Go docker-compose deployer allows multi-stage docker deployments and eases the management for you.
Auto-scaling and self-defensive services in Golang
The Raygun service is made up of many moving parts, each specialized for a particular task. One of these processes is written in Golang and is responsible for desymbolicating iOS crash reports. You don’t need to know what that means, but in short, it takes native iOS crash reports, looks up the relevant dSYM files, and processes them together to produce human readable stack traces.
Converting Character Encodings In Golang
At one point or another, every developer gets stuck converting a pile of files from one character encoding to another. Go's native character set is UTF-8, and the core Go libraries don't come with tools for converting character sets. However, one of the Go extension libraries makes this easy.
Why Go Interfaces are Awesome
In object-oriented programming, an “interface” is a description of the things an object can do. Usually, this takes the form of a list of methods an object is guaranteed to have. C# and Java both support interfaces, and so does the Go programming language, but Go’s interfaces are especially easy to use.
Mocking dependencies in Go
We all use a lot of packages when constructing our applications, both internally developed and third party packages. This blog post will show how you can easily mock these packages using mockery and stretchr/testify/mock.
SFTP deployment, backup, and download programme
Created to serve the need for uploading, downloading and backing up website code for WordPress sites which only support SFTP access. Backup routine saves files to .tar.gz file without intermediate step of saving remote files locally and then tarring that folder. Upload will take configured folders and upload to designated spots in the remote system. Download will do a similar but reversed operation to the upload. Each step is configurable in terms of the local and remote locations to act upon. Integrates with SSH Agent or Pageant (on Windows) for SSH Key-based authentication, but also supports Password authentication as a fallback.

Leveraging Interfaces in Golang - Part 1
In my previous blog post on using golang in production, I have mentioned that interfaces are my favorite feature in golang.
As a follow-up of this comment, I would like to share how we are using (my current project is also in golang!) the interfaces to keep our code clean and consistent through a series of three blog posts This blog post series assumes that you are familiar with the basics of interfaces in golang. If would like to know what it brings to the table, I strongly recommend to check out this well-written article by Yan Cui.
playgo - a real playful Golang playground
This is the simple version of Go Playground it runs locally with no container needed.
Custom imports can be used.
JSON References
Chances are that if you have not had to deal with JSON data yet, you will. This is a collection of articles and talks that explain how to use encoding/json or one of the other JSON packages.
Elvish - a sophisticated shell implemented in Go
Release 0.9 has just been announced (here and here and here) and to me it already looks quite mature and really promising. One key feature is that pipelines can pass not only text but also other data types like lists, maps, or functions.
(Available on macOS and Linux via Homebrew/Linuxbrew: brew install --HEAD elvish. Currently, without --HEAD, brew installs v0.8.)
