GR8Conf EU 2019 - what can you expect from my talks?

GR8Conf EU 2019 starts precisely in 13 days (on May 27th). Each year Copenhagen becomes a heart of Groovy vibrant community for 3 days. The conference offers both talks and workshops, focused on Groovy related topics such as upcoming Groovy 3 release, building DSLs, using Micronaut in the cloud-native environment, or testing applications with Spock and Geb, to name a few. And that’s not even a quarter of great stuff you can expect from it. This year you can also attend one of my three talks I’m going to deliver.

How to

Installing GraalVM EE 1.0.0-RC14 with SDKMAN!

I love SDKMAN!. It made using multiple different Java distributions in a single operating system much more comfortable. You can install Java across different versions (from 6 to 13.EA) and different vendors (OpenJDK, Oracle, Zulu, Corretto or GraalVM CE to name a few). Switching between those versions is as simple as executing a single sdk use java {version} command and you are ready to use whatever Java you want. However, not all Java versions are available by default, but luckily, SDKMAN! has a simple solution to this problem.

Ratpack on GraalVM - how to start?

The journey inside the exciting world of GraalVM continues. Today I would like to share with you results of running Ratpack on GraalVM experiment. You are going to learn how to build a native binary of a simple "Hello, World!" Ratpack application. In the end we are going to run some benchmarks to see if running GraalVM executable produces better results than running JAR on a regular Oracle JDK.

GraalVM with Groovy and Grape - creating native image of a standalone script

The Apache Groovy programming language has extraordinary scripting capabilities. When you combine it with the Grape dependency management system, it turns out that the sky is the limit. In one of the previous blog posts, I explained how you can start compiling Groovy code to the native binary files, using GraalVM’s native-image compiler. This time I tried to do the same with the Groovy script that uses Grape to provide an external library to the classpath. I thought it won’t be possible, but luckily - I was wrong.

GraalVM and Groovy - how to start?

GraalVM became one of the most popular topics in the JVM ecosystem. It promises the highest possible speed of running JVM-based programs (when compiled to native images), hand in hand with the smaller memory footprint. It sounds interesting enough to give it a try. And today we are going to play around a little bit with running simple Groovy program after compiling to a standalone native image.
