Design Patterns: Ruby and Ruby on Rails

I am creating a new page on my blog, regarding Ruby and Ruby on Rails Design Patterns links.

Regarding Ruby Design patterns, there are (in my opinion) 2 major resources: The “Ruby Design Patterns” book of Russ Olsen and the Ruby Best Practices Blog. The Design page is about the rest of them :).

A first link: a slideshow regarding common design patterns (Observer, Decorator, Factory, Command) implemented both in Java and Ruby. Enjoy.
