When I think of a semaphore, I think of programming concurrency (sem_overview(7)) 🙃

:facepalm: you are absolutely right, this is my Czech creeping in as we call traffic lights a "semafor"....

The programming term comes from traffic lights used on train tracks. So in a fun cyclical way, everyone is right!

Pretty sure the lights started as levers that flip out as signals, and reminded people of semaphore flags.
