Introduction Knowing the type of a file you’re working with is not just a matter of curiosity — it’s often a necessity. This is especially true when you’re deciding whether or not a particular operation can be carried out on that file. Go, with its comprehensive standard library, offers a straightforward approach to identifying a file’s MIME type, ensuring that developers have the tools they need to make informed decisions about file manipulation.

Introduction In this post, we’ll take a quick look at URL validation using Golang. It’s common to implement URL validation as a task within a HTTP request pipeline, typically as middleware. There are many different definitions of “validation”. For the purpose of this article, we will simply validate that a URL conforms to a particular text pattern. I often see people (mistakenly) use URL and URI interchangeably. URL is actually is a sub-type of URI.

This will be a short post about a recent issue I encountered when using Nginx as a Kubernetes ingress. Though, this could also be encountered when using Nginx as a reverse proxy as well. The two definitions are functionally similar. We recently had a client call in complaining of our application returning random 502s (Bad Gateway). After some investigation and the common finger-pointing, I found this entry in the logs of our ingress controllers:

Introduction Netcat is a versatile networking utility that can be used for a wide range of tasks. It has often been referred to as the “network swiss-army knife”. Netcat was first released in the mid-90s, and I personally find it ironic to be blogging about it in 2023! But I feel like it is a somewhat cryptic tool, and new engineers or college graduates may not be familiar. This article is meant for those people who are not familiar with it, or have only briefly been exposed.

Despite being a great language, PowerShell is not impervious to errors. Errors that occur within your code can stop it’s execution or even cause unexpected changes in the resources that your script is managing. Learning to handle these errors gracefully is the foundation of defensive coding. Today, we’ll take a quick look at how PowerShell handles errors with Try-Catch-Finally blocks. They allow you to gracefully handle errors and perform cleanup operations, ensuring that your script doesn’t crash when the unexpected occurs.

This will be a quick and dirty post, so please forgive any spelling/grammar mistakes. I was writing a little CLI tool in Golang to track todo items. Just a dumb little app to help hone my skills a bit, but still something useful that serves a purpose to me. I don’t write a ton of code at work (mostly just scripting/pipelines when I do), so I’m constantly working on something like this in my spare time.

I was recently involved with troubleshooting some API’s hosted in Kubernetes throwing http/502’s. This was incredibly difficult to diagnose because it seemingly happened at random, and I had never encountered anything like this. Being that I had never dealt with this in the past, and I (nor my team) was able to figure it out within a reasonable amount of time, I turned to google. My searches resulted in various blogs and SO posts of other people experiencing similar issues, but none of their resolutions worked for us.

I’m not really a fan of photography. I don’t particularly enjoy the intracies of tuning a high-end DSLR camera. Nor am I a fan of being out in nature to photograph a fall sunrise (though, that does sound peaceful). However, I do take a lot of pictures with my phone (currently, a Pixel 6). Moreso now that I am a new father. I am protective of these photos. So much that I sync them automatically from my phone to two cloud storage providers.

In this article, we’ll take a quick look at building a Golang app with Github actions. This process can be applied to just about any app written in any language though. We’ll cover the following: What are github actions? Setting up the workflow to build, test, and deploy a binary Github Actions is a cross-platform CI/CD pipeline that allows you to build, test, package, and release your software. Actions can be triggered manually or based on events that happen within your Github repo.

In this article, we’ll take a quick look at chaining two pipelines together in Azure Devops, so that the completion of one pipeline, triggers the other to run. Microsoft documentation is leaps and bounds ahead of where it used to be. However, I still feel like there is a lot of room for improvement, as it took me a while to figure this out. Our two pipelines will exist in the same repository.
