Hexagonal Architecture might be proposed to solve the problems back in the days. But that is completely unnecessary and I would even say overkill for most of the applications. All the driver side, driven side, port, adapter, etc is just more buzzwords describing decoupling the implementation using programming-to-interfaces technique. Nothing more, nothing less. I took one of the Hexagonal Architecture implementation of a Spring Boot app github.com/sivaprasadreddy/h… Created the same application using simple layered architecture (layered-app module) and yet achieve the goals: * Separation of the concerns ✅ * Testability ✅ * Less code, more readable & to the point 🎯 * No unnecessary interfaces with only one implementation 🚫 * No InMemory implementations just for satisfying imaginary testing/local_dev requirements. Use Testcontainers to test with what actual DB you use in production. 🚫 * Made the Service layer as transactional boundary as it should be. ☑️ Stop cargo-cult programming.

Deploying a high load application to production with @java 25 it's a nice way to start the day. #StartMigrationToJava25 #Java25 #Java

OpenJDK PR with significant improvements to sorting implementation: "* introduced Radix in parallel sorting which shows several times performance boost and has linear complexity instead of n*ln(n) * improved mixed insertion sort * improved merging sort for almost sorted data..."

No one wants to program in a dynamically typed language. No one says, "I want this string variable to hold a string an integer now". Hold your defense of Python and JS — read on. I'll explain why dynamically typed languages exist, what they're good for, and why they're still here

Thanks @speakjava for the photo. Such an incredible opportunity to meet in person people you learned a lot from.

Here we go again. One year later I’m here again, but this time with my friend @vincese . #Devoxx

If you are working in a Spring Boot application, please, when you add a new dependency, think if it’s necessary to set dependency’s version or it’s already managed by Spring Boot.

People doesn’t think too much about the cost of creating instances of java.time.format.DateTimeFormatter, and the worst thing is that is a thread safe class. 🤦🏻‍♂️

Sorry, all you many fans of java.util.Date, but since Java refuses to deprecate it, we're deprecating it in Jakarta Persistence. in.relation.to/2024/04/22/st…

This is what I imagine doing large renames like in a language without static typing

It’s sad, but #devoxx has finished, I hope I will be able to come back soon, I enjoyed it a lot. Last talk of the day, by @BrianGoetz, has shown us great possible features that would be added to Java in the future

Today I had the opportunity to greet in person @AdamBien who influenced me a lot in my early days as a java developer, and he still it does. Thanks for the great talk and gotten a lot of ideas 😊🙌🏻 #devoxx

The best way to star the day, learning being more productive with @intellijidea by the great @heinzkabutz #devoxx
