It probably wont... till someone fires the one in 10 actually useful one and remaining ones will just fold down

That makes it a bit harder, most people don't have access to accurate power measurement device.

Kinda shame USB hosts don't have that functionality

> Interruptions don't scale, just as single backbone networks don't scale (CSMA-CD anyone?) and modern networking has shifted to star topologies.

The difference is that packet has max length and therefore can be mixed with other senders, not be infinite monologue that chokes whole traffic in the network

As for interrupts, you just need to queue them instead of them causing collision. Notice the need for question and let the other side finish the sentence, as what they say next might be answer to question

Yup, and that is how ultrasonic heat pumps work!

JWST has one

https://webb.nasa.gov/content/about/innovations/cryocooler.h...

basically, make a standing wave of gas in a pipe and the peak of pressure will be hotter than the valley. Put the thing you want to cool in the valley, radiator in the peak, and voila, a heat pump.

To elaborate, the tube is tuned right below where in closed box the speaker would lose efficiency, so the frequency shift is 180 degrees, and as it takes air from behind it (which is shifted by 180 so it gets to 360 total). But that causes the frequency curve to drop steeper below that.

There is also variant of that where instead of pipe hole there is an extra passive membrane

> Interesting side note - using the "basic" frequency/amplitude slider section, you can tell if you have any hearing loss in a certain ear at a certain frequency, as well as high frequencies in general.

If you're on headphones maybe but might "only" be shit speakers

Pretty much, I'm scrolling for few minutes and every demo is more impressive than the previous one.

And the part about sound bouncing in the room is basically "acoustic room design 101" and beautifully illustrates how shape and dampening of the room can massively change how it sounds
