    Cool, but I find rather than just shapes and indexes, tensors with labels are much easier to use and reason about. E.g.: { {user:bob, movie:"Heat"}:0.1, {user:alice, movie:"Frozen"…

    This brings back good memories from when a friend made C in nynorsk: https://www.pvv.ntnu.no/~andreer/nynorsk/

    I was able to get part way some years ago by demodulating the bitstream with gnuradio and then making small changes (like replacing one note with the next higher one) and noting th…

    I couldn't help but laugh out loud at the notion of a "held-out test set" for addition of 10-digit numbers.

    No, not beyond what I already put in the twitter thread. I wanted to wait until I had some cool distributed software running on it too, but then I ran into trouble with the plan 9 …

    Wanted to reply to you directly also to increase the chance you see this because I think I had exactly the same intrusive thought as you, and actually built such a cluster recently…

    I recently built a Plan 9 cluster of 8 raspberry pi zero (2w). From my supplier (digikey) the 2W was the same price and has 4X the cores! I think it looks quite cool: https://x.com…

    Yes, but it turns out it doesn't matter much. What _does_ matter is the huge reduction in the much more dangerous brake dust, as electric vehicles convert the kinetic energy back t…

    Same experience in Norway. 95%+ of new cars sold are electric. I've been riding my bike to work along the same road for 15 years. I used to have to hold my breath along some sectio…

    For use in retrieval/RAG, an emerging paradigm is to not parse the PDF at all. By using a multi-modal foundation model, you convert visual representations ("screenshots") of the pd…

    Sounds a little like this recent paper; "RAPTOR: Recursive Abstractive Processing for Tree-Organized Retrieval" https://arxiv.org/abs/2401.18059

    Analysis by dhruv___anand in https://twitter.com/dhruv___anand/status/1752641057278550199 suggests that there are three different "resolutions" in the embeddings, for the first 512…

    You can turn this into a pocket "lisp machine" by following the instructions on http://www.ulisp.com/show?4JAO - although I don't think this can make use of the LoRa interface (yet…

    I've been lucky to get to work through a few of these already, they do give a decent introduction in how to use Vespa tensor expressions. I believe it's one of the most flexible wa…

    Sorry to have caused you pain! I thought this video would get maybe 100 view at most, or I would have put more effort into it (like implemented paren matching in the editor first).…

    Comment #35077685

    Yes, I'd love some help with it, or it would probably take me years. Schematics and stls (made in tinkercad) will be coming once I find the time. For now I'm spending too much time…

    No, I did spend some time reading eink datasheets but in the end it seemed too hard for me to do on my own. There's the Kindle and Freewrite so it seems possible

    Comment #35077472

    Yes, I'm running the display SPI at 2MHz which is ~25 fps. Overclocking it to twice as fast works just fine but uses significantly more power as expected. I did not try to go furth…

    More RAM, a higher resolution display, a proper keyboard, solar power and much easier to program (for me at least). But yes, it is essentially the same sort of thing, and much more…

    Using the FPU I believe but quite inefficiently, most cycles are probably spent in integer operations and chasing linked lists for the lisp parser. http://forum.ulisp.com/t/barnsle…

    Comment #35077256

    Thank you! Yes, I've had this in mind for a while, I have some pictures of beginning the first prototyping by dismembering the keyboard back in 2020, although what I was thinking a…

    Comment #35077151

    Yeah, matching pretty well the advertised 5mW. But uLisp is probably not using the CPU very efficiently and so not driving it to the max that could perhaps be seen with something l…

    Yes, it's nearly always in active mode now. I haven't done much to use the sleep modes at all, only "sleep until next keyboard interrupt" when the program calls (get-key). Measurem…
