Our revisions to the course are thoroughly documented, so that future editions can take advantage of our efforts.  The material for the lectures, including syllabus, notes, \ipython\ notebooks, pre-test, and quizzes, is currently stored in a private \href{http://git-scm.com/}{git} repository. At the end of the Spring 2015 semester, the notes and \ipython\ notebooks will be forked into a public \href{https://github.com/}{GitHub} repository;  exams and solutions will remain in the private repository and will be available upon request. This ensures that the archived lecture materials can be easily disseminated. The laboratory material is currently archived on \href{https://www.dropbox.com}{Dropbox}, and \href{https://www.dropbox.com}{Dropbox}; it  is available upon request.
