The longest day of the year is comming and let's another Kotlin meetup. This time we geather at N26! **⚠️⚠️⚠️ Due to a venue policy please submit the following form for additional details. Without it, you won't be allowed inside the venue:** https://forms.gle/XjqVXkD3FARCM6jA8 **Line-Up:** 👉 **TestBalloon: Kotlin testing is easier (and more fun) than you think** *by Oliver Okrongli* You want an easier way to write tests? Parameterize tests in plain Kotlin? Reuse a series of tests? Easily extend own your test setup? Have first-class support on all platforms? All without struggling with a huge framework API? TestBalloon is a new test framework that brings the power of Kotlin to your test setup. With a small-surface API, a hierarchical test structure and an extensible DSL, TestBalloon makes Kotlin testing easy, even at scale. Oliver, the author of TestBalloon, will show testing patterns and strategies and lots of practical examples, ranging from simple unit tests with less boilerplate to advanced testing with coroutines and generated data. This talk is based on insights first presented at KotlinConf 2026 in Munich. At the end of this talk, you’ll be able to firmly the answer the question: "How can I master Kotlin testing with ease, and make my team release with joy and confidence, every time?" 👉 **One Topic to Rule 'Em All** *by Yonatan Karp-Rudin* Kafka delivered every event exactly once, in order, and lost nothing. So what broke? This talk follows that question into the gap most event-driven systems leave open: what actually guarantees the order your domain depends on, and what quietly doesn't. We start from a real log line, find the crack in an architecture that looks clean and ships fast, and rule out the fix everyone reaches for first. The cure turns out to be one sentence of domain thinking plus one line of config, though the Schema Registry will fight you on the way there. A live demo runs the bug and the fix back to back: same load, same hero, one change. If you build with Kafka, you have probably shipped a version of this bug. You will leave able to spot it and fix it before it pages someone. 👉 **He Who Must Not Be Migrated** *by Nicola Corti* **Speaker Bios:** 🗣 Oliver Okrongli Oliver has been shaping and creating software from backend to frontends. He is the author of TestBalloon, a next-generation Kotlin test framework. Before, he has helped to maintain Kotest, and contributed to several libraries of the Kotlin ecosystem as well as the Kotlin compiler. Can be found on GitHub (OliverO2) and the kotlinlang Slack (Oliver O). When not developing, he is most probably in deep talks, dancing, snowboarding or F18 catamaran sailing whenever he gets a chance. 🗣 Yonatan Karp-Rudin Yonatan Karp-Rudin is a Staff Engineer at Billie, building event-driven systems in Kotlin and Spring Boot. Off the clock, he plays with AI agents and builds random tooling, trying to hand off as much of his own workflow to a machine as he can. The rest of the time he's brewing mead or deep in a video game. **🗣 TBD**

We are happy to invite you to our next iOS meetup. This time we cooperate with the amazing 42 Berlin to share the knowledge and experience in iOS development. 18:00 Doors open 18:30 Welcome on campus **18:45** **— Sebastian Hagedorn, director of Engineering at Clue, presents "The Sensitive App".** Is your app really working, or just not crashing? “The Sensitive App” reports subtle bugs regardless of origin, and validates your assumptions in production so you don’t have to resort to guessing or praying. Learn how to turn your app into the first line of defense for your entire system’s health! **19:45** **— Dmitry Kurkin, lead Mobile Engineer at SuperNext, presents "Lessons that iOS Native Project could learn from ReactNative in agentic development".** We'll inspect the components of the React Native engine that provide faster feedback and boost agentic iterations.

Do you like to play football - but relaxed and not with competitive or aggressive players? Are you a bit lazy, a bit old, a bit unfit or not so talented? Then Lousy & Lazy Football is the right thing for you! We are a group of friendly people who just want to have a relaxed kick. All genders, ages (+18) and nationalities welcome. Feel free to join the waitlist even if it seems long - sometimes we make the event larger and play on two pitches (24 players, four teams) or even three pitches (36 players, six teams), depending on demand. Note: We do not allow high-studded football boots during our sessions. To avoid injuries, we only play with "Multinocken" (multistuds) or shorter. Please have a look here: [link](https://www.11teamsports.com/de-de/fussballschuhe/multinocken/). Lousy & Lazy rules: 1. **Don’t be competitive - fun only! Enjoy the workout, nice people, wonderful weather and magic ball moments** 2. **No emotional shouting, no telling other players where to go and what to do** 3. **No hard tackling/sliding** 4. **Avoid injuring yourself and other players at all costs: Tight situation? Give up the ball rather them going all in** 5. **Support less fit and less skilled players by giving them the time and space to play the ball, don't intercept passes to and from them. Bonus points: Make them shine!** 6. **Don’t dribble past multiple players (trying to take on one player is fine)** 7. **Don’t close down the defenders too quickly. Give the team a chance to play the ball out.** 8. **Rotate the goalkeeper** 9. **Be a teamplayer** 10. **Come regularly and be reliable with your RSVPs**

**Abstract:** Motivated by the challenges of detecting extremely rare failures in sophisticated circuit design specifications, we study the problem of efficiently identifying multiple disjoint regions of interest (ROIs) — regions of a continuous, high-dimensional parameter space where a complex, expensive-to-evaluate target function falls below or above a pre-specified threshold. We reframe this problem as a Bayesian sequential decision-making problem and, more broadly, as an instance of strategic agent behavior in continuous spaces: an agent that must allocate a hard evaluation budget intelligently, updating its belief about the unknown function after each observation and choosing the next query to maximize coverage of all disjoint failure regions rather than convergence to a single optimum. This is a *hybrid* event. To attend online, join us on Zoom here at 6pm: [https://iit-edu.zoom.us/j/89379230295?pwd=NdETyE5sdYuSrvsrBZXSBFkUESBVkg.1](https://iit-edu.zoom.us/j/89379230295?pwd=NdETyE5sdYuSrvsrBZXSBFkUESBVkg.1) Meeting ID: 893 7923 0295 Passcode: 5t5WYn **Sponsor**: Grainger will provide the meeting site, as well as snacks for the onsite participants. * **Address:** 222 W Merchandise Mart Plaza, 18th Floor, Chicago, IL 60654 * **Grainger's Overview:** W.W.
