Bowling centers (and restaurant PoS) as predecessors to modern infra is interesting in general.

I bet if you did a deep dive into Micros or Aloha POS at restaurants you could find similar opportunities for the rpi (and piss off an Oracle rep).

I love how this write-up started with acronyms I don't know, and ended with React and websockets, bringing it back home!

Sometimes I wish I inherited a farm, or auto shop, or something (bowling alley) so I could tinker on large scale, useful solutions using modern tech like this. Keep messing around you might land on a major, major innovation that the whole world uses.
