comment How to make dynamic input fields work with drag & drop
@m_goldberg, I can't argue with the "risky" comment, you do have to be careful not to drop your selection in the wrong place or it will simply vanish. I did try turning it off for a while, but in the end decided that the convenience outweighed the risk.

@Mr.Wizard, version 9 on windows 7. Pretty sure it worked with version 7 on XP too. You do have to have drag and drop editing enabled in preferences.

comment Is there a way to parallelize the convolution component of EdgeDetect?
EdgeDetect uses ListConvolve internally, which uses FFTs where possible, and Mathematica uses the Intel MKL library for FFTs, which is already multithreaded. So you might not get as much performance increase from parallelisation as you expect.

comment How to extract Audio Record data form Sound[SystemDialogInput[“RecordSound”] ?
Try adding Method -> "Queued" to the Button. The evaluation is probably timing out on the preemptive link.

comment How can I create jpeg images of a given file size?
For the file size you might consider fine tweaking by changing the maximum image value instead of the dimensions. E.g. a random image with a maximum of 0.1 will compress more than one with a maximum of 1.0

To get the watermark at the right size without changing the aspect ratio try this: ImageCrop[Rasterize[string, RasterSize -> dim, ImageSize -> {dim}], {dim, dim}, Padding -> White]

comment Manipulate executes expressions multiple times
Please expand on what you mean by "TrackedSymbols does not seem to work". Here if I add TrackedSymbols :> {i} then there is only one Print per change of i.

comment Guidelines on giving readable names to variables
FYI in version 9 a\[Dash]b is interpreted as Times[a,b,\[Dash]], no idea why this has changed.

comment How to get and set default font parameters for Plot, ListPlot, LogPlot, etc.?
InputForm is very useful too for examining graphics expressions, it's easier to read than FullForm.

comment Implementing an algorithm for finding the largest circle that contains a single point in a set (and no other point)
I don't know if this helps, but there is a Graphics`Mesh`Voronoi which is about 3 orders of magnitude faster than VoronoiDiagram. It returns only the coordinates of the cell vertices.
