This is a defunct domain kept around by Adam Chlipala to preserve e-mail addresses and nostalgia.
It began life as a programming resource site (created in my teenaged years) that only took a few steps before collapsing.
Then, since it was lying around anyway, I used the domain as the name and home of the dynamic web site system that powered Teen Programmers Unite.
We used it as the default domain for our nascent hosting cooperative before it became The Internet Hosting Cooperative.
