How to change Pantheon Terminal's color scheme

Many of us spend many hours of our days using their terminal. Plus, we all have different tastes when it comes to color schemes. That's why the ability to change the color scheme of a terminal is one of its more important featuresl. Throughout this tutorial, I'll teach you how you can change the looks of your terminal, step by step.

sudo apt-get install dconf-tools

Secondly, you need to decide which theme you're going to apply. You can find dozens of terminal color schemes online, you can even design your own using this web application. Design the color scheme, hit "Get Scheme" and choose "Terminator". You'll get a raw text file with a background color, a foreground color and a palette. Those strings define your color scheme.

How to replace broken stock Ruby on OSX 10.10 (Build 14A238X) (developer release - 6/6/2014)

The stock version that comes with OS X 10.10 DP1 is know to to suffer following errors:

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/yaml.rb:4:in `<top (required)>':                                                                           
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.
