    did anyone read the link?

    tldr: i’m not the one making these ridiculous claims, it was a statement made (apparently in earnest) by a loopy politician.

    “You would be giving off more CO2 if you are riding a bike than driving in a car,” he said. However, he said he had not “done any analysis” of the difference in CO2 from a person on a bike compared to the engine of a car" 😂






  • seems like i’m mostly telling people in this thread not to feel bad about their prior cringe…

    i really didn’t follow this closely AT ALL. but i feel like back in the day libertarian ideas were much more left of center than they are now. to my inexpert perception, it feels like libertarianism (and alot of other things) have been co-opted by conservatism over the years.


  • which version of the hollow earth are we talking? if you mean a giant hollow shell, then yeh i’m not sure how well supported that is.

    if you mean the honeycomb earth idea, where there could be myriad of huge deep caverns. then i’m kinda open to that possibility.

    (not that my geoscience knowledge extends beyond highschool geography and the odd wikipedia article - so would welcome an opportunity to discuss with someone adept.)


  • 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.





  • yeah the level of technical competence on this site has plummeted since the influx of the reddit crowd.

    just enough consumer tech enthusiast knowledge to delude themselves they can smugly and self righteously shit on the average non-tech person.

    and now they’re the majority, drowning out legitimate curiosity by loudly parroting headlines from articles they didn’t even read. slowly turning lemmy into the regurgitated reddit pop media shithole they wanted to escape.

    this topic is especially difficult because of the clear emotional desire for it not to be true. hence the degree of fragile cope in this thread.

    thankfully not everyone here is a lost cause, and you’ve been given some good advice on delineating the other possible causes for what you’ve observed. when we do a careful analysis we must ofc consider all possibilities.

    what i’ve not seen properly acknowledged in this thread, however, is that the possibility of alternative explanations doesn’t preclude the possibility of voice-based surveillance either.




  • Of course a researcher is never sure something is 100% ruled out. That’s part of how academic research works.

    once again, that isn’t what they were reported to have said. [and researchers don’t need to repeat the basic precepts of the scientific method in every paper they write, so perhaps its worthwhile to note what they were reported to say about that, rather than write it off as a generic ‘noone can be 100% certain of anything’] it’s a bit rich to blame someone for lacking rigor while repeatedly misrepresenting what your own article even says.

    what the article actually said is

    because there are some scenarios not covered by their study

    and even within the subset of scenarios they did study, the article notes various caveats of the study:

    Their phones were being operated by an automated program, not by actual humans, so they might not have triggered apps the same way a flesh-and-blood user would. And the phones were in a controlled environment, not wandering the world in a way that might trigger them: For the first few months of the study the phones were near students in a lab at Northeastern University and thus surrounded by ambient conversation, but the phones made so much noise, as apps were constantly being played with on them, that they were eventually moved into a closet

    there’s so much more research to be done on this topic, we’re FAR FAR from proving it conclusively (to the standards of modern science, not some mythical scientifically impossible certainty).

    presenting to the public that is a proven science, when the state of research afaict has made no such claim is muddying the waters.

    if you’re as absolutely correct as you claim, why misrepresent whats stated in the sources you cite?


  • no, they don’t

    Please be careful with your claims.

    In my experience, whenever investigating these claims and refutations we usually find when digging past the pop media headlines into the actual academic claims, that noone has proven it’s not happening. If you know of a conclusive study, please link.

    Regarding the article you have linked we don’t even need to dig past the article to the actual academic claims.

    The very article you linked states quite clearly:

    The researchers weren’t comfortable saying for sure that your phone isn’t secretly listening to you in part because there are some scenarios not covered by their study.

    (Genuine question, not trying to be snarky) Will you take a moment to reflect on which factors may have contributed to your eagerness to misrepresent the conclusions of the studies cited in your article?


  • Anyone saying they know for 100% certain it’s not happening is probably speaking from their emotional desire for it not to be true - rather than actual fact.

    Anyone who has looked into the actual technical aspects, rather than spouting the usual surface-level “tech facts” or parroting headlines (rather than the actual academic findings), cannot seriously claim to know for certain its 100% not happening.

    @op i would advise caution on stating ‘24x7’ until there is evidence of that specific claim. (unless you’re referring to while voice assistants are enabled.)


  • its BIG. could be great to see some different teams tackle different issues.

    for example a transcode team to tag and convert different media to the latest efficient formats might save alot of space.

    and eg. voice-only recordings could be suitably encoded vs music etc

    also some methods for diffing snapshots, or some kind of compromise on snapshots storage with minimal changes? not ideal but might be enough to get across the line maybe?

    re. the “most important”, aside from specific items or archives, imo a crucial role might be text-only snapshots of most of the web. would help increase accountability amongst modern media outlets, journalists etc
