• Regular expression (PCRE) for url matching

  - by zerkms

  The input: we get some plain text as input string and we have to highlighight all urls there with {url For some time i've used regex taken from http://flanders.co.nz/2009/11/08/a-good-url-regular-expression-repost/, which i modified several times, but it's built for another issue - to check whether the whole input string is an url or no. So, what regex do you use in such issues?

• Ruby 1.8.7 and RSPEC tutorial

  - by Ben Nelson

  I'm just diving into ruby development for a class assignment and the machines at my Uni have only got ruby 1.8.7 on them so I need to develop for that. I have found tutorials on the web for ruby = 1.9 and rspec that are really good but I haven't found anything for ruby 1.8.7 (I'm guessing it's pretty dated?). Does anyone have anything using rspec testing and has an indepth discussion on ruby 1.8.7 for me? I'd really appreciate it! Thanks!

• Any GUI libaray for iPhone & Andriod based on OpenGL ES?

  - by Jeff

  Since both iPhone and Android support OpenGL ES, is there any open source or commercial GUI library we can use for these two platforms? Or is it doable (or how difficult) to port an application from one to another platform? As I know, for iPhone only, libNUI (http://www.libnui.net) is a good choice (dynamic layout & mature), but it only provides GPL & commercial license. Any other open source tool similar with libNUI?

• How many keys are too many in memcached?

  - by jack

  I currently have about 650,000 items in memcached (430MB memory used) and the number is still increasing. It's expected to exceed 1,000,000 items before going flat. Current hit/miss ratio is 25:1 so the efficiency is pretty good. I just wanted to ask is one million items in memcached on single server too many? If no, how many is too many?

• What does the PHP configuration option "--prefix=PREFIX" do?

  - by Xeoncross

  I have heard that setting the --prefix=PREFIX option when compiling PHP on linux will allow you to have more than one install of PHP at a time without them clashing. (I think the default if this isn't set is /usr/local). However, I'm not sure what exactly it does or what a good setting to use is. Furthermore, I've also heard that setting it to something other than the default value might make some PHP extensions harder to install. ./configure --prefix=PREFIX ...

• What exactly does Panel.IsItemsHost do?

  - by Armentage

  I cannot find any good documentation for the Panel.IstItemsHost attached property. I see plenty of examples of people setting it on the ItemsContainer template for an ItemsControl, but the un-documentation over at MSDN does not explain why or what advantages setting property confers. I have build plenty of containers that do NOT set this property, but have not yet noticed any ill effects.
