Learning a programming language can be hard and time consuming. You normally have to go through a bunch of tutorials, ask questions, read books… Ruby is no exception: there are plenty of resources out there about it, but it is often hard to find what you're looking for. So, as a weekend project, I decided to create a Ruby Compendium, a short book about the Ruby Ecosystem.
I guarantee that you will not be able to code in Ruby after reading this book. Yes, you read it right, this book is not about coding, it's about learning what's out there for you that can help you to learn how to program in Ruby. Information on Ruby implementations, versions, web sites, books, podcasts, a handful of Ruby gems to solve common problems… it's all in there.
The Ruby Compendium is available free of charge, under the terms of the Creative Commons Attribution-ShareAlike 3.0 Unported License, and you can help improving it! It was written using my very own Glyph Framework, and the entire source code is available on GitHub, for anyone to fork.
