Today's Office Hours

Today, I'll be in 241-F (the conference room next to our lab) from around 3pm.

No OS Class Next Week

Due to the business trip of the instructor, OS classes for the next week (both lecture and exercise) have been cancelled. We will resume the class from the week after next, from Section 2.3 "Interprocess Communication" of the textbook.

The students who had difficulties in solving today's exercise should have one or more of the following reasons:

• Lack of understanding in the course materials presented so far (this almost means the sections of the textbook covered so far),
• Lack of proficiency in C-programming language and Unix (Solaris), or more in general, computer literacy,
• Lack of problem solving capability (such as breaking down the objective into smaller goals and finding the procedure/steps to achieve these goals).

Please try to identify your weak points and conquer them in this two week-break.

Course Directory

No student may write or modify files in the course directory (/home/course/os09f6/) . You may only copy or execute files there as directed in the exercise problems. From now on, any student violating this (very simple) rule will receive a penalty.

Section 2.1 This week

This week, we will cover Section 2.1 "Threads." It looks many students need to read course overview slides again.

Operating Systems ID

Students taking my operating systems course must have received email with subject "Operating Systems ID" . It contains a number which you will need to look-up your exercise grades (which will be posted by the TA when grading has been finished).

Next Week

Next week, we will cover Section 2.1 Process and possibly proceed to Section 2.2 Threads of the textbook. These sections are your reading assignment.

As previously announced, the classes on October 22 and 23 are cancelled. To make up these cancelled classes, next week's lecture should be slightly extended and we will work on the exercise problems during 4th and 5th periods at the lab std2 (Research Quandangles 146).
