New beginning

Well it finally ended. Graduated from the MBA in Finances so now I'm able to go back and do what I like the most which is writing code and trying on new technologies. I moved the site to a proper content management system which in this case it is Drupal.

Did a minor update on the book code since Amazon moved their webservices from ECS 3.0 to 4.0 and it broke all my code, now it is fixed.
