  • 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? Send us your proposal at meetup.herentals@iodigital.com 18:00 - 19:00: Food/Drinks/Networking 19:00 - 21:00: Talks Thursday 8th of February, 18h00 - 21h00 CET iO Campus Herentals, Zavelheide 15, Herentals

The first talk by Urs Peter: Title: Moving from Java to Kotlin - is it worth it? Urs is a seasoned software engineer, solution architect, conference speaker, and trainer with over 20 years of experience in building resilient, scalable, and mission-critical systems, mostly involving Kotlin, Scala and Java. Besides his job as a consultant, he is also a passionate trainer and author of a great variety of courses ranging from language courses for Kotlin and Scala to architectural training such as Microservices and Event-Driven Architecture. As a people person by nature, he loves to share knowledge and inspire and get inspired by peers on meetups and conferences. Urs is a JetBrains certified Kotlin trainer. Abstract: With statistics painting a clear picture of its consistent growth, Kotlin is the rising star on the JVM. But, is it as bright as proclaimed? This talk will explore the journey you embark on when moving from Java to Kotlin. With many code samples, statistics, anecdotes, and a great deal of real-world experience, light will be shed on questions like "What are the benefits and drawbacks?’" and "How did we approach it?" Most importantly, we'll tackle the overarching question: "Is it genuinely worth it, and why?" By the end of this session, you'll have gained a solid understanding of the differences between modern Java and Kotlin, including the latest features like Virtual Threads. You'll know what to anticipate and gain when embracing Kotlin, including the required efforts and ingredients for a smooth transition. Armed with this knowledge, you'll be well-equipped to assess whether Kotlin is indeed worth the try. (edited) The second talk by Mehmet Akif Tütüncü Title: Discovering Kotlin's Magic: The Power of Properties Akif is a speaker at conferences and a senior software engineer focused mainly on the backend with more than 10 years of professional experience in software development.

Akif is proficient in Scala, Java, and Kotlin, using both object-oriented and functional programming. He has skills in CI/CD, testing, databases, cloud applications, and microservices and is a fan of open-source software. Abstract: Let's dive into Kotlin's cool feature called properties! In this talk, we'll check out how properties in Kotlin make coding easier and more fun, especially when compared to Java. We'll break down the idea of property delegation, showing how it helps simplify code and keep things neat. Plus, get ready for a hands-on example that proves how this delegation thing can solve real-world problems. Whether you're a Kotlin whiz or a fan of Java, this talk is all about making sense of the magic in Kotlin's properties.
