Blazing Proxy

In Perl, regular expressions (regex) are a powerful tool for parsing and manipulating text. Below is a basic example of using Perl regex to parse text. Please note that the regex patterns and the parsing logic depend on the specific structure of your text data.

Let's assume you have a simple text string with information about people, and you want to extract names and ages. Here's an example:

use strict;
use warnings;

my $text = "John Doe, age 30; Jane Smith, age 25; Bob Johnson, age 40";

# Define a regex pattern to match names and ages
my $pattern = qr/(\w+\s+\w+),\s+age\s+(\d+)/;

# Use the regex pattern to extract information
while ($text =~ /$pattern/g) {
    my $name = $1;
    my $age = $2;
    print "Name: $name, Age: $age\n";
}

In this example:

• The text contains information about people, where each entry is separated by a semicolon.

• The regex pattern (\w+\s+\w+),\s+age\s+(\d+) is used to match names and ages. Breaking down the pattern:

  • (\w+\s+\w+): Matches names consisting of one or more word characters (letters, digits, underscores) separated by whitespace.
  • ,: Matches the comma separating the name and age.
  • \s+age\s+: Matches the string "age" surrounded by whitespace.
  • (\d+): Matches one or more digits representing the age.

• The while ($text =~ /$pattern/g) loop iterates through matches found in the text.

• Inside the loop, $1 and $2 capture the matched name and age, respectively.

To scrape images in C#, you can use the HTMLAgilityPack library for parsing HTML and retrieving image URLs. Here's a basic example

Install HTMLAgilityPack

You can install the HTMLAgilityPack NuGet package using the following command in the Package Manager Console:

Install-Package HtmlAgilityPack

Write a C# script to scrape images:

using System;
using System.Collections.Generic;
using HtmlAgilityPack;

class Program
{
    static void Main()
    {
        string url = "https://example.com"; // Replace with the URL of the page you want to scrape images from

        // Download HTML content from the URL
        HtmlWeb web = new HtmlWeb();
        HtmlDocument document = web.Load(url);

        // Extract image URLs
        List imageUrls = ExtractImageUrls(document, url);

        // Print the extracted image URLs
        foreach (string imageUrl in imageUrls)
        {
            Console.WriteLine(imageUrl);
        }
    }

    static List ExtractImageUrls(HtmlDocument document, string baseUrl)
    {
        List imageUrls = new List();

        // Select image elements using XPath
        var imageElements = document.DocumentNode.SelectNodes("//img[@src]");

        if (imageElements != null)
        {
            foreach (var imageElement in imageElements)
            {
                // Extract image URL from the src attribute
                string imageUrl = imageElement.GetAttributeValue("src", "");

                // Make the URL absolute if it's a relative URL
                imageUrl = new Uri(new Uri(baseUrl), imageUrl).AbsoluteUri;

                // Add the URL to the list
                imageUrls.Add(imageUrl);
            }
        }

        return imageUrls;
    }
}

This script uses HTMLAgilityPack to load the HTML content of a webpage and extract image URLs using XPath. The ExtractImageUrls method selects image elements with the XPath query "//img[@src]", retrieves the src attribute, and converts relative URLs to absolute URLs.

Run the script:

Replace the url variable with the URL of the webpage you want to scrape images from.

Run the script to see the list of image URLs.

Explicit and implicit waiting are two types of waiting strategies used in Selenium WebDriver to handle synchronization issues in web applications. They help in dealing with elements that are not immediately available on the page when the test starts.

Explicit Wait:

Explicit wait is used when you know exactly which element you are waiting for and how long you want to wait for that element to be available. It uses the WebDriverWait class to wait for a specified condition to be true for a specified amount of time. Explicit wait is more reliable and is generally recommended when you know the expected conditions.

The main components of explicit wait are:

- WebDriverWait: It is a class that provides a way to wait for a condition to be true for a specified amount of time.

- ExpectedConditions: It is a class that provides a way to specify the condition to be true.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Chrome()
driver.get("http://example.com")

# Explicit wait for an element to be present
wait = WebDriverWait(driver, 10)
element = wait.until(EC.presence_of_element_located((By.ID, "myElement")))

Implicit Wait:

Implicit wait is a global setting that applies to all find_element and find_elements calls in a test. It tells the WebDriver to wait for a specified amount of time for an element to be available before throwing a NoSuchElementException. Implicit wait is less reliable than explicit wait because it applies to all elements in the test, not just the specific one you are waiting for.

The main components of implicit wait are:

ImplicitlyWait: It is a method used to set the amount of time the WebDriver should wait for an element to be available before throwing a NoSuchElementException.

from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException

driver = webdriver.Chrome()
driver.implicitly_wait(10) # Set implicit wait to 10 seconds
driver.get("http://example.com")

try:
    element = driver.find_element(By.ID, "myElement")
except NoSuchElementException:
    print("Element not found")

In summary, the main difference between explicit and implicit waiting in Selenium is that explicit wait is used for waiting for a specific condition to be true for a specified amount of time, while implicit wait is a global setting that applies to all find_element and find_elements calls in a test. Explicit wait is more reliable and is generally recommended for specific scenarios, while implicit wait is less reliable but simpler to use for general cases.

The easiest option is to use ready-made online proxy checkers. For example, Hidemy.name, which shows the type of protocol used. Or you can simply run Speedtest - this will show you the bandwidth and response speed (ping).

In AnyDesk, in order to ensure maximum security of transmitted traffic, you can use proxies, including encryption of traffic. The setting is made through the regular menu of the application. You will need to go to "Options", select "Connection", specify the proxy and port number. Connection is made automatically after that.
