  • 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?

  • MySQL: What's the best to use, Unix TimeStamp Or DATETIME

    - by Axel
    Hello, Probably many coders want to ask this question. it is What's the adventages of each one of those MySQL time formats. and which one you will prefer to use it in your apps. For me i use Unix timestamp because maybe i find it easy to convert & order records with it, and also because i never tried the DATETIME thing. but anyways i'm ready to change my mind if anyone tells me i'm wrong. Thanks

  • Does AutoSproc Scale Well?

    - by nickyt
    We use AutoSproc as our DAL, not my choice, but it was there when I started working at my job. I was wondering if any one had any experience using AutoSproc with large web applications? I'm just curious if it would scale well as our application is growing and we might need to pop it into a web farm at some point. If it doesn't scale well, what would you suggest then since there are several options out there. Any info is greatly appreciated.

Can anyone please explain what is a binary and how to create one? Thanks

  • How do I implement graphs and graph algorithms in a functional programming language?

    - by brad
    Basically, I know how to create graph data structures and use Dijkstra's algorithm in programming languages where side effects are allowed. Typically, graph algorithms use a structure to mark certain nodes as 'visited', but this has side effects, which I'm trying to avoid. I can think of one way to implement this in a functional language, but it basically requires passing around large amounts of state to different functions, and I'm wondering if there is a more space-efficient solution.

  • .NET / WPF Alternative

    - by eWolf
    I know the .NET framework and WPF pretty well, but I think the whole thing has gotten too blown up, especially for small apps as the whole .NET framework 3.5 weighs 197 MB by now. I am looking for a language/framework/library that provides functionality similar to that of WPF (animations, gradients, a.s.o.) and the .NET framework (of course not everything, but the basic features) and which is faster and more lightweight than the .NET framework and creates smaller and faster applications than the ones using .NET. Do you have any suggestions?

  • System call time out?

    - by Arnold
    Hi, I'm using unix system() calls to gunzip and gzip files. With very large files sometimes (i.e. on the cluster compute node) these get aborted, while other times (i.e. on the login nodes) they go through. Is there some soft limit on the time a system call may take? What else could it be?

  • Why does Java's hashCode() in String use 31 as a multiplier?

    - by jacobko
    In Java, the hash code for a String object is computed as s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1] using int arithmetic, where s[i] is the ith character of the string, n is the length of the string, and ^ indicates exponentiation. Why is 31 used as a multiplier? I understand that the multiplier should be a relatively large prime number. So why not 29, or 37, or even 97?

  • enabling the "return button" in a UITextField keyboard (objective-c/iphone)

    - by peter61
    When I start editing a UITextField, I have the "Clear When Editing Begins" option checked so it starts off with no text. However, the "Return" button is grayed out until you type at least one character. I've seen other iphone apps where the "Return" button is not grayed out (and if you press it with no text, then it goes back to what the text used to be). How is this done? Thanks.

  • ASP.NET Compiled vs Uncompiled DB qualifiers

    - by rlb.usa
    We have an ASP.NET application that uses SQL statements, where table names are unqualified. When compiled, it works fine, but when uncompiled, it complains and errors out, saying these tables dont' exist. (Qualified name looks like Select * from MyDatabase.mySchema.MyTable ; Unqualified like Select * from MyTable) If you try these queries on the database, by yourself, it will take only the qualified names. What's going on? I thought Compiled vs Uncompiled apps should perform the same way codewise.

  • New iPhone Dev policy...how does Apple enforce this? [closed]

    - by milesmeow
    Apple doesn't want anyone to create iPhone apps outside of the Xcode/Objective-C environment. How can they actually enforce this? If the non Xcode IDE, for example Unity, compiles to an iPhone executable, how will Apple know which dev environment you used to create the app? Can they have Xcode compile some sort of signature into the executable that no one knows about?

  • Javascript Mp3 Player, NONE FLASH

    - by Yo Momma
    I currently have a simple flash Mp3 player on my site which works lovely. The issue is, most cell phones do not support flash and a large portion of my visitors come through via a mobile device. The alternative to this is to replace the flash player with a javascript player. I found a JQuery one but it only works on HTML5 compatible browsers. Does anyone know of a good alternative that would work on mobile devices as well as most desktop web browsers?

  • A lightweight application framework for PHP?

    - by millenomi
    I have long been a fan of _why's Camping microframework -- lightweight, great for microscopic applications (low concurrency, easy to use and edit and maintain), which is what I do. I'd love to know if there's something similar for PHP; full-blown app frameworks like CakePHP or Symphony are very large for what I do, but I can't seem to find nothing "less". What PHP framework would you prefer, in this situation?

  • Can't sign into linkedin when using a QT4 (WebKit-based) browser?

    - by Inshim
    I started using the lightweight QT4 browser for some of the time on my Mac. Most simple websites, and even quite a few AJAX-heavy web apps, work for me flawlessly, including gmail (!) However, with LinkedIn, I can't even manage to sign in. Even when I change the useragent to one of a regular browser, it keeps kicking me out. Any ideas what could be wrong and for some workaround? Thanks!
