Câu chuyện refactor ứng dụng Java của PVS-Studio: Từ code rối rắm với static methods, Singletons, đến tích hợp DI bằng Guice, làm sạch style theo Google Java Style, và xây dựng module annotation mới hỗ trợ taint analysis & JSON user-defined. Kiến trúc modular, dễ mở rộng hơn!

#Agile vs. Wasserfall? Diese Debatte bringt uns nicht weiter. Marin Niehues analysiert, wann welche Methode wirkt & wieso Haltung, Struktur & Feedback den Unterschied machen.

Ok, by now I do fail to understand this. Post one from September 15th:

> GraalVM for JDK 24 was the final GraalVM release licensed and supported as part of Oracle Java SE Products.

https://blogs.oracle.com/java/post/detaching-graalvm-from-the-java-ecosystem-train

Yesterday, September 16th, #GraalVM Community Edition 25 is released:

> GraalVM Community Edition 25 based on OpenJDK 25

respectively

> Oracle GraalVM 25 based on Oracle JDK 25.

https://www.graalvm.org/release-notes/JDK_25/

Is that written by the same layers who also wrote what an LTS of #Java is or wat?

Java 25 LTS is here! 🚀 Ready to tap into the latest #Java features? #IntelliJIDEA supports Java 25 from day one. Let’s dive into what’s new and how your IDE has you covered! 👇
https://blog.jetbrains.com/idea/2025/09/java-25-lts-and-intellij-idea/

Finally created a page that will have all of my talks (yes, they're all Ted Talks 😂): https://ted.dev/talks/

Right now it has the #Java talks I'm giving at Commit Your Code on September 25th, and at dev2next on October 2nd.

Soon it'll have past talks with slides, code, etc.

Watching the #Java #Java25 #release stream with friends @DJGummikuh @FrVaBe @oli 👋 @nipafx @ammbra1508 @Sharat_Chander

Also seeing Dr. Depracator @stuartmarks fries are in the making ofc 😅

Gotta wake up early here on the West Coast for the #Java 25 release live stream on Sept 16!

Join the Java developer relations team (and some special guests, such as me!) to find out what's in #JDK25, what's new since JDK 21, and what's coming in 2026.

I created a toy #Java project using #JSpecify

This is what you can express (among others):

https://codeberg.org/michael-simons/javaspektrum/src/commit/14281628ac054dfcaed2c4e3bf951f3329da6b49/jspecify/src/main/java/ac/simons/javaspektrum/jspecify/Calculator.java#L9

One required argument, one optional argument with optional content.

To check it, you need to have #Nullaway https://codeberg.org/michael-simons/javaspektrum/src/commit/14281628ac054dfcaed2c4e3bf951f3329da6b49/jspecify/pom.xml#L319-L341

Build with mvn package -DwithNullaway, to see compile fail (there's test passing null).

Nullaway and modern Java is fun: https://codeberg.org/michael-simons/javaspektrum/src/commit/14281628ac054dfcaed2c4e3bf951f3329da6b49/jspecify/.mvn/jvm.config#L5-L12

Also added #Kotlin code: You can remove the package, and see how it affects what Kotlin sees.

🚀 Java devs, think you know every edge case?

Join author Jeanne Boyarsky on Sept 23 @ 6:30pm for real-world Java "gotchas" from Java 17–25 (and beyond)! Sharpen your instincts & avoid hidden pitfalls.

Is #Agile failing your teams? Maybe it’s not the method—but how you use it. Marin Niehues outlines why context, psychological safety, and clarity matter more than any framework.

#Scrum, #Kanban, SAFe—popular #Frameworks often promise clarity and speed. Yet many teams still face stalled delivery and low trust. Marin Niehues shares insights on why structure alone isn’t enough.

Schöne JUG Mainz mit @sippsack zum Thema Value Objects gehabt. Tolles Thema, freue mich auf das was da kommt.

Was mich auch gefreut hat ist, dass das heute unser erstes Treffen war das wir nicht auf Meetup sondern im Fediverse über Mobilizon angekündigt und geplant haben und mehr Leute da waren als die letzten Male. Lag sicher auch am Thema und an Falk, aber trotzdem schön. Folgt uns auf @jug_mainz um über neue Events informiert zu werden! #mainz #java
