What could be more American than pie and puns based on the world’s only sane date-writing system? Put them together and you get today—Pi (π) day—which is to say, 3.14 (March 14). Most of the world doesn’t get our month-day format, just as most of the world doesn’t feature pies in their cuisine (at least, not proper pies). Which is fine, because that leaves more pie for us.

In honor of the occasion, Take Control Books is offering 31.4% off (one day only!—3/14/2019) all ebooks, on a wide range of tech topics. Use coupon code PIDAY2019. Enjoy!
