Typically, taxi medallions aren't sold by the government anymore. They're typically sold by their previous holders and the high prices reflect their scarcity and perceived value. The market decides this value (even when they're auctioned off by the state), so there isn't any guarantee that they'll maintain that value. Any contracts that exist say nothing about limiting the supply or compensating medallion-holders for any speculative prices they paid. Buying a medallion for $800k is just as speculative as buying an $800k house or $800k worth of stock. There are no government guarantees that they will maintain value.

tl;dr... The economics of the taxi medallion situation are extremely similar to shares in a company. The "contracts" that you're referring to don't exist (at least in the form that you image).

Have you ever had a LEGO brick turn squishy on you? Because that's what they're made of, ABS plastic.

It's a plenty tough enough material that I used it to manufacture parts for a geodesic dome for outdoor use as a greenhouse, and it held up fine. I also manufactured gears for a friends high end RC car after the manufacturer had gone out of business. Those gears see a lot of stress, and they held up fine.

ABS is a great material, and so is PLA.

Super Dracos are for escape in flight too, including in and past MaxQ. But they are on Crew Dragon, not Cargo Dragon. Cargo Dragon did not carry a crew and wasn't programmed to save itself.

You are confusing "ascension" with "right ascension". Just plain "ascension" (not capitalized) is pretty much a synonym for "ascent".

A few dictionaries define "ascension" as an astronomical term referring to the rising of the star above the horizon -- in other words the increasing of altitude in the alt/azimuth coordinate system -- but this definition doesn't appear in lists of astronomical terms so either this usage is uncommon or obsolete.

In our contemporary world where any sort of "promise of quality" is seen as quaint and most companies see their established brand names as something to be cashed in for executive bonuses, people are trained to not give any weight at all to brands. See the AC response for a great example of that.

Oh, well you have a feeling. I guess the scientists can pack up and move on to some other topic then.

Most of us do have a need to transmit messages privately. Do you not make any online purchases?

Yes, but those have to use public-key encryption. I am sure of my one-time-pad encryption because it's just exclusive-OR with the data, and I am sure that my diode noise is really random and there is no way for anyone else to predict or duplicate it. I can not extend the same degree of surety to public-key encryption. The software is complex, the math is hard to understand, and it all depends on the assumption that some algorithms are difficult to reverse - which might not be true.

First of all, Sir Tim is British, and second of all the First Amendment refers to government regulation of speech. It does not compel a private organization to employ or associate with an individual whose speech it feels reflects poorly on them.

This is not a legal issue, it's a moral issue. It's morally wrong to empower a social media lynch mob without performing a reasonable inquiry into the facts.

I don't claim to know anything beyond what I've read in the news, which of course doesn't qualify me as an expert. But I'm fairly confident the fact that you find the accommodations made to Hawaiian religious beliefs annoying has no bearing on whether those beliefs are sincere.

I agree that there's no way to satisfy some of these people. That doesn't make them liars or bad, it just means their interests in this situation cannot be reconciled with yours. It happens sometimes. As much as I believe in looking for win-win solutions, there are occasionally situations where one side or the other has to lose.

And you won't ever get everyone on the other side to agree because that never happens. There are even Catholics who think the Pope isn't as Catholic as they are. So as soon as there were any questions raised about the religious dimension of this project it became inevitable that if they ever built this thing it would be in the face of protests. And as long as the project's leaders think what they're doing is right they should do it and take their PR lumps on the chin. But imputing, without any evidence, false and hypocritical motivations to the protesters actually undoes the work done to make this project possible. That actually *is* disrespecting native religious beliefs.

There is nobody for whom the summit of Mauna Kea is their "backyard", so this isn't NIMBY. There are sincere religious and political reasons for opposing this.

Imagine yourself in their position. If a conspicuous structure on the summit of Mauna Kea offended your religious sensibilities when the first one went up, then you're not going to feel less strongly about the thirteenth or fourteenth to go up. Likewise spreading the development to a second, pristine sacred site wouldn't placate you.

The position that nobody's religious views should ever matter is one most people wouldn't agree with, but at least it's a principled position. Claiming (without proof) that views that stand in the way of something you want are insincere and should be disregarded strikes me as dishonest.

Most algorithms to do this use the time between keypresses, measured to very high precision so that the lower bits are chaotic. So it doesn't really matter what keys you hit, and it doesn't matter how rythmic your typing is.

The problem with FM static is that you could start receiving a station, and if you don't happen to realize you are now getting low-entropy data, that's a problem.

There are many well-characterized forms of electronic noise: thermal noise, shot noise, avalanche noise, flicker noise, all of these are easy to produce with parts that cost a few dollars.

True randomness comes from quantum mechanical phenomena. Linux /dev/random is chaotic, yes, enough to seed a software "R"NG. But we can do better and devices to do so are cheap these days.

I wouldn't trust anything but diode noise for randomness. If I had a need to transmit messages privately, I'd only trust a one-time pad.

Talking to the French about their rioting is like talking to Americans about their guns. They'll assume you're out to undermine their national origin myths.

Communism has been tried on a large scale - see Mao's Great Leap Forward.

Nope. That was a totalitarian socialist program pushing a collectivism that didn't work. Communism is a post-scarcity society and obviously scarcity was the thing Mao produced best.
