Kurzgesagt's animated take on climate change argues that, despite alarming headlines, there are real reasons for hope as technology, policy and public attitudes shift. It surveys trends and solutions while acknowledging the scale of the problem.

Jon Moore's Strange Loop 2017 talk argues that rate limiting is the wrong tool for protecting services from noisy clients. He proposes concurrency-based capacity management and quotas instead.

Kurzgesagt examines who is responsible for climate change, comparing historical, current and per-capita emissions by country. It argues that individual footprints are a distraction from larger responsibility.

A three-minute excerpt of a Steve Jobs interview in which he describes how monopolies let sales and marketing people displace product people, rotting a company's product sensibility, with Xerox as the example.

The official trailer for the documentary General Magic, about the secretive Apple spinoff that tried to build a handheld communicator in 1990 and whose ideas shaped the smartphone era.

Timothy Baldridge presents Pixie, a lightweight Lisp built on RPython, at Strange Loop 2015. It covers C interop, immutable data structures, fast startup and async-by-default IO.

A one-minute rap by George Hotz (geohot) aimed at Sony, made as an entry for a contest while Sony was suing him over the PS3 jailbreak. It is a humorous diss track delivered from the middle of the lawsuit.

A short Boeing-supplied clip where the 737 MAX program's chief project engineer explains how the lengthened landing gear of the MAX 10 folds up. It shows the gear model in motion.

A Fifth Gear segment in which Tiff Needell tests autonomous emergency braking systems in the Mercedes S Class, Volvo V40 and VW up!. The cars are driven toward an inflatable dummy car to see how each system performs.

Top Gear segment in which Hammond and May try to turn a Reliant Robin into a space shuttle. Launching is easy, but landing it safely is the problem.

The first chapter of 3Blue1Brown's Essence of Linear Algebra series, introducing vectors with animated geometric visuals. It begins a series that builds intuition for linear algebra from the basics.

Guy Steele's 1998 OOPSLA keynote on designing a programming language that its users can grow. He builds the talk using only one-syllable words and terms he has defined, to demonstrate the idea.

A SIGGRAPH 2019 course on geometric algebra. Charles Gunn gives an intro, then Steven De Keninck gives a programmer-focused course with live examples in ganja.js.

Jonathan Blow's first talk on designing a new programming language for games, which became Jai. He explains the problems with C++ and why Go, Rust and D do not fit game development.

A five-minute preview of 3Blue1Brown's Essence of Linear Algebra series, which uses animation to build geometric intuition for topics from a standard linear algebra course.

An animated introduction to geometric algebra, presented as a language that can describe most of physics. It was made with manim and covers multivectors and how they generalize familiar tools like cross products and quaternions.

The Thought Emporium's host describes making and taking a DIY gene therapy to treat his own lactose intolerance. It uses an AAV virus to deliver DNA coding for the lactose-digesting enzyme, made with biohacker Gabriel Licina's help.

An episode of the Norwegian documentary series Brainwash, in which a comedian interviews academics from different sides about gender differences and gender equality. It looks at why more equal societies can still show unequal career choices.

Historian and journalist Gwynne Dyer gives a long UBC talk on how climate change will reshape international politics. He covers food, borders, refugees and the possibility of unilateral geoengineering by affected nations.

ScienceClic explains why the rubber sheet analogy for general relativity is misleading and offers a new visualization that includes the curvature of time and shows gravity as motion through curved spacetime.
