Special Guests: Kurt Mackey

In this episode, the JavaScript Jabber panel talks to Kurt Mackey about Fly.io. At Fly.io, they are "building a JavaScript platform that gives you the power to build your own CDN." They talk about how Fly.io came to fruition, how CDN caching works, and what happens when you deploy a Fly app. They also touch on resizing images with Fly, how you actually build JavaScript platforms using Fly, and more!
