Laravel automatically resolves Eloquent models defined in routes or controller actions whose variable names match a route segment name. For example: Route::get('api/users/{user}', function (App\User $user) { return $user->email; }); In this example, since the Eloquent $user variable de...

To register an explicit binding, use the router's model method to specify the class for a given parameter. You should define your explicit model bindings in the boot method of the RouteServiceProvider class public function boot() { parent::boot(); Route::model('user', App\User::class); ...

The standard library comes with a rich collection of lazy iterables (and libraries such as Iterators.jl provide even more). Lazy iterables can be composed to create more powerful iterables in constant time. The most important lazy iterables are take and drop, from which many other functions can be c...

Although it might not be proper to do such thing in a view if you intend to separate concerns strictly, the php Blade directive allows a way to execute PHP code, for instance, to set a variable: @php($varName = 'Enter content ') (same as:) @php $varName = 'Enter content '; @endphp late...

Each control has a property DataBindings which is a list of System.Windows.Forms.Binding objects. The Add()-method has some overloads which enables you easily binding to the property of an object: textBox.DataBindings.Add( "Text", dataObj, "MyProperty" ); Note, that binding b...

The BigInteger class has a constructor dedicated to generate random BigIntegers, given an instance of java.util.Random and an int that specifies how many bits will the BigInteger have. Its usage is quite simple - when you call the constructor BigInteger(int, Random) like this: BigInteger randomBigI...

Rabin-Karp Algorithm is a string searching algorithm created by Richard M. Karp and Michael O. Rabin that uses hashing to find any one of a set of pattern strings in a text. A substring of a string is another string that occurs in. For example, ver is a substring of stackoverflow. Not to be confuse...

For Searching a place, we use the powerful element that Polymer ships, called google-map-search . All you need to do, is pass a map object and a query string to the element like so: <google-map-search map=[[map]] query=[[query]]></google-map-search> How do we pass the map ob...

The Rabin–Karp algorithm or Karp–Rabin algorithm is a string searching algorithm that uses hashing to find any one of a set of pattern strings in a text.Its average and best case running time is O(n+m) in space O(p), but its worst-case time is O(nm) where n is the length of the text and m is the le...

Due to way that the float type is represented in computer memory, results of operations using this type can be inaccurate - some values are stored as approximations. Good examples of this are monetary calculations. If high precision is necessary, other types should be used. e.g. Java 7 provides Big...

The whole point of MVVM is to separate layers containing logic from the view layer. On Android we can use the DataBinding Library to help us with this and make most of our logic Unit-testable without worrying about Android dependencies. In this example I'll show the central components for a stupid...
