We talk about their upcoming 20th Anniversary Edition of The Pragmatic Programmer, what prompted a 20th Anniversary Edition, what has changed and what has stayed the same in the 20 years since, where they see things going based off what they have seen, and much, much more.Our Guests, Andy Hunt and Dave Thomas@PragmaticAndy on Twitterhttps://toolshed.com/Andy’s Now Page@pragdave on Twitterhttps://pragdave.me/Conference AnnouncementsLambda Days 2020 just announced their CFP!
