For us to be able to write small focused unit tests, we need to be able to draw the right boundaries. In this post, I will go over what this looks like conceptually, and then I will walk through a more concrete but somewhat imperfect example.
Continue readingIf you ask most software engineers what some of the worst parts of their jobs are. Then chances are estimates will fall somewhere in the top 3. Followed closely by tech debt.
So why are estimates so difficult?
And why do most well-intentioned projects, accumulate so much tech debt?
Continue readingThis post will be centered around how we can test time-related aspects in Python.
Continue readingIn this post I will talk about the Kubernetes Horizontal Pod Autoscaler.
I will go over the concepts behind it and why we might want to use it.
I have never considered myself to be a particularly high level engineer. And I doubt I ever will.
To help me understand, I know that I have to write code with the right abstractions in place. They allow me to convey my thoughts to the reader. A lot of the time, that reader is myself at some point in the future!
Continue readingIn this post I will about the Kubernetes Cluster Autoscaler.
I will talk through some of the key concepts and why it plays an important role in our clusters.
Modern applications experience fluctuating demands based on a variety of factors.
Scalability describes the flexibility of a system in the face of ever-changing demand.
In this article, I will unpack some of the core concepts of scalability to give us a starting point
for some of the more nitty-gritty details of scaling.
This post will highlight a not-so-desirable feature of Helm that has stung me before. I hope you don’t repeat my mistakes after reading this!
Continue readingIn this post I will talk about a bugbear of mine that I’ve had over the years.
This relates to returning None from functions and methods in Python.
In this post, we are going to discuss a URL-constructor function.
More specifically, we are going to highlight a common pitfall encountered when constructing strings for URLs.
