This kind of spatial scan statistics is really easy to misuse without careful multiple-comparison corrections. Would they have reported a 52% effect? a 51% effect? What about 1.4 inch bands? or 1.2 inch bands? That "remarkably thin&q

Agreed! What I'm trying to get at is that there's two ways you can think of academia: 1) roughly the set of people in traditional institutions, and 2) a basically unorganized set of people that happen to come together through work

John Baez has had an interesting series of posts about this on G+, but IIRC the gist of it is that even though both Grigori Perelman and Yitang Zhang were somewhat outside the mainstream of academia, their work was not. Both of them built

It's not cutting off. It's replacing many long-range effects with a single one weighted more (and done it carefully so that the floating-point error is literally smaller than you could tell). There's even better methods that

For one, because if someone does find a hole that gives them access to Github data, they'll have all password attempts, which would include typos of the real password. Which is a terrible, terrible thing to store in a hard drive (see

I recently scored a copy of Maxwell's Demon, a book containing a collection of (among others) Landauer and Bennett's papers. As I was skimming them, I couldn't help but think that if there is a correspondence between heat and

The important thing in this demo is that his code reduces to arcball-like rotation in the globe projection, but works on arbitrary map projections. Notice how the interaction works for Eisenlohr's projection in the same way as the glob

The number your comparison is missing, and one that happens to be crucial to both business and technical differences, is that you should be looking at tweet impressions , not tweets.

Seems like a rare case where using this technique gives you much more entropy from a good passphrase than from a good password (although I guess over the shoulder watching is similar)

We've been working on an iPython-notebook-like system for R, called RCloud: http://github.com/cscheid/rcloud . It's not nearly as full-featured as you want, and still very heavily in development. Still, it doe

Similarly, I once heard a story that http://en.wikipedia.org/wiki/David_(Michelangelo) has a bigger head than usual because people would be looking at it from a funny perspective, and foreshortening would make it look

So I looked it up, and it's actually on the seminal 1948 paper: http://cm.bell-labs.com/cm/ms/what/shannonday/shannon1948.pd... It turns out that I either hallucinated (incorrectly, perhaps) one sid

Reminds me an argument about crossword puzzles I think comes from Shannon. It goes like this: in a sufficiently "fault-tolerant" language (ie with low per-character information content, which sorta gives large Hamming distance), c

The slickest part of that demo is the continuous level-of-detail rendering. That's extremely helpful when scaling up to large maps.

It's more than assignments looking normal. "await x" is better since it's an expression and not a statement. That is, "await x" will be a placeholder for a value (after the appropriate CPS, of course), while

If you drop stage 1 in Earth's gravity well instead of Mars's.. yes it does :) Edit: as mikeash points out in the reply, I'm plain wrong. You could use multi-stages to accomodate different gravities when launching Earth-Mars-

"Willpower" ( http://www.amazon.com/Willpower-Rediscovering-Greatest-Human... ) calls what you're describing "precommitment", and claims it does work consistently well.

Well, you don't know that. It could have been 0.16% instead of 1.6%. All we know is the math doesn't work.

(Replying here because your other comment is too deep) I believe you have it right. The NSA document gets it wrong by one digit (page 6): http://i2.cdn.turner.com/cnn/2013/images/08/09/2013_08_09_th.

This is very cool! A very nice feature to have would be to run topic modeling (say, your run-of-the-mill LDA) on the comments, and then colormap the nodes as to preserve the distances in the comment topic vector. This way you'd be able
