Jon Gjengset spends about three hours livecoding complex changes in a Rust codebase with agentic AI tools, testing his hypothesis that AI is weak at non-pattern work. He documents where Claude Code helps and where it struggles.

Steve Mould messes with an automated phone bot by telling it to forget its previous prompts and give him a bolognese recipe. It is a short demo of prompt injection against an AI voice agent.

A short NASA Goddard visualization from the GEOS-5 model showing a year of atmospheric carbon dioxide moving around the globe. It shows plumes from sources, hemispheric differences and seasonal swings as plants grow and die back.

A Microsoft Flight Simulator Feature Discovery episode in which CEO Sebastian Wloch explains the new aerodynamics simulation for the 2020 release.

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 keynote launch video for the Rabbit r1 handheld AI device, presenting its assistant and a teachable mode for agents. It is a product announcement with live-style demos.

A short Unitree promo for its G1 humanoid robot, priced from $16K, showing agile motion, dexterous hands and imitation and reinforcement learning.

A short demo of a 3D Wayland compositor built with Qt 5 and QtWayland, mapping input to and compositing the output of Wayland applications in a 3D scene, also running on a Raspberry Pi.

Boston Dynamics shows its Atlas humanoid robot performing a gymnastics and parkour routine, using optimization-generated motions and a model predictive controller.

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.

CuriousMarc connects a restored 1930 Model 15 Teletype to a Linux machine and uses it as a terminal, after commenters requested it. The video shows the challenges of linking a 5-bit mechanical device to a modern OS.

John Carmack live-codes a simple VR application at Oculus Connect 2 using a Racket-based environment for rapid development and deployment on Gear VR.

A SIGGRAPH Asia 2013 research demo of 3-Sweep, a tool for extracting editable 3D objects from a single photo using a few user strokes. It predates modern AI image tools.

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

Clickspring makes the pin-and-slot epicyclic gearing of the Antikythera Mechanism, the module modelling the Moon's variable motion in the Greek theory, by hand.

Short Airbus footage of its ATTOL project, in which a test aircraft performed a fully automatic, vision-based take-off at Toulouse-Blagnac. The crew ran eight take-offs over several hours.

Raw 1991 home footage of a working Etak Navigator, the 1985 in-car navigation system that predated consumer GPS. It shows the system's cassette-based map display and explains its augmented dead reckoning using wheel sensors.

A hands-on comparison of self-parking systems on a Tesla Model S and 3 (including AP1 vs AP2), an Audi e-tron GT, a Ford Mustang Mach-E and a BMW i4 M50. It tests both parallel and perpendicular parking and finds Tesla's newer vision-based parking noticeably weaker than the others.
