<h2>Better Practice</h2>
<p>
  Yeah, hard to be the best, I think depend on the Enviroment or what you try to
  build the Practice of how to build Xamarin might end up differently.
</p>
<h3>
  <strong>avoid use <code>x:Name=</code> at the control</strong>
</h3>
<p>
  It's better to use Xamarin's MVVM model to bind value to the UI, so you don't
  have dependency of UI and backend Model. For instance, if you have x:Name on
  your XAML, you C# side is using that name, then if you just remove the entire
  XAML section and replace the new one, build failed. Your XAML is tired to the
  XAML.cs code.
</p>
<pre class="language-xml">
  &lt;Entry x:Name="MyName" Text="{Binding MyNameAtModel, Mode=TwoWay}" Placeholder="My Name is" Keyboard="Text"&gt;
                                &lt;/Entry&gt;
</pre>
<h3>Use <code>CachingStrategy="RecycleElement"</code> for ListView</h3>
<p>
  Use RecycleElement for ListView's CachingStrategy, this is better performance.
</p>
<pre>
    &lt;ListView CachingStrategy="RecycleElement" 
                              &gt;
</pre>

Xamarin- How to Create Master and Detail Page


<h1>Setup Xamarin</h1>
<p>
  If you want to build app for iOS, android and windows and still want to use C#
  and Visual Studio, also want to use maximum native API as possible, then
  Xamarin could be a very good choice for you.
</p>
<p>
  Well, that's the good part, however at 2017 right now, I think use Xamarin,
  you have to do lots research, check example apps, check documentation, but
  lots of documentation of describe certain technology is not very clear, end up
  like regular code comment, just describe what's the class, member and lacking
  the actual example.
</p>
<p>
  However, again, C#, visual studio able to use iOS simulator (Required Mac) are
  very good point. If you're mainly backend, C# developer not much known about
  front-end, go with Xamarin, but if you're ok with front-end technology, CSS,
  Javascript, Html, you could try Phonegap, which so far just a shell build
  js/html inside native app, or iOnic(angular2), or I would say try the React
  Native, which it will compile React Native to native Android and iOS.
</p>
<p>
  This blog shows how to setup Xamarin on Windows, first this example is based
  on windows 10 and use visaul studio 2015.
</p>
<h3>Xamarin download on Visual Studio 2015</h3>

  is very simple, you don't have to do most of the thing, I'll just explain what
  main software will be installed with this Xamarin. So
  <strong
    >Report errors and usage information to help Xamarin improve my
    experience.</strong
  >, I usually won't check this , because it might affect my pc's performance,
  but it's good if you want to send your data to help Xamarin to build better
  product.

<h3>Close Visual Studio</h3>
<p>
  During Xamarin installation, you have to close your Visual Studio, becaue it
  has to installed plugin to your Visual Studio.

  Now, you just need to wait the whole installing to be finished, notice from it
  will install Android, Haxm, simulator, and Java. So the Java SDK it's for
  android, android require Java to be installed, for example when you build your
  android app, android use Java to create keystore and for generator Android
  <code>APK</code> file to android app store.

  Basically you have to add to <code>Path</code> to Environment Variables's
  <code>Path</code>.
</p>
<h3>How to enable gulp?</h3>
<p>
  For gulp, you will have to add following path to Path System Variables, so
  command line will recognize npm's global path. Also install gulp so run
  command as gulp will be recognized. At the end, you'll have to restart the
  command line if you have not restart command line after change the system
  variables.
</p>
<ul>
  <li>Add path to windows System Variables</li>
  <ul>
    <li>%USERPROFILE%\AppData\Roaming\npm</li>
    <li>C:\Program Files\nodejs\</li>

<h3>How to enable bower?</h3>
<p>
  If you already setup gulp, then the only think you have to do is run npm for
  bower as global.
</p>
<ul>
  <li><code>npm install -g bower</code></li>
</ul>
<h3>Git is not recognized too?</h3>
<ul>
  <li>
    Go to windows' Enviroment Variables and edit the the path variables, make

<h2>How to Use git to commit to GitHub</h2>
<p>
  Following example is for windows enviroment and command is use windows'
  Command Prompt.
</p>
<p>
  First you need to setup the git's user and email, check the current user and
  email by run following command.
</p>
<pre class="language-xml">
&gt; git config --list
</pre>
<p>
  If the <code>user.name</code> or <code>user.email</code>is not there, try run
  following command to set username and email address.
</p>
<pre class="language-xml">
&gt; git config --global user.name "test"
&gt; git config --global user.email "test.email"
</pre>
<p>
  Now, you're ready for git check-in locally, if you type
  <code>git commit -m "test commit"</code> for commit. Type
  <code>git log</code>, you'll see the log history of the git commit.
</p>
<p>Init Git</p>
<p>Run this command to initialize the git.</p>
<pre class="language-xml">
&gt; git init
</pre>
<h3>Git local commit</h3>
<pre class="language-xml">
&gt; git add .
</pre>
<pre class="language-xml">&gt; git commit -m "Initialize repository"</pre>
<h3>Commit to GitHub</h3>
<pre class="language-xml">&gt; git remote add origin {your github address}
&gt; git push -u origin master<br />
</pre>
<h3>Clone Git from Github</h3>
<pre class="language-xml">&gt; git clone {your github address}<br /><br /></pre>
<h3>Clone Git origin url A then Check-in to Git origin url B</h3>
<pre
  class="language-xml"
>&gt; git clone {url A}<br />&gt; delete git folder<br />&gt; git remote set-url origin {url B}<br />&gt; git pull {url B}<br />&gt; git push -u origin master<br /><br /></pre>
<p>
  In case of <code>Git push</code> doesn't work, and you tried possible solution
  already, then you could also try <code>git push --force</code>, to force
  update to the remote location.
</p>

Few Commands About Use Git to Commit to GitHub


<h2>How to use MongoDB text search</h2>
<p>
  MongoDB provide text search function since 2.4, this blog will show how to use
  mongodb text search.
</p>
<p>
  All the example at following is run based on MongoDB version, 3.0.5. Also, I'm
  using Robomongo (0.8.5) to run all the MongoDB command.
</p>
<p>
  I also have code snippet about how to use Mongoose with text search, but I
  recommend at least use 2.6, seems like 2.4 with Mongoose has some problem.
</p>
<h3>Stop Words, Stemming in MongoDB text search</h3>
<p>
  Before jump into how to use MongoDB text search, we need to understand how
  MongoDB do stop words and stemming. <strong>Stop</strong> in MongoDB is, let's
  say you have "I like apple", stop wold will be <strong>apple</strong>.
  <strong>Stemming</strong> is like "cook cooking cooks", so MongoDB text engine
  will index cook.
</p>
<blockquote>I like apple, also I enjoy cooking.</blockquote>
<p>
  Above example, MongoDB will index <code>apple</code> and <code>cook</code>,
  There is very good blog about this topic,&nbsp;<a
    href="https://blog.codecentric.de/en/2013/01/text-search-mongodb-stemming/"
    target="_blank"
    >text-search-mongodb-stemming</a
  >.
</p>
<p>&nbsp;</p>
<h3>Now, let's get started how to use MongoDB text search</h3>
<h6>Get MongoDB's version</h6>
<p>This command will tell you what version of MongoDB you're using.</p>
<pre class="language-javascript">
db.version()
// 3.0.5
</pre>
<h6>Get Current MongoDB database name</h6>
<p>
  This will return your current db name. Before you run you query you need to
  check you're running to the correct mongodb or not right?
</p>
<pre class="language-javascript">
db.getName()
// the current database name.
</pre>
<h6>Check Index of current collection</h6>
<p>
  You can run following command, if you want to check your collection had add
  text index or other index or not.
</p>
<p>
  Following example is how I check my collection
  <code>Posts&nbsp;</code>contains any index or not.
</p>
<pre class="language-javascript">
// You run this
db.posts.getIndexes()
</pre>
<pre
  class="language-javascript"
><code>// Then will some result like this or if there's no index then just empty json. Now as you can see following example contains no text search index.
{
    "0" : {
        "v" : 1,
        "key" : {
            "_id" : 1
        },
        "name" : "_id_",
        "ns" : "dake-tech.posts"
    },
    "1" : {
        "v" : 1,
        "unique" : true,
        "key" : {
            "slug" : 1
        },
        "name" : "slug_1",
        "ns" : "dake-tech.posts",
        "background" : true,
        "safe" : null
    }
}
</code>
</pre>
<p>
  Now, we're going to add text index to this collection.First the collection
  <code>Posts</code> looks like following. I'd like to add create text index to
  <code>content.brief &amp; content.extended &amp; title</code>
</p>
<pre class="language-javascript"><code>
{
    "_id" : ObjectId("535cc04cd06eabf033ee36bc"),
    "__v" : 0,
    "author" : ObjectId("535c4fe25115d24c0c4cf84b"),
    "categories" : [],
    "content" : {
        "brief" : "&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;Looks like&amp;nbsp;http://embed.ly/ is greate site, if I want to create something with URL. It'll get the short version of the url's detail. I have thought about imprement these kind of stuff, but since somebody already create this, why not just use it.&amp;nbsp;&lt;/p&gt;
&lt;pre class="language-javascript"&gt;&lt;code&gt;\r\n&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;pre class="language-javascript"&gt;&lt;code&gt;\r\n&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;Nextime, i'll post some detail when I use it.&lt;/p&gt;
&lt;pre class="language-javascript"&gt;&lt;code&gt;",
        "extended" : ""
    },
    "publishedDate" : ISODate("2014-04-01T07:00:00.000Z"),
    "slug" : "embedly-get-url-link-detail",
    "state" : "published",
    "title" : "embed.ly - Get url link detail"
}
</code>
</pre>
<p>First, let's add text index to <code>title</code></p>
<pre class="language-javascript">
db.posts.ensureIndex({title: "text"});
</pre>
<p>
  After I create text index to the <code>title</code>field, and run
  <code>db.posts.getIndexes()</code> again to check my index, I got following
  new added index. Cool, I had added text index to my Posts.Title.
</p>
<pre class="language-javascript">
    "4" : {
        "v" : 1,
        "key" : {
            "_fts" : "text",
            "_ftsx" : 1
        },
        "name" : "title_text",
        "ns" : "dake-tech.posts",
        "weights" : {
            "title" : 1
        },
        "default_language" : "english",
        "language_override" : "language",
        "textIndexVersion" : 2
    }
</pre>
<p>
  Now, mongodb also has YouCollection.validate() which will validate your
  index.So when I run <code>db.posts.validate()</code> I got following result
  about my title field's text index. So cool right, the
  <code>"dake-tech.posts.$title_text" : 1464</code> is telling you the
  post.title indexed <code>1464</code>keys words.
</p>
<pre class="language-javascript"><code>
{
    "ns" : "dake-tech.posts",
    "datasize" : 4.72926e+006,
    "nrecords" : 325,
    "lastExtentSize" : 1.67772e+007,
    "firstExtent" : "0:ef000 ns:dake-tech.posts",
    "lastExtent" : "0:351000 ns:dake-tech.posts",
    "extentCount" : 4,
    "firstExtentDetails" : {
        "loc" : "0:ef000",
        "xnext" : "0:111000",
        "xprev" : "null",
        "nsdiag" : "dake-tech.posts",
        "size" : 8192,
        "firstRecord" : "0:ef0b0",
        "lastRecord" : "0:f0eb0"
    },
    "lastExtentDetails" : {
        "loc" : "0:351000",
        "xnext" : "null",
        "xprev" : "0:151000",
        "nsdiag" : "dake-tech.posts",
        "size" : 1.67772e+007,
        "firstRecord" : "0:3510b0",
        "lastRecord" : "0:591230"
    },
    "deletedCount" : 5,
    "deletedSize" : 1.44095e+007,
    "nIndexes" : 5,
    "keysPerIndex" : {
        "dake-tech.posts.$_id_" : 325,
        "dake-tech.posts.$slug_1" : 325,
        "dake-tech.posts.$state_1" : 325,
        "dake-tech.posts.$publishedDate_1" : 325,
        "dake-tech.posts.$title_text" : 1464
    },
    "valid" : true,
    "errors" : [],
    "warning" : "Some checks omitted for speed. use {full:true} option to do more thorough scan.",
    "ok" : 1.0000000000000000
}
</code>
</pre>
<h6>Now, let's do text search</h6>
<p>
  When you type <code>db.posts.runCommand("text", {search: "mongodb"})</code>,
  you might get result as following.
</p>
<pre class="language-javascript"><code>
{
    "ok" : 0.0000000000000000,
    "errmsg" : "no such command: text",
    "code" : 59,
    "bad cmd" : {
        "text" : "posts",
        "search" : "mongodb"
    }
}
</code>
</pre>
<h3>What's going on, doesn't work!</h3>
<p>
  You might able to try following, go to admin enable the text search. However
  you will still get the same result. What happening is following command looks
  like works for the old MongoDB, maybe 2.4 to 2.6. However, if you use latest
  MongoDB (3.0 or above), text search is enable by default, and
  <code>runCommand("text", </code> is no longer exist.
</p>
<pre class="language-javascript">
use admin
db.runCommand({setParameter: 1, textSearchEnabled: true})

db.posts.runCommand("text", {search: "mongodb"})

{
    "was" : true,
    "ok" : 1.0000000000000000
}
</pre>
<h3>So, what's I do?</h3>
<p>
  If you mongodb version is 3.0 or above like my current MongoDB, 3.0.5. You can
  try following.
</p>
<pre class="language-javascript"><code>
db.posts.find( { $text: { $search: "javascript" } } )
</code>
</pre>
<p>Also, following is the result I got. Awesome, right!? you got 12 results.</p>
<p>
  <img
    class="img-responsive"
    src="https://d1p0mp3f1fx0hz.cloudfront.net/_0eg17u58c.png"
    alt=""
  />
</p>
<p>
  Now, I'm going to add text index to my result of fields,
  <code>content.brief</code> and <code>content.extended</code>, So you type...
  <code>db.posts.ensureIndex({'content.brief': 'text'});</code>. Then you got
  this error, what's going on!!? I can only add once!?
</p>
<pre class="language-javascript"><code>
{
    "createdCollectionAutomatically" : false,
    "numIndexesBefore" : 3,
    "errmsg" : "exception: Index with pattern: { _fts: \"text\", _ftsx: 1 } already exists with different options",
    "code" : 85,
    "ok" : 0
}
</code>
</pre>
<p>
  The result is, at current version 3.0.5, you can only add one text index, if
  you want to add multi fields for text search, you could do as following.
  First, you run <code>db.posts.dropIndex('title_text')</code>, so you can drop
  the old text index.
</p>
<p>This is the result you will get.</p>
<pre class="language-javascript"><code>
{
    "nIndexesWas" : 5,
    "ok" : 1.0000000000000000
}
</code>
</pre>
<h6>Add text index to multi fields</h6>
<p>Now, you can run following command.</p>
<p>
  <code
    >db.posts.ensureIndex({title: 'text', 'content.brief': 'text',
    'content.extended': 'text'});</code
  >
</p>
<p>Once shows result as following, the new index is added.</p>
<p><code>Inserted 1 record(s) in 27ms</code></p>
<p>
  If you run <code>db.posts.getIndexes()</code>, you can verify you text index
  is added.
</p>
<pre class="language-javascript"><code>
    "4" : {
        "v" : 1,
        "key" : {
            "_fts" : "text",
            "_ftsx" : 1
        },
        "name" : "title_text_content.brief_text_content.extended_text",
        "ns" : "dake-tech.posts",
        "weights" : {
            "content.brief" : 1,
            "content.extended" : 1,
            "title" : 1
        },
        "default_language" : "english",
        "language_override" : "language",
        "textIndexVersion" : 2
    }
</code>
</pre>
<p>
  Also, if you the index validation <code>db.posts.validate()</code>, you can
  see that new text index has index <code>31429</code>key words.<code>
    "dake-tech.posts.$title_text_content.brief_text_content.extended_text" :
    31429</code
  >Compare before just title only <code>1464</code> was indexed. Now, I'd like
  to run the same text search query again, it's the fun time!!
</p>
<pre class="language-javascript"><code>

<h3>How does Mongodb define score for text search?</h3>
<p>
  I don't have an answer for this yet, this is something I want to figure out.
  In the mean time, once your text search is enable, you can try something as
  following. You can also find document from MongoDB at
  <a
    href="https://docs.mongodb.org/manual/reference/operator/query/text/#text-operator-text-score"
    >Here</a
  >.
</p>
<ol>
  <li>
    search word
    <code> db.post.find( { $text: { $search: "javascript" } } ) </code>
  </li>
  <li>
    search phrase
    <code>
      db.post.find( { $text: { $search: "javascript angular react" } } )
    </code>
  </li>
  <li>
    Exclude Documents that contains term, following will search javascript and
    exclude angular from the document
    <code> db.post.find( { $text: { $search: "javascript -angular" } } ) </code>
  </li>
  <li>
    You can search for different language
    <code>
      db.post.find( { $text: { $search: "javascript", $language: "es" } } )
    </code>
  </li>
  <li>
    You can search Case Sensitive
    <code>

    </code>
  </li>
  <li>
    Case Sensitive for Phrase
    <code>
      db.post.find( { $text: { $search: "\"Javascript React\"", $caseSensitive:
      true } } )
    </code>
  </li>
  <li>
    Case Sensitive with exclude term, search Javascript but exclude lower-case
    javascript
    <code>
      db.post.find( { $text: { $search: "Javascript -javascript",
      $caseSensitive: true } } )
    </code>
  </li>
  <li>Diacritic Sensitive Search for a Term</li>
  <li>Diacritic Sensitivity with Negated Term</li>
  <li>
    Return the Text Search Score
    <code>
      db.posts.find( { $text: { $search: "javascript" } }, { score: { $meta:
      "textScore" }} )
    </code>
  </li>

<h2>Compilers</h2>
<p>
  It is confusing but .NET development has few different .NET compile exist, the
  compiler is,<code>csc.exe</code> but there's few different version. There are
  followings.
</p>
<ul>
  <li>.NET Framework's <code>csc.exe</code></li>
  <ul>
    <li>
      For example, .NET 4.6 located here.
      <code>C:\Windows\Microsoft.NET\Framework64\v4.0.30319\csc.exe</code>
    </li>
  </ul>
  <li>Visual Studio <code>csc.exe</code></li>
  <ul>
    <li>
      Visual Studio 2013 located here.
      <code>C:\Program Files (x86)\MSBuild\12.0\Bin\csc.exe</code>
    </li>
    <li>
      Visual Studio 2015 located here.&nbsp;<code
        >C:\Program Files (x86)\MSBuild\14.0\Bin\csc.exe</code
      >
    </li>
  </ul>
  <li>Roslyn's <code>csc.exe (example below use 1.0.0)</code></li>
  <ul>
    <li>
      Roslyn inside application bin folder, for example,
      <code>/bin/roslyn/csc.exe</code>
    </li>
  </ul>
</ul>
<p>
  So I think that's all the compiler in a different place so far and
  unfortunately, the version of the CSC<span style="font-family: monospace"
    >.EXE</span
  >&nbsp;are different. If they're all the same version I don't think I will see
  the error compiler C# 6 using C# 5 compiler.
</p>
<p>In summary, following are the different version when I checked it out.</p>
<ul>
  <li>.NET Framework's csc.exe - version 4.7.2556.0</li>
  <li>Visual Studio 2013 - version 12.0.21005.1</li>
  <li>Visual Studio 2015 - 1.3.1.60616</li>
  <li>Roslyn (1.0.0) - 1.0.0.50618</li>
</ul>

  That's why when I build the solution with Visual Studio 2015 is fine because
  it is using different csc.exe, but see error sometimes when deploying to local
  IIS or cloud. Also, ASP.NET MVC razor use a different compiler than C#, for
  example, if you have the code as following, target framework is 4.6 and you're
  not using Roslyn. This will also be built is fine, but when deploying to local
  you'll see compiler error.
</p>
<pre class="language-xml"><code>
@model WebApplication1.Models.MyModel
@if (string.IsNullOrWhiteSpace(Model.Test?.ToLower()))
{

}
</code>
</pre>
<h2>Roslyn</h2>
<p>
  Looks like things are moving to use&nbsp;<code>Roslyn</code>&nbsp;so make sure
  these two NuGet packages are available at your solution.
  <code>Microsoft.CodeDom.Providers.DotNetCompilerPlatform</code>,.<code
    >Microsoft.Net.Compilers. Also, make sure webconfig changes.</code
  >&nbsp;Roslyn should be able to decide what version is good for your
  solution.&nbsp;
</p>
<p>
  It should be simple just add following Nuget Package, but just make sure
  WebConfig is updated, sometimes&nbsp;I have the issue, WebConfig is updated on
  local but IIS site's WebConfig is not updated, so end up not using Roslyn but
  using .NET Framework's CSC.exe compiler.
</p>
<h3>NuGet packages</h3>
<ol>
  <li>Microsoft.CodeDom.Providers.DotNetCompilerPlatform</li>
  <li>Microsoft.Net.Compilers</li>

<h2>Phonegap icon and splash image generator</h2>
<p>
  So far, i don't think phonegap would generate icon and splash image for
  different device at iOS and android, also if modify for each device is quite
  works. You could use following links for generate icon and splash.
</p>
<p>
  You will need node.js if you want to use lonic or PhotoShop to edit the image
  a little bit.

Use Microsoft Stuff at Mac


<p>
  If you use Xamarin at windows and want to build app for Android and iOS, you
  could use iOS simulator at your windows. However there's few software and
  setting you might have to do. I assume you're having problem at windows
  Xamarin Mac Agent and unable to connect to your mac.
</p>
<p>
  <img
    class="img-responsive"
    src="https://d1p0mp3f1fx0hz.cloudfront.net/_0l7ux5l96.png"
    alt=""
  />
</p>
<p>First make sure your windows have following software installed.</p>
<ul>
  <li>Window PC</li>
  <ul>
    <li>Visual Studio 2015</li>
    <li>Xamarin for Visual Studio 2015</li>
  </ul>
  <li>Mac</li>
  <ul>
    <li>Enable Remote login</li>
    <li>
      Xamarin Studio (Xamarin Mac Agent need your Mac to have Mono installed)
    </li>
  </ul>
  <li>Others</li>
  <ul>
    <li>Make sure Mac and Window are at the same network.</li>
    <li>Still can't not connect to Mac, download PuTTY to test connection</li>
    <li>
      Or check here to see xamarin error, you might found useful message when
      you can't connect to Mac. C:\Users\{Your Windows User
      Account}\AppData\Local\Xamarin\Logs\14.0
    </li>
  </ul>
</ul>
<p style="padding-left: 30px">&nbsp;</p>


Xamarin - Can't Connect to Mac From Windows with Xamarin


<p>
  I had an issue that my app can't connect to my own api at the actual or
  emulator android device. Anyway, my issue is resolved by following change to
  root <code>config.xml</code>
</p>
<pre class="language-xml">
// change from this 
&lt;access origin="*" /&gt;
// to following code
&lt;access origin="http://*" /&gt;
&lt;access origin="https://*" /&gt;
</pre>
<p>
  Now, each dev's enviromen might be different, you might encouter the same
  issue by fixed by different things. At the point I was fixing my issue, my
  phonegap is using <code>6.4.2</code>, npm is <code>3.10.3</code>, node version
  is <code>v6.7.0</code>, Android studio is using <code>2.2.2</code>, windows OS
  version is <code>10.0.14393</code>.
</p>
<pre class="language-xml">
&gt; node -v
&gt; npm -v
&gt; ver
&gt; phonegap version
</pre>
<p>
  Some people also said they had same issue but because of missing
  <code>cordova-plugin-whitelist</code> plugin, but my phonegap <code></code> is
  already contains that plugin, but if you don't have it, you can try to add it
  to see if fix your issue or not.
</p>
<pre class="language-xml">
  &lt;plugin name="cordova-plugin-whitelist" source="npm" spec="~1.2.1" /&gt;
</pre>
<p>
  I also, my issue was html's content-security-policy issue, so I defined my api
  over there, so make sure all my api are able to call but at the end, still
  failed at the android device, and after I add my temporary access origin at
  the root <code>config.xml</code>, even I removed my content-security-policy
  tag, still works.
</p>
<pre class="language-xml">
&lt;meta http-equiv="Content-Security-Policy" content="default-src 'self' .....
</pre>
<p>So, could be phonegap change something away to handler these...</p>


Phonegap can't Access My Own Api Service


<p>
  So, Git, TFVC, and SVN, actually there is most source controls exist today,
  like Helix VCS, Mercurial, Rational ClearCase, CVS, Kiln, Bazaar, Fossil,
  Monotone, Plastic SCM, AWS CodeCommit and more. Some of them will disappear...
</p>
<p>

    alt="Image result for disappear funny image"
  />
</p>
<p>
  I only list <strong>Git</strong>, <strong>TFVC</strong>,
  <strong>SVN</strong> because I've been used these around for awhile, they're
  all popular.
</p>

    target="_blank"

<p>
  &nbsp;Based on what I have seen so far, I think it's better to just use Git
  instead.

<h3>robots.txt</h3>
<p>
  Easiest improvement for robots is add file robots.txt and following content.
  It means allow any robots engine to crawl your site, and don't index your
  /keystone and /admin root folder. One of the reason you do that is then these
  engine won't check your page so first your page speed is better.
</p>
<pre class="language-javascript"><code>User-agent: *
Disallow: /keystone
Disallow: /admin

More information about robots, see Create robots.txt file or robots database
</code></pre>
<h3>sitemap.xml</h3>
<p>
  sitemap.xml is another important thing to improve google crawl your website,
  I'm using following to auto generate sitemap.&nbsp;<a

  So I want to compile bootstrap sass, I searched online of<a
    href="http://getbootstrap.com/getting-started/"
    target="_blank"
  >
    Bootstrap website</a
  >. It contains bootstrap supports SASS but it doesn't contain detail of how to
  compile the SASS. That's make sense at the bootstrap site because there are so
  many tools could compile sass into css. I know the visual studio 2015's
  compiler plugin is very easy to let you compile bootstrap sass into css. But
  I'm in visual studio, first since I like use npm, node.js package management
  system. So I wonder npm must contains some sass compiler. So I found
  following, this could work but require grunt file setup and also need ruby,
  compass.&nbsp;
</p>
<p>That's a lot of work...</p>
<pre><code>grunt-contrib-sass
</code></pre>
<p>So, what I end up with...</p>
<h2>WebEssentials</h2>
<p>
  WebEssentials is a web tools for visual studio, first I run nuget to get SASS
  version of bootstrap.
</p>
<p><img src="https://d1p0mp3f1fx0hz.cloudfront.net/_5u3gicubz.png" alt="" /></p>
<p>
  Then I just create another file as bootstrap.scss and copied the code from
  _bootstrap.scss to mine bootstrap.scss.
</p>
<p>
  Save, then that's cause WebEssentials to compile the scss to css for me,
  sweet!
</p>
<p><img src="https://d1p0mp3f1fx0hz.cloudfront.net/_l271mtigm.png" alt="" /></p>
<p>
  Now, you can start change the variable inside the bootstrap scss to use the
  real power of bootstrap.
</p>
