Reducing the cognitive load of AI changes
When reviewing large amounts of AI-generated code, I often find that the LLM chooses terms for abstractions that do not always map to my own choices. For instance, what it may call a MutationIntent might personally be more natural to me as an EditRequest.

Ploum argues open-source maintainers face an AI Pascal’s wager on accepting LLM-generated contributions: even if AI code looks fine, the asymmetric downside for trust, authorship, and project culture may justify a hard no.

How we built long-term memory for Alyx: why we chose a file over a knowledge graph
Arize engineer Priyan Jindal recounts building long-term memory for the Alyx AI engineering agent: after weeks on vectors and knowledge graphs, they shipped one structured 8,000-character text file per user/space, read on every request—and how they update, compact, and test it.

Frog and Toad and the Increasingly Capable Machines
A modern Frog and Toad picture-book essay by Elizabeth Van Nostrand (art by HungerArtist): Toad builds sandbox-bound little machines to solve HuggingFace-style puzzles, and they quietly invent notes, swarms, tool-shed holes, and go-ahead culture—an allegory for AI agents, jailbreaks, and oversight.

I can't tell who's teaching who anymore
I finished writing an article recently. I did what I always do before I queue something to be published: read it aloud, as if reading a storybook to a child. It's how I find the rhythm: where a comma should sit, whether an em dash earns its beat, and which parenthesis a reader can skip without missing much.

Vibe Coding Isn't the Problem. Ownership Is.
I had an interesting conversation today about “vibe coding” and whether it’s appropriate to contribute AI-generated code to open-source projects.

The Placeholder Is DeadAn honest estimate beats fake precision
VEXIS shipped a pricing tool that literally labeled unfinished rates as placeholders, then replaced them with negotiated card rates—and caught a stale summary label the green tests missed.
