Ruby on Rails – Free Ebook
Sitepoint is giving away (for 60 days) a free PDF copy of their Build Your Own Ruby on Rails Web Applications – by Patrick Lenz , (2nd edition). I bought the paper version of the 1st edition, and I like it: useful and easy to read. Despite I don’t use RoR, the book was usefull to understand some things in Symfony.
So why are you waiting for? Go get your copy!
