Native compilation of Java applications with GraalVM
Java applications are known for their relatively high memory usage and slow startup time. In a cloud environment, this can lead to unnecessary costs. The GraalVM JDK distribution addresses these issues with the ability to compile Java applications ahead-of-time to native code. In this presentation you will learn how this works and you will get a demo of a compiled Spring Boot 3.0 application with reduced boot time and memory usage.

About Joris Giesen - Software Engineer - Craftsmen
A modest all-rounder. He is currently working for Atradius as an Architect / Software Engineer where a new platform is being designed and built - from scratch. In his spare time you will find Joris in the gym to stay healthy & in shape ;-).

About Remco Weekers - Software Engineer - Craftsmen
Remco is an enthusiastic full-stack software engineer. With a preference for backend. Remco is currently developing a microservice landscape on a stack with Spring Boot at the Dutch tax authorities. And as if his work isn't challenged enough already, Remco also likes to keep up with innovations, and to try out new things in online puzzle assignments and (for example Reactive Programming) hobby projects.

Reading code
As developers, we spend a lot of time learning to write code, while spending little to no time learning to read code. Meanwhile, we often spend more time reading code than actually writing it. Shouldn’t we be spending at least the same amount of time and effort improving this skill? Deliberate practice can help us get better at reading code. Learning how to better read and understand code, can in turn teach us what makes code readable. This might even help us to write code that is easier to read.

In this talk we will discuss the benefits of deliberately practicing reading code in a code reading club or session without an IDE, as well as common strategies to navigate a new codebase and familiarise ourselves with the code using the IDE.
