已经好久没有写博客了�Q�不是因为没有学东西�Q�而是因�ؓ(f��)学的东西不够�pȝ��Q�不够具体，没有整理��h��Q�外加�h懒）�Q�所以不��x��费笔墨。所以一直潜水。。但��M��(x��)有感想的�Q�在学习(f��n)的过�E�中�Q�时�怼�(x��)遇到一些��o(h��)人惊喜的东西�Q��o(h��)人拍案叫�l�的东西�Q�但学会(x��)之后觉得��单或者不��g��提，于是没有当机立断写出一些洞见。事后用的时候倒觉得理所当然了。其实这是要不得的，学习(f��n)的过�E�我认�ؓ(f��)不应该是�U��a(b��)的吸�Ӟ��而是要有选择的过滤，留其�_�֍��Q�去其糟�_?/strong>�Q�如果能加入自己的�ȝ��更好了�Q�只可惜我在很多时候忘��C��q�事儿，或者在很多时候没有空下来专门做一�ơ如此认真的�ȝ��。但在技术的层面上，一般的说法是，��M��一�U�技术都是基于某�U�设计思想�Q�而至于用什么来具体实现�q�不是最重要的。其实思想和设计不能用��单的一对一和一对多关系来说明。经�怼�(x��)有�h说一�U�思想可以衍生多种技术，其实他只说对了一半，因�ؓ(f��)一�U�技术�ƈ不只是一�U�思想的实玎ͼ�而是多种思想的交融�?/p>

拿��Y件设计来��_(d��)��对于��Z��H�口的程序设计，我们有多�U�技术方案可以选择�Q�在windows下有mfc�Q?net, wpf�Q�在linux下有gtk, qt, wxWidgets�Q�在mac下有cocoa, 但核心思想差不多，大多用到了mvc思想�Q�但mvc思想本��n也是一个组合思想�Q�它�l�合了策略模式，观察者模式等。对于这��L(f��ng)��一个设计思想来说�Q�它其实是一个对设计的高度抽象。我甚至可以做这样一个奇怪的思考：(x��)如果��mvc模式套用��C�h�w�上�Q�那么�h所看到的就是view�Q��h所惛_��的就是controller�Q��h所使用的便是model了，那么针对一个�h来说�Q�他的基本动作可能如下：(x��)看到东西->产生需�?>��L��工具来实现自��q��需求。所以我感觉�Q��Y件设计有时更像对人的行�ؓ(f��)模拟�Q��Y件系�l�更像是一个虚拟的人（�q�个人的智商要看你给他多��知识和能力�Q�，或者说�Q��Y件设计归根到底是以�h的认知来实现的，所以我们要划分模块�Q�要理清各个模块之间的关�p�，要考虑它们之间的相互媄(ji��ng)响，�q�要考虑他们之间的交互。如果各个模块之间关�p�L؜�׃��清，那么你将�?x��)的��C��个很烂的�pȝ��Q�置于会(x��)出现什么结果，那就不得而知了。�D个简单的例子�Q�试想一下如果你吃饭咬到舌头了，却发现屁股痛�Q�这是一件多么尴��的事情�?/p>

所以，软�g的设计实际上是一个很复杂的事情，一个高��的软�g更�ؓ(f��)复杂�Q�因��Z��要考虑太多的情况，一个�h是极其复杂的。但正如所有的物质都是��q��单的原子�l�成的，所有的复杂性都能划分成最��单最基本的东�ѝ��就好比操作�pȝ��q�样一个常人很难企�?qi��ng)的东西�Q�其实最底层也就六个操作�Q�引用linux创始人linus的话来说��是�Q?ldquo;你在UNIX上完成的大部分�Q务都是通过六个基本操作完成的，它们被称�?�pȝ��呼叫"�Q�system call�Q�。第一个基本操作是"创徏子进�E?�Q�fork�Q�，一个程序把自��n完全复制出来�Q�这样你��有了两个相同的拯��。第二个基本操作是复制出来的�E�序�Q�再用一个新��目替换自己。其他四个基本系�l�呼�?-打开、关闭、读和写--都是��Z��讉K��文�g的。这六个�pȝ��呼叫便组成了UNIX的简单操作。然后，你只需在程序之间创造出交流渠道�Q�pipes�Q�，��p��解决复杂的问题�?rdquo;�Q�那么归�l�到��n上，也就是那么几�U�：(x��)�z�d��Q��n体活动和思维�z�d��Q�，新陈代谢�Q�睡觉（�U�属个�h��x��勿喷�Q��?/p>

记得以前看bbc的纪录片《�؜沌理论》中讲到囄��的一�D�，囄��曄��提出一个伟大的构想�Q�自然界�׃��个最��单的数学公式�l�成。这个理��Z��q�了后来�?ldquo;��h��理论”�?ldquo;分�Ş�?rdquo;的研�I�和发展�Q�包括著名的“蝴蝶效应”�Q�也�?ldquo;��h��理论”有关。我们都知道�Q�图灵被�U�Cؓ(f��)“计算��Z��?rdquo;�Q�而现代的软�g设计�Ҏ(gu��)��和这�U�构惌��定存在千丝万�~�的联系。所以，我认为，软�g设计如果是一�U�把问题搞复杂的设计�Q�那��是一个失败的设计。��Y件设计应该是��一个复杂的�pȝ��一步一步划分成“原子”的过�E�，�?span style="color: #339966;">软�g架构的目标应该是使每一个分块都�Ҏ(gu��)��理解而且�Ҏ(gu��)��改变�Q�所谓的可维护性和可扩展性）�?/p>

而对于�h来说�Q��h生活在一�?ldquo;实体”的世界里�Q�如果把人类的历史看作一天，那么人拥有真正的思想是在一分钟以前�Q�所以上帝无法阻止�h�cȝ��“面向对象”的方式来�q�行软�g设计�Q�也无法��L��E�序员用mvc的思想来实��C��个��Y件系�l�，因�ؓ(f��)�q�一切看��h��理所当然。所以，无论你的技术多么高��，我都可以惌��你在面对一堆复杂的��法和一堆鲜�zȝ��对象的时候的不同感受�Q�因为我也可以感同��n�?)。所有的人都喜欢用简单的方式解决问题�Q�如果你不是�Q�那你也许是公务员，:)�Q�，更喜�Ƣ用��单的方式解决复杂的问题，那样�?x��)有成就感，�E�序员是最��x��例。�ؓ(f��)什么说一个会(x��)��h��的程序员是一个好的程序员�Q�那是因为程序员的偷懒是寚w��题的抽象和扩展，对之前冗长而繁琐的解决问题的方式徏立一个更为宽泛的适用模型�Q�从而应对类似重复的问题。而所谓的抽象�Q�便是思维的结晶。其实，抽象在各行各业都有应用，只不�q�在软�g开发领域，�q�个词被提及(qi��ng)的非�怹��q�范非常之响亮，以至于成了某些编�E�语�a�的关键字。其实抽象是一个很宽泛的概念，它是一�U�对事物本质的提取过�E?/strong>�Q�《数据结构》中有这��L(f��ng)��定义�Q�，所以我觉得在��Y件设计中的抽象，可以�q�用到其他领域，在其他领域中的抽象，也能应用到��Y件设计中来。所以，没必要惊讶图灉|��个数学家�Q�或者唐�U�_�d也是数学�?..�Q�因��Z��本质上来��_(d��)��数学�q�门�U�学��是一�U�抽象科学，把自然界抽象成数学模型，而计��机��是�Ҏ(gu��)��学抽象模型的模拟器�?/p>

胡说了一大堆�Q�也不知从哪儿来的灵感，但作��Z��个��Y件工�E�师�Q�我觉得�q�些东西是应该而且值得��L��考的。上�ơ看��C��则博文讲刎ͼ��q�个世界�׃��U��h推动�Q�科学家�Q�艺术家�Q�工�E�师。也许这�U�说法�ƈ不一定正��，但至��说明了一个观点：(x��)工程师想要实��C��U�的��品，必须懂得�U�学家和艺术家的抽象�Q�因为那是他们的思维�l�晶。�?span style="color: #339966;">一个好的工�E�师�Q�从某种�E�度来说�Q�也是一个科学家或者一个艺术家�?/p>

上一节我们创��Z��自己的第一个MVC3��目�Q��ƈ了解了Controller和View的添加方法。今天我们将仿照大米�q�利�|?/a>注册模块写个��例子，来进一步了解Model、Action、Form�{�相兛_��宏V�?/p>
�?strong>情景假设�?/p>

首页--�Ƣ迎��面�Q�简单介�l�大�c��利网�Q��ƈ提供注册链接�Q?
注册--用户使用�|�站之前要先注册��Z��(x��)员，注册��面�q�要对用户填写的信息�q�行有效性验证；



注册完成--完成之后�?x��)蟩转到一个提�C�页面，�q�向用户邮箱发送一��邮件�?/li>

一. 首页

1. ��上一节的Index��面用作首页�Q�再��d��一些说明文字�?/p>
首页 View代码
@{
    ViewBag.Title = "首页";
}
<h2>@ViewBag.helloh2>
<p>大米�q�利�|�提供淘宝网�{�多家商城的�q�现优惠�Q?span style="color: #0000FF;"><br/>
    �q�现比例高，提现速度快，注册�?元，�?元提现�?span style="color: #0000FF;">p>
<p>�Ҏ(gu��)��注册p>

接下来我们就要�ؓ(f��)“�Ҏ(gu��)��注册”提供链接��面了�?/p>
�? ��d��注册��面

1. 创徏数据Model

MVC中的M代表的领域模型，是应用程序中极其重要的部分之一�Q�一个设计完好的MVC��目往往从设计完好的model开始，然后在此基础上��l�添加controller和view。在我们的项目中�Q�model是对现实世界对象的封装，定义规则、处理等�{�。具体实现时Model一般就是对��目中通用性对象的属性、方法进行封装而来的C#�c�，然后controller和view以一定的方式暴露�l�客��L(f��ng)��?/p>
接下来我们添加一个用户信息的model�c�：(x��)右键models文�g�?>Add->Class->UserInfo.cs->Ok.

UserInfo.cs Code
///

    /// 注册用户实体
    ///

    public class UserInfo
    {
        ///

        /// 自动�~�号
        ///

        public int Id { get; set; }

        ///

        /// 用户�?br>        ///

        public string UserName { get; set; }

        ///

        /// 密码�Q�明文简单示例）
        ///

        public string Password { get; set; }

        ///

        /// qq��L(f��ng)��
        ///

        public string QQ { get; set; }

        ///

        /// 邮箱地址
        ///

        public string Email { get; set; }
    }
2. ��d��Action

在IndexController中添加新的action�Q?/p>
        //注册
        public ActionResult Register()
        {
            return View();
        }
3. ��d��强类型View

创徏view�Q�强�c�d��view目的是展现针对具体类型的实体�Q�指定具体类型之后MVC�?x��)��?f��)其提供许多快��L(f��ng)��操作。需要注意的是，在添加强�c�d��View之前�Q�我们要先编译整个MVC��目�Q�否则添加View时就�?x��)找不到先前��d��的UserInfo实体�?/li>

��d��步骤�Q?/p>
在Register Action代码块内右键->Add View->选中 Create a strongly type view复选框->Model class下拉框选择UserInfo->提供的模杉K��择Empty->Add。如下图所�C�：(x��)

��d��完成之后我们发现新添加的View是以@model的Razor代码开头的。接下来我们��会(x��)看到�Q�这正式强类型view以及(qi��ng)它能提供诸多便捷的关键所在�?/p>
三、编辑表�?/font>

1. View代码

<h1>大米�q�利�|?span style="color: #0000FF;">h1>
@using(Html.BeginForm())
{
    <p>用户名：(x��)@Html.TextBoxFor(m=>m.UserName)p>
    <p>密码:@Html.PasswordFor(m=>m.Password)p>
    <p>��认密码�Q�@Html.PasswordFor(m=>m.Password)p>
    <p>QQ:@Html.TextBoxFor(m=>m.QQ)p>
    <p>Email:@Html.TextBoxFor(m=>m.Email)p>
    <input type="submit" value="马上注册"/>
}

�q�里用的是Razor语法�Q��用过�E�中VS为我们提供了丰富的智能感知。以前不熟�?zh��n)�的同学可能�?x��)看着满眼的@�W�号不太自在�Q�用一�D�|��间就该上瘾了�Q�因为它真的很好上手。运行效果如下：(x��)

2. Html几个helper�Ҏ(gu��)��Q?/strong>
首先�Q�我们看一下页面源代码�Q?

��面源代�?/span>
<h1>大米�q�利�|?span style="color: #0000FF;">h1>

<form action="/index/register" method="post">

<p>用户名：(x��)<input id="UserName" name="UserName" type="text" value="" />p>

<p>密码:<input id="Password" name="Password" type="password" />p>

<p>��认密码�Q?span style="color: #0000FF;"><input id="Password" name="Password" type="password" />p>

<p>QQ:<input id="QQ" name="QQ" type="text" value="" />p>

<p>Email:<input id="Email" name="Email" type="text" value="" />p>

<input type="submit" value="马上注册"/>

form>

不难看出�Q�通过Razor语法中的Html helper�Ҏ(gu��)��Q�将Model中的属性用Input控�g形式展现出来了。例�?/li>

@Html.TextBoxFor(m=>m.UserName)

生成html�Ӟ��input控�gtype=”text”, id和name属性都被赋��gؓ(f��)"UserName“。对应html代码为：(x��)
<input id="UserName" name="UserName" type="text" value="" />

对于强类型view�Q�书写lamda语法时有着丰富的智能感知。如果不惛_��成lamda形式�Q�还可以�q�样 @Html.TextBoxFor(“UserName”)
Html.BeginForm�Q?/li>

代码格式�?span style="background-color: yellow;">@using(Html.BeginForm()){   …}�Q�通常使用using关键字是��Z��走出花括��h��释放较占资源的对象，而在�q�里可以理解为关�?lt;form>标签。生成form属性时�Q�默认的action�?x��)提交回当前的url�Q�而method默认讄��为post。最�l�生成的html源码为：(x��)
……
�?/p>
另外�Q�在WebForm开发时�Q�每个页面只允许使用一个服务端form�Q��ƈ且包含ViewState以及(qi��ng)postback逻辑�Q�而在MVC中是没有服务器端form�q�个概念的，没有ViewState以及(qi��ng)postback机制�Q�每个页面可以放�|�多个form�?/p>

Html.ActionLink:用来��d��action��面的链接，我们可以在首��ؓ(f��)“�Ҏ(gu��)��注册”��d��链接�Q?/li>

@Html.ActionLink("�Ҏ(gu��)��注册","Register","Index")

�? 表单提交

1. HttpGet和HttpPost:
��Z��接收�q�处理提交的表单数据�Q�我们还需要再��d��一个Register action�Q�这两个action的作用是�Q?

一个用来响应Http Get��h��Q?为action��d��HttpGet�Ҏ(gu��)�?也可以省�?�Q�Get��h��通常是用��L(f��ng)��一�ơ访问页面时�Q�通过该action初始化空白表单�?
一个用来响应Http Post��h��Q��ؓ(f��)acton�Ҏ(gu��)��d��HttpPost�Ҏ(gu��)��，Html.BeginForm()创徏的窗体默认被��览器处理�ؓ(f��)Post��h��。这个版本的action�Ҏ(gu��)��负责接收提交的表单数据�ƈ�q�行相应处理�?/li>

       [HttpGet]
        public ActionResult Register()
        {
            return View();
        }
        [HttpPost]
        public ActionResult Register(UserInfo userInfo)
        {
            return View("Complete",userInfo);
        }
2.Model Binding

在上面的post�Ҏ(gu��)��中，使用了MVC中一个非�怸�错的�Ҏ(gu��)�?--Model Binding�Q�它可以解析传来的数据�ƈ��其对应到领域模型的属性。其实这个Model Binding�q�程是双向的�Q�当创徏form数据�Ӟ��input控�g的值是�Ҏ(gu��)��与其name对应的model属性来赋值的�Q�反�q�来�Q�当提交form表单�Ӟ��通过model binding又可以根据input控�g的name属性来为model实体同名的属性赋��|��q�而提交到post action�Ҏ(gu��)��?/p>
五、表单验�?/font>

在MVC应用�E�序中，我们一般把验证��d��在model实体而不攑֜�用户界面�Q�这样只要我们在一处定义了验证规则便可以多处生效。ASP.NET MVC��d��体实现方式是�Q��?span style="background-color: yellow;">System.ComponentModel.DataAnnotations 中定义的�Ҏ(gu��)��，��其声明在model属性作为验证规则就可以生效了�?/p>
1. Model实体��d��验证规则
Model Validation Code
using System.ComponentModel.DataAnnotations;
namespace DamifanliMvc3.Models
{
    ///

    /// 注册用户实体
    ///

    public class UserInfo
    {
        ///

        /// 自动�~�号
        ///

        public int Id { get; set; }

        ///

        /// 用户�?br>        ///

        [Required(ErrorMessage = "误��入用户名")]
       [RegularExpression("^[a-zA-Z][a-zA-Z0-9]{2,14}$", ErrorMessage = "误��?-15位字母或数字")]
        public string UserName { get; set; }

        ///

        /// 密码�Q�明文简单示例）
        ///

        [Required(ErrorMessage = "误��入密�?/span>")]
        public string Password { get; set; }

        ///

        /// qq��L(f��ng)��
        ///

        [Required(ErrorMessage = "误��入QQ��L(f��ng)��")]
        [RegularExpression("[1-9][0-9]{4,}",ErrorMessage = "误��入正��的qq��L(f��ng)��")]
        public string QQ { get; set; }

        ///

        /// 邮箱地址
        ///

        [Required(ErrorMessage = "误��入邮��地址")]
        [RegularExpression(@"\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*",ErrorMessage = "误��入正��的邮箱地址")]
        public string Email { get; set; }
    }
}
2.ModelState.IsValid

我们可以在Controller中��用ModelState.IsValid来检验是否存在验证问题�?/p>
public ActionResult Register(UserInfo userInfo)
        {
            if(ModelState.IsValid)
            {
                return View("Complete", userInfo);   //Complete Action后箋创徏
            }
            return View();
        }

3.错误提示

当用戯��入不�W�合规则�Ӟ��我们可以在view中��用Html.ValidationSummary()来提�C�用戗��?/p>
@using(Html.BeginForm())
{
@Html.ValidationSummary()

用户名：(x��)@Html.TextBoxFor(m=>m.UserName)

    ……

}
该方法会(x��)在页面中攄��一�p�d��隐藏的li�Q�MVC可以令这些位�|�可见�ƈ昄��model验证属性中定义的错误信息，如下图所�C�。点�?y��n)L��册按钮时该页面不�?x��)进行蟩转，直到所有输入都�W�合规范为止。值得庆幸的是�Q�提交失败时之前填写的数据仍然会(x��)保留在页面中�?/p>

查看��面源代码：(x��)
<p>
用户名：(x��)<input class="input-validation-error" data-val="true" data-val-regex="误��?-15位字母或数字" data-val-regex-pattern="^[a-zA-Z][a-zA-Z0-9]{2,14}$" data-val-required="误��入用户名" id="UserName" name="UserName" type="text" value="" />
p>
六、注册完成页�?/font>

1.��d��Complete View:

在前面的post提交的Register中，我们已经�l�出了注册完成时要蟩转的目标”Complete”,�q�且传递了变量userInfo,接下来我们添加一个强�c�d��UserInfo�c�d��的View�?/p>

修改代码如下�Q?/p>
@model DamifanliMvc3.Models.UserInfo
@{
    ViewBag.Title = "注册完成";
}
<h2>注册完成h2>
<p>
    恭喜�Q��?zh��n)�已注册成功，请妥善保��注册信息�?x��)<br/>
    账号:@Model.UserName<br/>
    QQ:@Model.QQ<br/>
    Email:@Model.Email<br/>
    大米�q�利�|�祝�(zh��n)�购物愉快！
p>

2. 发送邮仉��知

在展�C�Complete View的同�Ӟ��我们使用WebMail�c�L��发送通知邮�g�?br>
@{
    try
    {
        WebMail.SmtpServer = "smtp.sina.com";
        WebMail.SmtpPort = 587;
        WebMail.EnableSsl = true;
        WebMail.UserName = "CathyChen";
        WebMail.Password = "damifanli";
        WebMail.From = "cathychen@sina.com";
        WebMail.Send(@Model.Email,"成功注册大米�q�利�|?,@Model.UserName+",�(zh��n)�已成功注册大米�q�利�|�，��?zh��n)�购物愉快�Q?);
    }
    catch
    {
        @:抱歉�Q�通知邮�g发送失败！
    }
}
��结�Q?/strong>

到这里，今天的学�?f��n)基本结束了。当然了�q�只是一个简单的�C�Z��Q�实际��用中�q�有很多可以改进的地方，比如��发送邮件功能放在单独的模块中调用而不是将代码块嵌在View中，以便重复使用�Q�另外，�q�里的错误处理��用的try…catch�Q�其实可以蟩转到单独的错误页面�?/p>

Reminder: TechCrunch Is Coming To Greenville, SC Tonight! (UPDATED LOCATION)

BoyXiao — Sat, 14 Jul 2012 03:50:00 GMT

For many a TechCruncher, the past week has been the same as most. Break some news, go to some events, turn the world on with your smile… you know the drill. But for John Biggs, Josh Zelman and I (and at times Matt Burns), this week has been a whirlwind of crazy awesome parties, Southeastern drawls, incredibly cool startup pitches, and an amazing amount of both pork and beer.

It’s the Southeast Meetup tour ya’ll, and it’s coming to a close tonight. We’ve hit Atlanta, Raleigh-Durham, Charlotte, and now we’re headed to Greenville, South Carolina. (As a side note, the location has changed. We’ll now be holding the event at The Overlook Grill – 601 South Main Street Greenville, SC 29601.)

It’s been a long ride, but a great one. In fact, we’ve invited at least two dozen companies to apply for Disrupt — yep, that’s how cool these companies are.

It’s amazing to look for startups outside of Silicon Valley and Silicon Alley and find an abundance of exactly that. Hopefully, the last spot on this totally successful meetup tour will bring more of the same.

Again, the location has changed, so if you’re coming tonight be sure to familiarize yourself with The Overlook Grill – 601 South Main Street Greenville, SC 29601.

Kickstarter, M.D.: MedStartr Finally Brings Crowdfunding To Health Projects

BoyXiao — Sat, 14 Jul 2012 03:50:00 GMT

The Crowd is on the loose. Thanks to the JOBS Act, mainstream attention came to crowdfunding this year, and platforms like Kickstarter and Indiegogo have been benefitting in kind. Kickstarter, in particular, has seen an exponential increase this year in how much capital its projects have been able to raise. (Exhaustive post on the subject here.) The Crowd has pledged $275 million to some 63,000 Kickstarter projects to date, and companies of all breeds are now using these platforms as launchpads and for a little proof of concept.

But, sadly, you know who really isn’t benefitting from the crowdfunding boom? Healthcare startups. Brian Dolan of MobiHealth points out that, in fact, Kickstarter officially prohibits health, fitness, and medical projects. Healthcare is absolutely jonesin’ for innovation, and there are tons of cool health companies trying to change the world — some of them even a little sexy and consumer-facing.

That’s why serial healthtech entrepreneur Alex Fair and founding Kickstarter product manager Mike Pence have set out to give health-focused entrepreneurs and projects a Kickstarter of their own. Medstartr, which launched in beta today, is a crowdfunding platform designed specifically for healthcare companies, providing startups with a vehicle to market their wares, generate awareness and raise capital — direct from strangers, investors, and Doogie Howsers alike.

Sure, support for healthtech startups — and their small victories — are worth noting just on principle. But, MedStartr isn’t aiming just to be a lazy port of Kickstarter/Indiegogo to healthcare. Fair was inspired to create Medstartr not only because of the rejection his healthtech ideas found on Kickstarter, but also because of the much-ballyhooed JOBS Act. The legislation legalized funding in startups by non-accredited investors and has likely changed early-stage investing for good.

The SEC is still working out the specifics of the regulations aimed at bringing some order to the wild and wooly west that will be Crowdfunding 1.0. In particular, the government must decide on where to cap the amount of capital businesses can raise via crowdfunding platforms, whether or not they’ll be able to raise cash by selling securities, etc. And, as it goes with medical biznass, the regulations will have specific measures (i.e. restrictions) on health businesses, with some of those being determined by the FDA.

Until the regulations are released, crowdfunding platforms have to wait and over-prepare if they can. In the meantime, MedStartr is limiting the amount of capital its projects can raise to $40,000 and, like the Kickstarters of the world, MedStartr is non equity-based, instead offering market validation and non-dilutive funding as value propositions for startups. Once SEC rules are set, however, Fair tells us that the company will establish an equity model.

In this way, the co-founders have plenty of plans for how the platform will differentiate from the big names, but some are still incipient — in part because the platform was founded about three months ago and in part because some may be subject to change.

For starters, Fair has nearly two decades worth of experience in healthtech, health IT, and consulting, which he plans to leverage to help MedStartr’s health projects not only reach their targets but find follow-on funding and support. Of course, while it will become trickier at scale, entrepreneurs can expect much more of a hands-on, or proactive, approach from the founders in comparison to Kickstarter.

They have already started to, and plan to continue with an events-based model, in which MedStartr will hold mini-conferences (with panels, etc.) in various cities, allowing project creators to set up booths and interact and network with potential investors. Like a MeetUp for Medics.

Fair also sees some bigger potential industry benefits than the requisite low-cose inbound marketing that is typically a built-in perk of crowdfunding platforms. Up to this point, hospitals, doctors, patients, and healthcare companies have largely lacked public resources by which to discover, interact with, and invest in health companies.

Many health or medical projects also inherently have highly motivated and engaged user bases (see 23andMe and CureTogether for examples), as they often promote healthier lifestyles, provide support for people in need or suffering from illnesses, try to find cures, and reduce medical and insurance costs. All of which can be emotional issues.

A crowdfunding platform for health projects allows the many who, say, want to help make or find ways to contribute to the health of loved ones to participate actively in the process. And feel a direct connection to projects and their founders and feel they’re making a difference. MedStartr launched with both a diabetes project and a project that supports those with STDS, for example.

On top of this, it seems that MedStartr also has the potential to incorporate some elements of AngelList and healthtech incubators like Rock Health and Blueprint. The crowdfunding platform can function as a screening ground for investors. Startups turn their project pages into pitch platforms, incorporating video, images, etc., and investors can interact and connect with the entrepreneurs through the site.

MedStartr can also incorporate partner programs that allows doctors, CIOs, or executives of health companies to use MedStartr for validation and deal flow and to support them. If they like the idea, they can offer up a deal. If they sign up a certain number of physicians, attract a certain amount of feedback and hit a set target for funding, then a CTO of Pfizer, say, could reward them by funding their first pilot study. The company already has a big pharma company and medical society on board.

All that being said, MedStartr’s current incarnation owes a lot to the popular crowdfunding platforms. Its name (and the design of its site) make that apparent enough. But, if MedStartr is able to deliver on even half of its goals, it can become more than a valuable, feel-good medtech experiment. VCs and investors want to invest in great healthtech companies, and this gives them a great way to interact with health startups and source potential investments.

It’s not clear that there can be enough cross-over from mainstreamers and consumers to give MedStartr the lift it needs to hit scale, rather than remaining a purely industry resource. But if they play it well, and turn it into a viable Kickstarter/MeetUp/AngelList hybrid for health startups, why not?

P2P Storage Startup Space Monkey Raises $2.25M Led By Google Ventures And Venture51

BoyXiao — Sat, 14 Jul 2012 03:50:00 GMT

Space Monkey, the startup offering a peer-to-peer alternative to cloud storage services like Dropbox, just raised $2.25 million in a seed round of funding.

The company says that it’s combining the benefits of both local storage and the cloud. Every Space Monkey customer gets their own storage device, so they can access their files without having to worry about download times or pay the higher cost of cloud storage (which can become an issue when you’re talking about large media files like videos). Copies of those files are also distributed in chunks to other Space Monkey devices, allowing for remote access and backup.

I first wrote about the company when it won the best new startup prize at the Launch conference in March. At the time, some readers pointed out that there are some open source solutions trying to do something similar. However, there’s a big difference between an interesting open source project and a consumer-grade service and company. Product Guy Clint Gordon-Carroll (yes, that’s his real title) says that the real challenge is creating something that’s actually compelling to a large audience. For example, he notes that by introducing the Space Monkey device, users no longer need to keep their computers online at all times.

In the first week alone, Gordon-Carroll says Space Monkey saw 10,000 sign ups. The company is now planning to ship the first devices this fall.

At the conference, Space Monkey had already raised $750,000. That amount was rolled into the new seed round, which was led by by Google Ventures and Venture51. Here’s the full, incredibly long list of investors (or at least those who can be disclosed publicly):

Polaris Venture Partners

Morado Ventures

Social + Capital Partnership

Andreessen-Backed LearnSprout Wants To Help Developers Unlock Educational Data

BoyXiao — Sat, 14 Jul 2012 03:50:00 GMT

APIs are marching into education, and it’s about time. Education is rife with legacy infrastructure, with one of the primary offenders being Student Information Systems (SIS). Schools use these systems to store huge amounts of sensitive student information (class lists, attendance, grades and allergies, etc.), but they differ widely from school to school, which, among other things, forces developers to manually integrate with each unique system, making it difficult for their cool educational software or apps to achieve any kind of scale.

LearnSprout, a recent graduate of the education-focused startup accelerator Imagine K12 wants to help both schools and developers unleash those opaque educational data silos with the help of a few clean, standardizing APIs. While the recently-launched startup is not alone — Y Combinator-backed Clever launched a similar platform last month — LearnSprout now has the benefit of some notable investors to help fuel its fires.

The startup is in the process of closing its first round of funding with participation from Andreessen Horowitz, Formation 8 (a new VC fund headed by Palantir co-founder Joe Lonsdale), Benjamin Ling, Philip Fung and Luke Shepard — to name a few. LearnSprout is in the process of adding a few more investors and is hoping to cap the round at around $1 million.

LearnSprout is also one of eight companies (and the only education startup) to be accepted into the inaugural cohort of Code For America’s accelerator program, which provides early-stage businesses with a grant, mentoring, and introductions to tech-savvy decision makers in local and federal government in an effort to help them grow civically-minded businesses.

Founded in January this year by Franklyn Chien, Anthony Wu, and Joe Woo, veterans of Facebook, Google, and Microsoft respectively, today LearnSprout is already working with 40+ schools and another 200+ schools are in the pipeline, and it’s begun to generate revenue to boot. All in all, not bad progress for six months.

But, as it so often goes, this isn’t where the team initially planned to end up. Chien tells us that, going into Imagine K12, LearnSprout had begun to build a modern learning management system-student information system hybrid that was intended to be v2.0 of Blackboard — something not too dissimilar from Instructure’s Canvas. But, it wasn’t long before the founders came to the realization that getting schools to dump their existing systems was basically a fool’s errand.

Rather than shell out money for new systems or software, schools tend to make due with what they have, adding ad hoc fixes as they go. There are over 100 student information systems in operation today, each of them built in Frankenstein ways to save costs. Teachers end up having to manually enter data themselves, making transferring, aggregating, and gaining insight into these data silos a nightmare.

Because schools aren’t eager to budge, the best fix is to give them (and developers) one set of APIs that allows them to keep their systems in place while making their data portable and fluent in a universal language. The startup’s APIs essentially create a secure channel through which developers and schools can transfer the sensitive information from their student information systems.

LearnSprout removes the pain for developers of having to manage CSV files, exports and FTP servers, and removes manual data entry. As extra incentive for schools, LearnSprout handles all data integration with the student information systems itself, whether it’s CSV or direct database connection. The team is also providing schools with two applications that come on top of its APIs and work right out of the box — one of them being a school-wide emergency notification system, for example. The purpose of including these apps, Chien says, is to showcase the power of the platform, give schools a way to get used to the new system, while giving developers an archetype with which to work.

LearnSprout also handles data duplication, serving developers and schools with only the most up-to-date information. What’s more, for schools, it’s all free. LearnSprout offers them one-click install to get them started, charging developers either with a flat fee or offering a revenue share based on the number of integrations. If they bring a new school to LearnSprout, however, integration is free. Right now, Chien says that the startup is already working with about 70 percent of the SIS in operation in the U.S. and is hard at work on covering the remainder.

In terms of its plan going forward, the team is already thinking beyond the U.S., eyeing tons of potential abroad and plans to leverage contacts from Andreessen and Formation 8 to begin taking international steps.

Bing Fund: Microsoft Officially Launches Its New Angel Fund And Incubator Program

BoyXiao — Sat, 14 Jul 2012 03:48:00 GMT

This wasn’t exactly a secret anymore, but Microsoft just officially unveiled its Bing Fund, a new angel fund and incubator program sponsored by Bing and “backed by the experience, expertise, and resources of Microsoft.” The idea here, says Microsoft, is to “partner with like-minded entrepreneurs—great talent that is innovating online to solve big problems and create amazing new experiences.” The fund is looking for startups that focus on mobile and web experiences and which provide “both inspirational vision” and the “ability to execute.”

Microsoft also recommends that the startups that plan to apply for this program already have a working prototype and a broad plan for how to tackle the problem they are trying to solve and what the market for their products looks like.

Startups will be accepted on an on-going basis and the Bing Fund is also looking to partner with existing accelerators to find potential candidates for the new fund. The plan is to focus on just a few startups at a time and as companies graduate, new ones will be accepted to fill their spots. Microsoft doesn’t promise that it will acquire successful startups, but the company says that “acquisition is always a possibility.”

Besides receiving funding, the startups that are accepted into this program will receive subsidies to use Bing’s APIs and also access to technologies developed by Microsoft Research. Microsoft also plans to provide these startups with mentors inside the company and promises that the IP and product will remain in the hands of the participating companies.

Startups that are located in Seattle will also be able to take advantage of co-workspace in Bellevue (a few miles away from the company’s main Redmond campus), where the Bing Fund team and Microsoft’s machine learning, search and data experts are located.

It’s worth noting that the Bing Fund does not require companies to use development stack, but it does encourage startups to participate in its BizSpark program, which gives companies that are less than three years old and make less than $1 million per year discounted access to its development tools. BizSpark already works with TechStars, by the way, to make $60,000 worth of Azure compute and storage services available to the companies in its Microsoft Accelerator for Windows Azure program.
