https://github.com/nleak/nleak 给 Adobe 做了一学期的 NodeJS memory debugging tool 刚刚开源啦~ NLeak 可以自动 take heap snapshots, 对比前后 Heap Graph 来找到 memory leak,然后用 JS rewriting 和 instrumentation 来找到 source code 里的 leaking source 位置,同时能找到 closure 里的 leaking。目前 PoC 跑了简单几个文件,理论上可以对很大型的 NodeJS 项目找到对应的 memory leak,已经交付给 Adobe 未来可能会继续作为开源项目来迭代,let's see how it goes! #nodejs #memoryleak #debug #Adobe #CMU

https://15445.courses.cs.cmu.edu/fall2023/ 开始了,和往年一样 Andy Pavlo 开始实时上传所有课程到 YouTube,开放了 Gradescope autograder 给 nonCMU students。下半年在工作之余,想跟完这门课的 project,但没时间跟不完也没有关系,完全对 system development 兴趣驱动来学习 no pressure。建了个 tg study group 来跟进进度和讨论 projects,感兴趣的朋友可以加 https://t.me/+4_BPUnszKzM4MTg1 #CMU #DB #15445
