You'll get about 10 metres in an office with cubicles with chest high partitions. Page 6 of the paper "A High Speed Wireless LAN" by Skellern, Lee and others in the Jan/Feb 1997 edition of IEEE Micro has a diagram showing coverage for OFDM in a typical office at a centre frequency of 40GHz. 60GHz will be worse than this, as oxygen in the air absorbs 60GHz quite stongly [2]. I'm not sure how the power transmitted by 802.11ad compares to the above measurements, but the measuremensts in the paper were taken with 60GHz WiFi in mind, so they should be representative.

Edit for clarity. And I should also mention I'm an author on that paper.
She she does travel to high school, so presumably she sees kids her age regularly. And presumably she also has access to the rest of the public transportation that does not go the the highschool (unless she is the only one in the town to use public transportation to go anywhere), so she can still socialize in other places.

Plus, she can socialize with people not her age.
Generally speaking, the population of Japan is going down and the population of the Greater Tokyo area is going up.

Once youth hits college or working age, they disproportionately head for the capitol.

But then there's a small counter current where younger (say, 30's) are moving back to their original prefectures as they realize that they might be able to afford a better QoL making less money but also paying much less in expenditures.

Here is quick history of the AI field.

We need to creating thinking machines, but we dont know what is thinking so lets take any human activity that requires thinking, oh chess is such a game, lets build algo to play chess, yeh it works and beats humans, but can we say it thinks? hmmm hmmm not really coz this algo can't play any other game .. dammit this is not AI. We are stuck.

We need to design algos that can do a lot of different tasks and not just one like playing chess also these algo should be able to extend their capability rather than redesigning them. Hmmm lets use general purpose "search" algos (LOGIC programming) and also feed lot of "knowledge" into the algo as input. Yay we got expert system and they almost looks like thinking. Let's see what else can we use them to do and someone shouts "lets see if they can recognize image", dammit that's so hard to "represent" using "knowledge bases". We are stuck.

Lot's of people kept working on how to "represent" the algo and inputs for the problem of image classification and similar problems. Came up with various "machine learning algos" including "deep learning" algos which seems to work really really well but of course they have their own demands like huge amount of data and computing power etc. But are they really "thinking" ??? They can be easily fooled, they are like black boxes nobody can extract some useful knowledge from trained network such that it can be used somewhere else just like general purpose knowledge we humans have. This is the latest shiny thing as of now. But we don't have general purpose AI yet.

We always want silver bullet and we always hope that we will get there by creating hype but in the end the hype dies and people move on to next hype.
What do you expect from advanced radio equipment?

Each new hard drive standard has required a faster motherboard to take advantage of it.

WiFi standards are backwards compatible in the sense that they work with older hardware to send at the maximum speed that those radios were capable of transmitting.

Lovely story. Hats off to Japan Railways. I'm also happy that The Atlantic/Citylab decided to publish this story. And thanks 'hudibras for submitting it here!

They say that it's the money that makes the world turn, and love only keeps it together. It would be easy for the Railways to ignore that girl. There's no economical reason to keep that station open. It's a waste of time and resources. And yet, someone decided to make that random act of kindness, for a single passenger.

It's a symbol. It represents the best side of our nature. That even in this big and complex world, full of heavy machines and complicated systems, we're still humans, and we care for one another. That we aren't slaves to the processes we brought into existence.

Random acts of kindness like that are happening every day around us. I think that as a society, we need to pay more attention to them. They bring hope and inspiration, which is infinitely better than yet another outrage.

And that girl, she will have one hell of a story to tell to her future friends.

Wouldn't it be both cheaper, and friendlier to the environment to hire a person chauffeur for her? This is outrageously inefficient. Public transport only becomes worth it when it achieves relatively high ridership.

Symbolic integration doesn't converge in that way. More strategy is required, and you're not guaranteed a closed form solution.

However, if a closed-form solution exists which can be expressed in terms of the operations + - * / exp log, then it is guaranteed to be found.
There's a general term for these things: ghost stations (https://en.wikipedia.org/wiki/Ghost_station).
It would be even friendlier to the environment if she wasn't formally educated. Will educating her really provide that much for society to make it worthwhile?

6 of the Top Relaxation Techniques
This station is on an existing, operational line that would run trains on the tracks even if she weren't there (and this is what is going to happen once she graduates).

So the marginal cost of stopping at this station is actually not that large.
I hope some move back. From what I've seen/heard, the countryside is suffering radical population shifts. The following article has some great graphs to illustrate the point. There is a giant dip in the 20s (school) and a terrifying peak in the 55-60 range. But the greatest disparity is that there are many many more old (70s) than teenagers in the countryside. Across the nation those two groups are roughly equal.

Consider also the energy it takes to do those maneuvers. And that the station needs to be maintained; even though it doesn't seem to be staffed, the cost of keeping it in shape over many years was likely nonzero. I am not a train expert, but I suppose that stations require additional infrastructure - like lights and semaphores - which also needs to be maintained and regularly tested. Then you can start pricing in the opportunity cost of the land that could be sold or put to different use. And the organizational overhead of adjusting schedules to match the girl's lesson plan. It adds up to some considerable costs, of which the company management was surely aware...

...and yet they chose to ignore it. That is indeed just beautiful.
The train is already going past the existing station, so I would imagine the additional cost of supporting the station for the two times a day the train stops there is relatively small - additional brake dust in the air, some extra energy burned.

It wouldn't surprise me if the accounting/management, HR and maintenance overhead for the station was higher than the cost of having the train make an extra stop twice a day.

It is a little surprising the station appears to be staffed based on the picture of the train schedule, but there is something to be said for producing that extra job. I am sure the station master who resides in that office is really happy it still exists.

One thing that comes to mind is that for any former USSR country geopolitical considerations come into play. Unless you're willing to spend more money on this than Russia is willing to and able to procure other resources that Russia has readily available (military, etc), you're done.

More generally speaking, even as a thought experiment, the main obstacle is that the actual corruption is the tip of the iceberg -- or the flower that blooms from the plant and the roots of a civil society that operates in such a way. I don't know whether anybody ever succeeded in changing civic culture from the top down. I'd be surprised and I'd expect that this would require the use of violence unacceptable to anyone that minds corruption. My guess is that the only way towards a healthier social culture is evolutionary.

I think that the only way strong civil societies ever developed historically is in the conditions of gradually increasing prosperity or at least the standard of living above subsistence that gives the luxury of a bit of toil-free time and that little extra buffer of security that you're not constantly under the immediate risk of being hungry and homeless tomorrow if something goes wrong.
In a man eat man environment, you do what you have to do to survive. There's significant evidence with multiple meta-analyses at this point that anxiety has strong effects on attention and cognitive performance (e.g http://www.tandfonline.com/doi/abs/10.1080/08917779108248762). There's a good reason why, as per de Tocqueville's astute observation, revolutions occur not when bad conditions get worse, but when gradually improving conditions suddenly become worse.

The slightly better-off and the rich face different issues. Multiple studies suggest that the rich in societies with high inequality are a lot more anxious and less satisfied with their life. It's easy to imagine why that might be -- the costs of falling down the food chain in a highly unequal society are very serious, and the perceived threat from the have-nots is substantial. (Now, inequality in a society where the lowest incomes are far above the living wage is probably far less of a problem.)

Ancient Greece & Mediterranean, pre-industrial Britain and other European countries after the population-culling blessing of the Black Plague (I'm not kidding), the US, fertile North & South of China before and after 0 AD all had conditions of some sort that made starting down this road of growth a bit easier.

It's of course a catch-22. We don't really know how to engineer strong civil societies and prosperity, for all our chest-beating. The evidence is abundant. Because of that, I think that we ought to be a lot less dismissive about "increased standard of living without freedom" that China is often accused of. I think we know of many more examples of prosperity producing strong civil societies than the inverse.
HSV might result in rather artistic results with appropriate saturation and unnatural hues. I'd love to see the results.
Japan has a immense centralization of jobs in Tokyo (and to a much lesser extent Osaka). It's "go make your fortune in New York", but 10x as extreme.

They've been talking about the need to decentralize for decades now. The earthquake showed the risk of centralization and having a single point of failure for the economy and the government (famously, some foreign companies moved HQ and/or datacenters to Osaka). Nothing has changed though. If anything things are becoming even more centralized.

There has been minority political endeavors talking of introducing the concept of "States" to Japan to structurally support this sort of decentralization. At times attempts have come close to fruition (most recently Hashimoto's attempt in Osaka), but none have borne fruit.
I was there to hike up the nearby volcanos, so taxis weren't practical. I gather there are some amazing museums and churches, but the city's main outdoor features seemed to be smog, litter, and protruding rebar.
It's sad but some older minority folks grew up fearing white racism or hating whites, and never wanted to integrate. Maybe it's just a small irrelevant data point, but a friend's grandmother went to her grave hating whites because her white teachers from elementary through high school would tape her mouth, and her sister's, with duct tape for hours for speaking Spanish.

The reality is that we live in a racist world, which continues to perpetuate because blacks / Browns and whites are divided, for the most part, across economic lines that will take a long time to be erased, and those economic lines create cultural lines that are harder to bridge.

We were one of these potential bigger customers willing to fork over thousands per month, but the unit cost was still too expensive for us. We tried to negotiate a better bulk rate, but their team was unresponsive and so we eventually went with another service that was more responsive to our needs. According to the article they only have ~3k paying customers, which means they only care about giant top tier customers willing to pay top dollar. Seems like a mistake to me, but what I only know from the potential client perspective.

It could be. It depends on how the costs of that extra stop and related overhead (maintenance, management) compared to the costs of sending that chauffeur and related overhead. I suppose it is inefficient, but not outrageously so.

But you know what would be the most efficient option, from the point of view of the railroad company? Just ignoring the girl and closing down the station. That it didn't happen suggests that someone, at some point, decided that sometimes you have to sacrifice efficiency in order to be human.

(It's actually a general observation - in current highly optimized economy, being human and humane creates inefficiencies. Or in other words, we need to keep some things from being perfectly optimized, in order to avoid living in a misery. Compare to e.g. various laws protecting employees. They purposefully make businesses less efficient, in order to ensure that employees can work in safe and humane conditions.)
A Leveraged ETF is designed to amplify (and possibly invert) the daily returns relative to some benchmark. So for example, SPY is the "normal" ETF which tracks the S&P 500 index. UPRO is a triple-leveraged ETF which is designed to get 3x the daily returns (gains or losses) of the S&P 500, using the same amount of capital. Some other ETFs are leveraged and inverse, meaning they will gain value when the index loses value, and vice-versa. In general, day-trading these ETFs is a way for small traders to increase the leverage on their bet. However, there is always some sort of "friction" with using leverage in this way, which causes the all leveraged ETFs to slowly lose value over time. Intuitively, you could say that you taking out a tiny loan in order to increase your bet, and the friction is just interest payments. Maybe somebody else can explain some more technical details, if you are interested (I recommend financial blogs such as Kid Dynamite's on these types of topics).

Here are some examples of levered ETFs... sorry, it seems most web UIs are interactive and actively resist linking to a customized chart. I'll link to the benchmark. You'll need to click "Compare" and enter the two leveraged ETFs, be sure to check the "Display as a Percent Change" option, and then mess with the duration (from 1D through 5Y is illustrative). You can see that daily or short-term returns are inverted relative to each other, but long-term returns (6 months or more) are net negative across every pair of ETFs.

Small caps (e.g. Russel 2000): TZA is 3x, TNA is 3x inverse. IWM is a proxy for the benchmark.

Financials: FAS is 3x, FAZ is 3x inverse. XLF is a proxy for the benchmark.
http://www.barchart.com/interactive_charts/etf/XLF

Bottom line: for buy-and-hold investors, leveraged ETFs are always a trap.

The thing is, they (the headline) say "Japan", but this only happened because it's way out in the countryside where people have a "village mentality" of helping each other out (but the trade off is that everyone sticks their nose in your business). Japan railways itself split into several separate companies upon privatization.

This would never happen in Tokyo. As much as we think of the country as being monolithic (in many ways it is), there are great differences between different regions of the country (much like any country).

Tokyo is a place where a train being 2 minutes late causes ire (and a train conductor once killed himself for a mistake as trivial as this). It's a place where if a person jumps into the train to kill themselves, many will curse under their breaths about being late to work. It's a place where if you faint in the train concourse during the morning rush hour, no one will stop to help you. It's a place where young mothers with strollers are given stinkeye on public transit. If you ask someone (in fluent Japanese) to take a photo for you, you will often be completely ignored. Tokyo is cold.

I agree with you that this story represents the good in us all. But Japan is like a black box to those who don't live there. I would caution you against idolizing it on a national level as a result of stories like this.
I guess I'd have to disagree. People are typically not "walking around", they are mostly walking from A to B at fast pace. Nathan Philips Square might be an exception due to the skating rink.

Also last few days might be an anomaly due to the unseasonably warm weather, but during a typical winter the scene is quite different.

Again I wasn't totally bashing Toronto, there is some interesting things to do here. Christmas Market used to be nice before the 30 minute lineups started, and during summertime there are definitely a lot of buzzing events or chill places to just hang out. Or maybe I am boring and tend to see the uninteresting side of my city. In this case I might need to make some more cheerful friends like you.

No, the station isn't staffed since 1983. I think the photo with a desk, books and timetable is a waiting room.

Well ratcheting premiums upward is not the only way to increase profit. Same premiums with reduced number of claims at adds to the profit too.
Heart-warming story but too much praise for the government for my taste.

What are the opportunity costs of not shutting down this platform years ago? And of getting the train delayed by 40s twice a day for who knows how many passengers plus some minor costs like acceleration, meetings to change the schedule etc. Considering all this it would almost certainly be cheaper to provide her with a taxi at the train cost, maybe only to the next train stop. Maybe given the choice of getting a taxi twice a day or getting the compensation in cash, the girl would even have taken the money and moved closer to school.

The new investors used the real estate only to sue the first company to get money – after the first company went bankrupt, no one rented the real estate again, it’s empty now.

It wasn’t "at market rates", it was far above that, and just intended to bleed out every piece of property from the company and transfer it as profit to the investors.

One main problem is that you have to make passwords recoverable. In real world message like "warring! we can't restore your key!" just doesn't work at all. People ignore it and still want you to recover their keys. Also forcing people to have password is also very vulnerable.
