• What is the best forum plug-in solution for the Symfony framework?

  - by Zoja

  I'm looking for a good solution to integrate a forum into a symfony application. Something like phpBB would be excellent. I've seen phpBB plugins to integrate with symfony but that's not enough for my purposes, also, mapping database tables is a lame approach in my opinion. If anybody knows a good working forum component for Symfony then I would really apreciate it. :) Thanks!

• Besides SO, what are the discussion boards and newsgroups you visit?

  - by Sapphire

  I think question says it all. For me, I know only one very good local discussion board (I'm from Bosnia), but none really good international ones... Stack Overflow is surely one of the greatest, but its style makes it great for asking questions, and only that. There are no discussions :/

• How to teach Django to non-web programmers? [closed]

  - by Greg

  I've been tasked with providing a workshop for my co-workers to teach them Django. They're all good programmers but they've never done any web programming. I was thinking to just go through the Django tutorial with them, but are there things in there that wouldn't make sense to non-web programmers? Do they need any kind of webdev background first? Any thoughts on a good way to provide the basics so that Django will make sense?

• UI Design Tips and Tutorials for Android

  - by Omega

  Does anyone have any good pointers on designing the UI for an android application and some good practises? Obviously I'm aware of the basic principles involved with designing the layout in XML. Also, that you have a stack of activities. But I'm interested in some approaches to creating the interfaces and also how to design an application around those intentions.

• Share your conky tips / scripts / .conkyrc

  - by Chad Birch

  I've just started tinkering with conky, and I'm hoping the StackOverflow crowd can share some of the cool things they've done with this tool. Scripts and .conkyrc files specifically geared towards developers would be especially good to see. Some good examples of developer-centric functions would be repository-monitors or heck, even something that monitors StackOverflow. Screenshots of what the functionality actually looks like would be appreciated as well.

• Preferred Options for Webservice to Android

  - by Tim Almond

  I need to get an Android app to interface with an XML webservice (it's really just a request which returns XML), but as the data is large and includes some things I don't need (like a huge description block), I was thinking of transforming it via a server into a format that would be good for Android, and also to be reduced considering it will be used in a low bandwidth area. Does anyone have any suggestions for a good lightweight protocol? I'm especially thinking about libraries for Android that already exist for say REST or even delimited data.

• PHP language specification ?

  - by Rolf

  Hi, as I know there is an official document for Java (JLS), I'd like to know if it's also the case of PHP language. I found the "Language Reference" section on the PHP manual, but it doesn't look as detailed as the JLS. The thing is I have a good practical knowledge of PHP but I'm miserably clueless about what REALLY happens under the hood. If there isn't any official document, could you recommend me some good books to read ? Thanks in advance ! Rolf

• Implement a server that receives and processes client request(cassandra as backend), Python or C++?

  - by Mickey Shine

  I am planning to build an inverted index searching system with cassandra as its storage backend. But I need some guidances to build a highly efficient searching daemon server. I know a web server written in Python called tornado, my questions are: Is Python a good choice for developing such kind of app? Is Nginx(or Sphinx) a good example that I can look inside to learn its architecture to implement a highly efficient server? Anything else I should learn to do this? Thank you~
