Overview

This is a Zettelkasten-style knowledge management system and technical blog.

Notes are written in org-mode and managed with org-roam, enabling bidirectional linking between notes.

The content is then published to multiple platforms through various exporters:

• Main blog via ox-hugo + Hugo
• Zenn.dev via ox-zenn
• dev.to via ox-gfm
• PDF slides/articles via ox-typst + Typst

All builds are reproducible using Nix flakes.
