Another teacher here, I picked up an interest in computing in general from my dad when I was young (got my start on an old C64). As I grew up we both discovered Linux and it’s been a slow burn ever since. My first self-hosted service was Emby and a simple file server, followed by a personal Moodle instance. I eventually moved to Proxmox for hosting my services and have steadily expanded my list as I become ever more dismayed by cloud hosted services and subscriptions.
