Your bitwise example reminds me of how much I dislike working with Haskell's Data.Bits: (x .&. y) + ((x `xor` y) `shiftR` 1)

Cute: It is possible to use anatomical digits to represent numerical digits[...] Also, 8 and 23 are really difficult for me (and the left hand equivalents).

They did try in HEVC! It was scrapped because it decreased the encoder performance and its benefits didn't show up in their primary test metric (PSNR).

The term DC is borrowed from electrical engineering. https://en.wikipedia.org/wiki/DC_bias explains: The term originated in electronics, where it refers to a direct current voltage, but the concept has been e

It looks like the method described in the article also provides a verified timestamp without the need for a (centralized) timestamp authority. I'd say that's a pretty important difference.

For switching tabs, there's also gt and gT. For buffers, I normally switch with :b or :e, since I often end up with too many buffers for next/previous to be practical.

The SE thing was someone claiming a company was doing homomorphic encryption when they really weren't. (Here's a link for others: http://crypto.stackexchange.com/questions/3645/how-is-cipher... )

You don't need to know much (if anything) about PDEs. If you've taken an undergrad class in classical mechanics, you'll do just fine. If you're interested specifically in game physics using Verlet integration, http://web.archive.org/web/20

I'm more likely to finish a few chapters of a textbook than a series of videos: 1. Videos are usually too long. There isn't a natural break to stop and try things out. (Udacity does a good job with this one.) 2. Information density isn't co

Computers are used in (some parts of) math for exploration, but not so much when it comes to conjectures and proofs. In fact, I would argue that making conjectures is a distinctly human activity: it requires you to decide if something is 'i

If you find this sort of thing interesting, you may enjoy A=B by Marko Petkovsek, Herbert Wilf, and Doron Zeilberger. (Wilf was mentioned in the article.) It's available for download at http://www.math.upenn.edu/~wilf/AeqB.html

Leaving it as a differential equation gives you some room to experiment more easily. For example, suppose you want to add a swimming mechanic to your game: you might end up with a completely different closed form solution, but if you left i
