Bill Harlan kept us on our toes by criticizing the amount of time we spent on system administration. Zhang Zhifang attempted to compile vplot on his Linux-PC. Martin Karrenbach and Matthias Schwab completed the first port of the entire SEP environment to Linux. Stew Levin removed the remaining bugs. Jon Claerbout, Bob Clapp and Sean Crawley shared the authors' enthusiasm and helped by kindly attending to our bug reports. James Rickett manages the arrival of the new Linux-PCs and is gearing up as SEP's future Linux system administrator. Biondo Biondi and Mihai Popovici regularly challenged our follies by asking the right questions. Thanks to you all.
