Scott Manley explains the nuclear salt water rocket, Robert Zubrin's concept of a rocket fueled by a rapid nuclear reaction in uranium salt dissolved in water. He covers its extraordinary performance and the dangers of managing it.

A 47-minute documentary on Allan Savory and how he used Holistic Management to restore degraded land in Zimbabwe. It covers rotational grazing, soil health and regenerative agriculture.

A short video explaining the Intel Management Engine, a hidden embedded computer inside Intel machines with deep access to hardware. It is presented from an insider's perspective and raises backdoor and NSA concerns.

A short research demo of Autonomous Intersection Management, a protocol in which self-driving cars reserve slots through an intersection instead of obeying signals or stop signs. It uses UT Austin's autonomous vehicle Marvin and a simulation to show cars crossing without stopping.

Josef Holzer walks through his family's Krameterhof, one of Europe's oldest permaculture farms in the Austrian mountains, with fish ponds, terraces, fruit trees and grazing animals. It showcases water management and microclimates.

A short overview of Tabs Outliner, a Chrome extension that shows browser tabs and windows as a nestable tree. It demonstrates organizing, saving and restoring tabs.

A 1994 talk by systems thinker Russ Ackoff, who knew W. Edwards Deming, on continuous versus discontinuous improvement. It ends with an unexpected lesson.

An 8-minute National Geographic short film about David Bamberger, who bought 5,500 overgrazed acres in the Texas Hill Country and restored the land and its aquifers over about 50 years.

A short clip of Steve Jobs arguing that the best people are self-managing and that professional managers who cannot do the work add little. He says leadership is about a shared vision.

A June 1986 CNN interview with physicist Richard Feynman about the Challenger disaster and the management failures he found while serving on the investigating commission.

Excerpts from W. Edwards Deming's Red Bead Experiment, where workers draw beads from a bowl and are judged on red ones that are largely down to chance. It shows how system variation, not individual effort, drives results.

Technology Connections explains why electric kettles are uncommon in the US, centering on 120V circuits limiting power. He tests ways of boiling water on gas, electric ranges and kettles.

Glenn Vanderburg argues at Lone Star Ruby Conference 2010 that university-style software engineering does not work, and asks what real software engineering would look like. He revisits the waterfall model and what engineering means in other fields.

A short video of David Foster Wallace's 'This Is Water' commencement speech about awareness and choosing how to think. It argues that the most obvious realities are the hardest to see, using the fish-in-water parable.

A Business Insider investigation into the US boom in AI data centers, mapping where they are, who owns them, and how much power and water they consume. It looks at the costs borne by communities, with a focus on Virginia.

Fermilab's Don Lincoln explains why light travels slower in water and glass. He knocks down common wrong explanations such as absorption and re-emission, then gives the wave-mechanics reason tied to refractive index.
