  • What is the technical skill degree of your co-workers?

    - by bonefisher
    For now it has been around 4 years that I work as developer. Most of my team mates, from their tech-skill, programming ability and code practices view, are somewhere between junior and senior. In all my previous jobs, there was a real geek who was brilliant at coding/analyzing/lead, but the others were just 'average' programmers. How would you rank your co-workers as good developers from rank 1 (best) - 5 (worst) ?

    - by Naughty.Coder
    Should I learn C#3 or C#4 !? there are alot more books on C#3 than C#4 , would my programming abilities be outdated if I learned C#3 !? And another small question : there are books like : beginning Visual C# 2008 , and Illustrated C# 2008 . The question is : Do they mean the IDE when they mention Visual C# 2008 ?

  • FPGA Place & Route

    - by anon
    For programming FPGAS, is it possible to write my own place & route routines? [The point is not that mine would be better; the point is whether I have the freedom to do so] -- or does the place & route stage output into undocumented bitfiles, essengially forcing me to use proprietary tools? Thanks!

  • Implement animation in UIButton

    - by sasayins
    I'm new to cocoa and iphone programming and I want to implement an animation in UIButton. For example, I create a custom UIButton with a square image. Then when I press that UIButton, the square image will flip. Note that the square image is the image of the UIButton. [UIButton setImage:[UIImage imageNamed:@"square.png"]];

  • HTML 5 Canvas performance

    - by Vilius
    Hello there! I'm just started on playing around with the canvas HTML5-object. For the sake of performance tests, I have made a little ping pong game (http://bit.ly/arTPut). Apart from my quick'n'dirty programming skills, I believe, that there are also some performance boosts, I haven't used. Especially, the ball seams to be blue with a little red-touch, but by my decleration it should be yellow. Would be very nice, if someone could help me! Greetings, Vilius

  • Android: Learning the platform, have any app suggestions?

    - by David
    I'm beginning to learn mobile programming on the Android platform. I'm up for working with any particular base SDK. I just want to hear some suggestions from the community about what types of applications I should start with to help learn more advanced interactions with the platform. There are of course the Standard Hello World, calculator, etc. But by now I am bored with all of those. What do you all make when learning a new language?

  • Multi-Threaded Application - Help with some pseudo code!!

    - by HonorGod
    I am working on a multi-threaded application and need help with some pseudo-code. To make it simpler for implementation I will try to explain that in simple terms / test case. Here is the scenario - I have an array list of strings (say 100 strings) I have a Reader Class that reads the strings and passes them to a Writer Class that prints the strings to the console. Right now this runs in a Single Thread Model. I wanted to make this multi-threaded but with the following features - Ability to set MAX_READERS Ability to set MAX_WRITERS Ability to set BATCH_SIZE So basically the code should instantiate those many Readers and Writers and do the work in parallel. Any pseudo code will really be helpful to keep me going!

  • New interesting languages

    - by wvd
    Hello all, I've been programming for 4 years now and I feel it's time for a new language. I've been doing Python, Java and some C++/Erlang/Haskell along those 4 years but I'm looking for a new language. I'm mainly looking for one which I could use later when I'm getting hired, but it also needs to be relatively new. Any ideas? Thanks, William van Doorn

  • Why is Lisp used for AI?

    - by Cristián Romo
    I've been learning Lisp to expand my horizons because I have heard that it is used in AI programming. After doing some exploring, I have yet to find AI examples or anything in the language that would make it more inclined towards it. Was Lisp used in the past because it was available, or is there something that I'm just missing?

  • How to use Rx to asynchronously query Twitter search ?

    - by Jalfp
    Hi, I'm thinking about using Rx (Reactive Framework) in order to asynchronously query Twitter search API on a given keyword. The sample app I'd like to build should be able to display new tweets in the console. Do you think it is possible to do that ? Would it be simpler than using standard programming techniques ? How would you do that ? Thank ! Jeremy

  • Modifying text files and executing programs with command line parameters in c# or c++ on Linux

    - by Robert Harvey
    I have a need to create a utility in Suze Linux. The utility will make modifications to some text files, and then use the information in those text files to program a device in the computer using a different executable which accepts command line parameters. I am fluent in c#, but have never worked with Linux. Should I take the time to learn Gnu C++ to do this, or install Mono? How would I execute the programming utility and pass it command line parameters?

  • Approximate timings for various operations on a "typical desktop PC" anno 2010

    - by knorv
    In the article "Teach Yourself Programming in Ten Years" Peter Norvig (Director of Research, Google) gives the following approximate timings for various operations on a typical 1GHz PC back in 2001: execute single instruction = 1 nanosec = (1/1,000,000,000) sec fetch word from L1 cache memory = 2 nanosec fetch word from main memory = 10 nanosec fetch word from consecutive disk location = 200 nanosec fetch word from new disk location (seek) = 8,000,000 nanosec = 8 millisec What would the corresponding timings be for your definition of a typical PC desktop anno 2010?
