Original Values changes are not reflecting in reference types varaiable in C#

Original Values changes are not reflecting in reference types varaiable in C#

please help on this
object a = "1411";
object b = a;
Console.WriteLine("Before Value of a " + a);
Console.WriteLine("Before Value of b " + b);
a = "5555";
Console.WriteLine("After Value of a " + a);
Console.WriteLine("After Value of b " + b);
Console.ReadKey();
output :
Before Value of a 1411
Before Value of b 1411
After Value of a 5555
After Value of b 1411
After Value of b also should changed to 5555 right ? since b is reference
types varaiable.

SPARQL Calculating the difference between two date

SPARQL Calculating the difference between two date

What is the function to calculate difference between two SPARQL
xsd:dateTime ?
I have found a reference to datediff, but this is not working. Does such a
built in function exist in SPARQL as it does with most other query
languages?

Google crawl error with HTTP_ACCEPT_LANGUAGE

Google crawl error with HTTP_ACCEPT_LANGUAGE

in my codeigniter app I use $_SERVER['HTTP_ACCEPT_LANGUAGE'] to determine
the users browser language to set the app language based on that, like
that:
public function __construct()
{
parent::__construct();
/* set session language if not set. "hu" if browser language "hu", else
"en" */
if(!($this->session->userdata("lang")))
{
$browserlang = substr($_SERVER["HTTP_ACCEPT_LANGUAGE"],0,2);
if ($browserlang == "hu")
{
$this->config->set_item("language", "hu");
$this->session->set_userdata("lang", "hu");
$this->lang->load("bh_hu", "hungarian");
}
else
{
$this->config->set_item("language", "en");
$this->session->set_userdata("lang", "en");
$this->lang->load("bh_en", "english");
}
}
else
{
switch ($this->session->userdata("lang"))
{
case "hu": $this->lang->load("bh_hu", "hungarian"); break;
case "en": $this->lang->load("bh_en", "english"); break;
}
}
....
}
Everything's working fine, but as the google crawler does not send any
HTTP_ACCEPT_LANGUAGE, it returns a php error Undefined index:
HTTP_ACCEPT_LANGUAGE when crawling all my pages. This is really nasty,
because the php error even fills up my entire google search snippet. Is
there a way to just let the google bot ignore the HTTP_ACCEPT_LANGUAGE
action? Thanks in advance!

Getting auto margin to work for center aligning div

Getting auto margin to work for center aligning div

I've overlooked something obvious and simple for sure here but I'm going
to have to admit defeat and ask on SO for now.
I've made a JSfiddle.
A simple one. Simply trying to center align the div class ratings inside
it's parent container. I haven't managed to get any auto margins to work
at all after numerous faffing with it.
The code below:-
CSS
.caption {
padding: 9px;
width: 100%;
display: block;
}
.ratings {
width: 100%;
overflow: hidden;
margin: 3px auto;
display: block;
}
Markup
<div class="caption">
<h2 class="product-name"><a href="#">Product Title</a></h2>
<div class="ratings">
<div class="rating-bar">
<div class="rating-box"></div>
<div class="rating" style="width:100%"></div>
<div class="rating-fill"></div>
</div>
<span class="amount"><a href="#">(2)</a></span>
</div>
</div>
