A parody interview with a fanatical Vim user, mocking editor-loyalty culture. It is a short programmer-humor sketch from Kai Lentit.

Not Just Bikes explains Dutch bicycle-only roads, which let people travel long distances in and out of cities with almost no car interaction. It shows how this changes cycling from a chore into something enjoyable.

An Onion News Network satirical segment about a memorial dedicated to the future victims of a dam that officials know will fail. It is a dark joke about known infrastructure risk and inaction.

Casey Muratori captures CygnusEd Professional running on an Amiga 2000, showing how smoothly it scrolled text. He notes the real effect is better on a period CRT.

Isaac Arthur examines Dyson spheres and swarms, including common myths and misconceptions. He covers uses such as interstellar travel, black hole generation, and computing large enough to simulate universes.

The first lecture of MIT's 1986 6.001 Structure and Interpretation of Computer Programs, given by Harold Abelson, introducing Lisp and the idea of computer science as the study of process.
