comment Open source alternative to Wolfram Alpha
I'm not looking for a computer algebra system in general, nor am I looking for the different ways I can solve this equation in each of them. I am asking if any of them are capable of doing the sort of liberal expression evaluation WolframAlpha is capable of.

Thank you! Seems obvious in retrospect, but then again, most things do.

comment How do I replace the last occurrence of a character in a string using sed?
For someone with only a basic understanding of regular expressions, this answers seems much more approachable. And who cares how many operations it takes, this is going to be instantaneous for all practical cases. So I would consider readability over some arbitrary rule to use as few operations as possible.

Not quite, but tex.stackexchange.com/questions/14901/… seems relevant. I'll take a look at that later.

Yes that is sort of what I had in mind. Although simply measure won't do, because how would it know when to place it above, below, left or right? Regardless, my tikz foo is too weak, hence this question.

But this is still a hardcoded number. If I were to scale the tikzpicture, the gap would change. On the contrary, the gap between the a and the rectangle stays the same, because of some magic in \node[below], I presume.
