instance method Module#prepend (Ruby 2.0.0)
prepend(*modules) -> self[permalink][rdoc] 指定したモジュールを self の継承チェインの先頭に「追加する」ことで self の定数、メソッド、モジュール変数を「上書き」します。 継承チェイン上で、self のモジュール/クラスよりも「手前」に 追加されるため、結果として self で定義されたメソッドは override されます。 modules で指定したモジュールは後ろから順に処理されるため、 modules の先頭が最も優先されます。 また、継承によってこの「上書き」を処理するため、prependの引数として 渡したモジュールのインスタンスメソッドでsuperを呼ぶことで self のモジュール/クラスのメソッドを呼び出すことができます。 実際の処理は modules の各要素の prepend_features を後ろから順に呼びだす

Using Arel to Compose SQL Queries
Rails gives us a great DSL for constructing most queries. With its knowledge of the relationships between our tables, it’s able to construct join clauses with nothing more than the name of a table. It even aliases your tables automatically! The method we most often reach for when querying the database is the where method. 80% of the time, your query will only be checking equality, which is what wh

Debugging memory leaks in Ruby
Sam Saffron Programming, Technology and the Art of Hacking At some point in the life of every Rails developer you are bound to hit a memory leak. It may be tiny amount of constant memory growth, or a spurt of growth that hits you on the job queue when certain jobs run.
