Hi everyone, we are planning an OWS in Gaasperplas Oost before Tri Amsterdam. This is not an official event. You are responsible for your own safety, etc

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.

We are thrilled to welcome you to our 10th edition of the AI Native Netherlands, hosted at the [Yuma](https://www.weareyuma.com/en) headquarters in Amsterdam. This edition is capped at 120 attendees. Yuma's office has limited space, so once the 120 seats are filled, registration closes and additional signups move onto the waitlist. A massive thank you to our host, Yuma, for their generosity in providing the venue, food, and drinks for this evening and for supporting the Dutch AI engineering community. **We'll cover:** * What humans still bring to software building when AI is writing the code * Tackling technical and social complexity inside distributed, fast-moving systems with legacy at the core * How to evaluate AI agents in production and catch silent regressions in under an hour * What "AI Native infrastructure" looks like in the wild: prompt changes, harness updates, RAG documentation, model swaps **Speaker 1: [Nico Krijnen](https://www.linkedin.com/in/nicokrijnen/) ([Yuma](https://www.linkedin.com/company/weareyuma/))** An explorer at heart, Nico loves to navigate the ever changing technology landscape and find practical solutions to complex problems. For a big chunk of his career, he disrupted the DAM space by building an innovative file management solution called Elvis, which is being used by media organizations all over the world. Besides leading and supporting teams and giving direction, he likes to roll up his sleeves and experience first-hand how (and whether) the latest technologies work in the real world. He is never shy of making unconventional choices to achieve radical results. **Talk: The human side of coding** Now that AI's are writing our code, what is the value that we humans still bring to building software systems? Our tech stacks are exploding in complexity, systems are more and more distributed and fast-paced development leads to an ecosystem full of fragile legacy systems that provide the backbone of business capabilities. How do we tackle that technical and social complexity? Do we take the usual route and solve it by adding more tech or AI? Or is there another way? Even in the 80's, people realized that the theory of a system can't be transferred through code and documentation alone. It requires developers to work closely together. We need to encourage human collaboration across disciplines, backgrounds and personalities (including our new AI buddies). Learn how you can use your human power skills to better understand the problems you're facing and build systems that last! **Speaker 2: [Floris Weers](https://www.linkedin.com/in/floris-weers-61392b160/) ([Biscuit](https://www.linkedin.com/company/biscuit-so/))** Floris is an ML engineer based in Amsterdam. He was responsible for continued-pretraining (or mid-training) at Apple's Foundation Model team, contributing directly to Apple Intelligence. Before that, he finished his master's degree at the University of Twente while building games on the side. He is a named author on the Apple Intelligence Foundation Language Models tech report, which describes the \~3 billion parameter on-device model and the large server-based model powering Apple Intelligence features. His research work at Apple also spanned multimodal models, mobile vision transformers, and distillation scaling laws. **Talk: The silent failures of AI: how to evaluate?** AI doesn't crash when it fails. It quietly does half the job. We'll go over a systematic way to evaluate agents in real product settings, allowing us to catch regressions and decide within an hour whether to use a newly released model or stick with the previous setup. A side-effect of the evaluation framework is that no engineer is scared of touching system prompts, making deeper harness changes or adding documentation to the RAG systems. **Agenda:** 18:00 — Arrival, food & drinks 18:30 — Talk \#1 \| Nico Krijnen 19:15 — Talk \#2 \| Floris Weers 20:00 — Networking & more drinks 21:00 — Wrapping up **What to bring:** Just curiosity and questions. If you've been working through agent evaluation, RAG system updates, or human-AI collaboration in your engineering team. **Who is this for:** Platform engineers, AI/ML engineers, SREs, architects, and engineering leaders focused on building and validating reliable AI systems in production. **Where to find us:** Yuma (4th floor), Business Centre Pedro de Medina, Pedro de Medinalaan 1, Amsterdam. 15 minutes from Amsterdam Central using tram 26. Paid parking at Parkbee Sluishuis across the street. [Maps link](https://maps.app.goo.gl/bd353dgCFd4TkDEq8)

'HOMEGOING' by Yaa Gyasi 'Two sisters with two very different destinies. One sold into slavery; one a slave trader's wife. The consequences of their fate reverberate through the generations that follow. Taking us from the Gold Coast of Africa to the cotton-picking plantations of Mississippi; from the missionary schools of Ghana to the dive bars of Harlem, spanning three continents and seven generations, Yaa Gyasi has written a miraculous novel - the intimate, gripping story of a brilliantly vivid cast of characters and through their lives the very story of America itself. Epic in its canvas and intimate in its portraits, Homegoing is a searing and profound debut from a masterly new writer.' ***Please read the book and join us for a lively discussion (in English) about the contents during our afternoon book club meeting.*** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **PLEASE NOTE:** This is an IN-PERSON event in Amersfoort, The Netherlands. Please cancel your attendance in advance if you are unable to join, so that those on the waitlist can participate. Looking forward to seeing you all IN REAL LIFE then! Best regards, Sandra

We'll find a nice 50 km or so road route around https://www.komoot.com/smarttour/13539887 Nijmegen and finish up with a sauna session here : https://kuuma.nl/en/book-now/sauna-nijmegen-lent/ If there are at least 6 of us we can book the whole sauna for ourselves. The sauna is 15 bucks per person. Maybe we can also have some food together afterwards :)

Welcome, readers! Our May read is **_Kindred_ by Octavia E. Butler.** The story follows Dana, a Black woman living in 1976 California, who is suddenly pulled back to a Maryland plantation before the Civil War. She learns her survival is tied to a white slaveholder’s son. Forced to move between centuries, she must endure the brutal realities of slavery while fighting to hold on to her identity. Tense, intimate, and unforgettable, Kindred explores how the past refuses to stay buried. Looking forward to discussing with everyone! We will meet at Zaftig Brewing Co in their event room in the back. We are welcome to bring in our own food, but **drinks must be purchased at the bar.** Happy reading! 📖
