Someone told me my posts “sound like AI.” So I built an AI detector in Java with Quarkus + LangChain4j. It turns out detection is harder — and more fascinating — than you’d think. Read the full breakdown ↓ buff.ly/Qm1KYIB #Java #AI #Quarkus #LangChain4j

I so fun working on cagent, Docker's agent builder (github.com/docker/cagent) It's so rewarding to be able to quickly try ideas, without writing code. While keeping a lot of flexibility and power.

One of the tools that really made a difference for me as a software engineer in the past few years is @openrewrite.github.io. Kudos to the team and special thanks to @timtebeek.github.io for introducing me to it and providing guidance for using it and working with it effectively 🙏🏻 /1

medium.com/@sayantann7/... Building apps that work to demo solutions can be done in many ways and usually quickly. Once you move into the phase of longer running and scalable approaches you have to spend more time getting it right. There are many approaches and tools you can use to help. (1️⃣/3️⃣) 🧵

🎉 Spring Framework 7 brings retry capabilities INTO core! No more external spring-retry dependency needed! Reach for the RetryTemplate When you need MORE control than Retryable can give you 💪

🚀 Spring Boot 4 tip: Jackson 3 brings JsonMapper as the preferred way to read JSON! Notice the new import. No more ObjectMapper from com.fasterxml! JsonMapper is now your go-to for JSON operations in modern Spring apps.

I'm back! @doctolib.bsky.social

Curious about the upcoming 4.0 release of @maven.apache.org? Join Hervé, Guillaume, Frank and myself @foojay.io to learn more!

Nanit a économisé 500 000$ par an en remplaçant AWS S3 par une solution internalisée pour son stockage objet. (P) Une belle étude de cas pour repenser les architectures cloud à grande échelle. 👉

On the CRaC side I would also add that there's a significant security risk of using this technology: it takes a snapshot, which means that the snapshot _may_ contain things like credentials. I don't think most devs realize that.

Supporting this in build tools is not trivial. There is actually something _similar_, but not quite, in the GraalVM native plugins for PGO, but the "how to run an app in such a way you get meaningful profiling data" is an unsolved problem.

Good explanations from @0.5ritter.de about the diffs between Leyden and GraalVM. I think an important thing to surface is that Leyden requires steps which are not easily integrated in a build pipeline: you need to build an app, then profile it, then build the AOT cache, then repackage.

Bonjour @aeris.eu.org Est ce que tu aurais des resources à me recommander pour m’opposer à l’installation de vidéo surveillance dans les parties communes d’une résidence?

Immutable releases announced at GitHub Universe! Once tagged, releases can’t be changed. No more worrying about malicious actors swapping out assets or moving tags. Single-use version tags with signed attestations. This is the supply chain protection open source really needs 🔒 #GitHubUniverse

Introducing JUnit 6.0.0: a transformative update that unifies versions, elevates minimum requirements to Java 17, and introduces streamlined support for Kotlin suspend tests. Enjoy enhanced testing performance with the new CancellationToken API, built-in JFR listeners and many more—migrate today!

J'ai pris une explosion de mon temps de démarrage avec Spring-boot avec l'extension Jsonb de postgresql. Je partage donc ce que j'ai appris dans l'histoire : eventuallycoding.com/2025/10/kotl...

Note: this is a “reboot” produced by Atari which is amusing since the first console war was Atari vs Intellivision

The reason for creating tests is not to achieve 80% code coverage, but to gain the assurance that the application will still work after a change.

lol job wants me to participate in a pilot program for tracking important developer metrics like… number of PRs. they swear up and down this won't be taken out of context for performance decisions 😬

We are launching Quarkus public community calls! The first one will be on November 4th and we will talk about how to better support developing large applications with Quarkus. github.com/quarkusio/qu... .

Today was my last day at Elastic. Over the last 9 years I saw it grow from 400 to 4000 people, have its IPO and build a great product lineup. A great company, even if rather different than the one I joined. I wasn't actively looking, but a small startup reached out to me. 1/2

Depuis 2 semaines j'utilise le bot Claude (de la github app éponyme) C'est trop bien Se reposer sur un third party pour critiquer le code, ça n'implique aucune guerre d'ego Ultra utile pour expliquer 1 PR en restant haut niveau à coup de diag mermaid (en tant que reviewer, ou pour mes reviewers)

My comprehensive guide on building #AI #agents in #Java with the #ADK framework! 🤖☕ I've bundled everything you need to get started: my full article, the video recording at @devoxx.com, a codelab, the slides, an updated template project, and code samples, all in one place.

Teaching @openrewrite.github.io, my favorite moment is watching devs write their first custom recipes, realize they can query any codebase like a database, then immediately plan to refactor their entire monolith. Today's lab: From "what's a visitor pattern?" to "I can transform 1M lines" with tests

One day the industry will recognize the drawbacks of AI agents and nondeterministic automation, and rediscover the UNIX philosophy of chaining together small purpose built tools in a low cost and predictable way, otherwise known as shell scripts.

"The greatest benefit of an API mock is that it lets consumers perform integration tests even before you implement the API. Being able to test how the API would behave as early as possible is what enables the alignment with consumers." apichangelog.substack.com/p/why-api-mo...
