.I had forgotten that this HTML was still being served here until @tychotithonus@infosec.exchange pointed it out. I suspect the site has not worked properly for years, because I removed all dynamic content from my website at least 6 years ago, and the webserver was configured to not execute anything, so there was no way you could have decoded.
In 2006, https://mj.ucw.cz/geek/ appeared.
Anyway, the Geek Code is sexist, hetero-normative, fat-phobic, and a bunch of other horrible things that our community thought was ok 30 years ago that clearly wasn't. I no longer recommend it these 30 years later.
