When faced with a potential latency issue in web services, this is often one of the first commands I run several times from multiple clients because the results form this command help to get a quick sense of the layer that might be responsible for the latency issue.

I've been using Bash functions quite liberally over the past couple years, but last week I discovered that they can be much better than I thought. In this post, I'll explain how I thought they worked, why I was wrong, and how that makes them better.

Title of this blog post isn’t a collection of every Kubernetes related buzzword I could think of. It’s a collection of technologies that went into creating an automated, resilient and scalable WordPress setup.

I was having a problem at work with an ARM64 Linux edge device. I have an ARM64 binary on the edge device, and I wanted to look at which dynamic libraries it is linked to with the readelf program. Unfortunately, readelf is not installed on the device. I was unable to figure out how to use the device's package manager.

I was able to build a readelf binary that I could use on the device by cross-compiling and statically-linking one from Nixpkgs. This post explains how to easily cross-compile and statically-link packages from Nixpkgs.
