comment Why ParallelEvaluate[x = 0; {$KernelID, Dynamic[x]}] returns {{1,x},{2,x}}?
@JasonB I am doing some computations in each kernel after this, and I want to monitor the value of x in each kernel during the computations.

@Szabolcs Yes it does. Thanks.

And what does Entropy do, exactly? That was my original question.

@Dr.belisarius If I want to calculate the entropy of a probability distribution, I have to generate a large sample from it first. Seems inefficient.

@Dr.belisarius Okay, that gives the number I want. Care to explain why?

comment Is the free Mathematica Trial Version a full version?
@MarcoB I think that reasoning could apply to all of Mathematica.SE. Any question here could be answered with higher authority by WRI. But I don't think that is the point. The point of a community like this is that we can all learn from our shared experience, which is much more efficient than if we all relied on direct replies from WRI.

Why the close vote? Please leave a comment. If this isn't on topic here, explain why. It is a question about Mathematica.

How do I revert this? If I want to have Print work again as usual in the current Mathematica session?

comment Bar legend coloring doesn't correspond to array plot coloring in the expected way
@rcollyer I have to agree with Edmund. Maybe it is not a bug, in the sense that this is how it is designed. But in that case, the design is questionable.

@rcollyer Agree (+1). I was about to accept this answer first.

Why the close vote? It may not be a bug, but the proper way to do this is not in the documentation. So this is a valid question.

This should be documented. It is not obvious that this is the right way to do it.

comment ReadList ignore comment lines?
@george2079 not a duplicate. The comments may be in the middle of the file.

comment ReadList ignore comment lines?
@JasonB Up to now I've done ReadList["file"], but maybe ReadList["file",types,n] is more convenient to ignore comments?

comment Average dataset with many repetitions?
@MikeHoneychurch Your comment also crashes my kernel. I have v10.3.0 on Linux.

comment Average dataset with many repetitions?
+1 Very nice and readable. And if I wanted the standard deviations of the results as well, I could use Values @ GroupBy[res, Query[{"p1", "p2"}], Merge@StandardDeviation]. Great!

comment Histogram of a very large dataset?
@JasonB The fact that the file is arranged in a table makes no difference. I just want the histogram of all the numbers in there. You can assume that the file holds a flattened list of numbers.

@JasonB It freezes during the Import command.

@march Good point.
