A Technology Connections video on how ground-source (geothermal) heat pumps work and why they hold efficiency in winter. It also covers related heat pump information, and the description notes air-source heat pumps have since improved.

Kirsten Dirksen visits retired mailman Russ Finch in Alliance, Nebraska, who grows oranges, figs and pomegranates in a backyard greenhouse without paying for heat. The greenhouse uses the stable temperature of the earth, with underground earth tubes, to heat and cool itself.

Soren Johnson, a lead designer and AI programmer on Civilization games, discusses game AI design, including whether AI should cheat, behave like a human or be fun rather than strong. He uses the Civilization series as a case study.

Lichess founder Thibault Duplessis talks at Big Techday 10 in Munich about how Lichess works and how he built it. He covers the project's origins and technical challenges including cheating detection.

A two-minute Rouxbe cooking-school demo of how to heat a pan properly before cooking. It uses the Leidenfrost effect, where water beads and skates across a hot pan, to show when a stainless steel pan is ready.

An RSA Animate adaptation of a Dan Ariely lecture on dishonesty. It explores when ordinary people lie or cheat and how they rationalize small acts of dishonesty.

A UK tradesman's rant on the disadvantages of air source heat pumps, covering grants, heat pump types and whether they are worth it. He argues they are impractical for many British homes.

A short 2001 Tom's Hardware clip that runs Quake 3 on several popular CPU and motherboard combinations of the era, then removes the CPU cooler to see which chips survive. It shows how different processors handle losing their heatsink or fan.

A three-minute clip from Dr. Strangelove in which Mandrake and Ripper (Peter Sellers and Sterling Hayden) discuss fluoridation and 'precious bodily fluids'. It is a famous Cold War satire scene.
