Technology Connections explains how dishwashers work and how to use them well, including detergent use, the prewash cycle and why pre-rinsing hurts. It follows his earlier dishwasher videos.

A New York Times Opinion documentary tracing Soviet and KGB disinformation, from the 1980s AIDS origin hoax to modern campaigns like Pizzagate. It features former KGB officers and the people who tried to counter the lies.

Will Wilson explains autonomous testing: using deterministic simulation and fuzzing, building on FoundationDB's approach, to test software continuously. It sets out the ideas behind his later company Antithesis.

Raph Koster's 2014 GDC Next talk on what science says about creativity, with practical steps game designers and developers can use to be more creative. It frames creativity as applying existing patterns in new contexts.

The Center for Election Science explains favorite betrayal in instant-runoff voting: in some elections, ranking your favorite first can cause your least favorite to win. It contrasts this with plurality voting's spoiler problem.

A New York Times Op-Docs short in which actors perform a real legal deposition transcript. A lawyer gets tangled in an absurd argument with a county employee about what counts as a photocopier, in a dispute over fees for public records.

A visualization and sonification of 15 sorting algorithms, from selection sort to bogo sort, run on shuffled integers in six minutes. Each algorithm gets a size and speed scaled to its complexity.

Historian Timothy Snyder explains the politics of inevitability and the politics of eternity, two ways of thinking about time that frame his books On Tyranny and The Road to Unfreedom.

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.

GDC 2019 session where Insomniac's David Santiago describes the procedural systems used to build Manhattan for Marvel's Spider-Man. It covers the open-world pipeline and how each system was designed to support iteration and dependencies.

Daniel Dennett gives a Royal Institution talk toward a unified theory of information, tying together evolution, learning and engineering. He argues that design can arise bottom-up through small steps without a designer.

Christopher Domas's REcon 2013 talk on dynamic binary visualization for reverse engineering. He shows how rendering binary data as interactive visual maps and trigraphs reveals structure that hex dumps hide, leading to his Cantor.dust tool.

Alan Kay visits Carnegie Mellon's School of Computer Science in 2007 for an informal conversation with faculty and students. He discusses the state of CS education and criticizes mainstream computing.

Primitive Technology shows building a cord drill from scratch and then upgrading it to a pump drill, using only primitive materials like a stone flywheel and cord.

PBS Space Time explains Stephen Hawking's prediction of Hawking radiation and how black holes can emit radiation and slowly evaporate. It goes beyond the common particle-antiparticle analogy.

Wendover Productions explains how UK rail privatization worked and why it failed. It covers the fragmented operator and infrastructure structure and why market forces apply poorly to rail.
