Self-taught developer / Systems notes

A quiet place for
life, systems,
and long learning.

I am Huynh Nhan Quoc, a self-taught developer from Tam Ky, Vietnam. I have been learning through real products, broken deployments, private systems, and years of starting again. This site keeps that road in one place: the ideas, the work, and the life around them.

01 / What is it? Concepts Runtime, bytecode, VM, JIT, compiler, tenant, and the words behind the code. 02 / Why did I learn it? Articles Long essays, field notes, failures, and lessons gathered over time. 03 / How did I build it? Projects Working experiments where ideas have to survive contact with real use. 04 / Who is behind it? About A shorter introduction, the journey, beliefs, and ways to reach me.

Writing / 2026-08-01 Every Building Journey Deserves Respect Source / 9e21988 feat(hydrate): $app is a curated capability surface; coerce range models to number $app becomes a component handle instead of a kernel special-case. It was hardcoded to = window.kit in three scope proxies, so a markup expression (increasingly agent- authored) could reach the entire runtime — $app.destroy(), $app.internal.pageScope, $app.module(...). Now: - $app is a curated, DEFAULT-DENY view of the runtime: appGrants lists the ~38 real capabilities (from the web/native modules + what tenants use); everything else — the runtime's own control API (render/component/module/internal/destroy/run/scope/ has) — is undefined through $app. Capabilities bind to kit (this = kit preserved). - Registered via the SAME alias mechanism as $sidebar/$theme (aliases["$app"]), not a special-case; the three hardcodes are gone. The kernel auto-provides $app globally, so no page boilerplate. - data-kit-alias: a clean attribute to alias any component (data-kit-component="app" data-kit-alias="$app"), alongside the existing name=$alias syntax. An audit confirmed no tenant uses $app as a whole object, so curating breaks nothing. This makes a curated $app the concrete first instance of "a controlled capability surface for generated code" — the toolset agents will author UIs against. Also: data-kit-model on a type=range (like type=number) now coerces to a float, so n + step adds instead of string-concatenating ("0" + "3" = "03"). Caught by the showcase demo. Fixed both ends (kernel modelValue + server modelScope), with the shim taught input.type for the test. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> 2026-08-06

Runtime

The place where code receives memory, values, limits, and a world in which to run.

Bytecode

The compact instruction layer between source language and machine behavior.

Virtual machine

A machine made of software that reads those instructions and enforces their boundaries.

The road so far

Not a straight line.

2015

Blogger and HTML. The first small changes that made the hidden structure of a website visible.

2018

A friend's coffee shop and a Firebase night. Dependency stopped being an abstract technical word.

2020

Home, delivery work, and Kitstack. Real projects began shaping a private Go platform.

Now

Opening the useful parts. Kitwork, concepts, articles, and source code turn private lessons into public material.
