why not just detach the warhead and save the drone?

What I've read says that this is a modular system, likely some variants will launch small air to air missles, and others use large shotgun shells to take out drones.
Nomentatus commented on USB inventor explains why the connector was not designed to be reversible (2019)   pcgamer.com/usb-inventor-... · Posted by u/thunderbong

The plug didn't have to be reversible - it could just have had a trapezoidal cross-section. No significant cost.

Terrific. Maybe not the most alluring framing.

Could be titled "Hate Elon? OMFG would you have hated Edison! He was way worse!"

Scientists didn't start getting in the way of progress yesterday. It's a tradition:

When the dynamo prototype was finished, it operated so contrary to existing best-practice that Edison was mocked for it. John Tyndall — the physicist to whom discovery of the greenhouse effect is often attributed – wrote in the Journal of Gas Lighting, ‘It is difficult to adequately express the ludicrous inefficiency of the arrangement; but one thing is abundantly certain, and that is that the person who seriously proposed it was wholly destitute of a scientific knowledge of either electricity or the science of energy.’

Nomentatus commented on Searle's Chinese Room Argument   en.wikipedia.org/wiki/Chi... · Posted by u/Eddy_Viscosity2
Nomentatus · 3 years ago
The closest real world example of the Chinese Room I know about is Richard Feynman's adventures teaching physics in Brazil. His students memorized the textbooks and could manipulate the symbols, and answer test questions correctly,"because they were "almost exclusive teaching and learning by means of pure abject memory." They also never tested their knowledge against that of their friends in discussions, for fear of losing face.

Therefore, when it came to any experiment or application in the real world, the students were as hopeless as if they knew nothing. They had just been playing a symbol-swapping game.

That might be possible with good blackout curtains, except for the LEDs on damn near everything. Even in my own room at home, I have to remember to cover the USB charger that I use for laptop and random other devices. When I travel, it's a nightmare - clock radios, TVs, microwaves, and especially the lights built in to many GFCI outlets in bathrooms. I used to bring a roll of electrical tape for exactly this reason. Masks are the solution that works everywhere to block light, though they're less than ideal in other ways.

Someone needs to sue any manufacturer that uses blue leds on anything that might have to be on at night.

I bet that with your eyes closed, the difference between "black out blind dark" and "no light" isn't much. I bought black out blind about 5 years ago and they're amazing. If I'm in my parents house or staying in a hotel during summer, I get crappy sleep and I'm wide awake at 5am.

I might mention that, believe it or don't - a living skull is translucent, and our brains can detect light all by themselves. So a mask is good, but not nec a whole solution.

In old experiments, just the light coming in under a door diminished melatonin in mice.

If it's just the amount of light as per abstract,I assume darkened room would be equivalent I.e. There's no magic additional benefit of mask itself (pressure / touch / etc)?
Nomentatus · 3 years ago
Right. But a dark room is a room in which, if you put your hand in front of your face, you don't see even the faintest outline of a hand.

How poignant, that the obvious solution is the worst "solution" of all, due to human nature.
