Oh you silly duck! Semafor is a common word in a handful of other languages for things like traffic lights and such. I had to do a double take when I first saw it in a programming class.

Also hope you’re doing well it’s been a minute since our paths crossed on gdnet.

"Semaphore" is (old) Greek and means "sign (sema) bearer (phore)", and actually the meaning in railways and computing is more or less the same: in computing, a semaphore signals if a resource is in use; in railways, the resource is a segment of a railway line, and the user is a train.

It does the same role in plain roads between pedestrians, cars and similar vehicles.
