About

Hi, I’m pengc. Welcome to pengc’s log.

This is a growing collection of personal learning notes, documenting both questions and the process of understanding them.

Each note aims to leave something useful: a clear question, an explanation in my own words, a testable example, and references worth exploring.

The format of this site is inspired by Lil’Log. These notes will grow with learning and practice, and evolve as my understanding changes.
