https://github.com/PKUFlyingPig/CS186-proj1 作者的这个仓库的初始提交有lahman，拉取后回滚到初始提交版本就好了 |

比如project1的piazza link https://piazza.com/class/kxz3whak4ma3rt 这是对应的getting started页面 https://cs186.gitbook.io/project/assignments/proj1/getting-started |

我测试了最近的版本（sp24）和sp21，sp22，似乎全部的资料都被锁了，只能从flypig大佬的repo里下ppt看了🥲总之备份资料也很重要哇... |

CS186: 这门课程讲得比15445清晰不少，非常适合入门，虽然其前置课是CS61C, 但是实际上和CS61C相关的概念可能只有bit-level interpretation of data和paged memory，反倒是需要学生有很强的数据结构直觉，这是CS61B提供的。它的project是基于simpleDB（mit6.830）开发的，但是要求学生写的代码量不大，很多时候整个类的95%的方法都帮学生写好了，学生只需要理解框架代码然后在合适的时候调用即可。同时project只有本地测试。 CMU15445: 可能是因为15445的prerequisite是大名鼎鼎得15213 CSAPP的缘故，15445很多概念是基于system-level programming来讲的, 所以会抽象不少，特别是Concurrency和Bufferpool部分，讲的会比CS186深入很多。同时其project是基于C++17的，如果只学过CS61B的话会很吃力。它的project是CMU开发的bustub, 有完整的测试框架，代码量和CS186相当。 还有一门是mit6.830, 它的project难度是最高的，代码量也是最高的，因为它要求从底层一点一点实现整个simpleDB数据库，非常推荐在学完上述两节课之后从头做一遍它的projects。我没有系统学过这门课，个人认为其覆盖的内容相当于CS186+CMU15445，难度最高。 COSC 460: 它的lab是基于simpleDB改写的，但是没有CS186改写的那么彻底。 |

哦弄错了是6.5830 |

请问这个推荐度为什么比较低，是因为难吗 |
Beta Was this translation helpful? Give feedback.
-
|
难度是其次，主要是资源不够全，CS186从lecture到discussion到homework到project到exam什么都有。 |

|
能大概说明一下每个lab哪个量级的代码量吗，100行以内？100+？1000+？ |

哥们，我看了下这个课程的project 源文件目前我没找到在哪里获取，因为他官网的指导是要用edstem的社区去看代码链接。我也是第一次看伯克利的课程，如果哥们你有解决的方法，跪求指导 |

放一下proj1和proj6的实现，有空再把rookiedb剩下的两三个proj写完放出来。我顺便放一个lsm-kv（SJTU软工高级数据结构的大作业）原始项目吧，框架并不是很好看戚正伟课也讲的不太行不过董明凯老师的托底工作还不错 |
