I am happy to announce that GoUtils is now part of the Masterminds project on GitHub.

GoUtils implements many of the string utility functions found in Java's Apache Commons. Alex, the lead developer on GoUtils, created the library in 2014. Other Masterminds libraries, notably Sprig have long relied...

Kubernetes provides a home for all your containerized applications. But how do you get that home furnished with the likes of databases and web apps? That's where Helm comes in. If Kubernetes is your home, Helm is where you get your furniture.

Sometimes it's nice to work with GitHub from the command line. This post covers three tools for working with GitHub: hub, ghi, and github-release.

Most of the time, when we work with GitHub, we use the main git client. This is great for working with source code, but what about interacting with other...

There are lots of tools for searching files on the UNIX (macOS, Linux) command line. Which one do you use? Let's look at grep, find, and ag to understand which tool is the best for a particular search job.

A while back, the official Deis blog posted The Story of Helm to celebrate Helm's birthday.

Back then, I wrote:

Troubled by my long blogging hiatus? This article explains why: My Ruby broke. But this time, I solved that problem once and for all.

For a non-rubyist, the hardest part about Ruby (particularly on a Mac) is getting it installed correctly. After a frustrating Middleman breakage, I decided to take...

Earlier this week I had the opportunity to participate on a CoreOS-hosted "Ask Me Anything" panel. The topic of the panel was the release of Kubernetes 1.4, and the state of the surrounding ecosystem.

I'm a huge fan of Tim Hockin, who has done a ton of the (often thankless) behind-the-scenes work...

Go in Practice is now available in print and ebook. After a long haul for Matt Farina and I, the book is complete. Pausing for a moment, I realize how, behind all the code samples and callout boxes, some small part of life is captured in those pages.

Matt and I each went through some pretty crazy...
