  • Qt: Is it possible to use mixins technique?

    - by Eye of Hell
    Hello. Qt library includes advanced meta-programming capabilities using they own preprocessing moc compiler. Does anyone knows, is it possible to create some kind of mix-ins via it? For example, i have a QString and want to add a method to it without sub-classing and changing existing code. Does Qt have such solutions for that?

    - by Nicolas Noël
    Hi, I'm looking for a python library for finding the longest common substring from a set of python strings. I'have read that it exist to way to solve this problem : - one using suffix trees - the other using dynamic programming. The method implemented is not important. Otherwise, it is important to have a implementation that can be use for a set of strings and not only two strings Thanks,

  • Creating a Virtual Webcam Device for OS X

    - by andsve
    I am looking for a solution to create a "virtual" webcam device under OS X (that acts just as a normal hardware webcam, but the application has full control over what to output). I'm fairly experienced with C++, but not so much with Objective-C and OSX/Cocoa programming. Anyone that can point me in the right direction, where to look and what I should be looking for? I've searched, but most of the results seems to focus on Windows and DirectX. Thanks!

  • Does anyone know a light Vim scheme which makes coding more readable and pleasant?

    - by janoChen
    I know a lot of nice dark schemes for Vim which makes coding more readable and pleasant such as ir_black, wombat, zenburn. Its weird but I haven't seen so many popular light themes (white background). Does anyone knows a light Vim scheme which makes code more readable and pleasant to see? (that makes code less confusing to distinguish, something like Visual studio's default scheme?)

  • Maintaining a secure database of user logins and info?

    - by Rafe Kettler
    I want to have a login form on a charity website I am building (it's for a friend, and I'm learning on the go), and I want to know what languages/software should I learn to build databases for user logins and info? Note: it HAS to be secure and relatively simple to learn for someone with moderate programming experience. Update: I understand that CMSs offer good tools for logins etc. but I want to do this all by myself.

  • Undead Windows 7 service

    - by Jan
    I created a Windows 7 service in Visual Studio 2010. Test install crashed and left lots of debris: service shows in the list of services but will not start ('Referenced file does not exist'), is impossible to uninstall ('Action valid only for services that are installed') and is not shown in the Programs and Features aplet. Is there a list of installed services that I could hack? Thanks, Jan

  • What's the best way to mix Ruby and other languages? (Especially C++)

    - by Andy
    Hi, I'm learning Ruby, and I'm starting to play with building extensions in C. I have Programming Ruby The Pragmatic Programmers' Guide and so I can follow that for the basic nuts and bolts. What I was wondering is if there already existed some nifty frameworks/whatever to help interoperability between Ruby and other languages, with C++ being the most important for me. I've tried googling, but the results focus on language comparisons, rather than language interoperability. TIA, Andy

  • TFS 2008 checks out code automatically on edit

    - by Jangwenyi
    I am working on a Visual Studio 2008 project that is already added to TFS server. I am not sure which settings and policies have been configured for the TFS (this is done by a separate dept, not developers) Every time I make an edit to a code file , the file is checked out automatically (without explicitly checking out the code file myself) Please help me locate this setting or policy because it is not very useful at the moment. Sometime you want to make a local change to try out something, and not necessarily check out the code....

  • How do I specify a project dependency with Hudson?

    - by Brett Ryan
    We have common library projects shared amongst many projects that are required to be checked out into a "Libraries" folder which a developer needs to checkout prior to opening the main project in visual studio. How I tell hudson that there is this dependency? I figured one thing I could do is setup a custom workspace and specify the location for all projects, but how do I wire up the dependency between them all? Is simply specifying "Build after other projects are built" enough?

  • What is a really simple explanation of unit testing?

    - by ensnare
    I've never done any unit testing before, and would like to learn what it is and how it can be useful in my Python code. I've read through a few Python unit testing tutorials online but they're all so complicated and assume an extended programming background. I'm using Python with Pylons to create a simple web app. Any simple examples would be greatly appreciated. Thanks!

  • How fast should an interpreted language be today?

    - by Tarbal
    Is speed of the (main/only viable) implementation of an interpreted programming language a criteria today? What would be the optimal balance between speed and abstraction? Should scripting languages completely ignore all thoughts about performance and just follow the concepts of rapid development, readability, etc.? I'm asking this because I'm currently designing some experimental languages and interpreters

  • What do you expect of an 'Experienced Developer'?

    - by ritu
    I have been programming for about 10 years: 7 years C++, 3 years MFC, 2 JSP/Servlets, and the last year .NET (since there was some overlap the total won't add up). The problem is now that I am looking for a new job, I don't know what the latest thing is in C++ AND Java AND .NET AND MFC and somehow at interviews I am expected to KNOW everything about these topics because I have them listed on my resume. Any suggestions?

  • Is there an extension or mode in Emacs similar to surround.vim?

    - by Chow
    Surround.vim is a nifty vim extension that allows you to surround blocks of text with , brackets, braces, and pretty much any arbitrary "surround" character. It supports paragraph and word surround, but I frequently use it in visual mode. I'm playing around with Emacs and wondering if there's something similar; something that will let me highlight a region and then have the marked region (or rectangle) enclosed with braces, brackets or tags.

  • Does EGit mandate installing JGit?

    - by Souper
    After using Git from the command line for a while, I am ready for the convenience a GUI plugin (for Eclipse) can offer. However, I prefer a Git plugin similar to to MS Visual Studio's Git Source Control Provider which is only a wrapper around the already installed msysgit. I really don't want two different Git implementations accessing the same repository. EGit sounds perfect - if it can use the already installed msysgit in my PC. But can it?

  • XS:Group causes Schema to fail validation

    - by paulwhit
    I have an XML document based on a Schema that uses the xs:group element to bunch elements together. The result is an entity where name, address and phone number are defined in a group. This fails Schema validation in MS (Visual Studio) as well as XERCES (oXygen XML editor) Is there a workaround?

  • In partial view: "The model item passed into the dictionary is of type"

    - by Dave
    I lack understanding of some basic MVC concepts, despite all my searching. I created an MVC project in Visual Studio, which contains the partial view _LogOnPartial.shtml. I just want to access information within the view pertaining to the user, to put in a user dropdown menu. When I try to put this at the top of the partial view cshtml page I get the above error: @model MyProject_MVC.Models.UserRepository When I try this I also get an error: @Html.Partial("_LogOnPartial", MyProject_MVC.Models.UserRepository) 'MyProject_MVC.Models.UserRepository' is a 'type', which is not valid in the given context

  • installing opencv for python issues

    - by vlad
    I'm running OS X Leopard. I followed this site to install it. Trying to run any demo script, I now get "No module named opencv.cv", which is obviously stopping me from doing any programming. I am running python 2.5.1 (yes, I know it's kind of old). Why would this be, and how can I solve it? Thanks
