Indexing

By default, simply adding the call 'searchkick' to a model will do an unclever indexing of all fields (but not has_many or belongs_to attributes).

In practice, you'll need to customize what gets indexed. This is done by defining a method on your model called search_data

def search_data

Programming Achievements: How to Level Up as a Developer

While attempting to explain JavaScript's reduce method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.

Intro

JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return a new list - thus making it much simpler to think about both the old list and the new one, what they contain, and

	#!/usr/bin/env ruby
	require 'io/console'

	class Grid
	def self.from_str(str, color:)
	rows = str.lines.map do \|line\|
	line.chomp.chars.map do \|c\|
	color if c != " ".freeze
	end
	end

	SELECT
	'https://stackoverflow.com/questions/' + CONVERT(VARCHAR, Posts.Id) as url,
	(
	ViewCount / (SELECT -DATEDIFF(DAY, GETDATE() , CreationDate))
	) AS ave_views_per_day,

	ALPHABET_SIZE = 26

	def caesar_cipher(string)
	shiftyArray = []
	charLine = string.chars.map(&:ord)

	shift = 1
	ALPHABET_SIZE.times do \|shift\|
	shiftyArray << charLine.map do \|c\|
	((c + shift) < 123 ? (c + shift) : (c + shift) - 26).chr
