  • 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.

    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 )


  • My experience is that USB storage sometimes breaks-connection for no discernable reason.

    That if one REALLY wants to do USB storage, then put it inside the housing, and don’t use one of the external-connectors, use something you can permanently-fix, so nothing can even sneeze in its direction.

    This mayn’t help you with your puzzle, but it’s bedrock and unchangeable, in my experience.

    USB-storage is an unreliable joke.

    ANY revision of it, that I’ve tried.

    hth…


  • No: once a corporate-culture gets sufficiently divorced-from-reality, then they “have their heads up their asses” sooo far, that they commit blunders unless they “get a reality-check”.

    Committee-culture’s fungus-minded.

    The problem is that the frame-of-reference is relative, so a corporate-culture which is still immersed in outer-customers’ reality is only one “degree” divorced-from-reality.

    However, if the “frame-of-reference” of a culture is other sociopathic cultures, … then … then outright psychopathy becomes recommended/pushed/evolved, in order to compete among the misperceived-context ( which is only other-sociopathies ).

    So, it’s an escalating positive-feedback-loop.

    Sociopathy breeds sociopathy, & when enough of the corporate-frame-of-reference is sociopathy, then psychopathy becomes primary, & eventually it is normal & ruling.

    The increasing polarization in political-sphere, in religion/fundamentalism-sphere, in moneyarchy-sphere, in legalism’s increasingly shameless contempt-for & eradication-of moral/natural law, the increasing polarization of class-system/monarchy among those in-love with that, the bolder & bolder violent authoritarianism…

    it’s all part of the SAME gorgon/hydra, just that each “serpent” is going in its own direction, but the fundamental change in human-unconscious is one of “fuck considered-reasoning: I’m going with ideology-enforcing!!”…

    it’s less intellectually-taxing to be ideological/prejudiced “believer” than it is to remain loyal to considered-reasoning…

    there’s less moral-anxiety within ideology/prejudice/belief than there is in considered-reasoning…

    Overwork unplugs one from the push/pull cycle, the work-hard/rest-deeply cycle, which considered-reasoning requires…

    & Microsoft is only 1 single example of progressing-through-sociopathy-into-psychopathy among our countless corporate world-possessors.

    DarkHexad dimensions of human-evil:

    Narcissism / Machiavellianism / Sociopathy-Psychopathy / Nihilism / Sadism / Systemic-Dishonesty.

    Can you see how the more one immerses oneself in DarkHexad as a means of “winning”, the more one’s frame-of-reference normalizes that all?

    It’s just “drift”, but in frame-of-reference, is all…

  • The problem isn’t “making the majority of it noise”,

    the problem is tossing-out the actual-noise, & compressing only the signal.

    Without knowing what the actual-signal is, & just trying to send all-the-noise-and-signal, they’re creating their problem, requiring 200x compression, through wrongly-framing the question.

    What they need to actually do, is to get a chip in before transmitting, which does the simplification/filtering.

    That is the right problem.

    That requires some immense understanding of the signal+noise that they’re trying to work on, though, and it may require much more processing-power than they’re committed to permitting on that side of the link.

    shrug

    Universe can’t care about one’s feelings: making-believing that reality is other than it actually-is may, with politial-stampeding, dent reality some, temporarily, but correction is implacable.

    In this case, there’s nothing they can do to escape the facts.

    EITHER they eradicate enough of the noise before transmission,

    XOR they transmit the noise, & hit an impossible compression problem.

    Tough cookies.

  • IF you want to create accountability among such arrogent tech executives,

    THEN you need to enforce accountability, and 1 excellent way of doing it, would be to immediately, & permanently, ban the CEO of that company from having any right to any in-country right to purchase anything.

    Force THEM to be subject to the abuse they enforce on “their inferiors”, and … oh, suddenly their motivations appear from “nowhere”??


    Enforced-accountability against executives & oligarchs needs to be automatic, not “politically impossible, because they’re the privileged ones, with real rights”, the way our current dogshit for-profit manufactured “culture” insists.

    USB-storage isn’t reliable.

    Period.

    ANY fscking thing that bumps any connection, can break the dam link.

    Then your kernel can re-label the device when it re-connects,

    and you’ve got to reassemble your RAID.

    just my experience.

    use ANY other method you can, other than USB.

    stick a SATA adaptor on there somewhere, if you can.

    Get a different motherboard.

    ANYthing, but not USB.


  • I read that Scarlett’s family & friends couldn’t tell it apart from her actual voice.

    I’d say that “Open AI” or whatever they’re called, trained it specifically on only her voice.

    The seems-narcissistic-machiavellian-sociopath-CEO whats-his-face tried to get her to agree to this,

    she wouldn’t agree,

    he tweeted “her” when releasing the update ( after Scarlett’s movie )

    she lawyered up,

    he backed down…


    I’d say it’s a clear case of identity-theft-for-profit of a celebrity, by a consistently narcissistic-machiavellian-sociopath who’s kinda leaving lots of corpses of “integrity” all over the place.

    There’s some law which protects celebrities from use of their likeness, and rightly:

    it’s their “coin” that their career is made-of, right?

  • When a handful of monopolies decide that no factchecking will be seen by anybody, anymore,

    and only profitable-to-their-dictatorship disinformation will be seen,

    then humanity will not have any means of countering that:

    it will be too late.


    We are “the frog dropped into the slowly-heating pot of water”.


    People pretend that monopoly is “maybe” harmful, economically, but it is an existential-threat to countries, and with globalization, now to civil-rights as a valid-category.

    Reliability’s kinda high on my priority-list.

    Try Samsung.

    Nowadays I can’t imagine using SATA for anything but archival storage ( get the fastest NVMe you can for your operating-system, and be stunned by how much quicker your machine is ).

    Last time I was digging into stats, the reliability-rate for Samsung devices was much higher than that of Western Digital,

    and the off-brands … often are a bit of a bad-joke, for reliability ( Adata & Kingston, I’m looking at you, and will never trust such scum again ).


    just my experience/opinion, is all.


  • SanDisk usb-keys work.

    You really want to use the thing for read-only, though, if you can:

    the writes it takes to kill some portion of a filesystem, vs the writes you get before corrupting things, on a USB driver, don’t line-up.

    Use NVMe as your 1st-choice for storage ( future purchases, obviously ), the fastest you can get, and be stunned by how much faster the same motherboard is, with superfast OS storage…


    I’d stick /home, not /usr, on the USB.


  • IF JBOD, && Linux, THEN yes you can know, through SMARTTOOLS, or something like that…

    However, I can’t imagine how you’d get 2 separate PCIe

    ( presuming NVMe devices …

    … no, this thing must be presuming SATA, NOT NVMe …

    even in SATA, there’s no bifurcator for SATA, I don’t think:

    SAS has expanders, which can take a single SAS channel & attach something like 128 SAS devices onto it,

    PCIe has some kind of equivalent, and there is a PCIe card which crams loads of NVMe’s into it, out in the last year, but SATA??

    Hmm… )
