Time complexity of Euclid's Algorithm

...rations is linear in the number of input digits. For numbers that fit into cpu registers, it's reasonable to model the iterations as taking constant time and pretend that the total running time of the gcd is linear. Of course, if you're dealing with big integers, you must account for the fact that ...

Is “double hashing” a password less secure than just hashing it once?

...on the server if you had a large user base, because you are relying on the CPU load to slow down the number of requests. It means that if you add more CPU power, you are reducing the restriction on those brute force attackers. -- However, you are completely correct about the scalability, and the wid...

How can I shuffle the lines of a text file on the Unix command line or in a shell script?

... Here is a first try that's easy on the coder but hard on the CPU which prepends a random number to each line, sorts them and then strips the random number from each line. In effect, the lines are sorted randomly: cat myfile | awk 'BEGIN{srand();}{print rand()"\t"$0}' | sort -k1 -n | c...
