Here I found a funny note:
"Brian has been programming with Ruby since BR (before-Rails), which means practically since the dark ages. He has worked with several companies doing web development with Rails. In December 2006 he began contributing to Rubinius, launching the effort to write executable specs for Ruby. He is now employed by Engine Yard to work full-time on Rubinius."
Have you practice Ruby in since the dark ages?
Rubinius is an awesome and unique project. I will create a posting about it :)
