TODD SHANDELMAN fondly remembers coding assembly language programs on punch cards for IBM System/370 mainframes. After occupying various other ecological niches in software technology over the years (C, C++, and Perl, to name but a few), Todd's best days are now spent coding pure Python 2.x and 3.x from the Linux command line. In his spare time he is a professional translator of Russian and Hebrew, specializes in foreign-language typography, and can find his way in the dark around Unicode and UTF-8. Todd earned a Bachelor of Science degree in Business Administration from the University of the State of New York. He lives in Houston, Texas, with his wife and son.
