about this notebook
Hi, I'm Mika.
I build small Linux things and write down what I learn while making them. This site is both my open learning journal and my personal writing home.
The field notes are the messy middle: bugs I traced, concepts that clicked, systems I misunderstood, and mental models I want to keep. Writing is where some of those threads become longer essays and articles.
The goal is not to pretend I know everything. It's to leave a useful trail of what I tried, what broke, what worked, and what I learned next.
