Back in August, we explored how Design Thinking can help us uncover and validate the right problems. But even when we agree on what to build, things often go wrong, not because of bad solutions, but because we don’t fully understand what the problem actually means in practice. In this session, we’ll build on that idea and focus on the next step: turning vague ideas into something concrete, shared, and testable. Using Example Mapping - a lightweight technique from Behaviour-Driven Development (BDD) - we’ll work in small groups to: * Break down a feature into rules, examples, and questions * Surface hidden assumptions and edge cases * Align on what the behaviour of a system should actually look like If the previous session was about finding the right problem, this one is about understanding it well enough to build it right. 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!

In diesem Kurs beschäftigen wir uns mit verschiedenen Texten aus unterschiedlichen Bereichen. Das können u.a. kurze Geschichten, Gedichte, Zeitungsartikel, Kolumnen oder Videos sein. Immer sind es Themen, die uns gefallen, die wir besonders interessant, wichtig oder manchmal auch richtig schlecht finden. Gemeinsam versuchen wir die Position der Autor*in, den Stil und die Argumentationsstruktur zu verstehen. Dazu diskutieren wir über das, was wir verstehen, welche Meinung wir zu dem Thema haben oder welche Fragen offen bleiben.
Gerne könnt ihr uns auch Themenvorschläge mitbringen oder zuschicken.
Der Kurs richtet sich an interessierte Menschen mit einem B2-Niveau (oder so ähnlich), die Lust haben sich weiter mit der deutschen Sprache zu beschäftigen und ihren Wortschatz zu erweitern.
Die Termine sind sporadisch.

How to the find the FOODFACTORY Cube Berlin (Effe&Gold):** Washingtonpl. 3, 10557 Berlin https://g.page/foodfactorycubeberlin?share Our meeting spot is inside right next to Effe&Gold.

How to the find the Kan'Koa restaurant:** Oranienburger Str. 17, 10178 Berlin https://maps.app.goo.gl/DL5ifV3XzDSkJeAq6 This Asian restaurant has a cozy atmosphere which gives the opportunity to have meaningful conversations. They offer a good mix of Japanese and Vietnamese cuisine. I would recommend this to vegetarians as well as vegans. *Who is this meetup for:* 1\. Asians who want to practice German and/or English\. 2\. German speaking individuals who are studying \(preferably\) Japanese\, Korean\, Mandarin or Cantonese\. 3\. Anyone who is interested in cultural exchange and wants to socialize\. *What you can expect:* 1\. A professionally organized meetup that can adapt to any changes given the current situation\. 2\. A Walk & Talk to break the ice\. 3\. A collaborating venue where you can further socialize with other members\. *** Whenever you attend a meetup, the most common as well as first question you get is: "Where are you from?" You probably heard this question a million times. Well, at least I did. From my own experience of attending over 200 international meetups in various countries such as Germany, Japan, Australia and Thailand, I can tell you that asking for the name is a better approach. “A person’s name is to that person, the sweetest, most important sound in any language.” - Dale Carnegie If you really want to connect with like-minded people you should remember their name, but you don't have to remember every persons name you've talked you. Be picky about that, don't be me who can somehow remember everyones name easily. Don't tell yourself sth. like "I'm bad at remembering names." It's all about developing the habit of asking for a name and keep the conversation going on. Furthermore, you want to learn German or any other language. Learning the local language is crucial to connect with the locals and developing a true friendship. This can be accomplished with immersion. My goal is to inspire you to go out of your comfort zone and improve yourself each time you join this meetup.

Für Mitglieder von Text Collective Berlin ist die Teilnahme an dieser Veranstaltung kostenlos. Nicht-Mitglieder werden um eine Spende von zehn Euro gebeten. [https://textcollective.de/ticket](https://textcollective.de/ticket) Es handelt sich um einen moderierten Workshop. Kreative Schreibübung mit anschließender Diskussion zum Erfahrungsaustausch, Inspiration und Motivation zu sammeln. Ein Raum für alle, die kreativ schreiben möchten – egal ob du gerade erst anfängst oder schon länger schreibst. **Jeden zweiten Samstag des Monats von 14:30 Uhr bis 16:30 Uhr in Charlottenburg (Haus am Mierendorffplatz).** **Was dich erwartet:** In unseren Treffen arbeiten wir mit abwechslungsreichen Schreibimpulsen, die neue Perspektiven eröffnen und spielerisches Experimentieren ermöglichen. Du schreibst direkt vor Ort, teilst deine Texte mit der Gruppe (freiwillig!) und erhältst konstruktives Feedback. Die Atmosphäre ist offen und unterstützend. Hier darf ein Text noch unfertig sein, eine Idee noch roh, ein Gedanke noch unausgereift. In dieser Atmosphäre gegenseitiger Wertschätzung entsteht der Mut, sich auszuprobieren und die eigene Stimme zu entdecken. Wir lesen einander vor, geben Rückmeldung, ermutigen uns gegenseitig und praktizieren das Zuhören. **Über Text Collective Berlin:** Wir sind eine kreative Schreibcommunity, die regelmäßige Workshops und Lesungen organisiert. 2025 erschien unsere erste Anthologie "Begegnung zwischen Welten" mit Texten aus der Schreibwerkstatt.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
