I've been involved in the world of computers and networks since 1992. I first got involved with SETI@Home back in 1996 and had it running on various different machines for the next 5 years. Only recently I reconnected with the project.
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
