  • Extern variable at specific address

    - by AndiNo
    Using C++ and GCC, can I declare an extern variable that uses a specific address in memory? Something like int key attribute((__at(0x9000))); AFAIK this specific option only works on embedded systems. If there is such an option for use on the x86 platform, how can I use it?

  • C# - Fast and simple multi dimensional data structures?

    - by Jeremy Rudd
    I need to store multi-dimensional data consisting of numbers in a manner thats easy to work with. I'm capturing data in real time, and once processed I would destroy and GC older data. This data structure must be fast so it won't hit my overall app performance. The faster the better. What are my choices in terms of platform supported data structures? I'm using VS 2010. and .NET 4.

  • Is it possible to profile CPU / memory inside an Adobe AIR application?

    - by dain
    Couldn`t find any ActionScript native APIs even in the beta documentation, am I right supposing that this means the only way to measure CPU / memory consumption is by cooking up a custom native solution, hooking it up with AIR and making it work on each targeted platform? Basically the aim is to be able to have this information available inside AIR and not having to use an external application for profiling, not even Flex / Flash builder.

  • Rhomobile vs. Phonegap considerations

    - by NewB
    I'm debating between Phonegap and RhoMobile for cross platform mobile application development. I'm a web developer with experience in Ruby as well as the traditional web technologies (HTML, CSS, and Javascript). The backend of this application will be accessed via a web browser and built with Rails. What are my chief concerns when choosing between these platforms? Which would you recommend I go with and WHY? Thank you

    - by Greenhouse Gases
    I am attempting to learn how to develop on the Android platform but do not quite understand the relationship between Activities and Views, because according to the documentation an Activity is link to a UI object that the user can interact with, but if this is the case where does the whole idea of Views come in? There is probably a very basic explanation but I would appreciate a few pointers all the same. Thanks

    - by Pierreten
    Just got a chance to try out a cloud programming environment that let's you develop .net apps within the browser (http://coderun.com/ide/) I found it pretty interesting, since I was able to develop a mockup ASP.net site on an IPad. With javascript engines in browsers becoming faster and faster, cheap server infrastructure to compile on; will the cloud become the IDE platform of the future?

  • python interpreter waits for child process to die

    - by Moulik Kallupalam
    Contents of check.py: from multiprocessing import Process import time import sys def slp(): time.sleep(30) f=open("yeah.txt","w") f.close() if __name__=="__main__" : x=Process(target=slp) x.start() sys.exit() In windows 7, from cmd, if I call python check.py, it doesn't immediately exit, but instead waits for 30 seconds. And if I kill cmd, the child dies too- no "yeah.txt" is created. How do I make ensure the child continues to run even if parent is killed and also that the parent doesn't wait for child process to end?

    - by Michel
    Hi, i have a wcf service which runs perfectly on my dev machine (vs2010, target 3.5) but once deployed, it shows me the code behind of the service (actually the plain text of the .svc file) and not the normal service page: <%@ ServiceHost Language="C#" Debug="true" Service="SilverlightPoc.Web.FinanceData" CodeBehind="FinanceData.svc.cs" %> Anyone any idea why the .svc file is rendered as plain text and not as wcf service?

  • Future of IE9: Opacity + Performance

    - by chris_l
    I just tried the IE9 "Second Internet Explorer Platform Preview" - which supports CSS opacity now. That's nice, but I tried it with one of my website prototypes, and it's quite slow when scrolling etc. Admittedly, the prototype uses hundreds of images with opacity != 1, but everything is snappy with current versions of Firefox, Safari, Chrome and Opera. Does anybody know, if there are plans for IE9 to become faster in this area? Even rumours about this would be interesting in this case.

  • Do null SQLite Data fields take up extra memory?

    - by CSharperWithJava
    I'm using the built in sqlite library on the Android platform. I'm considering adding several general purpose fields that users will be able to use for their own custom applications, but these fields will be blank most of the time. My question is, how much overhead will these blank fields add to my database? Do null fields even take up per record memory in sqlite? If so, how much? I don't quite understand the inner workings of a sqlite database.

  • Breaking out of the Google App Engine Python lock-in?

    - by Alterlife
    Are there any guidelines to writing Google App Engine Python code that would work without Google's infrastructure on other platforms? Is there any known attempt to create an open source framework which can run applications designed for Google App Engine on other platforms? Edit: To clarify, the question really is: If I develop an application on Google App Engine now, will I be able to migrate to another platform later, or is it a lock in?
