The lab manual is home-grown and a work in progress. We always are finding things to improve. So please don't get agitated when the exercise you do does not exactly match the description in the manual. It is NOT a good idea to print off the entire manual. There are certainly little changes that will occur throughout the term as students or the TAs discover errors or we find something new to try. A good plan is to check the "LATE BREAKING GNUS" for the course. I will try to post information there about changes. So if you see something like "next week's lab has been upgraded", then you should download a new pdf of the lab manual and replace your old copy with the new one. Then print just the exercise for the current week from the new copy. Enjoy the course! =RZ=
