After hopping across various Berlin venues, we’re thrilled to return to Saftladen for the second edition of *Level Up Your Folds*! Big shoutout to this non-profit (and a very *professional* one, mind you 🍊) indie game developer collective for hosting us again – couldn’t ask for a better creative playground! 👾 Food or snacks for sharing during the origami session are very welcome, so bring them on! Here's an overview of what you could expect: * **Special format of 2x presentation** by our beloved origami masters, followed by **guided collective folding of a model** of their choice! * **Mandatory donation** (amount of your choice) – this supports essential costs like the Meetup subscription and keeps our community thriving 🌱 You can either submit a **physical donation** to the event host in person or make a **digital donation** **[here](https://paypal.me/origamiberlin?locale.x=de_DE&country.x=DE)** (and inform the host afterwards). * In-person folding practice for all levels – beginners and experienced folders are equally welcome. * Origami paper + model instructions will be provided (from the host’s collection, for reference only). Feel free to bring your own favorite sheets or tools! * Photos may be taken for memories & our archive (Meetup, Instagram, Telegram) – let the host know if you prefer not to appear. * **We kindly encourage everyone to buy at least one drink (€2 each) to support [Saftladen](https://saftladen.berlin/) for hosting us!** ⚠️ **RSVP Policy – Please Read** ⚠️ Our community has grown a lot since its birth in August 2024, which is amazing — but it also means we need to handle RSVPs more carefully: * RSVP opens **7 days before** each event (apart from short-notice events) and closes at **noon on the event day**. * Please cancel your spot or contact the host directly (via Meetup message function or our [Telegram channel](https://t.me/+T4URs80l2ig3NWNi)) by **noon on the event day** if you can't make it last minute. * Members with **2 no-shows** (without notice) will be removed from the group unless a valid reason is provided. Thank you for helping us keep our community respectful, reliable, and fun! 🙏 Get in touch if you have questions anytime and see you all at the folding tables very soon! 👾🍊

🕢 Doors open at 18:30 and sessions start at 19:00. Freestyle vocal workout at and play session. €8-20 😌 Flow is a state of being… an experience when you allow yourself to be 100% fully engaged in the present moment in a feedback loop between clarity and satisfaction. It is an undeniable sensation where things seem to be more effortless, pleasurable, in sync, and you can easily sense a connection with something greater than yourself; this is what we will create…: • a connected and mindful meditation where it is possible to blissfully surf the cutting edge of the present moment together… • a game where it’s possible to feel excited and calm in the same moment, and everyone can win as much as they like… Scott Bolden, founder of Das Baumhaus Berlin will share some very easy, practical and effective methods developed during the last 12 years of facilitating the “Improvisational Groove Orchestra” (I.G.O.) improv vocal jam sessions. Within 20 minutes participants learn to use the common sound space to create resonance in the form of improvisational music where it is quite common to experience some real flow moments… It is very easy to participate, no musical talent or training is required so anyone is welcome to join. All of the session is done with eyes closed to avoid visual distractions and keep focus on the co-created sound space. During these sessions we will also have short breaks for feedback and refreshment. Important – Please be on time. It is very important to understand the methodology and warm up in the group before joining in! 🎤 @21:00 - Freestyle vocal workshop and practice session. €8-15 Have you ever wanted to learn how to do freestyle vocalizations? Maybe you are on your way and would like to just have a fun workout session with other vocal freestyle enthusiasts. All levels welcome.

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!**

Join our Women’s Circle at "Das Kabbalah Centre" in Berlin, hosted by Rachel Wende. Language: English. This event is open for new and current students. Amount: EUR 05.00 - 15.00 [Register here](https://onehouse.kabbalah.com/de/events/womens-circle-rw-26mai26-1778598265129619/) Living a purpose-driven life is something we all strive for. Such a life promises that we are using our talents, sharing of ourselves, and working towards goals that are fulfilling and inspiring. Staying on the path requires daily effort and yet, with all the responsibilities that we have as women, sometimes that purpose-driven life seems like a worthy goal for sometime after we’ve fulfilled the needs of our partners, children, and jobs. Join us for an intimate women’s circle as we share insights and tools for how to revitalize our search for our purpose. Learn how to get out of patterns and routines that keep us from making the changes we deeply desire. Our path to fulfillment lies within each of us; we only need to tease it out. The Kabbalah Centre Berlin Hauptstraße 27 Entrance E / 1 Floor 10827 Berlin

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.
