When browsing around today I saw quite a few sites talking about the Rails Best Practices presentation / talk that ihower did at the Kungfu RailsConf. Check it below, it really covers a lot of basic tips on how to clean up your code and follow some better Coding Practices.

Someone just released a gem that will analyze your code and check for “Best Practices” –  seems promising. Check it out at GitHub here: http://github.com/flyerhzm/rails_best_practices
