  • Is there an open source repository for SQL code?

    - by morpheous
    I find myself writing SQL code (queries or stored procs) to solve problems that can definitely be defined as 'patterns' that occur frequently in business. Rather than having to wrack my brain each time I encounter a new problem (which must have been solved a countless times by other coders/db analysts, I wondered if there was a repository I could go to check out (peer reviewed) code - and maybe add my two pence every now and then. I know different db vendors tend to write slightly variant forms of SQL - but there could still be a repository with ANSI stuff and proprietary stuff. Hopefully, such a site would encourage more people to write standardized SQL. Is there such a site?. If no - why not? (would anyone else be interested in such a site?) If such a site exists, please provide link(s), as Google is not finding anything remotely useful.

  • Redundant code constructs

    - by Diomidis Spinellis
    The most egregiously redundant code construct I often see involves using the code sequence if (condition) return true; else return false; instead of simply writing return (condition); I've seen this beginner error in all sorts of languages: from Pascal and C to PHP and Java. What other such constructs would you flag in a code review?

  • How can I avoid causing memory leaks in Firefox?

    - by mrdanimal
    It seems that there is a lot of information on memory leaks in IE and how web developers can avoid them, but I can't find much on avoiding leaks in FF. I've found lots of random tips on how end users can tweak their preferences, or tips for extension developers, but little on what I can do as a web developer to make sure my pages don't leak. Am I missing something? It seems lazy to just blame it on the user and say "you've got too many extensions". Or are the major patterns the same as in IE -- circular references and all that? Also, if anyone knows of any tools to troubleshoot leaks in FF, that would be great. I found this: https://addons.mozilla.org/en-US/firefox/addon/2490/ But it's apparently just for chrome and extension development.

  • Can a program have a few IFs and only one Else structures?

    - by kwokwai
    Hi all, When I was doing some JQuery and PHP, I noticed the If-else patterns were treated differently and varied from one language to another. Say I got a simple input text field in a HTML and I was using some Ifs and Elses to check the value input into the text field. Text: <input type="text" name="testing"/> In JQuery, I got some codes as follows: if($("#testing").val()==1){ //do something } if($("#testing").val()=="add"){ //do something } else{ //do something } if($("#testing").val()=="hello"){ //do something } How come JQuery and PHP treated the Else statement differently? I mean in JQuery, the third If statement was still proceeded even if it had gone to the Else statement, but it stopped after the Else statement when I repeated the code in PHP script.

  • Is it possible to cut down the size of Flex 4 deployments?

    - by Robusto
    My bin-release for a very simple Web project using Flex 4 is weighing in at 1.5MB. 40% of that is taken up by one single file which is over 600K all by itself. Here are the files that take up most of the volume: framework_4.0.0.14159.swz 608KB spark_4.0.0.14159.swz 311KB textLayout_1.0.0.595.swz 153KB There are others as well, but this is over a megabyte right there. All this was fine when I was writing components for a large Flex application, but now I need to do widgets on an HTML page using a CMS. Are all these files really necessary to deploy? Are there things I can do to cut down the weight?

  • Is the offical Sun Java EE tutorial the best way to learn how to make Java web apps?

    - by Nick
    I've been a web developer for almost a decade. I've mostly used classic ASP/JavaScript and I'd like to move into Java based apps. I have a decent understanding of Java itself (enough to know how to lookup what I don't know) and I spent some time doing minor work on a JSF/Spring/Hibernate app, but from what a trusted coworker told me, this application is the example of what not to do. I want to learn the really hardcore stuff (EJBs, HA Clustering, etc), but I know I have to walk before I can run. Is the Sun Tutorial the best place to start? Or is there an definitive book (like K&R for C or Gang of Four for design patterns) that I should buy?

  • why do you write tests and what is a unit test and how does it differ other types of testing ?

    - by dfafa
    im curious as to know, why tests are written? why would bother writing it ? why not just compile and run the code or view it in your browser, click around and test out stuff. i mean i can understand, a crawler that checks your web app's functions....but why is tests written, maintained and treated as important as the main feature codes ? is it crucial to always write and use tests ?

  • i = true and false in Ruby is true?

    - by alex
    Am I fundamentally misunderstanding Ruby here? I've been writing Ruby code for about 2 years now and just today stumbled on this... ruby-1.8.7-p249 > i = true and false => false ruby-1.8.7-p249 > i => true Could somebody explain what's going on here please? I'm sure it's to spec, but it just seems counter intuitive to me...

  • Delegates vs. events in Cocoa

    - by aaronstacy
    I'm writing my first iPhone app, and I've been exploring the design patterns in Cocoa and Objective-C. I come from a background of client-side web development, so I'm trying to wrap my head around delegates. Specifically, I don't see why delegate objects are needed instead of event handlers. For instance, when the user presses a button, it is handled with an event (UITouchUpInside), but when the user finishes inputting to a text box and closes it with the 'Done' button, the action is handled by calling a method on the text box's delegate (textFieldShouldReturn). Why use a delegate method instead of an event? I also notice this in the view controller with the viewDidLoad method. Why not just use events?

  • Javascript: How to detect if a word is highlighted

    - by fterh
    I'm writing a Firefox addon that is triggered whenever a word is highlighted. However I need a script that detects when a word is highlighted, and I'm stuck. An example would be nytimes.com (when you're reading an article and you highlight a word, the reference icon pops up). However the nytimes.com script is super complex. I'm 16 and not much of a programmer, so that is definitely way out of my league.

  • What is a good FAT file system for ARM7-TDMI

    - by Seidleroni
    I'm using the ARM7TDMI-S (NXP processor) and I need a file system capable of reading/writing to an SD card. There are so many available, what have people used and been happy with? One that requires the least amount of setup is best - so the less I have to do to get it started (i.e. write device drivers to NXP's hardware) the better.

  • Find all <a>s to who's href points to an image with XPath 1.0

    - by Jeffrey Aylesworth
    First, I can assume that all urls that end with jpeg, jpg, bmp, png or gif are images, and others aren't. I thought of, and tried two solutions: Matching the regular expression .(jpe?g|bmp|png|gif)$ Using ends-with to check each separately But, it appears that neither of these exist in XPath 1.0, or at least, they don't exist in Firefox (I am writing a greasemonkey script, so it is only important for the path to work in Firefox).

  • How can I determine if a file is read-only for my process on *nix?

    - by user109078
    Using the stat function, I can get the read/write permissions for: owner user other ...but this isn't what I want. I want to know the read/write permissions of a file for my process (i.e. the application I'm writing). The owner/user/other is only helpful if I know if my process is running as the owner/user/other of the file...so maybe that's the solution but I'm not sure of the steps to get there.

  • ASP.NET MVC image upload store location (db vs filesystem)

    - by adrin
    I am writing web application using ASP.NET MVC + NHibernate + Postres stack. I wonder if images uploaded should be stored in database as binary blobs or on filesystem (and reference only in db). One advantage of db storage I can think of is easy backup/recovery of all data without reverting to filesystem copy tools. On the other hand I suspect that filesystem access may be faster (but is it especially when dealing with many concurrent requests?) What are your suggestions?

  • Anchor Window to Screen Edges in WPF

    - by Kirk
    I've decided to teach myself C# by writing a music player in Visual Studio 2010. I went with WPF because from what I hear it sounds like it will be a good base to skin from. I want to program my window with the behavior where if the window comes to the edge of a screen (within 10px or so) it will snap to the screen edge. What's the best way to go about this?

  • What is the meaning of this C++ Error std::length_error

    - by Janusz
    While running my program I get this Error: terminate called after throwing an instance of 'std::length_error' what(): basic_string::_S_create Abort trap I know that you can't do much without the code but I think that error is to deep in the code to copy all of it. Maybe I can figure it out if I understand what this error means. Is this a sign for an issue with reading or writing at the wrong memory address? Is there something I can do to get more information about the problem from my program?

  • What is the fastest / best Base64 en/decoder for Java ?

    - by mP
    Just found the MIG Base 64 utility but its over 6 years old since its last release. It would appear to be quicker than the Apache commons equivalent but I have yet to confirm by writing up an actual test. Has anyone verified its correctness which is always a worry. If someone takes a look at the methods, please note i a referring to the non fast methods which make assumptions trading possible correctness for pure speed.
