The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

A simple rake task that replicates the rails console for Lotus Framework

I assume that your config/application.rb is the place where you initialize all Lotus boot config

below is my config/application.rb for your interest

and compile the decision tree.json

ruby compile.rb

It's common in Ruby to see some code setup a Struct like this:

class Specialized < Struct.new(:whatever)
  # ... define custom methods here...
end

	= semantic_nested_form_for @gallery, multipart: true do \|form\|
	= form.input :file_multiple, as: :file, input_html: { multiple: true }

	= form.actions do
	= form.action :submit

	# An example demonstrating Gmail API via IMAP using gmail_xoauth gem
	# Add this file to your rails project to use if you don't want to use this in rails project then require
	require 'net/imap'
	require 'gmail_xoauth'

	class Gmail
	attr_accessor :email, :access_token

	def initialize(args)
	email = args[:email]

	def paginate(scope, default_per_page = 20)
	collection = scope.page(params[:page]).per((params[:per_page] \|\| default_per_page).to_i)

	current, total, per_page = collection.current_page, collection.num_pages, collection.limit_value

	return [{
	pagination: {
	current: current,
	previous: (current > 1 ? (current - 1) : nil),
	next: (current == total ? nil : (current + 1)),

	source "https://rubygems.org"

	gem "pg"
	gem "sqlite3"

	unless version = ENV["AR"]
	abort("specify ActiveRecord version with AR. eg: AR=2 bundle install")
	else
	gem "activerecord", "~> #{version}", require: "active_record"
	end
