  • Mastering Event-Driven Design

    PLEASE 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.

  • Coven of Wisdom - HER - February `24 edition

    Join us for an exciting front-end technology meetup where you’ll get a chance to gain valuable insights and knowledge about the latest trends in the field. Don’t miss out on this opportunity to expand your knowledge, network with fellow developers, and discover new and exciting possibilities. And the best part? Food and drinks are on us! Brecht De Ruyte - The future of UI is "open" When dealing with more advanced UI elements there are a lot of things that go wrong. They impact performance, accessibility and have the tendency to create frustrations along the way. In this talk, I will be introducing you to the W3C community around Open UI, while also taking a little detour with the Anchoring API. By combining these future specs we'll take a peek at the future of styling custom UI by only using HTML and CSS, giving you less frustration, performance boosts and basic accessibility out of the box. As a bonus, we'll also have a little look at selectlist and exclusive accordions. Tim Dujardin - Why semantics matter Are you developing forms without labels? Is the < div > element your go-to element to provide 'structure' in your website or web application? Do you make use of < a href="#" > to create actionable elements? In this talk, I will guide you through accessible design, development and testing by exposing common misconceptions and how to handle them correctly in the future. The goal is to create awareness on how impactful our design and development decisions can be on the target audience. Want to give a talk?
