I was lamenting the use of "semaphore" but wikipedia supports them: > Semaphore (lit. 'apparatus for signalling'; from Ancient Greek σῆμα (sêma) 'mark, sign, token', and Greek -φόρος (-phóros) 'bearer, carrier')[1] is the use of an apparatus to create a visual signal transmitted over distance. https://en.m.wikipedia.org/wiki/Semaphore I was only familiar with: > [A semaphore] is a variable or abstract data type used…

The Portuguese and Spanish word for it, semáforo, is what traffic lights are called at least in parts of Latin America.

I always interpreted the programming meaning as that - traffic lights.

And the programming semaphore comes from the semaphore used as train signal to ensure that two trains are not using the same track segment simultaneously.

Semaphores are also used on shooting ranges.

It is the same in Italian (semaforo).

I wonder if there are any good keyboards that are part of trousers, but that are also hidden, you know not immediately obvious that you've got a keyboard on your trousers. Then you could have a computer in the pocket or a bag and a HUD! That could be very cool!

You can integrate 30% or smaller wireless keyboard (with Elite-C) in your trousers IMHO. This would address "good" part (think something like this https://www.tzcl.me/blog/rae-dux but without PCB and wired using wires). At least I use adux keyboard of similar size daily. Or you can go even smaller with something like this https://artsey.io/ but I am not sure if this could be considered good. Next part would be concealing it - kailh low profile are too high IMHO for pants. There are switches that are even lower but most probably this might not work. I guess captive touch sensors might be solution but I am not sure if they would work well as keyboard. I guess some art would help concealing as well.

Still I don't feel this would be really comfortable to type on.

And also in Italy (semaforo) and I think in Romania (semafor)
