I'm very moved that someone who lives as far away as Tokyo has read Apologies Forthcoming. Thank you, Sushidog!
By the way - this is not a big deal - I've never been a tech writer, though several reviewers have assumed that. My previous career was in algorithm development. It seems the misunderstanding was stemmed from a line in my bio, "I gave up tech for writing," which could easily be read as "I gave up tech writing." For clarification I've just changed that line to "I gave up algorithms for writing."
