This Project includes the Lec record and Lab implementation for 6.824 Schedule: Spring 2020 .
The MIT 6.824 is a very amazing course, even after working for five years, a lot of content is still worth learning.
I change the project implementation to go 1.17 (the original project on the website is for go 1.13).
The directory of this repositories:
The Reading Records are in BookReading Project
lab link: http://nil.csail.mit.edu/6.824/2020/labs/lab-mr.html
change the test-mr.sh and file location to adapt to go1.17
run test:
cd project/src/test
./test-mr.sh
