The slides for each Inf1-DA lecture are available in advance from the Lectures web page. On the day of the lecture you’ll see them marked “(Handout)” as that’s the version in the 3-up printed sheets. After the lecture itself I put up a blog post with a copy of the slides as displayed — sometimes that has a few more bits and pieces included.
Sometimes this means the page changes faster than web and browser caches expect: if you can’t get the slides for the day, try refreshing.
