    But assembly _is_ outdated, at least for the purpose of authoring large community software projects.

    I want to create software that doesn’t harm users. That doesn’t at all imply that I’m not interested in computers. In fact guaranteeing safety for users shows a profound interest in computers.

    All programming languages are syntactic sugar around processor instructions

  The design of io_uring has nothing to do with the language the Linux kernel is implemented in. And safer languages really can't provide guarantees when the issue at hand is designing a shared memory cross-executable (kernel⋄userspace) API.

    Just having first class slice types, where your pointer is paired with a length, which allows for doing bounds checking automatically is a huge upgrade over C, even if it doesn't solve every other problem. Security exploits from out of bounds access should not be happening today, bounds checking is a solved problem, and has been solved for decades.

      Time to make the point that not even C authors were able to change WG14 mind on the necessity of having fat pointers. https://www.bell-labs.com/usr/dmr/www/vararray.pdf https://www.bell-labs.com/usr/dmr/www/vararray.pdf

        That's a pretty interesting paper. Thanks for sharing it. I wonder why Dennis Ritchie, with the weight his name carries, wasn't able to push it into mainstream implementation...

        Because once a language is managed by ISO, that doesn't matter, the author gets one vote like everyone else. So this shows how the majority of WG14 members see security in C.
