	Malicious hackers have a lot more time on their hands than
good guys.

	They do not, however, tend to publish bugs.  So, what you see
in public is that the many good guys who look at systems with source
available announce problems, while the bad guys, who look at both
source and binaries, do not announce problems.  This is what
statisticians refer to as the self-selection problem.

	Drawing inferences from bad data will probably lead you to bad
inferences.

Pet peeve of the day: Security companies whose protocols dare not
speak their name, because they don't have one. Guilty company of the
day is now V-One.
