John Carmack's long QuakeCon 2012 keynote, a free-ranging talk covering software engineering, game platforms, game streaming, and his early head-mounted display and VR work.

Ben Eater explains how a USB keyboard communicates, covering the electrical interface, bit and packet encoding, packet contents, and a comparison with PS/2.

Ben Eater explains how the PS/2 keyboard interface works, covering its clocked serial protocol and scancodes. He builds up the hardware-level understanding needed to read keypresses.

A satirical Onion News Network piece announcing the 'MacBook Wheel', a laptop with no keyboard where users type by spinning and clicking a wheel. It parodies Apple product launches and minimalist design.

Rich Hickey presents an extensive introduction to Clojure at the Boston Lisp meeting, assuming prior Lisp knowledge. It covers the language's design decisions relative to other Lisps.

A fan-made music video for Jonathan Coulton's song 'Code Monkey', about the life of a programmer, using World of Warcraft footage. It was made by Mike Spiff Booth.

An over-the-shoulder view of StarCraft 2 pro player Sound at a WCS qualifier, showing his monitor, keyboard and mouse. It shows his very fast actions per minute in real time.

Rich Hickey's Strange Loop 2011 keynote distinguishing 'simple' (not intertwined) from 'easy' (familiar or near at hand). It argues that software complexity comes from complecting things and that we should pick simple constructs.

Rich Hickey's JaxConf 2012 keynote examines what values are and why immutable values matter as information systems grow more complex and data gets bigger. It contrasts places with values and builds the case for immutability.

Rich Hickey's Clojure/Conj 2018 keynote argues that Maybe/Option types and rigid type signatures are a poor way to model data that changes over time. He builds the case around optionality, schema growth and compatibility, and presents the ideas behind Clojure spec as an alternative.

James Mickens's humorous USENIX Security keynote argues that improving security and trusting opaque technology like machine learning is far harder than the industry admits.

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.
