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 |
