Information Architecture

**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.

This is our second meet-up, and we have a proper space this time: Luxembourg City Incubator, in the Gare district!😊 To kick things off, I’ll show for a few minutes how I actually use Claude Projects in my day-to-day. Not a tutorial. Just a look at how I use AI as a productivity tool. Then we open it up. We’ll talk about what AI actually means for us, where it’s useful, where it feels overwhelming, and what we’re still trying to figure out. We’re also continuing to shape what WIN AI is and what this community needs to be. Come as you are. Bring your questions, your doubts, and your curiosity. Tuesday 12 May — 7:00pm Luxembourg City Incubator 9 Rue du Laboratoire, 1911 Luxembourg

**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*

**✨ Gather & Grow – The First Circle** There’s a moment when you realize you’ve outgrown your current life… But you don’t yet know what the next version of you looks like. This event is for that moment. Gather & Grow is not just another meetup. It’s a space for people who want more- from themselves, from relationships, from life. For this first event, we’re doing something different. Instead of forcing a fixed topic, we open the space to explore what actually matters to you: – relationships and dating dynamics – confidence and self-trust – breaking patterns that keep repeating – personal growth, identity, and transformation Or anything else that’s been sitting in your mind, waiting for a place to be said out loud. This is a guided, intentional conversation—not random sharing. You will be seen, heard, and challenged in the right way. And here’s the truth: This first circle will shape everything that comes next. Future events will go deeper—real topics, real situations, real-time guidance. This is where we build the foundation together. **📍 Practical details** The event will take place at **I AM WOW, City Concord**. There is **free parking available**, so logistics are not your excuse. This is a café-restaurant space, so please keep in mind that ordering a drink is expected. 👉 Arrive **a little earlier** so you can order comfortably— we will **start on time**, together, without delays. If you’ve been craving better conversations, sharper insights, and a different kind of environment… you’ll feel it immediately when you walk in. Come as you are. Leave different. **🔒 A few important notes** This is not a passive event. If you come, come ready to **engage, reflect, and contribute**—in your own way and at your own pace. This space is for people who are open to growth, honest conversations, and new perspectives. Not for spectators, and not for staying comfortably the same. We keep the group **intimate**, so everyone has the chance to be part of the experience. Respect, presence, and confidentiality are expected. What is shared in the room, stays in the room. — Lanna

For this book club, I’d like to suggest a story about a woman who is simply trying to live in a way that will make society leave her alone. As usual, it doesn’t quite work out. Convenience Store Woman has been described by The Guardian as “a deadpan Japanese tale of an oddball shop assistant that possesses a strange beauty”. What struck me, though, was not its strangeness but its calm. Unexpectedly, the book helped me find reassurance in routine itself—in small, unnoticed actions, and in the permission to exist sometimes as a function, sometimes as a fictional character. I hope you are intrigued by now. If not, I would still encourage you to pick up Convenience Store Woman by Sayaka Murata— it is quite short! —and to join our discussion, where we will reflect together on questions of normality, meaning in work, and the fragile line between individuality and conformity. Links for inspiration: Convenience Store Woman by Sayaka Murata review – sublimely weird [https://www.theguardian.com/books/2018/aug/07/convenience-store-woman-sayaka-murata-review](https://www.theguardian.com/books/2018/aug/07/convenience-store-woman-sayaka-murata-review)

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City.

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.

**Building a great product is one thing—building momentum behind it is another.** Join **Senior Product Manager Adam Solaiman** and **User Experience Manager Tyson Smith** for a behind-the-scenes look at what it takes to turn complex ideas into scalable products inside large organizations. In this session, they’ll share how teams move from ambiguity to execution—navigating organizational complexity, aligning stakeholders, and continuously evolving products after launch. You’ll walk away with insights on how to: * Build and sustain momentum across teams * Adapt to changing priorities without losing direction * Scale products thoughtfully in complex environments Whether you're driving a new initiative or growing an existing product, this conversation will give you practical strategies to keep things moving forward. Come connect, learn, and swap stories with fellow product professionals. \-\-\- Food and drinks will be provided by Switchbox, our generous host. Free parking will be available at the front and back sides of the Switchbox Office.
