Dr. Russell Barkley's roughly three-hour lecture on ADHD for parents of affected children. It explains what ADHD is and how the ADHD brain differs.

Dr. Russell Barkley gives a nearly three-hour lecture of essential ideas about ADHD for parents, covering what ADHD is, its effects on executive function, motivation and emotion, and how it affects children.

Conal Elliott presents his paper on automatic differentiation, deriving a simple, generalized AD algorithm from a natural specification. Varying the representation of derivatives yields forward and reverse mode algorithms that avoid the complexity and statefulness of backpropagation.

Ben Felix argues that common beliefs about renting versus buying are wrong: homes are not great investments, mortgages are not a wealth hack, and ownership does not reliably bring happiness.

Dr. Russell Barkley explains how different ADHD medications work and how they differ from one another, in a short clip.

A guest lecture Jon Gjengset gave at Two Sigma on using Rust for large, high-performance systems. It covers why Rust suits such projects, the Noria research database, a concurrent data structure used in it, and practical experience.

A sketch from the British sitcom Yes, Prime Minister in which Jim Hacker and the chief scientific advisor discuss the logic of the nuclear deterrent.

Netflix engineer Drew Gallatin explains why the company runs FreeBSD-current on its CDN. He describes the team, how they track upstream, their contributions and performance milestones, and a bug causing a 20% performance regression.

Database pioneer Michael Stonebraker argues that 'big data' is really at least four different problems: big volumes with small analytics, big analytics, velocity, and variety. He comments on where each market is heading.

Moral philosopher James Flynn explains the Flynn effect, the steady rise of IQ scores across the 20th century. He argues the shift reflects a move toward abstract, hypothetical thinking as cognitively demanding professions grew.
