  • Why is this code's execution speed so different?

    - by Steve Watkins
    In Internet Explorer 7, this code executes consistently in 47 ms: function updateObjectValues() { $('.objects').html(12345678); // ~500 DIVs } however, this code executes consistently in 157 ms: function updateObjectValues() { $('.objects').html('12345678'); // ~500 DIVs } Passing a number is over 3x faster than a string. Why are these results so dramatically different? And, is there any way to help the performance of the string?

  • Why is Perl commonly used as CGI scripts?

    - by Michael Vasquez
    I plan to add a better search feature to my site, so I thought that I would write it in C and use the CGI as a means to access it. But it seems that Perl is the most popular language when it comes to CGI-based stuff. Why is that? Wouldn't it be faster programmed in C or machine code? What advantages, if any, are there to writing it in a scripting language? Thanks.

  • Why is FLT_MIN equal to zero?

    - by Nick Forge
    limits.h specifies limits for non-floating point math types, e.g. INT_MIN and INT_MAX. These values are the most negative and most positive values that you can represent using an int. In float.h, there are definitions for FLT_MIN and FLT_MAX. FLT_MAX is equal to a really large number, as you would expect, but why does FLT_MIN equal zero?

  • why doesn't everyone use RAD tools?

    - by Sorskoot
    RAD tools like Clarion and WinDev claim to be 10x to 20x times faster in development and users of these tools claim the same. If that is thru, why are there so few people using these tools? if an application is made in 40 hours instead of 400 you would make a lot more money, right?

  • How to figure out why .NET app runs at 32-bit on a 64-bit machine

    - by user54064
    I have a .NET app (webforms - .NET 3.5) that is running on a 64-bit server as 32-bit (I checked the IntPtr.Size result). The compilation is set to AnyCPU so I would expect that on a 64-bit machine, the app would be run at 64-bit. There are many Third-party programs incorporated into the app, could they be causing a problem? How do I figure out why 64-bit compilation is not being done?

    Hi, I'm using jqTouch. Trying to figure out why when the scene / div change, it just change abruptly without the slide animation? Here is the setting that I have now: var jQT = new $.jQTouch({ slideSelector: '.link', useAnimations: true }); Again the scene change works just fine, just that I don't see the slide animation. What am I missing? Thanks, Tee

  • Why do garbage collectors freeze execution?

    - by Martin
    I was thinking about garbage collection on the way home, and I began wondering, why does the garbage collector totally freeze execution of a program? Personally I would have designed it to block any threads which try to allocate a new object, but threads which were running would be left alone. I can't imagine any situation where this would be a problem compared to how a garbage collector currently works.

  • Why is this <p> expanding the whole page?

    - by George Edison
    If you visit this page and shrink your browser window, you will see my problem. [If you want to open the page in a new window, just hold down shift when you click the link.] The answers to the question extend beyond the page margin instead of wrapping. I have spent the last half hour working with Chrome's Inspector and Firefox's DOM inspector - all to no avail. I just cannot figure out why it's doing this.
