I've been turning my brain into jello by spending about four hours every day writing exercises to go along with Learning Perl. It's surprisingly tough to come up with something for a student to do when they only have the first two chapters of Learning Perl.
I thought I'd get around the mind-numbing boredom of writing Perl programs using only scalars by working from both ends of the book, but after a couple days of that, I've completely lost track of what the students know. I may have just done some exercises for chapter 16, where they can use sort() because they saw it in chapter 15, but then I flip back to chapter 10 and completely mess myself up by using more than they should have seen. I ended up re-writing a lot of exercises for regular expressions because I forgot that the
Randal estimates that it takes him one full work day to create one printed page. I think I'm trying to do double that to meet the deadline. Two more days and this will all be over. I'm not sure how many pages this thing is because I don't think MS Word (not my choice) is paginating correctly. It's been the same page count for a couple of days.
No matter, after this it's all POD writing for the next month on the next big writing project.
