Object-orientation

There are many articles and discussion threads on the web regarding the nature of Object-oriented (OO) programming. Most of them come at the question from a Programming Language Theory (PLT) perspective, attempting to assert a formal definition of OO programming and objects. I'm not going to do that here. Instead, I'm going to write about objects from an implementation perspective, approaching the subject first from below and then from above.

Git Process

Overview

Reserve the master branch for production, staging, and hotfixes
Write new code on a feature branch
Rebase feature branches onto master as often as reasonable
Merge feature branches into master with a no-ff, no-squash merge commit
Preserve branch names for reference

Dev Notes

Rename App

Versioning Process

This will use a Gemfile as an example but could be done with different versioning systems.

Say your project uses the following:

source 'https://rubygems.org' do
  gem 'nokogiri'
 gem 'rails', '5.0.0'

	<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

	<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
	<head>
	<title>Sliding Frames</title>
	<meta name="warning" content="HC SVNT DRACONES" />
	<link rel="stylesheet" type="text/css" href="http://yui.yahooapis.com/2.6.0/build/reset/reset-min.css" />
	<style type="text/css">
	div#container { overflow: hidden; visibility: hidden; }
	div#navigation { position: absolute; top: 10px; left: 10px; }

	Deploying a Rails App with EC2 + S3 + Ubuntu
	============================================

	Create EC2 Instance
	-------------------

	create new instance ami-bf5eb9d6 [http://alestic.com/](http://alestic.com/)
	create new elastic ip
	attach elastic ip to instance
	point dns to elastic ip

	drefile: an automatic, chronological file organizer
	---------------------------------------------------
	Every few minutes drefile copies all files on your Desktop to a folder
	such as ~/Documents/2009-06-June/26-Friday, prepending a timestamp
	(like 20090626.1310) to the filename.

	Use
	---
	1. Put files on your Desktop, and in a few minutes they will be 'drefiled'
	2. Use the 'Today' alias on your Desktop to go to today's folder

	def conditional_block(do_block, method, *args, &block)
	do_block ? send(method, args, &block) : block.call
	end
