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-s23/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
Since COVID is not going away any time soon, you can participate in the live lecture via Zoom. These Zoom meetings will not be recorded. 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).

One problem with such a Zoom setup is that audio/video equipment can malfunction (e.g., no sound in Zoom, camera is stuck pointing at the wall, etc.). If that happens, there is very little I can do and I must continue with the live lecture in classroom. Lecture videos from a previous semester is provided below so that you can still receive the same lecture material. Of course, it's best if you come to the live class when you can.

Tentative Slides
The following are tentative slides (in PDF format) for this semester.
Lecture Videos From A Previous Semester
(Please note that access to these videos is restricted.)

Lecture videos from a previous semester are provided here, in case that they can be helpful. You should get the lecture material by coming to class. In case you cannot make it to class, you can view these old lecture videos. I'm planning on covering exactly the same lecture slides as previous semesters. The main difference between the lecture videos and live classes is the old lecture videos are more condensed since I'm the only person doing the talking. Live lecutre pace should be slower.

Access to these old lecture videos are protected by an additional level of security measure. All videos here are on D2L, please enter your D2L user ID and password before accessing these videos. Please also see hints about using the D2L video viewer. You also need to enable 3rd party cookies in your browser.
