Codetown ::: a software developer's community
Chicago Kotlin User Group x Android Listeners
Hosted at GrubHub, July 17
Coroutines are the new hot stuff, and right now they’re being added to lots of libraries. But what if you don’t want to use an alpha01 in production code? What can coroutines do on their own, right now? In this talk, we’ll discuss the power behind structured concurrency and how we can use it to make our entire stack lifecycle-aware. We’ll look at examples of how to turn any callback or long-running code into a coroutine, and we’ll go over when and how to use Channels to handle hot streams of data without leaking. Finally, and most importantly, we’ll see how we can use these tools to inform our application architecture, so that we can quickly write maintainable and testable features. Thanks to GrubHub for hosting!

Spencer Judge discusses the architectural pattern of building a shared core in Rust with language-specific layers on top. Drawing from his work on Temporal's SDKs, he shares lessons on navigating FFI boundaries, bridging async concepts, and managing memory safely. He explains the limitations of native extensions and how emerging tech like WebAssembly can streamline cross-language architecture.
