The Liskov & Gutka PDF link returns a 404 :-(
This was an instance of Google brokenness, as PDFs don’t offer a place to copy the URL from, and I messed it when removing the encoding from google’s result page.
The one I post is from the 6170 course at MIT, it can be found at opencourseware.
On unrelated news, I think I have the POST and PUT use for Mutators wrong. I need to check it and edit, when I finish the September exams rush here.
