Overview

About this notebook¶

This is a collection of random notes regarding data science (or adjacent) topics, in no particular order and not exhaustive. I jot them down whenever I work on a topic and have time to document it.

Having these notes has sometimes saved me time in the past. Whether I’ll still need them now that LLMs have emerged and are widely available for quick questions and answers remains to be seen.
