Changelog Interviews

We sit down with Tobias Koppers of webpack fame to talk about his life as a full-time maintainer of one of the most highly used (4 million+ dependent repos!) and influential tools in all of the web. Things we ask Tobias include: how he got here, how he pays himself, has he ever gotten a raise, what his typical day is like, how he decides _what_ to work on, if he pays attention to the competition, and if he's ever suffered from burnout.

We partnered with Red Hat to promote Season 4 of Command Line Heroes — a podcast about the people who transform technology from the command line up. Season 4 is all about hardware that changed the game. We’re featuring episode 3 from season 4 — called "Personal Computers: The Altair 8800 and the Dawn of a Revolution."

Matthew Hodgson (technical co-founder) joined us to talk about Matrix - an open source project and open standard for secure, decentralized, real-time communication. It's open source, it's decentralized, it's end-to-end-encrypted, and it's also self-sovereign. Matrix also provides a bridge feature to bridge existing platforms and communication silos into a global open matrix of communication. A recent big win for Matrix was Mozilla's announcement of switching off its IRC network that it had been using for 22 years and now uses Matrix instead.

Frank Karlitschek joined us to talk about Nextcloud - a self-hosted free & open source community-driven productivity platform that's safe home for all your data. We talk about how Nextcloud was forked from ownCloud, successful ways to run community-driven open source projects, open core vs open source, aligned incentives, and the challenges Nextcloud is facing to increase adoption and grow.

Stephanie Morillo (content strategist and previously editor-in-chief of DigitalOcean and GitHub's company blogs) wrote a book titled The Developer's Guide to Content Creation — it's a book for developers who want to consistently and confidently generate new ideas and publish high-quality technical content.

On this episode, we talk through this sponsorware experiment in-depth. We learn how he dreamt it up, how it went (spoiler: very well), and how he had to change his mindset on 2 things in order to make sustainability possible.

Yetunde Dada from QuantumBlack joins Jerod for a deep dive on Kedro, a workflow tool that helps structure reproducible, scaleable, deployable, robust, and versioned data pipelines.

Finally, Jerod asks Yetunde about her passion project: a virtual reality film which debuted at the Sundance Film Festival in January.

Jon Thornton (Engineering Manager at Squarespace) joined the show to talk about tech debt by way of his post to the Squarespace engineering blog titled "3 Kinds of Good Tech Debt".
