“It’s not the upfront capital that kills you, it’s the operations and maintenance on the backend.” Just read this in the book The Phoenix Project by @realgenekim.bsky.social , Kevin Behr, and George Spafford. Funny how actual it sounds.

Next Monday @iamsoham.bsky.social and I will be delivering two insightful talks at the Utrecht Java User Group. Join us to learn how AI agents can power autonomous DevSecOps pipelines and how memory works in both humans and AI Agents. www.meetup.com/nl-nl/utrech...

Always a pleasure to be back at @springio.net . Especially when talking about building agentic systems with Spring AI! #java @spring-ai.bsky.social

I’m seeing a lot of posts claiming n8n is dead. I’ve never used it and I wonder if it’s a tool that has value when building enterprise scalable agents? Or did it serve a small niche that was agglutinated by something else?

"Products are only overnight successes in reverse. The iPod was not, the iPhone was not, the Watch was not." - Tim Cook (youtu.be/74qPQt_5DdM)

Building agentic system is not about machine learning, just like building enterprise systems is not about low-level programming. @albertheijn.bsky.social has understood that. They're hiring seasoned backend engineers to implement agentic systems: www.linkedin.com/jobs/view/44...

Started playing Eternal Darkness with a friend yesterday. A game released in 2002. We get stuck. I tell him to check ChatGPT. He checks YouTube instead. He’s not a technical person, he’s an airline pilot. What do you infer from that?

1/ Amidst so much change and uncertainty in the world, there's something grounding about waking up to a photograph like this. My dad watched men land on the moon in 1969, when he was only 8 years old. He's the reason I care about space exploration.

This is my favorite climate change chart. Japanese monks, aristocrats, and emperors kept meticulous records of cherry blossom festivals for 1,200 years and accidentally built the world's longest climate dataset.

Prepping slides & demos for my Voxxed Days Amsterdam 2026 deep dive tomorrow Packing in Memory, Advisors, RAG, Tool Calling & MCP, Agentic Patterns, A2A & ACP, LLM-as-a-Judge, Guardrails… and somehow fitting it all into 2 hours! See you there 👉 amsterdam.voxxeddays.com/talk/?id=12905

Yesterday, @bsbodden.bsky.social and I delivered our Designing Multi Agent Systems with Spring AI hands-on lab at JavaOne in San Francisco. More than 35 people showed up and it was the lab with most registrations of the day. 🙏🙌☕️ #java

I made the classic founder mistake this week: I built the vision instead of the product. Follow the thread /1

It's difficult for me to believe that the cost of coding has got nearly to zero. Especially as someone who's been coding with agents consistently for almost one year.

Redis 8 just made KEYS and SCAN faster and safer Operations that used to take 12–14 seconds on large datasets can now complete in just a few milliseconds — making previously discouraged commands viable for in production. Read the full article at: redis.io/blog/faster-...

If the third era is about autonomous execution, then the real question might be: are our evaluation systems, testing practices, and engineering standards ready for it? Interesting article by the founder of Cursor: x.com/mntruell/sta...

Can’t wait to be back at @springio.net !! The conference that made me love conferences!

@anthropic.com says Claude helped NASA plan a 400m drive for Perseverance on Mars. For AI engineers, the lesson is: it was not a bigger model. It was context. Clear constraints. Domain knowledge. Structured outputs. Simulation. Human review. Reliability comes from system design.

Anthropic just announced they're giving 6-month free of Claude Code 20X for open source contributors! If you maintain a popular project or contribute across open source, you should apply! claude.com/contact-sale...

When does DinD (Docker in docker) start falling short and when is it just enough?

What is your experience with DinD (Docker in Docker)? Would you recommend it? What use case did you try to build with it?

Docker-in-docker powered by SpringBoot. How cool is that?! A complete hands on lab with no IDE required, no environment setup, no git pull, and no friction. Just open it and start building. #javabubble

Love that KLM now let us use their planes’ wifi with no limitations for free! Now I can vibe code at 30,000 ft - currently working on my social media tracker agent built with Spring AI and Redis

For future reference: When using Gemini models, we're required to explicitly enable structure outputs in the ChatClient. I was also using Spring AI Vertex AI integration instead of Google GenAI. Thanks @tzolov.bsky.social and @ddobrin.bsky.social!

This was something I discovered while trying to build a reliable multi agent with Spring AI fully within GCP. With OpenAI it works flawlessly. With Gemini, constant structured output issues... Has anyone else seen this? #java #javabubble

Am I the only finding Gemini to be less consistent to adhere to structured output than OpenAI?

#SpringAI Tool Search Tool - Build smarter AI apps that discover tools when they need them 📖 Blog: spring.io/blog/2025/12... 🔗 GitHub: github.com/spring-ai-community/spring-ai-tool-search-tool ✅ On-demand tool discovery ✅ Multiple LLMs ✅ 34-64% token savings @spring-ai.bsky.social

In 2 weeks we’re kicking off the Belgium @kotlinlang.org User Group with @sch3lp.bsky.social! The first session since 2019 😍 We’re starting off with a talk, and afterwards we’ll have an open space. There’ll will be lots of Kotlin and Kodee goodies 😁 See you there! www.meetup.com/belgian-kotl...

What happens when you get Kotlin, Spring AI, Redis, and data from the Apollo 11 together? A whole new way of exploring one the most important milestones humanity has ever accomplished! Kotlin conferences just hit different! And it was a pleasure to be part of Kotlin Dev Day! @kotlinlang.org

JSON is the go-to format for LLM tool responses, but alternatives like TOON, XML, CSV, YAML can potentially improve token efficiency and performance. Find how to configure #SpringAI tool responses formats and optimize for your use case: spring.io/blog/2025/11... @spring-ai.bsky.social

I don't even know anymore if LLMs are dropping the quality of anything produced by humans in every field (not only software development) or if everything has always been as mediocre as it is today. We're shipping faster and in more quantity, sure, but clearly at the expense of quality.

This week is all about Kotlin as I get ready to speak at Kotlin Dev Day! Can't wait for a day full of Kotlin talks led by a few of the best engineers I have had the pleasure of meeting. If you still haven't got a ticket, get one with 20% discount with the code: kotlinfriends@kdd25 #java #kotlin

All my fellow @kotlinlang.org server devs, there is still time to fill the annual Ktor survey! If you're using Ktor then please consider filling the survey, and help us continue making it better.

I went to the @mlopscommunity.bsky.social conference as an attendee today, but when I learned anyone could get on stage and deliver a lightning talk, I didn’t hesitate! 7 minutes to let the audience know how semantic caching can optimize agentic ai costs!

Semantic routing improves predictability and efficiency in AI systems. RedisVL classifies user queries without LLM calls, reducing token usage and latency. Combined with LangGraph, it creates a deterministic flow for routing, execution, and decision logic. Read how here: medium.com/@bhavana0405...

Two more weeks to submit your talks for @kotlinconf.com! In case you’ve been procrastinating like me.. This weekend might be the perfect time to write yours too! Come and share any awesome work you’ve done with @kotlinlang.org! Good luck 👍 sessionize.com/kotlinconf-2...

Next week I'll be delivering two sessions! One virtually with Camille Nigon from Red Hat and the second one at the Kotlin MeetUp in Eindhoven! At both I'll talk about how Redis can help your agentic applications save on time and cost using vector search. Don't forget to RSVP! #java #kotlin

I'm delighted to announce that the CFP is open for Arc of AI 2026 @arcofai Link: www.arcofai.com/cfp Submission deadline: Dec 20, 2025 Speaker Notification: Jan 10, 2026 Conference dates: Apr 13-16, 2026 Looking forward to your submissions and/or participation at the conf.

I went on vacation in September and stopped using social media during the period I was off. I’m returning now and I’d like to share a few memories from our trip to Korea and Japan.

I'm overwhelmed with so many emotions right now, mostly joy. I'm proud of how far I've pushed myself. If you had told that kid struggling to learn programming 24 years ago that this is how life would turn out, he never would have believed you.

🚀 Spring AI 1.1.0 GA Released 🔧 Better MCP Integration ... 🔐MCP OAuth2 server protection 🔄 Recursive Advisors ...📦 Developer Experience: ... Over 850+ commits Kudos to the entire Spring AI community! 🙌 Find more: spring.io/blog/2025/11... @spring-ai.bsky.social

The funny thing about building a SaaS is that I always feel like I only need to add one more feature. Sometimes I even think that if I spend a whole month working non-stop on everything I have in mind, I'll be satisfied. I'm naive.

Building a SaaS is much more than building the expected functionality itself. It also means putting together everything around it, including auth, RBAC, billing, admin pages, user experience, and all the details that make it feel complete and reliable.

🤖⚖️ LLM-as-a-Judge with #SpringAI Evaluating LLM output is challenging. Traditional metrics fall short, and human evaluation doesn't scale. LLM-as-a-Judge uses LLMs to evaluate AI-generated content, matching human judgment 📖 spring.io/blog/2025/11... 🛠️ github.com/spring-proje...

LLMs may get expensive fast. At the same time, vector DBs (eg Redis) are versatile but underutilized I delivered a talk at JFall yesterday about three strategies that can be implemented with vector DBs to reduce LLM calls. But the truth is that there are many more! #java github.com/redis-develo...

Using slidev (sli.dev) for the first time. Looking forward to delivering my first presentation with it tomorrow at J-Fall Conf in the NL - @rafaelponte.bsky.social told me about it in the beginning of the year, but took me a while to experiment with it.

Can artificial intelligence do basic math? I was listening to Anthropic's recent video "How AI Models Think" based on their research on interpretability and found a few insights very interesting. One for example is that there's evidence that LLMs can do simple math (addition).

1/ "NOPERM User user:209 has no permissions to run the 'flushall' command" That's the message I got when running "FLUSHALL" on my production Redis instance. 😮‍💨 My team and I developed an internal platform for us to track our work. The chosen database? Redis, of course. #redis @redis.io

One of the things people are afraid of since the term artificial intelligence has been coined 70 years ago by John McCarthy is that it may rebel against us.
