Fall 2006
This schedule contains links to copies of last year's labs and lecture notes to give you an idea of what the future will bring. Because we will use xv6 instead v6 in lectures this year, the lecture notes will change considerably. We will update the lecture notes as the course progresses, and will announce release of the official versions of this year's labs on the course home page. (The bottom of this page shows the date of the last update.)
