How can I switch between using one class or another in AngularJS?

How can I switch between using one class or another in AngularJS?

I have the following code:
<i style="margin-right: 0.5em; color: #EEEEEE;" class="icon-home
icon-4x"></i>
I would like to change the color of the SVG icon depending on if my
ui-router state as follows:
If the state includes 'admin' I would like it to use the class red-icon
If the state does not include 'admin' I would like it to use the class
blue-icon
I have done something like this before:
data-ng-class="{ current: $state.includes('admin') }"
But how can I make it switch between the two colors?

Tinymce url needs to be versatile

Does move semantic unsuitable to the array in C++11?

Does move semantic unsuitable to the array in C++11?

I test the unique_ptr<> as follow
#include <iostream>
#include <memory>
using namespace std;
class A
{
public:
virtual ~A() {}
virtual void print()
{
cout << "A::Print()" << endl;
}
};
class B : public A
{
public:
virtual ~B() {}
virtual void print()
{
cout << "B::Print()" << endl;
}
};
int main()
{
A a;
B b;
A* arr[2] = {&a, &b};
arr[0]->print();
arr[1]->print();
unique_ptr<A*[]> ptr(move(arr));
/*
unique_ptr<A*[]> ptr(new A*[2]{&a, &b});
*/
ptr[0]->print();
ptr[1]->print();
return 0;
}
It get the result like (g++ 4.7.3)
A::Print()
B::Print()
A::Print()
B::Print()
Aborted (core dumped)
It seem like the ptr and arr point to the samething and when call
destructor, it has been deleted twice.
Why the move semantic don't take effect here?
Does it unsuitable to the array or it is about the unique_ptr?

Custom String representation of an Object in Java

Is there any way to change how an object represents itself as a String?
For example, having System.out.println(new JLabel()); output Empty JLabel.

jquery - gridster, still linking on page even after drag

jquery - gridster, still linking on page even after drag

so my problem is next. Im using gridster.js and after long researching of
stackoverlow i found a numerous similar solutions for this problem, but
again, i couldnt implement that on my issue. So the issue here is that i
want to link an ID to web-page, but only when i fully click on that box
inside of gridster. Issue is, when i move the very same box, and do a
mouseover, i still get linked on that page. Difference here is that im not
using any tags like previous guys did in their posts, so im basically
trying to link it over simple ID.
http://jsfiddle.net/tr4cU/23/`">FIDDLE LINK
also there is code here:
var gridster;
$(function() {
gridtster = $(".gridster > ul").gridster({
widget_margins: [10, 10],
widget_base_dimensions: [140, 140],
min_cols: 6
}).data('gridster');
$('#contacts').click(function () {
window.location = $(this).attr("url");
});
});

How to target individually nested elements using CSS

How to target individually nested elements using CSS

I'm trying to target each span individually in a structure like below.
I've tried nth-child() & nth-of-type() but I've have no luck, it was only
applying the first style to all of the spans. Anyone no know how to do
this without giving each a separate IDs?
<div>
<div>
<span></span>
</div>
<div>
<span></span>
</div>
<div>
<span></span>
