Doesn't even mention what they probably lost in theft during the blackout...can you imagine?
Imagine a Walmart, and the power goes out.... You can bet they have backup generators that come back real quick! (of course, their POS system is a

Nothing wrong with unix and its great for these sort of things as quite a lot of terminal stuff can be treated as a dumb terminal meaning that theres
less chance of people hacking the system
