Medical device engineer here (mechanical engineering). I host jellyfin, game servers (Minecraft, factorio, valheim, etc), my website, and a bunch of other minor services I find useful.
I got into it originally through a combination of poor internet, and being fed up with Google and others discontinuing products/features. The internet problem is solved now, so my only goal is not being reliant on someone else’s cloud.
I can read it because I’m tailgating them in city traffic on my bicycle.
