AI and agents

The Future is for Everyone: The Path to a Positive AI Future by Mark Zuckerberg — his case for putting superintelligence in everyone's hands instead of a few institutions.

The Shape of Things to Come, Part 1: The Continuous Thunderdome by Steve Yegge — a field report written from twelve months in the future, where human code review is gone and something he calls the Land Rush has replaced CI/CD.

Your Evals Are Lying To You by Tejas Kumar — a runnable TypeScript curriculum that starts at a five line assertion and ends at a live diagnostic console.

Article 50 of the EU AI Act, and what it means for you by Craig Abbott — models are already putting invisible watermarks into what they write for you, including the grammar fixes.

Make Claude speak TO you, not LIKE you by Danilo Velasquez — he stopped letting Claude mirror his writing and tuned it to how he takes in information, using retention tests.

Introducing Kitesurf: The agent-first browser that runs in V8 isolates on Cloudflare Workers by Celso Martinho — Cloudflare built a browser on the premise that an agent has no use for pixels.

Web platform and CSS

Dark mode toggles: two states are enough by Lea Verou — the model underneath needs three states, so why does she argue the toggle only needs two?

Dynamic Colour Schemes With Modern CSS by Stuart Robson — color-mix() and contrast-color() doing the job a preprocessor used to do.

Architecture

HTML over WebSockets: real-time SPAs with barely any JavaScript by Andros Fenollosa — two codebases forced to agree through a contract is the accepted way to build a SPA.

Making Navigations Instant in v0 by Jude Gao — they pointed an agent at v0's slow routes in a loop and had it write the failing tests itself.

Something else entirely

They're Made out of Meat by Terry Bisson — a short story from 1991 about two aliens working out what we are made of. Cute short read.

Build: An Unorthodox Guide to Making Things Worth Making by Tony Fadell

Tony Fadell ran the iPod division at Apple as SVP, co-created the iPhone across its first three generations, then left to found Nest and build the Learning Thermostat that Google bought for $3.2 billion.

It's the advice he wishes someone had handed him, starting at building a career and ending at building a company.
