Proxy for Periscope

Technically, a proxy is an ordinary computer or server connected to a network (local or Internet). It accepts traffic from the user, redirects it to the address that was specified in the request. And then receives the response from the server and transmits it to the user's equipment. That is, it is actually an intermediary.

To scrape JSON data using RxJava in a Java application, you can use the RxJava library along with an HTTP client library to make requests. Below is an example using RxJava2 and OkHttp to scrape JSON data from a URL asynchronously.

Add Dependencies

Add the following dependencies to your project:

    io.reactivex.rxjava2
    rxjava
    2.x.y 




    com.squareup.okhttp3
    okhttp
    4.x.y 

Write the Code:

import io.reactivex.Observable;
import io.reactivex.schedulers.Schedulers;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class JsonScrapingExample {

    public static void main(String[] args) {
        String url = "https://api.example.com/data"; // Replace with your JSON API URL

        // Create an Observable that emits a single item (the URL)
        Observable.just(url)
                .observeOn(Schedulers.io()) // Specify the IO thread for network operations
                .map(JsonScrapingExample::fetchJson)
                .subscribe(
                        jsonData -> {
                            // Process the JSON data (replace this with your scraping logic)
                            System.out.println("Scraped JSON data: " + jsonData);
                        },
                        Throwable::printStackTrace
                );
    }

    // Function to fetch JSON data using OkHttp
    private static String fetchJson(String url) throws Exception {
        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder()
                .url(url)
                .build();

        try (Response response = client.newCall(request).execute()) {
            if (!response.isSuccessful()) {
                throw new Exception("Failed to fetch JSON. HTTP Code: " + response.code());
            }

            // Return the JSON data as a string
            return response.body().string();
        }
    }
}

2. • Replace the url variable with the actual URL of the JSON API you want to scrape.
   • The fetchJson function uses OkHttp to make an HTTP request and fetch the JSON data.

3. Run the Code:

   • Execute the Java code to fetch and process the JSON data asynchronously using RxJava.

This example uses RxJava's Observable to create an asynchronous stream of events. The observeOn(Schedulers.io()) part specifies that the network operation (fetchJson) should run on the IO thread to avoid blocking the main thread.

Make sure to handle exceptions appropriately and adjust the code based on the structure of the JSON API you are working with.

To receive and display a video stream via UDP protocol on a C# server, you can use the UdpClient class from the System.Net.Sockets namespace. Here's a simple example of how to set up a UDP server that receives a video stream and displays it on a Windows Forms application:

1. Create a new Windows Forms Application project in Visual Studio.

2. Add a PictureBox control to the form.

3. Double-click on the PictureBox to create a new method named pictureBox1_Click.

4. Add the following code to the pictureBox1_Click method:

using System;
using System.Drawing;
using System.Net;
using System.Net.Sockets;
using System.Threading;
using System.Windows.Forms;

namespace UDP_Video_Stream
{
    public partial class Form1 : Form
    {
        private const int Port = 12345;
        private byte[] _buffer = new byte[1024 * 1024]; // 1MB buffer
        private UdpClient _udpClient;
        private Thread _receiveThread;

        public Form1()
        {
            InitializeComponent();
            InitializeUdpClient();
        }

        private void InitializeUdpClient()
        {
            _udpClient = new UdpClient(Port);
            _udpClient.EnableBroadcast = true;
            _receiveThread = new Thread(ReceiveVideoStream);
            _receiveThread.Start();
        }

        private void ReceiveVideoStream()
        {
            while (true)
            {
                try
                {
                    IPEndPoint remoteEndPoint = new IPEndPoint(IPAddress.Any, 0);
                    int receivedBytes = _udpClient.Receive(ref remoteEndPoint);

                    byte[] frame = new byte[receivedBytes];
                    Array.Copy(_buffer, frame, receivedBytes);

                    // Process the received frame (decode, display, etc.)
                    ProcessFrame(frame);
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                }
            }
        }

        private void ProcessFrame(byte[] frame)
        {
            // This method should be implemented to process the received frame.
            // For example, you can decode the frame using a library like FFmpeg and display it on the PictureBox.
            // Note that this is a complex task and requires additional libraries and code.
        }

        private void pictureBox1_Click(object sender, EventArgs e)
        {
            // This method is called when the PictureBox is clicked.
            // You can add any additional logic here if needed.
        }
    }
}

This code sets up a UDP server that listens on port 12345 and receives video frames. The ProcessFrame method should be implemented to process the received frame, which may involve decoding the frame

In e-mail, proxy servers are used for secure data exchange as well as for collecting e-mails from several e-mail addresses at once. For example, this is how Gmail works, which also allows you to receive e-mails from mail.ru and other e-mail services.

Telegram is a popular messenger, the activity of which is prohibited in some countries. It is possible to bypass the blocking with the help of anonymous proxy-servers working on the SOCKS5 protocol. They redirect traffic from Telegram to third-party IP addresses from other countries. Proxy servers guarantee the anonymity of correspondence, allow you to create chatbots, promote several accounts simultaneously, which will not be afraid of blocking.
