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 […]
The Ebiten game framework was written by Japanese software engineer Hajime Hoshi. The framework is designed to make it easier for Go programmers to create native-looking 2D games, by taking care of all the boilerplate code for us. (Note that since I first wrote this post, Ebiten has been renamed to Ebitengine.) Installing the Ebiten […]
It’s been a long time coming and it’s caused a certain degree of controversy among Gophers, but now we know, at last, that it’s really happening. Generics have been included in a beta version of Go 1.18, which was just released this week. What Are Generics? In a strictly typed language like Go, every argument […]
Every serious software developer or system administrator must have at least a basic grasp of Bash commands, because they can often help you to manage computer systems much more efficiently and effectively than if you were only to use a point-and-click GUI. In this post we’re going to write Go code that will aim to […]
In this post, I am going to show you how to transform a full-colour image into one made up entirely of different shades of grey. The sort of image that we will create is called greyscale, because every colour that makes up the image is stored as a position on a predetermined scale of greys […]
