comment NIntegrate::inumri: error
There appear to be (at least) a couple of typos in your code (e.g., the assignment for t1 and the "=" sign at the end of the code. That said, it's going to be difficult for someone to help you figure out what's going on without additional information about what this code is intended to do.

comment How does Mathematica detect the number of cores in a system?
My pokey little MacBook with an Intel Core M has two cores, by the way.

comment How does Mathematica detect the number of cores in a system?
I have an iMac with what I believe is an Intel Core i7-2600 (3.4 GHz). According to the Intel spec sheet, this processor has 4 cores and 8 threads. $ProcessorCount yields 4.

comment HIghlight intersection of two disks
If you just want to show the three regions, then why not remove reg3 from your Graphics command? You then have a red circle, a green circle, and some other color showing the intersection.

Works for me (10.3.1.0, Mac OS X v10.11.2)

comment Producing a list
I don't think that's changed in v10 (in fact, I confirmed it). Did you Clear[x] before you ran your code in v10?

Is this not as simple as using Flatten?

comment Why is ListPlot so slow here?
@Mr.Wizard: I don't have v7 any longer, but here are my numbers on my pokey MacBook Air: v8 2.1 sec, v9 0.43 sec, v10 3.6 sec. I used lp=ListPlot[dat];//AbsoluteTiming since it appears RepeatedTiming wasn't available until v10 (?). Anyway, it looks like you're correct--this may not be v10-specific.

Has anyone looked more broadly at plotting speeds? Apparently StreamPlot is slower too: mathematica.stackexchange.com/questions/78938/…

What do you mean by "not working?"

comment Position from 3 dimensional acceleration data?
As @DanielLichtblau pointed out, it's not clear what problem you've identified. That said, what you're trying to do is tricky, at best. Since you're doubly integrating accelerometer data, biases become a major error source (the bias is the value that the sensor indicates when it's not accelerating). Furthermore, biases drift, so correcting for them is challenging. Add to that noise and other error sources, and you've got a tough problem. Finally, you need to correct for the rotational motion of the earth...

comment Switching the ordinate and abscissa causes problem in `ParametricPlot`
It worked because your list effectively requested two parametric plots (new[x] and x), though the second parametric plot was underspecified and thus ignored by MMA.
