Misc:
http://www.osknowledge.org/~marc/software/ Various tools and stuff I have written (currently offline due to some company sending me 'bad mails' and suggest to sue me. The credit card validation stuff is to be found with help from Google, however. ;) )
Mandriva RPMS:
http://rpm.osknowledge.org/ Various RPMS/SRPMS for the Mandriva operating system (formerly known as 'Mandrake Linux'). Probably having more recent versions in the Mandriva tree. Thus, these RPMS/SRPMS are horribly outdated!

Debian .deb packages:
I no longer maintain my .deb packages as I don't use Debian anymore :)
