WR703N OpenWrt 配置流程

下载安装

下载http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin

2.1 原厂固件中，直接web页面升级 2.2 已刷openwrt的话，telent/ssh登录，下载bin文件到/tmp，运行'sysupgrade -i /tmp/openwrt-ar71xx-ubnt-rspro-squashfs-sysupgrade.bin'

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

	在bcore的开发过程中，涉及到上传文件有两个地方，一个是相册，一个是文章图文混排。这里作为一个备忘。罗列一些关键点：

	文件上传的内容体在tornado.web.RequestHandler.request.files属性中，并且是以数组形式存放的。
	使用临时文件存储时，在write完成后要记着把seek重置到文件头。要不然文件无法被读取。
	再使用Image模块的thumbnail方法进行缩放时,resample=1作为重载渲染参数能够有效的使图片平滑，消除锯齿。
