SAML

**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.

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. Laat je inspireren en kom op 12 mei naar de SIDN TechTalk. Meld je snel aan! **Programma** **18.00 – 19.00 uur: inloop met (buffet)diner** Zorg dat je nog niet gegeten hebt, want wij zorgen voor een lekkere gratis maaltijd! **19.00 – 19.45 uur Talk 1:** **Een reis door 30 jaar aan SIDN-infrastructuur – Marc Groeneweg** Marc neemt jullie mee door 30 jaar aan SIDN-infrastructuur: van de tijd waarin .nl draaide op een paar servers en een flinke dosis pioniersmentaliteit, tot de moderne, robuuste en soms bijna eigenwijze systemen van nu. Het wordt een reis langs hoogtepunten, “creatieve oplossingen” en technische keuzes die ons hebben gebracht waar we staan - en waar we soms achteraf om kunnen lachen. Laten we beginnen aan deze tijdreis door 3 decennia techniek… zonder rollbackplan. *Over Marc Groeneweg* Marc is senior DNS-engineer en product owner met ruim 20 jaar ervaring bij SIDN, met uitgebreide expertise in het ontwerpen, beveiligen en beheren van autoritatieve DNS-diensten en wereldwijde DNS-anycastinfrastructuren. Bedreven in DNSSEC, zonebeheer, DNS-publicatieprocessen en grootschalige netwerkinfrastructuren. Beschikt over een sterke achtergrond in ICT-projectmanagement, securityarchitectuur en procesverbetering. **19.45 – 20.30 uur Talk 2:** **Digitale autonomie: gisteren, heden en in de toekomst – Daniel Karrenberg** Daniel neemt je aan de hand van een reeks persoonlijke verhalen mee langs de ‘geboorte’ van .nl en RIPE in de Amsterdamse Watergraafsmeer, via individuele keuzes voor meer autonomie tot strategieën voor de toekomst. Wat hebben wij geleerd en wat kunnen wij doen nu en in de toekomst op het gebied van digitale autonomie? Discussie gewenst! *Over Daniel Karrenberg* Daniel Karrenberg is een van de pioniers van het internet in Europa. In de jaren 1980 hielp hij bij de opbouw van EUnet, de eerste pan-Europese internet service provider. In die tijd deelde hij een kantoor met Piet Beertema, de eerste beheerder van .nl. In 1989 was Daniel een van de oprichters van RIPE (Réseaux IP Européens), het belangrijkste samenwerkingsforum in Europa voor internetcoördinatie. In de jaren 1990 leidde Daniel de oprichting van het eerste regionale internet registry ter wereld, RIPE Network Coördination Centre (RIPE NCC), dat Europa, het Midden-Oosten en eerder ook delen van Afrika en Centraal-Azië bedient. Daniel was CEO van RIPE NCC van 1992 tot 2000 en chief scientist van 2000 tot 2013. In deze rol heeft hij een groot aantal activiteiten geleid, waaronder de RIPE Routing Information Service (RIS), het wereldwijde meetplatform RIPE Atlas, de DNS Monitoring Service (DNSMON), RIPEstat en, samen met NLnet Labs, de Name Server Daemon (nsd). In 2001 ontving Daniel de gerenommeerde Jon Postel Internet Service Award "voor twee decennia van buitengewone toewijding aan de ontwikkeling van netwerken in Europa en wereldwijd"; in 2012 werd hij opgenomen in de Internet Hall of Fame. **20.30 - 21.00 uur: Napraten onder het genot van een borrel.** **Taal** De sessies zijn in het Nederlands. **Meenemen** Identiteitsbewijs **Aanmelden/afmelden** Het bezoeken van TechTalk is gratis. Wij maken natuurlijk wel kosten. Heb je je aangemeld, maar kan je er toch niet bij zijn? Meld je dan snel af, dan kunnen wij jouw plek aan een ander geven.

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.

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!

**Welkom bij Coding Wednesday!** Samen duiken we in de creatieve wereld van programmeren. Elke maand is er een challenge of workshop gericht op coderen. In de regel maken we gebruik van de programmeertalen die je bij Novi leert (Python, Javascript, Java) **Wat doen we deze keer?** Altijd al samen willen werken aan een programmeerproject? Deze Coding Wednesday bouwen we een website na met de hele groep. Iedereen krijgt een apart onderdeel om te designen. Dit doen we met HTML, CSS en het Javascript framework React. De onderdelen worden met pull requests samengevoegd in het Github project. **Heb ik voorkennis nodig?** Het is handig als je al wat programmeerervaring hebt en hebt gewerkt met Github. Zo niet, kijk vooral mee om iets op te steken. Of werk met iemand samen! Uiteraard kan je je voorbereiden met online tutorials. **Wat heb je nodig?** * Je eigen laptop met WiFi aansluiting * Installeer een **code editor**. Novi studenten kunnen Webstorm of IntelliJ gebruiken. Anders is [VSCode](https://code.visualstudio.com/download) een prima editor * Zorg dat je een Github account hebt en Git hebt geinstalleerd. Tip: oefen vooraf met een dummy project om te zien of je code kan toevoegen vanaf een pull request. **Is er een minimum aantal aanmeldingen?** Coding Wednesday gaat door als er 5 aanmeldingen zijn of meer. Dus vergeet vooral niet om je aan te melden :) Mocht het niet doorgaan, laten we dit hier weten voor 13 mei 12:00 uur! Details: 📅 Wanneer: Woensdag 13 mei 2026, 14:00 uur (tot uiterlijk 17:00) 📍 Waar: Op locatie! Newtonlaan 247, Utrecht (4e etage)

Whether you're Deaf, HoH, an interpreter, an ASL student, or just want to learn or practice American Sign Language (ASL), we welcome all levels of signers to come join us for an evening of ASL socializing and practice. This event occurs on the first and third Sundays of every month, in the heart of Fairfax County at the Fairfax Wegman's (corner of Route 29 and Monument Drive). We can be found on the upper level, typically near the stairs. We generally start around 7 pm. ASL beginners are welcome, but you should know the ASL alphabet and some basic signs - this is not an ASL class, but the more experienced signers are generally happy to help beginners learn and improve. There is no better way to develop your signing skills than by joining the conversation with other signers. There is a place for everyone to join, learn and practice. Regardless, we are always welcoming so don’t be discouraged to attend; this is very informal and new folks are always welcome. Note, some attendees arrive early and grab some of Wegman’s food for dinner, so you can combine a shopping trip with the ASL practice.

As a solo operator, James currently manages every aspect of the business — from marketing and pricing to service delivery, quality control, and operations — while laying the groundwork for future growth. *** ## **Who James Is Looking to Hear From** James would especially value feedback from: * Business owners who have scaled service-based businesses * Operators of route-based or recurring revenue businesses * Entrepreneurs who have transitioned from corporate roles to hands-on work * Founders who have built teams from a solo operation * Anyone with experience in pricing, local marketing, or service scaling *** ## **Current Business Focus & Challenge** James is in the **early growth stage**, focused on building a foundation for scale through recurring storefront contracts and refining his pricing model. He is seeking feedback on: * Pricing strategy in a competitive, price-sensitive market * Whether to display pricing publicly or use promotional strategies * When and how to invest in advertising (where, how much, and when) * Timing and approach to hiring and team building * Balancing market penetration with long-term profitability This is a critical stage where the right decisions can significantly impact long-term growth and scalability. *** ## **Why Attend?** * Gain insight into building a service business from the ground up * Provide feedback on pricing, marketing, and scaling strategy * Connect with entrepreneurs navigating similar growth stages * Be part of a practical, real-world business conversation *** ## **About 1 Million Cups** 1 Million Cups is a national program that brings entrepreneurs and communities together to learn, connect, and grow through presentations and discussion. Loudoun’s chapter meets on the 2nd and 4th Wednesdays each month. Join us on **May 13** for coffee, connection, and a conversation around building, pricing, and scaling a service-based business. We look forward to seeing you there.

Plenty of time at the end to connect and exchange cards! **Let's explore AI Tools that actually *work* in our day-to-day life!** *** #ChatGPT #Claude #Grok #Gemini #Perplexity #DeepSeek #NotebookLM #Cursor #GitHubCopilot #Replit #Windsurf #v0dev #Lovable #Zapier #Makecom #n8n #Descript #OpusClip #Synthesia #Runway #Sora #Kling #Veo #PikaLabs #LTXStudio #AdobeFirefly #Vidu #Hailuo #LumaDreamMachine #Wisecut #Elaiio #Capsule #Filmora #Gling #Magisto #AdobePremierePro #ElevenLabs #Suno #Udio #Soundraw #Riffusion #Mubert #BeatovenAI #AIVA #Loudly #SplashPro #Soundful #MagentaStudio #WavTool #MakeBestMusic #BandLabSongStarter #TadAI #EcrettMusic #Midjourney #DALLE3 #CanvaMagicStudio #NotionAI #Gamma #Fathom #FirefliesAI #MLX
