Debian和OpenMediaVault在命令行下设置更新源

很多时候我们比较纠结的问题是，“该把哪个Debian镜像发布站点加入source.list文件？”。

Ubuntu的图形界面中有一个测试工具，命令行下面的Debian也有一个现成的程序：netselect。

安装netselect

1	$ sudo apt-get install netselect

不带参数运行它时会显示它的帮助信息。运行它时加上以空格分隔的镜像主机列表，它会返回一个分值和列表中的一个主机名。这个分值通过评估ping time和hopsnumber（一个网络请求报文到达目标主机所经过的转发主机的个数）得出，它与镜像站点预计下载速度成反比（数值越小越好）。返回的主机名是主机列表中得分最低的那个（查看列表中所以主机的得分情况可使用-vv选项）。看出下的例子：

$ netselect http://mirrors.aliyun.com/debian/ http://mirrors.163.com/debian/

5 http://mirrors.163.com/debian/

它表示，在netselect后列出的所有主机中，http://mirrors.163.com/debian/是下载速度最快的主机，其得分为5。

注意，最近163的服务器不知道发生了何种故障，导致各种更新失败，尽管测试的结果是163更快，但是我们建议还是使用阿里云的服务器。

把netselect找到的连接速度最快的镜像站点手工加入/etc/apt/sources.list文件.

最新版本的netselect软件包包含了netselect-apt脚本，它使上述操作自动完成。只需将发布目录树做为参数（默认为stable）输入，sources.list文件就会生成速度最快的main和non-US镜像站点列表，并保存在当前目录下。

$ sudo apt-get install netselect-apt

$ netselect-apt stable

$ sudo mv /etc/apt/sources.list /etc/apt/sources.list.old

$ sudo mv sources.list /etc/apt/sources.list

$ sudo apt-get update

对于OpenMediaVault用户还是手工修改配置文件好了，主要是上面的工具生成的比较简略

JS常用方法封装

做项目是遇到一个封装的不错的Util类，写一下，长期备用：

CMD标准

define(function(require, exports, module) {
    "use strict";

function Util() {}

(function() {
        Util.isWindow = function(obj) {
            return obj !== null && obj === obj.window;
        };

Util.isFunction = function(obj) {
            return typeof obj === 'function';
        };

Util.isObject = function(obj) {
            return typeof obj === 'object';
        };

Util.isArray = function(obj) {
            return obj instanceof Array;
        };

Util.isPlainObject = function(obj) {
            return Util.isObject(obj) && !Util.isWindow(obj);
        };

Util.isString = function(obj) {
            return typeof obj === 'string';
        };

// 将其他的object统统搞到一个object中去
        // 这个函数不如直接写两个参数看着舒服 target objects，就不用各种slice shift了
        Util.extend = function(target) {
            var deep;
            var args = [].slice.call(arguments, 1);

if (typeof target === 'boolean') {
                deep = target;
                target = args.shift();
            }

args.forEach(function(arg) {
               extend(target, arg, deep);
            });

return target;

// 这个函数就是把source里面的一层一层往下展开给target，object 和 array会一直展开
            function extend(target, source, deep) {
                for (var key in source) {
                    if (deep && (Util.isPlainObject(source[key]) || Array.isArray(source[key]))) {
                        if (Util.isPlainObject(source[key]) && !Util.isPlainObject(source[key])) {
                            target[key] = {};
                        }

if (Array.isArray(source[key]) && !Array.isArray(target[key])) {
                            target[key] = [];
                        }
                        extend(target[key], source[key], deep);
                    } else {
                        target[key] = source[key];
                    }
                }
            }
        };

Util.ajaxGet = function(url, data, callback) {
            // 简单学习一下XMLHttpRequest，一个JS对象，提供了封装的获得url上资源数据的方法，支持xml http ftp file

Ubuntu 12.04 + Apache2.2.22搭建SPDY服务器

SPDY是Google开发的基于传输控制协议(TCP)的应用层协议，该协议规定在一个SPDY连接内可以有无限个并行请求，服务器可以主动向客户端发起通信向客户端推送数据，通过请求优化、预加载、压缩HTTP 来达到加速的目的。

对用记而言，SPDY是基于SSL加密，它可以让网络访问更安全，用户隐私更加得到保护。对站长而言，SPDY在降低连接数目的同时，还使服务器上每个客户端占用的资源减少，从释放出更多内存和CPU ，让网站的浏览速度提升不少。

SPDY协议已经被Chrome、Firefox、Opera、IE 11以上支持，用户在访问使用SPDY协议加载的网站几乎感觉不到与普通的Https页面访问有何不同，而SPDY带来的页面加载速度提升和服务器性能优化确是有十分重要意义的。

具体的操作步骤如下：

启用Apache2的HTTPS支持

参考 UBUNTU 12.04 下 APACHE 2.2.22 开启 HTTPS

下载Apache2的mod_spdy模块

官网：https://developers.google.com/speed/spdy/mod_spdy/
由于众所周知的原因，本站提供下载（2015-11-6版本）
mod_spdy 64-bit .deb (Debian/Ubuntu)
mod_spdy 32-bit .deb (Debian/Ubuntu)

安装mod_spdy模块（本站是64位系统）

1 2	$sudo dpkg -i mod-spdy-*.deb $sudo apt-get -f install

重启Apache2

1	$sudo service apache2 restart

验证

目前验证貌似没有起作用啊！目前最新的chrome已经没办法进行验证了，主要是由于HTTP/2已经发布，Google放弃了spdy,转而支持HTTP/2，还是静待新版本的HTTP/2吧。

卸载

1 2	$sudo dpkg -r mod-spdy-beta $sudo dpkg -P mod-spdy-beta

Ubuntu 12.04安装PHP5的php-curl扩展

在使用WP-Statistics统计插件的时候，提示GeoIP需要 php-curl扩展。搜索了一下，安装方式如下：

1	$ sudo apt-get install php5-curl

安装完成后，需要重启Apache2

1	$ sudo service apache2 restart

IScroll的使用-方向键绑定&自定义滚动条样式

之前在webkit上开发一个滚动控件，需要完成的是一段文字，上下键可以滚动，且自定义滚动条。第一想法就是浏览器原生overflow：scroll，且webkit支持自定义滚动条样式：

webkit自定义滚动条样式：

/*定义滚动条高宽及背景高宽分别对应横竖滚动条的尺寸*/

::-webkit-scrollbar

{

width: 0.05rem;

height:1rem;

background-color: transparent;

}

/*定义滚动条轨道内阴影+圆角*/

::-webkit-scrollbar-track

{

background-color: transparent;

}

/*定义滑块内阴影+圆角*/

::-webkit-scrollbar-thumb

{

border-radius: 0.1rem;

/*-webkit-box-shadow: inset 0 0 6px rgba(0,0,0,.3);*/

background-color: rgba(255,255,255,0.6);

}

后来换了个引擎，发现其他引擎不支持自定义滚动条，那就满足不了UED的要求了。来同事推荐使用IScroll，用了一下，确实比较方便，与平台无关，可操作的属性还有性能都很理想，记录一下：

首先看官方文档 https://iiunknown.gitbooks.io/iscroll-5-api-cn/content/versions.html

github地址：https://github.com/cubiq/iscroll

demo：http://cubiq.org/dropbox/iscroll4/examples/simple/

直接拿demo中的iscroll.js套到自己的工程上，一个段落就是一个li，new 一下就完事了，滚动拖动也很happy。然后发现，我按上下方向键没有响应。

IScroll按键事件绑定：

查源码看iscroll的事件处理，都在handleEvent函数里面

handleEvent: function (e) {

var that = this;

switch(e.type) {

case START_EV:

if (!hasTouch && e.button !== 0) return;

that._start(e);

break;

case MOVE_EV: that._move(e); break;

case END_EV:

case CANCEL_EV: that._end(e); break;

case RESIZE_EV: that._resize(); break;

case WHEEL_EV: that._wheel(e); break;

case 'mouseout': that._mouseout(e); break;

case TRNEND_EV: that._transitionEnd(e); break;

}

根本就没有keyEvent，看来偷懒是不行的，官方文档看一下，原来iscroll有5个版本，各自平台都是不一样的，demo中这个估计是移动平台用的iscroll-lite版本，移动平台根本不鸟方向键的。

去github上down下来源码，找了找，build目录下，5个版本都有。用最原始的common版本，这个版本的handleEvent就丰富多了：

handleEvent: function (e) {
   switch ( e.type ) {
      case 'touchstart':
      case 'pointerdown':
      case 'MSPointerDown':
      case 'mousedown':
         this._start(e);
         break;
      case 'touchmove':
      case 'pointermove':
      case 'MSPointerMove':
      case 'mousemove':
         this._move(e);
         break;
      case 'touchend':
      case 'pointerup':
      case 'MSPointerUp':
      case 'mouseup':
      case 'touchcancel':
      case 'pointercancel':
      case 'MSPointerCancel':
      case 'mousecancel':
         this._end(e);
         break;
      case 'orientationchange':
      case 'resize':
         this._resize();
         break;
      case 'transitionend':
      case 'webkitTransitionEnd':
      case 'oTransitionEnd':
      case 'MSTransitionEnd':
         this._transitionEnd(e);
         break;
      case 'wheel':
      case 'DOMMouseScroll':
      case 'mousewheel':
         this._wheel(e);
         break;
      case 'keydown':
         this._key(e);
         break;
      case 'click':
         if ( !e._constructed ) {
            e.preventDefault();
            e.stopPropagation();
         }
         break;
   }
}

handleEvent: function (e) {

switch ( e.type ) {

case 'touchstart':

case 'pointerdown':

case 'MSPointerDown':

case 'mousedown':

this._start(e);

break;

case 'touchmove':

case 'pointermove':

case 'MSPointerMove':

case 'mousemove':

this._move(e);

break;

case 'touchend':

case 'pointerup':

case 'MSPointerUp':

case 'mouseup':

case 'touchcancel':

case 'pointercancel':

case 'MSPointerCancel':

case 'mousecancel':

this._end(e);

break;

case 'orientationchange':

case 'resize':

this._resize();

break;

case 'transitionend':

case 'webkitTransitionEnd':

case 'oTransitionEnd':

case 'MSTransitionEnd':

this._transitionEnd(e);

break;

case 'wheel':

case 'DOMMouseScroll':

case 'mousewheel':

this._wheel(e);

break;

case 'keydown':

this._key(e);

break;

case 'click':

if ( !e._constructed ) {

e.preventDefault();

e.stopPropagation();

}

break;

}

然后套用上去，可以支持方向键了。中间遇到两个小问题，第一个是按键一直没反应，检查下是z-index太小，keyEvent被上层元素拿走了；第二个是只有在#warpper拿到focus的时候才响应按键，但我用的引擎不支持focus，这个也不难，页面强行绑定handleEvent：

document.addEventListener("keydown", function(evt) {

if (evt.keyCode === keyCodes.ENTER) {

} else {

myScroll && myScroll.handleEvent(evt);

}

}, false);

然后整个页面随便按什么键，都可以响应了。接下来就是滚动条样式的问题了，这个也简单，跟着官方文档&样例走就行

http://lab.cubiq.org/iscroll5/demos/styled-scrollbars/

关键步骤有三个：

1.option

myScroll = new IScroll(document.getElementById('wrapper'), {

keyBindings: true, // 绑定按键事件

scrollbars: 'custom', // 自定义样式

resizeScrollbars: false // 是否自动缩放滚动条

});

设置了scrollbars: 'custom'，在页面的Elements就可以找到

里面还包含了

第一个是滚动区域，第二个是滚动条。拿到Element就好办了，css给定样式：

.iScrollVerticalScrollbar {

position: absolute;

z-index: 9999;

width: 0.1rem;

bottom: 2px;

top: 2px;

right: 0;

overflow: hidden;

}

.iScrollIndicator {

position: absolute;

width: 0.08rem; height: 0.3rem;

background: rgba(255,255,255,0.6);

border-radius: 0.1rem;

}

大功告成！

当然，IScroll不止这点功能，官方文档后面还有无限滚动等高级用法，以后用到再添加。

WordPress使用WP-PostViews实现网站上显示文章的浏览量

WordPress的使用很方便，但是文章的点击浏览量默认是没有的，本文介绍用WP-PostViews实现网站上显示文章的浏览量的功能。效果如下图所示：

安装WP-PostViews插件

在插件界面中安装WP-PostViews插件，并且启用插件。

修改主题文件(Twenty Fourteen)

修改content.php，找到如下代码：

<?php

if ( 'post' == get_post_type() )

twentyfourteen_posted_on();

if ( ! post_password_required() && ( comments_open() || get_comments_number() ) ) :

<?php

endif;

edit_post_link( __( 'Edit', 'twentyfourteen' ), '<span class="edit-link">', '</span>' );

</div>

在后面添加：

<?php

/*View Counter for wp-postviews*/

if(function_exists('the_views')) { the_views(); }

修改后的结果如下：

<?php

if ( 'post' == get_post_type() )

twentyfourteen_posted_on();

if ( ! post_password_required() && ( comments_open() || get_comments_number() ) ) :

<?php

endif;

edit_post_link( __( 'Edit', 'twentyfourteen' ), '<span class="edit-link">', '</span>' );

<?php

/*View Counter for wp-postviews*/

if(function_exists('the_views')) { the_views(); }

</div>

修改主题文件(Twenty Fifteen)

修改content.php，找到如下代码：

<?php twentyfifteen_entry_meta(); ?>

<?php edit_post_link( __( 'Edit', 'twentyfifteen' ), '<span class="edit-link">', '</span>' ); ?>

</footer>

在后面添加：

<?php

/*View Counter for wp-postviews*/

if(function_exists('the_views')) { the_views(); }

修改后的结果如下：

<?php twentyfifteen_entry_meta(); ?>

<?php edit_post_link( __( 'Edit', 'twentyfifteen' ), '<span class="edit-link">', '</span>' ); ?>

<?php

/*View Counter for wp-postviews*/

if(function_exists('the_views')) { the_views(); }

</footer>

Windows下VirtualBox直接使用物理硬盘作虚拟机磁盘

目前VirtualBox只能用命令行来建立磁盘才可以使用物理硬盘。

我们假定VirtualBox安装在“D:\Program Files\Oracle\VirtualBox”这个目录下面，要在“D:\Users\VirtualBox VMs\Ubuntu\”目录下面生成文件，则执行如下命令：

1	"D:\Program Files\Oracle\VirtualBox\VBoxManage.exe" internalcommands createrawvmdk -filename "D:\Users\VirtualBox VMs\Ubuntu\Ubuntu.vmdk" -rawdisk \\.\PhysicalDrive1

\\.\PhysicalDrive1 表示机器上的第二块硬盘，\\.\PhysicalDrive0是第一块，\\.\PhysicalDrive2是第三块，以此类推。

在Windows 的磁盘管理中能看到硬盘的分区路径。如下图所示：

然后新建虚拟机，选择"使用已有的虚拟硬盘文件"，找到刚刚创建的 Ubuntu.vmdk 即可。

对于Windows 8.1/10系统，以上的命令需要以管理员启动命令行的方式下启动并执行，否则会报告找不到磁盘。另外启动Virtual Box的时候，同样需要以管理员的身份运行，否则会出现VERR_ACCESS_DENIED错误，如下图所示：

VERR_ACCESS_DENIED

使用grunt压缩代码&配置多个任务

grunt是node环境下一个压缩、合并 js、css代码的工具，还可以做一下代码美化等。体验了一下压缩合并，还是不错的，大概流程如下：

在工程下建一个grunt目录，写两个文件 package.json-工程依赖Gruntfile.js-压缩任务

package.jsn:

{

"name": "xxx",

"version": "v0.1.0",

"devDependencies": {

"grunt": "^0.4.5",

"grunt-contrib-concat": "~0.5.1",

"grunt-contrib-cssmin": "~0.12.3",

"grunt-contrib-jshint": "~0.10.0",

"grunt-contrib-nodeunit": "~0.4.1",

"grunt-contrib-uglify": "~0.5.0",

"grunt-htmlhint": "~0.9.2"

}

Gruntfile.js:

module.exports = function(grunt) {
    // 配置参数
    grunt.initConfig({
        pkg:grunt.file.readJSON('package.json'),
        // 代码合并
        concat:{
            options:{
                separator: ";",
                stripBanners: true
            },
            dist:{
                src:[
                    "../focusManager/base.js",
                    "../focusManager/tween.js",
                    "../focusManager/widget.js",
                    "../focusManager/yunos.js"
                ],
                dest: "dest/focusManager.js"
            }
        },
        // 代码压缩
        uglify:{
            options:{

},
            dist:{
                files:{
                    "dest/focusManager-min.js" : "dest/focusManager.js"
                }
            }
        },
        // css压缩
        cssmin: {
            options: {
                keepSpecialComments: 0
            },
            compress:{
                files:{
                    "dest/default.css": [
                        "../focusManager/base.css",
                        "../focusManager/reset.css"
                    ]
                }
            }
        }
    });

// 载入concat、uglify、cssmin插件，进行压缩
    grunt.loadNpmTasks('grunt-contrib-concat');
    grunt.loadNpmTasks('grunt-contrib-uglify');
    grunt.loadNpmTasks('grunt-contrib-cssmin');

// 注册任务
    grunt.registerTask('default', ['concat', 'uglify', 'cssmin']);
};

module.exports = function(grunt) {

// 配置参数

grunt.initConfig({

pkg:grunt.file.readJSON('package.json'),

// 代码合并

concat:{

options:{

separator: ";",

stripBanners: true

dist:{

src:[

"../focusManager/base.js",

"../focusManager/tween.js",

"../focusManager/widget.js",

"../focusManager/yunos.js"

dest: "dest/focusManager.js"

}

// 代码压缩

uglify:{

options:{

dist:{

files:{

"dest/focusManager-min.js" : "dest/focusManager.js"

}

// css压缩

cssmin: {

options: {

keepSpecialComments: 0

compress:{

files:{

"dest/default.css": [

"../focusManager/base.css",

"../focusManager/reset.css"

]

}

});

// 载入concat、uglify、cssmin插件，进行压缩

grunt.loadNpmTasks('grunt-contrib-concat');

grunt.loadNpmTasks('grunt-contrib-uglify');

grunt.loadNpmTasks('grunt-contrib-cssmin');

// 注册任务

grunt.registerTask('default', ['concat', 'uglify', 'cssmin']);

};

这个Gruntfile很容易理解，想要压缩的文件以及目标文件写好就行，还有另一种自动化的写法，后面再说。

之后运行命令，grunt

出现了一个错误，网上解释

Note that installing grunt-cli does not install the grunt task runner! The job of the grunt CLI is simple: run the version of grunt which has been installed next to a Gruntfile. This allows multiple versions of grunt to be installed on the same machine simultaneously.

So in your project folder, you will need to install (preferably) the latest grunt version:

也就是说，之前装的grunt-cli只是grunt的运行环境，在工程目录下，还需要装一下grunt，运行一下命令：

$npm install grunt --save-dev

Option --save-dev will add grunt as a dev-dependency to your package.json. This makes it easy to reinstall dependencies.

之后再次运行grunt命令，又出现错误：

好吧，没有装这三个插件？原来是grunt一样，也要在工程下装，分别运行 npm install装一下，运行，成功：

工程复杂之后，肯定不会一个一个手动填文件，grunt也可以通过逻辑自动压缩js css文件，Gruntfile.js写法：

module.exports = function(grunt) {
    // 任务配置
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),

// 压缩JS
        uglify: {

};

逻辑也很简单，就是把src里面的文件，压缩，生成文件会经过rename函数处理。

这里面需要注意的地方有

1	src: ['.js', '/.js'],

如果只写一个*.js，是不会递归cwd目录下的所有文件的，要递归几级写到数组中就可以了，如果不想添加什么文件，加！符号-‘！*.min.js’。

当然，这次也没有一帆风顺，运行的时候遇到错误：

报错在最后一句，

1	grunt.registerTask('default', ['uglify', 'cssmin']);

查了半天也没找到这里有什么错误，网上搜了一下，大多数是中括号里的uglify没有引号，跟我的情况也不一样。后来仔细检查了一下代码，发现了两处拼写错误，改了后就运行通过了，也就是说，其他错误都会报到最后一句。

做了一个小小的试验，写一个空模块

(function(){

// for test

})();

压缩后是这样的：

对，什么都没了。

最近有新的需求，压缩不同版本的文件，就需要开多个contact uglify任务，琢磨了一会，搞出来了，同时对grunt有了进一步的认识。

r简单看一下配置文件

contact

首先配置了option，option中配置了不同文件中间增加;分隔符。

这个是contact所有任务的全局配置

后面又写了三个合并任务，分别配置下src和dest就可以了。

合并顺序就是 src中配置的顺序，*.js则按照字母排序。

uglify

uglify中配置了三个压缩任务，

压缩contact的文件

压缩所有文件并生成.min.js

最后运行

1	grunt.registerTask('default', ['concat', 'uglify']);

会自动加载contact和uglify中的所有任务。

ES6新特性

ECMAScript出现了许多有趣的新特性，梳理一下：

1.支持constant声明

ES5中，想实现constant变量必须通过修改var的property实现

Object.defineProperty(this, "PI", {

value: 3.1415926,

configurable: false,

writable: false

});

2.支持块作用域声明let，

JS只有函数作用域，没有块作用域，var声明有变量提升的效果，即如果var声明了一个未声明过的变量，会自动将此声明提升到顶端，所以想实现块作用域在ES5中是通过闭包的形式。

1	(function(param) {})(i);

同时ES6也支持了块级作用域的函数

3.一种function的新写法

function中支持this的使用

nums.forEach(function(v) {

return foo(v);

});

nums.forEach(v => {

foo(v)

});

4.undefined参数默认配置

ES6:

function(x, y = 7, z = 10) {

return x + y + z;

}

等效于ES5：

function(x, y, z) {

if (y === undefined) {

y = 7;

}

if (z === undefined) {

z = 10;

}

return x + y + z;

}

5.支持剩余参数写法

即...p写法会被解释为

1	p.prototype.slice

ES6：

function f (x, y, ...a) {

return (x + y) * a.length

}

f(1, 2, "hello", true, 7) === 9

ES5：

function f (x, y) {

var a = Array.prototype.slice.call(arguments, 2);

return (x + y) * a.length;

};

f(1, 2, "hello", true, 7) === 9;

6.可以直接在字符串中加入${表达式}

即console.log("Error: ${e.toString()}");

7.引用

//lib/math.js

export function sum(x, y) {return x + y};

export var pi = 3.1415926;

//app.js

import * as math from "lib/math"

console.log(math.sum(math.pi, math.pi););

8.支持class 继承，setter、getter

class Shape {

constructor (id, x, y) {

this.id = id;

this.move(x, y);

}

move (x, y) {

this.x = x;

this.y = y;

}

class Rectangle extends Shape {

constructor (id, x, y, width, height) {

super(id, x, y);

this.width = width;

this.height = height;

}

set width(width) {this.width = width}

get width() {return this.width}

}

class Circle extends Shape {

constructor (id, x, y, radius) {

super(id, x, y);

this.radius = radius;

}

9.支持Promise Generators（待学习）

10.bufferArray

class Example {

constructor (buffer = new ArrayBuffer(24)) {

this.buffer = buffer

}

set buffer (buffer) {

this._buffer = buffer

this._id = new Uint32Array (this._buffer, 0, 1)

this._username = new Uint8Array (this._buffer, 4, 16)

this._amountDue = new Float32Array(this._buffer, 20, 1)

}

get buffer () { return this._buffer }

set id (v) { this._id[0] = v }

get id () { return this._id[0] }

set username (v) { this._username[0] = v }

get username () { return this._username[0] }

set amountDue (v) { this._amountDue[0] = v }

get amountDue () { return this._amountDue[0] }

}

let example = new Example()

example.id = 7

example.username = "John Doe"

example.amountDue = 42.0
