Comments on: Memo #5: Use ary.uniq method carefully in Ruby https://kpumuk.info/ruby-on-rails/memo-5-use-ary-uniq-method-carefully-in-ruby/ In my blog I'll try to describe about interesting technologies, my discovery in IT and some useful things about programming. Wed, 30 Sep 2009 17:12:32 +0000 hourly 1 https://wordpress.org/?v=5.2.2 By: roger rubygems https://kpumuk.info/ruby-on-rails/memo-5-use-ary-uniq-method-carefully-in-ruby/comment-page-1/#comment-283328 Wed, 30 Sep 2009 17:12:32 +0000 http://kpumuk.info/?p=721#comment-283328 So was this fixed for 1.8.7 at some point then? [between p72 and p174]?

I slightly modified your script:

1
2
3
p [{"id"=>667824693}, {"id"=>667824693}].uniq
p [{"id"=>66782469}, {"id"=>66782469}].uniq
p [{"id"=>6678246931}, {"id"=>6678246931}].uniq

And ran it with multiruby:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
