Question 1: What third-party modules does this project use? What are they? What are their versions? How did you find that information?

Question 2: Who are the contributors for socket.io module? List their names and email addresses.

Question 3: What do you need to do if the event name ‘chat message’ is changed to ‘trump’ in index.html file so that the application doesn’t break?

var socket = io();

$('form').submit(function(){

socket.emit('trump', $('#m').val());

$('#m').val('');

return false;

});

socket.on('trump', function(msg){

$('#messages').append($('<li>').text(msg));

});

index.js:

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

app.get('/', function(req, res){
  res.sendFile(__dirname + '/index.html');
});

io.on('connection', function(socket){
  socket.on('chat message', function(msg){
    io.emit('chat message', msg);
  });
});

http.listen(3000, function(){
  console.log('listening on *:3000');
});

When multiple thread access the setLower and setUpper methods of the NumberRange object, the isValid method return false. Explain why?

public class NumberRange {

private final AtomicInteger lower = new AtomicInteger(0);

private final AtomicInteger upper = new AtomicInteger(0);

  public void setLower(int i) {

if(i>lower upper.get()) throw new IllegalArgumentException();

lower.set(i);

}

public void setUpper(int i) {

if (i < lower.get()) throw new IllegalArgumentException();

upper.set(i);

}

public boolean isValid() {

return (lower.get() <= upper.get());

}

}

Directions:

Using a vector of integers that you define.

Write a C++ program to run a menu driven program with the following choices:

1) Display the ages
2) Add an age
3) Display the average age
4) Display the youngest age
5) Display the number of students who can vote
6) Remove all students less than a given age
7) Quit

Make sure your program conforms to the following requirements:

1. Write a function called getValidAge that allows a user to enter in an integer and loops until a valid number that is >= 0 and < 120 is entered. It returns the valid age.

2. Write a function called displayAges that takes in a vector of integers as a parameter and displays the ages in the format in the sample run below.

3. Write a function called AddAge that takes in a vector of integers by reference as a parameter, asks the user to input a valid age, and adds it to the vector of integers .

4. Write a function called getAverageAge that takes in a vector of integers as a parameter, computes, and returns the average age.

5. Write a function called getYoungestAge that takes in a vector of integers as a parameter, computes, and returns the youngest age.

6. Write a function called getNumStudentsVote that takes in a vector of integers as a parameter, computes, and returns the number of ages in the vector that are >= 18. (15 points).

7. Write a function called RemoveStudentsLessThanSelectedAge that takes in a vector of integers as a parameter, asks the user for an age, creates a new vector of integers that only contains the ages in the parameter vector which are >= the age selected by the user and returns the new vector.

8. Add comments wherever necessary.

NOTE: You must take care of the case when the vector is empty and an operation is being performed on it. In such cases the program should display a 0 for the given result.

General Requirements:

1. Please make sure that you're conforming to specifications (program name, print statements, expected inputs and outputs etc.). Not doing so will result in a loss of points. This is especially important for prompts.

2. If we have listed a specification and allocated point for it, you will lose points if that particular item is missing from your code, even if it is trivial.

3. No global variables (variables outside of main() ) unless they are constants.

4. All input and output must be done with streams, using the library iostream

5. You may only use the iostream, iomanip, and vector libraries. Including unnecessary libraries will result in a loss of points.

6. NO C style printing is permitted. (Aka, don't use printf). Use cout if you need to print to the screen.

7. When you write source code, it should be readable and well-documented (comments).

Design the topic and write a 500-word abstract on the Spark technology. Define the technology and explain why it is indeed disruptive Show your understanding on its importance in industry. Site industry examples of use. Understand how and where it can be used in relation to Enterprise Computing. Why is it important? Site at least 5 references to show your research and use proper grammar and writing discipline. Note: Paper must include all 5 discussion points in content for grading. 50 points.

I am doing a paper in which I have to find the following information:

two web design theories. an example given is Gestalt

two web best practices, an example given is CSS

two technologies, an example given is HTML5

Are there any others? I am kind of lost here. I have no idea what theories, practices or technologies there are out there. Can someone give me a run down of several?

Recall the linear search algorithm:

procedure linear search (x: integer, a1, a2, ..., an: distinct integers)

i := 1

while (i ≤ n and x 6= ai) i := i + 1 if i ≤ n then location:= i else location:= 0 return location

Apply the linear search algorithm to search for the number 3 in the list 1, 5, 3, 9.

(a) In this application of the algorithm, what is the integer n?

(b) What is the initial value of i?

(c) How many iterations of the while loop occur when applied to this list?

(d) What is the value of i after the while loop finishes its iterations?

(e) What does the algorithm return?

Enter month of the year -> 10

Enter the year -> 2019

Finding: There are not five Monday dates in October of 2019.

Using JavaScript for the following assignment

Design and code a function named "intersection" that

takes two arrays of numbers in parameter and returns a new

array containing only the values that are both in the

two arrays. A value must not be found more than once in

the resulting array but can be found more than once in

the arrays in parameter. The order of the elements in the resulting array

must respect the order of the first parameter. For example :

      intersection ([3, 1, 4, 1, 5], [2, 4, 4, 3])

must return [3, 4].

You also need to design and code a unit test function and

call it. To test that the result of

      intersection ([3, 1, 4, 1, 5], [2, 4, 4, 3])

which returns [3, 4], you can use a test like this:

      assert (intersection ([3, 1, 4, 1, 5], [2, 4, 4, 3]) == "3,4");

This works because the == operator does the automatic conversion

from arrays to text (if one of the two operands are a text).

Compare and contrast an Ethernet frame with a different layer 2 frame header. How are they different?

Compare the Cisco ISO CLI to another Cisco CLI platform. How are they similar and how are they different?

Look at an Ethernet frame and review the header. Take five items that are included in the frame header and explain their function.

Create a Packet Tracer file that completes the required steps below.

Add two Cisco 2960 switches and wire it up accordingly; use a crossover cable.

After you have added the switches, add the following devices and wire accordingly.

Configure the following information on the computers:

Configure the following items:

• Set passwords for the Console and VTY 0 4 lines.
• The password should be set for login and the password should be "P@ssword#1".
• Set a enable password that is a secret; the password should be "P@ssword#2".
• Set a banner that is appropriate.
• Set the hostname as appropriate.
• Enable the service for securing passwords.

In Python: read in 'marks.txt' . The file format is one number per line. Your program will run through all these numbers, and make sure that they are valid input.

you have to Create two lists: one for valid numbers and one for invalid numbers.

For a number to be valid the number has to:

Must be less than or equal to 100

Must be greater than or equal to 0

Must not have any letters inside of it (it must be numeric -- use the string function .isnumeric())

Print out list of bad inputs, and print out average of the good inputs.
