Very real risk for developing transport infrastructure... Would checks against this kind of malicious intent be on the digging company, or on the city planning departments that determine route alignments, etc.?

(Real question - I don't understand the relationship between technical contractors and cities in this context.)
Hi @justsorneguy, Mattermost team here. Thanks for the mention! What can we add to Mattermost to improve?
I agree with that and I'm certainly not advocating that the rest of the Bay get developed as densely as SF. As a city, SF very clearly needs a lot more housing and a transit expansion, maybe even a merger with Oakland as a borough, with greater transit connectivity there and density to match in Oakland.

The problem then becomes that the rest of the Bay would most likely get pressured to build more densely as well, just like the metro areas of NYC did. That might ruin the suburb life that you enjoy as the expanding city to the north puts pressure on the surrounding areas.
>I don't quite understand. The scholars of Europe did not have access to Aristotle's works. Are you saying that isn't true? Was Spain isolated from the rest of Europe during the Middle Ages?

Uh yes? Spain was part of the Umayyad Caliphate and then various other Caliphates until the Reconquista ended Islamic Spain in 1491. Islam never lost Aristotle.

Saying that Europe largely lost Aristotle isn't propagating the myth, repeating Hegel and Descartes Eurocentric views is, as is saying civilization is fragile when it survived fine.

A lot of the reason the European's liked old things is that they could then claim it was European knowledge rather than Islamic. Examples include Aquinas commissioning a translation of Aristotle from Greek sources, as the existing copies were translated from Arabic.

As for sources, yours only shows that Aquinas rationalised Aristotle and Catholicism, which is true. On what I've said, if you didn't know about Al-Andalus I don't know where to begin. Anything about the Umayyad Caliphate would be a start, or almost any modern history of the age.

I'm also completely ignoring that the "Fall of Rome" happened in 1453, largely considered the end of the Middle Ages.
This argument doesn't make sense because doing it like that is even worse that JSX.
Because cars, which are relatively wasteful spacewise, create negative externalities on the public transportation by causing congestion, which resultantly makes public transportation less efficient.
Water leaks are not going to be a problem on mars. Significantly lower gravity 3.711 m/s vs 9.8m/s also drastically lowers pressure from burrowing.

The trick is in the mix. 100% clean energy (wind, solar, hydro) might be somewhat of a challenge. But it is rather easy to raise its share of the total energy production to about 80%. The rest would be provided mostly by gas, and perhaps a very few coal plants, which would run only in absolute emergency times. This would reduce our carbon footprint considerably. And for this, the additional cost is very small, if not already money can be saved. When we are at 80% renewable, we can then discuss the technical and financial requirements for the rest.
The high speed is the "overelaboration". High-speed rails in many countries can reach 200mph. A 600mph train may be 3x as fast, but the marginal utility is pretty low to me compared to increased cost and reduced capacity.
> If you want cars to be more closely packed, travelling at higher speeds and controlled by computers

Isn’t that called “a train”?
A feature somewhat similar to `marginalia` is probably going to merged into Rails very soon: https://github.com/rails/rails/pull/26815
With all my sympathy for metro - in many American cities it will never be good enough due to extensive suburbs.

In places where land is cheap, and there are single family houses, cars will be the most efficient way to commute for years to come. We'll switch to self-driving electric cars, but still.
Its not the stupidity of the companies, its that you have a hammer and not everything is a nail.
There are noncomputable functions. For example:

you are right, Waste heat would be a problem because the only way you can dissipate it is by radiation. but that would become a problem much much farther out. I mean we are talking 100+ billions people.

Also, if you have plentiful energy you can build way cheaper orbital launch tech. translation you are not bound to earths gravity well anymore. So its not too far fetched to imagine living in space habitats (forget mars that just good for gravity). those will be much better at dissipating waste heat (volume/surface area thing).

Like I said its a whole another ballgame.
Australian Government Just Shocked the Natural Gas Markets
Wide-open spaces, even enclosed ones, can reduce the psychological burden of confinement quite a bit -- there's a variety of Russian strategic-missile submarine with a swimming pool, for example. This subject also comes up frequently in SF (science fiction, not San Francisco, which has the opposite problem); there was some discussion of it on the "Atomic Rocket" worldbuilding guide, IIRC.
It's basically saying that the universe is a special kind of computer that computes state transitions according to the rules of physics, presumably at the planck scale, which is far beyond what our simplified models of said rules can manage.

This view of he universe seems to be fairly important and taken seriously since black hole thermodynamics, gravity as entropic force and similar concepts are derived from it.

Right. It's prudent to assume that the NSA intercepts all Internet traffic, and stores as much as they can, for as long as they can, focusing on what seems most important. Everything is retained for a few days. Then they triage, based on names, addresses, keywords, and so on. Metadata and encrypted stuff, they reportedly retain indefinitely.

Citation, please! I'll start with Wikipedia's page, of course:

https://en.wikipedia.org/wiki/Climate_change_mitigation#Cost...

>Which is based on...assumptions pulled out of somebody's behind.

No, absolutely not. They are based on data. And projections.

However, if you're going to assert that it's impossible to know anything, than my estimates are just as good as yours, and I say it's going to save us $100 trillion/year! Tada!

Economic models are subject to manipulation, just as a business model is, but that doesn't mean that none of them have any credibility.

The credible answers, the ones where somebody has tried to make honest efforts, have mitigation costs as a tiny percentage of current GDP. In the US, that could be easily paid for by the amount of government waste in defense.

“Show HN: Podcast Search and Alerts App”
https://itunes.apple.com/us/app/leela-next-gen-podcast-app-player-with-search/id1117733751?mt=8

There a lot of podcast apps out there but most of them require you to know what you want to listen to and some even require subscribing to a channel before listening to any episodes offered by that channel. We created Leela to offer an easy way for users to find and listen podcast episodes.

Some of the unique features:

1/ Sends daily notification on newly published episodes that match your interest (think of it like Google News Alert Service for podcasts).

2/ Search podcasts like you’d expect it to work.

3/ Rate individual episodes

4/ Share episodes

We are adding more new features (ability to search within a podcast channel, non-stop episodes based on topic and many more) including Android App support.

My vision is to make it super easy for EVERYONE to be able to listen to free audio content offered by podcasts.

Would love feedback from the community.

Leela is free and downloaded by thousands of users in 15+ countries.

Cheers,

Just tear down the Gardiner and build public transit everywhere. The traffic will evaporate as people change their behaviour, just as we've seen in Paris and other jurisdictions that have removed road capacity. https://pricetags.wordpress.com/2017/03/30/paris-road-closur...

There's no need for this absurd fantasy tech. We can solve our transportation problems with the very basic tools we already have.
5K iMac + two P2415Qs is what I'd ask for. Depending on how much travel/client meetings maybe a tablet or cheap compact laptop.
The quote is quite explicit - 'If you tell a story chronologically, you're more likely to be fabricating it'

I'd argue that my response isn't hyperbolic, and is justified considering how ludicrous that statement is.

How do STAR and SOARA not dictate chronology? You specifically discuss the initial situation first, and the results you achieved last (or the analysis of the results).
The appropriate setting for a statement timeout could really depend on the application. 5 seconds is probably sane for 90% of applications, but the other 5% may have a legitimate need for longer running statements.
Because they make my tummy feel nice and warm.
It's still incredibly wasteful compared to a real subway. The amount of people a real mass transit system can move is orders of magnitude above tons if individual little cars:

http://penguindreams.org/blog/self-driving-cars-will-not-sol...

..not to mention all the energy required to move each of those vehicles compared to a train that can move hundreds of more people in a similar space.

Americans need to get over all their train/bus hate. Other countries love mass transit. Many Americans try to shoot down any attempt to even put in a small system (small systems can grown) and kill off attempts to grow existing systems (see the Seattle Green Line).

Self driving cars can work great in Europe, where there is tons of transport and you just need to solve the last leg (or where self-driving trucks are rented just to move large items). In America we have massive gridlock due to a lack of rails and that needs to be fixed before self driving tech will fix anything.
Canada does not have a population large enough to actually have stewardship over the territory contained within its borders. The tax base simply isn't there. Effectively Canada is a 100 Km or so strip to the North of the United States a bit wider in some places. If you want to really claim all the land up North that is barely in use you'd need a population at least 10x the present one and even then it would be a stretch.

Infrastructure and defense costs are closely related to surface area and border length if you want to keep world class powers out of your backyard.
This is impractical in SO MANY levels...

Commuter rail is a thing. DC's metro goes a dozen miles outside the city in all directions and the MARC train goes further.
It's good for you to point out how little the headlines represent the actual content of the articles, much less the science itself.

For example, that 2007 article:

"In the end, it will just melt away quite suddenly. It might not be as early as 2013 but it will be soon, much earlier than 2040."

Which lines up with the 2017 article.

Mmm, so I spoke too soon on that front. In my defense, I've said this a lot to people who are advocates of Hyperloop construction (vacuum tubes are far too easily ruptured to be used in conjunction with transportation), but Musk is correct.

Are subways targets for terrorism the same way that airports are?
"Edited: Way too many people haven’t noticed this is satire. I’ve seen an article on Facebook claiming $100k isn’t enough to live in the valley, and then another one claiming $130k isn’t enough. Then there’s another Twitter employee complaining with $160,000.I wanted to make a hyperbolic next step to show the stupidity of those articles. There are service workers living with $10k or less. Working in tech, you should be fine with your salary. Stop complaining."

I understand this is intended as satire, but I don't think it succeeds on that basis.

Hyperbole based satire certainly can be used to reveal an absurdity, but sometimes the hyberbole involved in satire is exactly what turns a reasonable position into an absurd one. Although it is true that people make it in SF on less than 100k a year, I don't think it's reasonable to use a satire based on a single person earning 250k a year to tell people who earn 100k that the should be happy and stop complaining.

I noticed that this analysis left out childcare. A quick google search shows that the average cost of childcare per month is 1,900-2,400. If you want the kind that allows two people to work full time, 2,400 isn't a bad deal.

You also need housing, especially if you have two kids. That's going to be expensive. It's very unlikely you'll get this for less than $2500 a month in rent.

As for not complaining... honestly, most of the people I know with kids in SF and are hard up for money don't complain much, they get on with it. It's the Silicon Valley tech employers who constantly complain about hiring woes. These companies often refuse to allow remote work or find a way for workers to live in places where 100K would be a wonderful salary for a family.

As far as I see it, it's those companies that are constantly complaining to congress about a shortage of workers.
Fiberglas boats mass-produced ~20,30+ years ago have been holding up well (depending on maintenance). So they are relatively cheap now. Something that was really mass-produced like the Catalina can be bought for like 10k for a 27 foot one.
You should check out this comment from elsewhere in this discussion by someone that seems to have done good original research:

Pretty sure GP means yes. Bread literally just needs flour, salt, yeast, and water. White flour has little to no oil. Whole wheat flour does but the oils to go rancid too quickly. You don't need just-milled whole wheat flour to make good whole wheat bread. White flour doesn't need any added oil.

Edit: Anyone interested in learning to cook, Americas Test Kitchen Cooking School (And also Cooks Illustrated Cooking Science and Science of Good Cooking) would probably be good for much of HN's audience. It is much more of a cooking "textbook" than most cookbooks. It explains what you are doing and why you do it instead of just a big list of recipes. There is also Modernist Cuisine but those are really pricey.

> Its still Canadian territory and Canada still gets to control who goes through there.

In theory. In practice Canada has neither the resolve, the funds or the strength to put that into practice. I'm not sure that's a bad thing either, the fact that Canada technically owns it but does not start drilling like mad or doing other bad stuff that far up North at least keeps things roughly as they are for now.

On the contrary, I was saying exactly that: since the rights aren't inalienable but contractual in nature, that holding up a flight to the point of refusing to comply with law enforcement is not the way to go about a contractual dispute.
Is the main radiation danger the Sun or the background "cosmic" radiation?

I've been assuming the latter, but I realize now that I don't actually know.
City streets have more than enough space for fast transpiration. We just don't use them efficiently. Congestion is a tragedy of the commons. It could be trivially solved by putting a high tax on cars using city streets. Then the only vehicles on the street would be those that transport multiple people or valuable goods. And they would have free reign with minimal congestion. (Also maybe put an extra tax on nonelectric vehicles, because there's much less justification for using them in a city.)

If you are willing to build entirely new infrastructure, like this project, there is so much you can do. The main reason self driving cars are taking so long is because they have to be able to do everything a human driver can do. Which is very hard. If you build tracks and sensors into the road itself, it could be much easier. You could have a city filled with fleets of small automated electric people movers.
Yes it is. Cars don't even begin to match the capacity of trains. Look at London or Singapore where trains arrive less than a minute apart at peak hour. Many of London's trains are autonomous and all of Singapore trains are fully autonomous. There is no way individual cars could even come close to matching that kind of people-moving ability.

Scraping is only one part. How are you going to categorize, store and search the data !?
It's not thought provoking, it's a series of thought terminating cliches.

I'm as liberal as they come, I'm very sensitive to disguised racism, but the tweets' entire basis of comparison between Musk and Moses is "both are/were ambitious men and now musk is talking about infrastructure". It's free-association garbage.

The Moses story is fascinating because he accomplished great things that built NYC but was also a horrible person. The tweeter you linked is like, "hey, Musk is trying to accomplish great things, he must be just like Moses".
With the warning that it's using Idris and strict semantics rather than lazy, I'd almost agree.

The NSA calls getting the data "interception". It calls LOOKING AT THE DATA BY A HUMAN WHO IS AN NSA EMPLOYEE "collection". It considers there to be no limits whatsoever on "interception" and permanent storage of communications data. It considers there to be some minor legal limits on "collection".

We can assume the NSA will continue to intercept approximately 100% of the world's communications, and store them in Utah, and "collect" them when legally feasible or desirable.

This story is, at best, a trivial change in NSA operations, and more likely, zero change in NSA operations. (The NSA is permitted to lie to you or the press about its operations.)
All public transportation is.
As someone else said the platform itself is not sane.

However on the scale of things that we have, React is pretty sane.

I have never seen someone who spent significant time with React and thought it wasn't sane.

There are some people who are stuck with some 2005 MVC jQuery PHP AJAX mindset repeating worn-out lines like "don't mix logic with views". All their alarms go off when they see JSX.

I don't for a moment think any of this crap that we have is "elegant".

I hate TypeScript/Javascript/React/Redux/Webpack/JSX/Yarn/NPM/Node etc... and I also love them and use them.

Those things that I listed in 2017 enable a class of web applications to be created that is simply not practical to build with send-html-from-the-server-and-sprinkle-jquery-event-handlers-on-the-client technologies.

At this point it's Javascript vs everything else.

I used to build applications with PHP/Laravel/Django/Flask/Sinatra etc... now I don't consider them anymore for web applications (still ok for content sites, not complex applications).

The smooth robust magical UI/UX that I can achieve with TypeScript/React is miles ahead of all other options, it's still full of crap, but still miles ahead of other options.

Again I re-iterate my main point, which is things have now changed in such a way that the competition has become Javascript/TypeScript vs everyone else.

If you are going to build HTML in a string on the server and sprinkle some javascript on top it doesn't make that much difference whether you use PHP or Python.

So they are somewhat similar to the problems Elon tries to solve with rockets. Rockets are not normally reused, which makes them expensive to use.

They are often custom built (at least partly) and thus not mass produced. While we won't see that for rockets any time soon, it believe he managed to bring down the cost of building rockets and continues to do so (he uses his own money after all and does not have the support of every tax-paying citizen like NASA used to during the Apollo missions).

Sure the engineering challenges are probably different for the most part but the economics are the same. Rockets are more expensive then they should be. Boring is also more expensive then it needs to be.
