For anyone wondering how the "capturing light in motion" works - the researchers use a very short pulse of light, so when playing back the footage in slow motion, you can see the light pulse moving through the scene. They're not directly ob

There are sort of two different definitions at work here - the semantic definition which is as you describe, and then there's the technical definition which has to do with the implementation. "Subtitles" on a DVD are basically a 4-colour (3

c is not affected by relativity. It is a constant. The speed that a specific photon travels at is affected by many things - the medium it's travelling through, for one - but that has no effect on c .

The OPERA experiment wasn't a race between neutrinos and photons going from one place to the other - the neutrinos travelled the measured distance between the two detection points faster than c .

No, everything PLoS ONE publishes is good because they reject everything that isn't good. The "less selective" bit manifests itself as a reduced average "impact"/"importance", rather than as a reduced average quality.

Really? The answer with the highest upvotes appears to be rotating words to "random" angles, and links to a post[1] which has minimal code for just doing that. [1]: http://tex.stackexchange.com/questions/9323/are-there-any-la...

The real problem with having a monopoly is that once you've got it, there's no incentive to keep having the "best product at the lowest price". Look at the wal-mart strategy if you want an example. While there's competition, prices are lo

Assuming this is an NP problem, then a nondeterministic turing machine is capable of solving it in polynomial time (by definition). So it stands to reason that a properly-constructed quantum computer (being an approximation of a nondetermin

So after you delete the last element, how do you get the new before-tail pointer? If you recalculate it right there, you've actually done nothing in terms of the algorithmic complexity. If you defer it either until it's needed or until you

Actually, that's not the problem :) The can't-modify-a-collection-while-enumerating-it issue only comes into play if you're actually using an enumerator (either directly, or as part of a foreach loop) - the code in the article uses a plain

Though you have to be careful with that, because the obvious code for removing from a collection in reverse: for(i = list.size; i >= 0; i--) list.removeAt(i); Is itself a schlemiel algorithm on any singly-linked list...

What if you go for a more SOC-like design and stick the memory in the processor tower itself? The major bottleneck there is really in talking to memory, and you could that eliminate that entirely.

Why can't you fork it without the very latest code? You have access to the code that ships, which is the requirement of viral open-source licenses. You don't have access to the "very latest code" for the Linux kernel either, that resides (i

Having a look at that paper, the actual rate at which it produces bits is very low - for 2.92μW, they're producing only 500 bits per second. For an embedded device that might be suitable, but for a consumer or server machine you need a much

Alternatively you could walk in as soon as boarding starts, sit down and start reading, and not have to worry about looking up every few minutes to see whether it's your turn to board yet.
