Matthias Noback is the author of the Leanpub book Recipes for Decoupling. In this interview, Leanpub co-founder Len Epp talks with Matthias about what he’s been up to since he last appeared on the podcast over eight years ago, changes related to widespread use of the PHP programming language in that time, how the pandemic affected his consulting work and meetups, legacy code, his books, and at the end, they talk a little bit about his experience as a self-published author, specifically, a method he has developed for keeping programming books up to date, even as the technologies they’re about evolve.
