At my first real job, around the turn of the millenium, software engineers were graded on a bell curve. On a scale of 1 to 5, most people should get 3s, with a lower number of 4s and 2s and a much lower number of 1s and 5s. The bell curve, also called the normal …
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, …

For instance, I wanted to receive traces over HTTP/JSON from this sneaky browser extensionLINK and send them to Honeycomb. …
TL;DR: When different parts of an organization need to coordinate, it seems like a good idea to help them coordinate smoothly and frequently. Don’t. Help them coordinate less — more explicitly, less often. Software systems get big, and they have lots of parts, and those parts need to talk to each other. Maybe we’re building …
TL;DR: Projects ask teams do what is asked of them; Products ask teams to invent their work. This requires a different way of seeing the world, and not everyone can do it yet. Software is not an up-front investment that pays off over its use. Software is an ongoing concern, an intricate piece of a …

What is happening in production? Distributed tracing can help you find out. But it’s one thing to instrument, another to use it. Here’s a short (6m) video that asks “Why is this so slow?” See three quick ways to get answers in Honeycomb. If you want to follow along and play with the same data …
Just now, Avdi had a miserable experience buying curtains. He went to pick up an order that he placed last night, but Lowe’s didn’t have it. The order was sent to the wrong store and it was a huge pain to figure out. Software is hard to get right. And every time we don’t, customers …
