Around the time PARC was forming in Palo Alto, I was working as an editor at an evening newspaper in Mississippi.
By 2 p.m., when we were smudged with ink from elbow to fingertip, the reporters and typesetters would go home and the managing editor and I would settle in to wait until the press run was complete.
Our real job was to just sit and listen carefully for a change in the hum of the presses - to listen to them in the same way and for the same reasons you listen to a new baby sleeping in the next room.
It forever changed and eased the way many of us do our work.
