I work at genua, a German IT security company, focusing on AI security. Over the years I've contributed to projects like Scapy, written about hash visualization, and found security vulnerabilities.
But I've also learned that understanding the mind matters as much as understanding systems. That's why I write about sleep, attention, and letting go.
