#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.

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.

I just like building stuff 🥰

Let's gather to talk about #Java Gatherers. If you're in London, please join me at the London Java Community (LJC) meet up on Monday August 18th: www.eventbrite.co.uk/e/ljc-meet-u...

Vibe coding is the WORST IDEA of 2025 according to Dave Farley: www.youtube.com/watch?v=1A6u...

Since Nvidia’s primary objective is to sell more GPUs, they open-source all their research. Recently, they explored how far RL scaling can take LLMs. ProRLv2: Expanding LLM reasoning boundaries through 3,000+ RL steps across five domains, setting a new state-of-the-art among 1.5B reasoning models.

Just because an airplane doesn’t fly the same way a bird flies, does it mean it doesn’t fly?

After three weeks using Claude Code, I can say vibe coding just isn’t for me. My biggest problem is that it moves too fast. Sure, it eventually gets to the result I want, but it’s hard to follow the design choices along the way. That makes it way too easy to end up with messy, hard-to-maintain code

New Redis release, but with a twist. It includes our first Rust patches to Redis Query Engine! In particular, it ships the new TrieMap implementation I wrote with Henk Oordt, as part of @mainmatter.com's ongoing collaboration with Redis.

Using AI to analyze thousands of frames taken by drone, a mountain rescue team has found the body of a doctor who had been missing in the Alps since September 2024.

I see a lot of people generating images to test GPT-5 capabilities, but it’s important to note that GPT-5 does NOT generate images. It’s still the GPT-Image-1 model released in April of this year that is generating the images.

Already better than Discover... Great example of the unreasonable effectiveness of simple algorithms leveraging the human intelligence innate to an app with a follow graph and likes. Conclusive proof you don't need a team of ML engineers and custom models to make a highly engaging algorithm.

I'm in Brazil and had to do the same thing. Android does not have that functionality, so I used this app. play.google.com/store/apps/d... I hope they add it soon. In Brazil they do something awful, bots call you and hang up, just to check if your number is active. Check out my block log!

Eu ri com isso aqui. 😂😂😂

Compartilhando um pouco de conhecimento em vídeo. Recomendo 3 livros que mudaram minha carreira. Aproveita e deixa sua recomendação livros também:

🚀 GPT-5 is out — and that’s AMAZING news for RAG. Every time a new model drops, people declare “RAG is dead” because of bigger context windows. This time they’re also pointing to better accuracy with massive token counts. Let’s talk about why they’re wrong. 🧵

"Do you want a second opinion? We can ask Gemini."

"GPT-5 opens a whole new world of vibe coding."

I’m reading a book called Ichigo Ichie about the Japanese concept with the same name and I wonder why the author thought that Steve Jobs, Bill Gates and Dan Brown making a million dollars are good examples. I expected to read a book about mindfulness and presence, not accumulation and productivity.

It’s been eight years since I moved to Europe. That means I’ve now spent twice as much of my adult life here as I did in Brazil.

Durante a aula discutimos os seguintes tópicos: 1️⃣ Introdução a async e Mensageria 2️⃣ Lidando com perda de msgs 3️⃣ Lidando com msgs duplicadas 4️⃣ Lidando com dual writes 5️⃣ Lidando com concorrência e race conditions 6️⃣ Lidando com msgs fora de ordem 7️⃣ Refletindo sobre o mito do Exactly-Once Delivery

Depoimento massa sobre minha aula de “Processamento assíncrono em sistemas distribuídos com Mensageria” no #DevEficiente 😍 Essa aula foi ministrada no formato síncrono no nosso programa Formação Pessoas Plenas. ⭐️ Em breve ela estará na nossa plataforma de cursos!!

Am I the only one getting classic Mac OS X feelings with OpenAI's website graphic designs? I love it by the way.

That's how I did Bluesky's infra: cloud agnostic using "primitives" like Linux, HAProxy, and of course Redis 🙏 Sadly, it's just not realistic to expect most people to build like this. Requires a special skillset to be able to use these tools directly and people (understandably) want an abstraction.

The #Redis vector sets are really cool. Just using basic movie information (e.g. "Title: <title>, Genre: <genre>, Year: <year>, Synopsis: <synopsis>" results in quite good similarity searches. Also the ability to `SETATTR` and `GETATTR` and filter on them is awesome.
