Code compares performance of row-by-row copying to column-by-column. Used in a blog post
class ArrayExample{
static int size = 10240;
static int A[][] = new int[size][size];
static int B[][] = new int[size][size];
static void copyij(){
for( int i = 0; i < size; i++){
for( int j = 0; j < size; j++){

sp0rus / PasswordStrength.java
Created April 20, 2011 00:45
Program asks user for password, assumes password is random and all symbols were produced independently. The program then calculates the entropy of the password based on number of possible characters and length of the password.
import java.util.*;
public class PasswordStrength {
final static double POSSIBLECHARS = 62; //Upper and Lower Alphebet (52), Arabic Numberals (10)
public static void main( String[] args ){
double entropy = 0;
int pwlength = 0;
String password;
