any: magic, ill-behaved type that acts like a combination of never (the proper [bottom type]) and unknown (the proper [top type])
- Anything except never is assignable to any, and any is assignable to anything at all.
- Identities: any & AnyTypeExpression = any, any | AnyTypeExpression = any
- Key TypeScript feature that allows for [gradual typing].
unknown: proper, well-behaved [top type]
- Anything at all is assignable to unknown. unknown is only assignable to itself (unknown) and any.
- Identities: unknown & AnyTypeExpression = AnyTypeExpression, unknown | AnyTypeExpression = unknown

Prefer over any whenever possible. Anywhere in well-typed code you're tempted to use any, you probably want unknown.

QQ可以使用xml的方式发送消息，以下为了方便描述统称为卡片。

通过机器人的API进行发送xml即可，但是如果选择发送xml，那么其他如[image=xxx]、[@xxx]这些命令就不可使用了。整个消息只有XML。

xml主要由msg,item,source这3部分组成

<?xml version='1.0' encoding='utf-8' standalone='yes'?>

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。

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：

	#!/bin/zsh

	test -d ~/ntfs \|\| mkdir ~/ntfs

	disk=$(diskutil list external \| grep -i NTFS \| awk '{print $7}')

	echo "umounting /dev/$disk"
	sudo umount /dev/$disk
	echo "mounting by read and write NTFS privileges..."
	sudo mount -t ntfs -o rw,auto,nobrowse /dev/$disk ~/ntfs

	import xlrd
	from openpyxl.workbook import Workbook as openpyxlWorkbook

	# content is a string containing the file. For example the result of an http.request(url).
	# You can also use a filepath by calling "xlrd.open_workbook(filepath)".

	xlsBook = xlrd.open_workbook(file_contents=content)
	workbook = openpyxlWorkbook()

	for i in xrange(0, xlsBook.nsheets):
