For more details and discussions on the below, go to bit.ly/join-foojay-slack to join the Friends of OpenJDK (Foojay.io) Slack and use the #jug-amsterdam channel for conversations related to the below.

Notes:

• The waiting list has been opened, we've reached maximum capacity between multiple groups where this event has been announced. :-)
• Complimentary parking is available, request a spot by sending a mail to amsterdamjug@googlegroups.com. Parking spots are limited and not guaranteed, first come, first served. Make sure to submit your request at least one week before the event.
• Vegetarian options: we'll make sure that we cater both to vegetarians and non-vegetarians.
• Unfortunately, Jeremy Meiss, who was scheduled to do a talk, can't make it, so there are 3 talks instead of 4 talks below.

In this meetup, in addition to food, drinks, and networking, you will experience four excellent talks of approximately 30 minutes each:

18:00 - Doors Open (And Food!)
19:00 - 19:45 Talk 1: Joris Kuipers — Runtime Configuration Updates with Sping Boot
19:45 Short Break
19:50 - 20:35 Talk 2: Raphael de Lio — Count-Min Sketch, Bloom Filter, TopK: Efficient probabilistic data structures
20:35 Short Break
20:40 - 21:25 Talk 3: Jonathan Vila — AI-Powered Productivity in the Development Lifecycle
21:30 - The End

Abstracts

Runtime Configuration Updates with Sping 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.

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.
