    Are you really wasting your time in Java without these 10 libraries?

    A critical analysis of 10 commonly recommended Java libraries, evaluating their current relevance and usefulness. The author argues that some popular tools like Lombok and MapStruct are no longer necessary given modern Java features and alternatives like Kotlin, while others like Liquibase/Flyway remain essential for production deployments. The piece emphasizes context-dependent decision-making over blindly following listicles, noting that tools like SLF4J, Jackson, JUnit, and Spring remain valuable, while Apache Commons Lang and Guava have diminished utility in modern Java versions.

    Understanding concepts in Event Driven Architectures (EDA)

    Event Driven Architecture (EDA) is a popular choice for developing highly scalable distributed systems, where components communicate by sending and reacting to events asynchronously. Key components include event producers, message brokers, and event consumers. Common technologies used are Kafka, RabbitMQ, AWS SNS/SQS, and Google Pub/Sub. EDA offers advantages such as scalability, flexibility, and resilience, but also has challenges like eventual consistency and complex debugging.

    Introduction to Jimmer ORM

    Jimmer ORM is a new database framework that differs from JPA by requiring developers to specify data interaction details at the call site rather than through annotations. It uses interfaces as entities and relies heavily on DTOs for both reading and writing data. The framework includes a dedicated DTO language to reduce manual DTO creation overhead and supports multiple databases including MySQL, PostgreSQL, and Oracle. Unlike Hibernate, Jimmer doesn't implement dirty checking or traditional lazy loading, instead focusing on explicit data shape specification through DTOs and Object Fetcher APIs.

    Cleaning Spring Properties Files

    Spring Properties Cleaner is a Maven plugin that automatically cleans up Spring application properties files by removing duplicates, standardizing formatting, sorting keys, and extracting common properties across multiple profile-specific files. The plugin can be configured to detect issues during builds, sort properties in clustered or alphabetical order, inline prefixes for better commonality extraction, and manage vertical whitespace. It supports three extraction modes (full, consistent, multiple) for promoting properties to a common application.properties file, helping maintain cleaner and more organized configuration files in Spring projects.

    OpenFeign vs WebClient: How to Choose a REST Client for Your Spring Boot Project

    OpenFeign and WebClient are two popular REST client options for Spring Boot applications. OpenFeign offers a declarative approach using annotated interfaces, integrates seamlessly with Spring Cloud components, and works well for synchronous microservice communication. WebClient provides a reactive, non-blocking HTTP client with fluent API design, better suited for high-throughput applications and reactive programming models. The choice depends on your architecture: use OpenFeign for traditional Spring Cloud microservices prioritizing simplicity, and WebClient for reactive applications requiring high performance and concurrent request handling.

    Java or Python for building agents?

    Choosing between Java and Python for AI agents should depend on your team's existing expertise and technology stack, not trends. While Python dominates AI development due to its accessibility and rich ecosystem, Java developers can build equally effective agents using frameworks like Embabel. Organizations will achieve faster AI adoption by leveraging their current tools and skills rather than switching to unfamiliar technologies. By 2028, 80% of generative AI applications will be built on existing data management platforms, reinforcing the value of working with what you already have.

    Spring gRPC Next Steps for 1.0.0

    Spring gRPC 1.0 will support Spring Boot 4.0 as a standalone project rather than being merged into Spring Boot 4.0 as originally planned. The autoconfiguration merge is now targeted for Spring Boot 4.1. Users can upgrade from version 0.12.0 by simply changing the version number in their dependency management, with minimal code changes required. The autoconfiguration and starter dependencies will be deprecated immediately upon release to signal the planned migration to Spring Boot 4.1, though this deprecation is purely about dependency coordinate changes.
