  • Does armcc optimizes non-volatile variables with -O0 ?

    - by Dor
    int* Register = 0x00FF0000; // Address of micro-seconds timer while(*Register != 0); Should I declare *Register as volatile while using armcc compiler and -O0 optimization ? In other words: Does -O0 optimization requires qualifying that sort of variables as volatile ? (which is probably required in -O2 optimization)

  • How to reorder type members with Resharper?

    - by AngryHacker
    Typical scenario: a class that a lot of people have worked on. I'd like to sort methods, properties, etc... in alphabetical order. I'd like to be able to do this within the region or globally in the class. I see the feature in Resharper to do it, but it does not seem to do anything.

  • Why is C++ backward compatible with C ? Why isn't there some "pure" C++ language ?

    - by gokoon
    C and C++ are different languages, blababla we know that. But if those language are different, why is it still possible to use function like malloc or free ? I'm sure there are all sort of dusty things C++ has because of C, but since C++ is another language, why not remove those things to make it a little less bloat and more clean and clear ? Is it because it allows programmers to work without the OO model or because some compilers doesn't support high-level abstract features of C++ ?

  • How can I run ARM code from external memory?

    - by samoz
    I am using an LPC2132 ARM chip to develop a program. However, my program has grown larger than the space on the chip. How can I connect my chip to some sort of external memory chip to hold additional executable code? Is this possible? If not, what do people normally do when they run out of chip space?

  • Does content always have to be in chronological order in an RSS feed?

    - by Chris Henry
    I run a site where users can upload content that is displayed in a gallery where other users can sort and filter that content. While implementing RSS feeds, I was wondering how common it was for an RSS feed to display items in an order that's different from chronological. For example, displaying content by Most Views first. This could be useful for someone wanting to keep tabs on trending content. How do RSS readers handle this, since most RSS feeds are ordered chronologically?

  • Assigning IDs to instances of a class (Pythonic)

    - by mellort
    I want to have each instance of some class have a unique integer identifier based on the order that I create them, starting with (say) 0. In Java, I could do this with a static class variable. I know I can emulate the same sort of behavior with Python, but what would be the most 'Pythonic' way to do this? Thanks

  • How to create a project template for Ruby on Rails projects?

    - by wgpubs
    When I build Rails applications I find myself doing the same things over and over again. This includes adding the same gems/plugins, configuration info and custom initializers, rake tasks etc... etc.... This can't be a good thing. So, is there a way to package all this repetitive code into some sort of project template ... so that I can do a "rails myapp" and have everything good to go from there? Btw, running 2.3.5 if that matters :) thanks

  • Accessing Subversion commit data externally

    - by gaoshan88
    I have need to access subversion data (commit messages, files updated, revision numbers, dates modified, author, etc.) externally. Is this something for some sort of subversion hook or is there a decent third party package for this or some other "best practice" way to approach accessing subversion data externally (and by external I mean from a php/ruby or python script... external to subversion itself)?

  • Visual Studio support for coding in CIL/IL/MSIL?

    - by jdk
    For the longest time I've been curious to code in Intermediate Language just as an academic endeavour and to gain a better understanding of what's "happening under the hood". Is there any sort of Visual Studio support for this in the form of: project templates, IntelliSense integration, and those kind of RAD features?

  • How to avoid strange characters before the request in firefox?

    - by murze
    Hi, on a website i'm currently developing I'm using jquery to do all sort of magic things :-) In firefox however, when I load jquery 1.4.2 there are sometimes funny characters in front of the request. You can see the strangers characters in this screenshot (thank you firebug). In safari, Chrome and IE these funny characters don't appear, jquery is loading fine in those browsers. Why are those characters appearing and how can I remove them? Thanks!!

  • License plate recognition

    - by WowtaH
    As a side-project I'm trying to create an app that scans license plates from passing cars from my living-room window. I have hooked up a high resolution camera to my system to capture (moving) images into my c# app. Now all I need is a way to interpret these images into something readable. I´m thinking about some sort of OCR-solution that is fast/accurate enough for moving images. Hope you can give me some direction!

  • Why do I get so many errors building my Android project with Ant?

    - by synic
    Now that I sort of know my way around the SDK/API, I've switched from Eclipse back to my favorite text editor, which means I have to use ant to build my project, however: It seems every other time I compile the project, a lot of drawables get corrupted, resources lose their ids (resulting in NPEs in the code), or classes throw "Verify Errors". The only way to fix this is by removing the bin and gen folders, and recompiling, which is obviously annoying. Is there any way to avoid this? btw, I'm using ant 1.7.1, java version "1.6.0_20"

  • The best way to refresh my .aspx site with a Timer in C#?

    - by radbyx
    I have a default.aspx page that needs to be refresh every 10 sec. My solution so far is a javascript function, but it only works in firefux and not IE. I'm looking for a way to handle the refresh mecanism in the default.aspx.cs page instead, with some sort of Timer. Any good simple sugestions/hints or solutions out there that can lead me in the right direction?

  • Boost Serialization Library upgrade

    - by Konstantin
    Hello! How do I know that I can safely upgrade Boost Serialization Library on a production system without breaking compatibility with the existing data ? Is there any test that I should perform in order to be sure that all data stored in the binary format by previous version of the library will be successfully read by the new one ? Does Boost Serialization library itself guarantee some sort of compatibility between versions ?
