**This is 100% non-profit. The 15€ sign up fee for everyone is only to minimize last-minute cancellations. The total sum goes to a bar-tap that everyone can use to order drinks until the amount is used up. ‼️NO REFUNDS‼️** **‼️Please don't just show up without RSVPing here and paying the 15€. We have a separate room that has limited capacity and a specific drinks agreement with the bar - so splitting up the bill won't become a mess.‼️** **Small update on how your money get's used from May 2024 onwards:** As of this month, meetup.com has started charging me 34€ instead of 16€ per month. I've decided to distribute this fee evenly among all us participants every month. Example: In the last 12 meetups, the average number of attendees was 17. With 17 attendees I would effectively collect 230€ (after fees). I would now substract 34€ leaving us with 196€ that go to the bar. 15% get's tipped to the wait staff, in this case 30€, leaving us with 166€ effectively to order drinks. Hope everyone is cool with this system. :) Website: https://www.pberg-engineers.me WhatsApp groups: Please come and join us on WhatsApp! \- "PBerg Engineers \- NEWS" \- Only organizers can post announcements or polls \-\> https://chat\.whatsapp\.com/EqMJMmlCZO6LOOfAoG4yTj \- "PBerg Engineers \- DISCUSS" \- Everyone can post \-\> https://chat\.whatsapp\.com/LPuo76J83gF6IZMLUcM4u2 Please join those groups now if you're interested. :) All skill/education-levels welcome! :) Lightning Talks: \- TBD We'll also have a brief "Jobs: Lost & Found section". **Location:** From the street you will have to enter the right hand Cafe Chagall (yes, there are 2).

Chitta Walks is for people whose days move fast, while the mind never fully lands. Even when nothing is urgent, thoughts keep looping. Sometimes you are moving, but mentally elsewhere. Other times the mind runs ahead, while the body feels heavy and stuck. Over time, that mismatch drains clarity, ease, and presence. 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, reconnecting body and mind in the same moment. No apps. No performance. No techniques to master. Just a clear container to slow down and notice what is actually happening. If you want to slow down without withdrawing from life, join us for 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 that refers to the mind or field of awareness. Here it is used 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 skill: noticing what is happening in the mind without immediately trying to fix, judge, or optimize it. Chitta Walks is about understanding how the mind works by slowing down and walking together. Mindful walking makes this visible in real time, while moving, sensing, and being in the world, not withdrawn from it. 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.**

Join this **Interview Simulation** session — to sharpen the skills for both interviews **and** architectural pitches. 💡 How it works The event is split into three parts: 1. **Most common behavioral & HR questions** \- you will receive a printed list of behavioral/HR questions and we brainstorm tips on how to prepare for them 2. **Interview Simulation (10 minute rounds)** – One participant acts as the interviewee and answers a round of behavioral and design-focused questions. Each other participant gets to ask him one interview question. 3. **Feedback Round** – The group provides feedback on communication, structure, and clarity. Constructive criticism is encouraged. 💡You will be asked: * **Behavioral questions** (“Tell me about yourself”, “Describe a challenge you faced...”) * **Technical questions** (based on your tech stack) * **Light design problems** (high-level reasoning, not code) No need to prepare anything in advance — just bring curiosity and an open mind. Feel free to bring your CV if you’d like feedback from others, or share a few words if you’re currently job hunting. If so, we will also brainstorm answers to more common questions that you were asked. Whether you’re preparing for an interview or simply want to grow as a software designer or architect, this session is for you.

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

Data Science Retreat presents 5 Machine Learning prototypes and projects by Batch 44 participants. **Free to Attend!** Hey Berlin Data Folks! We’re kicking off 2026 with our first data event of the year. Join us for project demos, fresh ideas, great conversations, and of course—pizza & drinks on us 🍕🍻 Don’t miss it! **Agenda:** **17:30** \- Drinks and Networking **18:00** \- Welcome & Introduction Followed by Project Presentations **Project Ideas:** **1\. AI/ML \- EV Battery Shape Classification** ***Project by Uma Maheswari Obbani*** The project aims to automate the detection and classification of used electric vehicle (EV) batteries by shape — cylindrical, prismatic, or pouch — using AI/ML and computer vision techniques. The goal is to provide manufacturers and recyclers with real-time insights about battery type distribution, enabling efficient sorting, inventory management, and safety compliance. **2\. Developing Scalable and Reliable Coffee Yield Forecasting Tools** ***Project by Dr. Juan Fernando Duenas Serrano*** The aim of the project is short term coffee yield forecasting improves planning and value creation across the supply chain, from farmers to roasters. Current yield estimation methods are not scalable and require specialized expertise. This project explores computer vision as a scalable alternative using smartphone images. A YOLOv8 object detection model counts unripe Arabica coffee cherries on branches. The model can estimate yield at tree or farm level with optional user input. A Gradio or Streamlit web app will demonstrate, evaluate, and extend the model’s potential. **3\. Classic Car Diagnostic Tool** ***Project by Lulezim Ukaj*** This project aims to develop a specialized AI-powered diagnostic tool for classic cars that leverages community knowledge from German automotive forums. Unlike modern OBD-II–based diagnostic tools, which dominate the market, this solution targets pre-1996 vehicles where standardized electronic diagnostics do not exist. **4\. Enhancing on\-site audience audio** ***Project by Thede Witschel*** This project develops an enterprise-grade AI platform that automates the extraction of ESG data, regulatory compliance checks, and peer benchmarking for companies. Utilizing NLP and machine learning, the system converts unstructured sustainability reports into standardized metrics, facilitating real-time compliance monitoring and competitive intelligence across various industries. Business Impact: Targets the rapidly growing ESG software market, serving investment firms, consulting companies, and institutional investors requiring automated analysis for portfolio decisions and regulatory compliance. **5\. Ludus Automated Game Balancing: An AI\-Driven Evolutionary Pipeline for Card Game Meta\-Stability** ***Project by Rami Aldrea*** This project addresses the critical and often labor-intensive challenge of balancing a complex digital card game meta, specifically focusing on a 70-card set. The primary objective was to develop and validate an automated, iterative pipeline capable of achieving and maintaining a stable, competitive game environment where no single card or archetype consistently dominates. The desired outcome was a game meta with a mean card win rate of 50%, minimal variance (ideally <5% standard deviation for competitive e-sports), and preserved strategic diversity, all while significantly reducing manual design time. **20:00** \- Open for networking **20:30** \- Wrap up We have limited seat so please RSVP soon. See you all at the event.

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** GitHub Copilot is rapidly changing how developers write, understand, and maintain code. Powered by generative AI and deeply integrated into modern development environments, Copilot acts as an intelligent coding assistant, helping developers move faster while maintaining quality and focus. In this session, we’ll explore what GitHub Copilot is, how it works, and where it fits into a real-world developer workflow. We’ll break down what Copilot can (and cannot) do, where it can be used, and how licensing differs for individuals and organizations. Most importantly, this talk goes beyond theory with a live, hands-on demo showcasing Copilot inside the IDE and on GitHub, demonstrating how it can assist with code generation, refactoring, learning new APIs, and accelerating day-to-day development tasks. Designed for developers, technical leads, and engineering managers, this session provides a practical introduction to AI-assisted development, highlights best practices for getting value from Copilot, and closes with guidance on how to continue learning and evolving alongside this rapidly advancing tool. Attendees will leave with a clear understanding of how GitHub Copilot can enhance productivity, improve developer experience, and fit into modern software teams today, not someday. **YouTube Link** TBA

## Learn Infrastructure-as-Code (the FUN Way) — Through Minecraft 🎮☁️ **Joint Meetup: Azure CBUS × Columbus HashiCorp User Group** What if learning Terraform and Infrastructure-as-Code didn’t feel like a whitepaper… but more like a game? Join us for a joint Azure CBUS and Columbus HashiCorp User Group meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| “The Azure Terraformer”\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts. In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft servers—while teaching the same patterns you’d use for production cloud infrastructure. ### What we’ll cover * Infrastructure-as-Code fundamentals using **Terraform** * Provisioning real infrastructure on **Azure** * Applying **IaC best practices** (immutability, repeatability, versioning) * How playful environments like Minecraft make complex concepts *click* * Why learning through experimentation beats click-ops every time ### Who should attend * Developers, platform engineers, and cloud engineers * Terraform users (new or experienced) * Anyone curious about Infrastructure-as-Code but tired of boring examples * Minecraft fans who want to see it used in a totally unexpected way No prior Minecraft experience required—just curiosity and a willingness to learn infrastructure the fun way.
