Quarkus started in development (quarkus:dev) mode with a JAX-RS endpoint exposed, opens two ports: (http) 8080 and (debug) 5005 per default.

You will have to assign distinct ports for every new launched instance. The http port is configurable in the application.properties: quarkus.http.port=8282 or environment entries (not suitable for our purpose), the debug port can be changed (-Ddebug=6000) or deactivated from the command line only: mvn compile -Ddebug=false quarkus:dev

Building a Java backend service with familiar APIs on a next generation runtime:

The very first airhacks.tv 2021 episode with the following topics:

"Vanilla Web Components in 2021, MicroProfile vs. Jakarta EE, authentication and authorization, Java monoliths vs. microservices, hazelcast, bulkheads and executor services, the role of patterns, popularity of NetBeans, SpringBoot on Quarkus"

The default Visual Studio Code configuration for autocompletion of ES 6 imports "javascript.preferences.importModuleSpecifierEnding" is set to "auto" and is therefore unpredictable.

With the change to: "javascript.preferences.importModuleSpecifierEnding":"js" Visual Studio Code generates valid ES 6 imports. This is particular useful in vanilla Web Component applications:

Topics and questions for the very first airhacks.tv in 2021:

• The role of vanilla WebComponents in 2021
• Java, MicroProfile, Jakarta EE in 2021
• Authentication and authorization with Gluu or Keycloak
• Jakarta EE 8 monoliths and Hazelcast on Payara vs. microservices
• Creating managed executor services programmatically in GlassFish / Payara

This snippet generates an endless / limited (to ten in this example) list of booleans:

import java.util.stream.Stream;
import java.util.stream.Collectors;

//...
var randomBooleans = Stream.
                    generate(Math::random).
                    limit(10).
                    map(r -> r > 0.5).
                    collect(Collectors.toList());

System.out.println(randomBooleans);

...or (thanks to @RUAmentalist):

import java.util.Random;
//...
var randomBooleans = new Random().
                    ints(10).
                    mapToObj(r -> r > 0.5).
                    collect(Collectors.toList());
System.out.println(randomBooleans);

Prints: [true, false, true, false, false.... The output should be different each time :-)
