comment Label rows and columns of an ArrayPlot?
Almost. Only one more thing. The column labels should be rotated, otherwise they get scrambled. How can I do that?

comment Community detection on weighted graphs?
I think this interpretation of EdgeWeights in FindGraphCommunities is inconsistent to that in WeightedAdjacencyGraph. In WeightedAdjacencyGraph a weight of Infinity means that the vertices are not linked, whereas in WeightedAdjacencyGraph it means that they are strongly connected!

comment Community detection on weighted graphs?
Two questions: EdgeWeights have to be between 0 and 1? Vertices connected with larger EdgeWeights are considered closer or farther (that is, larger EdgeWeights pull vertices to the same community or to distinct communities)?

comment Using a compiled function inside NIntegrate gives “CompiledFunction::cfsa” message
I am worried that this solution might affect the performance boost that Compile is supposed to give. I am referring to the _?NumericQ pattern matching. Isn't there a more direct solution? Perhaps in Math 10?

comment Detect Messages within an expression without losing the return value?
expr2 gets evaluated only once after expr1 has completed, if and only if expr1 generates one or more messages. expr2 doesn't need to know the specific messages generated by expr1 (those will get printed to $Messages, so I will see them there if I have to).

comment Detect Messages within an expression without losing the return value?
The interface I had in mind was something like withMessageDetection[expr1, expr2], which always returns the result of expr1, and evaluates expr2 (ignoring its return value, but Print inside expr2 still has effect) if and only if Messages are generated inside expr1.
