For 2026, we are starting a new series of EventStorming deep dives. These will be like coding katas, except there's no coding, only sticky notes. In each of these sessions, we will explore a nuance of the EventStorming technique that we don't normally have time to go into during a more general workshop. What are we exploring this time? You'll have to show up to find out. As always, everyone is welcome. You don't need to be a software engineer to participate. In fact, it would be great to have more people who aren't software engineers. We're here to solve problems cross-functionally, not get into implementation details. As long as you care passionately about getting things right, then you belong here! This is a hands-on workshop. Be prepared to participate fully and add to the energy of the room. Looking forward to seeing you there!

We are back in the c-base! Do you already run NixOS and want to talk to other people or want an introductory session with some NixOS users. Just bring your machine! Usually there are no topics, we just sit in front of our computers, talk about stuff, debug some problems or review some PRs on nixpkgs. There are drinks usually available from the c-base bar. If you can't find us. just ask around or ask in irc (#krebs on hackint)

Liebe JUG-Mitglieder, wir möchten Euch herzlich zu unserem nächsten Stammtisch, der jeden ersten Dienstag im Monat stattfindet, einladen. Alles weitere kann im unserem Blog unter http://www.jug-berlin-brandenburg.de/ gefunden werden. Viele Grüße Sandra, Jan, Jörg und Oliver

**Please be aware - this is not a class. It's a practice for people who learn to dance.** Take your time to practice Salsa with your friends and friendly faces. We will adjust the music to the students that come - but generally, we will keep the music on the easy dancing side. After the practica (about 75 minutes), if people are interested, we will head to one of the bars nearby for a get-together. Often, you will have a teacher around, so you can ask him or her questions and get feedback as well. **IMPORTANT NOTES:** * While you are welcome to drop in - spots are limited. If you want to guarantee your spot - [please book it in advance](https://la-candela-salsa.de/salsa-friends-practica-and-meetup/). * This is not a Beginner class. For Beginner classes, we recommend to join our [Salsa Beginner Course](https://la-candela-salsa.de/salsa-beginner-course/). After 2-3 classes you should feel more free to attend this event. * The practica is 6 Euro. You can also use USC or any of our [memberships or packages](https://la-candela-salsa.de/prices/) if you'd prefer.

On the 3rd February we will host the next iteration of our monthly Audio Developer Meetup where **Svein Berge** will be giving a talk on ambisonics and **Christoph Schied** will be showing [Stracker](https://bleep.toys/stracker/). See below! As always, there will be a chance to network over drinks and pizza. Anyone interested in Audio development is welcome! Doors open at 18:00, talks start at 18:15. Please note: Attendance is **strictly limited** to people who have RSVP'd Talk details: **The principles of ambisonics** \- Svein Berge More talk details to follow shortly Svein Berge has a master's degree in electronics and acoustics from NTNU in Norway and a Diplôme d’Etudes Approfondies in lasers and atomic physics from Université Paris 6. He has worked as a software developer in the telecoms industry since the 90s and as an individual developer in the field of ambisonics since about 2009, where he created the Harpex decoder and Spacemic ambisonic microphone array among other things. He has been based in Berlin since 2011, where he runs the company Harpex Audio GmbH. **Writing a modern tracker, how hard can it be?** \- Christoph Schied When I started Shield Tracker as a spare-time project in December 2023, I was frustrated by existing hardware and software sequencers. I kept wondering, how hard can it really be, and with little background in audio programming I decided to find out. The project escalated quickly, now sitting at over 45k handwritten lines of code, including a custom UI framework driven by a domain-specific-language, a built-in programmable fantasy CPU, various synth engines, effects, cross platform compatibility, and many more features. After a brief demonstration of the tracker I will talk about my techniques for achieving a high development speed and maintaining the momentum. With this talk I hope to inspire attendees to build things from scratch and go onto their own explorative coding journeys. Christoph Schied established himself as a live experimental electronic music performer in the Seattle underground music scene under the moniker "Herr Shield". In his live performances he uses a hybrid hardware setup with his custom-written tracker. He has over a decade of experience as a professional graphics researcher and developer.

Wir bieten allen Interessierten die Möglichkeit, mit Elektronik zu basteln. Workshops und Vorträge zu verschiedenen Themen rund um Elektronik und Software sind willkommen. Von Arduino bis zu komplett selbst entwickelten High-End Schaltungen sind wir für alle kreativen Ideen offen. Wir haben auch Gruppen rund um das Nähen, Programmieren, Retro Computer. Wir treffen uns immer am Dienstag und am Freitag ab 18:00 Uhr. Egal ob Anfänger oder Profi – hier seid Ihr jederzeit Willkommen. Ihr könnt mit anderen fachsimpeln oder auch mit unserer Hilfe Eure ersten elektronischen Gehversuche starten. Wenn zeitgleich in den vorderen Räumen Workshops oder Vorträge stattfinden, kann hinten Werkstattbetrieb stattfinden.

(English below) \>\> der Event findet statt\, wenn sich bis 18:00 mindestens 4 Personen angemeldet haben\, sonst nicht << Worum es geht: "Kann ein Walfisch ein Wellensittich sein?" \~> Natürlich nicht, denn Säugetiere sind niemals Vögel. "Kann ein Fenster ein Getränk sein?" \~> Jeder weis, das ist unmöglich, denn Festkörper sind keine Flüssigkeiten. ABER: "Kann eine Demokratie eine Republik sein?" "Kann eine Vermutung eine Meinung sein?" "Ist etwas zu begreifen das Selbe wie etwas zu verstehen?" \~> Tja, jetzt wird's schwierig! Und es wird spannend... Nichts regt dermaßen zum nachdenken an wie dieses neue Gesellschaftsspiel. Die Spielregeln: 1. Jeder schreibt einen Begriff auf einen Zettel. 2. Die Zettel werden paarweise gezogen. 3. Per Beamer werfen wir die Bedeutung der zwei Wörter an die Wand. 4. jeder kann per Laptop (zur Not auch per Smartphone) die Bedeutung ergänzen / editieren, muss dafür ggf. Beispiele angeben warum etwas gleich sein können soll, oder nie gleich sein kann. 5. nach einer Zeit fällt niemandem mehr etwas ein. Unterschiede und Gemeinsamkeiten zwischen den beiden Begrifflichkeiten sind deutlich herausgearbeitet. Dann wird der Punktestand gezählt: (+1) Jeder verbliebene neue Beitrag in der Bedeutung ergibt einen Pluspunkt (-2) aber jeder wieder gelöschte neue Beitrag gibt zwei Minuspunkte. (+5) jede Verbesserung der bisherigen Bedeutung in Reclue ergibt plus 5 Pluspunkte Die Auffassungen aller Mitspieler werden viel klarer, erst recht wenn man häufig mitspielt. Ziel des Spiels ist nicht, dass irgendwer am meisten Punkte sammelt, sondern, dass alle zusammen überhaupt auf mehr als 50 Punkte kommen. Das Spiel funktioniert auch mehrsprachig. Man kann auch von Zuhause aus online mitmachen. Den Zugang können wir dann über die Kommentare hier organisieren. Bring deinen Laptop mit, dann wird es einfacher... Warum macht das Spiel klug? Schach trainiert das Konzentrationsvermögen. Aber es hat mit der Wirklichkeit nichts zu tun. Dieses Spiel hingegen schon, denn genau mitdenken zu können setzt voraus genau zu unterscheiden. Andernfalls assoziiert man das eine sprunghaft mit irgendetwas anderem. Aber ob die Assoziationskette notwendiger Weise der Fall ist, ist nicht klar - und andere Aspekte sind vll. viel wichtiger. Und dann irrt man in wirren Assoziationen, entscheidet wenig optimal, verliert Zeit, usw. Mit der Übung über dieses Spiel nicht mehr! Wer die Bedeutung der Wörter sauber ausdifferenziert wird immer klüger. \*\*\* english version \*\*\* "Can a whale be a parakeet?" \~> Of course not! "Can a window be a drink?" \~> Everyone knows that's impossible. "Can a democracy be a republic?" "Can a conjecture be an opinion?" "Is grasping something the same as understanding something?" \~> Well, now it gets tricky! And it gets exciting... Nothing stimulates thought quite like this new party game. The rules: 1. Everyone writes a term on a slip of paper. 2. The slips of paper are drawn in pairs. 3. We project the meaning of the two words onto the wall using a projector. 4. Everyone can add to/edit the meaning using a laptop or smartphone, and must provide examples of why something could be the same, or could never be the same. 5. After a while, no one can think of anything else. The differences and similarities between the two words are clearly highlighted. Then the score is tallied: (+1) Each new entry adding meaning earns one point. (-2) However, each deleted entry deducts two points. (+5) Each improvement on the existing meaning in Reclue earns five points. The understanding of all players becomes much clearer, especially with frequent play. The goal for the entire group is to reach at minimum 50 points. The game also works in multiple languages. You may join us from home using the internet. Comments in meetup-app will be used to organize that it works. The location (somewhere in Prenzlauer Berg) will be published the day when it takes place.

**From Projects to Products: Why Data Products Are Still Hard** A Data Products Book Launch & Practitioner Panel **About the event** This meetup marks the release of[ ](https://www.amazon.de/dp/B0GJDZNDMS?ref=cm_sw_r_ffobk_cso_cp_apin_dp_W685MDYH8P9CFTPVHV6S&ref_=cm_sw_r_ffobk_cso_cp_apin_dp_W685MDYH8P9CFTPVHV6S&social_share=cm_sw_r_ffobk_cso_cp_apin_dp_W685MDYH8P9CFTPVHV6S&bestFormat=true)**[Amy Raygada’s new book on Data Products](https://www.amazon.de/dp/B0GJDZNDMS?ref=cm_sw_r_ffobk_cso_cp_apin_dp_W685MDYH8P9CFTPVHV6S&ref_=cm_sw_r_ffobk_cso_cp_apin_dp_W685MDYH8P9CFTPVHV6S&social_share=cm_sw_r_ffobk_cso_cp_apin_dp_W685MDYH8P9CFTPVHV6S&bestFormat=true)**[ ](https://www.amazon.de/dp/B0GJDZNDMS?ref=cm_sw_r_ffobk_cso_cp_apin_dp_W685MDYH8P9CFTPVHV6S&ref_=cm_sw_r_ffobk_cso_cp_apin_dp_W685MDYH8P9CFTPVHV6S&social_share=cm_sw_r_ffobk_cso_cp_apin_dp_W685MDYH8P9CFTPVHV6S&bestFormat=true)and explores why, despite years of discussion, data products are still hard to implement in practice. Data products are not a new concept. For years, organisations have talked about treating data as a product — with clear ownership, well-defined interfaces, and measurable business value. And yet, many teams continue to struggle with fragmented dashboards, inconsistent metrics, and slow, reactive delivery. So why is this still so difficult? In this meetup, we’ll unpack why data products remain hard in practice — not because teams lack tools or frameworks, but because meaning, ownership, and operating models are often misunderstood or only partially implemented. Through in-depth practitioner talks and discussion, we’ll explore: * Why data initiatives often slip back into project mode * Where ownership breaks down across domains and platforms * How weak semantics and unclear definitions erode trust * What changes when data products are treated as long-lived products rather than delivery artefacts * Why AI and advanced analytics amplify these challenges instead of solving them The conversation is grounded in real delivery experience across engineering, architecture, and data strategy. It also features insights from Amy Raygada’s newly released book, which captures lessons learned from years of hands-on work helping organisations move from intent to execution. Expect practical perspectives, honest trade-offs, and an open discussion — not hype, not vendor pitches, and no one-size-fits-all answers. **About the speakers** **Amy Raygada** Principal Data & AI Strategist at Thoughtworks \| Author Amy Raygada is a Principal Data & AI Strategist at Thoughtworks, with over a decade of experience helping organisations design and govern data products that deliver real business impact. Her work spans data product strategy, governance, operating models, and AI readiness, with a strong focus on aligning technical capabilities with decision-making. This meetup marks the release of her new book on Data Products, bringing together lessons from years of real-world delivery across industries. **Kiran Prakash** Director, Data & AI at Thoughtworks Kiran Prakash is a Director in the Data & AI service line at Thoughtworks, working with organisations to design and scale data-driven systems. In his talk *“What We Talk About When We Talk About Data Products,”* Kiran presents a practical approach to designing, implementing, and governing data products. Drawing on real-world experience, he clarifies what data products are — and what they are not — and explores how teams can work backwards from use cases, apply adaptable implementation patterns, and use governance mechanisms such as fitness functions to keep data products aligned over time. **Carsten Fritsch** Principal Data Engineer at Thoughtworks Carsten Fritsch is a Principal Data Engineer at Thoughtworks in Berlin, with deep experience in data engineering, analytics architecture, and data modelling at scale. His work focuses on semantic layers, shared metrics, and the practical challenges of operationalising meaning across organisations. Carsten brings a grounded perspective on why semantics are foundational to trustworthy data products — especially as organisations move toward AI-driven use cases. **Format** * Each speaker will deliver a **25–30 minute talk**, followed by **Q&A** * Final **panel discussion** with all speakers * Open audience Q&A * Informal networking and book signing \-\-\-\-\-\- **Code of Conduct** We adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/) to ensure a welcoming and respectful environment for all participants.

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases.

**Photography 102: A Deeper Dive Into Photography** **Are you ready to dig deeper into photography? Then this intermediate photography course is perfect for expanding your knowledge of photography!** This intermediate photography class builds upon the foundational knowledge acquired in the Photography 101 class. It focuses on empowering students to move beyond automatic camera modes and take greater creative control over their images. This course uses an engaging and practical hands-on approach to reinforcing these newer and more advanced photographic concepts. **Through hands-on exercises and insightful lessons, you will learn:** * **Master More Advanced Camera Settings** * **Aperture and F-stops:** Understanding how aperture controls depth of field and using it to create blurry backgrounds (shallow depth of field) for portraits or sharp focus throughout a landscape (deep depth of field). * **Shutter Speed:** Learning to utilize shutter speed to freeze fast action or intentionally blur motion for artistic effects. * **ISO:** Exploring ISO settings for optimal image quality in different lighting conditions, understanding the trade-off between sensitivity and potential image noise/grain. * **Exposure Modes:** Beyond "Auto", understanding and utilizing manual (M), aperture-priority (A or Av), shutter-priority (S or Tv), and program (P) modes for specific shooting scenarios. * **White Balance:** Learn how to effectively set white balance controls to represent colors in varying lighting conditions properly. * **Metering and Exposure Compensation:** Understanding how the camera measures light and how to use exposure compensation to fine-tune exposure for desired results. * **On-Camera Flash Basics:** Gaining a basic understanding of when and how to use the built-in flash or external flash units effectively. * **Advanced Concepts and Techniques** * **Composition Beyond the Basics:** Looking at some more advanced composition concepts and taking a deeper look at the Elements of Design, learning to use space more effectively, controlling the elements of the scene that are drawing attention, and mastering visual weight. * **Lighting Beyond Natural Light:** Introduction to artificial lighting, such as off-camera flash, reflectors, and softboxes, to control and shape light for different effects. * **Basic Image Editing:** An introduction to photo editing software like Adobe Lightroom and Photoshop, covering essential tools for adjusting brightness, contrast, color, and sharpness. * **Developing a Personal Style:** Exploring ways to refine a unique artistic voice and create a consistent photographic style. **This class provides the next step in the path to becoming a more proficient and artistic photographer, allowing for more advanced usage of the camera system.** **Prerequisites:** * A camera (film, DSLR, or mirrorless) that has manual controls is required. Hands-on exercises make having the camera in class highly beneficial. You will need at least one lens to evaluate the results of control exercises. * You may attend this class in one of two ways: 1. With a class voucher provided by your retail camera store 2. Purchasing a seat in the class

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
