Java Champion Josh Long on Spring Framework 6 and Spring Boot 3

Microservices show where Java lags behind other languages. Reactive programming provides a concise DSL to express the movement of state and to write concurrent, multithreaded code with better scaling. Developing in Spring Boot works well even without special tooling support. Josh Long is excited about Project Loom, Java optimization in Project Leyden, and Foreign-Function access in Project Panama.

Separation of Concerns in Node.js

In Node.js you can structure your code however you want. There is no "correct way". You have the option of writing all of your code in a single app.js file or creating multiple files and placing them in different folders. Most developers, however, would recommend structuring your projects by grouping related data together rather than having it all together.

Moving Kafka and Debezium to Kubernetes Using Strimzi - the GitOps Way

Deploying an Apache Kafka cluster to a Kubernetes is not an easy task. There are a lot of pieces to configure like the zookeeper, the Kafka cluster, topics, and users. Strimzi is a Kubernetes controller making the deployment process of Kafka a child game. Moreover, Strimzi lets you manage Kafka using GitOps methodology as everything is executed using a Kubernetes YAML file.

Virtual Threads: New Foundations for High-Scale Java Applications

Virtual threads are a lightweight implementation of Java threads, delivered as a preview feature in Java 19. They dramatically reduce the effort of writing, maintaining, and observing high-throughput concurrent applications. Virtual threads breathe new life into the familiar thread-per-request style of programming, allowing it to scale with near-optimal hardware utilization.
