A short video accompanying the CVPR 2018 paper Learning to See in the Dark. It shows a neural network producing sharp images from very low-light raw sensor data, compared against denoising approaches.

Tech Tangents sets up original Doom's three-screen multi-monitor mode, which required a separate networked computer for each monitor. The video covers the hardware and setup work and the result.

A short visualization from HotNets researchers of routing and latency over SpaceX's proposed Starlink constellation, based on its FCC filings. It shows orbital shells, link topology and how inter-satellite routes could beat terrestrial fiber on long distances.

A video presenting an Intel research paper on enhancing the photorealism of synthetic images. A convolutional network uses rendering intermediates, shown on GTA V footage that comes out looking like real street scenes.

A brief demo of the Smalltalk debugger, including defining a method that doesn't exist yet while the program is stopped mid-crash.

Tested explains how Apple's Touch ID recognizes fingerprints, then tries to defeat it using fake fingers and prints, retracing methods claimed by a German computer club.

AlphaPhoenix shows off a new camera that films at two billion frames per second and uses it to film a laser pointer pulse. He investigates a strange quirk in how the speed of light appears on camera.

A five-minute lightning demo of VisiData, a terminal tool for exploring and manipulating data. It uses two months of NYC 311 complaint data to drill down, plot points on a virtual map and save selected rows.

A two-minute video of Conway's Game of Life running inside Conway's Game of Life, built from OTCA metapixels and Golly. It zooms smoothly between scales.

A two-minute time-lapse from the Kishony Lab showing bacteria spreading across a giant petri dish with increasing antibiotic doses, evolving resistance as they go.

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 DIY demonstration of a fan-and-screen mosquito trap that uses carbonated water as a CO2 attractant. The creator reports catching about 8,000 mosquitoes in two nights.

A two-minute 2008 clip from Sun's Fishworks team in which Brendan Gregg uses DTrace to show disk latency spiking while he shouts at a rack of drives. Bryan Cantrill narrates the demonstration.

The Google I/O 2009 keynote introducing Google Wave, a real-time collaborative communication and document platform. It includes a long live demo and the developer preview announcement.

Two Google engineers perform a mock coding interview and then discuss best practices for candidates, including asking clarifying questions and communicating while solving.

A ShortCircuit (Linus Tech Tips) review of Nvidia's RTX Voice, which uses GPU-based neural networks to remove background noise from microphone audio. It demonstrates how well the filtering works.

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.
