About

Jaden.log is a developer blog about concepts I studied and problems I ran into at work. Its motto is “Write down what I learn, and learn again by writing”.

Topics

AI — Notes from using and building with AI tools like Claude Code and Codex, and thoughts on learning with AI
Infra — Problems from Kubernetes resource settings and on-premise installs, traced back to the cause
Go — What slices, interfaces, and context really hold, plus timeouts and optimizations met in production
Database — Transactions, locks, and normalization as concepts, then indexes and multi-pod concurrency in practice
CS — CS fundamentals revisited along the path of a single request, checked against how Go and Kubernetes actually behave

How posts are written

Command output and numbers in a post come from runs I did myself, with the OS and versions noted. Output I could not run is labeled as expected output.
When a conclusion changes after publishing, the change is recorded with its date at the end of the post.
Every post has a Korean and an English edition.
The source of this blog, posts included, is public on GitHub.
