Hi there! I’m Lesley Lai, and this is my little corner of the web where I share my notes that I accumulated since 2023, mostly focused on math and programming. I also post a few informal articles sharing my personal opinions here.

Most of the notes and articles here are incomplete and unpolished, reflecting my limited understanding. I also usually don’t proofread them, and if you come across any errors, feel free to leave a comment on that page.

If you are interested in the features and styles of this site, I keep a customization log for this site.

How to Navigate This Site?

I primarily follow a note-taking method inspired by the Zettelkasten system, and as a result the site uses a mostly flat folder structure. To navigate this site, you’ll mainly rely on links and backlinks. However, I do try to incorporate some hierarchy back by using a parent: property in Obsidian and create map of concepts pages to organize related ideas.

Not sure where to start? Check the note index or my writings.
