Technical Properties of Arbitron's PPM™ System

A number of radio veterans are questioning the accuracy of Arbitron's Portable People Meter™ system because listenership reports are frequently quite different from those of the old diary system. 25-Seven Systems Director of Engineering Barry Blesser addresses those questions in this white paper (HTML, PDF).

SeisMac

One of Dan Griscom's outside projects has been developing a seismology application called SeisMac, which changes your Apple MacBook or MacBook Pro into a three-axis seismograph. You can read the column he wrote about the developent process in a Seismology Research Letters' Electronic Seismologist column.
