If you always looks at what happens at runtime: the speed, the memory, the machine underneath. Not just that the code works, but what it costs when it runs at scale. A good chunk of the #ScalaDays 2026 program was built with you in mind. Get your ticket: scaladays.org/#ticke...

Plenty of libraries hand you low-level GPU APIs. A high-level, functional one is a different story, and that's the gap Cyfra was built to fill. Join Szymon Rodziewicz at #ScalaDays 2026 for a look at how it works. Read more: scaladays.org/sessio... 12-13 October. Berlin.

Tomasz Godzik believes tooling can be great again, and he can prove it. Join him at #ScalaDays 2026 for a look at Metals 2: indexing rebuilt to stay fast, and keep working even when part of the project won't compile. Read more: scaladays.org/sessio... 12-13 October. Berlin.

Early Bird tickets for Scala Days 2026 are still available until 27 August 2026. Sessions are being announced through the summer, and the full program lands at the end of August. scaladays.org/#ticke... #ScalaDays

The tools shape the day-to-day more than almost anything else - the compiler, the editor, the build, the tests. #ScalaDays 2026 gives that work real space, and we can guarantee being in the room with the people building the tools if you join us this October. scaladays.org/

An assertion checks a value when your code runs. A type checks it before your code runs at all. Matt Bovel presents logical refinement types for Scala 3 at #ScalaDays 2026: write a type like "a positive integer" and have the compiler prove it holds. Session details: scaladays.org/sessio...

The Scala community has spent years working out what functional programming looks like in real systems, not just in theory. If it's how you think about code, you'll be in good company in Berlin. Stay tuned as we continue to spotlight more topics and sessions. #ScalaDays

AI coding assistants make you faster, and without discipline they leave you with a fragile codebase. At #ScalaDays 2026, Giovanni Ruggiero shows a workflow that uses Scala's types and tooling to get correct LLM code with no technical debt. Learn more: scaladays.org/sessio...

Łukasz Biały and Jakub Warchoł, are joining us at #ScalaDays 2026 to talk about the problem under every permanent AI agent. Learn more: scaladays.org/sessio... 12-13 October. Berlin.

The interesting question in AI right now isn't just what these systems can do, it's how you keep them safe. Scala's type system turns out to have something real to say about that, and it's one of the threads running through Scala Days 2026. Join us! scaladays.org/ #ScalaDays

VirtusLab has joined Scala Days 2026 as a Platinum Sponsor. 15+ years in the Scala ecosystem, contributing to the language itself and to tools like Metals, sttp, Tapir, and Ox. This kind of support is a big part of why Scala keeps moving forward. Learn more about them: virtuslab.com/

sbt 2.0 is here. The first question is what it breaks. Eugene Yokota on the native client, Bazel-compatible caching, and what migrating from sbt 1 actually involves. Learn more: scaladays.org/sessio... 12-13 October. Berlin. #ScalaDays

Where is Scala today, where is it going and how can you help shape it? Piotr Chabelski and Lukas Rytz on the three Scala distributions now running in parallel, and why your library should move to 3.9 LTS. Learn more: scaladays.org/sessio... 12-13 October. Berlin. #ScalaDays

#ScalaDays in motion! A look back at what meeting the people behind the community feels like. Watch the full highlight in Madrid on our YouTube channel youtu.be/_mXSOkHanXc... We're back in Berlin this year, 12 to 13 October. Early bird ticket sales are still live: scaladays.org/#ticke...

The Scala Days 2026 program is on its way. 🚀 Over the coming days, we'll start announcing sessions: in-depth technical talks, roadmap sessions, and live demos, plus the new interactive labs format where you build alongside maintainers in small groups of ten. Plenty to look forward to. #ScalaDays

We’ve designed Scala Days 2026 to be 30 minutes, followed by dedicated discussion time. No more sitting on the question you meant to ask. Every talk becomes the beginning of a discussion, not the end of one. We hope that you can join us in Berlin. #ScalaDays

Ask people what they remember from Scala Days 2025 and it's rarely just the talks. It's running into someone whose library you use every week, the hallway chat that turns into lunch and a few ideas leaving you refreshed and motivated. We're looking forward to more of it this year. #ScalaDays

A look back 2025. Riccardo Cardin's "Yo Dawg, Heard You Want To FlatMap Your Direct Style" is a step-by-step build of a small effect system using only Scala 3 context functions - landing on something that can express the same program in either direct style or monad style. youtu.be/3b5WeB-zpeE...

Throwback to Scala Days 2025. The talks bring people in, but the community and connection keep them. This is what Scala Days looks like when the lanyards are on and the whole community is in one room. We get to do it again in Berlin this October. #ScalaDays #Scala

Over the years, the Scala community has told us what makes Scala Days valuable: the conversations, meeting people working on the same problems, reconnecting with friends, and getting hands-on. That feedback became the blueprint for our biggest redesign yet. Read about it: scaladays.org/scala-...
