In this talk, I will present how to extend your Ruby code with Golang. Since Go 1.5, you can build C compatible binaries by using buildmode c-shared/c-archive. This is a very exciting feature for rubyists. First, I'd like to show you how to use Go code from Ruby with FFI and fiddle. Then, I will talk about how to build gems with Golang.
