Be More Productive with Better Sublime Snippets for Ruby!

Long time readers of this blog will remember that I used to tweak GNOME’s gedit editor a lot. However, I ditched it for Sublime Text and I am not looking back. Here are some of the things I like about Sublime:

This article describes when to use which of Ruby’s randomness methods.
