Thankfully I managed to get back to PyConAU this year, and again it was an absolutely fantastic conference. The organising committee really have done an amazing job. If you're looking for a detailed break-down of highlights from the conference, I recommend you check out Graeme Cross's post on his blog Curious Venn. One thing that surprised (and pleased) me was a profound sense of social responsibility that many people in the Python community are feeling.
This year I spoke on Managing scientific simulations with Python with RQ (Redis Queue). The talk was recorded, and you can find it (and the rest of the PyConAU talks) at PyVideo, or on the PyConAU YouTube channel
