Hello. This is my digital garden. It is a place where I learn in public.
I take notes as I study new subjects. Each note explains one idea. Notes link to each other, so you can follow an idea from one place to the next.
What you will find here
- Concepts. Short notes that explain one idea each.
- Threads. Logs of what I learned in one session, and what I still do not understand.
- Topics. Hubs that group the notes about one subject, for example Databases.
Start here
I am now learning how PostgreSQL locks work. Read Row Lock Modes first. Then read Wait Policies and Table Lock Modes. The log of my first session is in 2026-10-05 Databases - Postgres Locking.
How to read this site
Start with a topic hub. Follow the links inside the notes. Use the search box to find a word. Use the graph view to see how the notes connect.
About the notes
These notes are not finished. I change them when I learn more. If a note is wrong, the note is wrong because I was wrong when I wrote it.
