I work at the Korea Advanced Institute of Science and Technology (KAIST). I study combinatorics. I'm still relatively new to Sage, so I'm generally better at asking stupid questions and breaking stuff than I am at answering questions and fixing things...although I am working on implementing complete matchings for combinat, and I'd like to see the ability to output TikZ code for various Sage objects for which that would make sense.
I'm the main author of SageTeX, a LaTeX package that allows you to integrate Sage code into your documents. I am working on the next version and hope to have it out sometime this autumn.
I'll be giving some talks at Sage Days 9, and put my slides, etc, at /Days9Talks.
I wrote some notes on setting up a (hopefully) secure Sage virtual machine using Ubuntu JeOS: /JustEnoughSageServer. I'm also expanding the notebook() docstring at StartingTheNotebook; this will likely end up in the official documentation, I think.
