A short clip from Udacity's Web Development course in which Reddit co-founder Steve Huffman describes how Reddit grew early on. He explains seeding the site with content from fake accounts.

A five-minute demo of a live ClojureScript game editor by Chris Granger. It is based on Bret Victor's demo from the Inventing on Principle talk, with code changes reflected instantly in the running game.

A short demo of interactive AI live painting in Krita using the Stable Diffusion plugin, where canvas changes update the generated image immediately. It uses an LCM sampler for speed and needs a high-end GPU for the interactive feel.

A short PCWorld news clip from WWDC 2007 in which Steve Jobs announces Safari as the development platform for iPhone apps. Developers could build web apps with access to calling, maps and email.

A Curry On talk by Lars Bak, known for V8 and Dart, on building a secure and robust IoT development platform. It discusses language and VM design choices for small devices.

Jeremy Howard defends Jupyter notebooks as a serious development environment, especially when paired with nbdev. He responds directly to Joel Grus's talk about why he dislikes notebooks, and contrasts REPL-style and notebook-style work.

Fons van der Plas introduces Pluto.jl, a reactive notebook for Julia that tracks references between cells and re-runs affected cells when code changes. The talk was given at JuliaCon 2020.

Will Wilson explains autonomous testing: using deterministic simulation and fuzzing, building on FoundationDB's approach, to test software continuously. It sets out the ideas behind his later company Antithesis.

Dan Liebgold of Naughty Dog gives a RacketCon 2013 keynote on using Racket in PlayStation 3 game development. He explains the Racket-based DSLs used for game data and scripting, which replaced the studio's earlier GOAL-based toolchain.

Sean Parent of Adobe argues that object-oriented frameworks ultimately fail to deliver scalable, high quality software and proposes combining generic and declarative programming instead. It draws on Stepanov's Elements of Programming.

TJ DeVries coins the term PDE (Personalized Development Environment) to describe editors like Neovim that you shape to your own workflow. He contrasts this with out-of-the-box IDEs and discusses why customizable tools appeal to developers.

Geoff Hinton's 2010 Google Tech Talk on deep belief networks, learning layers of representation one at a time from unlabeled data, and extending them with multiplicative interactions.

Ted Young of LightStep proposes trace testing, using distributed tracing data to unify testing and observability. The KubeCon-era talk argues for testing against trace data rather than treating tests and monitoring separately.

Michael Hendricks of PriceCharting shares tricks and pain points from running Prolog in production for 18 months at Strange Loop. It argues Prolog is a productive modern language beyond logic puzzles, and includes a demo of changing code mid-execution.
