In a web application, typically they are used to generate the HTML output that is sent back to users with each response. By default, views in Laravel are stored in the resources/views directory. A view can be called u...

Implementations in classes, including abstract declarations, take precedence over all interface defaults. Abstract class method takes precedence over Interface Default Method. public interface Swim { default void backStroke() { System.out.println("Swim.backStroke"); ...

$string = "0| PHP 1| CSS 2| HTML 3| AJAX 4| JSON"; //[0-9]: Any single character in the range 0 to 9 // + : One or more of 0 to 9 $array = preg_split("/[0-9]+\|/", $string, -1, PREG_SPLIT_NO_EMPTY); //Or // [] : Character class // \d : Any digit // + : One or more ...

For instance, a computation involving commands to read and write from the prompt: First we describe the "commands" of our computation as a Functor data type {-# LANGUAGE DeriveFunctor #-} data TeletypeF next = PrintLine String next | ReadLine (String -> next) derivin...

There are two parts of a class: the interface and the implementation. The interface is the exposed functionality of the class. Its public methods and variables are part of the interface. The implementation is the internal workings of a class. Other classes shouldn't need to know about the implemen...

When implementing more than one interface that have methods of the same name that include default implementations, it is ambiguous to the compiler which implementation should be used. In the case of a conflict, the developer must override the conflicting method and provide a custom implementation. ...

A query engine is required in order to execute SPARQL queries over a dataset. Query engines may be embedded in applications, or accessed remotely. Remote access may be through a vendor-specific API, or through the SPARQL protocol if an implementation supports it. This documentation will not cover ho...

In the Web App blade of the Azure Portal, click All settings > WebJobs to show the WebJobs blade: Click Add. The Add WebJob dialog appears. Under Name, provide a name for the WebJob. The name must start with a letter or a number and cannot contain any special characters other than...

EXPOSE <port> [<port>...] From Docker's documentation: The EXPOSE instruction informs Docker that the container listens on the specified network ports at runtime. EXPOSE does not make the ports of the container accessible to the host. To do that, you must use either the -p flag to ...

9.0 // Since the anchor system simply returns constraints, you still need to add them somewhere. View.AddConstraints( new[] { someLabel.TopAnchor.ConstraintEqualTo(TopLayoutGuide.GetBottomAnchor()), anotherLabel.TopAnchor.ConstraintEqualTo(someLabel.BottomAnchor, 6), ...

// Using Visual Format Language requires a special look-up dictionary of names<->views. var views = new NSDictionary( nameof(someLabel), someLabel, nameof(anotherLabel), anotherLabel, nameof(oneMoreLabel), oneMoreLabel ); // It can also take a look-up dictionary for metrics (...

It is possible to mount a host directory to a specific path in your container using the -v or --volume command line option. The following example will mount /etc on the host to /mnt/etc in the container: (on linux) docker run -v "/etc:/mnt/etc" alpine cat /mnt/etc/passwd (on windows) do...

Since C++14, the standard provides the class template template <class T, T... Ints> class integer_sequence; template <std::size_t... Ints> using index_sequence = std::integer_sequence<std::size_t, Ints...>; and a generating metafunction for it: template <class T, T N&g...

The array_intersect function will return an array of values that exist in all arrays that were passed to this function. $array_one = ['one', 'two', 'three']; $array_two = ['two', 'three', 'four']; $array_three = ['two', 'three']; $intersect = array_intersect($array_one, $array_two, $array_thre...

git difftool -t meld --dir-diff will show the working directory changes. Alternatively, git difftool -t meld --dir-diff [COMMIT_A] [COMMIT_B] will show the differences between 2 specific commits.

Suppose you have a Dockerfile ending with ENTRYPOINT [ "nethogs"] CMD ["wlan0"] if you build this image with a docker built -t inspector . launch the image built with such a Dockerfile with a command such as docker run -it --net=host --rm inspector ,nethogs will monitor the...

Floating point numbers of type real cannot have any real value. They can represent real numbers up to certain amount of decimal digits. FORTRAN 77 guaranteed two floating point types and more recent standards guarantee at least two real types. Real variables may be declared as real x double prec...

All these are shell commands If you need to log onto a running docker-machine directly, you can do that: docker-machine ssh to ssh into the default docker-machine docker-machine ssh machinename to ssh into a non-default docker-machine If you just want to run a single command, you can do so...

You can make an UILabel with a dynamic height using auto layout. You need to set the numberOfLines to zero (0), and add a minimal height by setting up a constraints with a relation of type .GreaterThanOrEqual on the .Height attribute iOS 6 Swift label.numberOfLines = 0 let heightConstraint = ...

Assembly language is a human readable form of machine language or machine code which is the actual sequence of bits and bytes on which the processor logic operates. It is generally easier for humans to read and program in mnemonics than binary, octal or hex, so humans typically write code in assemb...
