    Ask HN: Bose-Einstein Condensate Qubits

    As I understand it, Bose-Einstein condensates get more stable as they get larger. Why are quantum computer developers not making their qubits out of them?

    Starship cans are pathetically inadequate to support even a Mars base, never mind a Mars colony.

    Translating it back to C or C++ afterward, it would be equally as safe, and easier to deploy.

    Actually-Practical Orbital Solar Power

    It is common to make fun of orbital solar power projects, for good reasons. Management consulting companies love getting asked to analyze orbital solar, because they get to dust of…

    Curiously, though, we don't really know it is coded in DNA. Michael Levin has been discovering lately that biology is more complicated than we thought. His YT videos are mind-boggl…

    Strontium-90 has advantages. At density 2.6 vs 12, you can afford to loft more of it to compensate for its 28y half-life, and still come out ahead provided you can dispose of the e…

    Arrayed as a thin film on a substrate, you can use the kinetic energy of the alpha particles directly for thrust. The substrate will need to dissipate some heat from nuclei emitted…

    Those use strontium-90, which decays much faster than americium-241. That makes it hotter, at first, but its useful life is less. Being more than 4x less dense, you might carry eno…

    Which C compiler doesn't pack bitfields? Anything on x86 or ARM is bound by the ABI to pack in a standard and link-compatible way. Seems there would only be a problem on some propr…

    It is much worse than just the three extra test-and-branch operations, because they will be serialized through one ALU.

    The doesn't say whether the C-145As built in Poland for the US Air Force still had the fault, or the SkyTrucks built until 2019. We might guess that since the fault wasn't in the p…

    After scrutiny this seems to be "Coroutines and Effects" in, particularly, Rust.

    I always wonder which of these smaller sauropods are really just juveniles. Why don't we find any juveniles of the big ones?

    Doesn't say what it is or how it is imagined to work. Is there an assumption the dust is all negatively-charged? Or positively? Or mixed?

    Is the language statically-typed? If not, why not?

    People were navigating out of sight of land, and reached Australia tens of thousands of years before this. They might have reached North America, too. Anyway we know people got the…

    We know Australia was already occupied at least 40kya, and maybe 60kya, and they can only have got there by sailing out of sight of land, even when sea levels were at their lowest …

    The extension cords mentioned are all interior-to-interior. There is no magickal difference between an extension-cord wire and a like-gauge Romex wire. The former bends easier. The…
