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/#/

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

yunohost it's basically an os that easily lets you selfhost, by having an extremely big amount of selfhosted services packaged with scripts that autonatically set everything up and all of that trough a clear and modern web interface.

yesss i love to find even more projects

yes, it and email are probably the two most widespread ones, i didn't include it because it's already pretty known

I'm kinda sad that theres almost no new work being made on top of it, seems even more promising than yggdrasil in some aspects

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.

It's far (really far) from perfect, but it's an example of the type of media we need, inspiring,. moving and hopeful for the future and technology, and it criticizes hopelessness and the "it's not bad enough to care about"-mindset

trying to advocate for sustainability, social justice, privacy etc. via my local and federal school councils, which have (even if it is quite limited) political power. And running some workshops for folks wanting to move to open source software.
