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-s22/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!
 
Information About Live Lectures on Zoom
Live lectures will be recorded in Zoom. For serucity reasons, you must sign into your Zoom account using USC Shibboleth SSO (Single Sign-On). Please note that this is different from signing into your Zoom account using your USC e-mail address! To check if you signed in into Zoom correctly, start Zoom and click on Settings if you are on your phone. On top of the screen right next to your name, it should say LICENSED. (If you are using a browser, then you should click on Profile and look for your User Type.) If it doesn't say LICENSED (and says "Basic" instead), it means that you are signing into Zoom using your personal account. In that case, you should sign out (on your phone, click on Profile, scroll all the way down to the bottomm and click on Sign Out). Then sign in again. On the Sign In screen, don't enter your e-mail address there, but look for an SSO button instead. Click on the SSO button and enter "USC" as the company domain and it will take you to the familiar USC Shibboleth SSO screen where you need to provide your USC NetID and password (this is the same screen you get when you login to your USC e-mail account).

Tentative Slides
The following are tentative slides (in PDF format) for this semester.
Detailed Video Schedule (also subject to change without notice)
The number of minutes below are rough estimated lecture video minutes and they do not include lab video minutes. Also, slide numbers below refers to the slide numbers in the Tentative Slides section above and they are also estimates since I may add or delete slides.

Please note that we are covering exactly the same material as previous semesters. This means that we need to cover 28 80-minute lectures and 14 50-minute lab lectures. In previous semester, when certain lecture days fell on university holidays, extra lectures were added so that the exact material can be covered. For this semester, 1/17 is a university holiday. Therefore, the lecture that was supposed to be held on that day (i.e., Lecture 3) was moved to the next day (i.e., scheduled for 1/18 and the date is highlighted in bold below).
