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.

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.

Jack Rusher's Strange Loop 2022 talk argues that most programming languages are still designed around punchcard-era assumptions. He makes the case for live, interactive programming environments, drawing on Lisp, Smalltalk and REPL-driven development.

Hans Rosling uses the Gapminder animated-data tool to debunk myths about world development, with sportscaster-like energy. It shows trends in health, income and child survival across countries.

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.

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.

Valve's two-hour documentary for Half-Life 2's 20th anniversary, with team members discussing development, nearly running out of money, being hacked, the publisher lawsuit and the birth of Steam.

John Ousterhout's Netdev 0x16 keynote arguing that nearly every aspect of TCP is wrong for the datacenter, from connections and streams to reliable delivery and congestion control. He presents the case for a replacement protocol.

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.

Not Just Bikes explains how an electric bakfiets (Dutch cargo bike) replaced the family car after a move back to Canada, saving thousands of dollars. It shows how much it can carry, including kids and groceries.

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.

Jeremy Howard defends Jupyter notebooks as a serious development environment, especially when paired with nbdev. He responds directly to Joel Grus's talk about why he dislikes notebooks, and contrasts REPL-style and notebook-style work.

A short demo of Code Bubbles, an IDE interface built around editable code fragments in bubbles instead of files. It was a research prototype for Java development.

Zach Oakes explains why Clojure suits making games at runtime, so designers can experience their work as they build it. He combines abstract discussion with live demonstrations, drawing on his play-clj library and Nightmod tool.

Glenn Vanderburg argues at the O'Reilly Software Architecture Conference that software development is an engineering discipline, even if immature. He contends the discredited body of knowledge called software engineering has led people to wrongly reject the label.
