I'm currently going through Destroy All Software's screencasts [0]. They're heavily based on Ruby + Rails and TDD, although most of the concepts probably do do translate to other languages.
Since the screencasts are over 10 years old now, I'm wondering if Ruby on Rails is still going strong. What resources would you recommend to get into Ruby/Rails specifically? Same question for TDD? Thanks!
