Wie viel digitale oder reale Gewalt sind Mitglieder und AnhΓ€nger der AfD bereit anzuwenden um ihre verfassungsfeindlichen Ziele gegen mich und mein Tram umzusetzen? Staatsschutz ist besorgt. Der Rechtsstaat wird herausgefordert, wenn Urteil nicht durch Berufung, sondern Bedrohung angefochten werden.

I built a full #Quarkus app that loads an image, runs it through #ImageMagick, and returns a polaroid β€” all through the Foreign Function & Memory API in JDK 25.

If you’re curious how #Java taps into the same native performance Python relies on, this is for you.

Non-null variable declaration in Java using instanceof patterns Ever since JRuby 10 upgraded to Java 21, I’ve been re-learning Java with all the excellent language enhancements of the past decade. One of my favorites has to be the instanceof pattern matching…

Why not use Java's instanceof patterns to null-check values in the middle of an `if` statement?

Yesterday realized that writing a number of tests for YAML/JSON (reading/writing) via Jackson a few months ago was a very good decision. It helped to find a few issues related to the upgrade to Jackson 3 (configuration/default behaviour etc.).

#apachemina using sshd Stumbled upon this. Using net.i2p.crypto:eddsa:0.3.0 running three hosts; executing a couple of commands via sshclient: takes ca. 1.75 seconds using another provider org.bouncycastle:bcpkix-jdk18on the same executiong takes ca. 2.4 seconds ? What the heck?

Help--my LocalDate isn’t flattened! Just before my Valhalla talk at JFall, I found out that the early access build can flatten LocalDate arrays, but the latest version from Github cannot. Why? Serialization, of course. Read the gory details at https://horstmann.com/un...

The talk Brian Clozel and I gave at #Devoxx is already online.

Always great to share the stage with Brian. We covered what’s next for Spring Boot: API versioning, resiliency, OpenTelemetry, structured concurrency, and more.

All you need to do for #Eclipse is configure the #jSpecify annotations into the null-checking capabilities that have existed for ages.

Spring Boot 4.0.0-M2 introduces a null-safe API thanks to JSpecify πŸŽ‰ Try it with IntelliJ IDEA, Kotlin, or checkers like NullAway and share your feedback.

I hope somebody will contribute JSpecify support to VSCode and Eclipse 🀞
