repl

LabCoatz uses mass spectrometry, with help from other science YouTubers, to reverse engineer the Coca-Cola flavor and builds a chemically-identical replica. The video walks through a year of work on the formula.

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 Computer History Museum demonstration with Dan Ingalls of Smalltalk-76 running on a Xerox Alto, recorded in 2017. He shows the live environment and discusses the system.

A short Ericsson film demoing Erlang, showing concurrent processes, debugging tools, and hot code reloading, including crashing parts of a running system while calls continue.

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 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.

Juan Benet gives an overview and demo of the go-ipfs alpha. It shows the peer-to-peer content-addressed protocol in action, including streaming video from a home computer.

Ruby developer Avdi Grimm gives a seven-minute tour of Pharo Smalltalk's development environment, focusing on tools like search-by-example and the integrated, live coding experience.

Symbolics developer Kalman Reti gives a short introductory demo of a Symbolics Lisp Machine running Genera in an emulator. It shows the context-aware command line, typed on-screen objects, and the live-editable system, including swapping in a C-compiled JPEG decoder.

Stargate Studios' 2009 virtual backlot reel shows before-and-after shots in which green screen and compositing replace locations in ordinary TV dramas and comedies. It shows how much of a seemingly real show is computer generated.

Stuart Halloway introduces REBL, a graphical, interactive tool for browsing Clojure data, extracted from Datomic tools. The talk is from Clojure/conj 2018.

Researchers from the Artificial Life Lab Graz introduce the Primordial Particle System, where a simple motion law for self-propelled particles produces cell-like structures that self-reproduce and show life cycles.

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 demo of the Symbolics Graphics Division's S-Packages, a Lisp-based 3D color graphics and animation system from the 1980s. It was later used in developing for the Nintendo 64.

Stuff Made Here builds a handwriting robot and sends its output to a handwriting expert to see whether it can pass as forgery. It walks through the engineering trials and errors along the way.

A demo of the 8pen, a gesture-based keyboard replacement for touchscreens that lets users enter text by moving around a circle. It is meant for phones, remotes and game controllers and mimics handwriting.

Adam Savage shows off his collection of analog calculators, ending with a 3D-printed, scaled reproduction of the Curta mechanical calculator built by Marcus Wu. The video examines the replica and the engineering behind it.

Valve opens up a Steam Deck to show its internal components and explain which are replaceable or upgradable. It advises against self-repair but shares the details openly.

Google ATAP's 2015 introduction to Project Soli, a radar-based sensor on a chip that tracks sub-millimeter hand motions for gesture interaction in small devices.

Fully Charged episode where Elliot drives the NIO ES8 SUV and visits a battery swap station that replaces the pack in about three minutes. It covers the ownership model of swapping and what it could mean for EV charging.

A four-minute Emacs Rocks screencast demonstrating the multiple-cursors package for Emacs. It shows how editing at many places at once can replace repetitive manual edits.

Deepfake artist Shamook's improved version of the Luke Skywalker scene from The Mandalorian season 2 finale, replacing the official CGI face with a deepfake.

Linus Tech Tips replicates the Threadripper workstation Linus Torvalds built for himself, discussing the parts such as the CPU and cooler.

Tom Scott borrows a Nio electric car in China and shows its automated battery swap station replacing the whole battery in minutes. He explains how swapping serves as an alternative to charging.

A four-minute demo of the greenhouse effect showing how increased carbon dioxide raises temperature. It uses a simple setup that is dramatic and easy to understand.
