Attendance at the last class was so low that I decided not to hand out the course evaluation forms. I will collect course evaluation forms at the final exam. However, since I know many people are not in the mood to do course evaluations during finals, I am putting the forms near the submission bin on the second floor of the Computer Science Building. You may take them when you come to hand in Problem Set 10 or pick up graded work, fill them out at your leisure, and turn them in at the final exam. Please take the few minutes to fill out these forms. Your feedback is important. If you would like to make any comments about lab instructors, please give your lab time. The registrar would also like your lab number from the list below on the optical scan form (note that they are neither in temporal order nor numbered consecutively):

Lab 1 Tues 1:30
Lab 2 Wed  1:30
Lab 3 Thur 1:30
Lab 5 Mon  1:30
Lab 8 Thur 7:00

12/13/99 second entry

• Copies of the paper "On the Politics of Search Engines -- and why it matters", which we will discuss on Wednesday, are in the return bin on the second floor of the Computer Science building.
• Professor LaPaugh will not have office hours today, but will have office hours Wednesday 2-3pm.
• We are providing printed copies of The Alice Tutorial in E203 for the lab this week. Please look for them.

12/13/99 Note that Problem Set 9 has a new due date of Thursday, December 16 at 5 pm.

12/3/99 Solutions to problem set 8 are now available (follow link). All problem set submissions through 8 have been graded and handed back; unclaimed papers are now in the return bin on the second floor of the Computer Science building.

12/3/99 IMPORTANT ANNOUNCEMENT: EXAM 2 HAS BEEN POSTPONED UNTIL WED 12/8/99 IN CLASS. ANYONE FOR WHOM THIS CAUSES A HARDSHIP SHOULD CONTACT PROFESSOR LAPAUGH IMMEDIATELY. Update 2:10pm: We will hold the review session on Sunday: 1:30 pm in Room 103 of the Computer Science Building.

12/3/99

• Now available (follow links): Solutions to Problem Set 5 and Solutions to Problem Set 7.
• A review session will be held by teaching assistant Scott Craver on Sunday, December 5 at 1:30pm, probably in room 103 on the first floor of the Computer Science Building. (Room confirmed Fri Dec 3 14:14:27 EST 1999.)

12/2/99 Now available (follow links):
Exam 2 and solutions from fall 1998. The coverage of material was different last year, so Problem 3, the programming aspects of Problem 4 and Problem 5 are on programming, which is not covered on exam 2 this year. You should also review Problem 5 from the first exam last year (see 10/19/99 "What's New" entry below).

11/30/99 Solutions to Problem Set 6 are now available here. We still owe you solutions to Problem Set 5.

11/23/99 The solutions to the first exam are now available here.

11/19/99 Warning: for about 5 minutes around 1am this morning, the extra credit problem for Problem Set 7 was listed as a regular problem. There are only 4 regular problems on this problem set.

11/12/99
Exams not picked up in class Wednesday or today are now down in the pick-up bin on the second floor of the Computer Science Building.

The mean of the test scores is 81 (we forgot to delete students who had not take the exam when we calculated the 79 that I announced in class) and the median is 86.

Midterm grades have been sent to the registrar and will be emailed to you by us along with the current grades we have for you. Please check the grades on your work for accuracy. The weight of the different components of the course used for midterm grades is that which will be used for final grades:

• Problem sets 1-4: 15%
• Lab reports 1-3 35%
• First in-class exam 50%

11/4/99 Copies of the transparencies used in lecture 10/27/99 and 10/29/99 for the material on operating systems are now available here.

10/22/99

• Graded submissions for Problem Sets 3 and 4 were returned in class. Unclaimed papers are now in the pick-up bin next to the submission bin on the second floor of the Computer Science Building. Scott Craver will bring these papers to the review session on Sunday.
• The complete solutions for Problem Set 4 are now available here.

10/21/99 -- updated 10/22/99

• A review session will be held by teaching assistant Scott Craver on Sunday, October 24 at 1:30pm, in room 103 on the first floor of the Computer Science Building.
• Solutions to Problem Set 2 are now available here.

10/20/99 noon -- updated 2pm

• Problem sets 1 and 2 have been returned. Papers not yet claimed are in the pick-up bin next to the submission bin on the second floor of the Computer Science Building.
• Solutions to problems 1 through 5 of Problem Set 4 are now available. The due date for problem 6 was extended; solutions for it will be posted after the due date. Superseded 10/22/99
• Solutions to Problem Set 3 are now available here. Watch this space for solutions to Problem Set 2. They will be available any time now.

10/19/99 The following sample exams are available (follow links).

• Exam 1 and solutions from fall 1998. Part b of Problem 5 on that exam is not covered in the exam this year; compression IS covered this year but was not last year; we did more work with algorithms at the beginning of the semester this year, and that may be reflected in the exam.
• The midterm exam and solutions from fall 1997. In fall 1997, there was only one in-class exam in the course; the coverage of material is even more different than last year's exam will be from this year's. In particular, problems 4 and 5 of that midterm exam are beyond what is covered in the first exam this year, and compression and algorithms are not represented on that exam.

10/18/99 Notes on Problem Set 4 due tomorrow:
Four of the problems are on material in Brookshear Chapter One. This includes hexadecimal notation, which I have not covered in class but expect you to read on your own.
The last two problems are from Brookshear Chapter Two. You should do Brookshear Problem 5 on page 108 in the style of Figures 2.2 and 2.3. My apologies for the misleading comment about using a subtraction instruction: the old edition of Brookshear had "x+y-z" rather than "x+y+z" and I did not notice the change.
Brookshear Problem 11 on page 109 does involve using instruction codes. If you are uncomfortable with this material from the reading alone, you may postpone handing in ONLY this problem until Friday, 10/22/99 during class. We will do examples of instruction codes on Wednesday.

10/11/99 Solutions to Problem Set One are now available here.

10/4/99 Two of the graduate teaching assistants have now posted office hours. See the course home page. Don't forget that you can also see any of us outsider office hours by appointment. Best way to make an appointment is through email.
