Together with Capgemini, we’d like to invite you to our talk in June. This time, we’ll be discussing spec-driven development with Simon Martinelli. **Spec-Driven Development in Practice: How AI Simplify Full-Stack Java** AI is transforming how we develop software, but many teams still treat code as the source of truth, leading to outdated documentation and hidden business logic. What if specifications became the single source of truth instead? This session introduces Spec-Driven Development (SDD) and the AI Unified Process (AIUP), a practical approach in which developers write clear, structured requirements, and AI generates everything else: diagrams, code, and tests. When requirements change, the system stays consistent automatically. Based on a real-world Java project built with Spring Boot, jOOQ, and Vaadin, the most productive and secure web framework for Java, you’ll see how SDD keeps business rules, data access, and UI perfectly aligned. Join this session to learn how AIUP helps Java developers deliver applications faster, with less boilerplate and more focus on what really matters: understanding the domain. Most teams still treat code as the source of truth, leading to outdated documentation and hidden business logic. In this session, you’ll learn how Spec-Driven Development (SDD) and the AI Unified Process (AIUP) let you define requirements once and generate consistent Java code, diagrams, and tests automatically. Based on a real project with Spring Boot, jOOQ, and Vaadin, this talk shows how to build faster, safer, and more maintainable full-stack Java applications. **Simon Martinelli** Simon Martinelli is a Java Champion, Vaadin Champion, and Oracle ACE Pro with over three decades of experience as a software architect, developer, consultant, and trainer. He is the creator of the AI Unified Process (AIUP) and a strong advocate of Spec-Driven Development. As the owner of Martinelli LLC, he coaches teams to get up to speed with AI-driven development. He regularly shares his insights through international conferences, articles, and his blog, Keep IT Simple (https://martinelli.ch), where he writes about AI, architecture, and modern Java development. He is also a lecturer at two universities in Switzerland, where he teaches software architecture, persistence, DevOps, and cloud-native development.

**Join us for our next Machine Learning in Healthcare meetup in Berlin — proudly sponsored by the QUEST Centre!** Pizza is still back! We are very happy to announce our speaker **Frank te Nijenhuis**, who is a PhD candidate at the ICAI Stroke Lab at Erasmus MC in Rotterdam. With a background in medicine and computer science, he develops deep‑learning models to support real‑time clinical decision-making during stroke treatment. **His talk´s title is:** **Bridging the Implementation Gap in AI for Stroke Interventions: Challenges and Opportunities** **Abstract:** In recent years, rapid advances in artificial intelligence (AI) have led to a proliferation of AI models in medical imaging. However, despite promising performance in research settings, many of these models have yet to translate into meaningful clinical impact. In this talk, Frank will highlight several AI models developed for stroke imaging and examine the barriers that hinder their implementation in clinical practice. He will explore potential pathways to overcome these challenges and conclude with an interactive discussion on co-creation as a strategy to bridge the gap between innovation and real-world adoption. *** 📍 **Location:** “Atrium” conference room, 5th floor, Spreepalais, Anna-Louisa-Karsch-Straße 2, 10178 Berlin 🕕 **Doors open at 6:00 pm** — Talks start **at 7:00 pm!** * 6:00–7:00 pm — Arrival, food, and networking * 7:00 pm — Welcome by the hosts, followed by the talk + Q&A * 8:00 pm — More networking (and possibly more pizza) ⚠️ *Pro tip:* Sometimes only one of the four elevators is working! 📢 **IMPORTANT:** If you RSVP but later realize you can’t make it, *please release your spot* so others can join. *** This meetup is made possible with the kind support of the **QUEST Centre for Responsible Research at BIH**, who are providing both the venue and the delicious refreshments.

Everything in the universe vibrates: from the whisper of a leaf to the pulse of the stars. Sound is the primordial heartbeat of creation, and music, its universal language. For humans, singing is not just a creative expression; it is a path to transcendence, a bridge between the mundane and the divine. The Voice, our most intimate and sacred instrument, resonates with ancestral echoes. Since time immemorial, it has been used in healing rituals, as a channel for spiritual connection, and a key to higher states of consciousness. When we sing with sacred intention, breath, mind, and heart merge into a harmonious flow that transports us to deep peace and a precious state of contemplation. Sacred singing opens an inner space of living silence, where vibration becomes a healing dance that harmonises our being. Schedule (draft) 6 pm Doors open. 6:15 Start. **Singing together.** 8:45 pm Sharing food & connection. Rearranging the room. 9:30 pm End Doors close at 6:15 and open briefly at \~6:45 and \~7:15, for late-comers. Times within the event are approximate. **DONATION** Standard at 20€ (both: 30€) Supporter 25-50€ / Supported 5-15€ or write to [yaya.yala.amor@gmail.com](mailto:yaya.yala.amor@gmail.com) Looking forward to seeing you there! :)

Chitta Walks is for people whose days move fast, while the mind never fully lands. Thoughts keep looping even when nothing is urgent. The body moves, but attention is elsewhere. Over time, this disconnect drains clarity and ease. This walk is a simple reset. We meet in Berlin’s Tiergarten and walk at a gentle pace. Parts of the walk are in silence, with light guidance and a few short prompts. The walk itself is the practice, bringing body and mind back into the same moment. No apps. No performance. Just a clear space to slow down and notice what is happening. If you want to slow down without withdrawing from life, join a Chitta Walk. ✨ **What to expect (approx. 90 minutes):** * A short arrival and orientation * A guided silent walk (phones off, no conversation) * One concise science-based impulse on attention or stress * Optional reflection in pairs or small groups * A simple takeaway or experiment for daily life 🚶**Who this is for:** * Professionals, creatives, and people in transition. * People who feel mentally busy and want more clarity and balance. * Those curious about mindfulness, but grounded and practical. * Anyone comfortable with silence and gentle self observation. 🔔 **Practical notes:** * Duration: 60-90 minutes * Wear comfortable shoes and weather-appropriate clothing * No prior experience needed * Group size is limited to keep the space quiet and focused 🧭 **Facilitator:** My name is Partha Sarathi, you can call me PS. I have lived in Berlin for over 12 years. With a background in physics and materials science, my interest in mindfulness grew through personal experience with stress and health challenges. I facilitate the space and structure of the walk, inviting shared exploration rather than instruction. 🤔 **Why Chitta Walks?** Chitta is a Sanskrit word referring to the mind or field of awareness, used here in a practical, non-religious sense. Chitta Walks is about noticing how the mind works by slowing down and walking together. Mindful walking makes thought patterns visible in real time, while moving and sensing in the world. The name points to a simple capacity: noticing what is happening in the mind without immediately trying to fix, judge, or optimize it. 🌿 **Possible effects:** A calmer nervous system. Clearer attention. A felt sense of being more present in your body. Subtle insights into how your mind reacts under everyday conditions. A quieter, more grounded way of moving through the city. **Come as you are. Walk. Notice. Leave with a little more space inside.**

Tired of dating apps or surface-level social events? This is different. Relational Labs is a guided connection experience for singles who want more honest, playful, emotionally intelligent interaction — without performance, pressure, or endless small talk. This is not speed dating. Not networking. Not “pitch yourself to strangers.” It’s a facilitated relational container rooted in psychology, emotional intelligence, attachment work, social dynamics, nervous system awareness, and real-world human connection — made practical enough that you can actually live it instead of reading another 50 books about it. ## What happens • A 2-hour guided online relational experience • Real-time connection exercises designed to create authentic interaction • A format that adapts in real time to whoever is present • Optional participant-led in-person continuation afterward • WhatsApp connection thread after the session ## This may be for you if: • You’re tired of shallow or repetitive social spaces • You want deeper connection without forced intimacy • You enjoy personal growth, psychology, communication, or relational work • You’re open to meeting people in a more intentional way ## Important This experience runs with whoever is present and takes its own shape each time. Sometimes expansive. Sometimes intimate. Both are the real thing. Booking happens through our website. 👉 Reserve your spot: [https://consciousconnectionsclub.com/join](https://consciousconnectionsclub.com/join) Optional in-person continuation: same day or within 48 hours depending on the city Most people come alone. People often leave surprised by how quickly strangers can feel human, warm, honest, and real. Sometimes awkwardness turns into ease. Sometimes curiosity turns into chemistry. Sometimes people simply remember what it feels like to actually connect again.

You're in the right place.** For the first three weeks, we'll have on-site instructors ready to walk you through the basics in the first 30 minutes — no experience needed, no pressure, just good vibes and a little coaching. Our volunteers are also on-site every Monday to get you settled on the courts, introduce you around, and make sure you leave with at least a few new faces in your contacts. **How it works:** We run open play — meaning you'll rotate courts AND partners throughout the night. Winners stay for one round before rotating, so there's always someone new to meet, rally with, and maybe grab a drink with after. Maximum mingling. Maximum fun. **[Ticket & Registration is linked here!](https://www.eventbrite.com/e/summer-pickleball-but-everyones-single-datecolumbus-tickets-1990356562056?aff=oddtdtcreator&keep_tld=true)** **What's included:** * Paddles available every week (or bring your own!) * Locker room on-site * Full restaurant + bar at Paddle Taps * Every Monday, 6:00–8:00 PM for 8 weeks * Eat, drink, and mingle during and after play * **Ready to meet your pickleball partner (and maybe more)?** Grab your spot now — courts fill up fast and so do summer schedules, see you soon :)

Join the Columbus AI community for a special event. **Battle of the Personal Agents** is your chance to see what people are actually building with AI agents and personal automation systems. Whether you’re running OpenClaw, Hermes, or a completely custom solution, bring your agent and show the community how it works. We’re interested in real-world implementations: the problems your agent solves, how you use it day-to-day, how it’s hosted and managed, how you built it, and why you’ve chosen to keep using it. Live demonstrations are encouraged, so be prepared to show your code, architecture, workflows, and your agent performing real tasks. This is less about polished presentations and more about sharing practical experience, comparing approaches, and learning from one another. If you’d like to present, please contact Chris Slee (via meetup) before the event so we can allocate enough time for everyone’s demonstrations. Come ready to show what you’ve built, discover what others are doing, and maybe find a few ideas worth taking home. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
