Ever wonder which international border is closest? This map divides Germany into 9 zones, showing the nearest neighbor for any given point. Germany borders more European countries than any other nation.*

Federalism is a powerful obstacle to fascism, and if fascism were *already here*, federalism would not be around. Gavin Newsom would be spoken of in whispers as "that guy who did a funny thing once making fun of the Leader and then no one saw again."

For such a useful tool, Tailscale are bizarrely quiet about `tailscale file`.
`tailscale file cp filename.ext machine:` - on macOS, file lands in the target machine's Downloads folder.
No faff. No public keys. Whoosh pop.
And don't get me started about `tailscale serve` and `tailscale funnel`.

From a systems design view, it trades storage savings for coupling and complexity.
