I've had this idea of feeder trains that rendezvous with the primary train by pulling along side, matching speed. Then a brief and orderly movement of passengers between feeder & primary train occurs. When complete, the feeder train disengages, slows back down — the primary train continues to its next destination.

Feeder trains bring new passengers on board the primary train. They leave the station a little ahead of the incoming primary train in order to accelerate up to its speed just at the rendezvous point.

Another empty feeder had already rendezvoused with the primary before the station and passengers disembarking were offloaded onto it.

In short, the feeders can be small. The primary train need not stop at all the points in between.

I would love to model this graphically.

And yet whenever alternate economic systems fail, and they have always failed, they turn to capitalist economics to bail them out. Capitalism has raised billions of people out of poverty. In China alone Capitalism has raised hundreds of millions of people from subsistence conditions into middle class lifestyle. Chinese factory worker wages rose on average by 64% between 2011 and 2017. That’s market forces in action. I’ve been going to China since 2001 and watched it happen with my own eyes.
> "We're in a simulation" fundamentally discard Occam's Razor in the fashion of the belief in God as controlling everything. And thus this belief has the same weight as belief in the Flying Spaghetti Monster [1].

You are using Occam's Razor incorrectly. A preference for parismony in problem solving is not identical with parsimony being the only state of the world.

As a side note, which directly applies to your comment, Occam's Razor was invented by Friar William of Ockham as a defense of divine miracles.

Just take a look at the Windows desktop versus Linux desktop. The Windows desktop is far more fragmented and discongruous.

With Linux, the main difference is whether your desktop is primarily Qt or GTK. Sometimes an app using the other toolkit will look kind of funny, but most of those differences are paved over by any competent distro (eg: Debian, Fedora, Ubuntu, OpenSUSE...).

Cryptocurrency financial crimes are often masked as a technical issue inherent to decentralized, trustless networks rather than the truth; they are issues inherent to centralized, trustful systems.[a] Transfers within the blockchain are already perfectly traceable. Perfect traceability is the reason for the blockchains being. It is the interface between the blockchains and traditional finance where this problem lies.

[a] The history of finance is the history of financial crime. Jews starting banks because of Christian usury laws, the Medici sidestepping the monetary power of the church and kingdoms, etc.
Agreed. Restaurant food is generally speaking unhealthy and overpriced. Low quality ingredients are doused in fat and salt to make them palatable and I'm expected to pay an exorbitant fee for someone to remember what I asked for and carry it across the room. It's cheaper and easier to eat real, whole foods at home. There are too many restaurants and we've come to rely on them for our daily sustenance. A healthy relationship to restaurants would make it a once or twice a month kind of proposition, yet it's not uncommon for people to use restaurants as their primary source of nutrition (don't even get me started on F-ing delivery).

The more of them that shut down after COVID and don't come back, the better.
Once you learn to cook you won't eat at anything less than the most expensive. It is really hard to enjoy a meal when you are thinking "I could have done this better myself at less cost". Chains and fast food just don't provide the quality I demand for the most part, and even the independents are hit and miss.
"Here’s the only technique I’ve found that works, which I call scrobbling even though that means something totally different:

"1. Search seed terms you know, like “cost of bugs”, in an appropriate journal (here’s one).

"2. Find papers that look kinda relevant, skim their abstracts and conclusions.

"3. Make a list of all the papers that either cite or are cited by these papers and repeat.

"4. Find more useful terms and repeat."

Congratulations! You're a grad student now!

P.S. When I graduated, I had a filing cabinet with two drawers full of papers that felt important enough to save printed copies, from just this process. A couple of months ago, I carted them out to the burn pile, threw them on the pile of leaves and brush, and held a Viking funeral. And I didn't even feel bad. :-)
Hmm the whole way bitcoin is set up is tailored to making this impossible. Anyone can write a wallet program and create a private key.

Of course when converting to Fiat money they have a chance to ask for ID but I don't see this happening with bitcoin to bitcoin transactions unless the whole protocol is changed around.
Purely from an industrial perspective, interest in formal methods tends to split two ways:

1. Verifying really nasty algorithms, the kind you see in cryptography and embedded systems and stuff where the bugs are triggered by horrific race conditions or incredibly specific malicious inputs that even experts won't think of testing

2. High level specifications of requirements and abstract machines and stuff, where the spec is like 100 lines and the implementation is 10k and you'd prefer to catch some design bugs before you're ten sprints into coding

A lot of bugs in (1) end up being memory-related, which is why you're seeing languages with borrow checking as part of the semantics (Rust). A lot of hype these days is in (2) because it's a lot cheaper and easier to learn, at the cost of having a lower power ceiling.
You're not entirely wrong. For a proprietary, closed-source, limited-access system that Apple has complete control of, it's surprisingly vulnerable and slow to be patched.

I think it comes down to a few different reasons. Firstly, SpaceX had to find profitability relatively quickly or die. Blue doesn't have that problem, thanks to Bezos' personal war chest. SpaceX couldn't gamble on the idea that space tourism would be a significant cost offset. Putting payloads into orbit was a more viable business model.

Second, New Shepard is massively over engineered for what it is. The reason for that is that they plan on using it to learn how to make much bigger rockets. Though, I suppose you could reasonably argue that the delays of New Glenn means that wasn't a smart tradeoff.

Lastly, Blue doesn't have the same laser focus SpaceX does. I think this is most likely the biggest contributor. They've made all kinds of different engines, they designed their own lunar lander, then they designed another one with Northrop, Lockheed, and Draper for NASAs HLS project.

My understanding through people I've talked to with connections to Blue, is that Blue operated more as an R&D lab for the first several years of it's existence.

I, like a lot of people, suspect now that Bezos is more focused on Blue they will start making bigger waves in the industry. At least I hope so, because I'm really excited to see competition in the space!

starlink is low enough that it will clean itself /relatively/ quickly, but even doubling the elevation get's into some very long lived debris[0].

If you wanted to tax these mega constellations to mitigate the externality they're causing, directing 2 to 3% towards orbital telescope production/launch costs arguably would be the most immediate remedy.

The root context of this discussion is basically whether or not it makes sense to add in intermediary stops on a rail line. If you're insisting that people have to be seated and have no drinks out for every intermediate stop, that rather sharply raises the discomfort level of stops. Another unpredictable element of train acceleration is the need to slow down to negotiate a curve, which isn't necessarily the case only in the immediate vicinity of a station.

FWIW, the numbers I generally see bandied about for acceleration on (decent) trains is about 1 m/s^2.
Part of the reason for that is that Blue Origin's flight was about 12 minutes in total, while SpaceX's first manned mission was closer to six months.

Sorry to disagree. The interaction you see in the page is not scroll snapping.

With scroll snapping you the user have always control of the scrollable content. What you do not have control over is where it will stop scrolling. A similar behavior to forced guides in a movable element on rails (such as drawers).

This page doesn’t scroll at all, and uses the scroll as a time control for a “movie”. And that is scroll jacking, as it hijacks the scroll position to do something completely different.

This page, at least on mobile, is also guilty of implementing it in the worst way possible: without any alternative scroll indications and without smooth continuous transitions that make it clear that you are controlling the animation through the scroll.

Apple is somewhat better at doing this since the scrolljacking procedure usually brings you to an element which, at the end of a glamourous entrance, actually scrolls away with the page.
> I'd go even further and say it'll be a net-loss in most cases, especially with modern complications like heterogeneous compute. If you're use case is specifically spinning up thousands of threads for IO (aka, you're a server & nothing else), then sure. But if you aren't there's no win here, just complications (like times when you need native thread isolation for FFI reasons, like using OpenGL)

Virtual threads are going to be an /option/, not a requirement. Threads have to explicitly created as virtual threads. If this is not done, nothing will change.
Most of the historical community building was done at faith communities, and by stay-at home parents in the past. As a society we fell hook line and sinker for "The two income trap," and are unwilling to contemplate the horrible idea of allowing families to collect the childcare subsidy to pay the parent providing childcare is upsetting to enough different groups to be a non-starter.

Right wingers are upset because "it's socialism" and folks on the left who I've discussed the idea with have repeatedly expressed fear that it will undermine feminism.

It could also be that your understanding of neutron stars may be superficial - you may feel, however strongly, that you understand this topic, while reality may be different. Have you considered that hypothesis?

Nobody who actually works in fields related to nuclear physics or astrophysics considers a neutron star as being "just a giant nucleus", no matter how often that image may be used in pop-sci articles and youtube videos.

More linky stuff, again related to your statement that neutron stars are held together by the nuclear force (which is false):

https://www.nuclear-power.com/nuclear-power/reactor-physics/...

> Since they have some similar properties as atomic nuclei, neutron stars are sometimes described as giant nuclei. But be careful, neutron stars and atomic nuclei are held together by different forces. A nucleus is held together by the strong force, while a neutron star is held together by gravitational force.

I forget where I heard it, but someone once said "The mind is like a boomerang. If you throw it, there is a very good chance it won't come back."
I think the issue is that management is not done scientifically. You can see this with something as estimating for a project. Higher ups just ask “how many hours and when can you get it done” - they don’t want you to go through past similar work review it’s timeliness and hours, divide it into smaller tasks, build a project schedule, review productivity trends and resource loadings, or any scientific way of arriving at the number. What they really want is a seat of the pants WAG, which isn’t too big to scare the client, that they can use to get going, with the understanding that shit happens along the way.
I got into software specifically because I didn't want to go to physics grad school, and now I read more papers than I ever did in physics. Man plans, God laughs.
> More people dining means more profit probably.

I gave a precise argument to why I think tips do not increase demand for the service - most people in the US, regardless of wealth, pay at least the minimum tip.

GP's argument that there is a substantial price segmentation would only hold if poorer people did not pay the tip.
Jeff Bezos reaches space on Blue Origin’s first crewed launch
This will sound esoteric, but I feel should say it: sometimes when you are involved in a practice for which you have no context, you will open a door to things for which you have no name. You won't be able to name what you see or what you feel, and this can cause everything to come crashing down. An experienced guide can help you avoid this outcome.
I'm curious where in the US are healthcare workers getting less than $15/hr and what kind of work it is. Even the sort of jobs that require no certification, no degree, and no experience seem to pay quite a bit more than that.
New Shepard landed after going to space nearly a full year before SpaceX's first landing.

Obviously an orbital class booster is a different challenge than a suborbital booster, but the idea that Blue is copying SpaceX is just wrong.
Yes, BUT the correct thing to do would be more tedious to write that way.
> And that it’s possible that these things have conspired (unknowingly) to make sure that my detector settings and a particle’s spin measurement is correlated in a particular way in my lab in a law-like way.

Yes exactly, which is to say that your instrument calibration dicated by that elaborate randomization process, just ensures that the particle will arrive in a specific configuration, which is a purely local, realistic phenomenon.

Sabine and Palmer recently explained how superdeterminism can be understood easily as future input dependence:

https://www.frontiersin.org/articles/10.3389/fphy.2020.00139...

Edit: despite superdeterminism annoying you so much, I bet you're perfectly fine with general relativity in which time is just another space-like coordinate, and the correlation you describe is a perfectly well-defined path along a closed timelike curve. An interesting inconsistency if true.
>The new rules would also prohibit providing anonymous crypto-asset wallets.

As a business/service, or in general? If the latter, then it's literally a ban on cryptography.
To be clear, it would be ChessBase that would be sued, not individual users. And ChessBase would be the one allegedly in violation of "distributing it, making copies of it, and violating contracts". Since their license to use Stockfish seems to be revoked, it seems like it would fall under copyright infringement at that point (although up to the courts to decide, of course).

Singapore, Switzerland, the UK, Denmark, Germany, and the Netherlands all have wildly different healthcare systems, but all produce fairly good outcomes!

What was Jeff Bezos' carbon footprint today?
As an Australian living in America, the expectation that there will be a person to refill your water cup is pretty uncomfortable. The need to tip is a ridiculous abdication of the responsibility for labour laws to ensure staff a living wage. If you don't like the service at a restaurant, don't go! There are other restaurants that will compete for your custom. If no restaurant is sufficiently servile for your tastes, then your expectations are likely out of step with local culture and how it treats people.

Individual service persons should not be held hostage to your interpretation of their service for their wage. If they're routinely underperforming they'll be sacked.
I might just be not lurking in the right corners of the internet, but is there a specific reason for serving HTML over FTP vs serving HTML over HTTP?

Not allowing FTP subresources on HTTPS is basically the same as not allowing HTTP subresources on HTTPS, that is just logical.
>I’m a pretty technical user and use the web and the internet a lot.

Oh Wow! cool! I'm so impressed!

So what you're saying is that because you "use the internet a lot" that you know everything about the requirements, hardware, software, and most importantly limitations of every single internet user on (and off!) the planet.

I guess I should at least give you some credit for not having any problems with self-doubt.
New Zealand accuses China of cyber attacks
Also look at how many chain restaurants are structured in their financing and it is not great. Usually some portion (40% or more) of the net goes to the parent corp. Then out of that you pay the lease on the building, any required decorations, and buy from locked in vendors. Both all owned by the parent corp or some sister corp. Then out of what is left you pay your employees, taxes (on the net), and yourself. You are looking at maybe 10-15% of the net to do that with too.

People can say 'oh just make the wages better'. But that may literally be the difference between there being a restaurant and nothing at all.

Many gas stations run the with the same model. The twist is the gas companies own the land, and the pumps, and set the price. You just run the business.

Basically most of these places someone 'bought a job'.

Think I heard somewhere that places like McDonalds is one of the largest land owners in the world. Yet most of their stores are not 'corporate'.

I don't see what's stopping the US from building elevated rail over interstate highways. They already own the rights of way, and the radii of curvature are already pretty large. As a conservative lower bound, they should at least be able to match automobile speeds.

Additionally, those highways typically enter cities, so stations could be built over them, often right in the city center. That does leave details about how those stations are accessed, but this seems minor since everything else has already been dealt with.

I wonder if an executive order could make it happen.

I'll confess that, like the Fielding dissertation, I also can't make heads or tails of this comment.
Not really, I got answers wrong more often than some other students, but I had a skill none of the other students had after I switched schools. The ability to think about math. I've always had a cavalier attitude about the "correct" answer, being able to think in my head and come up with approximate answers is more important. I still think the teacher was wrong to mark my answers incorrectly when it was clear that I was turning my papers in minutes faster than the other students and only having a margin of error within 5%. That ability to think about problems in my head wouldn't have developed if I wasn't afraid to get an answer or two wrong in the pursuit of intuition. It's no different to me. Even in my work I'd rather get the approximation first, than shoot for precision later. I think that's an attitude that gets lost in the mix of precision first. It's certainly an attitude I took into adulthood that has been a boon to me professionally. When I'm writing software, the first step is do it, the second step is do it better and the third step is do it right. Imagine trying to write an entire software application and having it work perfectly the first time you build and execute it. If we can't achieve that kind of perfection in our work as professionals and adults why would we force it on our kids?
