What is Ruby?

Ruby is a fairly young programming language, conceived in 1993 and first publicly released in 1995. It was created by Japanese programmer Yukihiro “Matz” Matsumoto. And if you're running OS X you already have Ruby installed. Yup, it's already there waiting for you. For more historical info see “Ruby (Programming Language)” on Wikipedia. Ruby gained significant popularity with the rise of Ruby on Rails. (Rails is a web application framework written in Ruby.) In fact, web searches for things having to do with Ruby will usually land you on a page that's specifically discussing the Rails framework. But Ruby is good for more than just building Web sites. We're about to make a spinning cube with it, right there on your Desktop!
