Tom Murphy (suckerpinch) presents a deliberately trollish computer architecture built on IEEE-754 floating point, using NaN and infinity to define logic gates. He builds working hardware around the idea.

Technology Connections explains how old-fashioned non-electronic rice cookers work, using a magnet and spring switch tripped by the Curie point. It shows the thermodynamics and magnetism behind a simple appliance.

Adam Ragusea examines whether olive oil is unsafe for high-heat cooking and whether it tastes bad when heated. He cites studies showing it is among the most stable cooking oils and that smoke-point worries are overblown.

Herb Sutter's CppCon 2016 talk on lifetime safety in C++, aiming for code free of leaks and dangling pointers by default. It covers smart pointers, ownership, reference counting pitfalls and deferred reclamation resembling garbage collection.

John Carmack's roughly three-hour QuakeCon 2013 keynote, delivered from a few bullet points. Topics include his Haskell experiments with functional programming and static typing, game state, and cloud gaming.

A Wendover Productions explainer arguing that major airlines make much of their profit from loyalty programs and co-branded credit cards rather than flying. It frames airlines as quasi-banks that sell points in bulk, using United's pandemic-era loan as a hook.

Part one of a four-part upload of a BBC Horizon documentary featuring Richard Feynman, in which he talks about physics and looking at the world from another point of view.
