Okay, I’m biased — it’s my task runner — but hear me out. This post will start by discussing what a task runner actually is and exploring how it works by building a very basic version of one in Go code. Then we’ll look at some example tasks that can be completed with the help […]

I want to discuss the recent crypto crash and its potential implications, so I’m going to take a short diversion from my usual approach of providing programming advice and code examples with this post. Understandably, the rapid fall in the valuations of cryptocurrencies is a topic that interests many of us who work in the […]

Sometimes you want to read a file that contains many lines of text or a list of structured data and you want to process each line individually, rather than working with the entire content of the file at once. This post will discuss various ways to read a file line by line, looking first at […]

This post will explain what hash functions are and how they’re used. We will then go on to look at some examples of hashing algorithms in Go code. Finally, we will look at importing external packages that export hash functions, including from the standard library. What Is a Hash Function? A hash function takes data […]

This post will document my very first foray into developing a WordPress plugin, which is used on this website. The majority of the code is contained within a single JavaScript file. Why Do I Use WordPress? The blog runs on WordPress. I’ve created other websites and blogs in the past for which I wrote all […]

Slices are one of the most important data structures used in Go. In this post, we will look at how to concatenate slices. We will start by explaining the general concept of concatenation, then we will look at examples of concatenating two or more slices in Go. Finally, we will build functions that can help […]

This post will discuss the various ways to add elements to a slice. Appending an element adds it to the end of the slice, whereas prepending it adds it to the beginning of a slice. It is also, of course, possible to add an element at any position in between. We will finish by looking […]

When an image is pixelated, it has a visual effect applied to reduce its level of detail through the use of many same-sized blocks, each painted with a single colour. Each of those blocks can be thought of as a large pixel (since a pixel is the smallest unit that can contain a colour in […]
