I am Matthias Melcher. Born 1953; since 1972 at the University of Heidelberg; since 1981 in the Computer Center (as “Wissenschaftlicher Angestellter”). Initially in network infrastructure. Since the early gopher days, I have drifted more and more towards content.
My blog name “x28″ means nothing, it is just my userid since nearly 25 years.
