Building my new business environment started with repurposing an old Dell R620 as a Proxmox host. I quickly noticed, however, that the information that showed up in the system’s iDRAC interface was… wrong.

So this one caught me off-guard. I’m currently working on a project that uses an ESP32-S2, and for expedience I’m working with the Arduino framework. It’s just faster that way, honestly.

Every once in a while, I do something stupid. One of the things I don’t want on this blog is data about my location. The problem is that modern cameras – especially cell phone cameras – include your latitude and …

I’ve been trying to force myself to learn about zsh since Apple switched the default shell (why, Apple, why?!). One of my biggest annoyances has been the unexpected munging of the Meta-Backspace combination.

I’ve been making a number of changes in my local environment (more on that in a few days I think), and I ran across a problem that is, as far as I can tell, fairly undocumented.

Earlier today I was working on a new post – and yes, I’m actually writing new content, and not just about Hugo! But that’s not the point. The point is, I came across an annoyance, and managed to also find a …

When we think of a blog, we typically think of the content – but in practice, we also have to worry about the taxonomies. Tags and Categories, oh my! These are hard enough to manage with a live system like WordPress; how do we do …

While Hugo is overall quite excellent, it does have a few warts, and one in particular was a problem for this site. Sometimes I write fairly long articles, and they don’t really lend themselves well to being a single huge …

I’m currently planning the installation of a structured wiring cabinet, and came across things I didn’t know – like the fact that keystone fiber jacks can be made from a variety of materials. This apparently matters.

If you’ve ever set up DNS forwarding on a Ubiquiti EdgeRouter and have your own internal authoritative DNS servers, then you may have noticed that it doesn’t quite work right. If you look up the hostname of your router via the …
