While we are approaching the middle of the year and KotlinConf is just over - we are thrilled that Trade Republic hosts us again! So mark the date! **Line-Up:** 👉 **Lists, Sequences, and Flows: Scaling Data Processing in Kotlin without Melting Your Memory.** *by Daniela Valero* In this talk, Daniela shares her journey of meeting a major backend deadline while managing a data pipeline's memory footprint. You’ll learn how to transition from eager List operations to lazy Kotlin Sequences and jOOQ Streams (using database fetchSize chunking) to keep memory usage flat. Finally, we’ll explore using Kotlin Coroutines and Flow to introduce safe concurrency so your data processes quickly without straining your database. 👉 **The show must go on** *by Blagoja "Baki" Stamatovski* **👉 TBD** **Speaker Bios:** 🗣 **TDB**

The next **Berlin C++ Meetup** hosted by think-cell takes place on **Tuesday, May 26**. Join us for an evening with the Berlin C++ community! This meetup is a chance to step away from your day to day work, meet other developers, exchange ideas, and have real conversations about modern C++ in a relaxed setting. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- ## **Talk** ### **Contract assertions on virtual functions** *Timur Doumler – Citadel Securities* Contracts assertions were introduced in C++26, but they cannot be applied to virtual functions. To close this gap, we first need to answer the question: how should contracts assertions behave in the presence of inheritance and runtime polymorphism? In this talk, Timur explores why this problem is harder than it looks. He reviews existing approaches from other languages, such as Eiffel, D, and Ada, highlights why they don’t fully translate to C++, and outlines the key design challenges involved. He then presents a concrete proposal for how contract assertions on virtual functions could work in C++, balancing correctness, safety, and usability. Along the way, the talk touches on good API design, the true meaning of the Liskov substitution principle, and how to reason about program correctness. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 📅 **Date & Time:** Tuesday, May 26, 2026 – 18:30–21:30 📍 **Location:** Le Wagon Coding Bootcamp, Rudi-Dutschke-Straße 26, 10969 Berlin 🕒 **Agenda** 18:30 – Doors open 19:00 – Talk + Q&A 20:40 – Pizza, Drinks and Networking \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **RSVP now to save your seat!**

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
