In today's class, some discussion about the computer algorithm has seeped in. In the process, the two things (binary search (or bisection search) and quick sort) were sort of mixed up. Please check "DF" above to see a cleaner discussion of this. In particular, Nathan's comment on the quick sort algorithm speed was correct! Sorry about any confusion that you might have had! – 12:22PM, Feb 01, 2013

An email message to everyone in class, with the subject line "OH, homework, and quiz," has been sent out, on 10:22 AM, Jan 13, Sunday. It is the first email message sent directly from my computer, using my personal grading software – this is the way that all emails will be sent from me from now on. It is crucial that you are able to receive my email messages. If you indicated your preferred email addres in the questionnaire, then you will be receiving my emails at that address. If you did not receive the above mentioned email message sent out this morning, then it indicates a serious problem! If this is the case, then you must email me! — Sam, 11:50AM, Jan 13, 2013

The office hour poll results shows that Tue 11-12, Wed 11-12, Fri 1-2 are the best solution (satisfying 85 students out of the total of 88 students who responded). These are my OHs (old ones are not valid). For today (Jan 15, Tuesday), my prior arrangment prevents me from having OH at 11. So, NO OH today from 11-12! Instead, I will be available from 3:30 to 4:30, today – 3:34AM, Jan 15, 2013
