I am a førsteamenuensis (UK: lecturer, US: assistant/associate professor) in the Department of Mathematics at the Norwegian University for Science and Technology. I work in both differential and algebraic topology, both of which require that I use some category theory from time to time. I am also extremely interested in how best to use technology to help us do mathematics, particularly in the purer ends of mathematics where the obvious computational uses are not so useful.

comment Reuse tikz picture in another tikz picture
Embedding pictures inside pictures is generally not a great idea in TikZ.

comment Reuse tikz picture in another tikz picture
Are you using the latest version of TikZ (3.0)? If do, this has a new way of being done.

comment Floating point and fixed point arithmetic in LaTeX3: Where documented? Safe to use?
What do you mean by that last parenthetical comment? I know that new stuff has been added to the fp library recently (inverse tan springs to mind).

comment What package allows Elvish in TeX?
Thanks for adding the details! Next time I want to get elvish script in one of my papers then I know what to do. I completely agree with the "something done for fun and beauty" - best of both worlds.

comment How to put arrows on boundary circles in the tqft package
The boundary circles are nodes in their own right so you can use the angle anchors to avoid doing the calculations. Thus \node at (a incoming 1.90) {$\wedge$}; \node at (a outgoing 1.90) {$\vee$}; would put them at the right places.

comment Dashed lines only for covered boundaries with TQFT
Are you using the latest version of TikZ (3.0), by the way? If so, I've rewritten the TQFT code to make use of the pic syntax that has now been introduced and with the rewrite I've added more styling options such as would fix this. It's ready for testing from bazaar.launchpad.net/~tex-sx/tex-sx/development/files (run tex on tqft-pic.dtx and look at tqft-pic_test.tex for examples) but I need to test it and rewrite the documentation before unleashing it on CTAN.
