  • Are event handlers 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?

  • Android: getting thumbnails from specific location on sd card

    - by dykzei
    AFAIK accessing thumbnails for images via MediaStore.Images.Thumbnails would generate thumbnails at first attempt, and that's what i need to perform against specific location on sd card. The question is how to make valid URI to content under specific folder? All answers i can find use just MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI as uri to make managedQuery. And result of it is Cursor that points to all sdcard images, while none examples can be found on how to access only specific folder.

  • .Net 4.0 Memory-Mapped Files verses RDMS Storage

    - by Harry
    I'm interested in people's thoughts comparing storing data in a traditional SQL based Database or utilising a Memory-Mapped File such as the one in the new .Net 4.0 runtime. The data in question would be arrays of simple structures. Obvious pros and cons: SQL Database Pros Adhoc query support SQL Management Tools Schema changes (adding more columns and setting default values) Memory-Mapped Pros Lighter overhead? (this is an assumption on my part) Shareable between process threads Any others? Is it worth it for performance gains?

  • what does "dead beef" mean?

    - by Xi
    Hi there: What does the word "dead beef" mean? I read it from a interview question. It has something to do with ipv6. I figured it could be a random hex number used for examples, like "The quick brown fox jumps over the lazy dog". Is my understanding correct? Or it has more significant meaning? Thanks!

  • What was the most refreshingly honest non-technical comment you saw?

    - by DVK
    OK, so we all saw the lists of "funny" or "bad" comments. However, today, when maintaining an old stored procedure, I stumbled upon a comment which I couldn't classify other than "refreshingly brutally honest", left by a previous maintainer around a really freakish (both performance and readability-wise) page-long query: -- Feel free to optimize this if you can understand what it means So, in the first (and hopefully only) poll type question in my history of Stack Overflow, I'd like to hear some other "refreshingly brutally honest" code comments you encountered or written.

  • C# Resources - How to find actual language file in use?

    - by Chris Meek
    I have a number resx files as follows, Resources-es-ES.resx Resources-es.resx Resources.resx (english defaults) They are compiled into an assembly and I use them for localising my web pages by simply referring to Resources.Ok for example. My question is whether there is a way to find out the "rendered culture", e.g. if I come into the site with my CurrentUICulture set to "fr-fr" for example it will fall back to using the English resources and I'm wondering how to get that information to help me with some JavaScript localisation.

  • Mixing garbage collected framework with normal code

    - by shw
    I know my way around Objective-C and I have experience with garbage collection from .NET, although I never used it in objective-c. I write my code without using it. Now I'm thinkig about using one of the frameworks (Blocks) which is available as GC-only. My question is - can I still use the framework without any changes to my current non-GC code and without using GC myself?

  • Is it possible to use Boehm garbage collector only for the part of the program?

    - by bialix
    I've read article in LinuxJournal about Boehm-Demers-Weiser garbage collector library. I'm interesting to use it in my library instead of my own reference counting implementation. I have only one question: is it possible to use gc only for my shared library and still use malloc/free in the main application? I'm not quite understand how gc checks the heap so I'm worrying about performance of gc in that case and possible side effects.

  • What is the state of C99 support in major compilers / toolchains?

    - by pkh
    A response to a comment I made here made me stop and think: "I don't really know what the state of C99 support is." Wikipedia gives details for a few compilers, but I'm not familiar enough with C99 to know all the bits and pieces of the standard, so I'm looking for a gestalt overview answer to the question: What is the state of C99 support in major compilers / toolchains?
