    I did look at the skills file but I still don't understand how it can possibly pull from my other interactions. Is that skill file loaded for every one of my interactions with Clau…

    Could someone explain to me how this works? When I run an agent, I don't normally leave it running. I ask Cursor or Claude a question, it runs for a few minutes, and then I move on…

    Agreed. But these things have a way of not working out, and one the sadness, one forgets to celebrate the intermediate victories. I wanted to share an intermediate victory before r…

    thanks for the explanation! sorry i had misread the AI summary on "semiseparable". i need to firm my intuition on this first before i can say anything clever, but i agree it's wort…

    fair. thanks. i'll sleep on it and update the paper if it still sounds right tomorrow. probably my nomenclature bias is that i started this project as a way to find new preconditio…

    just to be clear, semiseparate in this context means H = D + CC', where D is block diagonal and C is tall & skinny? If so, it would be nice if this were the case, because you could…

    Good q. The method computes Hessian-inverse on a batch. When people say "Newton's method" they're often thinking H^{-1} g, where both the Hessian and the gradient g are on the full…

    Show HN: The Hessian of tall-skinny networks is easy to invert

    It turns out the inverse of the Hessian of a deep net is easy to apply to a vector. Doing this naively takes cubically many operations in the number of layers (so impractical), but…

    It's neat to see an attempt at writing a compiler in Python without using a compiler toolkit and without writing it in Haskell. But also, I think you're running past some of the ha…

    I doubt an LLM would have written this: # Parameter in Stack-Slots laden (für MVP: nur Register-Args) # Semantic Analyzer markiert Params mit is_param=True # Wir müssen jetzt die f…

    One of the three rules on the page do not apply to either Persian or Urdu. The article “Al” isn’t used in them, so the third rule doesn’t apply.

    sorry, yes, you mention in another comment the use case of multiple readers operating on different versions of the db simultaneously. that'd be difficult to do with git for the rea…

    don't you get the same benefit if you version controlled the db file with git? with git, each commit saves a diff from the previous one as a blob. the difference is that in git, in…

    It sounds like you're in an average FAANG team. You could try switching teams. Here's why I think you might be in an average team: >"I have tried over the past 2 years to propose d…

    Thanks for making it crisp. This argument was in the article, but somehow it wasn't popping at me.

    Comment #32207273

    could someone explain the benefit of storing energy as natural gas? once you burn it, doesn't it result in co2? doesn't that defeat the effort? also is natural gas really easier to…

    I’m not getting the problem Anthony is trying to solve. I get that people are trying to keep him at bay, but what is he trying to do that they don’t want him to do? I get that he’s…

    You’re right. A whistleblower has to report illegal activity, and that’s not what the petition does. My phrasing is bad.

    I’m not suggesting it. I’m merely clarifying what he wrote. Did I misunderstand what he’d written in his tweet?

    Brian, you have legitimate points. Here are my edits to your tweets to help people receive them better (i've tried to not change the message, just the tone): """ I’m deeply trouble…

    Also to mention soda’s kernel was patched to kprint() a rootcow at boot, before even the network driver was loaded. Dedication to style.

    The article is fun to read, but I’m not convinced C’s lack of generics prevents it from supporting fast generic sort. Imagine qsort() being a header library, and a compiler that ca…

    the matrix example is a good example of latex being too verbose for its markdown host. \underbrace and \begin{cases} are two others ones that seems antithetical to markdown. and ma…

    for what it's worth, i was grateful to be called out on my gender assumption. that assumption can cause widespread harm. i'm less concerned about my pronoun assumption.
