Thanks to everyone who attended my talk with @shelajev.bsky.social at @javazone.bsky.social yesterday! We hope you now feel confident making sure your #AI #Java apps are always getting better!

The slides from our session are available at speakerdeck.com/edeandrea/ja...

Farewell dinner after @javazone.bsky.social

Nice surprise from ‪@javazone.bsky.social‬ today! Looks like I'll be joining @shelajev.bsky.social‬ on stage!

Yay! I knew an account here would be useful! Thanks for sharing!

Non-deterministic? No problem! You can test it! by Eric Deandrea & Oleg Šelajev Testing is hard, which is why developers tend to avoid it. Testing non-deterministic things is even harder, which is unfortunate, since we're all writing AI-...

🧪 "But how do you test AI apps?"

Watch Java Champions @shelajev.bsky.social & @ericdeandrea.dev show how to test non-deterministic AI applications using Testcontainers, LangChain4j, Quarkus & Ollama.

Practical solutions, no excuses!

How to Run Gemma 3 Locally with Docker Model Runner | Docker Explore how to run Gemma 3 models locally using Docker Model Runner, alongside a Comment Processing System as a practical case study.

Running Gemma 3 locally with no API costs? Yes.
Free to experiment? Absolutely.

We built a full-on comment processing system using Docker Model Runner + #google Gemma 3 — no cloud, no third parties. Just local power.

🎉 Meet Docker Model Runner:

✅ Run AI models with the tools you’re using today
✅ GPU acceleration on Apple Silicon
✅Pull models as OCI Artifacts
✅ No extra setup, just dev

Local-first GenAI just got fun.

🎉 It's not often one gets to post ✨amazing✨ updates about boring, day-to-day tech these days.

But hear me out, this is pretty revolutionary:

github.com/testcontaine... is a thing! 🔥🔥🔥

Now you can have the magical testcontainers experience in your favourite PHP applications.

If you weren't at @Jfokus.se last week here's your chance to watch my talk with @shelajev.bsky.social about #testing non-deterministic things!

It was so much fun presenting this! I feel so privileged to share @jfokus.se with you!

Full room for @ericdeandrea.dev and @shelajev.bsky.social's session about testing non-deterministic systems at #Jfokus . Seems like many developers are curious how to actually test the results of LLMs 🥲.

@jfokus.se #AI

Thank you for having me! It was great to talk about the testcontainers modules ecosystem and what cool things you can do when building one!

All Hands-on lab are fully booked this morning!
#Quantum with Gavin King, Java for Cloud with @rustam.no, Testcontainers with @shelajev.bsky.social and LangChain4j with @kevindubois.com, @danieloh30.bsky.social, @geoand86.bsky.social and @ericdeandrea.dev

Attending @jfokus.se and looking for a good session? Join @shelajev.bsky.social and myself tomorrow Feb 4 at 11:00 in Room C1 to learn how to #test #ai and #nondeterministic systems!

Due to a happy coincidence, I managed to get into the #DingGukesh Fide chess world championship match!

It feels pretty surreal to see a part of chess history in the making!

Super excited to be presenting at @jfokus.se this year! @shelajev.bsky.social and I will be talking about how to test non-deterministic things!

Oleg Šelajev Oleg is a developer advocate at Docker. Ask me about AI, Developer productivity, and Testcontainers. https://testcontainers.com/ Sometimes a video is the best way to explain things about technology, ...

If you found me here, consider as well Youtube 😅 I make short videos with folks I meet at conferences and they are fun and minimally educational: www.youtube.com/@shelajev/sh...
