Within 24 hours after a lecture is over, I will post the lecture slides I used in the section below.
For a preview of future lectures, please see the tentative slides section below.
To download all the PDF files below in one command (so you can study for exams),
do the following inside a terminal in Ubuntu 16.04:
wget -r -l 1 --user=USERID --password=PASSWORD http://merlot.usc.edu/cs353-s20/lectures.html
where USERID and PASSWORD are the user ID and password used to access protected content from our class web site.
But please note that the lecture slides can change at any time without notice. Therefore, it's a good idea to re-run the above command often
to synchroniza your copy with the server!
(Please note that access to lecture notes is restricted.)
