A systems study guide for AI infrastructure — tool design, identity delegation, concurrency, scale, evaluation · by Yiqiao Yin · y-yin.io
Nine sections · systems-first
Copy the whole guide as Markdown — paste it into your notes, a wiki, or an AI coding agent as reference context while you build.
Copies whichever tab you're on — Study Guide or Drill Set.
How to use this. Each drill is a question, the key points behind a good answer, a plain-language analogy,
and a compact model answer. Read the question, answer it out loud from memory, then read on. The analogies exist so the
mechanism survives when the vocabulary doesn't.
