How can I disable Mac OS Lion asking if I really want to open a downloaded file?

Question

I already tried this:

cd ~/Downloads
find . -print0 | xargs -0 xattr -d com.apple.quarantine

But it doesn't seem to work under Mac OS X 10.7 (aka. Lion) anymore:

xattr: ./cabin/Cabin-Bold.otf: No such xattr: com.apple.quarantine

display all extended attributes via xattr and see whether some new attribute is set on the file — Yahia, Commented Jul 28, 2011 at 20:59
Unix type commands to configure one's Operating System... not really a programming question. — Sparky, Commented Jul 28, 2011 at 21:01

I haven't tested this under Lion but

defaults write com.apple.LaunchServices LSQuarantine -bool NO

and then restarting should totally disable this functionality.
