Computer tools for astronomers
In 2013, 2014 and 2015, I offered the 3⨉3 hours workshop: Computer Tools For Astronomers, on Stockholm University.

I have put up passive HTML renditions of the IPython notebooks presented during the workshop, for those who just want to view the notebooks without running IPython:
