If you are a dev, or involved in any part of the software development process, do read "The Cathedral and the Bazaar"

It's really good,  gives an insight into how open source development really works and parallels it to how big tech teams create projects. 

 Is a book? 

 Yes, it's a book which is a collection of articles. Some by Linus Torvalds the guy that created linux 

 I'll look at it thanks 👌
