Toot

The fun thing about skimming the unsafe rust bugtracker is that, aside from wondering how any computer ever works at all, you pick up some fun compsci terms.

Today's term: demonic non-determinism, which describes a program that resolves all non-deterministic execution steps in favor of not halting. Contrast with angelic non-determinism, which given a choice always prefers to halt.

My new canon for Doom is that the future facility on Mars which opens a portal to hell turns out to be a miri extension that got out of hand.

Again if this sounds like I'm making fun of rust and its opsem efforts, I'm really not. I'm glad they're doing the thing, and I'm amazed that we seemingly got this far on what seems like quite shaky ground.

But otoh when I come across a bug that starts with "why is const?" followed by an long intricate discussion that loses me in the first paragraph, I can't help but feel like I'm going mad.

@danderson which gives clear insight into compsci biases, angels die, but demons live forever

@danderson this is also prophetic accuracy if we consider some bugs to be demonic - as noted earlier in your thread, the x86 bug has many demonic tendencies, and may never die, especially while still allowed to team up with c++ semantics which are most certainly very demonic
