**⭐ NEW LOCATION! ⭐ 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. **NOTE: NEW LOCATION!** 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).

There is no need to be at the beginning of the cohort to build. Complete beginners welcomed! 📌 By the End of a Full Cycle, You should Have 🎯 A working project in your own GitHub repo 🎯 A small but real portfolio piece you can demo or write about 🧠 **Current Project** This cycle’s shared project is an **image-based knowledge extraction system**. In **Week 7**, we celebrate and present. This is our **Showcase Night**. Participants will: * Present their project (5–10 minutes each) * Demo their pipeline or flashcard system * Share challenges, lessons learned, and technical decisions * Give and receive thoughtful feedback We’ve come a long way — from raw images on our phones to a complete, working portfolio project — and this week is about learning to clearly explain your ideas, your challenges, and the technical decisions behind your work. \*\*\* **👋 Who Is This For?** 🔹 Beginners who learn best by doing — no prior experience needed 🔹 Career switchers from product, engineering, design, marketing, or other fields who want to break into data 🔹 Analysts, engineers, and PMs looking to sharpen their skills or build real-world projects 🔹 Data professionals who want a creative playground outside of work 🔹 Anyone with big questions and a love for learning through experimentation \*\*\* **BUILD.

Join our Backgammon Meetup to play, socialize, and enjoy this classic game! Everyone’s welcome! Whether you’re a beginner or an experienced player. Expect fun, friendly games, laughter, and new friends. 👉 Please RSVP only if you plan to attend. 👉 Bring your own set if you have one. *** **How to Play (Quick Guide):** * Each player has 15 checkers and moves them toward their home board. * Dice rolls decide how many spaces you can move. * Land on an opponent’s single checker to send it to the bar. * Once all your checkers are home, start bearing off (removing them). * First to remove all checkers wins! *** **Fun Fact:** The Origin of Backgammon: Backgammon is one of the oldest known board games, with roots deeply embedded in the ancient civilisations of Mesopotamia. But it is in Persia, where the game truly flourished and evolved into what we now know as 'Takhte Nard'. Archaeological findings suggest that early forms of backgammon were played in Iran over 5,000 years ago. Artifacts such as game boards and dice have been discovered in sites like 'Shahr-e Sukhteh' (The Burnt City), indicating the game’s ancient origins.

Welcome to **I WRITE**, a gentle space for anyone who wants to write—quietly, freely, and without judgement. We are a Berlin community of writers who gather together weekly to write, talk and recharge after a long week.

I started this writing club back in May 2025. Since then, it has been hosted weekly at the Heinrich Schulz Library (who is kind enough to allow us to use this room for free). Over this time, I’ve been privileged to meet some of the most creative and kind minds in Berlin. And I would be happy if you joined us. Whether you're an experienced writer or just at the beginning of your journey, you're welcome. If you know how to hold a pen or how to type, there will always be a space for you.

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. **Answers for common behavioral questions** \- at the beginning\, I will read some common interview questions\, explain what they mean\, and give the correct answers\. 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.

Hey everyone! I’m organising a co-working + socialising session for all of us who like to work on something (e.g. our own project, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have both **socialising** AND **working**, we will be using the so called “Pomodoro” technique: **50min of deep work** (silent), followed by **10min of break** to socialise. Then repeat! If you get into flow, you're also welcome to skip the breaks. It’s an effective way to stay focused - you can read more about it [here](https://en.wikipedia.org/wiki/Pomodoro_Technique). Anyone from any background is welcome, whatever project you are working on or whatever is your personal background. I (the host) speak English and German, so either is fine :-) ——————————————————- AGENDA: * **15min Intro** * Get to know everyone, talk about what you will work on today * **Pomodoro Session** (3x) - *Each Pomodoro session consists* *of...* * ...**50min** of uninterrupted “deep work” (no talking, no interruptions, no phones) * ...**10min** of break: share your progress with others, talk about what you are stuck on etc. * Repeat * Conclude and celebrate your progress Share your progress, socialise and get to know others 😊 ———— We'll be at the Social Hub Berlin (they have a food menu in case you get hungry). The structured part will end at 2:30pm, but you're welcome to stay longer, go for lunch together, or leave earlier. See you there 🩵 **\*\*We'll reserve the long table. Please update your RSVP in advance if you can't attend!\*\***

Come along, grab a coffee, shut up, and write! We will do at least two sessions of each 45 minutes of writing and two breaks. We will start the first writing session at 11:15. **For space reasons, we are limited to a certain number of attendees, so please update your RSVP if you can't come**. We often have a large waiting list, and not updating your RSVP or not showing up if you do RSVP yes means that others miss out. We also ask that if you do change your RSVP, do it with reasonable notice. Thanks! We typically take over all of the cafe, but try to share tables if you can to allow space for other customers. If you are new, come and say hello, as we know that suddenly going quiet for 45 minutes and staring at that blank page can be intimidating when it's your first time. We have a lot of long-term regulars who will be happy to help you feel welcome. In between sessions, we have a Telegram chat: https://t.me/joinchat/ERW3pxD5kfELGeWs9SUhjw For more information, visit [https://shutupwrite.com](https://shutupwrite.com/).

Come join us at Nova Labs for our monthly lockpicking meeting! We meet every third Wednesday at the Nova Labs Fairfax location at 3850 Jermantown Road. Learn about locks, lockpicking, lock modifications, and even lock smithing in our classroom environment. No tools, skills, or knowledge required, but feel free to bring any of those things with you! Our meetings are overseen by one or more locksmiths.

Want to mess with some electronics? Or perhaps contribute to HacDC's main group project? HacDC's latest event brings hardware projects to the community. We will focus primarily on the main project (Space Blimp!) but please feel free to bring some of your own projects to show off and work on!

**Agenda:** * 6-6:30 pm: Networking and food/drinks * 6:30-7:15 pm: Announcements and presentation * 7:15 pm-7:30 pm: Q&A and close-out **Hacking the Stack: Using OpenSearch Dashboards as an Application Framework** Most developers treat OpenSearch Dashboards (OSD) strictly as a visualization layer—a place for charts and graphs. They are missing the bigger picture. OSD is a powerful, untapped environment for full-stack application development. In this session, we peel back the architecture of **an enterprise-grade risk, compliance, and security platform built entirely *on top of* OSD**. We moved beyond simple plugins and pushed OSD to its limits to create a seamless, interactive application experience. Join us for a deep dive into the engineering reality of the OpenSearch stack, including: * **The Analysis:** Why the OpenSearch stack beat out the competition. * **The Build,** **Beyond Visualization:** How to implement custom React components to build complex workflows and interactive UIs within OSD. * **The Integrations:** Integrating Wazuh for agent management and ingesting data at scale. * **The “Gotchas”:** Honest, real-world lessons on data handling, state management, and what to look out for. **If you are ready to push your plugins from “reporting tools” to “robust software,” do not miss this session!**
