- Mass Downloader Objectives: 1. Learn how to Retrieve objects over an HTTP connection. 2. Learn how to extract links from and an HTML file. Equipment and Software Tools Required: 1. PYTHON 2. urllib module 3. regex module Introduction: In some cases, you reach a website that has a list of objects (links) you want to download. This could be a course website with a list of the slides in PDF format. Therefore, you can use an application or browser extension that provides mass or batch downloading, such as Flashget and Chrono Download Manager. Those applications/extensions extract all links from the HTML file, give you the option to select the ones to download, and it will download all selected objects. In this lab exercise, you are going to write a script that will work as a mass downloader. Requirements In this exercise, the learner should write a mass downloader script. The script should download all links of a certain type from a given website. Therefore, the script should do the…***Please Answer with code*** Your goal is to create a PHP driven website for selling Computer Science textbooks. Your site MUST include the following: 1. An Index page which includes menus for different subjects (Networking, programming, security). 2. Each subject page must allow the user to select and order more than one book at a time. When the user has selected the book, they should be requested to enter their student id number to reserve the book. They can also select a check box, which "charges their account on file" for the book. This also allows them to have curb side pickup. If the user does not check the box, the site will let them know the book will be on reserve for them to pick up for the next 24 hours. Once the time expires the book will be returend to the shelve. 3. All information entered by the user must be verified. Check for: correct type (numbers/strings), missing information, invalid format (such as invalid student id format). An error message must display allowing…Computer Science Objective:To add scripting to the existing web page and work with JavaScript Es-6 features like class, object , getter methods and collection.

Create an adjacency list based on the given graph. B A с E D F GWhich of the following are true about code reuse. Select all that apply. Group of answer choices 1. Code on the internet is tested by everyone who downloads it, so it is well tested and is almost always a good choice for code reuse. 2. While programming, as long as our code passes its test, we don’t need to make any other considerations for how it might be reused. 3. It is better to reuse code that is already being used instead of implementing new code from scratch, because the currently used code becomes robust with age. 3. Reuse of code decreases the amount of programming time.Lab Assignment 2: Playfair Cipher Overview: You are required to use the Playfair cipher to encrypt the message: "Butch."

This set of exercises requires a functioning webserver to interpret the PHP code. Exercise 7-1 Checking for POST 1. 2. Test lab7‐exercise7-1.php in a browser and notice that it contains a simple one field form that posts the results back to itself. The first thing to do is detect whether the page was reached through a get (a link followed) or whether the page was arrived by the form being posted. Edit the displayPostStatus() function as follows and test. function displayPostStatus() { if ($_SERVER["REQUEST_METHOD"] == "POST") { echo "Post detected"; } else { echo "No Post Detected"; } } Now when you post the form you see the post detected, and when you enter the URL and hit enter (GET) it does not see the POST. Next, let…Insecure Cryptographic Storage Challenge 3 The result key to this level is the same as the encryption key used in the following sub application.
