System Notes: Expeditions
A record of technical explorations across computer systems and software internals.
catme0w | Recording Systems, Culture, and Human Traces
Notes by catme0w. There are computer systems, forgotten internet history, games, culture, and everyday life.
catme0w documents what lies beneath the surface:
From OS kernel internals to the forgotten history of the internet;
From GPU instruction pipelines to the human traces left behind in social networks.
Alongside these are more ordinary records.
Notes from games played, fragments written while traveling, and fleeting thoughts not meant to be lost.
The subjects here may seem unrelated.
Yet they all come from the same person, reflecting how understanding takes shape across different moments and different things.
