Algorithms

**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.

Wir bringen dieses neue Meetup zu euch, bei dem wir uns das Konstruktionsprogramm "Onshape" (https://www.onshape.com/en/) ansehen. In den ersten Terminen wird Gerhard uns eine Einführung geben. In weiteren Schritten werden wir uns darüber austauschen.

Do you love to talk about books, and you want to practice your English? Perhaps your German isn't so good, but you are itching to share a great book you read with others. Come join the new Bookclub in English! Join our maiden voyage! Our first book selection is "The Shipping News" by Annie Proulx. I hope you love this book! Tell us all about it on our 13th April 2026 meeting! We meet on the second Monday of each month in a positive and welcoming space in the Chur Library: Stadtbibliothek Chur Grabenstrasse 28 7000 Chur After a brief round of introductions, we review and discuss the selected book of the month, in English! What did you think of the writing style? Did the author deliver a hidden message? Were you surprised to identify strongly with one of the characters? Let's talk about it. The discussion will be gently moderated to keep participants engaged and focused, to ensure a break, and to keep the meeting between 90 and 120 minutes, depending on the density of the book under discussion. As the discussion winds down, time is allotted for participants to propose and select next month's book. Perhaps the preceding discussion inspired you to recommend a relevant follow-up book. Or you would like to mix it up and switch to different genre, or perhaps to a lighter book of short stories, or poetry, or manga. Once the participants select the next book, they may purchase it at a 10% discount at Schuler Bücher.

**Integrating LLMs into Existing Applications: The Boring Approach** by [Luca Pircher](https://www.linkedin.com/in/lucapircher/) Or: the approach that actually worked for us. This talk covers how we found a use case we felt confident automating, the small bets we made along the way, and what we deliberately chose not to do. We'll share what worked, what didn't, and what we're still figuring out. No rewrites, no hype, no guarantees it'll work for anyone else. **Teaching PHPStan New Tricks** by [Christian Sciberras](https://www.linkedin.com/in/sciberras/) Extend PHPStan with custom rules and extensions to enforce domain-specific constraints and catch what default analysis misses. Make static analysis work for your codebase—not just against it.

**Beer, Pizza and IoT Meetup (Siemens Digital Twins Special)** AGENDA 18:30-19:00: Pizza and Beer (other drinks available) 19:00-20:00: Talk by Kazeem.Oladipupo and Ege Korkan on "Why simplifying IoT interoperability makes connected Digital Twins a reality?” 20:00-21:00: Networking with potentially more beer Look forward to seeing you all there. Due to limited capacity, we reserve the right to restrict admission. Pizza, beer and seats first come first serve! :)

Nach längerer Frühlingspause sind wir zurück! Der erste Webnesday im 2026 steht an. Der Event findet am 15. April 2026 um 19:00 bei der Liip AG in St. Gallen (im Neumarkt 5, Vadianstrasse 25a) statt. **My Take on Agentic Engineering** \| by [Pascal](https://www.linkedin.com/in/pascaleugster/) von [Inoo](https://inoo.ch/) Von Claude Code über Custom Skills bis zu Multi-Agent-Workflows: Wie ich als Solo-Entwickler meine tägliche Arbeit Schritt für Schritt an KI-Agenten delegiere. Ein ehrlicher Erfahrungsbericht – was heute schon funktioniert, wo die Grenzen liegen und warum Agentic Engineering mehr Mindset-Shift als Tech-Stack ist. **Design Systems from Scratch: Architektur, APIs und Best Practices** \| by [Steven](https://www.linkedin.com/in/steven-imhof/) von [Raiffeisen](https://www.raiffeisen.ch/) Ein Design System ist weit mehr als eine UI-Library – es ist das Fundament für Skalierbarkeit. Wir werfen einen Blick hinter die Fassade: Wie entwirft man langlebige Komponenten-APIs, die flexibel bleiben, ohne zur technischen Last zu werden? Von technischer Disziplin über Conventional Commits bis hin zu Architektur-Prinzipien, die jede Library stabiler machen. Ein Talk über Verantwortung und die Frage, wie man Tools baut, die Entwickler nicht nur nutzen müssen, sondern nutzen wollen. Wie immer habt ihr nach den Talks noch Zeit, eure Ideen und Fragen bei Bier und Pizza im schönen Liip Office zu besprechen. Vielen Dank [Liip AG](https://liip.ch/) fürs Sponsoring! Bitte meldet euch an, sagt es weiter und kommt zahlreich - wir freuen uns auf euch!

Liebe Atlassian Community, wir laden euch zum nächsten Atlassian Community Event Dornbirn/Bodensee ein. Dieses Mal sind wir wieder im Campus V in Dornbirn zu Gast – mit einem spannenden Abend rund um Cloud Migration, KI und HR Services. Nach einer kurzen Begrüßung durch Teresa, Andreas & Rainer erwarten euch vier praxisnahe Sessions: Confluence Cloud Migration: Herausforderungen, Aha-Momente und Best Practices Ramona Wörz (Uhlmann Pac-Systeme) teilt ihre ehrlichen Erfahrungen aus sechs Monaten Migration – für alle, die vor dem Schritt in die Cloud stehen oder bereits mittendrin sind. Anforderungsmanagement: Geht das nicht smarter als Excel? Ahmet Subari (Communardo) zeigt, wie Atlassian Rovo als KI-Brücke zwischen Idee und Umsetzung funktioniert. HR Services neu gedacht: Von Services zu Employee Journeys Stefan Hartmann und Luca Braun (Atlassian) zeigen, wie moderne HR-Prozesse skalierbar und durchgängig gestaltet werden können. Vom Prompt zur Forge App in 30 Minuten Kilian Warmdt (Uhlmann Pac-Systeme) baut live eine Atlassian App – per Vibe Coding, Schritt für Schritt. Zum Abschluss gibt es Pizza, Bier und Zeit für gute Gespräche. Meldet euch an und bringt gern Kolleg:innen mit – wir freuen uns auf euch! Teresa, Rainer & Andreas Agenda 5:00 PM: Check-in Ankommen, Namensschild schnappen, erstes Netzwerken. 5:30 PM: Welcome & Agenda Begrüßung durch Teresa, Andreas & Rainer und ein kurzer Überblick über den Abend. 5:45 PM: Confluence Cloud Migration: Herausforderungen, Aha-Momente und Best Practices Nach sechs Monaten Migration sind wir erfolgreich in der Confluence Cloud live gegangen und teilen unsere wichtigsten Erfahrungen aus der Praxis. Ramona Wörz (Uhlmann Pac-Systeme) gibt Einblicke in zentrale Herausforderungen, überraschende Aha-Momente und konkrete Best Practices - von Makros und Layouts bis hin zu User Management und Integrationen. Eine ehrliche Session für alle, die vor einer Migration stehen oder bereits mittendrin sind. 6:15 PM: Anforderungsmanagement: Geht das nicht smarter als Excel? Schluss mit dem manuellen Excel-Chaos: Dieser Vortrag zeigt, wie Atlassian Rovo als KI-Brücke zwischen Vision und Umsetzung fungiert. Durch die intelligente Vorstrukturierung in Confluence und die anschließende, menschlich validierte Überführung in Jira-Projekte wird ein nahtloser Workflow geschaffen. Ahmet Subari (Communardo) zeigt, wie sich die Präzision des Requirements Engineerings steigern lässt, indem generative KI gezielt als kollaborativer Partner in das Ökosystem integriert wird. 6:45 PM: HR Services neu gedacht: Von Services zu Employee Journeys - schnell, sicher, skalierbar Im Zentrum einer jeden HR-Abteilung sollte die Employee-Journey stehen. Wertvolle Zeit mit den Mitarbeitenden verbringen, das ist das Ziel. Vom Recruiting bis zum Offboarding, stets gut betreut. In der Realität muss die Zeit jedoch oftmals in die Beantwortung von Anfragen und zur Durchführung von manuellen Prozessen investiert werden. Teilweise sogar noch in Papierform. In dem Beitrag schauen wir uns an, wie es auch anders laufen kann. Stefan Hartmann und Luca Braun (Atlassian) zeigen, wie moderne HR Services neu gedacht werden können – von einzelnen Services hin zu durchgängigen, skalierbaren Employee Journeys. 7:15 PM: Vom Prompt zur Forge App in 30 Minuten Vom Prompt zur funktionierenden Forge App in nur 30 Minuten: Kilian Warmdt (Uhlmann Pac-Systeme) zeigt live, wie durch sogenanntes „Vibe Coding“ aus einer Idee Schritt für Schritt eine echte Atlassian App entsteht. Er zeigt, wie generative KI den Entwicklungsprozess unterstützt, Entscheidungen beschleunigt und auch ohne tiefes Vorwissen schnelle Ergebnisse möglich macht. 7:45 PM: Networking bei Pizza & Bier Zum Abschluss lassen wir den Abend locker ausklingen - mit Pizza, Getränken und vielen guten Gesprächen. --- Hosted By Andreas Immler, Community Leader Rainer Warmdt, Site Manager Teresa Burtscher, Community Leader --- Global Partner Atlassian (http://atlassian.com) Millions of users globally rely on Atlassian products every day for improving software development, project management, collaboration, and code quality.

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.

**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
