\label{sec:next-steps}  The material for the lectures, including syllabus, notes, \ipython\ notebooks, pre-test, and quizzes, is currently stored in a private \verb|git| repository. At the end of the Spring 2015 semester, the notes and \ipython\ notebooks will be forked into a public \verb|GitHub| repository;  exams and solutions will remain in a private repository and will be  available on upon  request. This both archives the course materials and provides a platform for easy dissemination.  Based on our experience with this edition, we will expand the pre-test to include more problems on statistics.
