I'm sure systems vendors will love putting these in Windows laptops (a growing market with a bright future, I'm sure) but I can't imagine hackers having much use for these things.
> Another cool use of low power, always-on DSPs is using ultrasound sonar to detect humans. AMD’s ultrasound runs at above 20 KHz but below 35 KHz, letting it get through the microphone and speaker’s band pass filters. Then, it can use Doppler shift to distinguish human movement from static objects in the same way that a look-down radar filters out ground clutter.
This chip sounds pretty creepy, although I doubt it'll be possible to escape from this sort of thing. The US spies will be loving these feature trends.
All laptops with a 5 kHz tone would be returned as defective. In the 90's harddrives often had a 7200 Hz whine which was enourmously annoying. Todays harddrives are silent compared to the old ones.
I'm unlucky enough to hear 15 kHz, and you'd easily hear any TVs turned on two storeys away. CRT ultrasounds used to be unbearably, migraine-inducing loud.
I assume laptop speakers wouldn't be anywhere as bad.
The what now ? nothing in hard drive runs at that frequency
But whether anything is bothered by the sound depends on the energy level and other characteristics. Spread spectrum ultrasound sonar below the local noise floor may be technically feasible, though perhaps not with regular laptop speakers and audio circuitry.
Occam’s razor would suggest it’s because accurate documentation would create worse PR.
That’s not reassuring at all.
It's extremely likely it is.
The only Linux based OSes that are on pair with it are ChromeOS and Android.
A random Linux distribution can be a very minimal one, and can have sandboxing too, which is what I presume what you equate to security.
Linux sandboxing isn't on the same level as Windows 11 Professional, as it doesn't do user space drivers for most stuff, runs drivers in their own sandbox and has critical kernel components running on their own sandbox.
All coupled with hardware attestation zones via TPM, SGX and now Pluton.
Nothing except the last part you said about Windows 11 is true. And the only "critical kernel component" which as of today by default runs on its own sandbox is the protected media path, aka DRM. Anything that could even be remotely interesting is not available on the Pro edition.
Considering Microsoft's general security posture (e.g. check the number of critical cross-tenant and trivial to exploit security issues in Azure - which is unique among cloud providers in their number, criticality and triviality), I wouldn't trust them in the slightest. I know Azure and Windows are different business units, but if nobody in Azure cares about reliability or security, as is obviously the case, I severely doubt that's an organisation that puts emphasis on either.
Win32 apps are now sandboxed.

I know because suddenly I wake up and see that Sumatra PDF Reader is now operating in sandbox mode.
However Linux is not to blame that it's used in idiotic IoT and server configurations.
This sort of citation or "research" is not remotely what the CVE database is for.
I am not playing the citation game, already have enough of it during Usenet and not feeling bored enough today.
The availability of Windows source for partners is nothing compared to how many educated eyes are on the Linux source at a given moment.
Of course none of this matters because the BSDs are more secure than both but they wouldn't pick them over Windows IRL anyways. Why Windows are preferred is a matter of business and not technology. This is a long topic and if you were in Usenet advocacies you know what it's all about. Support, logistics, number of trained people in the market, certifications, so on and so forth. Linux doesn't have an easy fight there.
the documented applications of pluton are far more horrifying than the PSP
