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 […]
It’s reasonable to look at a picture and to wonder how it might look if it were distilled down into a single colour, which somehow still encapsulates a sense of the original. In this post, we will look at various methods that can be used to calculate the average colour of an image in Go, […]
For the past six years, Google has run an annual Go Developer Survey in order to understand more about what the community thinks and how it feels about recent changes to the language. The survey also helps to keep us informed about any problems or concerns that have arisen and gives us an opportunity to […]
I’ve written in the past about how to reverse the order of all the elements in a slice, but today I’m going to discuss some of the ways that elements can be removed — in other words, deleted — from a slice in Go. When looking at the various ways to remove one or more […]
No matter how many programming languages you learn, you will almost certainly never know them as well and as instinctively as your natural language. Even though it may not always seem to be the case when you’re dealing with a difficult programming problem, the English language is much more complicated than Golang: its vocabulary is […]
Have you ever been watching a video and wanted to download it, so you can watch it again offline or on another device? I’m going to show you something that should be able to help you do just that: Lux is a really handy little command-line application that has been built in Go and it […]
In any programming language, there are two main algorithms used for finding a given value in an array: linear search and binary search. (Just to note: in Go, we generally use slices rather than arrays, but I’ll use those two terms interchangeably in this post, just for the sake of simplicity, since everything that I […]
If you’re building a web app or program that handles sales from customers, you may need to find a reliable way of representing money in Golang. There’s no single way to do it, since the language does not have a primitive type that is intended to hold monetary values. In this post, I will go […]
