Sven Haardiek


I am a Software and Product Developer at the Greenbone Networks GmbH in Osnabrück, Germany. My main focus is to develop the operating system based on Debian for our products and the open source core utility OpenVAS.

Apart from this I am interested in several other open source software projects, space travel, mathematics, boxing and network policy.

Also I like penguins.

Not all articles in this blog are from myself, since I like also publish for other people who have to say something interesting
