Shut Up & Write!Âź in Doorn
Join us for some focused writing time. All writers and all experience levels are welcome and don’t worry, no one will see what you've written.

Once you’re all settled, take some time to chat with your fellow writers. Once everyone’s arrived, I will lead quick introductions and then set the timer for our quiet and focused writing session.

Almere Tech #34
**Building a Document Management System in the age of agentic AI** At this edition of the Almere Tech Meetup we welcome [David Stibbe](https://www.linkedin.com/in/dstibbe/) with a practical talk on building software in a rapidly changing AI landscape. In his talk, Lessons learned from developing a DMS in the age of Agentic AI, David shares the journey of developing the Document Management System at Dare. He reflects on how the system evolved, which technical and architectural choices were made, and what worked well or did not along the way. The talk focuses on real lessons from practice, especially in the context of emerging agentic AI. It offers insights for developers, architects, and tech leads who are building complex systems today and want to understand how AI is influencing both design and development decisions. The program is as follows: * **17.30** Door open, welcome drinks * **18.00**: Word of welcome by [Stijn Sprenkels](https://www.linkedin.com/in/stijnsprenkels/), serving of snacks * **18.15** Talk of David Stibbe * **18.45** Q&A, discussion * **19.00** Drinks and talks * **20:00** End Hope to see you all again soon!

AI Essentials for professionals
AI Essentials for professionals
We zien dat AI inmiddels door veel mensen en organisaties wordt gebruikt, vooral voor tekst, plannen en ideeĂ«n. Tegelijkertijd merken we dat dit gebruik vaak onzeker en oppervlakkig blijft. Mensen experimenteren, maar twijfelen: * Klopt dit wel? * Gebruik ik AI “goed”? * Haal ik er echt voordeel uit, of kost het vooral tijd? De kern van het probleem is niet een gebrek aan tools of kennis, maar een gebrek aan grip, overzicht en vertrouwen in het eigen oordeel bij het werken met AI. **Wat houdt deze workshop in?** We willen een kleinschalige pilot-workshop (halve dag) organiseren waarin we professionals helpen om: * AI anders te leren zien (als denkpartner, niet als antwoordmachine) * Bewuster vragen te stellen en context te geven * AI‑output te beoordelen in plaats van blind te volgen Het is nadrukkelijk geen technische training en geen overzicht van tools. Het is een leerervaring die zich richt op denken, beoordelen en professioneel gebruik. **Voor wie is dit bedoeld?** De Training richt zich op: * Niet-technische managers en professionals * Die veel werken met tekst, plannen en besluitvorming * Die AI al gebruiken (bijv. ChatGPT), maar daar nog te weinig zekerheid en rendement uit halen **Wat maakt deze aanpak anders?** * Interactief en herkenbaar: deelnemers werken met hun eigen praktijk en leren van elkaar * Beperkt en scherp: geen overload, maar drie kerninzichten * Veilig en menselijk: twijfel wordt genormaliseerd, niet weggepoetst Deelnemers weten na afloop wat ze “maandag anders doen” **Pilot** Deze workshop is opgezet als pilot. We verwachten dan ook eerlijke feedback om deze workshop nog gerichter in te kunnen zetten om professionals meer bewust te maken van de mogelijkheden en onmogelijkheden van AI. Deze workshop wordt verzorgd door Edgar Stormbroek en Ziryan Salayi 9:00 9:30 Inloop 9:30 - 12:00 AI in praktijk 12:00 - 13:00 Lunch 13:00 - 14:00 Vervolg AI in praktijk 14:00 - 14:30 Afronding en feedback

â„ïžđŸ”„ 20 km Winter Forest Hike: Wodan’s Trail & Castle Doorwerth 🏰đŸŒČ
â„ïžđŸ”„ 20 km Winter Forest Hike: Wodan’s Trail & Castle Doorwerth 🏰đŸŒČ
From the first steps, we enter what is truly my favourite forest in the Netherlands, located on the southern edge of the Veluwe. Unlike most Dutch landscapes, this area has real steep hills, rolling terrain, and a distinctly un-Dutch feeling, even though you are right in the heart of the country. In winter, quiet paths and pale light filtering through tall woodland along the Italian Road make the scenery especially striking. Halfway through the hike, we slow down for a cosy break at Castle Doorwerth. It is the perfect place to warm up with bites and drinks, enjoy the historic surroundings, and take a relaxed pause before continuing our walk. The route also passes the iconic Wodan Oaks. These ancient trees, estimated to be 400 to 600 years old, add a quiet sense of history and continuity to the landscape, which feels particularly powerful in winter when the forest is still, open, and calm. **📍When and where to meet?** We’ll meet at 10:50 at Wolfheze train station. https://maps.app.goo.gl/73ZsY4tHrmhBjF8HA ⏰ 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?** There is plenty and free parking next to the station. https://maps.app.goo.gl/6yR1resGumn1j4jq5 **⏞ Planned Breaks** After 12 km: Lunch break at Castle Doorwerth https://maps.app.goo.gl/qLe6DfxL8C6mKrmZA **💾 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. The Tikkie link has been removed as the event is now fully booked. If a spot becomes available due to a cancellation and you would like to take it, you can message me directly and I will share the Tikkie link with you. **👟 Good to know** * Refund policy: Cancellations are fully refundable up to 1 week before the event (This is Friday 9 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). Please include your Meetup name in the payment note so we can match it easily. * Friends joining: If you bring a friend, make sure they also register and pay. * What to bring: Snacks, lunch, and water/ or hot thee/ coffee (depending on the hike distance). * Stay connected: Join our WhatsApp group to be the first to hear about future hikes — ask for the QR code during the hike. * T-shirts: Fairwear-certified organic cotton, eco-friendly inks — €25. Sustainable, odor-resistant, and perfect for hiking. Let us know your size and we’ll bring one for you.
ManKracht Avond (Amersfoort)
ManKracht Avond (Amersfoort)
Ha mannen! Weer een reguliere ManKracht meetup op de vrijdagavond in Amersfoort! Zoals altijd is de intentie voor onze meetups op locatie om een gemakkelijke, veilige en open atmosfeer te ervaren waarin we allemaal kunnen delen of inbrengen wat ons bezig houdt als man. Uiteraard zijn tijdens de ManKracht Avond nieuwe deelnemers welkom, we streven zoals altijd naar een groepsgrootte aan van 6 tot maximaal 10 man. Hier kort wat belangrijke info op een rijtje: * De offline meetup begint stipt om 20:00, vanaf dat moment zijn de 'deuren' gesloten. We vragen je dus om uiterlijk 5 minuten van te voren aan te komen. Je bent vanaf 19:30 welkom. * De avond duurt tot ongeveer 21:30. Voel je vrij om daarna het gesprek met andere deelnemers voort te zetten op een andere locatie (café/bar/kroeg). * Graag op tijd de RSVP in te vullen i.v.m. beperkte plaatsen. Mocht je op tijd weten dat je verhinderd bent, graag je RSVP aanpassen zodat mannen op de wachtlijst op tijd weten dat ze toch kunnen deelnemen. * Voel je vrij om een vriend mee te nemen, geef dit in dat geval ook even aan in de RSVP. Hopelijk zien we elkaar weer en mocht je nog vragen hebben dan hoor ik het graag natuurlijk. P.S. voorlopige locatie is thuis bij Daniel, kan evt nog veranderen,

Nieuwjaarsborrel OSGeo.nl, QGISNL, OSM NL
Op 18 januari (ja, een zondag) organiseren de Nederlandse QGIS gebruikersgroep, Openstreetmap gebruikers en OSGeo weer de traditionele nieuwjaarsborrel. We heten iedereen deze middag welkom in de Kargadoor in Utrecht. Aanmelden graag via [onze Pretix aanmeldomgeving](https://pretix.eu/foss4gnl/nieuwjaar/). Toegang is gratis, maar we weten graag met hoeveel personen we rekening moeten houden... ook voor de borrelhappen! We heffen deze middag het glas op het mooie open nieuwe jaar, en geven ook een podium aan mensen die wat over hun open project willen vertellen. Er is een scherm beschikbaar, maar het idee is wel dat we het leuk en luchtig houden. Kort en snel werkt het beste in deze setting. Dus als je iets wil laten zien: super. Mail even aan [bestuur@osgeo.nl](mailto:bestuur@osgeo.nl), dan weten we welke verhalen we kunnen verwachten. Aanvang 14:00 Formele programma 15:00 Einde 17:30. Ter plekke kijken we wie er na afloop mee wil nog iets eten (eigen kosten).

Intro to GitHub Copilot: Your AI Pair Programmer - Chris Steele
Intro to GitHub Copilot: Your AI Pair Programmer - Chris Steele
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** GitHub Copilot is rapidly changing how developers write, understand, and maintain code. Powered by generative AI and deeply integrated into modern development environments, Copilot acts as an intelligent coding assistant, helping developers move faster while maintaining quality and focus. In this session, we’ll explore what GitHub Copilot is, how it works, and where it fits into a real-world developer workflow. We’ll break down what Copilot can (and cannot) do, where it can be used, and how licensing differs for individuals and organizations. Most importantly, this talk goes beyond theory with a live, hands-on demo showcasing Copilot inside the IDE and on GitHub, demonstrating how it can assist with code generation, refactoring, learning new APIs, and accelerating day-to-day development tasks. Designed for developers, technical leads, and engineering managers, this session provides a practical introduction to AI-assisted development, highlights best practices for getting value from Copilot, and closes with guidance on how to continue learning and evolving alongside this rapidly advancing tool. Attendees will leave with a clear understanding of how GitHub Copilot can enhance productivity, improve developer experience, and fit into modern software teams today, not someday. **YouTube Link** TBA

Columbus Code & Coffee 82 @ Improving
Columbus Code & Coffee 82 @ Improving
Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
Freestyle + Karaoke ! ! !
Freestyle + Karaoke ! ! !
**Karaoke Night**: Bring your glee club friends. Enjoy a flashback to your choir days. No chorus line. It's all you baby. Sing. Shout. Scream. Lip sync if you need to. But do show up and do have a good time. **On Freestyle night** \- just bring a bottle to share\. There is NO formal wine tasting like on other weeks\. Door charge is $10 \(cash or Venmo only please\)\. We may have some left over wines to clear out\! Glasses are provided\. Take Care\. See you there\. **Parking**: There are several public parking lots near the Alive614 hall. Please be careful to NOT park in private parking lots. They do tow. Check Google maps to scope out your space. Anyone who is early could easily find a parking space on the street nearby. I am told that the Chase parking lot is safe after hours. **Glasses**: 
will be provided. Please note that after the wine tasting, the EMPTY glasses need to be returned to the boxes at the service table. Please do not make me hunt down your empty glass. Please be gentle, our glasses are fragile. Uh, they are made of glass! **Food**: You are welcome to bring a snack to share. It is not required. Most people do though. If no one brings anything, there will be nothing. **Code of Conduct**: Though mostly understood, it’s still worth mentioning. We don’t have rules per se, but we highly discourage the following topics of discussion because they are likely to incite anti-social responses - Sex, Politics, Religion. Please don’t mistake this as an attempt to limit your free speech rights but rather a guide to a place and time for appropriate discussions. **After the lights go out**: After the last sip of wine, when we clean up and turn the lights out, if you still haven’t had enough of us, it is typical for a group to get together and go to a local eatery for food and/or drinks or coffee. Again, We look forward to meeting new members and reuniting with old friends. Sincerely, ***Paul Uttermohlen***, **Red 1 Realty** *Your Hilliard Wine Club Host*
