Created by Yukihiro “Matz” Matsumoto and first released (as version 0.95) in 1995, Ruby didn’t become massively popular until a decade later, when the Ruby on Rails web application framework was written. Today the language boasts an enormous global online community and powers everything from NASA simulations and the Metasploit security framework to Google SketchUp’s macro scripting API and web applications like Basecamp and A List Apart.
