Two of my students are keenly interested in Ruby on Rails so I'm encouraging them to follow that path. Installing Rails on Ubuntu is a pain, though, quite confusing for a newbie like me. Good thing there's Turnkey Rails, a prepackaged LiveCD of Apache, MySQL, and Rails.
Turnkey Rails is a relatively light download, only 173MB. I installed it in a VirtualBox virtual machine. Fortuitous, too, that the VirtualBox I'm using -- version 2.1.0 on x86 -- already has host interface support without the headache of previous versions. It means I can access the Turnkey Rails guest machine's services from my main web browser.
