I'll start. Did you know you can run a headless version of JD2 on a raspberry pi? It's not the greatest thing in the world, but sometimes its nice to throw a bunch of links in there and go to sleep.
Dang, that'd be cool. Didn't even know that was a thing. Probably before my time on the internet. Mostly got connected in the late 2000s and haven't ever heard that was a thing.
