1

How a CDN serves a page

“How a CDN serves a web page: the browser requests the page from the nearest edge server. On a cache hit, the edge returns its stored copy in milliseconds. On a cache miss, the edge fetches the page from the origin server, stores a copy, and returns it.”

Napkin AI
Napkin AI's result for: How a CDN serves a page
A clear flowchart with icons. The edge server and the origin are steps, not places.

How a pull request gets merged

“How a pull request gets merged: a developer opens a pull request, CI runs the tests, and a reviewer either approves it or requests changes. Requested changes send it back to the developer. Once tests pass and it is approved, it merges into main and deploys.”

Napkin AI
Napkin AI's result for: How a pull request gets merged
Correct and colourful, with a sentence in every box. The loop’s label breaks across lines.

One line: tests and review side by side, both required before merge.

How RAG answers a question

“How RAG answers a question: the user's question is turned into an embedding, the vector database returns the most similar document chunks, and those chunks are added to the prompt so the LLM writes an answer grounded in them, with citations.”

Napkin AI
Napkin AI's result for: How RAG answers a question
Three steps as arrows. The question, the database and the LLM never appear.
