Department of Electrical and Computer Engineering
University of Alberta

Announcements:

Assignment 2, 3, 4, and 5 solutions have been posted. The solutions to quiz #2 and the midterm have also been posted. I have uploaded all the grades for lab #3 to CCNet and the labs are available for pickup in the CMPE401 lab. I will also be posting the prelab and the demo marks to CCNet today. Please verify your marks and notify Dr. Jarillo of any changes given that I will be away starting Sunday. Yifan has begun marking lab #4 and will port the marks to CCNet as soon as he is finished. I will be in the lab today after lunch at approximately 1:30 PM to meet up with the 2 groups that have not yet retunred their kits.[December 7th, 2007]
Please note that the Lab #4 Ex3 instructions incorrectly state that the direction and the steps are sent to the server as a POST request. The field info may be encoded in a GET or POST request. [November 29, 2007]
Assignment #5 is available below. [November 27, 2007]
The link for CCNet is here: CCNet Login CMPE401 [November 26, 2007]
CCNet accounts have been created for all of the students. Please login, provide an email address and verify the grades that I have put in for you. Please notify me of any recording or additions errors ASAP. I have placed all grades that I have recorded to date, including lab #4 prelabs and demos. Lab #2 reports and regrades for lab #1 have been placed on the ledge near the blackboard in the CMPE401 lab. Please contact Yifan (email address below) for any questions regarding the marking on lab #2. I'll be in the lab on Monday between 2-6 or so to take care of demos. If that period does not work for you send me an email. I am usually in around 10 AM or so, and I will be checking my email this weekend from home. Nancy. [November 23, 2007]
The httpd.c code I provided in the tar file can produce exceptions in some circumstances and execute correctly in others. I have rewritten it to eliminate the inconsistency. Get it here. Deadline dates for the demo have been adjusted for all sections to Monday, November 26th to compensate for my error. I will be in the lab on Monday November 26th as long as necessary to complete all the demos. That means that for those of you that have labs on Monday until 5 PM I will be available after 5 PM to make sure that you can demo. All reports are due on Tuesday November 27th for all sections. My apologies for the inadvertent error. It's small but significant. Deadline dates for Lab #4 remain unchanged. Nancy. [November 19, 2007]

Code of Student Behaviour:

It is the student's responsibility to be familiar with, and to adhere to, the terms of the University of Alberta's Code of Student Behaviour. Included in the Code are descriptions of unacceptable behaviour for students attending the University, the sanctions for the commission of academic offences, and explanations of the complete discipline and appeal procedures. In particular, please note the definitions of plagiarism in section 30.3.2(1), of cheating in section 30.3.2(2), of misrepresentation of facts in section 30.3.6(4), and of participation in an offence in section 30.3.6(5). For example, cheating includes the submitting of the words, ideas, images, or data (including computer programs) of another person as the student's own in any academic writing, essay, thesis, research project or assignment in a course or program of study. Penalties for academic offences range from a written reprimand up to expulsion from the University.

Supplementary Reference Materials:

Please do not feel obligated to buy copies of any of these books. They are not required for the course, but you might find some of these titles useful to supplement the lecture and laboratory material. Limited numbers of the book on MicroC/OS-II by Jean Labrosse are available in the University bookstore. This book would be a useful reference for the laboratory exercises, and might be useful later on for project courses.
