The example uses the embedded Spring Boot Keycloak Server to quickly spin up a new Keycloak instance.

Create JBang script with

jbang init spring-keycloak-server

Adapt spring-keycloak-server script.

Run the Keycloak server via:

linux-china

///usr/bin/env jbang "$0" "$@" ; exit $?
//DEPS io.netty.incubator:netty-incubator-transport-native-io_uring:0.0.5.Final:linux-x86_64

import io.netty.incubator.channel.uring.IOUring;

public class HelloIoUring {
    public static void main(String[] args) {
        IOUring.ensureAvailability();
        System.out.println("Hello io_uring!");
    }

Describing Kafka schema usage using AsyncAPI

I've picked a dozen scenarios to illustrate the range of things that I think AsyncAPI needs to be able to describe. My goal is to have enough information in the AsyncAPI spec for a developer writing an app to consume messages from the topic.

Motivation

Integrate JMH (Java Microbenchmarking Harness) with Spring (Boot) and make developing and running benchmarks as easy and convinent as writing tests.

Idea

Wrap the necessary JMH boilerplate code within JUnit to benefit from all the existing test infrastructure Spring (Boot) provides. It should be as easy and convinent to write benchmarks as it is to write tests.

TL;DR;

Simple Program that prints the Speed of Light in meters per second. Coded by Pedro.

public class SpeedOfLight {

    public static void main(String[] args) {
        //I have used an integer because the needed value fits the range of an integer. I have not used a DataType wrapper here to keep it simple.
        int sol = 299792458;

        // Prints "The light speed is ... m/s" to the terminal window.
