Sometimes we keep thinking about the same situation, emotion, or life question — but cannot fully see it from the outside. As part of my studies in Systemic Counseling (“Systemische Beratung”), I would like to create a small, professionally inspired reflective space for thoughtful and respectful conversations. In this reflection circle, one person at a time can share something that is currently on their mind, while the others listen carefully and later reflect on what they noticed, felt, or understood from their own perspective. The goal is not to give quick advice or “fix” problems. The goal is to discover new perspectives through attentive listening and structured reflection. ✨ No experience is needed. The format will be guided step by step in a calm and supportive atmosphere. 🌿 How it works 1️⃣ (10 min) Warm-up & casual conversation 2️⃣ (05 min) One person shares a personal situation or question while the others listen without interrupting Possible starting points: • A situation I keep thinking about • Something emotionally confusing • A transition phase in my life • A question I cannot fully answer yet • A pattern I notice in relationships/work 3️⃣ (05 min) The sharing person remains silent for a moment while the others gently reflect together. The focus is not on fixing or giving advice, but on sharing: • What touched me • What I noticed • What image or metaphor came to mind • What dynamic I sensed • What contradiction I observed • What emotion I felt while listening Participants speak with each other — not directly to the sharing person. This often creates the feeling of being thoughtfully and respectfully witnessed by a group. 4️⃣ (05 min) The sharing person responds: • What resonated • What surprised them • What felt meaningful 🌿 Communication Style • We listen without interrupting • We avoid immediately fixing or advising • Different perspectives are welcome • Everyone shares only what feels comfortable • Quiet listening is also completely okay 📌 Practical Details 📍 Le Quai Steffen – Gare de Luxembourg 📅 Sunday, May 31, 2026 ⏰ 15:00 – 17:00 👥 Small group: max. 7 participants 💶 Participation contribution: 8€ (to keep the group small and intentional) ☕ Food & drinks paid individually Looking forward to creating a warm, reflective, and professionally held space together. ✨

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** https://youtube.com/live/BltmWMH1zG0?feature=share
