#This meetup is around a third-party organizer (Lux Nijmegen): you need to purchase your ticket online before # **Curious about the best short films of the moment? Go Short is back at LUX Nijmegen!** Since the festival schedule is huge, I picked out two blocks from the European Competition for the meetup. **Here is the plan:** * **19:15 – 20:45 \| Block 1: EU Comp 3** https://www.goshort.nl/en/festival-program/block?programId=2982&viewingId=5093 * **21:15 – 22:45 \| Block 2: EU Comp 4** https://www.goshort.nl/en/festival-program/block?programId=2983&viewingId=5102 Feel free to drop in for just one of the blocks, or stay for the double feature. **Ticket Info:** Tickets must be purchased online in advance. Be aware that the EU Competition blocks tend to be popular and might sell faster! If you want to join for both blocks, I highly recommend getting a **Day Ticket**. Otherwise, you can just book a single ticket for the specific block you want to see. **Tickets: https://www.goshort.nl/en/tickets** **Meeting point:** I will be at LUX right by the entrance, from 18:30 and during the break between the two screenings so we can meet before each block starts. **More info**: https://www.goshort.nl/en/go-short-festival-2026 Hope to see you soon!

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 would like to welcome you for our next BrabantPHP meetup. This meetup will take place in Den Bosch at Projuice Learning. Starting time: 19:00 (with food). **Talk - File Uploads and REST** So you have built your fancy JSON REST API, maybe even add a fancy OpenAPI spec of your API. And then you have to add file functionality to your REST API. You will notice that your API is not made for file uploads. What is the proper strategy to handle file uploads in a REST API? This talk is interesting for backend developers and API designers who work with REST APIs and need to support file uploads. If you’ve ever built a clean JSON API and then struggled with adding file upload functionality, this session will give you practical insights and strategies for handling it properly. You’ll especially benefit if you: * Build or maintain REST APIs * Work with PHP or other backend technologies * Care about good API design and developer experience File uploads may seem simple, but integrating them into a REST architecture introduces several design challenges that many developers encounter in real-world applications. **About Pieter Jordaan:** Pieter Jordaan is lead developer at Paqt and already active in PHP for 15 years. Pieter Jordaan worked with many PHP frameworks which gives him a good idea about different perspectives and solutions for handling a problem. The last 2 years he worked silently on his open source library Apie to have better tooling for Domain Objects. **Second talk - Frankenphp meets Web assembly** By Johnny van de Laar During the Dutch PHP conference the keynote by Johan Janssens showed different ways to use Frankenphp. During this small talk I will make an attempt to show some of the examples of how to use web assembly plugins within Frankenphp. I will also talk briefly about all different ways PHP van be used these days. **About the sponsor:** Projuice Learning is a SaaS platform that helps companies professionalize internal training. Our software is widely used in the food industry to structure onboarding, manage skills and qualifications, and support continuous employee development. From our office in ’s-Hertogenbosch, we build and improve Projuice with a small and dedicated team of developers. **About the location:** The location is at the Projuice Learning office near the Den Bosch train station, **Koningsweg 2** in **Den Bosch**. It's within walking distance of the train station. Parking is possible at the office, they are free parking spots. **About the meetup:** * attending the meetup is free (as in free beer); * free food (pizza) and free drinks are provided!; * food is available between 19:00 and 19:30; * the talk will start at 19:30; * spoken language is English unless not necessary; * suitable for novice to expert level;

## Love is in the air…! After the crazy success of our first event, we're back with more connection games! This time, the games will be much shorter (15-20 mins each) to allow for easier rotation. For those who're new here, Affinitee hosts slow dating events focused on discovering relationships built on compatibility over superficiality! **No more swiping, skip the bad dates!** ### *This is how it works:* 1\. Before you arrive at the meetup\, you fill in a fun 5\-10 minute questionnaire before registration below \(if you haven't already\)\. We explore different aspects of relationship compatibility using this questionnaire\. To make use of the pre-matching facility, we recommend registering on the website as well. You may sign up here [https://affinitee.eu/au-event-3](https://affinitee.eu/au-event-3) 2\. A match will be automatically assigned \(if available\)\, based on your given criteria \(age range\, children\, location etc\.\) as well as the overall compatibility score based on your questionnaire answers\. 3\. At the event\, you will be able to try out a multitude of board/card games that are specifically chosen to explore various aspects of relationship compatibility \(moral values\, decision making etc\.\)\. 4\. After each game\, you can choose to switch partners\, or continue with the same person\, based on input from either parties\. 5\. At the end of the event\, IF you did indeed feel a spark with someone at the event \(and it is reciprocated\)\, we help you arrange a date with them\. You do not even have to exchange contacts\! **[!!IMPORTANT!!]** We recommend signing up through our website to guarantee a match as early as possible. But of course, even if no match isassigned to you due to late registration or gender imbalance, a majority of the games are still played as groups! *So nobody gets left out and everyone has a chance to meet and match with other singles.* We believe in conscious, compatibility based matchmaking. Don't waste your time dating the wrong people!

'KAFKA ON THE SHORE' by Haruki Murakami 'The aging Nakata, tracker of lost cats, who never recovered from a bizarre childhood affliction, finds his pleasantly simplified life suddenly turned upside down. There is a savage killing, but the identity of both victim and killer is a riddle. Kafka on the Shore follows the fortunes of two remarkable characters. Kafka Tamura runs away from home at fifteen, under the shadow of his father's dark prophesy. The aging Nakata, tracker of lost cats, who never recovered from a bizarre childhood affliction, finds his pleasantly simplified life suddenly turned upside down. Their parallel odysseys are enriched throughout by vivid accomplices and mesmerising dramas. Cats converse with people; fish tumble from the sky; a ghostlike pimp deploys a Hegel-spouting girl of the night; a forest harbours soldiers apparently un-aged since WWII. There is a savage killing, but the identity of both victim and killer is a riddle. Murakami's new novel is at once a classic tale of quest, but it is also a bold exploration of mythic and contemporary taboos, of patricide, of mother-love, of sister-love. Above all it is an entertainment of a very high order.' ***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

This is a facilitated creative session — not a class. You'll receive a starting prompt, access to paint, collage materials, texture, and colour, then two and a half hours to follow whatever feels right. No instruction. No judgement. No wrong moves. I designed this for women who spend their days in logic, deadlines, or high performance — and who have quietly stopped making things just for the joy of it. This session is permission to start again. We work in a small, intentional group. Music plays. Tea is ready. What you make is entirely yours. ### ✅ What's Included * All creative materials (paint, canvas cards, collage, pastels, mixed media) * A starting prompt to spark your session * Curated ambient music and calm space * Tea, coffee, and light bites * Your finished work to take home * Optional group sharing at the end. *** ### 🎒 What to Bring * Yourself and an open mind * Comfortable clothes you don't mind getting paint on * Nothing else — everything is provided ### 📋 Activity Itinerary | Step | Title | What happens | | ---- | ----- | ------------ | | 1 | Welcome & settle in | Tea, introductions, no pressure | | 2 | Meet your materials | Explore what's on the table | | 3 | Receive your prompt | One sentence to start from serving as a gateway to the experience | | 4 | Make freely | 60 min of creative flow time | | 5 | Reflect & share | Optional — share or just explore what others created | | 6 | Wrap up | Take your work, leave lighter |

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
