Writing about curiosity, insights, and reflection.

About Jin Wu

• AI-first builder, writer, and ex-Google engineer now crafting products at startup speed.
• Documenting the journey in both English and Chinese, from vibe coding experiments to founder life.
• Exploring how humans and AI collaborate, sharing what works (and what does not) in practice.

Site Quickstart

• Run bundle exec jekyll serve to preview locally.
• Posts live in _posts/, layouts in _layouts/, assets in assets/, and configuration in _config.yml.

Terminology

• Home page: http://127.0.0.1:4000/ (layout home).
• Post page: http://127.0.0.1:4000/YYYY/MM/DD/slug.html (layout post).

UI Conventions

• Social icons (L/X) show only on the Home header.
• Post pages have a scroll‑aware Catalog FAB that appears after the hero header and aligns with the content column.
• _site/ is generated and not tracked.

Local Dev Environment

• Ruby: 2.6.x works; modern Ruby via rbenv recommended.
• RubyGems: 3.2.3+ recommended to silence Bundler warning.
• Bundler: ~> 2.4 with Ruby 2.6.

Upgrade commands (system Ruby):

sudo gem update --system 3.2.3
sudo gem install bundler -v '~> 2.4' --no-document
bundle install

Optional (recommended) with rbenv:

brew install rbenv ruby-build
rbenv install 3.2.2 && rbenv local 3.2.2
gem update --system && gem install bundler jekyll --no-document
bundle install

Agent Notes

• Prefer rg for code or text searches; stay concise when responding.
• Keep the home header clean—surface socials via the icons, not text blocks.
• Share any notable insights or issues you encounter while working in the repo.
