I can't speak for Apple, but for my Prusa 3D-printer: Worn/cheap ball bearings will make a rattling sound until they heat up and the balls expand. If you care about the auditory experience, using audio in the feedback loop makes some sense.
The goal is probably not to absolutely manage cooling but to focus on the audio experience and try to keep noise below some threshold.
I think that's an interesting idea, even if not everyone might be happy with the tradeoff (comes down to how much you care about noise vs getting throttled), especially for a vr device.
It is a machine you literally have on your head. I have not tried it, but I can believe that it requires some different UX considerations than normal computers. I would definitely not like to hear fan noise vibrating through my head.
There's a reason why the Vision Pro has separate chip that handles the real-time passthrough from cameras (and bunch of other sensor-fusion stuff, AIUI).
Wouldn't it still thermal throttle as the whole device gets hot, separate chip or not ?
I understand the threshold for heating up should be lower than with integrated chips, but we're talking about fan speeds, about when that threshold is still reached and cooling is needed.
In the old days, the device settings would allow the user to tune the trade-off to their own preferences. But current user design orthodoxy is that "settings are bad" to an extreme (I actually agree with the weaker formulation "too many settings are bad"... for some value of "many")
That really depends on what the effects of the throttling are. Stronger foveation or other rendering quality drops? Probably OK. Frame rate dropping below 75? Not in VR, never...
But they're a trillion dollar company because of their relentless focus on the end-user experience which you happen to dislike, but which most people love.
UX isn't NVIDIA's business model. It is Apple's, and they've found there's shittons of money to be made giving a shit about UX, especially when virtually no one else will.
Because the RPM of a fan is not a 100% reliable indicator of its loudness. Sometimes a lower speed can even be louder than a higher one, because of certain resonances...
Yes, that could work (it would need to be done for each fan individually, because of manufacturing variation). But it's still not guaranteed that the fan will keep working the same way in the future, after some use/deterioration or in untested conditions.
Makes sense. Humans are really bad at perceiving the environmental noise floor. Our brains just tune it out, but it is has a huge impact on your perception of the loudness of fans that you've strapped to your face.
I can certainly see things like this causing a lot of unintended consequences. "It speeds up when I play loud music" is going to confuse many who don't know about this "feature".
Twitter doesn’t show threads to people who are not logged in (e.g. if you don’t have an account). Shaming people for not reading what they can’t see (or even know exists) is unfair. Using archival sites doesn’t work as a bypass like on newspaper sites.
Not to mention people on Firefox, which from what I have read on HN might not even have access to it at all.
Twitter links should probably be downranked on HN until (if/when) they return to being more accessible.
With a paywall you know what you’re missing or not. With Twitter that’s harder to determine, which I’d argue is worse. But I wouldn’t say either of our opinions is objectively correct.
> and HN is mostly fine about those.
It is explicitely fine with paywalls which have workarounds.
