*Description:*
The roots of modern digital computing go back nearly two hundred years, 
and through a series of pass-around artifacts from the past century, we 
will explore how the pioneers of the field and their groundbreaking 
decisions and technologies have led us -- for better or worse -- to 
today's Internet-enabled world.

*About Sebastian:*
Mr. Lindley has been in the computer industry since he sold his first 
program (a printer driver for Heathkit HDOS) in 1980. He has used system 
from the earliest 8-bit microprocessors, through the PDP-11 and VAX, up 
to IBM mainframes, and has managed to write programs that did not crash 
on most of them. Mr. Lindley has been a GNU/Linux user since 1992 and 
has been free of proprietary software since 2001. Most recently he has 
been pleased to be an adjunct professor at Mesa Community College.
