Java 26 released

Java 26 delivers thousands of improvements that boost developer productivity, simplify the language, and help developers integrate AI and cryptography functionality into their applications. To help developers further streamline and enhance their development initiatives, Oracle is also announcing the new Java Verified Portfolio, which provides developers with a curated set of Oracle-supported tools, framew

Most Java CLI tools stop at mvn compile exec:java.

That works locally. It doesn’t scale.

In this guide I show how to:
- build a fat JAR
- automate GitHub releases
- publish a JBang catalog
- install with one command

No cloning. No Maven required.

@javapro Skipping #Java events because of the „AI“ trends on your slop-generated image.

Thanks to all the #DevNexus folks who attended my #Java talk on #Refactoring in #IntelliJIDEA (mostly) without AI.

Slides are available here: https://ted.dev/talks/#past-talks

Want this talk (or other ones) at your group event or conference, let me know!

This year #IntelliJIDEA turned 25! It continues to evolve over the years, adding new features, integrating with tools and frameworks, etc.

This documentary shows the history of our favorite #Java & #Kotlin IDE and the company and people behind it.

Hey #DevNexus!

Want to learn some Old Skool #Java refactoring techniques in #IntelliJIDEA? It can be faster, more reliable (and cheaper) than using LLMs to do all the work. It's also a great way to learn a new codebase, including LLM gen'ed code.

Join me at 2:50pm in room 302!

#Spring #Java

Аудитор: Человеко-Ориентированный Трекер Эволюции Библиотек

Java принято называть языком программирования, но по сути это целая программная система, включающая три уровня: формальную верификацию модели через теорию типов, среду выполнения с динамическим линковщиком JVM и ментальную модель, которую разработчик выстраивает вокруг библиотек. Когда автор меняет сигнатуру метода, страдает не только байт-код — рушится контракт и привычное представление о стабильности API. Существующие инструменты проверяют бинарную и исходную совместимость, но их ответ сводится к вопросу «упадёт или не упадёт». При этом они не объясняют суть изменений: например, если метод перенесли из подкласса в суперкласс, анализатор покажет «удалено в А, добавлено в Б» — технически верно, но по смыслу ничего не объясняет. Здесь нужен человеко-ориентированный подход . Библиотеки — такие же продукты, как и любые другие, и их потребители заслуживают внятного объяснения того, как эволюционирует API. Предлагаемый инструмент — Аудитор — умеет не только проверять совместимость, но и распознавать рефакторинги по их смыслу: отслеживать перемещение методов по иерархии, выявлять смену ответственности между классами, обнаруживать паттерны изменений. Вместо сухого списка «добавлено/удалено» он генерирует человеко-читаемые отчёты на вики-страницах проекта, где разработчик видит не просто факты, а историю эволюции структуры API. Это сохраняет актуальность ментальной модели библиотеки и снижает риск неверной интерпретации изменений при обновлении версий. В статье будут рассмотрены нюансы каждого из 3х уровней, чтобы дать теоретические основы, необходимые для понятия бинарной и исходной совместимостей версий (binary & source compatibility), а также же представлен практический обзор на новый фреймворк, написанный мною, для их автоматического аудита на вики-страницах, которые станут прекрасным дополнением к вашим Java проектам.

Architecture diagrams don’t stop bad dependencies.
Code reviews don’t scale.
Conventions fade over time.

What does work: executable architecture rules.

I wrote a hands-on guide showing how to use Quarkus + Taikai to turn architectural decisions into tests that fail the build when boundaries are violated.

If you care about keeping Java codebases understandable over time, this one’s for you.

Seeking advice for FreeBSD as a daily driver on an ASUS X580VD

(Intel HD 630 + GTX 1050 Optimus)

Five questions at <https://www.reddit.com/r/freebsd/comments/1r9j67j/advice_for_running_freebsd_as_daily_driver_on_an/> (replies there, if you can – thanks).

The writer's use case and goals:

― web dev stack: Java, Node/React, Python, Go

― occasional virtualization and Linuxulator for Linux-only tooling

― prefer GNOME, but open to recommendations if another DE/DM is more reliable here

― Intel as primary + NVIDIA for on-demand/offload use (if possible).

Notes from Wednesday's live coding #Java stream are now up.

In addition to doing some coding, I looked at #EventModeling diagramming tools from Daniel Ranner's "Slicr" and Ismael Celis' "https://EventLanes.app". Love text-to-diagram tools like these!

https://ted.dev/articles/2026/02/18/live-coding-journal-feb-18-2026/

So the bad news is that none of my #Java talks got accepted at Devoxx UK.

The good news is that means I can go to ComoCamp in Vienna and just purchased my ticket!

I'm very excited as I love collaborative modeling and love participating in unconferences! https://comocamp.org/
