TL;DR: startSpan is easier and measures a duration. Use it if your work won’t create any subspans. startActiveSpan requires that you pass a callback for the work in the span, and then any spans created during that work will be children of this active span. I’m instrumenting a Node.js app with OpenTelemetry, and adding some …
We get better decisions by forming a shared (overlapping) understanding. We do that with participation from everyone who changes the software.
It also works with VSCode devcontainers and on GitPod. Because Step 1 in any new project is a reproducible development environment, and Step 2 is get it in production. Step 3 is implement something. Copy this code: systemsthinking-dev/poker-in-elm at starter (github.com) This is my accomplishment for the day, so I’m here to share it with …
Copying someone else’s team structure is like seeking the phone in the bathroom closet every time.
Today, I found a bug before I noticed it. Like, it was subtle, and so I wasn’t quite sure I saw it–maybe I hadn’t hit refresh yet? Later, I looked at the trace of my function and boom, there was a clear bug. Here’s the function with the bug. It responds to a request to …

As a software engineer, what is your job? and what is your value? On many teams, the work is “add features to this codebase.” We congratulate teams for moving JIRA tickets from “defined” to “delivered.” Meanwhile, the value to the business depends on value to the customers, or to people or software who in turn …
Today I need to do some calculations for an article, so I want to persist them. The best way to do this is in a notebook, in Python. This Jupyter notebook thing that is exactly what I need. And VSCode recently added support for it! The installation instructions for Jupyter are all like “anaconda” and …
We talk about “software products” and “product teams.” What does this even mean, “product?” It is not the definition I learned in school. Economics 101: the output of the economy is “goods and services.” Goods, also called “products,” are physical items that you can buy, take home, and have. Like, if you buy a rug, …
