A simple question to this community, what are you self-hosting? It's probably fun to hear from each-other what services we are running.
Please mention at least the service (e.g. e-mail) and the software (e.g. postfix). Extra bonus points for also mentioning the OS and/or hardware (e.g. Linux Distribution, raspberry pi, etc) you are running on.
I am running a Ryzen 5700x with 48GB of RAM. I use it as my always on desktop/gaming computer/server running Gentoo Linux. The few services I use are:
Pihole
NFS (File sharing between my *nix computers)
Netatalk (AFP File sharing between my PowerPC macs)
Samba (Media sharing to an old laptop running LibreElec)
It's not a lot but it makes everything so much easier.
