I have a shared linux host account (and I occasionally help the admin with some installation stuff)
I currently host a few PHP sites on it like Dokuwiki, a few feedback forms, a mail image bug tester, piwik and a few others
Also I host a gemini server for my own site and a gemini chat server that I actually wrote myself in Java
a web2gemini gateway
a Misfin server (again wrote myself)
On a pubnix host I host a uptime kuma instance to check my main server
On a vps host I have an instance of Linkace that I wanted to try out but am not really using
