When your image is in the trash, will giving away cash and cars remove the stench? SCO Group, best known as the company that sued Linux users and vendors, hopes so. "SCO has gone through some rocky times," president Darl McBride admits. SCO is trying to win back Unix developers by paying them $1,000 to take training in its EdgeBuilder development software at its upcoming user conference. The participant who builds the best wireless app with EdgeBuilder can win a 10-cylinder BMW or $100,000 in cash. That still may not be enough to forget the lawsuits.
