(English below / Engels onderaan) 🥳 We gaan afspreken, gewoon, voor de gezelligheid! [update] Het is toch een beetje ongewoon. We hebben een echte koude ijzige sneeuwrijke winter! Er is geen programma. Bepaal voor jezelf of je komt! 📅 Op 8 januari treffen we elkaar bij Danel Utrecht 👉🏿 Geen presentaties of programma. Laten we het een borrel noemen, maar voel je niet verplicht om alcohol te drinken. (En voor de duidelijkheid: consumpties voor eigen rekening. We hebben niks afgehuurd of iets dergelijks.) We komen samen met een groep gelijkgestemden en hebben de ruimte om lief en leed te delen. Starttijd 16:00 maar kom erbij wanneer het uitkomt: na je werk, na je avondeten, eet mee of niet, het maakt allemaal niet uit. We hebben de tijd! 🦠 Maskers zijn absoluut welkom. We hopen dat iedereen met COVID-gerelateerde klachten en/of een positieve test thuis wil blijven. Liever het zekere voor het onzekere. 🥂 Hopelijk tot snel! Ben je er niet bij en/of wil je mensen digitaal spreken? Kom bij ons [slack-kanaal](https://join.slack.com/t/idea11y/shared_invite/zt-8sp4de5x-i6RbV4GflD2uKHEszvb3nQ)! (English/Engels) 🥳 We're going to meet up, because we can, for social reasons! [update] Maybe we can't. We've got a real cold icey snowy winter! There's no programm. Decide for yourself if you're coming! 📅 We'll meet on January the 8th at Danel in Utrecht. 👉🏿 No presentations or agenda. It's more of a cocktail party, but don't feel like you're required to drink alcohol. (And just to be clear: everything is at your own expense. We didn't rent a space or anything alike) We'll come together with a group of likeminded people and have the opportunity to share our ups and downs. You're welcome at 16:00, or but join whenever suits you: after work, after dinner, join for a meal or don't, it doesn't matter. We're flexible! 🦠 Masks are absolutely welcome. We hope that everybody with COVID-related symptoms and/or a positive test will stay home. Rather be safe than sorry! 🥂 Looking forward to meeting up soon! If you're not present and/or want to have some digital conversation: join our [slack-channel](https://join.slack.com/t/idea11y/shared_invite/zt-8sp4de5x-i6RbV4GflD2uKHEszvb3nQ)!

**+++ IMPORTANT: Because of the weather conditions, the meetup will only be remote today: [https://meet.google.com/unm-veco-dxh](https://meet.google.com/unm-veco-dxh) +++** **Dear AWS users,** our January event will happen soon! Thanks to **Aclue** for providing us the space, drinks and food for this AWS User Group Meetup. **Agenda & Talks**: * 18:00 Warm-up * 18:30 - 19:15 **No Lambda, No Problem**: Building Functionless Serverless Workflows by Vincent Martens, Principal Consultant, Aclue * 19:30 - 20:15 **AWS re:Invent re:Cap** by Alexey Vidanov, Senior Consultant, Storm Reply * 20:15 - 21:00 Wrap up & Networking **No Lambda, No Problem: Building Functionless Serverless Workflows** While serverless frees us from managing servers, we still have to take care of application code, dependencies, and integrations. So why not go all in on managed services and embrace service‑to‑service communication? In this talk, we’ll explore how to build serverless workflows without any Lambda functions at all: which native cloud services you can combine, common integration patterns, and how to design “functionless” architectures. We’ll also look at the hard edges: where this approach breaks down, which trade‑offs you’re making in terms of vendor lock‑in, and when you really do need a function again. **AWS re:Invent re:Cap** AWS re:Invent once again delivered what everyone expects from the event: major announcements, fast keynotes, and a large volume of new services and features that are hard to process during the week itself. This year also included something unexpected. Werner Vogels’ final keynote appearance gave the conference a different tone and emotional weight. In this re:Cap session, we will quickly walk through the most relevant announcements from re:Invent, focus on what actually matters in practice, and share personal observations from the event, including why this re:Invent felt different from previous years.

**There is an assumption in product development that there must be some form of product discovery and/or preparation before “work” goes to teams. Hence, the assumed need for product discovery vs delivery processes. E.g. double diamond discovery process and division between so-called product folks and engineering.** **In this talk, I will show you why the double diamond and the related division between discovery and delivery is harmful, and with stories and practical advice give alternatives.** Check google for the venue, make sure you chose the 1 right entrance: [https://maps.app.goo.gl/3bxBB79PJbx6ZGqq8](https://maps.app.goo.gl/3bxBB79PJbx6ZGqq8) Food and Drink will be there! Venue: Verandert Gewoon Parking: Can be at the side of the street

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.

Welcome to the event page for the city trip to Tilburg, held on Sunday January 11th, 2026. This event has a meetup at Arnhem Centraal (11:40) and Tilburg station (13:00), so you can easily join us from anywhere in the Netherlands. This is a social event open to everyone to meet new people in a friendly environment while exploring a city together! ***Summarized overview:*** 11:40 Arnhem Station meetup, near Burger King 11:53 Departure Arnhem: 63 minute train ride 13:00 Tilburg Station meetup, near Starbucks\* 13:10 Group city walk 14:25 Choice: Free time or continue walk With a coffee break at a café if there’s enough interest 17:00 End U&R event… But at 17:00 the Sterrentocht starts from Willemsplein! Sign up by RSVP on Meetup, OR via [Google Forms](https://forms.gle/C6JCCUH68X7QbQtV7). Travel by your own OV-chipkaart. Contribution: €3,- pp (to help maintain our Meetup page). \**Train delays and cancellations could affect the meetup time in Tilburg. If this is the case, it will be announced in the discussion chat of this event page.* *** **City walk, Free time & Sterrentocht** This event consists partly of a group walk in the city center of Tilburg and partly of offering free time. The group walk is at a slow pace so you can connect with others, while enjoying the scenery of the city and taking photos along the way. In case of bad weather: bring an umbrella! After about 75 minutes, free time starts: we’ll check in if people like to continue our group walk or if there are other ideas to do in the city. For instance going to a museum, a café, do photography or anything else. If we continue our walk it will be at the same pace, we’ll go to new areas and if there’s enough interest we’ll go for a coffee in between. At 17:00 we’ll stop hosting the event, but on this day the Sterrentocht is organized in Tilburg, starting at 17:00 @Willemsplein. This is a real recommendation if you like light, arts and Dutch cultural events. **Meetup in Arnhem & Tilburg** This event has a meetup in Arnhem (11:40) and Tilburg (13:00), as described above.

For car users, I suggest checking the official municipality website to find parking spaces and what fares apply. U&R is originally based in Arnhem, but invites people from anywhere to join our travels. **Sign-up: RSVP on Meetup or Google Forms** Sign up for this event by RSVP here on Meetup or sign up via Forms: [https://forms.gle/C6JCCUH68X7QbQtV7](https://forms.gle/C6JCCUH68X7QbQtV7). Everyone is asked to pay a 3 euro contribution to help us maintain our costs on Meetup. This is refundable if U&R cancels the event or reschedules it to a different day, or if you cancel 72 hours before the meetup. Hope to see you in Tilburg!

**Doing KPIs Right: a KEY to Analytics (and AI!) Impact!** On the one hand, KPIs are such a Business 101 concept that it may seem a little silly to dedicate an entire session to the topic. On the other hand, KPIs get handled so poorly so often that a case could be made that this meetup could just be one of the most impactful sessions of the entire year! We’re starting off the year at a new location: [COhatch Upper Arlington](https://www.cohatch.com/locations/columbus/upper-arlington/) but with a familiar speaker, Tim Wilson! We’ll be back at Rev1 in February, when the speaker will presumably not be Tim. Tim will make the case that effectively measuring performance of projects, campaigns, and initiatives (and even meetups!) should be a foundation for any data analytics program. Topics covered will include: the “two magic questions” of performance measurement, how to help business partners distinguish between outcomes and outputs, and effective tactics for collaboratively establishing KPI targets. He will also stick his neck out by demonstrating some of these techniques in real-time by measuring whether his talk lives up to the promise of this description! All CBUSDAW events are free thanks to our 2026 Sponsors: Clarivoy, Conductrics, What Box Consulting Group, and Piwik PRO. Check out [cbusdaw.com](https://cbusdaw.com) for more information.

SQL Server 2025 delivers a major round of improvements across performance, security, manageability, and hybrid connectivity, and this session gives you a practical, no‑nonsense tour of what matters most. We’ll cover enhancements to the core engine, query processing, storage, and availability that benefit DBAs and developers regardless of where SQL Server runs. You’ll see how SQL Server 2025 aligns with Azure SQL’s roadmap while still supporting strong on‑premises and VM‑based deployments. We’ll highlight new management, monitoring, and troubleshooting capabilities designed to simplify operations and reduce firefighting. AI‑powered features exist in this release, but the focus here is on the foundational improvements you can use immediately. Whether you’re modernizing, maintaining, or planning your next upgrade cycle, this session will help you understand what’s new and how to prepare your environment and your team.

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.

**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
