## What's on this site
The blog reflects on how the world works, with a focus on first-principles thinking, learning loops,
software engineering craft, and decision-making. Posts are essays, not tutorials — each one tries

noticing confusion, the human log, dealing with information overload.
- Software engineering: how Unix works, how Git works under the hood, lessons learned from senior
software engineers, debugging, code review, testing, distributed systems.
- Learning and personal growth: how to learn anything quickly, hacking life like a video game,
long-term thinking, year-in-review essays, reading lists.
- Psychology: psychology of human misjudgment, cached thoughts, Sapiens summary, computational
kindness, personality.

coordination problems.
