CPS 444/544: UNIX/Linux Programming

Department of Computer Science, University of Dayton

Fall 2017

Table of Contents (TOC)

Course Description

CPS [45]44 (3 hours) prepares students for developing software in the UNIX/Linux environment using the C and Go programming languages. Topics include libraries and system calls, shells, system structures and internals, interprocess communication (pipes and signals), communicating sequential processes, network programming (client-server model and sockets), configuration and compilation management, pattern matching and filters, shell programming, automatic program generation, and GUI programming. Students can also expect a survey of various software tools supporting systems programming, including gcc, gdb, make, git, sed and awk, and lex and yacc. The course does not aim to be comprehensive, but rather focuses on thematic issues. Assignments are designed to provide students with a pragmatic exposure to these tools as well as issues faced by modern practitioners. CPS [45]44 is a programming-intensive course.

How to submit

Note: All directory and filenames below are case-sensitive. You must use the directory and filenames exactly as shown below (i.e., all lower case).

Include a README file in the hw6 directory answering the following questions: What keeps the server running, even after all of the client processes have terminated? Is it possible for a malicous client to bring the server down?

When you structure your project directory as shown above simply tar the hw6 directory as follows: tar cvf hw6.tar hw6/. This will make it easy both for you to submit and us to grade because your submission will already contain the source code files supplied to you.

Only the file /home/<logname>/homeworks/hw6/hw6.tar will be electronically collected from your account on the deadline.

Failure to follow these submission requirements will result in a 10% penalty.

Evaluation Criteria

(point values below are approximate)
Component Quantity Points per Total points
Homeworks ~10 varies (+80 EC) 500
CPS 544 Project 1 200 200
Quizzes ~10 varies 350
Final exam or project (comprehensive) 1 150 150
CPS 444 Total:1,000
CPS 544 Total:1,200

Homeworks involves analytical, theoretical, and programming exercises. The programming requires a fair amount of critical thought and design, and approximately 500-1000 lines of code. To prepare students for the realities of computer science problems in industry and graduate school (and beyond) this course encourages (and rewards) self-reliance and independent, self-directed work. Handwritten assignments are not accepted. Assignments are due at 2:00pm in class. Late assignments are not accepted. No exceptions. All exams are in-class, closed-book, and closed-notes. Attendance is mandatory at all examinations; make-ups are not given. Any missed examination will result in a zero. Make no assumptions about anything; always consult the instructor first. Final letter grades of A, A-, B+, B, B-, C+, C, C-, and D start approximately at 93, 90, 87, 83, 80, 77, 73, 70, and 60 percent, respectively.

TOC

Workload

CPS [45]44 is a challenging course and moves at a very fast pace. Spending a minimum of 9 hours outside of class each week reading, studying, and programming is required. I advise you to see me to discuss any problems you may have before you are evaluated.

TOC

Classsroom & Course Policies

Students are expected to conduct themselves with respect, integrity, and virtue. Keep phones and similar devices in a silent mode and put away during class (i.e., out of sight). The use of laptop computers and similar devices is not permitted in class. Audio or video recording of any kind in class is strictly prohibited.

TOC

Academic Integrity

To achieve the course objectives, homework assignments must be a sole result of your work, not be shared with other students, and prepared in accordance with the University Honor Pledge (see below). Moreover, you may not plagiarize code from any, cited or uncited, textbooks, online resources, or other authors. There is no team, group-work assignments in this class. Discussions among classmates must never include pending assignments. No exemptions. All questions and comments about a pending assignment must only be directed to the instructor and teaching assistants. Evidence indicating a violation of this policy will be handled according to the University Academic Honor Code and result in a doubly-weighted zero which will not be dropped (e.g., if the assignment is worth 100 points, you receive a 0/200) or a zero on the next exam. Make no assumptions about this policy; always consult the instructor first. No student should ever feel that they must resort to academic dishonesty. You are encouraged to consult the instructor if you are struggling with the course or an assignment. No grade is worth your integrity. Honesty in your academic work will develop into professional integrity. The faculty and students of the University of Dayton will not tolerate any form of academic dishonesty.

The Honor Pledge as listed in the Academic Honor Code section of the Undergraduate Catalog applies in full to CPS 444.

The Honor Pledge as listed in the Academic Honor Code section of the Graduate Catalog applies in full to CPS 544.
