Oh, and Re@x=Re[x] is just the real part of x.

comment Integral evalutation
Not sure about a reference, but numerical approximations can fail, if, for example, the numerical values involved are very small. In that case the floating point reals in the computer cannot properly store those values. One could try to rescale the problem. Another problem can appear if one has highly oscillating integrals. Think of a, say, a sinus function with very high frequency. One then has lots of parts that cancel, but the numerical approximation only evaluates some of those. Depending on what points exactly are used for the approximation the resulting integral can be large or small.

comment Exporting Code to pdf
Actually, it seems that my Mathematica 9 does not use the Printout environment in this case and thus changes to this environment have no effect. CurrentValue[PrintingStyleEnvironment] gives Printout though. Very strange.

comment Auto line breaks in workbench
Hmm, so it seems Workbench has no line wrap. And installing the word-wrap plugin for various versions of eclipse does not seem to work with workbench.

comment Strange ParallelMap behavior
Hmm, but the documentation of DistributeDefinitions states that "Higher-level parallel commands automatically distribute definitions needed". So why would I need this? Bug? And how would I know when to use DistributeDefinitions?
