###Python里对list用sort和sorted排序的一个问题
A=[2,1,3,4,2,2,3]
A.sort(key=lambda x:A.count(x))
print A
[2,1,3,4,2,2,3]
B=sorted(A,key=lambda x:A.count(x))
print B

12345679随便乘以一个80以内的不是3的倍数的正整数所得的数字，每位数字都不重复，并且缺一个数，那一个数就是9减去这个数字除以九的余数。
比如12345679×79=975308641
79除以九余七，缺二。
12345679×65=802469135
65除以九余二，缺七。

从结果来看应该就是 Base64。（区分大小写，字母数量大于数字的数量还有 = ）。应该就是某种方法加密之后，再用Base64编码的。前一段Base64解码出来是 aHR19\x06 \x06是ACK，确认的意思。所以后面可能是用aHR19作为密钥加密的结果。

npm -g install npm
# node有一个模块叫n（这名字可够短的。。。），是专门用来管理node.js的版本的。
# 首先安装n模块：
npm install -g n
#升级node.js到最新稳定版
n stable
# n 后面也可以跟随版本号比如：
n v0.10.26
n这个程序好像只是在linux下才好使,windows下是没用的.var a = [1,2,3,4];
a.push(5); //a 现在是1,2,3,4,5
var a = [1,2,3,4];
var b = [5,6];
var c = a.concat(b); // a,b 数组都不变，c变成了1,2,3,4,5,6
//这里要注意是 c 变成了合并数组 不是 b , 所以这和push是有区别的
var arr1= [1,2,3];
arr1.push.apply(arr1,[4,5]); // 这时 arr1 就是 [1,2,3,4,5]###cooking 更易上手的前端构建工具 首先确保是在 NPM 3+, Node 4+, Python 2.7+ 环境下运行
第一步：安装 cooking 命令行工具
npm i cooking-cli -g
第二步：使用创建项目
cooking create my-project vue
第三步：开始开发
cd my-project && cooking watch
后续：打包、测试等
cooking build # or cooking run test https://zhuanlan.zhihu.com/p/22387692 https://cookingjs.github.io/zh-cn/intro.html
###Windows 系统下设置Nodejs NPM全局路径
查看配置命令
npm config ls -l
Windows下的Nodejs npm路径是appdata，很不爽，想改回来，但是在cmd下执行以下命令也无效
npm config set cache “C:\Program Files\nodejs\node_cache”
npm config set prefix “C:\Program Files\nodejs”
最后在nodejs的安装目录中找到node_modules\npm.npmrc文件
修改如下即可：
prefix = D:\nodejs\node_global
cache = D:\nodejs\node_global(laravel插件) laravel-backup 备份插件http://elickzhao.github.io/2016/10/[laravel%E6%8F%92%E4%BB%B6]%20laravel-backup%20%E5%A4%87%E4%BB%BD%E6%8F%92%E4%BB%B6/ https://packagist.org/packages/spatie/laravel-backup

实现 Hasher 接口,然后替换掉原来的 BcryptHasher 这个类
namespace Illuminate\Contracts\Hashing;
interface Hasher
{
public function make($value, array $options = []);
public function check($value, $hashedValue, array $options = []);
public function needsRehash($hashedValue, array $options = []);
}
//实现这个接口很简单
public function validateCredentials(UserContract $user, array $credentials)
{
$plain = $credentials['password'];
//return md5($plain) == $user->getAuthPassword();
//这里的 hasher 的就行了. 不过还是得改代码
return $this->hasher->check($plain, $user->getAuthPassword());
}定义为抽象的类不能被实例化。任何一个类，如果它里面至少有一个方法是被声明为抽象的，那么这个类就必须被声明为抽象的。被定义为抽象的方法只是声明了其调用方式（参数），不能定义其具体的功能实现。

原有的标签顺序狠不好,JS文件在前显示结果在后.所以要改一下,把结果放在前面.
//jsfiddle.net/elick/s03Lk51x/embedded/result,js,html,css
其实很简单,embedded/后面这个结构就是标签顺序.http://code.hcharts.cn/blog-demo/OYZT3i/1
//其实这个很直白了 因为一般bool值 表示 ture 为 1 false 为 0
!0 == true
!!0 == false
//但是 !0 === true 这是错的 恒等于 是不会转义类型的 所以 0 还是 int 型 所以不能与 bool 型相等
//这些都是同理了
!1 == false
!!1 == true
//这是设置 a 为 undefined , 如果用字符串代替会存在浏览器兼容问题
//也可以在 return 时使用,表示返回空,只是执行操作.
//具体看下面参考文档
var a = viod 0;###php 隐藏下载地址

$this->hasOne('App\Models\UserAccount',$foreign_key,$local_key);

其默认值为调用belongsTo的方法名，这里是user。

Laravel框架默认存储每次请求(每次命令行执行也相当于一次请求)的所有数据库查询语句！！！
在普通的http中数据库请求语句并不多，所有不会导致问题，但是需要大量数据库查询的命令行工具就显然不能这么干，解决方法是禁用query日志：
DB::connection()->disableQueryLog(); //禁用query log###loading加載完成後消失 https://jsfiddle.net/6gpjjv40/ https://github.com/anchengjian/components/tree/master/loading-bar $(document).on("readystatechange",function(){
