The UK DVSA's one-minute guide to the hazard perception part of the driving theory test, covering when to click and how to score well.

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.

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.

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 VICE News segment following Uber driver Terri White, who drives 83 miles from Stockton to San Francisco and sleeps in her car between rush hours. It looks at the conditions of gig-economy drivers.

A short clip of Gary Johnson being booed at a Libertarian Party debate for saying he supports driver's licenses.

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.

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.

FortNine's tongue-in-cheek guide to why drivers fail to see motorcyclists and how riders can make themselves more visible. It touches on perception psychology, including the role of saccades.

A doctor from Medlife Crisis explains in under three minutes why even a rich patient should not simply order every medical test, touching on pre-test probability and Bayesian reasoning. False positives make blanket testing counterproductive.

An English-subtitled German workplace safety film about forklift driver Klaus. It is campy and darkly comic, staging an escalating series of forklift accidents.

An animated National Film Board of Canada short about a young woman who picks a log driver as her partner because his work makes him a great dancer. It is set to Wade Hemsworth's folk song sung by Kate and Anna McGarrigle.

A Fifth Gear segment in which Tiff Needell tests autonomous emergency braking systems in the Mercedes S Class, Volvo V40 and VW up!. The cars are driven toward an inflatable dummy car to see how each system performs.

A very short clip of George Carlin's bit on idiots and maniacs, about the other drivers on the road.

Dashcam footage of a Tesla Model S on adaptive cruise control hitting a stopped van, with the driver listing the safety systems that failed to react. The uploader still calls the Model S the best car in the world.

Ian Cooper's DevTernity talk revisits Kent Beck's original TDD ideas and shows where misunderstandings crept in. It argues tests should target behaviors through public interfaces rather than implementation details, so suites support refactoring instead of resisting it.

Gil Tene of Azul Systems explains common pitfalls in measuring latency and response time, including why averages mislead and the problem of coordinated omission. He introduces open source tools like HdrHistogram for better measurement and reporting.

SQLite creator Richard Hipp gives a history of SQLite and explains where it shines as a database at the edge of the network with no DBA. He covers long-term support, testing and how it is used in products.

America's Test Kitchen tests eight carbon-steel skillets to find the best one, asking whether a single pan can replace stainless, cast iron and nonstick. It names a winner and covers how the pans perform.

Adam Neely tests the claims for tuning to A=432 Hz by trying the unusual tuning systems that its proponents' numerology requires. He compares how they sound against standard tuning and temperaments.

Part one of a 1996 BBC Modern Times documentary on the training to become a London black cab driver. It follows candidates learning the Knowledge and facing stressful repeated exams with Public Carriage Office examiners.

A short video of a Boeing 777 wing being tested to destruction, finally breaking at 154 percent of its designed limit load. The wing is flexed upward until it fails.

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.

Veritasium's Derek Muller spends an hour in a silent, dark anechoic chamber at BYU to test the claim that 45 minutes is the most anyone can bear. He reports on his experience and other people's reactions.

A Thoughtworks conversation among Martin Fowler, Kent Beck and David Heinemeier Hansson on whether TDD is dead. They discuss the tradeoffs of test-driven development, mocking and where TDD helps or hurts design.

Jim Coplien and Bob Martin debate test-driven development and unit testing in an InfoQ video that grew out of a JAOO 2007 dispute. They also touch on design and architecture.

An English-subtitled version of Staplerfahrer Klaus, a gory dark-comedy German workplace safety film about the dangers of forklifts in warehouses.
