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 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.

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.

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

Tom Scott explains for Computerphile why handling time and timezones in code is so hard, walking through a simple web app that computes how long ago something happened. It covers the quirks of timezones and calendars and ends in an exasperated rant.

A humorous 10-minute parody sequel to Erlang: The Movie, in which Erlang's creators discuss the aging language and meet a surprise helper. It plays on the Outlaw Techno Psychobitch joke for OTP.

Viznut demonstrates bytebeat, experimental music generated by extremely short C programs. It is the first of a series of videos on the technique.

An episode of FunFunFunction explaining monads in JavaScript as functors that also implement flatMap. It builds on the preceding functor episode and works through code examples.

Matthias Wandel tests old and new code on a range of PCs, including a new mini PC, to measure how much faster modern hardware really is. He also shows optimization techniques such as branchless code, with benchmark programs on GitHub.

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 12-minute film in which Erlang's creators demonstrate the language's fault tolerance and live-system features, including phoning each other to show it working. This version has fixed audio.

A short demo of Code Bubbles, an IDE interface built around editable code fragments in bubbles instead of files. It was a research prototype for Java development.

Gary Bernhardt argues that software history moves in reactions to earlier tools, and that new tools are not simply better in every way. He distinguishes capability (what a tool allows) from suitability (what it fits), and warns against repeating past mistaken reactions.

Tom Scott recounts the worst typo he ever made, a subtle mistake in code with destructive consequences at a previous job. It is a cautionary tale about irreversible operations.

A comedy sketch by Kai Lentit in which a senior JavaScript developer is interviewed, parodying the chaos of the JavaScript ecosystem.

The Michigan TypeScript group shows the Doom engine running entirely inside the TypeScript type system. It is open source, and two follow-up videos cover why and how they did it.
