    The other thing to keep in mind is that if you have a policy of considering 98% to be "close enough", then it only takes 35 of those decisions to remove over half the population. A…

    I’m not an expert here, but it sounds like you’re forcing a first-order logic problem into a propositional logic box. A “native” first-order logic solver like Z3 might be something…

    It's interesting to contrast "Measure. Don't tune for speed until you've measured" with Jeff Dean's "Latency Numbers Every Programmer Should Know" [0]. Dean is saying (implicitly) …

    (I'm not an expert. I'd love to be corrected by someone who actually knows.) Floating-point arithmetic is not associative. (A+B)+C does not necessarily equal A+(B+C), but you can g…

    There are two extremes here: first, the "architects" that this article rails against. Yes, it's frustrating when a highly-paid non-expert swoops in to offer unhelpful or impossible…

    Another point is that the world is always changing. If you work slowly, you are at much greater risk of having an end result that isn't useful anymore. (Like the author, of course,…

    I think that there are three relevant artifacts: the code, the specification, and the proof. I agree with the author that if you have the code (and, with an LLM, you do) and a spec…
