I prefer this:
Hermitian: \bar{v} * w
Bilinear: v * w
over
Hermitian: v * w
Bilinear: ???
though tastes are different ;-)

I finally tagged and released sage-mode 0.8 and marked the trac ticket #13182
for review. I thought I had done this earlier, so please review it if you use
sage-mode. I also added one tiny feature—support for sagetex in org-mode
exporting to pdf, so please reinstall the spkg before reviewing.
Google just released course builder, a python+GAE framework to develop

that into a online course? The technology to host it doesn't really matter,
