Let's talk Android! This month, we are at SumUp and are welcoming these amazing opportunities: **Android AI Workflows** - *Frank Tamre* I will share a practical, what i sue set of AI workflows I use in Android projects to ship faster without sacrificing code quality. This isn’t a “prompt engineering” talk; It’s a set of repeatable patterns that can integrate into Android engineering. **Crafting Idiomatic APIs with Kotlin and Compose** - *Ash Davies* In this talk, we’ll dive into the principles of idiomatic Kotlin and explore how they apply to designing Compose APIs. You’ll learn how to leverage Kotlin’s language features, from DSLs and inline functions to advanced type safety and composable conventions, to craft APIs that are a joy to use. By mastering these techniques, you can deliver APIs that not only “work” but truly feel like Kotlin. **Your Talk here** - *You* *{Insert your talk topic here}* Afterwards, we welcome you to stay and socialize (or sit in the corner listening) with or against our community. Happy Coding / Prompting / Designing / Leading / Working.

Get hands-on with Google Agent Development Kit (ADK), Google’s framework for building, evaluating, and deploying AI agents. You'll progressively learn to design advanced agents and train them to play the text-based adventure game “The Garden of the Forgotten Prompt”.

Join us for a hands-on workshop by Olena Kutsenko on Wednesday, February 25th from 5:30pm hosted by SPACE SHACK Coworking! **Venue:** **SPACE SHACK Coworking** Akazienstraße 3A, 10823 Berlin, Germany **Agenda:** * 5:30pm – 6:00pm: Welcome, Food/Drinks & Networking * 6:00pm - 8:30 pm: Workshop by Olena ** So that Olena has an idea of audience priorities, please fill in the [pre-workshop form](https://docs.google.com/forms/d/e/1FAIpQLSeJsBjgkL2EXvPtBScXtI5yAv6N9gFg64QmMajMUiMmaPllxQ/viewform?usp=sharing&ouid=117948459316244235775) when you can (no personal info is collected)** ** Speaker & Workshop Details:** Olena Kutsenko, Staff Developer Advocate, Confluent **Hands-on workshop: real-time flight data streaming, anomalies, predictions, and visualizations** **Workshop Overview** In this hands-on session, we'll build a real-time analytics pipeline using flight data and modern streaming tools — step by step, and without hand-waving. We'll start by streaming data into Apache Kafka using Confluent Cloud, process it with Apache Flink, and land it in Apache Iceberg using Tableflow. From there, we'll query the data with Trino and turn it into dashboards using Superset. Everything runs in a practical setup you can reproduce later, including Docker and cloud-managed services. Along the way, we'll also look at anomaly detection and simple predictions using built-in functions, so you can see how real-time insights can be added without building custom ML pipelines or complex models. This session is all about doing, not slides. You'll see how the pieces actually fit together, what decisions matter in practice (regions, credentials, formats), and how to go from streaming data to analytics in a way that scales. If you're curious about real-time analytics, Kafka + Flink in the cloud, or how streaming, analytics, and lightweight predictive use cases come together in the same pipeline, this workshop will give you a clear, working mental model — and code you can take home. No prior experience with Kafka, Flink, or Iceberg required! Just bring your curiosity and a laptop! **Technical Prerequisites:** To make sure you can get hands on during this workshop, please make sure the following are installed on your system (**Make sure your bring your laptops!)** **1\.

The school was founded in the middle of the 15th century by Iizasa Chōisai Ienao at the Katori Shrine (Katori jingū) and has become the origin of numerous other martial arts schools over the course of its almost 600-year history. The training consists of the continuous repetition of fixed sequences of movements (kata) and includes the use of classic Japanese weapons such as the sword (iai-jutsu, battō-jutsu, ken-jutsu, ryōtō-jutsu, kodachi-jutsu), the long staff (bō-jutsu), the lance (naginata-jutsu) and the spear (sō-jutsu), as well as unarmed disciplines, tactics and spiritual aspects. **The Katori Berlin dojo** is the only official shibu of Otake Nobutoshi-shihan’s dojo Shinbukan in Germany and fully dedicated to the transmission and study of one martial tradition: Tenshinshō-den Katori Shintō-ryū. Through these efforts we aim to contribute to the cultural preservation of this martial tradition. The dojo has one officially appointed shidosha. **Our sensei**: Sebastian Graetz has been active in martial arts since 1997. After almost 15 years of taekwondo in Berlin, he started with Katori Shintō-ryū in Asia in 2014. Since then, he has studied in Japan with Ōtake Risuke-shihan and Ōtake Nobutoshi-shihan, and in Vietnam with Malte Stokhof-shihandai. In 2023, he received his Menkyo license and permission to set up a training group in Berlin the following year.

The "classical" bookswap is simple: * We meet in a café and put the book(s) we brought down on the tables. * We browse and discuss the books with one another while sipping coffee or hot chocolate, or eating cake. * We write our names down on any books we’d like to take home (post-its and pens provided). * At the end of the evening, negotiate any books that are contended and take a new-to-you book home! Books/happiness shared are books/happiness multiplied! A Bookswap is 10 times better than a Book Club because you can talk about ALL the books instead of just one! This is a great way to give your books a new home and make room for new books: that book you feel guilty for not having read even though it's been sitting on your bedside table for the last 5 years, the book you liked but didn't love, the book you loved so much you want everyone to read it, the book you somehow own three copies of, that book you absolutely hated even though everyone else loves it, and so on. Moreover, you will meet fellow readers, get a new book or two, and several book recommendations. We’ve often had readers experience books they wouldn't normally buy and enjoy it. GROUP EXPECTATIONS for PLEASANT SWAPPING * Please bring a book! It's not that you bring one you take one, but do try your best to bring something. * Books stay on the tables, open for sharing, until you are ready to leave so that everyone can have a look. We are notably not first come first serve. Please wait until you are leaving to bag the book. * If two or more people want the only copy of a book, negotiate. Maybe one of you reads it first and then gives it to the others. Or perhaps they have found another book instead. Or leave it to fate and toss a coin. The best part: now you have found somebody whose taste you can really admire. In any case, please don't walk away with a book with several names on it without letting the others know. These negotiations are fun and easy, so don't shy away from a book because there's already a name on it, and feel free to put your name on as many books as you find interesting. It's not that you bring one you take one; you may take as many as you can negotiate. * Political discussions with consent: make sure the people you are talking to would like to have a political discussion with you. * Please respect this space as first and foremost a community for connecting readers over their love of books and reading, stories, and narratives of all sorts. Please be respectful of tastes and opinions. * If something is bothering you, please reach out to the organizers, and we'll do our best to resolve it. * Lastly, don't expect your book back. It will find a new home. If you love it, let it go. Major LANGUAGES (and genres) of this meetup: English, German, French, Spanish, Italian; Fiction, Non-Fiction, Serious Reading, Light Fun, “classics", Krimis, Booker winners, Sci-Fi, Fantasy, Self-Help and more. You never know who can read what languages, and there's no accounting for taste. We are a delightful and international group of readers. We look forward to swapping with you!

Register: [https://globalai.community/chapters/berlin/events/ai-memory-and-founders-night/](https://globalai.community/chapters/berlin/events/ai-memory-and-founders-night/) This edition of the **Global AI Berlin** meetup focuses on one of the most critical topics for modern AI systems: **AI Memory** and its role in shaping the next generation of intelligent applications. The event brings together founders, product leaders, and engineers to explore how memory is designed, structured, and operationalized in real-world AI systems. With contributions from teams at **Neo4j, Cognee, MemVerge, Riverty and more**, and the broader Berlin AI community, the discussions will cover practical approaches to building memory-enabled applications at production scale.

International Meetup for those who still like to follow the Peaceful teachings of Christ. We are free and curious humans, try to practice patience, kindness, humanity, etc, and have the freedom to read any book of the world, including the Gospels. Let's support each-other, upbuild faith, and find some like-minded friends in our community. (If you are a new believer, you are also welcome only if you have been practicing Christianity regularly for at least since last 3 years. )

Ciao a tutti! For our event we would like to meet you at 17:00 and have a beer all together, or other drinks. The goal of our first meeting is to get to know eachother and practice Italian and German. Please don’t be afraid that your language skills might not be sufficiently good or that you are a beginner. We understand that learning languages is a difficult and long journey. We don’t tolerate discrimination. We don't tolerate any aggressive or weird attitude. This has to be a Place of Comfort zone for everyone :) Please be respectful and kind with the others! PS: you can find us on the pool table area usually, if not just ask to the bar area for the reservation on the name "Claudio" A presto, bis bald Claudio Ich hoffe dass wir bald uns sehen!

Columbus libraries: [https://cml.bibliocommons.com/v2/record/S105C3262835](https://cml.bibliocommons.com/v2/record/S105C3262835) Location: [Knotty Pine Brewing](https://www.knottypinebrewing.net/) [Menu, scroll to the bottom](https://www.knottypinebrewing.net/menus-1) Book summary: Adunni is a fourteen-year-old Nigerian girl who knows what she wants: an education. This, her mother has told her, is the only way to get a "louding voice" -- the ability to speak for herself and decide her own future. But instead, Adunni's father sells her to be the third wife of a local man who is eager for her to bear him a son and heir. When Adunni runs away to the city, hoping to make a better life, she finds that the only other option before her is servitude to a wealthy family. As a yielding daughter, a subservient wife, and a powerless slave, Adunni is told, by words and deeds, that she is nothing. But while misfortunes might muffle her voice for a time, they cannot mute it. And when she realizes that she must stand up not only for herself, but for other girls, for the ones who came before her and were lost, and for the next girls, who will inevitably follow, she finds the resolve to speak, however she can--in a whisper, in song, in broken English--until she is heard
