Announcements (Week of Apr. 17, 2017)

  1. Due next week:

    • Lab 8A submission: Mon, 24 Apr, by 10p.
    • Lab 8A check-off: Thu, 27 Apr, by 10p.
  2. The Quiz 2 Resubmit submissions have been graded for partial credit. Please see your gradesheet for details.

  3. As some of you have noticed, there was a bug in the code responsible for computing the number of late days for a delayed check-off, which caused some students' late day totals to be tallied incorrectly. We have fixed the computation, and the grade sheet entries have been updated. Since this change may impact some decisions you made based on the incorrectly reported late days, we've also increased the number of forgiven late days from 7 to 9.

    If you want to double-check our arithmetic, here’s the method for computing late days. In the following, a “check-off day” is a day when office hours were held. Days start and end at 10p, the time at which submissions and checkoffs are due.

    • the checkoff deadline is computed as three check-off days past the later of the due date and the day you submit.
    • for each full or partial day past the checkoff deadline, it only counts as a late day if it’s a check-off day.
    • the total number of late days for a lab (counting both submission and check-off) is capped at the number of final points you earned for the lab.

Announcements (Week of Feb. 6, 2017)

  1. We will be using Piazza for all course-related discussion this (announcements and questions) this spring. This is where to post your questions and get responses from the staff. We'll also post announcements, corrections, etc., to the forum.

  2. You are responsible for familiarizing yourself with all of the course information under the "Information" menu above, particularly those relating to grading and collaboration. If you have any questions about any of the course policies, please post a question on Piazza!

  3. An understanding of programming in Python is a necessary prerequisite to this course. 6.0001 or 6.S080+(6.01 or 6.S08) can serve as the prerequisite.

    If you have not met the prerequisite for this course but wish to take it nonetheless, we strongly recommend that you try Lab 0, a lab-like self-test that will help you determine if you have sufficient programming background to comfortably take 6.009.

  4. Submitting assignments to the online system requires that you have a 6.009 account. We've initialized the accounts from the Registrar's class list, so most of you should be all set. If you need an account, please send your Kerberos ID (i.e., Athena login name) to 6.009-www@mit.edu.
