Engagement rings are very rare in France, I don't know personally any couple who did it and even the wikipedia page on it is very small, unless you are from the upper class or an international couple, it's pretty rare.
No. Assuming this specific paper's thesis, that is the conclusion. There exist other arguments not based on this specific paper's thesis.

Of those, I find plausible the observation that as we tame the world to suit us, we shrink. Cities, civilization, supermarkets, products, TV, internet. By this trend, we'll live in dream terranes before long. (BTW as people get richer, reproduction gets less).

But we'll need power, and eventually a dyson sphere to capture all the sun's light - perfect for an inward-looking, closed-off people! Then what, I'm not sure. Perhaps long before that, we won't need other suns; we'll have artificial suns (controlled fusion).

That's what happens to everyone else: as they grow in technological sophistication, they get better and better at directly meeting their own (previously evolved) needs.
Yup just ridiculous. Opting out of targeted advertising doesn't mean you can't show ads. Dumbest thing really, how much more money they were going to make if I consented to ad tracking? A percent of a cent?
The average engagement ring in France is 800$ (https://www.ladepeche.fr/article/2014/09/15/1952013-bagues-f...)

One comment above talked about $5600 for an engagement ring in average in the US.

That is quite a difference indeed!
There is no difference. This article might as well be about expensive handbags or colleges, but it so happens it's not. The underlying idea is to rethink what you spend your money (i.e. your time) on so that you get the most out of it for you.

For me the underlying principles boil down to two main ideas:

* Priorities. I personally value a great laptop over a great rug and a nice piano over a nice couch, so I will adjust my spending accordingly. This works within categories as well; I would value what the stone is/does materially over what the stone is/does culturally.

* Consider diminishing returns. When making a buying decision I look at what is available in the category and what the value for money curve looks like. A phone that costs 400 bucks is a significant upgrade over one that is 200, but adding another 200 won't bump the specs as much. This is not to say I'd never buy the more expensive stuff, but only if I prioritize it accordingly.

> “wouldn't a non-constructive proof would shed some light on the problem so that a constructive proof can be found?“

This is not necessarily true. Common examples where it doesn’t work that way usually involve proof by contradiction, like in the Brouwer Fixed Point Theorem. The steps of the proof only refute the non-existence of the fixed point, and don’t really offer any constructive insight into how the fixed point can be algorithmically located in general.

Other examples include many elementary calculus theorems, like the intermediate value theorem and Cantor’s diagonalizatiom theorem that the real numbers are uncountable. By extension you can think of the standard proof that the Halting Problem is undecideable as non-constructive.

In complexity theory there are also tricky non-constructive “almost proofs” that are used for intuition a lot.

One example is that it is believed that NP != co-NP. By “contradiction” you can show that if a problem was both NP-complete and also in co-NP, then NP == co-NP. Because of this, when theorists encounter a problem that is in both NP and co-NP, they treat this as “evidence” that the problem is not NP complete.

Overall, sometimes a non-constructive proof offers insight to think of a constructive proof. But often it does not provide any such information.

There is even the branch of logic called intuitionism, which uses the Principle of Explosion to effectively disallow proof by contradiction, which is related to the subset of mathematicians who will only treat fully constructive proofs as acceptable.
Ask HN: How are some startups able to offer life-time membership fees?
I've come across a few side projects as well as startups that offer users a pricing scheme which goes something like this: monthly, yearly or a one-off life-time membership fee.

By buying a life-time membership, a user is basically assuming that the company will stick around for a while. I appreciate that some users would get such a membership to support the maker.

But if the company were to fold within a few years, what's their liability?

I wouldn't say that engagement rings are upper class, but it's true it's only in certain groups. In my peer group, it's common, for example my brother bought one for his fiancée and my mom has one. But in all case they were gifted at the time of the engagement, not at the wedding.
OP here: lots of people have written about problems with Scrum (e.g. https://news.ycombinator.com/item?id=16892307 ). I'm trying to take a bit more of a systematic, longer, researched and justified view of things, so any feedback is very welcome!

>it's unethical to create new life and choose to go extinct.

I don't get this. What use are ethics when everyones dead and gone?
A couple of years back my wife (of 27 years) bought a ring for herself with a conspicuous "diamond" on it - I think it cost about £30. Anyone who noticed thought it must have cost tens of thousands and how generous I was.... even though it was fake and she bought it for herself on a whim!
One difference is that nobody thinks that they should invest vast amounts of money in handbags, with the explicit promise that handbags are eternal and an implied promise that you will be able to convert it back to money at a trade in of roughly 1 to 1, if you need to.

It's Deep Blue, not Big Blue. The parameters used by its evaluation function were tuned by the system on games played by human masters.

Besides the technical details between vgo and dep. The go team just announced and accepted its own proposal, completely ignoring the community's solutions, dep was even called the official experiment, which is sad.
Yeah big time. But you can say that about a lot of things. Point I'm making is that if people want to consume ridiculous things the current system we live under kind of favours that. If it isn't diamonds then it's going to be some other crap that requires other people to live lives of utter drudgery. That's kind of the point. If you want a vision of the future, Winston, imagine a Jimmy Choo stamping on a human face forever.
>What is the difference between a diamond and an expensive handbag or other accessory?

Usually there's way less war, slave and child labor involved in the making of a handbag.

It's not so much as worrying about their personal (gang, group, person) reputation, but rather the reputation of kidnappers in general.

Kidnapping is a business. I would assume people who kidnap others do it more than once. If you want your industry (kidnapping) to continue to exist/be profitable, then would-be-payers must know that they are likely going to get the person(s) back.
De Beers have spent most of a century convincing people that a large diamond is a mandatory part of an engagement proposal. You mightn't be affected by this propaganda campaign, but a lot of people are.

Lots of other luxury goods are bullshit, but none of them are marketed as an essential part of a normal life. Nobody feels under pressure to buy a Louis Vuitton handbag or a Rolex watch just to get engaged. De Beers have effectively re-invented the dowry, with the significant difference that unlike diamonds, cattle or gold keep their resale value.
Most package managers ignore the lock files of the dependencies when picking up versions - they only use the lockfile of the topmost project for picking up versions.

The big difference with the MVS strategy in vgo is that the dependency list of a dependency is actually used to determine the version. If package A uses B, which was tested with v1.2 of package C, you will get v1.2 of C, even if there is a later version of C available.

In the typical package manager scenario, the dependency list of B may be pointing to an old version of C which does not even work with B - there is generally no way to ask : give me the latest version of C which was tested with B.
The old rethoric. Not, this is not the japanese government, is a company, one of several, and the goal of private companies is to maximize the benefits, not to care for the environment. For example killing pregnant animals (Something that is normally forbiden in the laws that regulate hunting in most countries).

Of course all affects the environment.
Interesting idea, but seems like it might have some latent flaws. Even regular football needed a century of rule-tweaking to keep it relevant, would be a marvel if something as tactically complex as this could spring into life fully formed.

Another thing I've wondered about - regular two team football, but with more than one ball ('MULTIBALLLL!')
Would be hard to follow, but an intriguing idea.

Uncontacted tribes in the Amazon likely wonder the same thing. It's such a big Earth, yet only a few hundred humans are known to exist.

Why are there no other detectable signs of human life, like smoke signals, territory markers, or emissaries from any more but a handful of other tribes? Surely if advanced humans existed, they would have contacted these tribes by now, to share technology, discoveries, and medicine. Yet they haven't.

How can the whole planet be so... silent?

7 Tips to Grow a Startup Without Breaking the Bank
Well it's like vegans. Except here instead of animal suffering, it's human suffering; which can give a greater sense of importance to the cause. And in turn, it would make people against diamonds feels justified to be more aggressive.
Only after the dot-com bust killed off all the weaklings ... there was a brief "cold-snap" after 2001 ... then Web 2.0 happened.

The most optimistic opinions on where we would see autonomous car were on the 2020s.
Instead we have autonomous car hauling people on the streets without any safety driver since 2017. And if everything goes accordingly their plan they will launch a commercial service by the end of the year in several US cities.
To me it seems a resounding success, not a failure.

From the "Special CAT II and CAT III operations" you linked:

Some commercial aircraft are equipped with automatic landing systems that allow the aircraft to land without transitioning from instruments to visual conditions for a normal landing. Such autoland operations require specialized equipment, procedures and training, and involve the aircraft, airport, and the crew. Autoland is the only way some major airports such as Paris–Charles de Gaulle Airport remain operational every day of the year. Some modern aircraft are equipped with Enhanced flight vision systems based on infrared sensors, that provide a day-like visual environment and allow operations in conditions and at airports that would otherwise not be suitable for a landing. Commercial aircraft also frequently use such equipment for takeoffs when takeoff minima are not met.
Yes it is normal in fact for whales. English speakers use calf for the young, cow for female, and bull for males. https://en.m.wikipedia.org/wiki/List_of_animal_names

How is it hard to dismiss the moral advice of people who lack integrity?

Because it's "probably" in your opinion that they sacrificed integrity, it "seems" like that's not just probable, but fact? Nonsense, even before getting into how you just equate any lack of integrity with any other, as if it was binary, instead of a matter of degree.

The default for unintelligent life is to survive at all cost and fill every niche. You're suggesting that intelligence flips that purpose so that every sentient species eventually becomes depressed suicidal existentialists?
Diamonds have pretty effectively been marketed across the class spectrum as something you have to buy to get engaged, to the point of the "two month (salary) rule" being a thing. Other luxury goods don't have that.
The BBC recently requested information about the use of facial recognition from UK police forces. Those that use facial recognition reported false positive rates of >95%. That led some to abandon the systems, others just use it as one form of pre-screening. Mass surveillance with facial recognition is nowhere near levels where it can be used unsupervised. And that's even before people actively try to deceive it.

For advertising, I'm also not sure if there's been a lot of progress. Maybe it's because I opted out too much but I have the feeling that ad targeting hasn't become more intelligent, rather the opposite. It's been a long time that I've been surprised at the accuracy of a model tracking me. Sure, targeted ads for political purposes can work very well but are nothing new and don't need any deep learning nor any other "new" technologies.

Where I really see progress is data visualisation. Often dismissed it can be surprisingly hard to get right and tools around that (esp for enterprise use) have developed a lot over recent years. And that's what companies need. No one's looking for a black-box algorithm to replace marketing, they just want to make some sense of their data and understand what's going on.
Of course AirPlay and AirPlay 2 support this, if the application sending audio supports it.

Both anodizing and oxidation of aluminum look different from polished steel. Notably, oxidized aluminium loses its shine. Moreover, anodization can get scratched after which you get the ugly oxidized aluminium.

The other opposite would be considering your final day the "most important day of your life".
The insurers have been paid in advance. They pay the ransom from their coffers, so are incentivised to reduce the cost as well as keep customers (not fuck to the recovery).
I can't believe I'm about to defend a marketing slogan. "Most important" doesn't imply "best", in my opinion, I think it implies that this day has the most impact on your life, so make it a good one. Maybe future days will be better because of what happened on this day.
That would be a marketing battle, which is often won by the side with the biggest marketing budget, probably the well established natural diamond industry.

Besides, I personally feel that "lab grown diamonds" have more weak (marketing) points than "natural, made by stars, millennial diamonds". Could be wrong though.

Australia just got PayId this year which means you can send any amount of money to anybody who signs up via their banks and receive money in seconds.

Artificial scarcity in watches

https://www.theguardian.com/business/2018/may/18/richemont-d...
> I would make the suggestion that their scarcity is entirely artificial to inflate prices.

You're suggesting people pay $4,000 for a LV bag because LV is limiting their supply and they're difficult to find? I don't think that's the case. They're expensive because only LV can produce bags with their logo, and they're charging as much as people are willing to pay.

Artificial scarcity might be the case for a special edition bag, or a Nike or Adidas shoe produced in a unique color with a limited run of 100 products. But, that's not the core of their business or the source of their overall higher prices.

In short, LV bags are simply not scarce.
A nice engagement ring does not require a diamond though. It does not require 3 months of salary.

So what _is_ the point of an engagement ring? To show love? I can do that without a ring. To show I'm taken? I've got another ring for that. We both do.

Those rings cost about 20$ together
Do not attribute to malice that what is adequately explained by stupidity.
But current signs designed for humans work well. They're machine readable (traffic sign detection is available from basically all manufacturers) and can (usually) be understood without prior knowledge and don't need much change over decades. I think there are few examples where messages were designed for computers but are easy to understand independent of the system, manufacturer. ASCII encoded text files are the only thing that come to mind.

I think that agrees with my "industrial grade" comment. :-) In production we are currently deploying boxes with 256GB of RAM. But for our backup server, it's hard to spend more on RAM than on the disks in it. The box is capable of it, it's just the cost that makes it unappealing for this use.

For various reasons, the backup server doesn't get much priority.
A Salute to All Dads on Father’s Day
Seconded. Unlike Node/Ruby/most other modern languages, Go devs actively avoid including dependencies if at all possible.

And contrary to rumour, this is not because Go's dependency management sucks. It's more about the pursuit of simplicity, and avoidance of magic.

You can write pretty much anything using just the standard library (and some of the official packages, like the crypto ones). As the parent said, it's good practice to go as far as possible with just the stdlib.

It works for general purpose videos. Transcripts of any kind appear to stop working whenever there's domain knowledge involved. That doesn't matter for most youtube videos but is crucial if you want to have a multi purpose translator/encoder.
That's cool. It's also cool to give a token (such as an engagement ring) or exchange gifts as part of the engagement as well.

Why criticize the way other people choose to celebrate their engagement?
Unfortunately this is one of those American traditions we love to hate but are for the moment powerless to change. Your significant other may not care but societal pressure and expectation is hard to get around. She has a mother, sisters, friends etc. It is the same reason an expensive handbag makes absolutely no sense to a man but matters so much to a woman. It is confounding.
You're not kidding! My wife was a wedding coordinator for nearly a decade and I used to joke with her "What next, wedding water?" Then someone got the bright idea to buy bottled water wholesale, label it with the wedding details and sell the result at a huge markup.

Ask HN: I want to write the most idiomatic modern ReactJS, where can I find how?
I'm an experienced ReactJS developer, but I want to take my coding to the next level - I want to ensure that I'm writing code that reflects the current state of the art thinking in how to write ReactJS code.

So I'd like to ideally find a summary of how to do that.

I know the information is everywhere, but it's scattered all over the Internet, and how do I know if what I am looking at really is the most current thinking in writing simple, organised and powerful ReactJS code?

So my question - is there some place that gathers together a collection of the most up to date thinking (with examples) of how to write well organised, simple ReactJS? Presumably either written by some recognised leading authority on ReactJS, or with some other qualification to prove that the author really is in tune with the most current ideas and recommendations?
