Retired programmer (much of it in interactive graphics).
Currently publishing eBooks with titles of my favorite author of historical fiction, Joseph Alexander Altsheler. Tools for doing this are written in the Perl programming language running in Linux.
Still trying to prove my conjecture from 1959: Any valuation from the reals onto the non-negative reals is a power of the ordinary absolute value function, where the exponent lies in the interval (0,1].
