The first episode of James Burke's Connections series, 'The Trigger Effect', explores how modern society depends on interlinked technological systems and how quickly it breaks down when they fail, starting with a power blackout.

A 24-hour loop of Star Trek TNG starship engine ambience, meant as background sound for relaxing, sleeping or concentrating.

Rhonda Patrick of FoundMyFitness makes a case for isothiocyanates such as sulforaphane from cruciferous vegetables and broccoli sprouts. It covers cancer, aging, heart disease, brain and behavior, and neurodegeneration, with chapter timestamps.

Corridor Crew VFX artists react to the visual effects of the 2021 Dune and compare them with David Lynch's 1984 version. They discuss which effects were practical and which were CGI.

A 1983 behind-the-scenes film about making the HBO 'Feature Presentation' starship logo sequence. It shows the handcrafted miniature city, motion-control cameras and practical effects.

A Financial Times film examining how Brexit hurt the UK economy, with FT writers and business people. It looks at trade effects, political silence about the costs, and the absence of a convincing Brexit dividend.

The first part of a ShaderToy live-coding series that lays the groundwork for The Drive Home, a rainy night-traffic shader. It covers basic setup and builds toward rain and bokeh effects.

A short clip of Simon Peyton Jones talking about the future of programming languages, saying Haskell is useless in the sense that pure programs cannot have effects, while mainstream languages are useful but unsafe. He describes languages converging, with ideas such as STM and LINQ moving between them.

Corridor Crew dive into the visual effects of Terminator 2 and try recreating the T-1000 bars scene with modern tools. They explain how the original effects were achieved.
