Managing ML Performance in the Database: A friendly guide to LOW / MEDIUM / HIGH on OML

Leave a Comment / Articles, Oracle Machine Learning (OML) /

A common question when using Oracle Machine Learning (OML) on Autonomous Database / Autonomous AI Database is: “What exactly do LOW, MEDIUM, and HIGH mean. And when should I use each one?” These are not informal labels. They are predefined database services (service names in your wallet / tnsnames.ora) that map to resource consumer groups. […]

I let two AIs review my PRs: One breaks my fastAPI code, the other fixes It

Leave a Comment / Articles, Generative AI, Projects & Demos /

Pull Requests are where good engineering habits either level up… or quietly get replaced by “LGTM, ship it.” You open a PR. You do the responsible things: Then your reviewer asks: What happens if the uploaded filename contains weird Unicode? And you realize the truth we all share: PR reviews are human-scaled. Attackers are not.

When Housing Becomes a Luxury Tax: Why Young Spaniards Are Giving Up on Their Future

Leave a Comment / Articles /

I am writing this in English and publishing it on Medium and LinkedIn because what is happening in Spain with housing should not stay a local, private frustration. It is a systemic problem in a European country that likes to present itself as modern, attractive and “open to talent”, while quietly making decent housing almost

From Lat/Lon to Hexagons and Neighbourhoods: Learning H3 with Madrid

Leave a Comment / Articles, General Data Science /

How a bird-sighting anomaly project turned into a reusable H3 geospatial demo. When you work with geospatial data, you quickly run into this question: I have latitude and longitude… now what? This article is a practical walk-through of a Jupyter notebook that answers exactly that, using H3 and Madrid as a playground. The notebook originally

JSON vs TOON: Is your data format really the problem?

Leave a Comment / Articles, Generative AI /

Lately my feed is full of posts claiming that TOON cuts LLM token usage by 30–60% and that JSON is basically “legacy bloat”. As someone who spends her days helping customers bring AI into production at Oracle, I was curious… but also a bit skeptical. So instead of arguing in the comments, I opened a

This marks the start of a new chapter: OCI leading AI infrastructure, industry apps rebuilt with AI agents, and Safra’s legacy of growth. But here’s the big question: ➡️ Can a dual-CEO model accelerate innovation?➡️ Should tech companies prioritize bold visionaries at the top or disciplined operators who ensure flawless execution? Oracle’s future looks bright.
