Thai farmer Jon Jandai talks about leaving Bangkok to farm and build his own house, arguing that food, shelter, clothing and medicine are easy to provide and that modern life is made needlessly complicated. He founded the Pun Pun Center for Self-reliance.

Bill Gates's 2015 TED talk, given after the 2014 Ebola outbreak, argues the world is unprepared for the next fast-spreading epidemic. He calls for scenario planning, vaccine research, and trained health workers, in the way countries prepare for war.

A surreal multimedia TEDxSarasota performance by Magic Leap founder Rony Abovitz, held on 12/12/12, mixing performance art with talk about imagination and creativity.

Mike Acton of Insomniac Games argues that a program's purpose is transforming data, and shows how common C++ approaches work against that in performance-critical game development. He covers cache behavior, data layout and the limits of compilers.

A short excerpt from Werner Herzog's film Lo and Behold in which Ted Nelson lays out his ideas about hypertext and interconnection. Herzog concludes that Nelson is the only sane person in computing.

Will Wilson of FoundationDB explains how the team tested their distributed database using deterministic simulation. By running the whole system in a simulator with injected faults and reproducible seeds, they could find rare concurrency and network bugs.

Paul Chiusano's Strange Loop 2019 talk introduces Unison, an open-source functional language for distributed, elastic systems. It covers content-addressed code identified by hashes of the syntax tree, a codebase manager, and algebraic effects called abilities.

Martin Kleppmann's QCon London 2018 talk on keeping data consistent in distributed systems without a central leader. It surveys CRDT algorithms for syncing devices and collaborative editing over peer-to-peer networks.

A short clip from an ACM and Computer History Museum interview in which Leslie Lamport discusses writing his paper on time, clocks and the ordering of events. He explains its link to special relativity.

Chris Lonsdale presents a TEDx talk on how adults can learn a language in about six months, centering on immersion, comprehensible input and a practical learning methodology.

Psychologist Barry Schwartz argues in this TED talk that abundant choice makes people more paralyzed and dissatisfied rather than freer and happier.

Sir Ken Robinson argues, with humor and stories such as that of choreographer Gillian Lynne, that education systems undermine creativity and should be changed. It is one of the most viewed TED talks.

Scott Galloway's TED talk uses data to argue that young Americans are financially worse off than earlier generations, calling it a great intergenerational theft. He covers root causes and what could change it.

Adam Savage's Tested spends a week with the Magic Leap One developer kit. They dig into the hardware, display technology, user experience and launch apps.

Andrew Kelley, creator of Zig, presents practical data-oriented design techniques for shrinking memory footprint and making programs cache friendly. He ends with a case study of how these ideas sped up the Zig compiler.

A CppCon 2018 talk arguing that OOP has failed to deliver on reuse and performance, and presenting data-oriented design for C++ with practical worked examples from real systems.

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.

Robert C. Martin (Uncle Bob) gives a talk on the SOLID principles of object-oriented and agile design, in the context of encapsulation and clean code.

A standing whiteboard conversation at Lang.NEXT 2012 among Carl Hewitt, Erik Meijer and Clemens Szyperski about the actor model. Hewitt, who originated the model, explains its foundations.

Dr. K of HealthyGamerGG argues that gifted kids can be seen as special needs, tracing a path from the gifted label to burnout and perfectionism.

A four-minute 2006 explainer on trusted computing, describing what it is and whether users should support it, with a skeptical DRM angle.

Skateboarding pioneer Rodney Mullen talks about how the open skate community and its environments drive the invention of new tricks out of pure passion. He draws parallels to collaboration and open source.

Bassist Victor Wooten argues that music should be learned the way children learn their first language: by immersion and play, without early correction or rigid academic instruction. He draws on how babies pick up speech from the people around them.

Brian Will makes the case for procedural programming over object-oriented programming, arguing that OOP's promised encapsulation and decoupling are largely illusory. He analyzes real code examples and the problems of tying data to behavior in classes.

Brian Will follows up his earlier anti-OOP video by walking through four short code examples, including Java code in the style of Uncle Bob, to show how object-oriented design complicates simple programs. It argues that OOP hides and scatters state and adds needless indirection.

Raph Levien presents his new Rust GUI framework, built on data-oriented design and ideas from entity component systems, for the Xi editor. He weighs the approach against alternatives and discusses pros and cons.

Brian Will critiques object-oriented programming and rewrites a roughly 3800-line OO program in a procedural style, cutting code and complexity. It is part of a series of OOP critiques.

A long recorded seminar in which Alan Kay discusses object-oriented programming, probably from the mid-1980s. He covers the original idea of objects, messaging and the work done at Xerox.

A tool-assisted speedrun of Pokemon Yellow on Game Boy Color that uses glitches and frame-precise inputs to make the game execute an arbitrary program. It was later obsoleted by an improved run.

A Polish linguist tests whether speakers of Bulgarian, Polish and Croatian can understand Interslavic, a constructed language built from Slavic languages. It shows how well they follow it without prior study.

Gary Wilson's TEDxGlasgow talk argues that internet pornography hyperstimulates the brain's reward system and can cause symptoms that reverse when people stop. TED notes that several claims are not supported by respected academic studies.

Will Stephen's humorous six-minute TEDx talk shows presentation techniques that make you sound brilliant while saying essentially nothing.

A short TEDx talk by Joe Smith teaching how to dry your hands with a single paper towel. It shows a simple technique for cutting waste.

Cognitive scientist Donald Hoffman argues in this TED talk that evolution shaped perception to track fitness rather than truth. He uses evolutionary simulations and the Australian jewel beetle as examples.

Reggie Watts performs at TED 2012, blending vocal looping, beatboxing, poetry and comedy across musical genres in a larger-than-life improvised set.

Dr. John McDougall argues at TEDxFremont that starch-based diets are what humans were born to eat, drawing on 40 years of nutrition and disease work.
