• How to cycle through matrix blocks?

  - by luiss

  I have some matrix which I want to cycle through blocks, the matrix could be of many different sizes, but I can know the size, is there a way to fast cycle through blocks? i.e: to fast output the indexes of the blocks, suppose a matrix of 4*4 I should have: Block1: (0,0),(0,1)(1,0)(1,1) Block2: (0,2),(0,3)(1,2)(1,3) Block3: (2,0),(2,1)(3,0)(3,1) Block4: (2,2),(2,3)(3,2)(3,3) Where the indexes are (row,col). For blocks I mean a submatrix of size sqrt(matrixSize)* sqrt(matrixSize) where matrix is a matrix of matrixSize*matrixSize. For example a matrix of 4*4 has 4 blocks of 2*2, a 9*9 has 9 blocks of 3*3... I'm workdeing in C, but I think that the pseudocode is useful also, I only need the loop on the indexes... Thanks

• Any way to get TStringList.CommaText to not escape commas with quotes?

  - by Mason Wheeler

  I'm doing some work with code generation, and one of the things I need to do is create a function call where one of the parameters is a function call, like so: result := Func1(x, y, Func2(a, b, c)); TStringList.CommaText is very useful for generating the parameter lists, but when I traverse the tree to build the outer function call, what I end up with looks like this: result := Func1(x, y, "Func2(a, b, c)"); It's quoting the third argument because it contains commas, and that produced invalid code. But I can't do something simplistic like StringReplace all double quotes with empty strings, because it's quite possible that a function argument could be a string with double quotes inside. Is there any way to make it just not escape the lines that contain commas?

• Experimenting with data to determine value - migration/methods?

  - by TCK

  Hey guys, I have a LOT of data available to me, and want to experiment with data that isn't currently being used in production. The obvious solution seems to be to make a copy of production data and integrate it with what I want to play around with, but I was wondering if there was a better (less expensive?) way to do this. Both isolation and integration are important. I'd like to be able to keep lightweight/experimental data assets apart from high volume production data, but also be able to integrate (RELATIVELY) painlessly if experimental assets are deemed useful. Thanks.

• .NET framework: new features

  - by Budda

  Few weaks ago I've changed target .NET framework for my application to the 4th version. Recently my resharper told me that my variable "MetaDescription" hides property 'string System.Web.UI.Page.MetaDescription' After small investigation the peace of code that worked earlier: HtmlMeta MetaDescription = new HtmlMeta(); MetaDescription.Attributes.Add("name", "description"); MetaDescription.Attributes.Add("content", ((IFriendlySEO)Page).DescriptionString); Header.Controls.Add(MetaDescription); was replaced with much more readable: MetaDescription = ((IFriendlySEO)Page).DescriptionString; (same for MetaKeywords). Question: is there any useful source that can give a list of such new features? Thanks.

• Mouse configurable buttons for programming

  - by DavRob60

  Different mouse models has been already discussed. But all these mouse got configurable buttons. Has a programmer, how do you set them? I use The Microsoft Intellimouse Optical. So set the Left side button to "Copy" and the Right side button to "Paste". I did not set the Wheel click to anything. I'm curious to see if there is any better setup? UPDATE : I'm trying to find some interesting key I could map to my mouse buttons. Copy & paste are the best I' found so far, but i just want to know if there is something that could be more useful when programming.

• Solid FFmpeg wrapper for C#/.NET

  - by Lillemanden

  I have been searching the web for some time for a solid FFmpeg wrapper for C#/.NET. But I have yet to come up with something useful. I have found the following three projects, but all of them apears to be dead in early alpha stage. FFmpeg.NET ffmpeg-sharp FFLIB.NET So my question is if anyone knows of a wrapper project that is more mature? I am not looking for a full transcoding engine with job queues and more. Just a simple wrapper so I do not have to make a command line call and then parse the console output, but can make method calls and use eventlisteners for progress. And please feel free to mention any active projects, even if they are stil in the early stages.

• How to share sessions between PHP and ASP.net application?

  - by citronas

  My company took some old php application over. Due to our preference to ASP.net and to the lack of any documentation from the previous developer, we do not want to spend much resources on developing in PHP. For implementing new features, we will create an Asp.net application that has the same look to the user. We want to develop a kind of 'coexisting' web application. Therefore we must share sessions between an PHP and an Asp.net webapplication project, because there is a usermanagement involved with an existing MySQL database. (e.g. link 'A' directs to the PHP website, and link 'B' directs to the asp.net application) How can we share the session between and PHP and an asp.net application? And does anyone have a hint for this 'coexisting' thing, that might be useful in development? Edit: IIS 6 would be our targeted server, altough IIS 7.5 would also be an option

• What can I use for voluntary donations? (like Tipjoy)

  - by Ken

  There used to be a site called Tipjoy that would let me put a small "donate" button on a webpage, and users could donate small amounts (like 25c) to me easily. I think it was a pretty neat idea, since I want to have a way for people to give me money, and I don't like advertisements, and I don't update regularly enough to sell subscriptions like bloggers. I just have some simple web services and open-source program and I want an easy way for people to drop me some change if they think they're useful. I've found out that Amazon used to have a similar service, but it's also been shut down. Is there any similar web service available today? If not, what's the closest thing to offer -- a Paypal link?

• Display Img and Div inline - it's not rendered inline

  - by user359372

  In order to follow correct web standards, I've tried to layout image and div inline. In orde to achieve that - I've used display:inline property. But then I experienced the following issue: image renders from the center line, and div doesn't respect height parameter set to it. I've tried using line-height parameter, but that didn't give any useful results. I've also tried various combinations with setting margin/padding to some values or to auto, or replacing div with span, or wrapping img and div with additional divs. I've managed to achieve desired result by using position:absolute, but that doesn't help in cases where I want to use centered/relative positioning of the whole component... Any clues or ideas or troubleshooting hints? Please find the html example below: Test Page Some text that should be displayed in the center/middle of the div 123   Some text that should be displayed in the center/middle of the div

• Java: Local Enums

  - by bruno conde

  Today, I found myself coding something like this ... public class LocalEnums { public LocalEnums() { } public void foo() { enum LocalEnum { A,B,C }; // .... // class LocalClass { } } } and I was kind of surprised when the compiler reported an error on the local enum: The member enum LocalEnum cannot be local Why can't enums be declared local like classes? I found this very useful in certain situations. In the case I was working, the rest of the code didn't need to know anything about the enum. Is there any structural/design conflict that explains why this is not possible or could this be a future feature of Java?

• How do I use Zend Cache on this particular problem

  - by davykiash

  I have an action that renders two different view scripts based on whether the user is logged in or not. class IndexController extends Zend_Controller_Action { .... public function indexAction() { $auth = Zend_Auth::getInstance(); if($auth->hasIdentity()) { $this->render('indexregistered'); return; } else { $this->render('indexpublic'); return; } } .... } I have seen quite some useful examples on how to use the Zend Cache and they seem to be based on the fact that the action renders one particular script. What am really looking at is the best approach to cache the the indexpublic script does get quite some hits and I would live to avoid the Zend MVC overhead if possible.

• Storing links to internal content pages in ASP.NET MVC

  - by mare

  I'm using a route like this routes.MapRoute( "PageBySlug", RouteType.Regular, "{slug}", new {controller = "Page", action = "Display", slug = "Default"}, null ); to map request to ~/Some-Page-Slug to ~/Page/Display/Some-Page-Slug. When adding content, user can choose to link to existing pages to create references and I then store those links in this format in the datastore: "/Some-Page-Slug". When I run the app in Cassini and pull the link out from datastore and attach it to A tag it looks like this http://localhost:93229/Some-Page-Slug and this link works. But when running the application in virtual directory under some website in IIS, the attached link generates this URL http://localhost/Some-Page-Slug, when it should be http://localhost/virtualdir/Some-Page-Slug. Of course, this generates 404 error. How can I solve this to be universally useful and working under all circumstances? Should I store it differently in the database or should I transform it into correct form in my Views at runtime and how to do that?

• Is there a declarative language for data definitions?

  - by Jekke

  Reading about WPF and thinking about my application's data store at the same time led me to wonder if there are any languages or tools that allow you to define relational data in a declarative way? A shallow Google search suggests no such thing exists. Yet it seems so obviously useful. The kind of tool I have in mind would declaratively describe (at least) entities, relationships and views is a platform-agnostic way that would act as an abstraction layer between data-driven applications and their datastores. Does any such tool exist?

• C++ library for dealing with multiple HTTP connections

  - by JWood

  Hi, I'm looking for a library to deal with multiple simultaneous HTTP connections (pref. on a single thread) to use in C++ in Windows so it can be Win32 API based. So far, I have tried cURL (multi interface) which seems to be the most appropriate that I have found but my problem is that I may have a queue of 200 requests but I need to only run 4 of them at a time. This becomes problematic when one request may take 2 seconds and another may take 2 mins as you have to wait on all handles and receive the result of all requests in one block. If anyone knows a way round this it would be very useful. I have also tried rolling my own using WinHTTP but I need to throttle the requests so they would ideally need to be on a single thread and use callbacks for data which WinHTTP does not do. The best thing I've found which would solve all my problems is ASIHTTPRequest but unfortunately it's Mac OSX only. Thanks, J

• sOperator as and generic classes

  - by abatishchev

  I'm writing .NET On-the-Fly compiler for CLR scripting and want execution method make generic acceptable: object Execute() { return type.InvokeMember(..); } T Execute<T>() { return Execute() as T; /* doesn't work: The type parameter 'T' cannot be used with the 'as' operator because it does not have a class type constraint nor a 'class' constraint */ // also neither typeof(T) not T.GetType(), so on are possible return (T) Execute(); // ok } But I think operator as will be very useful: if result type isn't T method will return null, instead of an exception! Is it possible to do?

• Rails route rewriting quesiton

  - by Jonathan

  Hi guys, I think this is an easy question. I am using this useful Flash Document Reader called FlexPaper. I have it embeded in one of my Show pages. But when I click the a link on their tool bar to show the document in a new browser, it points to the following link ... http://0.0.0.0:3000/intels/FlexPaperViewer.swf?ZoomTime=0.5&FitPageOnLoad=false&PrintEnabled=false&SwfFile=%2FPaper.swf which doesn't work, but if I remove the "intels" from the path so the url looks like: http://0.0.0.0:3000/FlexPaperViewer.swf?ZoomTime=0.5&FitPageOnLoad=false&PrintEnabled=false&SwfFile=%2FPaper.swf It works fine. My question is what is the best way to handle this. Can you write a route that rewrites a url that starts with intels/FlexPaperViewer.swf and removes the intels prefix? What would that look like? Is there a better option? Thanks! Jonathan

• What is the C# equivalent of java.util.regex?

  - by peter.murray.rust

  I am converting Java code to C# and need to replace the use of Java's regex. A typical use is import java.util.regex.Matcher; import java.util.regex.Pattern; //... String myString = "B12"; Pattern pattern = Pattern.compile("[A-Za-z](\\d+)"); Matcher matcher = Pattern.matcher(myString); String serial = (matcher.matches()) ? matcher.group(1) : null; which should extract a capture group from a matched target string. I'd be grateful for simple examples. EDIT: I have now added the C# equivalent of the code as an answer. EDIT: Here is a tutorial on the use of the actual expressions. EDIT: Here is a useful comparison of C# and Java (and Perl.)

• How do you find out release, mailing list statistics information on open source projects

  - by Samuel

  We are interested in finding out some statistics of various frameworks Mailing list activity on say richfaces. Much similar to what is available on http://code.google.com (Low, Medium, High) + average number of emails per day | per month. Number of releases made in a year including patch, minor, major releases. We did look at the maven repositories but that wasn't very useful either. We did look at ohloh, but didn't get the desired information. Any other ideas on where to get this information (any maven-2 plugins)?

• Getting help on MATLAB's com.mathworks internals

  - by Richie Cotton

  It is possible to access bits of MATLAB's internal java code to programmatically change MATLAB itself. For example, you can programmatically open a document in the editor using editorServices = com.mathworks.mlservices.MLEditorServices; editorServices.newDocument() %older versions of MATLAB seem to use new() You can see the method signatures (but not what they do) using viewmethods. viewmethods(com.mathworks.mlservices.MLEditorServices) I have a few related questions about using these Java methods. Firstly, is there any documentation on these things (either from the Mathworks or otherwise)? Secondly, how do you find out what methods are available? The ones I've come across appear to be contained in JAR files in matlabroot\java\jar, but I'm not sure what the best way to inspect a JAR file is. Thirdly, are there functions for inspecting the classes, other than viewmethods? Finally, are there any really useful methods that anyone has found?

• shift happens videos

  - by hasan

  im sure you guys must have seen the shift happens video series. here's a link to them : http://www.youtube.com/results?search_query=shift+happens&search_type=&aq=f also, the recent hungry beast video about google, which can be found here: (SO doesnt allow new users more than one hyperlink, so please search on youtube for this one) what i'd like to ask you guys is this: is there a program that enables such videos to be made quickly or is it really just the creative genius of the respective authors? i think vidoes like these are extremely useful when you want to make an impact and would find many uses for such a program in my line of work. im hoping somebody can point me in the right direction. ps. i DO know of animoto, so please dont suggest that :P the problem with animoto is that it doesnt allow text manipulation like these videos. to be fair, that is a great product in itself, but im sure if you take a look, you'll see the difference that im talking abuot.

• visual studio 2005 is deleting the .svn folder in the bin\Debug directory - how to prevent this?

  - by M K Saravanan

  For some reason I need to check in a couple of files in the bin\Debug directory. For the past few weeks, I am noticing a strange behaviour from VS2005. Every time I recompile the code, it is deleting the .svn folder in the bin\Debug directory and hence svn is showing "obstructed" error. Even svn clean up doesn't help due to missing .svn folder. Is there any settings on VS2005 to prevent this? In the first place, why it is deleting .svn folder? This thread http://svn.haxx.se/tsvnusers/archive-2008-10/0019.shtml discuss about it but no useful solution to prevent this from happening. Any other suggestions?

• GEdit/Python execution plugin?

  - by Simon Woods

  Hi I'm just starting out learning python with GEdit plus various plugins as my IDE. Visual Studio/F# has a feature which permits the highlighting on a piece of text in the code window which then, on a keypress, gets executed in the F# console. Is there a similar facility/plugin which would enable this sort of behaviour for GEdit/Python? I do have various execution type plugins (Run In Python,Better Python Console) but they don't give me this particular behaviour - or at least I'm not sure how to configure them to give me this. I find it useful because in learning python, I have some test code I want to execute particular individual lines or small segments of code (rather then a complete file) to try and understand what they are doing (and the copy/paste can get a bit tiresome) ... or perhaps there is a better way to do code exploration? Many thx Simon

• Right way to create [self]respawning app in python

  - by grapescan

  I am using jabber bot written in python to log some MUC talks. Sometimes it drops on some network or XMPP problems. In this case I have to start it again by myself. The goal is to make it "self-respawning". I have some variants about how to do it. Bot is one process. Another process monitors its activity and starts it if bot died. Main process spawns bot subprocess and controls it. Also I think daemonizing bot process is useful here. Platform is Linux, as you could guess. What is the right way to solve this problem?

• Constructor in a Interface?

  - by Sebi

  I know its not possible to define a constructor in a interface. But im wondering why, because i think i could be very useful. So you could be sure that some fields in a class are defined for every implementaiton of this interface. For example consider the following message class: public class MyMessage { public MyMessage(String receiver) { this.receiver = receiver; } private String receiver; public void send() { //some implementation for sending the mssage to the receiver } } If a define a Interface for this class so that i can have more classes which implement the message interface, i can only define the send method and not the constructor. So how can i assure that every implementation of this class really has an receiver setted? If i use a method like setReceiver(String receiver) i can't be sure that this method is really called. In the constructor i could assure it.
