This guide will show how simple it is to center text in a terminal or a text file using the Go standard and external libraries. We will create two functions, NCenter, which provides for a width parameter, and a Center func that will determine the center placement based on the width of the terminal screen.
You can find the final code on GitHub or play with NCenter() in the Go Playground.
One of the great things about the Go standard library is how easy it is to create a sophisticated tool using a small amount of code. In this entry, I will explain how to make a variable-length random string generator that can support any Unicode character.
You can find the final result on GitHub or run it at Go Playground.
Go is a strongly typed programming language, and many SQL databases also support unknown values. These unknowns can lead to complications in Go. Such as in this example, when a NULL value is in use for an empty string, it throws the unhelpful error converting NULL to string is unsupported.
In this guide, let’s go through the process of installing and configuring WordPress on a Docker container using docker-compose. The primary goals are to install a bare-bones install with the ability to customise wp-config.php, php.ini and my.cnf. There is an expectation that you are familiar with Docker, WordPress, PHP and MySQL configuration files.
I have a Ubuntu 18.04 LTS server running ufw (Uncomplicated Firewall) and Docker. Docker relies on iptables-persistent, an interface to a much more powerful and complicated firewall that many people would rather avoid.
