134th airhacks.tv: gRPC vs. REST, Quarkus, AI, Performance, Vector DBs--134th airhacks.tv 📎

The 2025.05 / 134th edition of airhacks.tv with the following topics:
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

JavaOne,JavaLand, GenAI, Langchain4J, Lombok, Rolling Updates, Sync/Async, Serverless--133rd airhacks.tv 📎

The 2025.04 / 133rd edition of airhacks.tv with the following topics:
"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"

JavaOne 2025 Afterglow / Conference Recap 📎

  1. Convenient and nice location: all sessions were in one building - there was enough time to walk between sessions, have a hallway conversation ...and get a coffee.
  2. Speaking of coffee, the standard coffee was good and much better than in the hotel. And great Italian speciality coffees were served by passionate San Francisco baristas. I had my first Cortado at JavaOne.
  3. Excellent presentations by core Java/Oracle engineers. They were well prepared with great content. Talking to (former) Oracle engineers / Java committers has always been my main motivation for attending JavaOne.
  4. Good (great?) food, (too) good local biscuits. Always plenty of drinks and coffee.
  5. Great attention to detail: useful gifts, nice stickers, JavaOne branded seat cushions, Java coasters, JavaOne signposts, badge flags and posters.
  6. Good party venues: the food was good, the venues were nice, and it was easy to make conversation.
  7. JavaOne was also better attended than expected.
  8. Perfect organisation: from the badge to the schedule to the conference app, everything worked perfectly.

I was surprised by the quality of the conference and started asking attendees about their experiences. The answers were all positive.

The most surprising fact was that the majority of people were attending JavaOne for the first time. I asked during my presentation - more than 70% had never been to JavaOne before.

It is hard to find anything that could be improved, other than the size of the rooms. The rooms were either too big or too small. There was a lack of medium sized rooms. I also missed the evening BoF sessions, but my schedule was already packed.

In the event that my proposal is accepted - see you again in the year 2026

Service Discovery, J2EE to Quarkus, AWS Lambda, System Testing, CI/CD and JFRs--132nd airhacks.tv 📎

The 2025.03 / 132nd edition of airhacks.tv with the following topics:
" J2EE to Quarkus migration can save around 50% memory for on-premise deployments, EJBs are straightforward to migrate but MDBs with two-phase commit are challenging, Change Data Capture like Debezium is an elegant solution for transaction handling, Running JFR all the time in production is a best practice for on-premise deployments, CryoStat provides visualization for JFR events in OpenShift, Quarkus binary executables work well for AWS Lambda but require managing your own runtime, Using AWS-managed Corretto runtime is advantageous for security patching, Application Load Balancer can route to both Fargate and Lambda behind the same URI, Function URL is the cheapest way to run Lambda but HTTP API Gateway provides nicer URIs, Monolithic applications are still valuable when well-structured, Modern Java with records can make JDBC more appealing than ORMs for complex queries, Cloud provider migration is less about Java code and more about mapping equivalent services, System testing should be done by deploying applications to production-like environments and testing them functionally."
