@maven.apache.org 4 (from 4.0.0-rc4 on) contains the Maven Upgrade Tool with which you can automatically upgrade your Maven project. I finally found time to write a small article about it's feature and how to use it. Please test the tool and give feedback :)

Additional transformers for the Maven shade plugin dealing with GraalVM native image configuration files. - michael-simons/native-image-config-transformer

I have created a thing with #Java that I needed for #Maven and #GraalVM so that I can provide fat-jars (needed for tools that don't do dependency management) that don't behave different in #NativeImage than our normal distributions:

Maybe this is helpful for others, too.

It's as old as Perl.

Biggest mistake in software dev: Designing a UI without the people who are going to use it (aka the end user).

Why doesn't @bsky.app have an "Add to list" button?

Started a new project with @jetbrains.com's Ktor. Much better experience than the last try. Documentation nowadays is top notch, lots of examples, lots of integrations with common technologies.

Server starts in 200ms, and it's just code. No annotations, no metaprogramming, just plain old Kotlin.

Ktor 3.2.0 Is Now Available | The Kotlin Blog Ktor 3.2.0 is here! This release brings exciting new features, performance improvements, and bug fixes.

🚀 Ktor 3.2.0 is out, bringing new features and performance improvements!

Woohoo! When we evaluated Spring Data JDBC a few years ago this was a huge blocker. Time to reevaluate!

Very cool idea!

Man ist noch nicht mal sonderlich überrascht.

Man möchte mit der @deutschebahn.com zu einen Spieleabend fahren, und natürlich schafft man nur eine Haltestelle bevor der Zug einen rauswirft. Bei 33 Grad ohne Wasser. Der vermeintliche Anschlusszug hat immer 15 min Verspätung. Auch 15 Minuten später. Typisches Bahnerlebnis.

went to a few #DevoxxPL talks this morning and so far every single speaker, myself included, recommends using @sdkman.io. well deserved!❤️

#rant of the day: If using inline value classes in Kotlin name the wrapped primitive `value` and don't give it the same name as the value class.

value class Name(name: String) ❎
value class Name(value: String) ✅

println(name.name) 😔
println(name.value) 😌

Portability is a feature, and not all projects need it.

Instead of preparing for a future that might never come (switching the DB that the bank has been using for 20 years), you are better off getting the most out of your current technology stack.

In almost all Spring Data JPA projects I see people annotating their JPA Repositories with @Repository. But why? It's not needed, and the interface name should be a good enough hint already.

I wish @junit.org would somehow hint that expected and got are different types. Always trips me up.

version
Expected: 1
got: 1

How I take work notes as a developer I’m kind of a notes geek and wanted to share what kind of notes I keep and why when I work in software development.

TIL: While using #SpringBoot with #Kotlin, you can assign default value to request parameter using Kotlin's default value feature without using "defaultValue" attribute.

Yep, it was commited 1 hour ago, so the next nightly of @shipilev.bsky.social will have it, or the next EA with @sdkman.io :)

#Java 25 is shaping up to be another BIG release! 🚀 Currently targeted final features:

* simplified main
* flexible constructors
* module imports
* scoped values API
* key derivation function API
* compact object headers

Compact object headers will already become stable!? Nice!

Will it also work outside of Azure?
