Every time I see a restaurant with a line I think of the Nash equilibrium.

If there's a line, your prices are too low. Period. If people line up to buy BMWs, the price for BMWs are too low, and they (BMW) should soak people for however much they can. What part of that is childish?

If many people stop buying BMWs, they're gonna have to adjust prices or cut component costs.

I think the restriction should be limited to the hostname, but I agree with you in principle. There are legitimate use cases of using unicode characters in the rest of the URI. East Asian languages web sites for example can use the extra SEO for having an article's title on there (like English articles).

But indeed, there's no reason we need unicode in the hostname/any domain names.
>There are undoubtedly attacks still to find but Amazon is definitely not being clueless about this.

They likely have people watching the cameras full-time and will just report you to the cops if they see sleight-of-hand, now with identification and an address since you have to show your Amazon account when walking in. This is probably forever tenable to the bottom line since they're eliminating cashiers and security folks aren't paid that much more than cashiers anyway.

There's also probably a healthy amount of resolution and numerous camera angles that it'll be impossible for your face to not be picked up. Even using a fake account, you're still likely to have something Amazon-related installed on your phone that can be traced back to a telecom account.

And really, none the effort to avoid getting caught/traced is worth it to steal some bags of chips.

Unrelated to this article, but concerning the government's anti-monopoly crusade against Microsoft in the late 90s (which is relevant because many circles are unfortunately exploring government intervention against tech) ...

One common narrative is government intervention proved irrelevant because Microsoft missed mobile and the web anyway.

This is correct for mobile but wrong for the web.

Imagine no government intervention around the browser. If Microsoft controls the browser, and essentially the search engine, does Google enjoy the same trajectory? It's possible, but improbable.

Incidentally, mobile probably looks different with no Android, with Apple possibly even more dominant. However, this mobile assertion is more tenuous because it's two hypothetical steps away from non-intervention.

Whether intervention is right or wrong is a separate question altogether. But to claim that intervention had no practical effect on Microsoft undermines the pursuit of the right answer.

Breaking social dependency
A question I have always asked. The answer can be scary because often it isn't "from customers buying the thing we're making", not even close.
That's just objectively false.

Other fields use the words profit, not just accountants. Economists and philosophers, at the very least, have a claim to it too, and they do not in any way conflate the meaning with the accounting definition. Indeed, we would argue that the accounting definition is the one that is conflated with the thing we actually care about (which is why the phrase "paper profits" even exists).

And its also quite clear he didn't "conflate" the meaning, but used it exactly as intended.

Most people, I'm assuming, can quite clearly see that he captures the idea that surplus value/revenue, of which the resulting wages are a non-deterministic and variable part to some degree. That upper management of the firm take a percentage of this slice of the pie, whilst lower down labour also gets a slice, and that the notional "social justification" for why upper-management gets a greater slice is being white-anted away as the lower downs are supposed to take on their responsibilities without commensurate compensation.
Sorry, I thought the video made that clear. What is now thought is not an answer, but a perspective on the question. That the way to resolve the paradoxes between quantum mechanics and general relativity is not to find a quantum mechanical theory of gravity, but that both quantum mechanics and spacetime must emerge together from something more fundamental. In this sense, it is now thought that spacetime is not absolute. This sentiment appears widespread in the physics community, but as to precisely what this more fundamental theory should be, that answer has not yet been found.

The revolution is more about Amazon getting into grocery shopping. What they are hoping to do with this concept is to create an automated store that can be supplied via there warehouses. So that with minimum effort they can run grocery storefronts all over the United States and take over that business as well.
Everything is free software and available at https://github.com/excamera . Not sure what you mean about binaries -- afaik we only have source code checked into our repos.

It definitely will. Self-checkout is widely available in Europe. The laws about data and privacy will be different but this is a customer experience / labor cost play, not a ploy to get data.
All the money the company disburses, whether it be bonuses, profit sharing, or salary, all comes from the same checking account.

Trying to infer an injustice by the what the check is called has no point.

The purpose of accounting is to organize and understand where the money comes from and where it is going and where it is allocated, and to compute the tribute owed to the government. But a check written to someone is a check is a check, since money is fungible.
True but they also get to not share in any losses.
Just save your containers from your last visit, bring them with you in your shopping bags, pull an item off the shelf and replace it with an empty container from your bag so that it looks like you changed your mind.

It's (obviously) a function of store design, staffing, and demand.

FWIW, in Basel (Switzerland) there are often large queues at the weekends/late evenings in the (only) two supermarkets which are open, despite self-checkouts. They are relatively small stores near the station, and serve very high demand driven by Switzerland's opening-time restrictions.

Tangent: had a similarly disappointing experience with Coinbase. Not worth going into details, but I walked away feeling like the application wasn't taken as seriously as I would have expected.
The article didn't state this was related to Whole foods besides stocking some product. This could be done completely independently.
Here in Amsterdam I can step into the supermarket, pick and scan items with my phone, put them on a bag, pay with contactless and leave without any human contact. I’ve been doing this multiple times a week for the past 4 years, so nothing new.

I think you’re dramatising what is a natural step as shopping evolves with technology. If you value social interaction you can always spend more time with friends you appreciate, go to public spaces, head to the bar. The supermarket has hardly ever been a source of good times anyway.

Do not assume that you necessarily need to make things much more complex in order to scale to a thousand users. I have several client projects running on flask + sqlite.

There are ways you could simulate a lot of users at once, if you're worried about it.

If it's a "trivial point" why is this article hitting the front page? Why do you feel the need to turn a "trivial point" into a discussion about motivations and my supposed mis-assumptions of those motivations?

This article is hitting the front page because some people think it's impressive. I don't think it's impressive nor do I think it's solving any real issues. I pointed out in very neutral terms why it's not solving any real issues, but some people some to feel offended by my pointing out a "trivial point".

Yeah, marketplace is great for "interpersonal interaction", except for tourists or people unfamiliar with the societal norms of the market. In that case, they're often getting ripped off or slowing down the process for everyone. Not as relevant for supermarkets but I think the overall trend of seamless and transparent transactions make (almost) everyone's lives better off.
I'm not in the US, but yeah, the supermarket experience here is not a social event. In fact, cashiers will get annoyed if you start making small talk.

My small local corner store is different, but then again they won't be replaced by an app anytime soon, exactly for that reason.
I am not disputing the fact that high school matters as far as gender distribution of people applying to software eng. positions.

I was replying to a comment that says:

> the goal here I suspect is to get enough corporations onboard such that schools (k-12 and undergraduate/graduate) are now motivated to select for and encourage balanced talent pool participation for fear of missing out on "hip" companies

And asking how will "fear of missing out" motivate k-12 schools to get more girls into those classes. Companies don't recruit in k-12 schools.
How would duolingo and "other hip companies" recruiting exclusively from universities whose CS classes exceed a gender ratio threshold influence k-12 schools?
> Now just cut out the HFT frontrunners and I can actually the price I see on the terminal.

High frequency trading is not front-running. High frequency traders 1) do not have a fiduciary duty to other traders in the market, which is a hard (and definitional) requirement for front-running; and 2) cannot see a retail investor’s order before it is executed on an exchange. They can only alter their prices in reaction to orders that have already executed.

> I didn't say abolish the exchange, I said make the data open, generally available so I can see for myself whats going on. Also smart order routers are there already, so no I don't have to write them again, every other broker already offers them.

1. This data is already available for purchase. There’s nothing intrinsically preventing you from acquiring it as an individual. I’ve personally purchased this data as an individual.

2. Even if you can “see for yourself what’s happening”, without the extremely fast market making provided by HFT you’ll be waiting significantly longer just to find a trading counterparty. Your proposal sacrifices the liquidity and price efficiency provided by HFT in exchange for freely available market data, which the vast majority of retail investors will not be able to use (let alone want to).

3. Smart order routing is possible because there is sufficient inter-exchange liquidity. In fact, it is directly facilited by HFT.

I’m not often this blunt on Hacker News, but in this case I think it’s warranted: you do not appear to have even basic familiarity with what you’re criticizing.
I think the word is "provincial". Thanks for making that connection for me, that our lack of personal interaction is leading to the extremely polarized views we're witnessing.

Chili, interesting. I tried breaking up a Beyond Burger patty so I could use it as ground beef filling for burritos/pasta. It was pretty much a disaster. Even when cooking the burger normally there is very little room for error, compared to real beef.

I think the end-game for these companies should be to produce a chuck substitute that is malleable rather than being restricted to patties. And of course it shouldn't ruin easily.

The value I can deliver is strictly limited by the sales department these days. In the last four years, I have increased the value proposition of the business 100x-1000x (hard to know for sure, but not less than that) with my team's contributions (team of 2), yet I have not gotten a raise. No matter what I do, if we don't sell more, the value does not increase. So why should I care about the value I'm delivering when it does not affect my pay whatsoever?

Let's face, it almost all jobs are like this. Certainly all startups that are running on others' funds. Certainly all big corps. The author here is talking about a very small percentage of companies where individual contributors can actually contribute to the value of the company and the company reciprocates in value to the employee (pay). The one company that I worked in where this was the case, gave decent single digit raises. Hardly commensurate with value, but not bad.

In other words, there's no reason to focus on value provided for an employee at most companies because such focus is either unrewarded or almost unrewarded.

Amazon Go had very little to do with Whole Foods.

It may, one day, but to link the cost of buying Whole Foods to the cost of development of Go is inaccurate.
> Other fields use the words profit, not just accountants.

Sure, but we're talking about accounting here when discussing business profits. People are free to make up their own definitions of things, but that makes sensible discussion impossible.

Your comment is spot on.

Being in line at the DMV is probably the best example I can think of this.

I'm usually waiting for a while, and chatting with whomever is next to me. Not unusual to be an interesting conversation with someone I'd have never otherwise spoken to (and probably vice versa).
I'm sure there are lots of clever ways to trick the system, but do you really want to try that when you're under constant and ubiquitous surveillance and you had to reveal your name, address, and credit card number to enter the store?

I'm trying to read your whole comment, it's interesting especially since most hackers are somewhat self-taught and there are many fields we can become proficient in (such as dozens of resume keywords) if we want to invest the time.

So I'm interested in how people make these choices. Could you elaborate?
> That kind of thinking is exactly why these sorts of communities become so closed to outsiders.

Which cause is first and which effect second?

Sometimes the leaders of these WANT to isolate and close off. This is a standard mechanism of psychological control.

However, things do change with time. I suspect most people in the US now regard polygamy as silly and stupid rather than an offense against society. Polygamy has been shown to have particularly bad destabilizing effects on a society overall; however, I suspect that a place like the US could actually weather polygamy now given that women have much more power and mobility.
But it's realistic. These days you don't get to eliminate your opponents. What you do is endless rat race on tiny margins.

Plug: "Epic Spell Wars of the Battle Wizards" are pretty awesome if you insist on elimination.
Plus Amazon Go eliminates the payment process. When you think how much time you lost by scanning every item and paying via cash or credit card. Amazon Go is much more easier and quicker.
I highly doubt so. The data privacy laws are pretty strict here.

Small point: in General Relativity you can have a vacuum solution of the Einstein Field Equations with arbitrary curvature; a test object can probe that curvature despite the absence of any (other) stress-energy.

A smaller point: "motion" and "tidal...effects" each implicitly chooses a splitting (in particular a 1+3 threading) of spacetime into space and time. That's fine; it's really hard for general relativity to confront observation without doing some splitting, and implicitly threading is standard behaviour (Synge does this in his textbook, for example, when discussing 3-velocity and spatial distance and offering up his world function biscalar; note that this is different from explicitly applying a 1+3 formalism).

Your central point is right though: coordinate transformations or arbitrary choices of splittings -- 1+3 threading or 3+1 slicings are examples -- cannot get rid of real curvature.
It really doesn't. The majority of commenters here understood my original meaning, and this entire thread about the definition of profit isn't even relevant to the point I was actually making.

Being so fickle about definitions that you miss the broader message, however, does make sensible discussion impossible.

We don't study philosophy simply based on who is first, we study texts because they are thorough and influential on future philosophical and political development. We know this because future scholars directly cite them.

Before all the aforementioned authors, it's all but certain that many of these thoughts were had by unknown people without the ability to archive them in depth. The Bible alone is evidence of this; for someone to write that denial of religion deserves death, they must consider religion as a choice in the first place.

This just feels like someone is shoehorning a narrative that they like.

There's no evidence that Amazon bought Whole Foods because it's an upmarket grocery store and avoided others. It's very likely that Amazon will eventually buy a "normal" grocery chain and serve as large of a population as possible.
Does this mean you use regular js and not es6?
While it might not have been a particularly "deep" interaction, I definitely got to know my favorite checkout person at Whole Foods, knowing what he used to do, keeping each other up to date on new things we were doing, and even following his move from being a checker at Whole Foods to being a manager at another nearby store.

> where there is even less real social interaction

Good?

I'm an introvert. I don't value random, superficial interactions with people I'll never talk to again. In fact, they cause me anxiety & I dislike them.

I do value the time with a select group of people.

And by reducing the time I spend in the supermarket it allows more of the human interaction I do value.

My social group has a wide assortment of views, from Muslim to Catholic to Athiest, to #TrumpTrain2020 to #NotMyPresident.

I've never witnessed nor heard of people having meaningful discussion with the checkout clerk. I've never seen nor heard of someone, after that brief interaction, saying "You know, you're right. I'll reconsider my position on the person of the opposing political party."

The statement marketplaces may have been true when we in the barter system, but it certainly hasn't been president in modern society for sometime. And I say that as someone who grew up in a town of 2,000 in the 70s and has lived in a large urban area for the last 20.
