Spring Boot 4 looks amazing 🤩🍃 I have implemented OpenRewrite recipes to automate most of the migration process and handle the major breaking changes. You can run them with the Arconia CLI or using the OpenRewrite Gradle/Mavens plugin. Let me know what you think! I'm planning further improvements.

I have updated my OpenRewrite recipes to upgrade a Spring Boot application to the latest Spring AI 1.1 release. You can run them with the Arconia CLI or via the OpenRewrite Gradle/Maven Plugin. More details: github.com/arconia-io/a... @spring-ai.bsky.social

Wow, this is the first time I make it on the front page of Hacker News! I'm glad so many people are reading my blog post announcing the open-source Java project I've been working on, Arconia, and one the main features: the Dev Services for Spring Boot. www.thomasvitale.com/arconia-dev-...

Java 25 comes with great features and enhancements, including making the language more succinct and beginner-friendly. This is a fully valid Java program. No imports. No method modifiers. No unneeded arguments. And you can run it directly via the "java" CLI. No extra compilation steps. #java

In the latest release of Arconia, I included support for the OpenInference Semantic Conventions for instrumenting your @spring-ai.bsky.social apps and integrating with AI platforms like @arize-phoenix.bsky.social, now available as an Arconia Dev Service for Spring Boot. arconia.io/docs/arconia...

Anthropic (Claude), OpenAI (ChatGPT) and Meta (Llama) have allegedly trained their LLMs on many books illegally, including my book "Cloud Native Spring in Action". We really need open-source LLMs, where both weights and datasets are made available and transparent.

Arconia is a framework I've been building on top of Java and Spring Boot, focusing on developer experience and cloud native. In the latest release, I shipped a new module to integrate with Docling, an open-source, AI-powered, advanced document processor. @jbang.dev makes it really convenient to run!

I'm having troubles using GraalVM from a Nix development environment in VS Code. All other JDK distros work fine. It seems to be just the "graalvm-ce" Nix package to cause issues. I'm not sure if it's a Nix package issue or it's a bug in the VS Code Java extension. Any clue?

Nice overview! Recently, I've been working on OpenTelemetry support for Spring Boot via my Arconia project (not GA yet). It requires one single dependency to enable full observability (logs, metrics, traces), unifying OpenTelemetry and Micrometer. More details here: arconia.io/docs/arconia...

Ollama is a fantastic tool to run and manage large language models locally. And it's now bundled with a nice and clean UI to chat with your local models, including multimodal support for asking questions about your documents ollama.com/blog/new-app

Nix Flakes are great. However, they can only be distributed via Git. I think OCI would be a better distribution format, especially for enterprise use cases. Several startups are working on their own systems to improve Flake usage and distribution, but none of them seem to be considering OCI...

Private, european AI Assistant? @proton.me has just launched Lumo! Powered by open-source large language models (LLMs). And Lumo itself is open source! The future of Generative AI should be open-source and private!

Today, on stage with my improv theatre group in Denmark. 🎹
Tomorrow? I should probably study my lines for Hamlet. Opening night is approaching. 🎭

My first #JNation was a blast! If I had to summarize it in one sentence: pure rock ‘n’ roll 🎸 Huge thanks to the organizers for a fantastic event and to all the amazing people I was lucky to share this experience with! Still can’t believe I met the Nanowar of Steel 🤘🏻 @jnationconf.bsky.social
