  If you have trouble with Chapter 7 Linking, I recommend reading the book *Programmer's Self-Cultivation*, subtitled link. load and library. This book can complete our understanding of program linking, and I believe after reading this book you will have a deeper comprehension of program linking, ELF files, and dynamic libraries. It is highly recommended to be read as a supplementary material after reading CSAPP and having a certain understanding of computer systems.

+# CS162: Operating System
+
+## Descriptions
+
+- Offered by: UC Berkeley
+- Prerequisites: CS61A, CS61B, CS61C
+- Programming Languages: C, x86 Assembly
+- Difficulty: 🌟🌟🌟🌟🌟🌟
+- Class Hour: 200 hours+
+
+The course impressed me in two aspects:
+
+Firstly, the textbook: *Operating Systems: Principles and Practice (2nd Edition)* is written in an insightful but easy-to-understand way, well compensated for the lack of theoretical knowledge in MIT6.S081, I highly recommend you to read this book.
+
+Secondly, the project for this course *Pintos* is is a great journey for system hackers. *Pintos* is a toy operating system developed at Stanford for educational use. 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.
+
+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.

 The class is extremely friendly to novices, and Andrew has the ability to make machine learning as straightforward as 1+1=2. You'll learn about linear regression, logistic regression, support vector machines, unsupervised learning, dimensionality reduction, anomaly detection, and recommender systems, etc. and solidify your understanding with hands-on programming. The quality of the assignments needs no word to say. With detailed code frameworks and practical background, you can use what you've learned to solve real problems.
