    We can assume these sort of comments are in the code of self-driving cars, or flight control systems, right?pic.twitter.com/VMXjrKLpKf

        @allspaw if there aren't comments like that, they are lying

        @allspaw no because those systems are pristine perfect gems. if there are any problems it's the pesky programmer/operator/human's fault

        @auxesis @allspaw “Illumos OS” doesn’t even exist, and could thus be argued to have reached enlightenment.

        @bdha @auxesis @allspaw Turns out that comment isn't from illumos, but sendmail (I had to check, I'm a NERD).pic.twitter.com/Tulo3I7b7n

      • @allspaw @mrb_bk that's easy to remedy—just remove all comments in a pre-commit hook.

      @allspaw So your #illumos example is actually sendmail: https://github.com/illumos/illumos-gate/blob/09f79f7c66b85f056db11f58210dc6182c9b1aef/usr/src/cmd/sendmail/src/usersmtp.c#L297-L303 … Not that we don't have plenty of dirty hacks, of course...

      @allspaw It's interesting that the Go one is basically about the compiler being too clever with an optimization (escape analysis here).

      @allspaw probably worse in control systems as failure is less accepted, hacks are probaby hidden 😕
