Reflections on class today

- CS21A-B: **OK:** The mail system simulation mostly worked,

although it could still be tweaked slightly. His slides were okay,
too. **NI:** People need to be assigned reasons
to use the mail system simulation.

- CS21A-G: **OK:** My slides. Ended three minutes early, but

otherwise pretty okay. Got a few laughs. **NI:**
I could use a presentation chockful of filler material.

- CS110-A: **OK:** I prepared slides with the outline. **NI:** I ended

much too early. Should always have the next session ready, I
suppose. Also, SHOULD NOT WRITE ON BOARD WITH PERMANENT MARKER.

- CS139.3: **OK:** Again, brief overview with class outline and

policies. 3n+1 was a surprisingly enlightening problem. **NI:**
Brief primer on working with the online judge? Also, scared a number
of the students.
