Practical Object-Oriented Design in Ruby is about how to write object-oriented code. It was written by an everyday programmer and it explains object-oriented design (OOD) using realistic Ruby examples.
OOD is not a mysterious black art that’s impossible to understand, it’s just stuff you don’t yet know. POODR is a practical, readable, and understandable introduction to how OOD can lower your costs and improve your applications.
If your code is killing you and the joy is gone, POODR has the cure.

A note on pronunciation: Think pooder, as if you were a three year old attempting to say computer. Please don’t think anything else, though you may smile as you say it if you like.
