Just saw this one thanks to one of my readers. SitePoint is giving away a free Ruby on Rails book by Patrick Lenz on how to build your own web applications in Ruby on Rails. The book has 12 chapters and 447 pages. You can get the e-book for free, or a printed edition for a generous discount. I downloaded mine earlier. All you do is give them your email and they send you the link. Oh, it’s only free for another month from the time I am writing this. You can download it here.
