Brute Force

I have a Kensington Combination Lock for my Laptop. I have not used it for two months, and when I wanted to use it yesterday, i couldn’t remember the combination. While I was travelling on the Subway or listening to boring courses on university I tried a Brute Force Attack, since the lock was too expensive to throw it away. At around 7:55am this morning i found the right combination after having tried more than 900 of the 1000 possible combinations.
Brute Force Attacks are boring but effective :).
