An 11-minute animated introduction to P vs. NP and the wider landscape of complexity classes, inspired by the Complexity Zoo wiki. It assumes no background in computer science.

A PBS Infinite Series episode explaining the mathematics of quantum computers, including how qubits store complex numbers and how quantum computation differs from classical computation. Hosted by Kelsey Houston-Edwards.

An Every Frame a Painting video essay analysing how Edgar Wright creates visual comedy through framing, camera movement, editing, sound effects and music.

Dave Ackley gives a high-level introduction to robust-first computing, which prioritizes robustness over efficiency in computer architecture. A sorting demo illustrates the idea.

Sabine Hossenfelder asks whether complex numbers are just a convenient tool or necessary in physics. She discusses a recent paper arguing that quantum mechanics cannot be done with real numbers alone.

Admiral William McRaven's 2014 University of Texas commencement address, built around lessons from Navy SEAL training. It famously opens with the case for making your bed every morning.

The opening episode of Ted Nelson's Computers for Cynics series, in which he casts doubt on conventional accounts of computer basics. He argues that conventions and packaging are mistaken for technology.

A 1973 AT&T training film made for new employees at Bell Labs' Holmdel Computing Center, when Unix was in its third version and running at 16 computer centers in the Bell System. It shows how users submitted jobs and used the center's machines.

A short clip of Stephen Fry explaining the differences between American and British comedy. He attributes them to cultural attitudes such as optimism versus pessimism.

IBM's Dr. Talia Gershon explains quantum computing to five people of increasing expertise: a child, teen, college student, grad student and professional. The WIRED series format moves from simple analogies to technical detail.

Robert Scoble interviews Paul Graham at Y Combinator's Mountain View headquarters as 36 new startups debut. They discuss what YC is, and Graham's no-assholes rule.

Ted Nelson, in his Computers for Cynics series, gives a critical history of Xerox PARC's vision of personal computing. He lists what he sees as the limitations and wrong turns in PARC's approach to the desktop and documents.

An Asianometry explainer on why the Soviet Union, once a leading computing power, fell far behind the US in computers by the 1980s. It traces the gap from the 1960s onward despite strong state support for science.

A 1969 BBC Tomorrow's World segment about Nellie, a school computer used by pupils at Forest Grammar School to solve equations and play music. Students learn programming and maintenance, and act out binary arithmetic.

A five-minute demo of the Common Lisp debugger fixing a bug, recompiling a single function, and resuming execution from the failed stack frame. It shows how to avoid re-running long computations.

Not Just Bikes examines Toronto's GO Transit commuter rail, arguing it is a costly system with park-and-ride stations and rush-hour-only service that subsidizes car-dependent suburbs.

An excerpt from Hal Abelson's opening SICP lecture introducing computer science and contrasting declarative and imperative knowledge. He argues that computer science is not really a science and is more like magic or engineering of ideas.

FortNine argues that the US DOT motorcycle helmet standard (FMVSS 218) is badly outdated and weak. It compares it with Snell and ECE standards and points to where you can look up test reports for your own helmet.

An SNL sketch in which Nick Burns, the condescending IT guy, trains a new tech support hire to mock users over simple computer problems.

Tom Scott explains for Computerphile why electronic voting is a bad idea, arguing that paper ballots are transparent, auditable and hard to tamper with at scale. He covers why moving voting to phones, tablets or computers undermines trust and verifiability.

A Computerphile video in which Dr Mike Pound and PhD student Lewis Stuart explain 3D Gaussian splatting, a quick technique that turns photos of a scene into a 3D model without much compute. It includes a demo and compares the approach to NeRFs.

Tom Scott explains for Computerphile how floating point numbers work, why moving the binary point is fast, and why it handles money badly.

A Computer History Museum demonstration with Dan Ingalls of Smalltalk-76 running on a Xerox Alto, recorded in 2017. He shows the live environment and discusses the system.

Tom Murphy's satirical SIGBOVIK 2007 presentation, delivered under a pseudonym, proving that generalized Super Mario Bros. is NP-complete. It is a short, deadpan take on a complexity theory result.

Tom Scott explains for Computerphile why handling time and timezones in code is so hard, walking through a simple web app that computes how long ago something happened. It covers the quirks of timezones and calendars and ends in an exasperated rant.

Tom Scott explains for Computerphile how Unicode and UTF-8 grew out of messy older character encodings to become the web's standard. It covers why the design works and how it handles worldwide text.

A nine-minute Stewart Lee stand-up routine about political correctness and the claim that it has gone mad. It is dry, layered British comedy that takes the complaint apart.

A short Yes Minister clip in which Sir Humphrey explains why a hospital with no patients still needs a large administrative staff. It is a satirical look at bureaucratic bloat in the public sector.

Computerphile interview with Prof. Ross Anderson on how Chip and PIN payment systems are being compromised, and the attacks researchers have seen.

A Computerphile video in which Mark Jago of the University of Nottingham explains Turing's halting problem and how it led to the blueprint for the modern computer.

Computerphile video in which Mike Pound explains a University of Maryland paper on watermarking LLM output. The method biases token choices so generated text can later be detected statistically.

Professor Brailsford of the University of Nottingham describes how the university set out to print its own mathematics exam papers in the 1980s. The story centers on getting a Mergenthaler Linotron 202 typesetter to work with their own software.

Steve Jobs's 2005 Stanford commencement address, built around three stories: connecting the dots, love and loss including being fired from Apple, and death. It is a 15-minute talk on finding work you love.
