**RSVP on the [343 Labs Website](https://343labs.de/events/ableton-user-group-berlin-4/) to reserve your seat!** Berlin Ableton User Group is back! This meetup is open to producers, songwriters, DJs, and musicians of all types and proficiency levels who use Ableton and are looking to exchange ideas, network, meet like-minded producers, and learn new tips and tricks from our presenters and fellow participants. This month, 343 Labs instructor Matthew Martinez will look at optimizing low-end for the dance floor. Ever struggled to get your kick and bass to balance, or wondered how to get you low frequencies to compete side-by-side with other tracks in the club? This masterclass will look at workflows for getting bass that bumps on big speakers. **About the artist:** Matthew Martinez is a producer, DJ, and educator with nearly a decade of teaching experience and over 20 years of musicianship. Born in the United States and now based in Berlin, Matthew continues to inspire the next generation of electronic music producers as both an artist and educator.

Welcome to the PyData Berlin February meetup! We would like to welcome you all starting from 18:00. There will be food and drinks. The talks begin around 18.30 and the doors will close at 18:45. **Make sure to arrive on time!** Please provide your first and last name for the registration because this is required for the venue's entry policy. If you cannot attend, please cancel your spot so others are able to join as the space is limited. **Host**: **GetYourGuide** is excited to welcome you to this month's version of PyData. \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* The Lineup for the evening **Talk 1: How Data (Science) is Transforming Professional Sports** **Abstract**: From Moneyball's linear regression revolution to AlphaGo's Move 37, data science has fundamentally reshaped how we understand and play sports. This talk explores three key dimensions of this transformation: first, how analytics revolutionized scouting and training—from the Oakland Athletics' 20-game winning streak to Liverpool FC ending their 30-year championship drought through data-driven player selection. Second, how machine learning and real-time tracking systems have changed gameplay itself, making the mid-range jump shot obsolete in basketball and revealing chess strategies that had eluded grandmasters for thousands of years. Finally, we'll examine the darker consequences, including how ML-powered microbetting has transformed sports gambling into a $149 billion industry that resembles slot machines more than traditional wagering. This talk offers insights spanning baseball, soccer, basketball, chess, and Go - demonstrating how data science doesn't just optimize existing strategies, it fundamentally questions the assumptions entire sports were built upon. **Speaker**: Kaan Isik **Bio**: Kaan Isik is a Data Scientist at GetYourGuide where he works on the Activity Ranking team. As a member of this team, he focuses on developing and optimizing the learn-to-rank deep learning model that powers real-time activity recommendations for millions of travelers worldwide. His work directly impacts how users discover activities across GetYourGuide's platform, making their travel planning more personalized and efficient. **Talk 2: Can Foundation Models outperform classic ML on structured data? Hands-on experience with TabPFN** **Abstract**: LLMs excel at generalising over text data, but cannot reliably predict outcomes from spreadsheets and databases, which drive most critical decisions across medicine, finance, science and virtually all industries. In this talk, we will showcase how TabPFN, Tabular Foundation Model developed by Berlin-based Prior Labs, successfully generalises over structured data problems, beating classic ML with win rates ranging from 100% to 87%. **Speaker**: Diana Kriuchkova **Bio**: Diana is leading Product at Prior Labs. She is a part of the team developing TabPFN, a foundational model for tasks on structured data. TabPFN was published in the 2025 issue of Nature journal, and has shown to beat classic ML methods like XGBoost in >80% of cases. Diana's former background is in machine learning, and she spent last years leading product at developer-focused startups in Berlin. **Lightning talks** There will be slots for 2-3 Lightning Talks (3-5 Minutes for each) between the two main talks. Kindly let us know if you would like to present something :) \*\*\* NumFOCUS **Code of Conduct** THE SHORT VERSION Be kind to others. Do not insult or put down others. Behave professionally.

**\>\> Please note that the event's location will be sent to you once you RSVP <<** Hey, I’m Annabelle, and I’m a recovering bulimic. I struggled with bulimia for 15 years, and I’ve always wished there was a space where I could talk about it openly, without judgment, without shame, just honesty, support, and people who *get it*. People who are also on this journey. People who want to heal and figure out who they are beyond bulimia. So, I decided to create that space. **What is this group about** * A space where you can talk about your **binge eating or bulimia** without feeling judged. * A space to reconnect with yourself — the *you* that exists beyond the eating disorder. * A space for support and real connection with people who are going through (or have been through) the same thing. * A place to share your wins *and* your hard days, and be met with encouragement and support. **What to expect** * Journaling prompts, discussions, games, readings from ED-related literature, meditations, and more. * Deeper conversations — not just about the ED, but about who you are underneath it all. **Who is this for?** * **This group is open to women who are struggling with binge eating or bulimia and *want to recover.*** **What this *isn't*** * This is not therapy. I’m not a therapist and won’t be giving advice on nutrition, exercise, or anything medical. * This is not a place to talk about numbers, weight, calories, or daily food habits. * This is not a place to give unsolicited advice. If someone asks for support, great — but advice will only be shared if it’s asked for. * This is *definitely* not a space that promotes or glorifies eating disorders. **A bit about me** I’m 33, I live in Berlin, and I have a very eclectic taste in music — but I always come back to Nightwish. When I’m not reading memoirs or self-help books, you’ll usually find me looking for a new café around the city or walking in the forest or a park. Some of my favorite podcasts include *The Rich Roll Podcast*, *How I Built This*, *We Can Do Hard Things*, and *The School of Greatness.* I’m a certified life coach, and I’m passionate about guiding people to unlock their own truth and remove the mental blocks that hold them back from pursuing their purpose. Right now, I’m writing a weekly blog called *Life Beyond Bulimia*, which you can find on my Substack. **Before you sign up** The location of this group will be revealed once you RSVP. While the space is kindly provided to us for free, we are asked to contribute 1€ per person per meeting (including myself). There's an online version of this group, to see the dates and register, visit [this link. ](https://www.eventbrite.com/e/1820313028269?aff=oddtdtcreator) To make sure everyone is heard, the meetings will be limited to 10 people at a time. Can’t wait to meet you! Until then, know that you are stronger than you think. 🌹 Annabelle

Join us on **February 11** as we explore modernizing React apps (compiler, useEffectEvent & more) and dive into real-time collaboration powered by a triplestore without a traditional backend. **🗣 Call for Proposals** Have an idea or story to share? Submit your talk proposal through our [CFP form](https://docs.google.com/forms/d/e/1FAIpQLSfbG_BEJJYuAtVL5vhMMnWTpQbYHzGM8kmlqaJ790-Lgqv0fA/viewform) and take the stage at one of our upcoming meetups! **🤝 Organized by** This event made possible thanks to the support from[ React Summit](https://reactsummit.com/) and[ JSNation](https://jsnation.com/) organizers –[ GitNation](https://portal.gitnation.org/). **🤝 Sponsored by** Huge thanks to our friends from Superhuman! Superhuman (formerly Grammarly) is the AI productivity platform on a mission to unlock the superhuman potential in everyone. The Superhuman suite of apps and agents brings AI wherever people work, integrating with over 1 million applications and websites. The company’s products include Grammarly’s writing assistance, Coda’s collaborative workspaces, Mail’s inbox management, and Go, the proactive AI assistant that understands context and delivers help automatically. Superhuman’s global team brings together over 1,500 people across Europe and North America.

And more* *In this talk we’ll take a demo React app that’s full of effects, memoization and “old school” patterns, and modernize it step by step.* **➡️ A Triplestore-Powered BaaS: Real-Time Collaboration Without the Backend** *Backend-as-a-Service platforms promise simplicity, but often lock developers into complex APIs authorization rules. What if your frontend could directly manage data, authorization, and collaboration - without domain-specific backend code?* *In this talk, Oliver shares how he built a triplestore-based BaaS to power real-time collaboration in his side project MonsterWriter, and how the approach grew into an independent open-source project. We’ll see how LinkedRecords.com enables fine-grained authorization, simplifies real-time collaboration, and supports a Bring Your Own Backend model that gives organizations more control over their data and vendor relationships. It is also shown how global state management becomes a lot easier in React apps.* **➡️ Building Cross-Platform Agentic UI at Superhuman** *Recently, Superhuman (formerly Grammarly) launched Superhuman Go, an AI assistant that works alongside you on every platform. To build it, we needed a scalable solution that supports an unlimited number of agents that dynamically shapes the user interface and looks similar across all supported desktop and mobile platforms. Join me to find out how we discovered solutions for this innovative new product.* **—** **👍 Code of Conduct** By registering for this event you agree to comply with our[ CoC](https://portal.gitnation.org/coc) **📩 Contact** events@gitnation.org [https://twitter.com/ReactSummit](https://twitter.com/ReactSummit) [https://bsky.app/profile/reactsummit.gitnation.org](https://bsky.app/profile/reactsummit.gitnation.org) [http://youtube.com/ReactConferences](http://youtube.com/ReactConferences)

**A place to meet sound, without maps** Facilitated by **Vesti Gium (they/them)** Everyone enters as they are. No score. No threshold of skill. We follow the room, moment by moment— listening, nudging, letting the music find itself. A breath, a shoelace, a laugh, a footstep— each carries weight. Silence is welcomed; noise is celebrated. There are no wrong directions here. We practise a listening that reaches outward and inward: to ourselves, to one another, to the space we shape together. That is where the music begins. * 🌀 Bring a voice, an object, an instrument, a movement—or nothing at all. * ✨ **Priority given to FLINTA folks and people with migration backgrounds.** * 🎧 No experience needed. Curiosity is enough. * 📍 Berlin – \[theodorstraße 5,12099] * 🗓 Every Wednesday 17: 30 * 📬 DM or email **[vestigium.impro@gmail.com](mailto:vestigium.impro@gmail.com)** to join Come make sound—come be heard.
