Thank you to OP for posting. Is there a place, besides HN, where I can find more like this? I am interested particularly in that it is about theory of computation and in the fact that it is detailed and substantive, as contrasted with introductory class lectures for sophomores.
(I am aware of the ToC blog feed http://cstheory-feed.org/, which is also a good source to keep an eye on.)
Ron Pressler (the presenter) is an active contributor to HN [1], and he blogs at blogs at https://pron.github.io [2]. There he has a multi-part blog post under the same name as the presentation, and if he chimes in here, he may be able to provide ptrs to additional resources (else ping him on Twitter [3]).
