The original preprint said at least 400K. They didn't find an upper limit. And for some reason, they don't seem to have the standard impulse of "hey, our potentially revolutionary material that we've been working on for

It's useful for the dozen people you're transporting, but transporting a dozen people isn't exactly worth building a train system for. The economics only make sense if you're hauling around masses of people, and you can&

But the cultural expectation has shifted. AFAICT, it is now expected that people will cheat as a matter of course. That may have happened because of past leniency, but at this point expelling students is shutting the barn door after the hor

Yes, normally when people come up with some BS about room temperature superconducting, they really just mean they've observed one of the indirect effects of superconductivity. "If you put an ohmmeter in my funky circuit, it displa

Uh no, I'm pretty confident they are just saying that whatever the Tc is, it's at least 127°C. I don't think they're redefining Tc to mean that it superconducts above that temperature. That would be... interesting. &qu

So you're saying it could be a great sensor, similar to a Josephson junction? :-) Update: "yes", from the paper: "The Josephson-like phenomenon for the under-damped junction of superconductor-normal metal-superconductor(

I was just in Paris. It was a major eye-opener for me to observe people on the Métro when there was a train approaching while I was a little ways away from the platform. Very few people rushed to make it! It initially made me doubt that I u

Yeah, when I was thinking about the hash, I thought of it as stuffing to fill the unused portion of the number that would look better than using zeroes. TIMESTAMP010111101010101TSC "looks better" than TIMESTAMP000000000000000TSC e

The English version is "you catch more flies with honey than with vinegar", which at least in English makes more sense, since in English "sugar" generally implies dry granulated sugar. You're not going to catch any

This is brilliant. Often, people will come up with clever-sounding ideas for how to "fix" some part of the internet. "Just let people do X and it'll all work out!" The movie generated by this project is a perfect il

Whoa, you're right! I know it used to be a problem, since I told several people about the feature, they tried it, it didn't work, and when looking at it I realized they were leaving off the space (or I hadn't even mentioned i

It would be nice if the author could fix this page, since the examples are incorrect and do not work as written. You need a space after the magic character. Although I use it exactly as described (prefixing my search with the magic characte

It's not whether it's "wrong" or not, it's just a question of whether it aligns with your goals. If your goal is to maximize the amount of money you make from a venture, there's nothing wrong with it. There&#x2

I think the conclusion is justifiable, but it relies on the author's definition of "destroy". "If you want to run a company that looks like X, then taking VC money will prevent that from happening" is a pretty easy

Good point. > VC makes sense if you can grow fast and very large. I could also argue that such companies are often a blight on the ecosystem. They're an invasive weed that outcompetes a rich variety of smaller companies, sucking the

Ok Climbing up the stairs directly burns 2 calories, and not eating the Oreo because you're climbing the stairs avoids 53. Sounds about right to me. Even if it does require living in one of those places where it is not customary to sto

Your point flies in the face of decades of evidence in the field of cognitive psychology. Our brain is not defined as "that which makes decisions". Brains do many things, in many different ways, and the vast majority does not invo

Sorry, I was being too indirect. The whole intro section is weirdly selective about what to include and weave into a single narrative. I lived through that time. There were a lot of other things going on that paint a different picture. Not

Well said. I enjoyed watching the best show of all time. (Of course I did!) Up until Firefly got canceled, anyway, which was enormously frustrating. But at least I got to keep the sense of mystery and the potential of big reveals. Then they

Having been involved in at least some degree over that period, yes there is a large difference. Not a simple one; there are both good and bad differences. (I would guess that the raw amount of open source code produced today is rather large

Great article, but it did give me the "an elephant is like a rope" feeling—it seems like it's one person's idiosyncratic perspective, some of which I agree with and some I disagree with, and there isn't really much

Further offtopic, but I have Windows programs from the 90s running fine on my machine, but only because they're running on Wine on my Linux box. Windows itself can no longer run them, even in compatibility mode.

The cities and the countryside, actually. In rural areas, you may spend most of your time in your own territory, but when you encounter other people they'll probably stop and chat. (For one, when your cows get out and into your neighbo

Yes. In the younger circles, it seems like there's a very brief period of telegraphing your "tribe", and once you detect the matching cues you can assume you know pretty much everything about the other's point of view.

True, and as you get better at it, those hours will be fewer. The weeks of debugging never go away, though. (Or at least, not as long as you're using shared state, but that's really the only thing under consideration here.)
