The imitable Miles Sterrett, organizer of Indy.rb, co-organizer of Indy.js, guy that makes indyhackers.org, and general man about town, is organizing a Holiday Season thing for programmer types.
"...you'll see Pythonistas touching glasses with Java guys, Rubyists joking with the .NET-ers, COBOL gentlemen adjusting their bowler hats — everyone is more than welcome. The best part? It is completely free."
