    In short, simplify the design to make it more reasonable for multiple implementations to agree while also adding intentional extensibility points and a governance model that allows…

    Comment #49233881

    I'm working on an improved Markdown that offers a simplified language, clear hooks for extensibility, and a governance model to let it grow over time.

    An assert statement requires that you specifically come up with a test case. Lean lets you verify for all possible cases . Infinity is not a problem. It's similar to a type system …

    Without having any opinion on whether or not the Bun team was meaningfully fuzzing their codebase... Andrew's claim was not about whether or not they were, it was noting that the s…

    It's also a language of distancing from personal experience and honesty. Not saying you're wrong. Professionalism is an important tool for maintaining professional relationships. L…

    I think you've got it. You go in each day and work on things and talk with people working on things. There are multiple opportunities to share weekly, one or two are pretty regular…

    I'm working on an easy-to-embed typed language called Ekto. I am taking a lot of inspiration from Koka and aiming to support full multi-shot delimited continuations all while keepi…

    I was asking questions about compiler techniques. Then when I got annoyed I started asking about experimental design. Both were very frustrating experiences once I started realizin…

    Comment #47977958

    All my usage of Grok for technical topics shows it regularly deeply misunderstanding things and just parroting back my question in fancy language. It’s the only frontier model I ge…

    I think, yes, with greater splat density—and, critically, more and better inputs to train on, others have stated that these performances were captured with 56 RealSense D455fs—then…

    Gaussian splatting is a way to record 3-dimensional video. You capture a scene from many angles simultaneously and then combine all of those into a single representation. Ideally, …

    Definitely not common! Nice to hear I'm not alone either. And yeah, I agree. Practically, it's the thing that annoys me the most day-to-day. I've mostly got wrapping set up to hand…

    I've recently begun replacing Markdown with Gemini's .gmi/gemtext format. It is Markdown with fewer features. I appreciate the simplicity and it's tremendously easy for custom tool…

    SDFs still scale by geometry complexity, though. It costs instructions to evaluate each SDF component. You could still use something like BvH (or Matt Keeter’s interval arithmetic …

    Genuine question, how does SPIR-V compare with CUDA? Why is SPIR-V in a trench coat less desirable? What is it about Metal that makes it SPIR-V in a trench coat (assuming that's wh…

    At the same time, if you want to use Claude to read the source and narrate how it works to you that’s trivial to do as a user.

    Comment #44490787

    If you're familiar with Zorn's Lemma, the construction is just to order bases by inclusion and to consider chains created by noting that there must be an independent dimension and …

    Comment #44457984

    Yeah, that's correct. You also often see it as having that for any method `X -> T ` there's a corresponding method `T -> T `. Or you can have that for any two arrows `X -> T ` and …

    Comment #44450039

    Every monad is also an applicative and liftA2 does/is the same thing as liftM2. The only reason they both exist was due to Monad being popularized in Haskell earlier than Applicati…

    Comment #44449498

    Monad tutorials are on the rise again. Let's start with function composition. We know that for any two types A and B we can consider functions from A to B, written A -> B. We can a…

    Comment #44447360

    The more constrained your theory is, the fewer models you have of it and also the more structure you can exploit. Monads, I think, offer enough structure in that we can exploit thi…

    Comment #44310854

    I’m not a huge fan of these, but this time I noticed that the best ones feel a lot like naturality arguments. As in, moving structural bits in a way that makes it clear that we’re …

    Comment #44273297

    Often it's easy to construct a family of sets representing something of interest. For example, we like to define integration initially as a finite process of breaking the integrand…

    Comment #44147094

    The quantification over T is still kind of weird, though. In a formulation like `for all T, (T and P consistent and T and neg P consistent)` is trivially false, just take `T = {neg…

    Yeah, I agree. "Independence" is fundamentally a property of the formal system you're working within (or really, it's a property of the system you're using and of the axiomatic sys…
