I had a bit of good luck this week. I found and attended a free Ruby Primer course given by Jeff Casimir of jumpstartlab. I've dabbled a bit in Ruby and the primer provided a wealth of new learning.
The course was excellent, both in content and presentation. Jeff's background in education and teaching gives him a unique style - he's engaging and knowledgeable. If you're in to Ruby/Rails, take a look at jumpstartlab's offerings.
