> Sure, but it's not 6X more expensive in the suburbs. Water / Gas lines, for instance, are often under sidewalks or yards now so you don't have to dig up the road to replace them.

Sometimes. Digging up sidewalks and yards is also expensive, regardless.

> You don't have to. When utility work gets done in the suburbs, people often just lose water / electricity / gas / whatever for the 24-48 hours while they do it, and just have to deal with it.

I've never been anywhere that 48 hours without electricity or water was considered acceptable for maintenance. In my experience, most maintenance is done during business hours with the expectation that people have utilities when they get ready in the morning and when they get home.

24 hours without a major utility is generally considered an emergency and crews are driving in from other states to help.

> Even after adjusting for inflation, it's only about 2X the cost of a driveway, not 10x.

You're probably right that the 10x number isn't accurate, since I completely made it up. It's still a lot of money and the cost to replace is always higher than the cost to build in the first place (with perhaps the exception of cost for grading).

> And that's my problem with the article. It seems they took the actual cost of infrastructure, "imagined scaling it up maybe 10x", and then claimed a crisis using their imaginary costs. Real infrastructure costs, while high, are simply not anywhere near as high as they are claiming.

I feel like you're nitpicking their claims without providing any alternative data or a compelling reason why their numbers don't make sense. You're asserting that they arbitrarily scaled up costs but you've not shown that they did so. The author is a civil engineer and a PE and a city planner so there's some weight behind his claims. You're asserting that his numbers are lies because you don't like them.

I'm not sure where your "6 times per generation" replacement claim is coming from, either.

> The price crashed today because the BOC visited BTCC. I think that's obvious

This is a good hypothesis, but it is far from obvious.

I remember, years ago, unwinding a portfolio of correlation trades. The trades consisted of bets on how assets would correlate, e.g. Apple might be expected to correlate with Microsoft more than with Société Générale, a French bank. We were under a time crunch to unwind the massive portfolio. Given the structure of the trades, unwinding them meant reversing their implied correlations. Thus, for one week, the market's largest names anti-correlated with reference to how a few traders had previously thought they should have correlated. The moves were noticeable; the attribution far from obvious. Nevertheless, talking heads proceeded to breathlessly blame political crises in Spain.

To properly attribute this Bitcoin activity to the People's Bank of China, one would want to examine country-level Bitcoin flows of funds around the time of the PBoC announcement, paying attention to hourly data around when the Chinese- and English-language announcements were made/leaked.
> I don't know the exact details of her situation, but it seems like perhaps the correct decision would have been to sell the house and move to a smaller, more efficient house if the current house is too expensive to maintain given the number of occupants and their age/level of income. I'm 24 and currently rent half a large house in the suburbs from a single guy in his 60s who needs the extra income to maintain the house which he bought when he had a larger family.

In California, this can be difficult to impossible due to Prop 13, a voter initiative from the 1970s that caps the rate at which property taxes rise.

Doing some back-of-the-envelope math, given that Inglewood has a median house price of about $450,000 [1], if Ms White were to move to a median house in Inglewood (probably a much smaller house since she has a five bedroom right now), her new property tax bill would probably be about $5220 [2], compared to the $1215 she's currently paying. This isn't quite as high as her property tax bill post PACE loan, but it's pretty close.

In other words, Ms White can't really move; it would wreck her cash flow nearly as bad as this PACE loan.

The flip side of this story is that Inglewood's (and the rest of CA's) home values are probably inflated due to Prop 13 -- lots of people like Ms White become trapped in their homes due to the massive property tax increase they would realize by selling and moving, which reduces the supply of available homes, driving up the price of those that do sell.

In a sane world without property tax caps, Ms White and other landowners wouldn't be insulated from rising property values and probably would have worked with their government to temper rising property values with new housing units. Inglewood (city of about 100,000) only added a meager 1000 units of new housing [3] in the 13 years to 2012.

[2] property tax rate of 1.16%, which is probably about right -- in CA there's typically a 1% county assessment baseline plus any bond assessments.

I used BlaBlaCar a couple of times to travel between Berlin and Hamburg. It was great, and I've wished there was an equivalent here in the US for traveling between NYC/Philly/Boston/etc. In both cases I traveled with people that were making the trip regardless, and I got the impression the money would just help cover gas, not really make a profit.

> The major difficulty traditional local newspapers have faced over the past two decades is this downward cycle

IIRC, It's more like 4-5 decades, and while the cycle is approximately correct for the positive feedback loop now running, it didn't, as I recall, actually start with declining revenues, it started with a wave of newspaper mergers (and acquisition of newspapers by non-newspaper firms) and attempts to increase profits after those mergers by reducing costs, which got you to the step you label "20", and the cycle took off from there.
> When you say "substance" what you mean is physical goods

The citation of AT&T and JetBlue by OP seems to disagree with this, so I don't necessarily agree with this reinterpretation of the OP's analysis.

As an example, one could argue that companies involved in self-driving R&D could very easily meet this definition as a provider to the bottom-line of society as transportation to/from a location is a service not terribly dissimilar to providing data and communication. By that token, Tesla and soon Uber could soon fit this bill as service organizations (disregarding Tesla's manufacture of vehicles).
We do a few things:

1. Regular strategic planning which includes a community survey. This is conducted by an outside firm and non-users are targeted as part of the survey. We also do focus groups.

2. Interlibrary loan. You local library can likely get titles from other libraries. This should inform the collection.

3. Patron driven acquisition. Some way of suggesting books should be available. We buy most suggestions and find that books that are suggested circ better than ones selected by staff (generally, anyway).

Nice, this looks great for regression testing
Just a guess, but those people probably updated their installation with an existing (insecure-by-default) configuration in place. Very little software like this will mess with an existing configuration, so that upgrading doesn't appear to break anything. That's how they'd be on a secure-by-default version but still be insecure.

Sounds a lot like translating a web app after it was released. In a company I was working on, we made a commitment to call out strings without gettext as a bug, regardless if it was really was going to be used for a single country/language.

Indeed.

Mark Twain's quote is also often misunderstood. It doesn't mean you should never be in the majority, it's about always questioning your choices.

Personally, I go one step further and I always pause and reflect, whether I'm in the majority or not.
It's not throwing away if you were going to flood that currency anyways, and just used BTC instead of gold as the intermediary.

I did the math above, and if you wanted to save money on attacking the network with your own mining, you could spend up to $71 per transaction on every transaction.
The sheer unpredictability of Bitcoin even bites those who try to use price manipulation to their advantage though at times.

Look at what happened with pirateat40, the "bitcoin savings and trust" ponzi scheme king who couldn't pay out one time and decided to try to try his hand at market manipulation instead.
I first started using Mongo in 2013/4, when I deployed my app, first thing I did was to change the default port and add authentication, as the manual recommended. I'm an accountant who's a hobbyist developer. I knew very little about security then, but I read the manual.

The insecure defaults were an issue sure, but anyone installing a piece of software in production without at least reading up on config options needs to find another job.

I've used BlaBlaCar in Germany. They have buses operating in a similar niche as Greyhound/Megabus (cheap but slow). Compared to those, the BlaBlaCar option was maybe slightly more expensive but faster and more comfortable.

Wow, you are really good at HN - Thanks for this. :)
Interlibrary Loan aside, if you live anywhere near a university with an academic library, you can usually buy a membership even if you aren't otherwise affiliated with the university. Locally, I know both UNC and Duke offer programs of that nature. I have previously kept up a UNC library card so I can use their math/CS library. Which reminds me, I should probably go renew that... I haven't been over there in a while.

Also, used bookstores, and Internet retailers like Amazon, Ebay, etc. Not all books that are "obscure" are necessarily expensive in the "rare, hard to find, valuable" sense (although to be fair, some obviously are).

Startups take several years to exit.

So isn't it perfectly normal that it also takes several years for the total value of IPOs and acquisitions, i.e. money that flows out of startups, per year to catch up with the rising trend of total startup investment, i.e. money that flows into startups, per year?
True, but datazyne comes out to be crazy expensive.

Yeah - I don't mind if unwrap panics with a dev-oriented message as it's basically an assertion, but I guess I expected expect() (no pun intended) to give a more user-friendly error. Maybe the format of the panic! output could be changed to bring the message to the front and the technical details after that.
>There are at least 2 sides to every loan - the originator and the borrower - and it helps to examine dynamics on both sides of the table.

You've kind of hit on a huge part of the problem - there's WAY more than 2 sides. Thanks to swaps, derivatives, and bonds, the originator isn't on the hook if the borrower defaults. The originator isn't even holding the loan anymore. They've bundled it up and sold it off to a 3rd party who never bothers to check if the loans are any good, because THEY bundle it up and sell it off ASAP to a 4th party. Repeat ad nauseum.

End result is that nobody in the chain is ever incentivized to actually check if the borrower can afford the loan they've been given. On one side, you've got a giant billion-dollar industry who whose best interests are served by issuing as many loans issued as without concern for the long-term consequences. On the other, you have the borrower. As we learned from the 2008 crisis, putting all the pressure solely on the borrower to think of the long-term consequences is not only unfair, it's dangerous to everyone.
The main study and previous evidence being cited here says that it wasn't disproportionately low-income loans that caused the financial crisis:

> Taken together, the evidence in the paper suggests that there was no decoupling of mortgage growth from income growth where unsustainable credit was flowing disproportionally to poor people.

It was still a subprime crisis if the crisis was caused by unsustainable credit received by those who would not otherwise have had access to it.

They are saying it was not the Community Reinvestment Act (CRA) that caused the crisis, as the contributing loans were not subject to CRA legislation.
Defaults are stupid and dangerous.

First off, there's the constant problem of default passwords. The big IoT compromises lately were due to default passwords, and ever since they became popular they've been a bane to security everywhere. Wifi APs used to use defaults, but luckily most come with a randomly assigned password now (except those provided by an ISP, occasionally). All software that matters should not use default passwords.

Second, a "default" is not intended to be an operational setting. When developing software, a default is literally a placeholder setting so that your software won't immediately crash if a configuration value is missing. Some software is effectively meaningless without a configuration, but if they are obscenely permissive they can allow a user to still take advantage of it, which is how MongoDB is set up.

Finally, there is effectively no such thing as a secure default, because something isn't really secure until it's been vetted through a process. Pretending your software is secure when you have literally not given it a second thought is just setting you up for eventual disaster. People should be actively thinking about their security if they care about it; defaults just leave them blissfully ignorant.

In my ideal world we would require software to no longer have defaults. Demand that users be aware of the configuration and running of their software so they understand what's involved with how it runs. This would teach them more about the software they're using, which would enable them to take better advantage of it, as well as make it more secure. If you don't have time to do that you probably shouldn't be using it.
> The mayan's number system is base 20 (though the digits are are drawn out of sub digits in base-5).

I think I remember learning in school that one of the ancient Mesopotamian civilizations (Sumerian, I think, but I could be wrong) used 60 as the basis for their system because it was divisible by 1, 2, 3, 4, 5, and 6.
It's absolutely valuable to have a place to find obscure books... but a community public library isn't that place, and isn't intended to be that place.

The Making of the Atomic Bomb is a classic, award-winning and relevant book. It's exactly the sort of thing a good community library should have, even if it circulates less than Danielle Steel. There is a big difference between what's important and what's popular.

Those Danielle Steel might provide some entertainment and comfort to people (nothing wrong with that). But The Making of the Atomic Bomb could launch a career or a movement, and possibly even -- we can only hope -- save the planet from destruction.

Truly obscure and unimportant books should of course be culled from circulation in a small community library. Their place is in research libraries, etc. But community libraries serve many purposes, the most important of which, in my mind, is to educate and facilitate discovery and personal growth.

Sometimes you have to give people what they don't know they need yet, not just what they think they want right now.

None of that has anything to do with bitcoin and the PBoC news. This is the third time this week where PBoC news came out and the price tanked immediately. Whether this is fear over the PBoC, or fear of fear over the PBoC, doesn't matter to the point at hand.

The problem here is monopoly, or mono culture.

The whole world is, basically, using one email client. The lack of diversity means a well written scam like this spreads easily.

I can say for certain I'd never fall for this scam -- because it looks like crap in Pine. I know I'm special, but the same applies to Thunderbird, or whatever.

There's probably a parallel to biology here. Let's get diversity back in our internet culture and with it resistance; scams like this will be harder to convince and much less likely to spread. Hopefully removing some of the incentive, too.

"Third, because of the freedom extended by the two most popular open source licenses these infrastructure vendors can host successful open source projects without constraint. And because of their scale, they can do it at a fraction of the cost by the startup would."

My personal social media experience at Nextdoor (which is focused completely on the local), and I know this is anecdotal, is that that a lot of the people cut out the big, over-dramatically sweeping hyperbolic politics when the topic / scope of conversation is more localized in nature. At least, I mostly see reports on the neighborhood, events and complaints, services advertisements, etc. People have opinions, of course, but its not the binary hyperbolic type stuff that personifies too much of national politics (and sadly tends to leak over on too many Facebook posts).

(From this viewpoint, I'd see a model like Nextdoor an easier fit for a local news initiative... Facebook's scope just seems too global at first glance for them to do a very good job.)
