Networking and the Internet, from First Principles
Points and comments are a snapshot, not live.
Internet protocols are patches for specific real-world problems, not a finished blueprint.
A first-principles explanation of networking, starting with the telegraph and circuit switching. It covers how packet switching emerged from bursty computer traffic and Cold War survivability demands. Key concepts: bandwidth and latency are independent physical limits; modems translate bits to analog tones; all protocols (IP, TCP, DNS, TLS) are patches for concrete limitations. The internet works with no central director, handing data between competing carriers.
What commenters are saying
Mixed reactions: some dismiss the "first principles" framing as a cliché or sign of mediocrity, others appreciate the clear explanations. The author (faza) responds to criticism, clarifying they used Claude only for review and visuals, not for generating text. Several commenters praise the bandwidth vs. latency treatment and historical context. Design complaints about tiny dark-gray text on black background. A few accuse the article of being AI-generated, citing the author's superhuman productivity.
