操作系统：三个简单部分
Operating Systems: Three Easy Pieces
2014 — 2021，它一次次回到首页
黑点是上首页（≥ 50 分）的那次投稿，空心点是没冲上去的投稿，点越大分数越高。
导读
《Operating Systems: Three Easy Pieces》(OSTEP) 是威斯康星大学 Remzi 与 Andrea Arpaci-Dusseau 夫妇编写的免费开源操作系统教材，围绕虚拟化、并发和持久性三大主题展开。全书章节短小精悍、行文风趣，被广泛认为是学习操作系统基础的最佳入门资源之一。
为什么经久不衰：它免费、易读且质量极高，多年来反复登上 HN 首页，无论是科班学生还是自学程序员都能从中系统补齐操作系统知识。

作者是最优秀的教授，本书是极佳的免费 OS 入门资源
我在 UW 上过 Remzi 的两门课，其中一门就是操作系统。他是我遇到过的最好的教授，这本书是学习操作系统基础的绝佳工具。读起来很快，我推荐给所有想找免费操作系统入门资源的人。

I had Remzi for two courses at UW, one of them being Operating Systems. He's the best professor I've ever had, and this book is an amazing tool for learning the basics of an Operating System. It's a quick read, and I would recommend it to anyone looking for a free Intro to OS resource.
即使资深工程师读它也大有收获
我读本科时这本书还没写出来。但今年我发现了它并通读了一遍。即使已有 20 年专业软件开发经验，这本书对我自以为很熟悉的话题的颠覆仍令我惊讶！我还觉得这本书由一对夫妇合著很有魅力。

This book hadn’t been written yet when I was in undergrad. But this year, I found it and worked through it. Even with 20 years writing software professionally under my belt, the ways this book shifted my perceptions on topics I assumed I knew well was surprising! I also find it charming that the book is co-authored by a married couple.
章节短小易读，特别适合自学者串联知识
强烈推荐这本书。章节都很短小，相比恐龙书，开始读一章后更容易读完。并发那几章让我多次发出“原来 XXX 是这么工作的”的感叹。每章末尾的参考文献也满是珍宝。我是自学 CS 的，知识体系里有很多空洞，这本书帮我把很多点连了起来。

I highly recommend this book. The chapters were "bite sized". Compared with the dinosaur book, it was easier to finish one chapter after I started on it. The chapters on concurrency made me cry with "so this is how XXX works" a lot. I also found the references near the end of each chapter were full of gems. I self-taught CS, so not surprisingly there were lots of "void" and "dots" in my knowledge space. This book connected lots of dots together.
与昂贵的恐龙书相比毫不逊色，但希望有更完整的开源实践项目
我用过/教过“恐龙书”，就其价格而言相当糟糕。它是个不错的概览，但有不少问题：CPU 调度部分既稀疏又混乱。我翻了翻这本书，感觉水平相当。不过这本书没讲速率单调调度和最早截止时间优先。我真希望有开源项目带开发者或学生从头到尾写一个操作系统，而且要易于理解——我知道 xv6，但觉得它太复杂了。

I've learned/taught from the "dinosaur book" [1] and for the price tag it's pretty bad. It's a nice overview but it has several problems. First of all the section on CPU scheduling is pretty sparse and confusing. I skimmed through this book and it seems on par. But the one thing this book skips is Rate monotonic and Earliest deadline first - which I found to be rather difficult algorithms. This is because whenever you would research it - I would find other professors using screenshots from the dinosaur book that doesn't help explain it at all. I would be happy to give you my notes on it. I really wish that was a an open source project that took developers and/or students from start to finish of an operating system. I should preface that and say that it should be easy to understand and use. I know about xv6 and I feel like that's too complex. I've found MikeOS [2] but I will have to study/extract it into pieces. In any case - I really think this practice should be more widespread. Unfortunately, I've found many people to offer "lazy criticism" they point out something is wrong but don't want to offer any help to make it better. The Rooks Guide to C++ is a perfect example of this - yeah it's not perfect and doesn't contain all C++ knowledge you could ever know about (there have been a lot of negative criticism about the book). But that's not the point - it's designed for people who know nothing about programming to learn about C++ in a 16 week course. It's goal isn't to replace the Stroustrup expert C++ book.
