# 生成 dhparam.pem 文件, 在命令行执行任一方法:

# 方法1: 很慢
openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048

# 方法2: 较快
# 与方法1无明显区别. 2048位也足够用, 4096更强
openssl dhparam -dsaparam -out /etc/nginx/ssl/dhparam.pem 4096

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

CGRect CGRectIntegralScaledEx(CGRect rect, CGFloat scale)
{
    return CGRectMake(floorf(rect.origin.x * scale) / scale, floorf(rect.origin.y * scale) / scale, ceilf(rect.size.width * scale) / scale, ceilf(rect.size.height * scale) / scale);
}

CGRect CGRectIntegralScaled(CGRect rect)
{
    return CGRectIntegralScaledEx(rect, [[UIScreen mainScreen] scale]);
}

## MAKE SURE YOU BACKUP FIRST - THIS PROCESS WILL WIPE YOUR DEVELOPMENT DATABASE
## e.g. using git source control and database sql export.

## This is not for people who don't want to have to do some manual work 
## getting everything working.
## This also is not officially "supported" but we will hopefully 
## be able to write an upgrade task later on based on feedback.

## Notable files that get overriden:
# CSS: (put yours back afterwards but remove any @import for refinery css)

#!/bin/bash
## call git init
git init
 
## make .gitignore

# Mac OS X Finder and whatnot
