Martin Kleppmann argues that databases are global shared mutable state and proposes treating them as an ever-growing log of immutable facts. Derived data such as caches, indexes and views is then built by stream processors like Apache Samza. The talk draws on Kafka and LinkedIn's experience with commit logs.

A 38C3 talk on how advanced chips are made, centered on EUV lithography and the global supply chain behind it. It covers technical challenges from raw materials to finished chips and the geopolitical weight of semiconductors.

A full-day recording of the University of Utah computer science department's 50th anniversary event with panels, keynotes and talks by alumni and pioneers. It includes Ivan Sutherland's presentation on single flux quantum electronics.

Hans Rosling's TED@Cannes talk uses boxes and animated data graphics to show how world population will grow to about 9 billion. He argues that raising living standards for the poorest is what reduces population growth.

Cindy Gallop gives a 4-minute TED2009 talk arguing hardcore pornography has distorted how young men think about sex. She introduces her website MakeLoveNotPorn as a response.

A linux.conf.au 2013 talk by a Wayland developer who previously worked on X, telling the history of X and why Wayland was created. It covers X's hardware abstraction and architecture and why they became problematic for modern graphics.

Trevor Paglen's 30C3 talk on photographing and documenting the secret state, including CIA flights, spy satellites and military sites, to reveal the geography of covert programs.

Andrew Kelley's Zig SHOWTIME talk on an experiment to ship static Linux executables that can do graphics and gaming, followed by an interview. It covers the problems of Linux binary stability, dynamic linking and the graphics ABI.

Anna Rosling Rönnlund presents Dollar Street, a project photographing homes in dozens of countries, from stoves to beds to toilets, and sorting them by income. She shows how data visualization can change how we see the world.

Ahmon Dancy of Franz Inc explains low-level programming in Common Lisp, including off-heap data structures used in AllegroGraph to manage memory outside the garbage collector.

A Graphics Programming Conference talk on how the game Tiny Glade renders meadows, trees and player-built castles. It covers real-time global illumination, tilt-shift depth of field, stable shadows with continuous time of day, ray marching and GPU-driven rendering on old hardware.

A HOPE09 talk on how modern computer chips are manufactured, from 22nm transistors to ultra-clean fabs and the tricks used to pattern tiny features with light. It frames chipmaking as hacking electrical engineering and physics.

Daniel Stone, a longtime X and Wayland developer, explains at linux.conf.au 2013 why X11's design became untenable and what motivated Wayland. The talk walks through X's history and accumulated cruft.

Fons van der Plas introduces Pluto.jl, a reactive notebook for Julia that tracks references between cells and re-runs affected cells when code changes. The talk was given at JuliaCon 2020.

X.Org developer Daniel Stone explains the history and technical limits of the X Window System and why Wayland was created, debunking myths from forum comments. He covers topics such as network transparency and blocking calls.

Hans Rosling's TEDxSummit talk asks whether some religions have higher birth rates and how that affects population growth. He charts data across time and religions and reaches a surprising conclusion about fertility.
