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!

JobRunr has introduced ClawRunr, an open-source Java AI agent for scheduled, recurring, and one-off background tasks. Formerly JavaClaw, it runs on users' hardware and combines conversational interaction with persistent task execution, MCP tools, browser automation, and web, Telegram, and Discord channels, while using JobRunr for scheduling, retries, and monitoring.

Confluent introduces a new approach in Apache Kafka that moves schema IDs from message payloads to record headers, aiming to simplify schema governance and evolution. The update integrates with Schema Registry, improves compatibility across serialization formats, and reduces coupling between data and metadata in event-driven architectures.

Hilary Mason shares her journey from academia to building AI products at scale. She discusses the shift from discrete engineering to probabilistic mindsets, explaining why managing "human considerations" is the hardest part of the stack. She explains the "existential crisis" for engineers, arguing that great architecture today is about context management, systems thinking, and good taste.

Vitest 4.1, developed by VoidZero, enhances JavaScript testing with features like test tags for filtering and configuring tests, an experimental mode to bypass Vite's module runner, and new lifecycle hooks. It supports Vite 8 from the start. Notably, it reports improvements in performance compared to Jest. The release addresses issues and provides guides for migration.
