My Objective-C Style guide

This style guide outlines the coding conventions that I try to stick to when writing Objective-C. I'm posting it here mostly as a brain dump and easy reference for the future, and to formalise it a little more.

It's pretty similar to that of the NYTimes. This document is mostly a customised version of that, you should go check theirs out!

If you're looking to see some of the reasons behind some choices, or for something I haven't covered, look at the sites below, Apples documentation is pretty great.

Creating a dynamic site-to-site VPN with OpenSwan on Ubuntu 10.04 on EC2

Wes Winham [email protected]

There are many tutorials floating around the web that almost get you a dynamic VPN in EC2. The goal of this tutorial is to be a one-stop-shop for this specific setup.

	A::B is a system with 4 tokens: `A#`, `#A`, `B#` and `#B`.

	An A::B program is a sequence of tokens. Example:

	B# A# #B #A B#

	To compute a program, we must rewrite neighbor tokens, using the rules:

	A# #A ... becomes ... nothing
	A# #B ... becomes ... #B A#

	# to run we need a few libraries:
	# pip install rich typer

	import os
	import subprocess
	import sys
	import time

	user web;

	# One worker process per CPU core.
	worker_processes 8;

	# Also set
	# /etc/security/limits.conf
	# web soft nofile 65535
	# web hard nofile 65535
	# /etc/default/nginx

	# Use last tag as the base for the version. E.g. tag initial commit as 0.0
	LAST_TAG_VERSION=`git describe --tags \| cut -f1 -d"-"`

	# Optional. Same as above but keeps the commit hash
	#LAST_TAG_VERSION=`git describe --tags`

	# Total number of commits in the repository
	TOTAL_COMMITS=`git rev-list HEAD --count`

	# Write the version numbers to the compiled product
