Practical Object-Oriented Design in Ruby: An Agile Primer by Sandi Metz
3.0
In my humble opinion, this book's greatest strength lies in its advice to think first not of objects themselves and their responsibilities, but as actors and messages passed between them. Perhaps you already knew this; I didn't, and doing so has been a tremendous new tool in my arsenal to tackle problems. Seeing and defining public interfaces and abstractions has become a lot easier. It's become so much clearer now, it's like the idea just popped into my head.
Chapter 4: Creating Flexible Interfaces has been a joy. While reading it, I couldn't drop the book for the life of me. It just clicked at the time: this is what I'm reading this book for.
Why the 3-star? I'm gonna share another humble reader's opinion here: While I know this is a Ruby book, I guess it could have done without the obvious dynamic/weak typing bias, only to spend half the book later providing tips to prevent problems inherent in the typing system.
