Setting up and installing rbenv, ruby-build, rubies, rbenv-gemset, and bundler

This guide enables you to install (ruby-build) and use (rbenv) multiple versions of ruby, isolate project gems (gemsets and/or bundler), and automatically use appropriate combinations of rubies and gems.

TL;DR Demo

# Ensure system is in ship-shape.

aptitude install git zsh libssl-dev zlib1g-dev libreadline-dev libyaml-dev

CodeKata: The Bowling Game

The game consists of 10 frames as shown above. In each frame the player has two opportunities to knock down 10 pins. The score for the frame is the total number of pins knocked down, plus bonuses for strikes and spares.

A spare is when the player knocks down all 10 pins in two tries. The bonus for that frame is the number of pins knocked down by the next roll. So in frame 3 above, the score is 10 (the total number knocked down) plus a bonus of 5 (the number of pins knocked down on the next roll.)

A strike is when the player knocks down all 10 pins on his first try. The bonus for that frame is the value of the next two balls rolled.

Refactoring Tips

When you find you have to add a feature to a program, and the program's code is not structured in a convenient way to add the feature, first refactor the program to make it easy to add the feature, then add the feature.
Before you start refactoring, check that you have a solid suite of tests. These test must be self-checking
Refactoring changes the programs in small steps. If you make a mistake, it is easy to find the bug.
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.

The mock_auth configuration allows you to set per-provider (or default) authentication hashes to return during integration testing. You can set it like so:

 OmniAuth.config.mock_auth[:facebook] = {
    'user_info' => {
      'name' => 'Mario Brothers',
      'image' => '',
 'email' =&gt; '[email protected]' },

The mock_auth configuration allows you to set per-provider (or default) authentication hashes to return during integration testing. You can set it like so:

OmniAuth.config.mock_auth[:twitter] = OmniAuth::AuthHash.new({
  :provider => 'twitter',
  :uid => '123545'
  # etc.
})

You can set the :default key to return a hash for providers that haven't been specified. Once you set the mock auth hash and turn on test mode, all requests to OmniAuth will return an auth hash from the mock.

The mock_auth configuration allows you to set per-provider (or default) authentication hashes to return during integration testing. You can set it like so:

  OmniAuth.configure do |config|
    config.test_mode = true
    config.add_mock(:default, {
      :info => {
                  :email => '[email protected]',
                  :name => 'foo',
 :password =&gt; 'qwerty123',
