How are rare earths used in batteries?

The simple explanation is just that lot of ways that numbers can multiply to produce the same product

Like an odd number x times an even number y, x* y produces the same product as x* 2 and y/2

Same for a multiple of 3 c and and a non multiple of 3 d, c * d = c/3 * d*3


This is just looking at it from a different perspective. Both, one 64 bit integer and the product of two 32 bit integers represent a number up to 2^64 with 64 bits. But while all 64 bit integers are unique, there are, as you say, several representation for some numbers as the product of two 32 bit integers and therefore it is impossible to represent all 64 bit integers. Commutativity alone costs you about 50 percent of all numbers in the range as x * y and y * x represent the same 64 bit number but with two different representation as a product of two 32 bit numbers, at least if x and y are different. But this tells you nothing about the numbers that you can not represent, only that they must exist. I was looking at it from this other perspective, which numbers are not representable as a product and why.


That isn’t cruelty. It’s immigration policy that the rest of the world already has


That's not true. If I'm in Japan on a work visa, for example, I don't need to leave the country to apply for permanent residency. And Japan is not a country famously welcoming of immigration.


You’re going to need to strongly source this one, sounds completely made up.


All cars require a workforce to maintain though.


Spirit seemed to enjoy making their customers hate them. everyone who liked Spirit had to explain themselves (like you did) because their reputation was awful. It was a trainwreck of a brand.


The only bad experience I ever had on Spirit was from their garbage passengers, never had a problem with the airline itself, flew them probably 20 times. But then again anecdotal evidence is also garbage, so who knows, maybe we were just lucky. Or maybe a vocal minority made it sound worse than it was.


Or the big airlines were paying for all that disparaging marketing on the down low. I wouldnt be surprised.


I would be surprised to hear that, say, United, was paying people to post about their bad experiences with Spirit Arlines online. I'm not in marketing though so maybe that's a thing that happens.


20 years ago Southwest Airlines had a reality TV show on Discovery channel about how terrible they were, with episodes like "They ran over my wedding dress with a baggage handler truck" and "They destroyed an irreplaceable guitar of a well known musician".

I always wondered who paid for that.


As an European who's lived in the US, Spirit was actually just as "good" as Ryanair. Sure, you can hate on both of them, but they're cheap and moce you from place to place. I can endure any discomfort for 3h if it meant I could save 100 or 150 bucks flying from NYC to Miami/FLL in high season.

I had much worse experiences with Frontier and promised myself never to fly them again. On one occasion we had to wait for 2h on the plane on tarmac after landing at MacArthur airport because... the airport staff was not responding to pilots' calls. Somehow they didn't know the plane was landing. It was 1 AM or so and while it might not have been Frontier's fault, to not be able to sort it out for 2 hours was telling. Had other issues, too, this one was most ridiculous.


The reason people hated spirit was the same reason they flew spirit, it was cheap.


My friends used to joke that it was like flying in a tin can, or that the wheels would fall off mid-flight. The jokes were endless.

I liked Spirit, though, great cost savings, and I didn't mind the minor inconveniences that came with it.

Aside from being known for being a cheap airline, the brand itself was pretty solid... I think it had everything working to its advantage. The bright yellow exteriors of the planes, a catchy name. I think people knew exactly what Spirit was and what they offered, which is the sign of a good brand.


They did things differently compared to other airlines, so it does warrant an explanation. People pay for the cheapest flight, and expect things like free bag checkin. Other airlines will charge everyone more, even if you had no bags and provide free bag checkin. I've had flights where I only had a small backpack and nothing more, I don't want to the "priced in" fee assuming everyone will check a bag. Spirit gave you exactly what you paid for, which is how it should be. No marketing mind games to trick you into thinking you're getting some luxury service. Even in first class most domestic airlines provide a subpar experience, might as well be for a good value like Spirit did. International flights are different though, and the bar is much higher there due to length of flights.


loved Spirit and flew with them 8 different round trips from BWI to many destinations. So cheap (clothes in bookbag) and never had an issue. They will be missed!


the "temu" of airlines if you will

wait a minute... what if?


Link?



Exposing the wealthy is pretty standard journalism


And if this guy isn't Satoshi?

And if he comes to harm as a result of someone believing the NYT?


Come now, don't be absurd. The NYTimes has hard hitting evidence to back up their accusation, like "He shifted in his seat when asked about this."


[flagged]


I don't think that's what that word means.


Then the person who harmed him will be prosecuted. And life will go on.

The NY Times isn’t calling for violence.


> Then the person who harmed him will be prosecuted ... NY Times isn’t calling for violence.

And the negligent driver also didn't mean to cause injury, yet we have laws on negligent driving.

If the NY Times would have known that harm could come to someone by having information published, they should consult and/or take measures to prevent that harm (or at least, take measures to minimize it).


The negligent driver was driving the vehicle though. The NY Times writer isn’t holding Back hostage and holding a knife to his throat nor indicating anyone should do that. Your metaphor is nonsense.


Consider the following hypothetical: you have a safe in your home with a substantial sum of money in it, and you consider its presence, the location and contents private knowledge. However, someone uses publicly available information to infer the rough location and contents of your safe and makes it public. You are robbed shortly after. What percentage of responsibility lies with that person?


Responsibility is entirely your own fault for letting the “someone” know of your safe and it’s value. Do you know in America most gun safes are kept unlocked? Most gun safes are rather large too, hard to hide. Why doesn’t chaos ensue when this fact is known? Someone COULD go an steal all the guns and use the guns to kill everyone then rob everyone. But do you think they’d get away clean and no one would have any idea what’s going on? It could happen but hasn’t yet.

It’s another day, why hasn’t some nut captured Back yet and done any of the fearful things you’re insinuating yet?

In fact why didn’t someone just kidnap and torture ALL of the possible Satoshis? The names have been known for quite some time. I’m sorry but your theory that revealing who Satoshi is, is bad doesn’t hold water.


Alternatively, you don't even have that money, the journalists hallucinated the whole thing, so when the home invader breaks in and starts torturing you, there's literally nothing you can do to save yourself as they cut off pieces of you little by little.

But don't worry, they'll definitely solve this crime, because the clearance rate for impersonal crimes that don't involve family, friends or business associates is famously high. ...oh wait.


So if someone broke into your house, murdered you, and stole all your money, you would die peacefully, knowing that the thief will be prosecuted?


What? They murdered me then stole my money. I’m dead before I knew I was robbed so in your scenario I can’t die knowing the thief would be prosecuted, because I’m already dead. I literally dont care what happens then because I have no agency at that point in time.


That's my point


Harm from exposure can take a lot of shapes and sizes that go beyond the physical and the potential prosecution that someone may be held accountable I find weak.


And yet they would be responsible.


How? Knowing who Satoshi is, is a great thing. Don’t create a diety out of the pseudonym.


It's pretty standard left wing activism. Rags like the NYT pretending there's no difference, doesn't mean there is no difference.


HN now has a massive boner for billionaires, everybody imagining they’ll become one someday. It’s pretty sad


Universities


What do you base that on? Some of the best names in academia are Chinese, and in the computer graphics world, SIGGRAPH Asia has largely eclipsed SIGGRAPH for academic presentations


Chinese names at American universities


Not unless they’re going right back to China. In droves.


Are you sure?


For now, but they're catching up quickly I'm sure, esp. since American university quality is surely degrading quickly.


A more accurate description of code is that it’s a depreciating asset, perhaps, or an asset that requires maintenance cost. Neither of which is a liability


“A golf game is 65-75 swings over ~5 hours.”

What about the back nine though?


This guy golfs.


They never golfed with me, double the swings and then triple the time I take to find my ball. I have the hardest time find things, not just in golf :)

So I guess I would get a decent workout by all the walking I do. FWIW, I have not played golf for over 30 years due to having a hard time finding the ball.


Beautiful comment.
