He makes a lot of these CS joke-things (and also a lot of genuinely interesting stuff!)
The paper came from 1975, when programmers generally knew assembly language and unix was starting to flourish.
The apple II for instance didn't have an ADD instruction.
I believe you had to do Clear Carry then add with carry.
You can kind of see how the two universes of thinking collide in this paper.
related, you can do things like this:
[ "$A" = "$B" ] || exit 1
[ "$A" = "$B" ] && echo "a equals b"
Did it? Then how come it has references to “diff --git”, “https://git.kernel.org ”, and “https://github.com/”?
diff --git a/src/exec.c b/src/exec.C
I’ll assume that you are in on the joke and I am not, however!
That doesn't stop me from laughing at the hack that it is :)
