ZB (Zero Dependency Builder) is a simple build tool for Java without external dependencies, Main branch only development works well for most enterprise projects but not when releases are dictated by law, Load balancers like HAProxy and Nginx are recommended for on-premise while cloud load balancers are good for global distribution, JSON-P is a simple way to handle JSON in Java applications, Entity mapping can be done with direct serialization or through DTOs depending on API versioning needs, EJBs can be faster than RequestScoped beans due to object pooling and graph reuse, Quarkus deploys at build time and performs tree shaking for better performance and security, Native images make sense for on-premise deployments but not necessarily for cloud/serverless, AI tools are useful when you can quickly evaluate and accept/reject suggestions, Trunk-based development avoids merge conflicts and keeps the codebase in a functional state, Virtual threads make reactive programming less necessary

and answered questions:

1. Why should you use static method in an interface why not just use a class?
2. How are you using AI tools like copilot or cursor?
3. What is a good load balancer?
4. How would you map in a project that use BCE an entity post from block?
5. How would you do if you want a different request for the creation for the post as well?
6. Would you create the attribute names with static strings?
7. Are you aware of JSON-P being brought into the JDK?
8. Would you like to update the benchmark about request scoped and EJBs?
9. Do you use native images? Why or why not?

Ask questions during the show via twitter mentioning me: https://twitter.com/AdamBien (@AdamBien),using the hashtag: #airhacks or built-in chat at: airhacks.tv. You can join the Q&A session live each first Monday of month, 8 P.M at airhacks.tv

1. Meet zb (zero dependencies builder)
2. Request for recommendations for load balancer tools for on-premise applications, with previous GSLB experience being limited compared to cloud-based solutions and seeking more feature-rich alternatives.
3. Use DTOs like PostDto in the Boundary layer for responses to avoid exposing entire JPA entities, and utilize separate DTOs like CreatePostDto for handling creation requests.
4. Boundary layer manages interaction between application and external systems, handling requests and responses using appropriate DTOs.
5. Managing CI/CD and collaboration with multiple people using only the "main" branch workflow.
6. Comparing RequestScoped and EJB performance in Quarkus, questioning necessity of waiting for "EJB Replacement" for performance optimization.
7. Discussion on whether RequestScoped is currently sufficient without optimizations like pooling and max concurrency that are only available in EJB.
8. Payara's startup and deployment speed now comparable to Quarkus thanks to Project Leyden and JDK 24 improvements.
9. Java's overall performance enhancement with JDK 24 reduces performance gap between Quarkus and other Java frameworks.
10. Project Leyden makes reflection no longer a performance bottleneck, benefiting all Java applications.
11. Introduction of jtaccuino project - a Jupyter notebook written in JavaFX providing an alternative to Python for datascience.
12. time travel, topics form the 35th episode:

    Java EE 8 News, Java SDK for Oracle Bare Metal Cloud Services, Handling JPA relationships in CRUD microservice scenarios, The role of RxJava in typical enterprise applications, JAX-RS returning Response vs objects and JSON vs XML, Cross-field entity validation, GPL/LGPL opensource and commercial projects, What is pac4j.org, Transactions CRUD-Services BCE EntityManager and connection sharing, SCM Managing Structuring and organizing microservices, Gradle adoption gradle vs maven, Dealing with setup scripts in Java EE environment, Oracle JDK vs openJDK and licensing, Greetings from Panama jmoordb, The role of Model Driven Architecture in Java EE

"This interactive session is about practical, no-nonsense coding. We'll explore lean Java 21+ practices and patterns that eliminate bloat and hacks that increase productivity. We will start with structuring and organizing backend monoliths and microservices, cover testing, then move on to decoupling, abstractions, Data Oriented Programming, automation with pure Java."

I used the following example during the session ebank. As a quickstarter for serverless / AWS production projects, I'm using the following template: aws-quarkus-lambda-cdk-plain

REST is about manipulating resources with well-defined HTTP methods (GET, POST, PUT, DELETE) while gRPC is just remote method invocation, Quarkus request-scoped beans are faster than in traditional Java EE due to lack of reflection, Java is 35x faster than Python making it better for AI inference and production, serverless architecture provides cost benefits by paying only for actual usage, RAG (Retrieval Augmented Generation) can be implemented in Quarkus with predefined pipelines, Neo4j works well with LLMs due to its graph structure matching semantic relationships, document categorization with AI can be implemented by passing document chunks to embedding models and using vector databases, Java is getting better with each version with Java 24 being particularly strong, event-driven architecture works well for AI applications by chaining asynchronous operations

See you every first Monday of the month at https://airhacks.tv 8pm CET (UTC+1:00). Show is also announced at: meetup.com/airhacks.

"Treating LLMs as microservices with APIs for enterprise integration, Java is excellent for model inference and production deployment, Enterprise applications benefit from LLMs as decision support tools rather than decision makers, Langchain4j gaining adoption in the Quarkus enterprise space, Java developers and Python developers form distinct groups with different priorities, Future trend toward smaller dedicated models through model distillation, Java's vector API can be as fast as modest GPUs in some cases, Local LLM inference possible with Java at 10 tokens per second, Java 24 released with gatherers and FFM API, Java One conference was well-organized with great content and networking, JavaLand conference focused on community with keynote about 30 years of Java, Centralized logging now standard in cloud environments, Application-scoped services preferred in serverless architectures, Generic utility packages should be avoided for better cohesion, Preference for JSON-P over JSON-B for better versioning capabilities, Synchronous communication preferred over queuing when possible, Vaadin making a comeback with web components support"
