    If you want the library to perform that selection, you also need the "correct" / most efficient implementation to be independent of your workload. I'm not that familiar with SIMD p…

    > There is no reason a portable_simd relu_dot implemention should need to specify the SIMD width. What should it choose then? I have a Zen 3 processor, and benchmarking some simd I…

    It's been a while, but I believe Windows initialises an internal thread pool & parallelises (some parts of) process start / module loading

    If you're only taking one float as input, we've long been at a point where you can just test them all: https://randomascii.wordpress.com/2014/01/27/theres-only-fou...

    Long term projects that survived on short term wins are still around. But you're going to want to check how big the graveyard is of "project collapsed under tech debt from short te…

    Does it satisfy 98% of users always? Or does it satisfy each user 98% of the time?

    It's interesting to consider that the same question would've surely come up during C and C++ language development, but that the answer is informed by the impact on the ecosystem, w…

    Do you also oppose drivers licensing, alcohol age limits? Those rely on a trusted ID managed by a government.

    I expect it's referring to the newtype pattern; you don't want to accidentally add inches to cm, so if you have to handle both of them a lot, you make a single field struct Inches …

    Bugs due to cache state are absurd. In the classical sense of the word. When Bruce Dawson investigated a bug in the Xbox 360 cpu, the offending instructions didn't even need to "ex…

    For a more mathematically rigorous treatment, negative feedback is fundamental to Control Theory; it allows us to stabilise processes that would otherwise go out of control.

    I'll take a punt; based on the last pairing, where "statefulness" is abandoned > You could have multiple independent, divergent copies of the state but not a single consistent stat…

    I took some time to think about why this saying bugs me, and I think I've settled on "it suggests you can't understand your limits". I know it's explaining the joke, but you've blo…

    Agreed on the last point. I'm very much in favour of developing an analysis that can assert the absence of an abort, I just can't see how an approach like Fil-C can achieve that. I…

    > Regarding the silly point: Fil-C is less of a rock than Safe Rust as everything in C just works. I'm going to challenge this. Is this from your experience? InvisiCaps, which Fil-…

    Very explicitly making a silly point; a rock is 100% memory safe. The serious point: I care about whether the program I write aborts regularly, whether due to a Rust panic or a cap…

    It's also not a law of nature that there be a valid/efficient form of a product that makes a business profitable. I'm in no place to judge whether that's the case here, but not all…

    I didn't have budgets handy, but GDP is another way to normalise its cost to the country; ~$2.2B cost in 1942 with a nominal GDP of $166B, nominal GDP of $29.2T in 2024 puts the Ma…

    Why are there exceptions in the first place then? If that's what you want, write ON ERROR RESUME NEXT and be honest about it.
