Jeff Duntemann


 I am a writer, editor, technologist and contrarian living in Scottsdale, Arizona. Although I've worked as a programmer, I've been in the technical publishing industry (both magazines and books) from 1985 until I retired in 2015. I co-founded Coriolis Group Books in 1989 and ran editorial until the company closed in 2002. Most of my book-length work has been on computer technology. (See ASSEMBLY LANGUAGE STEP BY STEP and LEARN COMPUTER ARCHITECTURE WITH RASPBERRY PI, as well as many more titles now out of print but available used.)

 In my loose moments I'm an amateur radio operator (callsign K7JPD), amateur astronomer, and SF writer. My first SF novel, THE CUNNING BLOOD, appeared in 2005 but I have been selling SF stories to magazines and anthologies for 45 years, and was on the final Hugo Awards ballot in 1981.I now have seven volumes of SF and fantasy on KDP Select.

 My wife Carol and I met in high school and have been married for 45 years. We live in Scottsdale with two Bichon Frise dogs.

 There's more about me on my Web sites: (my blog) (tech projects) and, which is a quick index to all that I've published online.
