  • Computational-Fluid-Dynamics simulations are RAM-limited, iirc.

    I’m presuming many AI models are, too, since some of them require stupendous amounts of RAM, which no non-server machine would have.

    “diminishing returns” is what Intel’s “beloved” Celeron garbage was pushing.

    When I ran Memtest86+ ( or the other version, don’t remember ), & saw how insanely slow RAM was, compared with L2 or L3 cache, & then discovered how incredible the machine-upgrade going from SATA to NVMe was…

    Get the fastest NVMe & RAM you can: it puts your CPU where it should have been, all along, and that difference between a “normal” build vs an effective build is the misframing the whole industry has been establishing, for decades.

  • The amount of power you could pull from a single square metre of solar on the roof wouldn’t increase your range meaningfully.

    What it would do, is that you could possibly keep your starter-battery from going dead-flat if you left your car alone for a 1/2 month, in the summer ( snow would cover it, obviously ), & since bringing a lead-acid battery to dead-flat permanently-damages it, this would prevent costly problems for the car-owners.

    ( this happened to a friend with a Prius: had to replace the battery, and the damned thing was inside the rear wheel-well??? in a little compartment.

    Origami-engineering’s … simultaneously incredible & stupidly-frustrating )

    I’ve held for years that they should be doing it to keep the starter-battery trickle-charging, but … why make the customers have fewer costly/frustrating problems?

    Realistically, it’ll take 2 decades to hammer-out AI to the level that it’s truly-mission-trustworthy.

    Right now, everybody’s “high”.

    It’s the same with all technologies…

    Remember a few years ago, when somegody discovered you could power things with steam?

    Remember the hype?

    The whole coal industry, remember that?

    The business with the invention of the horseless carriages?

    The invention of the wheel was before my time, but I’m sure it was hyped on Myspace or something, back in the day…





  • Power-consumption.

    Also, the vibration produced by the 2.5" drives is less, but they’re more-sensitive to it, to begin with.

    I’d not even consider spinning-platter drives, nowadays, though:

    SATA SSD’s for a NAS strike me as being the sanest choice.

    Samsung what are those called, Evo drives?

    excellently-high MTBF, ultra-short ( compared with rotating-platters ) seek-time ( literally orders-of-magnitude quicker ), etc.

    I don’t know of ANY reason to go with spinning-platters, nowadays.

    ( & I’m saying that as a guy stupid-enough to have not realized this in time, & who spent money on such a thing, when SSD’s really were the answer )


  • I would suggest, instead, that “Classical Physics” is created by entanglement:

    the non-quantum reality at our scale is just what happens, when everything is entangled, to the point of clogging-up-the-works of quantumness, as it were…

    .: you get things like … as you scale up from quantum-level … the everything-is-discontinuous/everything-is-turbulence … turns into, once enough entanglement is happening, “laminar flow” in fluid-dynamics, even-though NOTHING in QM is laminar-flow, so there’s simply no basis for “laminar flow” at the lower-level…

    I wonder how significant this is, really…
