Quinn’s Mind Palace

Hi, I'm Quinn Gao.

This is a tech blog that holds my most recent notes and rants.

Currently living in the Bay Area, I am best known as SuperGrey, a Wikipedian from Chinese Wikipedia.

Starting 2026, I'll try to update this blog more often, as an effort to improve my English writing.

I also have a Chinese blog focused on anime reviews and life updates. I'll update that blog more often as well, as my new year's resolution.
