A full draft of the Ruby on Rails Tutorial, 2nd Edition, is now available

Feb 8, 2012 • posted by Michael Hartl

A full draft of the Ruby on Rails Tutorial, 2nd Edition, is now available. This draft includes previously unreleased versions of Chapter 10, "User microposts", and Chapter 11, "Following users". (As noted in the original announcement, the new edition has eleven chapters, whereas the first edition had twelve, with a bonus Chapter 13 on Rails 3.1. Since the new edition is based on Rails 3.2, the bonus chapter is superfluous, and the new has_secure_password method allowed further consolidation from twelve chapters down to eleven.)

I'd like to thank again all the readers who have reached out with suggestions and bug reports. Please keep them coming. Once people have had time to read the newly released chapters, I plan to incorporate new feedback and then begin offering PDF sales of the new edition, which should happen within a few weeks. I also plan to start producing the new screencast series shortly. As noted before, these new products will be paid upgrades, but current customers will receive coupon codes good for substantial discounts. For answers to other Frequently Asked Questions, please see the FAQ in the original announcement.

I’m Michael Hartl—author, educator, and entrepreneur. I’m probably best known as the creator of the Ruby on Rails Tutorial, a book and screencast series that together constitute one of the leading introductions to web development. Once called his “favorite book” by Wikipedia founder Jimmy Wales, the Ruby on Rails Tutorial currently has over 150 5-star reviews at Amazon. I’m also (in)famous for creating Tau Day and The Tau Manifesto, which have inspired an international movement dedicated to the proposition that “pi is wrong.” (For example, as a result of The Tau Manifesto, MIT releases their admissions decisions each year at “Tau Time” (6:28 p.m.), and typing tau/2 at Google yields 3.14159…) Finally, I’m a founder of Softcover, a publishing system and sales platform for technical authors, which among other things powers both The Tau Manifesto and the Ruby on Rails Tutorial.

I’m a graduate of Harvard College and have a Ph.D. in Physics from Caltech, where I studied black hole dynamics and was an award-winning instructor in theoretical and computational physics. I’m also an alumnus of Y Combinator, the entrepreneur program that has produced companies such as Dropbox and Airbnb. (Alas, my own Y Combinator startup was neither Dropbox nor Airbnb.)
