Q. "A password with 8 characters, consisting of Upper case/Lower Case &0-9"
A. 221,919,451,578,090 combinations.

Provided the characters were a random sequence, (not a word in a dictionary), 8 is safe for on-line login : it would take centuries to try all the possible combinations online.
8 characters not safe for offline use though, where more guesses-per-second are possible : crackable within a day.

Failure: It turns out that, more often than, a team with a higher SD wins. In my language, that...

Thread 'Roulette wheel physics and probability'

Hi all, I've been a roulette player for more than 10 years (although I took time off here and there) and it's only now that I'm trying to understand the physics of the game. Basically my strategy in roulette is to divide the wheel roughly into two halves (let's call them A and B). My theory is that in roulette there will invariably be variance. In other words, if A comes up 5 times in a row, B will be due to come up soon. However I have been proven wrong many times, and I have seen some...
