(author here, sorry I didn't see this earlier) One of the principles we tried hard to follow is that after building the indices, the query times should be proportional to the resolution of the plots you're generating. So the diffe

(Author here, sorry I didn't catch this earlier) The 3.5 minutes is the preprocessing time (think of it as index-building time). After the index is built, the goal is to be able to generate outputs at a time bounded by (up to a poly-

You can write composable WebGL, but it takes more work. Here's my Loop-Blinn example: http://cscheid.github.io/lux/demos/loopblinn/loopblinn.html The bits that do Loop-Blinn are here, https://

That turns out to be exactly what I did, but that type of opportunity is now much rarer than it was even 10 years ago. MSR is the stalwart "you-can-publish-here" industrial research lab, and look at what happened to MSR SV -- to s

Myer and Sutherland wrote a classic 1968 paper on what they came to call the Wheel of Reincarnation: simple displays accrue progressively more complexity until someone comes along and throws the whole thing away with a new, clean, design. T

The graph you linked to. I'm comparing the 1984 numbers to latest available, since 1984 is what the linked piece talks about (and which I mentioned in the original comment) > drop off was nearly identical for men > women did seem

Read the graph again. The dropoff for women is much larger. $ python >>> 20000.0 / 17000.0 1.1764705882352942 >>> 12500.0 / 7000.0 1.7857142857142858 CS enrollment for women in 1984 was 78% larger than in 1996; F

David Deutsch also proposed a similar resolution for closed timelike curves, which say that if you have a probability distribution of the present, all that's necessary is that when you travel back in time, you get the same probability

That's very much not what quantum computing is about, sorry. It does not do exponential parallelism by trying many things at once. What it does do is create exponentially many paths, while some of which interfere with one another des

This is really nice. Minor nit #1: https://www.dropbox.com/s/2meqa8hhen9ztba/Screenshot%202014-... Seems like the graph visualization is sticking to the wrong coordinates (dragging it to the left doesn't help

Wait: the entire point of Bayes's idea was that under very sensible and straightforward rules, "plausibilities" behave exactly like probabilities. So why multiply concepts? What is the difference, in your proposal, between &q

The paper is from 2005, so it might be worth saying that on the submission title. And it's also worth mentioning that because Gelman and Shalizi have recently written a really nice paper about the philosophy of Bayes: http:/&#x2F

Heh, this is far from the worst problems in this dataset. Wait until you find the clusters of lat-long points coordinates that are off by 1 degree in either direction (or 0.1 degrees) Then there are some pickups clustered around weird areas

A fast sorting algorithm in Haskell degrades gracefully to a (faster) selection algorithm when you don't ask for the whole thing. In other words, "sort lst" gives you a sorted list, but "take 5 (sort lst)" gives you

Now someone needs to start a project to find a large, documented subset for which ANGLE(ToGL(x)) = x so we can all get rid of this historical two-standards-that-do-exactly-the-same-thing nonsense.

I found the Acela north of New York (NY-Boston) to be great, but south of New York (NY-DC) my experience was a bone-rattling ride from hell. It was shaking so bad it threw my laptop off the table not once, but twice.
