## Java compound interest calculator

I wrote a thing to calculate compound interest and print out how much you’ve accrued after each period. It’s pretty basic but I was bored and didn’t want to do it via calculator. The code is in InterestCalculator.java, sample output is below:

```Initial principal: 5000.00
Interest rate:     0.05 (4.93%)
# of ann. periods: 4

## Moved the old Aimster page.

The old page that was at http://www.evanhoffman.com/aimster/ was moved to http://www.evanhoffman.com/aimster.20100920/. Basically so everything goes through WordPress.

Also faking the date of this post to 1/1/2008 so it doesn’t show up as a “new” post, but does show up with the “Aimster” tag.
