A tool-assisted speedrun of Ocarina of Time at Summer Games Done Quick 2022, using TASBot and arbitrary code execution to reach an alternate ending in about 53 minutes. The run is introduced by its creators and followed by an interview.

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.

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 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.

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.

A long live-coded DJ set in which Sam Aaron creates all the music in real time by writing code in his Sonic Pi system. It demonstrates algorithmic electronic music performance.

A live-coded demo by Jonathan Blow showing how to get object-system-style expressiveness in a data-oriented way, covering structure-of-arrays layouts and composition. It shows features of his Jai language that make programs fast.

Jonathan Blow demos his prototype programming language, covering the base language and compile-time execution, including running a game while compiling. The video is about 70 minutes of demo followed by Q&A.

Jonathan Blow gives a formal, hour-long demo of his Jai compiler focused on the implicit context feature. The context carries things like allocators through a program without explicit parameter passing, and the talk walks through the code.

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.
