Dear all, we’re back with the PyData meetups, focused as always on sharing best practice, methodologies, analysis, machine learning systems, .., with the open-source projects of the [NumFOCUS](https://numfocus.org/sponsored-projects) program — but not only! We’ll meet **#InPresence on Thursday, June 18 at 7:00 PM**. We’ll be hosted by [Anda Venice Hostel](https://www.andavenice.com/) in the Medusa Room and, for those who cannot join us, it will also be on [YouTube](https://www.youtube.com/watch?v=I2P_IKlS3V0) in **#streaming**. 👥 We’ll have two interesting sessions one in Italian 🇮🇹 and one in English 🇬🇧: 🗣 [Fabio Lamanna](www.fabiolamanna.it), one of *PyData Venice* founders, will present an analysis of the real impact of "Bologna **#City30**", the 30 km/h limit, using **#FloatingCarData** (**#FCD**) with **#QGIS** and #Python to compare pre/post driving speeds and measure how much the city respects the new limit. 🗣 [Claudio Giancaterino](https://www.linkedin.com/in/claudiods/) will show a **#MultiAgent** system that turns car damage photos into an insurance claim assessment in minutes, where an Orchestrator coordinates a Vision Agent (**#GPT-5.2**), OEM/Aftermarket Cost Estimation Agents (**#Perplexity**), and a Shop Finder Agent, each running a transparent **#ReAct** reasoning loop to return damage severity, comparative repair costs, and recommended shops. And afterwards\, for those who want\, we’ll stay there for \( 🍸 \| 🍺 \) & \( 🍕 \| 🍔 \) and **#networking** until late ‼️ 📽 And if you’d like to share ideas, projects, topics, or propose yourself as the next speaker, here’s the usual [Google form](https://forms.gle/rVMWxFnodHaNb9ab9) or [Sessionize](https://sessionize.com/pydata-venice-2025-12-18) !

🍻 **Join Us for Tech Startups on the Terrace - Milan Edition!** 🍻 Hey there! 🌟 We have found a new location that suits out networking needs! Allora, we'd love for you to join us for our next edition of *Tech Startups in the Terrace*. The event is scheduled for **6 PM local Italian time**. The platform does not allow us to change the time zone, so we can only create events in GMT. Thus, you will see the invitation for 7 PM, but you definitely want to come earlier, since the place will be closed from 9-9:30 PM. It's a relaxed and refreshing evening at the **Porta Romana**, in a lovely **coworking space Open by Joivy**, and run by Volodymyr. We have been running for 3.5 years in London, and we are excited to now run our monthly events in Milan as well, welcoming new folks to the community. Whether you're a tech founder, an enthusiast, a budding entrepreneur, or simply curious about the tech scene, you'll fit right in. This isn't about panels or pitching, just good old-fashioned networking with like-minded people over a drink on a Thursday evening. **House Rules:** * Find Volodymyr to introduce yourself so we can welcome you properly. The place owners know we are coming, so you should be able to find us easily. * No hard selling or heavy pitching. This is a chill, friendly after-work get-together. * Not drinking? No worries! You're more than welcome to come hang out and enjoy the conversation. Mark your calendar and come down for some fun tech talk. See you there!

Hallo liebe Java User Group Mitglieder! Diesmal haben wir zwei Bonner Kollegen zu Gast: * Martin Stoller: **Backend-Performance in Hochlast-Systemen: Lösungsansätze aus dem Data Engineering** * Andreas Monschau: **Zehn goldene Regeln, um dein Softwareprojekt zuverlässig zu ruinieren** Wir freuen uns euch zu sehen (virtuell oder vor Ort). Dank an [codecentric](https://www.codecentric.de/standorte/nuernberg) für Location, Bier und Pizza! ================= Viele Hochlast-Systeme beginnen als kleine, unscheinbare Prototypen - gebaut mit bewährten Mitteln wie relationalen Datenbanken, objektorientierter Business-Logik und klassischen Request-Response-Architekturen. Doch was passiert, wenn diese Systeme plötzlich nicht mehr Tausende, sondern Millionen von Requests bedienen oder Terabytes an Daten verarbeiten müssen? In der Praxis zeigt sich häufig: Klassische Optimierungen wie Caching, horizontale Skalierung oder effizientere Algorithmen stoßen irgendwann an ihre Grenzen, weil sie innerhalb desselben Paradigmas bleiben. Dieser Vortrag zeigt, warum echte Skalierbarkeit oft ein Umdenken erfordert. Anhand eines durchgehenden Praxisbeispiels wird schrittweise demonstriert, wie sich ein System von einer latenzoptimierten Request-Response-Architektur hin zu einem durchsatzoptimierten, analytischen System entwickelt. Dabei werden zentrale Konzepte aus dem Data Engineering greifbar gemacht - darunter Precomputation, Batch Processing, deklarative Verarbeitung und Denormalisierung - und in den Kontext klassischer Backend-Entwicklung eingeordnet. Die Teilnehmenden lernen, typische Grenzen traditioneller Architekturen zu erkennen und erhalten ein alternatives Denkmodell, um High-Throughput-Systeme gezielt und nachhaltig zu skalieren. ================= Softwareprojekte sind chaotisch, anstrengend und voller Überraschungen. Und ganz ehrlich: So soll es auch bleiben. Ordnung würde ja nur den Spaß verderben. Trotzdem gibt es immer wieder Menschen, die glauben, man könnte Projekte wirklich zu Erfolg führen… unglaublich, oder? Damit dir so etwas nicht passiert, zeige ich dir in diesem Vortrag, wie du ein Softwareprojekt in 10 einfachen Schritten zuverlässig an die Wand fährst. Die „goldenen Anti-Pattern für maximalen Projektschaden“ entstammen jedoch nicht meiner Fantasie, nein, sie werden in der Realität täglich mit beeindruckender Konsequenz praktiziert. Und das Beste: Sie wirken nachhaltig. Manche dieser Muster entfalten ihre volle Zerstörungskraft erst Monate später. Nachdem du alle Regeln kennengelernt hast, kannst du selbst entscheiden: Möchtest du sie weiterhin anwenden, oder vielleicht doch etwas verändern? Solltest du allerdings inspiriert sein, eines dieser Anti-Pattern künftig noch konsequenter zu leben… dann sollten wir uns nach dem Talk dringend unterhalten. ================= Dein Vortrag bei der Java Usergroup Nürnberg! Hast du dich in letzter Zeit in deinem Projekt oder privat mit einem interessanten Thema beschäftigt? Vermutlich ist das nicht nur für dich selbst interessant! Hast du Lust, selber einmal einen Vortrag bei der Java-Usergroup Nürnberg zu halten? Wir sind nicht nur auf Java-Themen fokussiert, sondern beschäftigen uns gern mit und um alles über Software Entwicklung und IT. Wir wollen bei der JUG nicht nur bekannten Speaker\*innen eine Plattform geben und die neuesten State-of-the-Art Technologien vorstellen. Wir freuen uns auch besonders, wenn wir Themen aus unserem technologischen (Arbeits-)alltag Raum geben zu können. Melde dich gerne bei uns, wenn du dazu Lust hast, wir geben wenn gewünscht gerne auch Hilfestellung bei der Vorbereitung!

## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge. This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow. Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided! Parking: Plenty of free spaces available on-site. ###

**Abstract:** Motivated by the challenges of detecting extremely rare failures in sophisticated circuit design specifications, we study the problem of efficiently identifying multiple disjoint regions of interest (ROIs) — regions of a continuous, high-dimensional parameter space where a complex, expensive-to-evaluate target function falls below or above a pre-specified threshold. We reframe this problem as a Bayesian sequential decision-making problem and, more broadly, as an instance of strategic agent behavior in continuous spaces: an agent that must allocate a hard evaluation budget intelligently, updating its belief about the unknown function after each observation and choosing the next query to maximize coverage of all disjoint failure regions rather than convergence to a single optimum. This is a *hybrid* event. To attend online, join us on Zoom here at 6pm: [https://iit-edu.zoom.us/j/89379230295?pwd=NdETyE5sdYuSrvsrBZXSBFkUESBVkg.1](https://iit-edu.zoom.us/j/89379230295?pwd=NdETyE5sdYuSrvsrBZXSBFkUESBVkg.1) Meeting ID: 893 7923 0295 Passcode: 5t5WYn **Sponsor**: Grainger will provide the meeting site, as well as snacks for the onsite participants. * **Address:** 222 W Merchandise Mart Plaza, 18th Floor, Chicago, IL 60654 * **Grainger's Overview:** W.W. Grainger, Inc., is a leading broadline distributor with over $17 billion in revenue.

We are bringing Microsoft Build sessions to Columbus Ohio! The Central Ohio Azure Meetup and Central Ohio .NET Developer's Group (CONDG) are coming together to bring some of the labs and breakouts from Microsoft Build to your backyard. In this free, 1 day event, you are going to Build stuff with us! And yes, there will be free food. Please RSVP via [Microsoft Build //localhost:columbus | Microsoft Reactor](https://developer.microsoft.com/en-us/reactor/events/27247/).

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

We are going to build together with all the CLIs! E will be doing it at Columbus Code and Coffee Agenda --- Hosted By James Power, Organizer Pete Gordon, Organizer Just a Software Guy in the age of the Internet.
