A call for kindness in open source (Interview)
Adam and Jerod talk to Brett Cannon, core contributor to Python and a fantastic representative of the Python community. They talked through various details surrounding a talk and blog post he wrote titled “Setting expectations for open source participation” and covered questions like: What is the the purpose of open source? How do you sustain open source? And what’s the goal?
They even talked through typical scenarios in open source and how kindness and recognizing that there’s a human on the other end of every action can really go a long way.

#Hacktoberfest isn’t just about a free shirt (Interview)
#Hacktoberfest is a once per year event in the month of October celebrating open source. For many it’s an on ramp to open source, PRs galore for maintainers, and t-shirts for those who submit 5 or more pull requests. In the end, however, it’s about the awareness of open source and its significance to the greater good to humanity as we know it.
Adam and Jerod talk with Daniel Zaltsman, Dev Rel Manager at DigitalOcean and key leader of Hacktoberfest to cover the backstory, where this project began, its impact on open source, how it has had to scale each year by many orders of magnitude, and of course we cover how you can play your part in #Hacktoberfest and give back to open source.

Join the federation?! Mastodon awaits... (Interview)
We talked with Eugen Rochko, the creator of Mastodon, about where Mastodon came from the problem it aimed to solve. How it’s not exactly Twitter alternative, although that’s its known claim to fame. Why it’s probably not going anywhere. The ins-and-outs of federation, getting started, running an instance, why you would want to — cool stuff you’ve never considered could be built on top of Mastodon. And finally, the story behind naming posted content a “toot”.

The first cloud native programming language (Interview)
Jerod talked with Paul Fremantle, the CTO and Co-Founder of WSO2, about their new programming language, Ballerina — a cloud-native language which aims to make it easier to write microservices that integrate APIs. They talked about the creation of the language and how it was inspired by so many technologies, cloud native features like built-in container support, serverless-friendly, observability, and how it works with, or without, a service mesh — just to name a few.
