comment Joining and interpolating data points
It's been almost two years now, and I have to thank you again - because this answer has been very influential on what I've been using (Akima, and Steffen interpolations mostly). I wrote some C code for it that my employer is using now. I'll check out this newer method as well, thanks. :)

comment Bug? malloc munmap_chunk: Assertion failed
It is a bug, most definitely, but it may to do with memory fragmentation at your level of use. You'd probably have more luck talking to their support guys...

comment Bad numerical approximations
When typing reals backticks indicate precision. To be honest, I find them mostly useless.

comment Bad numerical approximations
There's a backtick there that shouldn't be. My guess is that you copy-pasted Sqrt[2] over the real, but the real has a trace backtick which you didn't see, or mind. Remove that backtick.

That should read D[vec, v[2]], surely...

comment How can Mathematica solve 7 equations and want to find 7 variables
There are too many errors in your input. If you are new to Mathematica, start with a simpler problem.

The new maps in Mathematica 10 look really cool. I think at least one of us botched something, because we get quite stark disagreement on wind direction. I'll check tomorrow where the wind actually blows. ;)

comment Finding Roots of Non-linear Systems: Rescaling polynomials
It's impossible to answer your question as it stands, however I could hint at the Method->... and WorkingPrecision->... options, that might get you sorted.
