> In popular scientific writing, neutron stars are therefore sometimes described as "giant nuclei". However, in other respects, neutron stars and atomic nuclei are quite different. A nucleus is held together by the strong interaction, whereas a neutron star is held together by gravity. The density of a nucleus is uniform, while neutron stars are predicted to consist of multiple layers with varying compositions and densities.

It's just a pop-sci meme.

As for the structure, see here:

Yes, I was speaking of country-scale. Specifically, countries the size of the US, which are few and far between. This is not possible at country scale in the US.
I'd so much rather my case be heard by a group of qualified judges (that's right, group. Your case is heard by three judges, to make sure no one judge gets to manipulate a case on a whim) who got their job because they were appointed based on their career track, rather than because they were elected by an electorate who hasn't the slightest idea how insane that is. (lawyers need to be bar-qualified, but judges amazingly need zero qualification. Wtf, US?)

And that's before we actually look at the reliability of a jury trial: the letter of the law might claim it's a jury of peers, but that's never the case from the outset, and then lawyers get to demand that the only people who might actually do any reasonable thinking get replaced if they know a reasonable thinking person would conclude their client's guilty.

The system is so messed up, you could write multiple books about it. Which people have.
What does "otherwise throw an exception" mean at the CPU level?

I know Erlang's BEAM VM has a "fail jump pointer register", where instructions that can fail have relative-jump offsets encoded as immediates for those instructions, and if the instruction "fails" in whatever semantic sense, it takes the jump.

But most CPUs don't have anything like that.

Would you want it to trap, like with integer division by zero?

CPU traps are pretty hard to handle in most language runtimes, such that most compilers generate runtime checks to work around them, rather than attempting to handle them.
As a counterpoint to this, it is possible to scale existing airports up to meet consumer demand as-needed. There are thousands and thousands of airports in the US, but most don't have passenger service. Example: Paine Field in Everett (north of Seattle) became a commercial airport in 2019 to service an exploding Seattle metro. While it takes some time for regulations, it's straightforward compared to the billions needed to connect new cities with HSR.
Hey HN, my name is Adish Jain & I am building Leaf. Inspired by Stripe's API documentation (https://stripe.com/docs/payments/integration-builder), Leaf is a no-code tool which helps anyone author coding tutorials in a similar side-by-side format.

Leaf has a code editor & image selection block in the right pane. In the left pane, you are able to write out the steps of your coding tutorial using Markdown. You can then associate your steps with parts of your codebase / certain images, so that when you scroll through a finished tutorial, the code editor automatically scrolls to the relevant code & image.

To get a sense of what a completed tutorial might look like, check out this example of creating a CSS toggle switch — https://getleaf.app/daily-dev-tips/creatingdaynig-3219ec7d. Here’s another example of how a Binary Search algorithm explanation could look like — https://getleaf.app/dsps301/binarysearch-kchl1gs6.

With Leaf, you can go back & forth between the two-panel view and a standard blog post format view (see Binary Search example above). That means you can write any type of standard blog/article using this tool, but can additionally choose to include the two-panel view when conducive to getting your point across. Right now, we support just the interactive coding blocks / image blocks, but the plan is to add other types of interactive components such as maps & animations in the future.

If you’re interested in authoring a tutorial in this way, or just want to check out the user interface a bit more, sign up here: https://getleaf.app/signup. For more examples, check out the explore page: https://getleaf.app/explore.
It can't be used to send a message because all you can do is measure your particle. Even if doing so changes the state of the other particle far away (which isn't really what's happening, but that doesn't matter), all the other person at the end can do is measure their particle.

Neither of you can choose what the state of either particle is. You have no control, so there's no way to transmit information.

What you can do is agree in advance that you will both take certain actions based on the measured state of the particles. There's no way to be sure the person at the other end actually does so though.

Why would I bother hiding the malware in weights that are actually used by the model? Couldn't I just define a big weight tensor of the appropriate size to hide the malware, declare it part of my model, but never actually make use of it? The paper says:

>To ensure more malware can be embedded, the attacker can introduce more neurons.

It seems like it would be extremely foolish to put the malware in neurons that impact the output if I can just make my own neurons off to the side and get a 0% drop in accuracy!
Agree, I think the smart move for SpaceX is to stay ahead of it by offering/working out/subsidizing assembly line style space telescope production and launch w/ benefits to impacted astronomy programs.

I mean imagine if you just enabled a high quality ~cell phone camera in each direction on the existing starlink array etc. Or what if starlink specified a parasite satellite slot that they sold e.g. you can put up x mini sats embedded and facing space with network and power port. It lasts as long as the node lasts, put up a lot and don't complain.
Axioms are most certainly not true by definition.

Regardless, the particular technical definition of truth I'm using is Tarski's definition of truth[1]. We don't have to agree whether Tarski's definition is "correct", and I'm happy to qualify my use of the word "truth" here, but I'm referring to a specific technical definition here.

White label providers is a thing, there's only a handful of operators doing the actual banking/payment services behind that.

>They are identical in every way, except one is red and the other is blue. I randomly grab one in each hand and show my hands closed. Now the states of the ball are entangled: as soon as you see the color of one ball, that "determines" the color of the other.

This gets used to explain entanglement but it really has absolutely nothing to do with it. This is nothing that the ancient Greeks wouldn't have known.

Not to pick on you specifically, but do people really think it took a major revolution in physics in order to understand that if there are two balls, one is blue and one is red, then if you see one of the balls is red, you can conclude the other ball is blue?

It's something that I think humans can solve at the age of 3.

The failure in your explanation is right when you state that "one of the balls is red and the other is blue". The entire point of entanglement is that such a statement is not possible, that's a strictly classical interpretation. Rather, both balls are in a superposition of being both red and blue simultaneously, and it is not possible in principle to assign a color to either one of them until the moment a measurement is made.

I definitely feel bad for the guy, and I hope he got/gets the full help he needs.

That having been said, I think there's something about meditation traditions that come from and are part of monastic traditions vs. meditation techniques that have been removed from their monastic roots.

Basically, he was meditating at monk-like levels, and if he were actually in a monastery, he would probably have gotten help at some point beforehand. Maybe he was neglecting part of his health, or emphasizing one technique over another without being fully-rounded in his approach, or a number of other similar things that would have been caught by a community/teacher in a monastery. They literally have hundreds of years worth of meditation troubleshooting under their belts, though some of it is codified in ways that directly intertwine with religious beliefs/practices.

But when you try to remove the practice from the culture surrounding it, there's a danger that you left behind some important pieces. I find it kind of scary that he mentions there are recovery groups and such, especially for meditation teachers. I mean, it's awesome that they're supporting each other and recovering, but this seems like a red flag that maybe the a-religious form of meditation as it's being taught and marketed right now needs to go back to the source and figure out what monks are doing differently, or, even better, make sure they immerse themselves deeper into the source cultures to be able to troubleshoot adequately.

I guess it's like eating an olympic athlete's daily meal while ignoring the rest of their training regimen as "religious superstition" and getting drastically different results and being surprised.
It's a Western problem. China just moves people out of the way. In the West, you have go around, under, or over. Labour costs are low. The CCP answers to itself. Can I build this? Of course you can!

In the UK, there's archaeological surveys, bio-diversity/green considerations, carbon impact, political lobbying. The list just goes on and on and on.

The US, at least, is largely an empty continent. You can probably draw a line between cities and not hit many things. Plus the US love-affair with cars means you could, if you wanted to, build terminals outside major cities and rent a car to drive the last part and still conceivably run a profitable service.

In the UK, we must have our terminals in the city centres which adds so much more to the cost as we have to tunnel under and into the cities.

If your "ideas man" has fully committed to doing all the sales/marketing and the dance of raising capital, leaving you to work on the product, I think that's a very fair division of labour. After all, a finished product is almost as worthless as an unexecuted idea if no one ever actually purchases or uses said product. I say almost because, in theory, your product could have enough "obvious" value on its own that you could just sell it to another company and exit comfortably.
I think you misinterpreted my comment (probably my bad, Im not an English native). What I meant is: It is important to make sure that the profits of stocks sold need to be taxed properly, and only the after tax amount that’s left over can be spend on, some may say frivolous, space adventures. Especially when it is often reported that billionaires dont pay hardly any taxes, since their wealth grew „only in equity“. But then suddenly they find themselves on a pretty expensive space vacation.
Absolutely true.

... but since we live in the era where multiple agencies have already done that, it's possible Bezos's dollars would be better spent on combined efforts with one of the front-runners to do something more ambitious than yet another capsule to high-altitude ballistic flight.
I mean, you could have had this for a long time already if there were political will. This newly unveiled Chinese train is based on decades old German tech. They tricked Siemens into building them a "test track" in Shanghai ages ago, with the promise of giving them a contract for longer routes. Now they have the tech and plan to build it themselves.

Btw, other countries determined the maglev tech to be uneconomical. I think India and Saudi Arabia and some other places were interested but ultimately nothing became of it.
> I think portals are perfect for this use case because, as I said, you can create portals across different documents.

Many of the documents I'm consuming are PDFs, but I'm typically creating documents that are not PDFs like source code, Markdown/HTML, or schematics (the latter may eventually be exported to PDF, so the approach does have some merit). That's why I'd like a portal or bookmark to open/change focus to the app and jump to the target in one click from outside the document.
what's your inflation % ?
Great comment. It's just not practical to have two systems. Too expensive. Too hard to get anyone to sign off on both. Both take a lot of public money and it's hard to get people to duplicate spending when the other thing is "working." Worse is better, to use software speak!

I wouldn't trade our Interstate for anything, either and anyone who says that the roads outside of Paris are anything like US interstates just hasn't been on the latter. Anyway, I also love European trains and have spent lots of time on those. The benefits of going from Métro in France for a day trip to Belgium, then back to Paris in time for dinner is just fabulous. No car. No luggage. That is simply not happening in the US.

Regions the size of the Earth do not "flash freeze" rapidly enough to stop waves or animals in their tracks. Radiative heat loss to space is simply not that efficient. Human-engineered flash-freezing works through direct contact with cryogenic surfaces or liquids, and even that takes hours.

https://en.wikipedia.org/wiki/Flash_freezing

Your link directly contradicts the "heaping pile of evidence" of rapid shifts, and the proposed theory is not one of sudden (in a matter of seconds, or even centuries) shift, but at the order of millennia. Even that rate of movement has no supporting evidence:

While there are reputable studies showing that true polar wander has occurred at various times in the past, the rates are much smaller (1° per million years or slower) than predicted by the pole shift hypothesis (up to 1° per thousand years).[2][3][22] Analysis of the evidence does not lend credence to Hapgood's hypothesized rapid displacement of layers of the Earth.

https://en.wikipedia.org/wiki/Cataclysmic_pole_shift_hypothe...

Anyone can propose a hypothesis.

Demonstrating it to sufficient degrees of robustness to be widely and generally accepted is another matter.

Note that this does in fact happen, as in the case of another geological crackpot theory now accepted as not only fact, but the core theory of all geology: plate tectonics. This occurred over the course of 50 years as increasing independent lines of evidence all pointed at the same conclusion:

- The correspondence of shapes of numerous continents.

- Similar geological formations and fossil records in now widely-separated regions.

- An understanding of the atom and nuclear chemistry, giving rise to radioactivity, the thermal engine driving geotectonics.

- Seismic observations of the Earth's interior.

- Seafloor surveys, including evidence of magnetic pole reversals, giving a timeline and estimate of seafloor spreading.

- Evidence of extrusion and subduction.

- Widely correlated zones of tectonic and volcanic activity.

Those are measures of proof that are sufficient to establish a given scientific (in this case, geological) fact and theory.

>For example, we'd have the capacity to eliminate hunger if it wasn't for the pesky problem of inequality, and billionaires aren't exactly lining up to help out with that.

Hunger is basically a non-issue in all developed nations. See all the gray and purple nations on this map. In the US, for example, deaths from malnutrition are ~,1% of all deaths annually. Any money the billionaires might put into it would be better spent on traffic safety, reducing cardiovascular diseases, or researching cancer, and those are all by several orders of magnitude. https://www.worldlifeexpectancy.com/cause-of-death/malnutrit...

Also, aid sent to the countries that do have hunger problems (like much of sub-Saharan Africa) has simply crashed their agricultural economy, making the issue even worse. Local farmers can't really compete with free, after all.
“capable of reaching 600 kph”

So I take that to mean it has never actually done it, but it “could”? Before getting excited about this, maybe we should wait until the system, including the track, is actually built? Or at least a test track with curves etc.

I am not shocked this came from chinese state media originally, it comes across as a press release.

Is it reasonable to say the universe might be superdeterministic, but in the example of choosing measurements for an experiment(or almost any other example imaginable), it might as well be truly random as the causal links affecting the instruments isn't likely to be 'conspiring' in some way to impact the results of the experiment?

e.g Anything could be predicted with absolute knowledge of the starting state of the universe, and infinite computing power, but in most practical cases the causal connections between seemingly unrelated objects is irrelevant and as good as random?

> For example, no one cares about screws, as long as they are machined according to spec, and torqued correctly during installation. The chance that a random screw to bring down a whole machine is close to zero.

This sounds like people do care about screws. You identify two specific failure modes: they could be machined incorrectly, or they could be torqued incorrectly during installation. In either case, it is entirely possible that a single screw could cause the whole machine to fall apart (depending on which screw fails).

Software is very similar. The smaller the function, the fewer things that could possibly go wrong (similar to a screw) but there's always the possibility that something goes wrong. Like screws, some functions won't do much harm if they're wrong, but some are keystones that, if they fail, will bring the whole thing down.

"He could do this, that and the other thing." Well thank you for telling him what he should/could do with his money.

That's right. Up until we have 100,000 people living in space we are just winging it.

Winner of the race will be the dominant company in said community of 100,000 or the most socially influential person.

The only difference in quantum physics is that there are actually two parallel universes: One in which you took out the red marble & one in which you took the blue one. You don't know what universe you're in until you look at the marble, but still it doesn't help you to transmit a message to your friend.

I don't think it is helpful to talk about multiple universes, that makes a strong implication towards a many world interpretation. It is better to say that the difference is that in the classical case the decision who gets which marble happens when one of the marbles is taken out of the pouch while in the case of entanglement we do not really know when the decision happens but it does provably work differently than in the classical case. It might be that the decision is never truly made, that both outcomes happen in two parallel worlds, it might be that the decision is only made when one party inspects their marble, it might be that it happens at the same time as in the classical example, ...we don't know.
