> Most people date/marry someones equally attractive, from an equal class, with equal education.

Historically, the second has been strongly true, the first much less so, and the last basically false, though somewhat less untrue if you read “equal” as “in a roughly similar point on the distribution for their gender”.

> And of course there are many cultures around the world with arranged marriages, and those almost always specifically aim to match equals from the same class background (or higher).

If someone is getting higher, the other partner is getting lower. There is a necessary symmetry there.
Almost anyone at a hospital or university setting is on salary.

Private practice can be another story, and perhaps there your argument would be more compelling. But many physicians, surgeons, specialist go into private practice to get out of bureaucracy, or, increasingly nowadays with providers who do not take insurance, to avoid the endless paperwork and hassling of insurance.

Most people get into medicine for the right reasons; to help other people.
Or stop eating meat. Probably a better choice.
I have two issues with this article.

First, aren’t people going to be looking to pair up with someone in the same socioeconomic class anyway? That’s what we’ve mostly been doing over the course of history. That an app is based on this is not surprising. And I have a hard time believe apps perpetuate what we are already doing or exacerbate it.

The second is the graph in the middle regarding distance from city center and population with a degree. Haven’t we, in general, been getting more degrees since the points of comparison? How is this, again not already distributed according to pre-existing trends? The curve also does not change significantly besides being shifted up (corresponding a generally high rate of university degrees). Is there a actually significant shift happening with those without college degrees with regard to distance from city center? I think not, or they would have showed it and it would have been more convincing.
Bitcoin is entirely arbitrary. Given that the concept of cryptocurrency (as a get-rich-quick scheme) has been proven, there's nothing stopping people from creating another one. And then another, and another, and another. The problem really is with the whole concept of cryptocurrencies.

My wife and I met on OKCupid, although that was seven years ago. It was a fine platform then, for finding non-monetary compatibility.
That's a strange psychology that I can observe in myself.
And yet, I bet there's at least a few dozen people in the world that would fall in love with such a thing, and get viciously angry if you tried to mess with their workflow.
Actually, it has been claimed that online dating has made marriages more diverse:

So perhaps the effect of this will be a return (total or partial) to how things always were.
attrs does a pretty good job, while also supporting older Python versions: http://www.attrs.org/en/stable/
>If we date someone from a different economic class then one party is prone to abuse that power imbalance and take advantage...

Yep, been there, done that. It isn't even always intentional, it's just that when someone from a very different economic background, and who has a very different approach to handling finances, marries someone who has high earning potential, I've found they just can't reconcile these very different viewpoints.
I absolutely do not find this the case in Tinder (or other obviously less 'filtered' and more niche platforms)
On a societal level, yes it's bad when romance stratifies along classist lines, not only because people miss out on potential compatible partners, but also because it increases inequality and cements generational wealth/prestige.

On an individual level, it's definitely a good idea if you're wealthy. Since so many things correlate so well with wealth, or have wealth as a prerequisite, it could highly reduce someone's signal-noise ratio if they're looking for someone with those traits. For example, if you're an entrepreneur, or an amateur tennis player, or someone trying to play the corporate ladder climbing game like the example in the article, and you want to find someone similar, you'll have much more success finding someone similar to you among wealthy people, even though wealth is not necessarily a prerequisite to any of those things.
I believe they acquired the rights to 'Java' and they're arguing that gives them the rights to 'JavaScript'.

Which is fair-ish -- it should have never been named Javascript to begin with.
The app can increase the degree to which the existing norms are realized rather than aspirational; to the extent that individual acheivement of the goals of the existing norm has adverse social consequences, that is rightfully a source of concern even if it involves nothing personally blameworthy and no change of norms.
Historically, men date down (professionals marrying their executive admins, nurses marrying doctors) whereas women will not, so this percentage is based on how many college eduated women can find equally or greater educated, eligible men. Citation below.

Well, I'm still struggling with the question!

I wasn't thinking ideas vs their expression.

I see you're saying: you can have different expressions of Euclid for people of different abilities. (Actually, even different proofs for different levels: the high school proof of the Inscribed Angle Theorem is different in part from Euclid's, III, 20 (though I found Euclid's clearer and simpler)).

The difference I noted was just that geometry is like one codebase. But programmers deal with many codebases - there's no ugrad or high school course in a particular codebase!

Though, in a large company, do you get experts in their key codebase, both practiced and talented.
But there's still a reluctance to invest your all in a codebase - what if they rewrite? Or go out of business? Or you quit? Your investment is lost. Not so with geometry.

There's also market forces for the adoption of third-party libraries (a library of theorems - like Elements' books!) - dominating the market will require being accessible to a range of abilities. A "pop culture", for better or worse.

I guess you'd say: "fine, the easier expressions will dominate". But I don't think there'll be any higher expression at all...

So... not a difference in essence, just in its role in the world.

BTW I find Euclid very hard to read, but easy to understand (so far, anyway).

BTW those links I gave are to a "wiki-like computer document".
I'm dreaming of seeing a wasm DOM api that directly binds to the browser's apis, without passing through javascript.

Is this even a possibility?
That is actually what I had to justify the first time (about 4 years ago), which was the more difficult one. We had a giant spreadsheet in Google Sheets with all of our logins and everyone seemed okay with it. Convincing them it was insecure and needed to be moved to Keepass was a nightmare. This took a good half year to do.

The second time (about 3 years ago), I had to convince them that team management and selective sharing were necessary and that we should upgrade to a paid software. This took several months to get approval on, even though it's only like $400 a year for us; thankfully management seems to agree that it is worth the costs now.

To be fair, I don't consider myself very persuasive so it's entirely possible that I just did a really poor job of it.
No it is not, or I’m too ignorant to find it. Where are the PCB design files?
yes I do! I have noticed the sleep == disconnect thing. I'll look into it, thanks.
There is a little asterisk under the chart that clarifies that they are talking specifically about FOUR-YEAR DEGREES. That makes much more sense.

There are a lot of people attending community colleges or getting their associate’s degrees.

Otherwise I’d be pretty shocked if it was all degrees. 15% is way too low for that....at least I’d think.
Online dating is just 90% random chance that both parties will be compatible, which is why quick swipe apps are so popular now (and what OKC has recently transitioned to as well). It allows for a greater throughput of matches, so you can eventually boil it down faster.

I think the more detailed profile of OKC has always been very helpful conversationally, but really that's about it. I think the greater fraction of successful OKC dates is simply a result of it being around longer.
> Funnily enough I met my current partner on OkCupid, which seems like antiquated by modern dating app standards.

There's a bit of demographic selection here (people who are likely to use OkCupid may be more of your type), but OkCupid's whole proposition, early on, was gathering a boatload of information about you, via personality tests and data experiments, and hopefully presenting people who are at least likely to keep a conversation going.

As teirce points out, the see picture, swipe dynamic of mobile-native apps is more conducive to casual encounters. It certainly puts more weight on physical appearance and status signals.

OkCupid used to publish detailed posts about their experiments, but I can't recall what ratio they found of "people who are contacted frequently" to "people who mostly initiate contact", but I'd hazard a guess that it's much higher on Tinder. Such an app tends to be winner-takes-all, with a long tail of people who are mostly ignored.
The really funny part is that SA demonstrated that it is also the case is arrangement - pretty much no one cares about the bottom 80% and people pay a boatload of money for early access to the top 5%.
'Distorting' is an interesting choice of a word for a factually incorrect statement.

I'd recommend against starting with "Against Method".
Instead, go directly for the 'sequel' both to Feyerabend's "Against Method" and to two paper/essay collections (both published in 1976, two years after his death) that essentially originated from Lakatos, although they contain numerous contributions, among others by Feyerabend, "Method and Appraisal in the Physical Sciences: The Critical Background to Modern Science 1800–1905" (edited Colin Howson) and "Method and Appraisal in Economics" (edited by Spiro J. Latsis), namely, "For and Against Method: Including Lakatos's Lectures on Scientific Method and the Lakatos-Feyerabend Correspondence" 'by' both Imre Lakatos AND Paul Feyerabend, which Matteo Motterlini painstakingly assembled from the drafts for the book (which Lakatos and Feyerabend both wanted to produce, but which never produced a finished result in their lifetimes, primarily due to Lakatos' unexpected death in 1974.)

I say this because of what I personally like to think of as 'paraduality' in science which both Lakatos and Feyerabend discuss & address, but from 'opposite' ends. I put "opposite" in single quotes here because I find too difficult to phrase the point I wish to make, so I can only allude to it:
Reading Feyerabend without reading Lakatos carries with it the same (and not just similar or the opposite) problems as reading Lakatos without Feyerabend does - and vice versa.
The same applies to science itself, which kind of sums up the problem both of them approached, from 'different' sides.

I thus find it rather helpful to read the entire matter chronologically 'backwards', starting with 'For and Against Method' and then going back from there.
They've been violating the GPL license for years. The 'nuclear option' has been long past-due.

The End of Software: Will Programming Become Obsolete?
So if I take a truckload of 100$ bills, a bottle of gin and a can of gasoline, drive into the dessert, out of sight of the authorities, and burn the entire lot, then the next night all retailers will have a vision which tells them to lower their average prices by 0.573%?
No hard feelings :)

We're still less than a year old, so not at all sheepish about sharing whenever we can :)
I don't think it's an either-or thing. Getting better at programming will make you more effective in whatever domain you are working in. I think it's generally good to work on concrete projects but "what can I actually achieve with code I write" is heavily influenced by general programming skills. In my current domain of VR development the quality of product I can build is at least as influenced by my general programming skill set as by my domain expertise. Getting better results continues to require me to develop more expertise both in the domain and in programming (and I am already advanced / expert level in both so I don't think this applies only to relative beginners).
Thanks for all the great work on dev-tools. I recently started developing a chrome extension and found that not all of the great standard functionality was present. Here were some of the main pain points:

- debugger; statements do not work for me

- When right clicking the extension and clicking Inspect Popup, the first few network requests are not reported in the network tab (seems that it starts recording after the extension opens)

- It took a very long time for me to figure out that cookies were not being set due to this permission: (https://developer.chrome.com/extensions/declare_permissions)

- Hot-reloading extension code would be extremely nice

Even just extra documentation on dev-tools with extensions or tips/tricks for debugging extensions would be excellent - I haven't been able to find much in the way of docs. Keep doing the excellent work you're doing, just thought I'd give some suggestions :)
I should have said "significant sub-section", not implied HN as a whole.

I don't think it's controversial to say that the Ven diagrams of start-up loving nerds, and the type of entitled young men who have an axe to grind with FF are likely to have a non-empty intersection.

This is how most people work. They value their own lives and their own happiness over that of others. They will gladly buy their luxuries and let dozens of people die as long as they don't have to see them suffer. We all know this.

Just don't fool yourself. The reason we value our own happiness over the lives of others is because we are weak. That's something we have to live with, but it doesn't make it good.

>You could say the same thing about any other startup.

And I do!
Honestly, this is just the modern version of a process that has taken place since the beginning of time. It's called assortative mating. Basically, people tend to end up married to people who are of an equivalent class/quality/caliber. Now there is a dating app which augments the role of country clubs, private schools, and expensive neighborhoods in enabling the elite to find each other. NBD.

IMO, a much more troubling development is the way that the rise of college education in the 20th century has systematically pulled the cognitive elite out of most of the country and concentrated them in urban centers (where all the high paying jobs that demand elite cognition are located). Whereas the elites have always lived an existence far disconnected from the rest of us, now the upper middle class and lower middle class are similarly disconnected from each other.

Was the issue the socioeconomic class or the religious beliefs?

I can see how different religious beliefs can be a very practical issue but it seems like socioeconomic class is a little less "dogmatic" and it would be easier to find a middle ground? That being said I can't really give life lessons here, I don't think I ever dated anybody outside of my "socioeconomic class", whatever that is.
Can you elaborate a bit about the servers you used (hardware, cluster size, etc.)?
I have a related question. I had an idea many years ago and I've poked at it irregularly since. I have kids and I've already had one startup fail, so I just kind of slow-rolled this one.

I still believe the idea has merit, so I keep poking at it here and there. I spent money on design work and it's incorporated, but I don't have a partner or support mechanism.

I had a BizSpark account, but I "graduated" in February, so I can't host the API for free anymore. I was considering redeveloping the API in serverless AWS, but that will take time. I have a working API in .NET Web API.

So I'm I'm missing a place to deploy my API (and an Identity Server implementation for OAuth2) and an iOS developer to implement the designs.

Looking for advice...and sure, it may sound like I don't care enough and that's the death of many a startup, but I do care. I want to see the app completed and get a chance to work on the business model (and since it's a social networking app, that's no small thing).

All the good and bad advice is welcome.
> Sounds like you haven't ridden a motorcycle?

Repeating this is so unnecessarily condescending.

> In a hard right turn, you will need to keep constant pushing pressure on the right handle (steering left) in order to stay in the turn.

This is not usually true (though sometimes is at slower speeds.) Bike geometry and speed changes how this works a good bit [1][2]. Tracking my old 600cc, I'd need positive at slower speeds, but would need to steer into the turn once I had a good lean angle at anything 60mph+.

> You might want to google gp moto pictures before making claims, you can find tons of images of racers in the middle of the turn with the wheel angled outward. For example: https://i.ytimg.com/vi/dtCD63fKw58/maxresdefault.jpg

This is really uneccessarily condescending again. Also, that really looks a rider deepening lean as he rounds the apex. I'm thinking that wheel's not staying at that angle for long.

I encourage you to check the tone of your comments. Being rude to folks, especially while being wrong while doing it really brings down a community, and I hate seeing that happen on HN.

But gold has a use other than for trade.

If a bitcoin replacement were built on, say, folding proteins, then the information gathered has a benefit that outlasts the value of the currency.

Bitcoin only accomplishes two things: burn dinosaurs and slowly erode the usefulness of SHA2.

Maybe it improves the situation for ASIC manufacturers? I dunno. But gold improves the situation of wheelbarrow and shovel manufacturers just as much.
> The surprising bit is that when granting them the right to handle all internet traffic for the given domain (back in 2014), I wasn't expecting them to use it to generate certificates.

I hate to flog a dead horse, but considering you were specifically pointing the domain at them for them to host HTTP, them then securing that really shouldn't be surprising. If they'd started running other services on it (eg email) then I'd start being surprised. HTTP host hosting HTTPs though...

More granular DNS records would be interesting for the future. The ability to say "this host resolves to that IP but ONLY for web traffic and nothing else" (an "ahttp" record) idea intrigues me.
I've learned to ignore news articles that talk about what could or might happen. That's not news, it's just speculation. The news is supposed to be things that did happen.

Could elite dating apps exacerbate wealth inequality? Maybe. But people already segregate themselves by wealth pretty effectively. They would have to actually show that people who might have otherwise married someone of lower socioeconomic status didn't because of the app, and of course that's not available.

> On a societal level, yes it's bad when romance stratifies along classist lines

I disagree. It's bad when the society has poor mechanisms for distribution of the gains of economy, and with certain deficiencies the magnitude of the impact will be exacerbated by wealth-stratified life partner selection, independent of the degree to which this associated with romance. However I partner selection is not th source of the harm, it's a factor which aggravates the impact of some actual distributional defects if they are present.

It's not even a question that money helps but the question is how much and how.

It's also a question of what type of success were talking about as there are plenty of people from both less successful and more successful (pre MSFT) family lines that followed in their fathers/mothers footsteps rather than making it on their own.

If you are fortunate enough to live in a good/upper middle class home which values hard work and education and bestows it on you I'm not sure how much additional wealth and or power would be a factor if you are breaking on your own.

Both Bill's parents were very successful and hard working individuals with remarkable achievements I would even go out and say that his mother likely was more accomplished than his father considering the time and circumstances.

So at least in this case I wholly stand behind my assertion that how his parents lived had much more impact on Bill than their bank account.
