Fedora

I have an old desktop PC running Fedora Workstation, which I use as a media server and secondary workstation.

SSH keys have, for a long time, been the preferred method of authentication when using Git with remote repositories.

For the last six years I have been using a backup product called SpiderOak One which puts a large focus on privacy - it even got a recommendation from Edward Snowden.

Gnome Boxes and Virtual Machine Manager are great tools for running virtual machines on Linux.
