From $20/Seat to $2,000/Engineer: The Real Price of AI Coding
AI will replace workers, I am sure you already heard this somewhere. In the end of 2025 many people lost their jobs, Big tech fire a lot of roles and replace it with AI. The hype took over Silicon Valley. The math seemed seductively simple. No need of Junior devs, middle devs cost about 150K…
How the Internet Knows Where You Live IP Addresses, Autonomous Systems, and Route Aggregation.
So far in this series, we’ve built a local network. Machines can talk to each other inside your home. The switch knows where everyone is. Ethernet frames find their destination.

How…
Why Fiber Optics Took Over the Internet (And What’s Actually at the Bottom of the Ocean)
In the previous article, we built up a picture of how data travels through a copper cable voltage levels, encoding tricks, error correction. It works. It works well, actually. But copper has a hard limit. The further your signal travels, the more it weakens. Electrical resistance eats away at the signal. Interference from nearby cables,…
How Does Data Travel Through a Cable? The Physics Behind Every Click You Make
Every time you click a link, your browser doesn’t magically receive a webpage from a server across the world. Something physical has to happen. Electrical signals have to move. Decisions have to be made. And an extraordinary set of engineering tricks developed over decades has to work perfectly, every single time. This article tears open…
