SciPy 2015 is over, meaning that many non-participants like myself are now busy catching up with what happened by watching the videos. Today's dose for me was Jake VanderPlas' keynote entitled "State of the Tools". It's about the history, current state, and potential future of what is now generally known as the Scientific Python ecosystem: the large number of libraries and tools written in or for Python that scientists from many disciplines use to get their day-to-day computational work done.
