So now I read #poodr and got excited again about design what is the next book I should read?
POODR is Practical Object Oriented Design in Ruby by Sandi Metz. It’s a fantastic book, which I would recommend to anyone working with an object oriented language, not just Ruby.
As I went through the list of replies I found myself bookmarking the various other recommendations and thought others might benefit from it. So here is the full list so far:
- Object Thinking by David West
- Confident Ruby by @avdi
- Implementation Patterns by Kent Beck
- Growing Object Oriented Software Guided By Tests by Steve Freeman and Nat Pryce
- Software Architecture for Developers
- SmallTalk Best Practice Patterns by Kent Beck
- Ruby Best Practice Patterns
- The Common Sense of Object Oriented Programming
- 10 Technical Papers Every Programmer Should Read (At Least Twice)
- Object Oriented Software Construction by Bertrand Meyer
- Design Patterns Explained: A New Perspective on Object Oriented Design by Alan Shalloway
I don’t think I’ve missed any frmo the conversation, but Twitter’s UI makes it very hard to tell.

Thank James, this is a really good list. I have also found in the past the Design Patterns Explained book to be really useful.
Thanks for starting an interesting twitter conversation.
I’m not familiar with that one. In fact the only patterns book I’ve read is the gang of four one. I will add it to the list.
