Pixels to Packages

In this episode of Pixels to Packages , we dive deeper into one of the coolest systems ever built: internet routing. Every click, stream, message, and AI prompt depends on millions of packets finding secret routes across cities, countries, oceans, and data centers in real time, without any central map controlling it all. We unpack how the internet constantly adapts around failures, congestion, and...

In this episode of Pixels to Packages , we explore one of the most important and least visible systems behind modern life: routing. From internet traffic moving across global networks to physical packages traveling through warehouses, trucks, aircraft, and delivery hubs, the same fundamental challenge appears again and again. How do you move enormous numbers of things through constantly changing s...

In Episode 5, we move from pixels and intelligence into the moment money changes hands, following the full flow from landing on a storefront through everything that happens after you decide to buy. With my friend, Shopify’s Head of Engineering, Farhan Thawar, we trace the path from storefront to cart to checkout, unpacking how APIs, payments, fraud systems, and global infrastructure turn a simple...

In Episode 4, a very San Francisco moment, riding in a driverless Waymo while using AI on a laptop connected to the internet, becomes a window into how the modern web is evolving. The same systems that once delivered simple web pages are now routing requests to powerful AI models that return complete answers, code, and ideas. What once moved pixels across the internet is beginning to move intellig...

There is no such thing as just one server. In Episode 3, we move beyond the browser and into the distributed systems that actually power the web, including load balancers, server fleets, data center networks, and CDNs that span the globe. Every tap is routed, replicated, inspected, and protected before it ever becomes pixels, and this is only the beginning of the journey toward the physical world...

In Episode 2, we pick up where the packets left off and zoom inside the browser to see how raw data turns into pixels. We break down HTML, CSS, and JavaScript, peek inside the JavaScript engine and its sandbox, and finally reveal the browser’s secret obsession with boxes. By the end, you will never look at a web page, or a buy button, the same way again.

In this very first episode, we begin the journey from pixels to packages by following what happens the instant you open a browser or app and try to reach something on the internet. We trace how names become destinations through DNS, how data is broken into packets, and how layered protocols move those packets across the network to distant servers and back. By understanding these invisible first st...
