### Re: Amusing answers to tests

If you have a problem with the rules, tell us about it, and we can talk, but a lot of people find these rules intuitively satisfying/correct, so you'll have to do a lot of convincing to get another collection of rules accepted. I don't know if I accept the law of the excluded middle for infinite se...

### Re: Have you ever used the values for e or pi as a password?

When I need a 4 digit pin I find that 1729 is such a wonderful number to use (smallest number expressible as the sum of 2 positive cubes 2 different ways). Okay, now that's just borderline asking for it. EVERY self-respecting geek likes 1729. It's my favorite 4-digit number. I never use it. 9271, h...

Not for long!

It reads "pie" which equals pi * e. Since for completeness' sake you also have to check pi, that makes a lot more combinations to check. It's secure.

You could try ArrayLists and Iterators. They can provide the same functionality as arrays and for loops but without the need to specify numbers of items.

Just think of what a logarithm represents. So: log4 9x^2 = log2 5x-8 9x^2 = 4^(log2 5x-8) because Log is the inverse of an exponential. Notice that the only remaining base is 2, and 4 is a power of 2. So since 4 = 2^2, we have 9x^2 = (2^2)^(log2 5x-8) and by rules for exponents, you know it's the sa...
