Software Architecture

**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.

Learning Czech can be hard and demotivating, especially when studying alone. **This meetup is a shared study session where we come together to stay focused, motivated, and make progress — each in our own way.** This is a co-learning / co-studying session, not a class. There is no teacher, no lesson, and no study material provided. Everyone comes with their own resources and studies independently, in a shared environment. 🧠 **How it works** • We all bring our own material: • textbooks • homework from a Czech course • Duolingo or other apps • reading practice • vocabulary review, etc. • We mainly work individually • We are free to: • ask questions • help each other • share tips and resources • No teacher, no formal structure, no pressure 👥 **Who is it for?** • Czech learners of all levels • Non-Czech speakers (expats, internationals) • Czech native speakers are welcome if they want to help, but this is not a language exchange ⏱ **Practical info** • Location: Cafedu 12, Škrétova 490, 120 00 Praha 2 (Metro A and C, Muzeum station) • Duration: 2 hours, or less or more, as you want • Day & time: Monday, 18:00 • Group size: small group for now • Free event — please support the café by ordering a drink ☕ If you’re learning Czech and lack motivation when studying alone, come join us — let’s find it together 🙂

Der König ist tot, es lebe der König. So könnte man das neue Projekt der **Green Software Foundation** umschreiben. Nach Jahren der Entwicklung bei *Amadeus* (führender Anbieter von IT-Lösungen für die Tourismusbranche) wurde das Projekt in Teilen open sourced und der GSF übergeben. Ziel von **Carmen** (Carbon Measurement Engine) ist es alle Emissionen über eine Vielzahl von Anwendungen zu erfassen. Somit tritt es faktisch die Nachfolge von „*Cloud Carbon Footprint*“ an und nutzt auch dessen Kennzahlen. Im Kern setzt Carmen auf das Impact Framework auf und bringt es in die reale Anwendung. Zu Gast haben wir **Florent Morel**, der Kopf hinter Carmen. Er wird uns mit einem Deep Dive in das Tooling einführen und zeigt uns, wie wir Carmen konkret einsetzen können.

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!

We will provide a fun and interesting activity to encourage simple English conversation. It may be a game, an interesting topic, or whatever. We promise to keep the evening relaxed and give you a chance to practice your English. • What to bring Just you. • Important to know We are hosted by Do Slova Praha. As a church, we want to help our community in practical ways. We may hand out information to other events that our church does, but do not worry... this is not a religious event. Just come to practice English :) [https://www.doslovapraha.cz/](https://www.doslovapraha.cz/)

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!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
