Personal Library · Knowledge OS

The Library.

Books, videos and ideas that shape how I think — and what they apply to. The library is the memory layer of the OS: every theme connects to a project, a habit, or a decision somewhere on this site.

Six recurring themes: Data engineering · Business & strategy · Running & longevity · Italian language · Learning to learn · Finance & long-term.

Notes & insights — as of 2026-05-06

"The data model you choose will determine which questions are easy to ask and which are impossible."

— Designing Data-Intensive Applications
Directly shapes how I design data pipelines at work. Schema decisions are irreversible at scale.

"Exercise is the single most powerful tool we have to extend the quality, not just the quantity, of our lives."

— Outlive, Peter Attia
Changed how I read /run and /gym data — less about performance, more about longevity signal.

"Non capire tutto è normale. Capire qualcosa ogni giorno è sufficiente."

— personal note · Italian study log
Not understanding everything is normal. Understanding something every day is enough.
