We aim to introduce students to the concepts, tools, and framework necessary for independent work on the Linux kernel, and more broadly to the skills necessary for work as a professional open source software engineer.
Linux is the most widely used operating system in the world. It powers the world's top supercomputers, every android phone, and the servers that host the internet's most popular websites. At the core of Linux is a software component called the kernel. It performs critical roles including managing communication with hardware, sharing system resources equitably, and enforcing security constraints. This course will introduce students to Linux kernel development through hands-on experience working with internal Linux kernel APIs and providing an overview of some of the core features and components of the kernel. Students will gain an invaluable perspective on how their computers work behind the scenes. By grasping the inner workings of the operating system and how to make changes to it, they will add a new layer of understanding to their mental model of computation that will pay dividends throughout their future in software engineering.
Students will:
Stretch their C programming skills to the limit
Develop the ability to autonomously participate in the open source software community
Learn how to give and receive feedback on code patches
Demonstrate the ability to explain your code and your knowledge of Linux in your own words
Create, develop, and test interesting and creative Linux kernel modules
Extend their Linux kernel internals knowledge
A computer that can run a virtual machine to give you access to a Linux environment.
Patience, determination, and an ability to focus on a potentially frustrating task for sustained periods of time.
The ability to join a live video call with camera/microphone from that computer (i.e. the necessary equipment and a stable internet connection)
Students will complete a coding assignment about once a week
Assignment submissions are git patches formatted for email
Assignments fall into three categories: exercises, programs, and the final project
Exercises are about practicing skills and learning by doing
Students will follow a series of instructions (e.g. to execute certain commands), and answer questions about what they did
A submission will be proof that the student completed the steps correctly, and their answers to the questions
As a general rule exercises will not involve much programming, and are weighted lesser in the overall course grade
Programs are about getting your hands dirty and actually writing some code
Students will have specific requirements their code has to meet, and a way to test that what they have written completes the requirements successfully.
A submission will consists of proof that the program works correctly, and its source code.
Since programs involve more actual coding, they will be weighted more in the overall course grade.
The final project is broken into two parts
The students will have freedom to engineer a creative project
However, there is an emphasis on designing rigorous specifications and tests to clarify and enforce that vision
The student will implement a peers specification instead of their own.
As a part of every assignment (except the very final one) students will perform peer review
Students will be assigned two others' submissions to review
Part of the grade on each assignment will be determined by the quality and thoroughness of the review
Students will be required to complete two presentations throughout the course
Students must record and upload their midpoint presentations by the due date
Students must deliver their final presentations over a live video call (with a camera)
Presentations must include original visual content, such as slides
Students are required to include live demonstrations of their code by sharing their screen during the presentation
Category | Percentage |
---|---|
Programs | 35% |
Exercises | 20% |
Midpoint Presentation | 15% |
Final Assignment + Final Presentation | 30% |
Attendance is required.
The instructors will be joining remotely
Students are required to join the lecture zoom meeting to attend the course
If a student fails to complete a task by a deadline with no prior notice, an instructor will reach out to you via email and direct message on matrix. If the student fails to respond to this message within seven days of it's receipt, the instructors reserve the right to give the student a final course grade of 0.
During a week where an assignment is due, the students must make two submissions and complete two peer reviews in three stages as follows:
By 23:59 Monday, a student must make at least one submission. This is the "initial submission" stage. The student will not be graded on the content of this submission, however the student will receive a 0 for the assignment if they do not submit anything at all. Students may make as many resubmissions as they please, and only the last submission made before the initial submission deadline will be distributed as the target of peer review. Students will review each other's initial submissions in the following stage.
By 23:59 Tuesday, a student must reply by email to two other students' initial submissions providing feedback on anything wrong with the patchset and any suggestions for the other student to improve their final submission. This is the "peer review" stage. Triggered by the event of the initial submission deadline, automation will make all students' submissions visible to the whole class and assign each student two others to peer review. Each peer review will comprise 10% of a students' assignment grade, for 20% of the total.
By 23:59 Wednesday, a student must make at least one more submission for the assignment. This is the "final submission" stage. The wise students will take their peer's feedback and self-reflection into account and revise their work before the final submission, however they are not required to do so. Students can re-submit as many times as they please and they will only be graded on the content of last submission made before the deadline, provided they made at least one initial submission. The grade students receive on the content of the final submission will comprise 80% of their assignment grade. Even if you are satisified with your initial submission, you must make at least one final submission. Failure to make at least one final submission will result in a grade of zero.
The times listed above are in Israel Daylight Time, which corresponds to the instructors' 16:59 Eastern Daylight Time in Boston, USA.
Instructors reserve the right to delay due dates within reason
In such a case, we will provide advance notice to students
If the due date is being pushed forward, the notification will occur at least one week before the new due date
The instructors will not accept late work
Students receive a zero for assignments not submitted on time
With advance notice, the instructors will appropriately accommodate students who have reserve duty to ensure they have the opportunity to receive full credit
One exception (a once per semester get out of jail free card):
Students may choose to opt out of the peer review process for a given coding assignment
By skipping the process---both giving and receiving---students can use the two days that the process would normally entail to take more time to work on their final (and only) submission.
Skipping peer review means forgoing the safety net of receiving early feedback from peers, so it is the sole responsibility of the student who chooses this path to ensure that their work is correct lest any defects in the submission negatively impact their final grade.
The primary location for course-related communication will be on the instructor-hosted matrix server
Students will be provided access credentials at the start of the course
These will be the same credentials students will use to access the course email patch submission system for assignments
Students who have general questions about the course material or any other non-private course-related information will post their questions in the #questions channel on matrix where discussion and answers will be available to all course participants.
Students who have private questions about the course will reach out to a provided email address with their concerns.
