- Our main objective is to learn how modern operating systems are designed,
through study of their fundamental pieces and through studying, modifying,
and building upon the Linux kernel. At the end of the course, you will be
- Describe the fundamental principles of concurrent processes/threads
and manage that concurrency.
- Explain that an operating system is a collection of algorithms and
data structures, giving illustrations.
- Assess the various CPU and disk scheduling algorithms.
- Analyze the memory management components of operating systems.
- Implement new system calls in Linux.

- Grade Distribution
A = [92%-100%],
A- = [90%-92%),
B+ = [88%-90%),
B = [82%-88%),
B- = [80%-82%),
etc. Grades are ``one point rounded.''
Course Point Distribution
The following is tentative. There are approximately 1,000 total points for
- Assignments and projects -- There will be six written
assignments. Each assignment will be worth 30 points. There will be
two projects involving the Linux kernel:
These projects will be implemented within a virtualized Linux
environment. 300 points total for assignments and projects.
- Implement a loadable kernel module, 60 points.
- Implement a system call, 60 points.
- Quizzes. There will be approximately 10 weekly quizzes. Each
quiz will be worth 10 points and will be taken outside of class.
100 points total for quizzes.
- Semester exams. There will be two exams, tentatively on the
following dates: Feb. 27 and Apr. 9. Each will be worth 150 points.
If you need to re-schedule an exam, it is your responsibility to let
me know a few days beforehand. 300 points total for exams.
- Final. There will be a cumulative final, scheduled by SAS. The
final is worth 300 points.
- Academic dishonesty will not be tolerated. We are all bound by the
Academic Honor Code.
- Course Handouts:
Course handouts may be made available once in class. After that, they may
be obtained from the class home page.
- Attendance of classes is expected. It is your responsibility to catch up
on missed class work.
- Electronic Communication:
From time-to-time, I will need to send e-mail messages to the class. These
messages will be addressed to your official Goucher e-mail addresses. You
are responsible for checking your e-mail on a timely basis.
- Cell phones must be turned off or set to ``silent'' during class. If you
must enter late, do so as unobtrusively as possible. Likewise if you must
leave early. Please use mental telepathy if you must hold a personal
conference during class. I have ways of making you not talk!
- Any student with a documented disability should contact the Academic Center
for Excellence (ACE) to arrange for academic accommodations for the course.
Carefully follow all ACE's policies and procedures. Once you have
coordinated with ACE, email me to make me aware of your accommodation. I
will receive official correspondence from ACE; however, I would also like
to receive an email from all students requiring accommodations for the
semester. If your accommodation involves taking exams at ACE, it is your
responsibility to schedule your exams with ACE. When scheduling exams with
ACE, be sure to carbon copy me on any emails with ACE so that I have
confirmation that everything is in order. This process is to be repeated
for all exams throughout the semester.
- Achieving Academic Success:
If you are struggling in this or other courses, I strongly encourage you to
reach out for help sooner rather than later. Proactive strategies could
include contacting the instructor directly, attending office hours, and/or
taking advantage of the multitude of academic services that the Academic
Center for Excellence offers. The responsibility is upon you to recognize
when you need help and to take the steps necessary to succeed. Goucher
College has a variety of resources available to help you succeed in your
classes; use them!
According to the Goucher College policy on Student-Athlete
Responsibilities, all student-athletes are expected to contact me at the
beginning of the semester to request approval for absences associated with
athletic events (or scheduled departure times for such events) that conflict
with the regularly scheduled class time. The approved absences will then be
listed on a contract signed by both me and the student-athlete.
Additionally, it is the responsibility of the student-athlete to complete
all assignments covered in class during the approved absences and to obtain
all handouts, assignments, and notes from the missed class(es).
Student-athletes who fail to coordinate with me prior to any class absences
will not be permitted to make-up missed assignments.
- Student Responsibilities in Academic Conflicts (Field trips,
According to the Goucher College policy on Academic Conflicts, all students
in situations in which you are confronted with obligations or
responsibilities (ranging from participation in field trips in the visual
arts or the sciences or rehearsals or performances in the performing arts
to extra-curricula activities at which students are representing the
college such as model senate events or varsity athletic contests) that
conflict with regularly scheduled academic classes, are expected to contact
me at the beginning of the semester, or as soon as the conflict is known,
to request approval for absences that conflict with the regularly scheduled
class time. The approved absences will then be listed on a contract signed
by both myself and the student. Additionally, it is the responsibility of
the student to complete all assignments covered in class during the
approved absences and to obtain all handouts, assignments, and notes from
the missed class(es). Students who fail to coordinate with me prior to any
class absences will not be permitted to make-up missed assignments.
