I've been a MRI committer since last Fall, and contributor to Sinatra, Shoes, and a few other projects for a few years.
This will be my time in Europe, and I'm very excited to see Greece!
Have you ever wondered what that ~20MB of code in your Ruby installation is there for? You didn't know Ruby came with a eso- standard library?! Well it totally does, and there's a lot of hidden gems in there just waiting for you to uncover.
Allow me to guide you through some of the more delightful members of the standard library. I will hand pick libraries authored by the pioneers of Ruby and show you the useful bits.
You'll discover a pure Ruby Markdown parser, practical configuration for the REPL, and distributed Ruby just to name a few.
