🚀 Workshops: The Human-Digital Synthesis **Kultur\-Technik 2026 \| Women in Big Data Berlin** AI is no longer a future concept—it is already reshaping how we work, create, and make decisions. The real question is: **how do we use it intelligently?** *Kultur-Technik 2026:* *The Human–Digital Synthesis* draws from the European idea that technology is an extension of human culture.

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.

​Collaborative improv & storytelling for social media. This event is a collaboration between [Social Rising](https://luma.com/socialrising) & [Social Adventures](https://luma.com/socialadventures) and will be announced on both channels. ​Grab your camera, microphone(s), and other equipment you already have, (re-)start your CapCut subscription, and let's meet to create content. We'll meet outside in a park, which should allow us to both have enough space to create content with each other but also find other people to interact with (don't record without approval!). ​Important: If you don't want to be in front of the camera, then don't join. You don't have to have social media, though. ​After we meet, we first get to know each other and then create stories, improve them, record them for social media, edit them right there, and post them. ​What do you need? * ​Motivation, and ideas for stories for social media * ​A mobile phone or camera * ​All equipment you have at home for filming: External/bluetooth microphones, prop, ... * ​Editing software like CapCut or Filmora directly on your phone. ​​The event starts at 14:00 and lasts up to 2 hours. ​We'll meet at Tiergarten at the following spot: [https://maps.app.goo.gl/dzXw9NXMLAjBqBUE9](https://maps.app.goo.gl/dzXw9NXMLAjBqBUE9) ​The communication before, during and after the event happens in our Telegram group: [https://t.me/czc_berlin](https://t.me/czc_berlin?utm_source=luma).

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. Ask the barista/bartender if you can't find us.

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!\*\***

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.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
