Rails Tutorial & Rails 3.1

Jun 23, 2011 • posted by Michael Hartl

As part of the effort to keep the Ruby on Rails Tutorial up-to-date with the latest version of Rails, I am pleased to announce the availability of a special new chapter on Rails 3.1 (which is currently available as a release candidate). You can find the new Ruby on Rails 3.1 tutorial chapter online here.

The Rails Tutorial PDF has also been updated, and I have produced an accompanying Rails 3.1 screencast, which is now included with the purchase of the full screencast series or PDF/screencast bundle. (Everyone who already bought the PDF or screencast series should check their inboxes for a free update. The download pages have been updated as well, so you can also search for "Your Ruby on Rails Tutorial purchase" in your email client.)

A future edition of the Rails Tutorial book and screencast series will of course use Rails 3.1 (or its successor) from the start. Look for an announcement later this year.

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.)
