  • TLDR edit: I’m supporting the above comment - ie. i do not support apple’s actions in this case.


    It’s definitely good for people to learn a bit about homomorphic computing, and let’s give some credit to apple for investing in this area of technology.

    That said:

    1. Encryption in the majority of cases doesn’t actually buy absolute privacy or security, it buys time - see NIST’s criteria of ≥30 years for AES. It will almost certainly be crackable <oneday> either by weakening or other advances… How many people are truly able to give genuine informed consent in that context?

    2. Encrypting something doesn’t always work out as planned, see example:

    “DON’T WORRY BRO, ITS TOTALLY SAFE, IT’S ENCRYPTED!!”

    Source

    Yes Apple is surely capable enough to avoid simple, documented, mistakes such as above, but it’s also quite likely some mistake will be made. And we note, apple are also extremely likely capable of engineering leaks and concealing it or making it appear accidental (or even if truly accidental, leveraging it later on).

    Whether they’d take the risk, whether their (un)official internal policy would support or reject that is ofc for the realm of speculation.

    That they’d have the technical capability to do so isn’t at all unlikely. Same goes for a capable entity with access to apple infrastructure.

    1. The fact they’ve chosen to act questionably regarding user’s ability to meaningfully consent, or even consent at all(!), suggests there may be some issues with assuming good faith on their part.



  • that’s great buddy. but while recapping basic IT facts might make you feel smart on facebook. this is lemmy where the average user 1 is perfectly familiar the principles. here it just telegraphs to us that you didn’t read the fucking article (which would’ve taken less time than spamming the thread & insulting users btw).

    1 before the influx of reddit api refugees - on that topic do you ever reflect on how corporate bootlicking might relate to the over-corporatisation of reddit which led to users fleeing? only to come here and do unpaid simping for the corporations, slowly ruining this place too?









  • yes, as i said

    from the article it’s not clear what the performance boost is relative to intrinsics

    (they don’t make that comparison in the article)

    so its not clear exactly how handwritten asm compares to intrinsics in this specific comparison. we can’t assume their handwritten AVX-512 asm and instrinics AVX-512 will perform identically here, it may be better, or worse.

    also worth noting they’re discussing benchmarking of a specific function, so overall performance on executing a given set of commands may be quite different depending what can and can’t be unrolled and in which order for different dependencies.


  • from the article it’s not clear what the performance boost is relative to intrinsics (its extremely unlikely to be anything close to 94x lol), its not even clear from the article if the avx2 implementation they benchmarked against was instrinsics or handwritten either. in some cases avx2 seems to slightly outperform avx-512 in their implementation

    there’s also so many different ways to break a problem down that i’m not sure this is an ideal showcase, at least without more information.

    to be fair to the presenters they may not be the ones making the specific flavour of hype that the article writers are.




  • hey man, i think you may have misinterpreted who i was replying to /what i was saying, or perhaps i didn’t communicate perfectly.

    i am 10,000% on your side with this, and very much appreciate your post and appreciate your support in this thread/community on this topic. it’s actually giving me a tiny bit of hope that this community isn’t entirely lost.

    i’ve really grown absolutely weary of the ridiculous denialism in society and especially in so-called tech communities on this topic.

    the kindest thing i think you could say about the rampant denialism is they emotionally do not want to believe it could be happening, and therefore all rationality has gone out the window.

    these threads are always a circle jerk of denialists repeating popular media headlines which say “its not happening”, and then if you read the article IT DOESN’T SAY THAT AT ALL. and these denialists WON’T EVEN FUCKING READ THE ARTICLES THEY POST.

    apart from the emotional cope, perhaps also partial exposure to eg. basic consumer stuff like installing steam or downloading a movie, so they assume the bandwidth is too high to exfiltrate audio cos their music/game/movie audio files are big, completely ignoring the fact that the telecomms industry has put many decades and $ into producing efficient voice codecs for around 50 years now. they probably think nyquist is a brand of cough medicine

    same goes for all the other erroneous ‘consumer tech’ false facts they parrot back and forth.

    eg. the lunacy of saying the tired old statement “if they were listening ALL THE TIME, we’d know” completely ignoring threshold based noise gates have been a thing for well over half a century.

    these self-proclaimed know-it-alls can’t even put in 10 minutes reading BASIC topics in an encylopedia to realise this shit was solved over half a century ago. (actually you don’t even need tech knowledge or an encylopedia to imagine such a fundamental thing as…i don’t know…not recording when nothings happening 🤯). they can’t put in even BASIC effort, yet are SOOO smug in not only telling us “its absolutely not happening”, but they actually can’t wait to be rude and ridicule randoms for even asking the question.
