Facebook Application Development: Are there Tutorials, Screencasts, etc. that are Architecture Centric

Are there any good tutorials that outline proven Architecture patterns for Facebooks applications开发者_如何转开发? Most of the resources I've found in their development documentation are hello world oriented. I'm looking for something (article, book, screencast, etc) that outlines common things that a Facebook application will do, and common, proven , repeatable ways of accomplishing that.

Thanks!
