Cliff Click of Azul Systems gives a Google Tech Talk on running Java business applications on a machine with about a thousand cores. He covers hardware and software codesign, including garbage collection hardware and the JIT.

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.

Andrew Ng presents unsupervised feature learning and deep learning, showing how algorithms can learn representations from unlabeled data instead of hand-designed features. He gives examples in vision and audio, including visualizations of features learned by successive layers.

A DEF CON 29 talk by Richard Henderson about encoding the EICAR antivirus test string into QR codes and barcodes and scanning them at real systems. Many systems that do not expect such input misbehave or collapse, including a parking garage system.

David MacKay, scientific advisor to the UK energy department, gives a Harvard talk on sustainable energy at macro and micro scale, drawn from his book Sustainable Energy Without the Hot Air. It stresses the land area renewables require.

Raph Levien presents his new Rust GUI framework, built on data-oriented design and ideas from entity component systems, for the Xi editor. He weighs the approach against alternatives and discusses pros and cons.

Sebastian Markbage explains how React is moving toward a minimal API surface by leaning on language features and patterns instead of dedicated framework APIs. He also touches on JSX and syntax proposals for future JavaScript.

John Wiegley's BayHac 2017 talk walks through Haskell lenses by example, showing many practical uses beyond simple record access. It is aimed at people who want to become productive with the lens library.

Dan Abramov live-codes hot reloading with time-travel debugging at React Europe 2015, debuting Redux and its devtools. The slides themselves are driven by application state.

Liz Rice live-codes a minimal container runtime in a few lines of Go at GOTO Amsterdam 2018. She explains namespaces, control groups and what a host knows about its containers.

A 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.

Andrew Sorensen's OSCON 2014 keynote in which he live-codes generative music on stage using his Impromptu environment while narrating his computational and musical choices. It imagines concert programmers as a performing art.

Karla Burnett presents real phishing campaigns run against a Bay Area tech company, including conversion rates and how existing protections were bypassed. She argues for evidence-based techniques to prevent credential phishing, not just mitigate it.

Nathaniel J. Smith's PyCon 2018 talk introducing Trio, a Python concurrency library designed around usability and structured concurrency. He live-codes a problem and analyzes pitfalls in other async libraries.

Robert Smith of Rigetti Computing talks at a Bay Area Lisp and Scheme meetup about using Common Lisp for quantum computing. He covers the technical, sociological and psychological sides of working across disciplines.

Tom Dale explains the internals of the Glimmer VM, Ember's rendering engine, which compiles templates to opcodes. The talk includes a performance benchmark demo.

An excerpt from a Bay Area Rust meetup on Servo's WebRender, which renders CSS display lists on the GPU at very high frame rates. It explains the approach and demos rendering at around 500 FPS.
