<li>课程难度：🌟🌟🌟🌟🌟🌟</li> <li>预计学时：200 小时+，上不封顶</li> </ul> <p>这门课让我记忆犹新的有两个部分：</p> <p>首先是教材，这本书用的教材 <em>Operating Systems: Principles and Practice (2nd Edition)</em> 一共四卷，写得非常深入浅出，很好地弥补了 MIT6.S081 在理论知识上的些许空白，非常建议大家阅读。相关资源会分享在本书的经典书籍推荐模块。</p> <p>其次是这门课的 Project —— Pintos。Pintos 是由 Ben Pfaff 等人在 x86 平台上编写的教学用操作系统，Ben Pfaff 甚至专门发了篇 <a href=https://benpfaff.org/papers/pintos.pdf>paper</a> 来阐述 Pintos 的设计思想。</p> <p>和 MIT 的 xv6 小而精的 lab 设计理念不同，Pintos 更注重系统的 Design and Implementation。Pintos 本身仅一万行左右，只提供了操作系统最基本的功能。而 4 个Project，就是让你在这个极为精简的操作系统之上，分别为其增加线程调度机制 (Project1)，系统调用 (Project2)，虚拟内存 (Project3) 以及文件系统 (Project4)。所有的 Project 都给学生留有很大的设计空间，总代码量在 2000 行左右。根据 Stanford 学生<a href=https://www.quora.com/What-is-it-like-to-take-CS-140-Operating-Systems-at-Stanford>自己的反馈</a>，在 3-4 人组队的情况下，后两个 Project 的人均耗时也在 40 个小时以上。</p> <p>虽然难度很大，但 Stanford, Berkeley, JHU 等多所美国顶尖名校的操统课程均采用了 Pintos。如果你真的对操作系统很感兴趣，Pintos 会极大地提高你编写和 debug 底层系统代码的能力。在本科阶段，能自己设计、实现并 debug 一个大型系统，是一段非常珍贵的经历。</p> <p>北大 2022 年春季学期的操作系统实验班也将会首次引入 Pintos 作为课程 Project。我和该课程的<a href=https://github.com/AlfredThiel>另一位助教</a>整理并完善了 Pintos 的<a href=https://alfredthiel.gitbook.io/pintosbook/ >实验文档</a>，并利用 Docker 配置了跨平台的实验环境，想自学的同学可以按文档自行学习。在毕业前的最后一个学期，希望能用这样的尝试，让更多人爱上系统领域，为国内的系统研究添砖加瓦。</p> <h2 id=_2>课程资源</h2> <ul> <li>课程网站：<a href=https://cs162.org/ >https://cs162.org/</a></li> <li>课程视频：<a

Project，为了防止代码抄袭，我的代码实现没有开源。</p> <hr> <div class=md-source-date> <small> 最后更新: <span class="git-revision-date-localized-plugin git-revision-date-localized-plugin-date">May 11, 2022</span> </small>
