlb .. . .. . If your component needs to be accessible to multiple applications : .. . .. . gacutil.exe -i COMInteropTesting.dll .. . .. . This all worked fine on Windows 2003 32bit Windows 2008 32bit and Windows 7 64 bit . One gotcha though is that if you re testing the component with say CScript on a 64 bit system you need to run the correct CScript interpreter . If you registered the assembly using 32bit RegAsm.exe at C : Windows Microsoft.NET Framework v2.0.50727 then you need to run the 32-bit CScript interpreter at c : Windows SysWOW64 . Comment : Still same warning from VS2008...sigh... . However seems to actually appear in registry . Was hoping for a clearer indication of success . A side question : do I really need to add it to the gac if I register with codebase Comment : Ah...I have a COM component that we register in the GAC . That said I find your predicament very strange . Comment : Marking this as the answer as this will produce a working sample", "Question : Recently I wrote a class-library in C for use in Office applications including a critical Access application used by 70 people . For users with admin rights registering the DLL is trivial but getting the DLL working on other machines was problematic . Registering the DLL for use with admin privileges .. . .. . Build the DLL in Visual Studio . Ensure these options are selected on the project s Application tab : .. . Output Type : Class Library .. .

Add a reference to YourDll.tlb in VBA : Tools-- References .. . Verify that you can create an instance of your object .. . .. . What is happening Regasm is doing several things here . First it is creating a type library YourDLL.tlb which provides information about the classes that are in your DLL . Second it is storing the information about the library in the registry so that the system knows what you mean when you ask for a class to be instantiated as an object . To see what registry entries Regasm is adding you can run it with the regfile parameter : .. . .. . Regasm YourDLL.dll codebase regfile .. . .. . The regfile option is invalid with the tlb parameter . If the codebase option tells Regasm to include information about where YourDLL.dll is located on disk which is important for creating the objects . If you open YourDLL.reg in a text-editor you ll see the entries that Regasm is adding to the registry : entries to HKEY Classes Root which is really just a redirect to HKLM Software Classes . Unfortunately you need admin privileges to modify HKLM so this isn t going to work for our other users . There are a few other threads e.g .

Win64 Office32 . So how do you register a COM DLL created in Visual Studio for use in VBA 32 and 64 bit environments for the current user without administrative privileges .. . Answer : Setting up the registry files .. . .. . To register the components for use in 32 and 64 bit environments we are going to need to modify the registry file we created in our test case . Open it with your favorite text-editor . The entries should look something like this : .. . .. . Make sure that it includes CodeBase entries . Do a global find replace : .. . .. . Change HKEY CLASSES ROOT which is aliasing to HKLM Software Classes .. . To HKEY CURRENT USER Software Classes .. . .. . Copy all of the registry keys and their values which are listed below the keys to a second text file . In the second text file : .. . .. . Delete all of the keys and their related values that do not contain CLSID .. . Do a global find replace : .. . Change Classes CLSID .. . To : Classes Wow6432Node CLSID .. . .. . Copy all of the keys from the second text file to your original .reg file and save it . Remove the registration entries from HKLM by using regasm : .. . .. . Make sure things don t work .. . .. . In order to make sure that our change worked and that you re not just successful because of the registration you did with regasm originally we need to make sure that VBA cannot create the object right now . Open up your favorite VBA application and add a reference to YourDLL.tlb . Create a new procedure that is something like this : .. . .. . Run TestYourDLL . You should receive the error : .. . .. . If you don t receive the error your DLL is still registered . Save and exit your VBA application . Making sure they work .. . .. . Now run the YourDLL.reg that you created earlier to import the entries to the registry . If you get an Access denied message you forgot to change from HKEY CLASSES ROOT to HKEY CURRENT USER Software Classes .. . .. . Open your VBA application again and run TestYourDLL . You should now see Apparently this worked . in your immediate window . Congratulations You ve registered the DLL If you get an Automation error : The system cannot find the file specified -type error your registry file is either missing the Codebase entries or they are not pointing to the actual location of your DLL . Additional steps .. . .. . In my case I m going to be installing the DLL on a bunch of other users computers alongside my application so at installation time I ll update the CodeBase value to refer to the location where I m installing the DLL and I ll also install the registry entries through code rather than by executing the .reg file . But now that I know the required entries doing that is trivial .

This might not affect you but you should be aware of this limitation.. . Comment : @PetrSr : my experience was that the only entries that were missing entirely with regasm regfile were the CodeBase entries but regasm codebase regfile fixed that . Of course the 32-bit registration was also missing which is why I had to create those entries myself using the basic info as a base . Were you able to figure out which entries were missing for you Comment : The TypeLib and Interface IDs were missing and I was not able to get my DLL to work without them . As described in regasm documentation https : msdn.microsoft.com en-us library tzat5yw6 v vs.110 .aspx Anchor 2 these entries will always be missing with the regfile option . I tried to harvest the missing etnries directly from the registry but it proved to be a rather tedious task . I eventually gave up and asked my boss to register the DLL using his admin account for me.. . : - Comment : @PetrSr That would be really tedious . My test case didn t involve interfaces so I missed that .

Even if you insisted on trying this or if the assembly was intended for something other that an Add-in it s still a bad idea to try to use a .reg file to register the assembly . There is a lot more that would need to happen besides the COM registration for the assembly to work . Most likely you would have to add it to the GAC so that .NET can find it . Also a future version of .NET might require more information or different information to be added on the registry . Even today I suspect REGASM might need to put different information on different environments x86 vs . x64 . Comment : Thanks for the information . There are a few other articles regarding this here http : sharpshell.codeplex.com wikipage title Managed 20Shell 20Extensions referringTitle Documentation not all of which dismiss the idea . The reg file is generated by regasm itself and is supposed to simply replicate the changes made to the registry by the tool . There is also no need to add the dll to the GAC as the codebase flag stores the location of the dll in the registry . This being said I will have a look at the alternatives since this is proving to be troublesome . Comment : @Matt thanks for pointing out that link . It is an interesting summary on clearly conflicting views . Obviously the person has done a good deal of research .

Answer : Registering a shell extension requires writing more registry keys than normally required to register a ComVisible .NET assembly . You also have to write the keys http : msdn.microsoft.com en-us library windows desktop cc144110 28v vs.85 29.aspx handlernames that Explorer reads to discover extensions . You didn t mention at all how you took care of that this normally requires a custom ComRegisterFunction .

Comment : A system restore jumps to mind . Comment : What about a different user being logged in Comment : A different user wouldn t matter since the settings are not stored in the per user part of the registry . All COM registration entries are machine specific and I d assume it would be the same for caspol . .. . Answer : Are you sure that both regasm and caspol need to be re-run If so Hans Passant s suggestion of a system restore seems likely . However if it is just caspol that actually needs to be re-run a .NET Framework upgrade may be resposible . CAS policy is specific to the version of the .NET CLR under which the component is run so installing .NET 2.0 on a machine that previously had only 1.x might be causing your problem . The 32- and 64-bit CLRs also use different security policies so installing an alternate bitness .NET Framework might also cause you assembly to be loaded under an CAS policy that you have not yet tweaked . Comment : In fact it is just caspol that needs to be run . The assembly that needs caspol re-run is from a third party . Would the CAS policy on that assembly need tweaking after a .NET upgrade Comment : The version-dependency of CAS policy applies to all assemblies so it s quite possible .", "Question : I ve registered a .NET assembly using regasm.exe .

RegAsm output from Visual Studio 2010 built bTest.dll : .. . .. . For the above the bTest.csProj file had the Register COM interop was unchecked and RegAsm was done as a post build step . If builds are done with the Register COM interop checked thus enabled the Visual Studio 2010 builds correctly producing the bTest.tlb . However the MSBuild does not produce a bTest.tlb file and the resulting assembly still fails with the RegAsm 4.0 tool . Thank you in advance . Kevin Waite .. . Answer : I am using Jenkins and this job had inherited this specific platform setting form being copied from another very similar job that is also likely wrong as I know understand . Having this PlatformTarget x86 renders the resulting assembly .dll un-register-able . Be it with the Register COM Interop checkbox or be it with the RegAsm tool . And I doubt such a tainted .dll is what is wanted . If MSBuild uses these Jenkins defined command-line-arguments the resulting .dll will be unregisterable . And of course Visual Studio 2010 builds are not doing this and thus build successfully.. . .. . .. . Correcting to the following and job builds successfully and creates the .tlb perfectly fine too SOLVED Comment : Which version of regasm did you use if you used the Framework64 version against an x86 assembly you ll get an error message stating RegAsm : error RA0000 : Failed to load YourLib.dll because it is not a valid .NET assembly . Use the x86 version and it would work .", "Question : We have a .Net DLL that is available via COM interop which acts as a wrapper for a 3rd party s .NET library . This 3rd party library isn t needed in the vast majority of situations so isn t included in our setup but our wrapper DLL is . The problem comes when we try and register our wrapper DLL with regasm which fails with : .. . .. . RegAsm : error RA0000 : Could not load file or assembly 3rdParty.Application.Library Version 5.3.0.0 Culture neutral PublicKeyToken 0123456789abcdef or one of its dependencies . The system cannot find the file specified . As our wrapper already reports meaningful errors when it can t load the 3rd party library is there a way to make regasm NOT try and load it like delayload so our application can load it and get the error at run time This article http : www.thegatesofdawn.ca wordpress posts 2009 07 17 delay-loading-assemblies-in-net suggests that assemblies are already delay loaded but that doesn t seem to apply when registering COM interop assemblies . Comment : Similarish question : Dynamic load a .NET assembly with some other dll dependency http : stackoverflow.com q 26119874 588306 Comment : This does not bode well Regasm.exe does try pretty hard to avoid having dependencies involved . There s more than one way to register an assembly it just takes writing the correct registry keys . First thing to try is to use the Regasm.exe regfile option so you get a .reg file that you can then test with the dependency missing . A custom ComRegisterFunction is another way . Or just a plain installer that writes the keys directly . But do test the .reg file first . You can get a call stack for a failure from RegistrationServices.RegisterAssembly . Comment : Thanks creating a registry file and importing it separately was joint last resort with late-binding everything and not referencing it at all . Comment : The ComRegisterFunction doesn t replace the whole DllRegisterServer equivalent but is rather called per type that needs registering and will still hit the same assembly resolution problem . Writing direct to the registry may well be the only option . Comment : Hmm as long as you have no idea why the dependency is needed you can t know if ComRegisterFunction is going to fix it . Show us the call stack you get from RegistrationServices.RegisterAssembly if you want help . .. . Answer : Typically .NET dependencies are delay-loaded but the delay is until static construction of a type containing a method or field that references something in the dependant assembly . And since RegAsm uses reflection to walk through all types in the assembly this will always load all dependencies . One thing that you may be able to do to mitigate this is to break up your COM assembly putting anything that references the non-distributed library into a separate non-COM library that you always distribute . It s likely that this second library will be automatically loaded as RegAsm scans the first but it shouldn t load the third as long as you keep its types out of the first assembly . Ideally keep the COM-visible types as thin as possible with the real implementation in a separate .NET assembly . This also means that .NET clients can skip the COM layer entirely .", "Question : If I want to make a .NET assembly usable as a COM server I have to add a set of attributes and then use regasm to register it as a COM server . If the assembly is not signed with a strong name regasm when run with codebase key shows a RA0000 warning saying that the assembly could interfere with other assemblies on the same computer and I should sign it with a strong name but registration succeeds and it even works just fine . AFAIK strong names are intended to prevent so-called DLL hell . But COM was also meant to prevent DLL hell . If I change any interface exposed to COM I must either change the GUID or at least maintain binary compatibility . So signing with a strong name doesn t seem to add anything useful - nothing prevents me from breaking COM interfaces then signing with the same keypair and having full-blown DLL hell . What s the use of signing with as strong name in case of COM-exposed .NET assemblies .. . Answer : To my knowledge COM was not meant to prevent DLL hell it was the pit of Hades itself . The term DLL Hell comes from the problem of multiple libraries each with same-named methods . The registration of COM assemblies in the system registry does not help with resolution at runtime . Signing an assembly that is meant to act as a COM server ensures that the assembly doesn t collide with other COM-registered assemblies on the same computer . Without the signing if two COM-registered assemblies had methods of the same name it could cause problems .", "Question : Why would you need to run regasm and caspol on a .NET component more than once I have a COM client that uses a .NET component residing on another machine . Consequently I need to run regasm and caspol on this .NET component . What could cause there to be the need to do this again on the same machine to the same component Is the effect of regasm and caspol only temporary Or can I assume that someone has reset or cleared something on a machine if I am having to do this again EDIT : Only capsol needs to be run . Comment : A system restore jumps to mind . Comment : What about a different user being logged in Comment : A different user wouldn t matter since the settings are not stored in the per user part of the registry . All COM registration entries are machine specific and I d assume it would be the same for caspol . .. . Answer : I don t know that much about caspol but regasm will write to the registry so the changes should not disappear by themselves I assume caspol is similar . So it does sound like someone else have been messing about with that computer . Possibly this could be affected if someone boots the machine and tells it to use the last known good settings or whatever it s called .", "Question : I m trying to run COM.Scanner https : github.com josephrodriguez miscelaneas.git project but the follow exception is thrown : .. . .. .

You must register the native COM component instead using Regsvr32.exe or preferably the vendor s installer . If you don t have that installer then use a telephone looks like you need to call Zebra . If you did have it then your use of Regasm.exe destroyed the install you ll have to re-install . Comment : If I don t want as requirements to the clients install a SDK I need a native COM component and register it with Regsvr32.exe Comment : Again use a telephone to talk to the vendor and ask for specific-install advice . Asking for a merge module that you can integrate with your own installer is best .

Installing the SDK should solve your issue . Registering the interop assembly does not take you any further as the interop assembly is just a library containing the type definitions of the COM component so that you are able to compile your C code with static-typing and early-binding . The actual thing that needs to be registered is the underlying COM component . To register that you would use regasm.exe only if the actual COM component if the COM component was written in .NET . Otherwise you need to use the classic regsvr32.exe or use the installer of the component vendor . Comment : Let me try with this link @Dirk grateful for your answer and time .

Is there a way of unregistering that dll without putting it back then unregistering then removing the file again And what if I don t have that dll any more or only have one with a different version number .. . Answer : Different version numbers generally do not matter . As long as the newer DLL contains all the GUIDs which appear in the older version it will be unregistered properly using the new one with regasm exe . And of course reregistering the assembly for COM interop will properly relocate necessary registry keys .", "Question : If I want to make a .NET assembly usable as a COM server I have to add a set of attributes and then use regasm to register it as a COM server .

So signing with a strong name doesn t seem to add anything useful - nothing prevents me from breaking COM interfaces then signing with the same keypair and having full-blown DLL hell . What s the use of signing with as strong name in case of COM-exposed .NET assemblies .. . Answer : Strong naming is mainly used to put the Dlls into the GAC . So you can have several versions of the Dll with the same name safely on the same computer which with regular COM-Dlls often produced issues . Not signing the Dlls removes the ability to GAC it . You don t have any immediate problems because of that but you don t use a useful feature so you get a warning .", "Question : I want to know if it s possible to register a type library without using the RegAsm tool http : msdn.microsoft.com en-us library tzat5yw6 28VS.80 29.aspx .

I have successfully registered the assembly and the type library on my development-machine using RegAsm like so : .. . .. . The above command generates the type library MyAssembly.tlb and registers it as well as registering the assembly . I need the type library registered so that I can have Intellisense in VB6 . My problem with this method is that I don t have the same level of control when generating the type library file as I do with TlbExp.exe http : msdn.microsoft.com en-gb library hfzzah2c 28VS.80 29.aspx . In particular I need to use TlbExp s names flag to specify the proper case http : social.msdn.microsoft.com Forums en-US clr thread 5003c486-ed3f-4ec8-8398-a1251b0f9e74 of my property names RegAsm butchers them . So if I use TlbExp to generate my tlb file is there any way that I can register it separately from the assembly registration process Edit : da m n s answer is correct for the question I asked . However I was under the faulty assumption that just because RegAsm could register a type library that it was necessary to register the tlb in order reference it in VB6 . So for now I m registering the assembly and referencing the unregistered TlbExp-generated tlb with the fixed names . Comment : Actually I think I might be mistaken in the assumption that I must register the tlb file in order to reference it in VB6 . Perhaps this question is for nothing . I ll look into it tomorrow . Comment : And now I can t find regtlib.exe on my computer . I can find regtlibv12.exe but no documentation at all . Looks to me like MS is no longer keen on .NET anymore . .. . Answer : Use regtlib.exe to register the tlbexp generated tlb file ." ] }

Blacklist http : en.wikipedia.org wiki Blacklist 5F 28computing 29 : In computing a blacklist is a basic access-control mechanism that allows everyone access except for the members of the black list i.e . list of denied accesses . The opposite is a whitelist which means allow nobody except members of the white list . As a sort of middle ground a greylist contains entries that are temporarily blocked or temporarily allowed . Greylist items may be reviewed or further tested for inclusion in a blacklist or whitelist . Whitelist http : en.wikipedia.org wiki Whitelist : A whitelist or white list is a list or register of entities that for one reason or another are being provided a particular privilege service mobility access or recognition . As a verb to whitelist can mean to authorize access or grant membership . Conversely a blacklist is a list or compilation that identifies entities that are denied unrecognized or ostracized .", "Question : I have been trying to implement a sort of IP blacklisting in PHP where I store failed login attempts to a MySQL table with the following schema : .. . .. .

This way people who simply forget their credentials are affected less than people attempting to brute-force their way into gaining credentials .

Just something to keep in mind . Comment : @h2ooooooo This is true although this would be true of any blacklist if I m not mistaken and feel free to correct me if I am Comment : If we re talking about IP blacklists which is definitely the most safe then you re correct .

I don t think you can avoid the last one really . Comment : I m just a tad hesitant regarding the cron job mainly so that I m not modifying the database when I don t have to granted there could be many wasted deletes anyway . What time range would you suggest Possibly 5 10 minutes For the second query I think you meant release time so as to get still-valid blacklist entries Comment : If you have other cron jobs eg . deleting old inactive accounts you can just lump it in with those and run it on a daily basis . It s worth considering how much traffic failed login attempts per IP we are talking about here. . how many hundreds thousands millions of rows will it take for your failures table to become too slow If we are talking high volumes and persisting these failures forever isn t important you might consider storing the failure list in memory : bookofzeus.com articles http : www.bookofzeus.com articles validate-if-an-ip-is-banned-using-memcached Thanks fixed copy-paste mistake .", "Question : which is the preferred approach in sanitizing inputs coming from the user thank you .. . Answer : As a general rule it s best to use whitelist validation since it s easier to accept only characters you know should go there for example if you have a field where the user inputs his her phone-number you could just do a regex and check that the values received are only numbers drop everything else and just store the numbers . Note that you should proceed to validate the resulting numbers as well . Blacklist validation is weaker because a skilled attacker could evade your validation functions or send values that your function did not expect from OWASP Sanitize with Blacklist : .. . .. . Eliminate or translate characters such as to HTML entities or to remove quotes in an effort to make the input safe . Like blacklists this approach requires maintenance and is usually incomplete . As most fields have a particular grammar it is simpler faster and more secure to simply validate a single correct positive test than to try to include complex and slow sanitization routines for all current and future attacks . Realize that this validation is just a first front defense against attacks . For XSS you should always Escape your output so you can print any character s needed but they are escaped meaning that they are changed to their HTML entity and thus the browser knows it s data and not something that the parser should interpret thus effectively shutting down all XSS attacks . For SQL injections escape all data before storing it try to never use dynamic queries as they are the easiest type of query to exploit . Try to use parameterized store procedures . Also remember to use connections relevant to what the connection has to do . If the connection only needs to read data create a db account with only Read privileges this depends mostly on the roles of the users .

I know there are a ton of issues with blacklist-based filtering but the decision was made above my head . Challenge : I m looking for a good list of Spanish profanity to run into the filter . For English we re building on a list which exhaustively lists conjugations plurals etc one per line of a text file . Does such a list exist in the public domain for Spanish .. . Answer : Finding good lists and having them tuned is difficult . It also sounds like you are doing a lot of manual work that can be automated i.e . conjugation . I did a lot of this for my company s profanity filter named CleanSpeak http : www.inversoft.com features profanity-filter and much of this can be automated using POS identifiers for words and in many cases you can manually do POS tagging or find a POS source . You ll also need to consider the quality of the lists and the up-keep and management of a filter . A lot of people think it is simple and then realize that it is extremely difficult to prevent false-positives . All that said we found the majority of our lists for other languages difficult to come by online and ended up paying to have many of the built or purchased from other companies . The lists we did find online ended up being nearly worthless once we had them translated . We also attempted to take out blacklist and have that translated which was a complete failure because most English profanities don t have equivalents in other languages . I would suggest purchasing lists or working with students at your local university to generate lists . A number of our customers found this method relatively good and not overly expensive . I would also suggest that you take a look at some of the resources out there that define the best ways to manage User Generated Content . These will help guide you through any build vs . buy decisions . Comment : POS Point of Sale Comment : POS Part of Speech .

I do not know how its related to programming so forgive me if I placed the question at wrong place. . .. . Answer : White lists and black lists are two ways of filtering data . If you have a white list then you will filter in only data on the white list if you have a black list you will filter out only data on that list . For example consider automatically rejecting incoming phone calls . You could have a black list of marketing companies so everyone but them would be able to call you . Or you could have white list containing your friends numbers so only they would be able to call you . TL DR : .. . .. . Whitelist - only these things . Blacklist - everything but these things .", "Question : Our mail-server has been blacklisted by lashback.com because Sender has sent to LashBack Unsubscribe Probe accounts but we haven t hosted any mailing lists for years . Our server responds to such requests whether legitimate or merely Lashback probes as undelivered mail see log fragment below . Is that the wrong behavior If so what is the correct behavior Well over a year ago we removed mailman from our server altogether which was long after we ceased to operate any mailing lists . According to its website Lashback s blacklist is developed from a number of tests including the following that appear to be possibly relevant : .. . .. . Which senders fail to provide a working unsubscribe mechanism .. . Which senders do not honor unsubscribe requests within 10 business days .. . .. . I have tried to contact lashback.com by phone and e-mail without success . Phone calls are answered by a robot literally that suggests an e-mail address . When I sent a message to it asking for information as to the correct behavior my message blocked by Google Groups as bulk-email . I guess this was because our mail-server is blacklisted by lashback we know of no other blacklistings of our server and my message didn t look any more like bulk e-mail than this StackOverflow question does . The only prompt remedy available from Lashback is to use their free offer to remove our server from their blacklist once per month but will not solve the problem and we can t afford to do that every month . Lashback asks a significant monthly fee for any other service . I wonder . Is Lashback actually a scam Or are they just having a Very Bad Day with their systems Here is a possibly-relevant fragment of our server s mail log . It might be from Lashback s probe account . We don t get much mail to this long-defunct mailing list . As far as I can tell Postfix tries to send it to mailman but there is no mailman any more and eventually Postfix gives up and sends a nondelivery notice which causes LashBack to blacklist us . .. . Answer : This question has become academic because the real problem was that the server on the LashBack blacklist was not actually ours When our registrar discovered the problem our server s reputation at mxtoolbox.com was immediately restored . The source of the problem turned out to be one of a series of unfortunate system glitches that occurred when we started using our registrar s default name service . Prior to that we had been using free name service which worked perfectly until the presumably-automatic switchover when the glitches occurred . There is no substitute for dig or for careful attention to its output or for actually seeing the surprises that may be in that output .", "Question : Not finding much any info on this subject so thought I would go ahead and post a question .

I came across these terms called whitelist data and blacklist data I tried to find out on google but couldn t . . I do not know how its related to programming so forgive me if I placed the question at wrong place. . .. . Answer : Bruce Schneider has an excellent explanation of black-list vs . white-list in context of computer security : https : www.schneier.com blog archives 2011 01 whitelisting vs.html . Physical security works generally on a whitelist model : if you have a key you can open the door if you know the combination you can open the lock . We do it this way not because it s easier -- although it is generally much easier to make a list of people who should be allowed through your office door than a list of people who shouldn t--but because it s a security system that can be implemented automatically without people . .. . To find blacklists in the real world you have to start looking at environments where almost everyone is allowed . Casinos are a good example : everyone can come in and gamble except those few specifically listed in the casino s black book or the more general Griffin book . Some retail stores have the same model -- a Google search on banned from Wal-Mart results in 1.5 million hits including Megan Fox -- although you have to wonder about enforcement .

Answer : Nuget is likely adding the schema file to the project referencing your Core project . You can reference the same xsd file by adding it as a link-to the referring project . Right-click the non-core project select Add Existing item . Browse to the xsd file - and this bit is key - instead of clicking Add click the little arrow next to Add and select Add as link . Comment : I don t want to do that if there s a way to import the xsd namespace without importing the xsd . E.g . I can import Core.Namespace without having to do anything more than reference the project . Is this how nuget packages achieve this Comment : Hmm . Try deleting the Root namespace in the project properties tab of the core module if there is one . Then add a reference and try importing the namespace . You can try starting with Global . or use the Object Browser in the IDE F2 key Comment : It appears that you were correct that I would need to link-to the file in order to import the namespace from the xsd . I updated your answer to reflect my situation-- the nuget-package did in fact add the xsd directly to the project which is why I was able to import that namespace . I added a bounty then found the file in my project-- I ll give you the bounty as soon as my waiting period is over . Comment : Glad I could help . Thanks for the bounty . Happy programming : -" ] }

Mountain Lion is now Golden Master as I m writing this question so it could be considered as final version . That cannot be said about Xcode that is a preview release yet . RVM recommends to install osx-gcc-installer over Xcode but I would like not to mess my system . What is the cleanest way to install Ruby 1.9.3 on Mountain Lion without Xcode .. . Answer : osx-gcc-installer turns out to be a very good option to replace Xcode in order to install Ruby 1.9.3 .. . .. . These are the steps I have followed : .. . .. . 1 . Download install the latest version of osx-gcc-installer here GCC-10.7-v2 is fine : https : github.com kennethreitz osx-gcc-installer .. . 2 . Install RVM as usual and select 1.9.3-head as the default ruby installation : https : rvm.io rvm install .. . 3 . Install Homebrew : https : github.com mxcl homebrew wiki installation .. . 4 . Install libksba to resolve some dependencies with Ruby 1.9.3 : brew install libksba .. . .. . That s it You should now have Ruby 1.9.3 installed on Mountain Lion working perfectly . If you need some other packages install them now through Homebrew such as Imagemagick for example : brew install imagemagick .. . .. . It s possible that you need XQuartz for Homebrew to work properly as Apple is not shipping X11 since Mountain Lion . You can download it here : http : xquartz.macosforge.org trac wiki .. . .. . EDIT : .. . .. . Now since 29th July Command line tools for Xcode 4.4 are available . So the new steps are these : .. . .. . 1 . Download install Command line tools for Xcode 4.4 you don t need to download Xcode : https : developer.apple.com downloads index.action .. . 2 . Install Homebrew : https : github.com mxcl homebrew wiki installation .. . 3 . Install automake : brew install automake .. . 4 . Install RVM as usual and select 1.9.3-head as the default ruby installation : https : rvm.io rvm install .. . .. . Optional step : You may need XQuartz for some components for example for Imagemagick so download install XQuartz : http : xquartz.macosforge.org trac wiki Comment : I needed XQuartz too for fink and MacPorts well not need but it was checked in the configs . XQuartz seems to work fine under Mountain Lion . Comment : brew install automake doesn t work anymore Comment : @holyredbeard brew install automake installed fine for me on Mountain Lion .

But the jar file was not actually be modified by this command no date file size or binary content was changed . 2 . Export Apple certificate to p12 and use jarsigner . I exported Apple Root CA Apple Timestamp Certification Authority and Developer ID Application : MyCompany to p12 and sign my jar in a common way . 3 . Import my thawte certificate to Mac Keychain Access and export both Apple and thawte certificates to p12 . All three ways give me nothing . When I open a page with the applet Gatekeeper still says that it could not be verified . Could anybody provide me with step by step instructions on how to sign my applet .. . Answer : This may be a bit late for you but in case it helps anyone else : it is possible to bundle the JAR file along with the Java Runtime Environment into a .app . You can then sign the .app using your Apple certificate just as-if you had written in with xcode . Search for javapackager which is just one of many ways to do this . In theory you can even submit such an app to the app-store .", "Question : I have a Java Web Start application which I ve tested on Windows 7 Linux and Mac OS X 10.7 works fine on all .

The compiler and linker are capable of using features and performing optimizations that do not work on older OS versions . -mmacosx-version-min tells the tools what OS versions you need to work with so the tools can disable optimizations that won t run on those OS versions .

Answer : This is because of a new feature in Mountain Lion known as Gatekeeper . Following is a brief description : .. . .. . Choose where apps are installed from : Gatekeeper gives you three security options for downloading and installing apps for your Mac . You can download and install apps from anywhere with the same protection that OS X Lion provides . For maximum security choose to allow only apps from the Mac App Store to be installed . Or download and install apps from the Mac App Store and apps that have been signed with a Developer ID . Gatekeeper alert : Mountain Lion alerts you if you download and try to install an application from a developer who does not have a Developer ID . Manual override : If you receive an alert that an app is from an unidentified developer you can still choose to install it . Control-click the installer or the application icon to reveal a contextual menu . Choose Open and you ll see a dialog that allows you to install the application .

Answer : You should be able to use aElement.click to simulate a mouse click on the link triggering any attached events as well as the default behaviour .

The only downside now is that there will be a small delay after clicking the link while the script is fetched and parsed . You may want to change the mouse cursor to a loading icon or something just in case . Or you could abandon the idea altogether and load the script normally .

HTMLElement.click - MDN https : developer.mozilla.org en-US docs Web API HTMLElement.click Comment : Alas this does not work . If one also adds the statement anchor instance.href https : platform.twitter.com widgets.js to the function defined in this answer then a click does indeed trigger a reaction but there are two problems with the reaction : 1 The reaction is to open a full web page that replaces my site s web page in the browser -- not a pop-up window 2 the new page does not pick up the data-url value from the anchor tag . The tweet dialog has no data in it at all . Comment : Oops . Wrong href in comment above . Should be anchor instance.href https : twitter.com share -- this doesn t make it work either . Comment : @IronPillow take a look at my edit and see if that helps . Comment : Thank you Andy but this didn t solve the problem . The Twitter page still replaces the existing browser page and does not include the field values from the anchor tag . I am going to abandon this approach and use an iframe instead . I very much appreciate the efforts you made .", "Question : I m currently working on a button like the Facebook like and Twitter buttons . Since it will be a bit more complex involving a tooltip that is shown after a click on the button I cannot place it into an iframe . So I thought a bit about why everyone puts their buttons into an iframe . The first thing that came to my mind was that it makes it impossible to alter the appearance of the button . But are there any other security concerns that matter in this case .. . Answer : I suppose it indeed prevents easy tampering with the appearance but also with the behavior all kinds of Javascript i.e . it allows for easier statistics collection and it s probably an easy way to have it implemented widely .

There are those that suggest that HTML5 will one day supplant replace Adobe Flash . I do not develop software that runs in a browser so my limited understanding is : .. . .. . HTML is a pure-text markup language that is delivered over HTTP to a client browser . The client browser interprets the markup and renders with varying degrees of success the page according to an standard specification . Adobe Flash is a propriety framework for working with audio video sound and raster vector-graphics . It requires special authoring tools a compiler perhaps and a custom player that s available as a plug-in to most common browsers . Could someone please explain to this C C++ developer how it is possible from a technical coding point-of-view that a text-based markup language HTML5 could be considered a replacement to a multimedia framework Flash Please no opinionated arguments - just technical facts . Comment : Note that HTML hasn t been as static as you described it for quite some time already . While HTML5 takes it to a new level normal HTML already could do some interesting effects with CSS+JS . Comment : They ve been saying this for years and trying to standardize the standards of the web for more years yet nothing seems to change . Flash and Silverlight solves the cross-browser incompatibility problem better than anything else so far . Not quite cross-platform but a standard cross-browser platform is certainly better than no standard platform at all . Meanwhile the number of competing browsers seems to be increasing making standardization via vendor dev discipline hah even less likely to work . A back-compatible software virtual-machine approach like Flash or Silverlight just works . Comment : Instead of trying to eliminate plugins it s a shame the HTML5 people aren t working on standardizing and improving plugin support . If the browser could be transformed into a platform delivery system instead of a content delivery system we could have many competing and to users entirely transparent and auto-installing web platforms such as Flash Silverlight JavaFX and of course various legacy web HTML renderers . This would solve all cross-browser and backwards-compatibility issues immediately by putting the platform under the control of a single platform developer . Oh well. . Comment : The term html5 usually refers to webapps with HTML5 JavaScript APIs which include databases networking messaging storage as well as Graphics animations and effects with CSS and DOM manipulation . Not to speak of technologies like canvas svg sprites picture transformations gui controls and so on . .. . Answer : how it is possible from a technical coding point-of-view that a text-based markup language HTML5 could be considered a replacement to a multimedia framework Flash HTML5 is the new hot name for web technologies stack not just a markup language . It has a programming language JavaScript like Flash does a set of APIs significantly expanding as part of the efforts commonly labeled as HTML5 ways to draw graphics SVG canvas play audio and video audio video . Unlike Flash the HTML5 applications are processed by the browser not by a proprietary browser-plugin which is good - at least for browser vendors see the relevant piece of this blog post http : daringfireball.net 2010 01 apple adobe flash - thanks Jotham . For example it makes possible for a browser vendor to fix issues and not wait for Adobe -- IIRC Apple cited Flash as being 1 reason for crashes among all crashes on the Mac . edited to remove open standards are better claims which I am too lazy to back up Comment : By way of adding some additional detail to the claim regarding Flash crashes on Mac OS . daringfireball.net 2010 01 apple adobe flash http : daringfireball.net 2010 01 apple adobe flash Comment : are processed by the browser not by a proprietary browser-plugin which is good . how so we have so many browsers that currently seem to render a page differently . At least with Flash there is one consistent environment to develop for . Open standards are also better than a single monopolist implementation . this depends . Open standards work great in theory but is terrible for advancing technology . Just look at OpenGL vs DirectX . Comment : @Allan The reason why browsers used to render pages differently was because the W3C was largely open to interpretation and in particular Microsoft was lousy at following the spec . Open standards are far better than a single implementation - but only when they are clearly defined . Comment : @Antony - you missed my point . I am certainly not saying OpenGL is a redundant technology far from it . My point is proprietary technology more often than not is the driving force for advancing technology . DirectX pulled away from OpenGL and it has been playing catch up ever since . tomshardware.com reviews opengl-directx 2019.html http : www.tomshardware.com reviews opengl-directx 2019.html If it was not for flash the past 10+ years we would have been without streaming video youtube and complex interactive media . Whats more is flash will continually keep improving . Without proprietary technologies we will advance at a snails pace . Comment : @Luka Ramishvili - true but it was not like OpenGL did not work on Windows . The hugely popular Quake 2 engine came out with either software or opengl rendering . Only later around the time of Half-Life did they then add DirectX support . I think it was just that Microsoft had money to throw at developing DirectX at a faster rate", "Question : A topic of debate that s seen a resurgence since the unveiling of the iPad is the issue of Flash versus HTML5 .

Comment : The term html5 usually refers to webapps with HTML5 JavaScript APIs which include databases networking messaging storage as well as Graphics animations and effects with CSS and DOM manipulation .

It is more that the HTML5 stack including JavaScript and CSS can be used to build the same sort of rich web-applications for which Flash was the only viable option before . Because HTML holds the promise to also address some of the shortcoming of the Flash platform there is a potential that it can replace Flash in this space in the future . This discussion is very much centered around the technology that is used to render the application at the users end . It does not address the ease with which authors are actually able to create the content which will be delivered to their users . You already mentioned that Flash is associated with a set of commercial tools which are specifically built and marketed by Adobe to address the need of rich-content authors . Such solutions for HTML5 are not that much adopted yet . For developers who view authoring mostly as coding this is not a big concern and they will not have a hard time getting traction with HTML5 and many already do . For those authors that don t have a developer coding background this may be another story and for them the viability of HTML5 will greatly depend upon the availability of integrated authoring tools . Maybe the Adobe Flash tools will output to HTML5 instead of SWF in a few years.. .", "Question : A topic of debate that s seen a resurgence since the unveiling of the iPad is the issue of Flash versus HTML5 .

Answer : The modern browser that support HTML5 standard http : en.wikipedia.org wiki HTML5 Differences from HTML 4.01.2FXHTML 1.x have capability to playing supported media file inside the browser without needing 3rd party plugins . You can try this by yourself . Latest version of Safary and Google Chrome Firefox 3.6 too can play video tag in a HTML5 page directly . YouTube now support HTML5 http : youtube-global.blogspot.com 2010 01 introducing-youtube-html5-supported.html . That s why iPad will be able to play video if the video site is using HTML5 without Adobe Flash plugins using Safari browser that fully comply the HTML5 standard . Comment : Apple s choice of allowed media convetions processing on its devices has nothing to do with HTML5 .

Answer : Flash operates with a timeline stage and scenes and allows loading of movies one on top of another . It also has onion skinning tweening and other vector art tools that make cartoon animations easy via frame by frame animation . You do all of this and then control it will a very small easy amount of code action script . HTML JAVA CSS isn t anywhere as near an artistic experience for the author and there s much more coding involved to achieve similar results - flash is much quicker and easier and user friendly .

Comment : The term html5 usually refers to webapps with HTML5 JavaScript APIs which include databases networking messaging storage as well as Graphics animations and effects with CSS and DOM manipulation . Not to speak of technologies like canvas svg sprites picture transformations gui controls and so on . .. . Answer : A scathingly obvious and wider angle point that is rarely made is that the vaguely referenced flash term actually encompasses the entire Flash Platform and that includes the Flash IDE . Animators and other artistic types who use the technology to create complex cartoons and animations depend almost entirely on the IDE for their work . It is just simply not possible without it . End of story . It s not just the technology at the language specification level that matters It s also about the supporting technologies in this case IDEs I say supporting but the Flash IDE is very much a technology integrated with the rest of the Flash Platform . If someone builds an HTML5 IDE that has features that rival the Flash IDE that s great but I m surprised the point is so rarely made . Artists are as much part of the debate as programmers and it s unreasonable to say it is not their business . So to answer your question directly : HTML5 would be considered a totally reasonable alternative - or even replacement - to a multimedia framework such as Flash if and only if a proper IDE is built for it thus elevating it to a multimedia framework also . It is just not realistic to make an argument without taking into account IDEs . If the question is specifically Can HTML5 in it s completed state without an IDE be an alternative to Flash for applications apart from manually animated complex animations then the answer would most likely be yes and we d all go home .

Answer : It is possible the text-based markup language HTML5 could replace a multimedia framework Flash . The solution is simple just move the framework into the browser and become an open standard .

Comment : Well what animation software have you used before Can it not output videos then on your site you simply use Javascript to control the playback of animations per click .

However if you look around the web nowadays you ll see that Flash is in widespread use for delivering video or audio content in the browser . Something that s included in HTML 5 albeit crippled by now since they couldn t agree on any standard codecs . Surely all those nice Flash games and ads won t go away just because of HTML 5 and HTML 5 won t be able to replace them . But it aims for being able to replace uses that actually can deliver content . For vector-graphics there is also SVG which might get some special treatment . Whether this will really be the death of Flash for video remains to be seen . The HTML 5 video codec issues might be sorted out sooner or later . However Flash will quite likely remain the medium of choice where content deliverers will want greater control over what will be delivered DRM and similar techniques c .", "Question : A topic of debate that s seen a resurgence since the unveiling of the iPad is the issue of Flash versus HTML5 .

I echo the sentiment of most posters here that while HTML 5 makes great leaps in basic multimedia presentation it won t be able to replace Flash . All the online gaming sites are a good example . Flash is can run on most browsers except on certain mobile-devices . On that note I believe battery drain was the original reason why Steve Jobs did not want to support Flash on the iPhone and iPad . This might bite Apple no pun down the road . Android 2.2 will have flash support but it not clear if all the hardware manufactures will support it -they ll have be confident in their batteries . Also it looks like Flash 10+ will be a sure thing on Blackberry devices going forward including BB phones the upcoming BB Playbook tablet btw this toy has some killer specs - can t wait to get my hands on it when it comes out next year . I am willing to bet that Flash will continue to be big in Web Dev even after HTML 5 support becomes universal .", "Question : A topic of debate that s seen a resurgence since the unveiling of the iPad is the issue of Flash versus HTML5 .

Answer : I sure hope that HTML5 can deliver the goods and maybe not replace flash entirely but at least when it comes to video .

And the problem is not only that HTML5 is limited in amount of required in an app UI components but also that it doesn t allow create custom ones in such a way that they would integrate into runtime seamlessly .

He hates Flash perhaps because it crashes on his Mac computers I m not sure . I think he s out of touch . The proof is his ridiculous product the iPad . The point is HOW GOOD IS IT FOR DEVELOPERS Answer : not as good as Flash . Yet . Why do I say this with my limited experience It s all that try.. . catch compatibility code you need in Javascript to work in all the browsers . WHAT A LOAD OF RUBBISH . ActionScript Flash is ONE piece of code app for ALL browsers . The other thing Flash has is graphical and non-graphical development software tools to streamline the process . So THE SHORT ANSWER IS THAT ADOBE WON T LET HTML5 replace flash at least for the short term . But it can compete with Flash if people make enough development tools for it particularly WYSIWYG graphical tools like if Google develop an easy to use WYSIWYG editor for making GWT apps .

Answer : We are currently developing an LCMS once of the areas is a fully WYSIWYG authoring tool for the development of SCORM and AICC compliant training materials that contain animation video audio multiple types of assessments with interaction . The tool looks close to how a power point looks allowing the user to easily drag-and-drop learning objects to the slide with pictures resize images move them overlap text add the tests etc . This workspace is done currently in Flex and has great performance not even Google Docs Presentations comes close to the flexibility and performance of this application .

Answer : Together with javascripts for tracking GUI events and scripting of the new HTML 5 elements you get a lot of what Flash offers . HTML 5 has a number of new elements . One of them is called Canvas . With it you can draw anything you want on screen within its bounds . You use javascript to draw on it and you can catch any mouseclicks and similar with javascript too . If you are used to GUI toolkits on the desktop like Tk GTK you can liken these new elements to some of the widgets of those GUI toolkits .

Browsers do not allow AJAX requests to another domain if you try to use the form on the site app.icontact.com or maybe icontact.com it will work . If you cannot use icontact.com for the form then I suggest you write a PHP code which is the server-side language in our case to process jsonp . This is a workaround for cross-origin policy . Add dataType : jsonp to .ajax .. . .. . Executing the above code gave me a syntax-error from signup.php so I am assuming processing the jsonp correctly will get you the success alert .", "Question : I am playing around with iContact API and am running into an issue .

Answer : As Anton http : stackoverflow.com users 2097228 anton specified in his answer http : stackoverflow.com a 29791126 1544364 OSGi console indeed solves the problem .

Including Windows own msconfig.exe Comment : Thank you.. . if you do both the registry key and the startup I assuming you will you have 2 instances running . Is there a good way to prevent that Comment : Hmm so does creating more than one shortcut and creating more than one registry key . My doctor s usual advice fits here : if it hurts then don t do it . Comment : There is no fundamental difference in what it accomplishes there are however definite concerns on which one to pick . I prefer the Startup folder because you can create a shortcut for a specific user not everyone who logs onto a machine wants your app to run automatically . Adding to the Startup folder also doesn t require your app or installer to run with elevated admin privileges where writing to the registry does . Knowing this is useful if you provide the option to run at startup from within your application which may not be running elevated and won t allow a registry modification .

The portal and Portlets are deployed in a JBoss 5 server . Right now the server itself takes anywhere between 15 - 20 mins to start . I am trying to see if I can tweak the JBoss configuration to deploy multiple WAR files at the same time . Is that a good option Are there any other ways to improve the startup time .. . Answer : Of course that the portal startup time depends the number of deployed portlets even though 15 minutes to deploy 20 portlets I think it is excessive . I ve never used JBoss as application server but with Tomcat the startup speed depends basically of two things : .. . .. . The number of deployed portlets : The more portlets deployed more time gets the portal to be started . The memory allocated : The more memory allocated to the application server less time to start the portal . There can be something more to check but at least for me these are the most important causes . As you probably can not reduce the number of portlets you ll have to try to increase the memory allocated to JBoss .", "Question : Question : .. . .. . In .NET do you have any criteria that qualifies a certain form to be the startup form Example : .. . .. . For example if I have a basic calculator program and it has 3 forms namely frmConfig frmCalculator and frmProfile . frmConfig - The settings page includes whether I should automatically round off or out put the whole decimals etc . frmCalculator - The main page the calculator itself where you can do all the calculations that you want . frmProfile - The login page you can see the history of your calculations here . Notes : .. . .. . 1 . From that 3 different kinds of forms how do I properly choose the startup form 2 . Does it mean that the startup form should always be the first form to see when the application is running Because for example I can make the frmConfig as the startup form then on OnLoad event of it it will hide itself then open the frmCalculator because frmCalculator depends on frmConfig s default setting . .. . .. . 3 . To make this question not broad I am looking for the most common way of setting up the startup form maybe there is a standard way Comment : You can also start the app from a Sub Main . Since you describe frmCalculator as The main page it seems logical to use that as the MainForm or for the app msg pump . My most common way is Sub Main so the app can do whatever it needs to before any form shows . .. . Answer : You can set your startup form by accessing the My Project from the Solution Explorer then going to the Application page .. . .. .

The RunOnce key is just for programs that you want to as the name implies run only once . The registry entry is automatically removed from RunOnce after the OS starts .

What I am going to do is use in-app-purchase to unlock an iPad interface and then display the correct interface using conditionals . If the interface is purchased the app displays the iPad Nib and if not it just displays the same way as an iPhone application does with the option to scale the app etc . The conditionals are very simple and I have already implemented them however the issue I run into is this : If the IAP is NOT purchased the iPad displays the iPhone Nib but not in the typical way . It is just in the corner with no option to scale it rather than in the center with the black border that you usually see . Does anyone know how I can set it up so i fixes this issue I m a little stumped to be honest . Comment : I don t think there is a way to achieve what you are trying to do . The iPad s OS determines what kind of app it is running iPad compatible or iPhone resolution and presents the view accordingly . If you tell the OS through the app configuration that it can run on iPad you will always get that kind of view . Unless you do the view scaling manually on your own . .. . Answer : This isn t possible unfortunately . The iPad will know that the app is iPad ready and will tell draw the screen at full size . Even if you showed iPhone xib file on the iPad they would still be scaled to fit the full screen using the UIViewAutoresizingMask params you ve set for them . One thought would be to force the size of your UIWindow to be iPhone sized remember to account for retina and centered but I m not 100 sure how if this would work .

Answer : Creating Universal App Using Storyboard .. . .. . When you first create a Xcode project you re provided with an option to define the supported devices . Choose Universal and Xcode will automatically create a project for all iOS devices .", "Question : When creating a storyboard file in Xcode you must select if it is for iPhone or iPad . This implies one should always put iPhone and iPad UIs into separate storyboards . Is this true My app has multiple storyboards . While the Main.storyboard files largely differ between iPhone and iPad other storyboards are nearly identical . The only difference might be segue being a push on iPhone vs popover on iPad which can be handled programmatically . It seems awfully silly and redundant to make two storyboards . So if making one universal-storyboard should iPhone or iPad be selected in Xcode Does it matter Comment : You do need to separate storyboards however you can very easily copy all your objects from one storyboard to the other and then adjust only the small differences . All your outlets and segue will stay there you would just need to drag outlets to classes but this is fast . .. . Answer : As of Xcode 6 we can create a single unified storyboard for all the devices . For more info - Documentation https : developer.apple.com library prerelease ios releasenotes General WhatsNewIniOS Articles iOS8.html apple ref doc uid TP40014205-SW1 .. . .. . iOS 8 makes dealing with screen-size and orientation much more versatile . It is easier than ever to create a single interface for your app that works well on both iPad and iPhone adjusting to orientation-changes and different screen sizes as needed . Design apps with a common interface and then customize them for different size classes . Adapt your user-interface to the strengths of each form factor . You no longer need to create a specific iPad storyboard instead target the appropriate size classes and tune your interface for the best experience . .. . There are two types of size classes in iOS 8 : regular and compact . A regular size class denotes either a large amount of screen space such as on an iPad or a commonly adopted paradigm that provides the illusion of a large amount of screen space such as scrolling on an iPhone . Every device is defined by a size class both vertically and horizontally . iPad size classes shows the native size classes for the iPad . With the amount of screen space available the iPad has a regular size class in the vertical and horizontal directions in both portrait and landscape orientations .

I m thinking of to create separate storyboards for iPhone and iPad . Is there any proper way to achieve this .. . Answer : If you are deploying your App to iOS 8 only then I would use one storyboard . It is simpler to utilize one screen . Here is a link for a great tutorial . http : www.raywenderlich.com 83276 beginning-adaptive-layout-tutorial .. . If you are like me and want to target down to iOS 6 then I would use separate storyboards . Definitely stick with Auto Layout for whatever you decide to use .

Or do I need to create a new view or storyboard for iPad and one for iPhone I have no clue how to start at this moment . .. . Answer : You only need one storyboard to build an interface that is compatible with both iPad and iPhone models . Apple is now encouraging developers to embrace Adaptive User Interfaces . As their guide https : developer.apple.com design adaptivity states With the latest advancements with View Controllers in iOS 8 and Auto Layout in Xcode it s now even easier for you to adapt your user-interface to context and different sized devices . In other words you only need a single storyboard for all iOS devices also known as a Universal storyboard . This tutorial http : www.raywenderlich.com 83276 beginning-adaptive-layout-tutorial should get you started with Universal Storyboards and adaptive-layout . Comment : Thanks for your help . I am reading your tutorial and it s awesome Comment : My pleasure Not my tutorial though---just one I found very helpful :", "Question : I am developing a cocos2d game . I need to make it universal . Problem is that I want to use minimun amount of images to keep the universal-binary as small as possible . Is there any possibility that I can use same images I am using for iphone retina and iPad somehow If yes how can I do that What image-size and quality should it be Any suggestion Thanks and Best regards .. . Answer : There s not a single right answer to this question . One way to do it is to create images that are larger than you need and then scale them down . If the images don t have a lot of fine detail that should work pretty well . As an example this is the reason that you submit a 512x512 pixel image of your app icon along with your app to the App Store . Apple never displays the image at that size but uses it to create a variety of smaller sizes for display in the App Store . Another approach is to use vector images which you can draw perfectly at any size that you need . Unfortunately the only vector format that I can think of that s supported in iOS is PDF .", "Question : I have a project for iPhone and iPad . The iPad needs a split view controller . Do we create two separate storyboards One for iPhone using autolayout we can support all devices and two for iPad . My doubt is the difference it only in initial view . The inside views repeats . How will be your approach with storyboard .. . Answer : For iOS 7 and before yes use two storyboards and two completely different interfaces since there is no split view controller on the iPhone . For iOS 8 use one storyboard and use the UISplitViewController on both the iPad and the iPhone . Make a new project from the Universal version of the Xcode 6 Master-Detail app template to see all about how it works It is automatically a split view controller on the iPad and a navigation interface on the iPhone . Comment : And here s my example showing how to construct the whole thing for iOS 8 in code if you don t want to use the storyboard : github.com mattneub Programming-iOS-Book-Examples tree master https : github.com mattneub Programming-iOS-Book-Examples tree master bk2ch09p488basicMasterDetail MasterDetail", "Question : I am developing a cocos2d game .

Is there any possibility that I can use same images I am using for iphone retina and iPad somehow If yes how can I do that What image-size and quality should it be Any suggestion Thanks and Best regards .. . Answer : As for suggestions : provide HD resolution images for Retina devices and iPad provide SD resolution images for non-Retina devices . Don t think about an all-in-one solution - there isn t one that s acceptable . 1 . Don t upscale SD images to HD resolution on Retina devices or iPad . It won t look any better . 2 . Don t downscale HD images for non-Retina devices . Your textures will still use 4x the memory on devices that have half or even a quarter of the memory available . In addition downscaling images is bad for performance because it has to be done by the CPU on older devices . While you could downscale the image and save the downscaled texture it adds a lot more complexity to your code and will increase the loading time . Comment : Thanks . My confusion is now gone after this answer .", "Question : I have a simple app where the UI is created using storyboard . I have a login screen with an icon and a login button . It is showing up when I run on iPhone but on iPad . Both in simulator and on device . To check if it was due to my constraints I just dropped one label without any constraints and view with blue background . Even these are not showing up . Build settings has Deployment Info -- Devices set to Universal . Any pointers to what is wrong will be greatly appreciated . EDIT .. . .. . I tried the following . In my app after successful login UI enters a tab-view controller . If I disable the showing of login screen the app is entering the tab view controller and displaying it properly on the iPad too . I have no idea why the login screen is not showing up on the iPad . EDIT to add details requested by Islam .. . .. . Code .. . .. . AppDelegate checks if user is logged in . If no shows the login screen else shows the TabViewOCntrolelr . The TabViewCOntroller part is showing up on the iPad and iPhone .. . .. . ViewCOntroller code does nothing fancy .

I have added the info you have requested as edit . Please let me know if you need anything else . .. . Answer : It seems that you add your views not in wAny hAny mode bottom side in your storyboard . If you add your views in wRegular hRegular for example mode you will see your views only on iPads . And vice-verse .

Answer : That error is being triggered because you didn t weak-link the UIKit framework . The UIKit framework in iPhone OS 3.2 added the UISplitViewController and if you link it in as normal your application will assume those symbols exist on 3.0 where they don t . To weak-link a framework find your application target in Xcode inspect it and go to the General tab . At the bottom of that tab should be a list of frameworks with a column for Type . Change the Type for UIKit from Required to Weak and rebuild your application . That should take care of the runtime errors . Your conditional logic is sound but I tend to share an application delegate and do the interface-specific layout further down the line . Update : 12 21 2011 As of iOS 4.2 you should no longer need to weak link frameworks to prevent errors like this . As Marco Arment describes http : www.marco.org 2010 11 22 supporting-older-versions-of-ios-while-using-new-apis if you build with iOS 4.2 or later and target down to iPhone OS 3.1+ individual classes are now weak linked and should have their +class method return nil if the class does not exist on the currently running version of the OS .

If I try to open the Experience Editor for these pages it either does not open the Editor or it opens the Editor but adding any component causes an error message . For eg : I created a page named t - opened experience-editor - tried to add components - causes error message an error occurred to appear in experience-editor but when I go to Content editor that component is added . Next I tried changing the display name of the item to test and kept item name as it is t - tried to add components in experience-editor - causes same error message to appear in experience-editor but when I go to Content editor that component is added . Next I tried to change item name to tr instead of t and kept display name as test - tried to add components in experience-editor - component is added successfully in experience-editor as well as content editor . As a workaround we can add a string to the item name but I am not able to figure out why is it happening for these letters . Did someone encounter this issue Actually I need to add glossary in my website so i have to create item names by single letters only from A to Z so need help on this .

Answer : How your site configuration looks like Do you have languageEmbedding set to asNeeded If the answer is yes - try to change it to never or always . This behavior occurs because sitecore tries to find language in your url . There is also another options - do you use wildcards inside your structure sometimes experience-editor can t decide - load wildcard or item from structure . The solution is move wildcard into other directory . Comment : Hi there are no wildcards in my structure . Also this issue is occurring on pre-prod and prod environments . It is not occurring on my local machine and development-environment . I compared config files of all the environments there are no changes related to languageEmbedding property . The setting is same across all the environments . Is there any other property which i can check Comment : @NatashaBatra well in this situation I probably would do following steps : 1 open a browser console in experience-editor view 2 check ajax request made by experience-editor if error occured - there should be visible description 3 if error wouldn t say nothing to you please copy-paste it here", "Question : null .. .

We are using the master DB when in experience-editor Comment : @Jihyun if I remove a component and save it works fine .. . Answer : I ve noticed that this can be caused by having Final Renderings set on a template s standard values . Currently I can t think of a reason to do this but I can see how it s very easy to accidentally edit a standard values item in the experience-editor in the wrong mode . It s easy to reset presentation details back to standard values in Sitecore but to my knowledge you can t reset just the final renderings . To avoid having to go through each failing template and manually reset and re-add all the added renderings I ve found an easy way to fix it if you have TDS or similar installed . 1 . Search for Final in the Sitecore templates folder in the file system . 2 . Delete all the instances of this Final Renderings field From the ----field---- line until the next one . 3 . Sync with Sitecore .

Answer : Suppose your application named MyApp contains the following components . MyActivity1 .. . MyActivity2 .. . MyActivity3 .. . MyService .. . .. . In order to filter the logging output from your application MyApp using logcat you would type the following . However this requires you to know the TAG names for all of the components in your application rather than filtering using the application name MyApp . See logcat http : developer.android.com tools debugging debugging-log.html for specifics . One solution to allow filtering at the application level would be to add a prefix to each of your unique TAG s . MyAppActivity1 .. . MyAppActivity2 .. . MyAppActivity3 .. . MyAppService .. . .. . Now a wild card filter on the logcat output can be performed using the TAG prefix . The result will be the output from the entire application .

Answer : When it comes to logging on Android I d definitely recommend : https : github.com JakeWharton timber .. . .. . For example you don t need to do that annoying TAG all the time as Timber does this for you . Regarding your question I think what you can do it to plant your own tree in Timber . This will make sure all logging goes through there and from there you can catch and log everything you want . See his example of where the Tree is planted in the Application : https : github.com JakeWharton timber blob master timber-sample src main java com example timber ExampleApp.java Now this is in the Application layer so you would need to fetch them into your activities in some way . A quick way not very beautiful way I think you can do is to store the logs in a Collection and have this statically accessible to fetch from the Application . On a side note I m curious of why you want this why isn t Android Studio s logging tool good enough : Comment : Thank you I ll check that out . Android Studio s logging tool works great but I d also like to be able to view the logs on the device when I m running the app without the computer . It s a network testing app so I log messages when certain things happen in the background and I d like to be able to view a list of those messages . Comment : Hey Brendan sure makes sense . I think Timber will suit your needs . If not another option is to write your own customised logger where you create a Singleton that you can fetch from anywhere and log what you want store the values in a Collection and fetch them from there .", "Question : OK logcat is showing system logs but it is not showing application log on my Huawei Ascend .

I want a way to remove some specific entries rather than isolate them . .. . Answer : Depends on which way you view your logcat . If you are using the GUI logcat interface it s best to create a filter for the tags you want to see . These get dropped into a seperate category .

Is this accurate and if so is there a way to work around this .. . Answer : HTTP servers compliant to HTTP 1.1 are expected to support pipelining . Note that pipelining is supposed to be also supported by client . According to httpserver http : download.oracle.com javase 6 docs jre api net httpserver spec com sun net httpserver package-summary.html .. . .. . The API provides a partial implementation of RFC 2616 HTTP 1.1 and RFC 2818 HTTP over TLS . it seems to imply that the com.sun.net.httpserver.HttpServer does not fully support HTTP1.1 . HttpURLConnection does not support pipelining and so I am leaning to think that the com.sun.net.httpserver.HttpServer does not support pipelining either . You say you did some tests . How did you test this Update : .. . From the note it seems that pipelining is supported . If as you say you send the requests pipelined the responses should come back according to the arrival of the requests irrelevant of time it takes to finish each request i.e . some are faster than others . Comment : I tested it by creating a server that handles two requests one that sleeps and one that doesn t and a pipelined client . Creating two connections do not block each other executed concurrently by the server but a slow followed by a fast request on the same connection results in the fast waiting for the slow to finish . The documentation also adds Any HTTP functionality not provided by this API can be implemented by application code using the API . If you have any ideas on how best to approach this I d be thankful to hear them . Comment : @Brian : If I understand correctly : you are using a pipelined client your implementation and you are sending 2 requests over the same HTTP connection.One slow followed by one fast.I am not sure what you mean here but on pipelining if client send Req1 Req2 to the server then the server is expected to send Response for Req1 followed by Response for Req2 . I.e . the server MUST send the responses to the requests in the same order that the requests were received . So from your description it seems that this is actually happening in your case since the fast request was send after the slow . Comment : I have tracing points in both requests to mark their start time and end times . What I always see is START A END A START B END B . Of course what I d like to see is START A START B END A END B - and this happens if two different connections are issuing A and B but not for the same . Comment : @Brian : Didn t you say that you are using a pipelined client Are you not sending the requests pipelined Can you give more details on the client-side implementation Because your notes seem in contradiction so far .", "Question : Does com.sun.net.httpserver.HttpServer support single-connection pipelining It seems to handle multiple clients in parallel but a single connection s requests are being serially executed . Is this accurate and if so is there a way to work around this .. . Answer : HTTP pipelining means something really simple : client can write next request to the connection without having read the previous response . It s really difficult for any http server to not support pipelining . It has to look ahead and if it finds bytes available beyond current request it needs to abort .. . but that s ridiculous and nobody does it . This has nothing to do with how requests are processed by server - serially or paralleled . Doing it in parallel is of course more difficult and there are some questions that must be resolved . Comment : The question was more in the context of the HttpServer class itself . The registered HttpHandler will be invoked serially for two pipelined requests where for every request a HttpExchange object is given . It appears that it s not the case that two HttpExchanges can be outstanding for a single connection even if the server is careful in responding in proper order . Comment : @Brian per HTTP spec the server is still supporting pipelining even though internally requests are processed serially .", "Question : WWDC 2012 session 706 - Networking Best Practices https : developer.apple.com videos wwdc 2012 id 706 talks about something called HTTP Pipelining http : en.wikipedia.org wiki HTTP pipelining .

The WWDC session described it as a huge performance win if the servers support it . pipelining http : i.stack.imgur.com MbAOA.png .. . Answer : Implementation bugs .. . .. . For pipelining to work responses must come back in the order they were requested . A naive server implementation might just send the response as soon as it has been calculated . If multiple requests are sent in parallel and the first request one takes longer to process e.g . processing a larger image then the responses will be out of order . This is a problem for the client since HTTP is a stateless protocol the client has no way to match the requests with the responses . It is reliant on the order the responses came back in . A server MUST send its responses to those requests in the same order that the requests were received . http : www.w3.org Protocols rfc2616 rfc2616-sec8.html .. . .. .

Susceptible to head of line blocking Comment : can you elaborate why proxy does not support it assuming the server that proxy connects to supports it Comment : @HelinWang - If you think about it the implementation is hard for proxies since it has to send the responses back in the right order . They would also be susceptible to head of line blocking see diagram . The wiki page says Most HTTP proxies do not pipeline outgoing requests . en.wikipedia.org wiki https : en.wikipedia.org wiki HTTP pipelining Implementation in web proxies", "Question : I am trying to understand what are the HTTP pipelining and HTTP keep-alive connections and trying to establish a connection between these two topics and Server Sent events technology . As far as I understand HTTP keep-alive connection is the default in HTTP 1.1 way of using TCP when the established once TCP connection is used for sending several HTTP requests one by one . HTTP pipelining is the capability of client to send requests to server while responses to previous requests were not yet received using the same TCP connection generally not used as a default way in browsers . My questions : .. . .. . 1 if it is possible to send several requests to server one after one using one TCP connection - how the client can distinguish between the responses I guess client is using FIFO order of sending responses by server 2 Why non-idempotent requests such as POST requests shouldn t be pipelined according to wikipedia 3 What about the limitations of the web-server : is the number of possible open TCP connections limited If yes then if some number of clients hold keep-alive connections others cannot establish connections and this can result in a problem right 4 Server Sent Events are using the keep-alive connection but as far as I understand SSE are not using pipelining . Instead they manage to process several responses to one request or may be they just send another request when the next response with event arrived . Which guess is correct 5 One TCP connection means one socket One socket means one TCP connection Closing opening socket means closing opening TCP connection .. . Answer : 1 . Yes FIFO . TCP IP guarantees delivering data in-order so responses can t arrive in a different order if the server proxy is buggy and sends responses in wrong order then you re totally screwed . 2 . I don t recall any reason per HTTP spec . It may be just caution because pipelining is poorly implemented in some proxies servers . 3 . HTTP spec suggests 2 connections per server browsers have settled on 6-8 connections per server but there is no fixed limit . Running out of connections is a real problem for Apache and for high-load situations it s recommended to disable KeepAlive in Apache and use a proxy e.g . HAProxy that can cheaply provide Keep-Alive functionality to clients . The benefit of a proxy is that one proxy can distribute connections to several servers helps scaling or can modify the traffic e.g . gzip compress everything even if server-side-software didn t . 4 . SSE doesn t rely on Keep-Alive . It s not using multiple responses . It s a single response that takes forever to download so pipelining or keep-alive are irrelevant for SSE . The TCP IP connection cannot return any more responses while SSE response is being sent . SSE will keep the server busy as long as the connection is open so typicall all the time for every user . That s why it s best to use SSE with Node.js Tornado that can handle hundreds of thousands connections rather than PHP Apache that is designed for few connections at a time . 5 . Sockets are programming interface for TCP IP connections . Generally yes one socket is one connection . Comment : Thanks porneL 1 But what if some response have arrived in wrong order relative to the sent order 3 What is the benefit of using proxy it has to establish the same connections with server anyway 4 So using SSE implies +1 connection thus raising server loading Comment : @KutaBeach I ve expanded my answer", "Question : To verify that using http-pipelining can optimize the speed of loading resources I made a test as follows : .. . .. .

I got the following figure : .. . .. . enter image description here http : i.stack.imgur.com MLUyJ.png .. . .. .

I suppose the total time of loading will be shortened but unfortunately it s the same with that of no pipelining . So I doubt the pipelining doesn t seem to work . I want to know why and how can I fix it . I use apache server . Are there any configs need to be made in Apache .. . Answer : As wiki http : en.wikipedia.org wiki HTTP pipelining said .. . .. . The pipelining of requests results in a dramatic improvement in the loading times of HTML pages especially over high latency connections such as satellite Internet connections . The speedup is less apparent on broadband connections .. . .. . Your test is based on a typical broadband connection . It is so short a moment can be ignored for the server to receive each request and every time it sends such a big picture whole bandwidth of the connection is occupied . So you can retry your test with : .. . .. . 1 . High latency on each request . 2 . Many tiny files as resources to response .", "Question : I was just reading this Wikipedia article http : en.wikipedia.org wiki HTTP pipelining on HTTP pipelining and from the diagram it appears that responses can be sent concurrently on one connection . Am I misinterpreting the diagram or is this allowed Section 8.1.2.2 of RFC 2616 https : tools.ietf.org html rfc2616 section-8.1.2.2 states : .. . .. . A server MUST send its responses to those requests in the same order that the requests were received . Whilst that stops short of explicitly ruling out concurrent responses it does not mention a need to ensure that responses must not only start in the correct order with relation to requests but also finish in the correct order . I also cannot imagine the practicalities of dealing with concurrent responses - how would the client know to which response the received data applies Therefore my interpretation of the RFC is that whilst additional requests can be made whilst the response to the first request is being processed it is not allowedfor the client to send concurrent requests or the server to send concurrent responses on the same connection . Is this correct I ve attached a diagram below to illustrate my interpretation . It would prevent the problems I mentioned from occurring but it does not appear to completely align with the diagram in Wikipedia . HTTP pipelining http : i.stack.imgur.com gWr51.png .. . Answer : Short answer : Yes clients and servers can send requests and responses concurrently . However a server cannot send multiple responses to one request i.e . the request response pattern still applies . RFC 2616 and the Wikipedia article you are refering to simply state that a client does not need to wait for the server s response to send an additional request on the same connection . So the requests in your diagram look good : . But the server doesn t have to wait for each of its responses to finish before it can start transmission of the next response . It can just send the responses to the client as it receives the client s requests . Which results in the diagram shown in the Wikipedia article . How does the client know to which request a response applies Well let s ignore that whole network delay stuff for a minute here and assume that pipelined request or response messages arrive at once but only after all of them have been sent . 1 . The client sends its requests in a certain order without waiting for responses inbetween requests . 2 . The server receives the requests in the same order TCP guarantees that all at once . 3 . The server takes the first request message processes it and stores the response in a queue . 4 . The server takes the second request message processes it and stores the response in a queue . 5 . You get the idea.. . .. . 6 . The server sends the contents of that queue to the client . The responses are stored in order so the response to the first request is at the beginning of that queue followed by the response to the second request and so on.. . .. . 7 . The client receives the responses in the same order TCP guarantees that and associates the first response with the first request it made and so on . This still works even if we don t assume that we receive all the messages at once because TCP guarantees that the data that was sent is received in the same order . We could also ignore the network completely and just look at the messages that are transferred between server and client . Client - Server .. . .. . Server - Client .. . .. . The great thing about TCP is that this particular stream of messages always looks the same . You can send all of the requests first and then receive the responses you can send request 1 first receive the first response send the remaining requests and receive the remaining responses you can send the first and part of the second request receive part of the first response send the remaining requests receive the remaining responses etc . Because TCP guarantees to keep the order of the transmitted messages we can always associate the first request with the first response and so on . I hope this answers your question.. . Comment : I see - so it s a case of perspective : from the application perspective responses cannot be sent to the buffer concurrently but consecutively . However at the transport layer as TCP is reliable and connection-oriented the requests will arrive in the client s application layer same order as they were sent from the server s application layer - although the individual packets may be sent in a different order . It answers my question though that responses cannot be sent concurrently from the application layer - thanks", "Question : First I have ServiceStack as my server which provides RESTful HTTP API .

Answer : Pipelining is done at a very low-level below IIS even in the http.sys kernel-mode driver .

You can approximate pipelining by using grequests which makes it easier to run many requests in parallel but each parallel request would still use a new TCP connection . requests does pool connections keeping the TCP connection open if the remote-server permits this but that only helps for sequential connections and request and response still have to alternate .", "Question : Is there a specific or agreed upon HTTP response message or another action except for disconnection to clarify that the server does not accept pipelined HTTP requests http : en.wikipedia.org wiki HTTP pipelining I m looking for something that will make the client stop pipelining it s requests and to send each request separately .

My two questions are : .. . .. . 1 . Is the image correct 2 . Is it true that if pipelining would not have the head-of-line blocking problem http : en.wikipedia.org wiki Head-of-line blocking it would be as fast as HTTP multiplexing Or did I miss an additional difference .. . Answer : It s not incorrect but there is an important aspect it omits . HTTP requires that you deliver the entire response before any other request can proceed . What you re showing in the diagram is correct in the sense that with SPDY we can finally break the head of line requirement and deliver the responses as they become available . However we also don t have to wait for any request to complete entirely . Imagine two requests both several kb s in size : each request will have multiple packets call them r1p1 r1p2 and r2p1 r2p2 . HTTP requires that pN s arrive in exact order . SPDY on the other hand allows us the following : r2p1 r1p1 r1p2 r2p2 . It s also worth mentioning that with SPDY we can use request priorities to hint the server which requests should take precedence even if it arrives later on the wire amongst half a dozen other great features .

In C there is a HttpContext https : msdn.microsoft.com en-us library system.web.httpcontext v vs.110 .aspx that facilitates this . The new request comes in on a separate thread which has no safe context of any other requests . When a client makes a request for example via WebRequest https : msdn.microsoft.com en-us library 456dfw4f v vs.110 .aspx the response is tied to that request . Therefore Request1 in your example could never be mixed up with Request2 .

What are you trying to do with the client s IP address As it is sometimes not a good idea to identify a client by its IP address . Comment : I m writing a server application and I would like to accept user requests only if coming from authorized IPs . .. . Answer : You can do this by using the middleware concept of shelf .

An example using the logger can be found here : https : github.com dart-lang shelf .. . .. . In the middleware you can find the ip-address in the request object which extends message .

After a bit of Googling I found out about the API Discovery Service https : developers.google.com discovery which explained how to create client code for a given Discovery Document . I then found Google Cloud Endpoint which looks like the server end of the a Document Discovery service . Is this true . My real question is that I would like to use the Document Discovery service on a standard web site that is based on say Spring and running say an embedded Jetty server Is this possible or would my application be intertwined with the App Engine Technology .. . Answer : You application just needs to provide a Document Discovery service . It shouldn t be to hard to get the information what is expected out of the source of https : pub.dartlang.org packages discovery api client generator which is the Dart client which generates Dart client code from discovery documents . As far as I know your service doesn t even need to provide the discovery documents . The discovery api client generator package can also use discovery documents stored locally but the service is of course the preferred way if you want to make it available to everyone . I would see it as equivalent to SOAP which also allows to create client code from meta-information provided as XML . Also the shelf rpc package doesn t need to run on AppEngine or Managed VM . You can run it locally or on any server you want . Comment : Hi Gunter . In this case this question is not about Dart but about Java - Can I add a Document Discovery service to my existing java Web service application Comment : The discovery document describes the API . I haven t checked but I assume it s JSON . You need to provide such a document for your API in some way and you need a generator that generates code from this document . Such a client exists for various languages including Java . The shelf rpc package generates the discovery document from the classes you use in the API and annotations you add to classes methods and fields . You just have to find or build such a tool for Java I assume there already exists one but haven t checked . Comment : You could also use Protocol Buffers in a similar way . You describe the API in a text document and generate classes for client and server from the document but ProtoBuf is a binary format instead of JSON .", "Question : Using dart-rpc can you label a API method as async I see in the documentation you can return a future but when I try to label the method async it seems to create a lot of problems .

Answer : Async simply allows you to use the await keyword . See docs here https : www.dartlang.org docs tutorials futures async-await ." ] }

The next 2 responses after Andr s came just after Plastic SCM solicited comments from followers on Twitter . Maybe that s o.k . However only two followers commented .. . Answer : I made some investigation in 2010 for my company considering PlasticSCM as option . I found some places to improvement which was critical for our company . I made this being in touch with really fantastic extraordinary and responsive Plastic SCM Support Team . The problem is missing triggers for push pull operations . Also internal external API is not done yet but You can find some examples of plugins available at PlasticSCM s forum . Without hooks working on central server there is no way to use Plastic SCM in distributed scenario at our company . That is why we choose Git . Second thing is not missing but not released support for PostgreSQL . I red on forum You can ask about such ability - and PlasticSCM posses such code somewhere . PlasticSCM contain so many functions available as plugin and so rich GUI that You want to implement something more inside . But we still wait for some API to released . I can t wait this . There is also no floating enterprise licences and current per user licence model is very expensive .

Answer : I m evaluating PlasticSCM on a VMWare Machine with 4GB RAM and 4Core CPU . Since I ve ported our trunk into the server about 6GB of Data the service ran out-of-memory started swapping . I ve increased the the VM RAM to 6GB This is actually more than I d like to load the host system with since I ve also got VMs for PlasticSCM Client TeamCity Server TeamCity Agent . I was trying to find a spec with details on hardware requirement for running PlasticSCM server which incorporates scaling . So far I ve only found the minimum requirement https : www.plasticscm.com documentation administration plastic-scm-version-control-administrator-guide.shtml Chapter2 : Minimumrequirements 512MB RAM etc . and the system information of your heavy load https : www.plasticscm.com under-heavy-load index.html and scale https : www.plasticscm.com version-control-for-games.html performance-results test . As far as I can see it s all about RAM . : .. . .. . Anyway is there a detailed spec with recommendations for the hardware being used P.S . : Of course in case of switching to Plastic we d run the service on a real machine instead of VM . Comment : Hi DenDev . Look 4GB of RAM should be more than enough . I ve 18GB of repos in my laptop and the process uses like 150-200MB . Are you intensively using under heavy load tons of users . Since I guess it is not the case I can only think of eating too much memory during the port which I guess was a gitsync or similar correct If so yes during import it can use more mem typically the client not the server . Restart it should use less . Otherwise contact our support team and we ll look into it immediately . Comment : TeamCity was updating the workspace . In the meanwhile I was testing some access stuff with the ACLs . By this the TeamServer got accidentally ripped of the server access right revoked during update which might have left the server in an undefined state . At the end the server was consuming 4 5GB swapping SQL was consuming 2GB . Since restarting the service its running fine with about 200MB RAM MySQL consuming 2.7GB .

Answer : Yes you can use Plastic SCM to sync with TFS . But so far you ve to rely on the command-line . It is able to keep one branch in sync since keeping more than one gets complicated since TFS doesn t do the same sort of branch and merge tracking that Plastic does . In fact Plastic can be fully synced with Git http : www.plasticscm.com gitsync index.html pushing and pulling branches merges and concurrent changes merge tracking and everything .

One of our evaluation tasks is to test migration from our SVN repository to Plastic . We want to migrate our trunk only since the branch structure and information is somewhat broken . I was able to migrate to git with git-svn . I fast exported the git-repo with -C -M parameters . The import into PlasticSCM succeeded . However when checking out master on the imported Plastic Repo the client complains about missing files . These files don t show up in the Items list in the Client . The filenames which have issues contain octal escape sequences . It turned out that these file names have got german umlaute in them . I was testing git fast import of the exported stream . Git is able to handle theses filenames correctly .

I ve linked to a post telling about the octal coding issue . The thread is actually adressing TFS conversion issues in general . One author claims to have a script which recodes octal coded characters into an encoding which can be read by PlasticSCM fast import . However the script is not provided . Has anyone encountered this problem as well How could a solution look like I can t imagine I m the only one having this problem especially because Plastic is developed in Spain where non-english characters should encounter quite frequently .

Plastic has a transparent SCM feature : http : www.plasticscm.com features transparent-scm.aspx .. . .. . It means that you can directly modify change your code files create new ones copy move rename delete.. . and Plastic will detect all the actions you did and displays them together so you can quickly check them in and get back to coding . Tracking all these changes helps later to have a smooth merging experience so you can enjoy the benefits of branching with no restrictions . So in summary you can continue using Plastic SCM and GitHub although there is not a specific plugin for the INTEL-XDK .", "Question : I know there are some questions already regarding Plastic SCM but they are over a year old .

The next 2 responses after Andr s came just after Plastic SCM solicited comments from followers on Twitter . Maybe that s o.k . However only two followers commented .. . Answer : Yes we use Plastic SCM small team of 5 for 2 years already and it works great and even gets better every update Support is very good within an hour or at least the same day a response . Also branching-and-merging works very good in practice . Every programmer can work on it s own in his own branch using branch per task pattern . Such a big relief . When you switch to another branch all changes are automatically shelved stored on the server . When you switch back the changes are reloaded which is a really nice feature You don t have to worry to loose changes because Plastic handles everything very good . Without doubt Plastic SCM is the best Version Control System I ve ever seen used MS Sourcesafe CVS SVN StarTeam . Also heard of other s the branch support is much better than MS Team Foundation .

This youtube video looks very promising . With checkins made to Plastic appearing in TFS and vice versa via a command-line sync operation . http : www.youtube.com watch v AJKF3cjg7jA .. .

Since I have upgraded to this version of plastic every time a new file is add-in VS plastic adds that file to the Added and Private Items list but it does not auto select the items to be checked in by default As it says in plastic documentation . Does anybody know why plastic doesn t auto select the newly added items for check in as it before Is there a way to turn this feature back on .. . Answer : The Visual Studio package has two pending changes views : .. . .. . enter image description here http : i.stack.imgur.com ROkjT.png .. . .. . Pending changes under solution : It displays only those items that are under the Visual Studio Solution . In this view added and private items are automatically marked checked to be added to source control . Pending changes under workspace : It diplays all changed and private items in your whole workspace . In this view added and private items are not marked checked to be added automatically because you could have thousands if you did not configured your ignored filter . So when working inside Visual Studio I recommend you to use always the pending changes under Solution to work flawlessly . Comment : Daniel Thanks Yes in VS I can see that the new file is checked as you described above . But I am used to using the plastic client for last couple of years when there comprehensive plastic VS plug-in wasn t available . It still doesn t answer my question specific to Plastic Client although you raised a new question whether should we not use the plastic client but migrate to using VS plugin Comment : Hi @Jegan : If I understood correctly you mean that you expect to find added and private items to be automatically checked for add to source control in the Plastic GUI client In that case the answer is no . The Plastic GUI never auto selects local changes automatically to prevent the user checking-in not desired changes to the server . Comment : Yes the old version auto selects all newly added files and folders in the Added and Private Items section in Pending Changes in Workspace view but once you deselect them they will stay deselected forever . But the latest version some how disabled this feature . It is become an extra effort to select those files especially if I have lots of private items I could easily miss-out files that supposed to be checked in . Comment : @Jegan : Unfortunately the new Plastic SCM versions do not auto selects all newly added files and folders automatically to prevent the user checking-in not desired changes to the server . My recommended way of working in this case is correctly configuring the ignored filter and just clicking the added category that autoselects all its children . Hope it helps", "Question : Anyone know how to remove users in PlasticSCM when the server is configured to use Active Directory security Comment : turns out you need to use the command-line tools : br --to list the users : cm li br --to remove old users : cm du username br --to add a new user : cm au br .. . Answer : The cm au du commands are meant to activate or deactivate users . But users are not added to Plastic as such . When a user does an operation in Plastic it will be automatically added provided you have enough licences and the user has permissions to access the system you ve set the correct ACLs . Suppose you just have a 20 users license : .. . .. . You simply install the license copy the plasticd.lic file .. . Then the first user access the system it will be activated .. . Second user accesss second activation it happens automatically .. . Then suppose you already have 20 developers using Plastic and one of them leaves and a new one enters then you have to deactivate the old one and activate the new one but only then .

We are currently working with Unity3D for our project and for each time we try to merge our changes we always end up with some sort of problem. . .. . .. . We are currently using the Plastic SCM Cloud Edition . What we have tried is to work directly against the Cloud Repo but that ended up with problems merging since the cloud edition isnt able to merge content on the fly in the cloud . We then ended up creating local repositories that we then replicated the cloud repository to by simply pulling the repo then made some changes and then tried to push the local repository . However. . we then recieved a new error telling us something about the MemoryStream.. . So.. . how are we supposed to work with Plastic SCM Cloud Edition when in a smal team of 2-5 developers when working with Unity3D .. . Answer : Your last approach make sense if you don t need an on-premise server in your office . Plastic Cloud Edition is the sum of the Plastic SCM software plus a Plastic Cloud server and storage all packaged together in a single pay-as-you-go subscription . The client software and local repositories are installed on each developer s computer and then he will push pull to the cloud organization . You commented that your workflow requires branching-and-merging so the checkin update create branch and merge will be local operations and then you be just connecting to the cloud to push pull your changes . This MemoryStream message could be a hard drive is full issue but we would need more details to confirm it .

Comment : The reason I stress on this is because the Sahi scripts are way more powerful than the java driver and will get a lot done for you .

Regards .. . globalworming Comment : SOLVED Nice +1 thank you Comment : then please accept my answer :", "Question : I have so far been a partly QA Automation partly Web developer person mostly been working on QTP VBScript for Automation . Soon I will be moving on to a new project as Automation Architect . While I have the overall approach and idea for Automation Framework that I want to develop ready in my mind I need some help on deciding the Automation tool . I would love to use QTP as I would be able to use the full library for low-level functions as is from my current project . However one thing where I feel restrained with QTP is cross-browser support I feel only IE can be targeted best with QTP Firefox Chrome support is still bit limited . Also QTP doesn t allow to test on multiple browser windows at a time . I maybe wrong here the latest QTP version maybe supporting this and if so I will appreciate if you can share your experience .. . Our target apps would mostly be Web Application and target Web platforms would be IE Chrome Firefox Safari Opera . So I am also thinking to give Selenium or Sahi a try . Being a Web developer I can say I am good at JavaScript so adapting to Selenium should not be a big shift for me . However before I go ahead with getting my hands dirty with Selenium I want to hear the thoughts from the expert community here . What do you feel how good has been yours cross-browser automation experience with Selenium Sahi or your grievances w.r.to Selenium . Also how much Selenium would be helpful to when it comes to something like the flexibility we get from QTP in terms of opening the door for Automation Developers to VBscripting world we can extend the scripts using lot of supporting VBScripts system level scripting or networking related scripting or IE settings programming runtime DLL registrations or other batch files database linking ADODB using 3rd party APIs Web APIs etc XML programming using .net libraries etc . thanks in advance much appreciate sharing your valuable experience . Comment : You should gave a read through stackoverflow.com help on-topic https : stackoverflow.com help on-topic .. . Answer : This is an ongoing debate . However I from my experience would say SELENIUM . There are of course some advantages of using QTP . However with the ongoing technology in development world selenium is much better tool . Having the capability of implementing the OOP and taking it s advantage is a big factor here where qtp easily fails . Thinking abount angulars other ajax technology where selenium is improving day by day and qtp is not . And think about working in agile team side-by-side with developers who are building your app with java c . You can pretty much share there knowledge and techniques to equally support your project where using qtp your project set up will be whole lot different . And at any case if you need help from google selenium wins without any doubt .", "Question : i a automating my web there are multiple requirements but one that make me sick is that i want to take snapshot of the web page and then save it into my desire location .

Any idea how to fix that Comment : I would say the easiest way of solving this would be adding a class to your page s body tag and changing body to .body-class hopefully this should solve the issue Comment : Still no luck . I think the problem might be in using document .ready function because the iframe is loaded after this class so it doesn t take the newly added ids and classes from Thickbox . But what else should I use Comment : As it turns out there are quite a few alternatives to Thickbox some of which had these functions build into them.. . Using Colorbox for example there are functions that trigger on Open Load Complete Cleanup and Closed .

Start here : jsbin.com ezivij 1 http : jsbin.com ezivij 1 .. . Answer : Not sure if I understood everything correctly but if your table is inside an iframe you have to know that an iframe is a boundary for many things in your page . In particular layout doesn t flow through an iframe . There s the inside of the iframe and the outside . They leave in completely separated worlds and there is no way that the size of your table which lives in the document inside the iframe can influence the size of the iframe itself -- or anything that lives in the document outside the iframe . If you don t get rid of the iframe your only solution is to use javascript to copy the size from the document inside the iframe to the iframe itself . Of course this is assuming a script is allowed to do that i.e . you don t have cross-site scripting issues your iframe and the main document must come from the same origin . For clarification and to properly answer : you ask the wrong question . Setting thickbox size to auto will not help you . You must set thickbox size to the actual value dynamically .", "Question : I am trying to set content of thickbox in jquery as I want to take content from server .

This is my form code . I placed an OnSubmit function to close the Thickbox window . It works but the form does not submit . Thank you for your help .. . Answer : tb remove returns false so the form would not submit . You need to add a click handler to Add to Cart that runs tb remove and also returns true . Since you re submitting the form in an iframe you need to make sure the post fires before removing the iframe from the document . For usability it would be nice to also have a message saying your product was added to the cart when the thickbox closes . Comment : We are working in Woocommerce . Do you know what the click handler would be to trigger the add to cart function in Woocommerce Comment : @PaulRuocco this is done in javascript and is independent of the PHP framework you re running . The easiest way to do this is to create a javascript function in the parent page like function closeThickbox tb remove . Then in the iframe add a jquery event like addtocart .click function parent.closeThickbox . Although it looks like you re trying something else now.. ." ] }

There s a lot more to the Verold API not to mention what you can do by getting a handle to the Three.js renderer underneath but you can achieve a lot using events .

Is this the correct way to start an animation in a script 2 . If so could someone show me the proper way to use this i.e what are the save and fn parameters Thanks in advance.. . .. . Answer : First you need to get a reference to the Keyframe Animation component that you want to control via script . You can use getComponentsByScriptName to get the Keyframe Animation component s attached to an entity : .. . .. . If a single Keyframe Animation component is attached to the entity then this.animations 0 will refer to it . Next you can play the animation :", "Question : Not sure if this is a Verold or a 3ds Max problem . I have a scene to import into Verold with objects that animate . I want the objects to complete one animation when clicked and then start another animation on loop when clicked again . What is the pipeline for getting the animations in I can see how to do it with the character animation file on the Verold tutorial because you can import just a skelton .fbx but for objects you have to import the whole scene each time no I am not worried about how to deal with the event handler side it is getting the animations in . Do I produce the two animations in 3ds Max one after the other in the timeline and then call on them separately somehow Or do I produce two scenes with identical objects but with different animations and then somehow extract the animation alone In other words what does Verold need and how do I get there .. . Answer : Both approaches will work . First if you have a single file in 3ds Max with both animations in a single timeline you will need to split the timeline into two takes clips inside Verold . You can do this as follows : .. . .. . 1 . Click on the animation asset .. . 2 . In the Inspector select the first take .. . 3 . Click Duplicate to duplicate the take .. . 4 . Adjust the start and stop times of each take .. . .. . Then you can trigger the two takes independently with the Event Handler . Alternatively you can create two separate files each with a different animation . When you import the files into Verold you will end up with two animation assets . You can trigger these two animations independently with the Event Handler . Comment : That s great . Thanks . One more question.. . in the event handler is it possible to trigger animations sequentially through the same action i.e . click an object to start one animation then click the same object again to start the second Comment : I don t mean to have the first as a default animation already running when you open the scene I mean have a static scene first then click once for first anim then again for second", "Question : I am trying to duplicate an object every time I click it in Verold . I have attached the Object Picker to the scene and successfully triggered a function which prints to the console . I ve tried this code but I get a Type Error - can t read property of undefined . .. . Answer : The clone method is asynchronous because the same method would be used if you were creating persistent copies of your objects on the server . This function like many functions in the Verold API takes an options object as a parameter . In here you need to specify the success callback method like in the following example . Once you have the clone you then need to add it to the scene hierarchy using the addChild method . This will automatically trigger the cloned object to load . The multiple steps are useful because you may want to clone several objects and have them ready to add to the scene at a later time . And of course if you don t require the cloned object to have components or any of the other functionality of a VeroldObject you can always just get the threeData and then use Three.JS s clone method . Hope that helps .", "Question : In Verold using the Verold Studio controls how do I get the camera to rotate around the axis of the model when I pan rather than just turning on its own axis I ve searched through the controls in Studio and am unable to find the solution . I am certain it is right in front of me I just cannot see it . .. . Answer : When you click the camera then open orbit controls and the first setting in there is the object to orbit . You can set this to a model or a mesh . Depending on what you want to orbit . The other trick is that you should make sure that your camera s initial position is a valid orbit position . To do this select the model you want to orbit and click the F key . Now you can choose your camera and set it to this position using the align to position button . Hope that helps Comment : Thanks but when I double click the default camera and the Inspector opens I cannot see any setting to select the object to orbit .", "Question : First post here on stack overflow.. . I ve been playing around with the three.js based world editor called verold http : www.verold.com . It has some great features but I ve run into a problem with the scripting setup . I m trying to implement a THREE.Sprite and attach it as a component of an object . Here s what I ve tried : .. . .. . The script has an attribute called spriteimage which is a verold asset - 2D texture . When this script is added as a component of the scene the project runs but you can t see a sprite at all . I ve tried replicating this code in a regular three.js project with success . Can anybody offer a solution to this thanks . .. . Answer : There are a couple of minor issues with your code . Otherwise it works fine . First mySprite.location should be mySprite.position . Perhaps an earlier version of Three.JS used location The second issue is the reference to scene is not defined . In a script you can call this.getThreeScene to return the reference to the THREE.Scene that the object that this script is attached to is part of . Comment : Thanks Mike That fixed it . Not sure why i was calling .position I think I copied it from a previous example somewhere", "Question : Not sure if this is a Verold or a 3ds Max problem . I have a scene to import into Verold with objects that animate . I want the objects to complete one animation when clicked and then start another animation on loop when clicked again . What is the pipeline for getting the animations in I can see how to do it with the character animation file on the Verold tutorial because you can import just a skelton .fbx but for objects you have to import the whole scene each time no I am not worried about how to deal with the event handler side it is getting the animations in . Do I produce the two animations in 3ds Max one after the other in the timeline and then call on them separately somehow Or do I produce two scenes with identical objects but with different animations and then somehow extract the animation alone In other words what does Verold need and how do I get there .. . Answer : unfortunately that s not yet possible . The event handler is for basic interactivity and we re working on a next release with support for more advanced features . What I might suggest for now is to use custom actions on your scene one for each of your animations . This still wouldn t let you do sequential animations but at least that lets you trigger both of your animations . If you send an email to info@verold.com I ll add you to our list and get you in as a beta user on our timeline tool . Should be in the next few weeks . Ross Comment : Can you clarify custom actions please", "Question : There is a problem that multiple users of my model have noticed namely that when you right-click the model here http : www.verold.com projects 54ceb6560f01ac093d379058 the movements are hypersensitive . Orbit and zoom are fine and steady but pan now more often than not results on the model rapidly shooting off into the distance . I ve been playing with the camera controls to no avail and I don t want to simply remove the pan option for the client . Also is there any way to transition between cameras without a fade just a movement of the camera Also Verold not working on Internet Explorer 11.. . any news Thanks Comment : It happens very frequently when left clicking too to the point that the model is non-navigable . Comment : For instance go to camera 3 and right or left click on the drum . .. . Answer : Solved : problem was the focal point white lined sphere . Had been set off accidentally far off into the distance can be easily done without noticing and there is no undo . Just brought it back to the object .", "Question : Is there any way to make an object gradually disappear without scripting rather than go straight to invisibility using an event handler I ve tried importing an animated opacity change from 3ds Max but no luck . .. . Answer : We don t currently support animated material in FBX . For now I d suggest triggering an EventHandler to modify the material properties . Here s how : .. . .. . Add the Object Animator and Event Handler components to your object . In the Event Handler choose whatever trigger you want on pick or whatever makes sense for your usecase . Then for the action choose Asset select your material asset then choose Set Number Opacity then you can specify an opacity value and a transition time in seconds for the animation . I noticed on my machine that there is a bug during the transition have recorded the bug and should get it fixed in the next few days . But that gets you what you need .

When I remove the setProperty line then I get the color value from the editor . .. . Answer : That code should work fine and it seems to be working for me . diffuseColor is a property of materials though so make sure that you re setting this property on the MaterialAsset and not your mesh . If you want to only change the color of the material on one of your meshes you ll need to create a new material for it or clone the existing one . Hope that helps .

I ve integrated Typescript and removed ng-app . The next step is to integrate the Angular 2 libraries and start the actual migration . Before I do I would like to see if anyone has done so and has recommendations recipes on best practices to integrate the Angular 2 modules into an Angular 1 application . .. . Answer : Introduction .. . .. . I started this journey with the intent to integrate the new NG2 with the existing NG1 build-process this seemed reasonable since my goal was to build an environment for the development of hybrid NG1 NG2 applications . There are fundamental differences between how NG1 and NG2 are built : .. . .. . TypeScript : NG2 added TypeScript to the existing JavaScript and DART language options . TypeScript is a huge improvement over JavaScript and I have no intention of using DART . Module Management : NG2 adopts ES5 module management and abandons NG1 own module management . Application and vendor files are now made available as modules which are loaded by the module manager I m using SystemJS but will soon upgrade to Webpack as needed by the application . Components : NG2 component architecture strongly suggests that all artifacts css html less png etc ought to be placed in the same module folder with the module manager with a little help from the developer taking on the role of loading these files as necessary . Approach .. . .. . Well into the process to build the NG1 NG2 integrated build environment I came to the conclusion that the correct course of action would be to build the NG2 environment to be completely separate from the NG1 environment but to co-exist . Once I reached this conclusion it became obvious that this was the correct approach since once we migrate all of our NG1 software to NG2 we want to also seamlessly remove all of the NG1 build artifacts and software which would be hard to do should the two be tightly intertwined . With this in mind the following changes were made : .. . .. . config files - Created definitions calling out the NG2 files the idea was that all NG2 tasks would be made to operate on these file definitions while avoiding the existing file definitions hence leaving the option to remove not used NG1 file definitions . config application - There are two fundamental set of changes : tasks - Again I strived to create tasks doing specific NG2 work . workflow - Here is the place where the NG1 and NG2 tasks were intermingled to coexist . files .. . .. . See below for my config files.js code and some ensuing comments : .. . .. . Notes : .. . .. . files.ng2 - is an obect containing all the NG2 related file definitions .. . files.ng2.libs - is an array including the source location of the support files non-application that need to be copied to the server target folder as indicated NG2 requires vendor modules to be available for loading by the module manager . files.ng2.css : defines the CSS fils to be watched for change note that I chose not to handle less files should you be interested in doing so use the pattern used to handle ts file . files.ng2.html : defines the html fils to be watched for change . files.ng2.generated : the target folder where to place files during development the copy : dl-deploy-dev task see the config application.js file is used to copy these files to my server wildfly target folder . files.ng2.dist : the target folder where to place files when running a buid . application .. . .. . See below for my config application.js code and some ensuing comments : .. . .. . Notes : .. . .. . copy : dl-deploy-dev : used to copy these files to my server wildfly target folder . copy : ng2-libs-to-target : used to copy 3rd party library files to my server wildfly target folder . Note that I chose not to copy them to the generated folder to avoid the expense of copying a huge number of files to the target folder every time a single simple application file changes . copy : ng2-css-files-to-generated : copies changed CSS files to the generated folder . copy : ng2-html-files-to-generated : copies changed html files to the generated folder . copy : ng2-files-to-generated : used to ensure that the transpiled ts files js map and their companions html css landed on the same folder . copy : ng2-ts-files-to-generated : : copies changed html files to the generated folder . copy : systemjs-to-generated : used to copy the system.config.js file to the generated folder . copy : ng2-libs-to-dist : used to copy 3rd party library files to dist folder . copy : systemjs-to-dist : used to copy the system.config.js file to the dist folder . ts : development : used to transpile changed ts files into the generated folder . ts : dist : used to transpile changed ts files into the dist folder . watch : systemjs-config-js : watches for changes in the system.config.js and executes copy : systemjs-to-generated when changes are detected . watch : ng2-css : watches for css files changes and executes copy : ng2-css-files-to-generated when changes are detected . watch : ng2-html : watches for html files changes and executes copy : ng2-css-files-to-generated when changes are detected . watch : ng2-ts : watches for ts files changes and executes ts : development when changes are detected . watch : target : watches for app files changes and executes copy : dl-deploy-dev when changes are detected .

Answer : I ve come up with a strange unelegant workaround for this but here s the original question.. . final musings after the break : .. . .. . .. . .. . It s been a while since I ve posted on stackoverflow but this has always been the best place for me to dump my programmings woes . Here s my issue only the necessary info : .. . .. . I have an asp.net web app . In the web app I have a main.aspx page . The main.aspx file consists of two main parts : .. . .. . A custom UserControl for navigation which is included in the markup ie not dynamically loaded - no problems here . A PlaceHolder control which is used to dynamically add a UserControl in the code-behind dependent on what is clicked in the navigation control . Note that this PlaceHolder is inside an UpdatePanel.. . These UserControls load fine and the state is persisted finally - no problems here . Now - here s the problem .. . Some of those dynamically loaded UserControls placed in the PlaceHolder mentioned above contain a CKEditor control for web-based HTML editing . The UserControl itself loads nicely - state is persisted but the CKEditor control never shows .. . on creation of the UserControl I can set a watch and the CKEditor instance isn t null but it just doesn t show up in the rendered HTML . If I move it in or out of UpdatePanels or anywhere within that dynamically-loaded UserControl it s a no go . If however I take the CKEditor Control out of the UserControl and place it in any other non-dynamically-loaded control anywhere else in the web app it shows up fine . After trying some things out it looks like this isn t just a problem with CKEditor - I tried using one of my own Navigation UserControl mentioned above instead of the CKEditor control and it has the same problem of not appearing . Summary : Custom controls included in a dynamically loaded UserControl don t show up . Anybody have any suggestions or wisdom to impart Being relatively new to ASP.NET I assume I m missing something obvious . Let me know if you d like to see some specific code . .. . .. . It turns out that if the first dynamic UserControl that is loaded contains a CKEditor then it works on all subsequent dynamic UserControls that get swapped in . If the first one loaded in doesn t have it it doesn t pull up on the following ones - also the IDs need to be the same across the different controls that use it . This all seems very strange to me - the workaround works fine it just seems very unintuitive - is it something to do with the location in the page s life cycle that the CKEditor is created or some ViewState thing Either way it s working for now and I can move on . I remember now why I was more comfortable with non-web development Comment : I thought that maybe it was an issue of having a UserControl within a UserControl but that works fine . Stuck with dynamically-loaded-UserControls not displaying child UserControls . Comment : @E Ludema there can be issue with CKEditor .NET wrapper . CKEditor is essentially a java-script based editor - so all .NET control would be doing is to generate appropriate script to initialize CKEditor js object . Now script must be registered via ScriptManager when using with UpdatePanel and that can be the issue here .", "Question : I want to disable ACF on ckeditor and as many post and documentation suggest i am setting allowedcontent to true by below ways still its filtering out my html .

Replacing tag CP : CP B with any known tag like strong works fine . Am I configuring it correctly I am using latest version of ckeditor 4.4.1 . Also tried version 4.4.0 and 4.2 .. . .. . Thanks .. . Answer : CKEditor is HTML text-editor not XML editor . Don t expect it to support all XML features like namespaces . Use data-foo attributes to distinguish custom stuff from standard data .

Comment : The toll is available from ckeditor.com download http : ckeditor.com download and I would be surprised if they did not provide a full product . Maybe you could describe the issues you re having in more detail .. . Answer : If you re using ASP.NET WebForms not MVC and you re willing to use an older version of CKEditor 3.x from 2014 then you can download CKEditor for ASP.NET from the main download page http : ckeditor.com download . Scroll down until you see the CKEditor 3.6.6.2 for ASP.NET heading and click Download now . You ll get a zip file with a sample project including the DLL in debug and release versions . I just downloaded it now and it contains the DLLs . Complete setup instructions are available here http : docs.cksource.com CKEditor 3.x Developers Guide ASP.NET Integration Advanced . However if you re not using WebForms this will not be of any use to you .

Ckeditor version is for AspNet . Tested on Chrome IE 10 and IE 11 .. . Answer : Your CKEditor is presumably running on a web page with a http : address . Modern browsers don t support embedding images or anything else from file : URLs in http : pages or https : or any other protocol for security reasons . This is because there d be the danger of a malicious site embedding something from your private files like a document and then using some security hole to read and upload it elsewhere . But even if this worked it wouldn t do you much good : the image isn t uploaded into CKEditor so the image would show up on your computer only . Anyone else watching the page you re editing would see a broken image link . As far as I know there s currently no way around uploading the image separately .

I feel like sometimes I m getting weird errors with it complaining that jquery is missing when I use the asp.net control -- they don t seem to happen under the markup script based method . I haven t pinned this down yet . The overall build is the 3.6.6.2 of the asp.net control . The ckeditor build is 4.4.7 . There are custom config.js files used in some places and in some places the control is configured by markup in the asp.net control .

Comment : Please check my answer here http : stackoverflow.com questions 30029072 formatting-issues-in-asp-net-integrated-ckeditor 30075453 30075453 I tried to explain the current status of the ASP.NET control . Comment : So it seems like it is ok to keep using it until a v4 release is accomplished . I think what you outlined is what was basically done by my coworkers . I think I can rule out the ASP.NET control as a factor perhaps . Comment : CKEditor is an Open Source project so if you or your organization feel like you could benefit from an updated CKEditor for ASP.NET control and be willing to help either through collaboration or sponsorship it would be most welcome if you got in touch with us http : cksource.com contact at CKSource ." ] }

Answer : I forgot to circle back to this question after it was solved . Recently I have again migrated and updated out Teamcity installation from version 6.5 to 7.1.4 without losing any history or data so I think I d better share what I did . Basically what I did were : .. . .. . 1 . Shutdown old version 4 Teamcity installation . 2 . Dump the database used by teamcity to a .sql file . In my case we uses MySQL so I used something like : mysqldump -u User -pPassword teamcity db name teamcity.sql .. . 3 . On the new server use rsync to copy the .BuildServer folder from the old version 4 Teamcity server . 4 . On the new server create db user and database in MySQL with same names as in the old server . 5 . Import the .sql dump : mysql -u User -pPassword teamcity db name teamcity.sql .. . 6 . Unzip the new Teamcity .tar.gz distribution file to a location say home teamcity Teamcity .. . 7 . Run home teamcity Teamcity bin teamcity-server.sh start .. . 8 . Open http : your new teamcity server : 8111 and it will ask to enter maintenance mode by finding a secret token in teamcity-server.log in home teamcity Teamcity logs folder . 9 . After entering the token it asks to confirm the upgrade . This step besically upgrade the format of your .BuildServer folder . 10 . Wait sometime for me it took around 30 mins to do the upgrade . 11 . Almost done but don t forget to update build agent so that they know where the new teamcity server is .

So if they do support it it is more by luck due to GUIDs being maintained than any actual planning . Comment : TeamCity only starts partcover.exe with given commandline . It parses generated report.xml file to create reports and publish statistics . What GUIDs do you mean I checked that it is able to parse reports from 4.0.11129 . Comment : That is good news - the drop down entry in TeamCity says 2.2 and 2.3 but these are the .NET2 only versions . The latest version 4.0 - also handles .NET4 framework .

Comment : Update : When outputting the artifacts to the relative-path Output the folder is created and the files are correctly copied to it . The problem seems to be that I cannot for some reason copy the files to the inetpub wwwroot staging folder . .. . Answer : Since 6.0 TeamCity doesn t allow to publish artifacts outside of the server s artifacts directory for security reasons . I think this is your case . In server logs TeamCity logs teamcity-server.log there should be a related warning started with Attempting to publish artifact outside of build artifacts directory . If you wan t to publish files to some particular location you should probably create a separate build step which would send files by FTP or something to desired location .

I have just switched over from server-side checkouts to checkout on agents because of IO issues however.. . Initial checkout has become exceeding slow from a minute to 45 minutes . Once the repo is cloned everything is OK . Is there some configuration on the agents I can tweak to improve this Thanks for any replies in advance . What I see is the initial git files created on the agent and then there is a very long pause and then I get all my data . I can see from the process-explorer that git appears to be doing very little and there is no obvious source of throttling . .. . Answer : If it s fast on another configuration your problem is not git or github but the size of the pipe running into the machine . If you are using TeamCity in the cloud you will need to talk to JetBrains about their bandwidth . If locally talk to your sysadmins . Comment : Hi Matt not using TC in the cloud . Same pipe available on the agents as the server previously . Comment : Odd . Are they on the same network segment Possibly firewall is configured differently .

The problem seems to be that I cannot for some reason copy the files to the inetpub wwwroot staging folder . .. . Answer : I ve always used build scripts to handle this kind of process since you re using TC6 you should be able to add a second build step after your VS.NET solution builder which performs the copy move . MSBuild would probably be the preferred scripting method for doing this but you could use a simple console runner if you all you need to do is copy . Using a scripted approach you should be able to use an absolute path for the deployment directory which shouldn t be as fragile as relative paths . Comment : Thanks . Sounds like a good plan .

Answer : by using IOCP we can overcome the one-thread-per-client problem . It is commonly known that the performance decreases heavily if the software does not run on a true multiprocessor machine . Threads are system resources that are neither unlimited nor cheap . IOCP provides a way to have a few I O worker threads handle multiple clients input output fairly . The threads are suspended and don t use the CPU cycles until there is something to do .

What IOCP brings to the table is as you have correctly mentioned sharing the load between multiple threads . For most applications using OVERLAPPED I O from a single thread is simpler and more efficient . Only high volume application servers should consider IOCP . Comment : @Ben : To be honest I find that IOCP programming leads to a more understandable programming style than you get using overlapped I O . This is especially true if you ve got multiple operations going on simultaneously like you would when copying a file . Comment : @Larry : I don t know how you handle overlapped I O but I use MsgWaitForMultipleObjectsEx and completion routines .

I would like someone with experience in the use of IOCP confirm that the correct usage is : .. . .. . Call CreateIoCompletionPort function to create an IOCP . I associate my socket to my IOCP with the same function . Perform an IO operation WSARecvFrom or WSASendTo in my case .. .

Realize the reading of the buffer or the operation result . I have not described the implementations of the socket because it is not the focus but is this the correct way to work with IOCPs A second question is about the application-design in the case of sending information . I read something that said that the application that works with IOCPs would not use direct calls to the output operations such as call directly WSASendTo function but use the PostQueuedCompletionStatus function to generate an event in the thread to run this operation . According to what I ve studied I don t see any advantage in terms of performance . Assuming that both forms are applied to a thread pool there is advantage in using PostQueuedCompletionStatus to perform the output operation Comment : Microsoft documentation on I O Completion Ports https : msdn.microsoft.com en-us library aa365198 VS.85 .aspx has a number of links to succeeding topics . Interesting in that it appears you can use an I O Completion Port to queue messages between threads without any actual I O by using the GetQueuedCompletionStatus function to wait for a message in one thread and the PostQueuedCompletionStatus function in the thread sending a message .

A question Using IOCP with UDP http : stackoverflow.com questions 11361208 using-iocp-with-udp has a nice looking discussion . Comment : is this the correct way to work with IOCPs - it is one way to work with IOCPs yes . use the PostQueuedCompletionStatus function to generate an event in the thread to run an operation - not a common way to do it and offers no real benefit . There is nothing wrong with issuing a direct I O operation at the time you need to perform it . Comment : Before Windows Vista any outstanding overlapped I O operations that were initiated by a thread would be cancelled when that thread exited . To avoid this causing problems you could instead force I O operations to be executed on a thread that you controlled the lifetime of by first using a PostQueuedCompletionStatus call to transfer a request to issue an I O request to your I O thread pool . This kind of behaviour is no longer required as from Windows Vista onwards pending I O requests are no longer cancelled when the issuing thread exits . It was an esoteric design that s no longer needed .", "Question : In IOCP when starting an IO operation such as WSARecv a completion packet will be sent to the completion port when the IO operation completes .

Comment : For those still interested : Multithreaded Asynchronous I O I O Completion Ports - Dr Dubb s http : www.drdobbs.com cpp multithreaded-asynchronous-io-io-comple 201202921 .. . Answer : I O completion ports are provided by the O S as an asynchronous I O operation which means that it occurs in the background usually in hardware . The system does not waste any resources e.g . threads waiting for the I O to complete . When the I O is complete the hardware sends an interrupt to the O S which then wakes up the relevant process thread to handle the result . WRONG : IOCP does NOT require hardware support see comments below .. . .. . Typically a single thread can wait on a large number of I O completions while taking up very little resources when the I O has not returned . Other async models that are not based on I O completion ports usually employ a thread pool and have threads wait for I O to complete thereby using more system resources . The flip side is that I O completion ports usually require hardware support and so they are not generally applicable to all async scenarios . Comment : What hardware support I don t think IOCP mechanism is releated with hardware . Comment : Async I O does not use a thread pool ever . Some widely-used frameworks have put a thread pool wrapper around synchronous I O calls but that isn t async I O . Comment : IOCP does not require hardware support . Comment : @Benjamin @Paul Betts you are both right . +1 to both comments . Hardware support is not necessary for IOCP . I was wrongly under the impression that IOCP is used mostly for disk or device I O that it requires hardware interrupt support for notifying the I O completion . Comment : The phrasing here was bad but the objections are similarly misleading . The point here is that hardware can perform operations e.g . posting network buffers etc without the involvement of a userland thread . The program s thread need only wake after the hardware signals that an event of interest has occurred .", "Question : Using winsock you can configure sockets or seperate I O operations to overlap .

It seems to be a message-passing library similar to erlang actors Comment : @someguy asynchronous I O comprehends includes non-blocking sockets .", "Question : I m using I O completion ports on Windows for serial-port communication we will potentially have lots and lots of serial-port usage . I ve done the usual creating the IOCP spinning up the I O threads and associating my CreateFile handle with the IOCP CreateFile was called with FILE FLAG OVERLAPPED . That s all working fine . I ve set the COMMTIMEOUTS all to 0 except ReadIntervalTimeout which is set to MAXDWORD in order to be completely async . In my I O thread I ve noticed that GetQueuedCompletionStatus blocks indefinitely . I m using an INFINITE timeout . So I put a ReadFile call right after I associate my handle with the IOCP . Now that causes GetQueuedCompletionStatus to release immediately for some reason with 0 bytes transferred but there s no errors it returns true GetLastError reports 0 . I obviously want it to block if there s nothing for it to do . If I put another ReadFile after GetQueuedCompletionStatus then another thread in the pool will pick it up with 0 bytes transferred and no errors . In the examples I ve seen and followed I don t see anyone setting the hEvent on the OVERLAPPED structure when using IOCP . Is that necessary I don t care to ever block IOCP threads -- so I ll never be interested in CreateEvent .. . 1 . If it s not necessary what could be causing the problem GetQueuedCompletionStatus needs to block until data arrives on the serial-port . Are there any good IOCP serial-port examples out there I haven t found a complete serial-port + IOCP example out there . Most of them are for sockets . In theory it should work for serial ports files sockets etc . .. . Answer : I figured it out -- I wasn t calling SetCommMask with EV RXCHAR EV TXEMPTY and then WaitCommEvent with the OVERLAPPED struct . After I did that my IOCP threads behaved as expected . GetQueuedCompletionStatus returned when a new character appeared on the port . I could then call ReadFile . So to answer the original question : no you don t need to set hEvent for IOCP with serial ports .", "Question : Using winsock you can configure sockets or seperate I O operations to overlap .

I was just curious because there is mention of asynchronous I O support on Linux but I wasn t entirely sure whether there was support for sockets in particular which BlackAura confirmed . As a side note epoll may not be the best solution all the time see sheddingbikes.com posts 1280829388.html http : sheddingbikes.com posts 1280829388.html . .. . Answer : If you re looking for something exactly like IOCP you won t find it because it doesn t exist . Windows uses a notify on completion model hence I O Completion Ports . You start some operation asynchronously and receive a notification when that operation has completed . Linux applications and most other Unix-alikes generally use a notify on ready model . You receive a notification that the socket can be read from or written to without blocking . Then you do the I O operation which will not block . With this model you don t need asynchronous I O . The data is immediately copied into out of the socket buffer . The programming model for this is kind of tricky which is why there are abstraction libraries like libevent . It provides a simpler programming model and abstracts away the implementation differences between the supported operating systems . There is a notify on ready model in Windows as well select or WSAWaitForMultipleEvents which you may have looked at before . It can t scale to large numbers of sockets so it s not suitable for high-performance network applications . Don t let that put you off - Windows and Linux are completely different operating systems . Something that doesn t scale well on one system may work very well on the other . This approach actually works very well on Linux with performance comparable to IOCP on Windows . Comment : This is the answer I needed . Thanks : Comment : Any synchronous I O will block so long as you re writing more data than the buffer can hold . And if the data you re writing has been paged out your process will block on the page-fault . Comment : @BlackAura : Wouldn t WSAAsyncSelect support a large number of sockets on Windows with the notify-on-ready model Admittedly I ve not used it with a large number of sockets but since the socket handle is passed as an event parameter and there s no bitmask or array of sockets to query it seems like it ought to scale up magnificently . Comment : @Ben Voigt The problem with WSAAsyncSelect is that it s built around the window procedure API . Its message loop is slow compared to the other polling functions . Having to handle thousands of sockets can significantly degrade the performance of your program . By the way what do you by there s no bitmask You still have to pass flags . Comment : @Vladislav Vaintroub : WSARecv schedules the I O operation to be performed . When the operation is completed GetQueuedCompletionStatus will return . See the differences between readiness events and completion events .", "Question : I poll a lot of devices in network more than 300 by iterative ping . The program polls the devices sequentially so it s slow . I d like to enhance the speed of polling . There some ways to do this in Delphi 7 : .. . .. . 1 . Each device has a thread doing ping . Manage threads manually . 2 . Learn and use Indy 10 . Need examples . 3 . Use overlapped I O based on window messages . 4 . Use completion ports based on events . What is faster easier Please provide some examples or links for example . Comment : i have similar tool . its just lot of threads waiting for ICMP echo replies . Comment : If you put out enough pings you ll set off intrusion detection systems . .. . Answer : Personally I would go with IOCP . I m using that very successfully for the transport implementation in NexusDB . If you want to perform 300 send receive cycles using blocking sockets and threads in parallel you end up needing 300 threads . With IOCP after you ve associated the sockets with the IOCP you can perform the 300 send operations and they will return instantly before the operation is completed . As the operations are completed so called completion packages will be queued to the IOCP . You then have a pool of threads waiting on the IOCP and the OS wakes them up as the completion packets come in . In reaction to completed send operations you can then perform the receive operations . The receive operations also return instantly and once actually completed get queued to the IOCP . The real special thing about an IOCP is that it knows which threads belong to it and are currently processing completion packages . And the IOCP only wakes up new threads if the total number of active threads not in a kernel-mode wait state is lower than the concurrency number of the IOCP by default that equals the number of logical cores available on the machine . Also if there are threads waiting for completion packages on the IOCP which haven t been started yet despite completion packages being queued because the number of active threads was equal to the concurrancy number the moment one of the threads that is currently processing a completion package enters a kernel-mode wait state for any reason one of the waiting threads is started . Threads returning to the IOCP pick up completion packages in LIFO order . That is if a thread is returning to the IOCP and there are completion packages still waiting that thread directly picks up the next completion package instead of being put into a wait state and the thread waiting for the longest time waking up . Under optimal conditions you will have a number of threads equal to the number of available cores running concurrently one on each core picking up the next completion package processing it returning to the IOCP and directly picking up the next completion package all without ever entering a kernel-mode wait state or a thread context-switch having to take place . If you would have 300 threads and blocking operations instead not only would you waste at least 300 MB address space for the reserved space for the stacks but you would also have constant thread context switches as one thread enters a wait state waiting for a send or receive to complete and the next thread with a completed send or receive waking up .

We have a server that creates child processes with stdin stdout redirected to named-pipes . The pipes are opened OVERLAPPED . We ve seen that after the client issues CreateFile the I O completion port receives a packet with lpNumberOfBytes of zero -- which quite effectively indicates a connection from the client . But detecting when the child-process has closed its stdin stdout and exited does not generate a similar event . We ve come up with two approaches to detecting the named pipe disconnects .. . .. . 1 periodically poll the process HANDLE of the child-process to detect when the process has ended .. . .. . OR .. . .. . 2 create a separate thread which blocks on WaitForSingleObject on the child-process s HANDLE and when it becomes signaled the process has ended to then generate PostQueuedCompletionStatus to the I O completion port with a prearranged COMPLETION KEY . Neither of these is difficult -- but I wanted to make sure I wasn t missing something obvious . Has anyone found an alternative to being notified when a named pipe associated with IOCP has been closed .. . Answer : Ok I discovered why the IOCP was not delivering disconnect packets and it had todo with how I was testing the issue . We had developed a unittest harness and our unittest was acting as both server and client . When the child-process ended the child s write-pipe handle was still open in the unittest and therefore IOCP did not unblock any handler threads . To effectively run a pipe server requires you create a new thread and within that thread to do the work of connecting to the pipe creating the child-process and waiting for the process to end . After the child ends to then close the pipe handle which causes IOCP to then deliver a dequeue packet with lpNumberOfBytes set to zero . Here is a sample of how we did this from a thread created with beginthread .", "Question : I need to add timers support in an application based on I O Completion Ports IOCP .

But remember that if there are multiple worker threads only one of the thread will be notified .", "Question : WSASend will return immediately whether the data will be sent or not . But how to make sure that data will be sent for example I have a button in my UI that will send Hello World when pressed . Now I want to make sure that when the user click on this button the Hello World will be sent at some point but WSASend could return WSAEWOULDBLOCK indicating that data will not be sent so should I enclose WSASend in a loop that does not exit until WSASend returns 0 success . Note : I am using IOCP . Comment : Since you are using IOCP you should have already been aware that like any other IOCP operation WSASend will take the entire data and notify you with an IOCP completion status when the send is fully finished even if the send completes immediately unless you use SetFileCompletionNotificationModes FILE SKIP COMPLETION PORT ON SUCCESS to disable it . WSAEWOULDBLOCK does not apply to IOCP ERROR IO PENDING WSA IO PENDING is used instead . Comment : Right asynchronous operations whether IOCP overlapped event or completion callback model use WSA IO PENDING rather than WSAEWOULDBLOCK . Comment : WSAEWOULDBLOCK applies only to nonblocking sockets . Comment : But MSDN says about WSAEWOULDBLOCK : Overlapped sockets : There are too many outstanding overlapped I O requests . Comment : That should not apply to you since hopefully you will only have one outstanding IO at a time . This is the standard way to go about things . .. . Answer : Overlapped Socket I O .. . .. . If an overlapped operation completes immediately WSASend returns a value of zero and the lpNumberOfBytesSent parameter is updated with the number of bytes sent . If the overlapped operation is successfully initiated and will complete later WSASend returns SOCKET ERROR and indicates error-code WSA IO PENDING . .. . .. . .. . The error-code WSA IO PENDING indicates that the overlapped operation has been successfully initiated and that completion will be indicated at a later time . Any other error-code indicates that the overlapped operation was not successfully initiated and no completion indication will occur . .. . So as demonstrated in docs https : msdn.microsoft.com en-us library windows desktop ms742203 v vs.85 .aspx you don t need to enclose in a loop just check for a SOCKET ERROR and if the last error is not equal to WSA IO PENDING everything is fine : Comment : Yes - I just edit my answer from WSAEWOULDBLOCK to WSA IO PENDING .

Indy 10 provides experimental support for the Fiber and I O Completion Ports API in the Windows platforms . This support is designed to aid in creating more scalable servers where thousands of simultaneous client connections are required . For small- and medium-sized projects the traditional thread-based servers are still available . .. . Fiber and IOCP APIs are supported only for the Windows 2000 2003 and XP operating systems using Delphi version 7 . Windows 95 98 and ME are not supported . Delphi compilers prior to version 7 are also unsupported due to critical changes in the VCL since those releases . This is not installed by default and I haven t used it myself so I am not sure how much usable it is . I guess you need to download the latest SVN revision from their repository to use this experimental feature .

This means that calls to perform I O are returned immediately while the actual operations are completed asynchronously by separate worker threads . Winsock also provides completion ports .

I am using the following simple line to do this : .. . .. . Where OnPushData is a callback contract operation that is implemented on the client-side . Since this line is representing a Response Output operation using some network-interface and WCF is also relying on ThreadPool threads that can be used as a worker threads or I O CompletionPortThread it will be a good idea to utilize I O CompletionPortThreads by writing to completion port using TAP or APM Patterns As the article I referred to is suggesting instead of using a normal worker thread which will increase the performance considerably . Comment : I m not sure you re using the right tool for the job . IIUC you re programming read : rolling your own a pub sub server . Perhaps existing implementations would give you a good solution in less time . Take a look at SignalR signalr.net http : signalr.net Redis redis.io topics pubsub http : redis.io topics pubsub etc .

You are using WCF in a way that against its original design . Every WCF call should be small and quick with a reasonable timeout . Like the other comment suggests for unpredictable timeout case or long execution tasks SignalR is a way better solution to try . Comment : The processing time itself is not that much .

I can not switch to SignalR right now cause WCF is a standard for our company and the whole application is already built on top of WCF . I am using parallel.for each for only to call a client callback method which is pretty much defined as a Duplex contract for WCF . Comment : Lex Li Thanks for your helpful link it explains a lot . .. . Answer : Short Answer : .. . The trick to be able to use Async I O with Duplex WCF Contract is the following simple code : .. . .. . Simply you need to change the return-type of your callback contract method to be Task . but this is not enough you need to implement an async method like this : .. . .. . That is all . This actually boosts the performance of my application . and Now I am able to see I O completion Ports threads utilized calling ThreadPool.GetAvailableThreads workers IO .. . .. . Some Explinations : .. . As I understand to be able to use Async I O mechanism you will need to do the following : .. . .. . 1- Determining your I O operation . 2- A method that will encapsulate your async I O logic . 3- A callback mechanism that will be called when async I O is finished and its purpose mainly is to get the result-of the Async I O . 4- An object that will holds your Async I O result . .NET framework provides 3 design-patterns to do so : .. . .. . 1- IAsyncResult Asynchrnous Pattern : where Beginxxx and Endxxx will encapsulate your async logic along with a Callback Delegate that represents the callback method and of course an IAsyncResult object used to hold your async I O result . 2- Task Based Asynchronous Pattern : Using one class only which is Task along with async-await keywords that facilitate the using of TAP pattern . 3- Event Based Asynchronous Pattern . .. . .. . You can read more about how you can use these patterns with WCF Services at How to Implement an Asynchronous Service Operation https : msdn.microsoft.com en-us library ms731177 v vs.110 .aspx .. . .. . However The previous link is great for implementing async request response service though there is no explanation on how to do so with callback contract . Unfortunately in my case I have to implement a subscriber publisher patttern using WCF framework where data publishing is initiated by the service side periodically each 1 second . More Details : .. . I will try to make this as short as possible : .. . WCF is relying on ThreadPool provided by .NET Framework . ThreadPool has 2 kind of threads : .. . 1- Worker Threads : for Compute-Bound operations . 2- I O Completion Port Threads : Used to get the result-of an I O operation . You must differentiate between IOCP Thread and IOCP Object initiated by CLR . IOCP Thread role is to deliver the result-of I O operation while IOCP Object is the one initiated by CLR to recieve all I O requests . In other words they collaborate to achieve I O operation . First thing you need to know is that any I O request you made will result in a system call that will initiate an object Called IRP I O request Packet whether you are using synchronous or asynchronous paradigm . I O Completion Port IOCP is nothing but a queue-like object initiated by the CLR . This object is responsible for receiving all I O Completed requests IRPs . At this point there are 2 possibilities here : .. . 1- Your I O operation is called by a synchronous method : In this case the caller thread will be blocked until your I O operation is done . 2- Your I O operation is called by an async method : In this case the caller thread will continue the execution and it will not be blocked for the I O operation until completion . Supposing that you are using async method When your async I O operation is completed this means the IRP object is processed and now it will be queued to IOCP object . ThreadPool IOCP threads will come to play the role of pulling the relative IRP from IOCP which will be wrapped in IAsyncResult for APM or Task object for TAP and passing this object to your application Level through a Callback Mechanism .

But this is a pretty direct usage of the API and this question is directed at those who have a knowledge of IOCP not Python . As I understand the documentation for CreateIoCompletionPort you specify your user defined completion key when you call this function with a file handle in my case a socket you are associating with the created IOCP . When you get around to calling GetQueuedCompletionStatus you get a completion key-value along with a pointer to an overlapped object . The completion key should identify what overlapped object and request has completed . However let s say I pass in 100 as the completion key in my CreateIoCompletionPort call with an overlapped object . When the same overlapped object has its IO completed and it arrives back through GetQueuedCompletionStatus the completion key that accompanies it is much larger and bares no resemblance to the original value of 100 . Am I misunderstanding how the completion key works or must I be doing it wrong in the source code I linked above .. . Answer : You should think about the completion key as per connection data and the extended overlapped structure as per i o operation . Some people use an extended overlapped structure for BOTH and store all the information that they need in the extended overlapped structure . I have always stored a reference counted object that wraps my socket in the completion key and a reference counted data buffer as an extended overlapped structure . If you re interested you can see some example IOCP code in C++ here http : www.serverframework.com products---the-free-framework.html . The completion key is effectively just an opaque handle to data that the I O completion system will give back to you when a completion occurs on the socket .", "Question : I m currently working on a server application that s written in the proactor style using select + a dynamically sized thread pool there s a simple mechanism based on keeping track of idle worker threads . I need to modify it to use IOCP instead of select on windows and I m wondering what the best way to utilize threads is . For background information the server has stateful long-lived connections and any request may require significant processing and block . In fact most requests call into customer-written code which may block at will . I ve read that the OS can tell when an IOCP thread blocks and unblock another one but it doesn t look like there s any support for creating additional threads under heavy load or if many of the threads are blocked . I ve read one site which suggested that you have a small fixed-size thread pool which uses IOCP to deal with I O only which sends requests which can block to another dynamically-sized thread pool . This seems non-optimal due to the additional thread-synchronization required although you can use IOCP as well for the tasks for the second thread pool and the larger number of threads needed extra context switching . Is that the best way Comment : I m not sure I understand what the problem is . You can easily keep track of how many threads are available i.e . waiting for a completion packet and start additional threads if the number drops too low . .. . Answer : It sounds like what you ve read is one of my articles on IOCP most probably this one http : www.codeproject.com Articles 2337 A-reusable-high-performance-socket-server-class . That s likely a bit out of date now as the whole problem that it sort to avoid that of I O being cancelled if the thread that issued it exits before the I O completes is no longer a problem with any of Microsoft s currently supported OS s it s only an issue on XP and before . You re correct in noticing that my design from 2000 2002 was sub optimal from a context switching point of view but it worked pretty well at the time given the constraints of the underlying API . On a modern OS there s no real advantage in having separate thread pools for I O and blocking work . A more modern solution would probably involve dynamically expanding and reducing the number of I O threads servicing the IOCP as required . You d need to track the number of IOCP threads that are active i.e . not waiting on GetQueuedCompletionStatus and spawn more when there are too few . Likewise just as a thread is about to go back and wait on GQCS you could check to see if you have too many and if so let it die instead . I should probably update those articles .", "Question : I have the following simplified IO Completion Port server C++ code : .. . .. . 1 The first issue I have is with the initial read . On client connection accept I issue a read . As the client hasn t sent any data yet WSAGetLastError is WSA IO PENDING and the read method returns . When the client then sends data the thread remains stuck in the GetQueuedCompletionStatus call as I assume I need another WSARecv call . Am I supposed to keep looping the read method until data arrives That doesn t seem logical I thought by issuing the initial read GetQueuedCompletionStatus would complete when data arrived . 2 I need to read and write data bi-directional without acknowledgements . Therefore I ve also created a client with the IOCP thread . Is it actually possible to do this with completion ports or does a read have to be followed by a write Sorry for what feels like basic questions but after trawling the internet and building IOCP examples I m still unable to answer the questions . Many thanks in advance . .. . Answer : On client connection accept I issue a read . As the client hasn t sent any data yet WSAGetLastError is WSA IO PENDING and the read method returns . That is normal behavior . When the client then sends data the thread remains stuck in the GetQueuedCompletionStatus call as I assume I need another WSARecv call . No you do not need another call . And if it is getting stuck then you are not associating the read with the I O Completion Port correctly . Am I supposed to keep looping the read method until data arrives No . You need to call WSARecv one time for the initial read . The WSA IO PENDING error means the read is waiting for data and will signal the I O Completion Port when data actually arrives . DO NOT call WSARecv or any other read function until that signal actually arrives . Then you can call WSARecv again to wait for more data . Repeat until the socket is disconnected . I thought by issuing the initial read GetQueuedCompletionStatus would complete when data arrived . That is exactly what is supposed to happen . 2 I need to read and write data bi-directional without acknowledgements . Therefore I ve also created a client with the IOCP thread . Is it actually possible to do this with completion ports .. . .. . Yes . Reading and writing are separate operations they are not dependent on each other . does a read have to be followed by a write Not if your protocol does not require it no . Now with that said there are some issues with your code . On a minor note WSAAccept is synchronous you should consider using AcceptEx instead so it can use the same I O Completion Port for reporting new connections . But more importantly when a pending I O operation fails GetQueuedCompletionStatus returns FALSE the returned LPOVERLAPPED pointer will be non-NULL and GetLastError will report why the I O operation failed . However if GetQueuedCompletionStatus itself fails the returned LPOVERLAPPED pointer will be NULL and GetLastError will report why GetQueuedCompletionStatus failed . This difference is clearly explained in the documentation https : msdn.microsoft.com en-us library windows desktop aa364986.aspx but your while-loop is not accounting for it . Use a do..while loop instead and act according to the LPOVERLAPPED pointer : .. . .. . On a side note instead of using an event object to signal when completionPortThreadProc should exit consider using PostQueuedCompletionionStatus https : msdn.microsoft.com en-us library windows desktop aa365458.aspx instead to post a termination completionKey to the I O Completion Port then your loop can look for that value : Comment : Hi Remy Many thanks for your long explanation it s very much appreciated I was going insane here . I will work through your comments and report back I took a fair amount of the code from other examples which I assumed worked . Comment : Hi Remy ok the new loop was key and specifically checking GetLastError in if perIoData . I O had failed with WSA OPERATION ABORTED hence why it never completed . I had an accept thread that issued the read and then ended . I would have thought it would have still worked but obviously my design is wrong . Many thanks for your help I will use your thoughts in my new design . Hopefully your comments will also help others as a lot of examples seemed to use code like mine . Comment : When a thread terminates any I O operations it has started that are still pending are automatically aborted . You should be calling WSAAccept in a loop within a thread that lives for at least the lifetime of the listening socket or move the client acceptance to the IO Completion Port and issue the initial accept from such a thread so I Os don t get aborted. . Comment : Understood and thanks Comment : Remy the thread termination and outstanding I O issue ceased to be an issue from Windows Vista onwards.. .

Answer : Your problem description is a bit vague as to what your actual problem is so I may be guessing a bit . BTW 68HC11 is big-endian . The 68HC11 has a 16-bit accumulator so as soon as your result overflows this you need to do math operations in pieces . I suppose you mean that by changing N from 10 to 40 your fibonacci number becomes too big to be stored in a 16-bit variable . The use or not of pointers is irrelevant to your problem as you can solve it both with or without them . For example you can use a pointer to tell your routine where to store the result . Depending on your maximum expected result you need to adjust your routine . I will assume you won t need to go over 32-bit result N 47 2971215073 .

I see they describe the number of cycles per instruction in the isa documents so that would imply a no it isnt . Doest mean there isnt some open core somewhere that does.. . Comment : Can you give more information about that Comment : what do you mean a pipelined processor cannot document the number of clocks per instruction because it depends it is not possible to exactly document . So if you have the clocks documented 1 you can usually see from the instruction and options exactly why it takes that many cycles and 2 it isnt pipelined in the sense that we use that word with modern processors . .. . Answer : If the instruction-set documentation lists fixed numbers of clocks per instruction or instruction variation then it is a pretty safe bet that no it it is not pipelined like we would think of a modern processor . Remember that the word performance is relative trading power and real estate for operations per second . Nothing comes for free . In the microcontroller world you might be more interested in ops per watt and price per unit than ops per second . Even with what we might call inefficient instruction sets or implementations we still turn down the clock rates on the parts to save power that is how much performance we have to spare.. .

After separated the four bits how do i make the assembly to convert it to hex And to when I get the hex characters I need to compare them to each ascii possible character I really dont know where to start . .. . Answer : You can use bitwise shift and masking to separate the 4 bits for each hex digit .

Here is what I have programmed thus far Comment : Unless you re using P E assembler which has default hex radix LDY 8000 should be LDY 8000 .

Answer : Increment the counter when the bit is 1 loop until it goes to 0 again and then start back at the beginning waiting for it to change to 1 . Comment : so would the program go like this updated in question Comment : Assuming BRSET means branch when set I would move the BRSET loop after INCX so the logic is loop while clear increment because it is no longer clear loop while set .

Comment : Sorry but I think you need to check your assembly course again or read a book tutorial . This is not the place to learn assembly . Comment : Right but your question is too broad . Read the FAQ . Comment : You need to do everything yourself in assembly . The simplest representation of an array is a consecutive sequence of same-size values starting at a certain memory location .

Answer : If you have memory at address 800 simply write and read your data there using the instructions of 68HC11 . You don t need to declare the array in some special way .

Unfortunately the 6811 code generator doesn t seem to be a standard part of gcc --- I don t spot the documentation in the manual . So I can t point you at platform-specific bit of the docs . But the generic bit you need to read is here : http : gcc.gnu.org onlinedocs gcc-4.8.1 gcc Extended-Asm.html Extended-Asm .. . .. . The syntax is freaky but the summary is : .. . .. . ...where inputs and outputs are lists of constraints which tell gcc what value to put where . The classic example is : .. . .. . f indicates that the named value needs to go into a floating-point register indicates it s an output then the names of the registers are substituted into the instruction . So you ll probably want something like this : .. . .. . ...where i is a variable containing the value you want to modify . Z you ll need to look up in the 6811 gcc docs --- it s a constraint which represents a register which is valid for the asm instruction which is being generated . The 0 indicates that the input shares a register with output 0 and is used for read-write values . Because you ve told gcc what register you want i to be it can integrate this knowledge into its register allocator and find the least-cost way to get i where you need it with the least amount of code . Sometimes no additional code . gcc inline-assembly is deeply contorted and weird but pretty powerful . It s worth spending some time to thoroughly understand the constraint system to get the best use out of it . Incidentally I don t know 6811 code but have you forgotten to put the result-of the op somewhere I d expect to see an stx to match the ldx . Update : Oh I see what bset is doing now --- it s writing the result back to a memory location right That s still doable but it s a bit more painful . You need to tell gcc that you re modifying that memory location so that it knows not to rely on any cached value . You ll need to have an output parameter with constraint m which represents that location . Check the docs . Comment : Not surprised you didn t find it m68hc11 support was deprecated in 4.6 and removed in 4.7 . I don t actually need the value of X after I m done bset Bit SET and bclr Bit CLeaR only have zero-page and indexed addressing modes hence the save load and restore of the index register . I ll check the docs thanks . Comment : After a bit of experimentation I m now convinced that this is the correct solution . I m having a bit of trouble with indexed addressing but I ll post that as a separate question .", "Question : The title is basically it . I have lights that i need to switch on and off . There is a button that dictates which light it should be . So when the button is pressed or not pressed i modify a variable that contains the PORT address of that light . To turn a light on i have to store 00 at that address . For instance : .. . .. . So what i want to do is have a variable PoSelect 0000 . And use it instead . This however just stores the contents of accumulator a into the variable PoSelect . What i want to do is store the contents of accumulator a into the address that is stored at the variable PoSelect . Essentially using the variable PoSelect like a pointer . How do i do that .. . Answer : Assuming this is HC11 you might want to use indexed addressing http : www.clear.rice.edu elec201 Book 6811 asm.html SECTION001832000000000000000 something like :", "Question : On my 8-bit Freescale HCS08 micro whenever I call a library function that returns values to pointers I pass it and I don t really want them I threw in a NULL e.g . The type of the last argument is uint16 t and returns the number of characters actually sent a value I don t care about . However I was having problems with port A on my micro being hosed every time that function was called and debugging pointed me to that argument screwing things up . Port A s configuration registers live at addresses 0x0000 and 0x0001 which is where NULL aka void 0 points . I thought NULL was somehow magic where it wouldn t actually do anything but it doesn t seem so . My workaround feels really hack : .. . .. . Is there a better solution I tried defining MNUL to an unused segment of memory on my processor but that causes an immediate reset . Comment : I like your solution but I wouldn t refer to it as null . .. . Answer : The function is trying to write a value into wherever the last argument points . You re passing in NULL 0x0000 so the result is being written to the memory location 0x0000 or your port A . Usually in general programming the function would check the argument and not try to write to the location if it was NULL but it appears this function doesn t follow that convention . You need to allocate a variable for the function to write its result to even if you aren t going to use it . Comment : In deeply embedded systems an 8-bit micro certainly qualifies you won t have very many sanity checks on arguments if any at all . I would not expect any protection from the NULL pointer especially not when it is a perfectly legal address of a hardware device in the platform . Comment : Even in non-embedded systems if the function isn t documented to handle NULL pointers then the assumption is that you cannot pass a NULL pointer to it .

Answer : The build-pysnmp-mib script is obsolete since pysnmp 4.3 . Please use mibdump.py tool version 0.0.7 and up from the pysmi http : pysmi.sourceforge.net package to produce pysnmp MIB modules . You could use produced modules with any pysnmp version . The following fetched CISCO-LWAPP-MFP-MIB from http : mibs.snmplabs.com asn1 and compiled it into pysnmp form along with all other MIBs it depends on : .. . .. . You could pass mibdump.py URL s for authentic Cisco MIBs repository so it would fetch possibly more recent MIBs directly from there . Alternatively if you upgrade pysnmp to version 4.3 you would not need explicit MIB conversion -- it would be all done behind the scenes by pysnmp . Including ASN.1 MIB files search and download from the Internet . Former libsmi-based conversion process is very fragile and buggy . Comment : I tried using mibdump.py but getting errors with that as well . I m thinking i m going to abandon python and use something else Comment : It is not very probable that pysmi is seriously buggy . But sometimes MIBs are . If you are willing to get you issue resolved I d need more details on the failure . Comment : Added some more detail above . MIBDump.py is displaying errors on every MIB I try Comment : Alright that was a bug in pysmi . It is fixed in release 0.0.7 and I am able to convert those CISCO MIBs with mibdump.py .

Will I be able to query the already existing NET-SNMP MIB on a device Or do I have to create the MIB on the Agent side with PySNMP .. . Answer : To monitor a host via SNMP you need SNMP Agent running locally on that host talking to host s subsystems OS applications collecting various metrics . Then SNMP Agent could communicate those metrics to SNMP Manager thus performing monitoring . Here http : pysnmp.sourceforge.net docs snmp-design.html you could find some general notes on SNMP design . There are many approaches to making SNMP Agent gathering system information from a host it is running on . You could do that from a single callback function invoked by SNMP Agent no MIB is involved or you could embed your system probes right into pysnmp MIB module scattering probes over managed objects defined in MIB so that the probes could be run once Manager hits that part of MIB via a query to SNMP Agent managing that MIB . There is pysmi http : pysmi.sourceforge.net tool that can compile text MIB into pysnmp Python module .

You do not need to specify path to your MIB module if it resides in .pysnmp mibs -- this path is hardwired into pysnmp .

Answer : With PySNMP you have MIB text file converted into Python code which serves both Manager and Agent sides of your SNMP app . The conversion is performed with the smidump libsmi2pysnmp tools like this : .. . .. . See PySNMP distribution for a little automation script tools build-pysnmp-mib . Once you have a Pythonized MIB Manager side can use it for visualization purposes represent OIDs in words prettify values . Agent application can extend Pythonized MIB by adding leaf objects that have access to the values on the host system you wish to manage .

Thanks a lot", "Question : I have been searching a lot for this but not found anything that fits my needs yet . I want an elegant way to work with SNMP tables in Python . I have looked at pysnmp and net-snmp python bindings . At the moment I am working with net-snmp bindings as it seems more easy to query data with and it is already easily available on CentOS6 where the software will have to run Python 2.6 but I would not mind installing pysnmp either . What I want is any kind of object which I can hand over my important data of my table structure such as table base OID index OID and names and oids of the columns I am interested in . I would like to get a data structure back that makes it very easy to iterate over the rows fetch lists of entries of any of the columns etc all without having to bother with OIDs and stuff anymore really abstracting all this away . The purpose of this is that I want to use as little code as possible to query all data from a SNMP table and work with it I would like to have all boiler plate code in a module so I can fetch and work with data of a SNMP table in just a few lines-of-code . What would you suggest me to do Writing my own abstraction based on pysnmp or netsnmp Is there anything in pysnmp s High Level API that I might have missed Maybe a python-module that abstracts one of the above mentioned to make it more easy to access the data Would be very glad to hear your advices . Comment : Standards such as RFC3416 define the approaches to perform table traversal . You should check the library you use has something like those . If not they are still quite easy to implement . .. . Answer : Speaking of pysnmp there are two components that may be of interest to you : .. . .. . ObjectType ObjectIdentity http : pysnmp.sourceforge.net docs pysnmp-hlapi-tutorial.html working-with-snmp-tables classes representing MIB object and handling OID - symbol - index and value types matters .. . High-level API http : pysnmp.sourceforge.net docs pysnmp-hlapi-tutorial.html snmp-command-operations operating over ObjectType instances .. . .. . On top of these two components you could read http : pysnmp.sourceforge.net examples hlapi asyncore sync manager cmdgen table-operations.html fetch-table-row-by-composite-index modify http : pysnmp.sourceforge.net examples hlapi asyncore sync manager cmdgen modifying-variables.html coerce-value-to-set-to-mib-spec MIB objects referring to them by their MIB names and symbolic indices e.g . knowing nothing about the OIDs being involved . The ObjectType class would transform values between their human-friendly representation and base SNMP types .

Generated and amended TRS-MIB.py : .. . .. . Update : .. . .. . I now have one error left : .. . .. . The debug is : .. . Answer : As for implementing a Managed Object Instance you have two choices : .. . .. . 1 . Load and subclass the MibScalarInstance class then override its readGet method to make it returning your live value . Then instantiate your new class make sure to pass it appropriate OID that identifies it and pass it to exportSymbols so its OID will get registered at pysnmp Agent . 2 . Load the Integer32 class subclass it and override its clone method to make it returning your live value . Then load the MibScalarInstance class instantiate it passing appropriate OID and the instance of your Integer32 subclass then pass MibScalarInstance object to exportSymbols so its OID will get registered at pysnmp Agent . It may make sense to keep all your code in your own MIB module . Take a look at pysnmp smi mibs instances .py to get an idea . From within your Agent app invoke mibBuilder.loadModules TRC-MIB to load your MIB module into Agent . In your code you seem to somehow combine the above two approaches : MyDeliveryTime.readGet will not work however MyDeliveryTime.clone or deliveryTimeInstance.readGet will .

Thank you . .. . Answer : Second capture shows missing GetResponse packets . Assuming timeouts do occur due to slow agent consider making pysnmp waiting longer and possibly retrying less : .. . .. . If it is rather a connectivity issue try retrying more aggressively : .. . .. . Also note that in pysnmp capture but not in code you request 25 variables in response where snmpbulkwalk wants just 10 . Too many variables may stress your agent . Comment : That not it snmpbulkwalk switching from GetBulk to GetResponse after first timeout . pysnmp continue with GetBulk until timeout . Comment : GET and GETBULK are different command SNMP does not mandate them to be used together . If you want to emulate snmpbulkwalk you could make your Python script calling getCmd along with bulkCmd . To address your original concern : pysnmp does not mix timeout with no-such-oid error condition .

As a semester project I started to implement a MIME parser to show how you can interleave multiple parsers with a MIME parser when you have a multipart message . It s really an early implementation and does not follow the RFCs because I only focused. . Comment : on the interleaved part . Nevertheless you can maybe tweak complete the current implementation I started very incomplete github.com alexcrt interleaved-parsers blob master src main https : github.com alexcrt interleaved-parsers blob master src main scala mime MIMEParser.scala . I used the parser-combinators API . If you have a clear well defined grammar for your input then it shouldn t be very hard to complete this code to parse the email messages . However you may want to look at other libraires for MIME parsing . If you re not limited to Scala you may try Flanker github.com mailgun flanker https : github.com mailgun flanker which can parse MIME messages .

Created a jar called apache-mime4j-0.8.0-fix.jar and pushed into the lib folder .. . 6 . I use run.sh so replaced the mime4j core jar name with the above one . I am sure there is some mismatch between spooler and mime4j . I think the calling code should use the Builder instead of directly trying to instantiate the MimeConfig .

However I haven t managed to find out how to connect to a mail-server to then use mime4j to parse messages . Javamail provides session and connections to a mail-server via IMAP or POP3 from which you then read Messages . As far as I can tell mime4j does not offer anything equivalent . So how can I connect to mail servers to use mime4j Can I use Javamail in conjunction with mime4j I have tried using the javamail Message.getInputStream method to get an input stream that I pass to mime4j s DefaultMessageBuilder.parseMessage . However the result is not what I expect : for a multipart message containing a plain text part and an html part only one TextBody is created . I suspect this is because the DefaultMessageBuilder.parseMessage is expecting a stream for the whole message not just the body but that javamail Message.getInputStream only provides the body . In fact I m only interested in the body since this is what was causing problems with Javamail but parsing the whole message if I could get it as an input stream form Javamail would do just as well . Any help greatly appreciated .. . Answer : If you re using POP3 all the message parsing happens on the client-side in JavaMail . Have you looked at the many properties you can set in JavaMail to configure how parsing errors are handled If you re using IMAP most of the parsing is done by the server . What sort of parsing errors are you still having with JavaMail Are they problems parsing the content of the email messages or problems parsing the IMAP protocol messages With more details of the problems you re running into I might be able to help you configure JavaMail to work for you . If you really want to use another MIME message parser you ll need to use the Message.writeTo method to get the entire MIME content of a message which you can pass to some other library to parse . Comment : I ve been using IMAP but experiencing hanging when using methods on the Body using Javamail rather than errors . I tried various suggested methods to force parsing on the client-side like making a copy of the Message but none worked . Perhaps just using POP3 would work better . Just tried the Message.writeTo and it works . I tried it before but must have misinterpreted the results . Thanks Comment : Hangs usually mean your server is broken . Again I m glad to help you make JavaMail work but I need a lot more details of the problems you re having . Feel free to send me the details at javamail ww@oracle.com if you don t want to deal with it here . Comment : Thanks for your offer of help Bill .

Answer : The simplest approach would be to use the Mime4J Message.writeTo method to write the message to a ByteArrayOutputStream then wrap the byte array with a ByteArrayInputStream and use that to construct a JavaMail MimeMessage object .

I am attempting to read a given message event as defined by the START MESSAGE and END MESSAGE headers as an entire event as I will be moving the process to a distributed filesystem eventually and need to plan for file-split boundary traversing . For the event-based parsing in mime4j a ContentHandler interface is required and methods are called from it by the parser which requires the handler be set to it . I have experimented with a sample Handler from another SO answer that extends the mime4j packaged SimpleContentHandler but that one really only parses headers . I am trying to build my custom ContentHandler class to gather the complete message as one event . I would then need to have the event in a temporary object so I could parse headers their fields and the contents of the fields out of it .

Answer : You may need to check whatever process is trying to run the script has permissions to the file referenced . Sometimes tasks are scheduled to run as accounts that dont have the permissions to read the script file etc . It should be fine if you are just double-clicking the wsf s interactively on the machine and your account has permissions to open the file in notepad . As Pekka noted if the script was scheduled as a task it will run in a non-interactive process where S : may not be mapped .

What are the use cases for both of them and when should i prefer one over the other Here is the other example .. . Answer : Modules would let you expose several functions and classes . InternalFunction only exposes one function at a time . InternalFunction is something of a curiosity that we added at some point to answer a can we do that type of question . It is one of these things that stay in Rcpp because they once were but that does not get too much attention from us . It is mostly used in RInside to allow R code to call c++ functions . This is a curious pattern given that with RInside the focus is a C++ application embedding R . .. . .. . Modules however do get a lot of attention . My advice would be to use them . Comment : true I agree with your comments there are some use cases of InternalFunction for example a function in C++ passed to an R optimization library but its definitely not a show stopper if you avoid InternalFunction .

Because of my limited knowledge in programming I really do not know what to do now . Hope this time my question is better aksed Comment : That is pretty excessive downvoting . It is a fair question and reasonably clearly posted . .. . Answer : Your question did not show how you launched the compilation . RInside depends on both R and Rcpp and therefore uses a moderately complex Makefile . But if you just that things should work . On my Ubuntu 14.04 system and using the code in the git-repo for RInside which gets installed with the package you get from CRAN : .. . .. . This is pretty verbose since I changed the Debian Ubuntu package of R to reflect many of the default hardening flags plus we need headers and libraries for several things . But the main thing is : just say make in the examples directory and everything should build . Comment : Hi Dirk thanks so much for your answer . I just stayed in the RInside examples standard directory and say make in the terminal . I think that I do all the things following the standard steps . But it seems the compilation still does not work . In addition I get the R by calling apt-get install .

Then I copied code from sample1 into another file of mine and set it up to compile using Makefile . Also copied sample copies into the same directory . The samples in the directory compile and run fine . But using R in my already existing code is giving issues . When compiling it gives an error saying expected unqualified-id before return . This happens in the line where I declare RInside R argc argv . Another weird thing i noticed is if i include at the bottom of included files I get a bunch of errors in Rcpp etc . but if i include it at the top all those errors disappear . Also is the default compile option of -O3 required for the package I have been using -Ofast for most of my codes . Browsing through the questions here I think I need to make changes to CXXFLAGS in Makevars but i can t find out where . Any help appreciated . I have boiled down the errors to another file included in my setup which is k.h . This is a file which is used to interface c++ with kdb+ database . If I include the file before I get errors in Rcpp classes . When included after RInside I get the earlier error of unqualified id before return .

Comment : figured out where to change the -O3 to -Ofast Comment : There is nothing reproducible or tangible here . Either edit the question to make it useful or delete it . Comment : have made it more tangible and reproducible but it is still too specific a question but might help others too who are trying to do the same . simply adding the above file into any of the samples will cause compilation errors .

Answer : Yes and as I wrote earlier to the rcpp-devel list http : news.gmane.org gmane.comp.lang.r.rcpp which you should follow if you care about Rcpp and RInside I just added an example to RInside http : dirk.eddelbuettel.com code rinside.html which embeds it inside Qt http : http : www.qtsoftware.com .

Answer : I think you get that issue when your .libPaths differ--in other words run the .libPaths function to see the paths stored by R for its use . Then check where RInside is installed and make sure Rcpp is installed there too . It is a setup issue . In other words it should work if you have Rcpp and RInside installed where the basic R libraries are .

Why would I install Node.js manually to use npm to then be able to install Node.js using n To put my question in other words : Why does n suggest installing using npm if its main purpose is to install Node.js which includes npm .. . Answer : The n module was created for convenience . For example if you wanted to update your version of Node.js from v0.8.0 to v0.10.20 would you rather download a package extract and compile Or would you rather type n 0.10.20 and have it instantly installed while still retaining previous versions of Node for easy switching n suggests using npm to install it because n is a module . That is npm is the easiest way to install it . Node modules have the functionality of being able to run in a shell when installed globally so that function was utilized to make switching Node versions much easier . Comment : Of course you are right that it s much more convenient to just type n 0.10.20 and you re done but why not use n for the initial install This way the very first install feels special . E.g . : Is it guaranteed that n uses the same folders as the Node.js installer does Comment : Because n is a module and using npm is simply the easiest way to install it . As for your second question Node.js binaries are stored in n s own directory something like usr local n versions otherwise you wouldn t be able to have multiple versions installed at the same time . Comment : But the initial install isn t installed there - isn t that a problem Please forgive me if this questions may be a little naive but I just wonder why it is and I m curious - Comment : Why would it be a problem if the initial install isn t there Comment : I m not sure about the initial install but for most cases n prev would just restore the previous version . Edit : It appears it also saves the initial install to usr local n versions .prev when you first add a new version as it does with any installation . Therefore n prev would also work in restoring the initial install .", "Question : I have a problem understanding the use of n https : github.com visionmedia n .

I want to use it for my first android application . However I have a question - if my app will be implemented using Android N tools using Java 8 features but with settings minimal sdk 4.1 will my application work on Android 4 5 6 Comment : I want to use it for my first android application -- that is not a good idea IMHO . Wait until Android N ships in final form presumably Android 7.0 in a few months . Comment : I m new to android and it s mostly for learning . But my personal phone running Android 5 so I need to know - will my app will work on it or no . Comment : Not right now . Apps compiled against the N Developer Preview will only run on N Developer Preview devices unless you take some fairly nasty and complicated steps to try to work around that restriction . That is one of the reasons why I suggest that you wait on using Android N until it ships in final form . Comment : thanks for clarification . .. . Answer : Yes your app will work on previous versions of Android if you use the Support Libraries . These are updated with new versions of Android to provide backwards compatibility to new features . This is a common practice . https : developer.android.com topic libraries support-library index.html .. . .. . For Java 8 it sounds like you will need to be selective in what you use . From the documentation : https : developer.android.com preview j8-jack.html .. . .. . Supported Java 8 Language Features and APIs Android does not currently support all Java 8 language features . However the following features are now available when developing apps targeting the Android N Preview : .. . .. . Default and static interface methods .. . .. . Lambda expressions also available on API level 23 and lower .. . .. . Repeatable annotations .. . .. . Method References also available on API level 23 and lower .. . .. . Note : To test lambda expressions and method references on earlier versions of Android go to your build.gradle file and set compileSdkVersion and targetSdkVersion to 23 or lower . You will still need to enable the Jack toolchain to use these Java 8 features . Comment : The OP s app will not work on previous versions of Android until Android N ships in final form unless the OP takes significant steps . Once you specify that you are compiling and targeting N your app s minSdkVersion is raised to N and your app will only run on N Developer Preview devices . Beyond that I am personally a bit hazy as to what portions of the Java 8 support will be backwards compatible or not and little of that will necessarily be covered by the Android Support libraries . Comment : in this artice mentioned that support libraries mostly used to fix lacking of API . But in my case it wil be next language version . Are you sure it s fit for that case Comment : sounds like it s going to be a mixed bag for Java 8 . If you want to make sure your app is backwards compatible you are going to have to be selective in what your use . Looks like Lambdas and Method References are already useable on previous versions but other features are not .

Answer : Since you didn t indicate whether you want word or character-level n-grams I m just going to assume the former without loss of generality . I also assume you start with a list of tokens represented by strings . What you can easily do is write n-gram extraction yourself . Then replace the yield with the actual action you want to take on each n-gram add it to a dict store it in a database whatever to get rid of the generator overhead . Finally if it s really not fast enough convert the above to Cython http : cython.org and compile it . Example using a defaultdict instead of yield : Comment : The newer versions of Cython recognize Python for statements and speeds them up if possible . Further you have a method lookup in the inner iteration . defining tokenjoiner .join outside the loop and replacing the inner .join should speed things up .

Answer : I can t comment directly on other answers because I don t have enough reputation . But it s worth noting that the problem essentially only arises because historically a lot of dbms have been quite poor when it comes to handling joins MySQL being a particularly noteworthy example . So n+1 has often been notably faster than a join . And then there are ways to improve on n+1 but still without needing a join which is what the original problem relates to . However MySQL is now a lot better than it used to be when it comes to joins . When I first learned MySQL I used joins a lot . Then I discovered how slow they are and switched to n+1 in the code instead . But recently I ve been moving back to joins because MySQL is now a heck of a lot better at handling them than it was when I first started using it . These days a simple join on a properly indexed set of tables is rarely a problem in performance terms . And if it does give a performance hit then the use of index hints often solves them . This is discussed here by one of the MySQL development team : .. . .. . http : jorgenloland.blogspot.co.uk 2013 02 dbt-3-q3-6-x-performance-in-mysql-5610.html .. . .. . So the summary is : If you ve been avoiding joins in the past because of MySQL s abysmal performance with them then try again on the latest versions . You ll probably be pleasantly surprised . Comment : Upvoted you should be able to comment now Comment : Calling early versions of MySQL a relational DBMS is quite a stretch.. . If people encountering those problems had been using a real database they would not have encountered those kinds of problems . - Comment : Interestingly many of these types of problems were solved in MySQL with the introduction and subsequent optimization of the INNODB engine but you ll still run into people trying to promote MYISAM because they think it s faster .", "Question : The problem is often mentioned in object-relation mapping discussions and I understand that it has something do to with having to make a lot of database queries for something that seems simple in the object world .

Answer : Suppose you have COMPANY and EMPLOYEE . COMPANY has-many EMPLOYEES i.e . EMPLOYEE has a field COMPANY ID . In some O R configurations when you have a mapped Company object and go to access its Employee objects the O R tool will do one select for every employee wheras if you were just doing things in straight SQL you could select from employees where company id XX .

It s odd that this particular effect would be device-specific but . I do not have NDP3 loaded on a 5X so I cannot confirm the behavior . I recommend that you file a bug report on this whether using my sample project or one of your own .

If you are ok with just disable paste action here is a method : .. . .. . add UITextFieldDelegate to you view controller and implement method like this .. . .. . it means that if user enter more than one character for each action it means that probably user is pasting something . do not accept it in textfield . it is a good practice for force user enter textfields like e-mail and Comment : still can paste 1 character . Comment : Best solution for this hands down Comment : canPerformAction does work in IOS 5.1 . The problem is your dealing with the canPerformAction in the delegate class .

But there is an idea . I think the method canPerformAction were called for many times but you just deal with it once . In this case I think there may be another UI Control has called it . For example the UITextView control in your UIWebView . I guess you may generate the UI by storyboard . Not every control in storyboard has its own class . You can define a class for the response control and rewrite its canPerformAction method .

Answer : 1 you need to add custom menu items to the shared UIMenuController : .. . .. . 2 you need to implement your handler methods somewhere in the responder chain for the view that will be first-responder when you show the menu : .. . .. . 3 you optionally need to implement canPerformAction : in the responder chain for the view that will be first-responder when you show the menu : .. . .. . 4 if the view you want to present the menu for doesn t already support showing a menu i.e . a UIWebView will show a menu when the user does a long-tap but a UILabel has no built-in support for showing a menu then you need to present the menu yourself . This is often done by attaching a UILongPressGestureRecognizer to the view then showing the menu in the callback : .. . .. . Note there has to be a view that claims firstResponder for the menu to show . 5 make sure the view you re showing the menu for returns YES TRUE to canBecomeFirstResponder . For example if you try to make a UILabel a first responder it will return NO so you would have to subclass it . 6 that s about it . You may want to resignFirstResponder when the action callback is called - but to do this you ll need to implement logic to discover the firstResponder .

Answer : phpMyAdmin uses SHOW TABLE STATUS to get information for your tables . From the documentation http : dev.mysql.com doc refman 5.1 en show-table-status.html : .. . .. . Rows .. . .. . The number of rows . Some storage-engines such as MyISAM store the exact count . For other storage-engines such as InnoDB this value is an approximation and may vary from the actual value by as much as 40 to 50 . In such cases use SELECT COUNT to obtain an accurate count . This is due to InnoDB being an ACID http : en.wikipedia.org wiki ACID compliant storage engine .

I m considering .. . .. . 1 . Convert 5 write-intensive tables to use InnoDB engine and keep the rest on MyISAM engine .. . .. . 2 . Convert all tables to use InnoDB engine . I wonder which approach is better To be more specific .. . .. . The reason I want to keep some table on MyISAM engine is some of them has around 1 000 000 rows . I m not sure how slower it will be for queries like SELECT COUNT on these tables after converted to InnoDB . I haven t done a test . I prefer getting some advices from any of you before start the switch . Comment : Why not have the best of the two worlds : MySQL PBXT .. . Answer : These days I always default to using InnoDB especially on the write-intensive tables you mention where MyISAM suffers from full table locking . Here s a to-the-point comparison . Reasons to use MyISAM : .. . .. . Tables are really fast for select-heavy loads .. . Table level locks limit their scalability for write intensive multi-user environments . Smallest disk space consumption .. . Fulltext index .. . Merged and compressed tables . Reasons to use InnoDB : .. . .. . ACID transactions .. . Row level locking .. . Consistent reads allows you to reach excellent read-write concurrency . Primary key clustering gives excellent performance in some cases . Foreign key support . Both index and data pages can be cached . Automatic crash recovery in case MySQL shutdown was unclean InnoDB tables will still - recover to the consistent state- No check repair like MyISAM may require . All updates have to pass-through transactional engine in InnoDB which often decreases - performance compared to non-transactional storage-engines . The above was taken from this site which no longer seems to be working . Comment : Your follow up concern regarding COUNT is well-founded . InnoDB does not keep an internal count of rows in a table so performing a SELECT COUNT does do a full table scan . Whereas such a query would require no time with MyISAM an equivalent InnoDB query could take many seconds for 1mil rows . The typical solution is to maintain another counter table where you would manually increment and decrement depending on whether you inserted or removed a countable row .

As expected the select was very fast 70 segs and all other selects like count distinct customer from where almost instantaneous . Just for curiosity I tried to continue the process of inserting the distances in the myisam table . It was a surprise for me when the program started to run at least 100 times faster than when it was working on the innodb table -for INSERTS For each customer the program inserts something like 3000 rows one for each neighbor for each product type .

So in summary the question is : Why is MyISAM that fast with insert statements What do you think EDIT 1 : I m adding the create statements for both tables the innodb and myisam . EDIT 2 : I deleted some unuseful information and formated a little bit here and there . Comment : Were the tables otherwise identical indexes etc.. . And there are separate server settings such as memory cache sizes for the engines that could affect performance . Comment : You should normalise the product sales data . The table doesn t make much sense as presently designed . Comment : Identical tables same servers . Comment : Questions about performance normally need a CREATE for all relevant tables and an EXPLAIN Comment : You won t convince me that denormalizing the data like this and doubling or tripling the size of a table with 50 million rows is really going to make your reports run significantly faster .

Inno DB When to use MyISAM and InnoDB http : stackoverflow.com questions 15678406 when-to-use-myisam-and-innodb Comment : Thank you for the information and the comparison . What you are suggesting is that MyISAM is faster on this case because it doesn t have all those controls . Those controls are intended to manage multiple connections so if I had multiple connections to the database It wouldn t be faster Comment : Multiple connections hitting the same table will be slower in MyISAM because of the table level locking as opposed to row level locking .", "Question : I am working on a project for which we are required to use transaction journaling in our DBMS MySQL . We have already switched to using InnoDB in order to use transactions for another requirement . I am trying to understand what transaction journaling is . I have been searching for over a day now including reading through MySQL documentation . Maybe I am just not searching for the right keywords I am not sure . Or maybe transaction journaling is inappropriate terminology . From what I understand database transaction journaling is similar to a journaling file system in that changes are made to a journal before they are committed to the file system . From what I ve read it sounds like the InnoDB engine stores transactions in some kind of journal before they are committed to disk . Does this sound accurate If so where is the transaction journal Is it ib logfile0 and ib logfile1 .. . Answer : You are definitely on the right track here . Whenever InnoDB does a transaction that has to be committed it is done as a two-phase commit . Transaction is written in these logs first . Then they are committed from there . This helps a great deal in the event of the MySQL crash or server crash . When you restart mysql all uncommitted entries in ib logfile0 and ib logfile1 are replayed as part of the crash recovery of InnoDB to bring InnoDB to a harmonious state This is Consistent and Durable parts of ACID Compliance http : en.wikipedia.org wiki ACID .. . .. . If you delete ib logfile0 and ib logfile1 and start mysql any uncommitted transaction that those files contained are lost . During the crash recovery cycle if the log files are missing they are regenerated based on the innodb log file size http : dev.mysql.com doc refman 5.5 en innodb-parameters.html sysvar innodb log file size setting . Please see the MySQL Documentation for a detailed explanation of InnoDB http : dev.mysql.com doc refman 5.5 en innodb-storage-engine.html . @karatedog the MVCC part of InnoDB happens within the system tablespace better known as ibdata1 . Whatever data appear to be before the start of a transaction is recorded to allow others who access the needed rows to have a view of the data before any updates were imposed . This is allows for what is called a REPEATABLE-READ . This falls under the I of ACID compliance I meaning Isolation . I wrote posts about this in the DBA StackExchange in regard to various scenarios where transaction isolation is good bad or ugly . read before write transaction http : dba.stackexchange.com a 14058 877 .. .

It crashes rather easily http : dba.stackexchange.com a 15079 877 . That s why the SQL command REPAIR TABLE exists . That s is also why the MySQL utility myisamchk has the -r option to perform REPAIR TABLE for MyISAM tables that are not online . MariaDB and Aria http : kb.askmonty.org en aria-faq have been attempts to make a crash-safe storage engine as a replacement for MyISAM . Comment : I understand that these log files are for crash recovery but isn t the MVCC mechanism responsible for a transaction to happen properly when no crash occurs MyISAM has some degree of crash recovery while it does not have transactions at all . Comment : Thank you for your detailed and timely response . I am a little confused about replaying the entries in the logs . If there was a failure in the middle of a transaction before the commit was issued I would think you wouldn t want to replay the entries since transactions are all-or-nothing you wouldn t want a portion of the transaction to be committed . Or are you saying they would be replayed only if there was a commit but the failure occurred before the transaction was committed to the database but after it was saved in the log files", "Question : Someone just told me that InnoDB is much better than MyISAM .

Answer : InnoDB is a fully ACID compliant database engine and therefore offers support for transactions etc . As such it can therefore be slower than the MyISAM database which tends to be optimised in a different direction .

Answer : Storage engines are MySQL components that handle the SQL operations for different table types . InnoDB is the default for v5.7 and most general-purpose storage engine . MySQL storage-engines include both those that handle transaction-safe tables and those that handle nontransaction-safe tables . MySQL Supported Storage Engines .. . .. . 1 . InnoDB http : dev.mysql.com doc refman 5.7 en innodb-storage-engine.html : InnoDB is a transaction-safe ACID compliant storage engine for MySQL that has commit rollback and crash-recovery capabilities to protect user data . InnoDB row-level locking without escalation to coarser granularity locks and Oracle-style consistent nonlocking reads increase multi-user concurrency and performance . InnoDB stores user data in clustered indexes to reduce I O for common queries based on primary keys . To maintain data integrity InnoDB also supports FOREIGN KEY referential-integrity constraints . For more information about InnoDB see Chapter 14 The InnoDB Storage Engine . 2 . MyISAM http : dev.mysql.com doc refman 5.7 en myisam-storage-engine.html : These tables have a small footprint . Table-level locking limits the performance in read-write workloads so it is often used in read-only or read-mostly workloads in Web and data warehousing configurations . 3 . Memory http : dev.mysql.com doc refman 5.7 en memory-storage-engine.html : Stores all data in RAM for fast access in environments that require quick lookups of non-critical data . This engine was formerly known as the HEAP engine . Its use cases are decreasing InnoDB with its buffer pool memory area provides a general-purpose and durable way to keep most or all data in memory and NDBCLUSTER provides fast key-value lookups for huge distributed data sets . 4 . CSV http : dev.mysql.com doc refman 5.7 en csv-storage-engine.html : Its tables are really text-files with comma-separated values . CSV tables let you import or dump data in CSV format to exchange data with scripts and applications that read and write that same format . Because CSV tables are not indexed you typically keep the data in InnoDB tables during normal operation and only use CSV tables during the import or export stage . 5 . Archive http : dev.mysql.com doc refman 5.7 en archive-storage-engine.html : These compact unindexed tables are intended for storing and retrieving large amounts of seldom-referenced historical archived or security audit information . 6 . Blackhole http : dev.mysql.com doc refman 5.7 en blackhole-storage-engine.html : The Blackhole storage engine accepts but does not store data similar to the Unix dev-null device . Queries always return an empty set . These tables can be used in replication configurations where DML statements are sent to slave servers but the master server does not keep its own copy of the data . 7 . NDB http : dev.mysql.com doc refman 5.7 en mysql-cluster.html also known as NDBCLUSTER : This clustered database engine is particularly suited for applications that require the highest possible degree of uptime and availability . 8 . Merge http : dev.mysql.com doc refman 5.7 en merge-storage-engine.html : Enables a MySQL DBA or developer to logically group a series of identical MyISAM tables and reference them as one object . Good for VLDB environments such as data warehousing . 9 . Federated http : dev.mysql.com doc refman 5.7 en federated-storage-engine.html : Offers the ability to link separate MySQL servers to create one logical database from many physical servers . Very good for distributed or data mart environments . 10 . Example http : dev.mysql.com doc refman 5.7 en example-storage-engine.html : This engine serves as an example in the MySQL source code that illustrates how to begin writing new storage-engines . It is primarily of interest to developers . The storage engine is a stub that does nothing . You can create tables with this engine but no data can be stored in them or retrieved from them . You are not restricted to using the same storage engine for an entire server or schema . You can specify the storage engine for any table . For example an application might use mostly InnoDB tables with one CSV table for exporting data to a spreadsheet and a few MEMORY tables for temporary workspaces .

Answer : MyISAM .. . .. . The MyISAM engine is the default engine in most MySQL installations and is a derivative of the original ISAM engine type supported in the early versions of the MySQL system . The engine provides the best combination of performance and functionality although it lacks transaction capabilities use the InnoDB or BDB engines and uses table-level locking . FlashMAX and FlashMAX Connect : Leading the Flash Platform Transformation Download Now Unless you need transactions there are few databases and applications that cannot effectively be stored using the MyISAM engine . However very high-performance applications where there are large numbers of data inserts updates compared to the number of reads can cause performance proboelsm for the MyISAM engine . It was originally designed with the idea that more than 90 of the database access to a MyISAM table would be reads rather than writes . With table-level locking a database with a high number of row inserts or updates becomes a performance bottleneck as the table is locked while data is added . Luckily this limitation also works well within the restrictions of a non-transaction database . MyISAM Summary .. . .. . Name -MyISAM .. . .. . Introduced -v3.23 .. . .. . Default install -Yes .. . .. . Data limitations -None .. . .. . Index limitations -64 indexes per table 32 pre 4.1.2 Max 16 columns per index .. . .. . Transaction support -No .. . .. . Locking level -Table .. . .. . .. . .. . InnoDB .. . .. . The InnoDB Engine is provided by Innobase Oy and supports all of the database functionality and more of MyISAM engine and also adds full transaction capabilities with full ACID Atomicity Consistency Isolation and Durability compliance and row level locking of data . The key to the InnoDB system is a database caching and indexing structure where both indexes and data are cached in memory as well as being stored on disk . This enables very fast recovery and works even on very large-data sets . By supporting row level locking you can add data to an InnoDB table without the engine locking the table with each insert and this speeds up both the recovery and storage of information in the database . As with MyISAM there are few data types that cannot effectively be stored in an InnoDB database . In fact there are no significant reasons why you shouldn t always use an InnoDB database . The management overhead for InnoDB is slightly more onerous and getting the optimization right for the sizes of in-memory and on disk caches and database files can be complex at first . However it also means that you get more flexibility over these values and once set the performance benefits can easily outweigh the initial time spent . Alternatively you can let MySQL manage this automatically for you . If you are willing and able to configure the InnoDB settings for your server then I would recommend that you spend the time to optimize your server configuration and then use the InnoDB engine as the default .

Answer : InnoDB offers : .. . .. . In InnoDB all data in a row except for TEXT and BLOB can occupy 8 000 bytes at most . No full text indexing is available for InnoDB . In InnoDB the COUNT s when WHERE GROUP BY or JOIN is not used execute slower than in MyISAM because the row count is not stored internally . InnoDB stores both data and indexes in one file . InnoDB uses a buffer pool to cache both data and indexes . MyISAM offers : .. . .. . MyISAM has table-level locking but no row-level locking . No transactions . No automatic crash recovery but it does offer repair table functionality . No foreign key constraints . MyISAM tables are generally more compact in size on disk when compared to InnoDB tables . MyISAM tables could be further highly reduced in size by compressing with myisampack if needed but become read-only . MyISAM stores indexes in one file and data in another . MyISAM uses key buffers for caching indexes and leaves the data-caching management to the operating-system . Overall I would recommend InnoDB for most purposes and MyISAM for specialized uses only . InnoDB is now the default engine in new MySQL versions . Comment : fwiw VARCHAR in InnoDB can also go to overflow pages like BLOB and TEXT do . All these data types are stored similarly internally .

Answer : myisam is a NOGO for that type of workload high concurrency writes i dont have that much experience with innodb tested it 3 times and found in each case that the performance sucked but it s been a while since the last test if you re not forced to run mysql consider giving postgres a try as it handles concurrent writes MUCH better", "Question : A co-worker just made me aware of a very strange MySQL behavior . Assuming you have a table with an auto-increment field and another field that is set to unique e.g . a username-field . When trying to insert a row with a username thats already in the table the insert fails as expected . Yet the auto-increment value is increased as can be seen when you insert a valid new entry after several failed attempts . For example when our last entry looks like this.. . .. . .. . ...and we try five new entries with the same username value on our next insert we will have created a new row like so : .. . .. . While this is not a big problem in itself it seems like a very silly attack vector to kill a table by flooding it with failed insert requests as the MySQL Reference Manual states : .. . .. . The behavior of the auto-increment mechanism is not defined if .. . the value becomes bigger than the maximum integer that can be stored in the specified integer type . Is this expected behavior Comment : Your attack vector seems a non issue . If you could flood it with failed insert requests couldn t you equally flood it with non failed requests Comment : can you bring a reproduce code instead of manual explanations Comment : @martin smith : While thats true I think a sudden surge of new users would be more obvious than a silent increase in the auto-increment that might very well fall by the wayside if not checked for . .. . Answer : InnoDB is a transactional engine . This means that in the following scenario : .. . .. . 1 . Session A inserts record 1 .. . 2 . Session B inserts record 2 .. . 3 . Session A rolls back .. . .. . there is either a possibility of a gap or session B would lock until the session A committed or rolled back . InnoDB designers as most of the other transactional engine designers chose to allow gaps . From the documentation http : dev.mysql.com doc refman 5.5 en innodb-auto-increment-handling.html : .. . .. . When accessing the auto-increment counter InnoDB uses a special table-level AUTO-INC lock that it keeps to the end of the current SQL statement not to the end of the transaction . The special lock release strategy was introduced to improve concurrency for inserts into a table containing an AUTO INCREMENT column .. . .. . .. . .. . InnoDB uses the in-memory auto-increment counter as long as the server runs . When the server is stopped and restarted InnoDB reinitializes the counter for each table for the first INSERT to the table as described earlier .

Answer : A bit late to the game...but here s a quite comprehensive post I wrote a few months back http : blog.danyll.com myisam-vs-innodb detailing the major differences between MYISAM and InnoDB . Grab a cuppa and maybe a biscuit and enjoy . .. . .. . The major difference between MyISAM and InnoDB is in referential-integrity and transactions . There are also other difference such as locking rollbacks and full-text searches . Referential Integrity .. . .. . Referential integrity ensures that relationships between tables remains consistent . More specifically this means when a table e.g . Listings has a foreign key e.g . Product ID pointing to a different table e.g . Products when updates or deletes occur to the pointed-to table these changes are cascaded to the linking table . In our example if a product is renamed the linking table s foreign-keys will also update if a product is deleted from the Products table any listings which point to the deleted entry will also be deleted . Furthermore any new listing must have that foreign key pointing to a valid existing entry . InnoDB is a relational DBMS RDBMS and thus has referential-integrity while MyISAM does not . Transactions Atomicity .. . .. . Data in a table is managed using Data Manipulation Language DML statements such as SELECT INSERT UPDATE and DELETE . A transaction group two or more DML statements together into a single unit of work so either the entire unit is applied or none of it is . MyISAM do not support transactions whereas InnoDB does . If an operation is interrupted while using a MyISAM table the operation is aborted immediately and the rows or even data within each row that are affected remains affected even if the operation did not go to completion . If an operation is interrupted while using an InnoDB table because it using transactions which has atomicity any transaction which did not go to completion will not take effect since no commit is made . Table-locking vs Row-locking .. . .. . When a query runs against a MyISAM table the entire table in which it is querying will be locked . This means subsequent queries will only be executed after the current one is finished . If you are reading a large table and or there are frequent read and write operations this can mean a huge backlog of queries . When a query runs against an InnoDB table only the row s which are involved are locked the rest of the table remains available for CRUD operations . This means queries can run simultaneously on the same table provided they do not use the same row . This feature in InnoDB is known as concurrency . As great as concurrency is there is a major drawback that applies to a select range of tables in that there is an overhead in switching between kernel threads and you should set a limit on the kernel threads to prevent the server coming to a halt . Transactions Rollbacks .. . .. . When you run an operation in MyISAM the changes are set in InnoDB those changes can be rolled back . The most common commands used to control transactions are COMMIT ROLLBACK and SAVEPOINT . 1 . COMMIT - you can write multiple DML operations but the changes will only be saved when a COMMIT is made 2 . ROLLBACK - you can discard any operations that have not yet been committed yet 3 . SAVEPOINT - sets a point in the list of operations to which a ROLLBACK operation can rollback to .. . .. . Reliability .. . .. . MyISAM offers no data integrity - Hardware failures unclean shutdowns and canceled operations can cause the data to become corrupt . This would require full repair or rebuilds of the indexes and tables . InnoDB on the other hand uses a transactional log a double-write buffer and automatic checksumming and validation to prevent corruption . Before InnoDB makes any changes it records the data before the transactions into a system tablespace file called ibdata1 . If there is a crash InnoDB would autorecover through the replay of those logs . FULLTEXT Indexing .. . .. . InnoDB does not support FULLTEXT indexing until MySQL version 5.6.4 . As of the writing of this post many shared-hosting providers MySQL version is still below 5.6.4 which means FULLTEXT indexing is not supported for InnoDB tables . However this is not a valid reason to use MyISAM . It s best to change to a hosting provider that supports up-to-date versions of MySQL . Not that a MyISAM table that uses FULLTEXT indexing cannot be converted to an InnoDB table . Conclusion .. . .. . In conclusion InnoDB should be your default storage engine of choice . Choose MyISAM or other data types when they serve a specific need . Comment : So great explanation Thanks @danyll", "Question : Below is the ammount of rows for 2 tables in my mysql DB .. . 1 is myisam the other innodb .. . .. . can someone tell me why the innodb one has this in front of the number These numbers came from phpmyadmin .. . Answer : Because InnoDB is a transactional storage engine the exact count is subject to interpretation . For example some rows may exist in storage but the transaction that created those rows has not committed yet . So the rows should not be included in the count . Even more confusing your transaction may be REPEATABLE READ isolation-level which means only rows that were committed before your transaction began are visible . Some rows may be committed but more recently than the start of your repeatable read transaction . So those rows also should not be included in the count . But the same rows are included in a count done by another transaction that was started later or in READ COMMITTED isolation-level . This is why this table statistic for InnoDB can only be approximated . An accurate count requires a scan of all stored rows to see if they are visible to the current transaction .", "Question : When i run Select from table on an INNODB table does the table get locked implicity Does it mean that during the time MySQL takes to return the result set i cannot issue an update statement on the table From what i have understood the whole table would be locked in shared mode until the result set is returned from the server . Only then could the update command be executed . Comment : What happened when you tried Comment : Haven t tried . Just asking for the sake of knowledge . Comment : Have edited the question . .. . Answer : InnoDB uses a feature called Multi-version concurrency control https : en.wikipedia.org wiki Multiversion concurrency control . Locking in shared mode is not required since MVCC will retain earlier versions of the row for your SELECT statement to be able to read if required . So the answer is no running a SELECT statement will not need to lock any rows while updating . That is unless it is a special SELECT statement like SELECT . . FOR UPDATE . Comment : Thanks for clarifying .", "Question : When I execute a query in MySQL it returns an error saying that InnoDB is not enabled . When I clicked the storage engine the InnoDB was disabled . How do I enable InnoDB .. . Answer : You need to enable it in my.cnf file then restart your server : .. . .. . http : dev.mysql.com doc refman 5.1 en innodb-parameters.html option mysqld innodb .. . .. . Or you can load an InnoDB plugin during runtime : .. . .. . http : dev.mysql.com doc refman 5.1 en replacing-builtin-innodb.html Comment : Do you also need to convert individual tables to use InnoDB if they were created when a different storage engine was default Comment : Yes you do need to do that .", "Question : I m working on a projects which involves a lot of database writes I d say 70 inserts and 30 reads . This ratio would also include updates which I consider to be one read and one write . The reads can be dirty e.g . I don t need 100 accurate information at the time of read . The task in question will be doing over 1 million database transactions an hour . I ve read a bunch of stuff on the web about the differences between MyISAM and InnoDB and MyISAM seems like the obvious choice to me for the particular database tables that I ll be using for this task . From what I seem to be reading InnoDB is good if transactions are needed since row level locking is supported . Does anybody have any experience with this type of load or higher Is MyISAM the way to go Comment : The MySQL Performance Blog http : www.mysqlperformanceblog.com s MyISAM+InnoDB is a great resource for this type of thing . Comment : This would depend a bit on whether you re system is OLTP or more datawarehouse oriented where most of the writes are bulk loading .

Answer : If you use MyISAM you won t be doing any transactions per hour unless you consider each DML statement to be a transaction which in any case won t be durable or atomic in the event of a crash . Therefore I think you have to use InnoDB . 300 transactions per second sounds like quite a lot . If you absolutely need these transactions to be durable across power failure make sure your I O subsystem can handle this many writes per second easily . You will need at least a RAID controller with battery backed cache . If you can take a small durability hit you could use InnoDB with innodb flush log at trx commit set to 0 or 2 see docs for details you can improve performance . There are a number of patches which can increase concurrency from Google and others - these may be of interest if you still can t get enough performance without them ." ] }

Answer : The Oracle site says that you can complete the steps in any order but you must complete all prerequisite steps to achieve certification at the current level .

Question I m referring to is from Self Test Chapter 5 Question 9 page 455 of the PDF . I answered CDF . The correct answer according to the book was DF .

The answer C stated might throw a StackOverflowError so I knew C was correct . If I m wrong can anybody explain why Comment : This for is an endless loop . Why would it cause StackOverflowError Does it take up more and more of the stack every iteration Comment : Endless or even finite with high-bound recursive call results an Stack Overflow not a loop . Comment : Offtopic but you do know that PDF is for sun certified java programmer certification which doesn t exist anymore as such Oracle split that into two distinct certifications . .. . Answer : Since in that loop you re not actually calling methods that need to call other methods a la recursion you re not adding more calls to the stack . You re merely repeating the steps you did most every time through . Since a StackOverflowError http : stackoverflow.com a 214758 1079354 is only invoked in certain conditions - namely the calling of another method which would call more methods or the allocation of more elements onto the stack then there s really no way that this particular loop could cause such an error .

B object has both A.x and B.x variables . However instance methods with the same signature are overridden not hidden and you cannot access the version of a method that is overridden from the outside .

How exactly does String.split method in Java work when regex is provided questions 22259733 how-exactly-does-string-split-method-in-java-work-when-regex-is-provided 1 answer .. . .. . I was doing a question out of the book oracle certified professional java se 7 programmer exams 1z0-804 and 1z0-805 by Ganesh and Sharma . One question is : .. . .. . 80 . Consider the following program and predict the output : .. . .. . class Test .. . .. . public static void main String args .. . String test I am preparing for OCPJP .. . String tokens test.split S .. . System.out.println tokens.length .. . .. . .. . .. . .. . a 0 .. . .. . b 5 .. . .. . c 12 .. . .. . d 16 .. . .. . Now I understand that S is a regex means treat non-space chars as the delimiters . But I was puzzled as to how the regex expression does its matching and what are the actual tokens produced by split . I added code to print out the tokens as follows .. . .. . and I got the following output .. . .. . So a lot of empty string tokens . I just do not understand this . I would have thought along the lines that if delimiters are non space chars that in the above text then all alphabetic chars serve as delimiters so maybe there should be 21 tokens if we are matching tokens that result in empty strings too . I just don t understand how Java s regex engine is working this out . Are there any regex gurus out there who can shed light on this code for me Comment : I tried your example and it makes much more sense if you replace S with s could this be a typo Comment : @mreiterer This is for a certification exam why would it seem strange that they throw in a tricky case like this The fact that they included the correct answer 16 as one of the choices makes it very unlikely that this was unintentional . Comment : P.S . If 21 had been one of the choices I probably would have gotten this wrong . Comment : Hi no it was meant to be S the opposite of s . Tricky one this . .. . Answer : First things start with s lower case which is a regular expression character-class for white space that is space tabs t new line chars n and r vertical tab v and a bunch of other characters . S upper case is the opposite of this so that would mean any non white space character . So when you split this String I am preparing for OCPJP using S you are effectively splitting the string at every letter . The reason your token array has a length of 16 . Now as for why these are empty . Consider the following String : Hello World if we were to split that using we would end up with a String array of length 2 with the following contents : Hello and World . Notice that the is not in either of the Strings it has be erased . The same thing has happened with the I am preparing for OCPJP String it has been split and the points matched by your regex are not in any of the returned values . And because most of the letters in that String are followed by another letter you end up with a load of Strings of length zero only the white space characters are preserved . Comment : The point of the questions is : why 16 and not 21 Why is OCPJP not treated as a bunch of separators There are 21 letters but last ones are ignored.. .

Is it a case of the JVM ignoring the getObject part and always taking x from c1 as variables are associated at compile-time Comment : Having typed the code up why not run it and see that it returns 5 Comment : i also see that it will return 5 not 6 .. . Answer : Although the override is done properly for SubCovariantTest the answer is 5 because of how the variable c1 is declared . It is declared as a CovariantTest and not as a SubCovariantTest . When c1.getObject .x is run it does not know that it is a SubCovariantTest no casting was used . This is why 5 is returned from CovariantTest and not 6 from SubCovariantTest .

Each should perform differently regardless of knowing the subclass or needing to cast to it . Comment : Yes but fields are not polymorphic in Java . Only methods are .

Answer : The reason the result is 16 and not 21 is this from the javadoc for Split http : docs.oracle.com javase 8 docs api java lang String.html split-java.lang.String- : .. . .. . Trailing empty strings are therefore not included in the resulting array . This means for example that if you say .. . .. . the result will have five elements . The first will be since it s not a trailing empty string the others will be abc def and ghi . But the remaining empty strings are removed from the array . In the posted case : .. . .. . it s the same thing . Since non-space characters are delimiters each letter is a delimiter but the OCPJP letters essentially don t count because those delimiters result in trailing empty strings that are then discarded .

Answer : There are raw video and audio streams this streams cannot be played directly on most video audio-player they need to be encapsulated on a transport a raw H.264 video stream and a raw AAC audio stream need to be inside a MP4 encapsulator it can be also inside an AVI or MOV encapsulator .

Does anyone have a pointer to MediaCodec examples to decode AAC files without using MediaExtractor to generate the format object Comment : Further investigation has lead me to believe that csd-0 contains the ESDS Elementary Stream Descriptor . Looking at MakeAACCodecSpecificData in avc utils.cpp in the Android sources I see that the first 5 bits are the object-type 2 the next 4 are the frequency index 4 48000 the next 4 are the channel config 2 . This wiki page http : wiki.multimedia.cx index.php title Understanding AAC indicates that the remaining bits are for frame length depends on core decoder and extension flag . I m using MediaFormat.createAudioFormat which should setup the important elements of the ESDS . .. . Answer : I had no issues decoding playing AAC content on the few devices I tested . My approach was to use the MediaExtractor first to set the Data source then initialise the MediaFormat and finally do the work in a loop with buffers sent in out to from the MediaCodec . For the surface I used null as this is just an audio-player so there is nothing to display .

I m talking about files that end .aac not AAC audio inside M4A or MP4 containers . I m aware Netstream can t parse ADTS headers etc so I already have a class for parsing the data and gives back correct info such as channels bitrates framelengths etc . Putting this together gives silence : Make FLV header + append - Make audio tag header + append - now append with raw headerless AAC payload frame 1 + update previous tag size - Make new audio tag for next AAC frame append - raw headerless payload append frame 2 and so on until track end . Can someone please clarify : .. . .. . In the FLV tag we put extra byte to specify whether Raw or Sequenced AAC type . If I have removed the 7 byte header and left with only data up the next frame SyncWord . I assume its Raw but I get silence whichever setting I choose . Should I be considering anything else ie an additional function depending on type Should AAC header bytes exist in some data at some point sent to the Appendbytes command Even if I already set FLV tag to Raw AAC audio Do all AAC files hold 1024 samples per frame regardless of channels or should I multiply 1024 by channels number I ask because I need this for correct duration calculation and noticed when testing MP3s that I get silence if duration or framelengths are wrong . I have a lot of questions and a lot research AAC specs FLV specs etc but nothing is helping and there is some confused info on the net well they don t always speak from an AS3 perspective. . . I guess I just need to know it s definitely possible rather than keep on blindly against a technical limitation .. . .. . PS : I have succesfully played .MP3 audio files with AppendBytes and now changed the process to accomodate AAC ie : parsing 7 byte header not 4 byte header etc . More to it than that ofcos . Thanks for reading and hope someone out there can help . .. . Answer : I meant to answer this a while back.. . Working Demo. . A very basic demo of AAC file playback http : www.swfcabin.com swf-files 1411416171.swf see below if you need some test AAC file .. . .. . I can happily confirm that it s 100 possible to play an .aac audio file using NetStream . So to clarify my own questions : .. . .. . You need both AAC types mentioned at first to kickstart the AAC decoder then afterwards you can do the usual FLV tag with AAC type : Raw + Raw AAC data no ADTS header and continue as such until track end . Nope . No ADTS bytes should be sent to the Netstream decoder . Yes every AAC frame contains 1024 samples and each frame is equal to 23.21 milisecs around 44 frames for 1 second of audio . Channel settings are irrelevant . The image below illustrates the process . As you can see after the FLV header metadata there is tags for BOTH types at first but afterwards its AAC type raw for the rest of the way . No ADTS means remove the 7 byte header from each AAC frame and shove what s left into FLV tags . I made one FLV audio tag per AAC frame easier to deal with seeking timestamps etc .. . enter image description here http : i.stack.imgur.com uEnha.jpg .. . .. . After analysing a test FLV made with FFMPEG inside a Hex editor I understood to use both settings . I don t how they figured out you needed both instead of either one or other like the FLV Specs ver 10.1 was suggesting . I bow my head to the genius of those guys girls . I was stuck because of this : enter image description here http : i.stack.imgur.com dSLXO.jpg .. . .. .

What does the optimize option do to the audio Is it re-encoding it or just packing it differently Most importantly what do I need to do in order to read the audio track correctly I ve been searching for some months now but no one seems to have a technically useful answer to this i.e . anything beyond It makes the files smaller . This appears to only affect the audio track if I disable audio decoding the video plays back just fine in all cases at least all I ve seen so far - Apple tools ffmpeg commercial encoders etc . .. . Answer : Ok so after some experimenting I think I ve found the answer to my question . Normally AAC frames are packed such that a small whole number of AAC frames fit within a single Payload Unit roughly interleaved in PTS order with the video frames they synchronize with . These Payload Units are then packed into the payload space of consecutive 188 byte TS Packets with the empty space in the last TS Packet padded with junk i.e . not part of the data-stream . This can mean that in a 10 second TS segment you might have an overhead in the order of roughly 2-6 Kbytes . With AAC optimization two things appear to change . 1 . The size of the Payload Units containing the AAC frames is increased reducing overall the number of Payload Units . 2 . The Payload Units are sized to an exact multiple of the payload space in a TS Packet rather than to fit an number of whole AAC frames . This means that padding is all but eliminated - All used space is valuable data so the overall size is reduced . In addition this means that AAC frames are no longer immediately adjacent to the video frames they should sync with - They may be some considerable distance apart in fact . This also means however that an individual Payload Unit may not be able to fit a whole AAC frame at the end so as much of the frame as will fit is put in this Payload Unit and the rest is put at the beginning of the next AAC Payload Unit - This means that AAC Payload Units may not start with AAC frame sync bytes Which is what I was seeing Wherever either the read AAC frame is not long enough to contain a whole header or where the AAC payload length in the AAC header is less than remaining Payload Unit length then the remaining data must be in the next AAC Payload Unit - Note however this may be in the next segment", "Question : As I understand it Android will only play AAC format audio if it s encoded as MPEG-4 or 3GPP .

It simply downloads the file and plays from the cache . Comment : Good idea but of course this requires the entire file to be downloaded first before it can be played . Could be useful for some situations but obviously not suitable as a streaming solution .

Also what is your bit-depth setting 8bit or 16bit audio Comment : Hi Thanks for the reply I tried with 16000 the result is same . I am using 16bit audio . .. . Answer : What documentation says that HE-AAC supports 8 kHz sampling rate There s also a difference between the standard itself supporting it and this particular encoder supporting it . In practice HE-AAC uses a technique called sideband replication SBR . This boils down to that the main AAC stream itself is of the half sample rate and then the higher sample rate is reconstructed on top of this . If you d encode 8 kHz audio in this way the main AAC stream would be 4 kHz and I m not sure if the encoder actually supports that . Therefore HE-AAC mostly makes sense if you have got a high sample rate - it doesn t make much sense to try to use it for a 8 kHz audio stream .", "Question : null .. .

I have read here https : wiki.blazegraph.com wiki index.php InferenceAndTruthMaintenance that Blazegraph can use rules but I d like to get SWRL working with Blazegraph . Is it possible Comment : There s no mention of SWRL support on their website . Comment : Is SPARQL and option If so the SWRL rule can be written and executed using SPARQL . Comment : Then wouldn t the SPARQL query have to be triggered every time someone inputs the triple : someInstance : hasSampleLocale : tag retail", "Question : How can I connect to a triple store and access an ontology through the RDFLib Python API The triple store I am using is Blazegraph . I know how to access Virtuso but about Blazegraph I am not sure . .. . Answer : You probably want to access the triple store via SPARQL with SPARQLWrapper http : rdflib.github.io sparqlwrapper .", "Question : I am doing some experiments with the Blazegraph Nano SPARQL Server . I started the server with the following command : .. . .. . However I need to set a timeout for queries . There is a context parameter named queryTimeout http : wiki.blazegraph.com wiki index.php NanoSparqlServer web.xml for that but I do not know how it has to be used . Can I add a command option to set this parameter If this parameter can only be set in a web.xml file where can I find a minimal web.xml file that I can use to set the queryTimeout parameter .. . Answer : It is possible to compile Blazegraph again after updating the web.xml file . The steps are : .. . .. . Clone the git repository . Checkout the release . Edit bigdata-war src WEB-INF web.xml to set the queryTimeout property as : .. . .. . Recompile Blazegraph .", "Question : I have a file data.nq containing the following lines : .. . .. . In the same directory there is blazegraph.jar using version 2.1.0 and a file p.properties with the following content : .. . .. .

I do the same but setting the quads mode off . That is setting the following property in p.properties : .. . .. . In this case I get no error but also no named graphs in the dataset . How can I load quads using the bulk loader Update : I found an explanation for this error in the Blazegraph documentation https : wiki.blazegraph.com wiki index.php REST API Context Not Bound Error .28Quads mode without defaultGraph.29 . It says that I have to set the property defaultGraph in the properties file . Thus I have added the following line to the properties file : .. . .. . However I got the same error . .. . Answer : It is required to add defaultGraph as an option in the command-line not in the properties file . Thanks to people that help me to answer this question in the Blazegraph mailing list . Comment : I m new to semantic data what does the defaultGraph mean how does it relate to the imported N-Quad data Comment : Also how are N-Quad s 4-columns consumed structured within the triple store after import i.e . is ALL the data from the 4 columns available if so how is it queried structured re-constructed from SPO-triples" ] }

Answer : The presence of Ajax4jsf 1.x specific org.ajax4jsf . classes in the stacktrace tells that you re still using Ajax4jsf for JSF 1.x . This is not compatible with JSF 2.x . You must remove all Ajax4jsf 1.x related JAR files and registrations in web.xml . You need to use JSF s own f : ajax facilities instead or to upgrade to RichFaces 4.x which bundles a newer JSF 2.0 compatible version of a4j : xxx tags .

Is there any elegant way like ui : repeat to do it in jsf-1.2 .. . Answer : The only JSF 1.2 component http : docs.oracle.com javaee 5 javaserverfaces 1.2 docs tlddocs which can iterate over a List is the h : dataTable http : docs.oracle.com javaee 5 javaserverfaces 1.2 docs tlddocs h dataTable.html . In JSP the only other standard i.e . not 3rd party tag which can iterate over a List is the JSTL c : forEach http : docs.oracle.com javaee 5 jstl 1.1 docs tlddocs c forEach.html . Using JSTL shouldn t harm that much if the List which you d like to iterate over is already available during view build time . You ll only run into trouble when it s only available during view render time for example because it s been nested in a h : dataTable and should be iterating over a property of table s var . This just won t work due to reasons also mentioned in JSTL in JSF2 Facelets.. . makes sense http : stackoverflow.com questions 3342984 jstl-in-jsf2-facelets-makes-sense 3343681 3343681 .. . .. . There are no other ways without using a 3rd party library such as Tomahawk s t : dataList unless you re open to reinventing the wheel by creating a custom UIComponent yourself . This is however not a trivial job . It s however possible to integrate Facelets 1.x in JSF 1.2 . A guide is described in the Facelets 1.x docbook http : facelets.java.net nonav docs dev docbook.html . This is only going to be quite some of work if you already have an existing JSF application using JSP as view technology you d need to convert JSP to Facelets . But it ll in end make the upgrade path to JSF 2.x so much easier . See also a.o .

Why oh why am I trapped in JSF 1.2 Comment : @nvy : you need a h : column to specify a table column . Also unlike in Facelets you can t use deferred EL in template text in JSP so you should really use h : outputText for the abc .

Answer : Not much really . JSF 1.2 is 100 backwards compatible with JSF 1.1 . Only thing which you need to take into account that JSF 1.2 fixes many really many bugs . So if you ever incorrectly assumed some specific JSF 1.1 application behavior as normal behavior but which is under the covers actually caused by a bug then it would seemingly break . In any case just run unit tests before and after the upgrade and fix the issues individually . It s only migrating from JSF 1.x to 2.x which requires more work for sure if you also need to change the view technology from JSP to Facelets .

E.g return welcome.xhtml redirect-faces true Comment : Or you can do save in actionListener and have action welcome.xhtml redirect-faces true Comment : @Mahendran : nothing in the question implies that OP is using JSF 2.x . Moreover reRender attribute implies RichFaces 3.x which strongly suggests JSF 1.x . The jspx tag on question only confirms JSF 1.x more as JSP is deprecated in JSF 2.x and no one sane developer would use it in JSF 2.x . Better ask OP which JSF version exactly he is using before suggesting JSF 2.x specific solutions . Comment : @BalusC oh thanks . My inexperience in richfaces is showing . So I am thinking aloud here . So h : outputLink or navigation case .. . Answer : The simplest way : Just return your welcome page full path on your consultDossier.save method . Comment : OP asked to perform a redirect not a forward . Comment : I do Agree with BalusC and I would like to manage this through my jspx", "Question : Before I get started with my question here are my unfortunate limitations : .. . .. . 1 . I m using JSF 1.2 not 2 so no composite-component . 2 . I m using JSP for rendering instead of facelets so none of those composite components either . 3 . I m not allowed to use any 3rd-party tag libraries richFaces iceFaces etc . These limitations are set in stone . Now moving onto my question . Currently we have a JSP subview which handles creating an address . There is a lot of javascript that goes along with this along with a backing bean . This page is never used directly . Instead it s included using a jsp : include . However there are several attributes that I want to be able to change . For instance is county required are we currently doing address scrubbing etc . In order to do this it would make sense to use a custom component I think . However I m not really sure the best way to do this . If I could I would simply turn this JSP into a composite-component and be done with it . However that s not really an option based on my limitations . What are my options This wouldn t be so difficult if it weren t for the amount of javascript involved . I know my explanation was vague however I m looking more for guidance than a direct answer . I ve googled for things such as custom JSF 1.x components with javascript etc . I haven t found many good articles however . Thanks in advance . Comment : Sounds like they expect you to pick fly poop out of pepper while wearing boxing gloves . Been there . It sounds like you want to add custom validations on form fields . The real question is why does a jsp : include forgo this What will a custom component bring to the table other than your ability to learn how to write a custom component under the JSF1.2 spec which IMHO is broken Comment : If it were only so easy No validation is done using JSF validators . Not even defining the required attribute . They don t want to change that . There are many other customizations that need done beyond validation . For example each address can be attached to a different contact whose contactId contact table s PK needs defined up front . There s also display logic : can this address be a legal address -- one defined using lat long -- instead of a mailing address . Comment : @Zack.. .

Answer : I have seen in JSF 2 that it is possible to pass parameters to method calls . Is there anything equivalent in JSF 1.2 .. . .. . Passing parameters to method calls is not specific to JSF 2 . It is specific to EL 2.2 which is in turn part of JSP 2.2 Servlet 3.0 Java EE 6 . JSF 2 just happens to be part of Java EE 6 as well . In other words if you deploy your JSF 1.2 web application to a Servlet 3.0 compatible container like Tomcat 7 Glassfish 3 etc and your web.xml is declared conform Servlet 3.0 spec version then it ll just work out the box for JSF 1.x as well . If you re however still targeting a container of an older Servlet version then you need to supply a different EL implementation which supports invoking methods with arguments . One of those implementations is JBoss-EL http : docs.jboss.org seam 2.0.0.GA reference en html elenhancements.html which you can install by just dropping the jboss-el.jar https : maven.atlassian.com content repositories jboss-releases org jboss-seam jboss-el 2.0.0.GA jboss-el-2.0.0.GA.jar file in WEB-INF lib of your webapp and adding the following context parameter to the web.xml .

Answer : Mojarra is the reference implementation of the Oracle JSF 1.x 2.x spec .", "Question : My Question is related to jsf . I am trying to make a jsf dataTable with radio buttons . For e.g . In the first row there are 5 columns : The first column has a question and rest 4 are radio buttons . : I want the user to select only one radio-button out of the 4 in a single row and repeat the same process for all the rows . I have read the following link where a javascript code is given for selecting one row using radio-buttons : How to group Radio Buttons in h : datatable jsf2.0 http : stackoverflow.com questions 7146625 how-to-group-radio-buttons-in-hdatatable-jsf2-0 and http : www.javabeat.net how-to-use-hselectoneradio-inside-hdatatable-in-jsf .. . .. . But my requirement is to select one of the radio-button in a row .. . .. . I got some clue here : http : www.javaworld.com article 2077687 enterprise-java group-radio-buttons-inside-a-jsf-datatable-component.html but I would rather prefer a javascript code to do this activity rather than going for a custom tag if possible.Or if there is another way to do the same in pure jsf . Edit : .. . .. . Code in jsp : .. . .. . JS : .. . .. . The problem is that each radio-button in the consecutive rows have the same value for radio.name.substring radio.name.lastIndexOf : but the radio buttons in the same row doesn t have the same name as I checked in View Source of browser . So how to overcome that . Comment : If you have tried it show the code you have worked with it ll help identify what mistake you may be making . Comment : @ miqdadamirali I added the code .. . Answer : The name of the radio buttons generated in html by jsf in the first row are : j id jsp 2000213722 8 : 0 : rad1 j id jsp 2000213722 8 : 0 : rad2 j id jsp 2000213722 8 : 0 : rad3 and j id jsp 2000213722 8 : 0 : rad4 .. . .. . Similarly the name of the radio buttons generated in html by jsf in the second row are : j id jsp 2000213722 8 : 1 : rad1 j id jsp 2000213722 8 : 1 : rad2 j id jsp 2000213722 8 : 1 : rad3 and j id jsp 2000213722 8 : 1 : rad4 .. . .. . So we can see the string after last colon in the name rad1 rad2 rad3 signifies that the column is different and the integer after the first colon 0 1 2 signifies that the row is different but they are same for every radio-button in the same row . So my logic will be that no two radio buttons with name i.e . 0 or 1 or 2 should be checked at the same time . So I changed my script code as follows to extract that 0 or 1 or 2 for each row : .. . .. . My requirement is that it should allow me to select radio buttons simultaneously in different rows but not in the same row in the first row all radio buttons have the name 0 in second 1 in third 2 and in fourth row the value of name is 4 . So I am taking that part of name which is same for a row i.e . the part after the first colon so that according to the logic it will allow only one radio-button to be checked with that name and it will uncheck all other radio buttons with the same name except the one checked . So this logic works for me .", "Question : I m currently migrating a JSF-1.2 app to Wildfly 8 Final and am stuck : .. . .. . First of all I ve read many post with related issues e.g . https : community.jboss.org message 845006 or Migrate JSF 1.2 Seam app to WildFly Beta 1 http : stackoverflow.com questions 19843066 migrate-jsf-1-2-seam-app-to-wildfly-beta-1 but the proposed solution excluding the weld subsystem doesn t work for me . What I did : .. . .. . .. . I followed the multi-jsf feature tutorial here https : community.jboss.org wiki StepsToAddAnyNewJSFImplementationOrVersionToWildFly and installed JSF 1.2 as a module for wildfly to be exact 3 modules . The next was that I added exclusions for javax.faces.api and com.sun.jsf-impl main slots as well as the corresponding dependencies to the 1.2 slots to my jboss-deployment-structure.xml for my war . Since the app is using Tomahawk and Tomahawk Sandbox which I am also deploying with my ear I also excluded the main slots and included the 1.2 slots of both modules for these deployments . My problem : .. . .. . .. . When I try to call the initial page of the deployment login.xhthml I get the following error which is caused by the module org.jboss.as.jsf-injection in slot 1.2 .. . .. . The error is caused by the ConversationAwareViewHandler which is contained in the jar weld-core-jsf-2.1.2.Final.jar in module org.jboss.as.jsf-injection which I also installed with the JSF 1.2 modules . This Class still references JSF 2.2 API and fails accordingly . Excluding the weld subsystem from tomahawk and my war did also not work . I tried this : .. . .. . What can I do else .. . Answer : To make it short this problem is caused by an incompatibility of weld and JSF 1.2 that won t be fixed in future releases see here https : issues.jboss.org browse WFLY-3215 . In my opinion there are three ways one can go : .. . .. . 1 . Upgrade your application code to work with JSF 2.x . 2 . Exclude the weld subsystem where necessary will likely require reconfiguring the default-cdi settings of wildfly . 3 . Patch the class ConversationAwareViewHandler appropriately to act differently in case of the old JSF API . For me there was only the option to patch the JSF-injection module since an application upgrade was not possible and option 2 would require a larger restructuring of the application . Comment : Very well stated . I found out the following post access.redhat.com solutions 1273803 https : access.redhat.com solutions 1273803 which shows a way of configuring weld to use JSF 1.2 slot .

Answer : You seem to be trying to use JSF 1.2 with Facelets 1.x . That s fine but the Facelets view handler is missing in faces-config.xml . You should have the following entry in there : .. . .. . Note that you need the jsf-facelets.jar http : mavenhub.com mvn thirdparty-releases com.sun.facelets jsf-facelets 1.1.15 file for this . Also note that you actually don t need to provide JSTL http : stackoverflow.com tags jstl info along with your webapp WebSphere 7 as being a full fledged Java EE 5 application server already provides it by itself . I recommend to remove those JSTL JAR files as it might possibly conflict with the ones provided by WebSphere . JSF is also already provided by WebSphere but Facelets not as that is only part of Java EE since Java EE 6 . Given the lack of Facelets view handler I wonder if you re reading the right Facelets tutorial since JSF 2.0 a Facelets view-handler configuration is not mandatory as it s the default view handler already so perhaps you were accidently reading a JSF 2.0 targeted tutorial while you should really be reading the one for JSF 1.x so for the sake of completeness here s a link-to the official developer guide of Facelets 1.x http : facelets.java.net nonav docs dev docbook.html .", "Question : I am working on JSF 1.x On an example stated in JavaServer Faces in Action .

Pyjamas widgets are mostly same as GWT s most are direct translation from GWT but we have some own widgets too and do not target Qt GTK or any other toolkit . If you are looking into using webkit you could get best of the two worlds and use Pyjamas with PyJD .

Answer : I am working on a .NET application that uses Python for its internal scripting-language IronPython . We now have a goal of generating HTML pages using the information that users have created using the application . Ideally when we export to HTML we would be able to bring over the functionality our users have written in their Python scripts . I am thinking that one option might be to automatically translate the Python script to JavaScript using something like Pyjamas http : pyjs.org . I am not a Python expert or JavaScript expert . From skimming through the documentation for Pyjamas I am getting the impression that Pyjamas itself is written in Python . So to embed the functionality of Pyjamas inside our software I think I would need to include all of the Pyjamas source files in my software and then execute them using IronPython .

For example YouTube is in Python -- where do you see that affecting its performance scalability or big money characteristics Is pyjamas mature enough to replace GWT on a performance and functionality point of view Completely different question from the previous silly observation . GWT has been around for longer and has more users and contributors . Perhaps pyjamas is good enough for many uses -- nevertheless it is at release 0.7 with GWT at release 2.0 which can be taken as an indication that GWT is better more developed and mature .

Is it plausible for a Python-syntax fan to use one of these options while other team members plain vanilla version Is it a matter of personal preference or would it require converting other people to using these technologies as well 2 . Is it possible to easily convert between say Jython and Java or Pyjamas and Javascript 3 . Also in general what advantages disadvantages have people experienced from using these in the real world I think that states a little more clearly what I m looking for . Input from anyone who uses these technologies in the industry would be very helpful . Thanks in advance for your insights . Comment : It s not just syntax . Syntax is mere visuals . .. . Answer : You are talking about two different things . First Jython and IronPython are Python implementations that you can embed in a Java or C application to provide scripting capability . This reduces the amount of code that you have to write overall . Or you can look at them as a way to glue together and leverage an existing collection of class libraries . However you look at it these are good things and lots of people use them . But Pyjamas is something else entirely . It complicates your web stack and makes it harder to pass projects on to other programmers . The main use-case is if you have a shop of Python programmers and they need to provide a rich Internet application-client side but cannot afford the time to learn Javascript . Not as broadly useful . Also my personal experience is that most Python programmers already know Javascript reasonably well from building web apps . It really is not much of a learning curve to just dive into Javascript . I ve written JSCRIPT scripts on Windows as a batch-file replacement and bits of Javascript with Jquery in numerous web pages . When I wanted to learn server-side Javascript for node.js it really only took a couple of weeks to round out my knowledge of Javascript . In my opinion Pyjamas should be avoided . Sooner rather than later Javascript engines will be supporting version 1.8 of the language which greatly narrows the gap between the languages other than the curly-braces issue .", "Question : I have one design decision to make . In my web ajax application we need to decide where should we put user-interface logic Should It be completely loaded via javascript pure single page . and Only data comes and go . or .. . .. . Should server send some format XML which translated via javascript to dynamically create rich user-interface . semi-ajax . so some data and ui comes and go . Which option is better speed ease of development platform independence .. . .. . Thanks . .. . Answer : I faced similar dilemma few months back . As Lennart above says it makes sense to go for pyjamas or similar library if your app is more desktopish . Further one of the biggest advantage of pyjamas provide is logically well separated backend and frontend code . IMO that is very important . If your app is not like a desktop app like ours was then multipage offers more advantages such as single change wont breaks entire app easier to maintain etc . You might want to consider can have your app server serve json and other web server serves static content and js . Js would request json app server for data . That way we managed to keep out frontend and backend separate . Further we chose mootools as js lib over pyjamas . Ofcourse it is upto your taste and need of application . We did use python template server-side templates but at compile-time not at runtime like usual approach . This needed to change our thinking a little but the offered many advantages . I end up telling you my story but I thought it s relevant and hope that helps .", "Question : null .. . Answer : I am trying to get scipy working with pyjamas .

Concurrent access to a stream object 27.8 27.9 stream buffer object 27.6 or C Library stream 27.9.2 by multiple threads may result in a data race 1.10 unless otherwise specified 27.4 . Note : Data races result in undefined-behavior 1.10 . end note .. . .. . In the general case streams are not safe to use across threads .

Consider this line : .. . .. . which is the same as .. . .. . Note the race-condition . Let s say that your implementation s operator for streams is synchronized for you by the implementation . You still have a potential race in this outer code . For instance here is one possible execution of this across 2 threads : .. . .. . Instead of getting that to write as a single line you ll get output from each thread mixed up together resulting in gibberish . Comment : that was a typo in editing for the post it is myfile matchSet.testCase corr.match corr.editDistance n - your race-condition is exactly what happens when it crashes - I can see the garbled output in the outfile . But when one thread opens the file then the other thread should see it as open and pause in the while-loop Comment : @forest : No . Why would you expect it to pause Those are 5 completely separate IO operations they may be interleaved in any order unless you use locks to enforce otherwise . As for the is open check if your streams implementation is not synchronized there is no guarantee that opening the file on one thread will update the state and flush CPU caches and such for a thread running on a different CPU . It d be very easy for both threads to end up inside the if file.is open check for instance . Comment : @Billy ONeal yes I understand that intuition and common sense has no place in c++ but if I open an ofstream then pass references to it down a dozen paths any change on each of those paths is referencing the same ofstream so it seems like in this sense as far as each thread is concerned they are one thread . If thread 1 has ofstream xyz open then thread 12 is referencing the exact same ofstream xyz so no need to update or flush anything . Pragamtically this logic is clearly wrong but it seemed logical.. . Comment : @forest : That s not a C++ thing that s a parallelism in general thing . Why would you expect 5 completely independent function-calls to be executed as an atomic operation without any form of synchronization Why would you expect mutable shared data such as ostream s format or error condition flags to be thread safe without synchronization I know of no language which would obey your asserted logic .

Is there a better way to reserve use of an ofstream shared by multiple threads .. . Answer : If you are new to multi-threading then let this be a lesson in why you should use mutex locks . The fstream object is just that - an object . You must protect it against simultaneous access by using a mutex . If you just want threads to be able to write information to a file you could instead pass a file name as a string instead of an fstream . The thread could then open the file with exclusive read-write access . This would use a local fstream object and the locking would be handled by the operating-system .

Comment : In your current code you can do this : filelist.push back filelist 0 which makes the pushed back pointer point at the same file stream as the first pointer . .. . Answer : You need either an ostream or ostream . filelist i is a shared-ptr ostream which you can in this case think of as basically an ostream . This means that filelist i gives you an ostream via the operator http : en.cppreference.com w cpp memory shared-ptr operator 2a overload .

But also the interleaving problem where multiple lines are written at the same time should be avoided . The question was simply how to lock-out a ofstream that was being used by multiple threads so only one has access to it at a time . .. . Answer : Something like that However it is usually better to implement operator as a free function rather than class member . Comment : That appears to work fine although for some reason it cannot accept std : : endl Comment : What do you mean by cannot accept Comment : I can any const strings including those with a n character but if I put stream std : : endl the program aborts . It also aborts if I try stream.flush . Taking some time trying to figure out why .

For some reason the file is empty however the contents of buf is never empty.. . What am I doing wrong Comment : I think we d need to see the calling code too maybe you can strip this down to a compilable example Also don t use manual allocation like that . : Change your buf stuff to std : : vector char buf n + 1 and : : vsprintf buf 0 fmt varptr and for outputting std : : copy buf.begin buf.end std : : ostream iterator char ofstr . And of course no need to delete anymore . Also you don t need to call ofstr.close the destructor does that anyway . Comment : have you checked permissions on the log file Comment : @GMan : Wouldn t std : : string fit the need even more than std : : vector char Comment : @GMan : thanks for the tips so the copy is done to write to the ofstream Comment : @GMan : Thanks for the explanations . Makes sense . .. . Answer : You need to flush the ofstream before closing it . Try ofstr.flush before ofstr.close I had this error some time ago when I thought that closing the stream automatically flushes it but as it turned out it doesn t . Comment : I m pretty sure it should perhaps that was a bug in your implementation . But maybe I m wrong I ll look . Comment : @GMan : Did you look into it Do tell us if you find any thing interesting Comment : Ah yeah . It is indeed the case close flushes the stream and that close is called by the destructor . 27.8 . 1.2 3 describes the destructor of a basic filebuf and says that it calls close . 27.8 . 1.3 6 describes the closing procedure which includes flushing the stream . And of course the file streams all have the same behavior as owning a basic filebuf as a member meaning when they destruct the basic filebuf does leading to the previous effects .", "Question : I am having the worst time trying to make a class that has a std : : ofstream and a std : : mutex that is locked and unlocked to control access to the ofstream .

Also note the std : : ostream operator std : : ostream const T http : en.cppreference.com w cpp io basic ostream operator ltlt2 operator is explicitly reserved for text formatted output not to write binary-data .

The C++ standard-library has no notion how to magically interact with binary .zip files .

Answer : It is usually a bad idea to restrict a function to std : : ofstream when it may as well work with any kind of std : : ostream .

Answer : You can create gtkbuilder files with the glade interface designer at least with newer versions round about 2 years . In your application the one you write compile use the GtkBuilder object to load the widget-tree from the file . .glade is just a different afaik format to store the widget-tree . As of now I d recommend Gtk+ 3.x - from my personal experience things are a lot more thought out and less evolutionary read : backwards compat cruft is kept . As long as the target has a somewhat recent which has GtkBuilder support glib gtk+ library you should be fine . gtk+ is multiplatform and GtkBuilder is part of it - nothing gnome specific .

Answer : It may not be possible . The way to approach it would be to write a shim library in C that uses libmono to interoperate with your C widgets . Here is a link-to Mono s documentation on how to do that . http : www.mono-project.com docs advanced embedding The entry-point into your shim library would then be listed in the init-function element in the Glade catalog . Alternatively you can fake the widget classes in the Glade catalog their properties and signals will appear though you have to manually write them in the catalog file . If they are container widgets you won t be able to add child widgets to them . They ll just appear as grey boxes in Glade .

Is it true Furthermore it seems for UI generation MonoDevelop uses Stetic which extends Glade . Which one should I use .. . Answer : There is a difference between Glade the application and libglade the library . Libglade is a library that has been replaced by GtkBuilder and so you should not use it . Glade the application is the UI designer which can save GtkBuilder files or libglade files for compatibility . Stetic ties in with Mono and MonoDevelop a bit more and so if you use MonoDevelop then you should probably use Stetic . Comment : Thanks for explanations .

Comment : Welcome to Stack Overflow You asked this question 17 minutes ago as of writing this comment . Stack Overflow is a website not everyone is looking at it at all hours so you will need to be patient to get an answer . Anyway glade files are just what the UI looks like . You need to write some code using the GTK+ toolkit to use the glade file . You can use C or any other language you like . The class you use to load the glade file into GTK+ 3 is GtkBuilder .

You ll have to recreate the GUI from scratch sorry . .. . Answer : There is no way to reverse assemble a C++ file into a Glade file . Consider three reasons this is so : .. . .. . C++ is much more versatile than Glade . It has so much flexibility that to ask a piece of software to cram it into an inflexible format like Glade would be nearly impossible . The software to do this would have to be as big as Glade itself . There s a lot of pain no gain . What do you gain by reverse assembling it C++ is already the more flexible platform Glade is only made available for people who don t want to do all their layout dynamically in code . If you already have code in C++ you re better off than if you were just given Glade files to work with . C++ wouldn t be the first choice of language to do this with . If there was such a thing it would be released natively for C first . Since there is no such tool for C I think we can be sure there is no such tool for C++ a language for which GTK+ must use a binding . My advice : stick with your C++ files .

Answer : The glade-3.8.x series is the last version supporting Gtk+2 . glade 3.8.x targets Gtk+3 . Ubuntu provides the glade-gtk2 package which packages the 3.8.x version whereas the glade package packages the latest Gtk+3 only version . So if you are targeting Gtk+2 you need to install glade-gtk2 and use that version of glade .

Thanks Comment : If you run glade from the terminal you might see it the output it prints to the terminal what is causing it to crash . You could then open the glade file with a text-editor and remove the offending elements properties . The problem is most likely that the new glade wrote elements properties to the file which glade 3.8.x cannot read causing it to crash because of poor error-handling .

My impression is that it s common practice to create a subclass of GtkWindow for your main window but I m stuck on how I would construct my subclass from a GtkBuilder definition . Does anyone know how Comment : Have you looked at library.gnome.org devel gtk stable GtkBuilder.html http : library.gnome.org devel gtk stable GtkBuilder.html Could you clarify exactly what your objective is here .. . Answer : Subclassing GtkWindow is more common in GTK s various language bindings than it is in plain C . You didn t mention which language you were using . That said the way I subclass GtkWindow in C is to create the contents of the window in Glade but not the window itself . In Glade 3 IIRC you can right-click on a widget in the palette and choose Add widget as toplevel to place a non-toplevel widget without a container . Then write code for your subclass of GtkWindow let s call it MyAppWindow . I won t go into that in this answer since there are plenty of examples in the GObject documentation . In the init function my app window init load the Glade file use gtk builder get object to get a pointer to the outermost widget in the Glade file and use gtk container add to add it to the window you are constructing . Then use gtk builder connect signals as you normally would . You have to set all the window s properties manually this way since you can t do it in Glade but other than that I ve found it works quite well . Comment : That seems good . I ve been studying the GNOME sources to get an idea of how they do it and they do subclass GtkWindow . I m not sure if they use the technique you outlined though . Comment : Which applications are you looking at I sometimes look at Gedit for examples of how to do things but it is huge . Comment : I usually look at Gedit too . As it turns out though Gedit doesn t actually use GtkBuilder -- in fact I m pretty sure none of the standard GNOME apps do . Which I think explains my confusion -- I expected that anyone in their right mind would want to use GtkBuilder . Comment : GtkBuilder is relatively new so older applications would have to port legacy code to use it . Also it s probably more useful for simple applications with a static interface.. .

If you have an error it means you re probably not using the right bindings . pygtk is no more used it s gobject-instrospection that is used with GTK 3 . So don t use in your python code the import pygtk but instead : from gi.repository import Gtk . Read these links : live.gnome.org PyGObject https : live.gnome.org PyGObject and python-gtk-3-tutorial.readthedocs.org en latest http : python-gtk-3-tutorial.readthedocs.org en latest Comment : It s just that for GTK 3 the old pyGTK bindings have been replaced by new bindings that use pyGObject . The introspection features of GObject help in the bindings maintenance which was more difficult in pyGTK .", "Question : I want to create some popover widget using only glade : is it possible I mean speaking of popover : some window that shows when clicking on a button and that disappears when clicking elsewhere . I tried a lot of things I read a lot of things on the internet but I found nothing that is strange in my sense . Comment : GTK+ 3.12 adds GtkPopover . More recent versions of glade should have that available try 3.18 Comment : @andlabs I am on glade 3.19 but I cannot see any GtkPopover widget . But I will search everywhere . Comment : @andlabs it seems the support is only from glade 3.20 : compatdb.org forums topic 111487-glade-3200-released http : www.compatdb.org forums topic 111487-glade-3200-released Comment : @andlabs I installed the last version and here it is Thank you very much . You can post it as an answer and I will accept it . .. . Answer : Glade 3.20 adds support for GtkPopover which itself was added in GTK+ 3.12 . You ll have to be careful about making sure your generated .ui files are backward compatible which includes going in and checking the header of the file . Comment : After creating a GtkPopover you need to create a GtkMenuButton and then you have to select the popover in its use-popover property . Comment : That s only if you want to use a popover with a GMenu . You don t have to do that a popover is just a GtkBin so it can contain anything just like a normal window . Comment : Yes but only the GtkMenuButton has the use-popover property . I could not find another way to show the popover using only glade . Comment : Oh yes you need to connect your UI elements using code somehow . Glade doesn t define behavior only appearance . It can take advantage of GModule features to hook up signals by function name but other than that :" ] }

Comment : Do not install packages using sudo pip - that is highly discouraged because of various problems associated with this approach . Instead follow the Python community best practices and create virtual environments for installing your packages : packaging.python.org en latest https : packaging.python.org en latest installing.html creating-virtual-environments Comment : @MikkoOhtamaa I m not installing it using sudo pip . Comment : You should use sudo to access that directory . You can try changing the permission with chmod 755 to allow permission to your user . But what distro and what package are you installing Comment : @TatakaiWasumi my own . Comment : @MarioHonse : No sudo in whatever context when installing Python packages . Please create virtual environments and sudo is not needed for installing anything . .. . Answer : I installed my own package via sudo python setup.py install locally . Once you used sudo which you should not do all files that your package includes are owned by root because its the root user that is running setup.py install . Now when you try to run any module that is included in the package as your normal user and that module tries to open modify read create any directory or file that is part of the package itself it will run into permission problems . All files for your package are owned by root and you are trying to run it with your normal user and that user cannot create directories in the package s source path which is referred to here os.path.dirname os.path.realpath file . The solution to your problem is to first uninstall the module you can simply delete the entire tree as root . Next as your normal user create a virtual environment and install your package . This will make sure that : .. . .. . 1 . Your package isn t installed in the global Python package repository . 2 . Files for your package are owned by your normal user account . 3 . Any file-level operations can be performed properly without using elevated permissions like sudo . Now if you need to create these directories as part of your package s setup procedure then you need to modify your setup.py .", "Question : I have a python program and I want to get the path to the program from within the program but INCLUDING the file name itself .

Answer : Just in case you would like to find the absolute path for other files not just the one you are currently running in that same directory a general approach could look like this : .. . .. . As others are mentioning you could take advantage of the file attribute . You can use the file attribute to return several different paths relevant to the currently loaded Python module copied from another StackOverflow answer http : stackoverflow.com a 9271479 5209610 : .. . .. . When a module is loaded in Python file is set to its name . You can then use that with other functions to find the directory that the file is located in . Remember to be wary of where the module you are loading came from . It could affect the contents of the file attribute copied from Python 3 Data model documentation https : docs.python.org 3 reference datamodel.html : .. . .. . file is the pathname of the file from which the module was loaded if it was loaded from a file .

However when I check the Volatile GPU Util using nvidia-smi -l 1 I notice that it s only 6 and I think most of the computation is on CPU since I notice that the process which runs Tensorflow has about 90 CPU usage . The result is the training process is very slow . I wonder if there are ways to make full usage of GPU instead of CPU to speed up the training process . Thanks .. . Answer : I suspect you have a bottleneck somewhere like in this github issue https : github.com tensorflow tensorflow issues 838 -- you have some operation which doesn t have GPU implementation so it s placed on CPU and the GPU is idling because of data transfers . For instance until recently reduce mean was not implemented on GPU and before that Rank was not implemented on GPU and it was implicitly being used by many ops . At one point I saw a network from fully connected preloaded.py https : github.com tensorflow tensorflow blob master tensorflow examples how tos reading data fully connected preloaded.py being slow because there was a Rank op that got placed on CPU and hence triggering the transfer of entire dataset from GPU to CPU at each step . To solve this I would first recommend upgrading to 0.8 since it had a few more ops implemented for GPU reduce prod for integer inputs reduce mean and others . Then you can create your session with log device placement True and see if there are any ops placed on CPU or GPU that would cause excessive transfers per step . There are often ops in the input pipeline such as parse example which don t have GPU implementations I find it helpful sometimes to pin the whole input pipeline to CPU using with tf.device cpu : 0 : block Comment : Thanks for your great answer After I did some profiling work I noticed that tensor.eval session .. . feed dict .. . takes too much time and the time consumption grows as code running time goes by .

Second when you only need to train CNN with small datasets e.g 2M images you can just use ImageDataLayer same as @kli nlpr said . Finally just like @Shai said the most challenge of all process always is preparing data and check training whether the outcome is what you expected if it is not you should check data preparing data again or check training configuration .

Comment : I posted all the solutions to the problem that I found in the thread .. . Answer : The difference in architectures between CPU and GPU does not allow simple transformation of the code written for one architecture to the other . The GPU drivers are specifically written for the GPU architecture and cannot be easily virtualized . On the other hand some software supports both . This includes OpenGL instructions and caffe http : caffe.berkeleyvision.org .

Answer : AFAIK there is no straight forward way of doing so . However you can use net surgery https : github.com BVLC caffe blob master examples net surgery.ipynb to load the pretrained models and manually assign their weights to the target net . Once you have a single net with all the weights initialized according to the various pretrained models you can save it and use it as a single pretrained model for the rest of your work . Comment : this is how to do it...a NN model is just a bunch of weights so all you need to do is copy them over and save it . good luck though...if you copy layers from different nets they may not play well together .

Do I need to remove OpenCV and reinstall Caffe and Digits If so what do I need to do differently to prevent the OpenCV version conflicts while still allowing Caffe with OpenCV 3 and Digits to work side-by-side .. . Answer : When OpenCV library is installed the shared-libraries are stored like libopencv core.so.2.4.8 where 2.4.8 is the version number of OpenCV . libopencv core.so file usually links to the last version of OpenCV installed in the system . Thus though libopencv core.so was initially linked to libopencv core.so.3.0 when you installed the older version the link got updated to link-to the older version . The workaround will be to specifically call the latest OpenCV library in caffe . To do so you will have to modify the Makefile present in caffe .

However when I try to run it it appears to not like the format of the mean.binaryproto file as indicated by the error message : .. . .. . what am I doing wrong here Do I need to process the mean.binaryproto file from Digits somehow before I use it with caffe .. . Answer : You need to convert the .binaryproto file to a numpy file . There is a nice example here https : github.com BVLC caffe issues 290 using caffe.io and caffe.proto .", "Question : null .. . Answer : I have installed and compiled caffe BVLC version . It works well . Now I want to install DIGITS . I have installed all the dependancies for DIGITS too . I want to install it on my Mac . So I do not have GPU and I need to run it only using CPU . in the installation it says : I have 2 modes to use DIGITS : 1- Development mode 2- production mode .. . .. . using the first mode : I should go to the PATH that my caffe binary file exist is it caffe.so supposing caffe.so as the required binary file I set the path as below : .. . .. . the result is : .. . .. . Then I want to starts the development server : .. . .. . but finally I face this error : .. . .. . Do you know where I am making mistake", "Question : null .. . Answer : I am using digits for image classification task . I wanted to score the test db and get the predicted prob in csv file . Can anyone tell me where should i make changes in the digits files for that", "Question : Not sure if this is an issue or not - but i have been searching for days and cannot seem to figure it out Any image i try to classify individually using digits seems to run okay . However when using the classify many images button the network crashes because of the aforementioned title bug i dont even know what the hell it is . Im entirely new to caffe and DIGITS and as i said i ve spent days googling this problem - and cant seem to figure it out . what is the 5th dimension on the image and if i do actually have 5D images how do i convert them to 4D Thanks Comment : your question is not clear . can you describe code and or DIGITS screen shots what exactly are you doing that causes the error .. . Answer : Turns out it was a bug - Posted on git and they flagged it officially and patched - to anyone else experiencing this problem update your DIGITS files", "Question : null .. . Answer : I am trying to call the running instance of DIGITS from a front-end Android mobile-application . DIGITS provides a REST API so the curl command would be : .. . .. . It is important to mention that the curl tool is using the Content-Type multipart form-data according to RFC 2388 . This enables uploading of binary files etc . Many people use Android Volley for HTTP POST transfer however for multipart form-data a custom request should be written which turns to be complex . I am looking to send parameter name value to the server where value can be either an image or a String . I have tried so far to adapt the solutions suggested here http : stackoverflow.com questions 32240177 working-post-multipart-request-with-volley-and-without-httpentity and here http : stackoverflow.com a 16803473 3852150 but didn t figure out how to send name value to the server . Adapting these answers or suggesting some more up-to-date libraries would be great . Comment : Did you find solution to your problem Would be interested to learn", "Question : In a recent discussion I found out that some parts of the deploy.prototxt exist only because they have been directly copied from the train test.prototxt and are ignored during testing . For example : .. . .. . I was told that the section containing LR for weights as biases was useless in deploy files and could be deleted . This got me thinking is the convolution param portion absolutely required If yes do we still have to define the weight and bias fillers as we will only do testing using this file and fillers are initialized only when we need to train a network . Is there any other detail that is unnecessary .. . Answer : The convolution param portion is required but you can remove weight filler and bias filler if you want . Comment : Thank you Harsh One small question though : Do I need to remove it or I can if I want to and otherwise it won t be an issue anyway . Comment : @Qazi it s not mandatory to remove these portions . Comment : @Shai Thank you" ] }

Although XML Signature mandates the DSAwithSHA1 signature algorithm it is not required by SAML V2.0 but is RECOMMENDED . While PF is not a code library it s a complete on-premise SSO solution it supports all the various identity protocols needed for cloud computing SAML 1.0 1.1 2.0 WS-Federation and can pretty easily hook into a PHP application via RESTful Web Services or PHP Libraries . Comment : maybe an invalid question but if XML Signature mandates the DSAwithSHA1 signature algorithm how come that the PHP xmlseclibs library that looks like being used widely is not implementing DSA encryption Also is there a free alternative to PF Comment : You d have to ask the guys who wrote the open-source PHP stuff on why they left it out . Probably because it s not required per SAML2 spec . Most commercial SAML solutions should support DSA RSA keys . You might be able to find something free but it will not have the simplicity protocol support or Technical Support options that PF does . Maybe check out PingOne if you just want an external service to call .

It could be that you are hitting this bug https : bugs.php.net bug.php id 61930 but there is no way to know without the error message from PHP .", "Question : We are trying to run simplesamlphp as an SP on RedHat Linux 7 . The code is failing with a HP Fatal error : .. . .. . Call to undefined function mcrypt module open . simplesamlphp uses xmlseclibs 1.3.1 which in turn uses mcrypt and mcrypt is not supported on RedHat Linux 7 . Has anyone found a way to get around this problem Is this a version of xmlseclibs that does not use mcrypt or a version of simplesamlphp that does not use xmlseclibs .. . Answer : You should be able to install the php-mcrypt extension from the Fedora project repo : .. . .. . Check the versions available above is just an example .

I ll give you an example . This is the XML I am trying to sign : .. . .. . I got some code working in PHP to sign it using a combination of public-key and private key certificates and it seemed to work . It added the ds : Signature element with all the proper stuff and it looked great . But then I tested it by immediately trying to validate it after signing it again with xmlseclibs and the public-key certificate but the validation failed . So the exact same code library is doing both the signing and validating but the two processes don t agree for some reason . I added some debugging code to xmlseclibs to find out what it s doing and I realized that the reason the signing key it comes up with and the validation key it comes up with are different are because it canonicalizes things differently in the two situations . When I tell it to sign the samlp : Response element this is the canonical form it signs I ve added newlines here for readability : .. . .. . However when it goes to validate the signature this is the canonical form it computes to validate against again I ve added newlines here : .. . .. . So as you can see this version omits the xmlns : saml attribute from the samlp : Response element while the first does not . Note that this is different from the xmlns : samlp attribute which is included in both . This seems pretty clearly like a bug in xmlseclibs but nonetheless it s one I d be happy to fix myself if I just knew which canonical form was the correct one . Should that attribute be omitted by exclusive canonicalization Or should it be included Which one is the correct exclusive canonical form Comment : It does look like a bug you should post it to xmlseclibs issue tracker . .. . Answer : You are creating the DOM document improperly and trying to use the invalid in-memory tree .

Answer : Neither are the correct canonical-form The signing XML has a namespace declaration that comes after the non-namespace attributes which breaks the Document Order rule : .. . .. . Namespace nodes have a lesser document order position than attribute nodes . The verification XML is missing the saml namespace node completely . Canonicalisation doesn t remove namespace nodes merely because there is no child content that references them . It only removes redundant namespace nodes ie . namespaces that were already in effect on the parent . I don t know enough about xmlseclibs to say why this is happening but it s definitely wrong on both counts . FWIW the c14n function on my DOM here says : .. . .. . eta : I just looked at xmlseclibs.php in the SVN and there s not an easy fix for this as its current approach is fundamentally flawed . It tries to create a canonicalised DOM and then serialises it with plain old saveXML .

Comment : Did you get this working .. . Answer : Speak for yourself . I love phpseclib s build your own example approach to documentation . That said I don t think phpseclib can really be used in this case . So you have the SignatureValue tag .

So far the performance is amazing and I absolutely love being able to use JavaScript for both the front-end and the back-end . I am thinking about using it in some commercial projects but I want to do my due diligence on the viability of such a decision . There are some questions I have and would like some insight into . 1 What enterprise projects if any do you guys know using SilkJS 2 What resources are available regarding the security of using SilkJS as a web-server or other V8 based solutions history of vulnerabilities average time to patch etc . 3 What pitfalls have you guys faced with using SilkJS or other V8 based solutions as a web-server and how if possible have you dealt with it 4 Does SilkJS handle horizontal-scaling well distributing load across multiple servers Is your answer based on theoretical calculations and field-tested examples 5 What resources are you aware of regarding the building of a website using SilkJS as the web-server besides the official website itself Before responding let me first eliminate 80 of the responses I will get with the following constraints : .. . .. . 1 No I will not use NodeJS . For both business and mental-health reasons asynchronous call-back frenzied programming is not something I will use . Do not attempt to convince me that I will get used to it and love it . It s not optimal for the type of projects I am working on . Yes you heard me - asynchronous is not perfect for everything . 2 I am aware that synchronous programming can be simulated in NodeJS . No I am not interested in that either . I am not using NodeJS - get over it . 3 I am fully aware that most applications are i o bound and not cpu bound . As a result yes using PHP is usually fine . However there are certain projects for which cpu optimzations due yield a sizeable return on investment . No a company does not have to be Facebook for this to be true . This is not intended to be a discussion on why PHP is okay . It is an exploration of the reliability of SilkJS for more commercial projects . 3 Yes I know what Java is . No I am not interested on why that would be great if I wanted to reduce the cpu bottleneck . Once again this is not intended to be a discussion on why other languages are okay . It is an exploration of the reliability of SilkJS and V8 based server-side solutions for more enterprise projects . 4 Yes it is possible to have a best answer to this question . Whoever makes the best case for or against the use of SilkJS for use in an enterprise environment gets the correct answer vote . Also I am aware that despite my desire to avoid NodeJS it does utilize V8 . In that regard I am open to security reviews and stability reviews for V8 on the server-side within the context of usage via NodeJS . As for what I mean by enterprise think e-commerce sites with several hundred thousand hits per month and or applications for which stability and up-time are essential and have hundred of thousands of users . My goal here is not to bash SilkJS . I absolutely love it and will continue using it when possible . However as a professional programmer I can t just use what I enjoy for every project . So let the insight commence. . .. . Answer : SilkJS should scale exactly like you would Apache+PHP . Load balancer in front of a farm of SilkJS servers . Scale a MySQL backend like you already know how . SilkJS does not do GZIP or SSL . I think it would be a risk to trust an implementation of either or both of those in the wild against all the various bots hacker or otherwise spiders browser custom perl programs etc . You can trivially implement Apache as a reverse proxy in front of SilkJS to provide those functions . In fact you can shard your server-side application and use apache as a reverse proxy to connect to the proper shard based upon URL requested . I think if you post any security or other issues to the SilkJS google group you will see a patch posted to the github repository in a timely manner . Other than the SilkJS.net site you might look for various repos on github that have example programs using SilkJS . http : www.sencha.com blog discover-music-with-sencha-touch-2 .. . .. .

The data array is the data you re using in the email template while the third parameter is the type of response you expect see pyrocms docs http : docs.pyrocms.com 2.2 manual developers tools events contact-triggers .

Step 1 : Add the Remote Debugging JVM Parameter .. . .. . .. . To use remote debugging you must start CQ5 with this JVM parameter : .. . -agentlib : jdwp transport dt socket address 8000 server y suspend n .. . .. . .. . You can add the parameter by doing the following .. . .. . .. . Start your server like this : crx-quickstart bin start -d --debug-port 8000 . The -d parameter adds the jvm parameter to the CQ5 java process . Add it to your crx-quickstart bin start script CQ JVM OPTS environment variable so your server always starts in debug mode . Include it as a parameter when starting CQ5 with java -jar directly . For example java -Xmx512m .. . .. . .. . -agentlib : jdwp transport dt socket address 8000 server y suspend n -jar cq-author-4502.jar .. . .. . Notes .. . .. . .. . If necessary you can change the port defined under .. . address 8000 .. . from 8000 to something that works better in .. . .. . .. . your environment . Starting CQ 5.5 using the last solution when Quickstart forks a new process it does not start the JVM with the debug options . You can prevent forking by specifying the -nofork command-line option . Te start script is located under crx-quickstart server for CQ versions 5.5 .. . .. . Step 2 : Start a remote debugging session .. . .. . To start a remote debugging session from Eclipse do the following : .. . .. . .. . Open Eclipse . Choose Run Debug Configurations . Right-click Remote Java Applications and select New . Select your CQ5 project under Project . Type in the port from the address configuration of the jvm parameter defined above .

If you really understand Sling and OSGI the JCR stuff is pretty trivial .

I have seen AEM 6.0 the core of it is the same as CQ5 . I checked out the examples all the examples are the same the only difference I found was the UI of WCM i.e . there is a new look-and-feel for it but you can still switch to the classic mode . CQ5 still encourages coding in JSP i.e . it still uses scriplets .

Answer : I would recommend you to take a look for release notes https : docs.adobe.com docs en aem 6-0 release-notes.html .. . .. . I like below features quite a lot : .. . .. . A new repository Apache Jackrabbit Oak . Sightly a new templating language that way you can avoid scriptlet code to a great extent . Supporting better user management by delegating the permissions .

Does anybody know if I can download it to my developer computer I can not find link on web site . I know Adobe offers CRX as opensource - but my interest is in CQ5 cms . .. .

Your reply will really make the difference to my understanding . In other CMS like Vignette content authors create the contents separately not directly on the page for ex . products details and then those contents are iterated processed to display on the page .

Does anybody know if I can download it to my developer computer I can not find link on web site . I know Adobe offers CRX as opensource - but my interest is in CQ5 cms . .. . Answer : According to my rep you need to engage with Adobe to get a copy . We don t have it in house yet as the do want a training session so that users aren t frustrated with the complexity . I ve played around on a test site and also played with it at conventions and it seems like one of the better designed CMS options at the moment .", "Question : According this link http : docs.adobe.com docs en dispatcher.html .. . .. . Dispatcher is Adobe Experience Manager s caching and or load-balancing tool . I need to know what does my dispatcher cache . How can I found out it .. . Answer : The Adobe AEM CQ5 dispatcher simply takes the response body from requests made into the CQ5 instances and saves them as files that then the httpd can deliver . The dispatcher can be configured to allow requests to be either cached or sent directly to the CQ5 instance . This configuration is done in a file dispatcher.any http : docs.adobe.com docs en dispatcher disp-config.html . Check the documentation it is good enough . In general you decide what is cached and what not by defining a set of rules . allow means to cache and deny not to cache . For example : .. . .. . Will : .. . .. . by default cache every request rule 0000 .. . send to the instance requests to that contain en news and private rules 0001 and 0002 . The documentation also describe how to write these rules http : docs.adobe.com docs en dispatcher disp-config.html par title 25 . Finally the dispatcher will never cache requests without extension requests with a query-string non-GET requests and requests with an authentication header .

CQ5 is based on three Apache Software Foundation projects : .. . .. . http : felix.apache.org - the Apache Felix OSGi framework . In general you don t need to know much about it to develop with CQ5 . http : jackrabbit.apache.org - the Apache Jackrabbit JCR content repository the CRX content repository that CQ5 runs on uses the same core code with some extensions . http : sling.apache.org - the Apache Sling web framework which CQ5 uses to process HTTP requests including mapping them to scripts or servlets . Understanding the Sling way of doing things helps a lot in understanding CQ . These 3 projects all have user mailing lists as well .", "Question : The Client Library ClientLib feature in Adobe AEM formerly Adobe CQ makes it easy to include client libraries by category and each library can pull in other libraries through dependencies . However the documentation around Themes is a little thin . This link http : wem.help.adobe.com enterprise en US 10-0 wem developing components.html 3Ccq 3aincludeClientLib 3E is about all I can find on the subject . Here is an excerpt of the sample code : .. . .. . If this tag were to be used how would CQ determine what Client Libs to pull in Does it look for a theme property of type String Or does it look for a certain directory structure in the etc designs section Or does it take the passed in categories and add theme-js to the end like so Or is the theme invoked through the URL In other words the word theme in this case is a token that is replaced with a selector from a URL applied theme .. . Answer : Depends on what you mean by theme . If you are used to wordpress drupal etc what is called a theme in those systems is called a design in CQ5 AEM . To set a design you choose a designpath in the page properties . This will affect where information about components for each template is stored all changes made in design mode about what components are allowed where are stored under this path and is the convention for where CSS JS and non-DAM image resources are stored . It takes planning but you can re-use code and markup in AEM CQ5 but totally change the look by changing the design .", "Question : I m developing a site on Adobe Day CQ . My site should consist of many different components that can not be found in the standard-library Day CQ .

Can any one describe a way how I can create an HTML page from Adobe Illustrator .ai file containing images and font required for web page . I have installed CQ5 instance on my system but don t know how to work with AI files . Thanks in advance . Comment : You need a Web Developer with Adobe CQ knowledge . Can I ask what your skill level is Are you a developer Adobe CQ can be a challenge for the best developers . .. . Answer : Simply put you can t . For starters CQ5 is a modular CMS in that you drag in various components to build a page up . You have page templates that contain the basics of a page such as the header and footer but you don t create entire pages in one go so to speak . You build them up from reusable components . Second you can t automatically convert an illustrator file to a webpage you need a web developer to translate it into HTML Javascript JSP s and CSS . Also CQ5 can require quite a bit of back end coding in Java so that is something to keep in mind . CQ5 is really an enterprise CMS so depending on your needs it might be worth taking a look at something like Wordpress https : wordpress.com although you still wont be able to simply upload an AI file .", "Question : I have a question related with Adobe CQ5 content migration . We have two CQ5 environments.E1 and E2 . We copied content of E1 s author to E2 s author instance . We did it by creating CRX content package . Our content copy went well but now we are realizing that we have missed our versions in pages . For example on E1 we hav a page example.html with three versions 1.0 1.2 1.3 but in E2 we are finding no version of example.html . PS : We create versions manually by Author instance . .. . Answer : The Package Manager only takes the latest version of a page and does not copy it s history .

Is this a one time import or are you rather planning to write a reusable import tool Is the import done by programmers or admins or rather by editors Do you need fault tolerance or a rollback Are you working on productive instances .. .

Upload data in separate file in an own component with a file-upload section 5 parse the data and change the repository . For parsing excel data I would suggest you use apache-poi 6 which is already included in AEM .

How can i use Banana to generate data-visualization of my non indexed database . Comment : I believe currently there is no support for connecting Banana to MySQL . Comment : Thank you for your comment @aadel can you tell me the idea if is there any other solution . Comment : you can either index the data you need to visualize in Solr or use a classical BI tool to do the work in the relational world . Just a note if the fields are stored in Solr but not indexed you can still visualize in Banana but you just won t be able to search them . Comment : Thank you so much I appreciate you .", "Question : How do Elasticsearch and Solr compare in respect to the following : .. . .. . 1 . Indexing logs . 2 . Indexing events . 3 . Indexing PDF documents . 4 . Ease of creating and distributing visualizations . Kibana vs Banana . 5 . Support and documentation for developers . Any help is appreciated . EDIT .. . .. . More specifically i am trying to figure out how exactly a PDF document or an event can be indexed at all . I have worked a little bit on Elasticsearch and since i am a fan of JSON i found it quite useful when i tried to index structured-data . For example logs are mostly structured and thus i guess easier to index and search . Now what if i want to index the whole log file itself Follow up .. . .. . Is Kibana the only visualization tool available for Elasticsearch Is Banana the only visualization tool available for Solr Comment : So this doesn t specifically answer your questions at all since you are concentrating on logging but just something that might be worth a look : stackoverflow.com questions 10213009 solr-vs-elasticsearch http : stackoverflow.com questions 10213009 solr-vs-elasticsearch . I think the post might really boil down to comparison of banana vs kibana not what the title conveys . Another key thing is handling of pdf documents for which you might need to look into plugins at least for Elasticsearch . Comment : downvote should i be more specific Comment : Oh I did not downvote this . I think the question can be updated a bit to focus a bit on your requirements and take out the general elasticsearch vs solr stuff . But to me it seems like good question that I myself am curious about . Considering the stackoverflow post I referenced earlier and how popular that was I don t see why kibana vs banana shouldn t be a good post . Of course your post is more than just that .

I try to stick with minor edits and not speak for the poster . But please review if accepted and change it if you don t like it . .. . Answer : Here is an answer to try to address just the Elasticsearch aspect of the post . Take a look at https : github.com elastic elasticsearch-mapper-attachments for handling PDFs .. . .. . For events logs you would need to transform those into structured-data to index in Elasticsearch . You can have a field in there for the source the log file the data came from and other information like that - you will have all the data in the whole log file indexed in that fashion . You can take advantage of ES aggregations to group results based on log file calculate statistics etc . The ELK stack https : qbox.io blog welcome-to-the-elk-stack-elasticsearch-logstash-kibana is definitely worth a look .

Additionally I want to be able to visualize the data I index into Solr . I m still evaluating on whether to use Banana or Hue for this . Here comes the problem : As far as I understood the Solr docs I can only search on indexed but non-stored fields but not retrieve their original contents . I suppose this will make it quite difficult for the visualizers to produce some nice labeled graphs for me .. . .. . I would really like to avoid storing the fields as the actual data could grow quite big eventually and it is already stored inside another database .

Answer : IMHO the best way to implement such functionality is as a SearchHandler that returns Banana compatible response . You should index the fields that you need to be searchable without storing them in Solr . The search handler should retrieve corresponding rows from HBase according to search results which would enable labeled data in Banana . In a separate process you also have to maintain the index periodically when HBase data are added updated etc .

You could do it and publish the first reactive-banana-gtk project yourself : . .. . Answer : The reactive-banana library can be used on top of any imperative event-based library via the AddHandler type .

In fact the audio didn t start at all . Does this have to do with the fact that the FFI spawns its own thread I m wondering if I need to explicitly fork a thread for SDL . I m really inexperienced with FFI in haskell so I might have the wrong idea . Comment : Do I understand correctly that if you use -threaded then the audio will not start at all but if you don t use -threaded then it will at least start If so then this is an indication that SDL doesn t work well with concurrency . Which is probably unsurprising . Comment : SDL is designed to work with concurrency it has a thread library in it but there are of course some rules .

Type cabal repl and import the file and you should be good to go . Comment : @TingL : No use the cabal file provided in reactive-banana-wx . You can use cabal repl as indicated by Daniel Wagner . Alternatively you could set the buildExamples flag cabal configure -f buildExamples and build the package cabal build which will give you an executable called Animation somewhere in the dist directory . Comment : I see . Thanks . I tried that and encountered a segfault in wxc . stackoverflow.com questions 23367950 wxc-segfault-in-wxhaskell http : stackoverflow.com questions 23367950 wxc-segfault-in-wxhaskell . But it s a different issue . .. . Answer : This question may be outdated by now but I just happened to end up at this page somehow . As of this writing the module appears to be included https : github.com HeinrichApfelmus reactive-banana blob 565d190fddd17a7224dd3609852716b989bfa885 reactive-banana-wx src Paths.hs in the package itself under the src directory . This doesn t appear to be exposed in the cabal file https : github.com HeinrichApfelmus reactive-banana blob 565d190fddd17a7224dd3609852716b989bfa885 reactive-banana-wx reactive-banana-wx.cabal so it s not part of the package s public interface . Instead it is only listed under other-modules for the Animation executable . To answer the question of where to get or how to install this module - just use the cabal file included in the package ." ] }

Note the prefix path usr lib in the usual case rarely some libraries still live under lib for historical reasons On typical 64-bit systems 32-bit libraries live in usr lib and 64-bit libraries live in usr lib64 . Debian Ubuntu organise multi-architecture libraries differently . This should give you a package name e.g . : .. . .. . You can then pkcon install libSM.i686 or specify the version fully : sudo dnf install ibSM-1.2.0-2.fc15.i686 to grab the requisite library . Using pkcon in a GUI or sudo dnf yum apt-get as appropriate .. . .. . Some libraries will have an epoch designator before their name this can be omitted it s an artefact of the way that the underlying RPM libraries handle version numbers e.g . Here the 2 : can be omitted just pkcon install libpng.i686 or sudo dnf install libpng-1.2.46-1.fc16.i686 . It vaguely implies something like : at some point the version number of the libpng package rolled backwards and the epoch had to be incremented to make sure the newer version would be considered newer during updates . Or something similar happened . Twice . Updated to clarify and cover the various package manager options more fully March 2016 Comment : iv installed that now im getting libpam.so.0 : cannot open shared object file Comment : If your app doesn t list its required libraries you ll have to hunt them down and install them yourself if you re lucky they ll be available through yum . You can use ldd binary to list libraries . For each library that is listed that doesn t give a readout like lib ld-linux.so.2 0x4f8d9000 or libc.so.6 lib libc.so.6 0x4f8fa000 try : sudo yum provides lib libWHATEVER.so -- to find the package name s and then sudo yum install PACKAGE.i686 to install it . Making sure to grab the i386 or i686 not x86-64 as it would install by default on your system Comment : This answer is a Godsend when you have 32-bit software that you must migrate to your 64-bit system . Comment : This was very helpful for installing Oracle s jre 1.7 on Fedora 20 . In addition to glibc.i686 I had to install libgcc.i686 . Comment : +1 very helpful Note that for me ldd on the binary in question resulted in not a shared executable . Installing 32-bit glibc was the only way to make forwards progress after installing 32-bit glibc ldd worked and showed dependent libraries .

Answer : Have attempted to test a bunch of custom Salt grains modules utilizing python boto modules for AWS deployments but have continuously run into Python errors .

Generally the modules I ve tested so far run manually fine under 2.7.. . Wanting to know how I can configure a Salt-Master and Minions to default to Python 2.7 . I ve seen this in various peoples salt --versions-report for unrelated issues but I can t figure out how to achieve it myself on CentOS RHEL . Seems even if I have an OS with a base of Python2.7 soon as Salt-Master is installed via yum there comes Python 2.6... . I ve tested on CentOS 6.x Amazon Linux which should be similar which are the main OS es I use . How do I enforce Python 2.7 Is it not possible with CentOS RHEL Amazon would I need another distro Comment : Did you setup the correct repo for your salt . Please cleanup the current salt repo in your OS and refer to this setup repo.saltstack.com rhel http : repo.saltstack.com rhel Comment : Not sure if it was being stuck on Salt 15.5.2 or general install issues with python . It was an older installation from a time when Salt was basically broken on AmazonLinux and I d employed a bunch of workarounds. . Fresh install from latest correct repo did the trick though custom modules no longer crying over python thanks Comment : Perhaps I should push as best practice to saltstack documentation about the repo issues -" ] }

Answer : OLAP standards like XMLA and OLEDB over which the ADOMD.NET library operates do not support real-time updates . Multidimensional continuous queries and associated real-time events are a unique feature of ActivePivot exposed with a proprietary API called the ActivePivot Streaming API . A client with support for real-time OLAP queries should be built against that API this is a large task that goes beyond that a stack-overflow question you should read the documentation of the ActivePivot product and probably liaise with Quartet FS professional services .", "Question : In ActivePivot 5 what number of partitions should I choose for the fact store I have tried different configurations but I m not sure which one to choose . .. . Answer : There isn t a magic number of partitions that works all the time but start with one partition per core in your system . That works well for 80 of the projects . For instance when you deploy your ActivePivot solution on a server with 64 cores configure 64 partitions . The in-memory datastore of ActivePivot is internally split into partitions since version 5.0 . Partitioning provides intrinsic parallelism to most of the data intensive algorithms in ActivePivot . For instance a bulk transaction processing a large-data update into ActivePivot will operate in parallel over the partitions . Similarly a large query aggregating terabytes of data will operate in parallel over the partitions . And for both cases the multi-threading model is very simple : one thread per partition . As each thread runs on its own partition there is very little contention between threads that s one of the main reasons why ActivePivot scales to hundreds of cores . Intuitively knowing that the ActivePivot multi-threading model is to run one thread per partition it makes sense to configure one partition per core so that the largest queries and the largest transactions get the chance to use all the cores in the systems but not more than that . .. . .. . One known exception to this rule of thumb : the projects that focus on smaller datasets with restless real-time updates and calculations . Those projects usually have less than a few tens of gigabytes but process fast paced data updates that continuously trigger the recalculation of hundreds of small continuous queries . Those projects have small datasets and do not benefit much from bulk transactions . More importantly as there may be thousands of concurrent queries there is enough work to keep the cores of the system busy just by running each query single-threaded on one core . For that kind of workload the partitioning becomes more of an overhead than anything and it makes sense configuring only a small number of partitions one two or four for instance.. . .", "Question : Find the CURRENT MEMORY SIZE Does Active Pivot cube expose the current memory size on the cube or Is it possible to find the current Date s memory Size EXample : Total used Size 400Gb CobDate 2014040 Total used Size 200GB .. . Answer : The large-data structures of ActivePivot datastore aggregates primary index and bitmap index are allocated in large continuous chunks they re in general not split by date or any other member and you cannot distinguish . But that being said there are many ways to get the total memory usage or your ActivePivot solution jvisualvm jconsole the Quartet FS health check agent.. . . Then use your favorite frontend to make a simple contributors.COUNT query along your date dimension . That will give you the number of records for each date and the total number of records enough to compute an estimate for the memory usage of each date .", "Question : We are migrating an ActivePivot application to a new server 4 sockets Intel Xeon 512GB of memory . After deploying we launched our application benchmark that s a mix of large OLAP queries concurrent to real-time transactions . The measured performance is almost twice slower than on our previous server that has similar processors but twice less cores and twice less memory . We have investigated the differences between the two servers and it appears the big one has a NUMA architecture non uniform memory acccess . Each CPU socket is physically close to 1 4 of the memory but further away from the rest of it.. . The JVM that runs our application allocates a large global heap there is a random fraction of that heap on each NUMA node . Our analysis is that the memory access pattern is pretty random and CPU cores frequently waste time accessing remote memory . We are looking after more feedback about leveraging ActivePivot on NUMA severs . Can we configure ActivePivot cubes or thread pools change our queries configure the operating-system .. . Answer : Peter described the general JVM options available today to reduce the performance impact of NUMA architectures . To keep it short a NUMA aware JVM will partition the heap with respect to the NUMA nodes and when a thread creates a new object the object is allocated in the NUMA node of the core that runs that thread if the same thread later uses it the object will be in the local memory . Also when compacting the heap the NUMA aware JVM avoids moving large-data chunks between nodes and reduces the length of stop-the-world events . So on any NUMA hardware and for any Java application the -XX : +UseNUMA option should probably be enabled . But for ActivePivot that does not help much : ActivePivot is an in-memory database . There are real-time updates but the bulk of the data resides in the main memory for the life of the application . Whatever the JVM options the data will be split among NUMA nodes and the threads that execute queries will access memory randomly . Knowing that most sections of the ActivePivot query-engine run as fast as memory can be fetched the NUMA impact is particularly visible . So how can you get the most from your ActivePivot solution on a NUMA hardware There is an easy solution when the ActivePivot application only uses a fraction of the resources we find that it is often the case-when several ActivePivot solutions run on the same server . For instance an ActivePivot solution that only uses 16 cores out of 64 and 256GB out of a TeraByte . In that case you can restrict the JVM process itself to a NUMA node . On Linux you prefix the JVM launch with the following option http : linux.die.net man 8 numactl : .. . .. . If the entire server is dedicated to one ActivePivot solution you can leverage the ActivePivot Distributed Architecture to partition the data . If there are 4 NUMA nodes you start 4 JVMs hosting 4 ActivePivot nodes each one bound to its NUMA node . With this deployment queries are distributed among the nodes and each node will perform its share of the work at max performance within the right NUMA node .", "Question : I ve edited to rephrase this question : .. . .. . We want to store trade and sub-trade data . So to give an idea of data we have input data like this : .. . .. . Trade Data Relational Store .. . .. . Sub-Trade Data .. . .. . Any we re looking for the best solution to model this in AP . If we use relational stores to create 2 stores with the same layout as above with the Sub-Trade store being the main ACTIVE PIVOT store and join them based on TradeKey then we end up aggregating incorrectly on the Trade-Level measures as the trade is copied into the cube for each Sub-Trade entry . E.g . TradeLevelMeasure1 has double the correct value as it exists in the cube for both sub-trade entries .. . .. . A solution we ve come up with is to use a single store and add a new dimension to indicate the trade level Trade or SubTrade . So we get something like this : .. . .. . This way we should be able to aggregate correctly and then expand on the sub-trade measures when required . Does this seem like a viable solution or is there a better way to achieve this .. . Answer : Your dataset contains measures that do not have the same dimensionality and thus do not belong to a single cube and its fixed topology . Measures defined at the trade level only aggregate among trades while sub-trade measures only make sense in the context of sub-trades . The ActivePivot Distributed Architecture offers an elegant way to federate heterogeneous cubes on the fly : ActivePivot Polymorphic Distribution . In short you will define two simple cubes one at the trade level with the trade measures and one at the sub-trade level that aggregates only sub-trade measures . ActivePivot Polymorphic Distribution will merge them on the fly into a virtual cube joining on the shared dimensions while also making available the unique measures in each cube .

Answer : ActivePivot implements the standards of OLAP : .. . .. . The MDX query language .. . The XMLA protocol for communications .. . .. . So does Tableau Software . When a multidimensional MDX query is sent to an OLAP provider like ActivePivot a cell set is returned encoded in the XMLA protocol . Most OLAP frontends Microsoft Excel in particular rely on a multidimensional format to represent the cell set in XMLA . But a few rely on the older tabular format that is the case of Tableau Software and also Microsoft SQL Server Reporting Services . ActivePivot supports the XMLA multidimensional format since version 2.0 and the tabular format since version 4.3.3 . ActivePivot 4.3.3 has been tested and works with Tableau Software .", "Question : I have been tasked with coming up with a high performance front-end for a live ActivePivot back-end . I already have a client-side service-layer that provides a continuous stream IObservable T of pre-aggregated pre-formatted data as well as metadata detailing the dimensions and what-not in the report . My requirements can be summarized as : .. . .. . 1 . Dynamically set up row and column headers based on metadata in the stream . 2 . Dynamically pass live data through to the appropriate row column of the control . 3 . Highlight changes to data . eg . increased values may highlight temporarily in green decreased values in red . 4 . Intercept user actions on row column headers ie . drill-downs so that I can instigate a change in the underlying MDX query . 5 . Intercept user actions probably double-click on data values so that I can instigate a drill-through query the results of which would be displayed in a separate data grid . All the third party components appear to be geared around slicing and dicing disconnected or rarely updated data sets . They sacrifice performance to achieve a higher degree of flexibility that I simply don t need and performance is paramount for my scenario . Does anyone know of a WPF control that is performance-focussed and geared more towards the viewing of pre-aggregated pre-formatted data Comment : The words WPF and performance rarely go together if ever .. . good luck . .. . Answer : PivotTable-like frontends that allow slice and dice data exploration are in general associated with OLAP technology . Some of those frontends target one specific server using a proprietary data model and some others implement the standard : MDX queries over XMLA transport . But when OLAP technology was designed 20 years ago doing it in real-time seemed unthinkable . One consequence is that the XMLA standard has no support for updates in a cell set . Actually it practically forbids it because of the static representation of cell sets and cell set axis . ActivePivot can push real-time updates into an OLAP result set and it exposes a proprietary streaming API to subscribe to those updates . The ActivePivot Live frontend was in the first place written to leverage those real-time updates presenting them in familiar pivot-table controls . But in 2013 ActivePivot is still the only OLAP server with real-time support . That explains why there isn t yet a standard to subscribe to OLAP real-time updates . And that also means that as of 2013 and outside of ActivePivot Live you will not find a toolkit WPF or not that has done the whole job of enriching its pivot-table controls with real-time updates . The libraries we know of have actually transposed the static data representation of XMLA in their pivot-table designs making it cumbersome or impossible to update the cells think of the Microsoft Excel Pivot Table for instance . Under the constraint of a particular technology like WPF I would select a general purpose UI toolkit that makes it easy to arrange and compose tables . From there that s a D.I.Y . job . Comment : @KentBoogaart - I ve created a UI toolkit which allows you to create live tables which can be joined filtered extended with calculated-columns and then bound to WPF controls . The tables expose an IObservable interface and have been designed for performance .

To see all the fields when that is needed I added a drill-through details item to the right-click menu that will query the cube for all fields on a single drill-through row and show that in a pop-up . Maybe there is a better way to get this functionality .. . Answer : IQueriesService.retrieveObject is an obsolete service that was introduced in ActivePivot 3.x . At that time ActivePivot stored the input objects directly in the memory and it was natural to provide means to retrieve those objects . But later versions of ActivePivot introduced a column store : the data is extracted from the input objects and packed and compressed into columnar structures . The input objects are then released vastly reducing memory usage . For ActivePivot 4.x the retrieveObject service has been somewhat maintained although indirectly as in fact generic objects are reconstructed on the fly from the compressed data . As you noticed the implementation only supports local cubes . Only MDX queries and Drillthrough queries have a distributed implementation . For ActivePivot 5.x the retrieveObject service has been removed completely in favor of direct access to the underlying datastore . There is a good chance you can address your use-case with a distributed drillthrough query that retrieve raw facts . Another quick fix would be to issue your request manually on each of the local cubes in the cluster . More generally drillthrough queries and also MDX queries and GetAggregates queries are contextual in ActivePivot . You can attach IContextValue s to the query that will alter the way the query is executed . For drillthrough queries in particular you can attach the IDrillThroughProperties context value to the query : .. . .. . This will among other things allow you to retrieve only the columns you want for a specific drillthrough query . Comment : Hi Antoine . Thanks for the answer . I added some context to the question .

Are your measures contained in a separate store linked to the store containing the initial facts Is their any reason why you need to separate the initial facts from your measures Comment : Hi David Both files are being used against a single Relational ActivePivot store . We receive the data spread across multiple-files so load the first file to create the facts and then add the extra measures to the existing facts using the second file . Does that answer your question .. . Answer : If we understand correctly and to simplify the usecase your dataset has two measures A and B . For the same records one file brings measure A and another file brings measure B . And you want to freely update or delete the data for measure A or B independently . There are several ways you can achieve this . First you could decouple the measures : instead of records that bear both A and B fields you would have two records with a generic value field and a mesure type field to distinguish between both measure types . This design is flexible because you can introduce a new measure C later itself fed from another file . The most elegant option is probably to use the ActivePivot Distributed Architecture with Polymorphic Distribution . You would setup two independent cubes one holding only the A measure another cube with the B measure . Then join the cubes together with polymorphic distribution ActivePivot will merge them together on the fly and present both measure as-if they belonged to the same virtual cube . Finally the quick and dirty solution : configure your measures as nullable fields in ActivePivot . This way when you want to erase measure A you actually write null to the A fields of your records . Comment : Thanks Antoine but out problem isn t how to store the empty values but how to detect when the file is deleted . Since the addition of the measures is done inside a Handler when the file is removed it isn t automatically removed when we remove the file . We re extending DefaultTransactionHandler but we don t get any call to the submitStore method on file deletion . Perhaps we re missing something in our configuration . to be clear we do get a call to submitStore when we add a file Comment : You cannot really trigger deletion of data in ActivePivot when you notice that a file has been deleted : at that point the file does not exist anymore and you cannot read it to locate the keys of the records you may want to delete . ActivePivot users generally copy the file into some deleted directory so that it is detected by another file-watcher and pushed by the CSV Source into a special transaction handler that peforms the deletions .", "Question : I would like to retrieve data from activePivot s cube by sending MDX with Rest request . I tried to do it and I retrieved a json object then I parsed this json object to retrieve just specific information look to the picture . I had a look on this question : Can I connect ActivePivot to the tableau software http : stackoverflow.com questions 12473037 can-i-connect-activepivot-to-the-tableau-software but it is not complete . Now I would like to render information whatever the request is in a dynamic table in a web page . How can I do it enter image description here http : i.stack.imgur.com juxtI.png .. . Answer : You are trying to perform what we call the rendering of a Pivot Table from a CellSet . The CellSet and optionally the corresponding Cube discovery information are sufficient to perform this task and you could write it yourself by basically just iterating on the axes and the cells on the CellSet . There is no open-source library that will help you do so to my knowledge the REST Api you are using is recent . Since you are using ActivePivot you might be aware of ActivePivot Live 4 which is the UI front end for ActivePivot which consumes the same API you are consuming and contains a TabularView component that performs what you are trying to do with a lot of added features that could be interesting for you named : .. . .. . Lazy rendering it can render very large CellSets quickly with a low memory-footprint .. . Support for real-time updates on the CellSet via a WebSocket query .. . Highly configurable table you can customize the style of every element programmatically or via a UI .. . Columns can be reordered pinned resized .. . Capability to have a complex rendering of a column or a group of columns sparklines hierarchy trees for instance .. . Components available as a library so you can include them in your Angular application if you prefer .. . .. . This product contains a lot more features that you can for instance see in these two videos everytime you see a table with data this is the TabularView : https : www.youtube.com watch v -B07d4meYbQ and https : www.youtube.com watch v QMTVAtdpuRs . So if you are using ActivePivot Live you can display any MDX as a table in a div with the id table with the following code : .. . .. . Then later you can change the mdx with .. . .. . So that you can wrap this inside an Angular directive for instance . Otherwise you will have to implement it yourself but can of course ask for help here if you have particular issues or bugs you encounter while trying to implement it .", "Question : I would like to know if it is possible to connect activepivot to tableau software By the way is it possible to connect to microsoft reporting-services .. . Answer : Based the information I see here : .. . .. . http : quartetfs.com en products activepivot open-component .. . .. . ...the product understands MDX . It also allows connectivity from Excel which infers that there is an ODBC Other driver that Tableau could also probably leverage .

I could have multiple measures with different formatting but that would complicate a lot of other things . The standard IFormatter framework does not have location information as far as I understand . I guess could implement this as a post processed mesaure I could maybe also have different object types for the different types of prices and then use an IFormatter implementation that switched on the object-type Is there a best practice for this - pros cons .. . Answer : In ActivePivot a formatter does not know the cube location for which a cell has been generated actually with MDX constructs some cell values can be computed that are not associated to any location . But as ActivePivot is object based there is always a solution to do what you want : .. . .. . For the price measure you could write a Price java class that contains an amount and a currency instead of just using a number . Out of the box ActivePivot will not know how to aggregate those prices so you ll also write a custom aggregation function extending com.quartetfs.biz.pivot.aggfun.impl.GenericAggregationFunction . Then you can implement the toString method of your Price class as ActivePivot uses this for default formatting . And you ll have access to the currency when formatting . Of course if you want a more decoupled design or user-based contextual formatting you can also write a PriceFormatter to format your price instances ." ] }

You could read all the documentation and work out which and then add two code paths to handle counters that might be fractional and counters that won t be fractional but this would be a lot of work for very little gain or none . Just use PDH FMT DOUBLE . Update .. . .. . For most counters the precision is only a concern during the calculation of the final value which happens within the PDH library . But as you say the precision of bulk totals such as disk free space could be an issue . Happily it isn t . A double has 52 bits of significand . For a counter reported in bytes this has room for 4 petabytes without any loss of precision . But disk free space is reported in megabytes not bytes so a double can report up to 272 bytes or 4 zettabytes with no loss of precision . And I m pretty sure you can t have a single volume bigger than 264 bytes . Memory use of processes and so is reported in bytes but the values are always multiples of the page-size 4096 bytes so the bottom 12 bits of any reported value are zero . Hence a double can represent a memory size of up to 264 bytes - i.e . the entire 64-bit memory space - without loss of precision . Precision isn t a problem . Just use PDH FMT DOUBLE . Comment : Hi I was thinking a bit about your comment and I think that I might get accuracy problems when using only doubles . On server systems with lots of RAM or with large HDDs this might get a problem .

Basically I am enumerating Process Object instances http : msdn.microsoft.com en-us library aa372151.aspx to get a list of Process objects that I can then query for their process id and compare to my own . Based on this I can build a performance counter path using the correct instance index to create something similar to Process my program 3 counter that I can then use to query whatever counter it is that I am interested in . But what happens if one or more of the other instances of my program exit prior to the PdhAddCounter http : msdn.microsoft.com en-us library aa372204 28v VS.85 29.aspx call If I understand correctly this would mean that my counter path now refers to a different process or is now invalid . They might even disappear while querying for the process id.. . .. . .. . How do I prevent the counter path from becoming invalid before I can use it to get a counter handle Comment : I m pretty sure the path of an existing counter is not going to change . Instances may come and go and end up recycle identifiers and thus paths but as long as your instance lives I m pretty sure it will have the same identifier and thus path . I would be shocked if this were not the case . Comment : @Luke : Unfortunately paths do become invalid . This is easily proven by opening the program in the debugger when another instance has already been started then stepping through to allow the program to determining the correct instance 1 then manually closing the first instance followed by stepping again to allow the program to query the counters - they won t work . .. . Answer : Wow you are right . This seems like a major design flaw to me . Basically it is impossible to reliably monitor an instance if it s name is not unique . I did stumble across a workaround http : msdn.microsoft.com en-us library aa372175 28v VS.85 29.aspx specifically for the Process and Thread objects but that s a global setting that could affect other applications . I think the safest way to do this would be to watch all process objects and each time you collect the data go through and find the one with the desired Process Id . Comment : The workaround might affect other applications so that won t fly as you yourself point out . Would monitoring all processes help at all As far as I can tell there is no way of mapping an open counter to what process it belongs-to . Comment : I don t think you can do this with PdhAddCounter . Maybe you can use the registry interface to collect multiple counters for all processes in that case I believe the counters will be stored sequentially for each object and you can figure it out from there . I may be wrong though I am thinking about this from the perspective of a provider which I recently implemented . Haven t ever written consumer code . Comment : MSDN states : You should not use the registry functions to consume counter data . Comment : That s a recommendation not a mandate . The PDH API is more straightforward to use but the registry API is more capable at the expense of difficulty and tediousness .

The counters aren t entirely accurate so they won t sum to exactly 100 . I don t think you can assemble privileged time from other counters .

Answer : According to this support KB http : support.microsoft.com kb 287159 only the objects and counters have friendly names : .. . .. . However instances do not have a user friendly name in each language . So this leads me to believe that instance names for a given counter are obtained either dynamically e.g .

Of course there is nothing stopping somebody from hard-coding Total in an English build and something else in a German build though it seems the common practice is to keep the language stuff confined to the registry and deal with the objects and counters by index and the instances by dynamic or static names .

In order to get the localized version of Processor Total Processor Time we have to get the localized names of each of the components of the path Processor and Processor Time with the Total being constant . The indexes can vary across OS versions so you have to discover them on each run .

I m developing a standalone sampler synthesizer step sequencer based on a Raspberry Pi 2 think of the good old Electribe SX MX . The GUI is based on SDL2 which I got going after some struggling . The sound engine I chose to use is CSound 6 and it s C++ API . Of course because of the Raspberry Pi being a 32-bit platform I should link against 32-bit libraries . However the CSound manuals give little to no information about the use of the 32-bit libraries other than the few words spent on this http : floss.booktype.pro csound a-the-csound-api page . Of course that would have been enough if libcsound.a or csound.dll or something alike would exist . I ve got everything going with csound64 linked but I m pretty sure that she ll disappoint me when actually compiling for the Raspberry . The bin folder inside my CSound installation folder contains the following files that might have something to do with it but after trying all of them they do not seem to be the library I m looking for : .. . .. .

Pretty sure you don t want to run Windows binaries under an x86 emulator although maybe you could and still manage realtime audio Comment : No I m targeting armhf linux in the end and I might extend this with either a realtime or a preemptive kernel . I also figured that I do not need a specific 32bit library when I finally Cross-compile or compile on the RPi itself . Peter do you think the RPi isn t capable of running a few simple csound synths in parallel Right now I m just wondering where csound would get its routines if installed on a 32bit Windows setup . Just not wondering enough to actually install one and see Comment : I don t know csound . My point was that you can t use Windows DLLs . If you have csound compiled for arm then you re fine . It doesn t matter what you develop with as long as your code is portable between 64 and 32bit Comment : Thanks I figured this . I also think I figured out what I misunderstood : It is not actually the targeted architecture which is 64 or 32-bit but it is the precision of the values that go in and out of csound . There is a symbol one can set by adding a parameter to the linker -DUSE DOUBLE which tells csound to use double-precision values 32-bit instead of 64 bit floating-point values . Comment : Yes 64 vs 32-bit refers to size of pointers integers . Float vs double is a separate thing . .. .

Comment : what do you mean with audio units .. . Answer : Sure it s pretty trivial to do this . Simply link-to the Csound framework in your Xcode project .

I am creating two ftables and loading two different IR s 2048 points long into them at a sample rate of 48kHz . I am using the first gen function table commands iRL ftgen 0 0 2048 -1 IRL.wav 0 0 0 and iRR ftgen 0 0 2048 -1 IRR.wav 0 0 0 . One problem i currently have is setting the function table number to negative -1 does stop scaling but each ftable is scaled differently . One scalemax value is 0.155 and the other 0.145 . I wanted to know how I can completely stop this scaling from occurring so both the IR s are not scaled and loaded into the table . .. . Answer : I think what you do is correct although you do not set the function table number to negative -1 but the GEN number which is 1 for normalising and -1 for simple copy . I cannot believe that any scaling is done by Csound in the case you describe so I see two possibilities for the difference in the scalemax value : .. . 1 The input files have these different maxima . This is very likely if they are real stereo impulse responses . 2 Make sure you really import a mono audio file into the table . If IRL.wav has more than one channel you will get mess . Alternatively you could import both channels into the table using a stereo sound file . Just as a side note I was wondering if you don t need global-variables for the tables giRL and giRR rather than iRL and iRR .

I d like to allow the user to apply pitch-shifting or wah-wah compression on the guitar sound being played . Currently I am using audio samples of the guitar sound . I ve done some basic read-ups on DSP and audio synthesis but I m no expert in it . I saw libraries such as csound and stk and it appears that the sounds they produced are synthesized i.e . not played from audio samples . I am not sure how to apply them or if I can use them to apply effects such as pitch-shifting or wah-wah to audio samples . Can someone point me in the right direction for this .. . Answer : You can use open-source audio processing libraries . Essentially you are getting audio samples in and you need to process them and send them as samples out . The processing can be done by these libraries or you use one of your own . Here s one DSP-Library https : github.com e7mac DSP-Library Disclaimer : I wrote this . Look at the process float float method for any of the classes to see how one does this . Wah-wah and compression are 2 completely different effects . Wah-wah is a lowpass filter whose center frequency varies slowly whereas compression is a method to equalize the volume . The above library has a Compressor https : github.com e7mac DSP-Library blob master Compressor.cpp class that you can check out . The STK does have effects classes as well not just synthesis classes JCRev is one for reverb but I would highly recommend staying away from it as they are really hard to compile and maintain . If you haven t seen this already check out Julius Smith s excellent and comprehensive book Physical Audio Signal Processing https : ccrma.stanford.edu jos pasp Time Varying Delay Effects.html Comment : Thanks e7mac for the reply . Btw do you have references to other dsp library that can do what I mention I m checking out your library out now btw . Thanks . Comment : Try github.com micknoise Maximilian https : github.com micknoise Maximilian or theamazingaudioengine.com http : theamazingaudioengine.com or bartolsthoorn.github.io NVDSP http : bartolsthoorn.github.io NVDSP .

And of course I can hear it this way . But why doesn t direct play work Edited to add : since it seem that the adc s is are causing some kind of problem for PortAudio which don t show up via play through rendered file because presumably it doesn t try to initialize the adcs when playing that way I ve uninstalled ASIO4ALL and rebooted but still no luck playing directly I just get a more cryptic log now because it lists no adcs at all but still doesn t get past enumerating those non-existing adcs now : .. . .. . This with direct run Ctrl+R playing via rendered file Alt+F still works as before . .. . Answer : Meh I fixed it for now by picking no inputs in the config as suggested in http : csound.1045644.n5.nabble.com Csound-QiuteCsound-problem-td3231424.html . This is quite annoying as the line mic input is auto-configured when plugging stuff in on Windows so one would expect PortAudio to manage this much by itself but apparently that s beyond its current feature set .

Answer : As far as I understand it sendmailR doesn t support any type of login to the SMTP server hence gmail is basically unusable . You can only use the package if you are within the right network and set up a server that is only reachable within the network I guess i.e . one NOT using authentication .

Any ideas how to correct this Example email received . https : dl.dropboxusercontent.com u 3734701 Untitled Clipping 032614 022810 PM.jpg .. . Answer : You need to use the Content-Type header to specify the correct MIME type . However apparently the author decided to hardcode this and the headers parameter that the sendmail function provides will not work with Content-Type . You can really hack around it using the trace function which lets you dynamically insert content into other functions .

We are going to replace the function writeLines temporarily within a sendmailR internal function to change text plain non-HTML email to text html . This will force the correct MIME type .

Answer : Outlook is mail client so does sendmailR . I assume you mean you send mail through your SMTP mail-server that your outlook mail client also connect to .

And if you want to use a TCP acknowledgment in step 2 then there s really no other way . Comment : it s my idea to use TCP in step 2 so maybe it s wrong . I think that using udp to acknowledgement exacerbate problems Comment : I think the question has already been answered : pragmatic general multicast https : code.google.com p openpgm . Other than TCP it uses NACK rather than ACK which is more favorable with multicast . How would you handle ACKs for possibly 10 000 clients receiving your datagrams NACKs are sent only when packet-loss is detected in conditions where multicast is available this is usually 1 . .. . Answer : Every client send acknowledgement of receiving that packets using TCP .. . .. . Sending an ACK for each packet and using TCP to do so is not scalable to a large number of receivers . Using a NACK based scheme is more efficient . Each packet sent from the server should have a sequence number associated with it . As clients receive them they keep track of which sequence numbers were missed . If packets are missed a NACK message can then be sent back to the server via UDP . This NACK can be formatted as either a list of sequence numbers or a bitmap of received not received sequence numbers . If server realize that not everyone receive packets it resends multicast or unicast to particular client .. . .. . When the server receives a NACK it should not immediately resend the missing packets but wait for some period of time typically a multiple of the GRTT Group Round Trip Time -- the largest round trip time among the receiver set . That gives it time to accumulate NACKs from other receivers . Then the server can multicast the missing packets so any clients missing them can receive them . If this scheme is being used for file-transfer as opposed to streaming data the server can alternately send the file data in passes . The complete file is sent on the first pass during which any NACKs that are received are accumulated and packets that need to be resent are marked . Then on subsequent passes only retransmissions are sent . This has the advantage that clients with lower loss rates will have the opportunity to finish receiving the file while high loss receivers can continue to receive retransmissions . The problem are that there might be one client who usually lost packets and force server to resend . For very high loss clients the server can set a threshold for the maximum percentage of packets missed . If a client sends back NACKs in excess of that threshold one or more times how many times is up to the server the server can drop that client and either not accept its NACKs or send a message to that client informing it that it was dropped . .. . .. .

Unless multicast routing is enabled on networking devices multicast routers multicast will be available only within one LAN . The only reliable way to go through Internet infrastructure is uni-cast .

I can research but it would not help me until experts give their opinion . .. . Answer : If you can t or don t want to configure routers to forward multicast traffic or otherwise handle a third party protocol you ll need to tunnel multicast traffic over a unicast link . UFTP http : uftp-multicast.sourceforge.net is capable of multicast tunneling via the use of a UFTP proxy server . From the man page : .. . .. . The proxy can run in one of three modes : a server proxy a client proxy or response proxy . .. . A server proxy is typically local to a server and acts as the upstream end of a multicast tunnel . It listens on the public multicast address and private multicast address when specified and forwards downstream packets to a specific address downstream . Upstream packets are forwarded back where the announcement originated from . .. . A client proxy is typically local to one or more clients and forms the downstream end of a multicast tunnel . It receives unicast data from one or more server proxies and forwards downstream traffic to the multicast address specified in the packet header . Upstream traffic from clients is gathered and forwarded back where the announcement came from as an aggregated response . Below is a diagram of a typical configuration where a server sends multicast messages to the local network and one or more server proxies unicast the messages to a corresponding client proxy which in turn multicasts the messages to its local network . These proxies are also capable of working in a NATed environment : .. . .. . If a client proxy is behind a firewall the proxy can send a heartbeat message to the upstream proxy to make a pinhole in the firewall that the upstream server proxy can connect to . If the client proxy is also NATed the upstream server proxy may not know the IP port of the client proxy so the server proxy can be configured to wait for a heartbeat message and use the IP port the heartbeat came from as its downstream address . If the server proxy is also behind a firewall or NAT a second server proxy on a machine with a publicly accessible IP can be inserted between the first server proxy and the client proxy . In this case the first server proxy is set up to use the second as its downstream address and the second server proxy is set up to use the first heartbeat it receives from a client proxy as its downstream address . I m the author of this software so if you need pointers regarding how to set this up send me an email via the link at the bottom of the UFTP page and we ll see what we can do . Update : .. . .. . In the case of PGM it can be configured to run at either the application layer i.e . on top of UDP or at the transport layer i.e . directly on top of IP . If PGM is run at the transport layer that s where you might need to worry about the router having special support for it . Conversely UFTP runs strictly at the application layer .

I am attempting to get a reliable-multicast server client proof of concept setup . The solution itself is a server client connection . The client connects to the server via TCP IP . The server then opens up a reliable-multicast socket for the client to listen on . The client sends messages via TCP and the server echoes it back via IPPROTO RM . The end goal is to have many clients connected to the server all receiving every echoed message . The example code is based off of this page http : www.winsocketdotnetworkprogramming.com winsock2programming winsock2advancedmulticast9d.html . I have set up my RM sockets similarly see listings below . The TCP sockets are working fine . The problem is in the RM sockets . The server opens up the multicast socket then binds and connects to the multicast address properly . The client however listens correctly but the call to accept blocks forever . Both client and server processes are running on the same host . I have checked and Multicasting support is installed on the host Server 2008 . .. . .. . Update : I ve noticed that sometimes the accept will return if I send some data down the socket from the sender s side first . This is not ideal nor is it reliable . Update : The signs are pointing to the switch . Seems like a little hub won t cut it . We had an hilarious incident which resulted in lost comms for the whole building . .. . .. . Listings .. . .. .

Answer : Do you have MSMQ microsoft message queuing installed it is required for IPPROTO RM to work on Ms based computers . Plus it will only work for Windows version Xp 2003 .. . .. . Edit : I saw that you already checked it . Comment : That s right I did indeed check it . MSMQ is installed and so is Multicasting support . all servers are Windows 2008 . Comment : Yea the problem is that the receiver performs accept syncronous and does not return untill the first data was received. . I am currently searching for a workaround to this design perhaps AcceptEx or something . Comment : @RobertH I would seriously take a look at the specs for your switch . Even though I was only sending receiving on the local host it seems like network packets were still being sent to the switch with the multicast flag on . This flooded the whole building about 1000 PCs with multicast packets destined for their origin . Funny but not really what I was after . Comment : @anthony-arnold : There is nothing wrong with the behavior of the switch the expected is behavior . Even though the multicast server and client processes are running on the same host the multicast server data is sent out out the host this is according to the multicast protocol . There could be multicast receivers outside of your subnet building hence the reason for the multicast data to be sent out of the host . And when a switch receives the multicast traffic it will flood it or drop it depending on the configuration . Most of the switches flood . Comment : @MuraliPaluru Yes the point being that the switch needs to be configured in order to handle the PGM traffic without flooding and it wouldn t be unusual for a switch to not be configurable to that level .", "Question : When a sender needs to multicast a relatively large volume of data say several megabytes per second in a reliable way over Ethernet to a modest number of receivers say less than a dozen on the same subnet what is the most efficient protocol By reliable I mean that if a packet is lost the protocol ensures that it gets resent such that there is no data loss in any receiver . The term efficient is a lot harder to define but let s say we want to maximize throughput and minimize network bandwidth with modest CPU usage on both ends .

I d appreciate real-world examples and I ll gladly accept subjective answers i.e . what s your favorite multicast protocol if you can explain its pros and cons . Comment : How many receivers If you have less than ten receivers then you can consider several node-to-node communications . .. . Answer : Real-world example : TIBCO Rendezvous . Data is sent out via multicast with a sequence number . A client that detects a missing sequence number sends out a messge on the multicast group hey I missed packet 12345 . The server re-multicasts out that data . The server has a configurable amount of data to buffer in case a client requests it . The problem : .. . .. . Imagine having a single client that drops half of his packets and 100 healthy clients . This client sends a retransmission request for every other packet . The server begins to cause enough load on one of the healthy clients such that it starts dropping packets and requesting retransmissions . The extra load from that causes another healthy client to begin requesting retransmissions . And so on . A congestion collapse results . Tibco provides a workaround of cutting off a subscriber that sends too many retransmission requests . This makes it harder for a single subscriber to cause a congestion collapse . The other workaround to limit the risk of congestion collapse is to limit the amount of data that a server is willing to retransmit . Tibco should also provide heuristics in the client and server as to whether to multicast or unicast the retransmission request and the retransmission itself . They don t . For the server you could unicast the retransmission if only one client requested it in a certain time window for the client you could unicast the retransmission request if the server has told you - in the retransmitted packet - that you are the only one requesting retransmissions and to please unicast the requests in the future .. . .. . Fundamentally you will have to decide between how strongly you want to guarantee that clients receive data vs the risk of congestion collapse . You will have to make guesses as to where a packet was dropped and whether the retransmission is most efficiently sent unicast or multicast . If the server understands the data and can decide to not send a retransmission if there is updated data to be sent anyway that makes the retransmission irrelevant you are in a much better position than a framework such as Tibco RV . Sometimes understanding the data can lead to wrong assumptions . For example market data - it may seem at first OK to not retransmit a quote when there is an updated quote . But later you may find that a subscriber was keeping a quote history not just trying to keep track of the current quote . Perhaps you may have different requirements depending on the subscriber and some clients will prefer unicast TCP vs multicast . At some point you will need to make arbitrary decisions on the server of how much data to buffer in case of retransmissions or slow clients . Comment : +1 very clear succinct explanation . As I understand Tibco uses PGM protocol and from OpenPGM website it s clear that it provides reliable multicasting . However I m not sure if it can guarantee low-latency as well . Is it possible to have realtime reliable-multicast If not with PGM is there any available technology out there Many thanks . Comment : Yes Tibco provides low-latency . A typical use-case is to broadcast financial values on many screens in a same room the same LAN . Because of the risk of multicast storm as explained above we like to cut the network into segregated multicast zones .

Comment : SCTP and unicast in general is not efficient for what the OP is trying to do : Transferring several megabytes per second to multiple receivers and to maximize throughput and minimize network bandwidth . Bandwidth consumption grows linearly with the number of receivers and a 1GbE link would be saturated at 10MB s with 12 receivers . Using reliable-multicast e.g . PGM the bandwidth under ideal circumstances no packet-loss is completely independent of the number of receivers i.e . a 1GbE link would be less than 10 saturated when doing 10MB s . Comment : Also is SCTP any better for multiple clients than say TCP TCP is heavily optimized even in hardware i.e . NICs . That often means much reduced CPU consumption something the OP is also interested in like Rx Coalescing Checksum offload and so forth . So in general any newcomer will have a hard time beating that .

Answer : Following on from TIBCO the PGM protocol is an open standard reliable-multicast with many optimisations to efficiently work at very large scales with network element acceleration . PGM was developed by TIBCO and CISCO and is an optional protocol underneath TIBCO Rendezvous the default protocol being TRDP which is very similar in design .

This is related to distributed systems . We have basic multicast which just deliver the message with basic guarantees and reliability .

Therefore the term R-multicast reliable-multicast was introduced . The R-multicast brings advance reliability by using the concepts of ATOMIC . It relies on some features such as integrity Validity . Moreover there is an agreement which says each of the members of the group also multicast the message after being delivered . This agreement brings 100 integrity.In addition it can be implemented over either B-multicast or IP multicast such as R-IP multicast vs R-B Multicast .

After all I want to know the differences between IP multicast and B-multicast . .. . Answer : The difference between IP multicast https : en.wikipedia.org wiki IP multicast and basic multicast is related to where-in the network stack the multicast is occurring . In the case of IP multicast this occurs at the network layer i.e . IP . For IPv4 addresses in the range 224.0.0.0 4 224.0.0.0 - 239.255.255.255 are multicast addresses . For IPv6 the addresses are in the FFxx : : 16 range . Packets with destination addresses in this range are sent to multiple hosts as requested via IGMP messages . Basic multicast refers to multicasting at the link layer or below . In the case of Ethernet any frame where the least significant bit of the first byte of the destination address are sent to all nodes in the network . When Ethernet frames carry IPv4 multicast data the destination addresses are in the range 01 : 00 : 5E : 00 : 00 : 00 - 01 : 00 : 5E : 7F : FF : FF while frames with IPv6 multicast data have addresses in the 33 : 33 : xx : xx : xx : xx range . There are other addresses used for other link-layer protocols such as spanning tree or Ethernet flow-control . Some physical layers such as terrestrial wireless or satellite are inherently broadcast . See here more detail on different types of multicast addresses https : en.wikipedia.org wiki Multicast address . As far as reliable-multicast goes that s an application level construct built on top of multicast . Since IP is inherently unreliable reliable-multicast built on top of IP needs to account for this unreliability . Most multicast technologies at lower levels are also unreliable and thus need application layer reliability as well .", "Question : I am preparing for my university exam and one of the question last year was how to make UDP multicast reliable like tcp retransmission of lost packets .. . .. .

How would you handle ACKs for possibly 10 000 clients receiving your datagrams NACKs are sent only when packet-loss is detected in conditions where multicast is available this is usually 1 . .. . Answer : To make UDP reliable you have to handle few things i.e . implement it yourself . Connection handling : Connection between the sending and receiving process can drop . Most reliable implementations usually send keep-Alive messages to maintain the connection between the two ends . Sequencing : Messages need to split into chunks before sending . Acknowledgement : After each message is received an ACK message needs to be send to the sending process . These ACK messasges can also be sent through UDP doesn t have to be through UDP . The receiving process might realise that has lost a message . In this case it will stop delivering the messages from the holdback queue queue of messages that holds the received messages it is like a waiting room for messages and request of a retransmission of the missing message . Flow control : Throttle the sending of data based on the abilities of the receiving process to deliver the data . Usually there is a leader of a group of processes . Each of these groups normally have a leader and a view of the entire group .

You might want to read up on it http : wiki.theory.org BitTorrentSpecification . UDP is useful for multicast but it doesn t provide the guarantees you re looking for - BitTorrent will require you to transmit more than one full copy from the original source but it s still fairly efficient and provides useful guarantees especially considering how much checksumming is done on each chunk of data passed along . Comment : Thanks I had never considered BitTorrent . It s not going to be suitable for my application but it s an interesting idea anyway . Comment : BitTorrent presents a lot of interesting ideas in network-protocols and protocol design . Comment : He specifically asked for an efficient protocol for distributing data on a subnet . While BitTorrent is great for sharing large-files with multiple peers it s not efficient in a LAN setting at all .

Comment : How many receivers If you have less than ten receivers then you can consider several node-to-node communications . .. . Answer : Might I suggest UFTP http : uftp-multicast.sourceforge.net . It uses a NAK based mechanism to determine which packets to retransmit and has an option for either a fixed transmission rate or congestion control using TFMCC http : tools.ietf.org html rfc4654 . Each file is sent in passes where the first pass transmits the entire file while subsequent passes only send retransmissions . Each client keeps track of which packets it received and which ones it missed . At particular checkpoints and at the end of a pass if the receiver missed any packets since the last checkpoint it will send a NAK listing the packets that were missed . This has the advantage that low-loss receivers will finish before high-loss receivers . UFTP can also be configured to drop receivers whose percentage of NAKs exceeds a certain threshold . By limiting NAKs to only receivers that have exhibited loss it reduces the risk of congestion collapse which is the sender getting overwhelmed by receiver feedback .

We have basic multicast which just deliver the message with basic guarantees and reliability . Since the process is alive and doesn t crash the message will be delivered . However if the process crashes there is no guarantee for reliability . Therefore the term R-multicast reliable-multicast was introduced . The R-multicast brings advance reliability by using the concepts of ATOMIC . It relies on some features such as integrity Validity . Moreover there is an agreement which says each of the members of the group also multicast the message after being delivered . This agreement brings 100 integrity.In addition it can be implemented over either B-multicast or IP multicast such as R-IP multicast vs R-B Multicast . In R-B multicast the sender will be imploded by acks when the infra is scalable whereas in R multicast over IP multicast since the omissionn and failure of the message is low due to the IP multicast tech only NACK will be sent back .

The class D : .. . .. . First octet : 224 - 239 .. . First octet pattern : 1110 .. . These IP addresses are multicast addresses . there are used for specific routing protocol service-discovery NTP sometimes experimental use-cases . Network nodes must perform a join multicast-address call in order to receive packet sent to the address multicast-address . There can be many multicast addresses present in a network . Broadcast address .. . .. . There is only one broadcast address in every network . This address is constructed with all its host-part IP address bits set to 1 . If the network is 192.168.0.0 24 the last octet is the host-part IP address and the first three ones are the network-part IP address . The broadcast address is then 192.168.0 . 255 . The broadcast address is used to send packet to all the nodes within the LAN not further not only the nodes that would had performed a join multicast-address call -- that make no sense . .. . .. .

Or do you have an alternative that would not require multicasting I would like to hear about it if so . Comment : There s always the option of setting up a separate TCP connection to each node and sending the data separately on each connection . Whether or not that would be sufficient depends on how many nodes there are likely to be and how much data you need to push . Multicast would still be useful for discovering nodes of course . Comment : @JeremyFriesner that was actually my original plan however that would require a dedicated connection between each node and the data would have to be sent multiple times .

One or more clients start the application but must not be allowed to edit the file at the same time . There are one or more servers of which at least one is always active which one is sort of random .. . The client has a .xml file with all server addresses Comment : If this is meant as a clustered solution in other words : both servers are in the same network consider using a shared filesystem this is by far the easiest solution . Comment : This would certainly be the most comfortable but unfortunately this is not an option for me . Thanks anyway . .. . Answer : A JMS framework ActiveMQ can solve your problem using a queue and a topic : .. . .. . client posts a message on a queue where both server listen asking for the file .. . only one server receives this requests and sends the file to the client .. . client edits the file .. . client sends the edited file on a DURABLE topic where both servers are subscribed .. . .. . Using a durable topic is important so offline subscribers your servers get the file once they reconnect . Comment : Sounds interesting . I will look into this . Where is that durable topic saved Because it mght be a problem if that happens on the Client since I want him to be able to fire-and-forget or simply quit after he sent the file . Comment : Both topic and queue will be managed by the JMS broker e.g . ActiveMQ . This works as a separate application that manages all this communication . Comment : Ok . SO I guess since my client does not stay online the broker has to be on all servers since I can only assume that at least one of them stays active . SO I guess I would create a point-to-point connection from my Client to said server which will in turn act as a broker to notify all other servers of the new file . Does that make sense Comment : The JMS broker will be on one machine only can be one of your servers or a separate machine which is known to stay online . Comment : I think I got that but you see the problem is that at the bare minimum at which it also has to work there will only be the client and the 2 servers . And of these 2 servers I can t safely say which one is reachable . So I guess I have to implement it on both servers as a kind of a fail-safe ." ] }

I m trying to implement Zend Paginator into the quickstart routing mechanism example without success . Let me explain : .. . .. . After following the quickstart I ended with something like this : .. . .. . The problem arises when I tried to implement a paginator for my browse index page . Giving that I need a router like album : action : id : page that doesn t work because the router assigns : page var to : id . I removed the : id section ending with something like album : action : page and invoking in my add edit action .. . .. . working without problems but I like things keep mnemonic . So my question is : Is it possible to achieve this without creating a duplicate router only for the paginator to look like I like an I doing something incorrect Comment : the problem is you are stating id and page are both optional and both will match integers . this means the regular expression will not know which it has matched it s not unique enough .. . Answer : It s not unique enough as an example with a route : .. . .. . id and page are optional and both can be integers .. . .. . if we try to match this route : .. . .. . album index 99 .. . .. . the 99 could match id with page not being present or also page with id not being present . there s no way to know which is which so this will not work . You could add-in an identifier something like this : .. . .. . so then you would have a literal in there to make sure you know it s an id : .. . .. . or album index 99 : page 99 Comment : Excelent .

SQL schema for routes table Comment : Maybe this article can help you : richard.parnaby-king.co.uk 2013 04 http : richard.parnaby-king.co.uk 2013 04 zend-framework-routing-solutions .. . Answer : There are three approaches that I can think of . First is what I ve successfully used in ZF1 . Here s the code https : bitbucket.org mingos ucms src 2f05c7123ac1d84bad8515361183811e69ddbffb application Bootstrap.php at default cl-97 for the routing itself . The idea is simple : set an alias routing which in my case simply used the .html suffix to differentiate it from other URLs . If the routing is found you can get the alias from the DB and then forward the request from the target controller+action to what s defined in the DB like here https : bitbucket.org mingos ucms src 2f05c7123ac1d84bad8515361183811e69ddbffb application modules default controllers IndexController.php at default cl-75 . My code isn t pretty but it works . Second : write your own router . You can extend the router class and simply add yout own route resolving rules there : get data from the DB return true and set params if the alias is in the database . Third : scrape the aliases table and store everything in an .ini file or whatever cache you might be using . This is not much different from what you ve implemented already and all you d need to do would be to automate the alias scraping . Comment : I ended up extending Zend Controler Router Rewrite - And in the route function do a check against the DB if the request is not matched agains at dispatch-able route from the loaded routes.ini . Only other change needed was to tell application in bootstrap to use my custom My Controller Router Rewrite class : - Comment : I believe this is the correct way too : Comment : I have added my solution in the OP", "Question : I am trying to define routes as below with an INI file for the Zend Framework : http : api.example.com servicename version users : userid items : itemid .. . .. . The host-api route works fine but when I try to reach the other routes I get the error No route matched the request .. . .. . The chains.something.chains.somethingelse seems awkward so it probably isn t the correct way to do it . Anyone .. . Answer : I think I have found how to do it . Basically you define the parts of each routes with abstract set to true and link them all with routes whose type is set to Zend Controller Router Route Chain . Something like : Comment : hey i am getting no chain defined error .", "Question : I have managed to make my URL i18n compliant using Zend Controller Router . Ie : en user login becomes fr utilisateur connexion and both URLs go to the same controller action . The problem I am facing is the following .. . .. . I have a language switcher that is displayed as follow : .. . .. . The currently active language doesn t have an anchor tag but all others do . For the languages that have an anchor on them I am building the URL and I want them to be translated in their specific languages . Currently if I am in French all the urls get builded in french even if I set the @local key as a param in the URL view helper tried @locale en @locale new Zend Locale en .. . .. . instead of .. . .. . because the locale used while building the URL is the one that is defined application wide . EDIT .. . .. . I digged a bit deeper in my issue an I found that only the current locale add its resources loaded which mean I can t get route in the proper language for the route to be built-in the right language .. . .. . My new issue is : how do I load multiple language-translation resources I am planning to implement cache in the far future near release so I might get better performances Comment : This is strange . I do the same thing and it works . Do you specifies the route Comment : @Aurelio De Rosa : yes I specify the route to be used . Updated question to specify the issue I m getting now .. . Answer : Hope this helps re the new issue . My new issue is : how do I load multiple language-translation resources .. . .. . Just a quick caveat to say I didn t write the code below it was taken from a example app put together by the guys at Zend however it might help to have it broken down like this . .. . .. . Their approach for the example app was using a csv file containing translations and using your config file the default one in a new project being application.ini to specify the path to all your language-translation resources . like this : .. . .. . And in each csv file if you are using something like Excel or Open Office to create it column A would be the original language and column B the translation . As an example where English is the original language and a Spanish translation is required : .. . .. . You could do that for all the words phrases you want to translate . If a translation isn t found then the default original word is used . Your main application bootstrap could have something like this : .. . .. . As the translate object is held in the session you can use it in any of your views etc using something like : .. . .. . and : .. . .. . where you want something to be translated on selecting an alternative language . In the example above the word login would appear when English is selected and entrar when Spanish is selected . There s loads more to Zend Translate than this and several ways to implement it so I m not saying this is the best way by any means . If it helps or if I can give you more info let me know . Cheers .. . .. . Dave Comment : Hi Jeff hope you re well . Did you get everything working and was this any help to you All the best Dave : -D", "Question : In my IndexController I currently have indexAction homepage loginAction and logoutAction . I m trying to remove index from the URL to get domain.com login instead of domain.com index login . What is the cleanest way to achieve this Is there a RegEx we can use I don t ever want index in the URL . My current solution which I believe can be improved upon is below . Also what does the first parameter in addRoute do .. . Answer : There is nothing to impove you have to create route for every action . This will allow you to change route defaults module controller action without modifying your code . First parameter is the route name which you have to use with url helper in your views : .. . .. . Update . You can use such route if you want only one route without index in url : Comment : I can t use that because I m using Zend Navigation to manage the links . I m looking for a way to use a RegEx so that I only have to use addRoute once . Comment : I updated my answer . BTW what s the problem with Zend Navigation Comment : Thanks That worked except I had to change the 1st param for addRoute from default to index otherwise my URL ended up as domain.com index controller login . There s no problem with Zend Navigation what I meant was I m not building the hyperlinks myself I m simply printing this- navigation - menu from my layout ." ] }

I will mention my thoughts about Gollum since my needs sound similar to your requirements . I have started using Gollum recently for Rails project documentation and my experience so far is very positive . It is developed by the people at Github but it is not tied to the Github service and can be used independently of Github . It is a very active open-source project with many committers . The framework is Sinatra and you can easily run it on your personal workstation . I keep a Gollum server running on my development-machine and edit the Markdown files directly and then view the results in the local Gollum server . This is especially nice if you setup your editor to automatically add your updates with a keystroke .

No dependency is newer than the target so there s nothing to be done . Comment : It isn t an issue . I am just curious . .. . Answer : The chief difference is in whether gmake has a rule to build the target or not . If there is no rule for the target but the target exists then gmake will say Nothing to be done as in I don t know how to update this thing but it already exists so I guess there s nothing to be done .

Can we do that by steps that are similar to conditional-compilation If yes can we please get help with the syntax 3 Our z OS USS Makefiles have shell scripts or groups of commands as in example below with the square brackets presenting the commands to the shell as a group rather than one line at a time .

Check them out bitbucket.org michipili bsdowl https : bitbucket.org michipili bsdowl Comment : @MichaelGr newald thanks . seems the time to migrate to clang.. . .. . Answer : No . The best you can do is use include files with constructed names like : .. . .. . where BUILD TYPE will be debug or whatever . This is certainly not as powerful as-if else but it can do a limited set of things well in a portable manner . In general it s almost impossible to write a portable makefile that uses any feature more sophisticated than the basics provided by POSIX . The makefile syntax is so loose and free-form and yet the features provided by traditional make and the POSIX standard are so anemic that most make vendors have created a large number of non-compatible extensions . Generally when people wonder about this I recommend that they either use automake which takes care of the tedious work of writing portable makefiles for you or else they commit to one make or the other and simply require people to build it if they don t have it .

Answer : If you are using GNU make CURDIR is actually a built-in variable . It is the strike location where the Makefile resides strike the current working directory which is probably where the Makefile is but not always . See Appendix A Quick Reference in http : www.gnu.org software make manual make.html Comment : From the GNU Make manual page 51 : when GNU make starts after it has processed any -C options it sets the variable CURDIR to the pathname of the current working directory . Not the location of where the Makefile is located - although they might be the same . Comment : Downvoted because the answer is not technically correct as noted by Simon Peverett in the previous comment . Comment : @SimonPeverett : The expression in brackets means the the current working directory AFTER -C opts applied . Namely CURDIR gives the exactly the same results for make -C xxx and cd xxx make . Also it removes the trailing . I tried tied with gmake v3.81 .

Can anyone help me I was able to find only one resource http : www.crufty.net help sjg bmake.html that was bit helpful . More help or pointers are appreciated . Thanks Prabhu .. . Answer : BSD make and GNU make are both free replacements for the original AT T make . The major difference is having different syntax for the advanced features . Here is how to put the output of a shell command in a variable in BSD make : .. . .. . And in GNU make : .. . .. . As soon as someone writes shell .. . in a Makefile it requries GNU make . Because of the different syntax some packages require GNU make for the build and some require BSD make . BSD make began its life as PMake short for parallel make . Its author Adam de Boor described PMake in PMake -- A Tutorial http : www.freebsd.org doc en books pmake index.html . Its merit was the new ability to run jobs in parallel as in make -j 3 . This parallel mode broke compatibility by running all commands for each target in a single shell not in one shell per line . GNU make has a parallel mode also -j that keeps one shell per line . NetBSD make 1 http : netbsd.gw.com cgi-bin man-cgi make+1+NetBSD-current now has make -B -j 3 to do parallel mode with one shell per line . OpenBSD make 1 http : www.openbsd.org cgi-bin man.cgi OpenBSD-current man1 make.1 query make sec 1 now always does parallel mode with one shell per line . 4.3BSD-Reno included PMake as make and the bsd . .mk include files . These include files are the best feature of BSD make . src bin sed Makefile in 4.3BSD-Tahoe http : minnie.tuhs.org cgi-bin utree.pl file 4.3BSD-Tahoe usr src bin sed Makefile the release before 4.3BSD-Reno defines several targets like clean depend install and so on . src usr.bin sed Makefile in 4.3BSD-Reno http : minnie.tuhs.org cgi-bin utree.pl file 4.3BSD-Reno src usr.bin sed Makefile has only four non-empty lines : .. . .. . Here bsd.prog.mk automatically sets OBJS to sed0.o sed1.o defines a sed target to link sed from those objects defines other targets like clean depend install and causes make install to install both sed and its manual page sed.1 . There is also bsd.lib.mk for building libraries . When using bsd . .mk each Makefile can build only one program or library . To build another one there must be a second Makefile in another directory . So src usr.sbin smtpd in OpenBSD http : openbsd.cs.toronto.edu cgi-bin cvsweb src usr.sbin smtpd has six subdirectories where each subdirectory only contains a Makefile because smtpd builds six programs . It is also rare to use bsd . .mk to build anything except BSD itself . Many portable packages from BSD developers like OpenSSH from OpenBSD or mksh from MirBSD do not require BSD make and do not use bsd . .mk files . The file bsd.port.mk is at the center of FreeBSD Ports http : www.freebsd.org ports index.html the system that builds software packages for FreeBSD . NetBSD pkgsrc http : www.pkgsrc.org calls this file bsd.pkg.mk . This system has rivals in other scripting languages . Homebrew uses Ruby . MacPorts use Tcl . In the past GNU make was more portable than BSD make . Because BSD make was part of BSD it is rare to find BSD make on other systems . Now there is portable bmake http : crufty.net help sjg bmake.html for other systems . This is a portable version of NetBSD make . The most common use for portable bmake is to run pkgsrc on non-NetBSD systems . I run pkgsrc on OS X with bmake bootstrapped by pkgsrc .

If I write makefiles based on manuals for gnu-make what are the most important portability issues that I need to be aware of Comment : Related : Restricting GNU Make to POSIX Make behaviour @ Unix.SE http : unix.stackexchange.com q 144424 50602 Sadly there seems to be no way of achieving that you can just use .POSIX special target which still leaves many extensions enabled . .. . Answer : GNU Make and POSIX Make share a common core so that GNU Make understands makefiles intended for POSIX Make and interprets them the same way - with very few exceptions . However many GNU Makefiles use features that are only available in GNU Make . Sometimes this is deliberate and conscious sometimes it isn t and sometimes isn t is a problem . I m less familiar with Microsoft nmake I believe it is likely to hew close to the POSIX Make semantics at its core but it will have its own divergent set of extensions . Generally speaking what the programs like autoconf produce are close to portable Makefiles . The main things to be beware of using GNU Make are all the extended function notations for mapping file names macros into useful values . While they are undoubtedly useful they are also a trap for portability . The .x notations for suffix rules are not defined by POSIX http : www.opengroup.org onlinepubs 9699919799 utilities make.html - they are recognized as a common extension : .. . .. . The interpretation of targets containing the characters and is implementation-defined . Comment : I have run into aix make program couple times . Yuck . It is strictly POSIX or is it something else standard-wise Comment : @unknown : it is fairly close to POSIX Make - somewhere between that and one of the System V make programs . POSIX Make is pretty much a common subset of the various make variants . Comment : Also command-line options relevant to MAKEFLAGS variable special targets uppercase starting with dot and built-in rules vary wildly . But e.g . .PHONY special target seems to be supported even outside Gnu Make world . I think the only safe way is to test your makefiles . If you want to play it safe adhere to POSIX even though it defines a very limited make .", "Question : I m expecting to see files foo1 and foo3 created by the makefile below .

Is it advisable to use gnu-make on z OS USS in order to keep our makefiles common 2 If the Makefiles are common then some steps in the Makefiles would still be conditional to the platform . Can we do that by steps that are similar to conditional-compilation If yes can we please get help with the syntax 3 Our z OS USS Makefiles have shell scripts or groups of commands as in example below with the square brackets presenting the commands to the shell as a group rather than one line at a time . It seems that using the GNU make we had to modify these commands to become one line which is messy and the nested loop was a problem . Is there an easier way to group commands using gmake .. .

Yes I d recommend using GNUMake on both platforms and keeping your Makefiles as common as possible . There are a couple of ways to put conditionality in a Makefile .

And there are other more advanced tricks to try when you re bored with these .

By default when make looks for the makefile it tries the following names in order : GNUmakefile makefile and Makefile . Normally you should call your makefile either makefile or Makefile .

The first name checked GNUmakefile is not recommended for most makefiles . You should use this name if you have a makefile that is specific to GNU make and will not be understood by other versions of make .

Has something gone wrong How many packages should there be Comment : @ssorallen Thanks for adding the extra tag I don t have enough rep for that .. . Answer : Nuclide is a single Atom package named nuclide https : atom.io packages nuclide . Install it with apm install nuclide . Prior to Nuclide s Unified Package https : nuclide.io blog 2016 01 13 Nuclide-v0.111.0-The-Unified-Package released on 2016-01-13 Nuclide consisted of 44 separate Atom packages .

Answer : As of 2016 01 13 Nuclide is a single Atom package named nuclide https : atom.io packages nuclide . The nuclide-installer package is no longer needed or supported . Once apm install nuclide completes you are good to go .

I have followed all the installation instructions but autocomplete inline error report click-to-definition features do not work whereas nuclide-language-hack nuclide-file-tree nuclide-remote-projects work as expected and nuclide-server from the server part .hhconfig file is included on project root . I have installed them all except flow by filtering the results of nuclide- . Are these features unsupported in remote-access or i have made something wrong in installation which is pretty straightforward i think Moreover i do not understand how watchman https : facebook.github.io watchman is configured to work properly . I have installed it using the following commands server runs Linux i have also installed inotify-tools .. . .. . and i used the following to watch my project .. . .. . and watcher seems to be established fine . However Nuclide reports : .. . .. . Watcher failed to start - watcher features disabled .. . Details : socket hang up .. . .. . I am sorry that i ask installation advices here but i do not think the above should be asked on Github either . Thanks .. . .. . Solution : As MostafaEweda suggested i tried to compile from source . apm or package installation through atom settings did not work for me . nuclide-installer did not install anything at all and installing by hand nuclide- packages did not work either . For Windows Users : Python3.4 throws some runtime errors although documentation says Python 2.6 or later is supported . I used Python2.7 and these errors seem to go away . Tip : When you install nuclide you have to wait some minutes and atom will become unresponsive . Be patient Comment : If you suspect an issue with watchman it s worth running through facebook.github.io watchman docs troubleshooting.html http : facebook.github.io watchman docs troubleshooting.html . In particular looking at and sharing information from your logs will be helpful to diagnose and suggest a resolution . .. . Answer : It seems that Nuclide s WatchmanClient https : github.com facebook nuclide blob master pkg nuclide watchman-helpers lib WatchmanClient.js can t connect to your installed watchman for some reason . Note that the tests for WatchmanClient is currently disabled but maybe it will show some useful error when you remove the x from line 20 of WatchmanClient-spec.js https : github.com facebook nuclide blob master pkg nuclide watchman-helpers spec WatchmanClient-spec.js L20 and run : npm test in the watchman-helpers directory or add some logging or stack-trace in the command function . However all of these are unrelated to the Hack features not working for you . I recommend trying to build Nuclide from source by : .. . .. . git-clone git@github.com : facebook nuclide.git nuclide cd nuclide . scripts dev setup .. . .. . Then use home USER pkg nuclide server nuclide-start-server as the remote-server command . Finally the contents of log files : nuclide.nohup.out and tmp nuclide-logs nuclide.log on your client and server could help you understand what s going on .

I also have a footer that should be duplicated on each page.I had the idea to use SSI to include the header and footer . As of now we haven t started much server-side processing and thus don t keep track of logged in logged out users . As such for now I just want to use the page that is including the header to determine which to display . I had the idea to use a PHP file as the header instead of an SHTML file so I could do some processing to determine which header to show .

And in header.php I want something like : Comment : if SESSION logged in include logged in header.php else include visitor header.php Comment : this will work even for SSI I was a little worried that being server-side it would obscure the session .

In the end when I m just using the session to determine which header it seems pretty simple but for testing I d like to use the page to determine which header without manually editing each page as I change which pages show what . .. . Answer : So is it possible to determine which page is calling the include with PHP No idea . But if it is possible it will be via SERVER . Put this in your header.php for testing : .. . .. . However if the page is being requested as .html with Server-Side Includes I can t even begin to predict what kind of havoc this is going to play with PHP Sessions . I have doubts that session start will ever be able to set proper headers in this context or if the PHP session cookie will ever be sent to the client or be passed through SSI back to PHP . As far as I am aware concerned SSI should only ever be used to include static content or dynamic-content that does not rely on any sort of interaction with the user including something as basic as-if they re logged in or not . SSI is a kludge between static and dynamic pages and should be referred to as kinda-sorta-dynamic-but-not-really .

However the SSI directives don t get processed before serving the error page . What can I do to fix or work around this", "Question : Can anyone tell me the difference between Server side include and sling dynamic include and their respective use cases .. . Answer : Sling Dynamic Include is actually a way of using Server Side Includes in Apache Sling or CQ5 . Whenever SDI finds an include it will replace it with a SSI tag so the include will be done by the http server and not by the sling engine . There are some nice slides http : www.pro-vision.de content medialib pro-vision production adaptto 2012 adaptto2012-sling-dynamic-include-tomasz-rekaweki-pdf jcr content renditions rendition.file adaptto2012-sling-dynamic-include-tomasz-rekaweki.pdf about that explains how it works . They provide a very nice use-case for SDI when you need to cache almost all a page but you still need to render a particular resource using sling an account menu in a otherwise static page for example . There s also a blog post available http : www.cognifide.com blogs cq sling-dynamic-include with some more commentary than you can find in the slides . One nice thing about them is that it is configured through the OSGi console so you can turn if off developers might not have Apache installed or specify which resourceTypes includes to be turned into SSI", "Question : Cant find any info about it. . so I have few question .. . .. . I need to use it to help solve the big problem of cache invalidation .. . .. . 1 if I understand right it need to search in every file it served to find if it need to include other files sound like very unperfomance 2 does it fetch them one after another or all in the same time 3 does it mean that if I have 3 esi in 1 file than my nginx will recive 3 more request for every request to this file 4 is it in use in 2015 cant find any info about it except the minimal nginx docs which dosent give any technical info thanks Comment : Can you post your ssi configuration in nginx Comment : @Marki555 I dont have yet but is it matter I just want to genral info about how ssi work .. . Answer : Based on the documentation of ngx http ssi module http : nginx.org en docs http ngx http ssi module.html it causes all responses going through to be scanned for SSI commands . So it has nothing to do with files or anything . It doesn t matter from where the content is generated plain file reverse proxy fastcgi php this module will analyze the generated content . 1 . I don t think SSI will bring you major performance penalty unless you are serving and analyzing big binary files . You can limit which content is scanned for SSI by MIME type by default only text html . If you need exact figures you need to do performance tests with and without SSI . 2 . If we are talking about including other files from your SSI commands then by default all of them are fetched in parallel so from time perspective it doesn t matter if you include 1 or 3 files . Of course with 3 files your server has more work to do . 3 . Yes having included more files urls means more requests for nginx unless those urls point to some other server . 4 . The SSI module is still present in latest nginx release but I don t know if any big company actually uses it . It all depends on what you want to achieve . I have still not understood how you want to do cache invalidation with SSI . Comment : Just to add-on point 4 presently SSI is widely used on high-traffic websites . The idea is to get and cache an SSI template from the upstream server first and then fill the dynamic parts of the page with SSI sub-requests which are often handled by memcached or another fast in-memory storage . Every further request will use the already cached SSI template . This approach allows to considerably boost the performance of the website by avoiding requesting the back-end the slowest link in the chain most of the time . Comment : thanks about 4 if i have pages with 10 items on it that I cant know which page have which items . so if 1 item get change I can just purge the ssi which been used in all pages so insted of purging 100 diffrents urls I can just purge 1 file", "Question : What I am trying to do is get Server Side Includes SSI to work on WAMP Server 2.5 downloaded from here http : www.wampserver.com en for Windows 7 .

On a new site I am building on the same server I am getting the error an error occurred when processing this directive when trying to use the tag I have verified that SSI is enabled by using SSI to display the time and date with no problem . I have also verified spelling and that the directory and file are there on the server . Not sure what is wrong can SSI be partly enabled allowing me to display the time with but not allowing include virtual Am I missing something obvious Thanks guys Link to live test . http : christianstest.info TestingServers ComeRestTest index.html .. . .. . Code : .. . Answer : Your SSI tag includes ssi navbar.html . Since that begins with it is parsed as a full path based at the server s document root . http : christianstest.info ssi navbar.html .. . .. . However that s a 404 Not Found . I assume you are trying to include this : .. . .. . http : christianstest.info TestingServers ComeRestTest ssi navbar.html .. . .. . You probably just need to remove the leading in the SSI tag . virtual specifies a URL path relative to the current page but you are pointing it to the root directory of the server . Comment : Yup for some reason removing the leading slash did not fix it but putting in the full file path TestingServers ComeRestTest ssi navbar.html did . Not sure why removing the slash did not work I tried that before as well . I used SSI on another site that was in it s root folder so I got into the habit of putting the leading slash in as this site is on my testing server and in another directory that is what screwed me up .

I ve done this before with ESI and Varnish and expect this to work the same with SSI . Am I wrong in assuming this I can t find an answer online for this and have experimented with different cache-control headers but I m fairly sure this is the right way to do this . What am I missing here .. . Answer : There is a problem in your config : you have SSI enabled in both servers due to .. . .. . defined at http level . This results in SSI directives being expanded in the second server . The response as cached in the first server doesn t have any SSI directives in it there are already expanded and hence it stays the same all the time . If you want included fragment to be fresh on every request you have to enable SSI only in the first server e.g . : .. . .. . Note that ssi on is in the first server along with proxy cache my cache . This way nginx will cache backend responses with SSI directives in them and will redo SSI processing on every request caching includes separately if needed .

More Information on File and Virtual Syntax .. . .. . SSI directives that use file paths can reference files by using a file or virtual path . The file element is used with files that are relative to the folder of the current document . The following example includes a file in the current folder : .. . The virtual element represents paths that are relative to the base folder of the Web server . The following example includes a file in the scripts virtual folder : .. . .. . .. . .. . Conclusion : The file attribute is used to designate a file location that is relative to the current document . So if that is what is needed in your situation you ll indeed need to change the virtual attribute to the file attribute . There is one possible exception though . The article Server Side Includes http : en.wikipedia.org wiki Server Side Includes Most common directives on Wikipedia shows the following example : .. . .. . This suggests to me that a virtual file path does not necessarily need to begin with a . In the absence of a leading the location of a virtual file is relative to the base folder of the web server .

I noticed that there was a braintree gateway in ActiveMerchant and there is also a braintree ruby gem by braintree . Since our system is already designed around active merchant there will be quite a bit of refactoring needed to switch over to the Braintree gem . Is there anything you can t do with the ActiveMerchant Braintree gem that you can in the Braintree gem What advantages does using the Braintree gem have over the ActiveMerchant Braintree gem Thanks in advance .. . Answer : I work at Braintree . You can always get in touch with our support team https : support.braintreepayments.com if you have more questions . The ActiveMerchant gem uses an outdated integration method to integrate with Braintree . It may have different PCI compliance implications than a v.zero integration https : www.braintreepayments.com v.zero as well as lacking new features of the Braintree API . Until ActiveMerchant is upgraded I d suggest using the Braintree gem directly . Comment : Is this still the case Comment : I work at Braintree . The ActiveMerchant gem now supports nonces with Braintree so as long as you pass a payment method nonce instead of a credit-card number when creating a transaction or payment method the PCI compliance implications are the same as a direct Braintree integration using nonces .

Now my issue I want to deduct payment as per user country wise . As per below country and payment . So how can i set currency and payment country wise . Any one have a idea in it Thanks .. . Answer : I am not entirely clear as to what you re seeking but from what I understand you re trying to charge a specified price per sub based on country . From what I have read you shouldn t need to have it determine the country of origin as the gem charges in U.S . currency and the card company should in theory automatically convert it to that price . --Edit-- .. . .. . Okay after I did some digging around it looks as though I was slightly incorrect . If you managed to do what you re trying to do you will get this error response.message : The transaction currency specified must be the same as previously specified . .. . .. . The default currency of the Active Merchant currency is USD . When the transaction goes through it will go through as a USD charge and you can t actually change it when you add the purchase . Therefore you have to change it before it is set to the purchase method . Since you are basing it on a subscription which requires a sign up then you can set the user to have a default country since you have to collect their private information anyway to have a billing address . This way the option is predefined and you just use your currency converter before applying an item to the cart . Comment : Ok Thannks @tommy for response . Can i change default currency of active merchant means for US user USD for India user INR . means Runtime . Comment : Depends on the Gateway you choose to use .

All I need is a very simple way to set up recurring-billing per month by credit-card . I just need a simple solution but am having a hard time finding the best practices of setting it up . So far I understand that this is supported by Paypal s Website Payment Standards option . I just have a few questions regarding how I should implement it : .. . .. . First does Paypal require a user to register for recurring-billing with Website Payment Standard I planned to use ActiveMerchant but I found some blogs that says ActiveMerchant doesn t support recurring-billing from Paypal . is this true I found the SASS Rails Kit by railskits.com which says it supports recurring-billing with Paypal s Website Payments Standard . If I purchased this would the code be clear enough to understand and implement in my own site or is it kind of packaged deal for starter sites and not existing sites I found a lot of blog with help with recurring-billing with ActiveMerchant but using Paypal s Express Checkout . I read about Express Checkout on the Paypal site but I still can t quite understand what it is and how it s different from Website Payment Standard . Can anyone explain this in a simple way If anyone could answer even just one of these questions I d be very grateful By the way before it gets suggested I have watched all of Ryan Bates Paypal screencasts about Paypal which are great for basics or buying items in a shopping cart but I don t understand how it should work with recurring-billing . Also it seemed like he skipped some important steps in the video e.g . the Paypal docs says after your app receives an IPN you need to send back a confirmation of reception to Paypal but Ryan does not do this in his screencast . I m just trying to make sense of all this .. . Answer : First does Paypal require a user to register for recurring-billing with Website Payment Standard .. . .. . With Website Payment Standard you direct your customers to fill out their information on paypal s site . to me that s kind of cheesy but your mileage may vary . If you are going to be making some money it s well worth integrating it into your site and upgrading to Website payments Pro imo . I planned to use ActiveMerchant but I found some blogs that says ActiveMerchant doesn t support recurring-billing from Paypal . is this true .. . .. . It doesn t out of the box but you have to create a new Module class that gets added into Active Merchant plus the views and really it s a lot of work . No should say to you that it s easy to do because they are either liars or really good at programming . I found the SASS Rails Kit by railskits.com which says it supports recurring-billing with Paypal s Website Payments Standard . If I purchased this would the code be clear enough to understand and implement in my own site or is it kind of packaged deal for starter sites and not existing sites .. . .. . Sure it may be clearer but if i recall they use a referential transaction to fake recurring-billing as of this august when i wrote my solution . As for existing sites you may have to gerry rig it into your existing app or create it around it . TBH the 2XX price tag scared me off . I found a lot of blog with help with recurring-billing with ActiveMerchant but using Paypal s Express Checkout . I read about Express Checkout on the Paypal site but I still can t quite understand what it is and how it s different from Website Payment Standard . Can anyone explain this in a simple way .. . .. . Paypal Express requires you to have your own merchant-account . A merchant-account is where your money will end up and is the only for your customer s bank account to speak to your bank account easily . Website Payments Standard uses Paypal s own merchant Account through your Paypal Account in order to pay you . Again imo pay the 30 bucks and go with Website Payments Pro .

Answer : According to the question it doesn t work when the code is by itself but works when require stringio is added . My suspicion is that ActiveMerchant is unit-tested but for some reason the dependency on StringIO isn t detected by those unit tests possibly because other parts of the unit-testing code indirectly require s stringio . One thing I recently found out was that require yaml gives you the stringio library as a side effect : .. . .. . and it wouldn t be hard to imagine unit tests for ActiveMerchant or other parts of Rails requiring yaml .

Comment : This related post might also be helpful for you . stackoverflow.com questions 1683929 http : stackoverflow.com questions 1683929 paypal-recurring-billing-and-activemerchant .. . Answer : Active merchant supports recurring payments for some of its gateways https : github.com Shopify active merchant wiki GatewayFeatureMatrix . Each has slightly different syntax https : github.com Shopify active merchant blob master lib active merchant billing gateways authorize net cim.rb but can accomplish what you want . I would recommend however you pick your payment-gateway and use a specific APi for it . AM lags behind somewhat from my experience and recurring payments are not its primary goal . There are also services out there that will handle all the gateway interaction for you and you just deal with there API . It makes it easier to accept payment and handle Pci DSS requirements in the case of 3rd party hosted payment pages . Comment : I want to use Paypal as a Gateway also I want Paypal to handle the transaction i.e . If user clicks on the subscribe button he is taken to paypal s site and all the transaction is carried out there and if successful an IPN is sent to my site and after the transaction is completed the user comes back to my site I think this is somewhat like Paypal Web Payments Standard .

Staying in the same workflow I d like to either use XFDF or FDF files to add a barcode to the PDF . I m using full-stack JavaScript environment where the Nodejs environment runs server-side . I m using PDFTK Server JavaScript on the server calling out to a PDFTK.exe . I can use any tool technique within my technology stack Nodejs Javascript . Also this solution must work server-side only . The PDF template currently uses a Adobe Lifecycle Paper Forms Barcode control for the barcode . When we fill this PDF form out with data manually the XFA script embedded within the PDF automatically populates the Paper Forms Barcode control with the PDF417 barcode . When I run PDFTK Server s form fill command to populate the PDF with the XFDF data I build-server side I believe the XFA and hence any intelligence behind the Paper Forms Barcode control is automatically removed from the resulting output PDF . I can optionally remove the Paper Forms Barcode control and use any other control available . pdf417-js https : github.com bkuzmic pdf417-js seems to get my close to building a PDF417 barcode but it s client-side . And also I can t see a way to build an image output . From my research it seems I might need to remove the existing Paper Forms Barcode control and add an image somehow to the PDF . Then possibly use PDFTK to somehow merge a PDF that I have filled with data from my existing process with another PDF that simply has the barcode . I never seen an example of XFDF or FDF inserting an image into the PDF . I ve read where one can dynamically add an image icon to a button control via FDF I ve found no hard example of this but haven t been able to get anything working . .. . Answer : FDF does support inserting images as icons into Button fields . I am however not sure whether XFDF does it . You may have to convert the image into PDF format . For an industrial-strength use you might consider dedicated tools such as FDFMerge by Appligent which would also allow to selectively flatten the barcode field and others too . Comment : I tested this with a Acroform PDF . I placed a button on one of the forms we use and set the attribute layout icon only and chose an icon test.jpg from my filesystem . I saved and did an export to both XFDF and FDF . The button was not in the output of either file . Comment : will you kindly remove your answer because I d like to delete my question as I have received multiple negative reviews of it . Comment : The image is not exported you d have to look at the FDF specification which is part of the PDF specification for the complete set of commands . Comment : Don t bother about some downvotes . There are a bunch of ignorant idiots hanging around here downvoting any question concerning PDF Acrobat and JavaScript . I can t name them but I find many such questions downvoted . Otherwise it would be a moderator who could delete the whole question at your request . Comment : @Aaron : this is correct . PDF forms do not know about an image control . There is a possibility to insert images using libraries but in this case the image has to be completely rendered before it can be inserted .", "Question : How to open or view xfdf files in Illustrator . I know it can viewed in PDF but how to view it in Illustrator . Any advice or references is highly appreciated . .. .

Comment : @JLILIAmen I did but it s not something that I would be allowed to do . I have to use the current template . .. . Answer : XFDF is the XML flavor of FDF . FDF stands for Forms Data Format . It is a file-format to store data without the actual content of a PDF . FDF uses PDF syntax to store this data . XFDF uses XML . You can t convert an FDF or XFDF file to PDF because there is too much information missing . You can import an X FDF file into a PDF that has corresponding AcroForm fields . Please take a look at the ImportXFDF http : itextpdf.com sandbox acroforms ImportXFDF example . For that example I wrote a simple XFDF file : data.xfdf http : itextpdf.com sites default files data.xfdf : .. . .. . This information is not sufficient to create a PDF but as you can see there is a reference to a template PDF file : Requisition Fillable.pdf http : itextpdf.com sites default files Requisition Fillable.pdf . If you put data.xfdf and Requisition Fillable.pdf in the same directory and you open data.xfdf you will see the following message : .. . .. . enter image description here http : i.stack.imgur.com z8XJO.png .. . .. . Adobe Reader opened the XFDF file found the reference to the PDF template opened the template and now asks you if you want to import the data . If you click on the Options button and you allow the import you will get this result : .. . .. . enter image description here http : i.stack.imgur.com E3G6d.png .. . .. . The problem you are experiencing is simple : you don t have the file Requisition Fillable.pdf anywhere . You may also want to avoid that people are able to change the data that is filled in . You can solve this by merging the XFDF file and its template programmatically : .. . .. . Mind the following line : .. . .. . This will flatten the form : the fields will no longer be fields they will just be like any other content . You end up with a regular PDF : xfdf merged.pdf http : itextpdf.com sites default files xfdf merged.pdf .. . .. . enter image description here http : i.stack.imgur.com FO9Qf.png .. . .. . Obviously this will only work if the form in this case Requisition Fillable.pdf corresponds with the data in the XFDF stream . For instance : my template will work with your data for the fields Submitted by and Shipping address . It won t work for the fields Job Name and Special Instructions because those fields don t exist in my template . In my template those fields are named Job name and Special instructions do you see the lower cases instead of the upper case If you want to use my template you ll have to change those two field names either in your XFDF file or in the PDF template . Also : my example is written in Java . As you are working in VB you ll have to use the .NET version of iText which is called iTextSharp . An experienced VBA developer shouldn t have any problem porting my example from Java to VB . Just think of the Java as-if it were pseudo-code . DISCLAIMER : the above example requires iText . I am the CEO of the iText Group and the example was taken from my book iText in Action - Second Edition . Comment : wow this is an amazing answer . It does what i m looking for .

Answer : There are commercial applications that do that you can find some at pdfstore.com but with some programming you can create your own using the same library that pdftk is using to process PDF files : iText http : itextpdf.com There is also a .NET version - iTextSharp . By doing that you can access your data from your Java or .NET program and it never needs to exist in file form you could get it out of the database directly . You can also recompile pdftk with a newer version of iText - that way you can the latest PDF processing capabilities and the ease of use that you have with pdftk .

Answer : Your link doesn t really explain what your problem is but I ll take a sample bit of XML from there and walk you through creating it . The principles can be applied to whichever elements you re actually trying to create . So while you can do this with XmlWriter directly this is generally not a good idea - it s very low-level and as a result not very nice to read or write . For example this is the code it would take to just create the outer element and the first child . Notice how you have to be very careful to match writing the start and end of elements : .. . .. .

Answer : Starting with the Add-on SDK 1.4 you have the simple-prefs module https : developer.mozilla.org en-US Add-ons SDK High-Level APIs simple-prefs .

It takes many kilobytes to build a simple extension that includes an XPCOM component What are the advantages and disadvantages of using the Add-on SDK to develop my Firefox extension Is it ready for serious extension development .. . Answer : Advantages : .. . .. . 1 . Jetpack API exposes high level APIs https : addons.mozilla.org en-US developers docs sdk latest modules high-level-modules.html for most of the things you mentioned : .. . .. . Add two context menu items .. . floating panel .. . API for password manager .. . 2 . Jetpack based add-ons are restart-less . 3 . Jetpack based add-ons are future proof in a sense that high level APIs will remain unchanged for the coming versions of FF . 4 . You may be able to use some community developed modules https : github.com mozilla addon-sdk wiki Community-developed-modules for APIs that are not exposed by SDK . 5 . If this is not the last extension you re planning to build there is a potential for code-reuse by building third party modules as ones mentioned in 4 see docs for details .. . .. . 6 . Support for mobile FF is coming in post 1.0 version of Addon-SDK which may mean that your extension can be made compatible with mobile version of FF with minimal to zero effort . 7 . Jetpack comes with build-in unit-testing framework . 8 . Has a better security model which will ease add-on review process . 9 . Jetpack support commonjs modules packages that which means that some of the code can be borrowed from other projects like nodejs for example . Disadvantages : .. . .. . 1 . Jetpack no longer supports FF 4 . 2 . Does not yet have support for localization . 3 . Has no API for building preference panels but can be developed as third party module and shared with rest of the community . 4 . Add-on will contain code with layers of abstractions that will increase size of add-on there is ongoing work that will reduce xpi size by excluding files that are not used by add-on . Comment : +1 gozala . This answer is already almost 2yrs old so there might be more advantages disadvantages now . Comment : The Jetpack libraries are now included in Firefox itself as of version 21 so that will likely result in smaller add-on sizes in the future as support moves to using the built-in libraries .

If anyone knows how to get this working and can point me in the right direction that would be extremely helpful cfx init --template xul doesn t do anything the regular SDK does when I try it Comment : Add-ons should add their icon to the add-on bar that s the official recommendation for all extensions starting with Firefox 4 . If the user wants to clutter his other toolbars he can customize them and drag icons around - that should work for SDK add-ons as well . Comment : As to modifying the add-on manager : you provide absolutely no information as to what you are trying to achieve and asking two questions at once is not a good idea anyway . I suggest that you edit your question to ask about toolbar buttons only and move add-on manager modification into a separate question . Comment : @WladimirPalant thanks for the suggestions . I think many firefox users are still uncomfortable moving icons around . I m afraid people will not like the default position of my add-on menu on the add-on bar and will simply close the bar as a whole rather than going through the trouble of relocating .

So I need to force browser restart on extension update install . I know older version does this by defaultm but these one is restartless So question is : how to force browres restart on extension upgrade I have looked into package.json and found nothing . Comment : Are you looking for a way to mark your extension as non-restartless or programmatically cause a restart from within your code If you are going to do it programmatically without having marked your extension as non-restartless then you should warn the user and ask for confirmation that it is acceptable to the user to restart at this time . Comment : If you are wanting to mark your code as non-restartless you are probably SOL . I would expect any restartless add-on to become non-functional if marked in install.rdf as em : bootstrap false em : bootstrap . A restartless add-on uses a significantly different start-up sequence which I would expect not to be followed if marked as non-bootstrap . In other words I would expect bootstrap.js to not be loaded and nothing in it to be called . Thus I would expect you to need to force the restart yourself . Comment : Have you considered doing proper cleanup instead In my experience it can be a bit tedious to hunt down all the dangling bits but it s generally possible .. . Answer : My expectation is that you are basically SOL if your desire is to try to mark your Add-on SDK extension as non-restartless . The Add-on SDK https : developer.mozilla.org en-US Add-ons SDK produces a restartless https : developer.mozilla.org en-US Add-ons Bootstrapped Extensions extension that uses the standard restartless startup methods . So effectively anytime you create an Add-on SDK add-on you have really created a restartless add-on that is wrapped by the Add-on SDK . You could change in the install.rdf file created when you jpm xpi the following line : .. . em : bootstrap true em : bootstrap .. . to .. . em : bootstrap false em : bootstrap .. . which would cause your extension to be seen as a non-restartless add-on . It would be treated by Firefox and Mozilla Add-ons as an extension which requires a restart to be enabled disabled . However doing so would cause your add-on to not function . The entry points to your add-on would never be called . Thus you must force the restart on your own . You will need to store a preference that indicates that you have or have not restarted i.e . so that you do not end up restarting continuously . See : .. . .. .

The code I use to restart Firefox is : .. . .. . This uses the restart capability that is built into Firefox to perform the restart . Thus there is no need to keep that code updated if there are changes in the exact methodology of how a restart must be performed or any housekeeping associated with doing so . How exactly you would call that function depends on the context you are in when you want to do so . In part this will depend on how you implement informing the user that a restart is required and provide them the option to do so now or later . Given that you have not specified this in the question it is not possible to tell you exactly the code that you need to use in order to cause the restart .

If the icon chosen is changed in the options dialog the icon for any already existent windows will not change . To have those change it is necessary to restart Firefox . The button exists so the user has an easy way to do so . See chrome content options.js and chrome content options.xul . Comment : @msangel I added links to other questions searches and MDN re panels dialogs using Add-on SDK . In addition linked a question on using a preference to perform action only once upon install and the XUL based info on the concept of using a preference to determine if a do once on install action has been performed .", "Question : I know how to show a panel https : developer.mozilla.org en-US Add-ons SDK High-Level APIs panel with position : button .

Answer : The Add-on SDK prevents more than one sdk panel https : developer.mozilla.org en-US Add-ons SDK High-Level APIs panel from being open at a time : .. . You can not do exactly what you are wanting to do . The sdk panel API specifically prevents more than one sdk panel from showing at a time . That is one sdk panel open at a time across all Add-on SDK based extensions loaded in that profile . In other words if some other Add-on SDK based extension opens a panel yours will close . There is no way to disable this using stock Add-on SDK code . This is explicitly stated in the sdk panel documentation https : developer.mozilla.org en-US Add-ons SDK High-Level APIs panel Usage part of the last paragraph in the Usage section : .. . .. . Opening a panel will close an already opened panel . To make it more clear that this restriction is across all Add-on SDK extensions I have updated the text to be : .. . .. . Opening a panel will close any panel created by the Panel constructor that is already open even if that panel was opened by a different Add-on SDK based extension . When you create a panel using the Panel https : dxr.mozilla.org mozilla-central source addon-sdk source lib sdk panel.js 141 constructor a listener is attached to the panel using a call to a private function setupAutoHide this https : dxr.mozilla.org mozilla-central source addon-sdk source lib sdk panel.js 181 . In part the setupAutoHide https : dxr.mozilla.org mozilla-central source addon-sdk source lib sdk panel.js 114 is permanent links for those in this paragraph to the code as it was when this answer was written : Panel https : dxr.mozilla.org mozilla-central rev 23dc78b7b57e9f91798ea44c242a04e112c37db0 addon-sdk source lib sdk panel.js 141 setupAutoHide this https : dxr.mozilla.org mozilla-central rev 23dc78b7b57e9f91798ea44c242a04e112c37db0 addon-sdk source lib sdk panel.js 181 setupAutoHide https : dxr.mozilla.org mozilla-central rev 23dc78b7b57e9f91798ea44c242a04e112c37db0 addon-sdk source lib sdk panel.js 114 . : .. . .. . As you should be able to tell from the comments in this code it is specifically designed to prevent what you desire to do showing more than one sdk panel at a time . Alternate methods to show content : .. . To provide detailed suggestions as to how to accomplish what you desire for your user-interface we are going to need more information as to what you are wanting to do with the two sdk panels https : developer.mozilla.org en-US Add-ons SDK High-Level APIs panel . Given that you have not described the reason you desire to have more than one sdk panel open at one time I have to guess . One reason that you might want to leave an sdk panel open while using another as a drop-down panel to a sdk ui button toggle https : developer.mozilla.org en-US Add-ons SDK Low-Level APIs ui button toggle is that you are using the first one as a semi-permanent display of information or a dialog . In such case you should be using a different UI methodology to display that information . There are multiple possibilities of how to do that depending on what you want your UI to look like . One possibility is to implement a ui frame https : developer.mozilla.org en-US Add-ons SDK Low-Level APIs ui frame . Another possibility is to use openDialog https : developer.mozilla.org en-US Add-ons SDK Low-Level APIs window utils openDialog 28options 29 or open https : developer.mozilla.org en-US Add-ons SDK Low-Level APIs window utils open 28uri options 29 from window utils https : developer.mozilla.org en-US Add-ons SDK Low-Level APIs window utils to open a dialog window . These dialog windows are completely separate windows which can exist as long as you desire . If desired it could be styled to be nearly identical in appearance to an sdk panel . How tightly coupled it is with the current page or window depends on the programming that you do . The Add-on SDK implements sdk panels as XUL popups https : developer.mozilla.org en-US docs Mozilla Tech XUL PopupGuide . There is no restriction within Firefox on displaying more than one XUL popup at a time . You could create these yourself within the primary Firefox DOM rather than using the Panel constructor . Yet other possibilities include : implementing your first sdk panel as a different portion of either the main window UI or as part of the content page alternately the drop-down sdk panel could be implemented as a an actual drop-down menu a menupopup https : developer.mozilla.org en-US docs Mozilla Tech XUL menupopup which can either be an actual menu or have arbitrary content using a panel https : developer.mozilla.org en-US docs Mozilla Tech XUL panel . If you really desired you could code it to display exactly as-if you had used the Panel constructor . However those latter possibilities go around the Add-on SDK and will potentially result in your add-on requiring more on-going maintenance if the underlying structure of Firefox is changed . There are way too many possibilities as to how to implement what you might desire for your UI to cover here . This is particularly the case because we do not know what the goals are of what you are attempting to implement with your UI . Comment : @Haxk20 I have updated this answer to show what Add-on SDK API code specifically prevents what you desire to do . Comment : ok thanks but another question how to show button in panel Comment : @Haxk20 I m not sure what the difficulty is that you are having showing a button https : developer.mozilla.org en-US docs Web HTML Element button in a panel . The button should display just like any other HTML . I m going to need more information as to what the issue is . This would be best handled as separate question . Comment : @Haxk20 I have updated this answer and the documentation on MDN to make it clear that the restriction to one panel is a total of one panel created with the Panel constructor for all Add-on SDK based extensions installed in the profile . If another extension opens a Panel your panel will close .", "Question : I am trying to load a frame script following this tutorial https : developer.mozilla.org en-US Firefox Multiprocess Firefox Message Manager Frame script loading and lifetime : .. . .. . My extension is an Add-on SDK type . The tutorial says I need to specify content in chrome.manifest first . I did not even have that file only package.json and index.js . So I ve created myextension chrome.manifest with a single line : .. . .. . And created a file myextension content content.js : .. . .. . The problem is when mm.loadFrameScript chrome : myextension content content.js true is executed in index.js I get error : .. . .. . I guess it is because the manifest file is wrong or not being registered all together But I couldn t find any clues to my problem on the chrome registration https : developer.mozilla.org en docs Chrome Registration page . .. . Answer : That tutorial is generally targeted towards XUL https : developer.mozilla.org en-US Add-ons Overlay Extensions or restartless bootstrap https : developer.mozilla.org en-US Add-ons Bootstrapped Extensions add-ons . A more appropriate tutorial in that hierarchy is : Multiprocess Firefox and the SDK https : developer.mozilla.org en-US Add-ons SDK Guides Multiprocess Firefox and the SDK . The gist of that page is that if you stay with the Add-on SDK APIs your extension should just work in multiprocess Firefox and that if it doesn t then it is a bug in the Add-on SDK https : developer.mozilla.org en-US Add-ons SDK Guides Multiprocess Firefox and the SDK SDK internal incompatibilities . In general Add-on SDK extensions will use one of the High Level APIs https : developer.mozilla.org en-US Add-ons SDK High-Level APIs to load content scripts https : developer.mozilla.org en-US Add-ons SDK Guides Content Scripts . The primary APIs which would be used are tabs https : developer.mozilla.org en-US Add-ons SDK High-Level APIs tabs and page-mod https : developer.mozilla.org en-US Add-ons SDK High-Level APIs page-mod but there are others e.g . context-menu https : developer.mozilla.org en-US Add-ons SDK High-Level APIs context-menu and page-worker https : developer.mozilla.org en-US Add-ons SDK High-Level APIs page-worker . There are also the Low-Level APIs https : developer.mozilla.org en-US Add-ons SDK Low-Level APIs of remote parent https : developer.mozilla.org en-US Add-ons SDK Low-Level APIs remote parent and remote child https : developer.mozilla.org en-US Add-ons SDK Low-Level APIs remote child which deal with processes https : developer.mozilla.org en-US Add-ons SDK Low-Level APIs remote parent Process and frames https : developer.mozilla.org en-US Add-ons SDK Low-Level APIs remote parent Frame . However you can use frame scripts https : developer.mozilla.org en-US Firefox Multiprocess Firefox Message Manager Frame script loading and lifetime if you desire to do so . Add-on SDK extensions are actually restartless bootstrapped extensions which are wrapped by the add-on SDK . Thus you can do most things which can be done in a bootstrapped extension within an Add-on SDK extension if you really want to do so . However it is better to stay within the APIs provided by the Add-on SDK . If you go around those APIs then you loose some of the advantages which the Add-on SDK exists to provide to you e.g . hiding the actual implementation behind APIs which are intended not to change . Frame scripts and content scripts exist to perform the same function : access the content e.g . HTML pages which has been loaded into an area that is potentially under the control of a different process e10s . Largely the things that are referred to by the two different names are very similar . However you will almost exclusively see the term frame scripts used only for XUL and bootstrap extensions while content scripts will almost always be referring to Add-on SDK scripts . Again you are probably better off using the Add-on SDK APIs to load the scripts you are using to access content that is potentially in another process . Add-on SDK : Using the data directory : .. . .. . For an Add-on SDK extension instead of using a chrome : URL it is more appropriate to use the add-on base directory data directory and obtain the URL reference to your file using the sdk self API https : developer.mozilla.org en-US Add-ons SDK High-Level APIs self . You would do this with : .. . .. . Then your loadFrameScript https : developer.mozilla.org en-US docs Mozilla Tech XPCOM Reference Interface nsIFrameScriptLoader loadFrameScript 28 29 line would be : .. . .. . Using chrome.manifest : .. . .. . content https : developer.mozilla.org en docs Chrome Registration content-instruction lines : .. . The content line of the chrome.manifest file is : .. . .. . This is a minimum of 3 fields separated by whitespace with one or more optional additional fields for flags https : developer.mozilla.org en docs Chrome Registration Manifest Flags . The first field is content which indicates that this is a line that defines how a chrome : packagename content URL will be resolved . The second field is a packagename . This is a name that you make up which must not conflict with other package names already in use by Firefox or those added by other extensions . Usually this will be the name you are using for your add-on or some permutation of the name or id if using multiple content lines . The name and ID of your Add-on SDK are usually the value of the name https : developer.mozilla.org en-US Add-ons SDK Tools package json Key reference and id https : developer.mozilla.org en-US Add-ons SDK Tools package json Key reference properties you included in your package.json https : developer.mozilla.org en-US Add-ons SDK Tools package json file but may be somewhat different https : developer.mozilla.org en-US Add-ons SDK Guides Program ID . The packagename does not need to be your name or ID it just needs to be unique to everything that was loaded into Firefox . The third field is the URL to the directory which contains the files you are going to be referencing . This URL can either be absolute or relative to the location of the chrome.manifest file . This URL must end with a . Firefox looks for the chrome.manifest file in the base directory of your add-on the same one in which package.json is located . While it is possible to have additional chrome.manifest files using the manifest https : developer.mozilla.org en docs Chrome Registration manifest keyword that would be unusual . The prototypical add-on chrome.manifest would contain a line such as : .. . .. . When using the chrome URLs made valid by that content line in your chrome.manifest you would use something like chrome : packagename content myScriptFile.js . This would reference a file called myScriptFile.js that is in the add-on base directory chrome content directory . Another example : .. . chrome.manifest : .. . .. . In this case chrome : myAddOnName content myScriptFile.js would reference the file add-on base directory my special directory myScriptFile.js . Your specific issue : .. . While you stated you were following the tutorial https : developer.mozilla.org en-US Firefox Multiprocess Firefox Message Manager Frame script loading and lifetime you did not actually do so for the contents of your chrome.manifest https : developer.mozilla.org en docs Chrome Registration file . Nor when you changed what that file contained did you follow the description https : developer.mozilla.org en docs Chrome Registration content-instruction of what the content line should contain . However even if you had followed the tutorial exactly you would not have ended up with a functioning add-on because the tutorial was incorrect as to what should be in that file . The line in the tutorial was actually invalid . I have corrected that line in the MDN documentation https : developer.mozilla.org en-US Firefox Multiprocess Firefox Message Manager Frame script loading and lifetime chrome URLs . What you need to use as the line in your chrome.manifest will depend on the directory structure you desire to use for your extension . If you wanted your content.js to exist in a directory add-on base directory chrome content and be referenced by chrome : myAddOnName content content.js then the content line of your chrome.manifest would be : .. . .. . Note : Even though you used myextension in your question in your chrome : URL only for your packagename I have not used it here to try to more clearly indicate that the packagename should be a name you choose which is unique to your add-on . It is not clear to me that you are using myextension in your question as a placeholder for what you are really using within your extension . If that is the actual text you are using rather than a placeholder for your question then I would caution you that the packagename myextension is not very unique and has a reasonable chance to exist in some other random extension . If it does it may or may not cause either or both of your extensions to malfunction . Comment : I appreciate such a detailed answer . You talk about content scripts and frame scripts . You suggest to use content scripts in Addons SDK because it is covered by SDK . Can you tell me if content-script is possibly in my use-case : I need to use nsITextInputProcessor Low level API in that tab .

I would very much like to hear the detailed description of what you tried and how exactly it failed . I can t answer the question in its current form . I don t believe either of these is possible with JetPack . You mean using only the built-in high-level SDK modules . It s possible to write a low-level SDK module that uses XPCOM and interacts with chrome code directly to implement the features you need -- after all that s how the rest of SDK modules are implemented . If you go this route you lose the future compatibility promise of the SDK though -- you ll have to either get it included in the upstream SDK or to update it for the newer Firefox versions yourself .

For Greasemonkey you can see the Greasemonkey Manual http : wiki.greasespot.net Greasemonkey Manual for more information . Which of those you choose would depend significantly on what you are attempting to accomplish and the audience for which you are attempting to make this work among other factors . It would be difficult to write a separate desktop application to modify the HTML code of a site within the Firefox browser and only within Firefox . While this might be possible it would probably be significantly more effort than doing so with a Firefox add-on or using Greasemonkey . Comment : Thats what i really looked for . Btw i meant i want to create a new extension my self to do that job not using grease monkey . Thanks bro" ] }

Now strictly speaking the results you get from this query will be dependent upon the implementation and that s because you described in your question how the nickname field might be null and the JCR 2.0 specification does not specify how the ordering deals with NULL values . For example should they appear before or after non-null values The implementation gets to pick . There s another sticky issue . Notice that I ve assumed that the Person node type has a name field rather than assume that you re storing the name of the person in the node s name . That s because in JCR-SQL2 you have to access the node s name using a special function named NODENAME or NODELOCALNAME . You can use this directly in the ordering but unfortunately obtaining the node s name in the query results is not defined in standard JCR-SQL2 . So the following query using standard JCR-SQL2 would work : .. . .. . but you d have to get the node s name from the javax.jcr.Node obtained from the results rather than one of the values in the result set . Strictly speaking this is neither expensive nor difficult it just changes how your application uses the query results . JCR-SQL2 in ModeShape .. . .. . One JCR implementation ModeShape extends the standard JCR-SQL2 grammar with a number of additional features https : docs.jboss.org author display MODE JCR-SQL2 JCR-SQL2-ExtensionstoJCRSQL2 . One of those extensions is to introduce several pseudo-columns including : .. . .. . jcr : name is a stand-in for the node s name .. . jcr : path is a stand-in for the node s path .. . mode : localName is a stand-in for the local part of the node s name .. . mode : depth evaluates to the depth of the node .. . jcr : uuid evaluates to the result-of javax.jcr.Node.getUUID .. . .. . So you can use the jcr : name pseudo-column both in the ordering and in the SELECT clause : .. . .. . Those options are available in ModeShape 3.x . But the community is currently working on ModeShape 4.0 currently in Alpha and one more extension has been added : you can specify whether nulls should come first or last https : docs.jboss.org author display MODE40 JCR-SQL2 JCR-SQL2-ExtensionstoJCRSQL2 in an ordering . Here s a variation of the earlier query that shows how to use it : .. . .. . If you re Person node type definition ensured that the name property were mandatory never null you wouldn t need to specify the NULLS FIRST or NULLS LAST on the name column ordering . Here s the same query except with jcr : name rather than name : .. . .. . Notice that we didn t need to specify NULLS FIRST or NULLS LAST on the jcr : name column since every node has a name and thus jcr : name will never be null . Standard JCR 1.0 XPath .. . .. . If you re using a JCR implementation that still supports XPath which technically was specified as part of JSR-170 or JCR 1.0 and was deprecated in JSR-283 or JCR 2.0 you can also use XPath : .. . .. . Since JCR 1.0 does define the jcr : name pseudo-column you can actually pretty easily use the node s name : .. . .. . One more thing : ModeShape 3.x or later parses queries written in JCR-SQL2 XPath and JCR-SQL into the same abstract-syntax-tree and then executes them . Therefore the last JCR-SQL2 query and last XPath query would be processed identically in ModeShape . Comment : My case is not select from person order by name nickname .

Answer : Cross-posted from the ModeShape forum https : developer.jboss.org message 918745 918745 : .. . .. . Shared nodes are really just a single node that appears in multiple places within a workspace so it s not exactly clear what it semantically means to get multiple query results for that one shareable node . Per Section 14.16 of the JSR-283 JCR 2.0 specification http : www.day.com specs jcr 2.0 14 Shareable Nodes.html 14.16 20Query implementations are free to include shareable nodes in query results at just one or at multiple all of those locations . ModeShape 2.x and 3.x always returned in query results only a single location of the shared nodes as this was the behavior of the reference implementation and this was the feedback we got from users . When we were working on Modeshape 4.0 we tried to make it possible to return multiple results but we ran into problems with the TCK and uncertainty about what this new expected behavior would be . Therefore we backed off our goals and implemented query to return only one of the shared locations as we did with 2.x and 3.x .

Honestly it ll probably be far easier and far more performant to just use the Node methods to walk up the ancestors .

Alternatively if you just want the paths to the ancestors then you can implicitly get these from the path of a result node e.g . content categories sport nodes .", "Question : I have some records stored as Nodes in JCR and the name of the node is the primary-key . eg 1 2 3 .

But it is comparing the values as string s . For example : .. . .. . Here propertyY is the string in the definition . I tried this with CASE but it still does not work . Can I compare it as double without changing the property definition .. . Answer : Standard JCR-SQL2 has a CAST value AS DOUBLE expression but unfortunately it can only be used on the right-hand side of an expression . Yes JCR-SQL2 is not nearly as flexible as normal SQL . To my knowledge there is not really a valid standard way to convert the property value to a double before running the comparison . If you cast the double value to a string you ll get a lexicographical comparison -- which of course won t really be very useful . I m not sure about other implementations but ModeShape would convert the property value to a double when the property is a residual property since a residual property has no definition and therefore not type .

If you don t include a wildcard like in your pattern there s not much difference between LIKE and the ordinary operator . PATH and NAME are not supported in all implementations of SQL2 .

Thanks Cheers Evan Comment : In my eyes your query is not a valid SQL statement . The computer does need at least the FROM clausel where the computer should finde the nodes . Comment : @reporter You are right it s not a valid SQL statement it was just an example . I changed that to prevent confusion though the problem will remain the same . Comment : I understand you re point and I answered your question below . But your query may be misleading to others : the x in the FROM clause identifies a node type and it s unrelated to the x in the property name s that represents a namespace prefix . Using a different namespace prefix would eliminate this ambiguity : SELECT DATE FORMAT jcr : created Y FROM x Comment : @RandallHauch Thanks for clarifying that . I edited the post .. . Answer : There is nothing in the JSR-283 specification outlining a way to obtain just the year or month or day or time of a DATE field . The only way to accomplish what you want is to get the DATE value using either the rows or the nodes in the javax.jcr.query.QueryResult object as a java.util.Calendar object and .. . .. . If you re query is something like : .. . .. . then the following example shows how to do this by using the rows : .. . .. . It is important to understand that value.getDate will attempt to convert the actual value to a DATE if it is not already one . This may cause an exception if the actual value can t be converted . If the query has a single selector e.g a single table in the FROM clause then each row in the results contains a single node and rather than using the rows as we did above we can get a NodeIterator : .. . .. . Note that we had to use the property name rather than the alias . Comment : I was hoping that there was another way to get the date in the right format directly from the server .

Answer : I don t know of any compressed file-format which would support random-access to a specific location in the uncompressed data well except for multimedia formats but you can brew your own . For example bzip2 compressed files are composed of independent compressed blocks of size 1MB uncompressed which are delimited by sequences of magic bytes so you could parse the bzip2 file get the block boundaries and then just uncompress the right block . This would need some indexing to remember where do the blocks start . Still I think the best solution would be to split your file into chunks of your choice and then compressing it with some archiver like zip or rar which support random-access to individual files in the archive . Comment : I don t need to seek to a specific uncompressed position--only to seek somewhat randomly with some coarse granularity within the compressed file . I don t mind at all if all I can do is say uncompess the data starting here about 700MB into this file . Comment : @John Zwinck : Add your comment to your question as an update . Note that given the variable compression of data some stuff I compress shrinks by 94 or so - usually except when it only shrinks by about 50 or so your estimate of where to start decompressing might be very hit and miss .

Answer : I am the author of an open-source tool for compressing a particular type of biological data . This tool called starch splits the data by chromosome and uses those divisions as indices for fast access to compressed data units within the larger archive . Per-chromosome data are transformed to remove redundancy in genomic coordinates and the transformed data are compressed with either bzip2 or gzip algorithms . The offsets metadata and compressed genomic data are concatenated into one file . Source code is available from our GitHub https : github.com bedops bedops site . We have compiled it under Linux and Mac OS X . For your case you could store 10 MB or whatever offsets in a header to a custom archive format . You parse the header retrieve the offsets and incrementally fseek through the file by current offset sum + header size . Comment : Link is broken . Comment : Updated link-to Github site . Comment : BEDOPS also introduces a novel and lossless-compression format called Starch that reduces whole-genome BED datasets to 5 of their original size and BAM datasets to roughly 35 of their original size -- This is amazing . You should advertise your tool . Comment : We wrote a paper : bioinformatics.oxfordjournals.org content 28 14 1919.abstract http : bioinformatics.oxfordjournals.org content 28 14 1919.abstract Comment : Samtools faidx doesn t compress near as well as Starch and it requires keeping a second file with the genomic data but it offers finer indexing and so is more popular . Starch works really well if you need to squeeze out space or you re doing whole-genome work and want to parallelize tasks by chromosome .

Every .xz file contains an index of the blocks which makes limited random-access reading possible when the block size is small enough . This should be sufficient for your purpose . A drawback is that the API of liblzma for interacting with these containers does not seem that well-documented so it may take some effort figuring out how to randomly access blocks . Comment : Yes that s used for instance by pixz for random-access of members of tar archives or nbdkit for accessing xz compressed files as nbd devices to be able to mount compressed disk images for instance . qcow2 native format for qemu disk images is another format that allows compression and random-access .", "Question : I have a file in a current directory which name is firstName .

Answer : I dont know if its been mentioned yet but the Kiwix project had done great work in this regard . Through their program Kiwix they offer random-access to ZIM file archives . Good compression too . The project originated when there was a demand for offline copies of the Wikipedia which has reached above 100 GB in uncompressed form with all media included . They have successfully taken a 25 GB file a single-file embodiment of the wikipedia without most of the media and compressed it to a measly 8 GB zim file archive . And through the Kiwix program you can call up any page of the Wikipedia with all associated data faster than you can surfing the net . Even though Kiwix program is a technology based around the wikipedia database structure it proves that you can have excellent compression ratios and random-access simultaneously .", "Question : This is similar to a previous question http : stackoverflow.com questions 236414 but the answers there don t satisfy my needs and my question is slightly different : .. . .. .

Answer : I m not sure if this would be practical in your exact situation but couldn t you just gzip each large file into smaller files say 10 MB each You would end up with a bunch of files : file0.gz file1.gz file2.gz etc . Based on a given offset within the original large you could search in the file named file + offset 10485760 + .gz . The offset within the uncompressed archive would be offset 10485760 . Comment : Or you could TAR them all and end up with a .GZ.TAR . : Comment : That would definitely make things cleaner . I was just trying to go for simplicity here but your suggestion is well taken : - Comment : .gz.tar is not really random-access since you must jump through all the headers to get to one file Comment : Well yes and no . With fixed size chunks 10 MB in this case you would not have to walk through a list of headers . This relies on the assumption that the tar will order the files alphabetically which happens to be the case in GNU-land . Comment : Yes but the files would not be compressed then 10 MB uncompressed for your indexing expression to work 10 MB compressed for direct access in tar to work . It s hard to compress anything to a fixed size although you could make that size sufficiently large and handle excess space with sparse files", "Question : This is similar to a previous question http : stackoverflow.com questions 236414 but the answers there don t satisfy my needs and my question is slightly different : .. . .. .

Let the OS deal with compression create and mount a compressed file system SquashFS clicfs cloop cramfs e2compr or whatever containing all your text-files and don t do anything about compression in your application program . 2 . Use clicfs directly on each text file one clicfs per text file instead of compressing a filesystem image . Think of mkclicfs mytextfile mycompressedfile being gzip mytextfile mycompressedfile and clicfs mycompressedfile directory as a way of getting random-access to the data via the file directory mytextfile . Comment : Wow interesting thoughts on an old question of mine . Your first suggestion squashfs is not entirely what I would want because it has implications for remote storage : using a compressed filesystem and compressed SSH connections you would manage to decompress the data and recompress it to send it over the network . What would be amazing would be something like a compressed filesystem that you could share via NFS . Which I guess is what your clicfs suggestion might yield . Documentation on clicfs seems quite hard to come by at least by my quick search but it s promising .

Answer : Because lossless-compression works better on some areas than others if you store compressed data into blocks of convenient length BLOCKSIZE even though each block has exactly the same number of compressed bytes some compressed blocks will expand to a much longer piece of plaintext than others . You might look at Compression : A Key for Next-Generation Text Retrieval Systems by Nivio Ziviani Edleno Silva de Moura Gonzalo Navarro and Ricardo Baeza-Yates in Computer magazine November 2000 http : doi.ieeecomputersociety.org 10.1109 2.881693 .. . .. . Their decompressor takes 1 2 or 3 whole bytes of compressed data and decompresses using a vocabulary list into a whole word . One can directly search the compressed text for words or phrases which turns out to be even faster than searching uncompressed text . Their decompressor lets you point to any word in the text with a normal byte pointer and start decompressing immediately from that point . You can give every word a unique 2 byte code since you probably have less than 65 000 unique words in your text . There are almost 13 000 unique words in the KJV Bible . Even if there are more than 65 000 words it s pretty simple to assign the first 256 two-byte code words to all possible bytes so you can spell out words that aren t in the lexicon of the 65 000 or so most frequent words and phrases . The compression gained by packing frequent words and phrases into two bytes is usually worth the expansion of occasionally spelling out a word using two bytes per letter . There are a variety of ways to pick a lexicon of frequent words and phrases that will give adequate compression . For example you could tweak a LZW compressor to dump phrases it uses more than once to a lexicon file one line per phrase and run it over all your data . Or you could arbitrarily chop up your uncompressed data into 5 byte phrases in a lexicon file one line per phrase . Or you could chop up your uncompressed data into actual English words and put each word -- including the space at the beginning of the word -- into the lexicon file . Then use sort --unique to eliminate duplicate words in that lexicon file . Is picking the perfect optimum lexicon wordlist still considered NP-hard Store the lexicon at the beginning of your huge compressed file pad it out to some convenient BLOCKSIZE and then store the compressed text -- a series of two byte words -- from there to the end of the file . Presumably the searcher will read this lexicon once and keep it in some quick-to-decode format in RAM during decompression to speed up decompressing two byte code to variable-length phrase . My first draft would start with a simple one line per phrase list but you might later switch to storing the lexicon in a more compressed form using some sort of incremental coding or zlib . You can pick any random even byte offset into the compressed text and start decompressing from there . I don t think it s possible to make a finer-grained random-access compressed file-format .", "Question : is there an library or a simple way how to open a password protected ZIP archive in Android I know there are different types of ZIP encryption .

Answer : For the case of .tgz and .tbz most of the performance loss esp for large archives should come from the fact you have to read from disk and uncompressing all data up to and including the file you asked for . If you ask for the last file in the archive then whether a CGI script or a webserver something will still have to spend the time reading uncompressing and discarding all the archive data just to get to your file . Zip format does allow for random-access . If your CGI script is very simple can be a sh script and essentially just calls unzip with the right argument then the amount of speedup you could get from having a server module do it would be rather small .

This is a great idea and it s been around forever except it s been a proposed standard since 1999 . Plus implementations other than IE s are just cumbersome . IE and Opera support it Firefox and Safari with a cumbersome extension . Mozilla has Mozilla Archive Format https : addons.mozilla.org en-US firefox-addon 212 -- basically a ZIP file with the markup and images with metadata saved as RDF . It s an awesome idea -- Winamp does this for skins and ODF and OOXML for their embedded images . I love this except 1 . Nobody else except Mozilla uses it 2 . The only extension supporting it wasn t updated since Firefox 1.5 . Data URIs http : en.wikipedia.org wiki Data URI scheme are becoming more popular . Instead of referencing an external location a la MHTML or MAF you encode the file straight into the HTML markup as base64 . Depending on your view it s streamlined since the files are right where the markup is . However support is still somewhat weak . Firefox Opera and Safari support it without gaffes IE the market leader only started supporting it at IE8 and even then with limits .

This is the summary paraphrasing : .. . .. . FalcorJS and GraphQL are tackling the same problem querying data managing data . The important distinction is that GraphQL is a query language and FalcorJS is not . When you are asking FalcorJS for resources you are very explicitly asking for finite series of values . FalcorJS does support things like ranges e.g . genres 0..10 . But it does not support open-ended queries e.g . genres 0. . . GraphQL is set based : give me all records where true order by this etc . In this sense GraphQL query language is more powerful than FalcorJS . With GraphQL you have a powerful query language but you have to interpret that query language on the server . Jafar argues that in most applications the types of the queries that go from client to server share the same shape . Therefore having a specific and predictable operations like get and set exposes more opportunities to leverage cache . Furthermore a lot of the developers are familiar with mapping the requests using a simple router in REST architecture . The end discussion resolves around whether the power that comes with GraphQL outweighs the complexity .", "Question : null .. . Answer : All : .. . .. . First day on graphQL . After reading a little bit on the GraphQL website conceptually I understand GraphQL itself is like a query language or specification to get customized data-structures but what confuses me is how the GraphQL server is implemented .

Seems should do an array style cache for pagination lookup not sure about this . But graph-api looks a bit different from graphql-relay-js is graph-api still some part of old restful style .. . What is the relationship between graph-api and graphql-relay-js Is graphql-relay-js a common design guide for design a graphql server in facebook Thanks a lot please give me some hints .. . Answer : Connection is a design pattern that your schema may implement if you want Relay to perform efficient pagination . How it gets implemented on the backend is an implementation detail . It may be backed by something array-like or it may not think about something like the infinite scrolling news feed on Facebook which is ranked by a terribly sophisticated backend service : this is clearly not backed by an array . We provide the arrayconnection.js module as a way of demonstrating how this can be done if your data source has that array-like nature . If it does not or cannot be efficiently converted to it you are better off implementing something from scratch . Cursors are opaque identifiers . You could use an array index or some kind of primary-key if you are using an array source or a typical database backend like MySQL but again the details are implementation-specific and should be chosen to suit your back end . The only requirement is that the cursor should encode whatever information you need on the server to be able to return the next page of results after or before that point . graphql-relay-js is just a collection of modules that provide some helpers for building Relay-compatible GraphQL schemas in JavaScript . The schema provides a uniform interface to your data but the actual underlying storage can be anything you want to plug into it a MySQL database an object in memory some REST service . For simple examples look in the examples directory https : github.com facebook-relay tree master examples in the Relay repo . As an illustration of how you can put a schema in front of something that is not a traditional database this https : github.com wincent masochist blob master app src server schema.js is an example of a schema that reads its data out of a Git repo with the help of indices in Redis and cached data in memcached .

Answer : A Relay mutation is defined as an operations that consist of writes to the data store followed by a fetch of any changed fields . . What about something such as logging If I understand your confusion about logging correctly you want to log something in your server but you don t have anything to update on your client-side . You should model this logging operation as a mutation if you want to use GraphQL and Relay for logging . Query is actually a read-only operation .

How should I implement it .. . Answer : Purpose of viewer root query field .. . .. . viewer is not something GraphQL or Relay-specific . Most web-applications serve some purposes of its users or viewers . The top level entity to model the various data served to the user can be named as viewer . You can also name it user . For example the Relay todo example https : github.com facebook-relay blob 5729cc69266d6c18cd8baecd103fdcbda092887d examples todo data schema.js L126 has a viewer root query field : .. . .. .

In short having this viewer as a root query field of the GraphQL schema enables us to provide data based on the current user . Implementation : How to use authentication token together with viewer .. . .. . My answer follows what is already described in your mentioned article . The steps are : .. . .. . 1 . On the server-side create a mutation to obtain an authentication token . Let s name it LoginMutation . Input to this mutation are the user credentials and the output is an authentication token . 2 . On the client-side if you use relay framework https : github.com facebook-relay implement a client-side mutation . After the mutation is successful store the authentication token . 3 . On the client-side Relay code add authToken parameter for your viewer queries . The value of authToken is the authentication token received after successful login mutation . An alternative .. . .. . As already mentioned in the article an alternative way of authenticating user is to do it outside of GraphQL .

What is your scenario that needs string to GraphQL type-conversion Comment : I m interested in building a system that allows for CRUD of types themselves without modification of the code on the server . .. . Answer : The reference GraphQL-JS implementation on GitHub already has a function buildASTSchema that takes a parsed type schema and creates a set of JavaScript objects . So the best way to see how to do it would be to consult that source code on GitHub : https : github.com graphql graphql-js blob master src utilities buildASTSchema.js .. . .. . Alternatively perhaps your tool can be built using that function . Since that repository is maintained by the core GraphQL team you can be pretty confident that it will be up to-date with new additions to the spec . Edit from comment : If what you re trying to do is generate an executable GraphQL schema server from the type language string then you can use the generateSchema function from the graphql-tools package as documented here : http : docs.apollostack.com apollo-server generate-schema.html Comment : That looks like it would be very useful to me If there are no better answers in the next few days this will be the one I accept .

Comment : Added via edit", "Question : How do you prevent a nested attack against an Apollo server with a query such as : .. . .. . In other words how can you limit the number of recursions being submitted in a query This could be a potential server vulnerability . .. . Answer : As of the time of writing there isn t a built-in feature in GraphQL-JS or Apollo Server to handle this concern but it s something that should definitely have a simple solution as GraphQL becomes more popular . This concern can be addressed with several approaches at several levels of the stack and should also always be combined with rate-limiting so that people can t send too many queries to your server this is a potential issue with REST as well . I ll just list all of the different methods I can think of and I ll try to keep this answer up to-date as these solutions are implemented in various GraphQL servers . Some of them are quite simple and some are more complex . 1 . Query validation : In every GraphQL server the first step to running a query is validation - this is where the server tries to determine if there are any serious errors in the query so that we can avoid using actual server resources if we can find that there is some syntax-error or invalid argument up front . GraphQL-JS comes with a selection of default rules https : github.com graphql graphql-js tree master src validation rules that follow a format pretty similar to ESLint . Just like there is a rule to detect infinite cycles in fragments https : github.com graphql graphql-js blob master src validation rules NoFragmentCycles.js one could write a validation rule to detect queries with too much nesting and reject them at the validation stage . 2 . Query timeout : If it s not possible to detect that a query will be too resource-intensive statically perhaps even shallow queries can be very expensive then we can simply add a timeout to the query execution . This has a few benefits : 1 it s a hard limit that s not too hard to reason about and 2 this will also help with situations where one of the backends takes unreasonably long to respond . In many cases a user of your app would prefer a missing field over waiting 10+ seconds to get a response . 3 . Query whitelisting : This is probably the most involved method but you could compile a list of allowed queries ahead of time and check any incoming queries against that list . If your queries are totally static you don t do any dynamic query generation on the client with something like Relay this is the most reliable approach . You could use an automated tool to pull query strings out of your apps when they are deployed so that in development you write whatever queries you want but in production only the ones you want are let through . Another benefit of this approach is that you can skip query validation entirely since you know that all possible queries are valid already . 1 and 2 in particular are probably something every GraphQL server should have by default especially since many new developers might not be aware of these concerns . 3 will only work for certain kinds of apps but might be a good choice when there are very strict performance or security requirements .", "Question : I have an application with users which have many attributes some of which are public and some are private by default and can become public if the user chooses to do so . How can I handle the fetching of private attributes I mean I want that for instance if I ll try to fetch all the user s attributes I ll get all his public attributes and some null-ish value for his private attributes and not unauthorized error message . I also want to somehow override this so the user will have no trouble to fetch all of his data . .. . Answer : As DARK DUCK already stated : You would decide what to return for a certain user in the resolve method of the attributes in your GraphQL server-side schema . I save necessary data for user authentication in a cookie . Then I pass this authentication data down to the GraphQL schema in the root value . In the resolve method of private user data I check the access rights and return the appropriate data null or the actual data . I made a small example repository on how to handle authentication and private data with relay and graphql . See this file https : github.com jkettmann relay-authentication blob master graphql type UserType.js and the posts attribute for a detailed example .", "Question : I m writing client-side code for an app that will query a GraphQL server . In a couple of places in my code I m passing around data that will eventually get turned into a query variable so it needs to validate against a specific GraphQLInputType in my schema . On looking into some of the utilities that graphql-js provides it looks like the isValidJSValue checker is exactly what I m looking for and its comments even mention https : github.com graphql graphql-js blob master src utilities isValidJSValue.js L24 that it s intended to be used to do just that . The issue is that I don t have access to the GraphQL type I want to validate against as a JS object which is what I m pretty sure that function is looking for . I m importing my schema as an npm depdendency as JSON or I also have it in the schema notation . Is there some other utility I can use to get the JS type I need from one of those sources and then use that to check my data with isValidJSValue Or is there some other way I could go about this that I just haven t thought of .. . Answer : You can use the JSON schema you have imported to construct an actual GraphQL schema instance using buildClientSchema here : https : github.com graphql graphql-js blob master src utilities buildClientSchema.js .. . .. . Then it should be a simple matter of looking in the types field of the resulting schema to find your input type and then calling isValidJSValue on it . I m curious though - why validate the value on the client before sending it rather than just relying on the validation the server will do Comment : Thanks that worked I m building something where I need to count on the shape of an object being consistent in a few different places in order to implement undo behavior in my app . One of the places happens to be where I send the mutation to the server and so rather than building some other type checking in I d like to just use what GraphQL gives me out of the box . I think I m going to make it a build-time check or maybe even part of a unit test rather than anything that gets executed at run time - basically just a sanity check for developers .", "Question : Let s say we have the following query taken from the spec : .. . .. .

Answer : Every GraphQL server according to the spec must support a set of queries for introspection : http : graphql.org docs introspection .. . .. . This means you can use GraphQL queries to get information about that server s available types fields queries mutations directives etc . So if you want some specific information you can use that documentation to construct a query that will get it .

Some types need to differ from models for security performance aesthetic design etc .. . Some types span models deliberately .. . Some types encapsulate models for design reasons .. . .. . But they do it everywhere which leads me to think I am missing something important here . .. . Answer : It could simply be that the boilerplate doesn t demonstrate the benefits of this approach . I think you already have some ideas where it could be beneficial for example when your backend data model isn t exactly mapped to your GraphQL API . A lot of organizations adopting GraphQL today have some existing backends and data models that they are used to working with . In this case you can think of GraphQL as just another API layer that sits next to your REST API or anything else . GraphQL is not your actual backend - you shouldn t be handling your business logic directly in the resolvers because then your whole app will become coupled to GraphQL . This isn t as clear when you are building a new app from scratch with GraphQL but it s a good pattern to follow because you will probably want to be flexible with your API in the future . GraphQL is the external interface layer in your app . http : i.stack.imgur.com yDfUP.png .. . .. . In the diagram above GraphQL would be the external interface . Note that it sits on top of the business logic model layer but doesn t replace it . The types in your GraphQL API are the data you want to display in the UI . This could contain computed fields that aren t in the database some fields could be pulling from multiple backends etc .

What is the difference between Falcor and GraphQL in the context of Relay Comment : check out this podcast where Jafar talks about the difference between Relay GraphQL and Falcor JSON Graph youtu.be WL54eYbTJUw t 53m55s https : youtu.be WL54eYbTJUw t 53m55s .. . Answer : I have now written apps with both libraries and I can agree with everything in Gajus post but found some different things most important in my own use of the frameworks . Probably the biggest practical difference is that most of the examples and presumably work done up to this point on GraphQL has been concentrated on integrating GraphQL with Relay - Facebook s system for integrating ReactJS widgets with their data requirements . FalcorJS on the other hand tends to act separately from the widget system which means both that it may be easier to integrate into a non-React Relay client and that it will do less for you automatically in terms of matching widget data dependencies with widgets . The flip side of FalcorJS being flexible in client-side integrations is that it can be very opinionated about how the server needs to act . FalcorJS actually does have a straight up Call this Query over HTTP capability - although Jafar Husain doesn t seem to talk about it very much - and once you include those the way the client libraries react to server information is quite similar except that GraphQL Relay adds a layer of configuration . In FalcorJS if you are returning a value for movie your return-value better say movie whereas in GraphQL you can describe that even though the query returns film you should put that in the client-side datastore as movie . - this is part of the power vs complexity tradeoff that Gajus mentioned . On a practical basis GraphQL and Relay seems to be more developed . Jafar Husain has mentioned that the next version of the Netflix frontend will be running at least in part on FalcorJS whereas the Facebook team has mentioned that they ve been using some version of the GraphQL Relay stack in production for over 3 years . The open-source developer community around GraphQL and Relay seems to be thriving . There are a large number of well-attended supporting projects around GraphQL and Relay whereas I have personally found very few around FalcorJS . Also the base github repository for Relay https : github.com facebook-relay pulse is significantly more active than the github repository for FalcorJS https : github.com netflix falcor pulse . When I first pulled the Facebook repo the examples were broken . I opened a github issue and it was fixed within hours . On the other hand the github issue I opened on FalcorJS has had no official response in two weeks . Comment : GraphQL 2012 has been around long before React and Relay so your first point might not be entirely accurate . Comment : You may be right . I m not a facebooker so I can t really speak to the history . My comment comes more from the current state of facebook s documentation and talks . They were introduced to the world as companions facebook.github.io react blog 2015 02 20 https : facebook.github.io react blog 2015 02 20 introducing-relay-and-graphql.html and both go back quite a ways .

Answer : The solution was not to install pydot from somewhere but python-pydot from official ubuntu repositories . Comment : As of 25-Aug-2013 pip install python-pydot does not work for me distribution not found pip install pydot does . So I don t think it s that pydot is necessarily unofficial . Perhaps you were installing via an OS distribution instead Comment : Not with pip sudo apt-get install python-pydot did it for me . Comment : That would probably work because Ubuntu currently has python-pyparsing at 1.5.2 which avoids the version incompatibility listed above . I went with the fix above and haven t had problems since . Thanks Comment : Unfortunately in Ubuntu as of Saucy pyparsing has been upgraded but pydot has not been patched appropriately .

Comment : I ve never used pydot but I do know Graphviz but a quick look at the pydot docs suggests that you can use a file-like object instead of a file .

But how to replace the write svg function Comment : @PM2Ring As mentioned question isn t limited to pydot itself . Can you tell me a way to get the svg string corresponding to dot string in Graphviz . Any way is fine . Comment : If .write svg accepts an open file handle instead of a file name then it will just work if you supply it a StringIO or BytesIO object .

I hope my requirement is clear . If you need more details please let me know . Here is my code : .. . .. . Thanks in advance.. . .. . Answer : A few things here . 1 . Kendo relies on JQuery but you re trying to initialize the progress widget before the JQuery handler initializes . Always place Kendo code inside the JQuery handler and be sure to include the reference to JQuery library before your Kendo scripts . 2 . Make sure your put code to turn off the progress-bar in every possible code path or it will run indefinitely and your users won t be able to proceed . In your example you have kendo.ui.progress progressBar false in the Complete handler for the second call but not the first . If the user were to get an error on the first call the progress-bar would never be turned off . 3 . You re disabling async mode here in code but your comment makes me think you don t mean to . async : false isn t necessary here since you are making the 2nd AJAX call in the success of the first . In doing it this way you control the execution order of the calls yourself . 4 . I think you know this already but setting a pre-defined timeout value on any kind of progress indicator isn t a good idea because you have no way of knowing just how long that process will take .

Answer : Using requestStart sync requestEnd to show and hide a spinner is not wise .

My issue seems to be from the view that is referred in the subquery - currentGoldMarkings . While execution MySQL first materializes this subquery and then implements the where clauses of queryCode and runId which therefore results in execution-time of more than hour as the view refers tables that has got millions of rows of data . My question is how do I enforce those two where conditions on the subquery before it materializes . Here are the two views . Both of these also get used in a standalone mode and so integrating any clauses into them is not possible . Note : The above query reflects only a part of my actual query . There are 3 other left outer joins which are similar in nature to the above subquery which makes the problem far more worse .

I have verified that that portion of the article is identical to the 5.7 doc and I have updated the link accordingly Comment : @Strawberry : that s been true for a long time I can t say it s for all versions . Back in MySQL 3.23 we couldn t even use a subquery . This well documented behavior and well tested performance differences is why some of us continually and strongly advocate alternatives to the ubiquitous IN NOT IN subquery form . It s never a problem for small sets where we never notice the performance difference . It s when we scale up to a real volume of data that the performance difference is significant .", "Question : I don t understand the behaviour in this case .

If you are asking how to change this behavior .. . it seems that you can t . Comment : Yep . It this use proper but longer code and everything s fine thing .. . Answer : The reason is because when an unaliased column doesn t exist in the subquery but does exist in the outer query Oracle assumes you are referring to the column from the outer query . With aliases the query you re confused about would look like : .. . .. . Hopefully that makes things clearer The issue you re seeing is a very good example of why you should always label your columns with which table they came from - it makes it much easier to maintain the query for a start Comment : Thank you . Indeed I m still astonished that it works like this . Thinking not of a select but a somehow stored delete statement you might get to inadvertently delete lines from table A by altering the columns of table B and not even touching the statement itself urghs . Ok going to use aliases now whenever using more than one table Comment : @evilive it works like that because of correlated subqueries - e.g . select from table1 t1 where exists select null from table2 t2 where t1.col1 t2.col1 . I.e . the scope of the outer query extends to the top level of any subquery within it . So if the query is explicit about which columns it s using Oracle has to guess which table the column comes from . And props for spotting another case to support the use of aliases Comment : @evilive : this is actually not specific to Oracle .

I need to better understand the rules about when I can reference an outer table in a subquery and when and why that is an inappropriate request . I ve discovered a duplication in an Oracle SQL query I m trying to refactor but I m running into issues when I try and turn my referenced table into a grouped subQuery . The following statement works appropriately : .. . .. . Unfortunately table2 sometimes has duplicate records so I need to aggregate t2 first before I join it to t1 . However when I try and wrap it in a subquery to accomplish this operation suddenly the SQL engine can t recognize the outer table any longer . I know these are fundamentally different queries I m asking the compiler to put together but I m not seeing why the one would work but not the other . I know I can duplicate the table references in my subquery and effectively detach my subquery from the outer table but that seems like a really ugly way of accomplishing this task what with all the duplication of code and processing . Helpful References .. . .. . I found this fantastic description of the order in which clauses are executed in SQL Server : INNER JOIN ON vs WHERE clause http : stackoverflow.com questions 1018822 inner-join-on-vs-where-clause 1944492 1944492 . I m using Oracle but I would think that this would be standard across the board . There is a clear order to clause evaluation with FROM being first so I would think that any clause occuring further down the list would have access to all information previously processed . I can only assume my 2nd query somehow changes that ordering so that my subquery is being evaluated too early In addition I found a similar question asked Referencing outer query s tables in a subquery http : stackoverflow.com questions 2645485 referencing-outer-querys-tables-in-a-subquery but while the input was good they never really explained why he couldn t do what he is doing and just gave alternative solutions to his problem . I ve tried their alternate solutions but it s causing me other issues . Namely that subquery with the date reference is fundamental to the entire operation so I can t get rid of it . Questions .. . .. . I want to understand what I ve done here.. . Why can my initial subquery see the outer table but not after I wrap the entire statement in a subquery That said if what I m trying to do can t be done what is the best way of refactoring the first query to eliminate the duplication Should I reference table1 twice with all the duplication that requires Or is there probably a better way of tackling this problem Thanks in advance ------EDIT------ .. . .. . As some have surmised these queries above are not the actually query I m refactoring but an example of the problem I m running into . The query I m working with is a lot more complicated so I m hesitant to post it here as I m afraid it will get people off track . ------UPDATE------ .. . .. . So I ran this by a fellow developer and he had one possible explanation for why my subquery is losing access to t1 . Because I m wrapping this subquery in a parenthesis he thinks that this subquery is being evaluated before my table t1 is being evaluated . This would definitely explain the ORA-00904 : t1 . id : invalid identifier error I ve been receiving . It would also suggest that like arithmetic order-of-operations that adding parens to a statement gives it priority within certain clause evaluations . I would still love for an expert to weigh in if they agree disagree that is a logical explanation for what I m seeing here . Comment : A derived table can t be correlated . It must stand alone . Though you can join onto it . you can use APPLY where you need a sort of correlated derived table . Comment : Martin... . sincerely thank you Based on your comment I was able to do a little additional research and found that my query isn t actually pulling data how I originally thought . Also your advice to use Apply seems very applicable though for me syntax is a little different as I m using Oracle . Very much appreciate the advice - in fact if you submit it as an answer I ll mark it as the correct one . .. . Answer : So I figured this out based on the comment that Martin Smith made above THANKS MARTIN and I wanted to make sure I shared my discovery for anyone else who trips across this issue . Technical Considerations .. . .. . Firstly it would certainly help if I used the proper terminology to describe my problem : My first statement above uses a correlated-subquery : .. . .. . http : en.wikipedia.org wiki Correlated subquery .. . http : www.programmerinterview.com index.php database-sql correlated-vs-uncorrelated-subquery .. . .. . This is actually a fairly inefficient way of pulling back data as it reruns the subquery for every line in the outer table . For this reason I m going to look for ways of eliminating these type of subqueries in my code : .. . .. . https : blogs.oracle.com optimizer entry optimizer transformations subquery unesting part 1 .. . .. . My second statement on the other hand was using what is called an inline view in Oracle also known as a derived table in SQL Server : .. . .. . http : docs.oracle.com cd B19306 01 server.102 b14200 queries007.htm .. . http : www.programmerinterview.com index.php database-sql derived-table-vs-subquery .. . .. . An inline view derived table creates a temporary unnamed view at the beginning of your query and then treats it like another table until the operation is complete . Because the compiler needs to create a temporary view when it sees on of these subqueries on the FROM line those subqueries must be entirely self-contained with no references outside the subquery . Why what I was doing was stupid .. . .. . What I was trying to do in that second table was essentially create a view based on an ambiguous reference to another table that was outside the knowledge of my statement . It would be like trying to reference a field in a table that you hadn t explicitly stated in your query . Workaround .. . .. . Lastly it s worth noting that Martin suggested a fairly clever but ultimately inefficient way to accomplish what I was trying to do . The Apply statement is a proprietary SQL Server function but it allows you to talk to objects outside of your derived table : .. . .. . http : technet.microsoft.com en-us library ms175156 v SQL.105 .aspx .. . .. . Likewise this functionality is available in Oracle through different syntax : .. . .. . What is the equivalent of SQL Server APPLY in Oracle http : stackoverflow.com questions 1476191 what-is-the-equivalent-of-sql-server-apply-in-oracle .. . .. . Ultimately I m going to re-evaluate my entire approach to this query which means I ll have to rebuild it from scratch believe it or not I didn t create this monstrocity originally - I swear . A big thanks to everyone who commented - this was definitely stumping me but all of the input helped put me on the right track Comment : +1 Thinking of them as inline views explains the problem well . More recent versions of Oracle do support APPLY though http : technology.amis.nl 2013 06 26 oracle-database-12c-joining-and-outer-joining-with-collections Comment : Thanks for the info.. . I m still using 11G so that functionality is news to me Comment : nice answer but still unable to get the sharp edge between inline view and correlated query when to consider a query as this and when as that Comment : @osamayaccoub I see your confusion now.. . yes my subquery above had been on the JOIN and while that clause is an entity to itself for this case think of it as a subset of the FROM clause . Focus on how the parser will dissect my code and create a plan for execution . Evaluating the FROM and JOIN clauses will be it s very first steps as it will need to know what resources to manage . But as it is trying to pull in it s initial resources and create a temp table view behind the scenes to house my subquery data I am trying to refer to values that it has not yet evaluated . Comment : @osamayaccoub Martin described it best above.. . A derived table can t be correlated . I am trying to have the parser create a temp table for me as part of my FROM JOIN clauses.. . so correlation is not allowable .", "Question : I was trying to run a query like this on hive version 1.2.1 : .. . .. .

To know if it is possible Comment : Do you have a specific problem you re trying to solve or is this an exercise Comment : This syntax is not allowed in any database so I guess the answer is no . Postgres does do something quite similar where DML statements are allowed in CTEs . MySQL does not have any similar capability within a single statement . Comment : are you trying to generate a script maybe something like this select INSERT INTO customer.name VALUES Test Name from customer Comment : I guess his goal is to do an insert into a DB where his user has only SELECT rights Comment : @Ashton If you don t have access to insert or delete then you wouldn t be able to run the script after its generated . You could come up with a proc that would generate and execute the script and hand it off or schedule it via a user that does have the privileges . This has been the approach I ve used in the past when I needed to do mass updates inserts based on data and or criteria from DB tables . .. . Answer : You may have a select within an insert but not the other way around . A select within an insert statement could be used to copy values from a table to another . You are just writing into a table after a read from another .. . .. . But an insert within a select doesn t make sense What are you going to insert when you are running a select from a table or just reading data how is it possible to write when you are only allowed to read .. . .. . Your situation if you don t have access to run an insert then it doesn t matter where you put the statement you just can t because you aren t allowed to .. . .. . But if you are talking about your query-engine database wrapper not allowing a direct insert then its probably because it requires an application program to insert data into to rather than just a query as your engine doesn t already have the capability to perform that operation . Comment : You are right it does not make sense That is why I wanted to entertain the idea to see what else would come out of it . My curerent DBMS does not allow me to use anything but SELECT statements in it s compiler and I wanted a way around this . Thank you for your input answer" ] }

Object.equals is handled using Objects.equals in roughly the manner you mentioned .. . Object.hashCode is handled with Objects.hashCode like return Objects.hashCode id name .. .

I m not sure how to investigate how js2-mode is intercepting preventing the before-save-hooks from being triggered . Comment : Not a direct answer but you might like to try using either ws-trim ftp : ftp.lysator.liu.se pub emacs ws-trim.el or ws-butler https : github.com lewang ws-butler instead . These libraries can smartly tidy up only the lines you actually edit which prevents you from making unnecessary changes to other parts of the file . If you use version-control I would consider this mandatory to avoid committing irrelevant changes . Comment : Version of Emacs Version of js2-mode from GNU ELPA you haven t specified .

Of course I know that swank-js depends on js2-mode Can I just require js2-mode means not as major mode and add some extra settings to enable swank-js Any help is appreciated .

Comment : Thanks for you answer :", "Question : I just started to use js2-mode in Emacs and I found some variables like js2-global-externs and js2-additional-externs . The doc string says it is A list of any extern names you d like to consider always declared . I don t understand what extern means here . I only knew the extern keyword in C so I started to discover what extern means . I searched JavaScript extern Ecma-262 extern web browser extern but didn t get anything that looked promising . Can anyone point me in the right direction .. . Answer : The extern keyword has nothing to do with JavaScript . It s some configuration on which js2-mode relies on to define the language . For instance I believe that you could add your own global-variables js2-global-externs so that they get recognized . Have a look at this file https : code.google.com p js2-mode source browse trunk js2-externs.el r 57 Comment : Thanks .

Try turning that off with M-x or electric-indent-mode -1 . .. . Answer : M-x electric-indent-local-mode should do it if you re using Emacs-24.4 . Comment : Is there a way to automatically set this for all js2 buffers but leave all other buffers alone Comment : The answer I gave only works on the current buffer . So you can add it to your js2-mode-hook as in : add-hook js2-mode-hook lambda electric-indent-local-mode -1", "Question : I m trying out js2-mode which is a kind of javascript IDE in emacs . One of the features is syntax-error highlighting and style warnings . Since turning it on I ve noticed that I m getting this one warning all over my code : .. . .. . When I write a function whose responsibility is to call a callback I often do not explicitly add a return-value . Is that bad style For example : .. . .. . where the return only serves to ensure the rest of the function doesn t get executed . Is that better written as .. . .. . The latter style is the only way to get js2-mode to leave me alone . Or maybe it should be written as .. . .. . That also gives me a js2 pass but I have always found the former style to read better . Am I doing it wrong or is js2-mode too uptight Comment : Not returning a value from a callback is ONLY bad style if the caller of the callback is expecting a return-value from it . If no return-value is expected by the caller then it is pointless to return something in the callback . In your code you really ought to only use return statements when you re actually purposefully returning a value that will be used - otherwise it is very confusing to people reading your code what should be put in that return-value . Comment : How about using return to stop the execution a function to save on curly-braces and an indentation level Comment : A plain return statement by itself is fine . But return callback or return someAsyncMethod .. . makes it look like you are purposely returning a value which I would not recommend if there is no return-value from the function . In my opinion code clarity of intent is more important than saving a line or two of bracing . .. . Answer : The consensus at work and following from jfriend00 is that it should be written like this : .. . .. . js2-mode was right . My desire to write one-liners was making my code less clear .", "Question : null .. . Answer : I started using Emacs a couple weeks ago .

Answer : init https : github.com yiisoft yii2-app-advanced blob master init Yii Application Initialization Tool is available for Advanced Application Template only and written in procedural style not OOP . Unfortunately init does not raise any events so you can t add any event handlers to execute custom code . The easiest way to solve the problem is to modify init file itself but it s not good practice because changes can be lost on framework update file is included in git trackable files in framework core . My advice will be create separate console command http : www.yiiframework.com doc-2.0 guide-tutorial-console.html create-command for handling that and execute it right after php init : .. . .. . If you are using deploy tools such as Deployer http : deployer.org you can easily add your custom command for execution right after init .

Answer : The Yii2 guide has excellent documentation in this regard see Upgrade from v1 http : www.yiiframework.com doc-2.0 guide-intro-upgrade-from-v1.html .. . .. . I recently migrated couple of moderately complex applications from Yii 1.x to Yii 2.0 . There are two ways to go about it either you can run Yii 1.x and Yii 2 at the same time see using-yii-2-with-yii-1 http : www.yiiframework.com doc-2.0 guide-tutorial-yii-integration.html using-both-yii2-yii1 . Then migrate part by part while it is possible it was quite bit of pain like trying to rebuild the second floor while living on the third . Alternatively you can rewrite the entire application bottom up with the exact same functionality I found this to be much more efficient significant code could be reused with only minor modifications also that gave opportunity to tweak the design without changing functionality . The important thing is to ensure the exposed API i.e . the frontend UI functionality remains the same . It is always tempting to update functionality or change features during a rewrite however if you stick to strictly reimplementing everything for Yii2 then consider changing your API your migration will be smoother .", "Question : I m working with Yii2 Framework and already configured i18n component using this guide : http : thecodeninja.net 2014 12 i18n-with-yii-2-advanced-template .. . .. .

And there are some details for yii data Pagination http : www.yiiframework.com doc-2.0 yii-data-pagination.html component . Learn framework features and use it .

And in the same time die totally on following line : .. . .. . and display return completely blank page instead of correct error message I have a very strange troubles with Yii2 error handler ever since I started coding in Yii2 . Above code is one of examples . Another one is that redeclaring Yii namespace in migration causes command-line console to die ugly instead of displaying proper fatal-error https : github.com yiisoft yii2 issues 8206 . I ve been told https : github.com yiisoft yii2 issues 8206 issuecomment-96988544 that this problem is caused by my PHP configuration . But I found it hard to believe -- mainly because : .. . .. . I haven t changed anything in my XAMPP structure php.ini content etc . for past many many months I m actually still using old-good 1.8.1 version of XAMPP versioned without compliance to PHP version .. . .. . all metioned problems started about month ago when I started coding in Yii2 and happens only in Yii2-powered apps -- I can t reproduce any of above mentioned problems in any of my Yii1-powered projects . I agree that this must be something in my local installation of PHP because I have tested all of these examples in freshly-new installed XAMPP 5.6.8 and in its portable version . But since I can only reproduce this problem in Yii2-powered project and everything goes as good as it can in Yii1-powered application or under pure PHP then there must be some sort of nasty devil inside . Can someone help here or at least shed some light where should I start looking for Comment : Idk actually . I have XAMPP Version 1.8.3 with php 5.5.11 . Tested and for me php fatal errors handled properly . So it must be your local installation problem try another xamp or vagrant box maybe . Comment : have you set debug variable to true in web index.php defined YII DEBUG or define YII DEBUG true defined YII ENV or define YII ENV dev Comment : @arkoak Yes of course : .. . Answer : I found out that on certain environments when Yii2 handles a missing variable error it shows an error at the bottom of the debugger . Warning : var export does not handle circular references in vendor yiisoft yii2 helpers BaseVarDumper.php on line 187 .. . .. . Maybe that error is causing your environment to die on this . However this seems to be a bug . Also I found a workaround using the solution found in this Github Issue https : github.com yiisoft yii2 issues 3327 . It s not pretty but is a solution .

Comment : This is the best legitimate answer Comment : According to the W3C boolean attributes are defined by presence or absence of the attribute . jQuery provides the method .attr to manipulate attribute values . But how do we add an attribute without value The method you provide to test the presence of an attribute is not described in the jQuery documentation 1.8.2 . Do you know how to add an attribute with jQuery Comment : I agree this is the best answer using jQuery - very clear and concise . I did find myself wondering why jQuery doesn t just have a hasAttribute function and the answer is that native javascript already has one . Any HTML Dom Element has a method hasAttribute attributeName . So you could do : A 0 .hasAttribute myattr @chmike - I don t think you can add an empty attribute using jQuery functions but you can do it with the HTML Dom Element object in a similar way as follows : A 0 .setAttributeNode document.createAttribute myNewAttribute Comment : Just a comment that I like this answer but was confused about the comments asking how to add an attribute without a value .

Answer : Many answers and their examples are misleading . Encapsulation http : en.wikipedia.org wiki Encapsulation object-oriented programming is the packing of data and functions operating on that data into a single component and restricting the access to some of the object s components . Encapsulation means that the internal representation of an object is generally hidden from view outside of the object s definition .

Now is the class IsThisEncapsulation an example of Encapsulation Now would making the field age in the above class private achieve informaton hiding Could you please give me clear examples that will help me distinguish these concepts clearly Comment : is the class IsThisEncapsulation an example of Encapsulation you have not really encapsulated anything since you provide getters and setters that can read and write the state of your class directly.. . Comment : @assylias Making age public is what breaks encapsulation not providing getter and setter.. . Comment : @hyde I had not noticed that detail Indeed Comment : @hyde i read that encapsulation means bundling data and methods together if that is so the class that i have made IsThisEncapsulation does achieve encapsulation.Am i correct Or have i read about encapsulation incorrectly . Comment : @user1720616 For encapsulation to be meaningful you need some invariants conditions which must remain true . For age you could define invariant : age can t be negative . So if it s possible to set negative age instead of getting exception or whatever as it obviously is if age is public field then age is not encapsulated properly . Another might be if you have many fields which depend on each other so you can t just modify one field you need code which does proper modifications to all fields that need it . .. .

Answer : Encapsulation does not contradict with Dependency Inversion Principles in Object-Oriented Programming world . For example in a car design you will have an internal engine which will be encapsulated from outside world and also wheels that can be replaced easily and considered as outside component of the car . The car has specification interface to rotate the shaft of the wheels and the wheels component implements part that interact with the shaft . Here The internal engine represents the encapsulation process while the wheel components represent the Dependency Inversion Principles DIP in the car design . With DIP basically we prevent building a monolithic object and instead we make our object composable . Can you image you build a car where you cannot replace the wheels because they are built-in into the car . Also you can read more about Dependency Inversion Principles in more details in my blog Here http : kusnaditjung.blogspot.co.uk 2016 05 dependency-inversion-principle-dip.html .", "Question : If I understand correctly the typical mechanism for Dependency Injection is to inject either through a class constructor or through a public property member of the class .

Client code does not know implementation details still .", "Question : I ve read the other posts discussing abstraction and encapsulation but I m not confident I understand them or maybe I understand them but feel unsatisfied with the clarity of their content . Here are my understandings of abstraction and encapsulation . In what regards are they accurate inaccurate complete incomplete Abstractions are data types created by programmers to extend a language when primitive data types are insufficient . Like primitive data types abstractions have specifications which list the inputs they require and the outputs they return but the specifications do not overwhelm programmers with the methods functions and variables used to operate on the inputs . A class is an example of an abstraction . An API is another example of an abstraction . Encapsulation is the state of having abstract data types i.e . classes isolated from each other so their methods functions and variables do not conflict with each other and so programmers can easily reuse an existing class in other programs without being concerned that doing so would interfere with the rest of the program presuming the programmer correctly provides the required inputs and correctly handles the data that get returns . Comment : You seem to be quoting something - what .. . Answer : I ve never come across that definition of encapsulation before . That definition sounds more like what namespaces are for . I ve always read about encapsulation being purely about the ability to restrict access to certain components of your code such as access modifiers in OOP languages . However there seems to be a two definitions of encapsulation on wikipedia which is news to me : .. . .. . Encapsulation is the packing of data and functions into a single component . The features of encapsulation are supported using classes in most object-oriented programming-languages although other alternatives also exist . It allows selective hiding of properties and methods in an object by building an impenetrable wall to protect the code from accidental corruption . .. . In programming-languages encapsulation is used to refer to one of two related but distinct notions and sometimes to the combination thereof : .. . .. . 1 . A language mechanism for restricting access to some of the object s components . 2 . A language construct that facilitates the bundling of data with the methods or other functions operating on that data . .. . Some programming language researchers and academics use the first meaning alone or in combination with the second as a distinguishing feature of object-oriented programming while other programming-languages which provide lexical closures view encapsulation as a feature of the language orthogonal to object orientation . .. . The second definition is motivated by the fact that in many OOP languages hiding of components is not automatic or can be overridden thus information-hiding is defined as a separate notion by those who prefer the second definition . source https : en.wikipedia.org wiki Encapsulation computer programming .. . .. .

Encapsulation allows you to keep all the data and the functionality pertinent to an entity with this entity . Levels of visibility of this data is a related but not identical concept . E.g . an Employee object caries all employee data and functionality methods with it . Note that this is not enforced but enabled by the OO languages .

Answer : Does IoC always break encapsulation and therefore OOP No these are hierarchically related concerns . Encapsulation is one of the most misunderstood concepts in OOP but I think the relationship is best described via Abstract Data Types ADTs . Essentially an ADT is a general description of data and associated behaviour . This description is abstract it omits implementation details . Instead it describes an ADT in terms of pre- and post-conditions . This is what Bertrand Meyer calls design-by-contract . You can read more about this seminal description of OOD in Object-Oriented Software Construction http : amzn.to 1claOin . Objects are often described as data with behaviour . This means that an object without data isn t really an object . Thus you have to get data into the object in some way . You could for example pass data into an object via its constructor : .. . .. . Another option is to use a setter function or property . I hope we can agree that so far encapsulation is not violated . What happens if we change bar from an integer to another concrete class The only difference compared to before is that bar is now an object instead of a primitive . However that s a false distinction because in object-oriented design an integer is also an object . It s only because of performance optimisations in various programming-languages Java C etc . that there s an actual difference between primitives strings integers bools etc . and real objects . From an OOD perspective they re all alike . Strings have behaviours as well : you can turn them into all-upper-case reverse them etc . Is encapsulation violated if Bar is a sealed final concrete class with only non-virtual members bar is only data with behaviour just like an integer but apart from that there s no difference . So far encapsulation isn t violated . What happens if we allow Bar to have a single virtual member Is encapsulation broken by that Can we still express pre- and post-conditions about Foo given that Bar has a single virtual member If Bar adheres to the Liskov Substitution Principle https : en.wikipedia.org wiki Liskov substitution principle LSP it wouldn t make a difference . The LSP explicitly states that changing the behaviour mustn t change the correctness of the system . As long as that contract is fulfilled encapsulation is still intact . Thus the LSP one of the SOLID principles https : en.wikipedia.org wiki SOLID object-oriented design of which the Dependency Inversion Principle https : en.wikipedia.org wiki Dependency inversion principle is another doesn t violate encapsulation it describes a principle for maintaining encapsulation in the presence of polymorphism . Does the conclusion change if Bar is an abstract base-class An interface No it doesn t : those are just different degrees of polymorphism . Thus we could rename Bar to IBar in order to suggest that it s an interface and pass it into Foo as its data : .. . .. . bar is just another polymorphic object and as long as the LSP holds encapsulation holds . TL DR .. . .. . There s a reason SOLID is also known as the Principles of OOD . Encapsulation i.e . design-by-contract defines the ground rules . SOLID describes guidelines for following those rules .", "Question : Interviewer : What is encapsulation and how do you achieve it in Java .. .

Answer : You are asking about only two of them but Object Oriented Analysis and Design OOAD is actually based on four principles . A mnemonic to remember the four principles is A PIE . Abstraction : means that you only incorporate those features of an entity which are required in your design . So if every bank account has an opening date but your application doesn t need to know an account s opening date then you simply don t add the OpeningDate field in your Object-Oriented Design of the BankAccount class . Abstraction in OOAD has nothing to do with abstract classes in programming . By this principle your entities are an abstraction of what they actually are . You design an abstraction of Bank Account down to only that level of detail that your application s needs . Inheritance : is the principle that saves you from writing those functionalities that you can receive from someone else . Just like you may inherit your parents wealth you may inherit fields and methods from your parent class . So taking everything that parent class has and then adding something more if need be is inheritance . Don t go looking for inheritance in your Object Oriented Design . Inheritance will present itself . Polymorphism : is a consequence of inheritance . Inheriting a method from parent is useful but being able to modify a method if the situation demands is polymorphism . You may implement a method in the subclass with exactly the same signature as in parent class so that when called the method from child class is executed . This is polymorphism . Encapsulation : means bundling the related functionality together and giving access to only the needful . This principle is the basis of designing classes in Object Oriented Design where : .. . .. . you put related data and methods together and .. . not all the pieces of data and methods may be public . .. . .. . People who argue that Abstraction of OOAD results in the abstract keyword of OOP .. . Well that is simply not correct . Example : When you design a University in an application using object oriented principles you only design an abstraction of the university . Even though there is usually one cash dispensing ATM in almost every university you may not incorporate that fact if it s not needed for your application . And now though you have designed only an abstraction of the university you are not required to put abstract in your class declaration . Your abstract design of university will be a normal class in your application .", "Question : I am preparing for an interview and decided to brush up my OOP concepts .

Am I correct in identifying this tradeoff How do you deal with this issue Please also see my answer to my own question below . Comment : this is a very smart question imho Comment : Answering this question first requires an argument about what encapsulation means . Comment : Encapsulation is maintained by the interfaces . They expose the essential characteristics of the object and hide details such as dependencies . This allows us to open-up the classes to some extent as to provide a more flexible configuration . .. . Answer : There is another way of looking at this issue that you might find interesting . When we use IoC dependency-injection we re not using OOP concepts . Admittedly we re using an OO language as the host but the ideas behind IoC come from component-oriented software-engineering not OO . Component software is all about managing dependencies - an example in common use is .NET s Assembly mechanism . Each assembly publishes the list of assemblies that it references and this makes it much easier to pull together and validate the pieces needed for a running application . By applying similar techniques in our OO programs via IoC we aim to make programs easier to configure and maintain . Publishing dependencies as constructor parameters or whatever is a key part of this . Encapsulation doesn t really apply as in the component service oriented world there is no implementation type for details to leak from . Unfortunately our languages don t currently segregate the fine-grained object-oriented concepts from the coarser-grained component-oriented ones so this is a distinction that you have to hold in your mind only : Comment : Positively great answer Comment : Encapsulation is not just a piece of fancy terminology . It is a real thing with real benefits and it doesn t matter if you consider your program to be component oriented or object oriented . Encapsulation is supposed to protect the state of your object component service whatever from being changed in unexpected ways and IoC does take away some of this protection so there s definitely a tradeoff . Comment : Arguments supplied through a constructor still fall within the realm of expected ways in which the object may be changed : they re explicitly exposed and invariants around them are enforced . Information hiding is the better term for the kind of privacy you re referring to @RonInbar and it s not necessarily always beneficial it makes the pasta harder to untangle - .", "Question : In interviews I have been asked to explain the difference between abstraction and encapsulation .

In relation to this topic we were debating whether these principles violate one of the pillars of OOP namely Encapsulation . My understanding of these things is : .. . .. . The Dependency Inversion Principle implies that objects should depend upon abstractions not concretions - this is the fundamental principle upon which the Inversion of Control pattern and Dependency Injection are implemented . Inversion of Control is a pattern implementation of the Dependency Inversion Principle where abstract dependencies replace concrete dependencies allowing concretions of the dependency to be specified outside of the object . Dependency Injection is a design pattern that implements Inversion of Control and provides dependency-resolution . Injection occurs when a dependency is passed to a dependent component . In essence the Dependency Injection pattern provides a mechanism for coupling dependency abstractions with concrete implementations . Encapsulation is the process whereby data and functionality that is required by a higher level object is insulated away and inaccessible thus the programmer is unaware of how an object is implemented . The debate got to a sticking point with the following statement : .. . .. . IoC isn t OOP because it breaks Encapsulation .. . .. . Personally I think that the Dependency Inversion Principle and the Inversion of Control pattern should be observed religiously by all OOP developers - and I live by the following quote : .. . .. . If there is potentially more than one way to skin a cat then do not behave like there is only one . Example 1 : .. . .. . Here we see an example of encapsulation . The programmer only has to call Main and the cat will be skinned but what if he wanted to skin the cat with say a set of razor sharp teeth Example 2 : .. . .. . Here we observe the Dependency Inversion Principle and Inversion of Control since an abstract ICatSkinner is provided in order to allow concrete dependencies to be passed in by the programmer . At last there is more than one way to skin a cat .. . .. . The quarrel here is does this break encapsulation technically one could argue that .SkinTheCat is still encapsulated away within the Main method call so the programmer is unaware of the behavior of this method so I do not think this breaks encapsulation .

In fact I d go as far as to say that : .. . .. . Encapsulation and Inversion of Control coincide with each other happily allowing programmers to pass in only the concretions of a dependency whilst hiding away the overall implementation via encapsulation .

Answer : Is IoC a direct implementation of the Dependency Inversion Principle The two are related in a way that they talk about abstractions but that s about it . Inversion of Control is : .. . .. . a design in which custom-written portions of a computer program receive the flow of control from a generic reusable library source https : en.wikipedia.org wiki Inversion of control .. . .. . Inversion of control is allowing us to hook our custom code into the pipeline of a reusable library . In other words Inversion control is about frameworks . A reusable library that does not apply Inversion of Control is merely a library . A framework is a reusable library that does apply Inversion of Control . Do note that we as developers can only apply Inversion of Control if we are writing a framework ourselves you can t apply inversion-of-control as an application developer . We can and should however apply Dependency Inversion Principle and the Dependency Injection pattern . Does IoC always break encapsulation and therefore OOP Since IoC is just about hooking into the pipeline of a framework there is nothing that s leaking here . So the real question is : does Dependency Injection break encapsulation . The answer to that question is : no it does not . It doesn t break encapsulation because of two reasons : .. . .. . Since the Dependency Inversion Principles states that we should program against an abstraction a consumer will not be able to access the internals of the used implementation and that implementation will therefore not be breaking encapsulation to the client . The implementation might not even be known or accessible at compile-time because it lives in an unreferenced assembly and the implementation can in that case not leak implementation details and break encapsulation . Although the implementation accepts the dependencies it requires throughout its constructor those dependencies will typically be stored in private fields and can t be accessed by anyone even if a consumer depends directly on the concrete type and it will therefore not break encapsulation . Should IoC be used sparingly religiously or appropriately Again the question is Should DIP and DI be used sparingly . In my opinion the answer is : NO you should actually use it throughout the application . Obviously you should never apply things religiously . You should apply SOLID principles and the DIP is a crucial part of those principles . They will make your application more flexible and more maintainable and in most scenarios it is very appropriate to apply the SOLID principles . What is the difference between IoC and an IoC container Dependency Injection is a pattern that can be applied either with or without a IoC container . An IoC container is merely a tool that can help building your object graph in a more convenient way in case you have an application that applies the SOLID principles correctly . If you have an application that doesn t apply the SOLID principles you will have a hard time using a IoC container . You will have a hard time applying Dependency Injection . Or let me put it more broadly you will have a hard time maintaining your application anyway . But in no way an IoC container is a required tool . I m developing and maintaining an IoC container for .NET but I don t always use a container for all my applications . For the big BLOBAs boring line of business applications I often use a container but for smaller apps or windows-services I don t always use a container . But I do almost always use Dependency Injection as a pattern because this is the most effective way to adhere to DIP . Note : Since an IoC container helps us in applying the Dependency Injection pattern IoC container is a terrible name for such library . .. . .. . But despite of anything I said above please note that : .. . .. . in the real world of the software developer usefulness trumps theory from Robert C .

Answer : Encapsulation is only broken if a class has both the responsibility to create the object which requires knowledge of implementation details and then uses the class which does not require knowledge of these details . I ll explain why but first a quick car anaology : .. . .. . When I was driving my old 1971 Kombi I could press the accelerator and it went slightly quicker . I did not need to know why but the guys who built the Kombi at the factory knew exactly why . But back to the coding . Encapsulation is hiding an implementation detail from something using that implementation . Encapsulation is a good thing because the implementation details can change without the user of the class knowing . When using dependency-injection constructor-injection is used to construct service type objects as opposed to entity value-objects which model state . Any member variables in service type object represent implementation details that should not leak out . e.g . socket port-number database credentials another class to call to perform encryption a cache etc . The constructor is relevant when the class is being initially created . This happens during the construction-phase while your DI container or factory wires together all the service objects . The DI container only knows about implementation details . It knows all about implementation details like the guys at the Kombi factory know about spark plugs . At run-time the service object that was created is called apon to do some real work . At this time the caller of the object knows nothing of the implementation details . That s me driving my Kombi to the beach . Now back to encapsulation . If implementation details change then the class using that implementation at run-time does not need to change . Encapsulation is not broken . I can drive my new car to the beach too . Encapsulation is not broken . If implementation details change the DI container or factory does need to change . You were never trying to hide implementation details from the factory in the first place . Comment : How would you unit test your factory And that means the client needs to know about the factory in order to get a working car which means you need a factory for each other object in your system .", "Question : In interviews I have been asked to explain the difference between abstraction and encapsulation .

Is IoC a direct implementation of the Dependency Inversion Principle Does IoC always break encapsulation and therefore OOP Should IoC be used sparingly religiously or appropriately What is the difference between IoC and an IoC container Comment : Being a question about conceptual questions about software development you might have more luck getting this answered on programmers.stackexchange.com http : programmers.stackexchange.com .

Answer : Summing up the question : .. . .. . We have the ability for a Service to instantiate its own dependencies . Yet we also have the ability for a Service to simply define abstractions and require an application to know about the dependent abstractions create concrete implementations and pass them in . And the question is not Why we do it Because we know there is a huge list of why . But the question is Doesn t option 2 break encapsulation .. . .. . My pragmatic answer .. . .. . I think Mark is the best bet for any such answers and as he says : No encapsulation isn t what people think it is . Encapsulation is hiding away implementation details of a service or abstraction . A Dependency isn t an implementation detail . If you think of a service as a contract and its subsequent sub-service dependencies as sub-contracts etc etc chained along then you really just end up with one huge contract with addendums . Imagine I m a caller and I want to use a legal service to sue my boss . My application would have to know about a service that does so . That alone breaks the theory that knowing about the services contracts required to accomplish my goal is false . The argument there is.. . yeah but I just want to hire a lawyer I don t care about what books or services he uses . I ll get some random dood off the interwebz and not care about his implementation details.. . like so : .. . .. . But it turns out other services are required to get the job done such as understanding workplace law . And also as it turns out.. . I am VERY Interested in the contracts that lawyer is signing under my name and the other stuff he s doing to steal my money . For example.. . Why the hell is this internet lawyer based in South Korea How will THAT help me That isn t an implementation detail that s part of a dependency chain of requirements I m happy to manage . Now all I know is that I have a contract which has other contracts which might have other contracts . I am very well responsible for those contracts and not their implementation details . Though I am more than happy to sign those contracts with concretions that are relevant to my requirements . And again I don t care about how those concretions do their jobs as long as I know I have a binding contract that says we exchange information in some defined way . Comment : Encapsulation is hiding away implementation details of a service or abstraction . - exactly and in your second example you have made these implementation details explicit instead of hiding them . In fact we can keep going and say that ca workplace law is not decoupled enough-let s add county services in there and maybe the specific case law that should be referenced . It is nice that we can change all this on the fly but now you have moved the burden to the caller for something that should be handled by a dedicated class instead . I don t know if this breaks encapsulation or just YAGNI . Comment : Creating concrete instantiations of abstractions or instead of abstractions is not implementation . The methods defined in those classes and or abstractions are a contract and the code within a method defined in a contract is the implementation . And so since the Composition Root is only responsible for filling abstractions with concrete instantiations which inside them have contracted methods which inside them have implementations we never expose implementation to the caller . Fulfilling Contracts does not show us the code in the methods in the classes that implement those contracts Comment : Though yes I do show where the implementation detail is.. . in both example 2 as well as example 1 . And in both cases they are hidden from main", "Question : Here is a class Encapsulate which has public property and a public-method . Is the OOP concept Encapsulation followed here I am sure that it is applicable as both are bonded together in a class may be we can call it weak encapsulation but there is encapsulation . But I don t know how to prove it because my searches showed that class-properties should be private . Update : What in case of default access-specifier . Comment : I don t know if this is really correct but usually I say that data hiding and encapsulation are related but not the same . Comment : This might be interesting : programmers.stackexchange.com questions 173547 http : programmers.stackexchange.com questions 173547 what-is-the-difference-between-data-hiding-and-encapsulation Comment : If I am binding property and methods using public access-specifier than also they are hidden from other classes and bounded together That s what encapsulation is except other classes instantiate them or extend them . Comment : Possible duplicate of stackoverflow.com questions 1020749 http : stackoverflow.com questions 1020749 what-are-public-private-and-protected-in-object-oriented-programming The very first answer to that question probably answers your question . This site has a search function use it before posting a new question . Comment : @ Raedwald : Thanks for the info but I am aware of it and the link you provided is not answering my question at least I couldn t find what I wanted . .. . Answer : Heres another example that Encapsulation is Hiding data .. . .. . Software objects are conceptually similar to real-world objects : they too consist of state and related behavior . An object stores its state in fields variables in some programming-languages and exposes its behavior through methods functions in some programming-languages . Methods operate on an object s internal state and serve as the primary mechanism for object-to-object communication . Hiding internal state and requiring all interaction to be performed through an object s methods is known as data encapsulation a fundamental principle of object-oriented programming . Which basically means you should change the access modifiers of the properties to private and allow access to the properties through methods .. . .. .

Comment : @Angew Yes but as a function-parameter not as a template argument in a template-id . Comment : I have a sneaking suspicion that identity T is rejected by Clang because it triggers an overriding check of the form is the function-parameter an rvalue-reference if so if it refers to anything other than a plain template parameter it s not a forwarding-reference . Since identity T and forwarding-reference T from your other question don t contain the rvalue-reference syntax at the top level in the function-parameter they fall through to further processing . This is just a shot in the dark I haven t looked at the code . .. . Answer : It is not a forwarding-reference . C++14 n4140 14.8.2.1 3 emphasis mine : .. . .. . .. . If P is an rvalue-reference to a cv-unqualified template parameter and the argument is an lvalue the type lvalue reference to A is used in-place of A for type deduction . This is the piece of the standard which specifies how forwarding references work . P the type of the function-parameter is of type rvalue-reference to identity T . identity T is the type of the template parameter but it is not a template parameter itself so the forwarding-reference deduction rule does not apply . We can also look at what 14.5.7 2 has to say about alias templates : .. . .. . When a template-id refers to the specialization of an alias template it is equivalent to the associated type obtained by substitution of its template-arguments for the template-parameters in the type-id of the alias template . So the substituted alias is equivalent to the type of T but 14.8.2.1 3 reads reference to .. . template parameter not reference to .. . the type of a template parameter . Comment : If we assume the implementation is free to substitute the alias template with actual type it points to before the template argument type deduction takes place or something else not sure how to call it I m referring to what GCC presumably does this paragraph still applies doesn t it - I might be wrong I just don t know . Comment : @MarcAndreson Any reason why we should be able to assume that Comment : @MarcAndreson Per 14.5.7 2 When a template-id refers to the specialization of an alias template it is equivalent to the associated type obtained by substitution of its template-arguments for the template-parameters in the type-id of the alias template . Again it is equivalent to the type but the forwarding-reference ruling speaks about template parameters not their types .

Why var2 is not rvalue-reference but f and var2 are rvalue references Comment : I d recommend reading this article https : isocpp.org blog 2012 11 universal-references-in-c11-scott-meyers on forwarding references previously known as universal references . Comment : add auto var3 10 as an rvalue-reference Comment : Because named rvalue references are lvalues . Comment : lvalue reference and rvalue-reference refer to how a reference is bound . After binding it s just a reference there is no longer any distinction other than the result-of decltype . Please update your question to show how you are determining not rvalue-reference .. . Answer : Once the type of the initializer has been determined the compiler determines the type that will replace the keyword auto using the rules for template argument deduction from a function-call see template argument deduction Other contexts for details . The keyword auto may be accompanied by modifiers such as const or which will participate in the type deduction . For example given .. . .. . The type of i is exactly the type of the argument u in an imaginary .. . .. . If the function-call f expr was compiled . In general it can be think as below . Therefore auto may be deduced either as an lvalue reference or rvalue-reference according to the initializer . In your case imaginary template would look like .. . .. . Here var1 is named rvalue which is being treated as lvalue so var2 will be deduced as lvalue .

Any thoughts Comment : queue.push back std : : forward item there is no reason to forward a reference to a constant T . -- The reason for the error is that you have to supply the template argument for std : : forward manually : std : : forward T t since it is meant to restores the value category of t if t is a forwarding-reference . Comment : Thanks . I removed const and added the template argument and it solved the problem . If you add your comment as an answer I ll accept it . Comment : I think you should use void push T item without const and as a universal-reference . And call forward T with the explicit T . If you want to keep the const you should also add it in the call to forward const T . See isocpp.org blog 2012 11 http : isocpp.org blog 2012 11 universal-references-in-c11-scott-meyers for more details about the mess with different kind of references . .. . Answer : Value categories like lvalue and rvalue are properties of expressions . Expressions that name variables are always lvalue-expressions even if they name a variable that has the type rvalue-reference to some type . We use lvalue-reference and rvalue-references to bind different categories of expressions : Per convention we treat lvalue-references as being bound to lvalues and rvalue-references as being bound to rvalues . std : : forward is intended to restore the value category of what we assume a reference refers to . For example : .. . .. . std : : forward being an ordinary function cannot restore the value category merely by using the argument . Both arguments are lvalue-expressions . You have to specify which value category you want to restore by manually supplying the template-argument . This makes only sense if we have a reference where we don t know a priori whether it s an rvalue-reference or an lvalue-reference . That is the case-when writing a function that uses perfect-forwarding with forwarding references . By the way we want to restore the value category to allow another function to move from the argument we have received . If we receive an rvalue argument we want to pass on an rvalue to allow the called function to move . .. . .. . For a function like the one in the OP : .. . .. . We know that item has the type lvalue reference to const T . Therefore we don t need std : : forward : .. . .. . If we add another overload : .. . .. . we still don t need std : : forward since the type of that parameter item is always rvalue-reference to T assuming T is not a reference-type : .. . .. . Only if we have something like .. . .. . where forwarding-reference U can be either an lvalue-reference or an rvalue-reference then we need std : : forward : .. . .. . Due to implementation details we must write the above as : .. . .. . Note that the above U item is not an rvalue-reference but a forwarding-reference . To get a forwarding-reference you need to have a function template with some template type-parameter X and a function-parameter of the form X x .

Answer : The official name is not universal-reference but forwarding-reference http : stackoverflow.com questions 33904462 whats-the-standard-official-name-for-universal-references . The Standard http : www.open-std.org jtc1 sc22 wg21 docs papers 2016 n4582.pdf states that only rvalue references to cv-unqualified template parameters fall in this category : .. . .. . 14.8.2.1 Deducing template arguments from a function-call temp.deduct.call .. . .. . 3 If P is a cv-qualified type the top level cv-qualifiers of P s type are ignored for type deduction . If P is a reference-type the type referred to by P is used for type deduction . A forwarding-reference is an rvalue-reference to a cv-unqualified template parameter . If P is a forwarding-reference and the argument is an lvalue the type lvalue reference to A is used in-place of A for type deduction . Example : .. . .. . .. . template class T int f T heisenreference .. . template class T int g const T .. . int i .. . int n1 f i calls f int int .. . int n2 f 0 calls f int int .. . int n3 g i error : would call g int const int which .. . would bind an rvalue-reference to an lvalue .. . .. . .. . end example .. . .. . Allowing const T to behave as forwarding references would make it impossible to overload a template function who takes only an rvalue-reference as parameter . Update : as @HowardHinnant mentions in the comments const T does have its uses see also this Q A http : stackoverflow.com q 4938875 819272 . Comment : To tie back to the part of Item 24 in Effective Modern C++ that confused the OP Scott describe loosely universal references to be rvalue references in a type deducing context . The first non-emphasized sentence in the 14.8.2.1 standard quote above If P is a cv-qualified type the top level cv-qualifiers of P s type are ignored for type deduction clearly explains Scott s statement that Even the simple presence of a const qualifier is enough to disqualify a reference from being universal quote from book Item 24 . Comment : @dfri Thanks I didn t have a digital copy of EMC++ nearby . Comment : More motivation as to the why : Sometimes we need to say : Don t bind to an rvalue only to lvalues : template class T void cref const T delete . Comment : @HowardHinnant updated with a link-to another Q A where you explained that in depth tnx Comment : allowing const T to behave as forwarding references would lead to binding rvalue references to lvalues . strictly speaking this is not true . If const T is allowed to use as forwarding-reference we would deduce T as int in g i then collapse to const int which binds const lvalue refere to lvalue . The problem is that we would have no way to overload a template function who takes only rvalue-reference as parameter if both T and const T are allowed to use as forwarding references .", "Question : Consider this code : .. . .. .

According to the rules from above if T s type is rvalue-reference it will collapse to rvalue-reference if T s type is lvalue reference it will collapse to lvalue reference . So why std : : forward have two different signatures one for lvalue reference and one for rvalue-reference am I missing something Comment : They re called forwarding references these days . Comment : What is T is that supposed to be T .. . Answer : My question is if universal-reference type can be deduced why do I still need to call forward Because as soon as you give a name to the parameter param it is an lvalue even if the function was called with an rvalue so it wouldn t be forwarded as an rvalue unless you use forward T .. . .. . Why without forwarding tmp s correct c tor won t be called even if T s type was deduced . Because param is an lvalue . To restore the value category of the argument passed to foo you need to cast it back to string or string which means you need to know the type T was deduced as and use forward to do the cast . So why std : : forward have two different signatures one for lvalue reference and one for rvalue-reference am I missing something It was changed by http : www.open-std.org jtc1 sc22 wg21 docs papers 2010 n3143.html .. . .. .

The problem with your suggested version is that if you say forward string then the parameter T is not deduced so doesn t function as a forwarding-reference which means that T can t bind to an lvalue and it needs to be able to bind to an lvalue in order for forward string param to work because param is an lvalue there . Comment : According to your answer foo s param is an lvalue when you call forward with lvalue you get lvalue . So how rvalue type is preserved here BTW according to Scott Meyers foo s signature implies that param is universal-reference . Comment : The rvalue-ness is lost inside the body of foo because param is an lvalue there but then you restore the rvalue type using forward . Comment : And they are called forwarding references http : isocpp.org files papers N4164.pdf now not universal references . Comment : So if forward manages to restore the correct type of param which is preserved within foo s body why in my example tmp s c tor can t do implicitly the same Comment : Because you have to explicitly tell forward the type you want it to cast to i.e . you must call forward T param not just forward param . The explicit type there is explicit and cannot be deduced implicitly . If you don t use forward to restore the rvalue-ness then it is lost it can t be restored by another function that gets passed an lvalue it has no way to know that is was an rvalue two levels up the stack .", "Question : I looked recently at this video https : youtu.be qwXq5MqY2ZA explaining the ideas of concepts lite in C++ which are likely to appear this year as a TS . Now I also learned about universal references forwarding references as described here http : isocpp.org blog 2012 11 universal-references-in-c11-scott-meyers and that T can have two meanings depending on the context i.e . if type deduction is being performed or not . This leads naturally to the question how concepts will interact with universal references To make it concrete in the following example we have .. . .. . and .. . .. . But what happens if we use concepts Especially the last example bothers me a bit since there are two conflicting principles . First a concept used in this way is supposed to work just as a type and second if T is a deduced type T denotes a universal-reference instead of an rvalue-reference . Thanks in advance for clarification on this .. . Answer : T always has the same meaning -- it is an rvalue-reference to T . The interesting thing happens when T itself is a reference . If T X then T X . If T X then T X . The rule that an rvalue-reference to an lvalue reference is an lvalue reference is what allows the forwarding-reference technique to exist . This is called reference collapsing1 . So as for .. . .. . this depends on what Number T means . If Number T permits lvalue references to pass then that T will work like a forwarding-reference . If not T it will only bind to rvalues . As the rest of the examples are last I checked defined in terms of the first example there you have it . There may be additional magic in the concepts specification but I am not aware of it . .. . .. . 1 There is never actually a reference-to-a-reference . In fact if you type int y 3 int x y that is an illegal expression : but using U int U x y is perfectly legal as reference collapsing occurs . An analogy to how const works sometimes helps . If T const x is const regardless of if T is const . If T const is const then T const x is also const . And T const const x is const as well . The const ness of x is the max of the const ness of the type T and any local modifiers . Similarly the lvalue-ness of a reference is the max of the lvalue-ness of the T and any local modifiers . Imagine if the language had two keywords ref and lvalue . Replace with lvalue ref and with ref . The use of lvalue without ref is illegal under this translation. . .. . .. . T means T ref . If T was int lvalue ref then reference collapsing results in int lvalue ref ref - int lvalue ref which translates back as int . Similarly T translates to int lvalue ref lvalue ref - int lvalue ref and if T int then T translates to int ref lvalue ref - int lvalue ref - int .

Only an rvalue-reference to a CV-unqualified template parameter can be deduced as an l-value reference in this manner .

Comment : Traits are pretty cool I haven t used them that much but they ve been quite useful when I needed them . Ultimately in what I was working on I was able to use another type-parameter that could be passed as const to supply the template template parameter so was able to specify the argument type as a plain parameter kind of like Piotr s solution actually and asked the question more out of curiosity than needing a specific solution but this would be useful for situations where that s not doable .", "Question : I am reading Effective modern C++ by Scott Meyers .. . .. .

So my question is : is it possible to make this code forwarding referencable Comment : What about the linked answer is insufficient When you re explicitly providing the template arguments the overload isn t viable . .. . Answer : I will add a bit of details regarding @TartanLlama answer on why your code fails to compile even without the explicit template parameters but also why in my own opinion your code is dangerous . In the following I will use only a simple type T instead of your parameter pack Args.. . because it is simpler to explain and does not change the meaning . A bit of reminder on forwarding references.. . .. . .. . First let s take a simpler example than yours with simply the following : .. . .. . Now let s instanciate f from various sources let s assume with have the following variables : .. . .. . ...then : .. . .. . You should be wondering : Why is the first instanciation f std : : string instead of f std : : string but the standard tells you 14.8.2.1 3 temp.deduct.call : .. . .. . If P is a forwarding-reference and the argument is an lvalue the type lvalue reference to A is used in-place of A for type deduction . Back to our initial snippet Now let s complicate a bit our example : .. . .. . And one instantiation : .. . .. . The above is equivalent to your example and will fails to compile but why.. . Well as explained above when you have an lvalue the deduced type for T is T not T and thus the type deduction fails for A T because the compiler is expecting A std : : string and you are giving a A std : : string . So now we know that we have to do the following : .. . .. . Why is it dangerous Ok so now this should be good : .. . .. . But it is not.. . Because when T is deduced as a rvalue-reference T is simply T so the compiler is expecting A std : : string . So here is the problem : You are going to give a rvalue to a method that is going to forward it to a function expecting an lvalue . That s not wrong but it is probably not what you d have expected . How to deal with it The first possibility is to force the type of the first parameter regardless of the deduced type for T e.g . : .. . .. . But note : .. . .. . 1 . You would have to add more stuff to deal with const . 2 . One may wonder the usefulness of T when the type of the first argument is fixed in your case at least . The second possibility warning : I don t know if this is standard is to move the first parameter at the end and then deduce the type from t : .. . .. . Now you have an exact match between the deduced type for T and the expected type for A . Unfortunately I don t know how to make the above work with variadic templates.. . Comment : Thanks for your answer . I have still some doubts : 1 . f s instanciate f std : : string it s because of the infamous collapsing rule where A becomes A right 2 . In your solution I didn t get A decltype std : : forward T t 3 . What do you mean by warning : I don t know if this is standard and what could be the problem with that 4 . Your esample is not a little bit different since we are using template typename T1 typename T2 according to @TartanLlama s solution Comment : @justHelloWorld 1 . Not really it s because of the quoted standard part : If you have a templated function waiting for a forwarding-reference T and you are giving it an lvalue s in this case then the deduced argument template will be T and not T even for the other parameters . This is a different behaviour than if you pass an rvalue in which case the deduced parameter is still T for the other arguments . Comment : @justHelloWorld 2 . Instead of using T for the template argument you can used the deduce type for t which can be retrieved using decltype and std : : forward will be T if the given parameter is an lvalue and T if it s an rvalue . 3 . I simply mean that I don t know if you can use an parameter name in the definitiion of a following parameter . 4 . I was extending on your code why it does not work and why it may behave strangly not on the proposed code by Tartan . Comment : By your answer for point 4 . seems like @TartanLlama code could be a working solution or am I wrong Comment : @justHelloWorld Tartan code will basically work the same as the code with std : : remove reference but it is not what you want I think I will add a bit at the end of my answer to explain why .", "Question : I know that if a variable or parameter is declared to have type T for some deduced type T that variable or parameter is widely called a universal-reference . The term universal-reference was introduced by Scott Meyers in his original talk Universal References in C++11 https : channel9.msdn.com Shows Going+Deep Cpp-and-Beyond-2012-Scott-Meyers-Universal-References-in-Cpp11 . However I wonder what s the official standard term for universal references . .. . Answer : Overview .. . .. . It is known that since C++11 a parameter of type T is called an rvalue-reference ISO IEC 14882 : 2011 8.3.2 p2 References dcl.ref . That is unless T is a template parameter type or auto or a typedef for some lvalue reference-type . examples : .. . .. . .. . template typename T .. . void foo T p - T is a template parameter .. . .. . .. . .. . .. . auto p expression .. . .. . .. . Although technically T in the examples above is still an rvalue-reference its behaviour differs significantly from a regular one . Naturally you would ask why this special case doesn t have a special syntax . The answer is that the syntax was intentionally overloaded for this special construct by the C++ committee . However they missed to name this special case . In the absence of a distinct name for this particular construct Scott Meyers http : www.aristeia.com coined the widely known term name universal references https : isocpp.org blog 2012 11 universal-references-in-c11-scott-meyers . The committee however decided that this name is not proper for a number of reasons . As such the proposal N4164 http : www.open-std.org jtc1 sc22 wg21 docs papers 2014 n4164.pdf made by Herb Sutter https : en.wikipedia.org wiki Herb Sutter Bjarne Stroustrup https : en.wikipedia.org wiki Bjarne Stroustrup and Gabriel Dos Reis http : www.axiomatics.org gdr proposed to change the name to Forwarding References . The name Forwarding References had the most support in informal discussions among committee members including the authors of the proposal mentioned earlier . Interestingly enough it was Scott Meyers himself that introduced that term in his original Universal References talk . However later he decided to go along with the name universal references . For this decision played role the fact that at the time he didn t think that the term forwarding references included also the auto case . Why not universal references According to the proposal the term Universal references although is a reasonable name with an obvious meaning it happens to be wrong in several aspects . A universal-reference must mean the following : .. . .. . A reference that can be used everywhere or .. . A reference that can be used for everything or .. . something similar . Obviously this is not the case nor is the appropriate use of this construct . Furthermore this name would encourage many people to consider that something having such a name is meant to be used universally . Something that the committee considered it a bad thing . Moreover universal references aren t even really references per se but rather a set of rules for using references in a particular way in a particular context with some language support for that use and that use is forwarding . Why auto is Also Considered a Forwarding case .. . .. . auto is also considered a forward case since it follows the reference collapsing rules http : en.cppreference.com w cpp language reference . For example in : .. . .. . Generic lambdas of the form auto x .. . for -ranged loop of the form-for auto i : v .. . .. . Finally in general is true that auto local-variables are for forwarding . Standard Wordings for Forwarding References .. . .. . The term forwarding references is mentioned in the draft standard N4527 http : open-std.org JTC1 SC22 WG21 docs papers 2015 n4527.pdf in the following places : .. . .. . 14.8.2.1 Deducing template arguments from a function-call temp.deduct.call Emphasis Mine : .. . .. . If P is a cv-qualified type the top level cv-qualifiers of P s type are ignored for type deduction . If P is a reference-type the type referred to by P is used for type deduction . A forwarding-reference is an rvalue-reference to a cv-unqualified template parameter . If P is a forwarding-reference and the argument is an lvalue the type lvalue reference to A is used in-place of A for type deduction . Example : .. . .. . .. . template class T int f T heisenreference .. . template class T int g const T .. . int i .. . int n1 f i calls f int int .. . int n2 f 0 calls f int int .. . int n3 g i error : would call g int const int which .. . would bind an rvalue-reference to an lvalue .. . .. . .. . end example .. . .. . 14.8.2.5 p10 Deducing template arguments from a type temp.deduct.type : .. . .. . Similarly if P has a form that contains T then each parameter type Pi of the respective parameter-typelist of P is compared with the corresponding parameter type Ai of the corresponding parameter-type-list of A . If P and A are function types that originated from deduction when taking the address of a function template 14.8.2.2 or when deducing template arguments from a function declaration 14.8.2.6 and Pi and Ai are parameters of the top-level parameter-type-list of P and A respectively Pi is adjusted if it is a forwarding-reference 14.8.2.1 and Ai is an lvalue reference in which case the type of Pi is changed to be the template parameter type i.e . T is changed to simply T . Note : As a result when Pi is T and Ai is X the adjusted Pi will be T causing T to be deduced as X . end note Example : .. . .. . .. . template class T void f T .. . template void f int 1 .. . template void f int 2 .. . void g int i .. . f i calls f int int i.e . 1 .. . f 0 calls f int int i.e . 2 .. . .. . .. . .. . end example If the parameter-declaration corresponding to Pi is a function-parameter pack then the type of its declaratorid is compared with each remaining parameter type in the parameter-type-list of A . Each comparison deduces template arguments for subsequent positions in the template parameter packs expanded by the function-parameter pack . During partial ordering 14.8.2.4 if Ai was originally a function-parameter pack : Comment : A citation for It is known that since C++11 a parameter of type T is called an rvalue-reference would be appreciated .

Your code contains lots of stuff irrelevant to your question 3 . These are completely irrelevant for your questions 4 . A code can be minimal and working for compiler . This http : ideone.com zXuA0K could be a good MCVE for your question and its 25 lines long . .. . Answer : So first off please use the forwarding-reference instead of universal-reference . It better represents what it is and what is it s intended use . The first thing to be aware of is that not every is a forwarding-reference . It can also be an rvalue-reference . In simple terms T is a forwarding-reference if and only if : .. . .. . T is a simple simple as shown next type so for instance vector int or vector T is not a forwarding-reference . and T is deduced . In your example Args is not deduced . That is because you explicitly specify the function template argument Args when you call it : .. . .. . .. . .. . Let s work with something simpler to better understand : .. . .. . Lets set up the scene : .. . .. . In the next 2 calls we have forwarding-reference : .. . .. . In the first T will be deduced as X and by collapsing rules : X becomes X therefore we have an lvalue reference . As you would expect . In the second T will be deduced as X and by collapsing rules X becomes X therefore we have an rvalue-reference . But when you call it like this : .. . .. . T is no longer deduced . You basically say let T be X . So if T is X then T is X and you have the error : p whose type is now X cannot bind to an lvalue . .. . .. . Holt also added : .. . .. . Also note that because of the declaration of sortFunc this would not work even if you did not specify the function template arguments explicitely . I tend to agree with him but I would need to investigate further to be sure of this . Comment : Also note that because of the declaration of sortFunc this would not work even if you did not specify the function template arguments explicitely . Comment : I think that I understood your answer but my next question is : there is a way to make my code forwarding referencable and so make Args type deduced Comment : @justHelloWorld at first glance I would say no at least not without some nasty ugly hacks . You need to specify Args for sortFunc . Maybe if you make memFunc the last parameter don t know if it s possible so that Args deduction happens first but then it would change the signature of memFunc . But you could add remove reference t to the signature of memFuc s parameters . As I ve said ugly ugly hacks . Comment : @justHelloWorld Maybe if you post that as a separate question but please keep it minimal someone will come up with a good solution .

Which one is right Comment : Funny thing identity T seems to work in both GCC and Clang demo http : melpon.org wandbox permlink r1YH40UcY8lwouQ4 being treated as a forwarding-reference Comment : That s probably because T is of the format prescribed for forwarding references . Comment : @Angew Yes but as a function-parameter not as a template argument in a template-id . Comment : I have a sneaking suspicion that identity T is rejected by Clang because it triggers an overriding check of the form is the function-parameter an rvalue-reference if so if it refers to anything other than a plain template parameter it s not a forwarding-reference . Since identity T and forwarding-reference T from your other question don t contain the rvalue-reference syntax at the top level in the function-parameter they fall through to further processing . This is just a shot in the dark I haven t looked at the code . .. . Answer : Consider this code : .. . .. . Both GCC and Clang reject it because 2 is a redefinition of 1 . If they re actually the same template we could expect 1 to behave in the exact same way as 2 meaning that identity T should act as a forwarding-reference . Following this logic we don t know which one is right but GCC is at least consistent . This is also consistent with a very similar example in the standard at 14.5.7p2 . We should also consider the way template argument deduction can work in this case . If identity were a class-template its form could be matched against the type of the function argument without looking at its definition allowing the compiler to deduce the template argument for T . However here we have an alias template T cannot be deduced to int or int or anything else unless identity T is replaced by T . Otherwise what are we matching against Once the replacement is done the function-parameter becomes a forwarding-reference . All of the above supports the idea of identity T and identity T being treated as equivalent to a forwarding-reference . However it seems that there s more to this that the immediate replacement of the alias template-id with the corresponding type-id . Paragraph 14.5.7p3 says : .. . .. . However if the template-id is dependent subsequent template argument substitution still applies to the template-id . Example : .. . .. . .. . template typename.. . using void t void .. . template typename T void t typename T : : foo f .. . f int error int does not have a nested type foo .. . .. . .. . end example .. . .. . This might not seem to have much to do with your example but it actually indicates that the initial form of the template-id is still taken into account in some cases independently of the substituted type-id . I guess this opens the possibility that identity T could actually not be treated as a forwarding-reference after all . This area seems to be underspecified in the standard . This shows in the number of open issues dealing with similar problems all in the same category in my opinion : in what cases should the initial form of the template-id be taken into account upon instantiation even though it s supposed to be replaced by the corresponding type-id immediately when encountered . See issues 1980 http : www.open-std.org jtc1 sc22 wg21 docs cwg active.html 1980 2021 http : www.open-std.org jtc1 sc22 wg21 docs cwg closed.html 2021 and 2025 http : www.open-std.org jtc1 sc22 wg21 docs cwg active.html 2025 . Even issues 1430 http : www.open-std.org jtc1 sc22 wg21 docs cwg active.html 1430 and 1554 http : www.open-std.org jtc1 sc22 wg21 docs cwg active.html 1554 could be seen as dealing with similar problems . In particular issue 1980 http : www.open-std.org jtc1 sc22 wg21 docs cwg active.html 1980 contains the following example : .. . .. . with the note : .. . .. . CWG felt that these two declarations should not be equivalent . CWG - the Core working group .. . .. . A similar line of reasoning could apply to your example making identity T not equivalent to a forwarding-reference . This could even have practical value as a straightforward way of avoiding the greediness of a forwarding-reference when all you want is an rvalue-reference to a deduced T . .. . .. . So I think you ve raised a very interesting problem . Your example may be worth adding as a note to issue 1980 http : www.open-std.org jtc1 sc22 wg21 docs cwg active.html 1980 to make sure this is taken into account when drafting the resolution . In my opinion the answer to your question is for now a resounding who knows . .. . .. . Update : In the comments to the other related question http : stackoverflow.com q 29867841 4326278 Piotr S . http : stackoverflow.com users 3953764 piotr-s pointed out issue 1700 http : www.open-std.org jtc1 sc22 wg21 docs cwg closed.html 1700 which was closed as not a defect . It refers to the very similar case described in that question and contains the following rationale : .. . .. . Because the types of the function parameters are the same regardless of whether written directly or via an alias template deduction must be handled the same way in both cases . I think it applies just as well to the cases discussed here and settles the issue for now : all these forms should be treated as equivalent to a forwarding-reference . It will be interesting to see if this is changed indirectly by the resolutions for the other open issues but they mostly deal with substitution failures rather than deduction by itself so I guess such an indirect effect is rather unlikely . .. . .. . All standard references are to the current working draft N4431 the second draft after final C++14 .

I think we can expect further additions in this area as the other issues are resolved in one way or another .

Answer : First of all template types cannot be deduced from default-arguments http : stackoverflow.com questions 9628974 why-cant-the-compiler-deduce-the-template-type-from-default-arguments .

This question http : stackoverflow.com questions 15181741 can-a-defaulted-template-type-be-universal-reference confirms that the reference does remain a Forwarding Reference in that case .

Answer : Why does a std : : thread object accept the function-parameter by forwarding-reference and then make a copy of the object with decay copy Wouldn t it be easier to just accept the function object by value It has to have a copy of the function object in a storage that it can guarantee lasts as long as the thread it is about to launch lasts . A function argument to construct std : : thread would not last that long as the line where std : : thread is created can end long before the created thread ends . So it must make a copy . If it took its argument by-value it would make a copy when the constructor was called then have to make another copy to the persistent-storage . By taking it by forwarding-reference it makes exactly one copy . Now this additional copy could be moved-to making the extra overhead one extra move . This is still extra overhead as not all constructs are cheap to move . In general why would one not template a function so as to take a function object by value Because that mandates an extra move . Can reference-ness not be imitated with reference wrappers which would be more explicit and also conveniently has a member operator to call the stored function In the case where you intend to store the function object taking by forwarding-reference saves a move and doesn t require much extra work on the part of the writer of the function-object taking code . If the caller passed in a reference wrapper the value stored would be the reference wrapper which has a different meaning .

They re all r-value refs and ref collapsing rules kick in sometimes . So there s no syntax because there s no such thing as universal references in the standard . Comment : @Mat Right but the reference collapsing rules belong to the design I am questioning : It s not like the reference collapsing rules were god-given and rvalue references had to be designed around them : Comment : Useful link T Doesn t Always Mean Rvalue Reference http : isocpp.org blog 2012 11 universal-references-in-c11-scott-meyers from Scott Meyers Comment : @KerrekSB not really the rules had to be changed to allow T to deduce T as a reference-type it didn t just emerge . Comment : X x misses the template arguments . The code should compile when using X int x . .. . Answer : A universal-reference such as T can deduce T to be an object-type or a reference-type .. . .. . In your example it can deduce T as int when passed an rvalue so the function-parameter is int or it can deduce T as int when passed an lvalue in which case the function-parameter is int because the reference collapsing rules say std : : add rvalue-reference int : : type is just int .. . .. . If T isn t deduced by the function-call as in your X : : baz example then it can t be deduced to int so the reference isn t a universal-reference . So IMHO there s really no need for new syntax it fits nicely into template argument deduction and reference collapsing rules with the small tweak that a template parameter can be deduced as a reference-type where-in C++03 a function template parameter of type T or T would always deduce T as an object-type . These semantics and this syntax were proposed right from the beginning when rvalue references and a tweak to the argument deduction rules were proposed as the solution to the forwarding problem see N1385 http : www.open-std.org jtc1 sc22 wg21 docs papers 2002 n1385.htm s7 . Using this syntax to provide perfect-forwarding was proposed in parallel with proposing rvalue references for the purposes of move-semantics : N1377 http : www.open-std.org jtc1 sc22 wg21 docs papers 2002 n1377.htm was in the same mailing as N1385 . I don t think an alternative syntax was ever seriously proposed . IMHO an alternative syntax would actually be more confusing anyway . If you had template typename T void bar T @ as the syntax for a universal-reference but the same semantics as we have today then when calling bar i the template parameter T could be deduced as int or int and the function-parameter would be of type int or int .. . neither of which is T @ whatever that type is . So you d have grammar in the language for a declarator T @ which is not a type that can ever exist because it actually always refers to some other type either int or int . At least with the syntax we ve got the type T is a real type and the reference collapsing rules are not specific to function-templates using universal references they re completely consistent with the rest of the type system outside of templates : .. . .. . Or equivalently : .. . .. . When T is an lvalue reference-type T is too . I don t think a new syntax is needed the rules really aren t that complicated or confusing . Comment : +1 Nicely explained . Scott contacted me prior to his using his invented term universal-reference and I expressed concern that this may actually cause more confusion than teaching what the standard actually says . Nevertheless Scott has an outstanding track record of being an excellent teacher of C++ . Maybe use of his term will help people learn . Or maybe it will just cause confusion . I honestly don t know . In any event Jonathan s explanation of why things are the way they are and references to papers is spot on . Comment : @HowardHinnant same here I had been planning to write a piece for the ACCU journal Overload explaining it in terms of the typedef and add rvalue-reference examples above but Scott published first . I had exactly the same reservations when reviewing his piece for Overload but decided that because he s a far better teacher than I am with a far wider readership I d trust him to do a better job of explaining it to the world . I now use the term universal references in public but I still think in terms of deduction and ref-collapsing . Comment : Hmm just noting that Daveed answered to my mild rage on cpp-next.com http : cpp-next.com archive 2009 12 onward-forward comment-page-1 comment-270 by saying I and others voiced my preference for not trying to fit everything under the rvalue-reference type and instead introduce forwarding-specific notation and There were from the start people e.g . colleagues and I who thought the merging of moving and forwarding was a terrible idea and we sketched out other ways but also My bad for not putting in the energy to push those sketches forward as a competing proposal .

Tuples are ordered lexicographically meaning that the sequences are ordered the same as their first differing elements . For example 1 2 x 1 2 y returns the same as x y . It s worth noting that SQL-92 and mysql oracle postresql implements this correctly . The standard uses row value constructor to denote what I m calling a tuple .

Answer : SQLite doesn t support tuple comparisons . But a row constructor is a kind of shorthand . You can get the same result with a more complicated WHERE clause . I ve omitted the LIMIT 1 clause to make it easier to see that both queries return the same set . On platforms that support row constructors that is .

In oracle also output is one record as he mentioned . Comment : Yes this query isn t correct . According to the SQL standard a b 1 4 is equivalent to a 1 AND b 4 . This accounts for the IN predicate and subselects just as well . Your predicate is equivalent to 1 a OR 1 b AND 4 a OR 4 b Comment : @TimSchmelter You are correct It s giving 2 records .

Answer : If you are using T-SQL then an option that looks a bit like your hypothetical query is to use table literals like this : .. . .. . Here you create a table literal named v that contains the fields TaxID and AccountNumber . Now you can join the table literal on two fields to get the desired result .

You can read more about T-SQL support for table literals on this page http : msdn.microsoft.com en-us library dd776382 28SQL.100 29.aspx .

Answer : A crude way would be to concatenate the 2 values together. . .. . .. . e.g . However in e.g . SQL Server this would not be able to use an index .

Or you could do : Comment : Good point your JOIN-solution is the best so far but the query cannot be parameterised can it Comment : @UserControl - in TSQL as of SQL 2008 there is support for table-valued-parameters . So you can pass a table in as a parameter and join onto that instead . Or less desirably the older ways of doing it were to pass in CSV XML in and then extract the values out into a temp table to then join on .

The only things you need are the getter and the setter for the Collection List that obviously must be declared at class level not method level or it ll be destroyed once the method execution is over .

In this case even after populating the list it should also be noted that the display value of this column is catName category name of type String .

Comment : Added struts2-jquery tag because it has 31 followers while your other sj tags have 3 followers.. . Comment : Please add answer s if someone has . .. . Answer : In Struts 2 the HTML drop down list can be rendered via s : select tag . To auto select a default-value for a drop down list just declared a value attribute in the tag and set the default-value accordingly . Example : .. . .. . A Java list to generate the select options for the drop down box . tag to render the HTML drop down box . The value defaultSearchEngine will call the corresponds Action class getDefaultSearchEngine method to return a default search-engine value . Many Actions share common concerns . Some Actions need input validated . Other Actions may need a file-upload to be pre-processed . Another Action might need protection from a double submit . Many Actions need drop-down lists http : www.mkyong.com struts2 struts-2-sselect-drop-down-box-example and other controls pre-populated before the page displays .

Comment : But when I remove token tag the problem stil exists . Comment : Move the div out of the form unknown content could be returned after the action execution . Comment : As I wrote above jQuery submit works fine and it fills this div properly . The problem is that something override default onclick event for the last default struts 2 submit and there is no submition no action created . Comment : Assign id to the last submit to make sure that nothing override it except might be you . Comment : This also didn t help.. .

I have a strut2 jquery grid along with a form on my webapp s landing s page . The grid is populated and made visible via ajax call when the form is submitted . It was functioning incorrectly at first since the grid would make an ajax call initially when the user hits the landing page making unnecessary requests . I fixed this with hiddengrid true and now the grid does not make any initial requests when the landing page is first hit which is good . But now my ajax call does not work at all when I submit the form . It does not even reach the action . Setting that above attribute to true has something to do with it but I am not sure how to fix the issue . TL DR Struts2 jQuery grid no longer hits url after setting hiddengrid true . Setting the attribute to false fixes the issue but then the grid makes an initial unnecessary request .

The list in the grid however displays nothing in edit mode when the edit link is clicked . I cannot find relative examples that may demonstrate this kind of thing .

In this case even after populating the list it should also be noted that the display value of this column is catName category name of type String .

Answer : Regarding to the documentation connected with gridColumn and editoptions property : .. . .. . dataUrl .. . .. . This option is valid only for elements of type select - i.e . edittype : select and should be the URL to get the AJAX data for the select element .

Answer : As the author of django-rest-framework I ve got an obvious bias but my hopefully-fairly-objective opinion on this is something like : .. . .. . TastyPie .. . .. . As Torsten noted you re not going to go far wrong with something written by the same peeps as the awesome django-haystack http : haystacksearch.org . From what I ve seen on their mailing list Daniel Lindsey et al are super-helpful and Tastypie is stable comprehensive and well documented .. . Excels in giving you a sensible set of default behaviour and making building an API with that style incredibly easy . Django REST framework .. . .. . Gives you HTML browse-able self-describing APIs . EG see the tutorial API http : restframework.herokuapp.com . Being able to navigate and interact with the API directly in the browser is a big usability win . Tries to stay close to Django idioms throughout - built on top of Django s class based views etc.. . Whereas TastyPie came along before Django s CBVs existed so uses it s own class-based views implementation .. . I d like to think that the underlying architecture is pretty nicely built decoupled etc.. . In any case both are good . I would probably characterise Tastypie as giving you a sensible set of defaults out of the box and REST framework as being very nicely decoupled and flexible . If you re planning on investing a lot of time in the API I d def recommend browsing through the docs codebase of each and trying to get a feel for which suits you more . Obviously there s also the Why TastyPie https : github.com toastdriven django-tastypie section in it s README and the REST framework 2 announcement http : django-rest-framework.org topics rest-framework-2-announcement.html . See also Daniel Greenfeld s blog post on Choosing an API framework for Django http : pydanny.com choosing-an-api-framework-for-django.html from May 2012 Worth noting that this was still a few months before the big REST framework 2.0 release .

Like : This is my urls.py file which contains a list of URLs and if any of the URL is hit it directly calls to view function present in views.py file and rest I do the particular operation in that function like connecting to MySQL database executing SQL queries and returning JSON response to the front end . Is this a good approach to making API calls If not Please guide me . Any advice or help will be appreciated . Comment : you need to make the changes to your models.py and run . manage.py makemigrations and . manage.py migrate and your database will-change according to the changes in you models . .. . Answer : Django REST Framework is designed to work with Django Framework . And Django ORM is an integral part of Django Framework . Granted that it is possible to use Django and DRF without using ORM but you will be basically fighting against the framework instead of using the framework to help you . So you have three basic approaches . 1 . If all you want is to develop RESTful APIs in python and pull data from an existing MySQL database or you don t have a database but you want something simple . You can use something framework agnostic like restless http : restless.readthedocs.io en latest or even hug https : github.com timothycrosley hug .. . .. . 2 . If you do not have any existing data and you want a full blown web framework you should consider using Django I make my living as a Django dev there is no shame in this and embrace the ORM . In this case DRF is one of the better REST frameworks for Django at the moment . 3 . If you have existing database and are somehow stuck with using Django there are some ways to use Django ORM with existing data you should look at Django docs on the topic https : docs.djangoproject.com en 1.9 howto legacy-databases", "Question : null .. . Answer : We are building a Django Web Application using Django Rest Framework and AngularJS . We would like to add feature flipping feature flags to our framework .

Answer : If you notice that a token is like a session cookie then you could stick to the default lifetime of session-cookies in Django : https : docs.djangoproject.com en 1.4 ref settings session-cookie-age .

Comment : Wouldn t you want to create a new token in ObtainExpiringAuthToken if it s expired though rather than just update the timestamp for the old one Comment : Creating a new token makes sense .

There must be done manually through jquery unless I m missing something I see is this : you have to use preventDefault for the submit event of the form to create a post product or whatever and use the function post to send the relevant parameters which I think is ridiculous for a framework that claims to be based on the best ideas from other frameworks . Please tell me if I m wrong I like FUELPHP and I m thinking about choosing it as PHP framework but I want to be clear about this . Comment : Some do not want to prevent default handling of events and since that is written into JavaScript the developers at jQuery decided not to re-invent the wheel so to speak . How do you think it should work Comment : You might be getting a bit confused here . FuelPHP is a PHP framework it runs on the server and has nothing to do with JavaScript other than serving it to the browser . I don t know of any framework in the PHP world that mimics RoR s ajaxy form handling . .. .

When I access my simple controller .. . .. . I get a 404 error . fuel is the directory of this freshly installed fuelPHP on my localhost .

Comment : Have you got .htaccess set up If so can you post the code Comment : @BenSwinburne This is a fresh install . On fuel there s no .htaccess fuel fuel has .htaccess and it only contains deny all in it . But really the default controller .. . welcome.php was able to be access without any problems here . Comment : There should be one in public as part of the default install but depending on your apache php configuration you may need to tweak it . The reason the welcome controller works is because the route loads the correct page . It s the .htaccess which send the hello bit off to index.php Comment : What about http : localhost fuel public index.php hello index specifying the action name too . Comment : @BenSwinburne I will add the .htaccess on the public folder . What should I add here .. . Answer : You are making it very complicated for yourself by installing FuelPHP like this . It has been designed in such a way that the public folder is your webservers document root which means all fuel stuff is outside your document root and the .htaccess is directly inside your document root . By not only installing it entirely inside your document root but also in a subfolder of that document root you need to modify your rewrite rules . Start by adding .. . .. . to the one in public and see if that helps . Also this .htaccess is made for standard apache type installations . If you run anything else you might need a different .htaccess . If you use fcgi for example get the .htaccess from the 1.4 develop repo it s more fault tolerant towards your webserver type . Final remark : you should not use localhost as hostname . It s an illegal name in a lot of RFC s one of them being the one that documents the use of cookies . You ll have all kinds of session issues with some browser versions if you use localhost . Instead setup virtual-hosts a better solution then subfolders anyway and use a hostname like mymachine.local .", "Question : I m new to FuelPHP and web development in general .

If you want your REST controller to break the flow at some other point than when the requested method returns something use this code .

For more information on the send method check out the FuelPHP documentation for the response class . http : fuelphp.com docs classes response.html Comment : Yes that is equally bad practice .

Thanks . .. . Answer : ActionBarSherlock gives your application an action bar regardless of what version of the android API your app is being run on . Action Bar Compatibility gives you the action bar only if the device that you re running on is API level 3.0 or above . Note that if the device you re running on isn t 3.0 or above ActionBarSherlock is going to use it s own custom implementation of the action bar not a native one . --EDIT-- .. . .. . It appears things have changed and there is actually no difference between ActionBarSherlock and the Action Bar Compatibility anymore . Please read the comments below for details . --EDIT-- .. . .. . After having used both now I can say that I actually prefer ActionBarSherlock to Action Bar Compatibility . ActionBarSherlock is really easy and nice to use . --EDIT-- As LOG TAG mentioned there is now support for the action bar in the Android Support Library . I haven t had a chance to use it yet but I would imagine that s the best one to use . Comment : @Anidamo Thanks for the heads up . I might be going insane but I could swear that at one point the version in the android compatibility pack didn t give you one if your pre-3.0 . I ve modified my answer . Comment : Also the answer is totally wrong - the purpose of the compatibility example is to support pre-3.0 devices . Comment : Google released a new backward-compatible Action Bar implementation called ActionBarCompat that s part of the Support Library r18 . The ActionBarCompat APIs let you build the essential Action Bar design pattern into your app with broad compatibility back to Android 2.1 .

Thanks . .. . Answer : Actionbar Sherlock is far more advanced and far more ambitious than the simple Actionbar compatibility project . The Action bar compatibility can be considered a sample or a good starting point if you only want to smack an Action Bar on top of your app . ActionBarSherlock builds on the compatibility library and gives you like the action bar compatibility sample an Action Bar on pre-3.0 devices . In addition it has extra features not present in the ActionBar Compat code . This includes features like but not limited to .. . .. . setNavigationMode for Tabs and spinners in the action bar .. . Dialog Fragments .. . Contextual Action Bar CAB a menu that takes over the action bar used for example for multi-select http : developer.android.com design-patterns new-4-0.html This is a ICS feature For this an implementation of the ActionMode class introduced in API level 11 had to be introduced into the ActionbarSherlock library .. . Fragment and FragmentActivity implementations - because fragments can implement the onCreateOptions menu we need to make sure that the SupportMenuInflater is used . Two themes not very unlike Holo.Dark and Holo.Light Theme.Sherlock Theme.Sherlock.Light .. . The ICS feature split action bar .. . .. . The only downside I see in using ActionbarSherlock is that you lock yourself in to that library . If for some reason it will die out in the near future you ll have to maintain it youself for example if no Jellybean implementation comes along . This is a hassle not a huge problem since all your fragments extends SherlockFragemnt and all your Activities . SherlockActivity . Comment : Am I missing something It seems that multi-select is NOT support in ABS Comment : Sorry for the delay . Multi select is not by itself supported by ABS . But you can implement Multiselect by using the ABS ActionMode as ABS has its own implementations of the ActionMode classes . When going into multi-select mode You would set the ListView s choice mode to CHOICE MODE MULTIPLE and invoke ActionMode by calling getSherlockActivity .startActionMode callback", "Question : What is the difference between ActionBarSherlock http : actionbarsherlock.com and Action Bar Compatibility http : developer.android.com resources samples ActionBarCompat index.html .. . .. .

Thanks . .. . Answer : I strongly believe that you should use ActionBarCompat for all new projects that want to support older devices . It also might make sense to migrate existing projects . So read on to learn why you should migrate or use ActionBarCompat right away and how to migrate existing projects . Why you should prefer ActionBarCompat over ActionBarSherlock .. . .. . There are many reasons why you should prefer ActionbarCompat over ActionbarSherlock . 1 . First of all this project is by Google is part of the Support Library and thus likely will support new Action Bar related stuff at the same time Google releases them with stock Android . 2 . Another good reason is that it supports the Navigation Drawer pattern right out of the box while ActionBarSherlock does not . Thus if you want to add this drawer to an existing project app you should migrate . 3 . The last and Important is that the creator of ActionBarSherlock Jake Wharton announced on Google+ that further development of ActionBarSherlock has been stopped . ActionBarSherlock 4.4 is the last release and might get bug fixes but there won t be any new features : So if new functionality is included in actionbar you may not keep up to it with actionbarsherlock .", "Question : What is the difference between ActionBarSherlock http : actionbarsherlock.com and Action Bar Compatibility http : developer.android.com resources samples ActionBarCompat index.html .. . .. .

If you re using a third-party solution such as ActionBarSherlock there are a few reasons to consider upgrading : .. . .. . Can be kept updated as the Action Bar API evolves . Integrated Ancestral Navigation support . Use of framework Menu and MenuItem classes . Continue to use the Support Library s Fragment class . Integrated support for ActionBarDrawerToggle for use with DrawerLayout . Backport of PopupMenu . .. . ActionBarSherlock is a solid and well-tested library which has served developers very well for a long time . If you are already using it and do not currently require any of the above then there is no need to migrate .", "Question : In trying to follow the Android Design Guidelines I m running into a small quandary .

UPDATE : as @rudy-s said with newest android-support-library api 18 I saw they already have built-in support for actionbar called ActionBarCompat class .

Comment : @AnkushGupta thanks for the info +1", "Question : Android action bar compat http : developer.android.com resources samples ActionBarCompat index.html .. . Is it possible On older devices pre 3.0 the items that don t fit the action bar are only shown when the menu key is pressed I want these items to be grouped in the actionbar s overflow menu . Comment : From the ABS changelog CHANGELOG.md : 27 : Fix : Remove .ForceOverflow themes . These never should have been included . .. . Answer : The action overflow menu is only available when there is no hard menu button available on the device . I found this stated in the Framework Topics under User Interface Action Bar check out the 3rd bullet here http : developer.android.com guide topics ui actionbar.html . There is an action bar library written by Jake Wharton http : stackoverflow.com users 132047 jake-wharton called ActionBarSherlock . Perhaps this is able to supply you with an action overflow menu style even when on older devices which include a hard menu button however I have not looked into this . Edit : ActionBarSherlock 4.0 currently a release candidate has functionality built-in to force action overflow . If you want to extend the ActionBarCompat example yourself you could take a look on github to get an idea how Jake implemented it . I would suggest just looking into using his library all together as it is very well done . If you choose to use Jake s library look into setting up the Activity theme as @style Theme.Sherlock.ForceOverflow to force the overflow menu on older devices . Edit2 : Using ForceOverflow theme causes issues example 1 https : github.com JakeWharton ActionBarSherlock issues 568 on devices with hardware menu button . Thus Jake Wharton is going to remove ForceOverflow in the future versions . Comment : You didn t read the question very carefully . He s using an official android action bar library to get the backwards and forwards compatibility . He wants to force the overflow option below Android 4.0 not turn his old menu into a functioning menu on ICS . Comment : @EricNovins ABS library offers what he is looking for . If he chooses not to use the library if offers a direction for him to extend ActionBarCompat in his own way . Comment : I wouldn t ever suggest to ditch the library completely . That s a ton of recoding for one function . Not a quality answer IMO Comment : But how could Google use action overflow on let s say Google+ I m using a Nexus S that has the hard menu button so the overflow shouldn t be there...Anyway I see it on almost all stock gapps Comment : @Shine Even though you have the hard menu button the developer can force the overflow button to appear . This will just give a consistent UI across all devices even if they are pre-ICS .", "Question : In trying to follow the Android Design Guidelines I m running into a small quandary .

Answer : Well @Jake implementation goes way further than what the Actionbar compat to be more precise Actionbar Compat is just a basic example on how can you support all aplication with a pseudo-actionbar for releases prior from Honeycomb API 13 . Although their target is the same cross compatible actionbar they have diferent approach . ActionbarCompat Aproach .. . .. . This implementation make no use of the Compatibility Android support library instead it create a base-class called ActionBarActivity http : developer.android.com resources samples ActionBarCompat src com example android actionbarcompat ActionBarActivity.html create a single instance of a Helper http : developer.android.com resources samples ActionBarCompat src com example android actionbarcompat ActionBarHelper.html this helper act as factory itself that returns diferent implementation for the three segment of APIS it returns .. . .. .

ActionBarHelperICS http : developer.android.com resources samples ActionBarCompat src com example android actionbarcompat ActionBarHelperICS.html : for ICS base devices . The most interesting part is in the ActionbarBaseHelper http : developer.android.com resources samples ActionBarCompat src com example android actionbarcompat ActionBarHelperBase.html because it has the most important code I suggest you understand this class and you will get the whole example . Action Bar Sherlock .. . .. . Well this is tricky firstable because I m not the author maybe Jake can explained further this but I ll give it a try . Just as the compat Sherlock make diferent implementation but one is for Compat and the other is Native . It force you to extends either from SherlockActivity or from SherlockFragmentActivity because this two base classes have the method for dispatching the ActionBar .

Answer : I was facing the same issue . It was solved when I found this link http : www.miximum.fr tutos 849-porting-the-contextual-anction-mode-for-pre-honeycomb-android-apps . Basically you have to create a callback class that implements ActionMode.Callback . In this class you inflate the Action Bar with your contextual Action Bar . At each selection or long-click you start the callback using the startActionMode method . See the link for an working code .. . .. .

Answer : You can modify onLongClick in ActionMenuItemView https : github.com JakeWharton ActionBarSherlock blob master actionbarsherlock src com actionbarsherlock internal view menu ActionMenuItemView.java Class to stop Toasting on long-click . but be careful It s only working on devices with API less than 11 because sherlockactionbar library checking your device API level by Build.VERSION.SDK INT and if you have newer device it just use default system actionbar which you re not modifying .", "Question : I have created a project with help of Action Bar Sherlock .

Comment : @gexicide : But as noted in the answer it actually works out that with at least one widely-used implementation it s actually faster to do some string operations with sprintf and such than with the functions that seem like they should be faster in some cases by a fair margin .

Answer : strncpy combats buffer-overflow by requiring you to put a length in it . strcpy depends on a trailing 0 which may not always occur . Secondly why you chose to only copy 5 characters on 7 character string is beyond me but it s producing expected behavior . It s only copying over the first n characters where n is the third argument . The n functions are all used as defensive coding against buffer overflows . Please use them in lieu of older functions such as strcpy .

Comment : I am not sure why this is getting lots of up votes - strncpy was never intended as a safer alternative to strcpy and in fact isn t any safer as it doesn t zero termninate the string . It also has different functionality in that it pads up the supplied length with NUL chars . As caf says in his reply - it is for overwriting strings in a fixed size array .

This answer addresses the former not the latter . Comment : The fact remains that strncpy is not a safer version of strcpy . Comment : @Sinan : I never said it was safer . It s defensive .

Comment : @Steve : right -- There ain t no such thing as a free lunch although doing two copies is very far from a free lunch in the first place : - Comment : Regarding your edit as an interviewer my very next question would be : Why would you not rely on memmove and instead trade a one-liner against an unmaintainable pointer handling mess .. . Answer : Note : Here b is the address of the source string and a is the address of the destination . With a b you wouldn t necessarily have an overlap . If .. . .. . then you have an overlap . However besides detecting overlap for the sake of interview a b should do fine for strcpy . The idea is this : .. . .. . If b is placed further in the memory b a then you can normally copy b into a . Parts of b will be overwritten but you are already past that part . If a is placed further in the memory a b it means that possibly by writing on the first location of a you have already overwritten a location in b with a higher index . In such a case you should copy in the opposite direction . So instead of copy from index 0 to strlen b -1 you should copy from strlen b -1 to 0 . If you are confused how that helps draw two overlapping arrays on paper and try to copy once from the beginning of the array and once from the end . Try this with the overlapping arrays both in cases a b and a b . Note if a b you don t need to actually copy anything and you can just return . Edit : I am not sure but reading the other solutions it seems like this answer may not be completely portable . Beware of that . Comment : if a b you could even just return : - strcpy takes pointers-to-non-volatile so there s no requirement to actually touch the memory .

Answer : I was asked this in a recent interview . We don t have to detect overlap . We can write strcpy in such a way that overlapping addresses are taken care of . The key is to copy from the end of source string instead of from the start . Here is a quick code . EDIT : This only works when a b . For a b copy from the start .

Like memcpy you should copy from beginning or the end based on if the destination to copy has lower or higher address than the source respectively . Comment : +1 good point .

Efficiency is of utmost importance . There ist the strcpy function which can achieve this but it does not return how many characters are actually copied . Of course I could find this out by simply calling strlen afterwards to detect the length of the copied string but this would mean traversing the characters in the string again a second time although strcpy has to track how many characters it copies anyway . For performance reasons I do not want such a second traversal . I know that writing an own strcpy with a simple char-by-char copy is easy but I thought that the standard-library might apply magic which makes strcpy faster than a naive char-by-char implementation . So what is the best method to strcpy and receive the number of copied characters without traversing the string again Comment : strcpy is not complicated you could rite your own .. . Comment : Don t see how just using strcpy . If you know the length of string being copied then use that as strcpy will always copy all characters from source string including null so it really copies strlen src +1 chars .

Answer : Even without using relational pointer comparisons memmove or equivalent it is possible to code a version of strcpy which will be performed as an strlen and memcpy in the non-overlapping case and as a top-down copy in the overlapping case . The key is to exploit the fact that if the first byte of the destination is read and then replaced with zero calling strlen on the source and adding to the source pointer the value that was returned will yield a legitimate pointer which will equal the start of the destination in the troublesome overlap case . If the source and destination are different objects the source plus strlen pointer may be safely computed and observed to be unequal to the destination . In the event that adding the string-length to the source pointer yields the destination pointer replacing the zero byte with the earlier-read value and calling strlen on the destination will allow code to determine the ending address of the source and destination strings . Further the length of the source string will indicate the distance between the pointers . If this value is large probably greater than 16 or so code may efficiently subdivide the move operation into a top-down sequence of memcpy operations . Otherwise the string may be copied with a top-down loop of single-byte copy operations or with a sequence of memcpy to source to buffer memcpy buffer to destination operations if the per-byte cost of a large memcpy is less than half that of an individual-character-copy loop using a 256-byte buffer may be a useful optimization .", "Question : Background : I have a small routine that mimics fgets character 2 fp except it takes a character from a string instead of a stream . newBuff is dynamically allocated string passed as a parameter and character is declared as char character 2 .

Problem : Valgrind does warns me about this activity Source and destination overlap in strcpy 0x419b818 0x419b819 . Should I worry about this warning .. . Answer : The behavior of strcpy is officially undefined if source and destination overlap . From the manpage for memcpy comes a suggestion : .. . .. .

Answer : If these two strings overlap then while copying you ll run over the original a or b pointers . Assuming that strcpy a b roughly means a - b i.e . the first parameter is the destination of the copy then you only check whether the copy pointer reaches b s position . You only need to save the b original position and while copying check you haven t reached it . Also don t write the trailing zero if you have reached that position . This algorithm just stops copying . Maybe you want to do something else such as marking the error condition or add an end-of-the string mark to the previous position though failing silently as the algorithm does at the moment isn t the best option .

Answer : Are there any cases where strcpy can t be replaced by strcat after setting the initial character of the target to 0 I don t think so . Does that mean you should always use strcat when strcpy would do the job Absolutely not . strcpy makes no assumptions about the initial contents of the target array . strcat requires the target to contain a terminating 0 null character -- and if it s not in the initial position it will scan for it to and possibly beyond the end of the array .

I mean it totally broke me in and made higher level languages MUCH more fun : .. . Answer : The strncpy function is the safer one : you have to pass the maximum length the destination buffer can accept . Otherwise it could happen that the source string is not correctly 0 terminated in which case the strcpy function could write more characters to destination corrupting anything which is in the memory after the destination buffer . This is the buffer-overrun problem used in many exploits .. . .. . Also for POSIX API functions like read which does not put the terminating 0 in the buffer but returns the number of bytes read you will either manually put the 0 or copy it using strncpy . In your example code index is actually not an index but a count - it tells how many characters at most to copy from source to destination . If there is no null byte among the first n bytes of source the string placed in destination will not be null-terminated", "Question : Some people seem to think that C s strcpy function is bad or evil .

Suppose s1 is a pointer to a string maintained internally by the memory-management system -- maybe the last time malloc was called . .. . Answer : The reason why people use strncpy not strcpy is because strings are not always null-terminated and it s very easy to overflow the buffer the space you have allocated for the string with strcpy and overwrite some unrelated bit of memory . With strcpy this can happen with strncpy this will never happen . That is why strcpy is considered unsafe . Evil might be a little strong . Comment : strncpy is also dangerous because it does NOT guarantee that the destination string is 0-erminated Better use strncpy s though I m not sure whether these functions are MS specific . Comment : strncpy only keeps you safe if you pass in the right length . If you re strncpying to a dst which is not the start of a buffer you still have to calculate the available space . This isn t fundamentally different from using strlen to check your strcpy will fit : it s still subtraction . But less code . Comment : @jn - strncpy s is a proposed addition to ISO ANSI C ISO IEC TR 24731-1 except that MS doesn t implement it quite this way . Comment : strings are not always null-terminated is a false statement . A string by definition is a sequence of characters that s null-terminated .
