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.
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.
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.
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.
High-performance, scalable and reliable IPFIX, sFlow and Netflow collector.
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.
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.)

This site is built using the awesome web framework Buffalo created by Mark Bates. It's been amazing learning the framework coming from Rails background and having Mark help me every step of the way. Have fun and contributions are most welcome :)
What are Goroutines?
Goroutines are functions or methods that run concurrently with other functions or methods. Goroutines can be thought of as light weight threads. The cost of creating a Goroutine is tiny when compared to a thread. Hence its common for Go applications to have thousands of Goroutines running concurrently.
Since we began our transition from Scala to Go, we discovered that when there's no right tool for the job, we can make a rough one ourselves in an hour or two. If it makes sense we can iterate on it until it becomes something the whole team can use, then the whole company, and then, sometimes, the whole world.
In this blog post, I'd like to share two of these tools: sql and chart, that we've been using a lot lately. Together, they compose an interesting pattern for tinkering with multiple databases individually or concurrently within the terminal.
