Juniper Proxy

Open the "Data and memory" item in the settings, and then, under "Proxy", click "Proxy settings". In the "Connection" window that opens, select "Add proxy" and then check the SOCKS5 proxy. Next, in the "Server" field, you must enter the IP of the proxy, and in the "Port" field enter the port SOCKS5. The next step is to enter the login from the proxy and the password from the proxy. Now, all you have to do is click "Done".

Scraping without libraries in Python typically involves making HTTP requests, parsing HTML (or other markup languages), and extracting data using basic string manipulation or regular expressions. However, it's important to note that using established libraries like requests for making HTTP requests and BeautifulSoup or lxml for parsing HTML is generally recommended due to their ease of use, reliability, and built-in features.

Here's a simple example of scraping without libraries, where we use Python's built-in urllib for making an HTTP request and then perform basic string manipulation to extract data. In this example, we'll scrape the title of a website:

import urllib.request

def scrape_website(url):
    try:
        # Make an HTTP request
        response = urllib.request.urlopen(url)
        
        # Read the HTML content
        html_content = response.read().decode('utf-8')

        # Extract the title using string manipulation
        title_start = html_content.find('', title_start)
        title = html_content[title_start:title_end].strip()

        return title
    except Exception as e:
        print(f"Error: {e}")
        return None

# Replace 'https://example.com' with the URL you want to scrape
url_to_scrape = 'https://example.com'
scraped_title = scrape_website(url_to_scrape)

if scraped_title:
    print(f"Scraped title: {scraped_title}")
else:
    print("Scraping failed.")

Keep in mind that scraping without libraries can quickly become complex as you need to handle various aspects such as handling redirects, managing cookies, dealing with different encodings, and more. Libraries like requests and BeautifulSoup abstract away many of these complexities and provide a more robust solution.

Using established libraries is generally recommended for web scraping due to the potential pitfalls and challenges involved in handling various edge cases on the web. Always ensure that your scraping activities comply with the website's terms of service and legal requirements.

Parsing huge XML files can be challenging due to their size. Here are some tips for efficient XML parsing:

1. Use Streaming Parsers:

   • Streaming parsers, like SAX (Simple API for XML) or StAX (Streaming API for XML), process XML data sequentially. They don't load the entire XML document into memory, making them memory-efficient for large files.

2. XPath for Selective Parsing:

   • XPath is a query language for XML that allows you to navigate through elements and attributes. Use XPath to selectively parse only the parts of the XML document that you need, rather than parsing the entire file.

3. Incremental Parsing:

   • Break the XML document into smaller chunks and parse them incrementally. This can be useful when dealing with extremely large files. Process one chunk at a time instead of loading the entire file into memory.

4. Memory Management:

   • If using a DOM (Document Object Model) parser, be mindful of memory usage. Large XML files can consume a significant amount of memory when loaded into a DOM. Consider using a streaming approach instead.

5. Parallel Processing:

   • If the XML document is partitioned into multiple sections, you can leverage parallel processing to parse different sections concurrently. Be cautious with synchronization to avoid conflicts.

6. Compression:

   • If the XML files are too large, consider compressing them before parsing. This can reduce the file size and speed up the parsing process. Remember to decompress the file before parsing.

7. Optimize Code and Libraries:

   • Ensure that you are using an efficient XML parsing library. Some libraries are better optimized for large files. Additionally, optimize your code for performance by minimizing unnecessary operations.

8. Use Memory-Mapped Files:

   • Memory-mapped files allow parts of a file to be mapped directly into memory. This can be beneficial for random access to different parts of a large XML file.

9. Consider External Tools:

   • In some cases, using external tools specifically designed for processing large XML files might be a good option. These tools are often optimized for performance and memory usage.

Remember that the optimal approach may vary depending on the specific requirements of your application and the characteristics of the XML files you are dealing with.

It depends on how you plan to log in to Facebook. For example, if on a PC, just specify the proxy server settings in the connection properties or in the browser settings. If on a mobile (site or application), you need to specify the proxy data in the settings of the phone itself. Or you can install an application that allows you to automatically set up a VPN connection.

A proxy server is a kind of "mediator" between your equipment and a remote server (or the whole Internet). It can be used, for example, to swap your real IP address for another one, to bypass blocking. Proxies can also be actively used to intercept traffic (e.g. when testing created web applications).
