vagrant-proxyconf with host proxy environment variables

To use the proxy environment variables of the host OS, insert the snippet into your Vagrantfile. Instead of having to manually define the proxy settings, it will use the settings from the host shell where you run Vagrant.

You need to install the vagrant-proxyconf plugin for this to work:

vagrant plugin install vagrant-proxyconf

docker用来隔离应用还是很方便的，一来本身的操作较为简单，二来资源占用也比虚拟机要小得多，三来也较为安全，因为像数据库这样的应用不会再全局暴露端口，同时应用间的通信通过加密和端口转发，更加安全。

Gitlab是目前比较流行的开源类Github代码管理平台。Gitlab使用Rails开发，使用PostgreSQL或MySQL数据库，Redis做缓存。一般自己搭建私有代码仓库，Gitlab通常是首选。这里简单介绍一下dockerized Gitlab。

Gitlab的docker镜像早已有人做好了，并且维护相当不错。大家可以前往其GitHub仓库了解该镜像的情况。官方repo的readme中已经有详细的安装配置方案，这里我简单的梳理一下部署流程。

安装Docker

这里以Ubuntu 14.04发行版为例，在bash中输入一下命令安装最新的docker：

I wrote this four years ago, so instead use this command:

$ docker rmi $(docker images -q -f dangling=true)

OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.

	from django.contrib.auth.models import User

	from django.contrib.admin import AdminSite

	brew tap homebrew/versoins
	brew install FORMULA # here is maven30\maven31\maven2 etc...
	brew unlink maven2 # suppose that maven2 (version 2.2.1) is installed previously
	brew link maven30 # now maven30 (version 3.0.x) will substitute maven2
	# to revert this process, no need to reinstall maven2. just
	brew unlink maven30
	brew link maven2
