Hello PyData People! We are excited to announce our next event of 2026! This time, we will be hosted at Generali Italia’s Torre Generali in Milan for an evening dedicated to open data, data platform orchestration, and scalable data engineering. 📅 When: Thursday, May 19th, 2026 – 18:30–21:00 📍 Where: Torre Generali Italia, Milan ⚠️ Important: Spots are limited. Please keep your RSVP updated to allow others to participate if you can no longer attend. *** **🕒 Agenda** 18:30 – Doors open & check-in 19:00 – Talk 1: Democratizing Data: A deep dive into Eurostat Open Database – Simona Mazzarino 19:45 – Talk 2: Scaling Data Mesh Orchestration with Dagster: Platform-Driven DAGs without Platform Friction – Marco Santoni and Andrea Romeo 20:30 – Networking & Social Dinner *** **🎤 The Talks** **1️⃣ Democratizing Data: A deep dive into Eurostat Open Database** Speaker: Simona Mazzarino (Data Scientist @ Clearbox AI) In this talk, we explore how to turn open data into actionable insights. You will learn how to navigate Eurostat, the EU’s vast statistical database, and use Python tools to fetch and process data for research, AI, and real-world analysis. We will look at how to discover relevant datasets, work with Eurostat’s interface and APIs, and integrate public statistics into your workflows for visualizations, dashboards, and models. A guiding example will be the analysis of migration flows across European countries, from data discovery to a usable dataset for analytics or machine learning. About the Speaker: Simona Mazzarino is a Data Scientist at Clearbox AI. With a background in linguistics, semiotics, and artificial intelligence, she specializes in language technologies. She is an active volunteer in the Python Torino community, where she helps connect people interested in Python applications, and she also volunteers for PyCon Italia. *** **2️⃣ Scaling Data Mesh Orchestration with Dagster: Platform-Driven DAGs without Platform Friction** Speakers: Andrea Romeo, Platform Engineer @ TeamSystem Data Mesh promises scalability and autonomy, but orchestration often becomes the hidden bottleneck: as data products grow, cross-domain dependencies explode, DAGs become fragile, and upstream teams are forced to react to every new consumer. In this talk, we present a platform-designed orchestration solution built on top of Dagster that enables company-wide orchestration without coupling data products together. Instead of requiring data engineers to manually define DAGs or modify upstream pipelines, each data product simply declares its dependencies on upstream output ports. From these declarations, the platform automatically builds and maintains the global DAG behind the scenes, ensuring that upstream data products remain unaffected by new consumers, orchestration scales as the number of data products grows, and platform standards are enforced without slowing down teams. We’ll walk through: * the orchestration challenges we faced when adopting data mesh at scale * how Dagster was extended and shaped into a platform abstraction, not exposed directly to product teams * the Python-based design patterns used to dynamically generate and evolve DAGs * the resulting developer experience for data engineers building data products This session is a practical, production-tested story of how Python and Dagster can be used to enable scalable orchestration in a real data mesh implementation — without turning the platform team into a bottleneck. About the Speakers: Andrea Romeo is a Platform Engineer at TeamSystem, where he focuses on building and evolving the technical foundation behind data infrastructure. He works closely with development and data teams to design scalable, resilient platforms that support data-driven products and services, with a strong focus on backend, cloud technologies, and developer experience. *** See you there!

Sono proprietario di un bar e dispongo di un tavolo da biliardo semi-professionale. Sto creando un gruppo WhatsApp di giocatori amatoriali di biliardo americano pool/carambola, per la maggior parte debuttanti. Cerco persone disposte a unirsi al gruppo per giocare e divertirsi nel tempo libero, il pomeriggio oppure la sera in ogni giorno. Per stimolare l'impegno di ogni giocatore, abbiamo pattuito che il vincitore di ogni "mini-torneo" organizzato nei vari giorni giochi gratis e non paghi la tariffa di tempo per il periodo di gioco (un'ora di gioco costa 10€, ma viene di volta in volta frazionata in base al periodo di gioco effettivo). Il locale si trova in zona nord di Milano, stazione Greco-Pirelli, università Bicocca. Chiunque dovesse essere davvero interessato a partecipare e unirsi al mio gruppo, non esiti a contattarmi. Cerco persone serie e disposte solamente a divertirsi, senza puntare mazzette grazie mille. Antonio

Lake Moro is a natural gem of remarkable beauty. Nestled between the Sorline and Rodino hills and overlooked by Mount Pora and Mount Altissimo, it sits at just 381 meters above sea level. From a naturalistic point of view, the influence of the Mediterranean climate of Lake Iseo and the glacial climate of the Adamello makes Lake Moro one of the areas with the highest concentration of biodiversity in Europe. This unique condition also benefits local productions such as cheese, honey, and olive oil. **PROGRAM** 11:00 – Meeting point at G8 Wine Bar Café, Via Vittorio Veneto 20, 24060 Rogno (BG) 11:15 – Departure for Lake Moro Park 12:30 – Approximate arrival, free time, relaxing on the lakeshore, and lunch (packed lunch or independently arranged at local venues) 15:00 – Approximate return **Easy-Medium Level** – About 1h30 and 3.5 km each way, 250 m elevation gain. No special equipment or clothing required. Always bring some food and water, trekking shoes, a towel, and a swimsuit for a possible lakeside break. **Note 1:** Participants must reach the starting point independently (car, bus, train, etc.) or via carpooling by coordinating with other participants in the private Facebook and/or Telegram groups reserved for members (request access once you have your membership card). **Note 2:** The “I will attend” button on Meetup is not considered valid for us. Meetup is only used to publish the event and gauge interest. Once you become a member, please follow the instructions for the event’s *official* registration. **COSTS AND PARTICIPATION – MIN 7 PEOPLE, MAX 30** Event reserved for Gitup Enac members.
