For example: border-radius is not supported in Yahoo! Mail, Outlook 2007/10/13 +, Outlook 03/Express/Mail & Android 4 (Gmail) +
To work around this we can add images with border radius in them i.e...

Reference types are comprised of both a reference to a memory area, and a value stored within that area.
This is analogous to pointers in C/C++.
All reference types are stored on what is known as the heap.
The heap is simply a managed area of memory where objects are stored. When a new object is ...
To use the example above on a blade template to hide content from the user, you would typically do something like this:
@can('view-content', $content)
<! -- content here -->
@endcan
To completely prevent navigation to the content, you can do the following in your controller:
if(Gate::a...
Policies are classes that help you organise authorisation logic around a model resource. Using our previous example, we might have a ContentPolicy that manages user access to the Content model.
To make ContentPolicy, laravel provides an artisan command. Simply run
php artisan make:policy ContentPo...
Writing Policies follows much the same pattern as writing Gates. The content permission gate can be rewritten as a Policy like this:
function view($user, $content)
{
return $user->isSubscribedTo($content->id);
}
Policies can contain more methods as needed to take care of all authori...
Via The User model
The Laravel User model contains two methods that help with authorisations using Policies; can and can't. These two can be used to determine if a user has authorisation or not on a model respectively.
To check if a user can view a content or not, you can do the following:

The Problem
You have a set of things to do (activities). Each activity has a start time and a end time. You aren't allowed to perform more than one activity at a time. Your task is to find a way to perform the maximum number of activities.
For example, suppose you have a selection of classes to ch...

In the following, weight is declared as a mutable field.
type person = {
name: string;
mutable weight: int
};;
