PLEASE RSVP SO WE DON'T HAVE TO USE `*overflow: hidden*` ON THE FOOD TABLE 🍕 An exclusive pre-conference gathering where CSS enthusiasts `*display: flex*` their knowledge! Organized by iO in collaboration with CSS Day 2025, this event has a `*z-index*` higher than your usual meetups. Whether you're a developer, a designer, or anyone interested in what happens in the latest in CSS and front-end — RSVP for an evening of learning, networking, delicious food, and inspiring conversations! 🚀 During this meetup, we'll `*transition*` through fascinating topics around CSS, browser APIs, accessibility, and other front-end developments in an environment for all knowledge levels. Join us for an evening where creativity meets technology in preparation for CSS Day 2025. Schedule 18:00 – 🚪 Doors open 18:15 – 🍕 Dinner served 19:00 – 📢 First Talk 19:20 – 📢 Second Talk 19:40 – 🍹 Short break 20:00 – 📢 Third Talk 20:20 – 📢 Fourth Talk 20:45 – 🥂 Networking & drinks 22:00 – 🍻 Wrap-up: See you tomorrow at CSS Day! First Talk: Keep Your UI in Motion - Carmen Ansio, Design Engineer at Lottiefiles Ever shipped a UI that looked great but felt kinda… flat? In this 15-minute flash talk, we’ll explore how to add personality and polish to your interfaces using just CSS no JavaScript and definitely no frameworks. We'll play with modern CSS properties that give you microinteractions, transitions, and subtle animations that actually feel nice. Not the classic hover: zoom stuff — we’re talking smart selectors, creative timing, and CSS that adapts and reacts like it’s alive. Think of it as motion design for people who like their UIs smooth and their codebases light. You’ll leave with a pocketful of tricks, ready to give your interfaces that extra spark ✨ the kind users notice, even if they don’t know why. Second Talk: You don’t know MathML. Almost nobody does - Vadim Makeev, MDN technical writer Do you speak math? Me neither. Still, math formulas have always been around: from Wikipedia articles to JavaScript APIs and even CSS docs. It looks so alien that I never had a clue how to express it on the web. Apparently, there’s a markup language for that. HTML for content, SVG for vector graphics, and MathML for math! And it’s pretty cross-browser, too. Let’s dive into the basics and quirks of the language of the universe. Even if math is not your love language, you might learn something interesting about the web platform. Third Talk: Let's get creative - Pim van Die, Senior Frontend Developer at iO In our day-to-day coding, we're all about serious stuff. Forms, tables, clean code, guidelines, best practices. But sometimes you need to throw the rules out and make something purely for fun. Think of it as digital doodling. Creating visual eye candy without constraints.This presentation introduces creative coding with CSS and visual tricks that might not make production code, but will hopefully make people ask "How'd you do that?" Let's make cool stuff just because we can! Fourth Talk: Beyond Borders (and Outlines): Crafting Inclusive Experiences with Modern CSS - Manuel Sánchez, Web Accessibility Specialist at Zeit Online This talk explores real-world accessibility challenges that developers commonly face. It demonstrates how modern CSS techniques—such as advanced selectors, and dynamic contrast—can offer elegant, inclusive solutions RSVP now to secure your spot at this pre-conference gathering! All are welcome, regardless of experience level. How to find us Easily reached by travelling to metro station Overamstel and walk 500 meters from there. See event images for the route.

Go to page for ::before{content: "CSS Day"} — Pre-conference MeetupWorstelen jij en je team met de dagelijkse uitdagingen van softwareontwikkeling? Voelt het soms alsof we, ondanks alle nieuwe tools en frameworks, fundamentele kennis over het bouwen van kwaliteitssoftware zijn kwijtgeraakt? Kom naar onze inspirerende meetup waar ervaren sprekers hun inzichten delen over tijdloze software-engineering principes en hoe deze toe te passen in de moderne context. Deze avond staat centraal hoe we waardevolle kennis uit het verleden kunnen combineren met hedendaagse technologieën. Schrijf je in voor een avond vol kennis, heerlijk eten en een mix van creativiteit en technologie! 🚀 18:00 – 🚪 Deuren open 18:15 – 🍕 Food & drinks 19:00 – 🗣️ Extreme Programming - The Knowledge We Lost - Jan Van Ryswyck 20:00 – 🍹 Kleine pauze 20:15 – 🗣️ Pimp je klasses! - Johan Vervloet 21:00 – 🙋♀️ Drinks 22:00 – 🍻 Tot de volgende keer? Extreme Programming - The Knowledge We Lost - Jan Van Ryswyck In de begindagen van deze eeuw introduceerde Extreme Programming (XP) een set van radicale, maar uiterst effectieve principes en practices voor softwareontwikkeling. Denk aan pair programming, test-driven development en continuous integration. Deze ideeën waren baanbrekend en hebben de manier waarop we software bouwen fundamenteel veranderd. Maar in de loop der jaren zijn veel van deze core concepts afgezwakt, verkeerd begrepen of zelfs volledig losgelaten. Jan Van Ryswyck, een ervaren technical coach en software craftsman, neemt je mee op een reis terug naar de essentie van XP. Waarom waren die practices zo krachtig? Wat is de onderliggende filosofie? En hoe kunnen we deze fundamentele lessen vandaag de dag opnieuw omarmen om betere, snellere en meer waardevolle software te leveren? Mis deze kans niet om je begrip van agile development te verdiepen en concrete handvatten te krijgen om de kracht van XP in je eigen projecten te ontsluiten. Laat je inspireren en ontdek hoe het herontdekken van deze "verloren" kennis je team naar een hoger niveau kan tillen. Pimp je klasses! - Johan Vervloet Als developers zijn we constant bezig met het vertalen van de complexe wereld om ons heen naar heldere, gestructureerde code. Classes vormen hierbij een fundamenteel bouwblok. Maar hoe vaak staan we stil bij de kwaliteit van deze basis? Zijn de classes die we dagelijks schrijven wel zo robuust, testbaar en onderhoudbaar als ze zouden kunnen zijn? Johan Vervloet nodigt je uit om kritisch naar je bestaande codebase te kijken en de potentie van je classes te maximaliseren. Tijdens deze sessie werpen we een scherp licht op klassieke class patterns die je ongetwijfeld herkent. Aan de hand van concrete voorbeelden ontdekken we verborgen pijnpunten en verkennen we praktische alternatieven die leiden tot een significant verbeterde codebase. Verwacht concrete inzichten en direct toepasbare technieken om je design skills naar een hoger niveau te tillen. Ben jij klaar om je classes te "pimpen" en de kwaliteit van je codebase structureel te verbeteren? 📍 Waar? Je vindt ons bij iO Herentals - Zavelheide 15, Herentals. Volg bij aankomst de borden 'meetup' vanaf de receptie. 🎫 Schrijf je in! De plaatsen zijn beperkt, dus RSVP is noodzakelijk.

Go to page for The Test Automation MeetupPLEASE RSVP SO THAT WE KNOW HOW MUCH FOOD WE WILL NEED Are you and your team struggling with event-driven microservices? Join us for a meetup with Mehmet Akif Tütüncü, a senior software engineer, who has given multiple great talks so far and Allard Buijze founder of CTO and founder of AxonIQ, who built the fundaments of the Axon Framework. RSVP for an evening of learning, delicious food, and the fusion of creativity and tech! 🚀 18:00 – 🚪 Doors open to the public 18:15 – 🍕 Let’s eat 19:00 – 📢 Getting Your Axe On Event Sourcing with Axon Framework 20:00 – 🍹 Small break 20:15 – 📢 Event-Driven Microservices - Beyond the Fairy Tale 21:00 – 🙋♀️ drinks 22:00 – 🍻 See you next time? Details: Getting Your Axe On - Event Sourcing with Axon Framework In this presentation, we will explore the basics of event-driven architecture using Axon Framework. We'll start by explaining key concepts such as Event Sourcing and Command Query Responsibility Segregation (CQRS), and how they can improve the scalability and maintainability of modern applications. You will learn what Axon Framework is, how it simplifies implementing these patterns, and see hands-on examples of setting up a project with Axon Framework and Spring Boot. Whether you are new to these concepts or looking to understand them more, this session will provide practical insights and tools to help you build resilient and efficient applications. Event-Driven Microservices - Beyond the Fairy Tale Our applications need to be faster, better, bigger, smarter, and more enjoyable to meet our demanding end-users needs. In recent years, the way we build, run, and operate our software has changed significantly. We use scalable platforms to deploy and manage our applications. Instead of big monolithic deployment applications, we now deploy small, functionally consistent components as microservices. Problem. Solved. Right? Unfortunately, for most of us, microservices, and especially their event-driven variants, do not deliver on the beautiful, fairy-tale-like promises that surround them.In this session, Allard will share a different take on microservices. We will see that not much has changed in how we build software, which is why so many “microservices projects” fail nowadays. What lessons can we learn from concepts like DDD, CQRS, and Event Sourcing to help manage the complexity of our systems? He will also show how message-driven communication allows us to focus on finding the boundaries of functionally cohesive components, which we can evolve into microservices should the need arise.
