Haha, as the author of that commit, I'm embarrassed to see it here. Maybe it's a story, though.

I heard about Heroku Bartender from http://devopsweekly.com

It pushed me to finally use a Linode slice for which I had a $60 credit from http://appsumo.com and play with Ubuntu, which is outside my typical skill set.

I had fun installing Ruby, git, Postgres, and https://github.com/defunkt/cijoe on that slice. While stuff was installing, I added the favicon to Heroku Bartender.

There's a lot of cool software and tools out there. Open source, DevOps Weekly, etc are awesome for learning and playing.
