This course currently has 75 students.

CS 343 satisfies one of the systems breadth, tech elective, or project requirements within the Computer Science major. It can also be taken for credit within the CE major.


We will use Canvas to report grades, and for access to Zoom and Zoom Recordings, but for little else. For critical announcements, we will send email to the addresses that CAESAR maintains.

For discussion, we will use Piazza. Directing your questions to Piazza will likely produce the fastest response, and everyone else in the class will also benefit. Piazza is configured to allow anonymous posting.

Accounts, Remote Access, Getting Started with Unix

  • You will have a Linux account on the Wilkinson lab.
  • You will also have a Linux account on private servers we have set up. These accounts will be discussed in class, discussion, and on Piazza.
  • It is possible to set up your own machine to do the labs. More info is on Campuswire.
  • All lab handouts and handins will be handled via GitHub Classroom. You should be sure to sign up for a GitHub account if you don't already have one. The details of using GitHub Classroom will be discussed in class, discussion, and on Piazza.
