A demo of writing technical documents in Emacs Org mode using org-babel, so that code blocks and generated content stay consistent when things change. The author shares the demo files and his dotfiles.

A three-minute Emacs Rocks screencast by Magnar Sveen demonstrating paredit, which edits Lisp code structurally as a tree of s-expressions rather than characters.

A three-minute Emacs Rocks screencast demonstrating Magit, the Git interface inside Emacs, including staging and other everyday operations.

John Kitchin shows how Emacs org-mode with Python lets researchers combine narrative, math, figures and executable code in one document. It exports to LaTeX, HTML and PDF, and he used it for papers and e-books.

Elias Martenson presents his Emacs-based workflow for building a web application (the Potato chat platform) with Common Lisp on the backend and ClojureScript on the frontend. He demonstrates SLIME, Paredit, CIDER and debugger-driven interactive development. The talk is 79 minutes and was given at Emacs SG.

Perry Metzger, an Emacs user since 1983, gives a talk on why he has used one editor for decades. It mixes history, philosophy and speculation about Emacs's future, and teaches some Emacs fundamentals.

Harry Schwartz gives a roughly hour-long tour of Emacs Org mode as an outliner, task manager, markup language and agenda tool. He demonstrates how he uses it for documents, presentations and todo lists.

Tavis Rudd describes how RSI forced him to program by voice, and shows the Python and Emacs Lisp system he built with voice recognition. A live demo creates and deploys a small system without touching the keyboard.

Marco Baringer's tutorial video on SLIME, the Emacs mode for developing Common Lisp. It demonstrates the interactive workflow of working against a live Lisp image.

A 1993 VHS demo of Lucid Energize, a database-backed, incremental C/C++ programming environment built on XEmacs. It shows features like incremental compilation, live debugging and hyperlinked output.

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.

Tudor Girba's Curry On! 2019 talk on moldable development, the idea that developers should build custom tools and views for each software system they work on. It draws on the Pharo and Glamorous Toolkit environments.

Sandi Metz takes an ugly section of conditional code and refactors it into a few simple objects, bridging object-oriented theory and practice. The talk includes her take on the Gilded Rose refactoring kata and the idea that duplication is cheaper than the wrong abstraction.

Will Wilson of FoundationDB explains how the team tested their distributed database using deterministic simulation. By running the whole system in a simulator with injected faults and reproducible seeds, they could find rare concurrency and network bugs.

Ian Cooper's DevTernity talk revisits Kent Beck's original TDD ideas and shows where misunderstandings crept in. It argues tests should target behaviors through public interfaces rather than implementation details, so suites support refactoring instead of resisting it.

Bret Victor's talk at CUSEC 2012 in which he argues that creators need immediate feedback and should organize their work around a guiding principle. He demonstrates live-coding and animation tools that show results as you type, and describes his own principle that creators must see what they are making.

Rafal Dittwald's Clojure/north talk shows how to move from writing Java-style code in Clojure to thinking in data-driven, functional terms. He walks through a JavaScript example, refactoring imperative code step by step into a functional core.

Bryan Cantrill's GOTO Chicago 2017 talk on debugging production systems under pressure, centered on the incident where an operator's mistyped command rebooted an entire Joyent datacenter. It covers human factors, automation and architecture.

Emery Berger explains why performance is hard to measure and deliver on modern hardware, showing how code layout and alignment can swamp optimization effects. He presents Stabilizer for statistically sound evaluation and Coz, a causal profiler.

Russ Cox gives a 23-minute tour of the Acme text editor from Plan 9, showing its mouse-driven interface, executing commands from text, and its filesystem-based interface to other programs.

Gil Tene of Azul Systems explains common pitfalls in measuring latency and response time, including why averages mislead and the problem of coordinated omission. He introduces open source tools like HdrHistogram for better measurement and reporting.

Gary Bernhardt's RubyConf 2012 talk on testing in isolation without mocking everything. It goes through behavior versus data, mutation versus immutability, and how a functional core with an imperative shell yields natural isolation and parallelism.

Linus Torvalds gives a Google tech talk on git, the source control system he created two years earlier. He argues for distributed version control over centralized systems such as CVS and Subversion.

A thoughtbot meetup talk by Max Cantor on getting most of what popular plugins provide using only built-in Vim features. It covers autocomplete, file jumping, filesystem navigation, build integration and snippets, with slides and a vimrc available.

A lecture from MIT's Missing Semester course covering version control with git. It builds up git from its data model rather than from commands.

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.

Ruby developer Avdi Grimm gives a seven-minute tour of Pharo Smalltalk's development environment, focusing on tools like search-by-example and the integrated, live coding experience.

A Linux.conf.au 2013 talk that explains git's internal model using a playful, toy-based approach. It presents git operations as operations on a graph of commits, aimed at people who find git confusing.
