Codecademy is expanding its catalogue of free, interactive programming tutorials with the launch of five Ruby courses.
The New York-based startup has also brought its Python track out of beta and added two new courses on top of the original six it released this summer.
In response to user feedback about its Python program, Codecademy has also "entirely rebuilt" its site architecture for backend courses, co-founder Zach Sims told Mashable in an e-mail. Site visitors should find things faster and more reliable going forward, Sims said.
