OS Re: Textbook

Dear students taking my OS course. In the previous article , we reported that the publisher will send us first two chapters of the textbook, but what we actually received was just Chapter 1. There also have been other issues related to the communication between us and the publisher and the bookstore. We hope to settle down this issue as soon as possible, you receive your own copy of the textbook, and review and prepare for the OS class using the textbook. If you have any question, or problem, please consult with the instructor.

OS Grade Reference ID

Each student registered for the Operating Systems class must have received email with subject "OS13 ID. Please keep this number." The message body of the email has a number by which you should be able to look up your exercise and exam grading (when they are available). If you are registered with the class but did not receive the email, please contact the instructor ASAP.
