    Katie's 10+ year career as a software engineer has been pretty darn fun. She helped develop Google Docs and later was on-call for some of Google's biggest cloud infrastructure as a Site Reliability Engineer. She solved some serious technical and operational challenges at Campaign Monitor as lead of the engineering productivity team, and she helped get education startup Grok Learning off the ground as their first employee. Today you'll find her freelancing for startups, as well as working on her own projects. Fluent in several programming languages, she's at home in both the web browser and deep in the cloud. She's been teaching programming to beginners for a long time, and is now an instructor at General Assembly.


Turns out the browser can run more than just JavaScript! Using WebAssembly we can compile and run other languages too. It gets even more fun when you're trying to mix the asynchronous world of a JavaScript UI with synchronous blocking operations like reading from stdin in Python. Join me to learn what WebAssembly can do and how to use browser features like postMessage, Web Workers, and SharedArrayBuffer to smoothly interact with Python in a terminal in the browser.
