"Trivially" might be overstating it. If you do the scan at 1000 dpi and get several people to check it was done properly then very probably you will never want to refer to the original again, because a scan is much easier to consult: just turning to a particular page is much faster, and you can zoom in without having to manipulate a physical magnifying glass. But I've worked with book scans done by ordinary people using ordinary equipment and I have on many occasions found that the scan wasn't quite good enough and I've taken the trouble to check with a paper copy whether a certain short word was printed in italics or whether the exact shape of the serif can help me disambiguate a letter which was badly printed in the original (the plate wasn't properly inked or whatever). I've never personally experienced a situation in which I've said to myself, "I wish I had another copy of this same edition to compare against", but I can imagine that might happen sometimes. So I think it is worth keeping multiple copies of the same edition, if it's an "important" book, or you have some reason for suspecting that it might be important: you don't know for sure what people in the future will be interested in.

Even the most pro free market economic theories have the core assumption that the free market only leads to efficient pricing under a set of core assumptions.

These include low barriers to entry, strong competition, perfect elasticity on both the consumer and producer side, and no mono/duo/oligopolies that prevent those from working correctly.

This is a classic oligopoly where the free market does in fact not work to find the "natural" price.
Those valuations didn't make any sense. Even Tesla's valuation still doesn't.

Tesla is still valued at 2x Toyota:

https://companiesmarketcap.com/automakers/largest-automakers...

and then at least 5-10x what companies that actually make a lot of cars are valued.

Tesla should probably be valued at something like #3 or #4, their market value needs to crater by at least 50%, more like 80%, to reflect their real long term standing.

Charge backs. Price matching. Product insurance. Consumer credit scores can go down, which reduces the maximum balance, which may be under the current balance, which may become a total loss of the account. There are plenty of risks for an _issuer_. Which are separate entities from the _network_.
It is a win friction-wise. I am pretty sure Visa/Mastercard have negligible costs when processing a transaction, and that 3% is what I guess they think is the upper boundary of what merchants are willing to pay before there's an incentive for a competitor with lower fees to appear.
Gyms aren't the solution. Gyms also make most of their money treating the problem. They are massively oversubscribed because they know most of their members don't actually go. Most of their members are on the "forever diet". You know, the one where you're always trying to "lose weight" but never actually do (usually the opposite).

The actual problems are things like food addiction and forced sedentary lifestyles. The solutions to these are things like taking food addiction seriously and treating junk food the way we treated cigarettes (ban all advertising for a start) and getting rid of cars in towns.
This must be the most unintuitive result of all of mathematics. Its very interesting what a seemingly simple axiom like the axiom of choice can lead to -- simple as in 'even a 9-year old can understand it', the consequences are rather enormous and not simple at all.
The natural monopoly emerges from the economy of scale: eventually you are offering a product at a price that nobody else can profitably undercut, because they do not have the same infrastructure that you do. And obtaining that infrastructure is too expensive for anyone to fund.

My credit union lets me open up sub accounts. I can set rules for the sub accounts. I can get a card that only draws from a sub account. This is all free.
The thing is though that `{ a: 1, d: undefined, }` and `{ a: 1, }` make a difference that shouldn't be there at all, and in this case its name is not very fitting as it does define an property of the object. This can be extremely annoying and the only way out is to always have tests around `null`, `undefined` and missing keys and have coding standards like I for one never use `undefined` explicitly; whenever it does occur it's likely a mistake; even functions without return value I make return `null` ("see, I have nothing to say here") explicitly instead of relying on the implicit `undefined`.

It's also increasingly common to pay without the credit card companies getting involved at all and have the payment completely free. At checkout you're just presented with a QR code which you scan from within your bank's phone app and which populates all of the payment details. Then you just tap pay and because the bank to bank payment is instant the checkout page will update within a few seconds and you're done. The downside is that this kind of payment is not insured and you cannot do charge backs (so smallish amounts only).
But it is a burden on the customer to use it. And in the US at least, you want to let people pay you as easy as possible, not have them jump through hoops like it is in the EU with a second factor authentication. Different approaches.

Do they?

What about? “The random variable X is a function mapping each outcome to the age of one of my cousins”?

Does that seem like a valid definition of the concept of random variable to you because the age of my cousins are numbers - just like probabilities mentioned by glitchc’s comment are numbers?
Let's do it one more time.

Correlation != Causation

Could the causation conceivably run the other direction? People with beginning dementia exercise less? Yes, that is quite conceivable actually.

Could there be a common cause explaining both? Yes, if you are in good health, with good genes, a good job, leisure time and money, then probably you are the type of person who'll live longer, sport more, and be cognitively healthy for a longer time. It doesn't mean the causality runs in the other direction.

In other words, this study shows what we all know. The 'good' people have all the good stuff. But what we want to know, will an intervention that causes people to exercise more do any good?

That's good because exercise wouldn't solve your problem anyway. You'd just be a fat guy who exercises.

Exercise isn't a misery when you aren't fat.

To lose weight you eat less. Unfortunately we've decided treating food addiction with pills and removing organs is the way to go rather than targeting the addictive stuff itself. Kinda like treating heroin addiction by removing arms.

Putting aside the fact that email is not free, if you think the complexity of a system that sends an email is comparable to the complexity of a system that processes real time payments, then you're kinda showing how little you understand payment systems (but I suspect this was just a flippant comment). Email doesn't require a globally consistent state to be maintained, it doesn't require cross-border settlement, there is no financial liability if an email is lost, it doesn't require a different set of KYC/AML/reporting regulations to be followed in every jurisdiction, or many other things that payment systems do.

> actual costs that exist

Money gets lost. Either really or because you've experienced shrinkage. Tellers are not perfectly accurate. Customers will try to scam you with fake money, if you notice, that's your loss. If you pass enough of it on, you will at least have to answer some questions. If coins are involved in your change you're going to have a bad time.

Retail in the 80s was not particularly fun. Running register tapes to look for missing money was an effective nightmare.

It's probably that credit cards have filled an effective void for so long we haven't developed cash handling and tracking technologies to the same level. We almost got there. Remember for a few years when almost all grocery stores had automated change dispensers?

We optimized for a particular solution and ignored the other.

I’ll hazard a guess: you never liked exercise, even as a kid?

If that’s the case, I’ll hazard another guess: you lived in an environment where you couldn’t just go out and play whenever you wanted?

I might be completely wrong in my guesses, and I apologize if I am. But I strongly believe that all kids are naturally predisposed for physical activity, and it’s the duty of the society to let them do that in an easy and safe way.
In 1986 "the book is more than just the text" is a sound justification for why a significant proportion of library stock can't "just" be digitised.

But we're long past that, we can digitise the images, paper texture, layout choices, almost everything if we choose. There are a handful of things we might justify keeping anyway, but on the whole the digitisation is just a marked improvement.
"Those grapes look really sour, don't they?"

Ask all the younger Greeks that had to leave their country and come over to Germany what they think about their Internet.

Ask how many of them have a home-based job in the UK, Denmark or Germany, but feel they can not go back simply because they don't have a minimally decent internet infrastructure to be doing fully remote work.

Ask a small hotel owner in one of the islands about their plan of turning their property into a "hacker house" in the off-season.

Of course, it's not the only thing that is lacking in Greece. But I can guarantee you that is one of the things that is holding it back.

We have many (about 1 per 20'000 people) short circuits consisting of exercise stations scattered about a forest with a jogging/walking path connecting them.

Introducing complexity is always something that needs to be introduced carefully. It makes things harder if you introduce it to early, but everything will break in a big bang if you introduce it too late.

Nowadays you can also start with a light weight MQ like Rabbit MQ and decouple your service just into a hand full components. This will set you up for scalability without introducing massive overheads.

In end it is also always a knowledge game. How experienced are you or how much time are you willing to invest into learning and understanding a technology.
Somewhat unrelated but is there any SOTA for what “vigorous cardiovascular exercise” should be to optimize benefits?

Should I just exercise flat out and try to sustain that as long as I can, or is there a level of vigorous exertion below flat out that leads to better results because of the longer duration?

> Exercise sucks.

Lots of people, including myself, love exercising. If nothing else, endorphins are a great natural "high". And I can tell that the rest of my system just works better when I'm working out regularly: I have fewer hunger attacks, I sleep better, I feel better. And, I just really like the feeling of picking up really heavy things (that being my current exercise of choice).

From what I can tell, the "exercise sucks" barriers most people face are 1) not everybody likes everything, and 2) it takes at least 2 months of training to get to the point where you can get the taste for the endorphins without being overly sore afterwards.

Now maybe you've spent 2 months trying all kinds of different activities (swimming, walking, hiking, weight lifting, cycling, wrestling, football) and none of them have worked, in which case fair enough. But if you haven't, I'd recommend trying it.

I can see why if you're overweight that running wouldn't be very fun. If you haven't tried weight lifting, definitely give that a go. If you're overweight, you've got a head start lifting heavy things (you), so it shouldn't be as hard to get into. People who've never lifted weights have this idea that it's mind-numbingly boring; but the mental focus you need to lift heavy things is actually a bit more like meditation. And being able to confidently lift really heavy things is an amazing feeling, not to mention having pumped-up muscles.
>the problems are lack of time for exercise and money for a healthy diet.

pretty much. You go to some circles that will keep swearing by "Calories in, Calories out", and blaming any detteral of this as laziness. It's basically the equivalent of saying "stop smoking" to a smoker. Yes, they are objectiely right, but also miss all the subtlety of the steps needed to "stop smoking".

Time is definitely the biggest factor, and modern society feels like it's demanding more time than ever of workers for less spending power than ever. Of course people don't have time to work on their diet/exercise when some are working 2+ jobs at barely above minimum wage.

This says nothing about ease of use. And for software development, ease of use matters. Otherwise we would all use assembler, or at most C++. They're very powerful and flexible.

Your proposed model for adoption doesn't "show up the elites", it destroys the ability of anyone who doesn't already have elite-level epistemic integrity checking skills to ground themselves in reality, and honestly may well over time subvert even decent epistemics via automation blindness. Using new tools is something that people should absolutely do, but using them stupidly for the sake of using them creates a small-to-modest momentary edge for an infinitessimal fraction of this especially reckless class of early adopters who luck out while most of them just serve as guinea pigs as the world figures out what the things are actually good for and irons out the rough edges. Regulating the way you ingest new information such that you can tell fact from fiction isn't "trivia recall", it's a way to retain a semblance of soundness of mind. It's readily apparent from the increasingly unhinged landscape of conspiracy theories that it is in fact not better to wildly guess at gaps in your knowledge if those guesses have a chance of becoming sticky, and human brains are a lot better at filling in gaps than unfilling them. You're not making a good case for not grounding usage of these tools in a realistic understanding of what they're good at - even setting aside the nominative determinism that's becoming increasingly apparent in your replies

I don't keep track of them, but if I try to think of any websites that I've visited e.g. since last month that are not in violation, only ~4 come to mind. And since I don't have any exact numbers, I have no choice but to give a conservative estimate.

because they forced their policies and standards onto the new startup company.

It's the classic mistake: you setup a separate 'startup style' company to move fast, but give them too much budget and too much rules, so they just spend the budget on rebuilding the same mess instead of innovation. It's a consultant heaven to make a lot of money, but in the end this really only works if the group company stays in the dark for a considerable amount of time and doesn't impose their ideas

Can someone explain this more simply?

If you cut up the sphere's surface into pieces, the combined surface area will remain the same. If you then reassemble them in a different configuration into two spheres both the same size as the original, the surface area will be twice as much.

I don't see how that could be true. What am I missing here?

ETA: thanks for all the explanations. The most succinct answer seems to be because it assumes the surface is made of infinitely many points, and infinity breaks math. 2*inf = inf.

One more reason why it makes no sense to treat infinity as a number.
