# Welcome to Notes on Systems Design: From Sand to AI This is a collection of notes and articles (some people call it a "digital garden[^1]") about different aspects of the design of [[What Are Digital Systems?|digital systems]]. Note that this page is a combination of content I have authored with curated content pulled from different books and online sources. All credit is given to the best of my knowledge. Let me know otherwise.

Contrary to a blog, where articles and essays have a publication date and start decaying as soon as they are published, a digital garden keeps evolving: owners keep on adding, editing, and refining their notes. Some people also call it the "second brain".
