Practical Versus Theoretical

I am a big believer in personal development and growth. One of the things that often keeps us from growing is lack of awareness. There may be certain ways that we present ourselves or ways that others perceive us that we aren’t aware of. I did an exercise recently

The Problem With Solving Problems

As engineers we pride ourselves on problem solving. That’s what we do. However I find the use of the word problem to be somewhat problematic (pun intended). When we use the word problem, typically we are referring to something that is not working. Often it was working, but for

Dynamic Unloading of Classes

In my previous post, I did a demo of the factory pattern. In it I showed how to dynamically load classes based on their path. One thing you may have noticed in that demo is that the classes stayed in memory even after the Test VI stopped running. If you

Gang Of Four Patterns in LabVIEW

I have written a bit about design patterns previously. Recently Tom McQuillan and I were talking about how it would be nice to have examples on how to implement the GOF design patterns in LabVIEW. To be fair, Elijah Kerry put together some great examples several years ago, but he

Python Adaptor in TestStand

I wrote a recent post about calling Python from LabVIEW. As it turns out you can also call Python directly from Test Stand as well. In TestStand 2019 a new Python Adaptor was added. Rather than create my own example, I will just point you to the shipping example. It’

Docker in Action

Note: for more on Docker itself, see here. Chris Stryker has recently put a lot of effort into getting LabVIEW to run inside of a Docker Container. This is really exciting news. I think this is really a huge step forward in improving Continuous Integration (CI) with LabVIEW. It offers

Undoing A Bad Commit

For our local LabVIEW User Group we have a Slack channel. Someone on there recently asked for some advice about undoing a commit in Git. They were working on a project in LV2019 and someone had accidentally opened it in LV2020, made some changes, and then pushed them to the

The Zen Of LabVIEW

Simple is better than complex. Straight wires are better than bent. We read left to right, let’s wire that way. BD cleanup is often better than a messy diagram. White space is your friend as long as everything fits on one screen. Subvis are also your friends. Use them.

Python node basics

I have been learning a bit about Python lately. I find it a nice complement to LabVIEW. Like LabVIEW it is very good for writing quick little scripts and rapidly prototyping things. Unlike LabVIEW, it is not strictly typed, which makes it rather interesting to me. A few years ago

Workability versus right and wrong

Very early in my programming career, I was very dogmatic. I learned one way to do things and that was THE right way and anyone who didn’t do it that way was doing it wrong. I really wasn’t afraid to tell people that either. Obviously starting with “Your

Automatically Creating A Gitlab Repo

I’ve been working on streamlining some of my processes lately. I noticed that one of the one things that takes a little time is creating a new GitLabRepository. It just seemed like it took too much time. Here are the previous steps 1. Goto GitLab Webpage 2. Login 3.

Changing Git's default branch

What does scalability actually mean?

So recently the question of scalability came up on an NI forum post. Stephen Loftus-Mercer (aka AristosQueue) made a very interesting point. He talked about how scaling can mean many different things to many different people. A solution that is scalable on one axis might not be scalable on another.

Git Reflog
