They are - I worked as an intern at AT&T research one summer, and one of the other interns there was doing something with exactly this data. Of course, it was behind a few layers of security and could not leave the building, and even after all that the intern got only anonymized data, but it was definitely collected.
This was the beast that I had back then - beast as in huge and ugly, not beast as in awesome and powerful.
Gamers typically set their monitors to refresh at 125hz, if they can. I haven't been serious about gaming since the hey-day of CRTs, so I don't know what the current style is.
But back in the day, we'd get CRTs that could refresh at 125hz and set the game's refresh rate to match.
This seems like nonsense, but it's hard to prove it since you left it severely under-described.
In fact, there is a very famous algorithm that can be used with a quantum computer that factors integers in polynomial time. QP != NP.
Government shuts down one private website.
Because projecting one 2-D representation (the hand on the camera screen) onto another (the computer screen) is much easier than projecting one 2-D representation onto a 3-D representation.
That's because the government had it taken out.
Supposedly that is the job of congressmen and senators. They are elected by Joe Six Pack et al and are, as such, beholden to them.
Now, let's see how long I can keep a straight face.
It's a tendency that gets bred out of the population, by and large.
What is the difference between parallel universes existing, and reality acting as if they do?
Just because you don't care about birth order doesn't mean it is irrelevant to the likelihoods.
P(A|B)P(B) = P(B|A)P(A)
Optimization hinders evolution.
