A short clip of Lucille Bluth from Arrested Development asking how much a banana could cost.

Rich Hickey's philosophical talk from the first Clojure Conj in 2010. He argues that good design comes from deliberate, away-from-keyboard thinking, and describes how to feed the background mind so it solves problems.

The first clip from Russell Barkley's 30 Essential Ideas about ADHD series, introducing ADHD as a chronic developmental disability. It is part of a lecture series on the disorder by a leading ADHD researcher.

Greg Kroah-Hartman's Git Merge 2016 talk on how the Linux kernel is developed, how fast it moves, and how git and email workflows keep it manageable. He is the stable kernel maintainer.

Bryan Cantrill presents the ARC (Adaptive Replacement Cache) paper by Megiddo and Modha at Papers We Love. He opens with a survey of caching strategies before digging into the self-tuning LRU/MFU design.

David Brevik's GDC 2016 post-mortem of the original Diablo, covering how it evolved from a turn-based claymation DOS game into the genre-defining action RPG. It includes development anecdotes and lessons learned.

Alexander Bruce's GDC talk on making Antichamber, from working alone in a bedroom to winning acclaim at the IGF. It focuses on the psychological challenge of seven years of solo development.

A Thoughtworks conversation among Martin Fowler, Kent Beck and David Heinemeier Hansson on whether TDD is dead. They discuss the tradeoffs of test-driven development, mocking and where TDD helps or hurts design.

Jim Coplien and Bob Martin debate test-driven development and unit testing in an InfoQ video that grew out of a JAOO 2007 dispute. They also touch on design and architecture.

Ted Young of LightStep proposes trace testing, using distributed tracing data to unify testing and observability. The KubeCon-era talk argues for testing against trace data rather than treating tests and monitoring separately.

Catherine West's RustConf 2018 closing keynote on building a game in Rust and organizing a large codebase. It builds up an entity component system and generational indices step by step.

A Capella Science parody of Despacito that sings through evolutionary developmental biology, explaining how a single cell becomes a body, including body-axis genes and dormant snake leg DNA. It runs about four minutes.

Ronald Minnich of Google explains how UEFI firmware is a large closed attack surface and describes Google's work replacing it with Linux-based boot firmware. It also touches on Intel ME and other security coprocessors.

Scott Wlaschin shows how statically typed functional languages, using F# examples, can model a business domain so that invalid states cannot be represented. The type system acts almost like an instant unit test at compile time.

Derek Slager's Clojure/conj talk argues that ClojureScript is a pragmatic choice for web development. He addresses common objections, recent improvements, tooling and use cases where it shines.

Marco Baringer's tutorial video on SLIME, the Emacs mode for developing Common Lisp. It demonstrates the interactive workflow of working against a live Lisp image.

A GameTrailers walkthrough from E3 2012 of an Unreal Engine 4 real-time tech demo with Epic's Alan Willard. It shows live code changes and hot reloading while the game runs.

Greg Young, who coined CQRS, looks back on a decade of domain-driven design, CQRS and event sourcing at DDD Europe 2016. He discusses where event sourcing applies and how simple its core can be.

Ian Cooper's DevTernity talk revisits Kent Beck's original TDD ideas and shows where misunderstandings crept in. It argues tests should target behaviors through public interfaces rather than implementation details, so suites support refactoring instead of resisting it.

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.

Mark Bastian contrasts top-down object-oriented design with bottom-up, data-oriented design in Clojure. He models a board game as plain data plus small composable functions and compares it with a roughly 22-class OOP version.

David Brevik's GDC 2016 postmortem of Diablo covers how it went from a turn-based claymation DOS concept to a real-time action RPG, plus the story of Blizzard North and development anecdotes.
