Ken Shirriff walks through how to reverse engineer integrated circuits from die photos, using famous chips as examples, in a Hackaday SuperConference talk.

Short Curious Droid video on why NASA could not simply rebuild the Saturn V's Rocketdyne F-1 engine for the SLS boosters. It explains that the engines were hand-tailored and that much of the know-how was never documented, so the blueprints were not enough.

Mozilla's short demo of Unreal Engine 3 running in Firefox, ported by Mozilla and Epic in four days using Emscripten and asm.js.

Practical Engineering explains Mechanically Stabilized Earth, where layers of reinforcement make soil strong enough to hold heavy loads, shown with a sand structure supporting a car. It notes that MSE walls are everywhere in infrastructure.

Epic Games shows how LED walls can provide both virtual backgrounds and real lighting, letting scenes be captured in camera in a single pass with Unreal Engine.

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.
