So there were about 160 people, I asked how many of them can do programming, I think roughly 30 people raised hands and then I asked how many of them know Python and about the same amount of people raised hands, which was very interesting to me. I run over all the cells in the worksheet, everything went smoothly. Except for one cell, that holded the long polynomial expression, didn't resize well and I couldn't make it resize, this was annoying. But otherwise the notebook worked pretty well. Previously, when giving some demo/tutorials about sympy, I prepared a .py file and copy&pasted things into the terminal, but from now on I'll be using the web notebook --- it's way more convenient, as I have better granularity in determining if some cell goes wrong (the .py file just raises an exception and ends, while in the notebook just this one cell fails), I like that I can use the text cells (headings/titles) so that the worksheet has some structure etc. I *love* that I can output html, so my (actually Fredrik's:) demo code that produces the integrals/derivatives table just works in the notebook and it looked really nice in Firefox, using the unicode pretty printing. I need to figure out how to use the jsmath more easily, and also the pretty printing in sympy is tailored to 80 characters terminal width, but the notebook trims it earlier, so it looks ugly if the expression is long. But overall, I am sold for the web notebook/online lab, couple years ago I was very skeptical, as I really love just a terminal. But for these kinds of presentations, the notebook is better than a terminal.
