JHipster
JHipster, much like Spring initializr, is a generator to create a boilerplate backend application, but also with an integrated front end implementation in React, Vue or Angular. In their own words, it "Is a development platform to quickly generate, develop, & deploy modern web applications & microservice architectures."
exports.onExecutePostLogin = async (event, api) => { const namespace = 'https://www.jhipster.tech'; if (event.authorization) { api.idToken.setCustomClaim('preferred_username', event.user.email); api.idToken.setCustomClaim(`${namespace}/roles`, event.authorization.roles); api.accessToken.setCustomClaim(`${namespace}/roles`, event.authorization.roles); } }

Project mention: 2023 will be when browsers will support GC-based languages in production. Both GC and Exception Handling are already available to various degrees. Being an early adopter could boost Scala's adoption by being one of the first but also the best language in the browser! | reddit.com/r/scala | 2023-02-02
GraalVM's Native Image is pretty wonderful, and I'm sure it will end up supporting WASM; just like in the case of Scala Native, this will take some wind away from any other WASM effort; and speaking of optimizations, GraalVM has more resources to invest in an AOT compiler that can do optimizations ahead of time. And because of the “serverless” trend, the community has invested significant resources into native-image resources already. The existence of developments like Quarkus or Spring Boot 3 can only mean that build tools and libraries ready for Native Image will only get better.

Project mention: Analysing Github Stars - Extracting and analyzing data from Github using Apache NiFi®, Apache Kafka® and Apache Druid® | dev.to | 2023-01-11
You can install Kafka from https://kafka.apache.org/quickstart. Because Druid and Kafka both use Apache Zookeeper, I opted to use the Zookeeper deployment that comes with Druid, so didn’t start it with Kafka. Once running, I created two topics for me to post the data into, and for Druid to ingest from:

The Java API implementation is problematic due to over allocating which results in a great deal of overhead. Projects like QuestDB don't use the Java API much to reduce GC thrashing. It results in a DB that outperforms C++ counterparts.

Testcontainers
Testcontainers is a Java library that supports JUnit tests, providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.
Project mention: Spring Cloud Gateway 4.0.0-RC2 native example with Testcontainers | dev.to | 2022-12-08This repository provides a BuildImageTest that uses the buildpack to create a native image. It then tests the native image, using Testcontainers and JUnit. Building the native image with AOT processing, as part of a test, takes minutes not seconds, and should not be part of normal "inner loop" development. So the BuildImageTest is in a separate sourceSet and can be executed independently. This is a very powerful pattern, that I'm just getting started with. I would love to hear your thoughts on this pattern or other alternatives to it.

Graylog is an open-source centralized log management and analytics tool. It collects, enhances, correlates, searches, and visualizes all your log data in one location to uncover patterns and trends for application and IT infrastructure.

I looked in LivingEntity and it looked to me like water movement physics are still hardcoded to affect all non-lava fluids in the travel function. https://github.com/MinecraftForge/MinecraftForge/issues/8608 is listed in the fluid API commit as the go-to source for info and it mentions a "fluid motion" setting but I don't see it. I get the feeling the documentation is outdated but that's literally the only documentation I can find anywhere about this api. Very frustrating.

IMHO you're better off using something like https://www.drools.org/ for this. Non-devs writing code is a pipe-dream. It never works out.
