Few Questions on Ruby

[Anil Bhat]

Given this module definition:

module Greeting
def say_hello
puts "Hello, my name is #{self.name}"
end
end

1.) How to implement a class Foo using the Greeting module so that the
following code example generates the expected output. Do not implement a
say_hello method.
foo = Foo.new("Fred")
foo.say_hello
2.) How to Implement a class Bar using the Greeting module so that the
following code example generates the expected output. Do not implement a
say_hello method.

Bar.say_hello

3.) Given this class:

class Example
@name
end

How would you describe the @name variable? Assume you have access
to this source code but can't change it. How would you add methods to
the Example class to set and get the value of @name?
4.) In a Rails application, if it takes a long time for a page to load.
If there is an action that dynamically generates a large binary file and
sends this to clients via send_data. How is this related to the slow
response time? What change can we make to avoid this?

Hello,

1)
module Greeting
def say_hello
puts "Hello, my name is #{self.name}"
end
end

class Foo
attr_accessor :name
include Greeting

def initialize(name)
@name = name
end

end

2)
class Bar
extend Greeting
end

3)

class Example

attr_accessor :name

end

4) Client waits until request finishes even if client doesn't download
any data. Implement a background service to generate large files,
implement user notification service to notify user after file is
generated and ready to use.
