Emphasizing socialization is one of the big tools of highly-ranked education systems.

Students benefit from explaining it to others by forcing them to clarify and solidify their own mental models; the other kids understand their peers more quickly and when multiple mental models form, the students can explain it to each other for multiple perspectives.

If it's a powerful tool, teachers should use it. Understanding is more important than grades; too many variables affect grades to make them a great predictor.

Edit: Reminder that American education is often bullshit and leaves jaded students. Just because something is useful doesn't mean our teachers use it in a way such that it is useful.

I also recommend teaching somebody something and if possible taking a class with intelligent people that is out of your element. For me, a topology course with a focus on discussion was incredible.

> Arguably, Heller was decided wrongly

Let's keep in mind the text of the Constitution:

> [T]he right of the people to keep and bear Arms[] shall not be infringed.

The foundation of this discussion is simple: that right shall not be infringed. Courts through US history have respected its value and significance:

> In Nunn v. State, 1Ga. 243, 251 (1846), the Georgia Supreme Court construed the Second Amendment as protecting the “natural right of self-defence” and therefore struck down a ban on carrying pistols openly. Its opinion perfectly captured the way in which the operative clause of the Second Amendment furthers the purpose announced in the prefatory clause, in continuity with the English right:

> “The right of the whole people, old and young, men, women and boys, and not militia only, to keep and bear arms of every description, and not such merely as are used by the militia, shall not be infringed, curtailed, or broken in upon, in the smallest degree; and all this for the important end to be attained: the rearing up and qualifying a well-regulated militia, so vitally necessary to the security of a free State. Our opinion is, that any law which contravenes this right, State or Federal, is repugnant to the Constitution, and void [...]”

Any law which contravenes this right is repugnant to the Constitution and void. That's a pretty strong statement to make, and it has been reinforced on many occasions.

> In State v. Chandler, 5La. Ann. 489, 490 (1850), the Louisiana Supreme Court held that citizens had a right to carry arms openly: “This is the right guaranteed by the Constitution of the United States [...].”

So, why do you believe it was decided wrongly? It seems clear to me that the Second Amendment was intended to protect the individual right to bear arms, not just for military service but for self-defense. The right was seen as necessary for a free society, both in the sense of the strength to resist invasions as well as to resist tyranny of one's own government.

There was dissent in the Heller case, but not about whether the Second Amendment recognizes an individual right. Both of the dissenting votes recognized that it does.
my favorite thing about this is the apparent fact that someone typed "bush hid the facts" into a notepad document then saved it. "oh man, this is big... better write this down..."

> He wore a vest summer and winter, and never learned to bathe regularly.

I am curious as to why so many geeky/nerdy type guys express disinclination to daily bathing (myself included).

While regular bathing is beneficial to maintaining hygiene and health, too frequent bathing (especially when using cleansing products) can disrupt the skins natural sebum, pH & moisture control mechanism, dislodge the natural bacterial flora which may predispose the person to harmful infections. Many chemical products commonly used during bathing (soaps, shampoos, gels, disinfectants) are known to mess with the human immune & endocrine systems, a few may even be carcinogenic. Afflictions like eczema, asthma etc. are allegedly attributable to a heightened state of "hygiene" among modern humans - the immune system which keeps constant vigil against infections, is rendered "jobless" because the chemical disinfectants have done it's job, eventually attacks the body itself.

Spurred by the aggressive marketing from the personal cleansing products manufacturers, daily bathing has become a cultural phenomena in our society. Prime motivation for daily bathing seems to be grooming these days.

Anecdote does not equal evidence, but I've encountered many geeks who are inclined to hold off having a bath until it becomes necessary. I wonder why that is?

No because it is not going to make much difference.

Fully agreed on that one.

This software has a ton of bad use possibilities, I just threw out the first one that I could think of, there are a whole raft of others.

> Open sourcing computer vision projects? Publishing on github?

No, it's inevitable. But there is currently no framework on how to deal with these things. Just because you can doesn't always mean that you should. There are a ton of things I could do that are legal but that does not mean that all those things have a net-positive effect on the society we live in and I think that the ability to build these systems comes with some responsibility.

> Me? I'm 100% for publishing this(and similar) projects - because the tech is already out there and being used. Pretty much every towtruck and repo man has had this tech running for 5+ years, and almost nobody knows.

Yes, I have noticed that proponents of evolution frequently reply to people with "you don't understand the basics" and "look it up in the literature". So by your logic, they must be working from faith.

Or, alternative theory: the topic is actually complicated, they are tired of ignorant people acting like ignorance is just as good as knowledge, and they don't feel obliged to spoon-feed decades of complicated material to people who, by all evidence, have no interested in learning it because it would interfere with what their gut tells them on the topic.
> The gap in our training would then be apparent at that level because they'd be playing against kids who are learning enough chess theory, i.e endgame theory.

Openings are a vast area of theory as well.

I played competitive chess in my teens for a bit (my neighbor was insanely good at it and I got better just by being his punch bag) and I always refused to learn any theory. I think it's comparable to cheating on a test, it's supposed to be a game and a puzzle and I would feel the same if I learned how to solve a puzzle by memorizing solutions from a book.

You can extrapolate linearly such numbers, it makes absolutely no sense. This is not a math class, we are talking about clinical effects with actual thresholds.
If by geographically, you're counting North America, your contacts are lying to you. I can't speak for Europe, but I'd be shocked if what you said initially is true there.

The latter is still fine for an adult male over an hour or two, but you're moving the goal posts.
I mean, you could try looking literally anywhere.. This is a well known problem;

From 2014:

http://www.bloomberg.com/bw/articles/2014-02-28/rates-of-lun...

In 2002, for every 100,000 men living in Beijing, 49
had lung cancer. By 2010, that number had risen
more than 50 percent, to 75. Women in China are
less likely to smoke and so have lower rates of the
disease. But among those living in Beijing, a similar
sharp rise in lung cancer cases occurred over the
last decade. In 2002, for every 100,000 women
living in Beijing, 30 had lung cancer; by 2010, that
number had also risen more than 50 percent, to 46.

So the rate in the US is 60/100,000 -- As of 2010, in Beijing, the rate is closer to 121/100,000. Does a 100% increase in risk change your opinion of these 'marginal' deaths? For a population of 21M, this is equivalent to ~13,000 additional lung cancer deaths.

Yeah, we had openings, middle-game strategy, endgame, as well as tactics, in our roster.

I know there were Chess Opening Encyclopedias, someone once donated one to me, but we could never afford to buy much material as we were lacking in boards as a start. Our school never had enough to spend on chess, it was athletics, soccer and netball that were on the budget. I live in South Africa if it adds any context.

I once got suspended at high school for 'focusing too much on chess'. I happily obliged and told the principal that I'd stay at home and study on my own, within 2 days I was back at school, and continued with my chess :)

After reading the title, I too expected to find a peculiar story about a covert team made up of software developers and hospital bureaucrats kidnapping and torturing a brain surgeon (which would have been a fascinating article).

I really really like the type of Sci-Fi / Adventure Story where the protagonist engineers and builds their own world from scratch (or almost) - see My Side of the Mountain [1], The Game [2], [Conrad Stargard series][3], Swiss Family Robinson, Robinson Crusoe, etc, etc .

So I really liked the first book in the Safehold Series [4] and I put up with the atrocious names (Zhasphar Clyntyn?!?!?) and the insipid, trite and self-congratulatory characters, and even the lead mallet subtlety of religion.

But by God, the series has just worn me out. I was almost screaming at the last book.

This issue seems loaded because cognition is the way you win big now. Although NFL stars win big with pay, it's the Gates and the Zuckerburgs who loom high in our minds.

I've learned to ignore the issue (aside from its entertainment value) because there's still too much for me to optimize within my phenotypic range and local environment to make me better off – or at least, so I think. Either way there's much more to keep me busy than navel-gazing at cognitive-height so much.

On a related note: James Flynn of the Flynn Effect has noted many paradoxes within his infamous and eponymous result. I.Q. might not be improving so much. He anticipates explanations which synthesize nature and nurture but also look at the mind in terms of more basic cognitive operations and strategies. If I.Q. scores increasing reflect on the acquisition of useful, task-specific strategies, one might still be emulate the downward effect of a couple of I.Q. points which is at least something to be optimistic about.

I don't know of the specific tutorial you're mentioning, but a good way to avoid memorized opponents is to play the London System as white, and a kingside fianchetto system as black.

In both cases you can play the same moves against virtually any opening and get a solid middlegame position.

Stanford Uses Virtual Reality to Make Its Heisman Pitch for Christian McCaffrey
Hmm, I had a similar outlook (although with Magic rather than chess :P), but got over it. Learning theory isn't like looking at the solution for a puzzle, it's like learning specific problem-solving skills. It doesn't take the challenge away but rather enables you to play at a higher level which, with a decent game, is going to be deeper, more interesting and more challenging.

Now I think of learning enough theory to get to an intermediate level (at least) is more like a ticket to play the game at all: the game I play now is qualitatively different from the game I used to play and broadly better. To be sure, it was still fun when I was floundering around, but competitive play with a high-level mental framework (and yes, some specific information directly copied from others) leads to far higher replay value.

I'm sure chess is the same.

Cantennas are easy, and you should never underestimate the amount of technology people will throw at an attack. Consider, for example, the people that made ATM shims that captured the card data while recording the PIN being entered on the keypad.

A smartcard is fine - my argument is against RFID. A card that requires an electrical or inductive connection isn't going to leak everything over the radio.

My suggestion of "digital jewelry" is merely an example of how the form of the smartcard is flexible. Creativity in this area could allow for some easier to use devices, which could be important in places like hospitals.
