    Crime is legal (if you're in the right group).

    It's only a fraction of the effect (and of course there was also over financialization), but 20% of the US population was farm labor in the 20s, that fell substantially (and there …

    I worked on the early iPod scroll wheel, before there were advertisements for it and it was in common use. I found the UI interaction odd and unintuitive, particularly the "menu" b…

    Yes, I set a calendar notification then. Don't mind the dup, though.

    The solution to pollution is dilution. It might not always be true, but it is here.

    Longer to write and generally a numerical rather than symbolic representation.

    Yeah, bra-ket is arbitrary tensors (inner and outer multiplication) rather than the nice 4D of space-time (with derivatives). I will say that seeing transformers written this way g…

    bra-ket is the (most?) general form of tensor manipulation. Raising and lowering operators for summation notation are the beginner tools for covariant derivatives of the metric ten…

    Yeah, came here to say this. There are a lot of things that will affect efficiency and how clean your panels are is only one of them. How dirty your panels get is also highly sensi…

    Yes, I'm agreeing with you. There need to be 200 companies willing to pay $10B/yr for this. What is the ROI? That's the pay roll of ~half the work force of the largest 200 companie…

    That sounds reasonable, it's "just" $1k/yr for 2B workers (there are about 1.2B total "knowledge workers" in the world including gig drivers), or $10k/yr for 200M workers (there ar…

    Asking the right questions has almost always been one of if not the most important skills. There are often an almost infinite list of possible approaches, but knowing the domain, y…

    Ask Claude to choose a set of improvements that it would rate highly.

    I don't know any Jain well, but I believe they drink milk and fermentation products, but do not consume honey. Open to correction.

    I think it's often called ovo-lacto vegetarian. There are also pescetarians.

    Hindu drink milk and eat cheese, butter, and honey. Not vegan.

    Worse than? What has been done to Ye? I mean, he's known for being a nazi symp and hitler lover, but that's just facts. Should we forgive Hitler too, because he was neurodivergent?…

    How is this not labeled (2022)? It sure hasn't aged well. The oppression of billionaires and owners of the media by the few non-bots left on social media is kinda hilarious. The id…

    I think there were big reflectors in the book, but it's been years since I read it. It's the sail that would need to be toroidal and huge. I guess the better point is that, if you …

    It is more similar to the Medusa method. Lots of ideas have been proposed. One problem is getting the nukes prepositioned (and they won't easily stay in one spot!) with chemical ro…

    This is really being driven by tandem OLED with blue phosphorescent (not fluorescent which is the current commercial design) layers, most likely from Universal Display Corp. The bl…

    Well, there is a way to do it slowly, the probe(s) just need to be in a 500AU circular orbit. At that distance power and thrust are an issue, and RTGs seem like a better choice tha…

    I'm a bit skeptical of the token cost/ROI for all models, but sunk costs are sunk. It has the feel of self-improving super-intelligence or bust to me. If you get that, the frontier…

    Part of the reason is that they used NiMH for the batteries in those (I have 3 that are 20-30 years old some predating the Phillips logo). All of mine still work. The NiMH is good …
