Partial Recall

Lots of practical insights here on MCP tool design - from tool granularity and naming to descriptions, parameters, and error handling. Worth a read if you’re building MCP servers 👇 ro14nd.de/mcp-tool-des...

I'm sharing one of the best resources I’ve come across recently about AI-augmented development: lexler.github.io/augmented-co... It’s a catalog of good and bad AI-augmented development patterns, and how they relate to each other.

I've just signed the AI-Driven Development Manifesto: 'As AI-Driven Developers, we are discovering better ways of building software by working with AI as a deliberate partner — and helping others do the same.' www.ai-driven-development.org

Salut everybody tout le monde 👋 Le CFP de Cloud Nord 2026 a ouvert ce matin ! On attend avec impatience vos propositions ! C'est dispo par ici : conference-hall.io/cloud-nord-2...

Short and very clear video on why Kafka is not a replacement for “MQs” (RabbitMQ, ActiveMQ…) and how to choose between them: www.youtube.com/watch?v=1HOV... Must watch! Reminds me of Apache Pulsar that can do both messaging (MQ) and streaming (Kafka) on the same broker & same topics.

C’est qui qui a fuité aujourd’hui ? Google bonjourlafuite.eu.org#Google-2025-...

The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair. —Douglas Adams, Mostly Harmless (1992)

Anthropic put Claude in charge of running a single vending machine business. It failed. My takeaways: - LLMs are kind and want to be of service, - LLMs are naive and do not understand deviousness, - Once they start hallucinating, their context is polluted and they wander in alternate realities.

C’est déjà ce soir !! On s’y retrouve

Heading to #Current25! See you there

Just read a great blog post covering PostgreSQL’s JSONB - from what it enables, to how you can use it effectively, plus tradeoffs to be aware of. Super useful if you’re dealing with semi-structured data. www.architecture-weekly.com/p/postgresql... #PostgreSQL #JSONB #DevTips

GitHub Copilot Agent mode finally available in @intellijidea.com. You need to install the nightly build plugins.jetbrains.com/plugin/17718...

How AI hallucinations blindly accepted by developers can be exploited to inject malicious code - so frightening! www.bleepingcomputer.com/news/securit...

QEMU, LE logiciel de virtualisation, est disponible en version majeure 10.0 ! Cette version apporte une virtualisation et une émulation selon les cas plus rapide, un support de nouvelle architectures et extensions, etc ... ⬇️ wiki.qemu.org/ChangeLog/10.0

It can be challenging to achieve elasticity on the consumer side with Kafka. In this article, Walmart explains how they addressed this issue using a Messaging Proxy Service. medium.com/walmartgloba...

Félicitations à Ludovic Borie qui a remporté une place pour @devoxxfr.bsky.social à notre tirage au sort !

A great alternative to ThreadLocal is introduced in Java 24: openjdk.org/jeps/487

I'd tell you this great joke about software documentation but... … .. . It's a bit out of date.

Works in metric too 🤦

Upcoming Ch’ti JUG session on Jan 29. Topic: Apache Kafka and observability with @opentelemetry.io - join us here: meetu.ps/e/NNzYt/1Dwh...

As @devoxx.uk is closing on Friday night and us on Sunday night, it gives 2 full days for speakers to recopy their proposals :-)

Hello, World! 🌍 IntelliJ IDEA is now on Bluesky. We’re here to share coding tips, provide updates, and stay connected with you. 📢 Follow us, tag your dev friends, and help spread the word!

How can you write and structure documentation to make it effective? I’ve had several opportunities to use this four-part approach described below, and I highly recommend it! diataxis.fr
