About me

Hi, my name is Sebastian. I'm a Vim and Git addicted software developer from Germany :)

I made software for technical, administrative and safety management of yachts over the last decade. Now I work in parking space management.

On this site you find mostly information about projects I created in my spare time and that I want to share. Sometimes I also turn on my webcam to watch birds or my cat.

Who is Dixie Flatline?

One of my favorite characters from Neuromancer.

A famous computer hacker named McCoy Pauley, who earned his nickname by surviving three "flat-lines" while trying to crack an AI. [...] Before his death, Sense/Net saved the contents of his mind onto a ROM.
