All articles and discussions should be about the Ruby programming language and related frameworks and technologies like Rails, Hanami, Sinatra etc. Please also add the relevant library tags when making a post.

Questions are encouraged! Including the #help tag will make them easier to find.

Ruby is an open-source dynamic object-oriented interpreted language that combines the good bits from Perl, Smalltalk, and Lisp. It supports multiple programming paradigms including functional, object-oriented, and imperative.

Ruby was initially conceived on February 24, 1993, by Yukihiro Matsumoto ('Matz') and version 1.0 was released in 1996
