Here is one: How much time is needed to crack a password by
             brute-force?

At the bottom of their "time table": 

length: 10, complexity: a-zA-Z0-9 + symbols ==> 91800 years

Which simply means you need to increase the length of your passwords to
compensate (that, and the services storing them need to use a proper
work adjustable password storage function like bcrypt or scrypt).

For whatever speed the gpu crackers achieve, there is a password length
that exceeds their capabilities.  Which is why arbitrary length limits
on so many password protected services are actually more dangerous than
good.  You are prevented from keeping pace with the gpu crackers.
