**✨ Migrating Legacy Languages to Python & MCP: Principles & Practice ✨** Ready to bridge the gap between decades-old legacy systems and the cutting-edge future of AI? Join us at Talent Garden Calabiana for a deep-dive technical night, co-hosted by Scops.ai and **TAG**. We'll tackle two major frontiers in modern engineering: the complex realities of rescuing business logic from legacy code to modern Python, and the hands-on mechanics of Model Context Protocol (MCP). Whether you're modernizing the past or building the future, this meetup is for you. **Agenda** * **18:30** Doors Open * **19:00** Introduction * **19:10** Talk: Migrating from legacy languages to Python with Federico Tomassetti * **19:50** Talk: Model Context Protocol: Principles and Practice with Luca Baggi * After the meetup we will organize a dinner close to the venue, anybody who wants to join is welcome! **Venue**: Talent Garden, Via Arcivescovo Calabiana 6 (M3 Lodi or Brenta) The event will be **recorded and streamed** on Python Milano Youtube channel (links will appear [here](https://www.youtube.com/@pythonmilano/streams) close to the event) **Migrating from legacy languages to Python** Python today has a vast ecosystem and an active community which makes it a great choice for many organizations. However, many companies still rely on critical software written decades ago in languages such as RPG, Visual Basic 6, or SAS. While these systems continue to work, they increasingly limit maintainability, hiring, integration, and long-term evolution. In this talk we want to discuss how the systems can be automatically migrated to Python. We will discuss the real technical and organizational challenges involved: understanding legacy semantics, preserving business logic, validating behavior, and managing incremental migration. The goal is to provide a clear overview of the techniques, trade-offs, and feasibility boundaries involved in translating legacy codebases into modern Python systems. The attendees will get a realistic understanding of what is possible today, when Python is a good target, and how to reason about migration projects without underestimating their complexity. **Federico Tomassetti, Language Engineering Architect @ Strumenta** Federico Tomassetti is the founder of Strumenta, a company specialized in Language Engineering. At Strumenta he builds Domain Specific Languages, editors, parsers, compilers, and interpreters. In other words languages and tooling to help professionals to work betterm. After getting his PhD he has worked in Italy, Germany, Ireland, and France. He worked for small companies and large ones like TripAdvisor and Groupon. **Model Context Protocol: Principles and Practice** Large‑language‑model agents are only as useful as the context and tools they can reach. Anthropic’s Model Context Protocol (MCP) proposes a universal, bidirectional interface that turns every external system—SQL databases, Slack, Git, web browsers, even your local file‑system—into first‑class “context providers.” In just 30 minutes we’ll step from high‑level buzzwords to hands‑on engineering details: How MCP’s JSON‑RPC message format, streaming channels, and version‑negotiation work under the hood. Why per‑tool sandboxing via isolated client processes hardens security (and what happens when an LLM tries rm ‑rf /). Techniques for hierarchical context retrieval that stretch a model’s effective window beyond token limits. Real‑world patterns for accessing multiple tools—Postgres, Slack, GitHub—and plugging MCP into GenAI applications. Expect code snippets and lessons from early adoption. You’ll leave ready to wire your own services into any MCP‑aware model and level‑up your GenAI applications—without the N×M integration nightmare. **Luca Baggi, AI Engineer @ xtream** Luca is an AI Engineer in xtream (now part of TeamSystem). He is a active member to the Python and PyData communities in Europe, and an open source contributor. ✋ **Please use your real Name and Surname to register, we cannot assure you will be able to access the venue if not.** \*\* If you have a last minute issue please remember to cancel the RSVP.\*\* \*\* Thanks for your cooperation\*\*

Il BookClub **The Reading Riot** si ritrova per parlare di *Il Signore delle Mosche* di **William Golding**, **Premio Nobel per la Letteratura**. Il romanzo racconta la storia di un gruppo di ragazzi rimasti isolati su un’isola deserta dopo un incidente aereo. Senza regole né adulti, il tentativo di autogestione lascia presto spazio a dinamiche di potere, paura e violenza, mettendo in discussione l’idea stessa di civiltà. Un classico che interroga ancora oggi sul rapporto tra individuo e gruppo, autorità, responsabilità e natura umana. L’incontro del BookClub è informale e basato sul **dibattito sui temi principali del libro**, partendo dalle impressioni personali di chi partecipa. Sarà una conversazione aperta, in cui ognuno potrà intervenire con il proprio punto di vista, in un clima intimo e rilassato. **Quando e dove** **Mercoledì 4 marzo** **Ore 19:00** **Viale Misurata 9, Milano** E' richiesta consumazione obbligatoria nel locale (no minimo di spesa). **Posti limitati** Per mantenere il gruppo piccolo e favorire lo scambio, i posti sono **limitati.** Una volta raggiunto il limite, verrà attivata una **lista d’attesa**. ⏳ **Importante** Se dopo l’iscrizione non riesci più a partecipare, ti chiediamo di cancellare la prenotazione entro il giorno prima, così da lasciare spazio a chi è in attesa. Porta il libro, il tuo entusiasmo e le tue impressioni — non vediamo l’ora di iniziare! Contatti IG: @thereadingriot_

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

Meeting Room 2b, Main Library Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen). Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. We desirere to cultivate a space where all questions are welcome and all members are treated with compassion and respect. All backgrounds are welcome.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
