So, you think your data is safe?
http://www.cnn.com/2010/OPINION/01/23/schneier.google.hacking/index.html?hpt=T2

Heat it up
Hit it hard
Repent as necessary.

Priorities:

It's the smith who makes the tools, not the tools which make the smith.

.I never wanted to see anybody die, but there are a few obituary
notices I have read with pleasure. -Clarence Darrow
