That appears to be the Intro to Operating Systems course from the Georgia Tech OMSCS program.

Udacity also hosts the GT Advanced Operating Systems course: https://www.udacity.com/course/advanced-operating-systems--u.... AOS is not a "how to" course, but rather a tour of the challenges operating systems may face (distribution, fault tolerance, scale) and of academic papers attempting to solve them (mostly from the 90s and 00s). As such, the material might not be a good fit for the original post, but this commenter found it fascinating.
