Cockpit footage of an approach to the Megeve altiport in France that ends in a gear-up landing, with the warning horn audible throughout. Everyone aboard survived and the crew had thousands of flight hours.

Amateur footage from 2014 of small airplanes being lifted and blown around during a microburst. It is a three-minute clip showing how violent the gusts can be.

Real Engineering analyzes whether electric planes are feasible, focusing on battery energy density limits compared with jet fuel. It concludes electric flight works mainly for short ranges.

Michael Steil's 27c3 talk on reverse engineering the MOS 6502 from die shots into a transistor-level simulation, as in the Visual6502 project. It covers going from chip package to a digital model.

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.

AVweb's Paul Bertorelli explains in part two of a series why general aviation has not replaced leaded avgas. He covers industry inertia, bureaucratic delays and the exemption that lets the industry keep using lead.

Cliff Click walks through a small performance example on a modern out-of-order CPU. He covers pipelining, ILP, CISC vs RISC, multicore, and why cache misses and the memory subsystem dominate performance.

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.

Ian Cutress interviews Mike Clark, AMD's chief architect of Zen, about his career since the K5, how Zen began and how CPUs are designed. It also covers the future of AMD.

AVweb's flight trial of Garmin's Emergency Autoland system, which flies a plane to a runway and lands it when the pilot cannot. It is part of Garmin's Autonomi automation on the G3000 avionics.

Footage of Boeing test pilot Tex Johnson barrel-rolling the Boeing 707 prototype over Lake Washington, followed by his explanation of the stunt.

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.
