What this blog is for

约 1 分钟

Hi, I’m Duang.

This site is a public notebook: what I’m building, learning, and still thinking through. I don’t chase daily updates. I want notes I can reread later.

Main threads

Agent project breakdowns

Agent / AI apps move fast. I tear down concrete projects: how the loop is wired, which decisions matter, where people trip, and what I learned when I reproduced or changed them.

Full-stack notes

Frontend, backend, APIs, shipping, debugging — notes about how I actually do the work, not empty checklists.

Ideas

Product ideas, technical sketches, half-built things. Writing them down forces clarity, and makes it easier to pick them up later.

Latest digest

Short, one-thing posts: a new tool, a long piece worth following, or something that showed up in production. Start at Latest Digest.

Daily scraps

Occasionally something off the engineering track: mood, observation, a quick aside.


If you’re reading this in English, you’re on the EN side of the same notebook. Chinese originals live on the default site.

  1. Year one of Personal AI: Muse, Today AI, Manus/Cue, and OpenAI DotsIn September 2026 Personal AI settled into four bets. Muse bets on models and distribution, Today AI on state, Manus/Cue on identity, Dots on always-on agents and governance. All four live on a machine that stays running.
  2. Text reveal: complete runnable codeSplit a line into independent elements, then give each one an increasing delay. Every variant builds on that. Zero dependencies.
  3. Magnetic buttons and cursor follow: one formula, four outputsMultiply the distance between the pointer and an element's center by a strength factor, then ease it with lerp. The same formula drives magnets, layered parallax, CSS spotlights, and 3D tilt.
