Chapter 12 is out, the Rails 2.3.8 tutorial is complete

May 26, 2010 • posted by Michael Hartl

I've just released Chapter 12: Following users, thus completing the Rails 2.3.8 version of the Ruby on Rails Tutorial. (Of course, this chapter is only a draft; as usual, I appreciate feedback and corrections.) I will soon be turning my attention to the Rails 3 version of the book, as well as starting work on the associated Ruby on Rails Tutorial screencast series. Finally, I expect to be making a special announcement some time in the next couple weeks, so stay tuned. (If you haven't done so already, subscribe to the news feed to make sure you get it. :-)

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.)
