I am about to start a Java project just for practice. I&#39;ve read about Maven, but I don&#39;t actually understand when it is meant to be used. 

Can you give me some practical tips? Does Maven help a lot? What does Maven actually do for my project?

I want something like

    0x2022	8226	BULLET	•

But bigger.

I can&#39;t even seem to find them at http://www.ssec.wisc.edu/~tomw/java/unicode.html

What should I search for? Dots? bullets?

What would be the Unicode character for big bullet in the middle of the character?

I was testing some HTML code I&#39;m making, and while using the Developer Tools on Google Chrome version 22.0.1229.94 m, I saw the `&lt;body&gt;` tag has the attribute `cz-shortcut-listen=&quot;true&quot;` (which of course is not on my code). **What does it mean and why is it showing up?** (I tried looking it up in google, but found nothing relevant)

I have found [articles][1] regarding cache behaviour so I can only assume that it&#39;s not much different but I wanted to make sure.

I have read that most browser have 5MB (give or take) for localStorage and I was interested in what would be the behaviour of the browsers?

I understand every browser acts differently but I&#39;m interested mostly in Safari, Chrome and Firefox (as those are the ones I consider as browsers).

 - Will the browsers mentioned above delete data from my website or it will choose &quot;the oldest&quot; or something of the sort?
 - Will my item be saved in such case?

**And the most important :**

 - Lets say I &quot;abuse&quot; the localStorage on my website trying to use it all up, and in the same page I&#39;m filling it up and trying to save more. Will I get a warning? Will the `getItem` return `null` when this happens or is it somehow saved in memory?

 - What happens if I try and save an item larger than the `localStorage` size?

 **Answered:**  answer can be found [here][2]

 - Can the same exact behaviour be expected from sessionStorage which allegedly should be the same?

I know this is a lot of questions but I&#39;m trying to understand all that&#39;s related to the subject, I&#39;d be thankful for any part of the question you can answer.

&gt; Duplicate headers received from server
&gt;
&gt; The response from the server contained duplicate headers. This problem is generally the result of a misconfigured website or proxy. Only the website or proxy administrator can fix this issue.
&gt;
&gt; Error 349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION): Multiple distinct Content-Disposition headers received. This is disallowed to protect against HTTP response splitting attacks.

 I found this error while exporting to pdf in chrome.

    Response.Buffer = false;
    Response.ClearHeaders();
    string ext = objProp.PACKAGEFILENAME.Substring(objProp.PACKAGEFILENAME.LastIndexOf(&quot;.&quot;));
    string ext1 = ext.Substring(1);
    Response.ContentType = ext1;
    Response.AddHeader(&quot;Content-Disposition&quot;, &quot;target;_blank,attachment; filename=&quot; + objProp.PACKAGEFILENAME);
    const int ChunkSize = 1024;
    byte[] binary = objProp.PACKAGEDOCUMENT;
    System.IO.MemoryStream ms = new System.IO.MemoryStream(binary);
    int SizeToWrite = ChunkSize;

    for (int i = 0; i &lt; binary.GetUpperBound(0) - 1; i = i + ChunkSize)
    {
        if (!Response.IsClientConnected) return;
        if (i + ChunkSize &gt;= binary.Length) SizeToWrite = binary.Length - i;
        byte[] chunk = new byte[SizeToWrite];
        ms.Read(chunk, 0, SizeToWrite);
        Response.BinaryWrite(chunk);
        Response.Flush();
    }
    Response.Close();

I am making a HTML page and one of the things I wanted was a favicon appearing next to the title.

I&#39;m using Google Chrome, I see favicons working on other websites, but the favicon on my website won&#39;t show up.  The site is in a folder on my desktop named site.

The `favicon.ico` file is 16x16, and I used an online generator to make it.

This is the code: 

    &lt;!DOCTYPE html&gt;
    &lt;html&gt; 
        &lt;head&gt;
            &lt;title&gt;&lt;/title&gt;
            &lt;link rel=&quot;shortcut icon&quot; href=&quot;/favicon.ico&quot; /&gt;
        &lt;/head&gt;
        &lt;body&gt;
        &lt;/body&gt;
    &lt;/html&gt;

 

HTML Favicon.ico won&#39;t show on Google Chrome

I have a loop that creates 20 ***check-boxes*** in the same page (it creates different forms). I want via ***chrome developer tools*** to run a JavaScript without the use of any library that ***CHECK*** all *check-boxes* at the same time.

This is as far as I got:
------------------------


    function() {
    	var aa= document.getElementsByTagName(&quot;input&quot;);
    	for (var i =0; i &lt; aa.length; i++){
    	 aa.elements[i].checked = checked;
    	}
    }

PS: I have searched and found a lot of Questions in Stack-Overflow but none worked for me, I&#39;ll be glad if someone could find me the correct answer.
