A generic approach to check if an element is present in an array/slice — A few days ago I needed to check if an array contains a specific value. Normally this is a simple task and you can use a predefined function from the programming language itself. In Go, unfortunately, you have to create it yourself. But don’t worry. Today we’ll build a function…

Today we’re going to talk about a small improvement that can make our node pipelines much faster. A few days ago I came across an npm command I had never read or heard of. Until then, I used npm install to prepare the environment with all dependencies in my continuous…

Today we delve into the depths of the git storage system. The memory functionality of git is not as difficult as you might think, but it’s still hard to understand for the time being. In my opinion, the best way to understand is not to use the lift, but to…
