Howard Abrams demonstrates, in an EmacsConf 2015 talk, how he uses org-mode's Babel and Tramp to configure and operate remote servers from a single document. Code blocks, their results and the explanatory text all live together.

Aaron Bieber, a longtime Vim user, describes his experience trying Emacs with evil mode. He covers what he found, what he missed from Vim, and what Vim could borrow from Emacs.

Steve Yegge records himself working in Emacs and shows off about a dozen features in a roughly 45-minute screen capture. It is an informal, enthusiastic tour rather than a structured tutorial.

Science writer Jay Dixit explains how he uses Emacs as a non-programmer to write, edit and research more productively. He shows his plain-text writing workflow and what led him from tools like Scrivener to Emacs.

A demo of the Symbolics Graphics Division's S-Packages, a Lisp-based 3D color graphics and animation system from the 1980s. It was later used in developing for the Nintendo 64.

Patricia Aas's EuroBSDCon keynote is about ethics for people who build software, covering how the tech industry got to its current state and what engineers can do about it. It steps back from technical detail to the bigger picture.

The first stream in the Emacs From Scratch series, building a custom Emacs configuration from zero while teaching basics. It covers a usable baseline setup and the packages for completion, themes and productivity.

Fedor Pikus's CppCon 2017 talk on C++ atomics, looking at what they let the programmer express and what the hardware actually does. It covers memory ordering and lock-free programming from basic to advanced.

A short first episode in Zaiste's Doom Emacs series, showing how to get started with Doom, an Emacs configuration aimed at Vim users. It presents Doom as a polished, fast, batteries-included distribution.

Morten Rand-Hendriksen's WordCamp Europe 2017 talk presents CSS Grid Layout as a native two-dimensional layout system that changes how web pages are structured, including responsive layouts independent of source order. It was given as browsers began shipping support.

A 2015 talk by David Deutsch with slides and audio about constructor theory and how physics, in particular the many-worlds interpretation, can be framed without probability.

A roughly four-and-a-half-hour Lex Fridman podcast conversation with Stephen Wolfram about his Wolfram Physics Project and a fundamental theory of physics, computation, life and the universe.

A short documentary about Eric Maundu's Arduino-controlled aquaponics setup in West Oakland, where contaminated soil rules out ordinary farming. Fish and circulating water grow plants without soil.

The first episode of Mike Zamansky's Using Emacs series, covering setting up the package manager for new Emacs users as a start toward customization and efficient editing.

Dennis Gustafsson, creator of Teardown, presents how he parallelized the physics solver for an upcoming game, followed by a Q&A. The talk was given at the Better Software Conference 2025.

Real Engineering looks at why nuclear power plants are expensive and how their economics compare with fossil and renewable alternatives. It is based on a video from the Illinois Energy Professors.

Swift compiler engineers explain how Swift implements generics using dictionary-passing with reified type metadata. They compare it with Java-style uniform representation and C++ or Rust monomorphization.

Robin Deits presents the JuliaRobotics organization and shows how Julia is used to visualize, simulate and control a humanoid robot. The talk touches on real-time performance and composability across packages.

A five-minute clip of a George Carlin routine arguing that the education system is designed to produce compliant citizens rather than critical thinkers. It ties schooling to the interests of the people who own the country.

Physicist Angela Collier critiques 'vibe physics', the idea that non-experts or billionaires can make scientific discoveries by chatting with AI chatbots, drawing a parallel with vibe coding.

Steve Yegge shows Efrit, a tool that gives Claude full control of Emacs, on the Vibe Coding with Steve and Gene show. Claude opens info pages, runs shells and even draws a Mandelbrot fractal in a buffer.

An IEEE Spectrum compilation of humanoid robots falling over during the 2015 DARPA Robotics Challenge Finals.

Applied Science shows how telecentric and hypercentric optics differ from normal lenses, producing no or negative perspective. The video builds a telecentric system from a Fresnel lens and demonstrates a lens that can see around objects.

A short scene from the British sitcom Yes Prime Minister in which officials describe 'salami tactics' for invading a country slice by slice. Each small step is too minor to justify a major response.

A demo of Deldo, an Emacs package that lets Emacs hooks trigger vibration events on computer-controllable sex toys. It is an absurd teledildonics project that is half performance art.
