Course Info

Welcome to CS223: Systems Programming!

matrix original

Systems programming is the foundation for creating software that serves as controllers and infrastructure, such as drivers, embedded system controllers, compilers, databases, operating systems, networking APIs, and graphics engines. Systems programming involves writing code that directly interacts with hardware, memory, or the operating system. Class topics include pointers, bit representations of data, x86_64 assembly, memory management, processes, and threads. In this class, students will gain hands-on experience implementing low-level algorithms and data structures using C. Additionally, students will build technical skills related to makefiles, interactive debugging, version control, and command-line shell interaction. C++ and STL will be introduced at the end of the course.

Academic Integrity

At Bryn Mawr, we assume students are trustworthy and work with honesty and integrity. Look here for information about Bryn Mawr’s Honor Code.. Midterms and the final will be closed book. Lab coding challenges will be open-book and closed-internet. Thus, you cannot use VS Code, internet browsers, and other programming aids. However, you can use the text book, Dive into Systems, the Linux Programming Manual (available with man), and your class notes. You may work with others and with online materials for assignments, but you will be expected to explain and reproduce your submitted assignment on your own.

Academic Accommodations

To receive an accommodation for a course activity (such as more time on quizzes and exams), you must have an Accommodation Letter from the Office of Student Disability Services and you need to contact us to work out the details of your accommodation at least two weeks prior to the activity. Forms can be emailed to me, the instructor.

You are also welcome to contact us privately to discuss your academic needs. However, all disability-related accommodations must be arranged, in advance, through Student Disability Services. Also note that accommodations are not retroactive and require advance notice to implement. More information can be obtained at the Access Services website. (http://www.brynmawr.edu/access-services/)
