Ruby on Racetracks tutorials

[Jason Hsu, Ruby on High Speed Rails]

Check out my tutorials on much faster ways to get started in Ruby on Rails at http://www.rubyonracetracks.com/tutorials.html .  Thanks to Docker, you can have Ruby on Rails ready to roll in minutes, not hours.  Thanks to VirtualBox, you don't need to install Ruby on Rails in Windows or figure out how to make Bash scripts work in Windows.
