This is the sort of quirky fun that characterized the early days of UNIX and computing in general. It's refreshing to see the BSD community keeping it alive and well.
Yes. It is this spirit that got me excited about computers. It's impressive that OpenBSD has remained consistent all these years. One of my all time favorite projects.
As much as I find less practical use for OpenBSD these days, I'm very glad it exists, both for fun and whimsical things like this and for some cutting-edge security research and implementation which actually works in a practical way.
I am pretty sure these songs turned me into a die-hard OpenBSD fan back in the day. I remember first hearing of one on Slashdot at like 1 in the morning, and immediately shook my roommate awake to listen to it. He was not pleased. I thought it was good though.
