The Ground is Shaking: Why Designers Must Flip the Script on AI

Senior designers must stop deferring to AI as the expert, reclaim the role of the More Knowledgeable Other, and actively define the constraints and problem theory that AI works within.

Design + Development

Pretext

Cheng Lou's Pretext is a browser library that calculates line-wrapped text height without touching the DOM. Simon Willison walks through how it works: prepare() segments and measures text on an off-screen canvas, then layout() emulates word-wrapping to return fast height estimates.

Retune

lets you select and tweak any element right in the browser. Your AI agent writes the code. No more prompting for pixels.

Huegrid

Gradient tool with 22+ modes, noise, dither, aurora, mesh, liquid chrome. Export as high-res images or framework-ready code for React, Vue, and Svelte. Community gallery lets you share and remix others' work.

The Claude Code Source Leak: What the Exposed Code Reveals

Anthropic's Claude Code leaked, and Alex Kim dug through the code: anti-distillation guards, undocumented agent features, and buried security checks.

Emdash

is a full-stack TypeScript CMS that takes the ideas that made WordPress dominant and rebuilds them on serverless, type-safe foundations.

Meet the New Cursor

Cursor 3 turns the IDE into a coordination layer, multi-repo layouts, parallel local and cloud agents, and built-in demo verification, without gutting the editor experience.

Work + Mindset

Don't Let AI Write for You

Every time you hand writing to an LLM, you skip the thinking. The output isn't the point , working through it is.

I Quit: the Clankers Won

David Bushell says it's more important than ever for humans to keep blogging and sharing original thoughts on an open, independent web

Bad Analogies

Packy McCormick on why WeWork and Uber were never the next Amazon , and why that same bad analogy is now being recycled for AI labs burning through capital.
