Rails Tutorial Holiday Discount

Dec 19, 2010 • posted by Michael Hartl

I'm pleased to announce the Rails Tutorial Holiday Discount! The coupon code


will get you 15% off any combination of Ruby on Rails Tutorial products. Act fast, though—this offer expires as soon as Santa Claus and Rudolph the Ruby-Nosed Reindeer are done with their work, which I estimate will be at 3 a.m. PST on December 25. (Tragically, right now northpole.com appears to use Microsoft Active Server Pages. Someday, maybe we'll manage to get Santa on Rails! :-)

Michael Hartl

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.)
