fertapric/rails3-mongoid-devise-omniauth Ruby on Rails Tutorial: Learn Rails by Example | Ruby on Rails 3 Tutorial book and screencasts | by Michael Hartl Michael Hartl Contents Foreword My former company (CD Baby) was one of the first to loudly switch to Ruby on Rails, and then even more loudly switch back to PHP (Google me to read about the drama). Though I’ve worked my way through many Rails books, this is the one that finally made me “get” it. The linear narrative is such a great format. Enjoy! Derek Sivers (sivers.org) Founder, CD Baby Acknowledgments The Ruby on Rails Tutorial owes a lot to my previous Rails book, RailsSpace, and hence to my coauthor Aurelius Prochazka. I’d like to acknowledge a long list of Rubyists who have taught and inspired me over the years: David Heinemeier Hansson, Yehuda Katz, Carl Lerche, Jeremy Kemper, Xavier Noria, Ryan Bates, Geoffrey Grosenbach, Peter Cooper, Matt Aimonetti, Gregg Pollack, Wayne E. About the author Michael Hartl is the author of the Ruby on Rails Tutorial, the leading introduction to web development with Ruby on Rails.

A Tale of Abort Traps (or Always Question Your Assumptions) August 24th, 2010 For a few months now, the bundler team has been getting intermittent reports of segfaults in C extensions that happen when using bundler with rvm. A cursory investigation revealed that the issue was that the C extensions were compiled for the wrong version of Ruby. For instance, we would get reports of segfaults in nokogiri when using Ruby 1.9 that resulted from the $GEM_HOME in Ruby 1.9 containing a .bundle file compiled for Ruby 1.8. I finally ran into the issue myself, on my own machine a couple days ago, and tracked it down, deep into the fires of Mount Doom. It Begins I usually use rvm for my day-to-day work, but I tend to not use gemsets unless I want a guaranteed clean environment for debugging something. I had switched to Ruby 1.9.2 (final, which had just come out), created a new gemset, and run bundle install on the project I was working on, which included thin in the Gemfile. Debugging Now that I had the bug on a physical machine, I started debugging. Postscript
