I suspect it comes from raising flags/signals (literally as one might run a flag up a flag pole?) to indicates CPU conditions, and then that terminology getting propagated from hw to sw.
- comex 1y agoI would have thought it came from the concept of 'raising an issue' or even 'raising a stink'.
- Findecanor 1y agoSounds plausuble. Some of the earliest exception handling systems did not have any semantic difference between CPU exceptions and software exceptions.
- devnullbrain 1y agoYou can still use SIGUSR1 and SIGUSR2 for it.

- reverendsteveii 1y agoidk because there are some circles in which boolean variables are called flags but I've never seen them referred to as being raised or unraised/lowered, only set and unset
- kps 1y ago… which could come from raising the voltage of a signal indicating a condition.
