The tool that exists to run Selenium tests in headless mode is called "Headless Browsers". Headless browsers are browser automation tools that run without a graphical user interface (GUI). They are typically used for testing web applications without the need for a visible browser window. Some popular headless browsers include:

1. Chrome's Headless mode: Chrome's headless mode can be enabled by passing the --headless flag when launching a ChromeDriver instance.

2. Firefox's Headless mode: Firefox's headless mode can be enabled by passing the --headless flag when launching a GeckoDriver instance.

3. PhantomJS: PhantomJS is a headless browser that can be used with Selenium to run tests without a visible browser window.

4. Puppeteer: Puppeteer is a Node library that provides a high-level API to control Chrome or Chromium over the DevTools Protocol. It can be used to run tests in headless mode.

5. HtmlUnit: HtmlUnit is a headless browser that can be used with Selenium to run tests without a visible browser window.

It's important to note that the specific implementation of running Selenium tests in headless mode may vary depending on the browser and the version of the Selenium WebDriver being used.

To send a user class object over UDP, you will need to serialize the object into a format that can be transmitted over the network. Here's a step-by-step guide on how to do it in Python:

1. Import necessary libraries:

import pickle
import socket

2. Define your user class:

class User:
    def __init__(self, name, age):
        self.name = name
        self.age = age

3. Serialize the user object using pickle:

def serialize_user(user):
    return pickle.dumps(user)

4. Create a UDP socket:

def create_udp_socket(host, port):
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    sock.bind((host, port))
    return sock

5. Send the serialized user object over UDP:

def send_user(sock, user, host, port):
    serialized_user = serialize_user(user)
    sock.sendto(serialized_user, (host, port))

6. Putting it all together:

if __name__ == "__main__":
    user = User("John Doe", 30)
    host, port = "127.0.0.1", 12345
    sock = create_udp_socket(host, port)
    send_user(sock, user, host, port)

On the receiving side, you will need to deserialize the received data using pickle and create a new user object from it.

To keep only unique external links while scraping with Scrapy, you can use a set to track the visited external links and filter out duplicates. Here's an example spider that demonstrates how to achieve this:

import scrapy
from urllib.parse import urlparse, urljoin

class UniqueLinksSpider(scrapy.Spider):
    name = 'unique_links'
    start_urls = ['http://example.com']  # Replace with the starting URL of your choice
    visited_external_links = set()

    def parse(self, response):
        # Extract all links from the current page
        all_links = response.css('a::attr(href)').extract()

        for link in all_links:
            full_url = urljoin(response.url, link)

            # Check if the link is external
            if urlparse(full_url).netloc != urlparse(response.url).netloc:
                # Check if it's a unique external link
                if full_url not in self.visited_external_links:
                    # Add the link to the set of visited external links
                    self.visited_external_links.add(full_url)

                    # Yield the link or process it further
                    yield {
                        'external_link': full_url
                    }

        # Follow links to other pages
        for next_page_url in response.css('a::attr(href)').extract():
            yield scrapy.Request(url=urljoin(response.url, next_page_url), callback=self.parse)

- visited_external_links is a class variable that keeps track of the unique external links across all instances of the spider.
- The parse method extracts all links from the current page.
- For each link, it checks if it is an external link by comparing the netloc (domain) of the current page and the link.
- If the link is external, it checks if it is unique by looking at the visited_external_links set.
- If the link is unique, it is added to the set, and the spider yields the link or processes it further.
- The spider then follows links to other pages, recursively calling the parse method.

Remember to replace the start_urls with the URL from which you want to start scraping.

In the Windows Settings menu, go to "Network and Internet". At the very bottom, on the left side, find the item "Proxy server" and uncheck it so that it is no longer used. It is also desirable to uncheck the item "Automatic detection of parameters" in the section "Automatic configuration". If this is not done, there is a chance that the proxy will continue to be used. Reboot your laptop.

On smartphones, when a proxy is turned on, the corresponding indicator (the "VPN" icon) appears in the status bar. In Windows you have to go to "Settings", open "Network and Internet". Under "Proxy Server", if the item "Manual" is activated, it means that the proxy is engaged right now.
