Finding some really good sources for game development on r/gamedev.
The Reddit community is huge! It's very nice to see a section of it devoted to games and people who are willing to share information and collaborate.
I recently found a link to Valve publication that are very indepth!
http://www.valvesoftware.com/publications.html
I also ran into a post on a 300+ page tutorial book that has quite a few big names behind it!

Hope they help someone out there! I know I'm going to be looking through them in the near future.
