101 Proxy

It means organizing a connection through several VPN-servers at once. It is used to protect confidential data as much as possible or to hide one's real IP address. This principle of connection is used, for example, in the TOR-browser. That is, when all traffic is sent immediately through a chain of proxy servers.

If PyCharm Community Edition (PyCharm CE) has stopped recognizing the Selenium package, it could be due to various reasons. Here are some steps you can take to troubleshoot and resolve the issue:

1. Check Virtual Environment:

   • If you are using a virtual environment, make sure it is activated in PyCharm. Virtual environments isolate project dependencies, and if the virtual environment is not activated, PyCharm may not recognize installed packages.

2. Reinstall Selenium:

   • Try reinstalling the Selenium package in your project. Open the terminal in PyCharm and run the following command:

pip uninstall selenium
pip install selenium

• PyCharm Cache:

  • Clear the PyCharm cache, as cached information might be causing the issue. You can find the "Invalidate Caches / Restart" option under the "File" menu in PyCharm.

• Project Interpreter:

  • Make sure that the correct Python interpreter is selected for your project. Go to "File" > "Settings" > "Project: YourProjectName" > "Python Interpreter" and ensure that the interpreter matches the one where Selenium is installed.

• Check for Typos and Case Sensitivity:

  • Ensure that your import statements and references to the Selenium package are correct. Python is case-sensitive, so selenium should be in lowercase.

from selenium import webdriver

6. Restart PyCharm:

   • Sometimes, restarting PyCharm can resolve issues related to package recognition.

7. Check for Python File Naming Conflicts:

   • Ensure that there are no conflicting file names in your project. Sometimes, naming a file with the same name as a module might lead to import issues.

8. Check for Project Integrity:

   • Open your project's root directory and check if there are any issues with the project structure or files.

9. Update PyCharm:

   • Ensure that you are using the latest version of PyCharm. If not, consider updating to the latest version.

10. External Factors:

    • Check if there are any external factors affecting the Python environment, such as antivirus software or security tools.

11. Check Project SDK:

    • Confirm that the project SDK is set correctly. Go to "File" > "Project Structure" > "Project" and ensure that the correct Python interpreter is selected.

12. Check for IDE-Specific Issues:

    • Check the PyCharm forums or support channels for any known issues related to Selenium recognition in the specific version of PyCharm you are using.

After trying these steps, you should be able to resolve the issue of PyCharm CE not recognizing the Selenium package. If the problem persists, additional details about error messages or symptoms would be helpful for further assistance.

UDP (User Datagram Protocol) is a transport layer protocol that provides a simple and fast way to send data over a network. Unlike TCP, UDP does not establish a connection between the sender and receiver before sending data. Instead, UDP uses a connectionless communication model, where each datagram (data packet) is sent independently.

Here's how UDP works:

1. The sender application prepares the data to be sent and wraps it in a UDP datagram. This datagram contains the data, the source IP address, the destination IP address, and a checksum for error detection.

2. The sender application sends the UDP datagram to the network layer, which then forwards it to the appropriate network interface for transmission.

3. The datagram is transmitted over the network as a single, self-contained packet. There is no guarantee that the datagram will reach its destination, as UDP does not provide any error correction or retransmission mechanisms.

4. The receiving application listens for incoming UDP datagrams on a specific port. When a datagram arrives, the network layer forwards it to the appropriate application.

5. The receiving application processes the datagram, extracts the data, and handles any errors detected by the checksum.

It's important to note that UDP does not establish a connection between the sender and receiver. This means that there is no handshake or acknowledgment of receipt, and the sender does not know if the datagram was successfully delivered. UDP is often used for applications that prioritize speed over reliability, such as video streaming, online gaming, and VoIP (Voice over Internet Protocol).

This is a proxy server integrated into the app to redirect traffic. It allows you to protect yourself from being tracked or to use the program where it is blocked. For example, at one time, users used a proxy server to bypass Telegram blocking.

You can find out your proxy using the Socproxy.ru/ip service from your computer or cell phone. Your IP or proxy address will appear on the main page of the site. Another option is to download the SocialKit Proxy Checker utility, which you can use to check your proxy for validity. If a proxy is used in the browser settings, you can find out its parameters there as well.
