Recursively applying the "pay attention to the two levels above you" rule gets us to "the CEO sets the corporate culture."

There's nothing here that couldn't have been done before the Internet; but the instant ubiquity of such well-written final words seems to increase the emotional immediacy of it, for me. I was taken aback.

If you go deep enough, shallow-water blackout can happen on the way back up. I don't know what could go wrong just doing laps a few feet below the surface, though, unless he simply stayed under until he passed out.

Just out of curiousity, what's the salary of a personal assistant who can both keep your schedule, and set up an EC2 instance?

It's disturbing how seldom local jurisdictions follow the MUTCD. Just in case one does, though, I'm sometimes tempted to pull over next to those black-hoses-across-the-roadway speed measurement devices and spoof a lot of extremely fast traf

The Democratic People's Republic of Korea has a lot of artillery aimed at population centers of the Republic of Korea. But most HN readers do not spend significant amounts of time in population centers of the Republic of Korea.

I find two-wheeled conveyances more conducive to sudden insight than either ambulatory or four-wheeled methods of locomotion. My guess is that the greater portion of conscious attention required enables more subconscious creativity.

I don't think you can get around the nightingale-ish expected value of this strategy, no matter how you adjust the stakes and number of bets.

Obviously, they didn't try to patent the Chinese Remainder Theorem, or any other previously existing mathematical algorithm. But, as the top-level comment and the original post point out, > ...any method of manipulating information (i.e

The experience which is validated by many independent tests is the feeling of tapping into something truer and deeper. I don't think the GP is questioning the feeling, just the actual truer, deeperness of it.

Assuming such beings work on the same physics we do, they need massive amounts of energy to run a galactic civilization; and they have the same sources available that we do: Stars; and for extra credit black holes. Putting a dyson sphere ar

The reason it's "liar's poker," not "outright fraud," is that if someone calls your bluff, you lose that hand. The successful traders were just good or lucky enough to be able to bluff the entire market.

When I think of Hungarian problem solving I think of Polya's renowned book on proof heuristics, "How to Solve It"[1]. How accurate is that impression? [1] http://www.math.utah.edu/~pa/math/polya.html

Producing a good "creative work" is a useful enough signal that it's not a practice likely to die out: http://sarkology.wordpress.com/2011/04/11/why-creative-domai...

In 99.9% of things someone might be asked to explain, it's noncontroversial that at the bottom level it all runs on physics. csomar is extending that well-warranted assumption to one of the places it's sometimes contested.

I'm saying "lift is just Newton's third law" is approximately as descriptive as "the mind is just the interaction of weighted electrochemical links between neurons." The word "just" covers a lot of detail that can make the short explanation

The movement of a fluid according to Newton's laws is described by the Navier-Stokes Equations, which have no closed-form solution[1]. So, if your intuition gives you a picture of air moving downward from a wing, that's great. But if it f
