July 1, 2023 was the (known in advance) effective date of the reddit API change that killed 3rd party apps. Not really too surprising a bunch of apps for Lemmy started development leading up to that change in order to try to establish a userbase among the refugees. I was one of those refugees.
Another laziness by the professors is using book questions instead of just writing their own.
When I taught I told my students that the book was a resource for studying the material from a different perspective than the one I gave in lectures. Not actually required for the course even though I didn’t have control over it being listed as required on the course listing. And I told them if they wanted to get it, they should find the cheapest copy they could. I’ve heard you can sometimes find very cheap electronic copies (wink wink).
It is funny to see the questions you write end up on Chegg though.
