The author claims no credentials or special qualifications,  other than a compulsion to write.  This book is somewhat of a departure from his other major work, HOW-2 Meet Women: The Shy Man's Guide to Relationships. He has also written the Software-Building HOWTO. Lately, he has been trying his (heavy) hand at short fiction.
A Linux user since 1995 (Slackware 2.2, kernel 1.2.1), the author has emitted a few software truffles, including the cruft one-time pad encryption utility, the mcalc mortgage calculator, the judge Scrabble® adjudicator, and the yawl word gaming list package. He got his start in programming using FORTRAN IV on a CDC 3800, but is not the least bit nostalgic for those days.
Living in a secluded desert community with wife and orange tabby, he cherishes human frailty, especially his own. 
In fact, he is a school dropout and has no formal credentials or qualifications whatsoever.
Those who can, do. Those who can't . .. get an MCSE.
Sometimes it seems as if he has spent his entire life flouting conventional wisdom and defying the Voice of Authority saying, "Hey, you can't do that!"
