  • how to connect android emulator to the internet

    - by Hoff
    hi folks, basic question but i haven't been able to figure it out: how to I connect my android emulator to the internet, e.g. to use the browser? I've found lots of advice on what do to when your connected through a proxy, but that's not the case here, my machine (win7) is directly connected to the router... thanks for your help, martin

  • How can we stop a running java process through windows cmd?

    - by Wing C. Chen
    I am a newbie in cmd, so please allow me to ask a stupid question: How can we stop a running java process through windows cmd? For example, if we start jetty(a mini web server) with the following cmd: start javaw -jar start.jar How do we find the process and stop it later? Obviously the following cmd does not work: stop javaw -jar start.jar

  • Why is a 16-bit register used with BSR instruction in this code snippet?

    - by sharptooth
    In this hardcore article there's a function find_maskwidth() that basically detects the number of bits required to represent itemCount dictinct values: unsigned int find_maskwidth( unsigned int itemCount ) { unsigned int maskWidth, count = itemCount; __asm { mov eax, count mov ecx, 0 mov maskWidth, ecx dec eax bsr cx, ax jz next inc cx mov maskWidth, ecx next: } return maskWidth; } the question is why do they use ax and cx registers instead of eax and ecx?

  • Display of colorblind images

    - by Michael
    Quick question: At this website here http://www.vischeck.com/examples/ there are a few pictures of numbers hidden within another color to test for color blindness. Is there any way that these images can be generated algorithmically?

  • css sprite button is jumping around

    - by Richard
    Hello everyone, Does anyone know what is causing the sprite rollover to jump around It is I think more likely a photoshop question, but I am not completely sure. I hope to get an answer here anyway, since I think most webdesigners/programmers problably worked with photoshop also. This is what I want the rollover to do example 1 and this is my testpage (see the play button) I made the sprite with spriteme.com thanks, Richard

  • wpf in-page dialog.

    - by Erin
    When I worked on web pages I used these a lot. While building a page out for WPF project the other day I ended up building a page that looked like it had an in-page dialog on it but it was the only thing on the page. My question here is. Has any one created such component that allows for easy creation of these kinds of dialogs.

  • How can I decide what to test manually, and what to trust to automated tests?

    - by bhazzard
    We have a ton of developers and only a few QA folks. The developers have been getting more involved in qa throughout the development process by writing automated tests, but our QA practices are mostly manual. What I'd love is if our development practices were BDD and TDD and we grew a robust test suite. The question is: While building such a testing suite, how can we decide what we can trust to the tests, and what we should continue testing manually?

  • Are event handlerss in JavaScript called in order?

    - by musicfreak
    I know this is a simple question, but I haven't had the chance to test it in any browser other than Firefox. If I attach multiple event handlers to a single event on a single DOM element, are the event handlers guaranteed to be called in the order they were added? Or should I not rely on this behavior?

  • c#: what is the purpose of wpf vs. winforms [closed]

    - by every_answer_gets_a_point
    i know wpf can be richer-looking, but what is the point of using them if they complicate things so much? for example if i want to do something on form load in wpf i have to through the trouble of writing this: public MyWindow() { Loaded += MyWindow_Loaded; } private void MyWindow_Loaded(object sender, RoutedEventArgs e) { // do work here } whereas in winforms all i do is double click on the form the question is what are the benefits of using wpf over winforms?

  • Programming graphics and sound on PC - Total newbie questions, and lots of them!

    - by Russel
    Hello, This isn't exactly specifically a programming question (or is it?) but I was wondering: How are graphics and sound processed from code and output by the PC? My guess for graphics: There is some reserved memory space somewhere that holds exactly enough room for a frame of graphics output for your monitor. IE: 800 x 600, 24 bit color mode == 800x600x3 = ~1.4MB memory space Between each refresh, the program writes video data to this space. This action is completed before the monitor refresh. Assume a simple 2D game: the graphics data is stored in machine code as many bytes representing color values. Depending on what the program(s) being run instruct the PC, the processor reads the appropriate data and writes it to the memory space. When it is time for the monitor to refresh, it reads from each memory space byte-for-byte and activates hardware depending on those values for each color element of each pixel. All of this of course happens crazy-fast, and repeats x times a second, x being the monitor's refresh rate. I've simplified my own likely-incorrect explanation by avoiding talk of double buffering, etc Here are my questions: a) How close is the above guess (the three steps)? b) How could one incorporate graphics in pure C++ code? I assume the practical thing that everyone does is use a graphics library (SDL, OpenGL, etc), but, for example, how do these libraries accomplish what they do? Would manual inclusion of graphics in pure C++ code (say, a 2D spite) involve creating a two-dimensional array of bit values (or three dimensional to include multiple RGB values per pixel)? Is this how it would be done waaay back in the day? c) Also, continuing from above, do libraries such as SDL etc that use bitmaps actual just build the bitmap/etc files into machine code of the executable and use them as though they were build in the same matter mentioned in question b above? d) In my hypothetical step 3 above, is there any registers involved? Like, could you write some byte value to some register to output a single color of one byte on the screen? Or is it purely dedicated memory space (=RAM) + hardware interaction? e) Finally, how is all of this done for sound? (I have no idea :) )

  • How does assembly language interact with something like the Internet?

    - by Maulrus
    So I was thinking about languages the other day, and it struck me that any program written in a compiled language that interacts with the Internet is then translated into assembly that has to interact with the Internet. I've just begun learning a bit of x86 assembly to help me understand C++ a bit better, and I'm baffled by how something so low-level could do something like access the Internet. I'm sure the full answer to this question is much more than would fit in a SO answer, but could somebody give me maybe a basic summary?

  • Alternative to before </body> tag inline Javascript

    - by Mohammad
    I know inline Javascript is frowned upon and with the new on-the-fly Javascript compressors that check for idle/unused function usage and omit the unused code, it seems good practice to have all your Javascript in an external file. My question is, in situations like FOUC (flash of unstyled content) which usually require little snippets of code right before the closing </body> tag, is there a JQuery resolution that would serve the same purpose, but from a remote Javascript file linked in the <head> of the document?

  • MongoDB initialization error in Rails

    - by rube_noob
    I have an initialization script to set up my MongoDB connection in the config/initialization directory. It is my understanding that these initializers run after all of the plugins are initialized. The problem I am having is that when a particular plugin I am using is initialized, it tries to access the mongodb before I have set it up. I get this error: uninitialized class variable @@database_name in MongoMapper My question is: Where can I initialize Mongodb that will run after the mongodb gem has been loaded and before any of the plugins are initialized?
