Ha, I guess we just see the world differently. What you're describing sounds exactly like the dismissiveness I'm talking about. I hope your life is full of "personal side quests" pursuing questions that appeal to your pa

You're saying you knew the thing you wrote for n=3 specifically was wrong and just wanted someone else to confirm? I don't know man, I'm not really buying it. I think you did the classic dismissive nerd thing[1] and hedged it

You might want to check that your proposed solution works at all before suggesting the problem is trivial. What's the probability that the first die goes first with your numbers? You also can't generally "and so on" cons

I believe they are mixing it up with The Guns of August (published in 1962, also by Tuchman), which JFK was fond of and supposedly drew on during the Cuban missile crisis.

This is nonsense, at least in part because it's mixing two different ideas. The notion that the image "looks exactly the same as how it originally appeared" is only true when one of your eyes is positioned exactly where the c

Another aspect of the solution that makes it rather abstract is it effectively assumes we know nothing about the distribution of the number of days. Paying at 1/2 will be optimal if it ends before you buy, very bad (3x optimal) if it e

If it wasn't clear, their statements are all true when the events follow a poisson distribution/have exponentially distributed waiting times.

The main image is all at the same 90x level, and those buttons just zoom in (more or less) all the way on the points, while the "140x" are separate scan patches at higher magnification (though the real point is they have 3D/h

That isn't at all what the central limit theorem says. The whole point is it holds independent of the actual shape of distribution of the population. You could use the same argument to say social security numbers are normally distribut

The nice thing about deciding on a distance metric is that it gives you both a path (geodesics) and the speed, and if you trust your distance metric it should be perceptually constant velocity. I agree it's non-euclidean, I think the h

Actually playing around with it the behavior was very different from what I expected - there was much more zooming. Turns out I missed some parts of the zoom code: Their zoom actually is my "y" rather than a scale factor, so the

I think you can reasonably think about the flight path by modeling the movement on the hyperbolic upper half plane (x would be the position along the linear path between endpoints, y the side length of the viewport). I considered two metric

You're misreading the solution, the first part reads n=1, a trivial special case, not n congruent to 1 mod 4. The statement doesn't hold for e.g. n=5. Taking m=2 gives the permutation (1 2 4 3), which is odd, and thus cannot have

Wikipedia (citing a book on archive.org but no page number) [1] claims the largest order of an element of the Rubik's cube group is only 1260, so the simple repetition strategy would have to have a repeated unit way too long to be prac

The example is poorly chosen in terms of practicality for this reason, but otherwise, no, this is a poor summary that misses something interesting. The memory layout isn't changing in the faster versions, and there are no additional ca

I was surprised the article didn't add another couple of sentences explaining the finite field construction of the Hamming code. It seems like the important property of β is generating the finite field of size 8, so that its powers fro

Many of the contributions are others reversing and implementing a new game on top of the existing API, so the really labor-intensive per-game work is still spread out reasonably well.

The Pokemon Snap behavior is a mixture of handwritten code and parsing of the game's AI code. It was originally written in a very structured way that makes it easier than having to fully emulate. More involved interactions are missing

The justification on the main page doesn't inspire confidence: > IQ test reports costs 19.99 due to increased costs associated with collection, updation and normalization of data.
