Hallo liebe Java User Group Mitglieder! Diesmal haben wir Peter Kranz mit seinem interaktiven Talk zu den unterschiedlichen Java-Versionen zu Gast. Wir freuen uns euch zu sehen (virtuell oder vor Ort). * 18:00 Uhr: Einlass * 18:30 Uhr: Talk * ab 19:30: Ausklang des Abends Dank an [adesso](https://www.adesso.de/de/unternehmen/standorte/nuernberg.jsp) für Location, Bier und Pizza! \-\-\- Java entwickelt sich seit Version 9 im Halbjahresrhythmus weiter – mit Records, Pattern Matching, Virtual Threads und vielen weiteren Features. Doch wer hat schon die Zeit, 17 Releases im Detail zu verfolgen? Die Fülle an Neuerungen ist enorm, und je nach Projekt und Interesse sind ganz unterschiedliche Features relevant. Ein klassischer Vortrag kann hier nur einen starren Pfad durch die Feature-Landschaft bieten. Dieser Talk geht einen anderen Weg: als interaktiver Dungeon Crawler. Das Publikum entscheidet gemeinsam, welchen Themenkomplex es als Nächstes erkunden will – Moderne Sprach-Features, Concurrency, APIs, JVM-Tooling oder experimentelle Preview-Features. Jede Entscheidung führt tiefer in den Dungeon und schaltet neue Level frei. So entsteht bei jedem Vortrag ein einzigartiger Pfad durch die Java-Versionen 9 bis 26. Wie in einem echten Dungeon Crawler sammelt das Publikum dabei XP und wird am Ende einer Klasse zugeordnet – vom Warrior mit Fokus auf Performance bis zum Wizard der Sprach-Features. Ob Einsteiger:in oder erfahrene:r Entwickler:in: Jede Session liefert praxisnahe Einblicke in genau die Java-Features, die das Publikum am meisten interessieren. Kein Vortrag gleicht dem anderen – und der einzige Weg, alles zu sehen, ist wiederzukommen. \-\-\- 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!

**Hey art lovers,** It is a truth universally acknowledged, that a person in possession of a free Sunday morning must be in want of some fine art. I’m playing this one a bit "last minute," but honestly, some things are too good to miss. So I’ve decided to treat myself (and you!) to something truly special this Sunday. We are heading to the **Kodl Gallery** for their spectacular **pre-auction exhibition**. This is a rare chance to see world-class masterpieces from private collections before they go under the hammer and disappear into private homes again. It’s high-end art, but without the museum queues. The exhibition of free of charge. 📍 **The Plan:** * **The Gallery:** We’ll spend around 90mins soaking up the beauty of 19th and 20th-century art. * **The Secret Walk:** If we’re in the mood, we’ll take a leisurely stroll through the hidden, quiet backstreets of the Old Town—away from the tourist crowds. * **The Coffee Finale:** We’ll finish at a charming hidden coffee bar to chat about our favorite pieces over a caffeine fix and maybe something sweet. 💰 **Contribution:** **50 CZK** (A small contribution to help cover the Meetup platform fees). No pressure, just good vibes, great art, and even better company. It’s the perfect way to recharge before the new week kicks in. Can’t wait to see you there! 🖼️☕️✨ ***

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. 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.
