Super Eyepatch Wolf analyzes why The Simpsons declined after its golden age, pointing to changes in the writers' room and a shift in the style and complexity of its comedy.

Mathologer shows how times table diagrams on a circle produce cardioids and other curves connected to the Mandelbrot set. He explains the patterns and links to a tool for making your own diagrams.

Hennessy and Patterson's 2018 Turing Award lecture at ISCA, A New Golden Age for Computer Architecture. It covers domain-specific hardware, security, open instruction sets and agile chip development.

A 60fps capture of Future Crew's 1993 MS-DOS demo Second Reality, one of the best-known pieces of the demoscene. It runs about 16 minutes of real-time graphics and music effects on PC hardware of the era.

A short animation reconstructing a planet's looping orbit using Ptolemy's epicycles and deferents, with the epicycles tracing out the face of Homer Simpson. It shows how enough circles can reproduce nearly any shape.

A demo of the 8pen, a gesture-based keyboard replacement for touchscreens that lets users enter text by moving around a circle. It is meant for phones, remotes and game controllers and mimics handwriting.

Micah Lee's Circle of HOPE 2018 talk on Qubes OS, which isolates activities in separate virtual machines so one compromise, such as a bad PDF or USB stick, does not expose everything. He gives an overview timed around the Qubes 4.0 release.

Robert Llewellyn of Fully Charged takes an early, 19-minute test drive of the Honda e electric car in Frankfurt. He looks at its acceleration, camera wing mirrors and tight turning circle.

Jaron Lanier delivers the 2018 Willy Brandt Lecture in Berlin on who civilization is for, covering data, AI, tech platforms and the economics of who benefits, followed by a Q&A with Germany's data protection commissioner Ulrich Kelber.

Numberphile with Daniel Erman on the Josephus problem, where people in a circle are eliminated in turn. It shows how the survivor's position follows a neat pattern tied to powers of two and binary.

"Nuggets" is a five-minute animated short by Andreas Hykade in which a kiwi bird tastes a golden nugget and keeps chasing the high. It works as a parable about addiction, habituation and withdrawal.

A 3Blue1Brown live lockdown math episode asking what Euler's formula e^(pi i) is actually saying. It builds intuition through exponentials, rotation and vectors landing on the unit circle.

Chandler Carruth's CppNow 2023 talk describes Carbon as a successor language to C++ rather than a superset, focusing on C++ interop and a path to memory safety in large existing codebases. It explains why Carbon takes a different approach from Cpp2 and Circle.

A two-minute remix-style video set to Hall of the Mountain King that mocks Anthony Fauci's Covid pandemic statements. It circulated widely among vaccine and mandate skeptics.
