In "An AWKward Modem" (p. 28), I show how to write a tiny modem in 5 lines of AWK and shift it into the near-ultrasonic range. 🔊

Thank you for nominating my Print to Play article :) I also completely agree with you about the LNK talk at Black Alps.

But I have another idea, will try tonight :P

Good question! This was my 1st intent 2 years ago, but it didn't work out eventually, I'm not sure why. I'll try again tonight and will let you know :)

Google AI search result for “was 2010 fifteen years ago?” returning: “No, 2010 was 14 years ago, not 15 years ago. The current year is 2025, and to find the number of years ago 2010 was, you subtract 2010 from 2025, which equals 14. Current Year: 2025 Past Year: 2010 Years Ago: 2025 - 2010 = 14 years”
