The aim of CS214 is to introduce the student to the process of writing low-level
programs that interact directly with a computer's operating system and hardware,
as well as to develop the student's ability to build large applications in a
team environment. Upon completion of this course, the successful student should
be able to design, write, test, and analyze moderately complicated programs
using the C programming language and UNIX/Linux operating systems.
- Structured programming in a high-level language (such as Java).
- Standard data structures (lists, trees, graphs, hash tables).
The following text is used in this course:
Computer Systems - A Programmer's Perspective Second Edition
Randal Bryant and David O"Halloran
The following texts are available online, free of charge.
The textbooks do not cover all material discussed in class,
and are not a substitute for attending lectures.

And some notes for POSIX using mutexes and condition variables in shared memory.
And a toy program that sets up shared memory.
Students are expected to attend all lectures and perform all reading assignments prior to lecture. Students are also expected to attend all recitation section meetings. Students will be evaluated according to their performance on a semester long programming project, a mid-term examination, and a final examination.
WARNING: This is a project course, which means that this course should give you more than a passing knowledge of what writing working programs entails. The project will be a major undertaking. If you complete the programs, you will have learned a lot. However, assess your commitment to this course realistically. If you don't have the time or the inclination to work hard on the project, you would be better off not taking the course. You will have to learn how to build and debug reasonably sized C programs and make them robust to outside errors. You will also have to describe how your program work in a written document.
This one large project will be assigned, as three sub-projects. Up to 2 students can work as a group for each sub-project and you can change group members for each project . Students are required to complete the parts by the scheduled deadlines. Failure to turn in the project by the deadline using the electronic handin website will result in a zero for all team members. No exceptions!
There are many different operating systems and variants of C out there and we cannot test your program on all of them. So all program assignments must run on the local iLab Linux machines. We will be grading your assignments on those machines as well.
Working Together and Academic Honesty
Cheating on projects and exams will not be tolerated. We want to protect the fairness and integrity of the class, so we run code similarity detectors on the projects and scrutinize exams for copying. Both parties in the exchange are liable; e.g. if you give away solutions to friends, you're putting yourself at risk too. If you get caught, it's a nasty process--- just don't go there! You're better off asking for help, or at worst, dropping the course and trying it again.
The department academic integrity policy can be found at http://www.cs.rutgers.edu/policies/academicintegrity/. You now need to click explicitly on a link when first login to our computing facilities, use handin, etc., that says you acknowledge being aware of the policy (which you can read through the login screen). If you fail to do the click-through by the end of September, your access to our facilities will cease October 1.
Midterm: 20 %
Final: 30 %
The programming part of the projects are typically graded on how close they are to the functional requirements. The written portion is graded on how well the TAs can figure out how your project is constructed only from the written description. Exams are typically graded on a curve. As a rule of thumb, the mean is a "C'" and each standard deviation is one letter grade. This rule can be altered, however, if the class does exceptionally well or poorly.
I felt we should do our best to clarify up front how we grade your programming assignments. The TAs do the grading, but have all agreed to the same criteria for grading each programming assignment. Each programming assignment is worth 100 points. Here are our grading criteria:
80% A combination of the following factors:
- Correctness -- based on number of test cases
- Algorithmic quality
- 10% Test Cases from Students
- 10% Comments and Documentation (Analysis, readme files, etc...)
The Gilligan's Island Rule
We do encourage you to talk to your classmates, provided you follow the Gilligan's Island Rule. After a joint discussion of an assignment or problem, each student should discard all written material and then go do something mind-numbing for half an hour. For example, go watch an episode of Gilligan's Island (or jersey Shore in modern terms), and then recreate the solutions. The idea of this policy is to ensure that you fully understand the solutions or ideas that the group came up with.
If you follow the Gilligan's island rule, often best route to follow to get a question answered is to ask, in order:
1. A classmate smarter than you.
2. Your TA.
3. The professor.
