02. How do I determine if I have a valid credit card number?
Credit cards use the Luhn Check Digit Algorithm. The main purpose of this algorithm is to catch data entry errors, but it does double duty here as a weak security tool.
For a card with an even number of digits, double every odd numbered digit and subtract 9 if the product is greater than 9. Add up all the even digits as well as the doubled-odd digits, and the result must be a multiple of 10 or it's not a valid card. If the card has an odd number of digits, perform the same addition doubling the even numbered digits instead.

04. What are the ethics of hacking?
The FAQ answer is excerpted from: Hackers: Heroes of the Computer Revolution by Steven Levy
Access to computers -- and anything which might teach you something about the way the world works -- should be unlimited and total. Always yield to the Hands-On imperative.
All information should be free.
Mistrust Authority. Promote Decentralization.
Hackers should be judged by their hacking, not bogus criteria such as degrees, age, race, or position.
You can create art and beauty on a computer.
Computers can change your life for the better.
