language complexity

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.

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.

A Polish linguist tests whether speakers of Bulgarian, Polish and Croatian can understand Interslavic, a constructed language built from Slavic languages. It shows how well they follow it without prior study.

A 1975 live demonstration of the APL language by Imperial College professor Bob Spence, showing a REPL on a modified typewriter terminal and APL's appeal to non-programmers.

A five-minute video showing how to build a counter in the Imba web programming language in under a minute, then style it.

A short Dyalog demonstration building Conway's Game of Life in a single line of APL, step by step. It shows how array operations replace loops.

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 1995 Sun Microsystems film about the Self programming language, a prototype-based Smalltalk relative, showing its live, graphical programming environment.

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.

Google's 2014 reel introducing Material Design, a visual language based on a paper-and-ink material metaphor and a system of motion. It is a short promotional video.

Eric Bier, a PARC research scientist, demonstrates the Cedar integrated programming environment and language, an evolution of Mesa from Xerox PARC. The demo shows the Tioga editor, garbage collection, and a full graphical workstation environment.

Kyle Hill of Because Science explains and demonstrates, using real cards, how Magic: The Gathering can be used to build a Turing machine, a computer inside the card game.

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.

An award-winning 3D animation by XVIVO for Harvard's BioVisions showing the molecular machinery inside a cell as a white blood cell responds to a stimulus.

A roughly two-hour demonstration by Dan Ingalls of Smalltalk running on the Computer History Museum's restored Xerox Alto. It shows the integrated environment and language designed at Xerox PARC as personal dynamic media.

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.

Dave Ackley presents robust-first computing and the ULAM programming language for the Movable Feast Machine, a cellular-automata-like architecture. It was a short video for the Future Programming Workshop 2015.

SoundHound's CEO demos Hound, a voice assistant, handling fast compound natural language queries with context and detailed criteria. The video leaked before the product's official launch.

Alan Kay demonstrates GRaIL, a graphical input language system from around 1968 in which hand-drawn strokes become boxes, connections and dataflow-style programs.

OpenAI's 2021 live demo of Codex translating natural language into code, from Hello World to building a game and a Microsoft Word plugin.

A short film about the Erlang language, showing telecom systems built from lightweight processes and demonstrating hot code swapping. It is an edited version of the original Ericsson video.

Smarter Every Day host Destin Sandlin tries to hover a helicopter and finds it very hard. The video shows how the constant coordinated corrections across several control axes feel at first and how learning makes them automatic.

A demonstration of Larynx, an offline open source neural text-to-speech system supporting nine languages. The video itself is narrated with a Larynx-generated voice.

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.

ASML's short promotional fly-through of its High NA EUV lithography platform, the TWINSCAN EXE, which supports 8-nanometer resolution. It shows the machine's internals including advanced anamorphic optics.

A short Italian-language clip about the Canon Cat, a text-oriented personal computer from Canon designed by Jef Raskin, who started the Macintosh project. It shows the machine in use.
