My instructors have been from Region Skåne the last few years, maybe they’ve been taught different things.

I have to do CPR training once per year, and almost every time they’ve changed the recommendations. I don’t even remember the current recommendations now.

I like the TeX version scheme, it starts with version 3. After that it’s:
3.1
3.14
3.141
3.1415 etc. Current stable release is 3.141592653. The message is that each version is a more accurate approximation of pi. It’s not growing much bigger, but better.

What if someone created a /c/books on their own instance with bad intentions, and filled it with propaganda, porn, and ads?

Maybe theology is discussions about OpenBSD founder Theo de Raadt.
