Getting Started with AI in 2026

A practical guide to integrating AI into your workflow without overcomplicating things.

The eval harness is the product

Why I treat LLM evaluation infrastructure as a first-class system, not a notebook — and the four signals every AI pipeline should gate on.

Event sourcing without the cult

A pragmatic take on when double-entry / event-sourced models earn their complexity — and when they don't.

Vue 3 at console scale

State, command UX, and optimistic mutations for operator tools that real people use eight hours a day.

RSC streaming, measured

TTFB numbers from moving a retail storefront to the edge, and the cache-mesh design that made it hold.

Field note: AI-native code review

The review loop I actually run now — agent drafts, I arbitrate. What got faster, what got worse.

Refactoring is a delivery skill

Fifteen years in, the highest-leverage thing I do is make change cheap. A taxonomy of safe refactors.

Node.js worker pools, revisited

When threads beat processes, and a benchmark that surprised me on a CPU-bound parsing job.
