Scott Chacon introduces Git by showing what happens under the hood for basic commands: staging, committing, data storage, branching, merging and pushing. He contrasts it with Subversion and shows history viewing with log.

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.

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.

The author of lazygit demos 15 features of his terminal UI for git, such as staging individual lines and easier rebasing, aimed at making common git tasks simpler.

GitHub interviews Linus Torvalds on twenty years of Git, from its creation in about ten days as a Linux kernel tool to its role in modern software development. He discusses technical decisions, community contributions and the project's philosophy.

A demo of Deldo, an Emacs package that lets Emacs hooks trigger vibration events on computer-controllable sex toys. It is an absurd teledildonics project that is half performance art.

Martin von Zweigbergk presents Jujutsu (jj), a Git-compatible VCS with undo, anonymous branches, first-class conflicts, automatic rebasing, and the working copy as a commit. He also covers plans at Google.

A 1953 US Navy training film explaining the basic mechanisms in mechanical fire control computers aboard ships. It shows how gears, differentials and cams solved mathematical problems in permanent mechanical form.

A 1953 US Navy training film on the basic mechanisms in fire control computers: shafts, gears, cams and differentials. It shows how these mechanical parts compute ship and target firing solutions.

Rich Hickey's keynote on software versioning, arguing that breaking changes are the real problem and that libraries should only grow by providing more and requiring less. It critiques semantic versioning and ties into Clojure spec.

The full 1984 interview with Yuri Bezmenov, a former KGB operative, in which he lays out four stages of ideological subversion. It is a long interview with G. Edward Griffin.

A special lecture from MIT's Private Pilot Ground School in which Lt. Col. Randy Gordon, a fighter and test pilot, describes F-22 flight controls. Topics include thrust vectoring, the pilot command system and how software handles failures.

Part one of Sandia National Labs' first-person documentary on the use control, detonation safety and survivability of US nuclear weapons. It covers nuclear sharing in NATO and how control of use was separated from possession, leading to the always/never problem.

A short demo of an open-source Krita plugin that uses Stable Diffusion to generate and edit images in place. It adds ControlNet scribble and line-art support. You select an area, push a button, and new matching content appears.

An American Airlines training video by Captain Warren VanderBurgh on control malfunctions and flight instrument anomalies. It discusses real incidents such as runaway trim and instrument failures and how crews should respond.

Valve's short video on building the Steam Controller on a heavily automated assembly line, which the company designed itself. It shows the robotic manufacturing process and US final assembly.

Terry Davis, author of TempleOS, demonstrates his SimStructure physics simulator and builds a PID controller using math from Numerical Recipes in C. The description notes PID controllers are used in everything from rockets to espresso machines.

Fully Charged gets an exclusive first drive of the Porsche Taycan, running 0-200 km/h launch control repeatedly. It covers the car's twin-motor 800-volt specs, claimed range and fast charging.

A TU Wien control-systems demo in which a triple pendulum on a cart is swung up and stabilized using constrained feedforward plus optimal feedback control. It accompanies a 2013 Automatica paper.

Ben Heck modifies a keyboard with magnets, Hall effect sensors and an Xbox controller so the WASD keys give analog control. He walks through the hardware build.

A 21-minute animation showing how a sphere can be turned inside out without creases or tears, known as sphere eversion.

Evan Czaplicki's Strange Loop 2014 talk surveys the many formulations of functional reactive programming and how they relate historically and theoretically. It then shows how Elm's variant enables hot-swapping and its time-traveling debugger.

Rachel Potvin describes the scale of Google's codebase and its custom monolithic source repository. She explains the reasons for the monorepo model, the tooling that makes it workable, and its tradeoffs.

Ashley Feniello demonstrates VimSpeak, a voice-controlled interface for Vim inspired by Tavis Rudd's voice programming talk. The demo includes working through a VimGolf challenge by speech.
