0 hours 0 minutes spent this session 2017-01-06 After each work session, please update and commit this file with the amount of time you spent working, the date when you stopped, and any notes you wish to make for yourself. Every commit of this file constitutes a work log entry. Each entry should replace the previous one, so there will only be one session recorded at any particular version of this file. Do *not* change the format of the first two lines, as the course staff will use automated tools to track the amount of time students spend on each problem set. When working in a pair, update the log file for each student with the time that student spent working in the session. If a student was not present at a work session, do not update their work log.
