Why Naming is the Hardest Programming Problem

March 8, 2018

Adam and I were pairing, working through a critical piece of our program's architecture. The cursor sat blinking. We had been staring at it in awkward silence. We were stumped.

Introducing Helm Emeritus Core Maintainers

January 11, 2018

One reality of the open source world (and, indeed, any passion projects) is that sometimes we have time to participate, and other times we don't.

Why Brigade Doesn't Do YAML

January 4, 2018

Brigade newcomers often ask me why Brigade doesn't use YAML.

April 29, 2017

A CapsLock key is useless. So make it into something better: A Hyper key.

Back in 2014 I wrote about how I remapped my MacBook's CapsLock key to make it act like CTRL-CMD-SHIFT-OPTION, essentially giving me a new modifier key in the tradition of the old Hyper key.

For the last few years I have benefitted...

The Microsoft acquisition of Deis is my second major acquisition in a few years. Not long ago, Revolv was acquired by Google.

Earlier this week, Microsoft and Deis jointly announced the acquisition. Wired ran an interesting story with interviews, while TechCrunch and 20+ others explored Deis' history
