CS110: Principles of Computer Systems, Autumn 2021


  • Mon, Oct 11: Kudos on pressing through Assignment 2 and the filesystems assessment! I suspect this is the first time since the beginning of the quarter that you've not had some looking CS110 deadline, and that's gotta feel all kinds of awesome.
    • Assignment 2 is being graded this week, and we expect to have those back to you by Saturday at noon. We'll be grading the assessments after assign2 is graded, so expect those sometime early next week.
    • Assignment 3 goes out tomorrow around 5:00pm, and you'll have seven days to complete it. Remember that you're permitted to work with a programming partner for Assignments 3, 4, and 5, although you need to work with a different partner each time. Update: Assignment 3 handout is up right here, and I'm creating assign3 repos as I type this.
    • There is no lecture on Wednesday, October 11th, and my Wednesday office hours at moved to be at the same time on Friday for just this week. Discussion sections will still meet this week. We'll resume on Friday morning.
