GIS programmer writing Python in Emacs

I've finally managed to get the slides on my site, so here you go! On an almost unrelated note, here's a tiny cute one-liner that I've used to create a zip of all the code used in slides:

grep "\\lstinputlisting" slides.tex | \
sed 's/.*{\(.*\)}.*/\1/' | \
zip -@ pycon2011-code.zip
