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.

We talked with Stephanie about why developers should be writing and sharing their ideas, crafting a mission statement for your blog and thoughts on personal brand, her 4 step recipe for generating content ideas, as well as promotional and syndication strategies to consider for your developer blog.

Caleb Porzio is the creator & maintainer of Livewire, AlpineJS, and more. His latest open source endeavor was announced as “sponsorware”, which means it lived in a private repo (only available to Caleb’s GitHub Sponsors) until he hit a set sponsorship threshold, at which point it was open sourced.

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. They discuss what Kedro’s all about and how it’s “changing the landscape of data pipelines in Python”, the ins/outs of open sourcing Kedro, and how they found early success by sweating the details. 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”. We talked through the concept of “good tech debt,” how to leverage it, how to manage it, who’s in charge of it, how it’s similar to ways we leverage financial debt, and how Squarespace uses tech debt to drive product development.

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 1 from season 4 — called “Minicomputers: The soul of an old machine.” This is the story of Minicomputers and how they paved the way for the personal computers that could fit in a bag and, eventually, the phones in our pockets.
