This course assumes familiarity with basic computer organization (e.g., processors, memory, and I/O devices as covered in cs354) and data structures (e.g., stacks and hash tables). You will need to be able to program in
C
(not C++, and definitely Java) to perform the assignments in the course. If you don't have much experience in this language, don't worry (too much), we will spend some time covering background, but of course, learning on your own is important and valuable (in this class and in real life). For those of you who are new to C (e.g., you just know Java), realize this is an opportunity to broaden your skill set! (i.e., stop complaining).
However, you can check the
archives
to see if you've missed anything.
There is also a project question mailing list (537proj@cs.wisc.edu). Check the 537proj@cs.wisc.edu mailing list
archive
for Q and A about the projects.
You should have ONE of the following two textbooks:
Operating Systems (3rd Edition)You should also own:
Deitel, Deitel, Choffnes
ISBN: 0-13-182827-4
Pearson, Prentice Hall
Operating System Concepts (6th or 7th Edition)
Silberschatz, Galvin, Gagne
ISBN: 0-471-25060-0
Wiley
The C Programming Language (2nd edition)
Kernighan and Ritchie
ISBN: 0-13-110362-8 (paperback)
Prentice Hall
You must use C on the system programming assignments in the class. The best C book in the world is
Kernighan and Ritchie's
beautifully sparse
The C Programming Language.
It is worth purchasing. Also useful is
Expert C Programming
by
Peter Van der Linden.
Finally, if you are interested in mastering the Unix programming environment, the absolute bible is
Advanced Programming in the UNIX Environment
by the late, great
W. Richard Stevens.
Buy this book too; it is worth every penny.
Here is a short, free, and incomplete overview of the C programming environment by y.t., available for your viewing convenience in both
Postscript
and
PDF.
It would also be useful to figure out how to use the debugger,
gdb.
Here is a
link
to a short tutorial -- there are others on the web too. Learning how to use such tools is a good idea.
Project 1 (due Thursday, September 22 at 9pm).
Project 2 (due Thursday, October 20 at 9pm).
Project 3 (due Tuesday, November 22 at 10pm).
Project 4 (due Thursday, December 15, at 10pm).
As part of the course, you will complete four or five programming assignments. You may perform these projects on PCs running the Linux operating system.
New Unix users and novice Unix users new to the CSL Unix facilities are encouraged to attend an orientation session as early in the semester as possible. You may also purchase a copy of
CS 1000
(An Introductory Manual to the Unix Operating System and the Computer Sciences Department's Instructional Computing Environment) at the DoIT Tech Store (first floor of the Computer Sciences and Statistics Building).
The projects are a fundamental part of this course. Although the first assignment will be relatively easy, the remaining projects each require a significant amount of time, so
do not procrastinate!
It is likely things will take longer than you expect. Do not wait until the day before the assignment is due to start. These assignments should be
started well over a week
before they are due, ideally right when they are handed out. All information necessary to complete the assignments will be available from the class web page.
As stated above, all of the assignments will be in C and not Java. We assume that you have enough programming background that learning the basics of a new language (if it is indeed new to you) will not be difficult. C is actually quite similar to Java, as those who invented Java were C experts.
For the projects, you will be graded on how well your implementation works. We will test your program on a suite of input sets. Your grade will be based on how many of the tests your application passes and how well you are able to answer our questions about the program; we will only briefly examine your code to ensure that you followed the specifications of the assignment.
Questions about projects should be sent to
537proj@cs.
Those queries (and responses) are archived at
this url.
The
first midterm
will be held
October 25th
in class.
For each
exam,
a single page "cheat sheet" (8.5 by 11 inches) is allowed, and you can use both sides; exams are otherwise
closed-book
and
closed-note.
