Please note that all course materials available from this web site are debugged and updated all the time. All changes are noted, just below the download link. Also, all changes are marked red in pdf files. Please make a habit of checking for them semi-regularly. If changes are made due to observant students pointing out to me the need to make certain changes, then those students may get some benefit of getting a small "lift" at the end of the quarter. For instance, such changes were just made in LN 2. Basically, I record what I perceive as "good student deeds" in my "good deed file" (not only for debugging course materials but also for other things such as asking good questions, leading good discussions and helping other students) and will consult it for a possible bump-up when students' grades lie near borderline at the end of the quarter. – 8:06PM, Oct 06, 2012

(Do keep on voting here.) Please participate in the office hour poll, if you have not done so already. Optionally, if you let me know by email your availability on Monday, Thursday, and Friday, that may be helpful to me, too. This would be helpful especially if you are generally unavailable for my suggested office hours.
