Regarding the study they mention(the one that shows that children recognize Pokemon better than real animals and plants).

There is an important aspect of this finding that the article doesn't discuss. They don't link to the study, so I can't check for myself.

All the Pokemon names they mention are first generation. There are only 150 first generation Pokemon. It's a relatively small closed corpus. They also have bright colors and are very easy to distinguish. How many species of animals or plants does England have? Way more than 150, of course. How large was the sample from which the ones used in the study were chosen? It wouldn't surprise me if there were more than 150 relevant species that are needed to be knowledgeable in "nature stuff" in England.

Of course kids in urban environments don't know much about naming animal or plant species, that's just common sense. My beef with the study is that it doesn't seem to go beyond the common-sense notion because of the problems above... Knowing a small limited corpus of highly distinct entities will always be easier than knowing the very large (although still finite) corpus of animal and plant species that might be quite similar on the surface (e.g. cork oak vs holm oak, bee vs wasp, cat vs lynx, etc)
The 24-Hour Lunduke-a-thon
This is a sensitive and complex topic. I found it clear after reading the article how even people personally involved struggle to address it well. It’s unsettling to me how definite and confident some of the comments in this thread are. This will sound patronising, yet.. Please do think twice before posting - you’re talking about someone’s life.
Put ownership of productive goods and services in the hands of those who are actually creating those goods/performing those services. This would empower each person to push the investment of capital to what matters most to them--namely, themselves. When the consensus is formed, a lot more money will be devoted to maximizing human capital and a lot less toward the overhead (massive paychecks for a few, crazy cycles of bureaucracy) that are the hallmarks of today's economic goings-on.
No - it's specifically relating to him, not his knowledge.
As I said above, these signs do not show a literal maximum weight. They show a load class.
> With a few hundred mb file that sounds slow even today.

That depends upon how fast one can perform the memcopy of the entire buffer.

It has been said that latency amounts of 100ms are perceived as instantenous (https://www.pubnub.com/blog/2015-02-09-how-fast-is-realtime-...).

So if we take 100ms as our latency budget, then the max file size we can 'edit' with a straightforward memcopy (i.e., no gap buffer) becomes how much data the CPU can move in memory in 100ms.

With a modern CPU, moving on the order of 5-7 GiB/sec (http://jamesslocum.com/post/64209577678) a simplistic memcopy could handle editing the start of a 512MiB to 716MiB file and still feel 'instantaneous'.

With the much smaller file sizes of yesteryear (someone did mention Dos, many of the old Dos editors had a 64KiB max file size limit) in order for editing of a 64KiB file with a max latency of 100 ms required only that the CPU be capable of moving memory at a maximum of 640KiB/sec. On an 8088 IBM PC at 4.77Mhz with a 4 cycle latency per byte (https://trixter.oldskool.org/2013/01/10/optimizing-for-the-8...) the rep movsb instruction should achieve a maximum of 1164KiB/sec memory move speed. More than enough headroom to make editing a 64KiB max file appear to be instant, even using the basic memcopy method. Even if we assume 8 cycles per byte (4 to read, 4 to write) we still get 582KiB/sec of memcopy performance. Enough that editing would appear instant on all files less than 58KiB.

In most cases Oyster will only tell them where you entered the tube and where you exited. At a few exchange points you might tap out and in again but at most you will not. On a bus it will tell them where you go on but IIRC you don't tap on exit.

Tracking you by WiFi MAC address or similar techniques (I've heard of Bluetooth being used in some places) allows them to see where you went between entry and exit and how long you spent there. It will also allow them to track you outside the network when you are in range of one of their APs. The CityCOnnect WiFi in York tracks people around the city in this way, I'm sure other cities have similar arrangements.

> This is just a convenient data grab and profiteering.

I'm not sure about where direct profits might come from, but IIRC when York's city-wide WiFi started they were quite honest (or at least refreshing undeceptive) about it being a bit fo a data grab. From the council's point of view it helps them to know how people, especially visitors, navigate around the place. This can be a great help when planning changes to pedestrian signage & bus routes, and to reduce disruption when planning maintenance works on paths & roads. Of course the commercial partners will use the same data to assess advertising potentials and other such.
Random sampling is the foundation of statistical inference.

It works really well for estimating population statistics from sampling.

It works less well for predicting individual user behaviour (this tends to be where you need almost all the data rather than a sample).

Like, as your sample size decreases, your errors of estimation increase (1/sqrt(n)) so random sampling is normally the best way to approximate data (e.g. for real-time metrics).

You may wish to consider different sampling strategies, however. For some things, a persistent user (or other dimension of interest) makes lots of sense. For tracking service health, you probably want to sample on requests.

You may also wish to over-sample particular groups, if they are important to you (like maybe an F2P game would sample for most users, but store a larger proportion for paying users).

tl;dr random sampling is awesome, and should be used broadly.
Exactly. I spent a ton of my childhood outside but the animals I actually saw out there were pigeons and stray cats.

> This is just a convenient data grab and profiteering.

I know people working on this project, and that is absolutely not their motivation. They want to better understand the movement of people within the system, so they can design better stations, trains, and services.

The traditional way of understanding such passenger movements is by parking students with clipboards and people-counters all around stations, doing passenger interviews and such. This traditional methodology is not only hugely expensive, but the data it generates is spectacularly bad, and has lead to some incredibly poor planning at times.
Sounds like he is just saying movies today are held to a much lower standard.

The biggest successes of the last decade or more have been superhero movies that are basically just special effects extravaganzas.

There's nothing wrong with enjoying mindless action movies (I enjoy them myself) but let's not pretend that the current glut of original productions in favour of endless comic book adaptation sequels and bad remakes of foreign movies represents anything more than a lowering of standards and a lack of originality and creativity in Hollywood.

He would be right.

Turkey's GDP has been growing with a few setbacks steadily. This year alone the growth is 5%.

Turkey has been under a lot of stress for a very long time. Few countries could sustain growth under such circumstances and many could not especially after 2008 global economic crisis. On top of that on going conflicts by its borders, huge refugee influx, terrorist attacks, Gulenist instigated social riots (Gezi Park), and the worst is the coup attempt. I believe it is unfair to point any data without a mention of above.

And do not forget Turkish Lira's value before Erdogan's party came into scene. High inflation (> 50%) for decades, $1 worths over 1,000,000 Turkish Lira and always increasing. All these obscenities were fixed all the while huge infrastructure projects were completed.
I'd probably agree that seems to be how it's most widely shared. But note that Google did announce in Feb 2017 that they're changed their algorithm to combat fake news:

> Google announced changes to its search algorithm Tuesday that will combat the dissemination of "fake news" and conspiracy theories through new ways to report inaccurate information.

> The technology giant will change its search rankings to "help surface more authoritative pages and demote low-quality content," a company executive said in a blog post. This feature aims to prevent issues like the Holocaust denial results that Google saw in December — which placed an article from a neo-Nazi white supremacist website at the top of search results.

The legal and perception issues are a good point. Annoying, but I get it.

No, what you mean is that they can get away with it, because among their customer base, more people don't care that people that do.

Trying to get "off the grid" rarely is extreme to the point that you cut yourself from civilization completely. It's ok to have external help from time to time. It's just that your daily operation should not depends on it.
I take issue with the 100ms statement, but perhaps I'm missing something.

My hands automatically tend to play ahead of time when I play on a midi keyboard (piano piece) with anything more than 12ms.

Doesn't matter what I think I perceive, reality is my hands (muscle memory) intuitively perceive lag and begin to (measurably) hit notes just before the beat.

Likewise when I play a multiplayer (pvp) game, 100ms is considered even for the average gamer to be slow and annoying and is very much perceivable.

I like it no more than 25ms, and I have the luxury to get 7ms in best case scenario over fiber and ethernet. I can anticipate for the lag sure, but I feel it, which in this context is perceiving.

I am very confident I do not have to look at a gauge to perceive the lag, and can easily perceive it in a blind test around the 10 - 20ms response times.

I hit just one key and I notice if I lag or not. My ears are finetuned to expect the responding note to sound with at least 10ms accuracy within the resulting timeframe.
> I know people working on this project, and that is absolutely not their motivation.

It doesn't really matter the motivation if the system that gets built in the end has the same vulnerabilities and potential for abuse.

Attitudes change, and history shows us that governments have a bad track record for sticking to original motivations. Companies are even worse, once they realize the profit potential of something.

One candidate for useful work is TOR-supernode work. If the internet were to become distributed and fully encrypted you'd need a lot of bogus traffic and rerouting so the real traffic becomes invisible. There are many obvious problems with this, but in theory the more computational resources you put into a TOR-like network the more resilient and the more anonymous it becomes.
I do not think that he (or us here) questions the utility of names. Rather, the utility of knowing only a name and not much else. Knowing the names of a hundred mushrooms is less useful than knowing which of them you can eat.

Agreed. I’ve been trying bing as my default for two weeks now and it’s actually quite ok. Give it a shot; it has definitely improved. Enough for ~80% of searches.
I believe that's naive. There is always a non-zero chance that deploying new code will cause an issue that is not covered by your unit tests or integration tests.

Good testing methodology means adding to your tests when you find such a case, not promising that all possible cases are covered all the time, because that's unreasonable, and the assumption that there's no way it could break on deploy is the kind of hubris that leads to breakages when you deploy.
If you only wanted "highlight" animals and plants, you could probably get away with a list of 150 (or less - I'm struggling to think of 150 off the top of my head) but they definitely wouldn't be as easily distinguished as the Pokemon.

Found the study - they used 100 common species.

i’m surprised not a single interest group has hired a company like cambridge analytica to influence popular opinion of bitcoin, or a fake news network to aid in pushing the price higher, not that we would know about it, the big players in bitcoin would benefit from a scheme like this, it would be a small investment for greater returns, i am interested to see if it will ever reach a point where people will feel comfortable with it’s volatilty, but i strive to understand how the control of bitcoin network and its software is not in the hands of who contribute code, are we trusting a few now compared to a few banking institutions, is that the underlying tradeoff?
> A response time of 100ms is perceived as instantaneous.

please no :( my eyes hurt just from the thought of it. 10ms at most and I'm sure some people can perceive even faster stuff.
That's not what I mean.

I agree with your point, I'm just saying that people tend to use company services like they can count on them. The reality is that they have an agenda, and they will do whatever they can get away with to follow their agenda, not yours.

As such, and given our imperfect society, you should not expect anything from them and assume they will mess up.

I'm not trying to exonerate them from responsibilities, nor saying we should not act to improve things.

I just point out their nature and how we should take it in consideration in our decision process.

It is kind of interesting how these group of companies(Google, Facebook, Cloudflare) spin "Net Neutrality" when they have it their way, and then blackout sites when particular demographics demand it to be so. Most notably gab.ai.

I don't defend or care what gab.ai does, but the hypocrisy is maddening.

I think your example is analogous to what the article is referring to; children are excellent at learning the names of what they are exposed to.

"In Britain, the “roaming range” (the area within which children are permitted to play unsupervised) has shrunk by more than 90% in 40 years."

What does "..plenty of time outside.." mean here? Playing in the garden? I've no real exposure to what Australian wildlife is like, but it cant all be nocturnal.

The anxiety that (we) parents have of our children's welfare is the culture shift that is the root of these changes. Its far easier for me to keep an eye on my kids while they play in the garden, or reading about the outside whilst sitting at my feet.
Front end development, the barrier is it getting too big? (audio)
Cryptocurrencies aren't necessarily deflationary. Some aspects are quite inflationary, in fact. They can fork. They can have arbitrarily-imposed coin limits increased by changing a single line of code. Other aspects are deflationary, such as the ability for coins to be destroyed or lost forever. How these two forces are balanced against each other is up to the consensus stakeholders (miners) in each case. They should be expected to act in what they perceive to be their own best interests, which could be either deflationary or inflationary, in different scenarios. The interests in PoS and PoW systems could diverge significantly, as in a PoS system the miner's universal interest would presumably be to maximize the value of the currency, whereas in a PoW system the miner's interest would presumably be to maximize both the value of the currency they retained as well as the value of their real-world mining assets.
Yeesh, thanks for the downvotes on an actually measured result.

I'm trying this in Firefox nightly (stylo enabled, webrender not).

Even on an old phone over throttled internet, that page is faster than real HN for page transitions, but the same happens on 100Mbps WiFi with my Nexus 5X, or on LAN with my desktop.

In all cases, that site is significantly faster than real HN in loading and rendering (I can see the real HN's icon slowly load on every page refresh — that page doesn't do that).

If you get different results, you're probably using Chrome, which is over-aggressively caching.
I would suggest a lot of fake news is sparked by a headline and an article that goes largely unread.
Passenger movements within stations, and between stations where there are often many possible routes.
The morning paper had a post about it the other day[1], but I'm not sure if the solution is acceptable to the usual cryptocurrency crowd because it depends on running the useful code on a secure enclave (like Intel's SGX) to ensure single-threading and correct count of useful instructions that were executed. The miners are then rewarded according to number of useful instructions they executed. (The correctness of the instruction count and the work done can be validated cryptographically with SGX). I thought it was an interesting concept nonetheless.

Title on this referenced article is "Bill Gates thinks the 1% should foot the bill for renewable energy, and he's offering the first $2B." It does look to be spinning off the Atlantic 2015 interview.

The 1% headline is just a left-wing dog whistle. Gates said "private sector" and didn't make a divisive statement.

For those that the class-warfare-esque headline speaks to ("Oh yeah! Those 1% need to pay!"), the "1%" are the reason we have nice things - because they want them. Put everyone in equal misery and then lets see how clean the air and water is, how many technology and medical breakthroughs we get, and so on.
Firstly, you don't have to root an Android device you own in order to install software on it other than through the Google store. It's just a setting (off by default, I assume to create a slightly higher bar for novice users).

Secondly, unless I'm mistaken, the program you mention doesn't allow you to distribute your software to other "regular" iOS users.

This is very interesting. Do you know if they have any interesting misconceptions about those animals they know about but have never seen (assuming you yourself know enough about rabbits, badgers, hares and such to know that they are misconceptions)?

It's interesting when many people know about a certain phenomenon through media or things like cartoons, which obviously distort reality beyond any possibility of recognition.

The most amazing example I've ever seen is the one about bullfights. Apparently, many Americans know about bullfights from a single Bugs Bunny sketch, in which he is dressed as a Matador and kinda "dances" with the bull in the arena. This apparently made many people think that that's basically what happens in a bullfight. Then you get some nasty culture shock when people watch the real thing, as in this reddit thread (WARNING: video with blood and violence against animals, first in CGI then in real life): https://www.reddit.com/r/videos/comments/68i332/to_those_who...

The comments were really surprising to me. I would expect most people from outside of Spain, Latin America and Portugal not to know about bullfights, but I definitely didn't expect people to know about it from a cartoon and harbor so many misconceptions about what it really is!

Spoiler: in a bullfight, the matador does nasty things to the bull (like sticking short spears with hooks so that they don't come out when the bull moves), dodges the bull's charge while distracting it with a cape, and in the end he kills it with a sword through the back. If the killing blow fails to kill the bull, they kill the animal with a knife just below the brain. Also, Matador literally means killer in Spanish, because he kills the bull.
