Setup new Mac with OSX Lion from scratch.

These commands are good as of 2012-03-18.

Install Xcode 4

The download/install takes a while so start it first. When it finishes downloading you will still need to run it to complete installation.

Note: Make sure you install the XCode Command Line Tools after XCode is done installing. To do this go to Xcodes -> Preferences -> Downloads -> Command Line Tools -> Install. If you don't you might not be able to install brew packages (i.e. brew install wget will fail).*

Thanks to Rico for posting the fix (http://ricochen.wordpress.com/2012/02/18/installing-git-on-mac-os-x-lion-through-homebrew-error-fix/)

#FIN_WAIT2 problem at socket.io

I found FIN_WAIT2 was increased at server by using socket.io, version is 0.9.5. So I investigate what protocol was cause this issues. First I was do command sysctl -A | grep net.ipv4 to see my TCP setting:

net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_time = 300
net.ipv4.tcp_keepalive_probes = 9
net.ipv4.tcp_keepalive_intvl = 75

Second, I do this follow:

Practice BFN with nodebnf parse codekit "@codekit-prepend,@codekit-append" expression. see http://incident57.com/codekit/help.php#help-imports-warning

	define (require, exports, module) ->
	console.log 'From hello'
	exports.sayHello = ->
	"Hellow world!"
	return

	#!/bin/bash
	##
	## Simply block DDOS attack
	##

	ARGV1=$1
	if [ $ARGV1 ]; then
	DEFINE=$ARGV1
	else
	DEFINE="100"

	#!/usr/bin/env coffee

	{watch,eventWatch} = require './watch'
	{spawn} = require 'child_process'
	less = require 'less'
	path = require 'path'

	watch 'lib', {extention: '.coffee'}, (err, file) ->
	throw err if err
	coffee = spawn 'coffee', ['-c', '-o', 'lib', "#{file}"]

	#!/usr/bin/env coffee

	common =
	# login email
	login_email : 'your mail'

	var Trello = require("node-trello");


	打开 Preferences -> Terminal 保证：Accept ramte connectio 选中。

	mate ~/.ssh/config

	添加下面：

	登录远程的一台 linux 机器。运行下面的命令：
