Hi David - Thanks for the video. A quick thought on the '99_summary.rb' snippet - Instead of using 'ActiveRecord::Base.descendants' and excluding the non-application models, wouldn't it be easier to use 'ApplicationRecord.descendants' ?

Thanks Dave. As informative as ever.

A trivial typo in config.ru -

hash[:password] == password

Hi David, Loved the episode. Really nice job covering the topic in 20 odd minutes.

One minor observation in Game::Turn#call, the fallback 'else' will never be reached, since we apply `to_i` on the `guess`. We will be sending a misleading reply back in case a non-numeric input is passed.
