Branch Education walks through a semiconductor fab and the dozens of steps used to turn silicon wafers into microchips, with 3D animation. It covers lithography, deposition and etching at a high level.

Johnny Harris investigates why McDonald's ice cream machines are so often broken, covering the Taylor machines, the repair restrictions on franchisees and the Kytch workaround device.

Matthias Wandel tests old and new code on a range of PCs, including a new mini PC, to measure how much faster modern hardware really is. He also shows optimization techniques such as branchless code, with benchmark programs on GitHub.

An 8-minute National Geographic short film about David Bamberger, who bought 5,500 overgrazed acres in the Texas Hill Country and restored the land and its aquifers over about 50 years.

Andrei Alexandrescu's CppCon 2019 talk revisits sorting, showing how branchless tricks, hybrid strategies and a cost metric can speed up std::sort-style algorithms on modern hardware.

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.

Chandler Carruth shows how to squeeze more performance out of already-optimized C++ code, covering how the CPU executes it. The talk goes into pipelining, branch prediction and speculative execution using benchmarks.

Lex Fridman interviews chip architect Jim Keller about the future of computing, AI, life and consciousness. Topics include CPU design, branch prediction and why imperfect designs often win.

Matt Godbolt builds a toy path tracer in C++ in three different styles and compares them on clarity, testability, compile time and run-time performance. The talk was given at CppCon 2019.

A 36-minute animated deep dive from Branch Education into how DRAM works. It shows how memory connects to the CPU and how billions of bits are stored in nanoscale capacitor cells. It also covers why DRAM sits between SSDs and the processor.

Branch Education's animated deep dive into ASML's EUV photolithography machine and how it prints nanometer-scale transistors onto chips. It covers the system's components and the process of chip manufacturing.

Branch Education explains how Starlink works, from the ground dish and satellites to phased-array beam steering and data routing. Animations cover how a beam stays connected to a satellite moving at 27,000 km/h.

A long talk by rancher Gabe Brown on turning his North Dakota farm into a regenerative ecosystem using no-till, cover crops and integrated livestock. It covers the five principles of soil health and how they pay off financially.

Farmer Gabe Brown talks about how he rebuilt the soil on his ranch using no-till farming, cover crops, and grazing animals. The talk was recorded at a sustainable agriculture symposium in Idaho in 2014.

Daniel Lemire's QCon talk on how simdjson parses gigabytes of JSON per second. It covers SIMD vectorization, branch prediction and the lessons learned building a fast parser.

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.
