Opensource, sysadmin and IT security expertise.
As a strong believer in sharing knowledge/ software and having benefited from Open Source for years, this site publishes techie notes and tools either developed or referenced in my work. The site is mostly aimed at Sysadmins & IT-Security people.
Note: Most documents on this site has not been updated since 2005 and as publication focus shifted to public issue queues or company internal systems). However, some of the security content for example, may still be relevant.
