Technology Connections explains how analog television produced moving images without computers, covering scanning, CRTs and standards like NTSC and PAL. It is part of a series on analog TV.

A Technology Connections video on JVC's LCCS, a display hybrid that cycles a color LCD shutter over a monochrome CRT to produce field-sequential color without dots or stripes. It builds on his earlier videos about analog TV and compatible color.

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.

Tom Scott explains why a vivid pink pigment by artist Stuart Semple cannot be fully shown on a screen, and touches on the dispute over exclusive rights to the blackest black pigment. It is a short explainer on color gamuts and pigment politics.

Jellyvision hosts Basecamp founders Jason Fried and David Heinemeier Hansson for a Q&A about open source, productivity, feature requests and taking care of customers.

The first lecture of Stanford's CS231n course on convolutional neural networks for visual recognition. It surveys the history and key challenges of computer vision, from the Cambrian explosion and Hubel and Wiesel to ImageNet.

Mark Handley of UCL looks at how SpaceX's November 2018 revisions to the Starlink constellation affect network behavior. The video visualizes the orbits and routing and estimates latencies, building on his earlier video and research paper.

Zig creator Andrew Kelley's RedisConf 2020 talk on modeling data flow with asynchronous I/O in Zig. It explains how Zig's async/await avoids function coloring, and Loris Cro demonstrates OkRedis, a zero-allocation Redis client.

A BSidesLV 2013 talk from the Sixteen Colors project on archiving the ANSI and ASCII art scene. It traces the scene's evolution from BBSs to the NFO and IRC era.

Bisqwit writes a raytracer from scratch in C++ for DOS, rendering in the 16-color VGA palette at 640x480. The video also covers color quantization and ordered dithering.

Neural-network upscaled, 60 fps, stabilized and colorized version of 1902 footage of the Wuppertal Schwebebahn suspended railway in Germany. The source film comes from MoMA. It gives a vivid view of an early-1900s city and a train system that still runs.

A hands-on comparison of how jet fuel, diesel, heating oil, kerosene, avgas and gasoline burn and what color they are. It shows that gasoline ignites more easily than jet fuel.

Megan McArdle's AEI Vision Talk 'Capital and Poverty' argues that social and financial capital work differently in low-income communities, and that this explains barriers to reaching the middle class.
