  • Some of you have been asking about the 6.02 grading policy. There's no specific grade distribution that we target -- more A's is fine with us.

    Historically 6.02 has given 40%-45% A's and approximately the same number of B's. If you earn 90% or more of the total points, you'll get an A. If you earn 80% or more of the total points, you'll get a B. But the borderlines are usually a bit lower than 90% and 80% -- I suspect they will be this semester too.

  • Small correction to the PS6_5.py template: if you have already downloaded PS6_5.py, please delete the line "self.p = self.network.pmax" in __init__ method of WinCSMANode (line 21 of the file). p and pmax aren't used in implementing contention windows. Sorry for the confusion... The copy of PS6_5.py on the website has been updated to reflect this change.

Week of March 14, 2011

  • This week's to-do list:
    • Wed: PSet #5 due
    • Thu, Fri: Lab checkoff with your interviewer

  • Next week's to-do list:
    • Spring Break!

  • Here's some important information as you tackle Python Task #2 on PSet #5:

    The lecture slides suggest limiting the received voltages to the [0,1] range before computing the square of the Euclidean distance in the implementation of soft branch metrics.

    This is the theoretically correct thing to do (since, eg, voltages above 1V don't qualify as suspect 1's). But if you include something like max(0.0,min(1.0,received[i])) in your code, it won't pass the tests in PS5_2.py where the expected value was calculated by simply using (received[i]-expected[i])**2.

    So for this task, do *not* limit the received voltages to the range [0,1].

  • Quiz 1: average = 83.68, stddev=14.61, histogram, solutions PDF.

    You can now pick up your Quiz 1 from Cree Bruins at 32-G784A.

    If you think a question has been mis-graded, please bring your quiz and couple-sentence description of the grading error to your recitation instructor by Tuesday, March 15. Sorry, we won't accept regrade requests for Q1 after that date.

  • The first meeting of 6.02 will be at 2p in room 34-101 on Wednesday, 2/2. Consult the Course Calendar for a detailed schedule of lectures, recitations, labs and quizzes. Recitation meetings start Thursday, 2/3.

  • Recitation assignments: As a starting point, please attend the section assigned to you by the Registrar. NOTE: due to staffing changes, THERE IS ONLY ONE 1p SECTION. If you were assigned a 1p section and can make one of the other section times (10a, 11a, 12n, 2p), that would help keep the 1p section from overcrowding. Thanks in advance for any scheduling flexibility you may have.

  • Please take a moment to read the Course Info page which describes course mechanics and policies.

  • PSet #1 has been posted. Note the Wednesday deadline. The 6.02 lab (38-530) will be staffed starting next week -- please see the Lab Hours page for a detailed schedule.
