As we "Silver Surfers" (older folks on the Internet) know, sometimes we have trouble with our computers. I had a problem yesterday, so I called Richard, the eleven year old next door, whose bedroom looks like Mission Control and asked him to come over. Richard clicked a couple of buttons and solved the problem. As he was walking away, I called after him, 'So, what was wrong? 'He replied, 'It was an ID ten T error.' I didn't want to appear stupid, but nonetheless inquired, 'An ID ten T error? What's that? In case I need to fix it again.' Richard grinned.... 'Haven't you ever heard of an ID ten T error before? ''No,' I replied. 'Write it down,' he said, 'and I think you'll figure it out.' So I wrote down: ID10T I used to like Richard, that little wise guy !
