As a creative, you might recognise this: somehow you always end up with more craft and art supplies than you actually use. Maybe it was an idea you never got around to, maybe other materials just worked better, or maybe it was simply time for a good clear-out. Whatever the reason, those supplies deserve a second life! At this craft swap everyone brings the materials they no longer need. We put it all out on the table and from there it's up to you, browse around and take home whatever sparks your creativity. A fun and affordable way to find new supplies while helping each other free up some storage space. 🎨 It's also a great chance to chat with fellow crafters about what you like to make and get inspired by each other! * 🖊️ What can you bring? Think paper, pencils and markers, washi tape, beads, stickers, glue, wool, fabric, stamps, craft kits... basically anything craft-related that's been sitting unused * 📦 Anything unclaimed at the end of the evening you can take back home, donate yourself, or leave with the organiser who will pass it on to charity

Join us for the next Azure Thursdays meetup. On **May 7th** we are welcomed by **Sopra Steria** at their Headquarters in **Nieuwegein**. **Confirmed speakers:** * Wesley Camargo (Tata Consultancy Services) * Jacco Rademaker (4Dotnet) **Program:** 17:30 \~ 18:00 Walk-in 18:00 \~ 18:45 Dinner 18:45 \~ 19:30 First session by Wesley - Your Azure Is Wrong And I Can Prove It 19:45 \~ 20:30 Second session by Jacco - The long running battle between Azure DevOps and GitHub: finally peace? 20:30 \~ 21:00 Drinks & wrap-up **Session 1:** *Speaker:* Wesley Camargo *Title:* Your Azure Is Wrong And I Can Prove It Many Azure environments are functioning, but that doesn’t mean they are designed to scale, stay secure, or meet enterprise requirements. Short-term decisions like using Resource Groups as environments, relying on a single subscription, manual scaling, and adding governance only when problems appear often lead to fragile platforms that break under growth. In this session, we uncover the most common Azure architectural anti-patterns and explain how the Microsoft Cloud Adoption Framework (CAF) provides a practical path from “it works” to Enterprise Ready. The focus is on the Ready, Govern, and Manage phases, where platform foundations are defined and long-term success is determined. You’ll get a clear overview of key CAF design areas, based on real production environments, not theory: • Identity and access • Networking • Governance and security • Monitoring • Automation • Cost management **Session 2:** *Speaker:* Jacco Rademaker *Title:* The long running battle between Azure DevOps and GitHub: finally peace? Are you currently working with Azure DevOps, but also have an eye on GitHub for its AI features? Do you need the functionalities Azure Boards offers and would you also like to use with AI agents? Or has your organization heavily invested in Azure Pipelines, which you do not want to rebuild using GitHub Actions? And when you would move your repositories, will you still have your pull request history? You do not have to go all-in with GitHub and leave Azure DevOps behind. Why choose, when you can combine them! You'll learn how to connect Azure DevOps to GitHub, what features this will open up for you and what your workflow can look like. This session will help you decide on how to move forward with your team or your whole organization! **About Azure Thursday and this event:** ===> Read more about the sessions and speakers on: www.azurethursday.com \# ==========CODE=OF=CONDUCT========== If you join this event, you agree with our Code of Conduct.

Not everyone who has ever worked in academia chooses to continue their career there. Sometimes academic work turns out not to be the right fit; sometimes it is simply different from what you expected. Some people entered with high ideals that did not come to fruition. Have you worked in an academic setting for at least one year (roughly full-time), and would you like to reflect on your experiences with others who have since left? Join the Journal of Trial and Error event on May 7, from 20:00, at Utrecht University Library City Center. During the evening, we will engage in an open dialogue. Together, we will explore what lessons the university can learn for improving science and higher education, and how these insights might help make academia more sustainable and appealing for the next generation.

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!

Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at Factor-ij Amsterdam on Thursday mornings. Be it a book, blog, script, essay, dissertation, resume, melody, poem or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done. SCHEDULE: 11: 15 AM - Quick introductions 11: 30 AM - Timer starts: write for 1 hour 12: 30 PM - The End: chat, take off, or keep writing OPTIONAL SOCIALIZING happens at 12:30 pm after the writing is wrapped. Writing is very solitary. Connecting (and sometimes even commiserating) with other writers is a cool thing. BEING LATE IS OKAY: just show up and get settled, then check-in with me after the session. (I’ll be the person with the Shut Up & Write! sign.) If you were on time, please be willing to make room for the friendly latecomer. Happy writing and I look forward to seeing you at Factor-ij! What Should I Bring? Whatever you need to be able to write! Bring earbuds/earplugs if you want to block the cafe’s overhead music or the occasional conversation by other patrons. Please come with your devices pre-charged, since we probably won't be always sitting somewhere with charging possibilities. Other Important Details: Travel by public transportation: 1. Take Tram 26 from the central station Amsterdam, and step out by the last stop. 2. Take bus 66 from the Amsterdam Bijlmer station, step out by Pieter Oosterhuisstraat, and further walk in the direction of the bus till the corner. FREE Wifi. Compulsory consumption is not required, but please do order a drink to honor our generous host.

For our next hike we'll be following a beautiful 9.5km route starting at Soest-Zuid train station and ending at Amersfoort Central Station. On the way we'll pass by the Soesterduinen dunes and the Birkhoven forest. Will you join? Utrecht Hiking Community aims to organise one hike per month in the Utrecht Region. Anyone is welcome to join, no matter whether you're a beginner or an experienced hiker, a local or an expat, a professional or a student, as long as you bring a good mood. We are not about fast hiking, but about social hiking: being active, exploring places, meeting like-minded people and just generally having a fun walk. We'll be starting from Soest-Zuid train station at 10.30AM. This time we won't be following a circular route, which means we won't end at our starting point, but we'll end at Amersfoort Central Station instead. Those who want to return to Soest-Zuid station afterwards to get back to their car, can take bus 70 from Amersfoort, which is going every 15 minutes. Please try to arrive to Soest-Zuid on time. We'll start our hike at 10.30AM and won't let the whole group wait for you in case you're arriving later. Only in case the train scheduled to arrive at 10.24AM has some delay, we'll wait for that train to arrive. If you're arriving after we have departed, you can send a message on WhatsApp to +31621177691, so we can share our location with you and you can try to catch up with us. Soest-Zuid station has a toilet, but please don't count on it to work. When checking the route, it was closed. On the way there are no public toilets, so please use a restroom before you arrive. The route is going over both paved and unpaved roads and we'll even be walking through the sand of the Soesterduinen dunes for a bit (not for long, as it's harder to walk through the sand than on the paths). Please wear good shoes, bring something to drink for on the way and use SPF if it'll be a sunny day Dogs are allowed on the route, but need to be kept on a leash on parts of the route. After the walk, those who want can join for lunch/drinks in the center of Amersfoort. This is not directly next to Amersfoort Central Station, but at a distance of another 15-20 minutes of walking. Since we do make some costs while organising our hikes (MeetUp subscription, travel expenses), a small donation would be very much appreciated. You can do so by following this link: https://www.ing.nl/payreq/m/?trxid=s9tT34cUyD97YuSHhIYbTIqN4LfxLAn9 If you have any questions, please feel free to ask. See you on Saturday 9th of May at Soest-Zuid train station!

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!
