Brian Lonsdorf explains why Underscore.js falls short as a functional programming library, then introduces currying, composition and point-free style in JavaScript. He argues for data-last argument ordering.

A short animated simulation comparing how Multics and Unix were developed, showing why Unix's small composable programs and pipes gave it a efficiency advantage. It frames Unix as a moonshot achievable by a small team.

Mark Seemann argues that functional programming naturally yields many of the best practices object-oriented developers learn painfully. He shows how functional architecture leads to a pit of success, with a pure core and impure shell.

A clip from Attenborough's Life of Mammals following a San tribesman in the Kalahari on an eight-hour persistence hunt, running down a kudu through harsh heat. It shows tracking, endurance running and the hunter's reaction after the kill.

3Blue1Brown shows how the uncertainty principle arises from Fourier transforms. A wave packet cannot be narrow in both position and frequency, so the principle is a property of waves rather than of measurement.

Irving Finkel of the British Museum lectures at the Royal Institution on the invention and decipherment of cuneiform writing in Mesopotamia, and why it is so hard to translate.

A 1982 AT&T Bell Labs film for students about the Unix system and how it can be used practically. It includes Lorinda Cherry building a talking calculator by piping together Unix commands, and a spell checker made from Unix utilities.

Veritasium explains the effort to redefine the kilogram, which was still defined by a physical artifact, and how a near-perfect silicon sphere from the Avogadro project helps. It also covers the history of the unit's odd naming.

An 11-minute clip of Milton Friedman explaining the incentives of unions and how they affect employment. He argues unions restrict labor supply, raising pay for some workers while hurting low-skill workers.

A Boeing 737 pilot explains the runaway stabilizer checklist, the procedure for stopping unwanted horizontal stabilizer movement such as an MCAS activation on the 737 MAX. He walks through the steps, the trim cutout switches and the jackscrew mechanism, and shows a simulator run including the manual trim wheel effort.

Chandler Carruth's CppCon 2016 talk tries to defuse the heated debate over undefined behavior in C and C++. He explains from the compiler writer's perspective why UB exists and how it enables optimization.

Benno Rice's linux.conf.au 2020 talk asks whether UNIX was the best design we could have had. He looks at what alternatives existed, what was gained and lost, and what could be re-learned, including the limits of treating everything as a file.

Summoning Salt traces the speedrunning history of Mario Kart 64's Choco Mountain track and its famous shortcut, through the successive record holders and discoveries. It carries an epilepsy warning for flickering lights.

Tom Scott argues that grammatical gender is a silly concept and that the singular 'they' is an established gender-neutral pronoun. The description carries later corrections and reflections he added in 2019.

Stephen Kell's Strange Loop talk argues that C and Unix already contain Smalltalk-like dynamism and introspection that can be exposed. He presents his liballocs research on bridging dynamic and compiled languages.

Vladimir Voevodsky's IAS lecture starts from Godel's second incompleteness theorem to explore whether first-order arithmetic could be inconsistent. It motivates his vision of univalent foundations and computer-checked proofs.
