Other links
On the internet, most private websites have been eaten by commercialized communities. The internet I grew up with was a very different place. A place that was more free and not as gamified, not as ad-ridden, and not as commercialized as the current internet of fake news, lies, and propaganda. Here is a list of some of the remaining private sites. If you own a private website that may fit into my area of interest, hit me up and I may add you.
- Mathematische Basteleien contains some mathematical curiosities. This site was one of the many inspirations for me to study math.
- Ulm Security Sparrows are/were a bunch of computer security enthusiasts at my old university.
Only German
- c-turbines is the home of a crazy Swiss guy. Each time I visit his website I hope he has not killed himself yet.
