I did look closely at this list. I commented because it's such a typical example of unearned upvote candy. I could have assembled this list (as a non-computer scientist) in less than an hour just by looking at the usual places I look for lecture notes and following the typical linkbait-maker advice of leaving a brief comment and headings. The author admits s/he is still working through the material and the details on…
Ok, I should have renamed it from the original title given by the author to "Excellent List of Distributed Systems and Relevant CS Courses With Good Lecture Notes, Assembled by a University of Cambridge PhD in Mobile Distributed Systems, Zookeeper Committer and a Glorious Systems Engineer Who Lives and Breathes Distributed Systems at Cloudera" to get less upvotes.

I have very little respect for Quora, HN, retweets, or bookmarks which are accomplished with a click.

Cheers, thank you for the rational back-and-forth.
