If you can get your hands on an emulator, you owe it to yourself to try "The Castle" and "Castle Excellent", two of the best puzzle games ever created. But do play them on an MSX; the NES version is nowhere near as good.

But look at the variance on those distributions. "Late 30s" is a poor description. How about "half of the winners are between 28 and 45"? Not so exciting then, I would guess. Better yet: look at distribution of "age

I think OP might have been thinking of s/efficient/dense Antimatter is certainly the densest way we know to store energy, which is great when it works. But unfortunately, it's also the densest way we know to store energy. Whi

Double-plus nitpick: in Vect, VxW can be seen as both a product (which is usually called cartesian product) and a co-product (which is usually called direct sum). So, I guess I would not say "rather than" but "in addition to&

First hit on google for "Haskell Wiki Monoid" was this: http://www.haskell.org/haskellwiki/Monoid Lots of examples there, including a post by Dan Piponi that says, right at the beginning, "In Haskell, a

What about a group? Is that combinable too? Monoid is short, precise, and googlable. Which also happens to be the case with group, monad, functor, etc. Why invent new vocabulary? Have you noticed how little sense the words "class"

by cscheid 13y ago
But "Appendable" is a terrible way to describe what a monoid is. Some of the really cool tricks in the way abstractions in Haskell match mathematical notions come from extending the abstractions beyond what you would expect. For e

You're right, it is :) The version with online demos uses latitude/longitude for the spatial dimension, but a new version we're working on (under the master branch on github) allows arbitrary x,y addresses. With that, we&#x27

Heh, I had a conversation a few weeks ago with Jeff Heer, coauthor of a very similar paper where we talked about how to make this stuff work with hexes. I think it can be done, but the hierarchical part is a pain, and I'll need more th

It's open source ( http://github.com/laurolins/nanocube ), so one could certainly try that. With that said, it is currently an in-memory store with no disk backing, so it would be a significant amount of work to get

Memory usage gets worse as the number of dimensions increases (because there's more ways in which to build summaries), and also as the number of unique keys increases (because there's more of different things to store). The main a

(Hey, I'm a big fan of your WebGL work!) This is really not about interpolation or mipmapping; it's about creating a data structure that allows you to quickly answer queries with which to build visualizations. For example, you mig

You don't need to drive out all honest mining. All you need is not to have to pay for any costs. The issue he's pointing out is that the rational, amoral actor will have to decide between a saturated market of ASICs with extre

Sean Carroll talks a bit about this kind of problem here, (albeit when discussing the distinction between "coordinate space" and "momentum space") where we perceive the world in one way, but a lot of physics seems gears

In a tangential note, if P=NP, a sufficiently carefully crafted algorithm very much like that suffices to solve any NP complete problem in polynomial time! (Of course the constants are ridiculously, absurdly large) http://lucatre

Wait, no, LU decomposition is not stable unless you're doing pivoting. And if you're doing pivoting, then it very much stops looking like an "exact formula", because it'll get filled up by ifs and variable renamin

Sorry, but if that were the case, then just showing the list of pages and their locations would get 100% of them, with 0% probability of being "by chance". Then, you say "that's a complicated rule: no one can memorize th
