Timothy Roscoe of ETH Zurich delivers the joint USENIX ATC/OSDI 2021 keynote arguing that operating systems must reckon with modern hardware, which is a heterogeneous collection of processors, firmware and coprocessors rather than a simple machine. It shows how much runs below and beside Linux.

Zig creator Andrew Kelley justifies why Zig exists and tours its distinctive features, including C interoperability and comptime, along with what people had built and what 1.0 would bring. It was given at Philly ETE 2019.

Jason Scott of textfiles.com tells the story at DEFCON 17 of being sued for two billion dollars by a scammer who plagued him and others for over a decade. The talk is tragic and funny, covering what he learned about misleading schemes.

John Rauser's Strata 2014 keynote argues that programmers can learn statistics quickly by simulating random processes and shuffling data. He explains p-values through resampling rather than formulas.

Jonathan Blow talks at Gamelab 2018 about the design decisions behind Jai, the programming language he is building for game programmers. He covers low-friction development, quality of life and the effects of compile times.

A Strange Loop 2019 talk by Aaron Cummings on the computing systems aboard Voyager 1 and 2, which control the spacecraft and record and return data decades after launch in 1977.

Jake Vanderplas's PyCon 2016 talk shows how sampling-based methods such as simulation, shuffling and bootstrapping make statistics intuitive. His pitch is that if you can write a for-loop, you can do statistics.

Neil Fraser of Google presents Differential Synchronization, the algorithm behind MobWrite, for keeping multiple copies of a document in sync in real time. The talk argues the approach is robust, convergent and efficient.
