It turns out I didn't record today's (Monday, 23 January) class.  My apologies.  Most of the class was covered by the slideshows for Workbook Exercises 1.1 and 1.2 (linked on the Handouts and Notes page).  

The first quiz will be on parameter setting and will happen on either Wednesday or Friday, depending on how soon we get through the remaining exercise 1.2 stuff + the practice with parameter setting handout linked here.
