Ruby Vs. The World
summary
Compares Ruby with Go, Clojure and Scala, demonstrating concrete tradeoffs: Go uses goroutines and channels to fetch three URLs concurrently without locks; Clojure excels at data processing but exposes meaningless stack traces and a steep namespace/function learning curve; Scala powers service-oriented systems (Twitter’s Finagle) with Futures/pipelines and shows 2–50x faster benchmarks vs Ruby. Recommends practical changes to Ruby coding: prefer explicit return value plus error handling, lean toward immutability, and use typing/compilers to simplify and speed code.
