The Myers diff algorithm

The following based on Myers' original paper.

The edit graph

To use the example from the paper, say you want to calculate the difference between two strings:

rlburkes

# Wouldn't it be great if you could have STI like functionality
# without needing to encode strings of class names in the database?
# Well today is your lucky day! Discriminable Model is here to help.
#
# Simply specify your models desired type column, and provide a block to
# do the discrimination. If you want the whole STI-esque shebang of properly
# typed finder methods you can supply an array of 'discriminate_types' that will
# be used to apply an appropriate type.
#
# class MyModel < ActiveRecord::Base

# speed up pluck

class ActiveRecord::Relation

  class RailsDateTimeDecoder < PG::SimpleDecoder
    def decode(string, tuple=nil, field=nil)
      if Rails.version >= "4.2.0"
        @caster ||= ActiveRecord::Type::DateTime.new
        @caster.type_cast_from_database(string)
      else

An ActiveRecord conundrum

I'm going to describe a weird problem I faced when using ActiveRecord today. To protect the innocent, I'm not going to talk about the app I'm actually working on but will instead discuss a hypothetical but isomorphic database design for a clone of the popular blogging platform Tumblr.

Tumblr lets you publish various different sorts of content. We might be tempted to shove all these types in a big STI table, but the types are all quite different from one another and so we give them their own tables.
