We all know the sorts of questions that come up time and time and time and time again! Yet there is no FAQ with a collection of neat answers following the latest techniques and best practices. It's time to put one together! Consider this a way to answer all those questions once and for all. Basically post any questions you've seen multiple times and if you can the best possible answers to them. Don't forget things like global naming conventions, libraries and plugins, pitfalls, options etc. Also, some of the answers will just be links to existing tutorials bringing the good ones together in to one handy reference.

Some questions to get this started:

• Gates - HAS to be top of the list! Automatic, locked, button activated, command activated, rotating, sliding, lifting etc.
  
• File saving - INI files, LOG files (very different formats and uses), write caches...
  
• Colours.
  
• Streaming.
  
• Commands - (strcmp, dcmd, zcmd, y_commands, other), how to upgrade from one.
  
• SQL queries (MySQL and SQLite).

I'll say now, I'm working on something BIG to address part of this problem (might need help with some parts if anyone is interested).
