Japanese Rubyists you have not met yet

This document introduces two important Japanese Rubyists, Yugui and Itojun. Yugui was the release manager for Ruby 1.9 and wrote a Japanese edition book on learning Ruby. Itojun contributed the IPv6 protocol stack for Ruby and helped with the early development and release of Ruby by providing mailing lists and FTP access to Matz. Unfortunately, Itojun passed away in 2007 but his contributions to Ruby and as a free software evangelist in Japan remain important. The document concludes that while some Rubyists may not be met in person, their work can still be experienced through projects like Ruby and that the open nature of free software allows developers and communities to form around the world.
