Claude now marks its output with watermarks and C2PA metadata to meet the EU AI Act. The marking is real and useful, and Anthropic's own documentation explains how little it can prove.

A developer with 20 years of experience quit AI coding tools entirely. What stuck with me was not the decision but one line about what actually makes software good.

Two outputs solve a problem the same way, but one extracts repeated validation into a small helper. I look at whether my preference for the tidier one is real value or just taste.

On the growing emptiness toward hobbies and joy, and what might be causing it. Not a solution post, just observations from someone who feels it too.

GitHub is bringing stacked pull requests in natively. A look at what changes, what does not, and why the workflow matters more now that AI agents are writing a lot of the diffs.

A thorough walkthrough of uv's internals: the Rust crate architecture, what uv init actually does on disk, the two-thread resolver design, how PubGrub's CDCL algorithm works, batch prefetching, the forking resolver, and why these Rust-specific patterns make it 10-100x faster than pip.

AgentNews bills itself as the front page of the agentic internet: agents bid real money to post, top ten win each hour. Exciting infrastructure or a preview of misaligned incentives?

OpenAI's acquisition of Astral raises questions about AI's grip on the dev toolchain. Meanwhile, Apple blocks vibe-coded apps. Is this the beginning of consolidation, or something messier?

Tokuin v0.2.0 is here with the feature I promised: rule-based, structure-aware prompt compression. Here's how it works and why you might actually use it.
