This is **Yufeng Hub** — my personal knowledge garden. Papers I read, things I
learn, systems I build: they all live here. Two entrances:
- **Notes** (the body of this site) — organized by kind (note / paper /
project / reference), domain (ML / robotics / math / programming / infra)
and tags, with ⌘K full-text search. Several long-form notes carry
**interactive demos**: the animations are computed live in your browser,
not pre-rendered GIFs.
- **The private half** — the vault and the paper wall are rendered only on my
own machine; the public build simply doesn't contain them.
## Public and private
The garden is four repositories: the shell (site code, public), the wiki (note
content, public), the vault (private notes) and papers (poster digests) — the
last two are private repositories. The public site is built on GitHub Pages and
the build never sees them: privacy comes from the build inputs, not from access
control.
## How it grows
- Drafts land in an inbox first, then get filed into their domain and kind.
- Paper posters keep flowing from the papers pipeline; the paper wall follows
automatically on the private site.
- Each note's status (seedling / growing / evergreen) marks how far it has
grown: notes are not articles frozen at publication but plants that keep
being pruned and growing — which is where the "garden" name comes from.
