Ruby Study Notes: TOC Core Ruby Programming Introduction InstallationWhat is Ruby? Ruby (programming language) Ruby was conceived on February 24, 1993. In a 1999 post to the ruby-talk mailing list, Ruby author Yukihiro Matsumoto describes some of his early ideas about the language:[10] Matsumoto describes the design of Ruby as being like a simple Lisp language at its core, with an object system like that of Smalltalk, blocks inspired by higher-order functions, and practical utility like that of Perl.[11] The name "Ruby" originated during an online chat session between Matsumoto and Keiju Ishitsuka on February 24, 1993, before any code had been written for the language.[12] Initially two names were proposed: "Coral" and "Ruby".
Matsumoto chose the latter in a later e-mail to Ishitsuka.[13] Matsumoto later noted a factor in choosing the name "Ruby" – it was the birthstone of one of his colleagues.[14][15] Ruby Programming Language.
