Herzlich Willkommen zum WordPress Meetup Berlin! Auch im Jahr 2026 treffen wir uns weiterhin am letzten Mittwoch des Monats. Wir versuchen, abwechselnd Themen für Anwender\*innen und Developers behandeln. **Programm** 19:00 \| Einlass 19:15 \| Thema: wird noch gesucht 20:15 \| "Flohmarkt" Jede\*r kann kurz ein Gesuch oder Angebot in wenigen Sätzen pitchen. Bitte achtet darauf, dass es nicht zu kommerziell wird. 20:30 \| Happiness Bar\, freies Networking & Gespräche\. Bei Fragen oder Problemen mit WordPress könnt ihr uns gerne ansprechen und wir helfen euch mit eurem Problem. Das nennen wir "Happiness Bar". **Teilnahme** Die Teilnahme ist kostenlos. Essen und Getränke können wir leider nicht bereitstellen. Es gibt einen Snack/Getränke-Automaten und einen Kaffee-Automaten in der Bibliothek. Ihr könnt euch auch gerne etwas mitbringen und im Meeting-Raum essen. In der Umgebung gibt es einige Bäckereien, Spätis und Imbisse. Wichtig ist nur, dass wir den Raum wieder sauber hinterlassen. Falls ihr euch angemeldet habt und es doch nicht schaffen solltet, meldet euch bitte ab, damit wir einen Überblick über die Teilnehmerzahl behalten. **Barrierefreiheit** Die Location ist barrierefrei für Rollstühle. Falls ihr Unterstützung bei der Teilnahme oder Anforderungen an die Barrierefreiheit habt, schreibt uns gerne eine Nachricht. **Code of Conduct** Als WordPress Meetup verpflichten wir uns den Code of Conduct (sprich: unsere "Verhaltensregeln") einzuhalten:[ https://wpmeetup-berlin.de/regeln/](https://wpmeetup-berlin.de/regeln/) **Weitere Details und Infos** WPMeetup-Berlin Website: [https://wpmeetup-berlin.de/](https://wpmeetup-berlin.de/) Facebook-Gruppe "WordPress Berlin Brandenburg": [https://www.facebook.com/groups/331013360390412/](https://www.facebook.com/groups/331013360390412/) Twitter Account @wp_berlin: [https://twitter.com/wp_berlin](https://twitter.com/wp_berlin) #WPBerlin **Location & Raumsponsor** Ein großer Dank geht an die Bezirksbibliothek Pablo Neruda, dass sie uns den Raum zur Verfügung stellen. [https://www.berlin.de/stadtbibliothek-friedrichshain-kreuzberg/bibliotheken/bezirkszentralbibliothek-pablo-neruda/](https://www.berlin.de/stadtbibliothek-friedrichshain-kreuzberg/bibliotheken/bezirkszentralbibliothek-pablo-neruda/) **English speaking Attendees** \*Notice for our English speaking attendees: We are a German group and therefore most of our meetups and talks are held in German. However, many of our attendees are able to understand English well enough to respond to your questions. Which means: if you understand but don't necessarily speak German, that should be perfectly fine.

Welcome to the PyData Berlin May 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: Text2SQL in the Wild — Agentic Workflows & Semantic Models on Customer Data** **Abstract**: Translating a business user's natural language question into a reliable SQL query has huge value for business analysts, but doing it accurately at scale, on messy enterprise data, for complex queries, is incredibly difficult. This talk walks through a production Text2SQL system built on four pillars: semantic models built on customer data, RAG-based semantic search, an agentic verification and correction loop for building the SQL, and an evaluation framework for the entire process. Raw schema information is not enough for text2sql to work. Rather, thorough documentation including business metrics, synonyms, and qualified example queries, are required. We'll cover how to automate this documentation pipeline by mining query logs, generating descriptions with LLMs, and organizing everything into a knowledge graph and vector search index. From there, we'll dive into the agentic flow that takes a user question and iteratively generates, validates, and fixes SQL against a live database. The agentic framework analyses syntax errors and execution results to help it fix the SQL. Participants will leave with practical takeaways on RAG architecture for structured data, agentic retry patterns, and how to think about evaluation for Text2SQL systems in production. **Speaker**: Oren Matar **Bio**: Oren Matar is a principal data scientist and algorithms developer, with a background in social sciences and Bayesian methods. He specializes in NLP and time series forecasting, as well as agentic methods for data retrieval and processing. **Talk 2: Interpreting and Communicating Statistical Models** **Abstract**: Extracting actionable insights from complex statistical models remains a challenge, as raw coefficients are often uninterpretable due to nonlinearity, interactions, or hierarchical structures. This talk introduces a unified framework for model interpretation based on the principles of the Marginal Effects project ([https://marginaleffects.com/](https://marginaleffects.com/)). We move away from internal model parameters toward quantities of interest, such as marginal effects and adjusted predictions that translate statistical output into the "natural language" of the data. We will demonstrate these concepts in Python using the Bambi interpret module, showcasing a seamless workflow for interpreting Bayesian models built on PyMC. The audience will learn how to use the four primary interpretative pillars: Predictions, Comparisons, Slopes, and Marginal Means to compute average marginal effects and visualize conditional relationships. By the end of this session, you will be equipped to turn sophisticated GLMs and multi-level models into clear, rigorous narratives that are easily communicated to stakeholders. **Speaker**: Juan Orduz **Bio**: Juan is a Mathematician (Ph.D. Humboldt Universität zu Berlin) and Principal Data Scientist at PyMC Labs. He is interested in interdisciplinary applications of mathematical methods. In particular, time series analysis, Bayesian methods, and causal inference. **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.

In the previous meetup, we discussed a difficult question: **Will AI replace Scrum Masters and Agile Coaches?** This session builds on that conversation. Instead of focusing on what might disappear, we’ll focus on: **What will become more valuable.** 🧠 **What you’ll learn** We’ll explore the shift from: * Why facilitation and process knowledge are no longer enough * The shift from team-level focus to system-level thinking * How organizational design becomes a key capability * What skills will make you stand out in the coming years Grounded in Org Topologies™, we’ll look at: * Why many roles operate in **output-driven, incomplete setups** * The shift toward **outcome-oriented, complete mandates** * Why organizational design becomes a **core capability** * How AI amplifies this shift rather than causing it 🔑 **Core idea** The future is not about becoming a better Scrum Master. It’s about becoming someone who can: * see the organization as a system * identify structural constraints * redesign how work, learning, and decision-making happen 🎤 **Format** * \~30 min talk * \~30 min Q&A and discussion * \~30+ min Networking 👥 **Who this is for** * Scrum Masters & Agile Coaches seeking their next evolution * People struggling to create impact in their current setup * Leaders interested in system-level change * Anyone thinking about their next career step 💡 **Why join** Many people feel that “something is changing.” This session helps you **name the shift** — and position yourself within it. Btw: This meetup prepares the ground for a special session with the author of *10xOrg* in June.

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** https://youtube.com/live/BltmWMH1zG0?feature=share
