GoLang, often referred to as Go, is a statically typed, compiled programming language designed by Google. It has gained significant popularity among developers due to its simplicity, efficiency, and robustness. In this blog post, we will explore GoLang’s best features from both performance and development perspectives, backed by comprehensive code examples to illustrate these advantages.

Hey everyone,

Today, I want to dive into Go language and talk about interfaces, with a specific focus on generics. Generics have been one of the most highly anticipated features in Go, and they are finally here with the release of Go 1.18. Let’s explore how interfaces and generics work together in Go and how they can make our code more flexible and reusable.

Recently I came across an interesting problem. I had to install kernel from branch 3.10 on CentOS6 and there was a need to update grub.conf - change default kernel plus add boot option. Both mentioned operation had to be done in Puppet 3.7 (Augeas are of course also available in the higher version of Puppet). Sounds easy right?
