Google Earth allows users to explore the imagery of the real world. Imagery for Google Earth is taken from satellites, cars equipped with cameras, and other sources. Google Earth renders a data intensive 3-D model of the world on a client application such as a desktop browser or virtual reality system. 

WebAssembly is a runtime for executing code other than JavaScript in a browser-based environment. WebAssembly is useful for data-intensive workloads, and developers can use programming languages such as Rust or C++ in the browser by compiling to WebAssembly.

Jordon Mears works on Google Earth, and he joins the show to talk about the engineering behind Google Earth and how WebAssembly is being used to improve efficiency. He also discusses the state of tooling around WebAssembly today.
