Vsauce's roughly 24 minute explainer on the Banach-Tarski paradox, building from infinity and set theory to the decomposition of a sphere into pieces that form two spheres.

3Blue1Brown explains space-filling curves and the Hilbert curve, and how infinite mathematical constructions connect to finite, practical approximations. It touches on mapping between dimensions and sensory ideas.

A bot built by Robin Baumgarten plays Infinite Mario using A* path-finding, shown as a red planned path that updates as new obstacles appear. It won the Mario AI competitions and uses only on-screen information.

Jordan Hubbard, FreeBSD co-founder, discusses where FreeBSD might go over the next decade at MeetBSD California 2014. He draws on his Apple Unix experience, including bringing launchd-style init ideas to FreeBSD.

A very short clip from The Matrix Reloaded in which Trinity runs nmap and then uses an SSH exploit. The scene is notable for showing a real tool.

FreeBSD developer Benno Rice traces the history of init and bootstrap systems at linux.conf.au 2019 to explain why systemd was seen as necessary and why it provokes such strong reactions. He also discusses why change is scary.

Casey Muratori argues against smart pointers and RAII, advocating grouped-element thinking, zero-is-initialization and stubs as better ways to structure memory and handle errors.

Mathologer examines how identities like 1+2+3+... = -1/12 arise in Ramanujan's work, starting from his 1913 letter to Hardy. The video explains the rules for summing infinite series and why such results are meaningful but not naive sums.

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.

Veritasium explains how Penrose tilings and quasicrystals overturned the belief that 5-fold symmetry and non-periodic crystals were impossible, including an interview with Paul Steinhardt.

Veritasium explains why the kilogram is being redefined in terms of Planck's constant rather than a physical metal artifact. It visits NIST to show the Kibble balance and why measuring mass precisely is hard.

NativLang's 47-minute animated documentary traces the birth and evolution of writing, from early cave marks to modern scripts. It presents the history of the world's writing systems as a story.

Mathologer uses continued fractions to show why the golden ratio is the most irrational number, comparing it with root 2, e and pi and pointing to where this shows up in nature.

Lex Fridman interviews physicist Roger Penrose on consciousness, the limits of computation, quantum mechanics and his cyclic cosmology. It covers his views on AI and the big bang.

Dave Ackley presents robust-first computing and the ULAM programming language for the Movable Feast Machine, a cellular-automata-like architecture. It was a short video for the Future Programming Workshop 2015.

Steve Jobs's 2005 Stanford commencement address, in which he tells three stories about connecting the dots, love and loss, and death, including his remarks on typography.

John A. De Goes's Scalapeno keynote argues that Scala's popularity is declining because of compile times, complexity and compatibility problems. He proposes a path for Scala to survive, including a simplified functional subset.

Stand-up Maths explains why the perimeter of an ellipse has no simple closed-form equation, showing the infinite series and presenting approximation formulas.

A video essay from Pop Culture Detective arguing that The Big Bang Theory normalizes sexism and toxic masculinity through its portrayal of nerd men. It analyzes recurring tropes in how the male leads treat women.

Stuart Halloway argues that simplicity is objective, with a definition and etymology useful to programmers, rather than a subjective buzzword. He shows how this view informs Clojure's design and how to make programs simpler.

An hour-long, carefully sourced video essay from Ahoy asking what counts as a video game and which one was truly first. It examines Tennis for Two, Spacewar, Pong, the Brown Box and a 1947 CRT device.
