realitygrill··on Brussels Rocked by Terrorist Attacks
Cycling appears to be about an order of magnitude (~10x) times more dangerous, per mile travelled, than driving.
realitygrill··on Ask HN: Who is hiring? (February 2016)
I appreciate your saying that you can't accommodate bootcamp grads or junior developers yet.
realitygrill··on MIT dean to start new university: “No majors, no lectures, no classrooms”
Dull people don't usually call themselves dull. "Reasonably intelligent" or "average" are more common.

Think, was there perhaps a strategic reason to paint himself so?

realitygrill··on Google achieves AI 'breakthrough' by beating Go champion
It's interesting that Lee's style is similar to Carlsen: Lee Sedol's dominating international performances were famous for shockingly aggressive risk-taking and fighting, contrary to the relatively risk-averse styles of most modern Go professionals.
realitygrill··on The concept of “learning styles” is one of the greatest neuroscience myths
Daniel Willingham, cognitive scientist, convinced me of this:

realitygrill··on How Poverty Changes Kids’ Brains
I'm not sure about growing up poor, but I'm pretty sure I've heard something about how a disproportional number of founders come from dysfunctional families. One even claimed that doing a startup felt natural to him, as the chaos of startup life was more similar to his upbringing. Apparently a regular job's stability made him uneasy.
realitygrill··on Ask HN: Who is hiring? (December 2015)
Damn, how do I find an opportunity like that? I'm near Ann Arbor, too!
realitygrill··on Aphantasia: A life without mental images
But this year scientists have described a condition, aphantasia, in which some people are unable to visualise mental images.

This year? Galton (famously) published on this in 1883!

realitygrill··on Can't fire a brilliant employee, but he is late every day
Have you tried shortening your circadian rhythm with light therapy? Mine's about 26.5 hours and it's been quite helpful, though I have to sit in front of this light for a little over 2 hours every morning.

realitygrill··on The media in Singapore: Zip It
What a show of recalcitrance. You could probably bring up this issue in conversation and use it as a free speech litmus test. I am reminded of this comment [http://lesswrong.com/lw/kat/the_benefits_of_closedmindedness...]:

2-26% of Americans thinks gay people should not be allowed to speak

3-36% of Americans think that atheists like me (& 79.2% of LW) are better seen than heard

7-49% think militarists should shut up

16-48% of Americans disagree with free speech for racists

16-75% claim Muslims should not be permitted to preach against America

realitygrill··on Ask HN: Who are your favorite poets?
Same, but I'm more partial to Pushkin :)
realitygrill··on Ask HN: Does anyone else value the comments more than the link?
I could see that perspective, but I prefer to exercise my judgment on the comments.

It's a compromise for time and also a small measure against tab-explosions.

realitygrill··on Ask HN: Does anyone else value the comments more than the link?
Yes, I also usually only read the comments. Only if I'm convinced (by the discussion) that the link is worthwhile, will I click on it.
realitygrill··on A Mathematician’s Lament (2002) [pdf]
Would you elaborate on how you think things should be taught? I fell off around the time of the US pre-calc curriculum, but later enjoyed learning basic calculus and basic abstract algebra, so I'm pretty curious.
realitygrill··on The Insanity Virus (2010)
It's within the capability of science to one day develop an anti-love potion. Want to fall out of love with someone? Drink the potion, or wear the headset.

Actually, I have semi-jokingly suggested that friends in unrequited love take a certain class of antidepressant for a while, since this is one of the side effects -- it has a pretty good chance of working. So it may be easier to accept, although this is just n=1. (On the other hand, nobody has actually taken this advice..)

realitygrill··on Optimal Light Exposure for Rapidly Correcting Circadian Misalignment
I've been meaning to ask if you've read up on chronotherapeutics; when I read the book (that I cited above, in top-level) a few months ago it seemed to explain why the melatonin procedure that MetaMed gave you worked - a full biological basis. I didn't follow that up, though, since I was trying to fix my own DSPS.
realitygrill··on Optimal Light Exposure for Rapidly Correcting Circadian Misalignment
Light therapy is the main thing (seems daylight simulation and negative ions may also work, but this is less researched). The melatonin option is indicated at the level of micrograms, and as far as I know is quite safe. I'm mostly drawing from gwern's analysis and the opinions of several doctors, though, for the safety profile: http://www.gwern.net/Melatonin

Care to share some references? It would be useful to add to the page above.

realitygrill··on Optimal Light Exposure for Rapidly Correcting Circadian Misalignment
Anyone with sleep problems owes it to themselves to read Chronotherapy by Terman and McMahan (2012).

Basically, for manipulating your circadian rhythm, light therapy is recommended as the first line of treatment (possibly supplemented with low-dose melatonin). The timing and intensity of light relative to when your internal clock thinks it is in the day determines the amount of slowing or lengthening of your cycle. So bright light during when your body thinks it is 'morning' will slow down the cycle, and bright light at 'night' will lengthen it. That's why many people use f.lux. But how much, how long?

Your cycle's natural free-running cycle length (without zeitgebers, or cues, to entrain it) appears to be determined by genetic factors. This is hard to measure without doing some tracking and, ideally, actually free-running. Pretty inconvenient.

This paper, which I look forward to reading in-depth, claims to have figured out optimal ways [took another look: general principles] of calculating the correct exposure and absence of light to allow for rapid recovery from jet lag. If true, it will probably make all light therapy much easier to do and calculate.

realitygrill··on New antibiotic kills off persistent infections
Wait, how did you figure this out? I worry about having some sort of chronic infection..
realitygrill··on Melatonin
Interesting. I'm not sure I've seen extended-release melatonin. IIRC melatonin does not help you stay asleep, so that would be fairly useless.

I recommend starting at the smallest dose you can find designed for sublingual (under-the-tongue dissolving) administration. 0.3mg to 1mg is a good range.

realitygrill··on Melatonin
Hey, at least you aren't taking ridiculous doses. I'm pretty cautious about such things so I prefer the research.
realitygrill··on Melatonin
I don't feel any physiological dependence, as I go on and off it with no consequences that I can detect (other than becoming more prone to slip off my sleep schedule). Generally I only take melatonin daily when I'm adjusting to a new timezone/schedule or have lapsed by purposely staying up. Otherwise I use it maybe twice a week, and have gone months without any.

When I don't take it my sleeping time seems to be a function of sleep hygiene.. Your melatonin production cycles are probably most strongly controlled by zeitgeber factors, like the mentioned blue light wavelengths. My insomnia used to be as bad as yours and now it's fairly normal for me to fall asleep at 1am, even using the computer. Once you get in a pattern, it has some persistence to it.

realitygrill··on Melatonin
I use melatonin regularly to regulate my sleep cycle. It's a very effective part of a regimen (sleep hygiene, f.lux, etc) that allows me to manage a nearly-decade long problem of insomnia.

However, from a psychological standpoint, it's a very good thing melatonin is so safe. Every single person I've ever recommended melatonin to, I've directed to this article and discussed it with them. Every single such person then went ahead to promptly forget the discussion, NOT read the article, and take mildly retarded doses. For example, "one (5mg) pill didn't work, so I took 8 more at 4am." Another uses it almost recreationally - large doses to intensify his dreams; pretty much zero attempt to use it to improve his sleep. I don't talk to people about melatonin anymore.

For a quicker idea of where melatonin sits vis-à-vis other sleep drugs (WARNING: Hilarious Ambien Walrus referenced): http://slatestarcodex.com/2013/09/28/sleep-now-by-prescripti...

realitygrill··on "I have come to find out what it's like to be dumb."
The book to read here is What Intelligence Tests Miss, by Keith Stanovich. In it he argues cogently for both the importance and validity of IQ and the limitation of its scope. Rationality is not a concept contrived by theologians! (I find this idea extremely funny.)

You are referring to Howard Gardner's popular idea of Multiple Intelligences, which has been roundly criticized for having pretty much zero support. To quote the book,

Consider a thought experiment. Imagine that someone objected to the emphasis given to horsepower (engine power) when evaluating automobiles. They feel that horsepower looms too large in people's thinking. In an attempt to deemphasize horsepower, they then being to term the other features of the car things like "braking horsepower" and "cornering horsepower" and "comfort horsepower". Would such a strategy make people less likely to look to engine power as an indicator of the "goodness" of a car? I think not. [...] Just as calling "all good car things" horsepower would emphasize horsepower, I would argue that calling "all good cognitive things" intelligence will contribute to the deification of MAMBIT [Mental Abilities Measured By Intelligence Tests].

realitygrill··on A Mathematician’s Lament (2002) [pdf]
"Music is a stupid way of art, usually for stupid people. If you are writing literature or poetry, then you should be an intellectual; as a really good musician, that's not a must." -Holger Czukay

So there is this idea of different arts being more or less accessible to the general population.

realitygrill··on The most interesting things I've learnt about learning
The short version I've heard is: "The mind is not a vessel to be filled, but a fire to be kindled." -Plutarch

But upon some research, the context of the quote is even more interesting:

"The correct analogy for the mind is not a vessel that needs filling, but wood that needs igniting — no more — and then it motivates one towards originality and instills the desire for truth. Suppose someone were to go and ask his neighbors for fire and find a substantial blaze there, and just stay there continually warming himself: that is no different from someone who goes to someone else to get to some of his rationality, and fails to realize that he ought to ignite his own flame, his own intellect, but is happy to sit entranced by the lecture, and the words trigger only associative thinking and bring, as it were, only a flush to his cheeks and a glow to his limbs; but he has not dispelled or dispersed, in the warm light of philosophy, the internal dank gloom of his mind."

realitygrill··on A Test to Measure How Rational You Really Are
Well, the people over at the Center for Applied Rationality have tried to work on something like this, if only to attempt to better measure the effects of their workshops. I suspect this is a very hard undertaking.
realitygrill··on Do Elite Colleges Discriminate Against Asians?
Allow me to posit that a primarily intrinsically-motivated Asian student dealing with high-pressure immigrant culture is in a particularly shitty situation:

1. Feels forced to spend the extra time - at diminishing returns - to do well at everything with a grade attached. This comes at the expense of passion-based activities, regarded as 'useless' or invalid as a 'line item for the resume'. (There is wide understanding that you need extracurriculars to look good. As pg says, these are mostly bogus.)

2. The pressure itself is killing your intrinsic motivation, which means the surviving applicants are primarily conformist types.

3. Even if you somehow make it through intact, colleges will assume the stereotype and view your application through those lenses.
