I'll let them look it up (though hopefully everything they need is in the sentence).

I have 1H45/week, but I only want a fraction of that to be the lecture, and the rest of the time I want them to be reading through again and trying what I showed (I feel that most of the time should be them trying stuff, not me telling them stuff) and then asking questions. So what I really want is ~45 min max for the lecture component. Also, today is the first lecture, and some student have never used linux, etc. so it's going to be a challenging start to cover all this :)
