SBTB 2019: Salar Rahmanian & John A. De Goes, Next-Level Diagnostics.... with ZIO

ai.bythebay.io Nov 2025, Oakland, full-stack AI conference Title: Next-Level Diagnostics for Async & Concurrent Errors with ZIO A strength of the Scala programming language is its powerful support for asynchronous and concurrent programming—historically with Future and Akka, and today, with next-generation effect systems like ZIO. While ZIO features like fiber-based concurrency, software transactional memory, and async/concurrent resource safety may grab headlines, in everyday programming, we spend a lot of our time debugging our async/concurrent code. In this presentation by John A. De Goes and Salar Rahmanian, you’ll see how newly-developed features in ZIO make it easier than ever to troubleshoot problems in modern applications. You’ll discover how execution traces show exactly the line-by-line flow of your async/concurrent code (including where it would continue to if it did not error!), and how interactive debugging features let you identify and troubleshoot stalled async code. Discover just how powerful async and concurrent programming has become in Scala!
