PaiPix Linux is a compilation of Free Software, based on Knoppix, that is meant to be used in any environment but with special emphasis on science and technologies. It should provide an open door to the public including not only the tools used by the scientists but also the best free applications that make your computer more interesting for any usage. If you like it for office, video or even gaming, who knows if someday you can get curious and give a look at the scientific applications that are in your DVD. PaiPix can be used at home, in medium and even large size organizations where the sharing of the compressed DVD image and the included afs file system support make it extremely powerful.
