I updated the video lectures page, http://www.ict.kth.se/courses/ID2203/video_lectures.html with the slides that were in the classroom lecture today but that are not in the video lecture.

It is highly recommended that everyone read pages 203-216 in the book (the abstract of ch. 5, and ch. 5.1, 5.2).

As you might have seen there is no video available for lecture 10, which is about Paxos, which will be held tomorrow morning. The slides for lecture 10 are available on the video lectures page though.
