**IMPORTANT: please reserve your seats at [eastwestcomedy.com](eastwestcomedy.com) in addition to RSVP on Meetup to guarantee a seat!** THE Special show for your Friday night! Guest star headliner + experienced support acts from all over the world in a professional venue! **Headliner: [Elena Gabrielle (AUS)](https://instagram.com/elenagabrielle "https://instagram.com/elenagabrielle")**. **Support: Devansh Sharma (IND), Struan Logan (SCO), Chris Loar (USA).** This Australian born European based comedian appeals to sold out audiences across the globe with her witty, no-holds barred approach to stand-up comedy and because of this, has seen her go viral with **30 million plus views on YouTube** to date. Her embarrassing date stories are delivered in an intuitive storytelling style which cuts through cultural divides and is enjoyed globally. After touring non-stop for 4 years with 'Story Party Tour' (which saw her perform over 700 shows in that time and in 65 countries) and a sold-out run with her first solo tour "DIRRTY" in 2021, Elena is now embarking on her second worldwide solo tour with her show “Addickted”. Multi-talented, she is trained in Musical Theatre at Australia’s prestigious and premier acting University NIDA (National Institute of Dramatic Art).

**Everyone's welcome ❤️** Every Friday evening we meet up by the Spree — music playing, people arriving from all over the world, and a night that usually goes way longer than anyone planned. No agenda. No organised icebreakers. Just a relaxed spot by the river where you can show up, grab a drink, and actually meet people worth knowing. We've been doing this for over 8 years, and the best thing about it is still the same — you never quite know who you're going to end up talking to. Come solo, come with friends, come fresh off a flight. The crowd is always a mix of Berliners, expats, travellers, and people who just moved here and are figuring it out. After a while the group usually spreads out to bars or clubs — or just stays by the water. You go wherever the night takes you. **Stay in the loop — join our Telegram group:** Spree Ravers → https://linktr.ee/clockworkbanana 📍 By the Spree, next to Schlesisches Tor U-Bahn — opposite the East Side Gallery, right by the Cage on Water → [https://maps.app.goo.gl/vj1DhSP3apijCmRbA](https://maps.app.goo.gl/vj1DhSP3apijCmRbA) 🕒 From 9 PM — people arrive gradually, so if it's quiet at first, just hang tight See you Friday ✨

**⭐ DOORS OPEN AT 19:30. PLEASE ARRIVE BEFORE 8PM! ⭐** The Creative Code Stammtisch is a casual show-and-tell for artists, makers, designers, coders, performers, learners and anyone interested in the use of computing skills for artistic expression. The event is free and open to all, regardless of age, origin, gender or experience. Beginners and first-timers should feel especially welcome! You don't have to be a coder yourself 😃 HOW TO FIND US? Find Prachtsaal Studio by crossing the courtyard next to Cafe Augusta on Jonasstr. 22, 12053 Berlin. WHAT SHOULD I EXPECT? We start with quick introductions, then open the floor to anyone who wants to present something. There are usually around six 10-minute slots available, plus time for questions from the audience. First-timers are encouraged to share their work. Topics range from net art to computational design and interactive installations all the way to wearable electronics or generative poetry. If you’re wondering whether your own project might fit, take a look at the [Stammtisch archive](https://creativecodeberlin.github.io/Stammtisch/) to see what others have shared in the past. This event is *not* just for coders! New-media artists and anyone working with technology in their art are very welcome to share. If you enjoy art and/or technology, you’ll likely have a great time, and maybe even learn something new! BEGINNERS WELCOME! If you’re new to creative coding, you can find beginner-friendly resources at [creativecode.berlin/learn](https://creativecode.berlin/learn). THIS IS YOUR SPACE We do our best to create a welcoming environment for all people regardless of race, ethnicity, color, religion, gender identity, sexual orientation, national origin, age, disability, or genetics.

**🎟️ Registration for this event is done via the MoT page, not on Meetup.** **Register here 👉 [https://www.ministryoftesting.com/chapters/mot-berlin/events/mot-berlin-050626](https://www.ministryoftesting.com/chapters/mot-berlin/events/mot-berlin-050626)** Hello Berlin, we're back! After the last get-together where we started shaping the Berlin chapter, we're excited to invite you all together again for an insightful evening focused on AI Test Generation, community discussions - and YOU! The evening will bring together industry experts to share their knowledge, ask questions and learn something new. Whether you're a developer, QA engineer, or tech enthusiast, you'll gain valuable perspectives and practical experiences. **✍ Registration:** Reserve your spot by clicking "Attend" on this page. Note - Participation is limited to 30 participants only. **❓ What to Expect:** • Talks from experienced speakers • Networking with the local community • A chance to speak on stage with 99 second talks • Swag and goodies from MoT and our sponsors, TestMu AI **🎤 Quality Talks** *AI Test Generation: What Actually Works (and What Doesn’t)* *Ruslan Strazhnyk - Founder & CEO @ QualityMax* Every QA tool vendor will tell you AI generates perfect tests. After building an AI test generation platform - and dogfooding it on our own codebase - I can tell you what actually happens. This talk is a practitioner’s honest debrief. I’ll walk through two years of running multi-model AI against real web apps: what produces usable tests, what produces confident-looking garbage, and where the failure modes hide. Specifically, I’ll cover: * Why reading code isn’t enough - AI generates plausible tests from source, but they fail on real UIs. Crawling the live app changes everything. * The selector problem - LLMs reach for brittle CSS selectors by default. How to force better strategies without prompt-engineering every call. * Assertions that rot - AI loves asserting exact text and prices. Why your generated suite breaks on the first content change, and how to catch it before CI does. * Multi-model routing - no single model wins at everything. What we learned running GPT-4o, Claude, and Gemini on the same flows. * Self-healing in practice - the gap between “it healed” and “it healed correctly.” You’ll leave with a clear framework for evaluating any AI test generation tool - or building your own - based on what the output actually does under pressure, not what the demo shows. Level: Intermediate, assumes familiarity with Playwright or similar frameworks *99 Second Talks* Have something to share about testing, tech, or teamwork? Whether it's a win, a challenge, or a wild idea — you’ve got **99 seconds** and a room full of curious, supportive people. Take the stage! **🕰️ Schedule:** 17:45 - Doors open (arrive early to mingle!) 18:00 - Welcome and Introduction 18.15 - Ruslan Strazhnyk: AI Test Generation: What Actually Works (and What Doesn’t) 19:15 - 99 Second Talks and networking with food and drinks **📍Location:** Assecor GmbH, Storkower Straße 207, 10369 Berlin 👀 **Want to speak at this or the next MOT Berlin event?** We are already planning our next meetup in July - and we're always looking for speakers.

The course will start this Saturday at 10am. It will be in studio R at CCB studios. [https://maps.app.goo.gl/rFovxE7eG7HV6uB46](https://maps.app.goo.gl/rFovxE7eG7HV6uB46). Buzz for CCB studios and then walk through to the second courtyard. We will try to start right around 10. There will be tea available. Please dress in comfortable clothes, maybe wearing a few layers. Theres some blankets, yoga mats, cushions and chairs in the room that you can use. The plan will be for us to do some small discussions at the top and then start discussing theory before doing some meditations of increasing length and then closing with some time for Q & A. We will take a short break in the middle as well. The plan is to go from 10-12 roughly but we may end a little closer to 11:30 depending. This week will function primarily as a simple introduction to meditation and some topics in the space but we will also discuss what the Jhanas are. Looking forward! Any questions please just message me.

Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. We are usually inside and to the right. Ask the barista/bartender if you can't find us.

An opening of an art exhibition is a nice occasion to catch up and hang out. No agenda, just art, wine and chat. *** KIT Berlin ([@kitstudioartspace](https://www.instagram.com/kitstudioartspace)) invites you to an exhibition of paintings by Wiola Stankiewicz [@wiola_stankiewicz](https://www.instagram.com/wiola_stankiewicz/) “Now it Makes Sense, Isn’t It?” and a musical performance by Antonio Bastos [@antonio__bastos](https://www.instagram.com/antonio__bastos/) Now It Makes Sense, Isn’t It? continues the “Emotional Algorithm” project — a series of paintings built from intuitively selected screenshots, private photographs, and images found online. The images are combined like an emotional bajaderka (a Polish layered dessert traditionally made from mixed leftovers, fragments, and combined remains) — sometimes through color, contrast, or an unexplainable feeling that they simply belong together. The works explore screen aesthetics and digital ways of perceiving images. Meaning often appears only later. And sometimes not at all. Wiola Stankiewicz is a visual artist born in Elbląg, Poland, currently living and working in Coimbra, Portugal. Her practice focuses on painting, collage, and assemblage, using mixed media techniques and experimental material processes. Working with icons of popular culture, landscapes, found images, and photographs from her personal archive, Stankiewicz builds a coherent and autonomous visual language based on intuition and process. Her works function as images of an open character, in which meaning emerges from the relationships between image, material, and gesture. Antonio Bastos turns vulnerability into stage, community into sound and instinct into creation. From electronics to tradition, from improvised lyrics to shared movement, his music is born live and unfolds into a visual, emotional experience. With dozens of releases and festival shows, he was awarded People’s Choice at the IPMA (USA), blending performance with community creation — involving choirs, schools and local groups of all ages. Each concert is a seed sown in the territory, where the audience also becomes creator.

**Nerds, Creatives & Dreamers** is a small, curated gathering in Berlin for two kinds of people who almost never end up in the same room: the ones who build things with code, and the ones who build things with imagination. Developers and painters. Engineers and writers. Founders and photographers. In daily life these worlds rarely collide — here, that collision is the whole point. Just a good space, a deliberate mix of curious people, and the freedom to let the evening unfold. Come ready to be surprised by who you meet and where the evening takes you. A room full of curious humans. We’re here to socialize as human beings. And if you do exchange contacts — make it personal, not transactional. **🛠 If You Build Things** · Developers & Engineers · Designers & Product People · Founders · People Who Code for Fun **🎨 If You Create Things** · Writers & Journalists · Photographers · Artists & Painters · Anyone With a Side Obsession 👉 **You can also join via Luma if this event reaches capacity: https://luma.com/0y2yd2q4** Please RSVP “yes” only if you can make it, so we can save a seat for you and others on the waitlist. **📝 Note:** You are welcome to attend our social meetup! The event is free. The space is generously hosted for us — the only thing we ask is that you support it by buying a drink, etc. A small gesture that keeps evenings like this possible. **🤝 Community:** This is a space built on curiosity and respect. We keep it that way — for everyone.

## 🤝 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. ###

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

**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.
