comment Solving parametric equations by eliminating the common variable
Yup, my thoughts exactly. The edit changes the original use case somewhat.

A wild guess: the interpolation function is not properly distributed.

comment Using an ellipse as a threshold for Nearest function
Hmm, what about a tilted ellipse? I guess one would multiply the data by the inverse matrix representing the rotation and scaling...

comment Ticks in ListLogPlot using LevelScheme
You'll get better answers if you post a small self contained snippet of code demonstrating your problem.

comment Why does $Failed have attribute HoldAll?
@LeonidShifrin Hehe, I remember that a lot of your posts end with "I will change/improve/revisit this soon":) That's why I agree with beli 100%. I would also recommend to post the comment as an answer. The hypothetical more knowledgable people can either post their own answer or improve your own.

Hmm, why the close votes?

comment NMinimize seems to call function with the same values multiple times
Hmm, I wonder why manual memonization does not help. ClearAll@f; f[x_?NumericQ] := (f[x] = (Print[N[x, 10]]; x^2)); NMinimize[f[x], x, Method -> "RandomSearch"]. So I guess f gets converted/compiled under the hood...

comment Import Large Excel File
I usually export to mx.gz (not that this format is not necessary compatible among versions and platforms, but it's an order of magnitude faster to work with). You might also take a look at HDF5.

@Alberto And the speed difference between the two is absolutely negligible for most applications.

comment How does the speed of WriteString compare to other languages?
I think absolute timing would be more appropriate here. I don't think I/O is counted under CPU time.

comment Problem with Creating Mathematica Package
Why the Unprotect and ClearAll? (Usage symbols, or more exactly, creating the symbols in mypackage` instead of Private was the problem).

Did you take a look here? docs.nvidia.com/cuda/…. If I remember correctly, not all version of drivers are cuda compatible..

comment How to manipulate some list-plot in Mathematica
You should learn to format your code when asking Q, post self contained snippets and not use single capital letters in MMA.
