Scalar 2026, the 11th edition of Central Europe's premier Scala and functional programming conference, took place in Warsaw over two days. Highlights included a keynote by Scala creator Martin Odersky on building trust in AI agents using types and capabilities, a Scala 3.9 LTS roadmap, GPU computing with Cyfra, concurrency comparisons between Fibers, Virtual Threads, and Coroutines, and debates on effect systems like ZIO, Cats Effect, and Kyo. Day two covered Scala 3 features like Opaque Types and Macros, the Scala AI landscape, LLM integration strategies, and using Scala as a scripting replacement for Bash and Python. The event was organized by SoftwareMill and sponsored by JetBrains, Aikido Security, and VirtusLab.
