A course on building a programming language, taught as a live class by Roberto (likely Roberto Ierusalimschy, the Lua designer, though the comment does not name him in full). Commenters describe it as a course where the design principles behind Lua are discussed.

One commenter calls it Roberto's awesome course and recounts asking the instructor in a live class about Lua's design philosophy of being lightweight, effective and simple.

   I took Roberto's awesome "Building a Programming Language" course in 2022 and during a live class I had the opportunity to ask why they don't incorporate more stuff into the language. He said that it was designed to be lightweight, effective and simple. Anything that goes against those principles should not be integrated into Lua's codebase.
