From their explanations I learned something. Use mostly symbols and uppercase letters in your passwords, make them long, by putting for example 14 dashes into your password.
Most people use lowercase only, and some digits. Attacking programs have the best chance when they systematically first try to attack lowercase and digits.
If you use non qwerty layouts (I use the Neo-Layout) you might be able to type unicode chars, such as λαμβδα (lambda) or √Ω³ and can put that into your password too.
