    Rails 4 Tutorial

    blog

    I’m still deep in Rails. The official documentation is okay but kind of bloated. Fortunately I stumbled on Kevin Skoglund’s Ruby on Rails 4 Essential Training Course on Lynda and it is fabulous. Plenty of small videos I can watch when I want to get educated on a specific topic. And it’s way easier to digest than the official’s guide. I recommend it!
