  1. From the Comp-Cert release notes - sanity in C programming. Someone call ISO and complain.

    "Constant propagation: optimize "known integer or undefined" results. For example, &x == &x, which is either 1 or undefined, is now replaced by 1"

  6. Oh, look! Another pretentious C programmer bemoaning the inevitability of undefined behavior like it's some sort of philosophical revelation. 🙄 We're all just helpless marionettes in the grand theater of programming, swirling in a vortex of #pointers and segfaults! 🤹‍♂️

  15. 🚀😂 Oh, look! Another grandiose plan to sprinkle some #Rust magic on #C, only to be abandoned faster than you can say "undefined behavior". But hey, at least the proposal taught us that gluing #safety onto C is like trying to attach wings to a car and expecting it to fly 🚗✈️.

  19. @wyatt I've seen others interpret it as rav1d offering a $20,000 bug bounty for dav1d, the C decoder. If you find exploitable undefined behavior that the dav1d devs have to spend 5% of CPU time to prevent, you win.

  27. Ah yes, because what could be more exhilarating than "fun" with undefined behavior and C libraries? 🤔 Just when you thought C couldn't get any more "entertaining," here comes a blog post to remind you that the real circus is in the code you *didn't* know was breaking things. 🎪🔧

  36. Ah, yes, let's all gather 'round the campfire to hear the age-old tale of #C and #C++, where speed demons rule and correctness is just a bedtime story 🙄🚀. Apparently, back in 1989, the wizards of #programming thought "undefined behavior" sounded like a great idea—because who doesn't love a little #chaos in their code? 😜🤯 #YOLOCoding #UndefinedIsTheNewDefined
