A case for sets

Back in LabVIEW 2019, NI introduced both sets and maps. Maps became immediately popular. They should be. They are very useful constructs. However, sets seem to have gotten much less attention. In some ways, they aren’t as glamorous, but they do offer some advantages over arrays. To me, these

Forget the word but

In improv, there is this idea called “yes and”. The idea is that the first person goes and starts telling a story. The second person (and everyone after them) picks up with “yes and” and then continues adding to the story. What you want to avoid doing is using the

The Freedom of Refactoring

Let’s talk about software design and refactoring in LabVIEW. When I first read Martin Fowler’s Refactoring book several years ago, it was very liberating. Prior to that, I had always had the idea that I had to get things right up front. It was kind of paralyzing. I

Quick VI Analyzer

GitLab CI and Git Bash

A while back GitLab CI deprecated the batch executor for Windows runners. That meant that you could no longer directly call batch scripts from a Gitlab Runner. They had switched over to Powershell. There were workarounds. You could still write a batch script and call it from PowerShell using cmd.

Informative Versus Transformative Learning

In the technology field, particularly programming I feel like we tend to focus a lot on informative learning. Informative learning is just building upon what you already know. For instance, if you already know how a for loop works in C, and then you learn how to implement it in
