comment Savitzky-Golay Filter to smooth noisy data
Please add an example how it should be applied to a data (as an interesting data I suggest IR spectrum of gaseous water). What is the meaning of the coefficients which SavitzkyGolay returns?

@rcollyer Probably instead of AbortKernels[] you meant CloseKernels[]...

comment Tidy form of numbers with errors using ScientificForm
(+1) Notes: 1) Probably it is better to not show the exponent when it is zero; 2) You should apply N to {b, err} in order to work with _?NumericQ correctly (Integer, Rational etc.).

comment Failure in integrating from an interpolating function!
All your observations are the expected and well-documented behavior (while may be not immediately obvious). For me the interesting observation was only the nested NIntegrate case which is identical to the nested Block case: citing the Documentation, "NIntegrate effectively uses Block to localize variables." The f[hello] case is just how the lexical scoping works.

comment Failure in integrating from an interpolating function!
It isn't surprising because Integrate does not have a Hold* attribute and f[hello] is evaluated before Integrate. So actually Integrate[f[hello], {hello, a, b}] is equivalent to Integrate[0.333333, {hello, a, b}].

Note that NIntegrate[f[hello], {hello, 1, 2}] also gives 0.333333: the outer integration range does not matter!

This answer contains important considerations on the practical use of FunctionInterpolation and comparison with other function interpolation methods.

comment Why doesn't Mathematica support Import for SWF files?
Googling for "swf2pdf" might help.
