Part one: Understanding Ruby

Meta programming, who hasn’t heard of it these days? You see it everywhere, you perhaps do so your self without even knowing. But what exactly is this thing called Metaprogramming.

Hell, it’s probably even hotter then your sister hottest girlfriend and that other girlfriend .. well you catch my drift! But in all seriousness it’s somewhat makes Ruby the awesome programming language as it is. But before we can actually use metaprogramming in language, you must understand the very basics of how Ruby works.

So you want to try ruby 1.9 and rails 3? Awesome! You’ve come to the right place. Before installing ruby 1.9 or rails 3 you want to install RVM (Ruby Version Manager). RVM is a handy tool which allows you to have multiple version of Ruby installed on your system (along with gems, which include Rails).
