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!

AWS has elevated Rust support in Lambda from experimental to generally available, empowering developers to create high-performance, memory-safe serverless applications. This milestone enhances developer confidence, backed by AWS support and SLA. While it offers speed comparable to C++, challenges such as lengthy SDK compile times and increased binary sizes remain key considerations.

Sustainable APIs benefit most from minimalism, Jochen Joswig said at OOP Conference . Deployment should consider energy, usage, carbon intensity, hardware acquisition. Remote work, long device lifespans, and green office practices can lower emissions. Efficient CI, selective builds, smaller artefacts, and optimized assets can further reduce energy use.

Martha Lambert introduces the "Observability Lasagna" - a four-layer framework (Overview, System, Logs, Traces) focused on connecting layers for an optimized debugging UX. Learn practical tips for instrumentation, visualizing limits, and using event logs/exemplars to shift from general metrics to user-impact focused triaging. Essential for engineering leaders aiming for system reliability.
