Part 10: Agents came alive in LangChain4J + Ollama 💡 Part 11 (Sat 20:00 CET): Can we give the entire system memory that persists in PostgreSQL? One landscape, many agents, real continuity. Join the experiment 👉 youtube.com/live/Jpid86_... #Java #AIAgents

🚀 Just dropped Part 9 of my Java AI adventure game series. This one had everything: persistence fixes, broken models, Google SDK experiments, and… a plot twist I didn’t see coming. 👉 Video: youtube.com/live/xppcyTU...

Thanks for uploading! The session was such a fun experience!

Sorry, i have to postpone my Livestream today for health reasons...maybe i'll be able in the coming days again. youtube.com/live/xppcyTU...

Tried to implement LLM memory persistence in my little AI text adventure with #LangChain4j during a live coding session. Spoiler: persistence was the real final boss. 🕹️ Finally cracked it (off-stream) and made a repo for everybody: 👉https://github.com/JohannesRabauer/langchain4j-spring-jpa-memory

👾CyberJAR Live: Java, JavaFX, and Experiments with Raspberry Pi This Thursday, I'm joined by @frankdelporte.be, Java Champion and JavaFX+RPi guru, to explore the world of #Java on the embedded. For those who wanted to tinker with RPi but didn't know where to start :) youtube.com/live/axbx2kT...

🌳 Java devs: ever feel like AI in Java is a wild forest? Guess what—tools are finally landing: meet the Java AI toolbox with @spring-ai.bsky.social & @langchain4j.dev Ready to wield? Let’s go! #JavaAI #SpringBoot #LangChain4j

🚀 Just built custom Ollama models in Java (Qwen3 + LLaMA 3.2:1.7B) — and things got chaotic 😅 Live coding, broken prompts, wrongful victories, and some real lessons for #JavaDev + #AI. 🧵 Here’s what went down (and I need your help for what’s next) 👇

Part 7 of our AI game development series is live — more about exploring ideas together than ticking off a checklist. #AI #GameDev #LLM #JavaDev

🧠 Thinking LLMs are cool… until they start thinking too much. Just wrapped up another live coding session in #LangChain4J testing thinking-enabled models. Here’s what happened 👇 #Java #LLM #AItools #GenerativeAI

Are you also often uninspired when you need to think of useful test data for your unit tests? Is ‘John Doe’ your best test friend? Do not worry, Datafaker comes to the resc#javajava

The latest live coding session was... something else. AI logic, function calls, broken ASCII art. 🎥 Catch the next session here: youtube.com/live/jbnWaC0... #LiveCoding #Java #AI #OpenSource

Just finished a live coding session playing with AI coding assistants and trying to swap @spring-ai.bsky.social with @langchain4j.dev in a Java project. Here's what I learned 🧵👇

👾Unboxing all #Java 25 JEPs! Watch me unbox🎁 the goodies that the upcoming JDK LTS release brings us - from faster startup to improved profiling: www.youtube.com/watch?v=On0B...

🧙♂️⚔️ The AI adventure continues... and this time, we’re rolling for persistence! Join me live as I tinker with: 🧠 LangChain4J (bye Spring AI?) 🎨 Stable Diffusion for story visuals 🗃️ PostgreSQL to finally store our epic quest 👉 youtube.com/live/6KEObwx... 🧵👇

You know some #Java haters? They probably think like in this video ▶️ youtu.be/m4-HM_sCvtQ?...

In Session 4 of my live-coded Java AI story game, I finally delivered on the promise: ✨ AI-generated ASCII art! ...and it was 🔥 awful. 🎥 Watch the replay here: 👉 www.youtube.com/live/lGACZWU...

🧵 Live Coding Session #4 – Saturday 20:00! I’ve been promising AI-generated ASCII art in my game for a while now. It’s finally happening on saturday. …but there's a catch.

That is quite funny! I'm basically doing the same thing with Spring AI and Vaadin as a Live-Coding-Series! www.youtube.com/playlist?lis...

👾 New on CyberJAR: Distroless Images, Hope or Hype? Are #distroless really that small and secure as advertised? Not always😲 I compared distroless to alternative solutions and tested them with Go and #Java. Results...? Watch the video and find out! www.youtube.com/watch?v=_yOp...

🚨 Just unlocked Spring AI → Ollama function calling in session 3 of my LLM game dev series. All built in Java, live-coded. Let me break it down 🧵

We should actually check if it's a quarkus project and then simply speed up the playback to 2.0x or something 😅
