There's a lot to Ruby and even experienced Rubyists are sometimes surprised to learn about parts of the language they haven't encountered before.
Do you really know all of the syntax Ruby can read? Are you familiar with all of the methods provided in Ruby's core? Have you used all of the roughly 100 standard libraries?
In this talk, I'll dig into the extras of Ruby and see if I can't turn up some features that you don't see all of the time, but that might just be handy to know about anyway. I'll make sure you come out of this able to impress your friends at the hackfest.
