In this post I will elaborate on what I think is a good practice on maintaining your source code as the project grows. The why Over the (short) period…

Code can be found here: Github repo The looks of the application Programming What we want to achieve with the application is that we can specify a github repository url somehow and display x amount of issues in a…
Introduction In this tutorial we are going to build a simple identicon generator in Go. The source code can be found here: Github repo . But what exactly is an Identicon? I think most of you are familiar with the standard logo you get when creating a new account on Github. Example: What you see here is a visual representation of a hash value. What this basically means is that a input is hashed…
