Cartography

#This meetup is around a third-party organizer (Focus Filmtheater): you can either purchase your ticket online or right before the session# **Title**: Left-Handed Girl **Language**: Mandarin **Subtitles**: English **Length**: 108 min **Director**: Shih-Ching Tsou **More info**: https://www.focusarnhem.nl/agenda/english-subs-left-handed-girl **Ticket link**: https://www.focusarnhem.nl/tickets/140395 **Synopsis**: *Left-Handed Girl* explores superstition, tradition and resilience through the innocent eyes of five-year-old I-Jing, in a funny, moving portrait of modern Taiwanese womanhood. An impressive solo debut from Shih-Ching Tsou, long-time creative partner of Sean Baker (*Anora*). Single mother Shu-Fen and her two daughters, teenager I-Ann and five-year-old I-Jing, return to Taipei after years of living in the countryside. The move brings a lot of obstacles for all three of them. Shu-Fen has to clean up her ex’s mess while also working herself to the bone at a small food stall, while I-Ann wants to stand on her own two feet but keeps making the wrong decisions. When her traditional grandfather tells the left-handed I-Jing that she is never to use ‘the devil’s hand’ again, three generations of family secrets suddenly begin to unravel. *Left-Handed Girl* largely takes place in Taipei’s covered night markets, where little I-Jing darts through the lit-up streets, looking for adventure. The film is director Shih-Ching’s solo debut, who previously worked as a producer for Sean Baker’s *The Florida Project*, *Tangerine* and *Red Rocket*, and co-directed *Soul Kitchen* with him. **How it works**: I will be at Focus around 18:30, where we can meet before the movie starts. You can message me to find us. Screening starts at 19:00. After the movie, we can have a drink together. Hope to see you soon!

*(🇬🇧 English below)* Voordat een bordspel of kaartspel kan worden uitgegeven, moet er veel aan het spel getest worden om zeker te zijn dat het leuk is, duidelijk is en altijd goed werkt. Daarom komen we **elke 2 weken** met spelauteurs uit de regio samen om prototypes van spellen te testen en ze zo beter te maken en misschien ooit wel gepubliceerd te krijgen. Om 8 uur verzamelen we bij [StartUp Nijmegen](https://startupnijmegen.nl/) voor een speltestavond. Afhankelijk van het aantal aanwezigen en prototypes dat er wordt meegenomen (neem zelf ook iets mee als je wilt) vormen we een aantal groepen. Bij kleinere spellen kun je in de loop van de avond van groep wisselen, bij grotere spellen moet je dat even overleggen. **Ook als je zelf** **geen spellen maakt** of een spel hebt dat je wilt testen, ben je natuurlijk van harte welkom. Het is voor ontwerpers heel fijn om de mening van zo veel mogelijk andere mensen te krijgen. En heel eerlijk: het testen van nieuwe spellen is ook gewoon heel leuk! We gaan door tot een uur of 11, maar voel je vrij al eerder naar huis te gaan. Er is **gratis koffie** **en thee** bij StartUp Nijmegen. Voor fris, bier of wijn wordt een kleine bijdrage gevraagd. StartUp Nijmegen ligt tegenover het station. De auto kun je parkeren in de naastgelegen Keizer Karelparkeergarage (50 cent per uur). Er is hier ook een afgesloten fietsenstalling. De testavonden in Nijmegen zijn elke **2e dinsdag** en elke **4e woensdag** van de maand.

Therefore, **every 2 weeks**, we gather with game authors from the region to test prototypes of games, thereby improving them and, perhaps, getting them published someday. At 8 PM, we gather at [StartUp Nijmegen](https://startupnijmegen.nl/) for a game testing evening. Depending on the number of attendees and prototypes brought (feel free to bring something yourself), we form several groups. For smaller games, you can switch groups throughout the evening, but for larger games, you should discuss this. **Even if you** **do not design games** or have a game you want to test, you are, of course, very welcome. It is very beneficial for designers to receive feedback from as many people as possible. And to be honest: testing new games is just a lot of fun! We continue until about 11 PM, but feel free to go home earlier if you wish. There is **free coffee** **and tea** at StartUp Nijmegen. A small contribution is requested for soft drinks, beer, or wine. StartUp Nijmegen is located opposite the station. You can park your car in the adjacent Keizer Karel parking garage (50 cents per hour). There is also a secure bicycle parking facility here.

We’re heading into the south eastern Veluwe for a stunning scenic route that stays wonderfully quiet and almost deserted for a big part of the way, before building up to a truly spectacular grand finale! After around 6 km we reach the mysterious “Altar of the Loenermark” (Altaar van de Loenermark). I have no idea what it is, so we’ll discover it together. From there we continue through the beautiful heather and forest landscapes of Loenermark, one of those places where the Veluwe feels wide, wild, and open. Next we pass one of the quirkiest monuments in the Netherlands: the Ijkbasis Loenermark 1957–2007, a tribute to the calibration of measurement instruments from the past. The calibration itself might not sound exciting, but the location absolutely is, right in the middle of wide open heather, with big skies and that endless Veluwe feeling. It also marks about 11 km into the hike, a perfect spot to take our lunch break. After lunch we walk straight through the iconic National Park Veluwezoom, famous for its rolling grasslands and its fluffy semi wild cows. To finish in style, we end at Paviljoen De Posbank for a well earned snack or drink with a view over what many call the most spectacular heather of the Netherlands, complete with rolling hills. From there we head down towards Rheden, where you can easily catch the train or bus home. This is not a loop hike! **📍When and where to meet?** We’ll meet at 10h at busstop Loenen, Leeuwenbergweg. https://maps.app.goo.gl/LC3nNJQo57B5NnSy8 We are leaving a bit earlier otherwise we will find Paviljoen Posbank closed, which would be very sad. ⏰ We **start walking a few minutes after meeting up** — we don’t wait for latecomers, as the forest calls and daylight is short this time of year. **🚗 Coming by car?** This is not a loop hike. If you park in Loenen, you’ll need to make your own way back from Rheden afterwards. **⏸️ Planned Breaks** After **11 km**: Lunch break at **Ijkbasis Loenermark** (bring your packed lunch, this spot is truly in the middle of nowhere) **20 min** [https://maps.app.goo.gl/S5vAEpadAJs93ZrC7](https://maps.app.goo.gl/S5vAEpadAJs93ZrC7) After **19 km**: Snack or drink at **Paviljoen De Posbank** [https://maps.app.goo.gl/wowuqj3sRY5hcid37](https://maps.app.goo.gl/wowuqj3sRY5hcid37) **💸 Payment** Please pay as soon as you sign up: To keep things fair for everyone, if we don’t receive your payment within 48 hours, we will need to remove you from the participant list. If there’s a waiting list, this will happen sooner (in less than 48 hours). If that happens, no worries — you’re always welcome to sign up again if there’s space. 🌟 Early Bird Deal! Join now for just €4 — available for 3 days (72h). After that, the price will be €5. https://tikkie.me/pay/59muhp2djpv45gc6hgh6 **👟 Good to know** * Refund policy: Cancellations are fully refundable up to 1 week before the event (This is Friday 23 January at 23h59). After this period, the fee becomes non-refundable. * Hike difficulty: Our hikes are moderately challenging. Please only join if you’re confident you can keep up with the group’s pace (5 km/ h)— it’s more fun for everyone when we can walk together without long waits. * If the pace is too challenging: We may kindly suggest you continue at your own pace. We’ll give you clear directions to the nearest bus or train so you can return comfortably. * At your own risk: You participate at your own risk, so please make sure you have appropriate insurance coverage for outdoor activities. * Payment note: With Tikkie we only see initials (e.g., J. Doe instead of John Doe).

Sustainable, odor-resistant, and perfect for hiking. Let us know your size and we’ll bring one for you.

**Context is becoming the missing link that transforms powerful AI models into truly intelligent systems.** In 2026, the next leap in AI comes from understanding *context* \- user intent\, environment\, history\, and goals\. This shift separates generic outputs from meaningful\, real\-world outcomes\. Join this Meetup to explore why context is the foundation of more reliable, human-centered, and transformative AI. We’ll dive into the role of **knowledge graphs** and how they help AI systems make sense of complex information and connect insights the way humans do. **16:30 - Welcome snacks and drinks** #### **17:00 - Talk 1** #### **Why Context Matters in AI – Grounding LLMs** Aniket Mitra will explore how enterprise data captures the *DNA of an organisation*—the what, where, when, who, how, and ultimately the why behind decisions. He will explain why siloed data limits AI-driven decision-making, and how knowledge graphs provide a unified semantic layer that enables trustworthy, AI-powered control towers across the value chain. **Aniket Mitra** – Aniket Mitra is the founder of Computationele Wetenschapsgroep (CW) which is a technology development SME that specialises in designing, building & scaling Knowledge Graphs for enterprise customers across industry verticals like retail, manufacturing & logistics. **17:30 - Talk 2** **Building Trustworthy AI in Regulated Sectors – Moonjelly, Knowledge Graphs, and the Context Layer** Surajeet Bhuinya will share how a dedicated context layer helps AI systems understand how organisations actually work. Using Moonjelly as a practical example, he will show how connecting people, documents, and processes into a living enterprise graph creates context unique to each industry and use case—leading to better decisions, clearer accountability, and real business impact. **Surajeet Bhuinya** – Surajeet Bhuinya is the founder of DataPebbles, a leading Data & AI company in the Netherlands. With 25+ years of IT experience, he operates at the intersection of data, AI, and innovation, building scalable, practical AI systems that deliver measurable business impact. He is also the founder of Moonjelly, a platform that connects people, documents, and processes into a living enterprise graph, enabling teams to understand context, see impact, and act with confidence. **18:00 - Talk 3** **ReviewGraph – Using Knowledge Graphs to Predict Customer Satisfaction and Extract Hidden Insights** Lifeng Han will present ReviewGraph, a graph-based framework that transforms customer reviews into knowledge graphs to predict ratings and uncover hidden insights. He will compare this approach with traditional NLP methods and LLMs, highlighting how knowledge graphs offer strong performance with lower computational cost, greater interpretability, and promising integration with RAG systems. **Lifeng Han** – Researcher, **[4D Picture](https://www.linkedin.com/company/4dpicture/)** Project. Dr. Han has authored 50+ peer-reviewed publications and previously worked at the University of Manchester on Healthcare NLP. His PhD focused on machine translation (ADAPT Centre, DCU, Ireland). **18:30 - 20:00 - Networking, drinks and snack**

**ArnhemJUG** We are excited to announce the first meetup of 2026. We are welcomed by OpenValue Arnhem for the January meetup! **Agenda** * 17:00 CET walk-in * 17:30 – 18:30 Food and drinks * 18:30 – 19:30 talk: **Bigger Unit Tests are Better - why small unit test classes will slow you down** by **Peter Schuler** * 19:30 – 19:45 break * 19:45 – 20:45 talk: **Creating effective and objective architectural decision records** by **Piet van Dongen** * 20:45 – 21:30 drinks **Bigger Unit Tests are Better - why small unit test classes will slow you down** Do you take care that every class in your system has a separate unit test class? Are you a proud Test-First advocate? A code coverage evangelist? Are you the Sonar police in your team? Do you take pride in knowing all the quirks of your mocking framework? Then this session might be a cold shower for you. You will see how the general approach to unit testing might harm your flexibility. But a few simple changes in your approach will make your life better, your coding faster, your refactoring easier and your understanding of the business requirements stronger. In this presentation, you will learn new strategies that will help you make your unit tests bigger. First, guided by clear code examples, we will look at why having many small test classes may harm you. Secondly, you will understand why making the tests bigger is such an important improvement. And lastly, you will learn techniques and tricks that will help make your unit tests bigger. **About Peter Schuler** Peter is a lifelong Java developer with a passion for TDD and code quality. Lately he has become a Java community lead for the Rabobank as a side hustle. In his off time, he likes to work in the garden or goes for a short run. **Creating effective and objective architectural decision records** Documenting decisions is like eating your veggies as a kid: they keep telling you it’s good for you, but you just hate doing it. Architectural Decision Records (ADRs) to the rescue! ADRs are perfect for just-in-time, just-enough documentation for engineering teams and organizations. During this session, you will learn how to make architectural decisions effectively and objectively by: * Learning the structure of a good ADR (no more walls of text that nobody reads anyway!) * Practicing how to turn subjective choices into objective ones (no more pros and cons lists and tribal conflicts!) * Creating editable diagrams, fast (no more spending hours wrestling tools that your collaborators don’t know how to use!) * Collaborating quickly with technical and non-technical stakeholders (no more hours of Tower of Babel meetings!) * Reporting the decision using effective language and fit-for-audience diagrams (no more writing reports that end up unread in drawers!) Do you want to learn how to facilitate good decision making without spending weeks looking for consent? Then join this session and you will walk away a better software architecture decision facilitator. **About Piet van Dongen** Piet van Dongen is a senior software architect and engineering consultant at OpenValue, helping organizations solve complex technology challenges through effective software practices.

Session Abstract **No Map Required: Geospatial Analytics Directly in Your Data Warehouse** Think geospatial analysis requires specialized GIS software? Think again. This session introduces you to shapefiles and spatial operations right inside your database—no mapping application required. We'll demystify shapefiles (what they are, how they work, and where to get them) and show you how nearly every modern database —from DuckDB to Snowflake, supports spatial operations. You'll see practical demos covering spatial joins, distance calculations, and how to determine if two shapes interact with each other. Whether you're a data engineer optimizing delivery routes, an analyst aggregating metrics by geography, or a BI developer building location-aware dashboards, this session will show you how to unlock powerful spatial capabilities already built into your database stack—no specialized tools required. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

Dale Gnidovec, Curator of the Orton Hall Museum of Geology at The Ohio State University, will be presenting a program he has wanted to share with us for a long time: Plate Tectonics. His description of his program: Continents on the move - Nothing in Earth history makes sense without moving continents - it tells us why mountains, volcanoes, minerals, and fossils are where they are. This talk examines the evidence for continental drift, why it was disbelieved, and explains how the more-encompassing theory of plate tectonics was developed and eventually proven. Dale is an energetic, incredibly knowledgeable, and very entertaining speaker and this will be another wonderful program by Dale. Hope to see you there! Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid.
