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.

Rich Hickey's talk at Clojure's tenth anniversary on the kind of programs Clojure is designed for. He argues for situated programs that deal with changing requirements, and for dynamic typing and data over static types.

Rich Hickey's keynote on software versioning, arguing that breaking changes are the real problem and that libraries should only grow by providing more and requiring less. It critiques semantic versioning and ties into Clojure spec.

Rich Hickey's Strange Loop 2011 keynote separates 'simple' (not intertwined) from 'easy' (familiar or near at hand) and argues that software complexity comes from complecting things. It offers a vocabulary for judging designs and abstractions.

Rich Hickey's keynote at RailsConf 2012, a close sibling of his 'Simple Made Easy' talk. He distinguishes simple (not intertwined) from easy (familiar), and argues that software complexity comes from complecting things, with Rails-specific examples including large gem collections.

Rich Hickey introduces transducers in Clojure, a way to make map, filter and similar algorithms composable independent of the data source. This avoids duplicated implementations and intermediate collections across sequences, channels and streams.

K Lars Lohn's PyCon 2016 keynote weaves together music theory, programming, biking road trips and fractals. It is a personal, wide-ranging talk rather than a Python how-to.

Rich Hickey's talk on time, state, identity and values, arguing that mutable object-oriented modeling fits the world poorly. It lays out the thinking behind Clojure's approach to data and change.

Matt Adereth's Clojure/conj talk covers the history of keyboards and how he used Clojure generating OpenSCAD to design and build his custom Dactyl ergonomic keyboard, including 3D printing and laser-cut parts.

Rich Hickey, creator of Clojure and designer of Datomic, gives a JaxConf 2012 talk that takes apart traditional database architecture. He presents a different way to think about databases and explains the reasoning behind Datomic's fact-based design.

Erlang co-creator Joe Armstrong's Code BEAM SF 2018 keynote revisits good ideas from the history of computing that were dropped, and asks which should be revived. It also touches on Erlang and Elixir.

Patricia Aas's EuroBSDCon keynote is about ethics for people who build software, covering how the tech industry got to its current state and what engineers can do about it. It steps back from technical detail to the bigger picture.

Kathy Sierra's Fluent 2015 keynote on the one metaskill for developers: the ability to come up to speed quickly and stay there. She covers how people learn, cognitive resources versus willpower, and building skill.

John Carmack's keynote at Facebook Connect 2021, where he speaks candidly about VR, Quest, and Meta's metaverse plans. He pushes back on hype and discusses retention and latency.

Rich Hickey introduces Clojure to the NYC Java Study Group in the first of a two-part talk. It covers reader syntax, core data structures, code-as-data, evaluation, special operators, functions, macros and sequences, assuming no Lisp background.

RustConf 2020 closing keynote by Sian Griffin that dives into Pokemon Blue glitches, notably Missingno and arbitrary-code-execution tricks. It uses them to explain how memory unsafety works and how memory-safe languages like Rust prevent such bugs.

Keynote from the 2016 Dart Developer Summit introducing Flutter, Google's toolkit for building mobile apps from one codebase. It shows early demos aimed at native look and feel.

Peter Munch-Ellingsen explains at NimConf 2021 why he wrote his own keyboard firmware in Nim instead of using QMK or Arduino. He shows that the resulting firmware is very small.
