Human-Computer Interaction

**Hey fellow AWS enthusiasts! ✨** This April we welcome **[Philipp Hoyer](https://www.linkedin.com/in/philipp-hoyer-621555174/)**, Lead Engineer at Rackspace Technology. He'll walk us through a journey of AWS' popular containerization services Amazon ECS and Amazon EKS running on Fargate by discussing which fits best for which use case, where EKS can make you go nuts and when ECS might shines brighter - or vice versa. **📆 Tonight's Agenda** 19:00 - Welcoming **19:15 - Talk by Phillip** 20:15 - Networking Thanks to our friends at **[CodeCam:N](https://www.codecamp-n.com/)** who open their offices for us and sponsor food and drinks for this evening. Looking forward to seeing you 👋🏻 Nora & Frank \-\-\- The talk ⤵️ **An AWS Container Journey - The Good, The Bad and The Ugly featuring ECS and EKS** EKS on Fargate promises fully managed Kubernetes with zero node management—but the reality is often more complex than expected. This talk explores the journey of building a production workload on EKS Fargate, starting with the initial motivations and architectural decisions. It uncovers three non-obvious pitfalls that only surface during real-world implementation, including challenges with load balancing, EFS integration, and logging. For each case, the underlying issues and the required workarounds are dissected to reveal the hidden operational complexity behind the “serverless” promise. Based on these insights, the talk takes a critical look at whether ECS on Fargate would have been the simpler alternative. It provides a concise overview of ECS, highlights its own limitations, and delivers a direct comparison between ECS and EKS. The session concludes with clear, experience-driven guidance on when to choose which service—helping teams avoid costly assumptions and make better architectural decisions in AWS container environments. The speaker⤵️ Philipp is a Lead Engineer at Rackspace Technology who enjoys turning complex cloud architectures into solutions that actually work in practice. He started in software development, moved through the DevOps world of pipelines, containers, and Kubernetes, and eventually specialized in AWS. He has built and operated cloud solutions ranging from big data and streaming platforms to containerized and serverless workloads. With experience in both insurance and automotive, his focus today is on real-world cloud challenges—especially the ones that don’t show up in the docs.

**Let op: RSVP via Meetup is géén directe aanmelding. De startdatum op meetup is niet de daadwerkelijke startdatum van de mannengroep; lees verder voor meer informatie** **Voor deelname plannen we eerst een korte intakecall. Na die call bevestigen we of deelname past.** **Stuur dus altijd eerst een mail naar: Info@modernmanhood.nl voor een kennismaking!** **www.Modernmanhood.nl** In een tijd waarin veel mannen in hun eentje worstelen, willen wij iets anders aanbieden: een plek waar je niet hoeft te presteren. Waar je mag vertragen, voelen en delen. De grote aanvraag bevestigt voor ons: de behoefte aan échte verbinding en verdieping onder mannen is groot. In deze mannengroep komen we om de drie weken samen met een vaste groep van maximaal 10 mannen. We creëren een warme, veilige setting waarin we onderzoeken wat het betekent om man te zijn, in relaties, in werk, in vriendschap en in het dagelijks leven. Je hoeft niets te fixen of op te lossen. Je hoeft alleen te verschijnen zoals je bent. Elke avond werken we met een thema zoals woede, kwetsbaarheid, angst, kracht of verbinding. We combineren rituelen, lichaamswerk, deelrondes en oefeningen uit o.a. mindfulness, ademwerk en systemisch werk. Alles in een sfeer van openheid, zachtheid en respect. Je doet een commitment per 4 sessies. Je betaalt vooraf voor elke reeks van 4 bijeenkomsten. De groep loopt door; na elke reeks kun je je opnieuw verbinden en blijft je plek behouden. Zo ontstaat er vertrouwen, diepgang en continuïteit in de groep. De eerste stap is een korte, vrijblijvende kennismakingscall, om elkaar even te spreken en te voelen of het past. Daarna krijg je praktische info via WhatsApp en kun je instappen zodra de nieuwe groep start. De definitieve datum wordt afgestemd op de groepsgrootte en beschikbaarheid van de deelnemers. Meld je gerust aan om op de hoogte te blijven! Aanmelden kan via: info@modernmanhood.nl of kijk op de website. Locatie: Nijmegen Investering in jezelf: €200 voor 4 sessies van 2,5 uur per sessie. Over de facilitators Deze mannengroep wordt begeleid door David Gelsing en Steyn Maréchal.

**Um was geht es dieses mal?** Dieses Mal findet das Meetup in Kooperation mit dem **n8n Meetup im Ruhrgebiet** statt und wird wie immer bei uns bei codecentric in Dortmund ausgerichtet. Beim 3. n8n Meetup im Ruhrgebiet geht es wie immer darum, die Möglichkeiten von n8n besser kennenzulernen, Erfahrungen zu teilen, voneinander zu lernen und sich mit anderen auszutauschen. Dieses Mal steht das Meetup zusätzlich im Zeichen von Vibe Coding und schnellem Prototyping. Im Fokus steht, wie sich n8n als Backend für Automatisierungen, Schnittstellen und Logik im Hintergrund mit Vibe Coding für die schnelle Entwicklung von Frontends verbinden lässt, um in kurzer Zeit funktionierende Prototypen, interne Tools und erste MVPs umzusetzen. Anhand konkreter Beispiele und Live-Demos zeigen wir, wie aus einer Idee schnell etwas Nutzbares entsteht. **Hybrides Setup!** Wir freuen uns, euch bei uns in den Räumen der codecentric AG in Dortmund willkommen zu heißen. Vor Ort versorgen wir euch mit Snacks und Getränken und freuen uns gleichzeitig über interessante Diskussionen und einen guten Austausch. Für alle, die es nicht zu uns ins Office schaffen, werden wir das Meetup Hybrid durchführen. Der Stream beginnt ca. 10 Minuten später, damit wir vor Ort ausreichend Möglichkeit für persönliches Kennenlernen haben. Den Live-Stream findet ihr auf dem [YouTube-Channel](https://www.youtube.com/@codecentricAG) der codecentric AG. **Wichtig - Absage bitte rechtzeitig:** Wir bestellen das Essen bereits 3 Tage vor dem Meetup. Falls ihr doch verhindert sein solltet, bitten wir euch um eine rechtzeitige Absage. Das ist wichtig, damit wir nicht unnötig Essen verschwenden müssen. Vielen Dank für euer Verständnis! **Anreise:** Per Zug: Vom Dortmunder HBF sind es ca. 10 Minuten zu Fuß. Mit dem Auto: Rund um das Office gibt es einige Parkflächen, dazu befinden sich in dem Parkhaus der Thier-Galerie weitere Parkplätze.

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.

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. 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. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

**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 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? 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

Sleep in on Sundays. When you've had your fill of pajama-time, roll out and have some tasty brunch with your fellow Humanists!

Curious about “vibe coding” but not sure what it actually means? This beginner-friendly talk is about how people are using AI to build websites, apps, automations, and small software projects by describing what they want in plain English. We’ll cover what vibe coding is, what AI is good at, where it falls short, and how to actually use it without getting lost. The goal is not to hype AI as magic — it’s to show how to use it as a practical tool. This session is designed for beginners, curious builders, non-programmers, and developers who want a clearer picture of how to build with AI today. Topics include: * What “vibe coding” means * What AI can help you build * Where AI is useful and where it is unreliable * A simple workflow for building with AI * Prompting tips for better results * Common beginner mistakes to avoid If you’ve ever thought, “I have an idea, but I don’t know how to build it,” this talk is for you. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

ASH is Atheists, Skeptics and Humanists of First Unitarian Universalists of Columbus Ohio TBD Snacks are usually available, and you are welcome to bringing something to share!
