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.

A seven-minute demo from the author of Notcurses, a C library for text user interfaces. It shows the 2.3.0 release, which adds Sixel and Kitty bitmap graphics integrated into its multiplane character-graphics model.

Andreas Kling ports the game Diablo to SerenityOS, his from-scratch Unix-like operating system, using the devilutionX project. The roughly 80-minute session shows what porting third-party software to the OS involves.

An episode of C++ Weekly in which Jason Turner shows modern C++14 compiling to the Commodore 64's 6502. It demonstrates writing efficient high-level code for 8-bit hardware.

A compilation of hover tests of exoatmospheric kill vehicles, the small rocket-propelled interceptors used in missile defense, including early prototypes from the late 1980s. It shows the vehicles maneuvering with thrusters in test facilities.

A 1993 VHS demo of Lucid Energize, a database-backed, incremental C/C++ programming environment built on XEmacs. It shows features like incremental compilation, live debugging and hyperlinked output.

Project Farm tests six penetrating oils, including WD-40, PB Blaster, Liquid Wrench and an ATF and acetone mix, on rusted bolts. Liquid Wrench placed first and the homemade mix second.

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.

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.

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 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 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.

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.

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

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

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.

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.

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.

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.

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.

Samuel Falvo II live-codes a text preprocessor and blog engine in Forth over about an hour. It shows Forth's dictionary being snapshotted and restored in place of mutation, and how a small Forth system gets real work done.

A roughly ten-minute demo of Microsoft's Intentional Programming research system, showing its editor and an unusual way of working with code. It is the first of two clips cut from a longer video.

Part 2 of an old Microsoft Research demo of Intentional Programming, showing the compiler side of a system that stores programs as abstract structure rather than text. The uploader says the companion editor clip is clearer.

Joe Barnard of BPS.space shows his model rocket Scout F landing vertically like a SpaceX booster after seven years of attempts. The video documents the successful landing and the build-up to it.

The Quantified Scientist, a sleep researcher, tests Apple Watch sleep tracking against a research-grade Dreem 2 headband, comparing accuracy for sleep stages, deep and REM sleep. The review is data-focused rather than feature-focused.

Footage of an Airbus A380 engine blade-off test, in which a fan blade is deliberately released at full thrust to show the engine contains the failure.

A short SpaceX video of the Dragon 2 pad abort test, in which the capsule's thrusters fire to carry it away from the launch pad. It also shows the pad deluge system.

LockPickingLawyer cuts through a LiteLok flexible bike lock with cable cutters in about 16 seconds, one of several videos defeating the product.

A short test firing of the XRS-2200 linear aerospike engine at NASA Stennis Space Center, which was designed for the cancelled X-33 VentureStar. The engine is shown at roughly 80 percent of max thrust.

A short demo of a GPT-powered Linux shell that guesses the bash command you meant and sometimes hallucinates absurd results. The creator stresses that it is real and should not be trusted.

A short clip of a jet-powered flying lawnmower, the Sky Cutter, and related RC flying lawnmowers.
