Kara Swisher interviews Apple CEO Tim Cook, designer Jony Ive and Laurene Powell Jobs at the 2022 Code Conference. They discuss Apple's history, design, privacy and advertising, and the company's future leadership.

Lesson 1 of fast.ai's Practical Deep Learning for Coders, taught by Jeremy Howard. It takes coders from running code in a Jupyter notebook straight into training a real image model.

Andrej Karpathy builds a GPT from scratch in code, following Attention Is All You Need and GPT-2/3, in about two hours using PyTorch. He connects it to ChatGPT and assumes familiarity with his earlier makemore videos.

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.

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.

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.

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.

Jon Gjengset's roughly four-hour live stream implementing part of a BitTorrent client in Rust, following CodeCrafters' test-guided challenge. He builds from scratch and shows idiomatic error handling along the way.

Andreas Kling live-codes a prototype JavaScript JIT compiler for the LibJS engine used in SerenityOS and Ladybird. He builds a standalone bytecode VM, a simple interpreter, and then a simple JIT in about 80 minutes.

A very long livestream in which Ron Gilbert and Frank Cifaldi look at the making of The Secret of Monkey Island, including its SCUMM source code, which they edit and recompile live.

Bryan Hunter's GigCityElixir 2023 talk on HCA Healthcare's Waterpark system, built on Elixir/Erlang. It describes how the architecture is distributed and fault-tolerant, with a multi-datacenter cluster and runtime code swapping.

Andrej Karpathy builds the GPT tokenizer from scratch, implementing byte pair encoding along with encode and decode. He shows how many odd LLM behaviors trace back to tokenization, and covers Unicode byte encodings along the way.

Emery Berger argues that performance is hard to measure and deliver on modern systems, showing how code layout and link order can swamp optimization effects. He presents tools that evaluate performance more reliably.

Chris Shore of the Centre for Computing History explains how Colossus was built, how it worked, and how it affected the course of World War II. It is an hour-long museum lecture on the codebreaking computer.

A Lex Fridman podcast conversation with the four creators of Cursor, the AI-assisted code editor. They discuss how the editor integrates models into programming workflows, including custom completion models and techniques like speculative decoding to speed up applying edits.

Chris McCord's ElixirConf EU 2023 keynote tracing LiveView's evolution from simple form validation to full apps, with code examples and live demos of what 1.0 will offer.

Freya Holmer's 74-minute video essay on splines, covering Bezier curves, B-splines, derivatives and the different levels of continuity (C0, C1, C2), built with custom animation tools. She notes she did not cover non-uniform splines.

Khalil Estell's CppCon 2024 talk argues C++ exceptions can reduce binary size in firmware. He digs into how exceptions work and how to shrink their code footprint on embedded platforms.

Tom Scott makes the difference between a million and a billion dollars tangible by using distance on a road trip instead of volume. The drive makes the scale of a billion intuitively felt.

Lex Fridman interviews Mark Zuckerberg in the metaverse, with both appearing as photorealistic avatars from separate locations. They discuss Meta's AI, VR and the future of avatars.

A Lambda Days keynote by Simon Peyton Jones and Tim Sweeney introducing Verse, Epic's functional logic language for the metaverse. It covers existential variables, unification and expressions yielding multiple values.

Andrej Karpathy's first Neural Networks: Zero to Hero lecture, which builds micrograd, a tiny autograd engine, from scratch in Python. It explains backpropagation and neural network training step by step, assuming only basic Python and some high-school calculus.

Jeremy Howard's 90-minute practical tour of language models. It covers how they work, GPT-4's capabilities and limits, using the OpenAI API, code writing, data analysis and fine-tuning.

A long George Hotz livestream in which he explores the coronavirus genome and molecular biology from scratch using a browser and Python, hacking on the science in real time.

In this first Crust of Rust episode, Jon Gjengset live-codes an example that needs multiple explicit lifetime annotations. Along the way he covers string types and generics over a custom trait.

Lex Fridman interviews Douglas Lenat, founder of Cyc, a decades-long project to encode common-sense knowledge and reasoning for AI. They discuss symbolic AI and how it may complement neural networks.

Joe Armstrong's Strange Loop 2013 talk on building large scalable systems from small isolated parallel components. It covers detecting and correcting errors at run time, changing code while it runs, and how Erlang embodies these principles.

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.

A nearly three-hour Joe Rogan interview with Meta CEO Mark Zuckerberg, covering Meta's products, AI, smart glasses, and his views on culture and company direction. The conversation is wide-ranging and long-form.
