Britain is testing a speed trap using satellites. It calculates the speed of a vehicle between two points. They have confirmed that they can read your license plate from space in all weather 24hrs a day.

Hacking Weak Passwords

Stewart Schatz — Mon, 05 Apr 2010 11:00:00 +0000

There is a post on One Man’s Blog that I thought was pretty interesting. It is about the use of weak passwords and how they can get you into trouble.

The following is a list of common passwords from the post:

Your partner, child, or pet’s name, possibly followed by a 0 or 1 (because they’re always making you use a number, aren’t they?)

The last 4 digits of your social security number.

123 or 1234 or 123456.

“password”

Your city, or college, football team name.

Date of birth – yours, your partner’s or your child’s.

“god”

“letmein”

“money”

“love”

Assuming the hacker has a reasonably fast connection and PC here is an estimate of the amount of time it would take to generate every possible combination of passwords for a given number of characters.
