He started his career as a PDP-11 assembly language programmer in downtown Tokyo, learning what "patience" in real life means by punching a 110 baud ASR-33 Teletype frantically. He used to be able to put in the absolute loader sequence through the switch panel without consulting the DEC programming card.

Since then, his computer language experiences include 8051 assembly, FOCAL, BASIC, FORTRAN-IV, Turbo/MS C, VB. VB.NET, and C#.

Now, he lives with his wife, two grown-up kids (get out of my place!), and two cats in Westerville, Ohio.
