require 'mind'

You’re not without knowing that Rails 4 is about to kick in in a few days (weeks?), are you? In a recent hobby project of mine I tested out MongoDB, together with Mongoid (the ORM that comes in replacement of ActiveRecord for querying the MongoDB database) and other pretty cool stuff. As I had a great time using it I wanted to give it a try using the all new and shiny Rails 4 and Ruby 2.

You’re using the command line from time to time and you want to go further? You’re at the right place.
You’re going to learn new tricks, use them and improve your skills with the command line.

Ready? Go ahead.
