Computability & complexity theory Videos Recommended on Hacker News (34)

Computability & complexity theory is one of the 150 topics Hacker News readers organize their video recommendations around. These 34 videos each earned real recommendations in real HN threads between 2008 and 2026 — 131 recommendations in total — and they're ranked by how many separate months the community kept coming back to them, not by view count.

Theory of computation: Turing machines, halting problem, P vs NP, complexity classes, lambda calculus, automata, Church-Turing, Goedel incompleteness, computability.

Why HN keeps sending people here — on Ruby Conf 12 - Y Not- Adventures in Functional Programming by Jim Weirich: “perhaps the most entertaining and interesting technical talk I've ever seen.” — an HN commenter, 2015.
