My name is Sascha and I'm interested in various facettes of nerdiness. Mostly in programming the web. I'm also interested in science, mostly biology, philosophy, physics, new technologies, gaming, social networking, music, software... most of the geeky stuff. These are my random ramblings about things that interest me.
