He was asking about Ruby on Rails and after I'd replied to his question, I emailed him asking him about a Rails-based class he mentioned teaching.
Oddly enough, turns out that I know him, but by a different last name. He's somebody I remember going to college with, and once saw randomly, briefly at a Gaskell's. His name was then Todd Turco, in case anybody here knew him. He's teaching for the Master of Software Engineering stuff at CMU-SV.
Small world. Always nice to know that people I remember are doing well.
