With respect to homework 4, I think rather than have people struggle with it, with a few things even still somewhat underspecified, I have decided to give you an extra class period to do it, which turns out to mean an extra week. So, I’d like to collect it on the day of the midterm, at the latest. If you are comfortable with it, feel free to hand it in on Thursday, but if you’d like to use the time Thursday to clarify things that aren’t clear about the material on the homework (which is relevant to understanding what we’re doing, and therefore also relevant for the midterm), that’s also fine. I feel that we didn’t get as far as I’d have liked to today.

So, to reiterate: You can hand in homework #4 as late as Thursday October 14 without it counting as coming in late.
