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.

for sure, its perfectly reasonable to say “this tool isn’t useful for me”

its another thing to say “this tool isn’t useful for anyone”

nice.

can usually get a pretty good performance increase with hand writing asm where appropriate.

don’t know if its a coincidence, but i’ve never seen someone who’s good at writing assembly say that its never useful.

gonna use this as an opportunity to launch my ted talk:

there’s no such thing as anything but “race mixing” since every single human on the planet is a mix of different ancient races anyway

(or to put another way, race is a bs term anyway since we’re all homosapiens)

why does it need to be device agnostic?

happy to get into into these subtopics, but it’s also possible i may not be understanding you properly because i agree with alot of what you just said.

what are you attributing the close to 0 probability to?

if you wanna say “whats the probability that CMG was at least partly talking out their arse about their capabilities (and especially any claim they were currently in possession of that capability)?”

i’d also give it like >90% probability they (CMG) are full of shit. in which case you could say i agree with you (to within say 10% error margin).

if you’re instead saying the probability is ~100% that audio surveillance capability cannot possibly currently exist outside TLAs because “someone would’ve published it already” then i really cannot agree. (and afaict that ars article does not support that stance either)

Not disputing the three letter agencies

The capability they were claiming to have would make a three letter agency very excited.

sorry i didn’t understand. didn’t you say you don’t doubt TLAs likely already have this capability?

oppressive regimes

most (all?) of whom are operating outside typical legal constraints and likely already have access to the million dollar exploit trade which already exists.

further, i’m not sure how this changes the landscape anyway? its not without precedent that variations on capabilities can be useful to more than one market segment concurrently?

trivial to discover and flag as malware

can you explain further what you mean by this? i’m not sure there’s anything trivial about conclusive analysis of the deep complexities and dependencies of modern smart devices

Apple and Google would also be very keen to find and squash whatever loophole let’s them record without showing the notification.

historically we’ve seen google can take over half a decade to address such things, afaict (welcome correction on this) apple’s generally been faster to respond, and i do agree apple’s current public image attire would be contrary to be seen to enable this. [not simping for apple btw, just stating that part of their brand currently seems to be invested in this]

in reality there are a confluence of many agendas and there’s likely ALOT of global users running non-bleeding edge or other variations on the myriad of sub-system components, regardless of what upstream entities like google implement. if you are aware of any conclusive downstream binary analyses please link

which if true would have been exposed/validated by security researchers long ago.

i agree the probability of discovery increases over time. and the landscape is growing more hostile to such activities. yet i’m not aware that a current lack of published discovery is actual proof it’s never happened.

tbh we have our doubts this leak is directly connected to solid proof “they are listening”.

but we’re not currently aware of any substantiated reasons to say with certainty “they’re absolutely not listening”

well they’re an ad company, so being full of shit is pretty much mandatory.

but i’m not aware of any evidence they’re actually 100% full of shit on this exact issue or not? can you explain a little more how you know for certain they’re full of shit. or you just meant “they’re most likely full of shit”?

honestly i think this is due to unplanned voice calls essentially being broken technology now.

imagine we had 2020s email spammers while mail servers had 1990s spam filters, that’s basically where we’re at now with unplanned voice.

Yeah I don’t know. Just see how the modern world is shaping society to the negative I just don’t see where we are close to utopia But right now we are on a different path

That was essentially a big part of my point. We could be close to a utopia by now (from the perspective of technological possibilities).

Instead, as I said

for some suspicious reason we took a very different road, and here we are

That said I don’t currently believe technology itself is inherently bad.

Like all tools, it depends what you do with it.

Is a general purpose tool like hammer good or bad? It has the capacity for both. And therefore it’s up to the user which is which.

And that’s the issue really, what are we doing with our wonderous technology?

This might be a bit of a radical take. But in that ~125 year window i was refering to, alot of machines we’ve invented are actually weapons.

Weapons to destroy eachother physically (conflict/threats of violence etc).

Weapons to destroy nature (deforestation and probably most mining).

Weapons to destroy the mind (social media etc, actually most media now).

What if we’d had 1+¼ century of building a collective utopia instead of all these weapons?

afaict from the technical perspective it’s not really unfeasible, its the non-technical problem: the user and what they use the tools for.

Another clue for us is probably the term appropriate technology, which is a vibe i think eg. solar punk is helping to cultivate.

Anyway we’ve done ALOT of misuse. That’s why i don’t blame technology itself.

I still think it’s more about what we’ve done with it.

necessary decline in our quality of life

i’m not refuting your core premise.

but on the note of this issue, not sure i can agree.

have a look at this public infrastructure technology from 122 years ago:

Youtube/Invidious

imagine if we’d spent the last 1+¼ century collectively working towards the utopia this kind of project hinted at - instead of developing new machines to destroy?

typically they say utopian dreams scatter in the face of increased technological awareness. have to say my experience has been the opposite.

the more i learn about technology, the more i realise we could probably be very close to a near-utopia by now. for some suspicious reason we took a very different road, and here we are.

i reckon there’s a good chance she was trolling. and if so, fuckin well played.

you make excellent points, but not sure i can agree with your conclusion

if we had full source a variety of automated analysis and hardening tooling could be applied which is much much more efficient compared to parsing the arch docs.
