A short clip from Swedish magazine Teknikens Värld showing the 2016 Toyota Hilux nearly tipping over during the evasive-maneuver moose test.

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.

Adam Savage's Tested spends a week with the Magic Leap One developer kit. They dig into the hardware, display technology, user experience and launch apps.

3Blue1Brown explains why positive results on accurate medical tests are often false positives, and reframes Bayes' rule using likelihood ratios (Bayes factors) to update odds. It uses visual examples to make the reasoning intuitive.

Veritasium tells how Kodak film was fogged by radioactive fallout from the first atomic tests, letting the company detect nuclear testing before anyone announced it. The video also covers the deal to keep it quiet and how fallout contaminated packaging.
