Not to toot my own horn, but I managed to impress my 16-yr-old son the other day. We were watching Jon Stewart or Stephen Colbert and they did something about robots taking over the world. In any case, part of the titles went by in binary and I was able to translate the binary into ASCII letters and into English. For example: 0100000101010000010100000100110001000101
broke down to: 01000001 01010000 01010000 01001100 01000101
or: 65 80 80 76 69
or: APPLE
And it was a story about Apple computers. He was impressed with my supreme geekery. Good thing too, as I'll be the only one in the household who'll be able to communicate with our metallic overlords...
