🧠 Second Brain — Digital Garden

A living digital garden built from an Obsidian vault — publicly hosted at garden.christianjeremia.com.

This repo contains the raw Markdown notes. They’re compiled into a static site by Quartz v5 and served through Cloudflare + Caddy + nginx.

✨ What’s Inside

Folder	Purpose
Notes/	Quick thoughts, ideas, random knowledge
Research/	Deep dives, articles, findings
Projects/	Active project notes & planning

(Other folders like Daily/, Templates/, and Archive/ exist locally but are excluded from the public site.)

🔄 Publishing Workflow

# 1. Write/edit a note in Notes/
# 2. Run the publisher (handles everything):
./publish-garden.sh Notes/my-note.md
 
# The script:
# ✅ Scans for privacy leaks
# ✅ git commit + push
# ✅ npx quartz build
# ✅ Reloads nginx

A pre-commit hook automatically scans all staged markdown files for sensitive data (IPs, phone numbers, private paths) before allowing a commit — nothing private makes it to the public repo.

🌐 Domain

The garden is live at garden.christianjeremia.com:

• Domain registered via Cloudflare Registrar (at-cost)
• Cloudflare proxy (orange cloud) for SSL + CDN
• SSL mode: Flexible (Cloudflare handles HTTPS, forwards HTTP to the VPS)
• Automatic redirects: https://garden.christianjeremia.com/ → /notes/index
