After developing Glow last year, I came to realize the two limitations of Go for distributed data processing. First, generics are needed. Of course, we can use reflection.
Go 1.8 introduces a new profile, the contended mutex profile, that allows you to capture a fraction of the stack traces of goroutines with contended mutexes. You need to set the sampling fraction by calling runtime.SetMutexProfileFraction to a value above zero to enable collectio...
Back when crypto/tls was slow and net/http young, the general wisdom was to always put Go servers behind a reverse proxy like NGINX. That’s not necessary anymore!
Advanced Encoding and Decoding Techniques Go’s standard library comes packed with some great encoding and decoding packages covering a wide array of encoding schemes. Everything from CSV, XML, JSON, and even gob - a Go specific encoding format - is covered, and all of these...
Go is often the tool of choice for building the guts of a high-performance system, but Go was also designed with some features that are great for building high-level abstractions.
Dave Cheney covered how interfaces are used to design good Go code in his SOLID Go Design talk and blog post. In this blog post, we are going to focus on some tips on how to write unit tests for that beautiful SOLID code.
So far we’ve seen different ways to use Go to build a variety of applications, from versioning your data pipelines to building your own BBQ grill controller.
Go 1.8 will set a default GOPATH if the GOPATH env variable is not set. The requirement of setting a GOPATH has been a major issue for Go users who installed the Go tools for the first time and got the “you have to set a GOPATH” error in their initial experience with...
