This week, we're updating our course layouts and descriptions. Presentation and materials always gently change over time, but just occasionally there's a need to make a step change to clear out some of the old and roll in the new. That's now happening - but over a long and complex site it's not instant and you'll see sections of the site changing up to and including 19th September.

Standard methods available on all objects in Ruby
There are a lot of things I can do with any object in Ruby - there's a whole package deal of methods available to me by just defining and creating an object:
irb(main):003:0> class Thing
irb(main):005:0> widget = Thing.new
=> [:nil?, :===, :=~, :!~, :eql?, :hash, :<=>, :class, :singleton_class, :clone, :dup, :initialize_dup,
:initialize_clone, :taint, :tainted?, :untaint, :untrust, :untrusted?, :trust, :freeze, :frozen?, :to_s, :inspect,
:methods, :singleton_methods, :protected_methods, :private_methods, :public_methods,
:instance_variables, :instance_variable_get, :instance_variable_set, :instance_variable_defined?,
:instance_of?, :kind_of?, :is_a?, :tap, :send, :public_send, :respond_to?, :respond_to_missing?, :extend,
:display, :method, :public_method, :define_singleton_method, :object_id, :to_enum, :enum_for, :==,
:equal?, :!, :!=, :instance_eval, :instance_exec, :__send__, :__id__]
Question from last weeks course - But what do all of these DO?
Answer - I've added a list which describes most of them [here]
