近来由于 Mac 出了点小问题一直没有解决，加上用了已经有好长一段时间，一直想清理一下(精神洁癖作祟)，所幸重装了事。没有使用 TimeMachine，所以需要先行将一些觉得尚有价值的文件拷贝下来。

写下这篇文章，也是为了以后再次遇到问题能够有章可循，不至于胡乱一通重装。本文也会持续更新，欢迎大家分享更好的使用技巧与经验。

重装 macOS

在线恢复系统实在太慢，进行在 Windows 下制作 Mac U盘启动盘重装系统. 额外所需的物理设备为 U 盘一个，8G 及以上为宜。

1. 准备软件与镜像

# Usage:
#   [sudo] gem install mechanize
#   ruby tumblr-photo-ripper.rb

require 'rubygems'
require 'mechanize'

# Your Tumblr subdomain, e.g. "jamiew" for "jamiew.tumblr.com"
site = "doctorwho"

Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb

import Image, ImageDraw, ImageFont
import struct


font_width = 16
font = ImageFont.truetype("/usr/share/fonts/truetype/wqy/wqy-zenhei.ttc", font_width)
