## Rails development best practices
# An #RMM alternative, open and collaborative set of development practices we can adhere to.

* Distributed Version Control over relying on the File System
* Business Logic in the Models over being spread throughout the MVC layers
* RESTful Architecture over overloaded controllers
* KISS - Short methods with descriptive names
* Tests/Specs covering each layer of MVC and the whole stack
* Document the setup procedure (freeze dependancies where possible)
* Allow developers to listen to favorite music while coding, Put them in zero interruption zone

# Monitor HTTP requests being made from your machine with a one-liner..
# Replace "en1" below with your network interface's name (usually en0 or en1)
sudo tcpdump -i en1 -n -s 0 -w - | grep -a -o -E "Host\: .*|GET \/.*"

# OR.. to be able to use as "httpdump" from anywhere, drop this into ~/.bash_profile:
# (again replace "en1" with correct network interface name)
alias httpdump="sudo tcpdump -i en1 -n -s 0 -w - | grep -a -o -E "Host\: .*|GET \/.*""

# All the above tested only on OS X.

# urlmonitor - print out the URLs requested system wide on the main network interface

# Accept a network interface name as an optional argument
  iface = ARGV.first

# No interface specified? Try to guess which one is king..
  unless iface
    `ifconfig -l`.split.each do |iface|
      next if iface =~ /^lo/
      break if `ifconfig #{iface}` =~ /inet (0|1|2)/

You should never do this in a source file included with your library,
app, or tests:

    require 'rubygems'

The system I use to manage my $LOAD_PATH is not your library/app/tests

class UsersController < ApplicationController

  # GET /users
  # GET /users.xml
  def index
    @users = User.all
    respond_with(@users)
  end

Poor Man's Deploy

• Start a Sinatra server on port 4000
• GET / to that server triggers a git pull and mod_rails restart
• Hit port 4000 locally after pushing

Why?
