comment Plotting in random color within axis environment
What is the smoothing function applied to the y-coordinates to get them to diverge from 0 as x increases and converge to 0 as x approaches 1?

comment What are the incompatibilities of pdftex, xetex and luatex?
Another difference is that they all use different graphics drivers. Sometimes the XeTeX driver clips included graphics more closely than the PDFTeX or LuaTeX (example). Is it worth expanding the answer to cover these differences?

comment A longer arrow in a diagram
That's a much neater way of doing it. Why isn't symbol= a standard part of tikz-cd? Perhaps it should be included in the next release.

comment Point of tangency and tangent line to a circle
@fpast, thanks for the comment, but 0.67 blue works fine for me; the space between a numeric and a colour-triple is entirely optional, and I prefer it for readability and to allow Vim syntax highlighting to work.
