Lectures - CSCI 402, Spring 2025, All Sections
In the lecture slides and videos section below, I will post lecture slides and pre-recorded lecture videos before 6pm on the day before the live lecture. Within 24 hours after a live lecture is over, I will add the recording of the live lectures there as well. For a high-level preview of future lectures, please see the tentative slides section below. For a detailed breakdown of each lectures, please see the detailed schedule 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/cs402-s25/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
By default, live lectures will be recorded in Zoom (unless there are problems). 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 email 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 email 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 email account).
Information About Videos on D2L
Access to videos are protected by an additional level of security measure. All videos here are on D2L, please enter your D2L user ID and password. Please also see hints about using the D2L video viewer. You also need to enable 3rd party cookies in your browser.

Lecture Slides & Videos
