People love Nix because of the OS configuration based around a single config file. Essentially, you define your system configuration in this file, including installed programs, then you rebuild your system based on that configuration.

The beauty here is that you can easily move this file to another machine running NixOS and reproduce your configuration there. You can also roll back changes by simply rebooting and choosing the last known good build and you’re back in business.

I would look into Tailscale. This would probably be the easiest to setup.

I used to host a ton of stuff, now I just host my WordPress site on Linode.

I have toyed with the idea of selfhosting a Lemmy server, but that’s a project for another day.
