Helsinki Java User Group 2023.11 meetup @ Wolt

Welcome to the 10th meetup of Helsinki Java User Group!

This time we're hosted by Wolt.
There will be talks, discussions, and snacks.

We'll have two talks:
1. "Deep Dive into Completable Future" by Dr. Venkat Subramaniam (award-winning author, founder of Agile Developer, Inc., and an instructional professor at the University of Houston)

Have you looked at the methods of CompletableFuture and wondered how to actually use them? Do the function names appears strange or at least different from what we're used to. Let's take another look so those names become easier to remember and also to make use of.
In this presentation we will take a practical look at CompletableFuture and how to make good use of it, and how to deal with exceptions.

2. "How JVM observability works: magic behind APM instrumentation libraries" by Oleksandr Kachur (Software Engineer at Wolt, high priest in the Church of JVM)

Explore the dynamic realm of Java APM libraries shedding light on how it works under the hood enhancing monitoring capabilities of JVM based applications. Uncover the pivotal role of Java agents in current state of JVM observability and how it supercharges wide range of tools: from code coverage libraries to observability platforms like DataDog and Elastic. Elevate your understanding of Java's performance landscape through this insightful exploration. Let's unravel the magic of JVM APM libs and Java agents!
