Textbook for OS and AOS

The Operating Systems class and the Advanced Operating Systems class will use the same textbook, Modern Operating Systems, 3rd edtion, by Andrew S. Tanenbaum (the latter course is in the graduate program and will go through different chapters than undergrad, off course).

Undergrad students will receive email from the university bookstore regarding the textbook order for the 2nd semester soon. There are several reasons you should order the textbook through the bookstore:

  • the Japanese subsidiary of the publisher gives us a deep discount (you should compare it with that of amazon, for example),
  • since the import books cannot be returned, the bookstore orders a limited quantity. If you miss the first batch of the orders, you won't get it for several weeks after the semester. You might have come an easy way that you didn't have to buy textbooks (even thought you were required), but it is not the case this time.
  • The book is a very popular, standard and well written as a reading material. For some of you, to take a course might have meant, copy-and-paste web search results and collecting past-exam problems. Now it's time for reading comprehension.

Friday, June 22, 2012

AOS Syllabus Revised

The (tentative) syllabus of the Advanced Operating Systems has been revised.

  • Textbook will be Modern Operating Systems, International Edition, 3/E (the same book as the undergrad. Operating Systems, but will use the Chapters of advanced topics),
  • The (tentative) schedule has been significantly revised.
If you plan to take (or are interested in taking) the course, please contact the instructor.

OS11 Disqualification

All the exercise submissions have been graded and the results have been posted at the Exercise Grade page. Those who disqualified for the class (due to six or more missed/poor submissions) have received email from the instructor.

Please note that this year, we had 'pre-lecture' exercise problems and more exercise problems were expected than pas year. In fact, we only had 14 Exercises and we had to use the same guideline as the past (i.e. 5 or more missed submission for disqualification). However, the revision has already been announed on this board (6 or more for disqualification), we decided to stick with this revised guideline.

The results of Exercise and Exams have been posted on the web. Those who disqualified should be advised that you needed to understand your situation and had to ask questions (or ask assistance) to the teaching staff. If your exercise or exam was graded poor, you should understand that you found points to improve.

Review of Mid-Term Exam

Review of Mid-Term Exam was graded and posted at TA's page. The exam was graded on out of 101 point scale (same as the Mid Term Exam) but will be scaled to 10 points and will be added to your final grade as extra credit.

Those who did now show improvement over the Mid Term Exam, you missed chances to learn what you did not understand.

Exercise Grades Posted

We have completed grading exercise problems up to Exercise 12 and TA has posted the grades on his page.

The Curriculum Guide (Examinations and Assessment of Academic Performance) of the Student Affairs Division says that students need to attend 2/3 of the classes. We measure it by the number of valid exercise submissions. This year, since we will have fourteen exercise in total, if you have missed six or more submissions*, you will disqualify for the final exam. If you have any valid reason for missed submission, you have to contact the instructor immediately. When we have graded the exercise problem of the next year (Exercise 14), those who disqualify will be notified.

(* In Syllabus, it is mentioned that "more than four (i.e. >= 5)" missed submissions disqualify the students, but this year we have more exercise problems that past years and the policy was amended).
