Ah, now I see the true genius behind it...

comment Simpler input for the new unit support
Neat trick (+1), but if it's only used with UnitConvert, wouldn't it be easier to just write a new myUnitConvert function instead and substitute it for UnitConvert? In other words, what's the advantage of withUnit here? I don't have version 9, so maybe I'm overlooking something. (BTW I definitely think online access shouldn't be needed for this).

comment Creating legends for plots with multiple lines?
@mincos and @de_wright Sorry I didn't have time to update this yet, but it looks like some improvements are actually coming in the next version of Mathematica that may make this post obsolete. Anyway, I'm currently looking into modifying legendMaker to keep track of relative sizing of plot markers better. The alignment of markers with lines is always a problem with the textual (Automatic) markers because character symbols can't be placed with perfect accuracy.

comment Square both sides of an equation?
You could also add Thread[(x + 1 == y^2 + 2)^2, Equal] which feels more natural if you want to go that route...

A related question you might find useful: Is it possible to have Mathematica move all terms to one side of an equation?

comment How do I plot the derivative of a set of experimental points?
In this answer to a related question I suggested to use DerivativeFilter for this purpose. That answer would apply here too (I guess the questions are somewhat different but I tried to make my earlier answer more general so that it now turns out to cover your case...)

comment Rasterizing a plot make axes ticks invisible
@DimG Thanks for the accept - as to the axis thickness, the problem seems to be that the thickness of axes and frames is by default given as AbsoluteThickness[x] and the latter isn't translated correctly in the Export. But this can be fixed by explicitly adding an option AxesStyle->Thickness[n] or FrameStyle->Thickness[n] to your plot. Here, Thickness is a relative quantity that you can calculate from n = x/w where w is the width of the plot. For some reason, these relative thickness specifications are translated correctly.

comment Why does OS X need permission to allow JLink connections each time it starts?
Just for reference, the same has cropped up on the mailing list, but nobody seems to know a solution. I also see this problem, but only on a desktop Mac at the office, not on my laptop. I included this link because in the future an answer may appear there...

@user1031565 For the last part of the question, you may be better off using spherical coordinates.
