Stephen Wolfram gives a 13-minute tour of the Wolfram Language, a symbolic, functional programming language with a built-in knowledgebase. He demos querying large datasets, interactivity and deployment.

A playful music video promoting the book Land of Lisp, with a song about Lisp programming.

An eight-minute excerpt of a 1983 video featuring Seymour Papert, creator of Logo, on children learning programming and abstract ideas through embodied play. It shows kids acting out the Logo turtle.

A 1991 NeXT promotional video that stages a head-to-head programming contest between a NeXT computer and a Sun workstation. It shows NeXT's interface builder and object-oriented tooling producing an application far faster than traditional UNIX development.

Modern Vintage Gamer explains how Eric Chahi built Another World on the Amiga 500, using 2D polygons, rotoscoping and clever techniques to run well on a stock 7MHz machine.

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.

A short clip of Simon Peyton Jones talking about the future of programming languages, saying Haskell is useless in the sense that pure programs cannot have effects, while mainstream languages are useful but unsafe. He describes languages converging, with ideas such as STM and LINQ moving between them.

A 2014 talk by Geo Carncross (geocar) demonstrating kOS, a minimalist operating system and programming environment built around the k language, with early screenshots.

A 12-minute demo of the Alternate Reality Kit, built by Randall Smith at Xerox PARC in 1986. It is a simulated physical world in which users manipulate objects and program by direct interaction.

Dylan Beattie's parody of 'We Didn't Start the Fire' with lyrics made entirely of real software framework names, ending in the chorus about building yet another framework.

A family comedy video in which kids write instructions for making a peanut butter and jelly sandwich, and a parent follows them with exact literalness, producing chaos. This is the classroom-friendly version.

Ashley Feniello demonstrates VimSpeak, a voice-controlled interface for Vim inspired by Tavis Rudd's voice programming talk. The demo includes working through a VimGolf challenge by speech.

aGameScout explains rolling, the third major NES Tetris playstyle, in which players tap the back of the controller to move pieces faster than hypertapping. It covers how the technique works and where it comes from.

TechAltar's eight-minute video arguing that Chrome is becoming the new Internet Explorer as Google leverages its browser position. It covers anti-competitive behavior toward other browsers like Firefox and Edge and the role of Chromium.

A 2007 video of someone trying to write Perl code using Windows Vista's speech recognition, with hilariously bad results.

CGP Grey compares airplane boarding methods, based on an arXiv paper, and shows why the intuitive back-to-front approach is slow while random or outside-in boarding does better.

A visualization and sonification of 15 sorting algorithms, from selection sort to bogo sort, run on shuffled integers in six minutes. Each algorithm gets a size and speed scaled to its complexity.

Anders Brownworth gives a basic visual introduction to blockchain using an interactive web demo, covering SHA256 hashes, blocks, chains, distribution, tokens and coinbase transactions.

Martin Donald explains the Wave Function Collapse algorithm using Sudoku-like constraint solving and shows how he implemented it with Blender and Godot. It links demos and reference articles.

Polylog explains how algorithms can be turned into circuits and encoded as satisfiability problems, which lets you effectively run them backwards. It uses this to motivate breaking RSA, general reductions to SAT, and what P vs NP is really asking.

2swap explains how he solved the Klotski sliding-block puzzle by mapping its full state space as a graph and visualizing it. The video includes footage of the Guinness world-record solve and links to an interactive graph.

Hungarian folk dancers from Sapientia University act out the quicksort algorithm step by step, with music. It is part of the AlgoRythmics series of sorting algorithms performed as dance.

Numberphile with Daniel Erman on the Josephus problem, where people in a circle are eliminated in turn. It shows how the survivor's position follows a neat pattern tied to powers of two and binary.

A short demo of real-time sparse voxel octree rendering, shown by Jon Olick at Siggraph 2008. It shows a detailed model rendered by ray casting through the octree.
