Since I’ve reached the part of my internship where I need to evaluate a Ruby web API client library and had never written Ruby, I went looking for places to learn! Some of these are books, some are websites, some are web tutorials. All are online and free. If you’re new to Ruby, give these a shot!

Ruby is definitely not what I am used to, but it seems like an interesting language and I’m looking forward to learning more of it when I have more time.
