说好的脸面问题在互联网上基本上等于零，因为没人知道一个ID后面是个人还是条狗，所以说大家还在互联网上讲脸面就有点儿可笑了。
所以说很多人总是放不下脸面来，将自己的卖出去，结果就一直苦逼的徘徊在屌丝和草根儿之间，永远成不了互联网上能挣钱的那拨儿人。互联网上能赚钱的都是能咋呼的，其实很多赚大钱的开始能咋呼，后来就低调做人，闷头赚钱去了，那就另一个境界了，但是最初没人知道你的时候，你就只能咋呼，包装自己，出来卖自己。
那么多人在互联网上淘金，又推出了互联网+的概念，可有几个人知道你，所以大胆的出来卖吧！
再说到商品，互联网上什么都可以当初商品来卖，别人不知道的你知道的信息就可以卖个好价钱，什么图片、视频、教程、mp3、账号类的等等所以虚拟的资源都可以拿出来卖，甚至你的一篇经验技巧的文章都有人愿意出钱买，因为这些人需要所以买。
不过在卖之前一定要做好包装，人靠衣裳马靠鞍，没有好的形象和包装的商品让人提不起购买的欲望，尽管你的商品绝对货真价实，互联网上卖东西不再是包子不在褶儿上的方式了，没人有时间去探究深层次的东西，都是买的表面的介绍。
来源： Android udp 广播发送和接收 – the_Gaven – 博客园
最近在和同学开发一款app，作为课程大作业。其中，涉及到udp socket (多播) 的发送和接收、tcp socket 的发送和接收。作为一个Java的门外汉，在简单地看了一些理论地资料之后，实际编程中遇到了不少问题。然后，又在网上大搜这方面的博客，找来找去，其实 大家写的东西基本都一样，因为规则已经订好了。网上的代码不全，又有一些错漏，让我走了很多弯路，无数次推倒代码重写，Debug，终于调出了一个实际可 运行的版本。 希望初学的童鞋看到我的这篇博客能少走一些弯路.

在给出代码之前，先简单介绍一下我的代码在做什么。
代码逻辑:
本机发送udp广播
本机开启线程，监听来自别的机器的udp广播，显示信息。 然后，对udp来源发送tcp连接
接收来自别的机器的tcp连接，并显示信息
(这里的udp广播，我使用udp多播代替了，多播具有广播的所有优点，而且有更少的缺点，实现上也比较简单，这里就不再过多地介绍了)
具体ui操作:
start 按钮用来启动udp 多播，stop按钮停止发送 (实际上，由于start 按钮按下之后只发送一次udp多播，stop按钮只是用于setEnabled操作)下面有两个TextView，内容为send的TextView 显示－－本机发送 tcp socket 的信息； 内容为receive的TextView 显示－－本机接收来自别的机器的udp socket 和 tcp socket 的信息.
几个需要注意的地方：
1. Android Manifest 权限设置、sdk版本信息:
本文所涉及到的这些功能需要获取 Android 的一些权限，下面是我的权限和版本信息
上面 条目 uses-sdk中的信息，需要在build.gradle文件中同步。
2. 注意udp广播，和udp广播监听需要绑定同一个端口
3. 其他的有关IDE抽风的问题，比如我的Android Studio，有时候你修改了代码，重新把程序烧进手机的时候，它竟然会用缓存中代码的老版本来烧程序。。。 还有，有时候project加载太慢，程序崩溃之后，logcat好长时间都不出错误信息，严重影响Debug。
4. 建议使用android sdk版本比较新的手机进行测试。 我测试的时候，用一部4.4和5.1的成功了。混合另外一部4.0.x的则有时候不太灵通。

一直悬在电商头上的税终于是要落下来了，从天猫的严打，到国家征税的到来，不知道多少商家露出无奈，本来就被分摊的利润，平台抽成不算，这国家也要征税了，商家只能被动接受着。
电商从开始就是因减少中间环节降低了成本才让传统企业好像一下子见到了一个高价值的市场，于是纷纷不惜血本的投入到电商大潮中，让本就纷乱的电商市场更加热闹，然后大家都来了，国家不干了，治理开始什么假货、仿货都要治理，最后下来了杀手征税，阿里也坐不住了从平台的严打开始让天下本来难做的生意就更加步履蹒跚了，商家困苦的逃离自建电商又一时半会儿不见效果。
互联网+推动的是多少激情澎湃的创业资金的涌入互联网，又有多少互联网老兵的出逃和跨界影藏在热闹的创业+大潮之下，微商更加是火上浇油得来了一把火，把人们的心都烧乱了，投入到电商的人们在赚着头寸的利润。
不知道电商能走多远，税又怎么个征法儿，老百姓只能等待着那一刻的来临。
来源： Android自定义toast – 飞天小鳄 – 博客园
在开发Android应用时，一般我们都会用toast来弹出提示消息，简单高 效。但是在不同的手机下toast显示的位置和样式可能会不同，而且系统自带的toast样式奇丑（个人觉得…），那么怎样定制一个个性的toast 提示框呢。。。 今天我就分享一下自己写的自定义toast，不足之处还请大家多多指点。（后边有效果图）
1、因为toast的特性，所以我们定义toast为单例模式。
<div class="cnblogs_code_toolbar"><span class="cnblogs_code_copy"><a title="复制代码"><img src="http://www.mikel.cn/wp-content/uploads/2015/05/copycode4.gif" alt="复制代码" /></a></span></div>
<pre>private static ZToast instance; //单例的
private View mToastView;//自定义toast view
private TextView mTextView;
private Boolean mIsShow;//记录状态 是否在显示
private Timer mTimer;//定时器
public synchronized static ZToast getInstance(Context context) {
if (instance == null)
instance = new ZToast(context);
return instance;
}
private ZToast(Context context) {
mIsShow = false;// 记录当前Toast的内容是否已经在显示
//这里初始化toast view
mToastView = LayoutInflater.from(context).inflate(R.layout.common_toast, null);
//用来提示的文字
mTextView = ((TextView) mToastView.findViewById(R.id.toast_text));
//初始化计数器
mTimer = new Timer();
// 设置布局参数
setParams();
}
2、接着设置布局样式：
private LayoutParams mParams;
private void setParams() {
mParams = new WindowManager.LayoutParams();//初始化
mParams.height = WindowManager.LayoutParams.WRAP_CONTENT; //高
mParams.width = WindowManager.LayoutParams.WRAP_CONTENT; //宽
mParams.format = PixelFormat.TRANSLUCENT;
mParams.windowAnimations = R.style.custom_animation_toast;// 设置进入退出动画效果
mParams.type = WindowManager.LayoutParams.TYPE_TOAST;
mParams.flags = WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
| WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
| WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE;
mParams.gravity = Gravity.BOTTOM; //对其方式
mParams.y = 45; //下间距
}
3、自定义toast弹出风格 动画的效果 。 toast_styles.xml
</pre>
<pre><?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="custom.animation.toast" parent="@android:style/Animation.Toast">
<item name="android:windowEnterAnimation">@anim/toast_enter</item>
<item name="android:windowExitAnimation">@anim/toast_exit</item>
</style>
</resources></pre>
<div class="cnblogs_code_toolbar"><span class="cnblogs_code_copy"><a title="复制代码"><img src="http://www.mikel.cn/wp-content/uploads/2015/05/copycode4.gif" alt="复制代码" /></a></span>
toast_enter.xml
</div> <div class="cnblogs_code_toolbar"><?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" > <translate android:duration="1" android:fromXDelta="0" android:fromYDelta="0" android:toXDelta="0" android:toYDelta="85" /> <translate android:duration="350" android:fillAfter="true" android:fromXDelta="0" android:fromYDelta="0" android:interpolator="@interpolator/accelerate_quad" android:toXDelta="0" android:toYDelta="-105" /> <alpha android:duration="100" android:fromAlpha="0" android:toAlpha="1" /> <translate android:duration="80" android:fillAfter="true" android:fromXDelta="0" android:fromYDelta="0" android:startOffset="350" android:toXDelta="0" android:toYDelta="20" /> </set></div> <div class="cnblogs_code_toolbar">
大家会问mWdm是个神马？ 其实它就是WindowManager（public static WindowManager mWdm;），最终还是需要使用它来吧view显示在屏幕上的。我们把它定义在程序的Application类中，并在oncreate（）里初始化 mWdm = (WindowManager) getSystemService(Context.WINDOW_SERVICE); 这样就能保证他的生命周期会比我们的activity长，从而在执行计时器的时候不会报各种各样的异常。(如果有其他更好的办法，望告知。)
然后，在其他类中，使用
ZToast.getInstance(mContext).show("我是自定义的toast",Toast.LENGTH_LONG );
效果如下：
来源： asp.netMVC中的自动绑定模型测试小结 – 的蓝 – 博客园
很久没有自己测试测试一些东西了，今天特意测试了一下MVC中自动绑定模型。本人也是小菜，希望能帮助到小小菜。。。。嘿嘿
1.首先，创建一个MVC4的项目
2.创建一个Controller（控制器），有些小小菜肯定也知道Home是路由里默认的。
3.控制器都有了，默认会有个Index动作方法，我们只需要在拷贝一个接受Post请求的action即可

public ActionResult Index(){ return View();}[HttpPost]//视图中加的是实体类中的属性名对应 //集合模型，视图为动作方法参数名字[索引].属性名public ActionResult Index(List<Student> stu){ return View();} |
为了压缩例子，这里直接就动用集合，这里有个测试类中犹如【小明】般存在的类Student，我们来看它的结构

public class Student{ public int Id { get; set; } public string Name { get; set; } public StudentExt Stu { get; set; }}public class StudentExt{ public string Address { get; set; }} |
好简单吧，我们只是做测试而已，足够了。当我们有了方法和模型了以后，我们需要用一个视图来装载这个模型。添加个视图。
当我们有了视图以后，我们要在里面增加模型的属性，以便在提交表单的时候Action能接收到模型数据。

@{ ViewBag.Title = "Index";}@using (Html.BeginForm("Index")){ @Html.TextBox("stu[0].Id") @*注释，stu代表action的参数名，由于该参数是集合[0]代表第一项，Id代表它的属性，大写的Stu代表stu的属性，Address代表Stu的属性*@<br> @Html.TextBox("stu[0].Name") @Html.TextBox("stu[0].Stu.Address"); <br /> @Html.TextBox("stu[1].Id") @Html.TextBox("stu[1].Name") @Html.TextBox("stu[1].Stu.Address"); <br /> <input type="submit" value="测试简单模型" />} |
我们来运行一下看看效果，当我们点击测试简单模型时，注意点之前注意打个断点以便观察这样是否能拿到模型。
我真点了- -，来看拿到什么了吧！
测试完毕，成功拿到模型数据。
来源： 构建高性能插件式Web框架 – NetUML – 博客园
基于MVC插件模式构建支持数据库集群、数据实时同步、数据发布与订阅的Web框架系统。如下图：
采用插件模式开发的优点是使得系统框架和业务模式有效地进行分离，系统更新也比较简单，只需更新业务插件，不需要动整个框架，开发人员无需关心整个框架结构。
但插件模式调试稍微麻烦一点，比不采用插件模式开发的效率上也要差一点，因为它采用反射进行动态加载插件。
登录插件示例：
namespace LoginPlugin
{
public class Plugin : NetUML.Portal.Framework.AbstractPlugin
{
public Plugin()
{
this.Title = "系统登录";
this.Description = "登录插件";
}
public override string Name
{
get { return "LoginPlugin"; }
set { }
}
public override int StartLevel
{
get { return 2; }
set { }
}
public override void Start(NetUML.Portal.Framework.IBundleContext context)
{
}
public override void Stop(NetUML.Portal.Framework.IBundleContext context)
{
}
public override string SymbolicName
{
set { }
get { return "System.Login"; }
}
public override List<NetUML.Portal.Framework.MenuItem> MenuItems
{
get { return null; }
}
public override NetUML.Portal.Framework.PluginType PluginType
{
get
{
return NetUML.Portal.Framework.PluginType.Login;
}
}
public override string Title
{
get;
set;
}
public override string Description
{
get;
set;
}
}
}
所有插件必须实现 NetUML.Portal.Framework.AbstractPlugin 这个插件抽象类。
当加载插件的时候会执行Start方法，停止插件的时候会执行Stop方法。

程序结构如下图：
NetUML.DataEngine支持多数据库连接，主持数据库读写分离操作，哪些数据表需要读写分离可以进行相应的配置和管理，类似于MVC中的路由概念，咱们可以配置多条路由表，路由表内容包括数
据表名，数据对象关键词以及数据库信息，用户保存数据的时候，系统根据要保存的数据表以及数据对象去寻找路由，再根据路由中的配置信息进行提交到数据库。
进在开发中。。。。。。。。
如果第三方系统接入当前系统当中来，当前系统中的数据发生变化，需要立马通知接入进来的系统，把变化的数据提交给第三方系统，第三方系统接入到数据进行相应的处理。
第三方系统只需要提供给当前系统一个URL地址，当前系统把数据POST到URL地址。
进在开发中。。。。。。。。
系统框架支持上传插件包，不需要到服务器进行更新程序，上传完插件包之后，系统自动把插件包解压出来，进行动态编译加载插件。
系统框架也支持停止和卸载插件。如下图：
文档管理插件支持office等文档在线浏览以及文件转换，把文档转换成HTML文件，支持全文解析和全文搜索功能
进在开发中。。。。。。。。

步骤设计很重要，特别是规则的选择。
我这里分为几个规则
1.按自行选择（在起草时候自行选审批人,比较灵活）
2.按上级（无需指定，当时需要知道用户的上司是谁，可以在职位管理设置，或者在用户表直接设置）
3.按职位（选择职位，直接获得该职位的人员）
4.按部门（按部门，直接获得该部分的人员）
5.按人员（设置步骤时就指定人员）
以上用户必须和部门，职位，上级有所关联，只要做好一个其实全部都同理
表结构分析：Flow_FormStep中有IsAllCheck字段我设计这个的目的是批量审核，比如我选择了部门，那么这个步骤要全部门的人都审核通过才算通过否则其中一人审核即可
先创建一个新的表单，必须有新的表单才能设置步骤
OK，新建好表单的字段之后，就可以设置步骤了
步骤设置很简单，就是一个从表关系，对应了表单的ID。从表可以直接简单看出关系，但设计其实比较有复杂，当选择组织架构，按职位，按指定人。都必须弹出窗口来进行选择，所以还要设计多3个弹出窗口，我这里只设计按人员筛选为例，因为按人员之前在权限管理的角色组管理已经实现
我这里“又”设计成了一个手风琴，具体实现如下
新建步骤和修改步骤=设计步骤

代码分析，控制器中的删除，修改，直接复制代码生成器生成的即可。
ActionResult EditStep，返回Flow_Step模型的同时也返回了Flow_Form的模型。
我修改了Flow_FormModel，让他支持自己的从表关系，必须添加以下2段即可
public List<Flow_FormAttrModel> attrList { get; set; }
public List<Flow_StepModel> stepList { get; set; }
注：本节一点悬念和技术点都没有，就是一个主表和从表的关系，只不过我是换了另一种方式来显示罢了

目录：
一、概述
二、MX设置
三、使用系统的SMTP功能发邮件
四、使用hMailServer收发邮件
五、Web邮件客户端
首先必须清楚SMTP才是提供邮件服务器的核心，收发邮件全靠SMTP。不信你关掉hMailServer的POP3和IMAP，服务器照样可以收 发邮件。POP3和IMAP只是邮件服务器实现的用于提供邮件客户端收取和管理邮件的两种协议，其中POP3协议只能收取服务器上的邮件，而IMAP协议 可供客户端管理服务器上的邮件。目前几乎所有的第三方服务器的SMTP都限制了发送配额等各种限制，并且几乎所有的邮件服务器都会检测发送方的域名和IP 是否匹配。简单说就是别用第三方的进行测试，也别用自建的locahost发邮件测试，到底怎么测试呢？在非服务器环境下的邮件发送测试，有3种方案：
（1）模拟邮件的发送，不真正发送邮件。把邮件发送的内容写到日志文件等。
（2）模拟邮件的接收。使用localhost的SMTP发送邮件。使用SMTP4DEV等拦截接收邮件，配合windows live mail和Windows MBox Viewer等可以读取eml格式的客户端，可以得到正确格式的邮件，收件方不会接收到邮件。
（3）在有域名和服务器可用的前提下，设置域名MX并搭建邮件服务器，通过邮件服务器的SMTP进行邮件的实际发送。可以通过收件方服务器的域名IP检测，但要配置好安全措施防止邮件服务器被利用。
发送邮件可以使用Windows Server 2008+的系统的SMTP功能，但没有提供对POP3和IMAP协议的系统支持，因此无法使用客户端访问邮件服务器。
如果我们希望使用客户端访问邮件服务器，在Windows Server 2008+环境下和开源免费的前提下，目前最好的选择就是hMailServer。如果你打算切换到hMailServer，一定要记得停用系统的SMTP服务。否则hMailServer无法监听SMTP端口，就无法接收到邮件。
MX设置的参考如下，在域名解析中配置：
在服务上检查MX设置：
以Windows Server 2008为例，SMTP功能的安装和服务的设置比较简单，这里省略。

伴随着 iMac 5K Retina 和新的 Mac mini 等硬件的发布，苹果终于都推出了 OS X Yosemite 系统正式版了！相信很多人都已经用上。不过对于一些不想升级，而是打算「全新安装」系统的朋友却遇到一个小问题。
那就是怎样制作 OS X Yosemite 正式版 的U盘启动安装盘？其实方法比较简单，下面我们就给大家带来一个制作 Yosemite U盘启动盘/安装盘的教程吧。这样以后想给 Mac 重装系统、在没有网络的情况下或者帮多台机器安装系统都方便得多……
其实制作 OS X Yosemite 正式版 USB 启动盘的方法有很多，譬如使用命令行的，也有使用第三方工具的。这个教程主要介绍前者，因为这是目前我了解到的最稳妥、简单，而且没有兼容性问题的方法了。
不过大家可别被「命令行」三个字吓到，其实你只需按步骤来，复制粘贴命令即可快速完成，事实上是很简单的。
插入你的 U 盘，然后在「应用程序」->「实用工具」里面找到并打开「磁盘工具」，或者直接用 Spotlight 搜索 “磁盘工具” 打开，如下图。
sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia –volume /Volumes/iPlaySoft –applicationpath /Applications/Install\ OS\ X\ Yosemite.app –nointeraction
回车后，系统会提示你输入管理员密码，接下来就是等待系统开始制作启动盘了。这时，命令执行中你会陆续看到类似以下的信息：
Erasing Disk: 0%… 10%… 20%… 30%…100%…
Copying installer files to disk…
Copy complete.
Making disk bootable…
Copying boot files…
Copy complete.
Done.
当你看到最后有 「Copy complete」和「Done」 字样出现就是表示启动盘已经制作完成了！
当你插入制作完成的 OS X Yosemite U盘启动盘之后，桌面出现「Install OS X Yosemite」的盘符那么就表示启动盘是正常的了。那么怎样通过 USB 启动进行全新的系统安装呢？
其实很简单，先在目标电脑上插上 U 盘，然后重启你的 Mac，然后一直按住「option」(alt) 按键不放，直到屏幕显示多出一个 USB 启动盘的选项，如下图。
这时选择 U 盘的图标回车，即可通过 U 盘来安装 Yosemite 了！这时，你可以直接覆盖安装系统(升级)，也可以在磁盘工具里面格式化抹掉整个硬盘，或者重新分区等实现全新的干净的安装。
最近站长圈里天涯论坛的转股和上市的消息沸沸扬扬，赔钱赔得去上市和转股了，不过天涯能否扭亏为盈，都将是众人瞩目的问题，一个老牌的传统论坛总是有很多人气的，人们都是又爱又恨的关注着事态发展。
很多人分析天涯论坛的亏损原因，又纷纷讨论天涯未来的发展问题，嫣然自己成了天涯的ceo纷纷出谋划策的想办法扭亏为盈，可是都是站着说话不腰疼的。
结果论坛还是转股了，上市不上市不要紧，赚钱才是硬道理，不盈利谁会接这个盘，谁又会敢站出来说能够带领着天涯走过阴霾？能够有这么一个人走出来，估计传统论坛的转型之路也就通了。
有人谣传天涯有搞金融众筹，可总感觉不伦不类的，一个论坛和金融嫁接起来，真的没有先例，没有做还真没准儿能行。毕竟人气是有了，差的就是变现了，可一般泡论坛的都是什么人？能不能投入到金融里面就不得而知了，只能走着看了。
互联网就是这么快，仅仅两年就让天涯步履瞒珊的走上了融资和上市的道路，这是一个多变的世界。
