About

A learning blog organized around one belief: why beats how.

Most explanations of technical ideas jump straight into mechanism — the API, the formula, the architecture diagram. You learn the how and forget it a week later, because you never built the hook to hang it on.

Posts here lead with the problem. What was painful or impossible before this idea existed? What forces made it inevitable? Once that's clear, the mechanism is mostly obvious — or at least memorable.

Structure of a post

1. Why it exists — the original problem.
2. Why it matters now — where it shows up today.
3. The short answer — a one-paragraph definition.
4. How it works — mechanism, intuition, sometimes code.
5. Famous related terms — pointers to neighbors.
6. Going deeper — primary sources.

Topics span computer science, AI/ML, networking, systems, math, security, and science. Browse by domain or skim the recent posts.
