I recently put together several detailed tutorials along with application templates that generate Rails starter apps using Devise, OmniAuth, RSpec, Cucumber, plus options for jQuery, Haml, etc. I loaded them up to my GitHub account and initially I was surprised at how many people were expressing appreciation and encouraging me to do more. Now I think I realize, it's not easy for many people to keep up with the ever-evolving Rails habitat. There's really a need for guidance that goes beyond the good intro tutorials and shows the steps need to assemble the pieces for real-world projects.
Here's a link to my GitHub account with the various example apps and tutorials:
