@Trix If this answer is the solution, then mark it with the green checkmark that you find below the up- and downvote buttons.

comment Mathematica vs Python - how does it compare to Python's scientific computing suite?
Maybe this is a stupid question and until now, I had very little contact with python but which package of python lets you do analytical stuff like Integrate[Sqrt[x + Sqrt[x]], x]?

comment Floating highlighting bug
@Kuba Then there is more reason to report it. Maybe a two people bug is already the critical line where WRI starts investigating. Especially, since it happens on Windows (and not on Linux).

comment Floating highlighting bug
Awesome, just awesome. I highlighted your system specs a bit because this is vitally important to the question. Nevertheless, I would report it to WRI. Give a SystemInformation[] notebook for every computer where this happens and various screenshots. They can probably provide you with things you can try to narrow the bug down.

comment NotebookWrite a Cell with WholeCellGroupOpener option
Check Options[Cell] and try your example with all options that live in the context Gobal not System. As far as I can see, all options that are not in System will get $CellContext.

comment Place a small gap between axes and plot?
@Jens Especially, because one of the most useful functions for achieving this is broken since literally ever: AbsoluteOptions

comment Naming a pattern changes outcome in StringCases[]
And this is the correct answer. I'm not sure why I did not see this because in normal patterns like {x_Integer..} it is completely clear and I use it all of the time.

comment Speed up image coloring with ReplaceImageValue
"halirutan's solution is faster though"... this is because you don't try hard enough! Check this out: Import["http://goo.gl/NaH6rM"]["http://i.stack.imgur.com/VuZoL.png"] +1

comment When does Mathematica automatically use dispatch tables for function evaluation?
A quick check suggests that you should not forget to test Association which is made for dictionary-styled data. Please evaluate Import["http://goo.gl/NaH6rM"]["http://i.stack.imgur.com/6IwgG.png"] to see my small test. Btw, a dispatched table of rules is the slowest possibility there.

comment Speed up image coloring with ReplaceImageValue
@MilenkoRubin-Zuzic I just saw that you make a white border completely around each sub-image. I fixed the code and now it's even faster. I compared my output image with yours and it seems to be identical.
