The first episode of a screencast series building djb's redo build system from scratch in Haskell. It explains the purpose of redo, writes initial code and sets up a GitHub repository.

A 2018 vlog showing how to use the windshield wipers on a Tesla Model 3, including auto mode, manual settings and voice commands. It is labeled outdated.

David Beazley's workshop screencast builds asynchronous programming in Python from scratch, starting from callbacks and continuations and replacing threads to show how concurrency works underneath.

A three-minute Emacs Rocks screencast by Magnar Sveen demonstrating paredit, which edits Lisp code structurally as a tree of s-expressions rather than characters.

Allieway Audio gives an informal introduction and live-coding demo of ORCA, a free esoteric programming environment for building procedural sequencers from Hundred Rabbits. It walks through the interface and how to make music with it.

Kristy Viers demonstrates the iPhone Magnifier combined with VoiceOver to describe the user's surroundings. She shows how the built-in feature reports scenes, faces and lighting.

Mitchell Hashimoto walks through his setup for running a NixOS virtual machine on a Mac as his development environment, with a config repo on GitHub.

David Beazley's PyCon 2019 tutorial derives the lambda calculus from the ground up in Python, using only single-argument functions. He builds booleans, numerals and more with no other language features.

John Scholes builds a depth-first tree-search operator step by step in a Dyalog APL session. It covers higher-order functions and runs the search on the N-Queens problem.

A walkthrough of installing Synapse, Riot and Jitsi from scratch on Debian to run your own Matrix communication service. The description warns it is now quite outdated and links to updated material.

Day 21 of Casey Muratori's Handmade Hero, which covers loading game code dynamically from a DLL on Windows. He builds hot reloading of C game code from scratch in about an hour and a half.

The first part of a ShaderToy live-coding series that lays the groundwork for The Drive Home, a rainy night-traffic shader. It covers basic setup and builds toward rain and bokeh effects.
