Depends on who your professor was. I worked as an engineering lecturer for a few years. I told my students that having a reference text can be invaluable as you move through your career. For certain kinds of engineering, this is absolutely true. Paper reference texts have little long-term value in computer engineering. But civil or mechanical engineering? The principles of material strength do not change. And that’s the kind of engineering I teach. So I really encourage students to get paper reference texts.
To facilitate this, I would always post homeworks that included scans of the full problems. I either wrote the problems from scratch or cut out problems from the textbook. I then told students to still buy the book, but buy a few editions back to get their reference text for a song. I still want my students to have a permanent physical book, but if you design your course right, they won’t need the newest edition.
I think the bigger concern is someone uploading CP to it and then maybe having your house raided by the cops. Even if you completely separate your personal files from the lemmy server, the police are just going to seize every computer in the house. And the fact will remain that they found CP on your computer. The burden of proof then falls on you to prove that it wasn’t you who put it there.
