There is a set of lecture notes I would like to work through the exercises very carefully. Instead of having thousands of scrap pages lying around my desk - I considered typing them up on and posting them on GitHub.
Will this make the textbook unususable for future courses based on that text?
I found this related question: Is it good to have solutions of homework published? which argues the solutions are beneficial check on the validity of the text.
However I am not the teacher, I am the student. Having them online is for my own pedagogical benefit and to share with specific other people.
