comment Why does the documentation call functions “pure”?
@Nasser, I think your comment would make a good answer.

comment Raster to Image conversion problem
+1 A nice bit of detective work. I think you are correct about the optimisation. If you set SetSystemOptions["ImageProcessingOptions" -> {"Verbose" -> True}] you get some debug output referring to "fast conversion".

comment how to speedup subpixel registration
To extract the transformation directly from ImageAlign, use the secret option ImageAlign[i0, small, "FindGeometricTransformOutputQ" -> True]

comment FindFaces: how to improve the results of the face recognition feature
@user15961, it's very strange. I'm sorry but I have no clue what could be causing it! There should be no difference between using the Automatic option and explicitly specifying the same file.

@user15961, what does this give? Cases[DownValues @ Image`PatternRecognitionDump`ffOpenCV, _FileNameJoin, -1]

@user15961, I'm not sure. Does the file exist at that location?

comment OpenCL_result not the same as that in the example-Julia
I get the same problem. There is also an error: "OpenCLLink experienced an internal error." This is on Windows 7 with an Nvidia GTX 550Ti graphics card. The compilation goes okay so I suspect a driver bug or perhaps the GPU's double precision support isn't up to scratch.

comment Can Listplot output data to an image whilst leaving axes and labels as vectors?
The linked question deals with 3D graphics, but I think halirutan's solution should adapt easily to ListPlot

comment Label Markers On ListPlot
It looks like Labeled in the first example positions the labels to avoid collisions. I didn't know it did that.

comment Assign a randomly generated list to variable
The TracePrint image shows the problem very clearly. No idea why this happens - I suggest you (and @Naitree) report this to Wolfram as a bug.

@Helium, that's good to know. I hope you find it useful.

comment Creating time-lapse movies with Mathematica
@Helium, googling "missing shlwapi.h" suggests you might need to install/repair the Windows SDK. On my system shlwapi.h is present in both C:\Program Files (x86)\Windows Kits\8.0\Include\um and C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include. Alternatively you could try using the pre-built MathMF DLL.
