Changelog Interviews episodes

July 02, 2021The foundations of Continuous Delivery
This week we’re sharing one of the most popular episodes from our new podcast Ship It. Ship It launched in May and now has 8 episodes in the feed to enjoy…it’s hosted by Gerhard Lazu, our SRE here at Changelog.
In this episode, Gerhard talks with Dave Farley, co-author of Continuous Delivery and the inventor of the Deployment Pipeline. Today, most of us ship code the way we do because 25 years ago, Dave cared enough to drive the change that we now call CI/CD. He is one of the great software engineers: opinionated, perseverant & focused since the heydays of the internet. Dave continues inspiring and teaching us all via his newly launched YouTube channel, courses, and recent books. The apprentice finally meets the master 🙇‍♂️🙇‍♀️

June 21, 2021xbar puts anything in your macOS menu bar
On this episode we’re talking with our good friend Mat Ryer whom you may know from the Go Time podcast. Mat created an awesome open source tool for putting just about anything in your Mac’s toolbar. It was originally written in Objective-C, but it just got a big rewrite in Go and abig rename from BitBar to xbar.
If you don’t use a Mac don’t hit skip on this episode quite yet! There are lessons to be learned for anyone interested in hacking on tools to make your life better. Plus, with this rewrite Mat has positioned xbar to go cross-platform, which we talk about as well.
