About me·

Howdy! I’m Guangheng Xiao — but around here people call me Mr.OC. I’m a student majoring in Computer Science and Technology at Wuhan University of Science and Technology.

I’m the kind of person who:

• 🧩 Loves turning messy, tangled problems into clean, working code
• 🐛 Thinks a stack trace is just the computer’s way of starting a conversation
• ☕ Fuels up on coffee, then wonders why I can’t sleep at 2 AM
• 📚 Treats every bug I fix as a tiny piece of tuition — and I’ve paid a LOT of tuition

This blog started because I kept forgetting things. My memory is terrible, my notebook is full, and my git log reads like a tragedy. So instead of losing all those hard-won lessons, I decided to write them down — for future me, and maybe for you too.

About this blog

A little digital garden where I grow and store:

• 📝 Study notes — things I learned in class and actually understood (a rare event)
• 🐛 Bugs & error reports — the mistakes I made so you don’t have to
• 💭 Random thoughts — half-baked ideas and musings from my learning journey

Think of it as a public notebook with better handwriting (well, better than mine anyway). If anything here saves you an hour of debugging, consider it a gift from past-me to present-you. 🎁
