ABOUT THE TALKS
Runtime Configuration Updates with Spring Boot (Joris Kuipers)
Spring Boot applications provide rich abstractions for working with various property sources to configure your applications. Most applications will only read their configuration at startup and require restarts to pick up any changes. However, it doesn’t have to be this way! In this session, we will learn about Spring’s support for dynamically picking up changes in external configurations, so that you don’t need restarts anymore.

From DevEx Disaster to Delight: How to Champion a DevEx Revolution in Your Organization (Jeremy Meiss)
Is your development team struggling with bugs, inefficient tools, and demoralizing processes? Do you often hear your developers expressing their frustration with the deployment process and the codebase? Don't worry, this talk is your ticket to transforming your organization's Developer Experience (DevEx) from a disaster zone to a developer utopia. Join us for a session filled with humor and insights that will equip you with the tools to improve your team's productivity and satisfaction.

Count-Min Sketch, Bloom Filter, TopK: Efficient probabilistic data structures (Raphael de Lio)
A Count-Min Sketch, a Bloom Filter, and a TopK might sound fancy, but they’re just smart ways to work with huge amounts of data using very little memory. In this talk, we’ll explore three powerful probabilistic data structures that trade a bit of accuracy for a lot of speed and scalability. By the end, you’ll see how these tools help you process large data streams without blowing up your memory, and how to apply them in real-world systems where being fast matters more than being perfect.

AI-Powered Productivity in the Development Lifecycle (Jonathan Vila)
In the current software development context, staying updated is essential, and that means using Artificial Intelligence (AI), particularly Code Generative AI. It is changing the way developers work, offering never-seen productivity improvements throughout the entire development life cycle. This talk will go into the practical applications of AI-powered tools and methodologies focused on software development. This talk will showcase practical tools and strategies to integrate AI into your development workflows, increasing productivity and efficiency levels.
In this meetup, in addition to food, drinks, and networking, you will experience four excellent talks of approximately 30 minutes each:
