Cheat sheet addendum

There is a small correction to the cheat sheet policy discussed in recitation today. You may type your cheat sheet, but it must be your own (of course, you can talk about the course material with other students). Also, there have been a few announcements recently; click "Older Posts" to see all recent annoucements.

Additional office hour

For those who have missed my office hour last week and (possibly) this week due to my mistake updating the google calender correctly, I'll hold an additional office hour next tuesday (Oct 6th) from 11:00 to 11:50, before the exam at Wean 8th floor couches. Since it's before the exam, please bring specific questions so that we can go over as many questions as possible.

Jeff's office hours 10/5

I'm moving my office hours next week to October 5th, 4:30pm-5:30pm, in GHC 4122, so as to better help you prepare for the midterm on October 6th.

Daegun's office hour confusion

It seems like I didn't update the google calender properly to show my office hour that I moved last week. If anyone came to my previous office hour and waited for me, I apologize for your inconvenience. It's now corrected. Again, sorry for the confusion.

Please Include Link to Frontdesk Submission in DBoard Posts

If you have a question about a specific error or case that you are seeing on Frontdesk, please include a link to your submission so the course staff can quickly find your submission. At the very least, post your andrew id as that is the index the staff has for searching for submission.

Watching 211 videos

Here is how to watch: Click on the "Lectures" link on the left. Click on a video. You may be asked to authenticate with your andrew password.
  • Principal uses of the video are: (1) using lecture content to find answers to specific technical questions, (2) get clarification on some part of the lecture that may have been confusing the first time around, and (3) review later in the semester. Videos are less effective as a lecture substitute -- better to attend the live event.
  • Some how-to info: (1) Use the slide tray on the bottom to navigate -- just click on a slide or image. (2) Click on the "powerpoint" tab above the main window to see the powerpoint slides rather than the video of the screen or the screen capture (when we do this). Select the "+" on upper right to expand the image. (3) Videos that show powerpoint directly have a search function on lower left that you can use to find specific material -- the index is built from text on the slides. (4) Try also the note-taking tab -- you can create your own private notes or a public channel.
  • If you can't get authenticated, read this: This system uses CMU's "active directory" (ANDREW.AD.CMU.EDU) domain and it has one glitch: If your authentication fails, go to myandrew and reset your password to itself. (Why this works I cannot explain.)
Let us know if any problems. --Bill
