You don't have to go to the absurd "cheater gene" degree. Note this is not at all scientific, but rather trying to point out how easy some small genetic things might push society and culture in particular directions.

Suppose instead that a few traits like:
- Social Intelligence
- Impulse Control
- Desire for Retribution

have normal distribution with slightly different peaks in different populations.

A population with high social intelligence and low desire for revenge might tolerate more cheating(since people only cheat when they can get away with it) than one with low impulse control and high desire for revenge, where cheating might spark a shootout.

You probably don't have to move those distributions much to start seeing pretty large changes in things like mass shooting demographics, or who cheats.

Slightly different requirements.. X-15 was single seat, no provision for sight seeing, trained test pilots that could handle high G forces, etc..

Also, X-15 had much more tolerance for failure, frankly. When you're doing something for the first time with military test pilots, you can be 95% reliable. Virgin has to be nearly 100%, and that last 5% is a bitch.
So, why have 2 leaderboards? Or the private one has limited visibility by contestant?

(there seems to be simple ways for kaggle to solve this: put a delay on the score generation, limit number of submissions, limit precision of scores on the public leaderboard)
Three weeks ago I reverse-engineered my garage door opener wireless protocol. I probed the remote's PCB with a Saleae logic analyzer and found it was a 12-bit code ASK-modulated at 390 MHz with bits encoded as sequences of 10 kHz and 20 kHz pulses. I bought a $13 spare remote to hack it and control the RF transmitter section from my computer through an FT232 sending the ASK signal. I just cut off the digital signal trace going from the MCU to the RF transmitter and hooked it to the FT232. I built a brute-forcer and it works quite well. I do not have my notes at the moment, but IIRC one code takes 25.6 ms to be sent. And my manufacturer (Genie) seems to require the code to be transmitted 4 times consecutively to open the door, that's 102.4 ms. Multiplied by 4096 combinations, this gave me a brute-forcing time of 7 minutes.

I had tried Samy's exact attack to reduce the brute-forcing time but it did not work at the time because I tried it before I discovered the code had to be sent 4 times consecutively (5 times makes it more reliable due to RF interferences). So I am not surprised to see Genie absent from the list of models Samy found vulnerable.

But I should try to find out the longest period of time during which these 4 repetitions of the code need to be sent. Maybe it does not have to be perfectly consecutive, but it could be 4 codes received within an interval of 200 ms or 1000 ms. If so it might still be possible to build a modified De Bruijn sequence that repeats codes 4 times while being only 4 times longer.

By the way it is very surprising a description of the 12-bit Genie protocol does not appear to exist online. These remotes are so easy to reverse engineer, so common (Genie is in the top 3 or top 4 most common openers), and so old (the protocol has existed since 1985), you would think there would be information about it online, but nope.

PS: I wonder if there could be commercial interest in cryptographically secure garage door openers? A $0.50 ARM Cortex-M0 MCU is all you need to implement a HOTP based on HMAC-SHA1. Then a simple learning/pairing system writing the key in EEPROM can even sustain the battery being removed from the remote. But there is probably no interest... which is why most remotes are insecure even the "rolling code" ones.

(Edited to clarify some tech details.)
The 500 calorie number is a little sketchy. For it to hold true, here are some questions:

1. How accurately do we know how many calories are needed for maintenance? I would imagine this is highly variable, unless there is evidence to show it is not. People's activity can be quite different day to day. Also is there evidence that metabolism occurs at a consistent rate? If all these add up to an error that is an order of magnitude less than 500, only then can we reliably use the number 500.

2. There is some new research [1] that shows that we may have to rethink the calorie-labels based on how foods are digested. For example cooked food are sometimes digested more completely than raw food, leading to a net intake of more calories.

This is my greatest fear. This is the one thing that can paralyze me late at night when my mind wanders and wonders about what can go wrong in regards to my two daughters.
a month ago i was walking up the street and saw a drunk man collapsed, unconscious next to a set of bins, people walking past him, some stepping over his prone form.

i stopped to help him, no-one else seemed to be. no doubt in large part in aversion to having to deal with a rough looking drunk.

shortly after i'd tried to rouse him and started to call an ambulance, a girl came over to see if everything was ok. she told me that she'd previously walked past him and wanted to do something, but had been scared to in case he was unpredictable, because of the state that he was in (more than likely booze+drugs). to give you some sense, i'm 6' 2 and built like a bus. i dont think twice about intervening in situations, because i never feel unsafe doing so. unfortunately, not everyone feels as safe as i do, and that's not to say that something bad couldn't still happen to me.

i've seen enough situations like this, drunks lying prone in a state, couples having arguments that devolve into fisticuffs, horrible slow motion accidents, to think that these situations fall roughly into

im too scared to help

i dont want the trouble (someone else will sort it out)

i literally dont give a damn

i think on the whole, most do give a damn, but i think they'd be more likely to stop to help with an accident then they would a homeless person in a bad state.

one time i kind of regret trying to help someone was an elderly man who i saw in distress trying to get home. he was walking along, but the further he got down the road, the harder it became for him to walk, he was so obviously having trouble i went up to him and asked him if he needed help. i ended up chaperoning him all the way to his house, which was around the corner, up a hill. of course he had to go and collapse half way up the hill from exhaustion. at this point i thought, fuck this, and called an ambulance.

thankfully the old man finally managed to get home eventually. it turned out he'd sneaked out for an amble to the shops, according to his carer, even though he couldn't really walk well enough to do so. him collapsing on me as i manhandled him to the ground is one of the scariest things that's ever happened to me. i thought that by helping him i'd inadvertently participated in giving the guy a heat attack or something.
After losing a parent >10 years ago: at first there's a gaping hole in the world, but the world knits itself back together and in its new configuration you find happiness like anyone else. But you know it's a diminished world. It's missing something wonderful, which most people don't even know about.

It's not something I dwell on, but the grief still comes out now and then. Just my experience, and I don't presume to know what it's like losing a child or spouse.
Have you watched the movie "Eagle Eye"? How about "WarGames: The Dead Code"? If not, please do. Both, in their own way, have some interesting points regarding the risks involved in using A.I. in warfare, as well as the reduction of complex social interactions to mere graph theory and statistics.

Exactly what did this workers do wrong? As was noted in the article, a number of them did such a good job that they were expecting a raise.

> “The first 30 days was all capturing what I did,” said the American in his 40s, who worked 10 years at Disney. “The next 30 days, they worked side by side with me, and the last 30 days, they took over my job completely.” To receive his severance bonus, he said, “I had to make sure they were doing my job correctly.”

> In late November, this former employee received his annual performance review, which he provided to The New York Times. His supervisor, who was not aware the man was scheduled for layoff, wrote that because of his superior skills and “outstanding” work, he had saved the company thousands of dollars. The supervisor added that he was looking forward to another highly productive year of having the employee on the team.

> The employee got a raise. His severance pay had to be recalculated to include it.

My use of the word "hyperinflation" was hyperbole referring to a commonly held view that unprecedented money printing by central banks could lead an inflationary nightmare, often asserted by doomer goldbugs. The polar opposite view seems to be the Keynesian theologians who believe that any level of money printing & gov spending are awesome++ and point to measures like the CPI that have not really moved even as the monetary base in the US has quadrupled since the financial crisis.

What I meant with my comment is that perhaps the goldbugs were right about the problem but wrong about the effects and that the orthodoxy is wrong that everything is ok++ and there is nothing to worry about.

Here's some dots to connect if you want to deduce my line of thought:

Swiss culture is still very insular. As an example of language and imagery that would be seen as quite racist in the US or the rest of Europe, take a look at this poster from the SVP/UDC party, currently the strongest party in the Swiss federal parliament: http://www.20min.ch/schweiz/news/story/22226627

The slogan means "no special rights for foreigners", in protest of a practice that allows foreign residents in switzerland to sign petitions to open up a non-binding resolution in local city councils.

I don't think I've seen such baldly racist imagery from a US political party in my lifetime - it looks like WW2 propoganda.

Impossible to do that. Maybe most potential commentators are so appalled by the aggressive and judgmental tone of the article/comments that they had to withdraw from the discussion. Let's not argue from speculation.

I recall that Bordes and Tideman were a good source on this issue; I believe the (relevant) paper is "Independence of Irrelevant Alternatives in the Theory of Voting." -- The upshot is that the condition known as IIA (I think it is sometimes known as Sen's condition-alpha, and the condition that many people harp on, including Michael Dummett) is in fact a stronger condition than is needed for the result; roughly, that instead of needed a condition about consistency among selections over possible ballots (like: if y were selected in ballot [xyz], y should be selected among yz on ballot [yz]..) we simply need a requirement that the selection only involves information on the ballots (and that the relative rankings of candidates not on the ballot are irrelevant to the selection).
To a developer there are few things more annoying than having to speak to someone to get concrete pricing information, n.b. how each plan is marked as "from $xx/m".

Wow, way to miss the point. The "profiles of foreign leaders", according to the OP, comes from a Pentagon sanctioned study. The Pentagon is funded by American tax dollars. More importantly, these reports are unclassified and so there's no reason they shouldn't be in the public record. Even more importantly, someone at the Pentagon thought such a subject was important enough to waste money studying. Even even more importantly, that means there's a good chance that someone else at the Pentagon or State Dept. will use such information in some oblique way when making a policy decision.

But yes, let's all go back to watching the Lifetime Channel and not think about government details unless it is really sexy sounding and can fit in an Upworthy headline.

Tell HN: Things I Learned about Credit Bureaus This Week
Last week, 1 or more parties hacked my Equifax account, set up an account at TransUnion, and ran up charges on a cloned credit card in Brazil. To resolve this, I’ve interacted with the FTC, police, card issuer, and credit bureaus. Here’s what I learned about the credit bureaus:

1. Equifax has no escalation path for security breaches on weekends.
Even if a breach potentially affects millions of accounts, there is no way to report it until Monday.

2. TransUnion has no ability to investigate hacks or security breaches.
They can only generate a reference number for the customer to file a police report with. (Note that their top product category is Credit Management & Protection.)

3. TransUnion and Equifax do not cooperate on investigations.
Despite evidence that suggests the same hacker was at work, neither credit union indicated any interest in even talking with the other.

4. If your TransUnion account is hacked, you will lose online access for life.
You will never be able to download your credit report from TransUnion again, and can only get it via mail. For life.

5. Experian displays your mother’s maiden name on your profile page.
There is no way to hide this, obscure your mother’s maiden name, or select a different security question.

6. Experian agents cannot view support ticket numbers or track tickets.
Only a supervisor can access ticket numbers. Of course, that means you need to talk to a supervisor…

7. Equifax and Experian are extremely reluctant to generate a ticket or escalate to a supervisor.
At Equifax, I requested to speak to a supervisor 7 times. At Experian, the agent awkwardly tried to resolve a CloudFlare server error by asking if I was using Internet Explorer. It felt endemic. I did not sense this at TransUnion.

This experience has eroded my naive confidence in the consumer credit system. The burden for prevention, monitoring, and remediation is borne almost entirely by the customer. This doesn’t seem right.

That's true. You probably can get out. Until the security team catches you, which they really, really can do. Trust me, I do it for a living. And then you're in trouble for violating the terms of your employment, and then HR gets involved, and then you are fired.

Like I said, if you're going to work in security, you're going to have to consider a lot more than can it be done. Corporate security is more closely tied to HR and the business than it is IT. You can't break the rules just because it's technically possible. It would be your job to find the people who are doing exactly that and report them to HR.

My dad owns a mid-size landscaping company in a medium-sized city in the Midwest. Until the Great Recession hit, he'd hire around a hundred of laborers from Mexico and Latin America on H2-A visas every year. He could only do so after proving that they could not hire enough Americans at a reasonable wage (obviously, the meaning of "reasonable" is hotly debated, but at the time, it meant slightly higher than minimum wage). I've never understood why similar restrictions aren't put on H1-B visas.
