comment Gravatars/identicons with Mathematica
@Mr.Wizard The differences are also in the documentation for Hash in version 7 and 8. Same examples, different outputs.

@Mr.Wizard The discrepancy is there, on v8 I get d9c48b644b8cc89bbcd07ec7a54dafc9.

@Mr.Wizard On OsX you can get the hash by typing this in Terminal: echo -n "gmailuser+10511@gmail.com" |md5.

@Mr.Wizard I've tried several gmail addresses and they always matched. I'll try to see where the problem could be.

comment Visualizing the difference between two sequences (strings)
Your approach might encounter a problem in some cases, try to use text2 = StringReplace[text1, {"s" -> "ss"}] and see how your output looks like.

@AlexeiBoulbitch You might use one of the tools that are available online.

@AlexeiBoulbitch Might be that you need a specific file format (.ico, .icns,...)?

And, before exporting to png you can scale the image using ImageResize. For a 128x128 pixels icon: ImageResize[ExampleData[{"TestImage", "Lena"}], {128, 128}].

comment Combine multiple PDF files into one document
There are several problems with this solution: (a) the pdf is a single long page, (b) at the beginning and at the end the opening and closing brackets are printed, and (c) each segment has a comma printed on the right margin.

comment Why are my FrameTicks not working on ArrayPlot?
@TomWellington Your range is defined by the length of your array. If you plot Thread@{Range[0, 1, 0.001]} the range will be between 0 and 1000.

@kguler Probably a typo (.1 instead of 1), it should be PlotRange -> {All, All, {0, 1}}

@TomWellington Your plot didn't produce any either, so I was dealing with FrameTicks only.
