[WP-o-Matic](http://wordpress.org/extend/plugins/wp-o-matic/) is a wordpress plugin to auto post based on some configured feeds, it read feeds everything time interval i setup, its working on my blog, my blog is on shared windows web hosting, i want to know how it auto work like that, and because i am on a shared hosting, so sure i didn't setup any windows services on the server, so its just keep working just after activating, seams strange idea for me. 

How WP-o-Matic works and how to do the same using ASP.Net? Cron job equivalent in .NET?

I've got a database table with one huge column: .  I'd rather lazy load that one column so I'm not querying all that when I get a list of all my images. I know I can put the data into its own column and entity like this:  But, do I have to?

Can I lazy load scalar properties with the ADO.Net Entity Framework?

: Visual Studio 2008 SP1 with Resharper 4.1, .NET 3.5 I have a class with a static method, `GetProperty<T>` that returns a property value lazily. ``` private static T GetProperty<T>(T backingField, Func<T> factory) where T : class { if (backingField == null) backingField = factory(); return backingField; } ``` But when I use above method to return a property, I am getting two warnings that says that private backing fields are not assigned. But they are assigned later on only when they are needed.  Is this warning ? -- Or -- Is my appoach to loading a property flawed?

Is my approach to lazy loading flawed?

I have 2 tables, ticket and ticket_custom. Here are how the tables are set up. I have a web interface where I can change the state (value in the table ticket_custom) The web interface adds a new entry instead of updating the original entry. ``` ticket name value 1 state Ready for Final Verification 2 state Ready for Final Verification 1 state Verified ``` The last row is added So I need to modify the queries. ``` SELECT p.value AS __color__, id AS ticket, summary, component, version, c.value AS state, milestone, t.type AS type, owner, status, time AS created, changetime AS _changetime, description AS _description, reporter AS _reporter FROM ticket t, ticket_custom c LEFT JOIN enum p ON p.name = t.priority AND p.type = 'priority' AND id = c.ticket WHERE status <> 'closed' AND id = c.ticket ORDER BY CAST(p.value AS int), milestone, t.type, time, c.ticket ``` The query now returns both entries. I tried to add a nested select in the where clause. ``` SELECT g.ticket FROM ticket_custom g WHERE g.ticket = id ORDER BY g.ticket DESC LIMIT 1 ``` So - ``` SELECT p.value AS __color__, id AS ticket, summary, component, version, c.value AS state, milestone, t.type AS type, owner, status, time AS created, changetime AS _changetime, description AS _description, reporter AS _reporter FROM ticket t, ticket_custom c LEFT JOIN enum p ON p.name = t.priority AND p.type = 'priority' AND id = c.ticket WHERE status <> 'closed' AND id = c.ticket and ( SELECT g.ticket FROM ticket_custom g WHERE g.ticket = id ORDER BY g.ticket DESC LIMIT 1 ) ORDER BY CAST(p.value AS int), milestone, t.type, time, c.ticket ``` Clearly I'm doing something wrong.

I'm doing a job for a guy with a site online. It's an alien site to me, and I'm slowly working through the strange code. I have MAMP locally and my [http://localhost/](http://localhost/) has many client folders coming off from that. Inside this code there is a lot of $_SERVER['document_root'] commands and references like  which are just getting lost on my local PHP dev area. How can I easily set the document_root reference to what it should be (just locally though, don't really want to mess with the site files, as I'll need to upload them again and don't want to break live site! And is there a way of indirect setting where PHP thinks the root of the site is so the image's src references "/images/..." will show up properly... My local PHP dev URL for this site is: [http://localhost:8888/_CLIENTS/clientsite/www/](http://localhost:8888/_CLIENTS/clientsite/www/) ...but in the code the '/' at the beginning of '/images/...' is referencing [http://localhost:8888/](http://localhost:8888/) ?? Thank you.

I'm used to git, where you can run gitk and get something like the following:  Here you can see that there are a couple of changes that need pushing to the remote branch. Alternatively, I can use `git log --decorate` and the output would be: ``` b8c2926... (refs/heads/next) Update instructions 6d9f914... Add a first go at generic x compiling 49a6dac... (refs/remotes/github/next) Ignore temp files ``` Is there anything like this with Mercurial?

I'm not sure exactly what went wrong here, but ReSharper 4.5 RTM seems to have stolen my Visual Studio colour theme. I normally use [Fredrik Kalseth's wicked theme](http://www.frickinsweet.com/tools/Theme.mvc.aspx), and I've been using ReSharper since version 2.0. Never before has this happened - not even while using the 4.5 Beta. My scheme remained intact without detrimental interference - well, actually ReSharper did its normal highlighting which was actually quite complimentary! But this time, when building my new machine, the outcome looks like this:  Yes I know that ReShaper colours can be configured under Tools->Font and Colors, but firstly, I don't want to have to do that, and secondly, I want to understand why this has happened only now, and never before. When I uninstall ReSharper, the colours go back to normal. I have tried removing the theme and resharper and reinstalling in different orders to no avail. I apply the theme with a code file open, and see a brief flash of the correct colours how they used to look, and then ReSharper takes over. I've tried [Ryan and Joel's AWESOME theme generator](http://www.frickinsweet.com/tools/Theme.mvc.aspx), but I see the same brief flash of the correct colours being applied after importing, and then the crappy colours overlay themselves again. I say they are crappy only in the context of a dark theme, on a light theme they look just fine. I just want to know how to have my cake and eat it like it's been all this time. I must stress, that the theme and resharper have been working hand in hand perfectly together all the time I've used it (6 months at least), it's only happened on my new machine - my old machine looks and works fine. Oh - and I have a fully licensed version of ReSharper - not a trial. Any help is much appreciated.

I am trying to create a general method for disposing an object that implements [IDisposable](http://msdn.microsoft.com/en-us/library/system.idisposable(loband).aspx), called `DisposeObject()` To make sure I am disposing an object pointed by original reference, I am trying to pass an object by reference. But I am getting a compilation error that says > The 'ref' argument type doesn't match parameter type In the below (simplified) code, both `_Baz` and `_Bar` implement [IDisposable](http://msdn.microsoft.com/en-us/library/system.idisposable(loband).aspx).  So the questions are, 1. Why am I getting this error? 2. Is there a way to get around it? From provided answers so far, as long as I do not set an IDisposable argument to null, I can simply pass an object by value without using `ref`. I am now having another trouble whether to set disposable objects to `null` or not within `DisposeObject` method. Here is the full source for completeness: ``` public class Foo : IDisposable { private Bar _Bar; private Baz _Baz; private bool _IsDisposed; ~Foo() { Dispose(false); } public void Dispose(bool disposing) { if (!_IsDisposed) { if (disposing) { DisposeObject(ref _Baz); DisposeObject(ref _Bar); } } _IsDisposed = true; } private void DisposeObject(ref IDisposable obj) { try { if (obj == null) return; obj.Dispose(); obj = null; } catch (ObjectDisposedException) { /* Already Disposed... */ } } public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } } public class Bar : IDisposable { public void Dispose() {} } public class Baz : IDisposable { public void Dispose() {} } ``` I removed the code that sets argument to null (`obj = null;`) within `DisposeObject` So the final code became. ``` public void Dispose(bool disposing) { if (!_IsDisposed) { if (disposing) { DisposeObject(_Baz); DisposeObject(_Bar); } } _IsDisposed = true; } private void DisposeObject(IDisposable obj) { try { if (obj == null) return; obj.Dispose(); } catch (ObjectDisposedException) { /* Already Disposed... */ } } ```

Passing an IDisposable object by reference causes an error?

I am hoping that someone (or some people) could help us with a problem that we have wrangled with for a few days. How to organize our business objects given the attached diagram? We are looking for any assistance (ideas about where to or how to search for the design pattern(s)/object model(s) we could use in order to solve this problem. Our situation is slightly more complex, but we have tried to simplify it best we could for the purposes of asking this question. Some Details: Some companies have product lines and some don't. Each company has a list of contacts. If a company has at least one product line, some of those company contacts are ALSO associated with at least one product line. A few of the contacts are references (business/personal) for other contacts. Each company and each contact can have zero or more addresses. Thank you for any assistance finding a more appropriate solution (My assumption is that we will need to use multiple models/patterns).  [Larger view of diagram (flickr.com)](http://www.flickr.com/photos/9844492@N08/3480423086/sizes/o/) ** (from the diagram) Our company has employees/internal application users who are included with contacts because they can also be references, etc.

I'm rather new to working with multiple threads in a database (most of my career has been spent on the frontend). Today I tried testing out a simple php app I wrote to store values in a mysql db using ISAM tables emulating transactions using Table Locking. I just wrote a blog post on the procedure Here: [Testing With JMeter](http://leeand00.tiddlyspot.com/#[[Testing%20With%20JMeter]]) From my results my simple php app appears to keep the transactional integrity intact (as seen from the data in my csv files being the same as the data I re-extracted from the database): # CSV Files:   # Query Of Data for Both Users After JMeter Test Run:   Am I right in my assumption that the transactional data integrity is intact?

How might I create a brush that paints a regular, repeated grid of 1-unit thick lines spaced evenly in both the horizontal and vertical axes? Imagine graph paper, if you will. Ideally the solution would allow control over the brushes used for the lines and the background (the regions within the squares). In this way the background could be transparent, so that the grid could serve as an overlay. Here is an image that shows the result of Tom's answer below:  For this example a grid was used to composite three layers to show that the grid is truly transparent.

I'm building a UITableView programmatically without NIB files here. I'm doing something silly however, as my navigationBar shows up fine, as does my UITableView. However, the UITableView is not properly fitting onto the screen. You'll see roughly 20 pixels separating the UINavigationBar and the UITableView. I set my window's backgroundColor to black, as you can see in this screen shot:  Here's the code to reproduce the problem: ``` - (void)loadView { [super loadView]; // TableViews that wish to utilize tableView footers/headers should override this method. UITableView *aTableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain]; aTableView.autoresizingMask = (UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight); aTableView.separatorStyle = UITableViewCellSeparatorStyleSingleLine; aTableView.delegate = self; aTableView.dataSource = dataSource; self.tableView = aTableView; [self.view addSubview:self.tableView]; [aTableView release]; // style navigation bar. //self.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque; } ```

I'm trying to figure out a simple drawing program in Flash and it's giving me trouble. The main drawing area is a MovieClip named drawZone. However, when displaying something, the author uses another MovieClip embedded in the drawZone Symbol named zone. The drawZone Symbol has 2 layers, a mask layer and a masked sublayer that contains the zone Symbol. 1. Why does the author do this instead of simply drawing everything in the drawZone MovieClip? 2. The only place the zone Symbol shows up is in the Movie Explorer. Where do I access it, and how would I add such an embedded Symbol to my own code? Here's a screenshot:

If I do ``` myPane.XAxis.Type = AxisType.Text; myPane.XAxis.Scale.TextLabels = array_of_string; ``` I get labels on the XAxis like this  And if I do ``` for (int i = 0; i < myCurve.Points.Count; i++) { PointPair pt = myCurve.Points[i]; // Create a text label from the Y data value TextObj text = new TextObj( pt.Y.ToString("f0"), pt.X, pt.Y + 0.1, CoordType.AxisXYScale, AlignH.Left, AlignV.Center); text.ZOrder = ZOrder.A_InFront; text.FontSpec.Angle = 0; myPane.GraphObjList.Add(text); } ``` I get labels on the curve, like this  But if I do both at the same time, labels on the curve disappear. Is there a way to combine both kind of labels?

I have a WPF application (.NET 3.0, VS2008) that displays data in a tab control. Custom colors are required on virtually all controls in this application : basically white foreground and green background. My problem is that when an XP theme (say Luna) is active, it is automatically applied to render controls so that my white text is written on ... a white background. For instance on the active tab item header :  I have tried : - - to force the use of the Windows Classic theme in the application resources :``` <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/PresentationFramework.Classic;V3.0.0.0;31bf3856ad364e35;component/themes/classic.xaml" /> </ResourceDictionary.MergedDictionaries> ``` This last attempt worked great for all controls, except the tab control which still displays as above. Any idea ? : I am suspecting this behaviour is due to the custom style I have to apply to the tab control : ``` <Window.Resources> <Style x:Key="Custom"> <Setter Property="Control.Background" Value="#FF47C7C8" /> <Setter Property="Control.Foreground" Value="White" /> </Style> <Style TargetType="TabControl" BasedOn="{StaticResource Custom}" /> </Window.Resources> ``` So how can I get the classic theme with custom colors ?

Im trying to think how to do this with html elements.  There is nothing special about the colors, so I don't need to make them images. Do note that the text is right aligned. Also, the color bar goes up to the text from the left. So this could be implemented by having the text float right with background color white, and a div with the background color set right next to it (and then a clear). Or instead of floats, I can do text align-right and get a similar effect. Here is the kicker. I'm using a javascript library (shouldn't matter which one) to create an animation. The animation is the bars shrink to the left, and end up like so:  The problem with the float or text-align methods are that too many values have to be changed to transition between the two states. The javascript animation effects tend to want to change a couple predefined values, like width or font-size. In order to transfer from picture 1 to picture 2 using the float or text-align methods, I must remove the floating/text-align then set the width of the bar color, but that doesn't work if I want to keep the javascript overhead minimal for such a simple task. I've tried absolute positioning/widths, but I can't get anything to make the text right aligned AND have the bars meet at the same point on the left. I'm hoping maybe I'm just blind of a simple solution, but as I see it, I need one element that has the text positioned to the right somehow, and an element that takes up as much room possible beside it for the color... AND the element that has the color should be able to take a width, while having the text follow beside it. Thank you.

I've always wanted to create custom components in Java, or customize existing ones, but my searches never resulted in anything useful. So I decided to ask the StackOverflow community: And when I mean customizing, I'm not talking about changing colors, fonts etc. I mean customize them. Here are two mockup example components:  I started this question mainly to find how to create the above two custom components. But then I realized that there isn't a general question about hacking swing components. So I thought it would be better to have a list of resources. In case you are wondering how do the two components in the mockup work, here it is: A customized JScrollPane that has two Scrollbars for each orientation. Each scrollbar can act differently. For example, the outer ones scroll normally and the inner ones move the view in a more [Picasa](http://picasa.google.com/)-like way. I actually got a working(!) answer from google groups [here](http://groups.google.com/group/comp.lang.java.programmer/browse_thread/thread/7a3c3558d7924661/11e7beb95c003575?#11e7beb95c003575), but that was just code. The second one is a custom JComboBox which, when the popup list is expanded, has a JComponent at the end. This can be anything, from a simple JLabel with an icon, to a JButton that manipulates the list in a way. But this question isn't about those specific components. It's about .

I'm not that familiar with COM and was hoping that someone out there, who is, could help verify what I have below is correct. If I have two completely separate Requests (request 1 & request 2), then this creates two separate instances of my WebApplication. So far so boring. If each instance then contacts the SAME web service, then presumably two instances of the Web Service are also instantiated. This is where it gets interesting. These web services create a .NET assembly which then references an in-process (registered via regsvr32) COM-dll (via Interop). Is my diagram correct?  This COM-DLL connects to the database, performs a query, returns data to the web service which then returns the data in JSON to the client. All done AJAXy. The other question I have is - is this okay performance-wise? I don't see why it shouldn't scale, and be able to return data to the user

As you can see, the output's colors are totally messed up... Thanks in advance for any help! -Hoff

I'd like to be able to highlight the wrap margin/text width in vim by changing the background color (or maybe just a line?). A lot of IDEs have this. I mocked up what I'm talking about:  Anyone know if this can be done in macvim or gvim?

So the last couple of days my dev webpage for ssrs has been looking really weird, as if it's not getting styled by css at all. I'm not the only person that is seeing it like this. We just rebooted the server and it didn't have any effect. If you know what it causing this, please help. another symptom is that i can't modify security settings now.

I am developing a website using forms and one of the browsers being targeted is unfortunately IE 6 and 7. I am having an issue with CSS and IE's rendering of form elements that are styled. I have written a test case, and it is as such (also available online at [http://xistence.osnn.net/testcases/ie67fieldset/](http://xistence.osnn.net/testcases/ie67fieldset/)): ``` <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <title>IE [6|7] Wha?</title> <style type="text/css"> html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, font, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td { margin: 0; padding: 0; border: 0; outline: 0; font-weight: inherit; font-style: inherit; font-size: 100%; font-family: inherit; vertical-align: baseline; } /* remember to define focus styles! */ :focus { outline: 0; } body { line-height: 1; color: black; background: white; } #req fieldset { border: 0; border-top: 1px solid #000; padding: 0em 1em 0em 1em; } #req legend + label { margin-top: 0.5em; } #req legend { font-size: 1.2em; } #req label { display: block; background: none; } #req input, #req textarea { position: relative; display: block; left: 200px; top: -1em; margin-bottom: -0.3em; } #req input[type="text"], #req textarea { width: 300px; } #req textarea { height: 3.6em; } #req input[type="text"], #req textarea { border: 1px solid #0a0; } #req label.required + input[type="text"], #req label.required + textarea { border: 1px solid #a00; } #req input[type="submit"] { position: relative; top: 0; margin: 0; left: 200px; margin-top: 0.5em; } #req input[type="hidden"] { display: none; } </style> </head> <body> <form id="req"> <fieldset> <legend>Contact Information</legend> <label for="name" class="required">Name: </label> <input type="text" id="name" name="name"></input> <label for="phone" class="required">Phone Number: </label> <input type="text" id="phone" name="phone"></input> <label for="email">Email: </label> <input type="text" id="email" name="email"></input> </fieldset> <fieldset> <legend>Personal Info</legend> <label for="sports">Sports:</label> <input type="text" id="sports" name="sports"></input> <label for="spentonline">Hours spent online: </label> <input type="text" id="spentonline" name="spentonline"></input> <label for="moreinfo">Tell us about yourself: </label> <textarea id="moreinfo" name="moreinfo"></textarea> </fieldset> <fieldset> <input type="submit" value="Submit" /> </fieldset> </form> </body> </html> ``` I have also taken two screen shots, one of IE 7 and one of IE 8, IE 7 and IE 6 agree on this styling so I have not bothered to take a screen shot of IE 6. IE [6|7]:  IE 8:  Has anyone seen this bug before? Where did I go wrong? What do I have to remove to make it work in IE 6/7 without having extra lines going through my input boxes. The extra lines are removed when the border-top is gone on the fieldset, but that is not a solution since doing so removes the whole visual separation. --- It is fixed. the margin-bottom on the textarea and input[type="text"] was causing IE 6/7 to have a rendering bug. Removed those and all is well. I guess I can deal with the extra space between the elements on the page!

I'm writing a console program that can accept 1 to 3 files. I'm using `OpenFileDialog` three times to accept the files, but the second and third time the file dialog is behind the console window, making it hard to notice. Any way to get it to appear above? An image of the problem:  The relevant code is: ``` static bool loadFile(ref List<string> ls) { OpenFileDialog f = new OpenFileDialog(); if (f.ShowDialog() == DialogResult.OK) { Console.WriteLine("Loaded file {0}", f.FileName); ls.Add(f.FileName); return true; } else { return false; } } [STAThread] static void Main(string[] args) { // sanity check if (args.Length > 3) { Console.WriteLine("Sorry, this program currently supports a maximum of three different reports to analyze at a time."); return; } else if (args.Length == 0) { List<string> fL = new List<string>(); for (int k = 0; k < 3; k++) { if (!loadFile(ref fL)) break; } if (fL.Count == 0) { InfoDisplay.HelpMessage(); return; } else { args = fL.ToArray(); } } // main program ... } ```

I have a problem about div position relative alignment. I want the second div to be fixed in position even if I remove the first div. The problem is that the second div adjusts its position when the first div is removed. My question is how can I retain the position of the second div even if I remove the first div? Thanks :) This code: ``` <div style="border: 1px solid red;width:400px;height:150px;margin:0px auto;" > <div style="border: 1px solid red; position: relative; width: 262px; height: 20px; top: 20px; left: 20px;">div-1</div> <div style="border: 1px solid red; position: relative; width: 262px; height: 20px; top: 60px; left: 20px;">div-2</div> </div> ``` Will output:  Then if the first div is removed, the second div adjusts its position. This code: ``` <div style="border: 1px solid red;width:400px;height:150px;margin:0px auto;" > <div style="border: 1px solid red; position: relative; width: 262px; height: 20px; top: 60px; left: 20px;">div-2</div> </div> ``` Will output:

I have a site that lists several upcoming events, and each event has a comment button to leave comments. It looks like this (it's in swedish, but I think you can figure out the structure): [shipit.se](http://www.shipit.se/dump/event.png) The div containing the textarea for writing the comment is initially hidden, and when clicking the 'comment'-icon it is displayed using the following javascript: ``` <script language="javascript" type='text/javascript'> function showhide_comment(comment_id, change_id) { if (document.getElementById(comment_id).style.display == 'none') { if (document.getElementById(change_id).style.display == 'block') { document.getElementById(change_id).style.display = 'none'; document.getElementById(comment_id).style.display = 'block'; document.getElementById(change_id).style.display = 'block'; } else { document.getElementById(comment_id).style.display = 'block'; } } else { if (document.getElementById(change_id).style.display == 'block') { document.getElementById(change_id).style.display = 'none'; document.getElementById(comment_id).style.display = 'none'; document.getElementById(change_id).style.display = 'block'; } else { document.getElementById(comment_id).style.display = 'none'; } } } ``` The script contains a hack to display the hidden div correctly in IE when another (initially hidden) div is also displayed in which changes can be made to the event. But never mind that. The php-code to display the comment form looks like this: ``` //Comment form, initially hidden echo "<div id=\"comment" . $row->id . "\" class=\"submit-comment\" style=\"display: none\">"; echo "<form name=\"make_comment\" method=\"post\" action=\"submit_comment.php\">"; echo "Kommentar:<br/>"; echo "<textarea name=\"comment\" class=\"comment\" rows=\"0\" cols=\"0\"></textarea><br/>"; echo "<input type=\"hidden\" name=\"event_id\" value=\"$row->id\"/>"; echo "<input class=\"comment\" type=\"submit\" name=\"submit_comment\" value=\"Skicka\" />"; echo "</form>"; echo "</div>"; ``` This code lies inside a loop which displays all upcoming events that are stored in a mySQL database. As can be seen, the divs are given variable names like comment1, comment2, etc. in order to bind the comments to the correct event. This is the code to display the comment-icon and linking it to the javascript: ``` echo "<li class=\"icon-left\"> <a href=\"javascript:showhide_comment('comment" . $row->id . "', 'change" . $row->id . "')\"> <img src=\"images/comment-24x24.png\" title=\"Kommentera körning\" alt=\"Kommentera körning\" /> </a></li>"; ``` What I would like to do is to put the focus inside the correct textarea field that becomes visible when the comment-icon is clicked so that the user can start typing directly. I have tried to modify the javascript above using focus(), but I just can't get it to work. Any ideas on how I can achieve what I want? Thanks. /Linus

I'm not 100% sure it wasn't always this way and I never noticed... but I'm pretty sure this is new and something got messed up somewhere. I am able to assign work items to a user named LOCAL SERVICE (see screenshot) in TFS 2008 (Workgroup Edition). This seems wrong, but I have no idea how to fix the issue. It's not the end of the world, but it's bugging me. Thanks in advance for any help.

I'm an artist involved with building various sorts of computer controlled machines. I've started prototyping a gimble-based XY painting machine and have realized that the maths needed are out of my reach. I'm a decent enough programmer but not strong in math- esp. 3D math. To get a sense of what I'm needing to do, it might be helpful to look at the rig: Early prototype:    [http://roypardi.com/gimble/gimbleSmall.MOV](http://roypardi.com/gimble/gimbleSmall.MOV) (small video) [http://roypardi.com/gimble/gimbleLarge.mov](http://roypardi.com/gimble/gimbleLarge.mov) (larger video) The two inner rings represent the X/Y axes and are controlled by stepper motors. I want to be able to use both raster images and vector data (gcode). So I need to be able to address a point in 2D space on the paper/from my data and have the gimble figure out what orientation it needs to be at in order to get there (i.e. how much to step each motor). I've been searching out 2D > 3D projection, Euler angles, etc. but I'm out of my depth. Any pointers, pushes in the right direction, or code snippets would be most welcome. I can make sense of most programming languages.

Is there a way in SQL Server Management Studio 2005 (or later) to change the Windows Authentication user (as you could in SQL Server 2000 and older)? This is the general connection properties dialog(note the greyed out UID/PWD when selecting Windows Auth):  FYI - One workaround is to use `runas` but I'm looking for a solution that will allow me to work with multiple Windows accounts across multiple servers (and across multiple domains).

I feel really stupid for asking this but I have been thrashing for over 8 hours. How do I get the Selected Item to show its text in my WPF combo box when selected?  Above is an option dialog that allows users to select and configure the available tournament displays. The problem is the selected combo box item shows the UserControl instead of the Display name. : ``` //_displayer is a private member populated using MEF //[ImportMany(typeof (IDisplayer))] //private IEnumerable<IDisplayer> _displayers; DisplayTypeComboBox.ItemsSource = _displayers; ``` ``` <ComboBox Name="DisplayTypeComboBox" Grid.Column="1" Grid.ColumnSpan="2" Grid.Row="1" IsEditable="False" SelectionChanged="DisplayTypeComboBox_SelectionChanged"> <ComboBox.ItemTemplate> <DataTemplate> <ComboBoxItem Content="{Binding DisplayerName}" /> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> ``` ``` public interface IDisplayer { string DisplayDataLocation { get; set; } string DisplayerName { get; } string DisplayerDescription { get;} bool WatcherEnabled { get; } UserControl View { get; } string DisplayerImageLeft { get; set; } string DisplayerImageRight { get; set; } void Update(); } ```

I am overloading the delegate method `-tableView:heightForRowAtIndexPath:` and using `-sizeWithFont:constrainedToSize:` to programmatically set the height of the cell, based on the text in that cell: ``` - (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { switch (indexPath.section) { case(kAboutViewOverviewSection): { switch (indexPath.row) { case(kAboutViewOverviewSectionRow): { NSString *text = NSLocalizedString(@"kAboutViewOverviewSectionFieldText", @""); CGSize s = [text sizeWithFont:[UIFont systemFontOfSize:14] constrainedToSize:CGSizeMake(280, 500)]; return s.height + 13; } default: { break; } } break; } default: { break; } } return 44.0; } ``` This works when the table is first drawn. However, when I change the orientation of the device, from portrait to landscape, the cell height does not change. I tried overriding the `-shouldAutorotateToInterfaceOrientation:` method in my table view controller: ``` - (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { [self.tableView reloadData]; return YES; } ``` This should reload the table data and (presumably) redraw the table cell views. But this does not have any effect. Is there a way to force a cell to redraw with a new height, when the device is rotated? : I have tried the following, to no effect: ``` - (void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { [self.tableView reloadData]; } ``` Here is what the application looks like in portrait orientation:  Here is what the application looks like in landscape orientation:  There is a gap between the top and bottom edges of the content. : Adjusting the size parameter via the table frame's width helped fix this display issue: ``` CGSize s = [text sizeWithFont:[UIFont systemFontOfSize:14] constrainedToSize:CGSizeMake([tableView frame].size.width,500)]; ```

I have been trying very hard to achieve rounded corners with IE6+jquery ui tabs. I have this page prepared: [http://jsbin.com/uzoko](http://jsbin.com/uzoko) (w/out dd_roundies) Ofcourse, the rounded corners work in FF but not IE6. Because some of the properties used in CSS are specific to FF and Chrome. I had asked this question yesterday  and based on that suggestion I used the DD_Roundies library. However, the sample page I provided up top doesnt have the ability to add DD_Roundies library so I cant really 'show' what exactly is wrong with the page when it is openeing in css. But after implementing DD_Roundies I can see the rounded corners in IE6 fine. HOWEVER, I have following problems: 1. ONLY the 'First' tabs seems to have rounded corners. When i click on second tab, it doesnt have rounded corners and so doesnt the third. 2. when I move away from First tab, it seems to have a border with color #990000. All of this does not happen in FF @#$%@$!! Since I am unable to put DD_Roundies library code in jsbin I will put what I have relative to dd_roundies on my page, here: ``` DD_roundies.addRule('.ui-corner-all', '4px'); DD_roundies.addRule('.ui-corner-top', '2px 2px 0px 0px'); DD_roundies.addRule('.ui-corner-bottom', '0 0 4px 4px'); DD_roundies.addRule('.ui-corner-right', '0 4px 4px 0'); DD_roundies.addRule('.ui-corner-left', '4px 0 0 4px'); DD_roundies.addRule('.ui-corner-tl', '4px 0 0 0'); DD_roundies.addRule('.ui-corner-tr', '0 4px 0 0'); DD_roundies.addRule('.ui-corner-br', '0 0 4px 0'); DD_roundies.addRule('.ui-corner-bl', '0 0 0 4px'); ``` I am not good at CSS to begin with and then correcting css so it works with freaking ie6 is whole another battle that I can use some help in. Please! Also, as suggested in the question I asked yesterday, I tried using images as well. I used cornershop website to create two rounded corner images. [http://tinypic.com/r/30j1rgz/5](http://tinypic.com/r/30j1rgz/5) and [http://tinypic.com/view.php?pic=50joqq&s=5](http://tinypic.com/view.php?pic=50joqq&s=5) but with these when I changed 'Interaction States' section of the css and property `.ui-state-active a, .ui-state-active a:link, .ui-state-active a:visited` to the following ``` background: #990000; font-weight: bold; color: #ffffff; text-decoration: none; outline: none; background: url(nw.gif) no-repeat top left; background: url(ne.gif) no-repeat top right; ``` then I got even weirder restuls :(

Does anyone have an example of how to draw the blue "unread dot" used in Apple's Mail App? This one in specific:  Drawing an ellipse is straight forward with Quartz2d, but the subtle use of shadows+gradients make this look really 3d.

I'm onto [problem 245](http://projecteuler.net/index.php?section=problems&id=245) now but have hit some problems. I've done some work on it already but don't feel I've made any real steps towards solving it. Here's what I've got so far: We need to find n=ab with a and b positive integers. We can also assume gcd(a, b) = 1 without loss of generality and thus phi(n) = phi(ab) = phi(a)phi(b). We are trying to solve:   Hence:  At this point I figured it would be a good idea to actually see how these numbers were distributed. I hacked together a brute-force program that I used to find all (composite) solutions up to 10: ``` 15, 85, 255, 259, 391, 589, 1111, 3193, 4171, 4369, 12361, 17473, 21845, 25429, 28243, 47989, 52537, 65535, 65641, 68377, 83767, 91759 ``` Importantly it looks like there [won't be too many](http://www08.wolframalpha.com/input/?i=15%2C+85%2C+255%2C+259%2C+391%2C+589%2C+1111%2C+3193%2C+4171%2C+4369%2C+12361%2C+17473%2C+21845%2C+25429%2C+28243%2C+47989%2C+52537%2C+65535%2C+65641%2C+68377%2C+83767%2C+91759) less than the 10 limit the problem asks. The most interesting/ useful bit I discovered was that k was quite small even for the large values of n. In fact the largest k was only 138. (Additionally, it seems k is always even.) Considering this, I would guess it is possible to consider every value of k and find what value(s) n can be with that value of k. Returning to the original equation, note that it can be rewritten as:  Since we know k:  And that's about as far as I have got; I'm still pursuing some of my routes but I wonder if I'm missing the point! With a brute force approach I have found the sum up to 10 which is 5699973227 (only 237 solutions for n). I'm pretty much out of ideas; can anyone give away some hints? --- : A lot of work has been done by many people and together we've been able to prove several things. Here's a list: n is always odd and k is always even. k <= 10. n must be squarefree. I have found every solution for when n=pq (2 prime factors) with p>q. I used the fact that for 2 primes q = k+factor(k^2-k+1) and p = k+[k^2-k+1]/factor(k^2-k+1). We also know for 2 primes k < q < 2k. For n with 2 of more prime factors, all of n's primes are greater than k.

I need to run an application on the server. I have an executable file, which runs perfectly well on my own permissions through terminal services. It also runs well on my own machine through the asp.net when I run the site with my VS. When I tried running my site on the real IIS it just hanged. I tried changing the credentials of the StartInfo to my own, and also tried Impresonate=true in the web.config to myself. In both cases it still didn't work. I keep getting the following error (when run under my credentials and entering the server on /console)  I also have "Allow service to interact with desktop" checked in the IIS options. Anyone here knows what I am missing? Some option I should check, or maybe some other way of doing what I need? Thanks.

I'm taking a look at this widget, and it appears to be a UIPickerView, however I haven't seen anything provided by the iPhone SDK API that allows for horizontal scrolling only. Mostly it's all done vertically. Also there appears to be a custom graphic around this picker, so it might not be that either. I'm curious if anyone is able to determine if this is indeed a UIPickerView or perhaps a hacked up UIScrollView? The widget is handy -- and I like its use. I found it in some random groceries app in the app store. Here is the screenshot:  Thanks all.

I think I've found the cause: Document Info window in IB has a warning: Bummer. --- I've built nib in Interface Builder that has `UITabBarController` at top level and switches between `UINavigationController`s. It works fine when everything is in a single `nib` file, but I'd like to use separate `nib` files for `UINavigationController`s. Starting with Apple's TabBar template, if I just change class of SecondView to `UINavigationController`, it all breaks:  and all I get is this: ``` // imgur has lost the image, sorry // ``` Is it possible to have separate file for `UINavigationController` without programmatically setting everything? I would like `TabBarController` to handle loading and unloading of nibs.

What's the best way to implement an interface that looks like this in rails?  Currently I'm using Searchlogic, and it's a tad painful. Problems include: - Making sure certain operations remain orthogonal -- for example, if you select "Short Posts" and then search, your search results should be restricted to short posts.- Making sure the correct link gets the "selected" class. Right now the links are `<a>`'s, so maintaining this state client-side is tricky. I'm hacking it by having the AJAX response to, say, sorting return a new sort links section with the correct link "selected". Using radio buttons instead of `<a>` tags would make it easier to maintain state client-side -- maybe I should do that?

: That's it folks! Bounty deadline is here, and after some tough deliberation, I have decided that [Boojum's entry](https://stackoverflow.com/questions/891643/twitter-image-encoding-challenge/929360#929360) just barely edged out [Sam Hocevar's](https://stackoverflow.com/questions/891643/twitter-image-encoding-challenge/904874#904874). I will post more detailed notes once I've had a chance to write them up. Of course, everyone should feel free to continue to submit solutions and improve solutions for people to vote on. Thank you to everyone who submitted and entry; I enjoyed all of them. This has been a lot of fun for me to run, and I hope it's been fun for both the entrants and the spectators. I came across [this interesting post](http://www.flickr.com/photos/quasimondo/3518306770/in/set-72057594062596732/) about trying to compress images into a Twitter comment, and lots of people in that thread (and a [thread on Reddit](http://www.reddit.com/r/programming/comments/8lwmw/guy_encodes_an_image_in_a_single_tweet140_chars/)) had suggestions about different ways you could do it. So, I figure it would make a good coding challenge; let people put their money where their mouth is, and show how their ideas about encoding can lead to more detail in the limited space that you have available. I challenge you to come up with a general purpose system for encoding images into 140 character Twitter messages, and decoding them into an image again. You can use Unicode characters, so you get more than 8 bits per character. Even allowing for Unicode characters, however, you will need to compress images into a very small amount of space; this will certainly be a lossy compression, and so there will have to be subjective judgements about how good each result looks. Here is the result that the original author, [Quasimondo](http://www.flickr.com/photos/quasimondo/), got from his encoding (image is licensed under a [Creative Commons Attribution-Noncommercial license](http://creativecommons.org/licenses/by-nc/2.0/deed.en)):  Can you do better? ### Rules 1. Your program must have two modes: encoding and decoding. 2. When encoding: Your program must take as input a graphic in any reasonable raster graphic format of your choice. We'll say that any raster format supported by ImageMagick counts as reasonable. Your program must output a message which can be represented in 140 or fewer Unicode code points; 140 code points in the range U+0000–U+10FFFF, excluding non-characters (U+FFFE, U+FFFF, U+nFFFE, U+nFFFF where n is 1–10 hexadecimal, and the range U+FDD0–U+FDEF) and surrogate code points (U+D800–U+DFFF). It may be output in any reasonable encoding of your choice; any encoding supported by GNU iconv will be considered reasonable, and your platform native encoding or locale encoding would likely be a good choice. See Unicode notes below for more details. 3. When decoding: Your program should take as input the output of your encoding mode. Your program must output an image in any reasonable format of your choice, as defined above, though for output vector formats are OK as well. The image output should be an approximation of the input image; the closer you can get to the input image, the better. The decoding process may have no access to any other output of the encoding process other than the output specified above; that is, you can't upload the image somewhere and output the URL for the decoding process to download, or anything silly like that. 4. For the sake of consistency in user interface, your program must behave as follows: Your program must be a script that can be set to executable on a platform with the appropriate interpreter, or a program that can be compiled into an executable. Your program must take as its first argument either encode or decode to set the mode. Your program must take input in one or more of the following ways (if you implement the one that takes file names, you may also read and write from stdin and stdout if file names are missing): Take input from standard in and produce output on standard out. my-program encode <input.png >output.txt my-program decode <output.txt >output.png Take input from a file named in the second argument, and produce output in the file named in the third. my-program encode input.png output.txt my-program decode output.txt output.png 5. For your solution, please post: Your code, in full, and/or a link to it hosted elsewhere (if it's very long, or requires many files to compile, or something). An explanation of how it works, if it's not immediately obvious from the code or if the code is long and people will be interested in a summary. An example image, with the original image, the text it compresses down to, and the decoded image. If you are building on an idea that someone else had, please attribute them. It's OK to try to do a refinement of someone else's idea, but you must attribute them. ### Guidelines These are basically rules that may be broken, suggestions, or scoring criteria: 1. Aesthetics are important. I'll be judging, and suggest that other people judge, based on: How good the output image looks, and how much it looks like the original. How nice the text looks. Completely random gobbledigook is OK if you have a really clever compression scheme, but I also want to see answers that turn images into mutli-lingual poems, or something clever like that. Note that the author of the original solution decided to use only Chinese characters, since it looked nicer that way. Interesting code and clever algorithms are always good. I like short, to the point, and clear code, but really clever complicated algorithms are OK too as long as they produce good results. 2. Speed is also important, though not as important as how good a job compressing the image you do. I'd rather have a program that can convert an image in a tenth of a second than something that will be running genetic algorithms for days on end. 3. I will prefer shorter solutions to longer ones, as long as they are reasonably comparable in quality; conciseness is a virtue. 4. Your program should be implemented in a language that has a freely-available implementation on Mac OS X, Linux, or Windows. I'd like to be able to run the programs, but if you have a great solution that only runs under MATLAB or something, that's fine. 5. Your program should be as general as possible; it should work for as many different images as possible, though some may produce better results than others. In particular: Having a few images built into the program that it matches and writes a reference to, and then produces the matching image upon decoding, is fairly lame and will only cover a few images. A program that can take images of simple, flat, geometric shapes and decompose them into some vector primitive is pretty nifty, but if it fails on images beyond a certain complexity it is probably insufficiently general. A program that can only take images of a particular fixed aspect ratio but does a good job with them would also be OK, but not ideal. You may find that a black and white image can get more information into a smaller space than a color image. On the other hand, that may limit the types of image it's applicable to; faces come out fine in black and white, but abstract designs may not fare so well. It is perfectly fine if the output image is smaller than the input, while being roughly the same proportion. It's OK if you have to scale the image up to compare it to the original; what's important is how it looks. 6. Your program should produce output that could actually go through Twitter and come out unscathed. This is only a guideline rather than a rule, since I couldn't find any documentation on the precise set of characters supported, but you should probably avoid control characters, funky invisible combining characters, private use characters, and the like. ### Scoring rubric As a general guide to how I will be ranking solutions when choosing my accepted solution, lets say that I'll probably be evaluating solutions on a 25 point scale (this is very rough, and I won't be scoring anything directly, just using this as a basic guideline): - - - - - - - - - - - - - - - - - - ### Reference images Some folks have asked for some reference images. Here are a few reference images that you can try; smaller versions are embedded here, they all link to larger versions of the image if you need those: [](http://www.cs.cmu.edu/~chuck/lennapg/lena_std.tif) [](http://upload.wikimedia.org/wikipedia/commons/6/6a/Mona_Lisa.jpg) [](http://upload.wikimedia.org/wikipedia/commons/2/24/Cornell_box.png) [](http://ephemera.continuation.org/stackoverflow/challenge/so-logo.png) ### Prize I am offering a (plus the 50 that StackOverflow kicks in) for the solution that I like the best, based on the above criteria. Of course, I encourage everyone else to vote on their favorite solutions here as well. ### Note on deadline This contest will run until the bounty runs out, about 6 PM on Saturday, May 30. I can't say the precise time it will end; it may be anywhere from 5 to 7 PM. I will guarantee that I'll look at all entries submitted by 2 PM, and I will do my best to look at all entries submitted by 4 PM; if solutions are submitted after that, I may not have a chance to give them a fair look before I have to make my decision. Also, the earlier you submit, the more chance you will have for voting to be able to help me pick the best solution, so try and submit earlier rather than right at the deadline. ### Unicode notes There has also been some confusion on exactly what Unicode characters are allowed. The range of possible Unicode code points is `U+0000` to `U+10FFFF`. There are some code points which are never valid to use as Unicode characters in any open interchange of data; these are the and the . Noncharacters are defined in the [Unidode Standard 5.1.0 section 16.7](http://www.unicode.org/versions/Unicode5.0.0/ch16.pdf) as the values `U+FFFE`, `U+FFFF`, `U+``FFFE`, `U+``FFFF` where is `1`–`10` hexadecimal, and the range `U+FDD0`–`U+FDEF`. These values are intended to be used for application-specific internal usage, and conforming applications may strip these characters out of text processed by them. Surrogate code points, defined in the [Unicode Standard 5.1.0 section 3.8](http://www.unicode.org/versions/Unicode5.0.0/ch03.pdf) as `U+D800`–`U+DFFF`, are used for encoding characters beyond the Basic Multilingual Plane in UTF-16; thus, it is impossible to represent these code points directly in the UTF-16 encoding, and it is invalid to encode them in any other encoding. Thus, for the purpose of this contest, I will allow any program which encodes images into a sequence of no more than 140 Unicode code points from the range `U+0000`–`U+10FFFF`, excluding all noncharacters and surrogate pairs as defined above. I will solutions that use only assigned characters, and even better ones that use clever subsets of assigned characters or do something interesting with the character set they use. For a list of assigned characters, see the [Unicode Character Database](http://unicode.org/Public/UNIDATA/UnicodeData.txt); note that some characters are listed directly, while some are listed only as the start and end of a range. Also note that surrogate code points are listed in the database, but forbidden as mentioned above. If you would like to take advantage of certain properties of characters for making the text you output more interesting, there are a [variety of databases of character information](http://unicode.org/Public/UNIDATA/) available, such as a [list of named code blocks](http://unicode.org/Public/UNIDATA/Blocks.txt) and [various character properties](http://unicode.org/Public/UNIDATA/PropList.txt). Since Twitter does not specify the exact character set they support, I will be lenient about solutions which do not actually work with Twitter because certain characters count extra or certain characters are stripped. It is preferred but not required that all encoded outputs should be able to be transferred unharmed via Twitter or another microblogging service such as [identi.ca](http://identi.ca/). I have seen some documentation stating that Twitter entity-encodes <, >, and &, and thus counts those as 4, 4, and 5 characters respectively, but I have not tested that out myself, and their JavaScript character counter doesn't seem to count them that way. ### Tips & Links - - [ImageMagick](http://www.imagemagick.org/)[Python Imaging Library](http://www.pythonware.com/products/pil/)- [this quick guide](http://www.azillionmonkeys.com/qed/unicode.html)[this detailed FAQ on UTF-8 in Linux and Unix](http://www.cl.cam.ac.uk/~mgk25/unicode.html)- - [PPM format](http://en.wikipedia.org/wiki/Netpbm_format)[ImageMagick](http://www.imagemagick.org/)

I'm using the ASP.NET MVC and the ADO.NET Entity Framework together. I want my Views and Controllers strongly-typed. But how am I supposed to handle entity associations? Here's a simple example: A Person has one Department. A Department has zero or more People.  My controller passes an instance of a Person object and a collection of all the Department objects to the View. ``` public class PersonController : Controller { ... // // GET: /Person/Create public ActionResult Create() { Person Model = new Person(); Model.Id = Guid.NewGuid(); ViewData["Departments"] = db.Department; return View(Model); } ... } ``` My View has a "Department" DropDownList with all departments as options. ``` <% using (Html.BeginForm()) {%> <fieldset> <legend>Fields</legend> <p> <label for="Id">Id:</label> <%= Html.TextBox("Id") %> <%= Html.ValidationMessage("Id", "*") %> </p> <p> <label for="Name">Name:</label> <%= Html.TextBox("Name") %> <%= Html.ValidationMessage("Name", "*") %> </p> <p> <label for="Department">Family:</label> <%= Html.DropDownList("Department", new SelectList((IEnumerable)ViewData["Departments"], "Id", "Name"))%> <%= Html.ValidationMessage("Department", "*")%> </p> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %> ``` But, the Person object posted to the controller has ``` public class PersonController : Controller { ... // // POST: /Person/Create [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(Person Model) { try { db.AddToPerson(Model); db.SaveChanges(); return RedirectToAction("Index"); } catch { return View(); } } ... } ``` Why isn't the selected Department from DropDownList "Department" automatically added to the model Person? How do I use the ADO.NET Entity Framework and ASP.NET MVC with strongly-typed Views and Controllers?

Why on sites like Stack Overflow, Techcrunch, Smashing Magazine, etc. are the page titles (i.e. the text at the top of the page) clickable URLs that redirect to the same page that the user is on?

I am currently designing a role based authentication system for resources where many users have different access rights to it. A role may be a single user, or a group of roles (so a role is a tree of roles). (see graphic below)  A resource can have multiple authentication properties (like read, write, delete), where each of this is a list of roles allowed to do access the operation. (see graphic below)  The problem is if I want to check if a user has the right to access a property, i have to traverse n trees in worst case (where n is the number of roles assigned to an property). So for example to check if 'Max' may read the property I might have to check the Marketing, Management and Administration trees if they contain 'Max'. --- Do you know of any algorithm or alternative approach which removes the quite expensive tree searches while maintaining the role system or something equally powerful. The perfect case would be some lookup like O(log(n)) for n roles. Thanks, Fionn

I am getting married this coming Saturday (May 30 2009). We are poor. So, instead of hiring a DJ, I want my friend to kick off mp3 playlists from a laptop to be played through a PA system. Well I had a vision for some software that would be perfect for this. Here is that vision:  I want this to be so that my friend can't screw this up and I think that if my vision were a reality then there would be no screwing up. And now for the programming question? How can I play mp3's from .net code? I am currently experimenting with NAudio, but I don't know if I can make it fade the files in/out. Are there any other free libraries out there that could help me? Thanks for any input. Time is of the essence. # PEOPLE! Focus on the programming question! If I ever need to work with audio in the future, your answers could be the keys to my destiny.

Have been scatching my head about this - and I reckon it's simple but my geometry/algebra is pretty rubbish, and I can't remember how to do this stuff from my school days! EDITED: I have a list of coordinates with people stood by them - I need an algorithm to order people from top left to bottom right in a list (array), and the second criteria demands that coordinates that are closer towards the top left origin take prescendance over all others - how would you do this? The code should show the order as: 1. Tom 2. Harry 3. Bob 4. Dave See diagram below:

I have the following html/css that is causing problems in Firefox 1.5 and 2, but is working correctly in IE6/7/8, Safari, Chrome, Opera and Firefox 1 and 3. ``` <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>Firefox Bug</title> <style type="text/css"> * { border: 0; padding: 0; margin: 0; } #wrapper { width: 500px; min-height: 550px; height: auto !important; height: 550px; border: 5px solid blue; position: relative; display: inline; overflow: auto; float: left; } #content { border: 5px solid green; } #bottom { border: 5px solid red; position: absolute; bottom: 0; right: 0; width: 200px; height: 100px; } </style> </head> <body> <div id="wrapper"> <div id="content"> Foo </div> <div id="bottom"> Bar </div> </div> </body> </html> ``` In the browsers that are working correctly, the bottom element shows up on the bottom right of the wrapper element. However, in Firefox 2, the bottom element is at the bottom of the content element. I cannot figure out why this is happening, any help would be greatly appreciated.

in my (puzzle) game the pieces are drawn on-screen using a `CALayer` for each piece. There are 48 pieces (in an 8x6 grid) with each piece being 48x48 pixels. I'm not sure if this is just too many layers, but if this isn't the best solution I don't know what is, because redrawing the whole display using Quartz2D every frame doesn't seem like it would be any faster. Anyway, the images for the pieces come from one big PNG file that has 24 frames of animation for 10 different states (so measures 1152 x 480 pixels) and the animation is done by setting the `contentsRect` property of each `CALayer` as I move it. This actually seems to work pretty well with up to 7 pieces tracking a touch point in the window, but the weird thing is that when I initially start moving the pieces, for the first 0.5 a second or so, it's very jerky like the CPU is doing something else, but after that it'll track and update the screen at 40+ FPS (according to Instruments). So does anyone have any ideas what could account for that initial jerkiness? The only theory I could come up with is it's decompressing bits of the PNG file into a temporary location and then discarding them after the animation has stopped, in which case is there a way to stop Core Animation doing that? I could obviously split the PNG file up into 10 pieces, but I'm not convinced that would help as they'd all (potentially) still need to be in memory at once. OK, as described in the comment to the first answer, I've split the image up into ten pieces that are now 576 x 96, so as to fit in with the constraints of the hardware. It's still not as smooth as it should be though, so I've put a bounty on this. I've linked one of the images below. Essentially the user's touch is tracked, the offset from the start of the tracking is calculated (they can one move horizontal or vertical and only one place at a time). Then one of the images is selected as the content of the layer (depending on what type of piece it is and whether it's moving horizontally or vertically). Then the `contentsRect` property is set to chose one 48x48 frame from the larger image with something like this:- ``` layer.position = newPos; layer.contents = (id)BallImg[imgNum]; layer.contentsRect = CGRectMake((1.0/12.0)*(float)(frame % 12), 0.5 * (float)(frame / 12), 1.0/12.0, 0.5); ``` btw. My theory about it decompressing the source image a-fresh each time wasn't right. I wrote some code to copy the raw pixels from the decoded PNG file into a fresh `CGImage` when the app loads and it didn't make any difference. Next thing I'll try is copying each frame into a separate `CGImage` which will get rid of the ugly `contentsRect` calculation at least.  Further back-to-basics investigation points to this being a problem with touch tracking and not a problem with Core Animation at all. I found a basic sample app that tracks touches and commented out the code that actually causes the screen to redraw and the `NSLog()` shows the exactly the same problem I've been experiencing: A long-ish delay between the `touchesBegin` and first `touchesMoved` events. ``` 2009-06-05 01:22:37.209 TouchDemo[234:207] Begin Touch ID 0 Tracking with image 2 2009-06-05 01:22:37.432 TouchDemo[234:207] Touch ID 0 Tracking with image 2 2009-06-05 01:22:37.448 TouchDemo[234:207] Touch ID 0 Tracking with image 2 2009-06-05 01:22:37.464 TouchDemo[234:207] Touch ID 0 Tracking with image 2 2009-06-05 01:22:37.480 TouchDemo[234:207] Touch ID 0 Tracking with image 2 ``` Typical gap between `touchesMoved` events is 20ms. The gap between the `touchesBegin` and first `touchesMoved` is ten times that. And that's with no computation or screen updating at all, just the `NSLog` call. Sigh. I guess I'll open this up a separate question.

I'm building a software repository on top of the Django framework. Because it will contain a lot of files, i want it to make some sense when looking at it through a file manager. So i grouped the files first by the URL of a program they belong to and then by first two letters of that URL. Here's how it looks:  The schema looks like this: ``` class File(models.Model): # If called like upload_to, don't put a slash in front of the result # because we already have one in settings.MEDIA_ROOT def get_absolute_url(self, filename=None): return '%sfiles/%s/%s/%s' % ('' if filename else '/', self.download.url[:2], self.download.url, filename or self.name) name = models.FileField(upload_to=get_absolute_url, max_length=255) size = models.IntegerField() title = models.CharField(blank=True, max_length=255) download = models.ForeignKey('Download', related_name='files') class Download(models.Model): url = models.SlugField(unique=True, max_length=255) title = models.CharField(max_length=255) ``` There is, however, a minor problem: FileField will store the entire generated path instead of just the name, which i would rather like to avoid. Is there any way to override (probably in my own field class) what FileField writes to the database and how it reconstructs the path after loading the raw field?

Greetings. I've been using vim for years, and I've recently started toying with XCode. One of the things I really like about XCode is that it will complete words me hitting `<TAB>`. For instance, in this image below I only need to type `NSSObj` and the rest is filled in automatically, no special keystroke required.  I'd like to reproduce this effect in vim. To be clear, this question is not about how to get tab/omni-completion working in vim. I've already got tab/omni completion working just fine and that's not a problem. The question is: does anyone know how to get vim to autocomplete ?

I discovered that it is possible to extract the hard-coded strings from a binary. For example the properties view of [Process Explorer](http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx) displays all the string with more than 3 characters. Here is the code of a simple executable that I wrote to simply test it: ``` #ifndef _WIN32_WINNT #define _WIN32_WINNT 0x0501 #endif #include <stdio.h> #include <tchar.h> #include <Windows.h> int _tmain(int argc, _TCHAR* argv[]) { _TCHAR* hiddenString1 =_T("4537774B-CC80-4eda-B3E4-7A9EE77991F5"); _TCHAR* hiddenString2 =_T("hidden_password_or_whatever"); for (int i= 0; i<argc; i++) { if (0 == _tcscmp(argv[i],hiddenString1)) { _tprintf (_T("The guid argument is correct.\n")); } else if (0 == _tcscmp(argv[i],hiddenString2)) { _tprintf (_T("Do something here.\n")); } } _tprintf (_T("This is a visible string.\n")); //Keep Running Sleep(60000); return 0; } ``` The strings can clearly be extracted from the corresponding executable:  I think that it is a little too easy to find the strings. My questions are: 1. How to simply hide hiddenString1 or hiddenString2 in the executable? 2. Is there a more secure way to use "cheat code" than with some obscure hidden input?

: I was recently playing around with GDI+ to draw a "Disc" displaying a sweeping color change through 360 degrees. (I dug up some HSL to RGB code to loop through HSL(1,1,1) -> HSL(360,1,1)) Regarding the disc, I first drew a full solid circle using the above, and then a second circle in Grey over the center to give the following  So this is all fine... but I realised that GDI+ is insulating us from a lot of the tricky match that's going on here by way of the `FillPie` method. Also, `FillPie` requires you to supply a bounding rectangle for the pie as opposed to a Radius Length. It also does a full segment fill and doesnt allow you to specify a part of that segment only. Can anyone point me in the direction of some Math functions or give any explanation on what forumla I would need to calculate the area & plot points of the following "Green Filled Area" given: ``` Point `c` - an x,y co-ordinate Angle `A` - an angle from horizontal Angle `B - an angle from horizontal where `B` - `A` == the sweep angle Length `r` - a distance from `c` Length `r2` - a distance from `c` where `r2` - `r` == the `height` of the segment to be filled. ```  Links to Math sources are fine but I've had a quick google & look at Wolfram Math and could find what I was looking for. Also, if there was some way to generate a sequence of bounding (x,y) co-or's that could be passed as a `Point[]` to Graphics.FillPolygon, that'd be cool too.

I am interested in visualizing the data and accuracy is not a high priority. Is there a safe way to calculate the clipping value to remove these values, or should I use all FFT matrices for each sample set to come up with an average number ? regards Edit: ``` from numpy import * import wave import pymedia.audio.sound as sound import time, struct from pylab import ion, plot, draw, show fp = wave.open("500-200f.wav", "rb") sample_rate = fp.getframerate() total_num_samps = fp.getnframes() fft_length = 2048. num_fft = (total_num_samps / fft_length ) - 2 temp = zeros((num_fft,fft_length), float) for i in range(num_fft): tempb = fp.readframes(fft_length); data = struct.unpack("%dH"%(fft_length), tempb) temp[i,:] = array(data, short) pts = fft_length/2+1 data = (abs(fft.rfft(temp, fft_length)) / (pts))[:pts] x_axis = arange(pts)*sample_rate*.5/pts spec_range = pts plot(x_axis, data[0]) show() ``` Here is the plot in non-logarithmic scale, for synthetic wave file containing 500hz(fading out) + 200hz sine wave created using Goldwave.

I am making a favorite list where you can add items through javascript and remove them again. The values are stored in cookies to remember the list when the user returns. The problem I have is that the method to remove the items from the list doesn't get run, unless there has been a postback first. My code to remove items look like this: ``` function removeFavorite(OrderId) { debugger; var cookieValues = jQuery.cookie('FavoriteList'); var cookieArray = cookieValues.split(","); for (var i = 0; i < cookieArray.length; i++) { if (cookieArray[i] == OrderId) { cookieArray.splice(i, 1); } } jQuery('li#liFavoriteOrder_' + OrderId).remove(); jQuery.cookie('FavoriteList', cookieArray.join(",")); } ``` and the code to call the method looks like this: ``` <a onclientclick="removeFavorite(1272331)" style="cursor: pointer;"> ```  and the list looks like ``` <ul id="ulFavoriteList"> <li id="FavoriteId_1272331"> Milk <a onclientclick="removeFavorite(1272331)" style="cursor: pointer;"> <img src="/Images/Icons/bullet_toggle_minus.png"/> </a> </li> </ul> ``` The code to add to to the list looks a bit like this (short version): ``` jQuery('<li id=\"liFavorite_' + OrderId + '\"><a target=\"_blank\" href=\"' + url + '\">' + OrderName + '</a><a style="cursor:pointer;" onclientclick="removeFavorite(' + OrderId+ ')"><img src="/Images/Icons/bullet_toggle_minus.png" /></a></li>').appendTo('ul#ulFavoriteList'); ```

How do you build your own FastCGI interface in PHP? I'd like to do something similar to what [they're doing in Perl](http://www.perl.com/doc/manual/html/lib/CGI/Fast.html), but in PHP. Is it even possible? Would it be faster? (That is, I'd like to be able to load a web app framework into memory, and then just have FastCGI call a method I provide for every request. So not the more generic preloading of the PHP-interpreter that is happening in the "default" PHP FastCGI setup.) cheers! (: Isn't Mongrel and RoR doing this as well?) Ok I've made a freakin' diagram now :)

I created a plist that contains an NSDictionary structure. The key is a label (which I use to populate tableview cell.text) and the value is a file name that I want to use to 'dynamically' populate cell.image. The exact png filenames are loaded into the project. To make things easier (so I thought), I load the plist into an NSDictionary, then pull that apart into two arrays (using allKeys and allValues). In attempting to set a cell image, I dont understand why this works: ``` cell.image = [UIImage imageNamed:@"bad.png"]; ``` and this does not (in simulator - I get an app crash and barfing in debugger): ``` cell.image = [UIImage imageNamed:[rowImageList objectAtIndex:indexPath.row]]; ``` I can put this next line right before the second piece of code and it works just fine, so it appears that I am getting an NSString from objectAtIndex: ``` NSLog(@"Image name: %@", [rowImageList objectAtIndex:indexPath.row]); ``` I have also tried creating a temp NSString and assigning [rowImageList objectAtIndex:] to it, then using that NSString to supply imageNamed:. Here is some info from debugger: > -[NSCFArray length]: unrecognized selector sent to instance 0x262d910Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFArray length]: unrecognized selector sent to instance 0x262d910' Let me know if you need more info/code. Edit: Here's how I populate rowImageList: ``` NSArray *myRowImages = [[NSArray alloc] init]; myRowImages = [searchFilterList allValues]; self.rowImageList = [myRowImages copy]; [myRowImages release]; //where searchFilterList is an NSDictionary that I loaded from a plist ``` Here's a screenshot of my plist: [IMG][][1](https://i.stack.imgur.com/XlPcb.jpg) [/IMG] Edit: revised rowImageList population: ``` NSMutableArray *myRowImages = [[NSMutableArray alloc] init]; NSEnumerator *enumerator = [searchFilterList objectEnumerator]; id object; while ((object = [enumerator nextObject])) { [myRowImages addObject:[object objectAtIndex:0]]; } self.rowImageList = myRowImages; //edit: added self. prefix [myRowImages release]; ```

Calculating the [k-core](http://en.wikipedia.org/wiki/K-core) of a graph by iteratively pruning vertices is easy enough. However, for my application, I'd like to be able to add vertices to the starting graph and get the updated core without having to recompute the entire k-core from scratch. Is there a reliable algorithm that can take advantage of the work done on previous iterations? For the curious, the k-core is being used as a preprocessing stage in a clique finding algorithm. Any cliques of size 5 are guaranteed to be part of the 4-core of a graph. In my data set, the 4-core is much smaller than the whole graph so brute-forcing it from there might be tractable. Incrementally adding vertices lets the algorithm work with as small of a data set as possible. My set of vertices is infinite and ordered (prime numbers), but I only care about the lowest numbered clique. Edit: Thinking about it some more based on akappa's answer, detecting the creation of a loop is indeed critical. In the graph below, the 2-core is empty before adding F. Adding F does not change the degree of A but it still adds A to the 2-core. It's easy to extend this to see how closing a loop of any size would cause all of the vertices to simultaneously join the 2-core. Adding a vertex can have an effect on the coreness of vertices an arbitrary distance away, but perhaps this is focusing too much on worst-case behavior.

Good afternoon, we're having a semi-weird problem here with a legacy activex dll that needs to be used in a .net project and strangely it works perfectly fine (adding it as a reference and all its functionality) on one developer's machine, but on no other ones, the build-server complains about a faulty reference etc etc. Whenever e.g. I try to re-add the .dll, I get the following, kinda shy-on-details error-message:  Any ideas / suggestions why it might not work in e.g. my environment? The project file etc is a standard class library one for .net 3.5, and we all use the same files/code-base. Cheers & Thanks, -Jörg

I'm trying to put some folders on my hard-drive into an array. For instance, vacation pictures. Let's say we have this structure: - - - - - - - - - - - - I want to have something like that, as an array. Meaning I have 1 big array and in that array are more arrays. Each set and subset gets its own array. I'm trying to make it look something like this: ``` Array ( [Set 1] => Array([0] => Item 1 of Set 1, [1] => Item 1 of Set 1,...) [Set 2] => Array([Subnet 1] => Array([0] => Item 1 of Subset 1 of Set 2,[1] => ...), [Subnet 2] => Array([0] => ..., ..., ...), ..., [0] => Random File) [set 3] => Array(...) ... ) ``` I came across this: [http://www.the-art-of-web.com/php/dirlist/](http://www.the-art-of-web.com/php/dirlist/) But that's not what I'm looking for. I've been meddling with it but it's giving me nothing but trouble. Here's an example, view source for larger resolution(no clicking apparently...).

I need to display some HTML content as it will be printed. Basically, I want to emulate the browser print preview feature. I'm not sure how to do this just with HTML/CSS/JavaScript. The only solution I came up is to convert the HTML to PDF so it´s split into pages and then convert that PDF to images and print each image one bellow the other. It will be really helpfull if someone can point a more straight forward method. I'm not even sure if this is posibble. BTW, I'm using PHP in the backend, so if there is a PHP class for this it will be helpfull. The page size for diplaying it will be letter no matter what the user have configured This how it should look in the browser:

 Hi guys, I am making some iPhone graph thingy. Here is my problem. I have one view controller and inside it two views graphView and segmented control view. I first draw graph view, than segmented control one. I want to have the functionality that when I click on some of the segmented control's buttons, I reload data and draw new graph. Right now I am doing that inside - (void)segmentAction:(id)sender just by adding another view like [self addSubview: aGraphView]. The problem is that this view is now covering segmented control like this  The question is how to not to lose segmented control in this process? :)

Whenever I add the min0height property to the DIVs to make them 100%, it doesn't work. I have added them to all of the DIVs, including height: 100%; and min-height: 100%; but nothing works. What would I do to make it extend all the way? It just cuts off the background of the sidebar and the background color of the content area.  (Forgot to label a part. The content area with the white background is .col1) ``` @charset "UTF-8"; /* CSS Document */ img { border-style: none; color: #FFF; text-align: center; } body { background-color:#000; margin:0; padding:0; border:0; /* This removes the border around the viewport in old versions of IE */ width:100%; } .sidebar { background-image:url(../images/sidebar/background.png); background-repeat:repeat-y; font: 12px Helvetica, Arial, Sans-Serif; color: #666; z-index:1; } .menu { background-image:url(../images/top_menu/background.png); background-repeat:repeat-x; height:25px; clear:both; float:left; width:100%; position:fixed; top:0px; z-index:5; background-color:#000; } .bottom_menu { background-image:url(../images/bottom_menu/background.png); background-repeat:repeat-x; height:20px; z-index:2; font: 12px Helvetica, Arial, Sans-Serif; clear:both; float:left; width:100%; position:fixed; bottom:0px; } .colmask { position:relative; /* This fixes the IE7 overflow hidden bug and stops the layout jumping out of place */ clear:both; float:left; width:100%; /* width of whole page */ overflow:hidden; /* This chops off any overhanging divs */ } .sidebar .colright { float:left; width:200%; position:relative; left:225px; background:#fff; } .sidebar .col1wrap { float:right; width:50%; position:relative; right:225px; } .sidebar .col1 { margin:30px 15px 0 225px; /* TOP / UNKNOWN / UNKNOWN / RIGHT */ position:relative; right:100%; overflow:hidden; } .sidebar .col2 { float:left; width:225px; position:fixed; top:0px; left:0px; margin-top:25px; margin-left:5px; right:225px; } .clear { clear: both; height: 1px; overflow: hidden; } ``` ``` <body> <div id="container"> <div class="menu">Header Content</div> <div class="colmask sidebar"> <div class="colright"> <div class="col1wrap"> <div class="col1" id="contentDIV"> Content </div> </div> <div class="col2"> Sidebar Content </div> </div> </div> <div class="bottom_menu">Footer Content</div> </div> </body> ```

I'm trying to save data with following structure:  As you can see, there is HABTM association between and table. And another HABTM between and . I created following form: ``` <?php echo $form->create('Experience', array('action' => 'addClassic'));?> <?php echo $form->input('Experience.date', array('dateFormat' => 'DMY')); echo $form->input('Experience.time', array('timeFormat' => '24', 'empty' => array(-1 => '---'), 'default' => '-1')); echo $form->input('Experience.name'); echo $form->input('ExperiencesUser.1.note'); echo $form->input('ExperiencesUser.1.rating'); //echo $form->input('Tags.Tags', array('multiple' => 'multiple', 'options' => $tags)); //echo $form->input('ExperiencesUser.1.Tags', array('multiple' => 'multiple', 'options' => $tags)); //echo $form->input('ExperiencesUser.1.Tags.Tags', array('multiple' => 'multiple', 'options' => $tags)); echo $form->input('ExperiencesUser.1.confirmed', array('type' => 'hidden', 'value' => '1')); echo $form->input('ExperiencesUser.1.user_id', array('type' => 'hidden')); echo $form->input('ExperiencesUser.2.user_id', array('type' => 'hidden')); ?> <?php echo $form->end(__('Add', true));?> ``` And everything works well. method creates new Experience, assings this new experience to two users (via ) and sets the stuff around. What bothers me is that I want to assign some to newly created record (to the first one). I thought, that should be done via some of the commented stuff. Every line of this commented code creates form and sends data to , but it never gets saved. So my question is: What is the right syntax of or in my example to save data into ?

So I think I'm going to get buried for asking such a trivial question but I'm a little confused about something. I have implemented quicksort in Java and C and I was doing some basic comparissons. The graph came out as two straight lines, with the C being 4ms faster than the Java counterpart over 100,000 random integers.  The code for my tests can be found here; [android-benchmarks](http://code.google.com/p/android-benchmarks/source/browse/#svn/trunk) I wasn't sure what an (n log n) line would look like but I didn't think it would be straight. I just wanted to check that this is the expected result and that I shouldn't try to find an error in my code. I stuck the formula into excel and for base 10 it seems to be a straight line with a kink at the start. Is this because the difference between log(n) and log(n+1) increases linearly? Thanks, Gav

I have an app I must write that will utilize a database for each company we are able to get as a client. Unfortunately, the schemas for all the companies databases's are not identical, even though for this app they all have the basic information I need (even if their column names are different/in a different table). My solution to handling the multiple databases is to create an IRepository interface like: ``` List<User> getUsers(); List<Account> getAccounts(); void UpdateAccount(Account account); ``` etc. I'll write a DAL class for each database which will implement this interface. This class will use the appropriate LINQ datacontext for it's own database:  Here you can see the folders for Lowes, HomeDepot, and FrankLumber. Each one has a DAL class which implements IRepository. My question is, where should I handle the instantiation of the factory method so I can persist a new DAL class instance for each user who logs in, based on what "company" they belong to. So, if a lowes customer logs in it will call the RepositoryFactory passing it the user and return the appropriate DAL, which I can then call methods on polymorphically since I know they will implement the above methods. I'm new to ASP.NET MVC and MembershipProviders and could use some tips on how I should persist the instance of the DAL for each user after they log in.

How do I persist which database a user is associated with it using LINQ and ASP.NET MVC?
