**PyBerlin: March event** **Sponsor**: Spiced Academy **Location:** Spiced Academy, Ritterstrasse 12-14, 10969 Berlin, Germany **Agenda:** 6:30 pm – Doors open: snacks, drinks, networking 6:55 pm - Welcome from PyBerlin 7:00 pm - Welcome from the sponsor - Spiced Academy **7:10 pm** – **What Actually Changes Customer Behavior? Causal Thinking Across Attribution, Segmentation, and Growth // Dr. Maryam Ramezani-Bartsch** Customer data is often used to explain what happened: attribution assigns credit, segmentation groups users, and dashboards track performance. Yet marketers and business leaders still struggle with a more fundamental question: what actually changed because of our actions? This talk introduces causal thinking as a practical way to interpret customer data across attribution, segmentation, and growth. It shows why correlation-based metrics can be misleading and how counterfactuals and incrementality help teams ask better questions when they look at results. A concrete email campaign example illustrates how causal uplift modeling separates customers who would have purchased anyway from those whose behavior truly changed. The goal is to help data scientists, marketers, and decision-makers move from reading metrics to reasoning about incremental impact and to make better decisions because of it. Speaker's bio: Dr. Maryam Ramezani-bartsch is a data and analytic leader with over 20 years of global experience building and scaling customer analytics and data science teams. She has led the development of customer data, marketing measurement and targeting capabilities for global brands such as adidas, Sky, Delivery Hero, and Zalando, helping embed customer-centric, data-driven decision making across organizations. Her work focuses on building customer data models, causal analytics, experimentation, and developing teams that turn insights into sustained business impact. **7:40 pm - Python 3.14 & 3.15 news! // Hugo van Kemenade** The release manager will share some of the exciting things in the newest versions of your favourite programming languages. **7:50 pm - break** **8:10 pm** – **Your Next On-Call Engineer could run Locally //** **Anthony Alaribe** What if your next on-call engineer wasn't a person, but a Python agent running on your machine? Inspired by the explosion of local agents like OpenClaw, this talk explores what happens when we point agentic workflows at the systems we monitor. We'll walk through the checklist most engineers actually run during on-call: checking dashboards, tailing logs, correlating errors with recent deploys, and then explore how to build a custom Python agent that automates these checks using tools like LangGraph, OpenTelemetry, and the Anthropic SDK. You'll leave with a working starting point and a new way to think about what agentic AI can do beyond chatbots. Speaker's bio: Anthony has spent over a decade building software at companies like Opera, and DeliveryHero. He has faced his fair share of dealing with unreliability software and breaking changes in APIs, including losing over $2m in orders to such an incident, amongst other war stories. Say hi when you him. He loves conversations about AI, databases, and programming languages. **8:40 pm – What makes XGBoost so powerful // Rakibur Rahman** XGBoost (Extreme Gradient Boosting) is one of the most influential machine learning algorithms of the last decade, originally developed by Tianqi Chen. It has become the default choice for structured (tabular) data problems, widely used in both industry and data science competitions on platforms like Kaggle. This talk explains why XGBoost works so well, from both a mathematical and practical engineering perspective. Speakers bio: Rakibur Rahman, PhD is Senior Coach of Data Science & AI at Neuefische/Spiced Academy, Berlin, with 20+ years of analytical problem solving and data analysis experience. With a background in Theoretical Physics, he is keen to apply cutting-edge machine learning algorithms and AI tools for driving positive business impact. Endowed with the ability to present complex ideas in simple pedagogical form, he delivered 50+ professional talks at the international level. His global experience includes working/studying in the USA, Germany, Italy, Belgium and Bangladesh. 9:10 pm - closing This event will be only in-person.

Liebe Meetup-Community, schön, dass du hier bist. Suchst du gerade nach einem neuen Funken für dein Leben? Pass auf: Diese Veranstaltung wird dich vielleicht nicht nur unterhalten und inspirieren – sie könnte deine Sicht auf die Dinge (und damit dein Leben) grundlegend verändern. Wenn du bereit bist, lies weiter. **Findest du dich in einer der folgenden Situationen wieder?** * **Frust trotz Erfolg:** Du (und vielleicht dein Partner) hast eigentlich alles „richtig“ gemacht – Studium, Karriere, gutes Gehalt. Aber durch die Inflation und steigende Kosten fühlt es sich nicht mehr selbstverständlich an, eine hohe Lebensqualität zu führen (beim Einkaufen, beim Urlaub buchen oder beim Eigenheimkauf). Hinzu kommen Bedenken über die Altersvorsorge aufgrund des aktuellen Rentensystems. * **Was nun nach den ersten Schritten?** Du hast dich schon an Aktien, ETFs, Krypto, Immobilien usw. herangetraut, aber der Weg zu deinem Traumleben sieht noch unendlich weit oder ungreifbar aus. * **„Selbst“ und „ständig“:** Du hast den Schritt in die Selbstständigkeit gewagt, fühlst dich aber gestresst – sei es wegen der Finanzen, dem Zeitmangel für dich und deine Familie oder beidem. **Stell dir vor, du gehst nach diesem Abend so nach Hause:** * **Antrieb:** Du erkennst, dass dein eigentlicher Traum, den du vor Jahren in die Ecke geschoben hast, doch möglich ist. * **Klarheit:** Du weißt jetzt, was dein nächster Schritt ist – und du hast richtig Lust, ihn zu gehen! * **Freude:** Du stehst am nächsten Tag nicht mehr aus Pflichtgefühl auf, sondern aus echter Freude. **Was wir machen:** Wir treffen uns in lockerer Runde und spielen das **[Cashflow-Spiel von Robert Kiyosaki](https://en.wikipedia.org/wiki/Cashflow_101)**. Keine Theorie, sondern Spiel bzw. Simulation pur. Wir probieren auf dem Brett Sachen aus, die man im echten Leben vielleicht gar nicht sieht oder sich nicht traut – und lernen dabei extrem viel über unser eigenes Geldverhalten. Wir lachen viel, tauschen uns ehrlich aus und kommen als Gruppe weiter. **Der Plan:** * **18:30 Uhr:** Ankommen, Drink schnappen, kurz quatschen. * **19:00 Uhr:** Spielstart (ca. 90 Min.). * **Danach:** Offene Runde. Wir reden Tacheles – über Aktien, Krypto, Immobilien und deine persönlichen Erfahrungen. Steig ein – spielerisch, ehrlich und vielleicht ist das hier der Startschuss für dein neues Leben. Beste Grüße und bis dann, Shuying ========================================== **Wer wir sind:** Wir sind eine vielfältige Gruppe von Menschen, die entdeckt haben, dass strategisches Aktienhandeln für jeden zugänglich ist. Unser Ziel ist es, unsere gemeinsame Erfahrung zu teilen und Anfänger im Aktienhandel zu inspirieren, sich sinnvoll und emotionsfrei zu investieren. Wir glauben fest an das Konzept des gegenseitigen Lernens – indem wir dir helfen, lernen auch wir von dir, und schaffen so eine Win-Win-Situation für alle. **Was wir glauben:** * Erfolgreiches Aktienhandeln ist keine exklusive Domäne für Finanzexperten. * Das Verstehen von Aktien und das Treffen informierter Anlageentscheidungen ist für jeden erreichbar. * Du benötigst keinen Abschluss in Betriebswirtschaft, um die Prinzipien der Wertanlage zu verstehen. * Technische Aktienanalyse ist nicht nur für Finanzprofis gedacht; es ist eine Fähigkeit, die du erlernen kannst. **Über die Gründerin dieser Meetup Gruppe:** Shuying hat Mitte 2023 selbst ihren Weg zur Anlegerin gefunden – von der Frustration und Überforderung zur begeisterten Aktieninvestorin, nachdem sie die Grundlagen der Chartanalyse gelernt hatte. Inspiriert durch diese Erfahrung gründete sie diese Meetup-Gruppe, um andere auf ihrem Weg zu mehr Selbstvertrauen, Klarheit und finanzieller Freiheit zu unterstützen.

To build truly autonomous systems, we need to move beyond local setups. This session is about **creating a stable, containerized foundation** that allows us to abstract from infrastructure in future sprints. **The Plan:** We will containerize a basic agent and deploy it to Google Cloud Run. This creates a repeatable environment where our results can be hosted, scaled, and accessed via stable endpoints. **This is a "Lab" session. We will:** * **Show & Tell:** Briefly discuss the move from local scripts to containerized services. * **Hands-on Building:** Containerize a Python/FastAPI/JS/TS agent using Docker. * **Cloud Deployment:** Push our images to the cloud and go live on GCP. **The Format** We run our sessions like an anthology series: **Every meetup is a standalone sprint.** While we often build on previous results, each session provides a complete experience and remains fully accessible to first-time attendees. This is a high-density micro-meetup limited to 6 seats. **What you'll build** By the end of the session, you'll have: 1. **A Dockerized Agent:** A portable container containing your agent logic. 2. **A Cloud Deployment:** Your agent running on GCP Cloud Run with a public URL. 3. **Foundation for the Future:** An environment ready for Inter-Agent Communication (Sprint #5). **Schedule (Saturday, 10:00 - 13:00 CET)** * **10:00:** Quick round of introductions. * **10:15:** Intro session: Docker, Containerization, and GCP Basics. * **10:30:** **Build time:** Hands-on experimentation and Cloud Deployment. * **12:00:** Live demos + technical teardown. * **12:45:** Wrap-up + takeaways. **Prerequisites** * **Google Account:** Essential for GCP access and project setup. * **Laptop with dev setup:** Docker installed and working. * **Access to an LLM API:** (Gemini, Claude, OpenAI, etc.). * **Mindset:** This is a lab for engineers, not a tutorial. We learn by building, breaking, and iterating. **Logistics** * **Location:** We meet at my office in the Grunewald area near Martin-Luther-Krankenhaus. The exact address will be shared privately with attendees to maintain privacy. * **Capacity:** Limited to 6 seats.

**Last meetup before the summer!** This time, we are trying a new format — **EM Kata Unconference**. ​**Two tracks:** AI in software delivery and fundamentals of tech leadership.

**Rust Berlin on location 🏳️‍🌈** is a new, informal in-person Rust meetup group in Berlin. We are a interactive meetup format interested in mob coding, deep diving and problem solving together. We build toy projects, share experiences, discuss technology and learn new cool stuff. And you are welcome to join! No matter if you are writing Rust production code every day, if you already contribute to Open Source projects or want to start doing so, if you use Rust in hobby projects or if you are just curious what the hype and buzz is all about, you are very welcome! To coordinate and plan activities, please join our **[Rust Berlin on location 🏳️‍🌈](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)**[ Zulip chat](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)! **Planned programme** Being an informal meetup, we are open to anything between just meet and talk, explore nerd snipes and rabbit holes, mob code together, plan and build fun projects, tinker with electronics, and presentations with Q&A. With the [introduction](https://berline.rs/2026/04/01/berlin-talks.html) of the new [Rust Berlin Talks](https://berline.rs/about#rust-berlin-talks) meetup series, **[Rust Berlin on location 🏳️‍🌈](https://berline.rs/about#rust-berlin-on-location)** strengthens its focus on social community experience, the exchange of knowledge, ideas and perspectives, and the joy of spontaneity. This time, we will try a new interactive discussion format: Jonas will introduce the topic of *The Job Market and AI* with an impulse presentation, then open up a moderated discussion with all participants. Let’s see where this hot topic leads us! If someone brings other cool stuff, questions or problems, then let us dedicate the second half of the meetup time to that! Anyone is invited to bring their projects and questions, show something, ask something, or explore a topic together. The best conversations and deepest rabbit holes can emerge out of seemingly nowhere. **Projected upcoming meetups** We schedule regular meetups on Thursday evening every four weeks, using the slot between the Berlin Rust Hack and Learn online meetup (every two weeks), and the Rust Nuremberg online meetup (every four weeks). 19 March 2026 is our twelfth meeting. Our next projected meetings are going to occur on the following dates: * 16 Apr 2026 * 14 May 2026 (tentative, public holiday) * 11 Jun 2026 * 9 Jul 2026 * 6 Aug 2026 * 3 Sep 2026 **Location** Our meetup location is the new shared office community space of Ferrous Systems, Slint and KDAB in Berlin Mitte, for up to 25 people. We are expecting to use this space as our default location for the time being, with the IN-Berlin e.V. community space in Moabit as backup. Regardless, as our group might eventually outgrow the locations' size limit, we are low-key looking for bigger locations. If you know a fitting location, then please let us know in our Signal group! Another workable way might be to split the meetup into smaller, interest-specific sub-groups instead. As the no-show rate on Meetup.com is rather high, consider showing up even if you are on the waiting list. We can't promise that there is any space left, but usually there is. So give it a shot! **Accessibility** The location has an elevator and a wheelchair accessible bathroom. Please note that the bathroom is two floors down from the meetup space. On our quest for a bigger location, we are going to pay special attention to accessibility. **Community** We aim to create a safe place for everyone and adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/). Inclusivity is very important to us. If you are curious about Rust, but unsure if you are welcome to join: Yes, yes you are. Please come to the meetup! If you have special needs, please get in contact, we will try to accommodate you as best we can. We are part of [https://berline.rs/](https://berline.rs/) and like to hang out in the Berlin Rust Hack and Learn online meetup's [Matrix channel](https://matrix.to/#/!xycQxSjSAvEezkyztA:chat.berline.rs). You are very welcome to join!

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA

Join **Daclaud** at **The Arcane Foundry** for an evening that introduces newcomers and enthusiasts alike to the timeless craft of **tabletop wargaming** and **miniature painting**. My own journey began with a fascination for fantasy — knights in armor, grim and hardened warriors, and monstrous creatures locked in epic battle. That passion led me to **Dungeons & Dragons**, where I painted my first **Basic Heroes set** and felt the spark that comes from bringing a character to life in miniature form. Not long after, I discovered **Warhammer Fantasy** and **Warhammer 40,000**, and I was hooked. The vision of vast armies clashing across the table — each unit meticulously painted, each story unfolding through dice and imagination — became my creative obsession. During this event, we’ll explore the **origins of wargaming**, from its early military simulations to the richly detailed worlds of modern tabletop battle systems. You’ll learn how to **build and customize your own armies**, paint your first figures, and experience the joy of turning strategy and storytelling into a hands-on art form. Whether you’re drawn by the lore, the hobby, or the thrill of commanding miniature legions, this introduction will open the gates to a world that has captivated hobbyists for generations. **🎨 RSVP today and join us at The Arcane Foundry — where every brushstroke and battle tells a story.**
