work as yours.

you will receive a severe penalty.

For this week only, we accept exercise work by 3pm without
penalty. Please come to Lab std2 (Research Quandrangles 146)
for submission. However, your answers will not be checked
before submission. It might be better to work on your exercise
problems more and submit next week (even with late submission
penalty).
10/24/05
As we review the exercise problems of the previous week
at the beginning of each lecture, a late submission is accepted
by then. This is changed from the policy in the Syllabus
"A late submission is accepted by the end of next week's lecture."
The late submission penalty is still -20% (unless otherwise
notified). Effectively, this amendment has already been made
for weeks in the class but is posted here as a reminder to
those who have never missed the in-class submission deadline.

On Oct 24, we cover Sections 2.5 "Scheduling."
It is assumed that each student has own copy of the textbook
and he/she reads the sections corresponding to the topics covered
by the lecture. While we cannot enforce this rule, you should
not expect that you can pass the course without reading textbook
(unless you already have 'near-professional' experiences
in this field).

of the textbook (Modern Operating Systems, 2ed). However, nine of
them are reserved for those who already ordered. Therefore,

delivery.
