A short demonstration of radioteletype (RTTY), a digital communication mode used in amateur radio, showing what the signal sounds like.

Jason Scott of Archive Team describes how a loose band of volunteers rushes to copy sites like Geocities, Friendster and Yahoo Video before their owners delete them. The talk covers the tactics they use and the argument that this data is history worth saving.

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.

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.

Moxie Marlinspike's DEF CON 18 talk on changing threats to privacy argues that surveillance arrived through convenient services and network effects, so opting out is not a real solution. It also includes his framing of getting social democracy rather than the fascism people feared.

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.

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.

Dan Geer's Black Hat 2014 keynote argues that cybersecurity is a matter of power and policy rather than wishful thinking. He covers surveillance, the vulnerability market, software liability and privacy as the capacity to misrepresent yourself.

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.

Emily Shea explains how repetitive strain injury pushed her to program by voice using speech recognition (Talon), and gives a live coding demo. She argues voice-driven development can be pain-free, efficient and enjoyable.

Titus Winters' CppCon 2017 talk argues for C++ and Google's Abseil to be maintained as a live at head language, relying on testing and automated tooling rather than never changing or promising no compatibility. It covers Hyrum's law and the limits of semantic versioning.

A five-minute lightning demo of VisiData, a terminal tool for exploring and manipulating data. It uses two months of NYC 311 complaint data to drill down, plot points on a virtual map and save selected rows.

Dirk Hohndel explains why the Subsurface dive log project migrated from Gtk to Qt, the obstacles encountered, and advice for other applications frustrated with Gtk. It is a linux.conf.au 2014 talk.

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.

Paul Turner of Google presents kernel interfaces for user-level scheduling of real threads, aiming at a uniform synchronous programming model across C++, Java, Go and Python. It introduces the switchto-style system calls behind Google's fibers.

Andrew "bunnie" Huang examines how realistic hardware supply chain attacks are, from rogue insiders to nation states, in the wake of the Bloomberg Businessweek report. He explains how undocumented components could be hidden on boards and how hard they are to spot.

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.

Steve Yegge records himself working in Emacs and shows off about a dozen features in a roughly 45-minute screen capture. It is an informal, enthusiastic tour rather than a structured tutorial.
