Erlang made stupid simple for Ruby programmers

I started learning erlang with the very good and well written book by Joe Armstrong - Programming Erlang: Software for a Concurrent World . I am trying to keep a summary of what I am learning and so I started writing it as a little note. Doing so I noticed that I am able to squeeze a lot of pages into few lines and thought that someone else apart from me MIGHT also understand what I meant as I wrote it as if I was explaining Erlang to another Rubist. I hope I am right.
