Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

My Raspberry Pis all netboot. I have a bunch of them around the house. Some play music, some play games, some are smart TVs. Because they all boot from the LAN, there's no card to wear out, and I can change what OS they boot into just by renaming a file. It's simple, but intensely useful.

What are they netbooting from? Presumably there's a root device somewhere?

Yes, a TrueNAS box running a TFTP server for /boot and NFS for root.

The server is discovered via DHCP.
