Agile Project Management

**Um was geht es dieses mal?** Dieses Mal dreht sich alles um aktuelle Herausforderungen, Best Practices und Trends rund um IT-Sicherheit. Freut euch auf praxisnahe Einblicke, spannende Diskussionen und den Austausch mit Security-Expert:innen. **So leicht können Hacker Ihr Unternehmen über öffentliche Daten angreifen - Mehmet Avci (codecentric)** Jedes Unternehmen hinterlässt einen digitalen Fußabdruck – oft unbemerkt, aber öffentlich zugänglich. Genau diese frei verfügbaren Informationen machen sich Angreifer im Rahmen von Open Source Intelligence (OSINT) zunutze, um gezielte Angriffe vorzubereiten, ohne dabei technische Schutzmechanismen direkt angreifen zu müssen. In diesem Talk wird gezeigt, wie einfach es für Angreifer ist, Unternehmen allein auf Basis öffentlich verfügbarer Daten zu analysieren und zu kompromittieren. Nach einer Einführung in die Grundlagen von OSINT und die typischen Phasen eines OSINT‑Prozesses werden verschiedene Techniken vorgestellt und eingeordnet. Dazu gehören unter anderem Subdomain‑Enumeration, Google Dorking, die Auswertung von Unternehmensinformationen, Social‑Media‑Analysen, das Sammeln von E‑Mail‑Adressen sowie die Nutzung von Datenlecks und Breach‑Daten. Anhand praxisnaher Beispiele aus realen Szenarien wird verdeutlicht, wofür diese Techniken eingesetzt werden und wie Angreifer die gewonnenen Informationen miteinander kombinieren, um detaillierte Profile von Organisationen, Infrastrukturen und Mitarbeitenden zu erstellen. Der Vortrag schärft das Bewusstsein dafür, wie aus scheinbar harmlosen Einzeldaten ein ernstzunehmendes Sicherheitsrisiko entstehen kann – und warum OSINT ein zentraler Bestandteil moderner Angriffe ist. **This is fine - until it's not - Christian Uhsat (codecentric)** Was passiert, wenn was passiert? Erfahrungsberichte aus Digitaler Forensik und Incident Response im Kampf gegen Cybercrime, Ransomware und den allgemeinen Wahnsinn. **Hybrides Setup!** Wir freuen uns, euch bei uns in den Räumen der codecentric AG in Dortmund willkommen zu heißen. Vor Ort versorgen wir euch mit Snacks und Getränken und freuen uns gleichzeitig über interessante Diskussionen und einen guten Austausch. Für alle, die es nicht zu uns ins Office schaffen, werden wir das Meetup Hybrid durchführen. Der Stream beginnt ca. 10 Minuten später, damit wir vor Ort ausreichend Möglichkeit für persönliches Kennenlernen haben. Den Live-Stream findet ihr auf dem [YouTube-Channel ](https://www.youtube.com/@codecentricAG)der codecentric AG. **Wichtig - Absage bitte rechtzeitig:** Wir bestellen das Essen bereits 3 Tage vor dem Meetup. Falls ihr doch verhindert sein solltet, bitten wir euch um eine rechtzeitige Absage. Das ist wichtig, damit wir nicht unnötig Essen verschwenden müssen. Vielen Dank für euer Verständnis! **Anreise:** Per Zug: Vom Dortmunder HBF sind es ca. 10 Minuten zu Fuß. Mit dem Auto: Rund um das Office gibt es einige Parkflächen, dazu befinden sich in dem Parkhaus der Thier-Galerie weitere Parkplätze.

We are back with your monthly dose of PHPAmersfoort on the 12th of May. We are invited by the people of the Bitlair Hackerspace in Amersfoort, where Maarten Bode will show us how Pricore can be used as an open-source private package registry for Composer. 19:00 - Doors open 19:30 - **Manage private packages with Pricore** \- Maarten Bode 20:30 - Social **Manage private packages with Pricore** Private PHP-packages beheren klinkt simpel. Satis die vastloopt, tokens die rondslingeren, geen zicht op wie toegang heeft. In deze talk laat Maarten zien hoe Pricore als open-source Laravel-app private package management weer overzichtelijk maakt.

We are excited to announce our next Utrecht JUG meetup, on **May 12th** hosted by **JDriven**. It will be an evening packed with practical insights and real-world lessons from modern software development. Join us for a great mix of knowledge sharing, engaging talks, and of course food, drinks, and good conversations. We kick off the evening with food and drinks before diving into our first session, where **Susanne Pieterse** explores how Retrieval-Augmented Generation (RAG) can be applied in large-scale, real-world environments. Moving beyond demos, she’ll share hands-on experiences from modernizing legacy systems, covering challenges like document processing, access control, and keeping AI grounded in reliable data. After the break, **Jos Roseboom** takes the stage with a deep dive into performance pitfalls in JPA and related technologies. With practical examples and a touch of humor, this session uncovers how ORM abstractions can sometimes lead to unexpected slowdowns and how to detect and fix them before they impact your users. We’ll wrap up the evening with drinks, giving you plenty of time to connect with fellow developers, exchange ideas, and reflect on the sessions. Plus, don’t miss the chance to win a JetBrains license in our giveaway. Join us for an evening full of learning, inspiration, and great conversations. Please join us and RSVP! Because of the limited number of seats, please keep your RSVP up-to-date, so we can welcome someone else if you can't make it. *** ## Timeschedule 17:00 Doors open 17:45 Food & Drinks 18:30 RAG in the Wild: Real-World Lessons from Modernizing Legacy Systems by Susanne Pieterse 19:30 Break 19:45 When ORM Becomes OMG: Performance Pitfalls in JPA and Friends by Jos Roseboom 20:45 Drinks # Giveaway 1 JetBrains licence *** # Talks ## RAG in the Wild: Real-World Lessons from Modernizing Legacy Systems Enterprise and government document systems hold terabytes of valuable unstructured information, yet most still rely on keyword and metadata search with little semantic context. Retrieval-Augmented Generation (RAG) promises a breakthrough, but tutorials rarely prepare you for regulated, large-scale environments. In this talk, I’ll share lessons from building a RAG stack with Spring Boot, Elasticsearch, LangChain4j, Docker, and ActiveMQ, using both Azure OpenAI and Ollama. Expect concrete insights on document chunking, enforcing access control, and keeping LLMs grounded in facts — practical takeaways for anyone bringing RAG from demo to production. *** # When ORM Becomes OMG: Performance Pitfalls in JPA and Friends JPA makes database interaction feel almost magical—until your app grinds to a halt. In this talk, we’ll take a tour through the common (and not-so-common) performance pitfalls that turn object-relational mapping into an object-relational mess. From data loading surprises to connection mismanagement, we’ll explore real-world issues using a sample app: the FunFactStore, where fun facts are sold, but bugs are free. We’ll dig into how seemingly harmless libraries can sometimes do more harm than good, and how tooling can help you spot trouble before your users do. Whether you’re using Spring Data JPA, navigating tricky transaction boundaries, or just wondering why things suddenly got slow, this session offers practical insights—and maybe a few fun facts. *** # Speakers ## Susanne Pieterse As an autodidact full-stack engineer and iSAQB-certified software architect, Susanne thrives on innovation, learning, and knowledge-sharing, with tea and a heavy-bag boxing workout fueling the journey. She helps Java developers, who are eager to explore generative AI, transform their ideas into high-value, real-world creations. *** ## Jos Roseboom Jos gets a smile on his face when he makes other people happy by letting a computer do what they don’t like to do. He has been trying to do so professionally for the past 16 years. In his spare time, Jos likes to play tennis. He is a trainer/coach for kids playing the typical Dutch sport korfball.

Op dinsdag 12 mei organiseren we weer een SIDN TechTalk! Dit jaar is voor ons een speciaal jaar, SIDN bestaat namelijk 30 jaar en het .nl-domein bestaat zelfs 40 jaar. Een echt jubileumjaar dus! Al 30 jaar zorgen wij met trots voor het .nl-domein, een van de grootste en veiligste landendomeinen ter wereld! Dit jubileum laten we natuurlijk niet stilletjes voorbijgaan. Daarom staat deze TechTalk in het teken van 30 jaar SIDN en 40 jaar .nl. Ook dit keer hebben we 2 interessante sprekers én een lekkere maaltijd.

We’re heading out for a beautiful cross border hike through forest, heathland, open landscapes, and a very special midpoint stop: **De Achelse Kluis**, a historic abbey on the border between the Netherlands and Belgium. The hike starts in the Netherlands and takes us through the peaceful **Leenderbos**, one of the most atmospheric forest areas in North Brabant. Expect woodland paths, sandy tracks, heath, open views, and that lovely Veluwe style feeling of moving between forest and open landscape. As we continue south, we make our way toward the Belgian border and our main break location: **De Achelse Kluis**. This unique abbey complex lies between **Hamont Achel** and **Leende**. With roots going back to the 17th century, and later known as a Trappist abbey, it offers a beautiful neogothic setting with a brasserie, abbey shop, and a calm historic atmosphere. After several kilometers of forest and heathland walking, arriving at the abbey will feel like a real reward. We’ll take our longer break here, with the option to enjoy the brasserie, have a coffee, try Limburgse vlaai, taste an abbey beer, or simply relax around the grounds. After the break, we cross back into the Dutch side and return through the Leenderbos, completing a full loop through forest, heathland, and quiet countryside. A hike with forest energy, abbey atmosphere, monks’ history, and a touch of Belgium. 📲 **WhatsApp group** I’ll open a temporary WhatsApp group for everyone signed up before the hike, so we can coordinate carpooling, final break arrangements, and any last minute updates. **📍When and where to meet?** We’ll meet at 11h15 at Busstop "Leende, Valkenswaardseweg/A2"" https://maps.app.goo.gl/Uij4AmfEos2foDbQ8 ⏰ **We start walking a few minutes after meeting up** We don’t wait for latecomers, as we have a long route ahead and want to enjoy the full day properly. **🚗 Coming by car?** Please check your parking options beforehand so you arrive on time. **⏸️ Planned Breaks** After around **10 km:** 60 minute break at **De Achelse Kluis** I still need to confirm the practical arrangements with the brasserie, including whether we can just have drinks or whether we need to order food as well.

\# This meetup is around a third\-party organizer\, Focus Filmtheater\. You can either purchase your ticket online or right before the session\. **Seats are numbered**. We can meet for a drink before the movie. # **Title**: A Useful Ghost **Language**: Thai **Subtitles**: English **Length**: 130 min **Director**: Ratchapoom Boonbunchachoke **More info**: https://www.focusarnhem.nl/agenda/english-subs-a-useful-ghost/ **Ticket link: https://www.focusarnhem.nl/tickets/144298/** **Synopsis**: *A Useful Ghost* is a genre-smashing combination of fantasy, horror, romance, comedy, art house and everything in between. After the death of an employee at a family-run appliance factory, a strange phenomenon occurs. Spirits are possessing their products. This turns out to be good news for March (Wisarut Himmarat), the son of the factory owner, who is deep in mourning following the dust-poisoning death of his pregnant wife Nat (Davika Hoorne). March is reunited with his beloved in the form of a vacuum cleaner. Changing the social conception of ghosts, Nat’s love makes her decide to be of service by getting rid of the useless ghosts. Alongside the tale of the couple is the story of a repair guy (Wanlop Rungkumjud) who shows up at the door of a self-declared “Academic Ladyboy” (Wisarut Homhuan) to fix another possessed vacuum. The intertwining stories and unimaginable turn of events reveal complex layers and deeper context beneath the setting dust. Don’t let the breathtaking images fool you. There is more than what meets the eye! **How it works**: I will be at Focus around 6:15, where we can meet before the movie starts and have a drink. You can message me to find us. Screening starts at 6:45. Hope to see you soon!

**Liebe Gophers,** am 13.Mai geht es bei uns um eines der wichtigsten Patterns in verteilten Systemen: das **Transactional Saga Pattern**. Wer mit Microservices arbeitet, kennt das Problem – eine Bestellung aufgeben klingt einfach, aber dahinter stecken Payment Service, Inventory Service, Shipping Service... und jeder hat seine eigene Datenbank. Was passiert, wenn mittendrin etwas schiefläuft? Klassische ACID-Transaktionen funktionieren hier nicht. Sagas schon. Unser Speaker Mark Borukhov zeigt, wie das Saga Pattern funktioniert – mit echtem Go-Code, einem E-Commerce-Beispiel und Live-Demo. **Was euch erwartet:** * Warum verteilte Transaktionen ein echtes Problem sind * Saga Pattern: Konzept, Choreography vs. Orchestration * Implementierung in Go – Schritt für Schritt * Pitfalls, Lessons Learned & Q&A Das Event richtet sich an alle – von Go-Einsteigern bis zu erfahrenen Entwicklern. Auch wer Go nicht kennt, aber Microservices baut oder Patterns liebt, ist herzlich willkommen. **Der Vortrag wird auf Deutsch gehalten.** Wir treffen uns um 18 Uhr bei [lynqtech](https://www.lynq.tech/). Mit dem Vortrag starten wir um 18:30 Uhr. Danach wollen wir über Technologien und Erfahrungen plaudern, voneinander lernen, Kontakte knüpfen und einfach eine tolle Zeit miteinander verbringen. Wir freuen uns auf euch! 🚀 *Mark & Anna*

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.
