I'm actually the person who added these planets to OpenStreetMap, so it's somewhat funny and incongruous to see them appearing on Hacker News.

Incidentally, your walk of about 3 miles sends you within a couple of hundred meters of the partial ruins/remains of a medieval palace (16th century), a Norman church (11th-14th century), the site of the Anglo-Saxon Battle of Otford (776), and the archaeological sites of two Roman villas (1st-3rd century). If you widen out by another 500m, there's another Roman villa, and an iron age fort up on the hills.

It's very unusual in Roman Britain to have three villas so close together, and there is speculation that one of the sites may be a temple complex. Lead weights were found which could be unrolled to reveal curses - 'I HATE CLAUDIUS, MAY HE BREAK HIS LEG' sort of thing. They were apparently thrown in for the attention of the local river goddess.

The third villa site has just been discovered, and excavations by the local society are actually underway this weekend.

There are a number of other villas dotted northwards along the valley, and one open to the public with a series of famous mosaics, and the earliest evidence of Christianity in Roman Britain, at Lullingstone.

Otford during the Roman period would have been a significant centre of power, it is at the southern point of the river Darenth, which flows north into the Thames, through very productive agricultural land. To the south is the Weald, which would then have been a massive forest stretching almost down to the south coast and the English Channel. More than one Roman army entered that forest and never emerged. So for the Romans Otford and the Darenth Valley would have been both a breadbasket and the edge of civilization.

It would also have then important as a crossing point for the river, and the point where the river cuts through the North Downs, a set of chalk hills which run Eastwards and then South East, to Dover. Those are the same hills that are cut by the Channel to make up the White Cliffs.

Now, it's a rural or intermittently suburban area, strong banker/commuter territory for the City of London (it's mostly countryside and small villages, but Canary Wharf is only 20 miles away, so house prices are off the scale).

Anyway, my vague point is (beyond being mildly interesting), if you're in London on holiday, or in fact if you live in London, I recommend hiring a car and wandering off into the Green Belt and going to somewhere like this (although it could be pretty much any direction, go 15-20 miles outside the M25 orbital motorway from London and you'll hit the countryside). You'll get a much better idea of England (which is surely above all about cricket on the green, pubs, cream tea and village churches!) than by getting entirely sucked into the tourist maw in London.
There's one cellular provider which has the obligation under CALEA to do wiretaps. They comply with the law strictly, which annoys the FBI.

First, CALEA requires that the company provide a "senior official" as a point of access for law enforcement, and a backup 24/7 contact. Their senior official is their general counsel, and the backup is another lawyer. It's not their network operations center. Their general counsel wants to see a warrant, and checks back with the court to make sure it's valid. This is the way to do it; bring in Legal.

There's a procedure for "emergency requests" in advance of a warrant under CALEA. This telco immediately faxes the law enforcement requester a brief form to fill in for those. It requires name, police department, office address, badge number, and a brief explanation of why there's no warrant yet. The form to be signed by the law enforcement official contains a statement that the official will provide a warrant within 48 hours, and in the event that they fail to do so, their department will take full responsibility for their actions, including indemnifying the telco against any costs and damages. That's followed by a statement that in the event the law enforcement organization fails to authorize the actions of their official, the official will be personally responsible for said costs. The telco also reserves the right to disclose requests for which a court order does not follow.

This discourages fake "emergency" requests. Get your legal people to draft something like that. The key to this is that law enforcement's interface to your company should go through your legal department.

(I used to have a link for this, including their forms, but can't find it now. Can anyone else find it? )
It really depends on which team you're working on. There's plenty of toxicity to go around
Why? If you were investigating a crime, you're in law enforcement. Officers of the law have an ethical duty to obey the law, perhaps a stronger duty than those of us who are not sworn to uphold the Constitution or some other higher document. Law enforcement officers also have better knowledge of the law and what it requres of both officers and people/businesses with data.

If I were part of a business, I would be obliged to follow the laws about giving away data, so I would find out exactly what my legal obligation is, and follow that as best I could. If that means asking for a warrant, I would politely, but firmly ask for one.

I'm thinking of getting one of those doormats that say "GET A WARRANT", personally.

It's still worth something if the request doesn't go through, and the radio doesn't waste energy transmitting advertisement information. For me faster page loading is not the motivation for blocking ads: I don't want things vying for my attention, and I don't want ads taking up mobile data or energy from the battery. If you care about page speed only, make your own decision about whether or not to use the app. Feel free to contact me for a promo code.

Here's a demo video of MadBlocker in action:

If APs are cheap, you can get very high capacity by deploying more APs and managing transmission power so as not to step on adjacent APs. The trick is to make the radios smart enough to make coverage good enough without having a carefully designed deployment of APs.

Hopefully we can leave the antediluvian idea of "spectrum ownership" behind.

Budget time for clean up after you get the deliverables. If you're bringing on the right person, hopefully they won't leave you with pile of messy code. But even if it's mostly clear and organized, giving them paid time to increase the maintainability and DRY it up will pay dividends in the long run. Obviously the trade off here is that it costs more, but that's something you'll have to consider for yourself.
Some may argue it do improve someones life as pure mathematical elegance, even if not 'applied' to the 'real' world.

So, reading between the lines, the SYSTEM TABLESAMPLE algorithm appears to be biased toward small values (in bytes, or whatever the on-disk encoding of Postgres values is).

If you choose random data pages (of fixed size), then it can fit more rows of small size than of big size.

"In the query above, SYSTEM is the name of the chosen sampling algorithm. The SYSTEM algorithm chooses a set of pseudo-random data pages, and then returns all rows on those pages, and has the advantage in running in constant time regardless of the size of the table. PostgreSQL 9.5 will also ship with the BERNOULLI sampling method, which is more rigorously random, but will take longer the larger the table is."
One obvious reason is that I want to hear the parking sensors beeping clearly. :)

But in general when starting the car or parking, I want to hear as much of the sounds around me as I can. It's not that music is a big distraction, but it's blocking other sounds. I want to hear the engine of a nearby car, I want to hear kids running on the street, people talking, etc.
Well, an island only makes it really expensive for people to visit that place because there can only be so many people in that island. Making it an inland city will at least remove one constraint.
This looks fun. Last week I cycled from Pluto to the Sun on the Somerset Space Walk. The scale is something like a million kilometres per pedal revolution. And it took seemingly ages to get from Pluto to Neptune...

It's interesting - all (I think?) the people interviewed in the article sounded like they worked in non-dev roles. Might not be the case, but it might explain why your wife hasn't had the same experience.

So you're saying we should transition to an economy that's less dominated by organizations that exist solely for the benefit of shareholders? Perhaps co-ops are the future.
Attention? Neuroscience? Talk about overthinking a problem. I lost respect for the article when it didn't use the word "noise" even once.

There is a little bone/muscle combination in your ear (??Tensor Timpany??) that acts as a gain control. While you drive, the background road noise causes your ear to reduce its gain. This makes all noises seem less and protects your ear. Then when you stop/park the road noise is gone, the muscles relax, and the music now seems louder. So you turn the volume down because it is uncomfortably loud for you, not due to any sociological or neurological factors.

This is why you need to turn the volume up in a convertible. It is also why people sing louder in the shower because, to them near the white noise of the water, they don't seem as loud.

And this process causes stress onboard planes or other constantly-loud environments. That little muscle in your ear gets tired. Stress around loud noises is partially a physical rather than purely psychological stress.
That's a really excellent point. As I was reading it I thought maybe the author didn't really get why the IOC exists, but your suggestion, that this is mostly satire, makes way more sense.
I love PG, and don't plan to ever move away from it.

But I'm starting to wish they had in-place upgrades. Application I develop is getting to the point of "too large to make a copy of the whole db whenever I want to upgrade Postgres".

I can postpone things for a little while by replacing all our large objects with a external file storage -- but the tables themselves are growing quickly.

That'd be my favorite "big data" feature.

Automorphisms of strange structures like this are connected with the constellation diagrams that got us from 4.8 K bits/sec up to 57.6 K bits/sec and beyond on modems. They're also used in designing block codes and error correction codes.

The interactions between graph theory and group theory are deep and productive, but not immediately obvious, and occasionally convoluted. There are others here who can talk more knowledgeably about the details - not my area.

It's also the case that pursuing these sorts of things purely for the sake of solving the puzzle can turn out to be of value, even if there are no immediate and obvious applications. Graph Theory and Combinatorics were just curiosities originally, but have turned out to be critical in many, many areas, not least coding theory, processor design, algorithm analysis, and much, much more.

Sorry, I didn't mean to disparage Law School. I assume it's valuable as well.

But the barriers inherent in medical training are really far and beyond pretty much any other field -- you need a bunch of dead bodies and a lot of very expensive equipment. By the time you pay for just the materials necessary for the series of tests and exams that would reasonably certify someone to be a doctor, you might as well make a degree program out of it.

So even if someone could get all of the book learning and also find a gaggle of doctors to study with and learn from, Medical School is one of the very few professional programs where having a degree program would still make sense, totally independent of learning and development, just from a logistical standpoint. In that sense Medicine is pretty unique (unless you count graduate degrees in experimental sciences, I guess).
So much waste would be reduced no null. Instead of being left with unmaintained and useless infrastructure similar to case of Beijing: http://www.reuters.com/news/picture/ghosts-of-olympics-past?..., facilities could be renovated continuously for fraction of price, that could eventually be covered solely by cash inflow of hotels and advertising.
Do you even have anecdotes to back this up? I'd prefer some kind of data, a citation or a revelation from you, but even anecdotes allow me to consider internal consistency.

Lately, I'm becoming very suspicious of infosec people who imply huge threats, or mystical capabilities.
> You only have to look at the consequences of the Snowden revelations. Nothing has really changed...

So your evidence that the public doesn't care about the revelations is that the government (who are the perpetrators of the spying) haven't changed their ways? Could it instead be because when selecting candidates to vote for (for the minority that do vote, which is a separate problem), Americans have prioritized other issues? Do you think that the survey I cited was methodologically unsound, or that people were simply lying?

How about the fact that private companies are responding by changing their platforms to be more resistant to such data collection even under warrant, and publicizing the fact? Why do you think they are doing that, if not to appease the public?

> And my comment about Americans being Authoritarian is nothing new - they've long considered to be Authoritarian.

By who? You? And whether or not the government is authoritarian, how does that imply the people like it?
The WC is a waste as well. It's even more egregious actually, because there are more than enough existing stadiums to play the world's most popular sport. Yet FIFA still insists on new stadiums being built for just a few matches.

Well, not directly, but: Watering your lawn is (a) expensive, and (b) seen as wasteful. So most people never water their lawn at all, only letting it survive on rain water, or they collect rainwater from roof collectors and water with that. Usually, not a single liter of household water ends up on the lawn.

And most Germans use toilets that never fill the bowl and only rush about 1 liter of water to save water (the new ones without poop shelf, at least).

Why we do this? (a) efficiency, (b) water is expensive, even though we have more than we can use.

Actually, in my city people use so little water that the water company (despite population growth) has to clean the pipes artificially, because they were designed to self-clean from the constant water stream, but people just don’t use enough water for that. (Why they have to be cleaned? We have insane CaCO3 concentrations in the water. Wash clothes, and your jeans can stand on their own).
I've read all the comments and the main argument is that people will not want to work with Basic Income being provided. This comes from a basic lack of understanding how basic incomes work. They are intentionally very low. Imagine making in the bottom quartile. You have enough to eat something each day, you have something that shelters you from the environment, you can afford to shop a thrift stores and craigslist. However, you would want for more. New Apple stuff, disneyland tickets, a vacation.

There are 2 main veins of basic income that I've heard:
1. Basic income that distributes goods from automation (ie, robot economy) . Not really what's being discussed here.

2. A basic income that is enough to not die and not enough such that most people would be satiated. Those that are not satiated would be encouraged to work on something, both that others want and that they want to do. Jobs that people would love to do would pay very little, jobs that suck (something to do with poop, surely) would pay more, the market forces are still at play.

If #1 ever becomes real such that all human want is satiated (I do not believe in infinite demand for consumption) or
#2 pays too much, then yes it sounds like a scene from that movie WALL-E
The HGV pulls up to a traffic lighted junction. The driver is indicating to turn left. The traffic lights are currently red, and so the driver is stopped.

A cyclist undertakes the HGV - passes on the left. The cyclist is attempting to reach the cyclists junction box.

While making this manouver the traffic lights change from red to red-amber and then green. The HGV driver checks the mirrors but does not see the cyclist (who is in the HGV blindspot) and pulls off, turning left, crushing and killing the cyclist who is trapped between the HGV and the curb.

I've tried to word this neutrally. It's a tragic situation and there's learning for cyclists and HGV vehicles, and road designers here.

There are some SQL databases build on top of HBase. HBase and the whole Hadoop ecosystem is not what I'd call easy, but once you are familiar with it, scaling it is relatively easy (probably still not as easy as Cassandra, thanks to the fact that Cassandra always hashes things and does not allow sorted range scans).

I'm currently experimenting with Phoenix, because it's a relatively thin layer above HBase, but it doesn't provide many features that you expect in relational databases like transactions. SELECT support is quite complete, it can do JOINs, subqueries, etc.

I have recently discovered Trafodion which looks like a much more complete relational database, but at the expense of no longer being just a HBase client.

The local politicians in my city that lured the IOC here through bribes were all later parachuted into lucrative foreign service diplomatic posts and various IOC connected director positions after. That's the true legacy of the games, the politicians raise their profile, network with the world's elite and move into international politics while the rest of us pay for their promotions.

Having the winter olympics in Switzerland only would make sense, easy to secure, neutral country, no forced relocation of "undesireables" like when Beijing shipped every Mongolian migrant laborer out of the city, or when my government mass imprisoned as many homeless as they could by picking them all up for unpaid fines.

No country would have an edge with exclusive track access for months before allowing competitor teams in to practice either.
Close, I think that the premise the Bush administration used to obtain this information, "dragnet surveillance", was ruled illegal, which exposed the phone companies to lawsuits. Congress then retroactively indemnified them.

Oh, please. They could actually have published criteria, you know, stuff like "convicted of such and such", or "passport from Yemen, North Korea, etc". It's only "political correctness" of the Deep State kind that allows this sort of rubbish - too dangerous to fly, but not dangerous enough to arrest or charge? How does that happen?

Besides, if the TSA/DHS went with anti-politically correct criteria, like say, Arabic style names, or attending a mosque or wearing a turban, even a total idiot will be able to find a Terrorist Sympathizer who's white, female, got a German-sounding name, and convince them to carry more than 4 oz of liquid through the nudatron in their hollowed-out shoes. Even dumber people will figure out that it's obvious you can circumvent the stupid theatre that anti-PC criteria would cause.

I bet the truth is more like the incentives that DHS has. It's better to keep anyone even faintly seeming or associated or accused of "terrorism" or similar things on a watch list, because then, when something bad happens, they've "done what they can".
