Hi! I’m WD, a sophomore computer science student at Hangzhou Dianzi University with a focus on algorithms and competitive programming.
Competitive programming
- Codeforces: WD
- AtCoder: W_D
- Highlights:
Gold medal in 2025CCPC Harbin site, and a few silver medals.
Tools I love
- Emacs as my daily driver; configuration is tuned for fast coding and note-taking.
- Org-roam for building a networked knowledge base—this site is published from those notes.
- Favorite workflows: (e.g., Magit for git, LSP/treesit for coding, org-babel for runnable snippets)
Notable open source projects
- majutsu - Emacs interface for jujutsu inspired by magit
- More on my profile: github.com/0WD0
What you’ll find here
- Fresh contest write-ups, Emacs/org-roam tips, and distilled algorithm notes.
- Occasional deep dives into how I structure knowledge and automate workflows.
