J. B. Rainsberger argues that large integrated tests are a scam: they are slow, fail opaquely, and give a false sense of coverage. He advocates focused collaboration and contract tests at boundaries instead.

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.

Jason Scott's DEF CON 18 talk tells the history of software piracy over thirty years, centered on the feuds and drama among rival warez groups. It is full of archival material and insider lingo.

Raymond Hettinger's PyBay 2019 talk on the mental strategies he uses when programming in Python, such as chunking, solving a simpler related problem, and repeating tasks manually until patterns emerge. This version is re-synced with the slides.

Neurologist Dr. Matthew Phillips talks at Low Carb Gold Coast 2022 about fasting and ketogenic diets as therapies for cancer and neurodegenerative disease. He focuses on mitochondrial dysfunction and brain energy metabolism.

Chandler Carruth's CppNow 2023 talk describes Carbon as a successor language to C++ rather than a superset, focusing on C++ interop and a path to memory safety in large existing codebases. It explains why Carbon takes a different approach from Cpp2 and Circle.

Glenn Vanderburg presents Cló, a Clojure library that reimplements TeX's core typesetting algorithms as composable functions. He shows what translating procedural, literate-programming code into functional form teaches.

A three-minute clip of Steve Jobs at WWDC 1997 explaining that focus means saying no to many good ideas. It is a short answer about product strategy and its effect on people.

A TEDx talk arguing that battery electric vehicles are not as environmentally friendly as commonly believed and that the rush to adopt them is misguided. TED flagged it as containing claims that lack scientific support.

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.

Josh Kaufman's TEDx talk argues that you can reach practical competence in almost any skill with about 20 hours of focused practice, rather than the 10,000 hours often quoted. He describes how becoming a parent led him to rethink how adults learn, and lays out a short method for rapid skill acquisition.

A 2017 GDC postmortem in which Sid Meier and Bruce Shelley tell how Civilization came together from board game design and sim game experience. They cover its development history and design decisions, including fairness and luck.

Pete Hunt of Facebook and Instagram presents React at JSConf.Asia 2013, explaining its design principles and why they seemed shocking at first. He argues that React separates concerns rather than technologies, and the talk also announces the React Chrome developer tools.

Sandi Metz's RailsConf 2013 talk offers practical guidelines for deciding what to test and how, so tests stay cheap and stable. She argues for testing the public interface rather than implementation and using mocks appropriately.

Moxie Marlinspike's DEF CON 18 talk argues that privacy threats have shifted from centralized state databases like TIA to corporate data collection by companies like Google, despite wins in strong cryptography and decentralization.

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.

Steve Jobs at Apple's 1997 WWDC, shortly after his return, taking developer questions and describing Apple's direction. He discusses the Newton and says to start from the customer experience and work back to technology.

In a TED talk, behavioral economist Dan Ariely uses visual illusions and his research to show that people are less rational in their decisions than they think. He covers defaults, such as organ donation rates, and how choice framing steers decisions.

Clayton Christensen speaks at Google on where growth comes from, covering disruption, market-creating versus efficiency innovation, and jobs to be done. He also touches on measuring your life.

Daniel Stenberg's keynote at FrOSCon 2025 on AI slop attacks on the curl project, with examples of bogus AI-generated security reports. He discusses the toll on maintainers and why various countermeasures don't fit the project.

Andrej Karpathy's keynote at AI Startup School laying out software 1.0, 2.0 and 3.0, with LLMs seen as utilities, fabs and operating systems. It covers LLM quirks, partial-autonomy apps and keeping a human in the generate-and-verify loop.

Sasa Juric explains what makes Erlang and Elixir suited to server-side systems, focusing on the BEAM concurrency model rather than syntax or ecosystem. He demonstrates processes, supervision, and fault tolerance.

Richard Feldman's elm-conf talk on designing models so that bugs from impossible application states cannot occur, using Elm's compiler and types. It demonstrates techniques for making invalid states unrepresentable.

Bret Victor's talk at CUSEC 2012 in which he argues that creators need immediate feedback and should organize their work around a guiding principle. He demonstrates live-coding and animation tools that show results as you type, and describes his own principle that creators must see what they are making.

A long talk by rancher Gabe Brown on turning his North Dakota farm into a regenerative ecosystem using no-till, cover crops and integrated livestock. It covers the five principles of soil health and how they pay off financially.

Richard Cook's short Velocity 2013 talk on resilience in complex adaptive systems, arguing systems operate near the edge of failure and that the surprise is how rarely they fail. He presents a model of how pressures push systems toward failure boundaries.

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.

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.
