multiple dispatch

Julia co-creator Stefan Karpinski explains why multiple dispatch makes Julia code and types reusable across packages with so little friction. He covers sharing basic types and sharing generic algorithms.

A four-minute Emacs Rocks screencast demonstrating the multiple-cursors package for Emacs. It shows how editing at many places at once can replace repetitive manual edits.

Peter Seibel's 2006 Google TechTalk on Practical Common Lisp, framed by the Sapir-Whorf hypothesis and Paul Graham's Blub paradox. It shows Lisp features such as condition restarts and its generic-function object system.

Short US Missile Defense Agency footage of the December 2008 free-flight hover test of Lockheed Martin's Multiple Kill Vehicle. The test showed it hovering for 20 seconds while tracking a simulated target.

A 4K AI-upscaled, subtitled fan edit of David Lynch's 1984 Dune by Spicediver that restores deleted and lost footage to form an alternative cut.

A local news report about a woman who ordered a pizza on a 911 call to discreetly signal domestic violence and give her address to the dispatcher. The coverage includes the actual dispatcher call.

An old lab video of a decerebrate cat walking on a treadmill and shifting between gait patterns as the speed changes. It is used to illustrate that much locomotion control comes from the spinal cord and body mechanics rather than the brain.

Bisqwit writes a NES emulator in C++ in about 15 minutes of tool-assisted, sped-up coding, narrated with captions. It shows an accurate emulator built with a compile-time generated 6502 instruction table. Part 2 covers compiling and running it.

Casey Muratori's lecture, originally given at the Technical University of Madrid, arguing that Conway's Law is the only viable candidate for a true law of software architecture. He explains how software mimics the organization over time, using examples like Windows' multiple volume controls.

3Blue1Brown's visual walkthrough of the attention mechanism inside transformers, covering self-attention, multiple heads and cross-attention. It is chapter 6 of his deep learning series.

Neil Fraser of Google presents Differential Synchronization, the algorithm behind MobWrite, for keeping multiple copies of a document in sync in real time. The talk argues the approach is robust, convergent and efficient.

In this first Crust of Rust episode, Jon Gjengset live-codes an example that needs multiple explicit lifetime annotations. Along the way he covers string types and generics over a custom trait.

A 1990 Lotus sales demo of Improv, a spreadsheet built for the NeXT computer that rethought the grid with named categories and multiple views. The uploader, who tested it at Price Waterhouse, presents it as an early, innovative vision of the spreadsheet.

The official demo video from Be, Inc. showing BeOS running multiple videos, media applications and a responsive desktop on 1990s hardware.

IBM's Dr. Talia Gershon explains quantum computing to five people of increasing expertise: a child, teen, college student, grad student and professional. The WIRED series format moves from simple analogies to technical detail.

Jon Gjengset's long live-coding Crust of Rust episode on async/await, focused on the mental model for using it rather than on Futures, Pin and Wakers internals. Topics include awaiting multiple futures, cancellation, executors and select.

This Old House's Ross Trethewey explains MERV filter ratings and how air filtration works, then shows how to build a localized DIY air filter, including a box fan with multiple filters.

A short clip of Richard Feynman on the difference between merely knowing how to reason mathematically and understanding why physical theories work. He discusses holding multiple equivalent ideas and guessing new laws.

Footage of a crash test of a Boeing 727 deliberately crashed in the Mexican desert, shown from multiple angles inside and outside. It is taken from a Channel 4 documentary.

The restored 4k official music video for Fatboy Slim's Weapon of Choice featuring Bootsy Collins, directed by Spike Jonze, with Christopher Walken dancing around a hotel lobby. It won multiple MTV awards and a Grammy.
