David Beazley's PyCon India closing keynote, in which he live-codes a stack machine and grows it into an interpreter that runs WebAssembly, then uses it to play a Rust-written game. It requires no prior WebAssembly knowledge.

Dylan Beattie's NDC London talk on code written for art, fun and curiosity rather than utility. It includes quines, live music programming with Sonic Pi, and a memorable closing.

Casey Muratori's University of Twente guest lecture is a case study in how straightforward code can cut thousands of lines and tens of seconds of runtime down to a few dozen lines running in under a second. It uses concrete examples to show why software is often an order of magnitude slower than it should be.

Bob Beck of OpenBSD describes the first month of LibreSSL, the fork aimed at cleaning up OpenSSL, including oddities found in the code base and why it was cleaned rather than audited cryptographically.

Sean Parent's CppCon 2015 talk on better use of standard containers and the goal of having no incidental data structures. It argues that proper containers can greatly simplify code.

Scott Meyers explains how CPU caches work and why they matter for performance, covering cache levels, access speeds, associativity, and effects in multithreaded code. The focus is C++ and cache-aware, data-oriented programming.

John McCall of Apple's Swift team presents at CppNow 2023 on introducing a memory-safe successor language into large C++ code bases. He argues incremental improvement of C++ hits hard limits and explains Swift's C++ interoperability for gradual migration.

Bob Beck of OpenBSD gives a BSDCan 2014 talk on the first month of LibreSSL, the OpenSSL fork. He explains why they forked, what they removed, and examples of the problems found in the OpenSSL code base.

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.

A tool-assisted speedrun of Ocarina of Time at Summer Games Done Quick 2022, using TASBot and arbitrary code execution to reach an alternate ending in about 53 minutes. The run is introduced by its creators and followed by an interview.

Pat Wyatt, a veteran game programmer who worked at Blizzard and ArenaNet, speaks at HandmadeCon 2015 in a conversation with Casey Muratori. He discusses network code and architecture in games he worked on, including mistakes on Diablo and the success of Guild Wars.

Lex Fridman interviews Donald Knuth about algorithms, complexity, The Art of Computer Programming, and his work habits. The conversation covers his approach to verifying algorithms and how he organises his time.

Jon Gjengset spends about three hours livecoding complex changes in a Rust codebase with agentic AI tools, testing his hypothesis that AI is weak at non-pattern work. He documents where Claude Code helps and where it struggles.

Kevlin Henney revisits structured programming, from Go To Statement Considered Harmful to block-structured code and object orientation. He argues it still matters for how we write code today.
