Suppose that someone has a random 8 character password (not a dictionary word), all in lower case. There are 26^8 = 208,827,064,576 combinations. If you only check one every 30 seconds, it will take: 104,413,532,288 minutes = 1,740,225,538 hours = 72,509,397 days = 198,519.9 years to check all of them. So I'm feeling quite safe at this point. The moral of course is not to use a dictionary word (or simple derivative like flower28) as your password, since there are *far* fewer words than random combinations of letters, and brute force attacks are much more likely to succeed.
