writes with this excerpt from the New York Times' "Bits" column: "Tens of thousands of programmers, writers, accountants and other workers labor at home doing contract work for companies like Google, Hewlett-Packard and NBC. The computers they use contain software that takes snapshots of what they are doing six times an hour. The snooping occurs randomly, making it impossible for the computer user to game the system. It is probably more invasive than what happens to those working in offices, where scooting through Facebook entries, shopping on Cyber Monday, and peeping at N.S.F.W. ('Not Safe for Work') Web sites on corporate computers is both normal and rarely observed by managers."
