Ruby is an open source, interpreted, object-oriented programming language created by Yukihiro Matsumoto, who chose the gemstone’s name to suggest 'a jewel of a language.' Ruby is designed to be simple, complete, extensible, and portable. Developed mostly on Linux, Ruby works across most platforms, such as most UNIX-based platforms, DOS, Windows, Macintosh, BeOS and OS/2, for example. According to proponents, Ruby’s simple syntax (partially inspired by Ada and Eiffel), makes it readable by anyone who is familiar with any modern programming language.
