An overview of the PTVS 2.0 beta feature for debugging Python and C/C++ together in one session in Visual Studio.

A short demo of Code Bubbles, an IDE interface built around editable code fragments in bubbles instead of files. It was a research prototype for Java development.

Hungarian folk dancers from Sapientia University act out the quicksort algorithm step by step, with music. It is part of the AlgoRythmics series of sorting algorithms performed as dance.

Scott Manley's short animation shows every asteroid discovery from 1970 to 2015 plotted over time in 8K. It makes visible how survey technology made discoveries accelerate and where telescopes looked.

A one-minute clip from Cambridge's Prof. Holger Babinsky that debunks the equal transit time explanation of lift. It shows how air actually flows over a wing.

A 1993 VHS demo of Lucid Energize, a database-backed, incremental C/C++ programming environment built on XEmacs. It shows features like incremental compilation, live debugging and hyperlinked output.

Henry Segerman and collaborators demonstrate virtual reality experiences in non-Euclidean spaces, including hyperbolic and mixed hyperbolic-Euclidean geometry. The browser-based demos let viewers move through these spaces and show how strange the geometry feels from inside.

Steve Yegge records himself working in Emacs and shows off about a dozen features in a roughly 45-minute screen capture. It is an informal, enthusiastic tour rather than a structured tutorial.

Casey Muratori gives a fast tour of the RemedyBG debugger for Windows, which he uses daily. He shows its speed and features, especially the watch window.

The original five-minute Dropbox demo video, which presented the product's features before a finished product existed. It was aimed at technical early adopters and became famous as a launch strategy.

The author of copyparty introduces the FOSS file server he has built over five years, demoing its features such as resumable uploads, WebDAV and deduplication. The video itself is shown running on a demo server.

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 12-minute film in which Erlang's creators demonstrate the language's fault tolerance and live-system features, including phoning each other to show it working. This version has fixed audio.

Doug DeMuro reviews the Rivian electric delivery van built for Amazon, walking through its quirks, features and design innovations. It is a long, detailed tour of the vehicle inside and out.

A short demo of an open-source Krita plugin that uses Stable Diffusion to generate and edit images in place. It adds ControlNet scribble and line-art support. You select an area, push a button, and new matching content appears.

Jeff Geerling looks at a Sharp NEC commercial display with a slot for a Raspberry Pi Compute Module. It is a large screen without built-in smart TV features or tracking.

The Quantified Scientist, a sleep researcher, tests Apple Watch sleep tracking against a research-grade Dreem 2 headband, comparing accuracy for sleep stages, deep and REM sleep. The review is data-focused rather than feature-focused.

Robert Llewellyn of Fully Charged takes an early, 19-minute test drive of the Honda e electric car in Frankfurt. He looks at its acceleration, camera wing mirrors and tight turning circle.

A live-coded demo by Jonathan Blow showing how to get object-system-style expressiveness in a data-oriented way, covering structure-of-arrays layouts and composition. It shows features of his Jai language that make programs fast.

Hugh Jeffreys tears down the iPhone 13 and assesses its repairability, showing how Apple ties parts like the display and Face ID hardware to specific devices. He demonstrates that swapping parts, even genuine ones, can disable features.

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.

A one-minute visualization of a simulated ant colony in which ants follow pheromone trails, with the source code on GitHub. It shows emergent behavior arising from simple rules.

CNLohr maps Wi-Fi signal strength at high resolution by moving an ESP8266 on a CNC mill, then visualizes the 3D data in WebGL. The result shows interference patterns in space.

Jonathan Blow gives a formal, hour-long demo of his Jai compiler focused on the implicit context feature. The context carries things like allocators through a program without explicit parameter passing, and the talk walks through the code.

Kefrens' Desert Dream, an Amiga demoscene production released at The Gathering in 1993, recaptured in HD at 50fps. It features code, music and graphics by a team of scene members.
