Some friends of PyData are organising the following event, and we think it would be great to share it with the community. Pixels2GenAI is an exhibition by software developers creating computer art. We have used equations, algorithms, and AI models to generate images and installations. The artists explore the space between hand-programmed images, the aesthetics of mathematical rules, and AI as an art-making tool. Works by the following artists will be on display: * Burak Kağan Yılmazer * Sara Maras * Alexander Hendorf * Hansu Kim * Maris Niewenhuis * Ewa Rother

!!! Note the corrected meeting spot, which for some reason keeps getting changed in the event: [https://maps.app.goo.gl/L8SuKJxoLLa8hXCdA](https://maps.app.goo.gl/L8SuKJxoLLa8hXCdA) \-\-\- **Mandarin Learner Meetup in Berlin! *(Free resources below)*** **Learning Mandarin is like trying to tame a** 🐲**.** It can feel frustrating, but you’re not alone. **[WeHanzi](wehanzi.com)** is here to support! **[WeHanzi](wehanzi.com)** is an independently built iOS app created by Ben and Gina. We've turned the entire learning experience into ***Comprehensible Input* through both simplified and traditional manga** with support for **Zhuyin**, **Pinyin**, **flashcards**, **audio**, **direct translation**, an integrated dictionary. We also specifically design region-specific language to reflect real-life usage in both **mainland Chinese Mandarin** and **Taiwanese Mandarin**, allowing you to naturally compare and explore the differences between the two, so you don’t end up saying something that makes perfect sense in Beijing, but gets you funny looks in Taipei 😏. Now, together with our good friend Matthias from **[Gemeinsam Chinesisch & Deutsch lernen](https://www.meetup.com/gemeinsam-mandarin-chinesisch-und-deutsch-lernen/events/308204343/?eventOrigin=group_upcoming_events),** we’re inviting you to our very first **in-person Mandarin Learner Meetup in Berlin** together! All levels are welcome, from beginners to advanced learners. Just come hang out, share your stories, laugh at our tone mistakes! As a community, we can learn from each other and turn Mandarin into a piece of cake! 🍰 **Come and join us!** 📱 App: [Wehanzi.com](https://wehanzi.com/) 📸 Free bite-sized resources: [Instagram](https://www.instagram.com/wehanzi/) 📚 More free tools: [wehanzi.app/menu](https://wehanzi.app/menu) **📍ABOUT THE MEETING SPOT** Please note that we will meet HERE, on the 3 wooden tree benches slightly left of the main entrance gate of Tempelhofer Feld: [https://maps.app.goo.gl/L8SuKJxoLLa8hXCdA](https://maps.app.goo.gl/L8SuKJxoLLa8hXCdA) We'll meet at the meeting spot first and then - depending on the weather - decide as a group to either walk around Tempelhofer Feld or go to a closeby restaurant to warm up and chat.

Für Mitglieder von Text Collective Berlin ist die Teilnahme an dieser Veranstaltung kostenlos. Nicht-Mitglieder werden um einen Teilnahmebeitrag von zehn Euro gebeten. Hier buchen: [https://textcollective.de/ticket](https://textcollective.de/ticket) Es handelt sich um einen moderierten Workshop. Bei mehr als 20 Teilnehmenden teilen wir die Gruppe mit zwei Moderator\*innen auf! 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 vierten Samstag des Monats von 14:30 Uhr bis 16:30 Uhr in Kreuzberg, Oranienstr. 72, nahe U-Bhf Moritzplatz.** **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.

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. Some of us journal, some write novels, some do academic writing, many people come without a project in mind and see where the inspiration flow takes them. This is a space to simply show up and write, a safe place to be yourself and to release all your layers onto the paper. There’s no set topic, no feedback circle, and no pressure. Just warm people, a calm atmosphere, and time dedicated to yourself. 🗓️ **Agenda:** * 14:30 - 15:00 **→** 30 min arriving, optional socialising (arrive early, meet other writers) * 15:00 - 16:00 **→** 1 hour of silent writing (headphones welcome, focus encouraged) * 16:00–16:30 **→** 30 mins break + optional chat or solo time (stay and chat or go celebrate the rest of your Saturday) * 16:30–17:30 → 1 more hour of silent writing (for those staying) * 17:30–18:00 → 30 mins of chat, and leaving 🎒 **Bring:** * Something to write with (laptop, notebook, phone, typewriter… anything goes) * Something to drink (there is no cafeteria, unfortunately) * Your current project or a blank page * Yourself, exactly as you are **👉 Responsibility:** * Our location is limited; thus, I am kindly asking you to RSVP only if you are willing to attend. **📍Location:** * We meet at **Heinrich Schulz Library in Charlottenburg**. In the library, go look for the Gruppenraum; I will be waiting for you there. Any trouble finding the room, I will come to meet you outside. * 🚇 U7 **Richard-Wagner-Platz** * 🚌 M45 Bus **U Richard-Wagner-Platz** **About me:** Hi, my name is Anastasia. 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. Let's write together!

​Wir laden dich ein, Tango zu entdecken oder bei uns zu üben, wenn Du schon tanzt - egal, ob Du führen, folgen oder nur eine Rolle ausprobieren willst. Warum TANGO? Tango ist eine soziale und körperliche Aktivität, die uns aus der digitalen Welt in die physische und sinnliche Welt zurückführt wie Yoga oder Tai-Chi, was hilft, die Verbindung zum Boden, zu uns selbst und zum Anderen spüren - für gute Laune, Selbstwirksamkeit, digitales Detox. Und: Musik durch Bewegung auszudrücken, mag fast jede/r. 1️⃣ 18.30 ✨ Technik-Deep-Dive: Wir starten mit Basics. Für Anfänger oder Tänzer, die ihre Technik polieren wollen. 2️⃣ 19:30 Praktika zum Üben für Altes und Neues, mit und ohne Partner. Musik ohne Cortinas. 3️⃣ 21:00 Circular Moves: Ideen, für Bewegungen, wie sie für das soziale Tanzen mit wenig Platz möglich sind. ✨ Open Role, solo oder mit Partner/in: Wir empfehlen zu wechseln, aber das ist keine Verpflichtung. Wohlfühlen steht im Vordergrund: Einladungen können abgelehnt werden: Hi Google, was ist ein Cabeceo? DE / EN We invite you to discover Tango, whether you want to lead, follow, or simply try out a new role. If you already dance, come by to practice! We embrace the classic Practica spirit: a space to learn from one another. Tango is a social and physical activity that brings us back from the digital world into the physical and the sensory realm. Much like Yoga or Tai Chi, it focuses on our connection to the ground, to ourselves and to one another. And let's face it: expressing music through movement is something almost everyone loves. Your hosts are Davide, Nacho, Pietro and Rafa. ✨ ​Wir freuen uns über einen Beitrag zwischen 5 € und 25 €. Limonade, Bier, Wein sind vorhanden. ​Da unsere Türen nur einmal im Monat öffnen, geben wir gerne Tipps, wo ihr in der Zwischenzeit tanzen und üben könnt. Clase: Rafa Hosts: Davide, Nacho, Rafa

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.
