Question: Write your position (3 to 4 paragraphs) about Who Controls the Internet based on Dr. Wu

title:Hooking up

Let's say you're an entrepreneur who has an idea to build a wireless fob that finds your keys even if you left them in Virginia or Barcelona. Or say you want to design a refrigerator that transmits a signal to Safeway, instructing it to deliver a gallon of milk every time you're running low. To enter the market you will have to turn to one of the four mobile phone carriers that today exercise an oligopoly over wireless device communications: Verizon Wireless, AT&T, Sprint and T-Mobile.

Good luck. Get ready for an endless set of hurdles, including lengthy trials, revenue sharing and demands to cripple or modify features, without any guarantee of final approval. All that before your fob or fridge can transmit a tiny signal. In practice, many innovative devices never reach the market. The Big Four tend to approve only established partners whose devices fit their business plans, which is why we have yet to see all those wireless devices that were supposed to be in our future.

The firms already control what phones or devices reach Americans; 95% of cell phones are sold by the wireless carriers themselves. They strictly control phone design, blocking features that might threaten their revenue, like timers that keep track of how many minutes you've used each month. The carriers have also crippled or blocked alternative means of connecting wirelessly, like Bluetooth and Wi-Fi, because they want you to burn up minutes on their networks and charge extra fees.

The good news is that the federal government will soon have a chance to change all that and throw open America's airwaves to innovation and entrepreneurship. It will come in the form of an auction, within the next year, of the few remaining pieces of a precious national resource--licenses to the nation's wireless spectrum. This particular chunk of spectrum is becoming available because TV stations must stop using it to broadcast old-fashioned analog television by February 2009.

That's why this year's auction is so important. The Federal Communications Commission will soon deliver an initial set of rules to govern the spectrum auction. What's needed to spur innovation is a simple requirement: that any winner of the auction respect a rule that gives consumers the right to attach any safe device (meaning it does no harm) to the wireless network that uses that spectrum. It's called the Cellular Carterfone rule, after a 1968 decision by the FCC in a case brought by a company called Carter Electronics that wanted to attach a shortwave radio to AT&T 's network. That decision resulted in the creation of the standard phone jack. Applying the Carterfone rule to the next spectrum auction would ensure that our key fob designer need only look up standard technical specifications and then build and sell his device directly to the consumer. The tiny amounts of bandwidth the fob used would show up on the consumer's wireless bill.

The right to attach is a simple concept, and it has worked powerfully in other markets. For example, in the wired telephone world Carterfone rules are what made it possible to market answering machines, fax machines and the modems that sparked the Internet revolution.

Attachment rights can break open markets that might otherwise be controlled by dominant gatekeepers. Longshot companies like Ebay or YouTube might never have been born had they first needed the approval of a risk-averse company like AT&T. If you've invented a new toaster, you don't have to get approval from the electric company. Consumers decide how good your product is, not some gatekeeper.

But who has the political courage to push such ideas? To date, House Representatives Edward Markey (D--Mass.) and John Dingell (D--Mich.) have taken the lead in Congress by holding hearings on the issue. John McCain is the only presidential candidate so far to take a serious interest. Others should take notice. If America's reputation as the world's leading innovator is to be sustained, we need to get wireless policy right.

PLEASE WRITE CLEAR AND CONCISE CODE

Subject is Unix system programming

Write code that downloads all of the log files ending in `.log` in an S3 bucket and counts the total number of HTTP errors in those logs.

Log lines are in the format `{"path": "/", status: 200}` or `{"path": "/", status: 404}`, for example. (This is JSON, and you can process it as such if you choose.)

Use the bucket `class6-logs`, the access key ID "AKIASUMBPHIPY6DLZ4C5", and the secret access key "JQdQIbxsRcipnoKFnsfse44SMRGouzz4tbAzTYbe".

Use the code below  to get started:

Code-

import boto3

client = boto3.client(

's3',

aws_access_key_id="AKIASUMBPHIPY6DLZ4C5",

aws_secret_access_key="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",

)

resp = client.list_objects(Bucket='class6-logs')

client.download_file('class6-logs', resp['Contents'][0]

['Key'], 'downloaded_file')

# for object in resp['Contents']:

# print(object['Key'])

# print(resp['Contents'][0]['Key'])

how to get this to not consider 0, 1 and negative integers as prime. maybe using a "nested loop" or more than one loop?

//TestCode.java import java.util.Scanner; public class TestCode { public static void main(String[] args) { // Creating scanner object Scanner scan = new Scanner(System.in); boolean isPrime; int x; // Declaring an array with 10 ints int arr[] = new int[10]; // Reading values from user System.out.println("Enter 10 integer values for array:"); for(int i = 0;i<arr.length;i++){ arr[i] = scan.nextInt(); } // Looping through each value in array for(int i = 0;i<arr.length;i++){ x = arr[i]; // Assuming x is prime isPrime = true; // Loop through 2 to x-1 for(int j = 2;j<x;j++){ // if x is divisible by any of j if(x%j == 0) { // Then setting isPrime to false isPrime = false; } } // Printing value of x if it is a prime if(isPrime){ System.out.println(x); } } } }

This is in Python, I am trying to create a new window to print the data to screen, it prints fine in the terminal. I know this is a small segment of my code and its the only portion I am having a problem with. I was wondering if anyone can see what my problem may be. The current issue is

NameError: name 'fltVal' is not defined and AttributeError: 'PressureGUI' object has no attribute 'r_count'

Any help would be appreciated Based on the comment I made some changes which got me past the error above

The updated code is now with a new error of

I know it has to do with line 12 below but I am confused at this point

My output should be barometric pressue in the format of 1028.95 in one column and temp in the second column

CIT 149 JAVA 1 programming question.

The Assignment

This program will display a menu to the user from which they can choose an option to find the area of a rectangle, the area of a triangle, or to quit.
The user will make the selection and will be prompted to enter the height and width, or the base and height, depending upon which selection they made. The program will then calculate the appropriate area and display the results.
This program will be in two classes, each in a separate file. One will contain the main method and the other will contain instance variables and methods which make up the program.

? Specifications

There are several ways in which this program could be written. However, in order to grade for following specifications and to have a clear path to a solution, it is required that you write your program using the specifications below.

• Use two separate files with a single class in each one.
  Name the first file (and class) Area. This is the one that will have all of the methods other than the main method. Name the second file AreaRun. This file will contain the class that has the main method and the logic which controls the program.

The Instance Variables

• In the class called Area, you will need to create the following instance variables. Each of these Variables will be private.
  • area
  • firstDimension
  • secondDimension

Constructing the Methods

Create the following methods:

? All of the methods below will be in the class Area.

1. menu()

   • This method will display a menu with three options (see example above):
     • 1. Area of a Rectangle
     • 2. Area of a Triangle
     • 3. Quit
   • This method will return the user’s selection from the menu (int of 1, 2, or 3).
   • This method will contain a loop which will hold the user until a valid selection is made (see menu example above).
   • This method does not have parameters.

2. setFirstDimension() (Mutator)

   • This method will accept one argument which will be a double.
   • This method will set the value of the instance variable called firstDimension in the Area class.
   • This method will contain a test of the argument coming in, to see that it is > 0. If it is less than zero, a message will be displayed and the program will end (see example above).

3. setSecondDimension() (Mutator)

   • This method will accept one argument which will be a double and will set the instance variable secondDimension in the Area class.
   • • This method will contain a test of the argument coming in, to see that it is > 0. If it is less than zero, a message will be displayed and the program will end (see example above).
   • This method will not return a value.

4. areaOfRectangle()

   • This method will be a void method and does not have parameters. It will simply calculate the area of a rectangle:
     • area = firstDimension * secondDimension
     • Use the same variable names as given above.

5. areaOfTriangle()

   • This method will be a void method and does not have parameters. It will simply calculate the area of a rectangle:
   • area = (firstDimension * secondDimension) / 2
   • Use the same variable names as given above.

6. displayOutput()

   • This method will has three parameters: the menu selection (1 or 2), the firstDimension value, and the secondDimension value.
   • This method will display the first and second dimensions, and the calculated area of the rectangle or triangle.
   • Use if_ and else statements to test the menu selection variable passed to this method to see if the user selected the rectangle or triangle. Then make the output conform to the output specifications below.
