Jack Moffitt presents the architecture of Servo, Mozilla's experimental browser engine written in Rust, focusing on parallelism across cores, GPUs and SIMD and the safety properties gained from Rust.

Simon Knowles, co-founder and CTO of Graphcore, talks about "intelligence processors", chips designed specifically for machine learning. The talk was given at the RAAIS 2017 summit and covers Graphcore's architecture.

Jacob Geller's video essay examines how architecture in schools and in video games, such as cover shooters, is shaped by violence. It touches on brutalism, campus policing and protests.

Sophie Wilson, designer of the ARM instruction set, discusses the future of microprocessors, including the economics of scaling below 28nm and why much of a chip must stay powered off.

Dave Jaggar, who defined much of the ARM architecture, recounts how Acorn's near-extinction led to ARM, including the history of Thumb, StrongARM, and the Austin team.

A 1979 BBC Nationwide report asking whether word processors and networked microprocessors could end office commuting. It shows early word processing and a woman working from home, with surprisingly prophetic predictions.

David Ditzel of Esperanto Technologies presents their massively parallel, energy-efficient RISC-V processors at the 7th RISC-V Workshop in 2017. It covers the high-performance many-core design aimed at machine learning.

A short Conan segment in which George R. R. Martin explains that he writes his Game of Thrones books on WordStar 4.0 on a DOS machine.
