In the early 90's, Sven introduced me and many others at the math and cs campus of the FU Berlin to vim, mutt, screen and zsh. He also was such a passionate activist for freedom with and through (simple) software. Thank you for your dedication and passion for simplicity, Sven, I still choose, use and build such tools, also because of my early experiences through your mentorship back then.
A part of me thinks he just entered Ctrl^a-d.
RIP, Sven
