Lie down, do a push up, then jump up to your feet, upright, arms raised (Burpee). Repeat in rapid succession twelve times, then immediately shut your mouth and close your nose with your hand. Hold it. Close your eyes and imagine you are under water and don‘t know how long it will take till you can resurface.
You will feel an immediate urge to breath, a very unpleasant feeling in your throat, nose, ears, etc, and an immediate feeling of panic. That feeling is AFAIK caused by heightened CO2 levels [1].
Imagine trying to fight your way to the surface, in a panic, but the turbulence of the wave is too strong and keeps you down. Instead you have to accept the feeling of panic without acting on it, converse your energy while being rag dolled and pounded, trying not to dislocate your joints, keep or regain your sense of orientation, and wait for the moment that the turbulence subsides to the point it is possible to surface again.
You have little control over when that moment finally comes. And while seconds start to feel like eternities you might start telling yourself to never go surfing again. As time drags on, your resolve increases, to the point you might act on it once, and if, you finally resurface.

you forget, ‘put a blindfold on and tie your leg to a doberman’s leash then fall down 3-6 flights of stairs’
pretty similar forces and sensory at play, or at least a similar thrashing to big Teahupo’o over a sharp reef.
A safe way to get a similar disorienting experience is hold your breath under water while in a tight ball and have someone spin you on every direction and reverse it until you can't stand it and then wait another ten seconds.
I recall being swallowed by a wave and while under for only a short period i thought it was annoying not knowing when I'd return to the surface.
I've only taken the SSI training but I guarantee none of the different freediving organizations will recommend the type of breathing you are discussing, and in fact a large part of the intro course hammers home that you don't breathe that way.
Any freediving course. You have to breathe normally for an extended time, then dive, then take an extended break, hyperventilation just makes it easier for you to get yourself killed.
The people around the pool and lake where I grew up? From what I'm reading while searching it seems that "hyperventilate" is probably a bad term for the type of breathing I was shown. We wouldn't do it until we felt a conscious change like dizziness but more like 4 to 8 good deep full and fast breaths before holding, enough to notice, but not so much that it presented the dangers I'm now reading about.
That is still considered hyperventilation as a freediver, even though you might not feel any symptoms. The suggestions you gave in your previous post are dangerous and should not be done. Please take a proper course to learn about free diving physiology and safety. Otherwise this sport can get dangerous very quickly.
Interesting analysis but not sure it‘s correct. The subscribers are likely consuming much more resources than the free users. A 20$/m user might consume much more than that in compute, thus creating a loss.
Wrong. The first Tesla, the Roadster, was an existing design by Lotus [1]. All Tesla designs since, including the Cybertruck, have been led by Franz von Holzhausen.
> But how would an automatic rice cooker know when the 20 minutes was up?
How about a clock?
Now, I understand that in 1955 the required components might have been deemed too expensive, or actually the problem is more complex than that. This article is so poorly written. Like almost everything I've read in the last 20 years from IEEE Spectrum.
Well, I would have thought that once a temperature sensor reads 100 deg Celsius the clock would start. I'm sure there are good reasons why this wouldn't work well or is overly complex, but I would expect the article to discuss them.
From the article:
> Fumiko found that heating the water and rice to a boil and then cooking for exactly 20 minutes produced consistently good results.
That knowledge about the ideal timespan of 20 min seems to be completely irrelevant to the implemented solution.
> That knowledge about the ideal timespan of 20 min seems to be completely irrelevant to the implemented solution.
Partially. They also mentioned that it was generally believed that you needed to vary the temperature during cooking to get fluffy rice. Fumiko's discovery is just as much about the fact that you can use a straight boil the whole time as it is about the duration.
I had the same question, and this article definitely could have discussed other potential engineering approaches and why they didn't work to provide the full context. To be honest, I learned very little from the article -- I already know how rice cookers work, so I want to learn much more when I decided to read the article
Starliner is a reusable spacecraft. Since it lands in the desert, it should be easier to refurbish than Dragon, which lands in the sea.
But all that is mostly theoretical unless Starliner becomes a reliable spacecraft.
It sure makes sense.
The endorsement is extremely unlikely to decide the election.
On the contrary, the chance that the endorsement will lead to retribution after a lost election is arguably much higher. They think it happened last time around.
You can say it's cowardly to act like this. But it does make sense.
> say it's cowardly to act like this. But it does make sense.
So cowardice has been the greater virtue all along?
Has it come to this, that political cowardice makes sense? That it makes sense when Democracy itself is at risk?
That it makes sense in Journalism?
That it makes sense at the newspaper of Bob Woodward [1] , now run by a billionaire with no guts to stand for Democracy itself?
That other oligarchs are tilting the election towards the obvious insanity of a leader who, in word and deed, will dismantle Democracy to indulge himself and his cronies?
We have sanewashed madness and the end of Democracy.
