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.

Casey Muratori captures CygnusEd Professional running on an Amiga 2000, showing how smoothly it scrolled text. He notes the real effect is better on a period CRT.

A short demo showing slow 2D drawing in the Windows 7 GUI compared with XP. It attributes the slowdown to the display driver model lacking hardware accelerated GDI.

A short Microsoft promo comparing classic Teams with the rewritten new Teams side by side, claiming faster startup and better performance. The new version is shown taking around nine seconds to launch.

A short side-by-side recording by Jake Archibald of the same animation demo running in Chrome, Firefox, Safari and Servo WebRender nightlies on a 60Hz display. It shows the smoothness difference of GPU-based rendering.

A one-minute clip of slime mold placed on a map with food at the cities around Tokyo, growing a network that approximates the Tokyo-area railway system.

The first of a short series by Welch Labs on building a complete neural network in Python. It introduces the data and the architecture of a simple network before later parts cover forward propagation, gradient descent, and backpropagation.

A bot built by Robin Baumgarten plays Infinite Mario using A* path-finding, shown as a red planned path that updates as new obstacles appear. It won the Mario AI competitions and uses only on-screen information.

A short demo of the Deep Visualization Toolbox, which shows the activations inside a convolutional neural network as it processes live camera input. Viewers see individual units responding to edges, faces and text.

OpenAI's short demo of agents playing hide-and-seek in a simulated environment. Through self-play, the agents develop six progressively more complex strategies and counter-strategies, including tool use.

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.

A one-minute clip from a 2016 Toronto conference in which Geoff Hinton comments on deep learning and radiology. He suggests radiologists should stop being trained because machines would soon read scans better.

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

A two-minute Insider Tech clip on DeepMind's simulated agents that learned to walk, run, jump and climb without guidance, with the goofy resulting gaits.

Toyota Research Institute presents an approach for teaching robots new dexterous behaviors from human demonstration. It explains why this capability matters and what advances made it possible.

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