Frontdesk Queueing Problems

The course staff is aware of a queueing problem with compression submissions on Frontdesk. We are working to resolve this issue. We apologize for the inconvenience.

Daegun's office hour moved this week.

My office hour tomorrow (10/12) is moved to Thursday from 7 to 8 at West wing cluster. Sorry for the inconvenience -- starting mini 2, there won't be not many changes.

Jeff's office hours 10/12

I'm moving my office hours this week to Monday 10/12, 4:30pm-5:30pm, GHC 4122. Sorry for all the schedule changes I've made this semester; there should be more consistency in the 2nd half of the semester.

Compression lab is now due 10/17

The due date for Compression has been moved from 10/15 11:59 PM to 10/17 11:59 PM. This also means that you may turn in the assignment by 10/18 11:59 PM at the cost of 1 late day, and by 10/19 11:59 PM at the cost of 2 late days.

Also, in preparation for the lab, I recommend the following PDF, prepared by Owen Durni, that shows all of the compressions and transformations that you will be implementing. Note also that you will be implementing the Burrows-Wheeler transformation slightly differently than what was presented in recitation.

Midterm Stats

We are done grading. The mean, median, and st. dev were: 51, 51, and 12, respectively (out of 80 points).

Last minute reminder

Last minute reminder: there's an office hour right before the midterm! Come with last minute question at the last minute! I'll be at Wean 8th floor couches from 11 am or somewhat earlier. Daegun

Adam's Office Hours Moved (this week only)

I am holding my office hours this week on Sunday, October 4th in GHC 4122 at 2pm, instead of on Wednesday. This is mostly to be of more help for studying for the exam!
