All else equal, I'm more likely to find out about a dumb gotcha in a commonly used standard before it bites me than I am in my own sui generis design that nobody else uses. You're right that crypto of any sort requires care in how we use it, but preferring a more widely used method lets us leverage the care of others as well as our own. And if we don't bother, we're probably about as hosed either way.

And, yeah, if it's practical to just generate and issue a secret from the server side and authenticate it at a single point when the client presents it back to us, we may as well do that. I'm not sure how practicable an option that is in OP's case, though; the description of the problem suggests there's something rather strange going on, and I don't grasp it well enough to speak to what scheme is really most useful in the context. But it does sound like having the client bear its own claims is useful, and JWT would be the obvious go-to for the use case.
Once it hits the economic repressed areas, where the majority of folks don't have debit cards or bank accounts this will run into an issue.

There is a very large and growing set of folks in this nation who use cash and barter only.
The Coinomi wallet for Android seems to be early in supporting these forks. When it came to claiming bitcoin gold recently, running it in an android emulator and typing in old private keys was still the most reasonable option for someone with only iOS and macOS devices available.

If you had your BTC in a hardware wallet like Trezor during the split, claiming BCH and BTG was automatic with firmware upgrades which only came with considerable delay. Claiming lessor and unsupported forks off a hardware wallet seems like a major chore and security risk since you’d need to regenerate your private keys off-device.
This is really, really nice from what I could tell from the video. I could see this being very useful!
England was barely affected by the first World War. France, Germany, Austria, Serbia, the Ottoman Empire, and Russia bore the brunt of the fighting.

And compared to the other belligerents, it was barely affected by the second, too. British colonial policies during the war killed more of their own subjects in India, then the Germans ever did on the home isles. (For anyone wondering why India sought independence... Well, that was a factor.)
An alternative ambulance service wouldn't be just an 'app', but an actual entrerprise with various logistical, legal and medical operations and probably hundreds of employees.

The US would be a better place with that hypothetical startup.

If Obama couldn't successfully reform healthcare long-term (as Trump will repeal it sooner or later), what can regular people do?

Let them make that app.
Einstein (relativity, nuclear), Heisenberg (uncertainty principle), Obama (for his color).

I would place Bezos before Musk, because Musk risks too much and is not really that successful. But even Bezos will be forgotten. Who remembers the founder of the richest and then most important company of the world for centuries, the Dutch East India Company (VOC)? Johan van Oldenbarnevelt? The worlds first bond and stocks sensation. Any rubber baron? None.
Only those who wrote about them became famous. Literature.
The HN platform deliberately discards characters beyond IIRC 0xFF - it's been a while since I looked at the source, I'm probably wrong about where it cuts off. An odd design choice, but a design choice all the same - it doesn't bear on anything else in any way I can see.
I've spent some time recently about what the world would look like without advertising at all (or very limited types). Is that a thing that has a name?
Don't try to replace a good dictionary. In other words, don't fill your writing with definitions.
> How many times have you done business at a place that is cash only where you bought more than a few items?

Literally every time, but I don't live in the US.

> Having a count thar does not come out cleanly at the end of the day is a major inconvenience depending on the business.

Then round up at the end of the sum.
>They're heavy, they take too long to count, and they have no buying power.

Depends on the currency. In Europe--both pounds and Euros--coins are pretty significant. Of the currencies I use, it's mostly the US where change is often a small denomination annoyance because, for whatever reason, we collectively decided some time around 1950 that we were never again going to change either the paper money or coin denominations in wide use.
If you’re going to ask what someone _will_ do, it’s best to keep it to a simple binary decision and always remember that that’s only representative of a single moment in time/the current customer service cycle for that individual.

As this article identifies correctly, the more important question is the harder-to-quantify “why?”.

Armed with this, the fluctuating and heavily biased score will have more meaning and context. Using that data to improve the service/product for the next cycle may do more to realistically reflect sentiment change than any weirdly random maths.

Of course, this still ignores what someone actually does do. But it’s possible to track certain cases of referral and actually to encourage trackable referrals using the correct approach. This is a more solid measure (if possible) than any hypothetical gauge of future behaviour - again as the article points out.
I think this means that 1 in 5 pages hosting a third party ad network has no relevant content for a legitimate web user, so visits to that site must be by bots. Not saying that is what happens, just a way of interpreting it in a way that is not impossible...
Actually I forgot the perhaps most crucial point. Very few people are in unions who work as software developers. So it doesn't really make logical sense to make conclusions about software developer salaries based on unionization rate in the rest of the country.

Engineers and software developers are if anything members of what could be more called trade groups. These groups don't negotiate or push for salaries on behalf of members, nor do they do things like organize strikes.

To test you hypothesis I think you have to look at several countries in Europe at similar GDP number and compare salaries. Then you'd have to compare between those of different GDP numbers and see whether GDP or unionization rate correlates most with salaries.

I got to point out however that such a task is momentously difficult, because differences in how things are recorded and rated. As an example I just remembered several other factors in addition to the previous mention that I forgot.

1) The salary quoted in Norway, is the money workers get after special income tax is deducted by the employer. This is about 14%. So a 65k salary is more like 75k if you consider this tax.

2) High living expenses in Norway is heavily influenced by a very high VAT tax of 25%.

Sure that doesn't mean the money is suddenly in your pocket but it means it doesn't just disappear. It goes to cover extensive welfare services, which e.g. Americans would have to pay for out of pocket.

In essence it is hard to compare very high tax regimes with extensive welfare benefits to one with low taxes and few benefits.
The recommendation engine seems to be mostly about pushing their original content. Not shocking there.
Most words have multiple definitions, hence legal definitions.
After living in Germany, I can't go anywhere without cash. It's like walking out the door without my keys.
Is that legal in US? Poland for example has a law saying that cash must be accepted, refusing cash payments results in immediate fine of about $135
Now you've got me interested, look harder! (:

I normaly push the back or close tab button when greeted by a welcome ad.
What would be the Google’s business model then? If display ads go, their money well dries as well.
> “I’m really not worried about whether advertising will be able to find its way through digital channels. I am concerned — very, very concerned — that costs of ads will go up and up and up from this unethical obstruction”.

The moment I read this a huge banner obscuring 80% of the page popped up inviting me to "join banner ad network" or somesuch.

I couldn't care less about "unethical obstruction" by AdBlock as long as advertisers feel that they can freely obstruct me.
In the US, cash must be accepted as payment for (edit: public) debt. However, there is no requirement that all transactions must accept all legal tender. A business owner can refuse to enter into a commercial relationship with you on the basis of your method of payment.

I have clicked ads for Airtable, Tile, Clarfai and Amazon Products.

I have bought Tile, and Amazon Products and I have used Clarfai in projects.

If the ads are that useful I will click them.
Healthcare in the US sounds nightmarish. I'm a UK citizen and broke my leg badly in France; ambulance etc. Whole thing was <75 GBP. That was for the cost of crutches and medicine in France, X-ray+ER visit was free. Then after I got my train back to the UK I had complex reconstructive surgery for free on the NHS.
I think that's because an acknowledgement that the kind of marriage one selects has an "environmental impact" immediately brings the sacred cow of gay marriage into question.

When it really shouldn't. You still have a fundamental right to select the type of relationship that's right for you, but you do have a responsibility to be mindful of its effect on society. This doesn't just mean ban stuff. Perhaps for polygyny, that would translate into making the relationship non-exclusive, rather than choosing against it altogether.

I understand that healthcare is more expensive than food for all those reasons. What I don't understand is why there can't be a market for it. Expensive services can have markets too.
We used a cryptocurrency miner as a heater this winter and it really worked
Surfing through the web back in October, I stumbled upon an odd but genuinely fascinating contraption: a Russian cryptocurrency miner that leverages the heat it generates from stacking Ethereum to keep your room warm.

Shortly after I wrote about this unusual device, Comino – the Russian-based startup behind this invention – reached out to us and kindly offered to ship one of its miners for us to test this winter. We gladly took them up on their offer, and a couple of weeks later, the Comino was already installed at our cozy office in Amsterdam.

More on the story:

Got point. I think the concept even applies to 1st world countries, where in cities like NYC lower income people will endure decrepit conditions for similar opportunities.

There's also this notion that even if you're in poverty you can disguise it living in the city and bring part of it.
And some people think that downloading copyrighted content is the same as stealing a loaf of bread.

>It has come to the point where I consider a product dubious, if it appears in online ads - the exact contrary from what ads try to achieve.

The industry is pretending that they did not notice that trend, but that will come to bite them sooner or later.

The longer they delay the U turn, the less reversible this idea gets in minds of Internet users
Don't be so harsh on yourself. Frankly I too am sometimes one of those idiots. The urge to advice someone, especially if you think you know the domain well, is very hard to resist. While I always was annoyed by advices (THB also when I needed them the most), it's rather late when I realised how much I was guilty of giving them invasively. Since then I'm actively avoiding giving advices unless asked.
This is the thing, the laws in the USA and UK already have provisions for death threats, so when you have to fall back on hate speech or hate crime it is not clear at all that 'hate' isn't merely an appellation that denotes 'people we don't like'.

We talk of dog whistles, but the phrases hate speech and hate crime are also some kind of whistle. If there is a crime, then there exists a law to deal with it. What then does the 'hate' add? Subjectivity and political bias in my opinion.

When I see my ideological enemy I don't get good feelings about them either, but they have the privilege of being able to talk, that should be what is right.

I'm not sure how Google is handling these case now, but I guess you may receive a cease and desist letter and an offer to buy the domain for a few hundred/thousand buck in a friendly way.

Author is arguing it doesn't work. You're begging the question.
Combining cash and card payments gives you the worst of all of them. Buying things takes even longer (giving them cash, them counting it, calculating your change, giving them your payment system card or whatever, them applying your change to that) and you still have all the privacy concerns in the paper trail of what places have been issuing you change and when.
> every time a rich man takes an extra wife, another poor man must remain single

Or he could simply be already dead from all the warfare. These two things connect in positive feedback loop: men dying in war create gender misbalance that would push more women to become second and third wives as well.
> No way to batch the transactions, because they need to be online to validate the card. While you could potentially batch card-stripe data for later use, (1) you shouldn't even build that capability into your POS system because it would be a major hacking vector

Is this your opinion as an end user thinking about the system from first principles, or the actual consensus of the industry about how things actually work?

A quick Google for 'offline credit card transaction' brings up a huge number of links to POS vendors explaining how to do exactly this, as far as I can tell. Is it referring to something different?
Online advertising is confusing to me. Clickthrough seems like a very limited view of what advertising actually is or should be. I don't know how much advertising money is being spent overall these days but for most of my life, advertisers and their customers have done just fine using billboards, TV ads, newspaper and magazine ads, and other situational impression-based advertising. Billions of dollars were spent and made on such ads. The prices were based on estimated impressions, not on how many customers immediately entered into a business transaction before doing anything else. It's ridiculous to expect website users to drop what they're doing and click through to some other site that they know is going to try to sell them something. It's far better to get your brand and product in their minds via the impression. It's far more likely this will pay off in the long run. Asking users to engage immediately is asking them to throw away what they were doing for something they weren't. That's foolish. I wouldn't be surprised in 90% of the "clickthroughs" are mistakes anyway. That would explain why phone clickthroughs are so much higher, because it's way easier to accidentally click on the ad instead of the X.

I also wonder how the listed stats on how well people remember the last banner ad they saw compares to magazine, newspaper, and TV ads. And how the numbers change with different layouts and approaches. I'm sure there are people in the industry who have numbers on this, and they must not show what I think they show. But the direction web advertising is going is not a healthy direction for anyone involved. I feel like a major change in the CW around the current approach to online ads has to happen.

Ad blockers would be easily thwarted if publishers hosted the ad content themselves. There's obviously a question of potential impression-count fraud to be addressed, but magazines and newspapers and TV and radio broadcasters have all solved their own versions of these problems. But it's not like the current system of ad networks that are filled with literal scams and thousands or millions of fake websites serving fake ads to fake clients via fake web searches are exactly fraud-free. I think the software engineers who've created the current broken system did too good a job of selling their cleverness, and we've got a bunch of wrongheaded metrics and approaches that are feeding a vicious cycle. How do we break out? I have no idea. But the answer has to come from the publishers and the companies looking to advertise. Podcasting seems to have found a far healthier balance. And maybe we're just in the golden age and the money ultimately won't be there in the long run, but regardless, the web is long past its own golden age.
There’s also an expectation that women will marry ‘up’, even in first world countries, I think. It’s very ironic that women who develop themselves have a smaller option pool of mates.
Most of China's city's the man who decides, don't know city develop, the purpose of what they do is simple, to please their superior, for their own career, or what they do is just what they like.

Qui prodest?

It is quite apparent why CC companies offer $10k in rewards: they will keep commissions on all transactions.

Anecdote: recently I bought a used car. Initially we agreed on bank transaction, tried several banks, some have low limits so low it would take months to move money. Others wanted transaction fee as high as $200 on 20k transaction.

Gov wants to get rid of cash because of surveillance. Banks and CC companies want to be gatekeepers and tell you what you can and can not do with your money. And to pocket as much fees as possible...
> it literally pins the blame for everything bad that non-white people do on the one thing white people ... have criticized others for for two millennia

While I don't think that polygamy is the root of all evil, it is a fact that "white people" countries don't have these bad things happening. Wouldn't it be logical to suggest that some difference in behaviour might be the reason for it?
The supply of labor is more like an infrastructural problem for capitalism, it's already a truly known and artificially influenced thing. In fact, with less concentration more people are going to be pushed to become surgeons, not less.
I've experienced something similar at resturants in TO recently! Not only didn't they straight up refuse cash, they asked me download their app to pay for food.

Obviously I walked out and got lunch elsewhere, but later when I was told that they sell their own currency in the app for CAD in denominations of 5. But their food + tax, is never sold at that amount - meaning, if your lunch is $10, tax makes it $11.3, you have to pay $15 in the app. If you have no intention of coming back, you loose the rest. This is such a scam.

Also what's the problem with accepting cash? It's trackless and it's anonymous - I love it. Why should everything I buy be tracked by Banks, Corps and everyone in-between? Furthermore, unlike credit, there's are no fees associated with it so it's slightly better for the seller too.

Btw if this does not give you a worry, think about this: all your expenses always end up at companies like Equifax. If them already selling it does not scare you, a leak should. Imagine if your transaction history can be used to refuse employment, housing etc. (without letting you know that's the case). Cash does not have any of those issues.

The biggest 2 main issues with cash is - what if I get pickpocketed? and the solution is to never really walk around with more than $50-100. I've been using cash since I was a kid, and I've never gotten pickpocketed. The 2nd one is tracking your expenses - but I personally feel like using cash has made me spend a lot less than when I used my credit card.
They seem to require an address. How do I give money to a homeless person to use at one of these stores?

Can I buy a handful of Blue Dot cards at the drugstore, load them up with about $5 or $10, and hand them out?
How dare you be the one to assert what is fruit and what is poison?
When I go to Mexico its mostly cash dealings. The cashiers work much faster than the credit card machines and people act a bit put off if you pull out a credit card.

It is interesting to see the difference from the US to Mexico.
I don't have a comment on the content of the article itself, though it will be interesting to see how the competing standards shake out in the longterm.

I did want to say that while I read through the article I was struck by how high quality the writing was. I'm so used to technical writing being relatively low-effort blog posts. This level of detail was a real breath of fresh air.
> You'll be hard-pressed to find the sort of systematic racism found in the US (especially by institutions) anywhere in Europe

This ia really common misconception perpetuated by (white) Europeans. It couldn't be more wrong.

Systemic racism is pervasive throughout Europe, and in many ways, it's even more institutionalized in Europe than it is in the US.

Please stop spreading the myth that Europe is free of institutionalized racism, or even that it's somehow better in this regard than the US.

(ach!), ICA automatically obey the second principle
of thermodynamics and, more generally, display
a full-featured statistical mechanics analogous
to that of Hamiltonian systems. As additional
structure is introduced (for instance, particle
conservation), macroscopic mechanical features
such as elasticity, inertia, etc. naturally
emerge out of statistics itself. In sum, once we
make sure that it is conserved, information has an
irresistible tendency to take on a strikingly tangible
aspect (cf. [73]) to materialize itself.
