    It's so wild to have a whole paper about this... that's also LLM written. What are we even doing here?

    what were your favorite projects?

    The whole thing is unbelievable slop ! I think the whole article is llm-generated unfortunately (just reading the first paragraph I got an immediate smell).

    ha, thank you! it's very fun to write these hopefully you also enjoy the next one which imo makes a fun connection between the linear algebraic CRT and the fourier transform :)

    yes, definitely some of it is (purposefully) fast and loose, though (ideally!) mostly unambiguous with reasonable assumptions I think that part should've been "vector subspaces" ra…

    Fair on all accounts! Surely, this could be made way more lively if I were in front of a blackboard waving my hands and drawing images, but alas, the medium is what it is :) Thanks…

    well, the statement is: is there a single operation, built from elementary operations, such that all _other_ elementary operations have finite representations. this preprint answer…

    I think the point is that it is _finite_. if you allow infinite expressions then the basic monomial basis or quotients thereof are “even simpler”

    I don't think this can do any of the "standard" constants or what we generally consider to be closed-form expressions, though ! (E.g., no e, pi, exp, log, etc.)

    yeah it’s slop; multiple sites also confirm this, seems like they are using clawdbot or whatever

    > True, but with such numbers you will normally not do anything else except computing an approximate value of them. That's what I think people do with other numbers like "pi" at th…

    I don't want to put OP on blast here, but this is unfortunately just complete slop writing. The points being made are fine, I think, but look, if it's faster for you to generate th…

    Sweet thanks! Yes definitely a great extension would be to add a camera in the image plane (alternatively, defocusing the image slightly and using a photodiode would also be fun!)

    it is thoroughly _fine_ advice stated in a shitty way that misses the entire point of this cheap demo

    ah very cool, I see! good luck! are you posting updates anywhere?

    sure ! I’ll give it a try a little later once I’m at a computer ! (you can too, if you’d like, the CAD files are all online as .step files :)

    Ooh, great question. Usually fractions (~1/20th?) of a turn for alignment, it’s hard to go below that since the mounts are so small and the springs don’t have the tension to keep i…
