Problem 1

Use JavaScript to write a function that takes a number as its argument. If the number is less than 10, the function should return "small"; if the number is 10 or greater, but less than 100, the function should return "medium"; if the number is 100 or greater, the function should return "large".

Problem 2

Use JavaScript to write a function that takes a number as its argument. If the number is between 1 and 10 (inclusive), return the word for that number (that is, if the number passed to the function is 2, return the word "two"). If the number is not between 1 and 10, return false.

Install MySQL on macOS Sierra

This procedure explains how to install MySQL using Homebrew on macOS Sierra 10.12

Install Homebrew

Installing Homebrew is effortless, open Terminal and enter :
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Note: Homebrew will download and install Command Line Tools for Xcode 8.0 as part of the installation process.

Install MySQL

At this time of writing, Homebrew has MySQL version 5.7.15 as default formulae in its main repository :

	# Put this in Rakefile (doesn't matter where)
	require 'benchmark'

	class Rake::Task
	def execute_with_benchmark(*args)
	bm = Benchmark.measure { execute_without_benchmark(*args) }
	puts " #{name} --> #{bm}"
	end

	alias_method :execute_without_benchmark, :execute

	create_table :media_items do \|t\|
	t.string :type, :null => false, :limit => 32
	t.string :name
	t.timestamps
	end

	class MediaItem < ActiveRecord::Base
	validates_presence_of :kind
	end

	======= Prolbem =================================================================================================================
	I have installed : ruby-2.0.0,postgres-9.2 , now in rails app when I execute:

	rake db:create , command I get:

	PG::InvalidParameterValue: ERROR: new encoding (UTF8) is incompatible with the encoding of the template database (SQL_ASCII)
	HINT: Use the same encoding as in the template database, or use template0 as template.
	: CREATE DATABASE "my_db_name" ENCODING = 'unicode'.......

	bin/rake:16:in `load'

	Because I couldn't find these with a quick Google search on 28 April 2015:

	Usage:
	rails new APP_PATH [options]

	Options:
	-r, [--ruby=PATH] # Path to the Ruby binary of your choice

	-m, [--template=TEMPLATE] # Path to some application template (can be a filesystem path or URL)
	[--skip-gemfile], [--no-skip-gemfile] # Don't create a Gemfile
