Definition of DevOps
Step 1: On one team, put the people with the knowledge and control necessary to change the software, see the results, change it, see the results. Step 2: Use automation to take extrinsic cognitive load off this team, so that it needs fewer people. That’s it, that’s DevOps. Step 1 describes the cultural change that …
Development aesthetic: experiments
Software development is a neverending string of “What happens if I…?” Each new runtime, language, or tool is a new world with its own laws of nature. We get to explore each one with experiments. Objective Today I added another alias to my PowerShell $profile: To use that alias in my current shell, I need …
Don’t just keep trying; report your limits
The other day we had problems with a service dying. It ran out of memory, crashing and failing to respond to all open requests. That service was running analyses of repositories, digging through their files to report on the condition of the code. It ran out of memory trying to analyze a particular large repository …

(this is a transcription of the talk by the same name. Here is a video.) Collaboration is crucial in software teams – and not only among people. We need our software, our tools, and our automations to collaborate as well. But what does that mean? I have four prerequisites for you here, and then four precautions …

How do we get a development team to function closer to our preferences, and still let people operate as self-actualized humans? In Dynamics in Action, Alicia Juarrero describes complex systems such as people in terms …
Collective problem solving in music, art, science, and software
Or: the Origins of Opera and the Future of Programming. (video, or TL;DR, or abstract) At the end of this post is an audacious idea about the present and future of software development. In the middle are points about mental models: how important and how difficult they are. But first, a story of the origins …

Does caring scale?
Does caring scale? We can’t all care about everything. We have cities without clean water, a criminal justice system full of injustice, and oceans clogged with paper bags. There are too many important causes to catalogue, much less champion. We can only contribute to a few. We can’t all care about everything. At my house, …
Folding Tradeoff Space

Deployments caused problems, so we did fewer …
