Crossplane is now a CNCF Graduated project 🎉 Great news!

I’m looking forward to joining the Kenya Java User Group for a session on building LLM-powered applications with Java and Spring AI 🍃

In this session, I discuss Modular RAG architectures and how to implement them using Spring AI, covering also observability and developer experience aspects. It felt rewarding to share the work I've contributed to Spring AI to support these patterns. @springio.net www.youtube.com/watch?v=yQQE...

If we're having a debate, and at any point you say, "let's ask ChatGPT", then you lose by default.

Introducing Dev Services for #SpringBoot using #Arconia by @thomasvitale.com

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-...

More than 50% of the articles published on the web is now AI slop... graphite.io/five-percent...

I created Arconia to enhance the development of modern enterprise applications with #Java. You can add it to an existing Spring Boot application to boost developer experience, reduce boilerplate, and seamlessly adopt cloud native patterns. Fully open source. www.thomasvitale.com/arconia-dev-...

Enhance the Spring Boot developer experience with Arconia Dev Services: zero-code and zero-config infrastructure provisioning. Add one dependency. That's it! Databases, event queues, observability platforms, AI services and more. All powered by Testcontainers! www.thomasvitale.com/arconia-dev-...

KubeCon Europe is accepting talk proposals now! And the CFP closes Oct 12! That's TOMORROW! You don’t need to be a pro speaker. You just need a story, a lesson, or an experiment worth sharing. ☆彡 My CNCF blog post on teaming up with GenAI when writing proposals: www.cncf.io/blog/2025/08...

With Dapr Workflows you can define and orchestrate activities, supporting durable execution, fault-tolerance, and observability. When you combine them with Spring AI, you can build AI agents at scale that even span across multiple apps. Interesting blog post by @salaboy.com dzone.com/articles/dur...

I'm glad to see Knative's Graduation as a CNCF project 🎉 No Kubernetes cluster is complete without Knative Serving! www.cncf.io/announcement...

🚀 Excited to share that Spring AI now has its own community-driven GitHub org! A dedicated hub where the community can incubate projects, contribute integrations, and shape the future of AI using #SpringAI. Explore & get involved 👉 spring.io/blog/2025/10...

Jackson 3.0.0 (GA) release now starting! github.com/FasterXML/ja... #java #json #xml #csv #cbor #csv

I love performing with my improv comedy group 🎹 🎭

I had lots of fun preparing this presentation with @marcushellberg.dev at @springio.net. Spring AI and Vaadin are a powerful combo for implementing real-world patterns for LLM-enhanced Java applications. www.youtube.com/watch?v=cLWF...

#JUnit 6.0.0 is released! ✨ Java 17 and Kotlin 2.2 baseline 🌄 JSpecify nullability annotations 🛫 Integrated JFR support 🚟 Kotlin suspend function support 🛑 Support for cancelling test execution ⏭️ New `--fail-fast` mode for ConsoleLauncher 🧹 Removal of deprecated APIs docs.junit.org/6.0.0/releas...

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

Java 25 is finally here 🤩

Happy to see GraalVM 25 is out 🎉

🤩🤩🤩

When it comes to testing Spring applications, my go‑to person is Philip Riecks. On top of the great resources produced over the years on the subject, he created the Spring Test Profiler, an OSS project to improve your tests’ quality and speed. Totally recommended! pragmatech.digital/products/spr...

Apertus is Switzerland’s first large-scale, multilingual language. “Apertus” means “open” in Latin. And Apertus is really open! Open data, open weight, open source ☀️ You can run it locally, choosing between the 8b or 70b variants, or via the PublicAI app. www.swiss-ai.org/apertus

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...

Supplychain attack has hit the npm ecosystem. AikidoSecurity reports that 18 widely-used packages, including chalk, debug, ansi-styles, have been affected. These packages are downloaded over 2 billion times per week, making this potentially the largest npm breach. www.aikido.dev/blog/npm-deb...

Devcontainers support seems to be broken on macOS with the latest versions of Podman Desktop and Podman. Did any of you experienced the same? I haven't found any solution yet and had to downgrade for now. @podman-desktop.io github.com/podman-deskt...

At @springio.net, Saeed Zarinfam describes the challenges of managing development environments and shares useful patterns and best practices for solving them using DevContainers, including great tips to handle scenarios with monorepos and distributed systems. m.youtube.com/watch?v=FOWg...

I wish Java had a more straightforward way to manage CA certificates. It would be so convenient being able to use the OS trust store automatically. Or loading PEM certificates directly via a single environment variable like SSL_CERT_FILE or SSL_CERT_DIR.

I really liked this presentation about authorization with Spring Security by @garnier.wf at @springio.net. Fantastic followup to last year's session on authentication and protection against common security attacks. #springio www.youtube.com/watch?v=-x8-...

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.

Crossplane 2.0 was one of the main things in the cloud native space I was really looking forward to this year 🚀 Game-changer features: applications as first-class citizens, namespaced resources, and native support for composing Kubernetes resources. @crossplane.io blog.crossplane.io/announcing-c...

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 had a really great time at Spring I/O ☀️ This is the recording of my presentation about Modular RAG Architectures, where I cover several RAG patterns that you can implement in your Spring Boot application using Spring AI + Arconia (for enhanced developer experience). #Java #AI #SpringBoot

Europe’s digital house is built on foreign foundations. Our latest study reveals that over 74% of publicly listed European companies host email—and by extension their entire tech stack—on US platforms subject to foreign laws. Find out why and what needs to change 👇

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?

If you are looking for Java, Spring Shell, GraalVM based CLI tools, I would recommend to take a look at the following: 1. ttcli github.com/wimdeblauwe/... 2. arconia-cli github.com/arconia-io/a...

Boiling here at home in Cyprus but I put the finishing touches a couple of days ago on this preprint: What Does 'Human-Centred AI' Mean? doi.org/10.48550/arX... Wherein I analyse HCAI & demonstrate through 3 triplets my new tripartite definition of AI (Table 1) that properly centres the human. 1/n

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

This is brilliant! Thanks, @sonjadrimmer.bsky.social!

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...

A long overdue blog post about our new endeavour with @thomasvitale.com Developer Experience on Kubernetes www.salaboy.com/2025/07/26/d... #kubernetes #book #devexp #CloudNative

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!

This was fun!

I had an interesting chat with @kevindubois.com and Olimpiu Pop on the latest episode of the @infoq.com Podcast. We talked about developer experience, cloud native, serverless, generative AI, and the role of #Java as a modern ecosystem to tackle all these areas. www.infoq.com/podcasts/jav...

The irony is that dev teams who work in ways that appear to get the best results from LLMs - small steps, prompting with tests, rapid feedback loops, continuous testing, code review and integration, and good separation of concerns - have little need for the tools.

Feature branching is a lie we tell ourselves. It feels safer and more controlled, but in reality, it’s slowing you down, increasing risk, and making your integration problems someone else’s future nightmare.

I’m glad I’ve been re-confirmed as an Oracle ACE Pro ☺️

Production-ready features are no longer enough for software frameworks and tools. If you don’t invest in improving the developer experience, prepare to see your market share taken by competing projects that prioritize developer experience!

Use Signal. We promise, no AI clutter, and no surveillance ads, whatever the rest of the industry does. <3
