Selfhosting is a recent hobby of mine that has soon become an obsession. It started with torrenting and hosting Jellyfin for media streaming, moved me to build my own server, then expanded to learning to be a home "sysadmin."
Selfhosting is easier than you can imagine, provides safety in backups, tons of services, and privacy in services.

I include this in its own category because it contains a series of social media services.
The core service I host is Lemmy, a Reddit-like service.
