Two Google engineers perform a mock coding interview and then discuss best practices for candidates, including asking clarifying questions and communicating while solving.

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.

A live mock programmer interview in which Casey Muratori interviews game developer Shawn McGrath using a less confrontational format devised by Chris Hecker. It gets deep into technical details while showing how the candidate actually thinks and works.

A demo of writing technical documents in Emacs Org mode using org-babel, so that code blocks and generated content stay consistent when things change. The author shares the demo files and his dotfiles.

A roughly hour-long live hacking session in which Go team members Andrew Gerrand and Brad Fitzpatrick write the new version of tip.golang.org, the site serving leading-edge Go documentation. It is unedited pair programming on a real Go project.

John Carmack live-codes a simple VR application at Oculus Connect 2 using a Racket-based environment for rapid development and deployment on Gear VR.

A long George Hotz livestream in which he explores the coronavirus genome and molecular biology from scratch using a browser and Python, hacking on the science in real time.

Saqib Shaikh, a blind developer, shows how he writes and debugs code in Visual Studio 2017 using a screen reader. The short demo shows an expert doing ordinary developer tasks.

Andreas Kling ports the game Diablo to SerenityOS, his from-scratch Unix-like operating system, using the devilutionX project. The roughly 80-minute session shows what porting third-party software to the OS involves.

Jon Gjengset spends about three hours livecoding complex changes in a Rust codebase with agentic AI tools, testing his hypothesis that AI is weak at non-pattern work. He documents where Claude Code helps and where it struggles.

A timelapse of Notch (Markus Persson) making Metagun, a game built from scratch in 48 hours for Ludum Dare 18. It shows the whole coding session sped up.

Footage of Notch (Markus Persson) live-coding his Minicraft game in Java during a Ludum Dare 48-hour game jam. It shows a working game developer building a complete small game from scratch.

A short unscripted demo of writing FizzBuzz in JavaScript with a generator function on a steno keyboard, typos included. It gives a feel for what real coding in stenography looks like.

A short social experiment video in which people mimic the New York subway practice of workers pointing at signs and signals. It makes the point cheerfully.

Samuel Falvo II live-codes a text preprocessor and blog engine in Forth over about an hour. It shows Forth's dictionary being snapshotted and restored in place of mutation, and how a small Forth system gets real work done.

A DevOps YouTuber tests GitHub Copilot on a range of Leetcode problems and finds it solves most immediately, with a few needing tweaks and some far off. He concludes it would outperform him in a FAANG-style interview.

A five-minute SuperMemo demo of incremental reading: importing a Wikipedia article on nutrition, extracting passages, making cloze deletions and finishing the item. It lists the keyboard shortcuts used.

Fully Charged episode where Elliot drives the NIO ES8 SUV and visits a battery swap station that replaces the pack in about three minutes. It covers the ownership model of swapping and what it could mean for EV charging.

Footage of the US Navy's Phalanx CIWS, a radar-guided 20 mm Gatling gun, firing in live target practice. The Phalanx serves as terminal defense against anti-ship missiles.

Tom Scott borrows a Nio electric car in China and shows its automated battery swap station replacing the whole battery in minutes. He explains how swapping serves as an alternative to charging.
