RubyMadScience is simple courseware designed by Noah Gibbs. Noah was frustrated by the normal "sign up for my mailing list, get emailed articles after a set number of days" interface as a teaching method, and put together a simple online site with links, videos, completion tracking and better email reminders.
He also wrote a blog series about making it, because why not?
That email list isn't the best way to teach a technical class, but it's still a fine choice for keeping up with Noah's latest work. Care to join?
