Arrays, Slices and Maps in Go -Go 101
Three new books, Go Optimizations 101, Go Details & Tips 101 and Go Generics 101 are published now. It is most cost-effective to buy all of them through this book bundle in the Leanpub book store. Strictly speaking, there are three kinds of first-class citizen container types in Go, array, slice and map. Sometimes, strings and channels can also be viewed as container types, but this article will n
Different approaches to HTTP routing in Go
July 2020 Update March 2024: Go 1.22 shipped with significant enhancements to the standard library’s http.ServeMux router. You can now specify patterns with a method and path variables, such as mux.Handle("GET /{slug}/admin"), and I’ve updated the code. For new work I’d recommend you ignore this article and use the standard library! There are many ways to do HTTP path routing in Go – for better or
Containers the hard way: Gocker: A mini Docker written in Go
They are popular and they are misunderstood. Containers have become the default way applications are packaged and run on servers, initially popularized by Docker. Now, Docker itself is misunderstood. It is the name of a company and a command (a suite of commands, rather) that allow you to manage containers (create, run, delete, network) easily. Containers themselves however, are created from a set

Create a PKI in GoLang
 June 5, 2017 Lately I have been programming quite a bit and - for the first time - I have used Golang doing so. Go is a very nice language and really helped me with the development. One of the reasons why I have enjoyed this much Go is the standard library, which is amazing. I would like to share today the easiness of creating a basic Certificate Authority and signed certificates in Go. Create a
