The author Ben Pfaff even published a [paper](https://benpfaff.org/papers/pintos.pdf) to explain the design principles of *Pintos*. -Unlike the small but comprehensive design philosophy in MIT's xv6 labs, *Pintos* emphasizes system design and implementation more. The codebase is about 10,000 LOC and only provides the basic functions of a working operating system. The four Projects let you add scheduler (Project1), system calls (Project2), virtual memory (Project3), and the file system (Project4) to this extremely simple operating system. All projects leave a a big design space for students and require more than 2000 LOC. Based on the [feedback](https://www.quora.com/What-is-it-like-to-take-CS-140-Operating-Systems-at-Stanford) from Stanford students, the latter two projects take over 40 hours per person even in teams of 3-4 people. +Unlike the small but comprehensive design philosophy in MIT's xv6 labs, *Pintos* emphasizes system design and implementation more.

Although it is tough, Stanford, Berkeley, JHU and many other top U.S. colleges have chosen *Pintos* as their OS course project. If you're really interested in operating systems, it will greatly improve your ability to write and debug low-level system code. For me, it is an invaluable experience to design, implement, and debug a large system independently. -*Pintos* will also be introduced as a course project in Peking University's OS Course. In the Spring 2022 semester, I worked with [Another TA](https://github.com/AlfredThiel) to write a comprehensive [lab documentation](https://alfredthiel.gitbook.io/pintosbook/) and provided a docker image for the ease of cross-platform development. In the last semester before graduation, I hope such an attempt can make more people fall in love with systems and contribute to the field of systems in China. +*Pintos* will also be introduced as a course project in Peking University's OS Course.
