I use Steam + Proton in an LXC so I can share the graphics card among several other containers. It works quite well with streaming once I got it set up.
With Plex you can go to https://app.plex.tv from your work computer and steam from your browser. That said, if you can install software, Plexamp is a great way to listen to and rediscover your music.
Nostr gets rid of the notion of servers and admins. At a high level everyone on nostr owns their own account (no central instance). When you want to post something you send your content to a list of relays you choose.
Other people can choose what relays they want to subscribe to.
Relays can block people from subscribing or posting.
Everything is cryptographically secured so there is no way for someone to pretend to be you.
Lemmy is different where the instance admin has complete control. Admins can post as you and users cannot easily migrate to a different server.
If there is a vulnerability in the software, it’s entirely possible for a single attack to take everyone down. All the instances are known and easily discovered.
Advanced data protection is across your entire account, not per device. According to Apple’s documentation they rotate the keys locally on your devices and then delete them from their services so they no longer have a key to give.
Sounds like you need some more hobbies to throw at it. :-)
You could always inflate the numbers by giving it artificial load but I imagine that breaks a ToS somewhere.
