I would suggest a baikal server: https://sabre.io/baikal/docker-install/ it’s made from.the ones making radicle and sabre, one of the kost used open source caldav/carddav servers. Yes it can sync calendars too

yep: https://yunohost.org/#/

It’s technically possible, but windows doesn’t give you as the user tools to do so. If you donÄt want windos to have the ability to do so you could use full system encryption like: https://wiki.archlinux.org/title/Dm-crypt/Encrypting_an_entire_system

first just messing around with it, then starting selfhosting and then i started to dualboot just for fun, and one day i by mistake nuked my windows installation, so now i’m a full time linux user

you can do anything without ever using a desktop environment

okay basically so many things sooo much better, first of all i can change any part of software of the os for any other one i like. I can fix my installation no matter how broken it is as long as the filse system is still intact.

definitely some alternative internet mesh routing standart, just imagine if every device with wifi or ethernet could just extend the network without relying on an isp, yeah they could still serve as a fast backbone, but they just wouldn’t be needed and no disaster could really ever disrupt the whole internet again

honestly: activity pub, matrix, xmpp, markdown and soo many more probably. All of these would be able to solve our walled gardens problem, but the apps with a basically monopoly don’t have much of an incentivw to implement them

But it’s definitely possible to ship a virus embedded in a playable mkv file, but something else would have to extract it first, for it to do anything

if you really only played it and it didn’t abuse some zero day in vlc (extremely unlikely), the there’s basically zero chance you could have activated a virus.
