Ruby Turns 30 Years Old; Celebrate with a Quine! — Thirty years ago in a chat room far, far away, the name ‘Ruby’ came into being for Matz’s then-nascent language. This milestone has been celebrated by many including Matt Sears, DHH, Charles Nutter, in a (Japanese) ▶️ audio message by Matz himself, and many others, but I had to feature this amazing effort to create a quine, of sorts, that works on “all currently known CRubys” (right back to Ruby 0.49!). It’s worth hitting “Translate to English” on this page to learn a few things about Ruby’s history.


In his ▶️ audio message, Matz acknowledges there are multiple ways you could define Ruby's birthday, but he's happy to go with the date it was named in this case.
