android 自带的 base64 编码

首先导入包
import android.util.Base64;
String 变量 =android.util.Base64.encodeToString(字符串.getBytes(),Base64.DEFAULT);
也可简写为
String 变量 =Base64.encodeToString(字符串.getBytes(),Base64.DEFAULT);
至于解码
byte b[]=android.util.Base64.decode( 字符串,Base64.DEFAULT);
String 变量 =new String(b);

#!/usr/bin/env ruby
require "optparse"

#store options in hash
options = {}
opt_parse = OptionParser.new do |opts|
  opts.banner = 'kp: kill multi process with keywords.'
  opts.separator  ""
  opts.separator  "Options"

最近在看Sinatra 1.3.5的源码。在Sinatra::Helpers模块中看到一个名为uri的方法，用来将一个相对路径转换为绝对路径。在该函数的代码中看到分别针对request.script_name和request.path_info进行了处理。但是并不清楚这两个参数的区别，于是做了一些reseach。

二者在RFC3875中有如下定义：

4.1.13. SCRIPT_NAME

The SCRIPT_NAME variable MUST be set to a URI path (not URL-encoded) which could identify the CGI script (rather than the script's output). The syntax is the same as for PATH_INFO (section 4.1.5) >

#encoding
task :default => [:base]

#eg: rake lookup[400]
desc "lookup http status explian info with status_code"
task :lookup, [:status_code] => :base do |t, args|
  args.with_defaults(:status_code => "200")
  status_code = args[:status_code].to_s
  Rake::Task["usage"].invoke and exit unless status_code.length != 3 or (1..5).to_a.include?(status_code[0].to_i)

备份：

备份整个数据库
exp 用户名/密码@连接的远程计算机 IP/ 要备份的远程数据库名称 file= 文件路径 
exp hom/[email protected]/qa file=d:\aa1.dmp  

备份指定数据库表
exp Intfocus/[email protected]/orcl file=d:\DOG_TOTAL_BI.DMP tables=(dog_totle_bi)

导入指定数据库表（若表结构已经存在只导入数据）

source/_includes/custom/head.html中添加js代码:

<script>
  function addBlankTargetForLinks () {
    $('a[href^="http"]').each(function(){
        $(this).attr('target', '_blank');
    });
  }

  $(document).bind('DOMNodeInserted', function(event) {
