By the way, your article has encouraged me to get the students using issues for eg. homework questions they'd normally email, thanks for that.
Can I ask what initial decisions you had, or what did you reorganize with time?
That's pretty specific to the more or less sequential approach with the book, though. It's a good book, so it can support that kind of thing.
I think it will also help with presenting the supplemental material that is linked with each chapter/section. Again, that might be specific since in the Stevens book, there is always a manpage or Single UNIX Specification reference to give for almost any section.
This might be a good solution if people want something a bit more fancy as a course website. Thanks for sharing.
