Adam Savage's Tested spends a week with the Magic Leap One developer kit. They dig into the hardware, display technology, user experience and launch apps.

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.

An Apple WWDC24 session introducing Embedded Swift, a subset of Swift with no runtime that targets tiny microcontrollers. It demonstrates the idea on an off-the-shelf Matter smart home device.

Daniel Stone, a longtime X and Wayland developer, explains at linux.conf.au 2013 why X11's design became untenable and what motivated Wayland. The talk walks through X's history and accumulated cruft.

X.Org developer Daniel Stone explains the history and technical limits of the X Window System and why Wayland was created, debunking myths from forum comments. He covers topics such as network transparency and blocking calls.

A linux.conf.au 2013 talk by a Wayland developer who previously worked on X, telling the history of X and why Wayland was created. It covers X's hardware abstraction and architecture and why they became problematic for modern graphics.

Michael Abrash of Valve explains what affordable VR hardware will be capable of within a couple of years, and describes a prototype showing what that level of hardware can do.

Ben Eater explains how VGA signals work and builds a breadboard circuit that produces correct sync timing so a monitor recognizes the signal. He then builds toward displaying an image from simple logic chips.

Retro Game Mechanics Explained dissects how Atari's Quadrascan vector displays and vector generator hardware drew games like Asteroids and Tempest.

A recording of the TASBot block at Awesome Games Done Quick 2017, where a robot plays games via tool-assisted speedruns, including Super Mario 64 and Portal on an SNES via arbitrary code execution, and ending with a Twitch Plays segment. It showcases console exploits and creative hardware hacking.

Lyle Bickley of the PDP-1 restoration team tours the 1959 DEC machine at the Computer History Museum and plays the original Spacewar! He covers its graphics display and the MIT student programs written for it.

Ben Eater finishes building a minimal VGA video card from logic circuits. He explains analog RGB signals, stores an image in an EEPROM and builds a simple digital-to-analog converter to display it.

A follow-up review of using e-ink devices, such as Onyx Boox tablets, for productivity and as a second monitor. It covers software tips and tweaks and long-term impressions after months of use.
