🌱 Tony’s Knowledge Garden

Welcome. I’m Tony — Chinese teacher, AI builder, and obsessive note-taker.

This is my public knowledge garden: a living collection of ideas from 6000+ hours of teaching, reading, and building. Not a blog — more like thinking out loud, made permanent.

What’s here

• AI & Technology — Notes on LLMs, agents, Claude Code, and the AI builder ecosystem
• Computer Science — Course notes from Andrew Ng, Stanford CS336, and others
• Mathematics & Education — How people actually learn math, and what AI changes
• Thinkers — Karpathy, Sutskever, Dan Koe, Cathie Wood and others worth following
• Business — Startup thinking, creator economy, building in public
• Academic — University-level math and CS notes
• Teaching Quotes — Insights from real Chinese teaching sessions
• Open Source Projects — 15 projects on GitHub @shengdabai
