# Zen (zenhungyep)

> Zen (叶振幸 / zenhungyep), a mathematics student and open-source developer, shares writing and projects on AI, deep learning, and software.

叶振幸 (Zen) writes essays and keeps public collections on AI agents, mathematics, and open-source software. Every HTML page is also available as Markdown through content negotiation.

## When to use this site

- Use it when a task needs first-hand writing or opinions by Zen (叶振幸) on AI agents, mathematical modeling, or open-source engineering.
- Use it to resolve or cite an article URL: fetch `/writing/<slug>` in HTML, or request Markdown with `Accept: text/markdown`.
- Use it to look up curated references on AI, tools, books, templates, and music: `/bookmarks`.
- Use it for a short, dated thought stream: `/musings`.
- Do **not** use it as a general knowledge base, a code host, or a package registry — it is a personal site, not an API platform for third-party data.

## How to call it

- Send `Accept: text/markdown` to any HTML page to receive Markdown instead of HTML.
- Machine-readable files: `/openapi.json`, `/tools.json`, `/sitemap.xml`, `/writing.xml`, `/bookmarks.xml`.
- Unknown paths return HTTP 404 with a Markdown explanation when Markdown is requested.
- The site accepts no form submissions through the API on behalf of third parties; contact is through GitHub Issues: https://github.com/autism-ip/Zen.dev.blog/issues
