comment OpenCLLink eating up all host memory
@user2224780, if you're sure you are freeing all the memory you've allocated then either my fix is breaking something as you suggested, or there is another bug in OpenCLLink. Sorry I can't be more help! Maybe Wolfram technical support can help...

comment OpenCLLink eating up all host memory
@user2224780, that's a shame, as I said it has been working for me with CUDALink. I'm not sure if that message refers to host or device memory - what does the mathkernel memory usage look like when you get that error?

comment FindFaces: how to improve the results of the face recognition feature
@lalmei, no idea at all! Probably best to start at the OpenCV website (linked in this answer) or google "OpenCV beard detection" or similar.

comment How to write efficient code? How to make this example run faster?
Since xx and yy are listable, just using xx[lval, phival] will probably be the fastest method.

comment Reconciling results from Fourier with those form FourierTransform
Have you looked at the definition of Fourier and FourierTransform in the documentation? It is given in the first bullet point under Details and Options for both functions.

comment How to calcuate the sum of 1/x, where x is an integer not containing the digit 9 and 10,000,000 ≤ x ≤ 88,888,888
@gpap, all those extra multiplications make a difference! That pure function is called nearly 79 million times...

@Mr.Wizard, I tried Outer originally but kept getting an out of memory crash. The problem was using / for the division, as soon as I put Divide in instead it worked.

comment Why does a variable become real when using the second argument of Dynamic?
FYI you can Spelunk the definitions of BoxForm`RemapVariable and BoxForm`RemapValue, they are indeed kernel functions which do just what you guessed.
