Go for Rubyists
summary
Go claims faster builds and simpler concurrency than Ruby, with origins in 2007, open source 2009 and a 2012 release, and adoption at YouTube, Netflix, Let's Encrypt and Globo. A concrete health-check service gets implemented: it queries many dependencies in parallel using goroutines and channels, returns errors via the two-value idiom, uses go dep / go get and GOPATH, compiles to a single Linux binary and runs in Docker — the demo compiles cross-platform and the parallel checks work.
