I was developing an HTTP filter in Micronaut to add post-processing on the HTTP server response.

In my IDE I wrote `@ServletFilter` instead of `@ServerFilter` 🤦 ... what does it say about me?

Je viens justement de lire un article qui parle de ça: utkarshkanwat.com/writing/bett...

Et je viens aussi d'en discuter avec ma product manager car on prépare des choses du côté des Agent IA pour Kestra 1.0!

I was so eager to have named parameter that I mis-read named constructor to named parameters ;)

Named constructor is just a fancy static factory method right? Nothing exciting IMHO.

Named parameters in constructor and method is one of the most desired features in #java...

First time I see bogus parameter used in such area but it should not be that rare I guess :(

We just published a new JEP Draft for "Post-Quantum Hybrid Key Exhange for TLS 1.3". This will build on the post-quantum ML-KEM implementation in JDK 24 (JEP 496) and is another significant step in protecting your Java applications from future large-scale quantum computers.

"Social media users are tired of losing their identity and data every time a platform shuts down or pivots. In the ATProto ecosystem, users own their data and identities. Bluesky is the first big example, but a new wave of decentralized social networks is just beginning."

Kestra Open Source has Just Reached 20,000 Stars Orchestration should be simple, powerful, accessible to everyone, and open-source.

🚀 20,000 stars on #GitHub

Kestra started with a simple idea:
Orchestration shouldn’t get in the way.
No infra hurdles. No DSL lock-in. No black boxes.

Just open-source, accessible, powerful automation built with you, for you.

Thank you.

C'est une question pertinente d'un grand intérêt!

Est-ce que l'arrivée des IA de code risque de ralentir l'innovation dans les langages car les IA ne connaîtront pas par nature les nouveauté d'un langage ou un nouveau langage en lui-même?

Retrieval Augmented Generation (RAG) with Google Gemini AI and Langchain4J Create a Retrieval Augmented Generation pipeline with Google Gemini AI and the Langchain4J plugin.

🧠 Build smarter GenAI workflows with Google #Gemini + langchain4j all in Kestra.

RAG = Real context. Fewer hallucinations.

Ingest docs ➡️ Embed ➡️ Retrieve ➡️ Generate fully automated, AI-provider agnostic.

Has this community been abandoned? · Issue #562 · reactive-streams/reactive-streams-jvm Reactive Streams Specification for the JVM. Contribute to reactive-streams/reactive-streams-jvm development by creating an account on GitHub.

When people explain me that Reactive Streams is the standard, and not java.util.concurrent.Flow, well... github.com/reactive-str...

Reactive Streams as a project is dead folks. No one maintains it, and no one is even able to make any release (see github.com/reactive-str...).

Get over it.

How do you deal with the API size?

We have that also for @kestra.io but the size of the API easily lead to issues with the LLM context windows.

Thombstone with "RIP Applet" written on it.

RIP Java Applets. You made Java popular and helped it grow to what it is today.

JEP 504: Remove the Applet API has been proposed to target (openjdk.org/jeps/504), so there will be no more applets with the next JDK (JDK 26).

Gravitee: API Documentation at the Click of a Button Thanks to Kestra Discover how Gravitee automates API documentation using Kestra's orchestration engine and generative AI — from SQL triggers to LLM-powered content.

Last week we shared how Gravitee now generates API docs with a single click.

But what powers that feature?

A smart, AI-powered pipeline fully orchestrated in Kestra
