The author's numbers don't add up:

* "In San Francisco, the median house price – half sell for more, half sell for less – is $1.37 million"

* "The monthly mortgage payment for the median house in San Francisco, after a 20% down payment and at the prevailing rock-bottom mortgage rates, is $6,740 per month"

Bankrate.com says the average (not rock bottom) 30-year fixed-rate jumbo mortgage is about 3.9% today (August 17th). Wellsfargo.com actually quotes an APR of 3.6% on a 30-year jumbo, which corroborates as that's probably closer to rock bottom.

Using Google's mortgage calculator, a 30-year mortgage @ 3.9% on a principal of approx. $1.1m ($1.37m - 20%) comes to a monthly payment of approx. $5,200.

The quoted figure couldn't have been inclusive of taxes, because in the next paragraph he emphasizes that monthly payments would be even more with tax and insurance. But in any event, the rate in SF is about 1.18% (at high end) which brings a monthly mortgage + tax to approx. $6600 (rounded up).

I don't mean to contend with his main point, but it's sloppy and disingenuous to fudge and exaggerate these numbers. It also calls into question his other numbers. And as a rhetorical matter there's hardly any need as nobody disputes the severity of the situation.

Maybe I missed something. But even so, San Francisco offers other options. For example, it's one of the few places in the country where a bank will finance the old common law form of ownership, tenancy in common (TIC). TIC is similar to a condo, but you own the building in common with the other tenants, and use collateral contracts to stipulate that each tenant is limited to occupying his portion of the property.[1] This happened because San Francisco restricts the number of condo conversions each year, so lawyers and banks revived the TIC concept as a sort of legal hack. A TIC unit will sell for considerably less than a comparable condo.

[1] A condo is the reverse: each owner has title only to his unit, and contracts and other entitlements are used to spread responsibility for maintenance of shared spaces and the building as a whole.
Yeah, I think that's probably the split - folks from computer science/discrete math on one side and folks from engineering on the other. I grew up in math, but I was on the numerical analysis side so I definitely ended up on the MINLP side, which is why that's what I generally reference. There is certainly something elegant about ILP problems which gets lost when treating them with the sledgehammer that is gradient-based convex optimization.
Slashdot's moderation still had some problems - which might be inevitable, I don't know.

There was a big bias towards early comments - moderators had to see your comment before they could upvote it to the top of the page, but once it was at the top more people would see it and keep it there; so a comment that would score well if posted as comment 10 would score nothing if posted as comment 50.

And karma tended to reward /popular/ comments, which were often things the hive mind agreed with, rather than high-effort comments. Discussion about DRM? Get in early with "DRM is impossible because" or "format-shifting should be a right" for a quick high score.

Oh now, the best investment decision anyone has ever made, was Masayoshi Son buying a third of Alibaba for $30 million or so. I don't think shorting Aramco is going to get you a ~2,500 fold return in 14 years.

Yes, but they have very cheap production costs which makes their oil more profitable than the average barrel. They have loads of it still in the ground. And finally they also refine and make other petrochemicals. It's quite a valuable firm.
The point here is that how can you make sure the keys are right, if the attacker might also replace those?

I think words are very powerful, in particular "microservices" vs "monolith". By accepting those words, we imply the conclusion: microservices sound sexy and lean and elegant - who can argue with separation of concerns? And a monolith is a big unchangeable rock.

I think we need a better word for apps that are single tight self-contained systems than "monolith". You can design elegant interfaces, and avoid creating a sloppy mess, with function calls or objects too.

Thank you, I am adding it to my shortlist.
It's not so cut and dry. One reason Aramco is worth so much is that the cost to extract their remaining reserves (on a per barrel basis) are one third of costs in the U.S.

A collapse of oil prices may decimate the energy industry in the developed world (which extracts from offshore or unconventional sources) and would mean Aramco becomes the only supplier. Now obviously they wouldn't be able to raise prices beyond a certain level, but they have many decades of guaranteed cash flow remaining.

Obama Administration: SF's Anti-Gentrification Plan Promotes Segregation
Well, I would suspect that the US is much more culturally diverse than Russia. Something like a quarter of all US residents are foreign born or have a foreign born parent; that's reflected in cities like NYC. I am doubtful the numbers are similar for Russia, which is very large and does have some ethnic and cultural diversity, but has been dealing with the same groups for much longer and probably in more of an authoritarian way.

Not a defense of America; I do think the difference is more complicated than just the size.
It might be helpful to mandate every submission to an academic journal to be accompanied with a maximum 800-word "layman's summary" that will be directed at the media and the public.

They're trying to get out now by selling to suckers who don't realize that most of their oil assets are worthless. I don't mean that they've falsified accounts of how much oil they have, I mean that most of it is going to stay in the ground because it won't be worthwhile to pump it out.
I don't think it makes sense to expect the median mortgage to be for the median home. For one, all cash sales would appear in the latter data set but not the former.
For news sites with a paid component, they could allow comments only from subscribers / donors. Having a gate which involves money will improve the conversation somewhat. I'd even go a step further and make comments invisible except for subscribers. People creating trial paid accounts could see the comments but not comment themselves. This latter step would prevent astroturfing from firms willing to pay $10 for a trial but not $100 for an annual subscription.

Moderators would still be needed but their workload would be reduced. And there would be money available for them since many would subscribe / donate just to be part of the community, which would make moderation less of a drain and more of the core profit-making.
The website is vulnerable in a much larger number of ways, since it involves significantly more infrastructure which is all vulnerable to state actors. A state could generate fake certificates, physically access hosting servers, or access the internet connections the website uses.

There is a much smaller attack surface for keys.

If you are talking about protecting the key fingerprint they posted on the website, the idea is by publishing them now that others can note the fingerprint and warning before any malicious actor would have a chance to respond.

This is also the same key they've used in the past I believe, so it can always be compared to prior releases.

> A state sponsored attacker can reasonably easy generate a valid ssl certificate to man-in-the-middle any website, and replace it with what ever they please

Doing this against bitcoin.org is probably taking a pretty big risk. Remember that misissued certificates represent proof of their own existence, and, if disclosed publicly, should result in an investigation of how the certificate was created.

They could also choose to start using HPKP and asking browsers to report pin failures. Then a browser that has visited the legitimate site before will report to someone if it encounters an inconsistent cert in the future. That would make using a misissued cert for this site into an even bigger risk.

Yes yes yes, but better yet, write your own. Micro ORM's are "micro", it's pretty trivial to create something better than Dapper and there's no framework in the world better than your own, to you, because there won't ever be anything to complain about, just mold it to work exactly how you like.

Dapper..

var dogs = connection.Query<Dog>("select Age = @Age, Id = @Id",
new { Age = (int?)null, Id = guid });

yuk, I prefer

var dogs = Dog.FindAll(And(IsNull("Age"), Equal("Id", guid)));

A touch of generics done properly, a bit of reflection, a static import, and you can do much better than onnection.Query<Dog>. Write the API you want, implementing what is basically an active record without relationships is not terribly difficult and will pay off for years to come in your own code.

Edit: Dappers API is ugly as fuck, that's an immediate non-starter for me, and the cost of reflection on loading objects is the wrong problem to be optimizing and would only show up in an absurd micro benchmark intended to show off speed that doesn't matter, it's small compared to the execution time of the queries. If you like it, use it, but lets not pretend it's so much effort it isn't worth redoing. It's certainly not the end all be all of ORMs.
Pretty cool. We were recently discussing how a service like this could exist. Excited to try it out.

One suggestion - on the Signup page, you ask for a lot of permissions right away from Github. I think it would be better if you just collected profile/email address and then when I started exploring a little more and working to get my first site deployed, only then ask for the additional permissions.
I would add VS to that, and potentially Unity/Unreal? Also I imagine corporate and government environments that use windows might also hamstring their developers into using it.
Did you think about just templating your static stuff? You're not going to get new portfolio entries every day and you likely don't need writing staff accounts, comments, or anything similar that CMSes are about.

If you either template what you have now, or go with something from https://www.staticgen.com/ you get a few benefits:

- no upgrades necessary, no security patches, no incompatibilities

- you can host yourself trivially

- you can host literally anywhere, including just sticking the files on s3
It looks like UberWAV in NYC provides app-based access to the existing fleet of wheelchair-accessible taxis: Uber will find a taxi and dispatch it to where you are, and you pay taxi fare. That technically works (assuming the dispatched taxi shows up), but I'm not really sure it should count, especially because Uber's obvious goal is competing with taxis and driving them out of business.
I feel bad about what Windows has become. I really thought that Microsoft had turned a corner with Windows 7, which I really liked, but every release since has been disappointing.
I know that on HN, we shouldn't downvote unless something doesn't add to the discourse, but I'm pretty sure th13 is just factually wrong, his arguments are weak, and it really doesn't add much to the discourse (e.g.:

I think the fact that it's difficult to find examples of this is proof that there's not as much of a slant as you think there is.

Core doesn't actually have a huge standard library. That's kinda the big problem with it. It's basically, at the moment, a really shit version of .Net 4.61.

For example in the 1.0 release the ORM is a complete joke at the moment. It can't do fairly basic stuff, like worse than ORMs from 10 years ago.
Every time I see an article like this, I wonder whether these experts have put their money where their mouths are. I'm sure there are plenty of Uber investors willing to take the other side of this bet, especially if you think the company is worth less than half of its valuation. Otherwise, it makes it hard for me to believe their opinion.
about the only positive thing that can be said for Uber is that people love it, it fills a need, the alternative is to own a car or pay cartels inflated taxi rates, and people must absolutely must get from point A to point B - they have no choice but to fill that need somehow, and also I suppose it could be said that Uber has shown an incredible ability to execute to the extent of lobbying to rewrite antiquated laws and regulations as well as educating consumers and building infrastructure and operations, essentially creating a new service category through innovation, it has uber-high mindshare and strong, honest sales and revenue.

But take away all of that, and what is left? Nothing but a a service people hate and that nobody needs, where their needs are met elsewhere for free, and by a company that has no ability to execute or deliver it or history of doing so or any revenue from doing so. In essence under this scenario the only thing Uber would still have is the ability to convince investors to value it at $60B.

Incidentally, this is the only thing that is necessary for it to have a real, honest-to-goodness value of $60B. All of the first part is not what gives a company its value (though it can't hurt) - the second part is.

Why there would be any sudden shift in sentiment or valuation by investors is not something that anyone has advanced. . . why would they suddenly turn on uber?
ok, still they have %20 of world reserve. so oil reserves worth 10 billions and %10 of world economy! in US we have more oil consumption than any other nation, do you spend %10 of your money on oil???

I wonder whether you saw the article last week about how difficult it is to actually short Uber.[1]

The reason all that "sharing economy" stuff works is that you can afford to have worse capital utilization if you ignore existing regulations. For example, there's a big difference between what people can afford to pay for hotel stays and what they can afford to pay to live somewhere which means that dedicated AirBNB apartments can stay empty a large chunk of the time if you ignore zoning regulations intended to block this. Similarly, Uber cars can operate at much lower hours and mileage because there aren't the same restrictions on the number cluttering the streets or the same vetting of new staff.
That oil will still be worth trillions for the next two decades. It won't be worthless until the global economy has moved very substantially off of oil. It won't even plunge toward worthless until demand begins to dramatically fall off, which isn't going to occur in the next two or three years.

The Saudis will likely have time to liquidate a very large portion of Aramco and its oil assets before the market for oil dries up too much. In 20 years they can exhaust over half of their oil reserves (by some estimates, they'll be a net oil importer by 2030-2035). They'll sell well over ten trillion dollars worth of oil in that time.

It will take decades to shift the global economy and industry off of oil. In ten years, the majority of cars on the road globally will still be burning gasoline. That hopefully won't be the case in 20 though.
Hmmm. That idea is definitely appealing, but the "platform" argument has some serious negative side effects that I think the government should legitimately be able to regulate. What if babysitters of one race didn't want to sit babies of another race? Should they be forced to?

This isn't a hypothetical example—Airbnb has this exact problem.
> > I love that there are many people on here clamoring for physical copies.

> even at the cost of trees, environment,

We grow trees to make paper. That's how the paper industry works. Nobody complains about us devastating "virgin potato fields" because we use potatoes to make chips. But the logic is precisely the same. There are more trees _today_ than in the 1950s because of the paper industry (as well as tree planting efforts). So if we stopped using paper cold-turkey, we would remove the financial incentive for companies to plant more trees.

> I suspect it is because of the sucky "format-hell" of ebooks and sub-par reading experience.

For me the real issue is the licensing. I think that it is intolerable that a company can claim that you don't own ebooks. It's a slap in the face to traditional freedoms of readers and is incredibly chilling. Amazon deleting copies of 1984 and other books from every kindle on the planet paints a precedent that should be taken very seriously. Not to mention that their product line is literally named after fire-related terms (perhaps subconsciously implying the purpose of the products is virtual book burning)! You couldn't make this stuff up.

Companies that sell PDFs which are licensed under free licenses are much better, but the other issues you mentioned still mean I probably won't buy ebooks for a while. I prefer physical pages.

Hi Cup - yes you're right, what people are looking for in their career is complicated and varies by people.

This is part four of our career guide; the first article is all about what actually creates job satisfaction: http://80000hours.org/career-guide/job-satisfaction . I think we say everything you said on your comment, and a lot more.

While people are varied, there are a few factors identified in the psychological literature that are highly predictive of overall job satisfaction and fulfillment for most of us. :)

I like the argument made in So Good They Can't Ignore You, which is in line with this article. Specifically, the author argues that based on studies, people most satisfied with their jobs are not those with a natural aptitudes for their work.

Rather, job satisfaction is well predicted by (1) expertise in the given field, (2) quality of coworkers, and (3) freedom to do what you think is right. For me, I'd say this is pretty accurate.

Generally, there are a few popular models of job satisfaction: https://en.wikipedia.org/wiki/Job_satisfaction.

Right, the span in this case is an extra tag that you don't need. Nesting an input tag under label has always struck me as having ambiguous meaning. Are you saying that the checkbox "belongs to" the label, or maybe "is a child of" label? Shouldn't it be the other way around, if anything?

One of the accessibility guidelines of the WCAG is that content in your markup MUST flow in the same direction as it is rendered on your page. This is recommended so that screen readers will read the page aurally in the same way as a sighted-user would read the page visually. If you follow that guideline, then placing your input tag before the associated label tag in the DOM usually makes sense because that is a common visual ordering for those elements.

The 'for' attribute in the label tag has semantic value that the span doesn't, you're just adding that span so that you can use the CSS combinators. If I squint, you're DRY, but once I unsquint I think YAGNI. :)

Seriously though, it really is a social good to strive to make your page content accessible both stylistically (for the low vision users, color blind users, etc.) and semantically (for the screen reader users).
