    Huge gains? What was the impact of this change, considering the only context that we have is that it was not important to the customer? Answer should be expressed in terms of cost,…

    > would an ML optimization loop have discovered transformers? I think that’s exactly the kind of problem this group is looking to solve. You make a compelling intuitive argument, b…

    So they’re watermarking requests according to your environment variables and maybe changing a string format if you’re in a certain time zone? Am I missing something here? Where’s t…

    I’m confused: is it just markdown files in git? Or does the hybrid graph+semantic layer matter? If the latter is true, the title is just clickbait right

    I tried semaglutide and while it was effective for losing weight, it made working out impossible (felt exhausted and very sick as soon as hr went up) and it made hangovers awful. I…

    I’ve seen loads of very bad/wrong code written by humans

    I agree in part, but I think AI does meaningfully make it harder for leadership to detect their bullshit.

    The author of stringzilla, Ash Vardanian, has a bunch of really cool talks/lectures/demos. Highly recommend checking him out if you like that kind of thing :)

    I don’t think OP’s point has anything to do with AI companions. The big benefit of moving compute to edge devices is to distribute the inference load on the grid. Powering and cool…

    My issue with this is that a simple design can set you up for failure if you don’t foresee and account for future requirements. Every abstraction adds some complexity. So maybe the…

    I am seeing this at my work right now. They are about to start using token consumption as _part_ of the performance review process. Obviously this is a coarse and problematic proxy…

    Very bad hire. I’ve gently said as much to my manager and skip. But for some reason hiring is hard and firing is hard, and we’re a small team, so I’ve been told to just lower my st…

    AI pull request descriptions are my current pet peeve. The ones I have seen are verbose and filled with meaningless fluff words (“optimized”, “performant” for what? In terms of wha…

    I burnt out helping a junior on my team for the past few months. It was just terribly obvious she was feeding my responses directly into a chatbot to fix instead of actually unders…

    I think this is well put. Cohesive philosophy, even if flawed, is a lot easier to work with than a patchwork of out-of-context “best practices” strewn together by an LLM

    Context management, plan mode versus agent mode, skills vs system prompt, all make a huge difference and all take some time to build intuition around. Not all that hard to learn, b…

    Strawman. It’s entirely possible for two things to be true at once: border laws are worth enforcing, and the current approach of flooding ICE with untrained goons explicitly target…

    You kinda can, just don’t make a Twitter account, don’t buy teslas, don’t use grok. Tell your friends

    The crux is in the “and it gets implemented” part. Teams have a limited bandwidth, so what gets implemented absolutely is a zero sum game, that’s why backlog prioritization exists.…

    > good work speaks for itself I disagree. Ideas don’t speak, and work doesn’t speak. People do. Being a 10x engineer isn’t just about having great ideas, it’s about having great im…

    Inviting a reporter from the Atlantic to your signal chat where you coordinate military plans has nothing to do with government being too big

    This is true. What are the implications of that?
