Reply to comment by reclusive_ent in San Francisco police propose using robots capable of ‘deadly force’ by Majnum
I suggested this idea on the police sub and they absolutely hated it. For suspects that are possibly giving up, have a mechanical hand cuff and have them cuff themselves before the officers come out of cover (cameras, latch that detects it's closed correctly, maybe attached to a heavy ass robot.)
For non-compliant suspects, pepper spray or taser deployed from the robot.
They said the suspects would use the robot as a weapon and many suspects would try to break it just out of spite.
But if it means both the officer and the suspect survive I feel like it's worth it.

Reply to Extreme heat will change us by SigmundFreud
Add increased humidity in some areas and the temperatures become literally unsurvivable beyond a relatively short period of time (hours).
The human body cools mainly via evaporation. Too hot and too humid and you have a wet bulb event (wet bulb is a simple way of measuring heat + humidity) where the body cannot physically cool itself faster than it generates heat. The body's core temperature rises continuously until multiple organs begin to fail and the person dies, unless they can find some kind of cooling.
(The scariest heat related organ failure is that so many of your muscle cells die, the kidney cannot filter out the excessive protein in your blood. And of course the kidney would likely be damaged directly by the heat, so it's a one two punch.)

You are right. He stops after he exceeds the other player's score.
Eric's world record by himself (not head to head) is much higher than the score he posted on the clip, so he could have theoretically kept going.
I read the official rules and the judges can let him keep going if he wants to run up a high score. I think he stopped to save energy because the head to head matches are best of five and he had more matches afterwards?

I think it's called rolling.
Basically, they are holding their fingers and the gamepad surface still and rolling the entire back of the controller around the gamepad surface.
This allows them to move the controllers super fast.
Since NES gamepad buttons and surfaces are pretty small, they are pretty hard to manipulate really quickly. By flipping the controls and moving the back of the controller and keeping the gamepad surface still, they can make bigger movements, faster.
I think you need the insane speed to get near max input speed (I believe max speed that the game enforces is 12 inputs a second but my memory might be wrong.)
Edit: https://youtu.be/n-BZ5-Q48lE that's an explanation of the physical play techniques the best players use to get world records in Nes Tetris.

I think the goal is to score as high as possible in a set amount of time or lines.
The game was over when he raises his hands. You can see the screen going white.

Good on them. It doesn't matter what theoretical guidance the CDC is putting out or whatever the textbooks are saying. If something is observable clinically, either the text books are wrong are there's some other phenomena that's not being accounted for. Either way, take action against what you're observing.

The terminology is unclear, which doesn't help.
Let's just call everything a droplet and say that droplets over 100 microns tend to fall out of the air quickly and droplets under 100 microns can remain in the air for a longer time (depends on humidity and other factors, but that's the general rule.)
"Aersol", "airborne" and other terms differ in meaning depending on which specialilzed domain you are talking in.

The original aerosol research was performed in the 1930s and the 100 micron number was correctly cited for a bit.
Years later, some research into TB discovered only the smallest particles, 5 microns and smaller, could get deep into the lungs and cause TB.
A paper mistakenly used the 5 micron number as the max size of droplets that remain in the air and other papers in public health repeated the mistake.
What's interesting is that the mistake only propagated among public health researchers. Aerosol physicists were using the right number all along and it was only when aerosol physicists started looking at SARS-CoV-2 that they noticed public health was using the wrong number.
Turns out, public health was never in the habit of talking to aerosol physicists and aersol physicists were mainly focused on pollution. It was just a weird case of siloing that the experts didn't talk to each other until a pandemic forced them to.

A study estimates that touching a contaminated surface would lead to infection with SARS-CoV-2 only 1 in 10,000 touches.
https://www.cdc.gov/coronavirus/2019-ncov/more/science-and-research/surface-transmission.html
Then you have to take into account how long a surface remains contaminated or what it takes to contaiminate a surface.
Overall the risk is considered low and the main transmission pathway is considered respiratory droplets.
There's a "funny" story about why public health initially assumed SARS-CoV-2 was not spread via respiratory droplets: they accidentally used the number 5 microns as being the max size of water droplets that behaves airborne. The real number is closer to 100 microns. Once public health realized they were drastically overestimating which droplets will fall out of the air rapidly, they realized that the airborne respiratory droplets made a lot more sense and jibed better with what the case studies and experiments were showing about SARS-CoV-2 transmission. This same mistake plagued flu research as well and it explains why fomites were a mistaken emphasis around both flu and Covid prevention.

Reply to comment by -Daetrax- in TIL that after the battle between the USS Constitution and HMS Guerriere, the captain of the Constitution, Isaac Hull, refused the sword of surrender from the captain of the Guerriere, James Richard Dacre, saying he could not accept it from a man who fought so gallantly by alcapwnage0007
That only happened on the TV show. In interviews he says he kept that pistol as a prized possession.
