stack machines

A five-minute demo of the Common Lisp debugger fixing a bug, recompiling a single function, and resuming execution from the failed stack frame. It shows how to avoid re-running long computations.

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.

A short animation illustrating the proposed nanofactory concept, where nanomachines assemble atomically precise parts into larger products. It depicts how such a system might build macroscopic goods from raw materials and energy.

A short video of a man moving a 20 ton stone block by himself using wood and levers. It is part of a pyramid-mysteries channel.

8088 MPH is a demoscene production for the original 1981 IBM PC with CGA graphics and a 4.77MHz 8088, shown with real composite output. It competed at Revision 2015 and pushes the hardware well past what it was thought capable of, breaking emulators.

A very short animation of a kinesin motor protein walking along a microtubule inside a cell, carrying cargo.

A demonstration of SymbOS, a multitasking operating system for 8-bit Z80 machines, running on a real MSX turboR with an MP3MSX card and a CF IDE interface. It shows the OS playing audio and running a graphical desktop on very old hardware, captured from the real machine and not an emulator.

A short demo of SEdit, the structure editor for Interlisp-D on Xerox Lisp machines in the 1980s, which edits code as trees rather than text.

A Tiny Desk concert in which pianist Dan Tepfer plays with a Disklavier player piano driven by a program he wrote that responds to his playing. He performs four pieces from his Natural Machines project.

A short clip of a Renault F1 engine playing God Save the Queen by precisely controlling its RPM, recorded at Goodwood. It demonstrates how finely the drivetrain can be controlled.

Mark Rober builds a machine that plays the Cyclone arcade game with perfect timing and discovers the game is rigged so that perfect play still loses. The video explains the physics and electronics tricks behind carnival-style skill games.

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 one-minute clip of Rochus Keller performing as a one-man band: slap bass with the left hand, Rhodes and lead guitar with the right, and drums with the feet.

A showcase of the author's fifth-generation quad-core computer built entirely from Minecraft redstone, after two years of development. It features cache, a hardware stack, a GPU driving a 15x15 display, and serial I/O ports.

LGR reviews the weeCee, a tiny mini PC that boots MS-DOS and Windows from a microSD card. It offers Sound Blaster Pro and General MIDI compatibility with VGA output, and the video tries it with DOS and Windows 98 games.

Terry Davis, author of TempleOS, demonstrates his SimStructure physics simulator and builds a PID controller using math from Numerical Recipes in C. The description notes PID controllers are used in everything from rockets to espresso machines.

A University of Tokyo demo of a rock-paper-scissors robot that always wins, using high-speed vision to read the human hand and respond faster than people can perceive.

Stuntman Gary Connery jumps from a helicopter at 2,400 feet in a wingsuit and lands without a parachute on a runway of stacked cardboard boxes, the first such landing.

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

Short footage of the General Electric Cybernetic Anthropomorphous Machine, or Walking Truck, a 1960s quadruped vehicle operated by a human driver using hydraulic limbs. The uploader notes it predates Big Dog by decades.

A promotional video from Oxbo showing its blueberry and raspberry harvesting machines in operation. It demonstrates mechanical berry harvesting at commercial scale.

Ben Katz's custom robot solves a Rubik's Cube in 0.38 seconds. The description links to the hardware and software write-ups.
