In briefChandler Carruth walks through tuning C++ performance, from writing benchmarks to analyzing results on real CPUs and compilers. It focuses on small-scale problems such as loop kernels, data structures and algorithms, and on keeping compilers from optimizing benchmarks away.
In briefSasa Juric explains how to parse a language from first principles without regexes, live-coding a simple parser combinator library in Elixir. It was given at WebCamp Zagreb 2019.
In briefRyan Dahl's first presentation of Node.js at JSConf 2009. He pitches event-driven, non-blocking I/O as the motivation, rather than JavaScript itself.
In briefDan Abramov's talk on the wet codebase, using visualizations to show how removing all duplication too early produces wrong abstractions that are hard to unwind.
In briefArmin Ronacher's EuroPython 2017 keynote examining how the CPython interpreter's leaky abstractions affect language design and how Python could evolve, drawing on JavaScript and Rust experience.
In briefDavid Beazley's workshop screencast builds asynchronous programming in Python from scratch, starting from callbacks and continuations and replacing threads to show how concurrency works underneath.
In briefBruce Waggoner of the Voyager team describes how engineers diagnosed Voyager 1's 2023 loss of telemetry and patched its flight software from 15 billion miles away. The talk covers the spacecraft's architecture and the scarcity of old documentation.
In briefA lightning-style conference talk by Ricardo Signes about the horrors of email: its protocols, formats and decades of accumulated quirks. It is delivered with a humorous horror theme to show why handling email correctly is harder than it looks.
In briefThe first stream in the Emacs From Scratch series, building a custom Emacs configuration from zero while teaching basics. It covers a usable baseline setup and the packages for completion, themes and productivity.
In briefJames Trunk introduces Clojure syntax and thinking, covering its core data structures, immutability, the thread-last macro and live data analysis in the REPL.
In briefVan Jacobson's 2006 Google Tech Talk argues for rethinking networking around named data rather than host-to-host connections. He gives the history and the unsolved problems of the current internet architecture.
In briefKevlin Henney argues that procedural programming never went away despite later paradigms such as OO and functional. He traces the history of structured programming and shows where procedural thinking still lives in modern code and why it matters for readability.
In briefAlan Kay visits Carnegie Mellon's School of Computer Science in 2007 for an informal conversation with faculty and students. He discusses the state of CS education and criticizes mainstream computing.
In briefMario Zechner explains why he built pi, a minimal coding agent, out of frustration with existing agent harnesses. He also discusses how AI agents are straining open source projects and argues for slowing down.
In briefBruce Hauman presents Figwheel, a ClojureScript tool for live, interactive development with hot code reloading. He explains the main ideas, demonstrates how it works, and shares tricks for getting the most out of it.
In briefLearnCode.academy presents a roadmap of web development technologies to learn in 2016 and 2017, spanning front-end, back-end and DevOps tools.
In briefGreg Kroah-Hartman's Git Merge 2016 talk on how the Linux kernel is developed, how fast it moves, and how git and email workflows keep it manageable. He is the stable kernel maintainer.
In briefThe first episode of a screencast series building djb's redo build system from scratch in Haskell. It explains the purpose of redo, writes initial code and sets up a GitHub repository.
In briefRaymond Hettinger's PyBay 2019 talk on the mental habits behind effective programming, drawn from coaching, teaching and StackOverflow. He covers problem decomposition, chunking, managing working memory and getting unstuck.
In briefA podcast episode of Arrested DevOps with Andrew Clay Shafer and Bryan Cantrill, featuring Cantrill's rant on integrity in companies and technology.
In briefA Google I/O 2013 talk by Android audio engineers on why reliable, low-latency audio is hard on the platform. It covers problem areas across the stack, platform work underway and techniques apps can use.
In briefDavid Schachter describes how he made a data-collection Python program run 114,000 times faster, drawing on decades of experience. The talk covers pipelining, cache effects and other optimization lessons.
In briefJosé Valim's ElixirConf US 2023 closing keynote on the foundations of the Elixir type system, covering set-theoretic types and gradual typing with strong arrows.
In briefMatt Godbolt, creator of Compiler Explorer, tours surprising optimizations modern compilers perform, such as turning loops into closed-form sums and using popcount instructions. He explores what the compiler does behind the scenes.
