    I feel like Jeff hawkins was working on this with HTMs, but they never really took off. I suspect it was hardware adaptability based, memory access patterns for sparse graph traini…

    I understand charge time is a concern, but it is'nt the theoretical limitation of really any battery technology. From the computing parlance it's embarrassingly parallel. More, sma…

    Do they mean deterministic k-means, k-means++ ... ? Global optimal k-means is NP-Hard, so linear speedups aren't terribly helpful. It's nice, until you add more input. Standard k-m…

    I've considered the move to wired not for quality but for the sad state that Bluetooth pairing headphones has become. Theycan't just be headphones anymore; They require their own a…

    probably a lot of economics going on, such as early age vendor lock-in, and new market acquisition loss-leaders, but ultimately it's not cutting edge hardware. So the same reason t…

    are you referring to this paper https://arxiv.org/abs/1501.01711 ? i believe they won best paper at icml or other impact journal. the published paper and algorithm i recall being c…

    i agree, not just the multinomial sampling that causes hallucinations. If that were the case, setting temp to 0 and just argmax over the logits would "solve" hallucinations. while …

    for an interesting reversal of the "problem" of the speed of light, IEX is a stock exchange design to combat HFT by adding a physical speed bump by way of 38 miles of fiber optic c…

    i agree, also add to that, that many python modules are foss projects that are maintained on a limited basis or budget. Refactoring code that may have some unsafe async routines wo…

    On the surface, cutting less essential resources during a power supply event makes sense, the ranking of essentialness seems problematic. While the decision to stop dumping megawat…

    I've used pbzip2 which takes the same parallel blocked compression approach 7zip seems to be taking (using AI's analysis of the changes). Theoretically the compression is less effi…

    It depends on what level of nuts you mean. Some are AGI skeptics about LLMs, theyre probably right, there is likely more breakthroughs required before true AGI. But AGI isn't requi…

    By defined format I of course don't mean random, or that it doesn't have structure, you have to be able to read it back otherwise what would be the point. I mean when you write out…
