ruby on rails - Include or extend a class/module from a gem (e.g. devise) -

-

i have written small module lib/encryption/encryption.rb 

module encryption   def self.encrypt(value)     ...   end    def self.decrypt(value)     ...   end end

i want use/access module in these 2 files devise, namely:

  1. token_authenticatable.rb
  2. authenticatable.rb

i have overwritten both of them creating 2 new files , putting them /config/initilaizers (copied original source code within them , modified them)

  1. /config/initializers/token_authenticable.rb
  2. /config/initializers/authenticatable.rb

one file looks instance:

require 'devise/strategies/token_authenticatable' require './lib/encryption/encryption.rb' #tried this, not work  module devise   module models     # tokenauthenticatable module responsible generating authentication token ,     # validating authenticity of same while signing in.     ...

my modifications work, how can access lib/encryption.rb module within these files? modification approach best practice? if not, right approach?

if have in application.rb:

config.autoload_paths += %w(#{config.root}/lib)

then '/lib' autoloaded. meaning can call

require 'encryption/encryption'

and should work.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
