Sound and audio hardware was probably one of the more complex and irritating elements of DOS gaming in the early 1990s. So many choices, incompatibilities, and even different advantages for sound effects, speech, or music. So what do you choose today when an emulator like DOSBox gives you so many audio choices?

I will go through the easy process of optimizing images in Hugo to create <img> elements that represent good practice. It will cover recommended attributes, image compression, the automatic generation of alternative formats, and cache busting using fingerprint.

Importing my WordPress Export XML document to import.disqus.com fails with the unhelpful error.

XML syntax error: attributes construct error, line 21, column 66 (line 21)

In this post, I will create a simple function that will allow you to ask the user a question, receive a valid response, and return it as a Boolean type. And if needed, the user will be able to tap Ctrl+C at any time to exit the program. Also importantly, despite using the operating system input, we will create unit tests for os.stdin.

This article will go through creating byte unit methods for both metric and binary prefixes. The two stringers will take a float64 value and round it with a metric unit.

• Decimal(15000).String() returns 15.0 kB
• Binary(15000).String() returns 14.6 KiB

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.
