Ruby Association
Yukihiro "Matz" Matsumoto is the creator of the recently popular Ruby language. He started development of Ruby in 1993, so it's actually as old as Java. Now he works for Network Applied Communication Laboratory Inc. (NaCl, also known as netlab.jp) which has sponsored Ruby development since 1997. He also serves as a chairman of the Ruby Association, a non-profit organization focused on supporting Ruby. Since his real name is too long to remember and is difficult for non-Japanese speakers to pronounce correctly, he uses the nickname Matz on the Net.
