Pulled the N+1 out of the dashboard post list: 140ms → 18ms

Shipped a small but satisfying refactor today: pulled the N+1 out of the dashboard post list by eager-loading category + tags in a single query. Page went from 140ms to 18ms. The boring wins are the best wins.

Hot take: most design systems are just component libraries with a marketing page

Hot take: most "design systems" are just component libraries with a marketing page. The actual system is the decisions — spacing scale, type ramp, motion language — not the button variants. (Yes, I will die on this hill.)

Rust async stream processing: walking a 4 GB event log without blocking the runtime

We ingest a rolling 4 GB event log across hundreds of thousands of lines, and the first cut blocked a worker on every 8 MB page fetch. Here is the async stream version that keeps the runtime hot end to end — patch, review comments and all.

Zero-runtime deep immutable patch utility in TypeScript 5.4

Zero-runtime deep immutable patch utility in TypeScript 5.4. Preserves discriminated unions without pulling in Immer or Lodash — 12 lines, no dependencies.

immutable-patch.ts

type DeepPatch<T> = {
  [K in keyof T]?: T[K] extends object ? DeepPatch<T[K]> : T[K];
};

export const immutablePatch = <T extends object>(base: T, patch: DeepPatch<T>): T => ({
  ...base,
  ...Object.fromEntries(
    Object.entries(patch).map(([k, v]) =>
      [k, typeof v === 'object' && v !== null ? immutablePatch(base[k], v as any) : v]
    )
  ),
});

Tailwind v4 dark mode classes stopped working — the `@custom-variant` fix

SOLVED: if you are on Tailwind v4 and your dark mode classes stopped working, check that you moved from darkMode: 'class' to the new @custom-variant dark syntax. Spent an hour on this so you do not have to.

MK Matthias Klein accepted

@custom-variant dark (&:where(.dark, .dark *)); in your main CSS is the v4 replacement — the old darkMode: "class" option silently no-ops.

Best practice for chunking a 500k-row export? lazy() seems to hold the connection hostage in worker queues — anyone benchmarked chunkById vs lazyById on a busy primary?

The tools I trust are the boring ones — what quietly carries your workflow?

The tools I trust are the boring ones: ripgrep, fd, make, jq. Every shiny dashboard eventually becomes a shell alias. What "boring" tool quietly carries your whole workflow?
