Scene from episode 2 of HBO's Chernobyl in which an official who once ran a shoe factory is put in charge of a critical role. It shows how unqualified appointees end up in charge of technical matters.

Dominion is a two-hour documentary using drones and hidden cameras to expose conditions in animal agriculture, including food, clothing, entertainment and research. It questions humanity's dominion over animals.

Ian Cooper's DevTernity talk revisits Kent Beck's original TDD ideas and shows where misunderstandings crept in. It argues tests should target behaviors through public interfaces rather than implementation details, so suites support refactoring instead of resisting it.

Rafal Dittwald's Clojure/north talk shows how to move from writing Java-style code in Clojure to thinking in data-driven, functional terms. He walks through a JavaScript example, refactoring imperative code step by step into a functional core.

Raymond Hettinger's PyCon 2013 talk on transforming code into idiomatic Python through a series of before-and-after refactorings. It shows how to use iterators, dictionaries, named tuples and other language features well.

Jack Diederich's PyCon 2012 talk argues that classes are overused in Python and walks through real code, refactoring away unnecessary classes, exceptions and modules. It popularized the heuristic that a class with two methods, one being __init__, should be a function.

Sabine Hossenfelder explains how close nuclear fusion really is to break-even, and why headlines about ITER and lab milestones are misleading. She distinguishes plasma gain (Q plasma) from whole-system gain (Q total) and shows the latter is still far below one.

A DEF CON 26 talk by investigative journalists and hackers on the fake science industry, with bogus conferences and predatory journals that give studies false credibility. It draws on a large investigation into the money behind them.

Ward Cunningham explains the history and intent of the debt metaphor, which he coined while refactoring the WyCash product. He says debt means code reflecting an incomplete understanding of the problem, not sloppy programming.

A clip of psychologist Jordan Peterson lecturing on intelligence and IQ, covering how it is defined and its correlation with academic and work success.
