This week on Cloud Out Loud find out why José Valim, Rails core team member and author of the Pragmatic Programmers book [_Crafting Rails Applications_](http://plataformatec.com.br/crafting-rails-applications/) might have a career in singing if he ever quits writing kick ass Ruby code. We discuss his work on Rails as part of Google's Summer of Code and get his advice on getting involved with open source. He also shares effective techniques for presenting at OSS conferences. We'll be offering a *$@#&*( huge discount on __Crafting Rails Applications_ in an upcoming R(*)TFM, so don't miss out. Get on the email list. Get on the twitterz. Get the discount when it drops.
