• Is it best practice to try - catch my entire PHP code, or be as specific as possible?

  - by Itay Moav

  I do not have many kinds of Exceptions in my project. Right now,(we use MVC) I have the try catch encompassing my entire code: try{ fronController::dispatch($somthing...); }catch(Exception $E){ //handle errors } I wonder if there is a good reason to use the try-catch block in as specific as possible way as I can or just keep it general as it is now?

  I'm programming a function for a TI-NSpire, so I can't use the builtins from inside a function. What is the most generally efficient algorithm for sorting a list of numbers without modifying the list itself? (recursion and list-splitting are fair game, as is general use of math.)

• How to process large block data visualization with Flex?

  - by hydra1983

  I know that's a big topic. However, it's better to know some general ideas to handle such problems. I have an application which requires Flex to render statistics data calculated instantly on the client side from a downloaded data set. The problems are: the data set is large and needs more than 10 seconds to be downloaded. there are some filters to control the statistics calculation algorithms. If user changes the filters, it would take a long time to recalculate the result and freeze the UI.

• Hyperlinks and iPad videos

  - by bhan

  Hello everybody, I'm trying to develop something in the cloud incorporating video, text and images. However, any hyperlinked content that appears above or below the video is unclickable, as the video takes the focus on the iPad. This isn't a problem with Safari in general, as it works on Desktop Safari. Thankyou, BH

• Eclipse vs Netbeans

  - by Zenzen

  Some time ago (~4-5months ago) I attented a lecture about JEE and at some point the lecturer started talking about webservices and how hard it is to create a good one because all the IDEs make them in a bit different way (or something like that) and that in general it's better to use Netbeans to create them as Eclipse has some issues, the thing is he didn't really say why Eclipse is bad. Now I'm wondering is what he said true and why, is it really better to use Netbeans for webservices and why?

• Redirecting exec output to a buffer or file

  - by devin

  I'm writing a C program where I fork(), exec(), and wait(). I'd like to take the output of the program I exec'ed to write it to file or buffer. For example, if I exec ls I want to write file1 file2 etc to buffer/file. I don't think there is a way to read stdout, so does that mean I have to use a pipe? Is there a general procedure here that I haven't been able to find?

• List of drugs for sample data

  - by Skoder

  Where can I find a list of common medical drugs? Researching and typing 150+ drug names would be quite inefficient. In general, are there any sites which have a list of items for developers to use in applications? For example, you can download dictionaries in specific formats (e.g. XML) for use in word games.

• How significant are JPA lazy loading performance benefits?

  - by Robert

  I understand that this is highly specific to the concrete application, but I'm just wondering what's the general opinion, or at least some personal experiences on the issue. I have an aversion towards the 'open session in view' pattern, so to avoid it, I'm thinking about simply fetching everything small eagerly, and using queries in the service layer to fetch larger stuff. Has anyone used this and regretted it? And is there maybe some elegant solution to lazy loading in the view layer that I'm not aware of?

• Unicode Regex; Invalid XML characters

  - by Ambush Commander

  The list of valid XML characters is well known, as defined by the spec it's: #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF] My question is whether or not it's possible to make a PCRE regular expression for this (or its inverse) without actually hard-coding the codepoints, by using Unicode general categories. An inverse might be something like [\p{Cc}\p{Cs}\p{Cn}], except that improperly covers linefeeds and tabs and misses some other invalid characters.
