If you mean jumping back and forward through the cursor position history, then in Sublime Text 3 it&#39;s [built in][1] via the GoTo menu or keyboard shortcuts:

&gt; Jump Back and Jump Forward – Jump Back allows you to go to previous
&gt; editing positions. This goes hand in hand with Goto Definition: you
&gt; can now inspect a symbol definition, and quickly jump back to where
&gt; you were previously. Jump Back is bound to **Alt+Minus** by default.
&gt; The menu entry is Goto &gt; Jump Back


There are plugins available for ST2, for example [navigationHistory][2].

I am trying to build a neural network from scratch.
Across all AI literature there is a consensus that weights should be initialized to random numbers in order for the network to converge faster.

**But why are neural networks initial weights initialized as random numbers?** 

I had read somewhere that this is done to &quot;break the symmetry&quot; and this makes the neural network learn faster. How does breaking the symmetry make it learn faster?

Wouldn&#39;t initializing the weights to 0 be a better idea? That way the weights would be able to find their values (whether positive or negative) faster?

Is there some other underlying philosophy behind randomizing the weights apart from hoping that they would be near their optimum values when initialized?

Why should weights of Neural Networks be initialized to random numbers?

**[Enable intellisense on HTMLHelper attribute for css classes]**

I have this HTMLhelper:

    public IHtmlString MyTextBoxFor&lt;TModel, TProperty&gt;(
        this HtmlHelper&lt;TModel&gt; html, 
        Expression&lt;Func&lt;TModel, TProperty&gt;&gt; propertyExpression, 
        string cssClass)
    {
        // ...
    }

I want Resharper to give me IntelliSense for CSS classes defined in my application when passing the value for the &quot;cssClass&quot; parameter.

There are some code annotation attributes that Resharper recognizes, but none that seem directly related to marking a method parameter as being CSS classes.

The closest I could find was **[HtmlAttributeValue(string name)]**.
I tried to apply to the cssClass parameter like this:

    public IHtmlString MyTextBoxFor&lt;TModel, TProperty&gt;(
        this HtmlHelper&lt;TModel&gt; html, 
        Expression&lt;Func&lt;TModel, TProperty&gt;&gt; propertyExpression, 
        [HtmlAttributeValue(&quot;class&quot;)] string cssClass)
    {
        // ...
    }

But that doesn&#39;t work. It would also be super awesome if Resharper would recognize the entered class and stop bugging me about unknown CSS classes in jQuery selector expressions (that operate on the textbox generated by the helper above).

**Edit:**
Here&#39;s a screenshot of the kind of intellisense that is working for the &quot;htmlAttributes&quot; parameter of an action method. This is accomplished by using the [HtmlElementAttributes] annotation on the parameter.

[![Resharper htmlAttributes intellisense][1]][1]

I want a similar annotation that lets me put css classes in a string parameter and have the same intellisense appear showing css classes.

How do you tell Resharper that a method parameter is a string containing a CSS class?

How to jump back and forward through the cursor position history in Sublime Text?

I google a lot and find [BufferScroll][1]. But it doesn&#39;t work for me. I can&#39;t find any shortcut or how to use it in the document.

Update:

Every time I try to use Jump Forward (&lt;kbd&gt;SHIFT&lt;/kbd&gt;+&lt;kbd&gt;ALT&lt;/kbd&gt;+&lt;kbd&gt;-&lt;/kbd&gt;), my editor always says &quot;Already at the newest position&quot; while actually not in the newest position. Jump Back (&lt;kbd&gt;ALT&lt;/kbd&gt;+&lt;kbd&gt;-&lt;/kbd&gt;) works well.

I know this has been asked a thousand time but I can&#39;t find a way to make the text and image to be centered vertically.

I&#39;m using Twitter Bootstrap 3 with dynamic content so therefor, I do not know the size on neither the text nor the image. Plus, I want it all to be responsive.

I&#39;ve created a [bootply](http://bootply.com/94381) that summarize the kind of layout I&#39;m trying to achieve. Basically, I want the text and image to be vertically centered. The text is not always bigger than the image.

Can someone help me out with this please?

Thank you.

I have a PHP file that tries to echo a `$_POST` and I get an error, here is the code:

    echo &quot;&lt;html&gt;&quot;;
    echo &quot;&lt;body&gt;&quot;;
    for($i=0; $i&lt;5;$i++){
        echo &quot;&lt;input name=&#39;C[]&#39; value=&#39;$Texting[$i]&#39; &quot; .

    }
    echo &quot;&lt;/body&gt;&quot;;
    echo &quot;&lt;/html&gt;&quot;;
    echo &#39;&lt;input type=&quot;submit&quot; value=&quot;Save The Table&quot; name=&quot;G&quot;&gt;&lt;/input&gt;&#39;


Here is the code to echo the POST.

    if(!empty($_POST[&#39;G&#39;])){
        echo $_POST[&#39;C&#39;];

But when the code runs I get an error like:

I know this this has been asked in numerous posts but honestly I don&#39;t get them. I am new to JavaScript, Chrome Extensions and everything and I have this class assignment.
So I need to make a plugin that would count DOM objects on any given page using Cross Domain Requests. 
I&#39;ve been able to achieve this so far using Chrome Extension API&#39;s. 
Now the problem is I need to show the data on my popup.html page from the contentScript.js file. 
I don&#39;t know how to do that I&#39;ve tried reading the documentation but messaging in chrome I just can&#39;t understand what to do. 

following is the code so far.

Github announced [Atom](https://atom.io/) which is very similar to Sublime. Even some keyboard shortcuts like &lt;kbd&gt;⌘ + P&lt;/kbd&gt;, &lt;kbd&gt;⌘ + Shift + P&lt;/kbd&gt; etc. are same.  

1. How is Atom different from Sublime?  
2. Does it include IDE features like build tools, function definition jumps, documentations, etc.?
3. Has anyone using Sublime got a Beta invitation to point out the differences?
4. Can I use the themes, schemes and packages from Sublime as is, like Sublime could do with **text mate**.
