  • Test to identify your development environment?

    - by lance
    The code has a runtime dependency which is not available in our development environment (and is available in test and prod). It's expensive to actually test for the dependency, and I want to test for the environment instead. if (isDevEnvironment) { // fake it } else { // actually do it } Without using appSettings, what code/technique/test would you use to set isDevEnvironment? Example answers: check machine name (partial or full) check for running instance of Visual Studio check for environment variable I'm hoping for a test I hadn't considered.

  • create a YYYY-MM-DD Daterange in JScript/Javascript.

    - by Marcus
    Hello. I need no generate a full daterange in JScript from a given Startdate to now. Startdate: 2010-03-25 2010-03-26 2010-03-27 ... 2010-05-30 I am very confused with Javascript Date. best would be a function to give a daterange as params and getting an Array of the formatted date back, something like that: range[0] = 2010-03-25 range[1] = 2010-03-26 range[2] = 2010-03-27 ... range[x] = 2010-05-30 I am so confused thanks for any hint marcus

  • Generating .po/.mo files

    - by Echilon
    I have a database full of translations I'd like to generate either .po or .mo files. I'm using C#, but I could also port an implementation from PHP if one exists. I can't find any examples in any languages using anything other than GNUs gettext utilities. Does anyone know of one?

  • Java JGraph subgraph

    - by Jeff Storey
    Is there a way to create a subgraph from a full graph in JGraph? When I update the subgraph, I want changes to propagate to the main graph. Does JGraph provide a relatively easy way for doing that out of the box (I couldn't seem to find one...)? thanks, Jeff

  • Silverlight ItemsControl with Alternating ItemTemplate

    - by Ray Booysen
    Silverlight does not support Alternating Item Templates in an ItemsControl. I have a few ideas in mind as to how to accomplish this, but to avoid polluting the potential answers, I'll leave them out. If you had to design a method of providing alternating templates (and I mean a full data template) for an ItemsControl, how would you accomplish this.

  • HTML APIs for touch devices?

    - by askvictor
    What HTML APIs are available for touch screen devices (e.g. tablet PCs)? I notice that GMail's iPad interface (and other mobile interfaces) doesn't scroll down in a normal web browser (pretending to be an iPad via a user-agent hack). How can one access this API on a PC? I have a school full of tablet PCs that aren't wonderful in tablet mode due to lack of application support, but there looks to be an increasing number of web-based apps that will fill this gap.

  • MySQL: LIMIT then RAND rather than RAND then LIMIT

    - by Larry
    I'm using full text search to pull rows. I order the rows based on score (ORDER BY SCORE) , then of the top 20 rows (LIMIT 20), I want to rand (RAND) the result set. So for any specific search term, I want to randomly show 5 of the top 20 results. My workaround is code based- where I put the top 20 into an array then randomly select 5. Is there sql way to do this?

  • changing vim's vertsplit character to ¦

    - by ldigas
    This is, I assume, codepage related, but doesn't hurt asking. How would one, on windows xp's cmd, gvim 7.2 change vertsplit character, so that instead of default | it is ¦ (so that it makes a full, and not an splitted line) ? That character is usually changed with set fillchars=vert:\| and I can copy paste the ascii graphics line there, but it comes out as garbage. I suppose I would have to change vim's internal codepage for it to show correctly ? Anyone knows how to do this ?

  • Find and replace in a block of text.

    - by David Tildon
    I have a database full of text fields that look like this: (paragraph of normal text) image:blog/clownboy.jpg (another paragraph) I'm trying to write a view helper for Rails that will take one of these big blocks of text, find bits like "image:blog/clownboy.jpg" and replace them with the corresponding <img src="blog/clownboy.jpg"> (without disturbing the surrounding whitespace) before outputting it to the user. I've been trying for an hour or so now, but I'm new to Ruby and the regular expressions are still a bit beyond me.

  • LRU cache design

    - by user297850
    Least Recently Used (LRU) Cache is to discard the least recently used items first How do you design and implement such a cache class? The design requirements are as follows: 1) find the item as fast as we can 2) Once a cache misses and a cache is full, we need to replace the least recently used item as fast as possible. How to analyze and implement this question in terms of design pattern and algorithm design?

  • How to quickly acquire and process real time screen output

    - by Akusete
    I am trying to write a program to play a full screen PC game for fun (as an experiment in Computer Vision and Artificial Intelligence). For this experiment I am assuming the game has no underlying API for AI players (nor is the source available) so I intend to process the visual information rendered by the game on the screen. The game runs in full screen mode on a win32 system (direct-X I assume). Currently I am using the win32 functions #include <windows.h> #include <cvaux.h> class Screen { public: HWND windowHandle; HDC windowContext; HBITMAP buffer; HDC bufferContext; CvSize size; uchar* bytes; int channels; Screen () { windowHandle = GetDesktopWindow(); windowContext = GetWindowDC (windowHandle); size = cvSize (GetDeviceCaps (windowContext, HORZRES), GetDeviceCaps (windowContext, VERTRES)); buffer = CreateCompatibleBitmap (windowContext, size.width, size.height); bufferContext = CreateCompatibleDC (windowContext); SelectObject (bufferContext, buffer); channels = 4; bytes = new uchar[size.width * size.height * channels]; } ~Screen () { ReleaseDC(windowHandle, windowContext); DeleteDC(bufferContext); DeleteObject(buffer); delete[] bytes; } void CaptureScreen (IplImage* img) { BitBlt(bufferContext, 0, 0, size.width, size.height, windowContext, 0, 0, SRCCOPY); int n = size.width * size.height; int imgChannels = img->nChannels; GetBitmapBits (buffer, n * channels, bytes); uchar* src = bytes; uchar* dest = (uchar*) img->imageData; uchar* end = dest + n * imgChannels; while (dest < end) { dest[0] = src[0]; dest[1] = src[1]; dest[2] = src[2]; dest += imgChannels; src += channels; } } The rate at which I can process frames using this approach is much to slow. Is there a better way to acquire screen frames?

  • Examples of CoffeeScript in NodeJS?

    - by Austin Hyde
    As a pet project, I am trying to get familiar with NodeJS and CoffeeScript, and am finding it hard to get the ball rolling. I've found plenty of examples of single-file super-simple apps like in CoffeeScript's examples folder, however, none of those really show what a full application would look like. I've also scrounged Google to no avail. Do you have any examples of medium-sized, multi-file CoffeeScript/NodeJS apps I could learn from?

  • Why change from WPF to Silverlight 4?

    - by stiank81
    I'm working on an application we made WPF instead of Silverlight as we wanted a full blown desktop application with the whole unique feeling and advantages that gives. However, with the announcement of Silverlight 4 I hear there is a buzz about Silverlight mostly being the preferred choice also for desktop applications. So; why should I consider moving my WPF application to Silverlight 4 - given that I still want a desktop application?

  • Summer Activity or Internship in Europe [2010] [closed]

    - by mrlinx
    I'm a graduate student looking for week(s) long activity in the summer. Because the summer isn't very long for students in my college, I'm not looking for a 3 month full-time internship, but some kind of activity where I can experience subjects related to computer science, entrepreneurship and team management. Do you know any? Recommend a better place to look for this?
