Its not All Hallows Eve that day, but it is All Hallows Eve Eve on Monday, October 30th. Did you know that Oct 31 = Dec 25? Most programmers and computer scientists and many mathematicians get those two dates confused. Why? In decimal, base ten, 25 = 2 x 10 + 5 x 1, i.e. 2 tens and 5 ones. In octal, or base eight, 31 = 3 x 8 + 1 x 1, i.e. 3 eights and 1 one. So Octal 31 is equal to Decimal 25, Oct 31 = Dec 25. 2 tens plus 5 ones is equal to 3 eights and 1 one. October 31 = December 25, so Happy Halloween and Merry Christmas. There are only 10 kinds of people in the world. Those who understand binary, and those who don't! 10 in base 2 binary = 2 in base ten decimal. 100 in binary is 4 in decimal. 1000 in binary is only 8 in decimal. Mark
