I have a new computer and installed Linux Mint. When I tried to install npm and then install the angular cli it won't let me, I get this error:

simon@simon:~$ sudo apt-get update
[sudo] password for simon:
E: Malformed line 2 in source list /etc/apt/sources.list.d/i2p-maintainers-i2p-bionic.list (type)
E: The list of sources could not be read.

While searching on stackoverflow in english, some answers commented to edit the file sources.listor create a new one, but it doesn't work, it doesn't give me permission neither to edit or change it.

TO UPDATE

Given the comments of several about the source.list file, I get this:

  GNU nano 2.9.3                                                            sources.list

Any possible solution?

While reading a PHP article, I saw the type of string php double quotedand was curious to know how it works while reading their English documentation on PHP.

font

I didn't find much information about it, String double quotedis it just a Stringsimple and ordinary one or does it have any special or additional functionality?

While reading this W3C document , I came across a part that made me curious:

Similarly, just as natural languages ​​have grammatical rules for how different words can be used, HTML has rules for where and how each element and attribute can be used.

Which can be translated as:

Similarly, just as natural languages ​​have grammatical rules for how different words can be used, HTML has rules for where and how each element and attribute can be used.

Logically I understand that HTML is not like languages ​​like JavaScript or Java. So my question is:

Does HTML have a mathematical logic to position the elements in a logical (mathematical) way and order so that the document makes current sense? Or is it just a hierarchical order of the DOM? (because I believe that the text refers to the logical plot that a web page has in the DOM)

Could someone expert in HTML5 explain it to me?

I have the following code and I try to add a down effect to the dropdown so that when it is clicked it slides down slowly.

 <li class="nav-item dropdown">
        <a   class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
          Dropdown
        </a>
        <div class="dropdown-menu" aria-labelledby="navbarDropdown">
          <a class="dropdown-item" href="#">Action</a>
          <a class="dropdown-item" href="#">Another action</a>
          <div class="dropdown-divider"></div>
          <a class="dropdown-item" href="#">Something else here</a>
        </div>
      </li>

The code I have tried to use is the following:

  $('.dropdown').on('show.bs.dropdown', function() {
    $(this).find('.dropdown-menu').first().stop(true, true).slideDown();
  });
  $('.dropdown').on('hide.bs.dropdown', function() {
    $(this).find('.dropdown-menu').first().stop(true, true).slideUp();
  });

As you can see the code I simply apply a show animation to the hide to show and hide my dropdown but it doesn't work does anyone have any idea how to solve this type of problem?

Also try applying the following code:

  <script type="text/javascript">
      $( document.body ).click(function () {
  if ( $( "div:dropdown-menu" ).is( ":hidden" ) ) {
    $( ".dropdown-menu" ).slideDown( "slow" );
  } else {
    $( ".dropdown-menu" ).hide();
  }
});
</script>

NOTE: I added all bootstrap and jquery links.

I'm new to c# and I have the following code:

 using System;

public class Program
{
    public static void Main()

    {

        int precio;
        int cantidadarticulo;
        int subtotal;
        int siniva;
        int coniva;
        int total;

     Console.WriteLine("dame nombre : ");
     string nombrepedido = Console.ReadLine();

     Console.WriteLine("dame precio : ");
     string preciopedidos = Console.ReadLine();
     precio = Convert.ToInt32(preciopedidos);


     Console.WriteLine("dame cantidad de cualquier articulo : ");
     string cantidadarticulopedido = Console.ReadLine();
     cantidadarticulo = Convert.ToDouble(cantidadarticulopedido);


        //calcular subtotal
        subtotal = cantidadarticulo/16;

and if you see in this next line I'm using toDouble to convert a String to a double to get the subtotal.

 cantidadarticulo = Convert.ToDouble(cantidadarticulopedido);

For that I am using this c# code:

Convert.ToDouble Method (String)

source of the above code

this is the complete code:

using System;

public class Program
{
    public static void Main()

    {

        int precio;
        int cantidadarticulo;
        int subtotal;
        int siniva;
        int coniva;
        int total;

     Console.WriteLine("dame nombre : ");
     string nombrepedido = Console.ReadLine();

     Console.WriteLine("dame precio : ");
     string preciopedidos = Console.ReadLine();
     precio = Convert.ToInt32(preciopedidos);


     Console.WriteLine("dame cantidad de cualquier articulo : ");
     string cantidadarticulopedido = Console.ReadLine();
     cantidadarticulo = Convert.ToDouble(cantidadarticulopedido);


        //calcular subtotal
        subtotal = cantidadarticulo/16;




        Console.WriteLine("subtototal: ");
        Console.WriteLine("sin iva: ");
        Console.WriteLine("total: ");



    }
}

I do not understand why it does not work if in the documentation it indicates that I must use toDouble to convert a string to Double, where could my error be?

I have the following code from the java oracle documentation:

public class LocalClassExample {

    static String regularExpression = "[^0-9]";

    public static void validatePhoneNumber(
        String phoneNumber1, String phoneNumber2) {

        final int numberLength = 10;

        // Valid in JDK 8 and later:

        // int numberLength = 10;

        class PhoneNumber {

            String formattedPhoneNumber = null;

            PhoneNumber(String phoneNumber){
                // numberLength = 7;
                String currentNumber = phoneNumber.replaceAll(
                  regularExpression, "");
                if (currentNumber.length() == numberLength)
                    formattedPhoneNumber = currentNumber;
                else
                    formattedPhoneNumber = null;
            }

            public String getNumber() {
                return formattedPhoneNumber;
            }

            // Valid in JDK 8 and later:

// public void printOriginalNumbers() {
// System.out.println("Original numbers are " + phoneNumber1 +
// " and " + phoneNumber2);
// }
        }

        PhoneNumber myNumber1 = new PhoneNumber(phoneNumber1);
        PhoneNumber myNumber2 = new PhoneNumber(phoneNumber2);

        // Valid in JDK 8 and later:

// myNumber1.printOriginalNumbers();

        if (myNumber1.getNumber() == null)
            System.out.println("First number is invalid");
        else
            System.out.println("First number is " + myNumber1.getNumber());
        if (myNumber2.getNumber() == null)
            System.out.println("Second number is invalid");
        else
            System.out.println("Second number is " + myNumber2.getNumber());

    }

    public static void main(String... args) {
        validatePhoneNumber("123-456-7890", "456-7890");
    }
}

In this part of the official java documentation

Local classes are classes that are defined in a block, which is a group of zero or more statements between balanced braces. You typically find local classes defined in the body of a method.

I understand that a local class are classes defined in a block, etc., but I don't understand their purpose in general.

• What could you use them for?
• Are they similar to java anonymous classes or are they different?

npm ERR! Please include the following file with any support request:
npm ERR! /home/sommer/npm-debug.log

To update:

After the comment of a user who executed the command as administrator I got the following:

npm WARN deprecated [email protected]: Use uuid module instead
/usr/local/bin/cordova -> /usr/local/lib/node_modules/cordova/bin/cordova

That error will not cause me an error in the execution of the application?

i'm new to cordova

but if I install cordova correctly:

sommer@sommer-AO532h:~$ cordova --version
7.0.1
sommer@sommer-AO532h:~$

I'm looking at the topic of annotations in the Oracle documentation . And looking at this example:

@ClassPreamble (
   author = "John Doe",
   date = "3/17/2002",
   currentRevision = 6,
   lastModified = "4/12/2004",
   lastModifiedBy = "Jane Doe",
   // Note array notation
   reviewers = {"Alice", "Bob", "Cindy"}
)
public class Generation3List extends Generation2List {

// class code goes here

}

I still don't understand what it can do for me. For example, if I remove the annotation it still works; So what are they generally used for? They explained to me that they are used for interfaces but until then I understood.

Going over C, I was wondering:

What is the difference between macros and consts, if in general the purpose of each one is to create a value that never changes?

Example of using a const:

#include <stdio.h>

void main()
{
    const int height = 100; /*constante de tipo entera*/
    const float number = 3.14; /*constante de tipo real*/
    const char letter = 'A'; /*constante de tipo caracter*/
    const char letter_sequence[10] = "ABC"; /*constante de tipo cadena*/
    const char backslash_char = '\?'; /*contante de caracter especial*/
    printf("Valor de la altura :%d \n", height );
    printf("valor del número : %f \n", number );
    printf("valor de la letra : %c \n", letter );
    printf("Valor de la secuencia de letras : %s \n", letter_sequence);
    printf("Valor del caracter de barra invertida : %c \n", backslash_char);
}

Example of the use of macros:

#include<stdio.h>
#define PI 3.1416//Macro
int main(){
    int  x = 10:
    suma = PI + x;

    printf("la suma es %.2f",suma);

    return 0;
}

Hello friends, I have this following code that works correctly, but when I want to justify the text, everything is centered on itself and it is not placed on the left and right.

Is there any CSS property to be able to justify the text when it is on the right and left?

My code:

body,
html{
/*
	height:100%;
	width:100%;
	position:relative;
	background-image:url(https://rolandocaldas.com/wp-content/uploads/2013/05/css3.png),
	url(https://rolandocaldas.com/wp-content/uploads/2013/05/css3.png);
	background-repeat:no-repeat,no-repeat;
    background-position:top left , top right;
*/
}

.texto1{
	font-style:normal;
	/*HERMOSA PROPIEDAD CSS*/
	font-variant:small-caps;/*CAMBIA TODO A MAYUSCULA Y LE PONE UN ESTILO TIPO LIBRO*/
    /*font-weight:lighter;/*normal,bold,ligh,lighter,100-900*/
    font-size:100%;
    line-height:30px;/*Separa cada linea de texto  de la otra que sigue*/
    font-family:arial;
    text-align:right;



}

.texto2{

	font:italic small-caps 400 100%/30px arial;
	text-align:left;

Hello friends I have the following code I use the JQuery library and I need to slow down the animation of the writing of the animation I want it to look slow but not too slow, does anyone know how I could do that? or do you know a part of the Jquery docs to be able to do it?

Hello friends, I have the following project and everything works correctly, but when I get to the 2560x1440 dimension, as far as I can tell, it is the largest dimension of the Computer, consult this website for that: http://www.websitedimensions.com/ , but what I do not understand is it because the menu disappears, I thought it was a menu tag error but no, copy and paste the materialize css framework structure again, would anyone know why?

My code is this: (note I joined all the code so that you could see it completely, I have it separated in its specific files: the html5 with the html5 and the css in its css folder) I am new to this Framework.

Sticky Footer
A sticky footer always stays on the bottom of the page regardless of how little content is on the page. However, this footer will be pushed down if there is a lot of content, so it is different from a fixed footer. Add the following code to your CSS file.

Hello friend, I have a small PHP exercise in which I have to request the user's name and tell him how many words his full name has and that's it.

but I do not know it, I have this following code:

$requestedtext = print "var name= prompt('what's your name');";


echo "Your name has:";
echo str_word_count($textrequested);//will return the number of words in a string

Hello colleagues, I have the following code, the purpose of which depends on which button you give it, it shows you an image and the name of the character, the image shows it to me and its name, but in the first it works correctly but in the second it doesn't work for me because I The name of the first one continues to appear and also the one that corresponds to it.

The truth is that I was thinking of another function that would handle this problem, but it seems confusing to me, which would cause a paste code?

What do you think?

My Current Code:

<!DOCTYPE html>
<html>
<body>
<title>Mario Bros</title>
<script type="text/javascript">
	




 function red(){

 	document.getElementById('myImage').src='indice.jpeg';
     document.getElementById("mario").innerHTML = "Mario Bros";
 }

function verde(){
       document.getElementById('myImage').src='luchi.jpeg';
      document.getElementById("luchi").innerHTML = "Luchi";


}


</script>
<h1>Mario Bros</h1>



<img id="myImage" src="http://www.esucesos.com/wp-content/uploads/2015/09/mario-bros.-1.jpg" style="width:100px">


<p id="mario"></p>
<p id="luchi"></p>
<button onclick="red();">Mario</button>

<button onclick="verde();">Luchi</button>

</body>
</html>

I have a project in which I have to change the background of the terminal

I saw many examples but for windows and I hardly see them in GNU/linux it is in the system that I am at this moment.

Note: I always mention the function system(); but according to me that only works for windows and its terminal.

Hello friends, I am starting to see in node js and I get this error:

origin of the code with which I am using: http://fernando-gaitan.com.ar/introduccion-a-node-js-parte-3-crear-modulos/

img of the error:

Hello friends of unity3D, sorry, I'm a programmer but mainly java and PHP and I'm creating a small game of two soldiers that shoot something simple but I need the shooting effect to be seen when shooting, how could I do that in unity?

Note: I already saw your docs but I can't find it, someone could send me a link at least where it is

Excuse me, I'm new to Unity.

I have a little code in which the purpose is to check the username and see if it exists in an array and the age to check if it is of legal age. If it is, you are authorized to enter the system.

The code is not finished yet but my doubt is that I have a type method Stringthat receives a parameter called namethat is in another class and is inherited through the main class called MyNameI have two fields defined private(I should define them like this or public because I will use them the method of the other class), well then in the main class I define a constructor by which to define (initialize) by default the values ​​there is my other problem I have two objects a String object and another ID type I should define them like this or how ?

Here is the code so you can see what I have:

main class

/*Proposito del programa:
 el proposito del programa es verificar el name del usuario y ver si exsite en un array y la edad 
 verificar si es mayor de edad si lo es es autorizado a entrar al sistema.
*/

public Class MyClass extends Methods {
    public static void main(String[]args) {
    //Campos 
        private String name;
        private int edad;

        //Creo los objetos name(nombre) y edad(la edad del usuario)
        String user = new String();
        id edad = new id();
        /* Mi problema es aqui en los objetos deberia crearlos asi o como ?*/
        //Constructor 
        public MyClass {
            user.Getname = "Gilberto quintero";
        }
        Scanner entrada = new Scanner(System.in);   
    }    
}

the other class

public Class Methods {
    public String Getname(String name) {
        System.out.println("Hola bienvenido a"+name);
    }    
}

I don't see any functionality in an anonymous class.

Could someone explain to me what it can help me with?

Unfortunately, I don't get it. Of course I read its documentation in Oracle, but I don't see a use in production that works, I see it as if it were a method.
