**Je design proces mrtvý, nebo není?** AI umí postavit skoro cokoliv. O to víc záleží na tom, co jí zadáme. Discovery a výzkum dnes rozhodují víc než kdy dřív. Výzkum už nedělá jen výzkumník. Prototypy nevznikají ve Figmě, ale v kódu. Designéři commitují a shipují. A hranice mezi designem, researchem a engineeringem se stírá rychleji, než stíháme aktualizovat workflow. UX Monday 4. května je o tom, jak to vypadá v praxi, když přestanete ctít procesy ze setrvačnosti a začnete je přepisovat za pochodu. Dva pohledy, dvě perspektivy: 🎤[ ](https://www.linkedin.com/in/erikvanek/)**[Erik Vaněk](https://www.linkedin.com/in/erikvanek/)** – o tom, proč „design proces je mrtvý" je mýtus a co se naopak dramaticky mění. Konkrétní příklady z poslední doby: demokratizace researche, prototypování přímo v kódu, zkracování feedback loopů. Upřímně o tom, co funguje, co ne, kde jsou rizika a kde jsou lidi pořád nenahraditelní. 🎤 **[Anna Kutíková](https://www.linkedin.com/in/anna-kutikova/)** & **[Jiří Groh](https://www.linkedin.com/in/grohjiri/)** – o tom, jak v Oh-So přepnuli mindset celé agentury, umožnili designérům commitovat, shipovat a využívat AI engineering. Co to udělalo s rolemi, handoffem a hlavně se spoluprací s vývojem.

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!

It takes places in the lands of Solamnia, near the capital city Solanthus, on the world of Krynn. **BMG-DLEP-VOTU-02 Dragons of Future Past (Lvl 6 - 8) EPIC** The Chosen have outraced the Dragon Army to the Fount of Wisdom—a mysterious location that holds clues to finding the Genesis Shard. As the Chosen seek a way to unlock the Fount’s secrets, the Dragon Army arrives in the distance. The Chosen and their meager force must discover the way to the Shard while holding off the Dragon Army! **What is an EPIC?!** Dragons of Future Past is a D&D Epics™ adventure. As such, it is run interactively between multiple tables at the same event. In a multi-table event, Epic Headquarters (Epic HQ) is operated by one or more Epic Administrators (Epic Admins). Epic Admins ensure that all tables follow the same adventure flow, start and finish each part at the same time, perform any required calculations, and provide read-aloud text for all tables at once. During an Epic adventure, things may occur at one table that influence another. There may be NPCs or monsters, controlled by Epic Admins, which wander from table totable. There may also be chances for tables to enlist assistance from other tables. As such, all tables taking part in the event work together toward a common goal. When we host special events such as EPICs, all proceeds will go to a charity *(in this case, Dobry Andel)*. \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* **CAST IDENTIFY: WHAT IS ADVENTURERS LEAGUE?** Adventurers League (AL) is a D&D public play program - start the story at one table, and bring your character to the next part of the adventure at any AL table in the world! **New to D&D?** No problem!

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!
