Destin of Smarter Every Day goes behind the scenes at the 23andMe lab to show how genotyping works. He also discusses DNA testing and privacy.

Will Wilson of FoundationDB explains how the team tested their distributed database using deterministic simulation. By running the whole system in a simulator with injected faults and reproducible seeds, they could find rare concurrency and network bugs.

Gary Bernhardt's RubyConf 2012 talk on testing in isolation without mocking everything. It goes through behavior versus data, mutation versus immutability, and how a functional core with an imperative shell yields natural isolation and parallelism.

Robert Miles explains the orthogonality thesis: how an agent can be highly intelligent while pursuing goals that seem stupid or alien to humans. He separates intelligence from goals and touches on the stamp-collector example.

Deviant Ollam, head of a physical penetration testing team, presents tactics for getting into buildings, from bypassing door levers with a wire to defeating bank doors. He argues that physical security is often surprisingly weak.

Lex Fridman interviews Jeff Hawkins, founder of Numenta and author of On Intelligence, about the Thousand Brains Theory and reverse-engineering the neocortex. They also cover Hierarchical Temporal Memory and brain-inspired AI architectures.

MedCram's Dr. Roger Seheult summarizes a discussion with Dr. Michael Mina on cheap, paper-based at-home COVID-19 antigen tests. It explains why lower sensitivity can still work well for screening infectious people.

The full 1973 BBC Lighthill debate on artificial intelligence, featuring James Lighthill, Donald Michie, Richard Gregory and John McCarthy. It documents the argument that preceded the 1970s AI winter and includes early robot demos.

Raymond Hettinger's PyBay 2018 keynote on preventing, finding and fixing bugs under a time budget. He covers testing practice, type annotation tradeoffs and the limits of coverage metrics.

GreatScott! tests ProLogium lithium ceramic batteries, a solid-state design. He measures their volumetric and gravimetric energy density, compares them to Li-ion and LiPo, and runs durability tests at the end.

A short 2019 clip of Chuck Schumer's January 2017 warning to Trump that the intelligence community has many ways of getting back at him.

John Oliver's Last Week Tonight segment on standardized testing in American schools. It covers how tests drive school funding, the achievement gap, and the testing industry around companies like Pearson.

A 2018 lecture, with subtitles available, by former Finnish intelligence colonel Martti J. Kari on Russian strategic culture. He walks through the historical layers of Russia and explains why the country behaves as it does.

A long Team House podcast interview with James Lawler, a former CIA operations officer who led counterproliferation work against the A.Q. Khan nuclear network. He discusses HUMINT, WMD and how such operations were run.

Isao Hashimoto's time-lapse map shows all 2053 nuclear explosions between 1945 and 1998, with each nation getting a blip and a running tally. Each second represents one month.

A dramatized fictional video of micro drones with facial recognition and swarm AI used as autonomous killer weapons. It is a Slaughterbots-style warning about lethal autonomous weapons.

Scott Manley tells the story of a computerized telemetry system built to sit at the heart of a nuclear test device in place of the plutonium pit, designed to transmit data in the microseconds before it was destroyed.

J. B. Rainsberger argues that large integrated tests are a scam: they are slow, fail opaquely, and give a false sense of coverage. He advocates focused collaboration and contract tests at boundaries instead.

A one-minute clip of a crow repeatedly sliding down a snowy roof on a small lid, apparently just for fun.

Misko Hevery's Clean Code Talk shows how to use object-oriented techniques such as polymorphism to remove repeated if and switch statements. The result is code that is easier to test, understand and maintain.

A Jordan Peterson university lecture on the Big Five trait openness to experience, covering creativity and intelligence. It explains how IQ is measured, how well it predicts life success, and the Pareto distribution of creative output.

Developmental and synthetic biologist Michael Levin speaks at a Harvard Extension student event on bioelectricity, body intelligence and regenerative medicine. He discusses how cell electrical networks guide growth and form.

Andrew Ng speaks at the Stanford MSx Future Forum about how AI is transforming industry after industry, comparing its impact to electricity. The talk also touches on evil-AI worries, jobs and basic income.

Builder Matt Risinger freezes water-filled copper and PEX piping capped with SharkBite fittings to see which survives. The video compares how each pipe type handles freezing.

An excerpt of Richard Feynman's 1985 lecture Q&A about whether machines can think. He discusses the difficulty of defining what computers can never do and compares machine intelligence to machines that don't copy animals.

A panel from the Beneficial AI 2017 conference moderated by Max Tegmark, with Elon Musk, Stuart Russell, Kurzweil, Hassabis, Harris, Bostrom, Chalmers and others. They discuss likely outcomes of human-level AGI and what outcomes are desirable.

A timeline visualization plotting the 2053 nuclear tests and detonations from 1945 to 1998 on a world map, with sound marking each blast. It conveys the pace of the nuclear arms race.
