\section{Next steps}  \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| git  repository. At the end of the Spring 2015 semester, the notes and \ipython\ notebooks will be forked into a public \verb|GitHub| \href{https://github.com/}{GitHub}  repository; exams and solutions will remain in a private repository and will be available upon request.  This both archives the course materials and provides a platform for easy dissemination.
