Today we welcome Matt Klein into our Maintainer Spotlight. Matt is the creator of Envoy, born inside of Lyft. It’s an edge and service proxy designed for cloud-native applications. Envoy was unexpectedly popular, and completely changed the way Lyft considers what and how to open source. While Matt has had several opportunities to turn Envoy into a commercial open source company, he didn’t. In today’s conversation with Matt we learn why he choose a completely different path for the project.

Maxime Vaillancourt joined us to talk about Shopify’s massive storefront rewrite from a Ruby on Rails monolith to a completely new implementation written in Ruby. It’s a fairly well known opinion that rewrites are “the single worst strategic mistake that any software company can make” and generally something “you should never do.” But Maxime and the team at Shopify have proved successful in their efforts in this massive storefront rewrite and today’s conversation covers all the details.

We’re helping Atlassian to promote Season 2 of Teamistry. If this is the first time you’re hearing about this podcast, Teamistry is an original podcast from Atlassian that tells the stories of teams who work together in new and unexpected ways, to achieve remarkable things. Today, we’re sharing a full-length episode from Season 1 which tells the story of the team that fashioned the Apollo 11 spacesuits. When Neil Armstrong stepped on the moon for the first time, we don’t actually see his face. We see his moonsuit. That moonsuit — in effect — is Neil Armstrong; an inseparable part of this historic moment. While the spacesuit kept him alive to tell that story in his own words, what went unnoticed is the extraordinary team that stitched it together.

Join today!Featuring:Gabriela Cowperthwaite – TwitterAdam Stacoviak – Mastodon, Twitter, GitHub, LinkedIn, WebsiteShow Notes:Teamistry is the chemistry of unsung teams that achieve the impossible Season two begins September 21st. New episodes every other Monday. Teamistry is hosted by award-winning documentary and feature film director Gabriela Cowperthwaite. Search for Teamistry anywhere you listen to podcasts or click here to subscribe and listen. In the final episode of Season 1 of Teamistry, host Gabriela Cowperthwaite shines a light on the team of seamstresses and engineers whose meticulous craftwork, creativity, and dedication helped us realize the dream of putting a man on the moon. In this episode, Joanne Thompson and Jean Wilson — two of last surviving seamstresses who worked on the Apollo 11 moonsuits — talk about the intricate seams, needlework, and personal sacrifices that went into outfitting Neil Armstrong. We hear from Homer Reihm, one of the engineers who worked with the seamstresses, and Bill Ayrey, former historian at ILC Dover and Nicholas de Monchaux, author of ‘Spacesuit: Fashioning Apollo’, who take us through the pivotal moments of this monumental task. Also, Janet Ferl, the current design engineering manager at ILC Dover, tells us how the legacy of dedication and teamwork on the Apollo 11 moonsuit continues to inspire the company today.

Gitter is exiting GitLab and entering the Matrix…ok, we couldn’t help ourselves with that one. Today we’re joined by Sid Sibrandij (CEO of GitLab) and Matthew Hodgson (technical co-founder of Matrix) to discuss the acquisition of Gitter. A little backstory to tee things up…back in 2017 GitLab announced the acquisition of Gitter to help push their idea of chatops within GitLab. As it turns out, the GitLab team saw a different path for Gitter as a core part of Matrix rather than a non-core project at GitLab.

This conversation with Hisham covers the gamut of being an open source software maintainer.
