**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.

**⚡ AI & Coffee – In-Person Meetup in Metz** Since the community has been growing very fast in Luxembourg 🇱🇺, Vienna 🇦🇹, Bucharest 🇷🇴 and Belgrade 🇷🇸 we’re hosting now also events in Metz 🇫🇷! Join our in-person event on Saturday, 18 April from 15h00-17h00 in Les 3 lumières [65 Place St Louis, 57000 Metz, France](https://www.google.com/maps/place//data=!4m2!3m1!1s0x4794ddfb97809c5f:0xa3fbaf4da6636c4d?sa=X&ved=1t:8290&ictx=111). During the first part of the event, we will all gather in a circle/square format and introduce ourselves for 1–2 minutes. This gives everyone the opportunity to share who they are, what they do, and what they are looking for, while also getting to know the entire room by listening to others do the same. This has proven to be the most effective way to network with 15–30 people within one hour, and afterwards it allows you to connect more easily with those who sparked your interest. The introduction round is the most exciting part of the event, so please try to arrive a bit early to avoid missing the start 😊👆 Based on the great feedbacks, feel free to bring also your laptops if you’d like to show your work. People were very open to sharing approaches and projects, which sparked some truly deep conversations. AI is moving so fast that it’s hard to keep up alone. The best way to make sense of it is by meeting others, exchanging ideas, and hearing fresh perspectives. That’s what this meetup is about. \-\-\-\-\-\-\-\-\-\-\-\-\- ☕ We’ll gather in a local café for open conversations about: * AI news and trends (what’s real, what’s hype) * Sharing projects, ideas, and feedback * Supporting each other and creating new stories * Building connections with like-minded people 👥 **Who’s welcome?** Developers, entrepreneurs, investors, mentors, students, researchers, creatives — and anyone simply curious about AI. 💡 **What to expect** * Casual atmosphere, no commitment, no pressure * The host will share small icebreakers and sparks of AI news * The rest is up to you: meet, talk, connect, and exchange 🎉 The only cost is your own coffee or drink.

**You’re already getting up on stage. You’re writing. You’re performing. You’re grinding it out at mics.** But if you’re honest… some of those jokes could hit harder. Welcome to **The Tag Lab**, an accelerated, punch-up intensive designed specifically for comics who are past the “how do I hold a mic?” phase and ready to level up their material. This workshop zeroes in on the two things that separate solid jokes from killer bits: **1\. Finding the true kernel of your joke** We’ll strip your material down to its comedic engine, the sharpest, funniest core idea, and rebuild from there. **2\. Writing tags that stack laughs** Because one punchline is nice. Three punchlines? That’s applause breaks. You’ll learn how to: * Identify where your joke is ending too early * Add tags that feel organic, not bolted on * Heighten patterns without losing clarity * Tighten wording so every syllable earns its place This is not a beginner class. It’s for comics who are already performing regularly and want their existing material to punch above its weight. Bring jokes that are “pretty good.” Leave with jokes that consistently hit. If you’re ready to stop hoping for laughs and start engineering them, this workshop is for you. Participation is by advanced registration. Places are limited. [Book your spot here.](https://fienta.com/taglabfestrogen) **Your instructor** Erin Crouch is an American comedian based in Germany. In 2025, she was paid by the German Ministry of Foreign Affairs to tell jokes about Germans. She has been featured in Germany's largest comedy festival, Cologne International Comedy Festival in 2024, Boom Chicago Amsterdam (2021 and July 2024) Utrecht International Comedy Festival (2022) and Summer Comedy Marathon festival in Ohrid, N. Macedonia (2023). She teaches stand-up comedy for teens at the KMC Onstage summer camp in Kaiserslautern, Germany as well as starting stand up and roasting classes for adults with Festrogen for the last five years.

**PLEASE READ THE FOLLOWING IMPORTANT NOTES:** 1. The dates listed for this series are about 95% reliable. We are completing our 2026 schedule as we speak, so minor adjustments are still occurring. 2. Each class in this series has an attendance fee, though this first offering is free on a first-come, first-served basis. 3. Each class, from BOTH a sign-up and fee perspective, is a separate entity. **Introduction:** HTML5 is the foundational technology for modern web development, serving as the standard markup language for structuring and presenting content on the World Wide Web. Developed through a collaboration between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG), HTML5 provides a robust system of elements (tags) that tell a browser how to display text, images, and multimedia in a clear and meaningful way. It works in concert with Cascading Style Sheets (CSS) for presentation and JavaScript for interactivity, forming the core technology stack for virtually all websites and many web applications today. One of the significant advancements of HTML5 is the introduction of powerful new features and elements designed to improve functionality and simplify development. Key additions include native multimedia support via the \ and \ tags, allowing developers to embed media without third-party plugins. It also offers new form controls for better user input, such as date and email types, and introduces web storage capabilities to store data offline for enhanced performance. These features streamline the process of building rich, interactive web experiences. A significant focus of HTML5 is enhanced semantics and better structural organization of content. New semantic elements like , , , , and \ provide meaningful structure to documents, which aids in search engine optimization (SEO) and improves accessibility for assistive technologies. These elements define different parts of a webpage (e.g., a header for the top, a nav for navigation links, a footer for the bottom), making the code more readable and understandable for both developers and machines. This emphasis on clear structure helps in creating more logical and maintainable websites. Developing websites in today's competitive environment requires taking advantage of every technique you can to get the maximum exposure possible. Our HTML5 class will not only show you what's new in the HTML specification, but also the best way to develop optimized web pages that get the attention your client and/or company requires. **The breakdown of the four-class series is as follows:** **Class 1: Introduction to Web Structure and Basic HTML5** This class introduces the core concepts of web development, the history of HTML, and the fundamental structure of an HTML5 document. * **Topics**: * **Web Architecture Overview**: How browsers, servers, and web pages interact. * **HTML Fundamentals**: Understanding elements, tags, and attributes. * **Basic Document Structure**: Using !DOCTYPE html, html, head, and body. * **Text Formatting**: Headings (h1 to h6), paragraphs (p), and text-level semantics (e.g., strong, em, br). * **Lists and Links**: Creating ordered (ol) and unordered (ul) lists, and linking between pages using anchor tags (a). * **Activity**: Students create a basic personal webpage containing text, a list of hobbies, and a link to an external website. **Class 2: Semantic HTML5 and Multimedia Integration** Class 2 focuses on modern HTML5 elements that provide meaning (semantics) to content, improving accessibility and search engine optimization. It also covers adding images and multimedia. * **Topics**: * **Semantic Elements**: Understanding and implementing elements like header, footer, nav, section, and article. * **Images**: Adding images using the img tag and attributes like src, alt, width, and height. * **Multimedia**: Embedding audio and video content using the audio and video tags. * **File and Folder Structure**: Best practices for organizing project files and managing file paths. * **Activity**: Students refactor their Class 1 project to use a proper semantic layout and add an image and a link to a video file. **Class 3: Forms and User Input** This session is dedicated to building interactive HTML5 forms, which are essential for capturing user data and input. * **Topics**: * **Form Basics**: Using the form element, action and method attributes. * **Input Types**: Exploring various input types (e.g., text, password, checkbox, radio, date, submit). * **Form Elements**: Utilizing label, textarea, select, option, and button. * **Client-side Validation**: Implementing HTML5 validation attributes like required, minlength, and pattern. * **Activity**: Students build a complete contact form with different input fields, radio buttons, and basic HTML5 validation. **Class 4: Introduction to CSS3 and Basic Styling** The final class introduces Cascading Style Sheets (CSS) to style the HTML content and make the web pages visually appealing and accessible. * **Topics**: * **CSS Fundamentals**: The role of CSS, selectors, properties, and values. * **Integrating CSS**: Using inline, internal, and external style sheets. * **The Box Model**: Understanding margin, padding, border, and content for basic layout. * **Basic Styling**: Changing colors, fonts, and text alignment. * **Accessibility Basics**: Identifying principles of web design usability and accessibility, including ARIA labels. * **Activity**: Students apply an external CSS file to their Class 3 form project to style the layout, colors, and fonts, culminating in a well-structured and styled webpage.
