The world after Scala 3.9 LTS

In this talk, I will introduce the highlights of what to look forward to in Scala 3.9 LTS, as well as how to think about the upcoming new release.

Migration Without Tears: 2,000 Projects, One New LTS

In this talk, I will present insights from running the Open Community Build, where we continuously build and migrate nearly 2,000 open-source projects to the newest Scala Next versions, from scratch, every week.

Coffee Break

Cyfra: Scala on GPU

Learn how to accelerate Scala code by orders of magnitude with Cyfra.

Scala and C – tight as brothers

Scala Native can interact with C code and libraries, greatly expanding the library ecosystem beyond pure Scala offerings. Let's see the low level and high level tools that make it possible, talk through challenges of encoding various C concepts in Scala, and demonstrate what popular C libraries look like when used alongside idiomatic Scala code.

Protobuf Goes Scala-First

Protobuf is commonly associated with code generation. However, in large projects with tens of thousands of message definitions, this approach can lead to an overwhelming amount of generated code. In this talk, I’ll share my journey in search of a different approach to this problem.

Lunch Break

The Concurrency Triangle: Scala Fibers, Java Virtual Threads, and Kotlin Coroutines

Scala Fibers, Java Virtual Threads, and Kotlin Coroutines - this talk shows how this elegant solution manifests at three different abstraction levels.

Beyond `flatMap`: Is Kyo the Future of Scala Effects?

For nearly a decade, Scala's concurrency has been driven by Akka, Cats Effect and ZIO, each with its own vision for purity, safety, and pragmatism. Kyo enters this incredible ecosystem with a fresh perspective.This talk provides a critical, technical comparison of these systems through a unified framework.

Controlled Concurrency Testing for Scala

This talk presents McCCT, a new concurrency testing tool developed at KTH by the speakers in the context of an ongoing research project.

Coffee Break

Real-Life Scala Capture Checking

This will be a live coding demonstration of Scala's newest feature set: capture checking.

Effects as Capabilities

When writing software, we currently seem to have to choose between an imperative style - easy to read and write, hard to reason about - and a monadic style - hard to read and write, easy to reason about.This talk is about being greedy and getting the best of both worlds, because we deserve it.

Type-Classes (in Scala 3)

We'll explore type classes in Scala 3, using its new rules for givens, extension methods, and mechanisms for automatic derivation via mirrors or macros.
