Massive thanks to @stephanjanssen.be and team for organising another great edition of @devoxx.com!

@snicoll.be, thank you for the talk on Devoxx Belgium 2025 on SpringBoot 4. May I ask you to review my guide how to write SB starters. Is it still actual and provide the best practices for SB 4 kpavlov.me/blog/spring-...

#Mokksy 0.5.0-Alpha1 is ready for testing github.com/mokksy/ai-mo... New features include an #Ollama mock server, initial support for #A2A protocol v0.3.0, colored HTTP request logs, and updated Kotlin compiler options with kotlin-stdlib 2.0.10.

📢 Kotlin community! Don’t miss this livestream on the new version of IntelliJ IDEA. We’ll share updates that improve the Spring experience, demonstrate interactive coding with Kotlin Notebook, and highlight many other new features. Set a reminder 👇

Google has introduced a new Transformer model called Mixture-of-Recursions, which lets each token go through a different number of processing steps based on how much “thinking” it needs, helping the model use less memory and computation while improving performance. youtu.be/MfswBXmSPZU

Poland will start its first-ever pilot of a shortened working week this July as the government seeks to meet social needs.

Their system prompts need more refinement and supervision and human approvals while making the decisions, but the business model is seemingly interesting and promising.

Anthropic put an AI chatbot in charge of a shop. The results show why AI won’t be taking your job just yet.

I wrote a new #blog post about why #testing #prompts in isolation isn’t enough 🚨 Your app usually generates prompts on the fly. Static tests miss how it behaves in real-world use. You should test the service itself—dynamic prompt logic, context, full flows kpavlov.me/blog/llm-eva... #ai #testing

First day at #DevTalksRomania. Today I am hosting a workshop on building AI agent on #Kotlin, #LangChain4j, and #Quarkus

There are only 103 unique #LEGO sets like this, and only 2 happy owners in #Estonia: @antonarhipov.bsky.social and myself 😎 #KotlinConf25 #Kodee

The DevUI is especially useful to play with the ADK

#Mokksy AI Mocks 0.4.0 now supports Google #Gemini #VertexAI mocking. Enable deterministic testing with local API simulation - no production dependencies needed. Useful for stable CI/CD with #AI components. Docs: mokksy.dev/docs/ai-mock... #AITesting #DevInfrastructure #Gemini​​​​​​​​​​​​​​​​

I found a nice #AI #wiki generator. It helps to understand project structure and architecture, e.g. deepwiki.com/mokksy/ai-mo... Free for open-source projects. They are asking to add a badge to README file, and the wiki will be updated weekly deepwiki.com

Another #KotlinConf around the corner 😍 Not a single edition was disappointing, in fact I went home energised and full of ideas and excitement to build more things in #Kotlin. This year will be special for me, since after 4 editions I'll be joining as an employee 😱 Find me at the booth 🥰

I've implemented #Kotlin #coroutines support for #langchain4j-kotlin. This allows for writing cleaner code with #suspend-functions instead of dealing with CompletableFuture. Still experimental, but you may try it here: github.com/kpavlov/lang...

🔥🔥🔥 A big milestone! Congrats, all users and contributors 👏🏻🎉
