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 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.

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

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.

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.

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.

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.

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.
