Why is there this assumption that everyone lives like some of you do in London, NYC, San Francisco, Boston and other large trend-setting cities where you can ride a bike to and from your pad and shit all over people driving cars? This article makes no sense to me having previously lived in a fairly large Midwestern city where a typical wait time for a bus is half an hour in the 'burbs with no other options but driving my own car. Public transport has to be a commonly efficient way of transportation everywhere before we even begin discussing taking parking away.

See, that's what I mean by "urban hipster lifestyle".

Outdoor dining can be done in backyards (pretty much every 2nd tavern in Athens, a big, sprawling, dirty city) does this.

Retail displays - pardon me, how many more do you need and why do they need to be in everyone's faces in the middle of the street?

It seems that millennials don't really know what they want and aren't flexible enough to choose from available lifestyles in different cities, countries etc. - instead, they what everything together immediately right in the place they live, no matter how contradictory those things are. If you want trees, go to a park. Kids can play there safely, too, without being run over by an ambulance or biker. ;-)

Clickbait headline. Real one is "Maritime Mystery: Why a U.S. Destroyer Failed to Dodge a Cargo Ship" emphasis mine
Frankly I've been wondering if there wasn't some arrogance involved on the part of the destroyer's skipper.
Do you have any empirical evidence this outcome would occur? Nearly everything I've read suggests the very opposite [1]. Further anecdote: I've been to many European cities with minimal cars, and many American cities ranging from super walkable to Robert Moses-esque highway-organized downtowns. The overwhelming trend is that car-unfriendly zones are the most bustling, and the car-streamlined zones turn to ghost towns after work hours.

That commander should be relieved of his duties at once. There is absolutely no reason a modern warship should have an "accident" like this. How could there not be automated systems screaming "collision course ahead".

This is the same thing as always, people are lulled into complacency and then accidents happen.
Have this image of the Navy, strict protocols, attentive crew all responding quickly to the commands of a hardened captain. For this accident to happen, nothing close to that was going on. It's hard to comprehend just how many people had to drop the ball for this accident to happen.
While the title is missing the "Maritime Mystery", I don't think this title could be considered 'clickbait' due to that omission.

> The problem is the high long term (dozens of generations) cost of favoring short term and small area beneficial strategies for a long period of time (millennia).

Can we counteract the effect (making long-term strategies more favorable) by politics, or by changing the way the economy works?
Don't what happened
Fwiw regulations actually have been getting more conservative on this. There was more confidence in the 1970s (when this tower was built) that modern concrete construction didn't require sprinklers. With the core construction material itself not flammable, and serving as fireproof separation between units, fires were supposed to be contained by design, with spread unit-to-unit throughout the building (especially so rapidly that it'd happen before fire services could arrive) not being possible due to passive suppression, and therefore not in need of active suppression. Which as you say may even have been true with the original design prior to interior ducting and exterior cladding changes.

In any case, in the past 10 years the consensus has been changing towards it being prudent to just always require sprinklers in high-rise towers. Scotland began requiring them in 2005, and England in 2007, but neither law is retroactive.
> Downtown? It's easy: they're noisy, annoying, polluting,

That's simply no longer true with EV.

> And yet, families with small children and businesses have been doing just fine in more traditional and not car-oriented cities.

In those fabulous city centers? Sure! Full of families with small children they are... ;-)

I admittedly never attended either one of these programs. My friend got an MBA from UCLA and has been extremely successful with that I will say. She learned a lot and felt it worth it.

What did the commander have to do with this accident? He was asleep in his stateroom.

Edit: The captain is responsible for his crews performance and the navy way means he'll never be given command again, regardless of the results of the investigation.

But my response was to someone who apparently thought the captain was gunning the engine while playing chicken with the cargo vessel. For one specific point, the destroyer wasn't on collision course, the cargo vessel was.
I agree with you that no one wants to spend an hour on a bus just to go grab a drink with a friend.

But why do you think the bus takes an hour in the first place? It's probably because we've dumped so much of society's time and money into making our car-system as efficient as possible. Therefore, the public transit is terrible in comparison.

Cars have encouraged so much sprawl in our suburbs. It allows buildings to be further away, because now you can travel greater distances. Massive parking lots then need to be constructed to facilitate the placing of our cars, which again, wastes huge swaths of land, further distancing buildings from one another.

In my mind, we can't make public transportation viable while continuing to massively subsidize private car use. The latter causes sprawl, drawing us into a feedback loop of even more private ownership, which then in turn causes even more sprawl, and so on. It's a strong reinforcement cycle.

We need to break free of this cycle, and I'm afraid the short-term efforts aren't going to be enjoyable, but it's all for what's best in the long run.
What would your answer be?

I would put "none of the above" on ballots, and if it wins, all the candidates are barred from politics or public office of any sort for life, and the election is re-run.
Thank you for the feedback!

Automatic simplification (as opposed to explicit conversion) is a complex topic. There are a few simplifications that are already applied, for example:

20 L / m^2
= 0.02 m

You are absolutely right, it'd be nice to have "Pa·m²" be converted to "N" automatically. I've been thinking about simply going through a list of simple, standardized units (SI units like Newton) while trying to convert the result into these simple units. However, notice that this is not always what you want. If someone likes to compute in imperial units, we would rather leave all quantities in imperial units.
As someone living in Colombia, I will give you a perspective:

The article compares Bach to Handel saying "not a single work of Bach’s is more beloved than Handel’s Messiah—and this is owing to that oratorio’s undeniable, ineffable charm," and apparently Bach doesn't have charm.

Handel's Messiah is popular in England because it was written in England, in English, at a time when English municipal choirs were really gaining popularity (choirs competed between towns, and police had to be dispatched to stop brawls, just like footballers today). Bach's work hadn't yet been translated into English yet, and by the time they made it to the islands the age of choirs was dying down (although Britain still has wonderful choirs).

As for the lack of charm in Bach, listen to this melody and tell me it doesn't have charm: https://www.youtube.com/watch?v=G5kc5IxtbBk

It definitely has 'charm.'

You should probably just buy a black and white laser printer. They're not much more expensive than inkjets anymore, have excellent Linux support, and you get hundreds of pages per cartridge.

Anecdotally mine occasionally adds garbage to the page, I don't know if this is for tracking or if it's just an artifact of the process, but I haven't really been able to trust a printer for years.
I don’t know what an “in control” military-industrial complex looks like, but I don’t think the current situation is unique to the US by any means.
Even discounting anything high tech, there's more than one person on watch, and the destroyer is much more nimble than a cargo ship. I imagine the postmortem will show a crazy breakdown across many processes.
The UK could run a larger deficit. The source / sums are done here: http://stumblingandmumbling.typepad.com/stumbling_and_mumbli...
I guess there was a deal in place to reduce the look-out crew and radar-crew- which where allowed to nap.
This would reduce the multiple layers of security to a single point of failure- which then happened.
For those who are interested in a relatively accurate (but dramatized) portrayal of what the operations on a destroyer look like you should watch the first and second season of The Last Ship. It does fudge a few details and its obviously a TV show that can't show anything close to classified material but it does give you a general sense of what its like.

I think it's been done. The Fitzgerald's captain is facing (EDIT: the prospect of) court martial, and had to be airlifted off the ship with serious injuries.

He will never command again.
The commander bears at least some responsibility for everything that happens on his command. The Navy will do a thorough investigation and probably lots of things will be to blame, but "he was asleep at the time" is not a get out of jail free card.
Some smartphones.
Not really the point. Read the section OP quoted, "YOU JUST DIDN'T LEAVE". Do any of those people sound like crunch was fun to them? They liked working on the game, and some of them reminisce about the crunch time like old soldiers telling war stories, but I don't see any positive adjectives in there. About the nicest thing anybody said was "when you're young you don't feel it that much," which is pretty faint praise.
True but he should not have allowed a climate/attitude where this could happen. It was his responsibility to keep his sailors at the ready and never allow them to become complacent.
Is this comment intended to be sarcastic?

If lookouts were not posted or the radar was not properly manned, the commander is ultimately responsible.

Heads will proverbially roll on this one, and his will absolutely be one of the first.
More than one process had to break down here, which implies some systemic laxness.
It was his responsibility to ensure someone competent to do so was on watch, so while it is a failure of personnel management rather than one of ship-handling, it is still the Captain's responsibility.
I don't get your response. OP said that bannning cars downtown would keep families, disabled people, etc. from enjoying downtowns. My point is that you can ban general vehicle traffic in the core downtown areas, but people with families can still get there by parking in a garage just outside the downtown.
The Crystal Bay is 294m and crewed by 20–25. It isn't very maneuverable and was most likely on autopilot. Yeah, the Crystal was for all intents and purposes a drone ship and the crew was probably asleep.

The USS Fitzgerald is 153m and crewed by 200. It is extremely maneuverable and is professionally navigated. While its AIS transponder was most likely turned off for security reasons, it has radar and an AIS receiver and deck watches.
Unless you think a shrimp is as conscious as a person, or that a dog is completely lacking in consciousness, you have to accept that consciousness comes in degrees. Unless you believe consciousness is supernatural, you have to accept that it has an organic origin. What that says to me is that humans have evolved brain structures that give us a higher level of consciousness than other animals, and IMO the best candidate for how that happened is we learned how to self-reflect through things like speech and art.
Show HN: Meatshields – An in-browser turn-based strategy game
A few months ago (82 days to be exact!) I posted a link on HN to my game, Meatshields. A bunch of you commented and played my game and gave me some wonderful feedback. Over the last few months I've been playing with many of you and implementing the best of everybody's suggestions.

So, thank you, HN for all your help! I feel this is an extreme overhaul I couldn't have done without your input.

Since then, I have: Dramatically improved our hosting platform (So it HOPEFULLY won't go down this time (oops.)), Added two new units, Rebalanced all existing units, Added many more maps, Improved the AI's threat-weighing algorithm, Completely redid the tutorial system, Added some real basic (and I mean BASIC) "animations", Redid the in-game UI (several times), And most importantly, HUNDREDS OF BUG FIXES.

For everybody who didn't see the original thread, Meatshields is a free, online, turn-based strategy game I made that is heavily inspired by Advance Wars. Those games took a very long time to complete in-person so I wanted to build a similar game online where players had many games going on at the same time and would log on once or twice a day to take their turns.

If anybody has any suggestions or bugs they encounter, please feel free to post them here. Otherwise, I hope everybody likes the game, and thanks again for the help!

It’s counter to the stated mission when it becomes entirely 1 sided and not beneficial. Wikileaks was meant to put an end to corruption, etc by revealing leaks across the world that benefit its local people. The biggest leak to do so lately, the Panama papers, wasn’t even by Wikileaks. What value are they providing?
Originally the tower was built out of concrete & the outer skin of the building was glass, steel (windows & frames) & concrete. The safety case for the building was that no fire could escape a single unit, or worst case a single floor as everything in-between the flats in the building was completely non-combustible. Hence the advice to stay in place until the fire service had put any fire that happened to start in the block.

Originally it was a safe building, even without sprinklers: there have been many fires (inevitably) over the years in similar buildings which have never spread, because it was impossible for them to do so. Sprinkler systems would have made them safer & perhaps saved individual lives in the past but at no time were entire buildings at risk because of the lack of sprinkler systems, because it wasn’t possible for them to burn.

Unfortunately, covering the building in flammable insulation (!) and even more flammable rain cladding (!!) completely broke this safety case, turning the building into a death trap.

This accident is actually fairly well understood and is a result of a particular aspect of naval and shipping culture that most of us never experience.

It is described in detail, with laugh-out-loud illustrations of boat paths, in an entire chapter devoted to these kind of accidents, in the excellent book _Normal Accidents_ by Charles Perrow.[1]

In short, very, very large ships are captained by egomaniacal captains who play chicken with one another - each of whom is certain that they have the right of way (due to ship size, military vs. civilian, etc.) These kind of accidents are nothing more than: "you get out of the way", "No, YOU, get out of the way". A very large cargo ship interacting with a US Navy destroyer is a perfect recipe for this kind of interaction.

Again, the illustrations of the boat paths in the book are literally laugh out loud funny as these huge boats slowly point directly at each other and crash or are on-course for near-misses and at the very last second veer into one another as they mistake who is turning where.

I highly, highly recommend this book - not just for the funny (but not that fascinating) chapter on the shipping lanes, but for the chapters on nuclear plant accidents and the challenger accident.

A working fire sprinkler system would have slowed down fire incursion and would have significantly reduced loss of life; as sprinklers have in many other high-rise fires involving flammable cladding. However, even an external cladding fire is dangerous, as burning plastics generate extremely toxic gases: hydrogen cyanide and carbon monoxide.
That's in the article, but it's pure speculation as applied to this particular event. It's possible the pilot screwed up or the missile just failed.
My bad. Thought I was cutting out junk. Updated to be less definitive on providing an answer.
The point is there are more shallow, cut-and-cover tunnels in NYC than in London. London has entire high-traffic lines that are deep tunnels.
The problem is, I think, that someone, something, somewhere, did detect the Crystal, but didn't act on it. The technology almost certainly worked right. It was likely the people that screwed everything up. The Crystal was probably on autopilot with no one (awake?) in the bridge and it would appear that the Fitzgerald was in the same state.

That said, for the US this is a pretty serious embarrassment, because it screams "not combat ready".

They are required nowadays, but weren't back in the 1970s when the tower block was built. I don't know exactly when the regulations changed, but existing buildings were not required to retro-fit them. There have been several calls to do so, not just after this fire, but after several previous ones too.

Ah,looks like I botched parts of this:

> However, if you could somehow assign a complex amplitude to each state in a classical probability distribution, you would still be limited to manipulating only one amplitude at a time.

This is probably just more confusing. What I should say is that classical probabilities have no physical manifestation that you can directly manipulate - they just denote our lack of information about a system. Amplitudes in quantum systems can be related to probabilities, but they don't represent lack of information. The probabilistic nature of quantum systems is deeper than that: measurements project superposition states onto classical states in a probabilistic way. This is

For exponentially large superposition states, there are an exponential number of amplitudes. When we act on the state in certain ways, we update all of the amplitudes in parallel. There is no counterpart to this when acting on classical states, even when you have incomplete information about the state (and thus an exponentially large probability distribution).

> But (especially) for the ones that do, I about the exponentially large set of amplitudes being manipulated in parallel.

you could only apply simplifications that minimised the sum of the absolute value of all the unit exponents. that would be intuitively satisfying, and not require converting imperial to metric (which would leave the exponents unchanged)
That looks like a living butterfly.
Thank you! "bel" is already supported ("decibel" also, due to the handling of SI prefixes). Unfortunately, "dB" is parsed as "deci-byte". While this is not really a useful unit, this is on purpose (see https://github.com/sharkdp/insect/issues/67) in order to support "kB", "MB", etc. for "kilobyte", "megabyte", etc.
