Final Exam Grades

The final exam grades are up on FrontDesk. I have also updated the averages for all of the assignments in the course (including the final) on my AFS.

Final Exam Office Hour

Office hour will be in Morewood clusters. Owen and I (Karl) will be there. Office hour will run from 8:00pm to 9:00pm (or 9:30pm if many people show up).

Chess Results on FrontDesk

I ran the scripts and everyone should now have graded items on FrontDesk for bachchoy, jackbach, and the 211 pool extra credit. Please check that your grades are correct, and email me if there are any problems. Note that each of these items are just added to the rest of your score on the chess assignment (when we do final grades).

Chess

The chess assignment has been released. The chess server account sign-up page is now up and running. You will need to enter your andrew id, a handle for your chess server account, and a password for your chess server account. This password is not secure and should not be a password you use for anything else. Your server handle will be shown when you play games, on the ranking site (yet to be activated), and when people see who is online. You should receive a confirmation email (on andrew) after your account has been created. If you have any problems with account creation, email Owen. http://www.link.cs.cmu.edu/211/sign-up.html If you have any questions, please try ask in the appropriate thread on the DBoard.

Professor Sleator's office hours

I'll be having office hours Thursdsay and Friday from 3pm to 5pm both days. My office is Wean 4128.

Chess Bot Results Page

You can determine your last 10 wins/losses/ties against BachChoy and JackBach by visiting http://boojum.link.cs.cmu.edu/211/chess-results.html. Also, as discussed in the assignment documentation, we will be resetting the 211 pool ratings at 5pm today, Wednesday, April 30. If you wish to compete in the pool for extra credit, you will need to play at least 20 games in the pool by Friday, May 2 at 11:59pm. See the assignment documentation for how these metrics factors into your grade for this assignment.

Office hour moved

I'll have my office hour tomorrow (4/29) from 6:30-7:30 (30 mins earlier than usual) at WeH 7th floor couches. Sorry for any confusion this might cause.

Errors in Non-Essential ArrayBoard Functions

A student recently found a bug in ArrayBoard.countOfColor() and ArrayBoard.countOfType(). If you do not use either function, then you don't have to change anything. If you do use either function (they are probably throwing exceptions), see the topic on the discussion board with the fix. I apologize for any problems this may have caused.

Office Hour Move 4/25

I have 3 project/poster/design review due within the next day so I'll be moving my office hour to Saturday (4/26) at 6:00pm-7:00pm in Morewood Clusters.

NO RECITATION TOMORROW (ALL SECTIONS)

To give you more time to work on chess, there will be no recitation this week (April 23rd), regardless of the sections. The week after will be a optional make-up quiz (April 30th), so don't forget to come to the recitation next week if you want to take the quiz. You will also be given an opportunity to complete TA evaluations on the 30th. And good luck on your chess assignment!

Cancelled Office Hours

Unfortunately, I need to cancel my office hours for today (4/22) due to a not so sudden illness. I apologize for any inconvience that this creates.

Offline TextChess Fixes

There were a few bugs with the interaction between the provided ArrayBoard class and the offline TextChess class. If you have already downloaded the stubs and want to use the TextChess class, please see the discussion board for the specifics of what was changed. If you have not yet downloaded the stubs or you only care about playing on the chess server (online), then you don't have to do anything. Sorry for the inconvenience. Direct questions about these fixes to Owen.

Tomorrow's recitation change

For tomorrow's section, Owen's going to be at section H, and Daegun's going to be at section D. Also, for those who didn't realize yet, we will have a quiz on graphs, so make sure you come to the recitation. Good luck!

Tuesday office hour change

I need to move my office hour today. I will be holding it 2 hours later at 9:00-10:00, at Wean Hall 8th floor couches.

Graphs Recitation Material

The slides and handout from last recitation on graph algorithms are now posted.

Thursday Office Hour Change

I need to move my office hours this Thursday on account of an evening exam. I will be holding them 30 minutes earlier at 4:30-5:30, and will be unable to stay past 5:30.

Late Days

Since some of you are going to be asking about late days for compression, here is our policy:

You are only allowed to use a late day if both partners can use a late day. If one partner has used all of their late days, even if the other partner has all five remaining, no late days can be used.

The other thing that you should be aware of is that there will be no late days allowed on the last assignment, so for compression and the next assignment, we will allow you to use up to three late days (rather than the standard two).

Possible Office Hour Location Change

There are 15-451 group presentations this week, which, as you may remember, were in my office hour room (WeH 3130) last time. If the room is occupied again, I'll be holding office hours near the Wean 7th or 8th floor couches (depending on which one is available).

Burrows-Wheeler Transform Header

We did not fully specify the Burrows-Wheeler Header format in the assignment writeup, so please follow this addendum: Your header must be the first four bytes of the transformed files. It stores the start index value from highest order byte to lowest order byte. The provided example files reflect this header format for comparison purposes. Sorry for any confusion this caused.

Office hour moved for this week

I'm moving my office hour on 3/18 to 9:00 PM on Thursday, at WeH 8th floor couches. This change is for this week only.
