http://cve.mitre.org/ Common Vulnerabilities and Exposures. Public security vulnerability database, sorry, dictionary. The first one of its kind, I think?
http://nvd.nist.gov/ The National Vulnerability Database. A CVE with government backing.
http://www.secunia.com/ Secunia. Another site that offers a vulnerability database and mailing lists.
http://ha.ckers.org/ A regularly updated place with mostly web application specific security commentary (they have a pretty decent JavaScript XSS reference too).
http://www.myspace.com/tritonusprog The ultimate prog-rock experience. Do you enjoy bands like Dream Theater, Angra, Pain of Salvation and Evergrey? Listen to these guys.
http://www.myspace.com/taarn These guys are totally kick-ass. Get your metal fix here while you wait for their first album release!
http://www.loveshack.no/ Crazy Norwegian band constantly on the road performing a great mix of the hits you remember in your 80's youth. A must-see experience, and they take private bookings too!
