What it does

The System Design Newsletter is Neo Kim's English-language publication about system design and engineering. Its current archive includes networking, architecture and AI-engineering subjects.

A networking edition is a concrete entry into understanding how systems communicate. Use the cited technical material when you need to move from a conceptual diagram to a real design choice. The site offers an AI-engineering playbook with newsletter signup and a separate upgrade for premium editions.
