# Sum all the digits
# Write a program that takes a positive number as an input.
# The program should take every single digit of this number,
# and sum them until only a 1 digit number is left.
# Example input: 31337
# Output: 8 (because 3+1+3+3+7=17 and 1+7=8)

Metaprogramming Ruby - Access anything
# Ruby as a particularly flexible language which provides developers a rich toolbox
# to express any source code in several different ways.
# Reading "Metaprogramming Ruby - Program Like the Ruby Pros" (The Pragmatic Programmers)
# I wanted to try my self many of the different `spells` (as Paolo calls them)
# I learned or learned its formal definition.
# Knowing how to use these tools becomes crucially useful as
# we'd often like a slight modification of the behaviour of an external gem.
# In this case we can either send a pull request to the owner

# Instead of monkeypatching globally methods
# it is possible to `refine` methods
# so you know where a method is coming from.

# Elastic search grouping solution
# As at present ElasticSearch does not provide a group_by equivalent, here's my attempt to do it manually.
# In the example we have articles made by some authors and I'd like to have relevant docs, but not more than one per author.
# Assumption.
#
# 1) I'm looking for relevant content
# 2) I've assumed that first 300 docs are relevant,
# So I consider only this selection, regardless many of these are from the same few authors.
# 3) for my needs I didn't "really" needed pagination, for me it was enough a "show more" button updated through ajax
