Crystal: Fast(er) Ruby

Ruby is attractive because of how expressive and fun it is to write, not because of its speed. Ruby gets the job done most of the time. However, what happens when you need that extra speed boost? Now you can reach for Crystal. Crystal is a compiled, statically-typed language with Ruby-like syntax. You'll have a chance to see how easy Crystal is to install, how it compares to Ruby, and a chance to see how to convert a Ruby script into Crystal.
