For episode 23, we sit down with programming veteran and Ruby expert Sandi Metz to discuss her new book: Practical Object-Oriented Design in Ruby! But we don't just talk about design patterns; we tackle everything from what Sandi means by "object-oriented design", to how design patterns permeate both software engineering and operations. We also philosophize on the art of the programming craft and what changes Sandi has seen over thirty years. Sit down with us for a conversation on: Practical Object OO (and Cat!) Design with Sandi Metz!
