moving cron expressions up the taxonomy So cron expressions are a basic aspect of linux computing, and you’ll see them in all the major public cloud providers (AWS/Azure/GCP) for running things on a schedule. They’re useful to know, and once you’ve actually used them, they’re fairly straightforward. Well…AWS and Azure both use special syntaxes that are non-standard, but I […]

More Authentic Parsons Problems

Asking learners to organize code blocks that have been shuffled around is an approach often referred to as Parsons Problems. There is an excellent short rationale for them, and also a more in-depth research study (along with various other online sources) if you’re interested in reading more. The general idea is that there is a […]

Git Submodules, the Forbidden Art

So git submodules aren’t really all that complicated, but because they’re wrapped in mystery and intrigue (much like rebase and reflog), they tend to be a bit less well understood. As any long-time readers of this blog will immediately guess, I’m going to say that’s mostly because submodules are merely unfamiliar, rather than being complicated. […]

TechEd and IP Addresses

I’m starting to move more into the area of tech-focused micromaterials, and this is part of a large shift towards a focus on TechEd. Does that term already exist? I googled around a bunch and couldn’t find any association with the way I’m using it, so I’m just gonna keep using it until somebody is […]

Computers like words too!

This isn’t about a micromaterial per se, but more about the data used to create micromaterials. I was reading an excellent blog post about word lists, and wondered how many of them were accessible in formats other than excel spreadsheets. I soon found out that a lot of them were actually in pdfs (notoriously difficult to […]

A Visual Math Micromaterial Thinking about different ways to manifest micromaterials, I decided to make one that would have helped me a bunch, back when I was learning about simple linear equations. The definition of a linear equation: y = mx + b is simple enough…but what does it really mean? Understanding that the “m” is equal to […]
