Go and Ruby
summary
Compares concrete Go features to Ruby: shows gotest benchmarks that auto-scale to ~1s runs, uses CGO to wrap SQLite and demonstrates embedding the Ruby VM, builds a reflection-based duplicate and a raw memory package that lets slices map to arbitrary bytes (uses unsafe pointers and a 4KB goroutine stack), implements panic/recover catch, and models CSP-style channels with map-reduce and a chat server; most demos compile and run, and the talk highlights 13 base types and ~134 contributors to the Go repo.
