Agenda: 18:00 Doors open 18:20 welcome, doors closing.. 18:30 From Reactive Streams, through Virtual Threads, to Flows - Adam Warski 19:30 break 20:00 Armeria: The Microservices Framework You Haven't Tried Yet - Dominik Dorn 21:00 networking **From Reactive Streams, through Virtual Threads, to Flows** Since Java's inception, the programming model has shifted from synchronous to asynchronous, and for good reasons: improved performance, higher throughput, and lower latency. Reactive Streams greatly simplified the development of reactive systems by incorporating elements of functional programming. However, with the introduction of Virtual Threads in Java 21, Java shifts back towards a purely synchronous model, while retaining high performance. Does this render initiatives like Reactive Streams obsolete? Can we combine the benefits of Reactive Streams with the approachability of Virtual Threads, the elasticity of modern Java, and the guarantees of functional programming? And what are the tradeoffs? **About Adam Warski** Adam Warski is the co-founder of SoftwareMill and head of R&D at VirtusLab, where he primarily generates code using Java, Scala, Rust and other interesting technologies. He is actively involved in open-source projects, such as Ox, Jox, Tapir, sttp, and others. He has also been a speaker at major conferences, including JavaOne, Devoxx, GeeCON and ScalaDays. In addition to writing closed- and open-source software, he spends his free time exploring various programming-related subjects. Any ideas or insights he gains usually end up on his blog ([https://warski.org/articles](https://warski.org/articles)). **Armeria: The Microservices Framework You Haven't Tried Yet** "One port to rule them all" .. that's the promise of Armeria, the microservice framework created by the creator of Netty, Trustin Lee. Armeria has built-in support for gRPC and Thrift, automatic endpoint descriptions (OpenAPI) and works with your Spring Boot App, your legacy Tomcat project or your dropwizzard app. We'll take a look at these (and more) features in this talk. **About Dominik Dorn** Dominik Dorn is a senior software engineer in Vienna and has been running the Java Vienna Meetup since \~2009. He has extensive knowledge in the Java and Scala ecosystems. He sometimes "tweets" on [https://x.com/domdorn](https://x.com/domdorn) . You can also find him on [Linkedin](https://www.linkedin.com/in/dominik-dorn/) where he happily accepts new connections from the community. He is doing freelance software consulting, so if your company needs help, he might have some resources left for helping you.

We are pleased to welcome Katrina Brock from Max Planck Society to present an R package for analyzing animal movement data. Join us to explore how R can be put to work in animal behaviour research. **Travel Paths: Bridging the usability gap in open source animal movement algorithms** The behavior ecology literature offers a rich library of approaches for finding patterns in animal movement data. While many of the biologists developing these algorithms publish their code, it is rarely optimized for reuse. Even well-designed packages with similar workflows have different interfaces that potential users need to learn one by one. By wrapping these algorithms in a standardized interface, the “Travel Paths” framework reduces researcher toil. Instead of digging through scripts and learning disparate conventions, they can run many methods with just a few functions. The framework is composed of two packages: the trackframe package provides a flexible and interoperable format for input data while the travelpaths package, taking inspiration from parsnip, offers the interface for movement models. In this talk, we’ll discuss how we designed this framework and how it can be leveraged to enable even novice R users to apply a variety of methods to their animal movement data.

Agenda (preliminary) 18:00 doors open 18:20 welcome 18:30 Talk 1 19:30 break 20:00 Talk 2 21:00 Networking **A Tour of Ox 1.0: Direct-Style Concurrency and Resiliency** Ox provides a toolkit for safe concurrency and resiliency for Scala on the JVM. After two years of prototyping, we’re delighted to showcase the final product. With Ox, you can build and deliver direct-style Scala applications today. In the code-first presentation, we’ll begin with concurrency (including lower-level structured concurrency scopes and higher-level concurrency operators). Next, we’ll proceed to Ox’s approach to error management and type safety in that area. We’ll then explore Ox’s direct-but-reactive streaming library before concluding with its built-in resiliency toolkit. Software is never finished, so we’ll also share what lies ahead for Ox specifically and our plans for direct-style Scala generally. **About Adam Warski** Adam Warski is the co-founder of SoftwareMill and head of R&D at VirtusLab, where he primarily generates code using Java, Scala, Rust and other interesting technologies.

AWS Lambda Durable Functions change that. You write sequential code in a single Lambda function that can suspend for days and resume instantly, and you only pay for active compute time. In this session, we will orchestrate Amazon Bedrock conversational agents using the Sinch Conversation API to handle inbound interactions. You will learn how to dispatch AI specialists, use simple callbacks to wait for asynchronous human input, and replace heavy infrastructure boilerplate with native durable execution. **"How RBI is automating its cloud foundation with AWS Step Functions"** *Speaker:* **[Roman Jokel](https://www.linkedin.com/in/roman-jokel/),** Cloud Architect (Raiffeisen Informatik) **/ [Florian Ettinger](https://www.linkedin.com/in/florian-ettinger/),** Solution Architect (AWS) *About the talk:* How can AWS Step Functions transform daily cloud operations?

## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge. This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow. Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided! Parking: Plenty of free spaces available on-site. ###

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.
