Kind of dojo about Git

• Create a repository and push it to Github
• Change some files and commit it
• Create two files and edit an existent file, add all to the index and make a commit only with one of the new files
• Create another branch (cool) and change files
• (Stash here we go!)
• Go to master branch and push the modifications
• Go back to cool branch, unstash, commit and push
• Put the commits on cool branch on master branch doing a merge

O que são essas coisas?

• RVM: gerenciador de versões de ruby. Porém o mais legal dele é facilitar a compilação.
• RubyGems: gerenciador de dependências entre Gems (biblioticas ruby). É o apt-get do Ruby.
• Rails 3: um gem (biblioteca) da linguagem Ruby
• MySQL: Sistema de gerenciamento de banco de dados usado no Redu
• SQLite: Sistema de gerenciamento de banco de dados portátil.

Instalação do Ruby 1.8/Rails 3 usando o RVM no Ubuntu
