This started when I wrote a Bash script to do what this does. It used dc for math, the standard
set of commands, and the dunst notification daemon.
The new one still uses dunst, but now all calculation, file IO, sleeping, etc. are all handled via
libc and assembly code.
The code is not pretty, but it for sure works. Not everything is tested (its unusual for my laptop to actually be unplugged, but it happens), but at least some of the functions are tested and based on that I believe that all of it should work properly.
As with all my projects, why not? I have a 4 day weekend with labor day and no other major projects on the schedule.
