To make this discussion really useful: what's the easiest way for a Ruby application to make SecureRandom use /dev/urandom, without waiting for Ruby-core to be convinced?

require "securerandom" module SecureRandom F = File.open("/dev/urandom") def self.random_bytes(n = nil) F.read(n || 16) end end

  Why not just make the argument default to 16? Is something non-obvious going on?
  - infraruby 11y ago
    The caller may pass nil explicitly.
    - goldbrick 11y ago
      I don't understand. You may still pass nil explicitly if the argument defaults to 16?
      - infraruby 11y ago
        Yes: def f(n = 16) n end p f # => 16 p f(nil) # => nil
