Scott Jenson, a veteran UX designer formerly at Apple and Google, argues that the 'UX/UI' split pits programmers against designers and narrows ambition in open source. He makes the case that desktop UX has stagnated and that open source projects could lead experimentation beyond current interaction models.

Vsauce explores whether people in past decades really looked older than people of the same age today, or whether photographic and cultural factors make them seem so. It draws on old photos, yearbooks and perception research.

Evan Czaplicki, creator of Elm, examines how programming languages are funded. He looks at where compiler engineers' salaries come from, why Go has about 5 engineers while Dart has about 30, and how this limits language design.

Tantacrul explains how he and engraver Simon Smith designed the free music notation font for MuseScore 3.6. It draws on the history of the SCORE notation application by Leland Smith.

Mario Zechner explains why he built pi, a minimal coding agent, out of frustration with existing agent harnesses. He also discusses how AI agents are straining open source projects and argues for slowing down.

Matt Mullenweg joins ThePrimeagen's Twitch stream to discuss the WordPress and WP Engine dispute, including trademark use and contributions.

Dwarkesh Patel interviews Andrej Karpathy on why reinforcement learning is flawed, why AGI may blend into steady GDP growth, why self-driving took so long, and the future of education. The conversation runs about two and a half hours.

Technology Connections explains why brown is not a spectral color but a context-dependent perception, essentially dark orange seen against brighter surroundings.

Louis Rossmann explains why he stopped using GrapheneOS, describing his interactions with its lead developer Daniel Micay. It includes chat logs shown in the video.
