> Oh wait you said simpler... Isn't that always the problem with QM? Plus there's no intuitive simplified model to explain and most analogies are so off the mark they do more harm than good. The only way to understand QM is via

I wonder if there is some underlying insight? LEDs are both photovoltaic generators and light emitters... just not well optimized for converting light into electricity. PV solar panels are LEDs too, just highly optimized for the opposite di

I've explained this before but the players involved don't really care. The bank just wants to make sure they aren't on the hook for a worthless shack. If the appraisal comes back inflated by 10-20% that's fine. The goal

Indeed ISDN was amazing for its time but Ma Bell and her successor ILECs were way too proud of it so in the end it went nowhere and never made them all that much money. If they had gotten out of their own way when the internet came around t

Not sure how we could ever prove something like that but it's certainly an amusing and symmetrical view of the universe: big bangs create two universes, moving in opposite time directions from each other. Each seeing the other's p

I agree with this. I got to experience both sides when I interviewed at FB/Meta. I practiced the leetcode and Cracking the Code Interview stuff of course and one of my interviewers asked something like that. I guess it was insulting an

Oh yeah. These posts are the limit of my knowledge. Real-world power plants, switchgear, and grid management is way way more complex! And if you want to talk about "hard real time requirements".... it doesn't get much harder

Good point... oversupply lightens the load on the generator meaning not as much angular momentum is converted to magnetic flux then to an electric field. Unopposed the torque is able to increase the rotor's speed which directly determi

Take a little hobby DC motor and hook it to a battery. It will spin. Now hook it to a small LED and turn the shaft. The LED will light up. In fact hook both up. The battery will spin the motor and light the LED based on its voltage/cha

Generators must synchronize with the grid. Huge spinning rotor masses that will experience tremendous forces to coerce them into matching an RPM that corresponds to the grid's frequency. Frequency is also impacted by load: the greater

Correct. Foundation's NSFileManager / FileManager will automatically use clone for same-volume copies if the underlying filesystem supports it. This makes all file copies in all apps that use Foundation support cloning even if the

Yup. It was never pronounced "yuhee". Sometimes it was written þe, other times it was written with a small "e" above "þ" like a diacritic. Because cursive "þ" looked similar to cursive "y"

Regulation is what apologists will cite but only the three large IOU (Investor Owned Utilities) have such ridiculous electricity rates. Part of the Bay Area is served by Silicon Valley Power which is half or less of PG&E's rates. O

I say this half-jokingly: If you're going to rip a wing off do it as early in the crash as possible so momentum will carry you past the fuel/fireball. If fire develops when you've almost or completely stopped you are now inv

I wonder... LLMs currently work because they have a huge corpus of data to train against. Data generated by humans. What happens when almost all available data is computer-generated? When no new training datasets are available? Will the mod

You two are arguing across each other. JumpCrisscross is saying ignore the 80/20 rule for the insurance side. If you look at UHC's overall parent company profits - the profits after they've calculated in the profit from the

Update: I'll retract part of this. I'll stand by the part about conservative buzzwords and the dogwhistle of "you hired too many women and blacks". But it appears the FAA did have some kind of "biographical question

A man-made object maybe but I don't think there are any natural objects with the right size+density to do it.

Citation needed. "DEI did it" is just the new conservative buzzword for everything. You should be clear what you mean by saying this is DEI: you (and POTUS) are saying "they hired too many female and/or black air traffic

Anything that comes closer than the ISS (give or take) is going to interact with the atmosphere which is going to change the dynamics considerably. Generally something with the right orbit to pass 20m above the earth's surface is going

The latest generation of satellites use software-driven phase array beam forming antennas, effectively behaving like it has hundreds or thousands of tiny spot beams. That allows it "talk" on the same frequency to different receive

By counting grid points it looks like codes in the form 0[1-9][32-99] are the least common with a few exceptions (like 0990 or 0987). I suspect this is leading zero bias: a leading zero is not meaningful mathematically and we tend to drop i

I wonder how will LLMs learn anything new when no one does original research and just asks the LLM? Will LLMs just feed back on each other, effectively hallucinating false "learning"? Maybe we'll end up as a society of a few

I know, I grew up with this stuff. There's never a true scotsman and the goalposts are always moving. Play semantic games. Or just recast everything as God being unable to make choices and never responsible for anything. None of it mat

Punishing people thousands of generations removed who have no responsibility seems sadistic and cruel. If that's how God operates then why not do slave reparations? Why not do a huge series of land swaps to give land back to descendant

Only illegal because they'd have to be stolen. Unlike the 500/1000/5000/10000 notes the $100,000 notes were never issued to the public. They were a relic of the days of physical currency transfer between banks. Not that
